What should be noted for the protection of underwater fountain lights?
Fountain equipment color light protection:
Underwater lanterns are easily damaged components of fountain engineering equipment, so daily maintenance of lanterns is also extremely important. Waterproof with heat shrink tubing and hot melt adhesive for colored lights; When assembling the colored lights, the connection between the lights and the lamp frame should be tight and not loose; When welding light bulbs on pipelines, they must be tightly welded to prevent them from falling off during use; After assembly, it should be immersed in 5% saline solution for 72 hours, and the resistance value should be measured to be qualified before use.
1. Water replenishment requirements for fountain projects
Fountain water should be recycled. When there are requirements for the nozzle, the circulating water should be filtered. The amount of supplementary water for the circulation system should be determined based on losses such as evaporation, wind blowing, leakage, and discharge, and generally should be 5-10% of the circulation flow rate.
2. Maintenance of nozzle
The nozzle should be cleaned and maintained regularly, and attention should be paid to the tightness of the connection between the nozzle and the pipeline during installation. When installing the nozzle, a layer of raw material tape should be wrapped around the threaded part of the pipeline to avoid water leakage and affect the spraying effect. At the same time, anti-theft measures should be taken for the nozzle.
3. Maintenance of underwater colored lights
Underwater colored lights are easily damaged components in fountain components. To reduce the damage rate of colored lights, the following points should be noted:
(1) When welding light bulbs on pipelines, they must be welded tightly to prevent them from falling off during use.
(2) When assembling lighting fixtures, the colored lights should be securely connected to the lamp frame without loosening.
(3) After the assembly of the lighting fixtures, they should be immersed in 5% saline water for 72 hours, and the resistance value should be measured and qualified before use.
(4) The underwater joint should be properly connected and waterproofed with heat shrink tubing and hot melt solution.
4. Water quality requirements for fountains
The water quality of the supplied water should meet the sensory characteristics requirements specified in the current "Sanitary Standards for Domestic Water", namely:
The chromaticity shall not exceed 15 degrees, and no other abnormal colors shall be present. The turbidity shall not exceed 10 degrees; It shall not contain visible substances to the naked eye.
5. Pipeline of fountain pool
The fountain should be equipped with water distribution pipes, return pipes, overflow pipes, drainage pipes, and drainage facilities for the water distribution pipes. A filter screen should be installed on the return pipe. The fountain water distribution pipe should be arranged in a circular shape, and the head loss of the water distribution pipe should generally be 5-10mm/m. The water distribution pipe joints of the fountain should be tight and smooth, and reducers should be used at the pipe diameter changes. Smooth elbows with large turning radii should be used at the pipe bends. There should be a straight pipe section or a rectifier device with a diameter not less than 20 times the nozzle diameter in front of the nozzle.
On the basis of controlling the fountain through a program, a music control system is added. The computer recognizes, decodes, and encodes audio and MIDI signals, and outputs the signals to the control system to synchronize the shape and lighting changes of the fountain with the music. This achieves the combination of changes in fountain water type, lighting, and color with music emotions, making the fountain performance more vivid, meaningful, and reflecting the art of water.
With the development of the economy and the improvement of people's living standards, people are paying more and more attention to the improvement and beautification of their living environment. In urban construction and planning, people have put forward higher requirements for the construction of leisure places, and the construction of various leisure squares and parks is also becoming more and more beautiful. Among them, the music fountain system, which combines sound, light, water, and color, has become an important part of urban landscape construction. Large and medium-sized cities in China have been competing to build music fountains and are developing towards small cities. And for daily maintenance, China's current performance is not good enough. Below, we will explain what needs to be paid attention to in the daily maintenance of music fountains.
1、 Personnel who provide professional training for fountain equipment maintenance personnel and electrical equipment maintenance personnel also need to hold professional job certificates.
2、 The maintenance and repair of electrical equipment should be carried out under the condition of cutting off the power supply. If live operation is required in special circumstances, safety protection measures should be taken, and special personnel should be assigned to monitor important parts.
3、 The underwater lights of the fountain should be checked and tightened once a month for loose screws (paying special attention to running springs) to avoid short circuit faults caused by water ingress into the lamp body.
4、 Backup equipment should be started and operated regularly (replace high-frequency equipment once a day and low-frequency equipment once a day) to prevent equipment performance degradation.
5、 The water pump suction port should be cleaned monthly to prevent dirt from blocking the suction port, reducing efficiency, and even causing equipment damage.
6、 The connection of waterproof cables must be carried out under waterless conditions and protected with three layers of waterproof tape, insulation tape, and high-voltage insulation tape.
7、 During the winter shutdown period of the fountain submersible pump, the cooling water must be drained to avoid freezing and damaging the pump body. (Valves need to be closed for oil cooling)
8、 Before the winter fountain is stopped, the water in the pipeline should be drained to prevent the pipeline from freezing and cracking.
9、 The fountain needs to be cleaned every six months, and attention should be paid to the nozzle riser and underwater lights during cleaning to prevent damage.
10、 When replacing the diaphragm of the solenoid valve, all objects that have fallen off in the pipeline should be cleaned and dried; Tighten the screws in diagonal order.
11、 The replacement of underwater lights must be carried out without water and the bolts must be securely fastened.
1. LED underwater low-voltage color light: Its main advantages are long lifespan (about 100000 hours), low energy consumption (3W~15W), safe low voltage (6V~36V), cold light environmental protection (as a cold light source, no purple, infrared radiation, no flicker), easy waterproofing, etc. It is currently widely used for underwater lighting in fountains.
2. Underwater highlight lights: Underwater highlight lights are used to illuminate fountains with high spray, which can be as low as 20-30 meters or as high as over 100 meters, and have special lighting requirements. Due to their high illumination, underwater highlight lights mostly use thermal light sources such as metal halide lamps and sodium lamps, which generate a large amount of heat during lighting, resulting in extremely high waterproof treatment requirements. Due to the low demand for underwater high gloss lamps and the lack of mature products to choose from in the market, professional fountain companies generally adopt professional customization for the production of underwater high gloss lamps.
3. Other underwater lights: There are also varieties of underwater lights that use incandescent or energy-saving lamps as light sources, but due to inherent defects in their illumination, environmental performance, and service life, their usage rate is currently decreasing.
In the design of some water feature fountains, lighting effects are equipped to make the use of the fountain more prominent. However, for the lighting in the fountain, careful selection should be made from the following aspects.
Firstly, regarding the safety of lighting, there are usually corresponding standards to regulate it. Underwater colored lights with a safe voltage of 12V are an ideal choice for ensuring safety.
Secondly, it is necessary to have certain lighting functions. Fountain lighting is not only configured for aesthetic purposes, but also has practical functions, so requirements need to be made for luminous brightness. We need to choose fountain colored lights of different powers based on factors such as illumination height, area, and application scenarios.
There are also material requirements. Although it is used in fountains, the appearance and material factors should also be considered. It is necessary to have a certain anti-corrosion function while paying attention to the specific gravity of the material. Afterwards, economy is a concern for all products, and the application of fountain lights is no exception.
1. Appearance and shell material:
12、 To achieve a beautiful fountain pattern, the nozzle with changing angles should be reset at any time. Sharp objects should not be used to strike the nozzle during resetting to prevent damage.
13、 The fountain electrical equipment should be regularly maintained, and the vulnerable electrical equipment in the cabinet should be inspected and maintained as necessary every six months.
14、 Computers need to be upgraded every year to perform necessary maintenance on computers and programs.
15、 Check the aging of wires and cables that are not in the water every six months to avoid unnecessary losses.
16、 Assess the operators of the fountain every six months and strengthen usage management.
17、 Clean and maintain the fountain pipeline once a year.
18、 Maintain and upkeep the swing mechanism of the fountain pump annually.
Although underwater lanterns are used underwater in water feature fountains, they are not very eye-catching. But the appearance and material are related to the proportion of the lighting fixtures. If the specific gravity is too small, it will generate a large buoyancy, which can easily loosen the fixing screws of the underwater lantern, causing the lamp to float on the water surface, while being too heavy makes it difficult for the lamp holder to support. At the same time, due to long-term use in water, the shell material should have a certain anti-corrosion function, and the surface paint layer should be firm.
2. Economic viability
The economy of underwater color lights in a fountain refers to the total investment and operating costs of the lighting fixtures. Generally speaking, high-quality underwater color lights have higher prices, longer service lives, and lower operating costs. Conversely, low-quality underwater color lights, although cheaper, often suffer from blindness due to water and electricity leakage, which not only increases operating costs but also affects the acceptance of the entire project.
3. Security function:
The selection of underwater colored lights in water feature fountain landscape places takes personal safety as an element. Underwater color lights with a safe voltage of 12V must be used in accordance with national standards.
4. Lighting function:
The brightness function mainly refers to the luminous intensity of the light source. It can select underwater lights of different powers based on the illumination height and projection area. Another element of lighting function is the color of underwater colored lights, which generally have five types: red, yellow, green, blue, and white, and can be selected according to the application, illuminated object, and created atmosphere.
