Description

Technical Field

[0001] The present application relates to the field of photovoltaic cleaning technology, and more specifically, to a photovoltaic cleaning water film spraying device. Background Art

[0002] During the manufacturing process of photovoltaic silicon wafers, some processes require cleaning and processing on the bottom surface of the silicon wafer, such as etching. In order to prevent the top surface of the silicon wafer from being corroded by the etching liquid, a water film needs to be formed on the top surface to protect the top surface from corrosion. Water film coverage is to spray water or other liquids evenly on the top surface of the silicon wafer through a sprinkler head.

[0003] Chinese patent announcement number: CN115841974B discloses a photovoltaic cleaning water film spraying device, which consists of a tank body and a spray head. The tank body includes a main tank and an overflow tank divided by an overflow plate. The main tank is provided with a water inlet pipe, and at least one water outlet is provided on the side plate along the length direction of the main tank. The side plate of the overflow tank is provided with an overflow port. During operation, the liquid is sprayed from the spray head through the spray pipe to form a water film on the top surface of the photovoltaic silicon wafer while keeping the liquid in the main tank in an overflow state. During spraying, the overflow is maintained at the same time to keep the water level in the main tank constant, thereby keeping the water pressure of the spray head constant, and then keeping the flow rate out of the spray head constant, thereby improving the stability of the water film quality.

[0004] Traditional photovoltaic cleaning methods are mostly water film spray cleaning technology, which forms a thin layer of water film on the surface of the photovoltaic panel and uses the flow of water and gravity to remove pollutants, thereby cleaning the photovoltaic panel. However, the existing water film spray cleaning equipment still has some problems in wastewater treatment and reuse: For example, wastewater after cleaning is often discharged directly into the environment, which not only wastes water resources but also may pollute the environment. Even if the used water is filtered, the filtering mechanism is relatively simple and the filtering effect is poor. In addition, in some cold weather conditions, the water used for spraying is easy to freeze in the water tank, affecting the normal operation and cleaning effect of the equipment.

[0005] In order to solve the above problems, the present invention proposes a photovoltaic cleaning water film spraying device, which aims to achieve effective recovery and reuse of sewage through innovative design and technical means, while preventing water in the water tank from freezing, thereby improving cleaning efficiency and water-saving effects.

[0029] A photovoltaic cleaning water film spraying device according to an embodiment of the present application is described below with reference to the accompanying drawings.

[0030] like Figure 1 and Figure 2 As shown, a photovoltaic cleaning water film spraying device according to an embodiment of the present application includes a return water pool 1 for recycling sewage, a drain pipe 11 is arranged at the lower side of the return water pool 1, and a valve can be installed on the drain pipe 11 for discharging sewage inside the return water pool 1.

[0031] An electric roller 2 is installed at the upper end of the return water tank 1. The electric roller 2 consists of a series of rollers arranged in parallel. These rollers are driven to rotate by a motor, thereby driving the photovoltaic panels placed thereon to move. Slide rails 3 higher than the electric roller 2 are arranged on both sides of the electric roller 2. A water film spraying mechanism is slidably installed in the slide rails 3. The water film spraying mechanism sprays the photovoltaics. The sprayed liquid forms a water film on the surface of the photovoltaics, thereby achieving the effect of gently cleaning the photovoltaics and preventing the photovoltaics from being damaged during cleaning. The sewage after cleaning enters the return water tank 1 from the gap of the electric roller 2 for recovery.

[0032] A water tank 9 is provided on one side of the return water pool 1 for storing clean water after secondary filtration and external water source. The filtered water in the water tank 9 is pumped into the water film spray mechanism by a water pump 46. Specifically, Figure 1 and Figure 3As shown, the core component of the spray mechanism is composed of a pair of parallel spray pipes 4. A plurality of spray heads 41 are evenly installed on the lower side of each spray pipe 4 to ensure comprehensive and uniform spray coverage. A slider 2 44 is fixedly installed at one end of the pair of spray pipes 4. A slider 1 42 is installed on the water inlet pipe 43 at the other end of the spray pipe 4. The water inlet pipe 43 can be made of a hard pipe so that the water inlet pipe 43 passes through the slider 1 42 to ensure stable water flow transmission. The slider 1 42 and the slider 2 44 slide in the two sets of slide rails 3 respectively. Therefore, when the slider 1 42 and the slider 2 44 slide in the slide rail 3 The positions of the two groups of spray pipes 4 can be adjusted so as to be adjusted according to the size of the photovoltaic panel to improve the cleaning effect. The water inlet end of the water inlet pipe 43 is connected to the water outlet end of the water tank 9 by a connecting pipe 45. The connecting pipe 45 can be made of a soft pipe. This soft pipe not only allows the spray pipe 4 to move along the slide rail 3, but also has a length sufficient to meet the maximum displacement requirement without affecting the spraying operation. The water pump 2 46 is installed on the connecting pipe 45, and the two groups of spray pipes 4 are respectively connected to the water tank 9 through two connecting pipes 45 and two groups of water pumps 2 46 to meet the requirement of pumping liquid into the two groups of spray pipes 4.

[0033] like Figure 5 As shown, a bidirectional screw rod 31 is rotatably arranged in one of the slide rails 3, and the two ends of the bidirectional screw rod 31 are respectively threadedly connected to the two groups of sliders 2 44. The bidirectional screw rod 31 is driven by a motor. When the bidirectional screw rod 31 rotates, it can make the two groups of sliders 2 44 move in opposite directions or towards each other at the same time, thereby driving the spray pipe 4 to move synchronously along the slide rail 3. This design allows the spray pipe 4 to automatically adjust its position according to the specific size of the photovoltaic panel to ensure the best cleaning coverage.

[0034] like Figure 4 As shown, a filter screen 6 is movably installed in the return water tank 1, and bottom plates 61 are fixedly provided on both sides of the filter screen 6. One side of the two bottom plates 61 is respectively fitted with the inner walls of the two sides of the return water tank 1. When the sewage enters the return water tank 1, it is filtered through the filter screen 6, and the filtered water can be clarified at the bottom of the return water tank 1.

[0035] like Figures 7 to 10 As shown, a filter assembly is rotatably installed in the water tank 9, and the water outlet end of the return water tank 1 is connected to the water inlet end of the filter assembly through a water diversion pipe 12. A water pump 13 is installed on the water diversion pipe 12. The water pump 13 can suck the clarified water in the return water tank 1 into the filter assembly through the water diversion pipe 12 for secondary filtration.

[0036] Specifically, the filter assembly includes a hollow tube 93 rotatably arranged in the water tank 9, a plurality of water outlet holes 95 are opened on the hollow tube 93, a hollow rotating rod 97 is rotatably arranged in the hollow tube 93, both ends of the hollow rotating rod 97 penetrate the two ends of the hollow tube 93, and the diameter of the middle part of the hollow rotating rod 97 is larger than the diameter of the two ends, so that the middle part of the hollow rotating rod 97 is protruding, and a plurality of groups of filter discs 971 are arranged in the middle part of the hollow rotating rod 97, and the filter discs 971 are installed in the opening of the hollow rotating rod 97. Since one end of the hollow rotating rod 97 is rotatably connected to the outlet pipe of the water diversion pipe 12, the water diversion pipe 12 can be made of a pipe made of hard material. Therefore, the clarified liquid in the return pool 1 can be sucked into the hollow rotating rod 97 by a water pump 13. The hollow rotating rod 97 rotates to throw the liquid out of the circular hole and filters it through the filter plate 971 to improve the cleanliness of the liquid. The liquid is then thrown out from the water outlet 95, so that the filtered liquid enters the water tank 9 for storage and standby.

[0037] like Figure 6 As shown, in order to reduce the entry of impurities when the clarified water in the return water tank 1 is pumped into the water tank 9, a cylinder 5 is installed in the middle of the two sets of slide rails 3. The piston end of the cylinder 5 passes through the bottom of the slide rail 3 and is connected to the extension rod 51. The lower end of the extension rod 51 is connected to the filter screen 6. Through the action of the cylinder 5, the filter screen 6 can be pushed to slowly descend to the bottom of the return water tank 1 to achieve effective separation of the clarified water and the impurities at the bottom. Since the slide grooves 63 are symmetrically opened on the upper side of the bottom plate 61, and the sealing plates 62 are slidably connected in the slide grooves 63, the two sealing plates 62 can be slid relative to each other so that the sealing plates 62 are fitted together to form a closed barrier to further prevent impurities from entering the clarified area. One side of the sealing plate 62 is opened with a pair of The notch 64 is called the notch 64, and the position of the notch 64 is consistent with the position of the piston end of the cylinder 5. When the two sealing plates 62 are fitted, the piston end of the cylinder 5 can be located in the two fitted notches 64, thereby improving the sealing effect of the two sealing plates 62 on the filter 6. At this time, the impurities at the bottom of the return water tank 1 can be separated from the clarified water on the top, and the bottom plate 61 and the filter 6 need to be moved to the lower side of the water inlet end of the water diversion pipe 12 without affecting the suction of the liquid on the upper side of the bottom plate 61. In order to make the filter 6 move more stably under the drive of the cylinder 5, a limiting groove can be opened on the inner wall of the return water tank 1 so that one side of the filter 6 slides in the limiting groove to improve the stability of the filter 6. Other movable limiting or stabilizing mechanisms can also be installed.

[0038] In addition, guide plates 8 are provided on both sides of the upper end of the return water tank 1. The guide plates 8 are inclined. When the bottom filter screen 6 is located at the upper end of the return water tank 1 for filtering, the guide plates 8 can block the bottom plate 61 (such as Figure 4 As shown), the sewage can accurately enter the filter screen 6.

[0039] In order to make the hollow tube 93 and the hollow rotating rod 97 rotate at the same time, a gear 2 972 is fixedly provided on the outside of the hollow rotating rod 97, a gear 1 96 is fixedly provided on the outside of the hollow tube 93, and a double-headed gear 98 is rotatably provided on the outside of the water tank 9. The double-headed gear 98 is a rotating shaft with two gears installed in sequence up and down. After the double-headed gear 98 is driven by a motor, the double-headed gear 98 engages with the gear 1 96 and the gear 2 972 respectively, so that the hollow tube 93 and the hollow rotating rod 97 rotate at the same time.

[0040] Considering that the weather in some areas is relatively cold, in order to prevent the water in the water tank 9 from freezing and affecting the water film spraying, multiple groups of ice-breaking blades 94 are arranged on the hollow tube 93 staggered with the water outlet 95. These ice-breaking blades 94 are designed to prevent the water in the water tank 9 from freezing due to low temperature. When the hollow tube 93 rotates, the ice-breaking blades 94 rotate accordingly and stir the water in the water tank 9. This continuous stirring can effectively prevent the water from being stationary and reduce the possibility of water freezing. Even if a small amount of ice crystals are formed, the movement of the ice-breaking blades 94 can break them up, ensuring the fluidity of the water body, thereby maintaining the normal operation of the system.

[0041] In addition, two groups of water inlets 92 are provided on the upper side of the water tank 9, which can be used to supplement the water source. This provides a backup water supply solution for the system, especially when a large amount of water is needed or the water volume in the return water tank 1 is insufficient. A cover plate 91 is hinged on the water tank 9 between the two groups of water inlets 92. After opening the cover plate 91, the operator can easily enter the water tank 9 for inspection, cleaning and maintenance. This design not only improves the convenience of daily maintenance, but also ensures the cleanliness and efficient operation of the system. A slope 7 inclined toward the drain pipe 11 is provided at the bottom of the return water tank 1. The slope 7 is provided at the bottom of the return water tank 1 and inclined toward the drain pipe 11 from all sides. This design helps to guide the water flow to the drain pipe 11, so that the water pump 13 can more effectively pump the water in the return water tank 1 to avoid residual water accumulating at the bottom of the return water tank 1 and affecting the working efficiency of the water pump 13.

[0042] An opening 973 is provided at the other end of the hollow rotating rod 97, and the opening 973 is sealed by a sealing column 974. When there are many impurities in the hollow rotating rod 97, water can be introduced into the hollow rotating rod 97, and the sealing column 974 can be removed to allow sewage to be discharged through the opening 973, thereby achieving internal self-cleaning and maintaining the cleanliness and working efficiency of the system. After cleaning, the sealing column 974 is reinserted to restore the sealing state.

[0043] Working process: according to the size of the photovoltaic, the two-way screw rod 31 is driven by the motor to make the two sets of sliders 44 move with the two sets of spray pipes 4 respectively. After the water pump 46 is started, the clean water in the water tank 9 is sucked into the spray pipe 4 and sprayed out through the spray head 41 to form a water film on the photovoltaic. The sewage enters the return water tank 1 through the gap of the electric roller 2. The guide plate 8 guides the sewage to the filter 6 for filtration. When the cleaning operation is completed, the sewage in the return water tank 1 is clarified. At this time, the two sealing plates 62 are slid to the fitting state, and the cylinder 5 is moved to The filter screen 6 is slowly pushed downward, and the bottom plate 61 and the sealing plate 62 are lowered to the lower end of the water inlet end of the water diversion pipe 12, and the impurities at the bottom of the return water tank 1 are separated from the clarified water on the upper side. The water pump 13 draws the water on the upper side of the return water tank 1 into the hollow rotating rod 97. Through the rotation of the hollow rotating rod 97, the water is filtered through the filter plate 971 and thrown into the hollow pipe 93, and then thrown out from the water outlet 95 on the hollow pipe 93 to the water tank 9 for storage. While the hollow pipe 93 is rotating, the ice-breaking blades 94 are prompted to stir the water in the water tank 9 to prevent the water from freezing.
