Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic power station technology, specifically a photovoltaic power station module cleaning and testing device. Background Technology

[0002] A photovoltaic power station is a facility that uses solar energy to generate electricity. It directly converts solar energy into electrical energy through photovoltaic modules and realizes the conversion, storage and transmission of electricity through supporting equipment. Its core function is to convert renewable solar energy resources into usable electrical energy. It is widely used in grid-connected power generation, off-grid power supply and other scenarios.

[0003] Cleaning and testing devices are frequently used when cleaning photovoltaic modules. While existing devices can perform basic cleaning and testing functions, they mostly rely on spraying water from nozzles to clean the modules. However, due to the strong adhesion of residues after exposure to sunlight, water rinsing alone is insufficient to thoroughly clean the modules. This necessitates manual secondary cleaning, which increases the workload for operators and reduces cleaning efficiency. Therefore, improvements are needed. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 5 As shown, this utility model provides a photovoltaic power station module cleaning and testing device, including a cleaning box 1. A support leg 2 is fixedly connected to the bottom of the inner cavity of the cleaning box 1, and a placement plate 3 is fixedly connected to the top of the support leg 2. A drive motor 4 is fixedly connected to the top of the left side of the cleaning box 1. A rotating shaft 5 is fixedly sleeved at the other end of the output shaft of the drive motor 4. A rotating rod 6 is fixedly sleeved on the outer surface of the rotating shaft 5. The outer surface of the rotating rod 6 is movably connected to the outer side of the cleaning box 1. A cylindrical block 7 is movably connected to the inner surface of the rotating rod 6. The outer surface of the cylindrical block 7 is movably connected to the inner wall of the left side of the cleaning box 1. A brush plate 8 is fixedly connected to the other end of the cylindrical block 7. The inner side of the brush plate 8 is movably connected to the outer side of the placement plate 3.

[0023] When the drive motor 4 is running, the rotating shaft 5 will drive the rotating rod 6 to rotate, which in turn will cause the cylindrical block 7 and the brush plate 8 to move downward along the inclined surface of the placement plate 3, thereby achieving the purpose of brushing the residue on the photovoltaic module.

[0024] Among them, the outer side of the placement plate 3 is fixedly connected with a limiting rod 9, and there are two limiting rods 9. The outer surfaces of the two limiting rods 9 are movably sleeved with the inner surface of the brush plate 8.

[0025] The design of the two limit rods 9 serves to limit the movement of the brush plate 8.

[0026] The right side of the cleaning tank 1 is fixedly connected to a drive motor 10. The other end of the output shaft of the drive motor 10 is fixedly sleeved with a double threaded screw 11. The left side of the double threaded screw 11 passes through the cleaning tank 1 and extends into the interior of the cleaning tank 1. The outer surface of the double threaded screw 11 is threadedly sleeved with a movable block 12. The outer surface of the movable block 12 is movably connected to the inner surface of the placement plate 3. The top of the movable block 12 is fixedly connected with a clamping block 13. There are two clamping blocks 13. The bottom of both clamping blocks 13 is movably connected to the top of the placement plate 3.

[0027] When the drive motor 10 is running, the double threaded screw 11 will rotate, causing the two movable blocks 12 to move towards each other, which in turn causes the two clamping blocks 13 to move towards each other to clamp and fix the photovoltaic module, thus preventing the photovoltaic module from moving during the cleaning process.

[0028] The bottom of the cleaning tank 1 is fixedly connected to a water collection tank 14, the top of the cleaning tank 1 is fixedly connected to a water pump 15, the back of the water pump 15 is fixedly connected to a suction pipe 16, the other end of the suction pipe 16 passes through the water collection tank 14 and extends into the interior of the water collection tank 14, a filter screen plate 17 is fixedly sleeved on the inner surface of the suction pipe 16, the top of the water pump 15 is fixedly connected to a drain pipe 18, the other end of the drain pipe 18 passes through the cleaning tank 1 and extends into the interior of the cleaning tank 1 and is fixedly sleeved with a nozzle 19, the top of the nozzle 19 is fixedly connected to the top of the inner cavity of the cleaning tank 1.

[0029] When the water pump 15 is running, the water source in the water collection tank 14 is filtered by the filter screen plate 17 and then drawn by the suction pipe 16. It is then transported to the inside of the nozzle 19 through the drain pipe 18 and sprayed out by the nozzle 19 to clean the photovoltaic module.

[0030] The bottom of the inner cavity of the cleaning tank 1 is provided with a drain hole 20, which is circular in appearance.

[0031] The design of the drain hole 20 allows the cleaned water to flow into the water collection tank 14 through the drain hole 20, thus achieving the purpose of water recycling.

[0032] A water inlet pipe 21 is fixedly connected to the top left side of the water collection tank 14, a valve 22 is fixedly installed at the bottom left side of the water collection tank 14, and a drain pipe 23 is fixedly connected to the left side of the valve 22.

[0033] The design of the water inlet pipe 21 makes it easy to add water to the inside of the water collection tank 14 through the water inlet pipe 21, and open the valve 22 to discharge the water inside the water collection tank 14 to the outside through the drain pipe 23.

[0034] The cleaning tank 1 has a hinged door 24 on its front, a handle 25 fixedly connected to the right side of the front of the door 24, and a testing device 26 fixedly installed inside the door 24.

[0035] The testing equipment 26 is designed to detect whether the photovoltaic modules are clean.

[0036] Working principle and usage process of this utility model:

[0037] When cleaning photovoltaic modules, the photovoltaic modules are first placed on the placement plate 3. Then, the drive motor 10 is started, which will cause the double threaded screw 11 to rotate, driving the two movable blocks 12 to move towards each other. This, in turn, causes the two clamping blocks 13 to move towards each other and clamp and fix the photovoltaic modules. Then, the water pump 15 is started. The water source is filtered through the filter screen plate 17 and then sucked up by the suction pipe 16. It is then transported to the inside of the nozzle 19 through the drain pipe 18 and sprayed out by the nozzle 19 to clean the photovoltaic modules. The cleaned water source then flows into the inside of the water collection tank 14 through the drain hole 20 to accumulate, thus achieving the purpose of water recycling and reducing water costs.

[0038] Because photovoltaic modules are exposed to the sun for a long time, the residue on them is difficult to clean with water. At this time, the drive motor 4 is started, which will cause the rotating shaft 5 to drive the rotating rod 6 to rotate. In turn, the rotating rod 6 rotates and drives the cylindrical block 7 and the brush plate 8 to move downward along the inclined surface of the placement plate 3, thereby achieving the purpose of brushing the residue on the photovoltaic modules and improving the cleaning efficiency. After the photovoltaic modules are cleaned, the detection device 26 is run to detect whether the photovoltaic modules are clean.
