Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module operation and maintenance inspection technology, and in particular to a photovoltaic module operation and maintenance inspection device. Background Technology

[0002] Photovoltaic modules, as the core component of a photovoltaic power generation system, are composed of several solar cells connected in series and parallel. If dirt or dust accumulates on the surface of a photovoltaic module over a long period of time, it can cause hot spots, which in turn affects the overall power generation performance and, in severe cases, can lead to equipment damage.

[0003] Operation and maintenance inspection of photovoltaic modules is a key link in ensuring the efficient and stable operation of photovoltaic power plants. By regularly conducting systematic inspections of module surface cleanliness, hot spot effect, microcracks and damage, junction box sealing and connection status, and combining intelligent detection equipment such as infrared thermal imaging and EL testers, potential problems such as dust accumulation and obstruction, module degradation, and line faults can be detected and addressed in a timely manner. This ensures that the power generation efficiency of the modules is maximized, while extending their service life, reducing the total life cycle operation and maintenance costs, and providing reliable support for the long-term profitability of the power plant.

[0004] In existing technologies, the daily cleaning and maintenance of photovoltaic modules mostly rely on manual labor. However, photovoltaic construction scenarios are gradually shifting towards complex terrains, including complex mountains, fish ponds, glass curtain walls, and other application scenarios, which undoubtedly increases the difficulty of daily maintenance and cleaning of photovoltaic modules. Summary of the Invention

[0005] Therefore, the technical problem to be solved by this utility model is to overcome the high difficulty of manual daily maintenance and cleaning of photovoltaic modules in the prior art, thereby providing a photovoltaic module operation and maintenance inspection device.

[0006] To address the aforementioned technical problems, this utility model provides a photovoltaic module operation and maintenance inspection device, comprising a drone body; multiple propellers are rotatably connected to the top of the drone body, and two legs are fixedly connected to the bottom of the drone body. A camera is mounted at one end of each leg, and the camera is rotatably connected to the drone body. A mounting slot is located on one side of the camera, at the bottom of the drone body. A cylinder is fixedly connected to the center of the mounting slot, and a fixing plate is fixedly connected to the bottom of the cylinder. An angle adjustment component is mounted on the bottom of the fixing plate, and a cleaning plate is fixedly connected to the bottom of the angle adjustment component. Multiple brushes are fixedly connected to the bottom of the cleaning plate. During operation, the drone body is manipulated to drive the propellers, lifting the legs off the ground and controlling the drone body to fly to the photovoltaic module area. The camera inspects the photovoltaic modules, identifying the locations of stains on the modules. The cylinder starts, causing the fixed plate to descend. The angle adjustment component adjusts the angle of the cleaning plate. The angle adjustment component consists of a servo motor with electronic and mechanical control parts, a position feedback potentiometer, and a control circuit board. Its principle is that the electronic control part adjusts the output angle and speed of the DC motor according to the controller's instructions, the mechanical part converts it into the displacement and angle change of the control surface, and the position feedback potentiometer feeds back the output angle voltage signal to the control circuit board to achieve closed-loop control, so that the cleaning plate can be parallel to the corresponding photovoltaic module, and the brush wipes and cleans the photovoltaic module. By setting up the drone body, propellers, legs, camera, and mounting slot to inspect the photovoltaic module, and then carrying the cylinder, fixed plate, angle adjustment component, cleaning plate, and brush to clean the photovoltaic module, the manual inspection and maintenance operation is reduced. Multiple drone bodies can also operate simultaneously, improving the efficiency of photovoltaic module maintenance and inspection.

[0007] In one embodiment of this utility model, an air pump is provided on one side of the angle adjustment component. The air pump is fixedly connected to the cleaning plate. A through pipe is connected to one side of the air pump, and the through pipe is connected to the cleaning plate. An air outlet is provided on one side of the brush, and the cleaning plate is connected to the air outlet. During operation, dust and impurities that are easily cleaned on the photovoltaic module can be cleaned without the brush. The air pump guides the airflow through the through pipe into the air outlet. An air pipe in the cleaning plate is connected to the through pipe and the air outlet. The airflow is emitted from the air outlet and acts on the photovoltaic module. Driven by the drone body, the dust adhering to the photovoltaic module can be quickly blown away and cleaned. By setting up the air pump, through pipe, and air outlet, a large-area preliminary cleaning of the photovoltaic module can be performed during the flight of the drone body, reducing the need for brush to wipe each photovoltaic module when the dust is easy to clean, which leads to a decrease in cleaning efficiency.

[0008] In one embodiment of this utility model, a mounting bracket is provided on one side of the cylinder, and the mounting bracket is snapped into the mounting groove. A stop block is hinged to one side of the mounting bracket, and the stop block is snapped into the mounting groove. A water storage bottle is provided on one side of the stop block, and the water storage bottle is snapped into the mounting groove. A water inlet is connected to one side of the water storage bottle, and a first conduit is provided on one side of the water inlet. The first conduit is connected to the water storage bottle, and a flexible hose is connected to one end of the first conduit. The flexible hose is spiral-shaped, and one end of the flexible hose is connected to a second conduit. One end of the second conduit is connected to a cleaning plate. A water outlet is provided on one side of the air outlet, and the water outlet is connected to the cleaning plate. During operation, a water pipe in the cleaning plate connects the second conduit to the water outlet. For stains and dirt that are difficult to clean with a brush, the water pump in the water storage bottle is started, and the cleaning liquid in the water storage bottle is introduced into the first conduit. After being conducted through the hose and the second conduit, it is discharged from the water outlet and acts on the photovoltaic module to rinse the stains. Then, the stains are repeatedly wiped by the brush, and finally, the gas discharged through the air outlet dries them, thus thoroughly cleaning the substances that are difficult to clean.

[0009] In one embodiment of this utility model, a high-pressure nozzle is provided at the bottom of the water outlet. The high-pressure nozzle is connected to the water outlet. When working, the high-pressure nozzle is connected to the water outlet. The high-pressure nozzle can be pressurized by the cleaning liquid to form a strong impact force. This impact force can directly peel off stubborn stains on the surface of the photovoltaic panel, such as bird droppings, tree sap, oil stains, etc.

[0010] In one embodiment of this utility model, an elastic rope is sleeved in the middle of the hose. One end of the elastic rope is fixedly connected to the first conduit, and the other end of the elastic rope is fixedly connected to the second conduit. When working, when the cylinder drives the cleaning plate to descend, the second conduit will follow. The hose is soft and has a certain elasticity, so it can be stretched. The elastic rope restricts and supports the hose, reducing the possibility of the hose falling off and causing the drone to drag the long hose and scrape and collide with the photovoltaic module during flight.

[0011] In one embodiment of this utility model, a filter is connected to one end of the first conduit. The filter is fixedly connected to the water storage bottle. When in operation, the filter filters the liquid coming out of the water storage bottle to reduce the accumulation of impurities that could cause blockage of the water outlet.

[0012] In one embodiment of this utility model, a sealing ring is provided on the outer side of the second conduit. The sealing ring is fixedly connected to the cleaning plate. During operation, the sealing ring fills the connection gap between the second conduit and the cleaning plate to reduce liquid leakage.

[0013] In one embodiment of this utility model, a lens cover is provided on the outside of the camera. The lens cover is snapped into the drone body. During operation, the lens cover protects the camera and reduces the possibility of the camera lens being scratched.

[0014] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial effects:

[0015] The photovoltaic module operation and maintenance inspection device described in this utility model inspects photovoltaic modules by setting up a drone body, propeller, legs, camera, and mounting slot. Then, it carries a cylinder, fixing plate, angle adjustment component, cleaning plate, and brush to clean the photovoltaic modules, reducing manual inspection and maintenance operations. Multiple drone bodies can also operate simultaneously, improving the efficiency of photovoltaic module operation and maintenance inspection.

[0016] The photovoltaic module operation and maintenance inspection device described in this utility model, by setting up an air pump, a through pipe, and an air outlet, can perform large-area preliminary cleaning of photovoltaic modules during the flight of the drone itself. This reduces the need for brushing each photovoltaic module individually when dust is easy to clean, which leads to reduced cleaning efficiency. Attached Figure Description

For stains and dirt that are difficult to wipe clean by the brush 19, the water pump in the water storage bottle 32 starts and introduces the cleaning liquid in the water storage bottle 32 into the first conduit 34. After being conducted through the hose 35 and the second conduit 36, it is discharged from the water outlet 37 and acts on the photovoltaic module to rinse the stains.

The elastic rope 5 restricts and supports the hose 35, reducing the possibility of the hose 35 falling off and causing the drone body 1 to drag the long hose 35 and scrape and collide with the photovoltaic module during flight.

[0031] Reference Figures 1 to 3 As shown, one end of the first conduit 34 is connected to a filter 6, which is fixedly connected to the water storage bottle 32.

[0034] This utility model discloses a photovoltaic module maintenance and inspection device. The device controls a drone body 1 to drive the propeller 11, causing the support legs 12 to detach from the ground. The drone body 1 is then controlled to fly to the photovoltaic module area. The camera 13 inspects the photovoltaic modules. Upon identifying a stain on the photovoltaic module, the cylinder 15 is activated, causing the fixed plate 16 to descend. An angle adjustment component 17 adjusts the angle of the cleaning plate 18. The angle adjustment component 17 consists of a servo motor with electronic and mechanical control components, a position feedback potentiometer, and a control circuit board. Its principle is that the electronic control component adjusts the output angle and speed of the DC motor according to the controller's instructions, while the mechanical component converts this into control surface displacement and angle change. The position feedback potentiometer feeds back the output angle voltage signal to the control circuit board, achieving closed-loop control so that the cleaning plate 18 is level with the corresponding photovoltaic module. The brush 19 wipes and cleans the photovoltaic modules; by setting up the drone body 1, propeller 11, legs 12, camera 13, and mounting slot 14, the photovoltaic modules are inspected, and then the cylinder 15, fixing plate 16, angle adjustment component 17, cleaning plate 18, and brush 19 are carried to clean the photovoltaic modules, reducing manual inspection and maintenance operations.

This reduces the need for brushes 19 to wipe each easily cleanable dust spot on the photovoltaic modules, which would otherwise reduce cleaning efficiency. A water pipe in the cleaning plate 18 connects the second conduit 36 ​​to the water outlet 37. For stains and dirt that are difficult to clean with the brush 19, the water pump in the water tank 32, once started, introduces the cleaning solution into the first conduit 34. This solution is then conducted through the hose 35 and the second conduit 36, and finally discharged from the water outlet 37. This solution acts on the photovoltaic modules to rinse away the stains. The stains are then repeatedly wiped by the brush 19, and finally dried by the air discharged from the air outlet 22. This provides a comprehensive cleaning for difficult-to-clean substances. A high-pressure nozzle 4 is connected to the water outlet 37, and high-pressure spray... The head 4 can be pressurized with cleaning fluid to generate a powerful impact force. This impact force can directly peel off stubborn stains such as bird droppings, tree sap, and oil stains from the surface of the photovoltaic panel. When the cylinder 15 drives the cleaning plate 18 to descend, the second conduit 36 ​​will follow. The hose 35 is soft and has a certain degree of elasticity, allowing it to be stretched. The elastic rope 5 restricts and supports the hose 35, reducing the possibility of the hose 35 scattering and causing the drone body 1 to drag the long hose 35 and scrape or collide with the photovoltaic module during flight. The filter 6 filters the liquid coming out of the water storage bottle 32, reducing the accumulation of impurities that could clog the water outlet 37. The sealing ring 7 fills the connection gap between the second conduit 36 ​​and the cleaning plate 18, reducing liquid leakage.
