When the cleaning component moves to different positions of the photovoltaic panel body, according to the actual cleaning requirements, by controlling the opening and closing of the solenoid valve, the spraying range and intensity of the nozzle can be flexibly adjusted, avoiding waste of water resources and improving the cleaning effect at the same time;

[0004] 2. In the cleaning device for photovoltaic power station components and its usage method, the baffle can block larger sundries, such as fallen leaves, garbage, etc., from entering the collection box, preventing these sundries from blocking the filtering structure or water delivery pipe inside the collection box, facilitating its normal use, and blocking the sundries on the top of the collection box is also convenient for subsequent collection, improving its practicability. Through the design of the collection box, water delivery pipe, and water storage tank, the filtered water source can enter the water storage tank, facilitating subsequent extraction and use;

[0005] 2. In the cleaning device for photovoltaic power station components and its usage method, the flexible connecting pipe two has good flexibility.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Embodiment 1: As Figure 1-12As shown in the figure, a cleaning device for photovoltaic power station components provided by the present invention includes a chassis 1 and a photovoltaic panel body 2.

At one end of the limit frame 5, a driving motor 6 is fixedly installed. On the output shaft of the driving motor 6, a driving rod 7 is fixedly installed. On the outer surface of the driving rod 7, a cleaning assembly 8 located at one end of the photovoltaic panel body 2 and slidably connected to the limit frame 5 is provided. On one side of the chassis 1 close to the cleaning assembly 8, a support rod 9 and a water storage tank 10 are fixedly installed. On one side of the water storage tank 10, a water delivery pipe 12 is provided. At the other end of the water delivery pipe 12 away from the water storage tank 10, a collection assembly 11 is provided;

[0021] The cleaning assembly 8 includes a moving block 801 slidably connected inside the limit frame 5. At the other end of one side of the moving block 801 away from the limit frame 5, a moving frame 804 is fixedly installed. On one side of the moving frame 804 close to the photovoltaic panel body 2, a fixed frame 805 is fixedly installed. At one end of the fixed frame 805 close to the photovoltaic panel body 2, a cleaning cloth 806 is provided. At the other end of the fixed frame 805 away from the cleaning cloth 806, a booster pump 807 is fixedly installed. In sequence at the output end of the booster pump 807, a first connecting pipe 808, a three-way valve 809 and a third connecting pipe 811 are provided. On one side of the third connecting pipe 811, a water outlet pipe 812 and a nozzle 814 are provided;

[0022] The collection assembly 11 includes a mounting frame 1101, and inside the mounting frame 1101, a collection box 1102 is fixedly installed.

[0023] Specifically, fixed columns 802 are fixedly installed on both the upper and lower sides of the moving block 801. At the outer edge of the fixed columns 802 away from the center line, pulleys 803 are rotatably installed. The pulleys 803 are slidably connected to the limit frame 5. The advantage is that when the driving motor 6 drives the driving rod 7 to rotate, the moving block 801 connected to the driving rod 7 moves inside the limit frame 5. The pulleys 803 rotatably installed on the fixed columns 802 convert the sliding friction between the moving block 801 and the limit frame 5 into rolling friction, greatly reducing the resistance during the movement, enabling the cleaning assembly 8 to move more smoothly and efficiently along the limit frame 5, reducing the energy consumption of the driving motor 6, and improving the operation stability and efficiency of the cleaning device.

[0024] Specifically, the fixed columns 802 are adapted to the pulleys 803. There are two identical sets of the fixed columns 802 and the pulleys 803. Each set has a plurality of identical fixed columns 802 and pulleys 803 which are equally spaced. The two sets of fixed columns 802 and pulleys 803 are symmetrically distributed about the center line of the photovoltaic panel body 2. The advantage is that the two symmetrically distributed sets of fixed columns 802 and pulleys 803 can provide uniform and stable supporting forces for the moving block 801 during its movement. The multiple equally spaced pulleys 803 further ensure that the moving block 801 will not tilt or shift when moving within the limit frame 5, ensuring that the cleaning assembly 8 always remains perpendicular and parallel to the photovoltaic panel body 2, so that the cleaning cloth 806 can uniformly clean the surface of the photovoltaic panel body 2, improving the consistency and reliability of the cleaning effect.

[0025] Embodiment 2: As Figure 2-12 shown, as an improvement over the previous embodiment.

[0026] Specifically, the first connecting pipe 808, the three-way valve 809, the third connecting pipe 811, the water outlet pipe 812 and the nozzle 814 are interconnected. An electromagnetic valve 813 is provided at the connection between the water outlet pipe 812 and the nozzle 814. The advantage is that the booster pump 807 transports water through the first connecting pipe 808, the three-way valve 809 and the third connecting pipe 811 to the water outlet pipe 812, and finally sprays it out through the nozzle 814, which is convenient for controlling each nozzle 814. When the cleaning assembly 8 moves to different positions of the photovoltaic panel body 2, the spraying range and intensity of the nozzle 814 can be flexibly adjusted by controlling the switch of the electromagnetic valve 813 according to the actual cleaning requirements, avoiding waste of water resources and improving the cleaning effect at the same time.

[0027] Specifically, the water outlet pipes 812, the electromagnetic valves 813 and the nozzles 814 are in one-to-one correspondence. There are a plurality of identical water outlet pipes 812, electromagnetic valves 813 and nozzles 814. The multiple water outlet pipes 812, electromagnetic valves 813 and nozzles 814 are equally spaced. The advantage is that the multiple equally spaced nozzles 814 can spray water on the surface of the photovoltaic panel body 2 comprehensively and uniformly, improving its cleaning range. And after the spraying is completed, it is convenient for the cleaning cloth 806 to wipe off the dust on the surface of the photovoltaic panel body 2, thereby improving its practicability. And according to the dirt degree of different areas of the photovoltaic panel body 2, the spraying of the nozzles 814 can be controlled specifically, further improving the cleaning efficiency and water resource utilization rate.

[0028] Specifically, the collection box 1102 is successively provided with a first filter box 1103, a second filter box 1104, and a third filter box 1105 from top to bottom. The first filter box 1103, the second filter box 1104, and the third filter box 1105 are all located inside the collection box 1102. The advantage is that through the design of the first filter box 1103, the second filter box 1104, and the third filter box 1105, when it rains, rainwater can be collected. Subsequently, filter media are placed inside the first filter box 1103, the second filter box 1104, and the third filter box 1105, and then stored in the collection box 1102, which is convenient for subsequent cleaning and can save water resources and improve practicality.

[0029] Embodiment 3: As Figure 2-12 shown, as an improvement over the previous embodiment.

[0030] Specifically, a baffle 1106 with a plurality of equally spaced through holes is provided at the top of the collection box 1102. The collection box 1102, the water delivery pipe 12, and the water storage tank 10 are interconnected. The advantage is that the baffle 1106 can block larger sundries, such as fallen leaves and garbage, from entering the collection box 1102, preventing these sundries from clogging the filter structure inside the collection box 1102 or the water delivery pipe 12, facilitating its normal use. And blocking the sundries at the top of the collection box 1102 is also convenient for subsequent collection, improving its practicality. Through the design of the collection box 1102, the water delivery pipe 12, and the water storage tank 10, the filtered water source can enter the water storage tank 10, facilitating subsequent extraction and use.

[0031] Specifically, support frames 3 are fixedly installed at both ends of the chassis 1 away from the center line. A reinforcing block 4 is fixedly installed at the top of the support frame 3. The other end of the reinforcing block 4 away from the support frame 3 is adapted to the limit frame 5. The advantage is that the support frame 3 provides additional support for the chassis 1, enhancing the stability of the entire cleaning device. The reinforcing block 4 is adapted to the limit frame 5, further strengthening the connection between the limit frame 5 and the chassis 1. During the movement of the cleaning assembly 8, it can effectively prevent the limit frame 5 from shaking or displacing, ensuring that the cleaning assembly 8 moves stably along the predetermined trajectory, guaranteeing the smooth progress of the cleaning work, and at the same time extending the service life of the cleaning device.

[0032] Specifically, the other end of the three-way valve 809 away from the connecting pipe one 808 and the connecting pipe three 811 is provided with a connecting pipe two 810. The connecting pipe two 810 is a flexible connecting pipe. The advantage is that the flexible connecting pipe two 810 has good flexibility. When the cleaning assembly 8 moves, the connecting pipe two 810 can bend and deform accordingly without affecting the water delivery, avoiding the breakage or damage of the connecting pipe caused by the movement of the cleaning assembly 8.

[0033] Working principle: When in use, first install the cleaning component 8 on the top of the limit frame 5 and the photovoltaic panel body 2, and install the drive motor 6 and the drive rod 7 and connect them to the cleaning component 8. Turn on the drive motor 6, and its output shaft drives the drive rod 7 to rotate, causing the connected moving block 801 to move within the limit frame 5. At the same time, the pulley 803 on the moving block 801 converts sliding friction into rolling friction to ensure the efficient and stable movement of the cleaning component 8. When the cleaning component 8 moves, the water in the water storage tank 10 can be pressurized by the booster pump 807 and transported through the first connecting pipe 808, the three-way valve 809, and the third connecting pipe 811 to a plurality of water outlet pipes 812 distributed at equal intervals, and finally sprayed out by the nozzles 814. During the water spraying process, according to the dirt degree of different areas of the photovoltaic panel body 2, the solenoid valve 813 can be controlled to flexibly adjust the water spraying range and intensity of the nozzles 814. During the movement of the cleaning component 8, the moving frame 804 drives the fixed frame 805 and the cleaning cloth 806 forward. After the nozzles 814 spray water to moisten the surface of the photovoltaic panel body 2, the cleaning cloth 806 immediately wipes off the dirt to complete the cleaning work. When it rains, the rainwater flows into the collection box 1102 through the mounting frame 1101 of the collection component 11. The baffle 1106 blocks sundries, and the first, second, and third filter boxes in the collection box 1102 filter the rainwater step by step to remove impurities. The filtered rainwater flows into the water storage tank 10 through the water delivery pipe 12 for subsequent cleaning use, realizing the recycling of water resources.

Background technique With the continuous growth of the global demand for clean energy, photovoltaic power stations, as an important way of renewable energy generation, have been widely applied and developed. Photovoltaic power stations convert solar energy into electrical energy and have many advantages such as environmental protection and sustainability. Photovoltaic power stations often use solar photovoltaic panels to collect energy. Solar photovoltaic panels are devices used to convert light energy into electrical energy. Therefore, their working environment is outdoors. Due to the complex outdoor environment, it is very easy for dust, debris, etc. to accumulate on the surface of solar photovoltaic panels. And the photoelectric conversion efficiency of solar photovoltaic panels is related to the light intensity. Therefore, dust, debris, etc. on the surface of solar photovoltaic panels will reduce the light intensity and lead to a decrease in their power generation efficiency. So, in order to avoid the above problems, a cleaning device is often needed to clean them, thereby improving their power generation efficiency. Chinese Invention Patent Publication No.: CN111389774B, discloses: A cleaning device for solar photovoltaic panels and its use method.

However, the cleaning device for solar photovoltaic panels and its use method are not convenient for spraying water during the process of translational cleaning, which is likely to cause stains, etc. to adhere to the surface of the solar panel, not convenient for cleaning, resulting in low cleaning efficiency. At the same time, it is not convenient to collect rainwater and not convenient to realize the recycling of water resources, resulting in poor practicability.

Preferably, support frames are fixedly installed at both ends of the chassis away from the center line, and a reinforcing block is fixedly installed at the top of the support frame, and the other end of the reinforcing block away from the support frame is adapted to the limit frame. Through the above technical solution, the support frame provides additional support for the chassis, enhancing the stability of the entire cleaning device. The reinforcing block is adapted to the limit frame, further strengthening the connection between the limit frame and the chassis. During the movement of the cleaning component, it can effectively prevent the limit frame from shaking or displacing, ensuring that the cleaning component moves stably along the predetermined trajectory, guaranteeing the smooth progress of the cleaning work, and at the same time extending the service life of the cleaning device. Preferably, a second connecting pipe is provided at the other end of the three-way valve away from the first connecting pipe and the third connecting pipe, and the second connecting pipe is a flexible connecting pipe. Through the above technical solution, the flexible connecting pipe two has good flexibility. When the cleaning component moves, the connecting pipe two can bend and deform accordingly without affecting the water delivery, and can avoid the breakage or damage of the connecting pipe caused by the movement of the cleaning component. The present invention also provides a use method of a cleaning device for photovoltaic power station components, including the following steps: S1: First, install the cleaning component on the top of the limit frame and the photovoltaic panel body, and install the driving motor and the driving rod and connect them to the cleaning component. S2: Start the driving motor, and its output shaft drives the driving rod to rotate, so that the connected moving block moves in the limit frame. At the same time, the pulley on the moving block converts sliding friction into rolling friction, ensuring the efficient and stable movement of the cleaning component. S3: When the cleaning component moves, the water in the water storage tank can be pressurized by a booster pump, and is delivered through the first connecting pipe, the three-way valve and the third connecting pipe to a plurality of equally spaced water outlet pipes, and finally sprayed out by the nozzles. S4: During the water spraying process, according to the dirt degree of different areas of the photovoltaic panel body, the spraying range and intensity of the nozzles can be flexibly adjusted by controlling the solenoid valve. S5: During the movement of the cleaning component, the moving frame drives the fixed frame and the cleaning cloth to move forward. After the nozzles spray water to wet the surface of the photovoltaic panel body, the cleaning cloth immediately wipes off the dirt, completing the cleaning work. S6: During rainfall, rainwater flows into the collection tank through the mounting frame of the collection component. The baffle blocks debris, and the first, second, and third-stage filter boxes in the collection tank filter the rainwater step by step to remove impurities. The filtered rainwater flows into the storage tank through the water delivery pipe for subsequent cleaning use, realizing the recycling of water resources.
