Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic panel cleaning, and in particular relates to a photovoltaic panel surface cleaning device. Background Art

[0002] With the widespread application of solar photovoltaic technology and the large-scale construction of distributed and centralized photovoltaic power stations, photovoltaic panels are prone to accumulate various types of dirt on their surfaces when they are operated in outdoor environments for a long time, such as dust, sand, moisture, bird droppings, etc. These pollutants will block or scatter sunlight, reducing the transmittance and absorption efficiency of light. Therefore, special photovoltaic panel surface cleaning equipment is needed for cleaning;

[0003] A photovoltaic panel surface cleaning device with the authorization announcement number CN 219211000 U includes a photovoltaic panel cleaning mechanism, through which two sets of connecting plates can be limitedly connected between the two ends of the scraping brush component and the moving component through a limit slot, a limit plug block, a positioning slot and a positioning plug plate structure, when the driving box rotates clockwise or counterclockwise under power, it can drive the hanging plate with a triangular scraping brush at the bottom to move back and forth on the top of the metal plate frame, and the reciprocating triangular scraping brush can also scrape and clean impurities such as bird droppings or soil attached to the surface of the photovoltaic panel, and through the gear lever and the compression spring structure, the cleaning component can perform adaptive elastic adjustment on the triangular scraping brush according to the use situation;

[0004] Although the surface of the photovoltaic panel can be cleaned, there are still some problems in daily use. The cleaning effect is limited if it is only relying on the triangular scraper brush for cleaning. Secondly, dust and impurities will adhere to the triangular scraper brush during use, which will make it impossible to effectively maintain the cleanliness of the triangular scraper brush itself, thereby reducing the cleaning efficiency. Manual intervention is required for cleaning, and dust will accumulate on the triangular scraper brush during non-cleaning operations, which means that the triangular scraper brush cannot be in a working state to be cleaned at all times.

It can also wash away the dust adsorbed on the cleaning brush roller to maintain its own cleanliness, thereby effectively solving the problem of reduced cleaning efficiency caused by the brush adsorbing sewage during the initial cleaning. No manual intervention is required for cleaning, and dust accumulation on the cleaning brush roller is prevented during non-cleaning operation periods, ensuring that the cleaning brush roller can be in a working state to be cleaned at any time.

[0006] In order to solve the above technical problems, the utility model provides a photovoltaic panel surface cleaning device, including a mounting frame and a cleaning mechanism arranged at the front end of the mounting frame, the cleaning mechanism including rectangular openings laterally symmetrically arranged at the left and right ends of the mounting frame, guide rods are arranged at the front ends between the upper and lower walls of the rectangular opening, a sliding shell is slidably connected between the two guide rods, a cleaning brush roller is rotatably connected to the middle part between the left and right walls of the sliding shell, a sealing component for sealing the sliding shell is also provided at the upper end of the mounting frame, the sealing component includes a limiting slide groove arranged on the step surface of the upper end of the mounting frame, a sealing plate shell is slidably connected in the limiting slide groove, the front surface of the sealing plate shell is matched with the rear end opening of the sliding shell, a spring evenly distributed laterally is arranged between the rear wall surface of the limiting slide groove and the front wall surface of the sealing plate shell, a spray component is also provided on the sliding shell, and a driving component for driving the sliding shell to move is also provided on the mounting frame.

[0008] The cleaning mechanism also includes a mounting hole arranged at the right end of the front surface of the sliding shell, a motor 1 is arranged in the mounting hole, a bevel gear 1 is arranged at the rear end of the output shaft of the motor 1, a bevel gear 2 is arranged at the right end of the outer arc surface of the cleaning brush roller, the bevel gear 2 is meshed and connected with the bevel gear 1, and the motor 1 is electrically connected to the external single-chip computer; the cleaning mechanism also includes a baffle plate arranged at the right end of the inner cavity of the sliding shell.

[0010] A scraper is provided at the rear end of the lower surface of the sliding shell.

[0011] The beneficial effects of the above technical solution of the utility model are as follows:

[0012] 1. When it is necessary to clean the surface of the photovoltaic panel, the relevant staff will synchronously control the operation of motor 1 through the single-chip machine, and at the same time control motor 2 to make reciprocating motion. The output shaft of motor 2 drives the rotating rod and the pulley 1 fixed at both ends to rotate together, and pulley 1 cooperates with pulley 2 through the transmission belt, so that the belt drives the sliding shell and its attached parts to slide back and forth along the guide rod steadily and orderly.

[0013] 2. When it is necessary to clean the surface of the photovoltaic panel, the relevant staff will accurately control the opening state of the solenoid valve on the water supply pipe through an external single-chip computer, thereby allowing the external water source to flow into the cleaning pipe and the flushing pipe through the solenoid valve. The water flowing out of the cleaning pipe is sprayed out through the cleaning nozzle. Following the moving trajectory of the sliding shell, the water jetted by the cleaning nozzle performs a preliminary cleaning of the photovoltaic panel, and the water entering the flushing pipe is sprayed out through the flushing nozzle to perform a deep flush on the area that has been cleaned by the cleaning brush roller to ensure a thorough cleaning effect. In addition, the flushing process can also wash away the dust adsorbed on the cleaning brush roller to maintain its own cleanliness, thereby effectively solving the problem of reduced cleaning efficiency caused by the brush adsorbing sewage during the initial cleaning, without the need for manual intervention in cleaning.

[0014] 3. When the surface of the photovoltaic panel is cleaned, the operator also controls the reset of each component through an external single-chip computer. The sliding shell will slide relative to the inclined surface in its moving path, thereby causing the sealing plate shell to shrink along the limiting slide groove under the action of the spring force. When the sliding shell is completely returned to its original position, with the help of the elastic restoring force of the spring itself, the sealing plate shell will move forward again until it fits tightly with the rear end opening of the sliding shell and maintains a seal, preventing dust from accumulating on the cleaning brush roller during non-cleaning operations, ensuring that the cleaning brush roller can be in a working state to be cleaned at any time.

[0023] like Figure 1-4 As shown, the spray assembly includes a cleaning pipe 400 arranged in the middle of the lower surface of the sliding shell 202, and cleaning nozzles 404 are provided in the cleaning openings uniformly arranged laterally on the lower side of the rear end of the outer arc surface of the cleaning pipe 400, and the cleaning nozzles 404 are inclined downward from front to back; the spray assembly also includes a flushing pipe 402 arranged on the lower side of the inner cavity of the sliding shell 202, and the left water inlet of the flushing pipe 402 penetrates the front surface of the sliding shell 202 and extends to the outside, and flushing nozzles 403 are provided in the flushing openings uniformly arranged laterally on the upper end of the outer arc surface of the flushing pipe 402.

[0024] like Figure 1-4 As shown, the driving component includes a through rotating hole arranged on the rear side of the upper end of the mounting frame 100, and the rectangular openings 200 are all connected to the through rotating hole. A rotating rod 500 is rotatably connected in the through rotating hole. The left and right ends of the outer arc surface of the rotating rod 500 are located in the rectangular opening 200 and are provided with pulley 1 501, and the lower end between the left and right walls of the rectangular opening 200 is rotatably connected with pulley 2 502, and the pulley 2 502 is respectively connected to the vertically adjacent pulley 1 501 through belts. The left and right ends of the rear surface of the sliding shell 202 are respectively fixedly connected to the adjacent belts on the same side, and a motor 2 503 is provided at the upper end of the right surface of the mounting frame 100. The left end of the output shaft of the motor 2 503 is fixedly connected to the right end of the rotating rod 500, and the motor 2 503 is electrically connected to the external single-chip computer.

[0025] The working principle of a photovoltaic panel surface cleaning device provided by the utility model is as follows: first, the operator will firmly install the mounting frame 100 and its supporting components on the photovoltaic panel to be cleaned. Next, the relevant staff will connect the water inlets of the cleaning pipe 400 and the flushing pipe 402 to the water outlet ports of the external water supply pipeline equipped with solenoid valves. When it is necessary to clean the surface of the photovoltaic panel, the relevant staff will accurately control the opening state of the solenoid valve on the water supply pipeline through the external single-chip microcomputer, thereby allowing the external water source to flow into the cleaning pipe 400 and the flushing pipe 402 through the solenoid valve. During this period, the external single-chip microcomputer will synchronously control the operation of the motor 204 and simultaneously The motor 2 503 is regulated to make reciprocating motion, and the output shaft of the motor 2 503 drives the rotating rod 500 and the pulley 1 501 fixed at both ends to rotate together, and the pulley 1 501 cooperates with the pulley 2 502 through the transmission belt, so that the belt drives the sliding shell 202 and its attached parts to slide back and forth along the guide rod 201 smoothly and orderly. At the same time, the output shaft of the motor 1 204 rotates to drive the bevel gear 1 205 to rotate synchronously. When the bevel gear 1 205 rotates, it is linked to the cleaning brush roller 203 to rotate synchronously through the bevel gear 2 206 meshing therewith. In this way, in the process of the sliding shell 202 moving back and forth on the surface of the photovoltaic panel, the cleaning brush roller 2 03 can effectively wipe off the dirt accumulated on the surface of the photovoltaic panel to ensure that the cleaning range is fully covered. At the same time, the water flowing out from the inside of the cleaning pipe 400 is sprayed out through the cleaning nozzle 404. Along the moving trajectory of the sliding shell 202, the water jetted by the cleaning nozzle 404 performs preliminary cleaning on the photovoltaic panel, and the water entering the flushing pipe 402 is sprayed out through the flushing nozzle 403 to perform deep flushing on the area cleaned by the cleaning brush roller 203 to ensure a thorough cleaning effect. In addition, the flushing process can also wash away the dust adsorbed on the cleaning brush roller 203 to maintain its own cleanliness, thereby effectively solving the problem of reduced cleaning efficiency caused by the brush adsorbing sewage during the initial cleaning. No manual intervention is required for cleaning. After the surface of the photovoltaic panel is cleaned, the operator also controls the reset of each component through an external single-chip computer. The sliding shell 202 will slide relative to the inclined surface in its moving path, thereby causing the sealing plate shell 301 to shrink along the limiting slide groove 300 under the action of the elastic force of the spring 302. When the sliding shell 202 is completely returned to its original position, with the help of the elastic restoring force of the spring 302 itself, the sealing plate shell 301 will move forward again until it is tightly fitted with the rear end opening of the sliding shell 202 and remains sealed, preventing dust from accumulating on the cleaning brush roller 203 during non-cleaning operations, ensuring that the cleaning brush roller 203 can be in a working state to be cleaned at any time.

[0026] like Figure 1-3 As shown, a scraper 600 is provided at the rear end of the lower surface of the sliding shell 202. The scraper 600 can effectively scrape off the sewage or dirt remaining on the surface of the photovoltaic panel, ensuring that the surface of the photovoltaic panel is dry and clean after cleaning.

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0028] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
