A surface cleaning device for photovoltaic solar panels

Abstract

This utility model discloses a surface cleaning device for photovoltaic solar panels, relating to the field of solar panel processing. It includes a housing with a conveyor belt at the bottom and a rinsing mechanism inside. A hydraulic cylinder is fixed to the top of the housing, and a lifting seat is fixed to the output end of the hydraulic cylinder. A scrubbing mechanism is located at the bottom of the lifting seat, and a squeezing mechanism, including an L-shaped plate, is located on one side of the lifting seat. The lifting seat moves a sponge upwards. When the sponge is higher than the squeezing trough, the lifting seat continues to move upwards, causing a wedge block to enter the wedge groove. The L-shaped plate moves closer to the lifting seat, and the squeezing trough moves below the sponge. At this point, the lifting seat continues to move upwards, moving the wedge block upwards. The wedge block, through the L-shaped plate, moves the squeezing trough upwards, allowing the sponge to enter the squeezing trough and be squeezed to expel wastewater, thus preventing the wastewater in the sponge from affecting the subsequent cleaning effect of the solar panels.

Description

Technical Field

[0001] This utility model relates to the field of solar panel processing, and in particular to a surface cleaning device for photovoltaic solar panels. Background Technology

[0002] A photovoltaic solar panel is an assembly consisting of several solar cells assembled on a single plate in a specific manner. It is the core component of a solar power generation system, utilizing the photoelectric effect to convert the heat energy generated by solar radiation into electrical energy. The raw materials are silicon, gallium arsenide, or cadmium sulfide, etc. The processing of photovoltaic solar panels generates stains and dust, so the solar panels need to be cleaned before packaging.

[0003] For example, patent document CN222602363U discloses an automatic surface cleaning device for photovoltaic solar panel production. It uses a conveyor belt to transport solar panels, and the cleaning device sprays water to clean the solar panels. It also uses a sponge to wipe the solar panels by reciprocating movement. However, the sponge absorbs wastewater after use. If the wastewater in the sponge is not squeezed out, the wastewater will flow back onto the solar panel when the sponge wipes the next one. The longer the sponge is used, the dirtier it becomes, which affects the cleaning effect of subsequent solar panels. Utility Model Content

[0004] The purpose of this invention is to provide a surface cleaning device for photovoltaic solar panels in order to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A surface cleaning device for photovoltaic solar panels includes a housing with a conveyor belt at the bottom and a rinsing mechanism inside. A hydraulic cylinder is fixed to the top of the housing, and a lifting seat is fixed to the output end of the hydraulic cylinder. A scrubbing mechanism is located at the bottom of the lifting seat, and a squeezing mechanism is located on one side of the lifting seat. The squeezing mechanism includes an L-shaped plate with a wedge block fixed to the top. A wedge groove matching the wedge block is provided on the side of the lifting seat near the L-shaped plate. A squeezing trough is fixed to the bottom of the L-shaped plate and is located below the lifting seat. A hose is fixed to one end of the squeezing trough. A baffle is fixed to the inner wall of the housing and is located above the scrubbing mechanism. A pressure mechanism is provided on the side of the L-shaped plate away from the lifting seat.

[0007] Preferably, the pressure mechanism includes a slide plate, which is slidably connected to the inner wall of the housing. Multiple sleeves are fixed on the side of the slide plate near the L-shaped plate. A pressure rod is slidably connected inside the sleeve. One end of the pressure rod is fixedly connected to the L-shaped plate, and a second spring is fixedly connected to the other end of the pressure rod. One end of the second spring is fixedly connected to the sleeve.

[0008] Preferably, a guide rod is slidably connected inside the lifting seat, a first spring is fixed at the top of the guide rod, the top of the first spring is fixedly connected to the lifting seat, and the wiping mechanism is set at the bottom of the guide rod.

[0009] Preferably, the scrubbing mechanism includes a mounting plate, which is fixed to the bottom of the guide rod. A baffle is located above the mounting plate. A movable plate is provided at the bottom of the mounting plate. A sponge is fixed at the bottom of the movable plate. Two sliders are fixed at the top of the movable plate. The sliders are slidably connected to the bottom of the mounting plate. A motor is fixed at the top of the mounting plate. A cam is fixed to the output shaft of the motor. The cam is located between the two sliders.

[0010] Preferably, the wedge block is rotatably connected to a roller on the side near the lifting seat.

[0011] Preferably, the rinsing mechanism includes a water pump, which is fixed at the rear end of the housing. A water pipe is fixed to the outlet end of the water pump, and multiple nozzles are fixed to the bottom of the water pipe. The water pump is connected to an external water source.

[0012] The beneficial effects are as follows: the lifting seat moves the sponge upward. When the sponge is higher than the squeezing tank, the lifting seat continues to move upward, causing the wedge block to enter the wedge groove. The L-shaped plate will approach the lifting seat, and the squeezing tank will move below the sponge. At this time, the lifting seat continues to move upward, which will move the wedge block upward. The wedge block, through the L-shaped plate, moves the squeezing tank upward, allowing the sponge to enter the squeezing tank and be squeezed to discharge the wastewater, thereby preventing the wastewater in the sponge from affecting the subsequent cleaning effect of the solar panel.

[0027] The present invention will be further described below with reference to the accompanying drawings:

[0028] like Figures 1-9 As shown, a surface cleaning device for photovoltaic solar panels includes a housing 1. A conveyor belt 2 is installed at the bottom of the housing 1. A rinsing mechanism 3 is installed inside the housing 1. A hydraulic cylinder 4 is fixed to the top of the housing 1 by screws. A lifting seat 5 is fixed to the output end of the hydraulic cylinder 4. A scrubbing mechanism 8 is installed at the bottom of the lifting seat 5. A squeezing mechanism 6 is installed on the left side of the lifting seat 5. The squeezing mechanism 6 includes an L-shaped plate 601. A wedge block 602 is fixed to the top of the L-shaped plate 601 by screws. A wedge groove 501, adapted to the wedge block 602, is provided on the side of the lifting seat 5 near the L-shaped plate 601. When the wedge block 602 mates with the wedge groove 501... When not in a coordinated state, the wedge block 602 abuts against the left side of the lifting seat 5. The bottom end of the L-shaped plate 601 is fixed with a squeezing trough 603, which is located below the lifting seat 5. One end of the squeezing trough 603 is fixed with a hose 604, which is used to discharge the sewage in the squeezing trough 603. A baffle 101 is fixed on the inner wall of the tank 1, which is located above the scrubbing mechanism 8. The baffle 101 is used to limit the height of the scrubbing mechanism 8. A pressure mechanism 7 is provided on the side of the L-shaped plate 601 away from the lifting seat 5. The pressure mechanism 7 can make the wedge block 602 press against the left side of the lifting seat 5.

[0029] The pressure mechanism 7 includes a slide plate 701, which is slidably connected to the inner wall of the housing 1. Multiple sleeves 702 are fixed to the side of the slide plate 701 near the L-shaped plate 601. A pressure rod 703 is slidably connected inside the sleeve 702. One end of the pressure rod 703 is fixedly connected to the L-shaped plate 601, and the other end of the pressure rod 703 is fixedly connected to a second spring 704. One end of the second spring 704 is fixedly connected to the sleeve 702. The second spring 704 is in a compressed state and applies a pushing force to the pressure rod 703, causing the pressure rod 703 to apply a pushing force to the L-shaped plate 601, thereby causing the wedge block 602 to stick to the left side of the lifting seat 5. A roller 605 is rotatably connected to the side of the wedge block 602 near the lifting seat 5. By setting the roller 605, the friction between the wedge block 602 and the lifting seat 5 can be reduced.

[0030] The lifting seat 5 has a guide rod 502 slidably connected inside. A first spring 503 is fixed at the top of the guide rod 502. The first spring 503 is in a stretched state, that is, the first spring 503 applies an upward pulling force to the guide rod 502. The top of the first spring 503 is fixedly connected to the lifting seat 5. The scrubbing mechanism 8 is set at the bottom of the guide rod 502.

[0031] The scrubbing mechanism 8 includes a mounting plate 801, which is fixed to the bottom of the guide rod 502. A baffle 101 is located above the mounting plate 801. A movable plate 802 is provided at the bottom of the mounting plate 801. A sponge 803 is fixed at the bottom of the movable plate 802. Two sliders 804 are fixed at the top of the movable plate 802. The sliders 804 are slidably connected to the bottom of the mounting plate 801, so that the sponge 803 can move relative to the mounting plate 801, that is, the sponge 803 can move back and forth. A motor 805 is fixed to the top of the mounting plate 801 by screws. A cam 806 is fixed to the output shaft of the motor 805. The cam 806 is located between the two sliders 804. When the cam 806 rotates, it will alternately push the two sliders 804, thereby causing the sliders 804 to drive the movable plate 802 to move back and forth.

[0032] The rinsing mechanism 3 includes a water pump 301, which is fixed at the rear end of the housing 1. A water pipe 302 is fixed at the outlet end of the water pump 301, and multiple nozzles 303 are fixed at the bottom of the water pipe 302. The water pump 301 is connected to a water source.

[0033] Working principle: In use, the solar panel is placed at the left end of the conveyor belt 2. The conveyor belt 2 feeds the solar panel to the right into the housing 1. The solar panel first passes under the rinsing mechanism 3. The water pump 301 draws water and sends it into the water pipe 302. The nozzle 303 sprays water to rinse the solar panel. Then the solar panel moves to the under the sponge 803. The motor 805 drives the cam 806 to rotate. The cam 806 alternately pushes the front and rear sliders 804, causing the sliders 804 to drive the movable plate 802 to move back and forth. The movable plate 802 drives the sponge 803 to move back and forth, thus wiping the solar panel. After cleaning, the solar panel can be sent out from the right side of the housing 1. The pressure cylinder 4 drives the lifting seat 5 to move upward. Under the tension of the first spring 503, the guide rod 502 moves upward with the lifting seat 5. At the same time, the guide rod 502 drives the mounting plate 801 to move upward. When the mounting plate 801 abuts against the bottom of the baffle 101, the mounting plate 801 can no longer move upward, and the guide rod 502 can no longer move upward. At this time, the sponge 803 is higher than the squeezing tank body 603, and then the lifting seat 5 continues to move upward. The first spring 503 is stretched until the wedge groove 501 moves upward to the wedge block 602. Because the second spring 704 applies a leftward pushing force to the pressure rod 703, the L-shaped plate 601 and the wedge block 602 tend to move to the left. As the lifting seat 5 moves upward... As the wedge block 602 gradually and completely enters the wedge groove 501, the L-shaped plate 601 also drives the squeezing trough 603 to move to the left a certain distance, causing the squeezing trough 603 to move directly below the sponge 803. Since the wedge block 602 is now located inside the wedge groove 501, when the lifting seat 5 continues to move upward, the lifting seat 5 will drive the wedge block 602 upward, which in turn drives the L-shaped plate 601 upward. The L-shaped plate 601, through the pressure rod 703 and the sleeve 702, drives the sliding plate 701 upward, and simultaneously, the L-shaped plate 601 drives the squeezing trough 603 upward. The squeezing trough 603 wraps around the sponge 803 and squeezes it, removing the dirt inside the sponge 803. Water is squeezed out, and sewage is discharged through hose 604. Then, the lifting seat 5 begins to move down. The L-shaped plate 601 and the sliding plate 701 will automatically move down to their initial positions due to gravity. As the lifting seat 5 moves down, the wedge block 602 is squeezed out of the wedge groove 501, so that the wedge block 602 abuts against the left side of the lifting seat 5 again. During this process, the wedge block 602 and the L-shaped plate 601 move to the right. At this time, the water squeezing trough 603 moves to the right from below the sponge 803. The lifting seat 5 continues to move down until the first spring 503 returns to its initial state. At this time, the lifting seat 5 will drive the guide rod 502 to move down, so that the wiping mechanism 8 moves down to its initial position, waiting to wipe the next solar panel.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
