Description

Technical Field

[0001] The invention belongs to the technical field of photovoltaic panel cleaning, and specifically discloses a fully automatic photovoltaic cleaning robot and a use method thereof. Background Art

[0002] The cleaning of photovoltaic panels is crucial to their performance and long-term use. First of all, regular cleaning of photovoltaic panels can improve the efficiency of power generation. The dust and dirt accumulated on the surface of photovoltaic panels will block the direct sunlight from reaching the photovoltaic panels, thereby reducing the efficiency of photoelectric conversion. These obstructions can be removed by cleaning, so that the photovoltaic panels can better absorb sunlight, thereby improving the efficiency of power generation. In the past, manual cleaning was mainly done by using a long-handled velvet mop or a soft brush to clean the dust and dirt on the surface of the photovoltaic panels. In the prior art, photovoltaic panel cleaning robots are used to clean them, greatly improving the cleaning efficiency. However, when the snow covers a certain degree in winter, it is not easy to clean directly, and the existing cleaning robots are basically suitable for normal square photovoltaic panels. For example, when facing photovoltaic panels with curved surfaces, the previous cleaning robots are easy to slip when moving on the curved and sloped photovoltaic panel surface, and the cleaning robots that move through the slide rails are based on linear movement, so they cannot be effectively cleaned.

[0015] S3: When the cleaning roller is working, the dust remaining after the cleaning roller is cleaned is collected by using a vacuum pump. The cleaning roller is arranged inside the cleaning room for cleaning, and the dust is immediately sucked from the air outlet to reduce the dust flying around outside the equipment.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The No. 1 wheel, No. 2 wheel and two groups of side ball bearings on both sides are clamped and installed on both sides of the photovoltaic panel frame respectively. When working, the No. 2 motor drives the connected No. 2 wheel and No. 2 synchronous wheel to rotate, and the sleeved synchronous belt drives another group of No. 2 synchronous wheels and No. 2 wheels to move horizontally and linearly on the photovoltaic panel frame. The rotation setting of the cleaning room and the pneumatic room rotates relative to each other when facing the curved photovoltaic panel, so that the two groups of No. 2 connecting shafts pull the No. 1 double-hook spring, which can automatically change the angle when facing the curved photovoltaic panel. At the same time, when the cleaning room and the pneumatic chamber rotate relative to each other, the two groups of No. 2 synchronous wheels will rotate downward and close together, and the No. 2 double-hook spring pulls the connecting rod to rotate along the No. 2 fixed axis to meet the synchronous belt. When the position of the two groups of No. 2 synchronous wheels changes, the two groups of auxiliary wheels will be pressed on the synchronous belt for pre-tightening, which meets the transmission work of the two groups of No. 2 synchronous wheels and No. 2 wheels, is suitable for driving work on the curved photovoltaic panel, and effectively cleans the two photovoltaic panels.

[0018] The No. 1 synchronous wheel connected by the No. 1 motor drives the sleeved synchronous toothed belt to rotate, and drives the other two groups of No. 1 synchronous wheels to rotate respectively, and drives the cleaning roller and the spiral roller to rotate at the same time. The drive of the two groups of hydraulic cylinders will push the two groups of movable plates on both sides to rotate along the two groups of No. 1 fixed shafts respectively, and the upper and lower positions of the cleaning rollers and spiral rollers on the front and rear sides can be switched. The rotating cleaning roller can clean the dust on the surface of the photovoltaic panel, and the rotating spiral roller can be used with the rear shell to shovel the accumulated snow. At the same time, the two oppositely arranged spiral rollers can transport the snow to both sides to avoid the influence of the resistance accumulated on the front side of the spiral roller on the movement, and can work according to different cleaning conditions.

[0019] When the cleaning roller is working, a vacuum pump can be used to absorb the dust remaining after the cleaning roller is cleaned through the air suction port, and then discharged into the collection chamber for collection. The cleaning roller is arranged inside the cleaning chamber for cleaning, and the vacuum port is used to immediately absorb dust, thereby reducing dust flying around outside the equipment and preventing the flying dust from falling onto the photovoltaic panel again after the equipment is moved. When the spiral roller is working, two sets of air pumps can be used in conjunction with several sets of wind guide plates to blow the remaining snow to both sides at an angle, thereby improving the cleaning effect.

4. A method for using a photovoltaic cleaning robot, used to operate a fully automated photovoltaic cleaning robot according to any one of claims 1 to 3, characterized in that: The following steps are involved: S1: The second motor (516) is moved on the photovoltaic panel frame as a whole, and the cleaning chamber (1) and the pneumatic chamber (2) are rotated to automatically change their angles when facing the curved photovoltaic panel. At the same time, the second double-hook spring (515) pulls the connecting rod (511) to meet the driving work, thereby effectively cleaning the two photovoltaic panels; S2: The cleaning roller (31) and the spiral roller (35) are driven to rotate by the first motor (37), and the cleaning rollers (31) and the spiral rollers (35) on the front and rear sides are switched in coordination with the driving of the two sets of hydraulic cylinders (310), so as to clean the dust on the surface of the photovoltaic panel and transport the accumulated snow to both sides, thereby avoiding the influence of the resistance generated by the accumulation on the front side of the spiral roller (35) on the movement; S3: When the cleaning roller (31) is working, the dust remaining after the cleaning roller (31) is cleaned is sucked and collected by using the dust suction pump (42). The cleaning roller (31) is arranged inside the cleaning chamber (1) for cleaning, and the dust is immediately sucked by the air suction port (48), thereby reducing the dust from flying around outside the equipment.
