Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic modules, in particular to a cleaning device for maintaining photovoltaic modules. Background Art

[0002] With the technological progress in my country in recent years, large areas of photovoltaic panels have been laid in major areas. Photovoltaic power generation requires a good lighting surface, because the cleaner the photovoltaic panels, the higher the efficiency of converting sunlight. However, in fact, when these photovoltaic panels are put into use, their surfaces will inevitably be contaminated with dust, which will affect the actual lighting.

[0003] In this regard, China's patent application number: CN202110356176.0 discloses a self-cleaning photovoltaic device, including a photovoltaic panel arranged at a certain angle, an upper sweeping rod is provided on the upper side of the photovoltaic panel, and a lower sweeping rod is provided on the lower side of the photovoltaic panel. The lower sweeping rod can be driven by an external force to approach the upper sweeping rod along the surface of the photovoltaic panel to clean the photovoltaic panel. An elastic bag is provided between the upper sweeping rod and the lower sweeping rod, which is located on the other two sides of the photovoltaic panel respectively, and the elastic bag provides the lower sweeping rod with reset.

[0004] The photovoltaic device can clean the photovoltaic panels through the upper and lower sweeping rods, but the above structure can only clean one group of photovoltaic panels. In real life, since most photovoltaic panels are laid in arrays and there are a large number of them, each group of photovoltaic panels is provided with a set of cleaning structures, which is wasteful and increases the cost of use, which is not conducive to energy conservation and environmental protection. In addition, flushing with clean water will make the surface of the photovoltaic panels moist, and the dust that subsequently falls on the photovoltaic panels will be soaked, and will then adhere more firmly to the surface of the photovoltaic panels, which is not conducive to the long-term use of the photovoltaic panels.

[0005] Therefore, in order to solve the above problems, a cleaning device for maintaining photovoltaic modules is proposed. Summary of the Invention

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] See also Figure 1-Figure 7 , an embodiment provided by the present invention:

[0031] The mounting base 1, rotating base 12, photovoltaic panel body 18, electric telescopic rod 22, lower roller mechanism 23, upper roller 24, cleaning brush barrel 25 and electric push rod 36 used in this application are products that can be directly purchased on the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be repeated here.

[0032] A photovoltaic module maintenance and cleaning device includes: a mounting base 1, a rotating base 12 movably mounted on the top of the mounting base 1 via a bearing, a support frame 13 fixedly mounted on the top surface of the rotating base 12, a mounting frame 14 movably mounted on the upper end of the support frame 13 via a bearing, a protective outer frame 16 fixedly connected to the top surface of the mounting frame 14, and a photovoltaic panel body 18 fixedly mounted on the inner side of the protective outer frame 16;

[0033] The top surface of the mounting base 1 is fixedly connected to a worm wheel 11, the bottom surface of the mounting frame 14 is fixedly connected to a limit frame 15, a movable groove 17 is opened on the surface of the protective outer frame 16, and the front and rear ends of the mounting frame 14 are fixedly connected to the first sprocket 19;

[0034] A cleaning structure 2 is mounted on the protective outer frame 16. The cleaning structure 2 includes a fixed block 21, which is movably mounted on the right end of the top surface of the protective outer frame 16. An electric telescopic rod 22 is movably mounted on the bottom surface of the fixed block 21 through a bearing. The protruding end of the electric telescopic rod 22 is fixedly connected to a lower roller mechanism 23. An upper roller 24 and a cleaning brush cylinder 25 are mounted on the surface of the fixed block 21.

[0035] The outer end of the second sprocket 31 is meshed with a chain body 32, and the end of the second sprocket 31 is fixedly connected to the large bevel gear 33. The inner side of the rotating seat 12 is movably mounted with a worm 34 through a bearing, and a small bevel gear 35 is fixedly mounted on the surface of the worm 34. The top surface of the rotating seat 12 is fixedly mounted with an electric push rod 36, and the protruding end of the electric push rod 36 is fixedly connected to the guide rod 37. The cleaning structure 2 can reciprocate on the corresponding two groups of photovoltaic panel bodies 18 to clean the two groups of photovoltaic panel bodies 18 at the same time, which is more efficient and greatly reduces the cost of use, which is conducive to the promotion and use of the device. The rotating structure 3 can operate when the photovoltaic panel body 18 rotates to drive the rotating seat 12 to rotate, so as to adjust the inclination direction of the two groups of photovoltaic panel bodies 18 and ensure the light receiving effect of the two groups of photovoltaic panel bodies 18.

[0036] Furthermore, the mounting frame 14, the limiting frame 15, the protective outer frame 16, the movable groove 17, the photovoltaic panel body 18, the first sprocket 19, the electric push rod 36 and the guide rod 37 are respectively provided in two groups. The two groups of photovoltaic panel bodies 18 are respectively located on the left and right sides of the top surface of the rotating seat 12. The two groups of photovoltaic panel bodies 18 are both kept tilted to the right. The setting of the two groups of photovoltaic panel bodies 18 can ensure the conversion efficiency of sunlight. The photovoltaic panel body 18 is tilted to the right to ensure the reception effect of sunlight. When the two groups of protective outer frames 16 are rotated horizontally, the interiors of the two groups of movable grooves 17 can be aligned and communicated, and the cleaning structure 2 can move on the two groups of photovoltaic panel bodies 18 to improve the cleaning efficiency and reduce costs.

[0037] Furthermore, the worm gear 11 is located on the inner side of the rotating seat 12 and is engaged with the worm 34. The two sets of limit frames 15 are respectively installed at the adjacent ends of the two sets of mounting frames 14. The first sprocket 19 is located on the inner side of the support frame 13. The two sets of first sprockets 19 are engaged with the chain body 32. The worm gear 11 can cooperate with the rotating structure 3 on the inner side of the rotating seat 12, so that the rotating seat 12 rotates when the cleaning structure 2 is running. When the photovoltaic panel body 18 rotates, the chain body 32 can be driven by the first sprocket 19 to transmit, so that the second sprocket 31 rotates to drive the small bevel gear 35 to rotate, so that the rotating seat 12 rotates and adjusts the inclination direction of the two sets of photovoltaic panel bodies 18.

[0038] Furthermore, the upper roller 24 and the lower roller mechanism 23 are respectively located on the upper and lower sides of the protective outer frame 16, and the upper roller 24, the lower roller mechanism 23 and the protective outer frame 16 cooperate with each other. The lower roller mechanism 23 and the upper roller 24 are used to move the fixed block 21 on the protective outer frame 16, and the cleaning brush cylinder 25 is used to clean the top surface of the photovoltaic panel body 18. The cleaning structure 2 can move back and forth on the two groups of protective outer frames 16 through the movable groove 17 to clean the two groups of photovoltaic panel bodies 18 at the same time, thereby improving the cleaning efficiency and reducing costs.

[0039] Furthermore, two groups of rotating structures 3 are provided, and the two groups of rotating structures 3 are installed on the front and rear sides of the rotating seat 12, and are symmetrical with respect to the center of the worm gear 11. The setting of the two groups of rotating structures 3 can ensure that the power when the photovoltaic panel body 18 is tilted can drive the rotating seat 12 to rotate horizontally, thereby ensuring the rotational stability of the rotating seat 12.

[0040] Furthermore, a triangle is formed between the second sprocket 31 and the two groups of first sprockets 19. One end of the second sprocket 31 is located on the inner side of the rotating seat 12. The large bevel gear 33 is meshed with the small bevel gear 35. The diameter of the large bevel gear 33 is larger than the diameter of the small bevel gear 35. The rotation of the large bevel gear 33 can drive the worm 34 to rotate through the small bevel gear 35 to drive the rotating seat 12 to rotate on the mounting seat 1, adjusting the orientation of the two groups of photovoltaic panel bodies 18. At the same time, the large bevel gear 33 and the small bevel gear 35 cooperate with each other, so that the rotation of the photovoltaic panel body 18 can enable the rotating seat 12 to rotate 180°, thereby realizing the adjustment of the tilt orientation of the photovoltaic panel body 18.

[0041] Furthermore, the worm 34 is engaged with the worm wheel 11, and two sets of electric push rods 36 are installed in the middle of the top surface of the rotating seat 12, and are respectively located on the lower side of the two sets of photovoltaic panel bodies 18. The guide rod 37 is slidably installed inside the limit frame 15. When the worm 34 rotates, it can rotate outside the worm wheel 11 to rotate the rotating seat 12. The guide rod 37 can slide inside the limit frame 15 to support and limit the inclination angle of the photovoltaic panel body 18.

[0042] Working principle: When in use, the electric push rod 36 on the right side rises, and the electric push rod 36 on the left side falls, and the guide rod 37 and the limit frame 15 cooperate to keep the two sets of photovoltaic panel bodies 18 in an inclined state to improve the effect of receiving light;

[0043] When it is necessary to clean the dust on the surface of the photovoltaic panel body 18, the electric telescopic rod 22 is controlled to extend, so that the lower roller mechanism 23 is away from the fixed block 21, and the upper roller 24 is placed downward on the right end of the right group of protective outer frames 16, and the electric telescopic rod 22 is controlled to reset, and the lower roller mechanism 23 is close to the fixed block 21, and the upper roller 24 is stuck in the bottom surface of the movable groove 17, so that the cleaning structure 2 can be stably installed on the protective outer frame 16, and the lower roller mechanism 23 and the upper roller 24 are started. The lower roller mechanism 23 and the upper roller 24 can roll in the movable groove 17, so that the cleaning structure 2 can start to move on the protective outer frame 16, and the cleaning brush cylinder 25 can be started, and the dust on the surface of the photovoltaic panel body 18 can be cleaned by the cleaning brush cylinder 25;

[0044] By controlling the left group of electric push rods 36 to rise and the right group of electric push rods 36 to fall, the two groups of photovoltaic panel bodies 18 can be rotated counterclockwise together, and the two groups of photovoltaic panel bodies 18 remain horizontal, and the two groups of protective outer frames 16 fit together. The two groups of movable grooves 17 are internally connected, and the cleaning structure 2 can be moved from the right group of photovoltaic panel bodies 18 to the left group of photovoltaic panel bodies 18, so that the two groups of photovoltaic panel bodies 18 can be cleaned at the same time, which improves the cleaning efficiency of the photovoltaic panel bodies 18 and greatly reduces the cost of use. At the same time, the left group of electric push rods 36 are controlled to continue to rise, and the right group of electric push rods 36 are controlled to continue to fall, so that the two groups of photovoltaic panel bodies 18 continue to rotate and eventually are in a state tilted to the left, and the cleaning structure 2 moves from the right end of the right group of protective outer frames 16 to the left end of the left group of protective outer frames 16.

[0045] When the photovoltaic panel body 18 rotates, it can drive the mounting frame 14 to rotate on the support frame 13, and the mounting frame 14 drives the first sprocket 19 to rotate in the support frame 13. The rotation of the first sprocket 19 drives the chain body 32 to transmit, and the chain body 32 drives the second sprocket 31 to rotate, and the second sprocket 31 drives the large bevel gear 33 to rotate, and the large bevel gear 33 is engaged with the small bevel gear 35. The rotation of the large bevel gear 33 drives the worm 34 to rotate through the small bevel gear 35, and the worm 34 is engaged with the worm wheel 11, and the worm wheel 11 is installed. The mounting base 1 is fixed on the ground, and the rotating base 12 equipped with a worm 34 is movably installed on the top of the mounting base 1 through a bearing. Therefore, when the worm 34 rotates, it will rotate outside the worm wheel 11 and drive the rotating base 12 to rotate on the mounting base 1, and the positions of the left and right groups of photovoltaic panel bodies 18 can be adjusted so that the two groups of photovoltaic panel bodies 18 still remain tilted to the right, ensuring the light receiving effect of the two groups of photovoltaic panel bodies 18, and the cleaning structure 2 is still located at the right end of the right group of protective outer frames 16, which can be prepared for the next operation.
