This photovoltaic panel with a snow removal device includes a photovoltaic panel group body and a snow removal device installed on the photovoltaic panel group body. The snow removal device includes an upper rotating shaft, a lower rotating shaft, a rotating shaft bracket, a synchronous pulley, a synchronous belt, a snow scraping strip, a snow scraping strip pulling-down mechanism, and a snow scraping strip rebounding mechanism. Among them, the upper and lower parts of the photovoltaic panel group body are respectively provided with an upper rotating shaft and a lower rotating shaft, and a synchronous pulley is fixed at each end of the upper rotating shaft and the lower rotating shaft. Two synchronous pulleys on the same side of the photovoltaic panel group body are synchronously connected through a synchronous belt, and both ends of the snow scraping strip are fixedly connected to the two synchronous belts. The present utility model utilizes the rotating shaft, synchronous pulley, synchronous belt, snow scraping strip, and snow scraping strip pulling-down mechanism to simultaneously remove snow from multiple photovoltaic panels. The snow scraping strip rebounding mechanism enables the snow scraping strip to automatically return to the initial position at the top of the photovoltaic panel group body without manual operation by the staff.

[0004] Although the photovoltaic panel with a snow removal device disclosed in this patent improves the snow removal efficiency, the snow removal effect of this photovoltaic panel is not good. Therefore, it is very necessary to design a solar photovoltaic module with a snow removal function. Summary of the Invention

[0005] The purpose of the present invention is to address the above problems existing in the prior art and propose a solar photovoltaic module with a snow removal function, which has the characteristic of good snow removal effect.

[0006] The purpose of the present invention can be achieved by the following technical solutions: A solar photovoltaic module with a snow removal function includes a module body with a mounting frame. It is characterized in that horizontal tracks are arranged at both the upper and lower ends of the mounting frame, a snow removal frame is slidably arranged between the two tracks, the snow removal frame is connected to a driving structure that can drive it to move back and forth, and a scraping strip and a brush strip are arranged on the snow removal frame.

[0007] The working principle of the present invention is as follows: The driving structure drives the snow removal frame to move horizontally on the track. The scraping strip on the snow removal frame pushes off most of the snow on the surface of the photovoltaic panel, and the brush strip cleans the surface of the photovoltaic panel.

[0008] A mounting bar is horizontally fixed to the upper end of the snow removal frame. Two guide seats are fixed to the mounting bar. A power rod is horizontally slidably arranged in the guide seat. A reciprocating plate is connected between the two power rods. A return spring is sleeved on the power rod. One end of the return spring abuts against the reciprocating plate, and the other end of the return spring abuts against the guide seat. One end of the reciprocating plate is hinged to one end of the first auxiliary push plate. One end of the mounting bar is hinged to one end of the second auxiliary push plate. The other end of the second auxiliary push plate is hinged to the other end of the first auxiliary push plate. And the first auxiliary push plate and the second auxiliary push plate can form a V shape or a straight line, and can switch back and forth between the straight line and the V shape. The power rod has a toothed portion. A linkage shaft is horizontally rotatably arranged on the mounting bar, and the linkage shaft is perpendicular to the track. A linkage gear is installed at one end of the linkage shaft, and the linkage gear meshes with the rack portion. The other end of the linkage shaft is connected with a friction wheel through a one-way bearing. Among them, a friction strip matched with the friction wheel is also connected to the upper track, and a plurality of relief notches evenly distributed are also provided on the friction strip.

The linkage shaft drives the friction wheel to rotate on the friction strip, compressing the return spring, and the first auxiliary push plate and the second auxiliary push plate are in a V shape; when the friction wheel rotates to the relief notch, the return spring pushes the reciprocating plate to reset, the linkage gear rotates in the reverse direction, and at the same time, the friction wheel freely rotates under the action of the one-way bearing, and the first auxiliary push plate and the second auxiliary push plate are switched to a straight line, so as to use the auxiliary push plate to reciprocate and push the snow above, which is beneficial to the snow on the photovoltaic panel to fall off.

[0010] The driving structure includes a driving motor. A rack is connected to the track, and the rack is parallel to the track. The driving motor is installed on the snow removal frame.

A plurality of guide wheels for guiding the steel wire rope and a plurality of limit rings for limiting the steel wire rope are also provided on the snow removal frame.

[0013] With the above structure, the snow removal frame drives the scraping strip to move horizontally on the surface of the photovoltaic panel. At the same time, the auxiliary pushing plate pushes the snow downward from above, causing the pushed snow to fall on the receiving plate. The receiving plate is pressed downward under pressure and compresses the support spring. The receiving plate drives the scraping strip to swing downward through the steel wire rope; after the snow on the receiving plate falls off, the support spring drives the receiving plate to reset, and at the same time, the counterweight drives the scraping strip to swing upward and reset, enabling the scraping strip to swing slightly up and down within a small range to shake off the snow, and the snow removal effect is good.

[0014] There are also several toothed rods in the shape of hooks on the scraping strip.

[0015] With the above structure, the toothed rods can be used to loosen the snow.

One end of the reciprocating plate 3 is hinged to one end of the first auxiliary push plate 5. One end of the installation strip 11 is hinged to one end of the second auxiliary push plate 10. The other end of the second auxiliary push plate 10 is hinged to the other end of the first auxiliary push plate 5. And the first auxiliary push plate 5 and the second auxiliary push plate 10 can form a V shape or a straight shape, and can switch back and forth between the straight shape and the V shape. The power rod 7 has a toothed part. A linkage shaft 8 is horizontally rotatably arranged on the installation strip 11, and the linkage shaft 8 is perpendicular to the track 2. A linkage gear 9 is installed at one end of the linkage shaft 8, and the linkage gear 9 meshes with the rack 13 part. The other end of the linkage shaft 8 is connected to a friction wheel 31 through a one-way bearing 32. Among them, a friction strip 33 that cooperates with the friction wheel 31 is also connected to the upper track 2. The friction strip 33 also has a number of evenly distributed relief notches 33a.

[0031] With the above structure, when the snow removal frame 17 moves horizontally, the snow removal frame 17 drives the guide seat 6 to move horizontally through the installation strip 11. The gear 12 on the power rod 7 meshes with the linkage gear 9. Under the action of the one-way bearing 32, the friction wheel 31 is locked. The linkage shaft 8 drives the friction wheel 31 to rotate on the friction strip 33, compressing the return spring 4. The first auxiliary push plate 5 and the second auxiliary push plate 10 are in a V-shaped configuration; when the friction wheel 31 rotates to the relief notch 33a, the return spring 4 pushes the reciprocating plate 3 to reset, the linkage gear 9 rotates in the reverse direction, and at the same time, under the action of the one-way bearing 32, the friction wheel 31 rotates freely, and the first auxiliary push plate 5 and the second auxiliary push plate 10 switch to a linear configuration, thereby using the auxiliary push plates to reciprocally push the snow above, facilitating the snow on the photovoltaic panel to fall off.

[0032] The driving structure includes a driving motor 16. A rack 13 is connected to the track 2, and the rack 13 is parallel to the track 2.

A counterweight 14 is installed at one end of the swing rod 15. The other end of the swing rod 15 is hinged to a scraping strip 20. The two swing rods 15, the scraping strip 20, and the snow removal frame 17 form a parallelogram. The receiving plate 19 is connected to the upper end of the scraping strip 20 through a steel wire rope 26. The snow removal frame 17 also has a plurality of guide wheels 22 for guiding the steel wire rope 26 and a plurality of limit rings 23 for limiting the steel wire rope 26.

[0035] With the above structure, the snow removal frame 17 drives the scraping strip 20 to move horizontally on the surface of the photovoltaic panel. At the same time, the auxiliary push plates push the snow downward from above, causing the pushed snow to fall on the receiving plate 19. The receiving plate 19 is pressed downward under the pressure and compresses the support spring 28. The receiving plate 19 drives the scraping strip 20 to swing downward through the steel wire rope 26; after the snow on the receiving plate 19 falls off, the support spring 28 drives the receiving plate 19 to reset, and at the same time, the counterweight 14 drives the scraping strip 20 to swing upward and reset, enabling the scraping strip 20 to swing slightly up and down to shake off the snow, and the snow removal effect is good.

[0036] The scraping strip 20 also has a plurality of toothed rods 25 in the shape of hooks.

[0037] With the above structure, the snow can be loosened by the rack bar 25.

[0038] The material of the scraping strip 20 is stainless steel.

[0039] A rubber sleeve 24 is also sleeved on the rack bar 25.

[0040] With the above structure, damage to the surface of the photovoltaic panel caused by the rack bar 25 is prevented.

[0041] On the side of the snow removal frame 17, there is also an auxiliary block 27 in a triangular shape.

[0042] The lower surface of the installation frame 1 is lower than the surface of the photovoltaic panel, preventing the snow scraped by the scraping strip 20 from accumulating on the lower track 2 of the installation frame 1.

[0043] The working principle of the present invention is as follows: The driving structure drives the snow removal frame 17 to move horizontally on the track 2. The scraping strip 20 on the snow removal frame 17 pushes off most of the snow on the surface of the photovoltaic panel. The brush strip 21 cleans the surface of the photovoltaic panel. The first auxiliary push plate 5 and the second auxiliary push plate 10 push the snow above the photovoltaic panel. The snow falls on the receiving plate 19. Under the action of the support spring 28, the receiving plate 19 drives the scraping strip 20 to vibrate slightly up and down, removing the residual snow on the surface of the scraping strip 20, keeping the scraping strip 20 clean, thereby improving the cleaning effect of the scraping strip 20 and achieving a good snow removal effect.
