[0027] Among various new energy sources, solar photovoltaic power generation has a good development space and prospects. Since dust on the surface of the solar panel 600 will greatly reduce the light transmittance, thereby reducing the efficiency of photovoltaic power generation. Therefore, dust accumulates on the surface of the solar panel 600 for a long time, which has a certain impact on the solar panel's absorption of sunlight. At present, the domestic cleaning of the solar panel 600 adopts a cleaning strip 200 to automatically clean the solar panel 600.

[0029] Two guide rails 100 are respectively arranged on the left and right sides of the solar panel 600, and the two guide rails 100 are arranged parallel to each other. A sliding fixing assembly 500 is slidably installed on the guide rails 100, and the sliding fixing assembly 500 is used to fix the cleaning strip 200;

[0030] Both ends of the cleaning strip 200 are fixed to the sliding fixing assembly 500 respectively, and the bottom surface of the cleaning strip 200 directly contacts the surface of the solar panel 600;

[0031] The two ends of the cleaning installation block 300 are respectively arranged at the lower ends of the two guide rails 100, that is, the bottom end of the solar panel 600. The cleaning installation block 300 is provided with an extrusion channel 310. The height of the extrusion channel 310 is less than the thickness of the cleaning bar 200. The extrusion channel 310 is used for the cleaning bar 200 to pass through, so that the cleaning bar 200 passes through the extrusion channel 310 in a compressed state, thereby squeezing out the sewage absorbed by the cleaning bar 200.

[0032] The driving member 400 is in driving connection with the sliding fixing assembly 500 , so that the sliding fixing assembly 500 slides back and forth along the guide rail 100 and drives the cleaning strip 200 to reciprocate through the extrusion channel 310 , thereby achieving a self-cleaning effect for the cleaning strip 200 .

[0033] The number of the driving member 400 can be two, which respectively drive the sliding fixing assembly 500 to slide along the guide rail 100, and can be specifically a ball screw transmission structure. The driving member 400 includes a ball screw rotatably arranged on the guide rail 100, a sliding block 510, and a driving motor, the sliding block 510 is slidably arranged on the guide rail 100, and the driving motor is connected to the driving motor by transmission. In other embodiments, it can also be one, such as driven by a belt transmission mechanism, a cylinder, etc.

[0034] When it is dry, the cleaning strip 200 can be directly driven by the driving member 400 to slide on the surface of the solar panel 600 to play a cleaning role, thereby improving the absorption rate of sunlight by the solar panel 600; on rainy days, the cleaning strip 200 can be cleaned with rainwater, specifically: the driving member 400 drives the cleaning strip 200 to pass through the extrusion channel 310, the dirtier sewage will be squeezed out, and then the cleaning strip 200 reabsorbs clean rainwater for cleaning, the cleaning strip 200 reciprocates through the extrusion channel 310, squeezes out the sewage, and repeatedly absorbs clean water, and the cleaning strip 200 is cleaned without manual disassembly and cleaning.

[0035] Furthermore, the extrusion channel 310 includes a cleaning passing area and a sliding clamping passing area. The sliding clamping passing area is arranged at both ends of the cleaning passing area. The cross-section of the sliding clamping passing area is adapted to the sliding fixing component 500, and the sliding clamping passing area facilitates the passage of the sliding fixing component 500.

[0036] Furthermore, guide plates are provided on the upper and lower sides of the channel opening of the extrusion channel 310, which are not shown in the figure, so as to facilitate the cleaning strip 200 to enter the extrusion channel 310 and squeeze out the sewage better without damaging the cleaning strip 200.

[0037] Further improvement, the cleaning strip 200 is a sponge member or a flexible cloth. It is relatively soft and warm, and will not damage the surface of the solar panel 600 while cleaning the surface of the solar panel 600. Moreover, both materials have good water absorption effect, and are better squeezed by the squeezing channel 310 to achieve a self-cleaning effect. The cleaning strip 200 has a certain thickness, and can be better cleaned by squeezing the sewage.

[0038] The solar panel 600 has a long service life, while the cleaning strip 200 is exposed to the outdoors for a long time, exposed to the wind, sun and rain, and will age over time. Therefore, as a further improvement, the cleaning strip 200 can be detachably fixed to the sliding fixing assembly 500 to facilitate the replacement of the aged cleaning strip 200.

[0039] In this embodiment, the sliding fixing assembly 500 includes a sliding block 510 and a clamping member 520 disposed on the sliding block 510 , and the sliding block 510 is slidably disposed on the guide rail 100 .

[0040] One of the clamping members 520 is slidably fixed to the sliding block 510 along the extension direction of the cleaning strip 200. When both ends of the cleaning strip 200 are clamped by the clamping members 520, the clamping member 520 at one end can be moved to straighten the cleaning strip 200 and put it in a certain tension state, so as to better clean the solar panel 600. When clamping the cleaning strip 200, it is not necessary to tighten the cleaning strip 200. The clamping member 520 can be directly used to clamp the cleaning strip 200, and the position of the sliding block 510 can be fixed later to achieve the purpose of pulling it closer. Of course, both clamping members 520 are slidably set on the sliding block 510.

[0041] The clamping member 520 includes a fixed column 521, a torsion spring, a clamping plate 523, and a bottom plate 524. The fixed column 521 is fixed to the upper surface of the bottom plate 524. The clamping plate 523 is provided with a hinged end and an abutting end. The abutting end abuts against the upper surface of the bottom plate 524. The hinged end is hinged to the fixed column 521. The torsion spring is provided between the hinged end and the fixed column 521. The clamping plate 523 is pressed, and the clamping plate 523 rotates relative to the fixed column 521, and the abutting end is separated from the upper surface of the bottom plate 524. At this time, the cleaning strip 200 can be placed between the abutting end and the upper surface of the bottom plate 524, and the clamping plate 523 is loosened to clamp one end of the cleaning strip 200.

[0042] In some other embodiments, the clamping member 520 can be a C-shaped groove, one end of the cleaning strip 200 is placed in the C-shaped groove, an extrusion block is provided in the C-shaped groove, the extrusion block is provided with a screw extending up and down, the screw is threadedly connected to the upper side wall of the C-shaped groove, so that the extrusion block can be adjusted up and down and fixed to the upper side wall of the C-shaped groove, and the screw is rotated so that the extrusion block presses and fixes one end of the cleaning strip 200.

[0043] When the cleaning strip 200 is tightened, the clamping member 520 may be misaligned, so the sliding block 510 is provided with a sliding groove 511 extending left and right, and the clamping member 520 is slidably fixed in the sliding groove 511. In this embodiment, the bottom plate 524 is slidably provided in the sliding groove 511, and the sliding groove 511 serves as a guide limiter. In the process of moving the clamping member 520, the two clamping members 520 are kept in the same straight line without relative misalignment. In some other embodiments, the bottom plate 524 can also be the sliding block 510, that is, the clamping member 520 is directly fixedly provided on the sliding block 510.

[0044] The sliding block 510 is provided with a first positioning hole, the clamping member 520 is provided with a second positioning hole, and the sliding fixing assembly 500 further includes a latch 525, which is plugged into the first positioning hole and the second positioning hole. There are two latches 525, which provide a better fixing effect.

[0045] After the cleaning strip 200 is clamped, the clamping member 520 is moved, and the latch 525 is inserted into the first positioning hole and the second positioning hole to fix the position of the clamping member 520. At this time, the cleaning strip 200 is in a straightened and tight state. The fixing structure with the latch 525 is simple and easy to operate.

[0046] In some other embodiments, the bottom plate 524 may also be clamped in the tightened position by a clamping structure. The bottom plate 524 may also be fixed to the sliding block 510 by bolts.

[0047] As a further improvement, the cleaning strip 200 is a sponge member or a flexible cloth, which is relatively soft and warm, and will not damage the surface of the solar panel 600 while cleaning the surface of the solar panel 600. Moreover, both materials have good water absorption effect, and are better squeezed by the squeezing channel 310 to achieve a self-cleaning effect.

[0048] The utility model also provides an embodiment of a solar panel, comprising any one of the above-mentioned self-cleaning solar panel structures and a solar panel 600. The solar panel 600 is provided with a diagonal support device, so that the solar panel 600 is arranged inclined to the ground and can better absorb sunlight.

[0049] The two guide rails 100 are respectively arranged on both sides of the solar panel 600, and the cleaning installation block 300 is arranged at the bottom of the solar panel 600. Being arranged at the bottom of the solar panel 600 helps the cleaning strip 200 to self-clean better. The reason is: when it rains, rainwater will slide down along the surface of the solar panel 600 and gather at the bottom of the solar panel 600, which helps the sewage squeezed out by the cleaning strip 200 to be washed away by rainwater in time, and absorb clean rainwater when returning to its original state, thus achieving a better cleaning effect. In other embodiments, the cleaning installation block 300 can also be arranged on the top of the solar panel 600.

[0050] The solar panel 600 has a self-cleaning cleaning strip 200, and the cleaning strip 200 can clean itself when it rains. There is no need to manually disassemble the cleaning strip 200 for cleaning regularly, which is more convenient to use.
