DETAILED DESCRIPTION

[0027] The specific embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely intended to illustrate and explain the present application, and are not intended to limit the present application.

[0028] Reference Figure 1 And Figure 4 It can be seen that the photovoltaic panel cleaning device comprises:

[0029] The support frame 1 can be arranged on the photovoltaic panel 2.

[0030] The scraper 3 is arranged on the support frame 1, the scraper 3 is perpendicular to a first direction parallel to the photovoltaic panel 2, and the edge of the scraper 3 can be engaged with the photovoltaic panel 2; and

[0031] The driving mechanism 4 can drive the support frame 1 to move along the first direction to clean the photovoltaic panel 2 by the scraper 3.

[0032] In the process of the scraper 3 being engaged with the photovoltaic panel 2 and sliding along the first direction on the surface of the photovoltaic panel 2, the scraper 3 can be in contact with the dirt.

[0033] It can be understood that the driving force exerted on the scraper 3 by the driving mechanism 4 through the support frame 1 is greater than the adhesion between the dirt and the photovoltaic panel 2, thereby breaking the adhesion between the dirt and the photovoltaic panel 2, and making the dirt separate from the surface of the photovoltaic panel 2.

[0034] In the present application, the scraper 3 is engaged with the photovoltaic panel 2, and in the process of the driving mechanism 4 driving the support frame 1 to drive the scraper 3 to slide on the photovoltaic panel 2, the scraper 3 can scrape off the dirt with strong adsorption on the photovoltaic panel 2. Therefore, the present application does not need manual cleaning of the dirt with strong adsorption on the photovoltaic panel 2, and improves the efficiency of cleaning the photovoltaic panel 2.

[0035] In some embodiments, referring to Figure 1 It can be seen that the driving mechanism 4 comprises a solar panel 401 arranged on the support frame 1.

[0036] Meanwhile, the support frame 1 is provided with a connecting frame 104 at both ends along a third direction parallel to the photovoltaic panel 2 and perpendicular to the first direction, and each connecting frame 104 is provided with a motor electrically connected to the solar panel 401.

[0037] In addition, the support frame 1 is provided with three rollers 402 spaced apart along the third direction towards the photovoltaic panel 2, two of which are close to the connecting frames 104 at both ends of the support frame 1 and are in driving connection with the motor in each connecting frame 104, and the support frame 1 is also provided with three rotating frames 404 corresponding to the three rollers 402, and the three rollers 402 are in one-to-one rotating connection with the three rotating frames 404, so that the rollers 402 are rotatably arranged on the support frame 1 and can roll on the photovoltaic panel 2.

[0038] It can be seen that the outer circumferential surface of the roller 402 is provided with a plurality of long strip-shaped anti-skid grooves 403 arranged in the axial direction of the roller 402, so as to increase the static friction between the roller 402 and the photovoltaic panel 2, and to avoid the roller 402 from slipping and scratching the photovoltaic panel 2. Figure 2 It can be seen that the support frame 1 is provided with a plurality of scrapers 3 spaced apart along the first direction on both sides, so that the weight of the support frame 1 on both sides is the same and uniformly distributed.

[0039] Figure 4 It can be seen that the front and rear scrapers 3 are staggered along the first direction, so as to ensure comprehensive coverage and cleaning of the surface of the photovoltaic panel 2.

[0040] In the utility model, the material and shape of the scraper 3 can also be adjusted according to the type of stains on the photovoltaic panel 2, so as to improve the cleaning efficiency and reduce the damage to the photovoltaic panel 2.

[0041] In some embodiments, the support frame 1 is provided with a cleaning mechanism for cleaning the dirt with low adhesion or scraped off by the scraper 3 on the photovoltaic panel 2.

[0042] In some embodiments, the support frame 1 is provided with a cleaning mechanism for cleaning the dirt with low adhesion or scraped off by the scraper 3 on the photovoltaic panel 2.

[0043] It can be seen that the cleaning mechanism includes a brush roller 5 rotatably arranged in the axial direction of the support frame 1 between the scrapers 3 at both ends of the support frame 1. Figure 1 Figure 3 It can be seen that the cleaning mechanism includes a brush roller 5 rotatably arranged in the axial direction of the support frame 1 between the scrapers 3 at both ends of the support frame 1.

[0044] It can be seen that the connecting frame 104 further includes a motor capable of driving the brush roller 5 to rotate, and the motor is also electrically connected to the solar panel 401 on the support frame 1, and the rotation direction of the brush roller 5 is opposite to the moving direction of the support frame 1, so that the dirt on the photovoltaic panel 2 can be swept out of the photovoltaic panel 2 along the first direction.

[0045] ​​Understandably, during the rotation of the brush roller 5, the bristles on it can come into contact with the dirt on the photovoltaic panel 2 and drive the dirt towards the edge of the photovoltaic panel 2 in the direction of movement of the support frame 1, thereby sweeping the dirt off the surface of the photovoltaic panel 2.

[0046] In some embodiments, the photovoltaic panel cleaning device further includes a lifting assembly that can drive the scraper 3 to move up and down in a second direction perpendicular to the photovoltaic panel 2.

[0047] Each scraper 3 is connected to the support frame 1 via a lifting assembly.

[0048] In this invention, when the photovoltaic panel cleaning device cleans the weakly adhesive dirt on the photovoltaic panel 2, the lifting component drives the scraper 3 to move upward along the second direction, and the motor driving the brush roller 5 is turned on. At the same time, the support frame 1 moves from one end of the photovoltaic panel 2 along the first direction to the other end, thereby sweeping the dirt out of the photovoltaic panel 2.

[0049] In addition, when cleaning the strongly adhesive dirt on the photovoltaic panel 2, the photovoltaic panel 2 is first moved to the position of the dirt, the lifting component is controlled to move the scraper 3 downward in the second direction, the support frame 1 drives the scraper 3 to move, thereby breaking the adhesion between the dirt and the photovoltaic panel 2, and then the scraper 3 is raised and the above process of cleaning the weakly adhesive dirt is repeated.

[0050] In some embodiments, the lifting assembly includes a telescopic drive 6 and a four-bar linkage 7 disposed on the support frame 1. The telescopic drive 6 can drive the four-bar linkage 7 to deform so as to drive the scraper 3 to move up and down relative to the photovoltaic panel 2 in a second direction.

[0051] In some embodiments, the four-bar linkage 7 includes a first link 701, a second link 702 parallel to the first link 701, and a third link 703 and a fourth link 704, both of which are respectively hinged to the first link 701 and the second link 702. The first link 701 is fixed on the support frame 1, and the fourth link 704 is connected to the scraper 3.

[0052] A fixing plate 101 is provided between the first connecting rod 701 and the support frame 1. One end of the fixing plate 101 is fixed to the support frame 1, and the other end is provided with a clamp 102. The first connecting rod 701 is located in the clamp 102.

[0053] The fixing plate 101 includes an L-shaped plate. One end of the L-shaped plate is fixed to the side of the support frame 1 while the other end is parallel to the photovoltaic panel 2. The clamping direction of the clamp 102 provided at the end is parallel to the photovoltaic panel 2 and perpendicular to the first direction.

[0054] It can be understood that the first connecting rod 701 held on the clamp seat 102 can be parallel to the photovoltaic panel 2 and perpendicular to the first direction, so that the second connecting rod 702 can be parallel to the photovoltaic panel 2, and thus the side of the scraper 3 facing the photovoltaic panel 2 can be completely attached to the surface of the photovoltaic panel 2, avoiding the scraper 3 from scratching the photovoltaic panel 2.

[0055] In some embodiments, the fourth connecting rod 704 is fixedly connected with the scraper 3 on both sides along the first direction, and it can be understood that when the scraper 3 on the front side along the first direction fails to scrape off the dirt, the scraper 3 on the rear side can continue to contact and scrape off the dirt, thereby enhancing the strength of single scraping.

[0056] In some embodiments, the telescopic driving member 6 comprises an electric push rod 601, which is hinged with the third connecting rod 703 or the fourth connecting rod 704.

[0057] In the utility model, the electric push rod 601 pushes the fourth connecting rod 704 to rotate around one end of the corresponding first connecting rod 701, and moves the second connecting rod 702 in the direction pushed by the electric push rod 601, so that the end of the third connecting rod 703 hinged with the second connecting rod 702 is also subjected to the pushing force of the electric push rod 601.

[0058] It can be understood that the third connecting rod 703 and the fourth connecting rod 704 rotate synchronously upward around both ends of the first connecting rod 701 in the direction pushed by the electric push rod 601, thereby driving the second connecting rod 702 to move upward relative to the photovoltaic panel 2 along the second direction. It is worth noting that due to the synchronous rotation of the third connecting rod 703 and the fourth connecting rod 704, the second connecting rod 702 and the scraper 3 connected on the second connecting rod 702 can be parallel to the photovoltaic panel 2 during the process of rising or falling relative to the photovoltaic panel 2.

[0059] Similarly, when the electric push rod 601 is retracted, it can drive the second connecting rod 702 to move downward relative to the photovoltaic panel 2 along the second direction. In this way, the scraper 3 is controlled to rise and fall along the second direction through the lifting assembly.

[0060] In some embodiments, referring to Figure 5 It can be understood that the electric push rod 601 and the support frame 1 are also connected through the L-shaped fixing plate 101, and the side of the fixing plate 101 facing the photovoltaic panel 2 is provided with a fixing seat 103 extending towards the photovoltaic panel 2, and the electric push rod 601 is fixed on the side of the fixing seat 103 facing the fourth connecting rod mechanism 7.

[0061] In some embodiments, referring to Figure 1 It can be understood that the support frame 1 is provided with a limiting piece 8 at both ends along the second direction, and the limiting piece 8 is used to limit the deviation of the support frame 1 from the photovoltaic panel 2.

[0062] In some embodiments, the limiting member 8 comprises a plurality of limiting wheels 801, which are arranged on the support frame 1 and the wheel surface of each limiting wheel 801 is in contact with the side surface of the photovoltaic panel 2.

[0063] Each limiting wheel 801 is axially arranged on the bottom end surface of the connecting frame 104 and can rotate. It can be understood that when the support frame 1 moves on the photovoltaic panel 2, the limiting wheels 801 at both ends of the support frame 1 are clamped on both sides of the photovoltaic panel 2 along the third direction, so that the support frame 1 cannot be offset relative to the photovoltaic panel 2 along the third direction.

[0064] The utility model also provides a photovoltaic equipment, including a plurality of photovoltaic panels 2 and the photovoltaic panel cleaning device above.

[0065] The preferred embodiments of the utility model are described in detail above in combination with the drawings, but the utility model is not limited to this. Within the technical concept range of the utility model, the technical scheme of the utility model can be subjected to various simple modifications. In order to avoid unnecessary repetition, the utility model does not further illustrate various possible combination modes. But these simple modifications and combinations should also be regarded as the disclosed contents of the utility model and all belong to the protection range of the utility model.
