[0030] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.

[0031] Next, refer to Figures 1-9 Describe the inspection and cleaning system 1 for photovoltaic panels according to an embodiment of the present invention.

[0032] The inspection and cleaning system 1 for photovoltaic panels according to an embodiment of the present invention, as Figures 1-9 shown, the inspection and cleaning system 1 for photovoltaic panels may include: an inspection and cleaning device 10 and a flying device 20. The inspection and cleaning device 10 can travel on the photovoltaic panel. The inspection and cleaning device 10 has a cleaning mechanism 11 and a detection mechanism 12. The cleaning mechanism 11 is used to clean the photovoltaic panel. The detection mechanism 12 is further used to detect the parameter information of the photovoltaic panel and is configured to transmit the parameter information to the control device. The flying device 20 has a damping chain mechanism 21. The inspection and cleaning device 10 also has a clamping mechanism 13. The clamping mechanism 13 is used to clamp or release the damping chain mechanism 21. When the clamping mechanism 13 clamps the damping chain mechanism 21, the flying device 20 can hoist the inspection and cleaning device 10 to the target position. When the clamping mechanism 13 releases the damping chain mechanism 21, the flying device 20 and the inspection and cleaning device 10 can be separated.

[0033] It should be noted that with the rapid development of the domestic new energy industry, the number of photovoltaic power generation devices has increased rapidly. Photovoltaic power stations need to inspect, maintain, and clean photovoltaic panels. Photovoltaic panels are generally laid on the roofs of factories or on photovoltaic brackets and are usually located at high altitudes, which brings great inconvenience to the cleaning, inspection, and maintenance of photovoltaic panels.

[0034] Based on this, an inspection and cleaning system 1 for photovoltaic panels is proposed in an embodiment of the present application. The flying device 20 can be connected to the inspection and cleaning device 10. The flying device 20 can lift the inspection and cleaning device 10 onto the photovoltaic panel. The flying device 20 can be a drone, a remote control plane, etc. The inspection and cleaning device 10 can travel on the photovoltaic panel. The inspection and cleaning device 10 has a cleaning mechanism 11 and a detection mechanism 12. The cleaning mechanism 11 can be used to clean the photovoltaic panel. The cleaning mechanism 11 can include a roller, a brush, etc. The cleaning mechanism 11 can clean the dust on the surface of the photovoltaic panel. The inspection and cleaning system 1 for photovoltaic panels has a control device. The control device can be communicatively connected to the cleaning mechanism 11 and the detection mechanism 12. The detection mechanism 12 can be used to detect the parameter information of the photovoltaic panel. The parameter information can include stain information, damage information, etc. The detection mechanism 12 can transmit the detected parameter information of the photovoltaic panel to the control device. When the detection mechanism 12 detects that there are stains (such as dust, muddy water, etc.) on the photovoltaic panel, the control device can control the cleaning mechanism 11 to work according to the received parameter information. As an example, the detection mechanism 12 can include a camera. The camera can take pictures of the surface of the photovoltaic panel. The camera can transmit the taken images to the control device. The control device can analyze the images to determine whether the photovoltaic panel needs to be cleaned, maintained, etc., so that the control device can selectively control the cleaning mechanism 11 to work.

[0035] As an example, the detection mechanism 12 can detect whether there are impurities or dust on the surface of the photovoltaic panel. If there are impurities or dust on the surface of the photovoltaic panel, the control device drives the cleaning mechanism 11 to clean the photovoltaic panel, reducing the impact of the impurities or dust on the surface of the photovoltaic panel on the power generation efficiency of the photovoltaic panel, thereby effectively improving the power generation efficiency. As another example, the detection mechanism 12 can detect whether the surface of the photovoltaic panel is damaged, etc. The detection mechanism 12 can transmit the detected parameter information of the photovoltaic panel to the control device, so that the damaged photovoltaic panel can be quickly located, which is beneficial to reducing power generation losses.

[0036] The control device can also be communicatively connected to the flying device 20. The control device can drive the flying device 20 to lift the inspection and cleaning device 10 onto the photovoltaic panel. When the parameter information transmitted by the detection mechanism 12 to the control device shows that the photovoltaic panel is working normally, the control device can drive the flying device 20 to fly above the inspection and cleaning device 10 and connect to the inspection and cleaning device 10. The control device can drive the flying device 20 to lift the inspection and cleaning device 10 and move it away from the photovoltaic panel, thereby achieving the effect of recovering the inspection and cleaning device 10.

[0037] The flying device 20 is provided with a damping chain mechanism 21. The damping chain mechanism 21 can be located at the lower part of the flying device 20 and can be used to connect the inspection and cleaning device 10. The inspection and cleaning device 10 is also provided with a clamping mechanism 13. The clamping mechanism 13 can be located at the top end of the inspection and cleaning device 10. The clamping mechanism 13 can be assembled in cooperation with the damping chain mechanism 21. The damping chain mechanism 21 and the clamping mechanism 13 can be docked along the height direction of the inspection and cleaning system 1. The clamping mechanism 13 can clamp or release the damping chain mechanism 21, so as to realize the connection or separation effect between the flying device 20 and the inspection and cleaning device 10. When the inspection and cleaning system 1 is arranged as Figure 1 in the direction, the height direction of the inspection and cleaning system 1 is Figure 1 the Z direction in

[0038] If an ordinary rope is used to connect the flying device 20 and the inspection and cleaning device 10, the ordinary rope is soft and is prone to swing back and forth under the influence of wind during the hoisting process, and the connecting rope is likely to collide with the inspection and cleaning device 10, making it difficult for the flying device 20 to dock with the inspection and cleaning device 10, which affects the reliability of the inspection and cleaning system 1.

[0039] When the damping chain mechanism 21 is connected to the inspection and cleaning device 10 and the flying device 20 hoists the inspection and cleaning device 10 onto the photovoltaic panel, the damping chain mechanism 21 can be straightened and configured as a straight line, and the damping chain mechanism 21 can extend along the height direction of the inspection and cleaning system 1. When the damping chain mechanism 21 is connected to the inspection and cleaning device 10 and the flying device 20 hoists the inspection and cleaning device 10 away from the photovoltaic panel, the damping chain mechanism 21 can be curled up and retracted. Damping has the advantages of reducing vibration and impact and improving smoothness. The damping chain mechanism 21 can resist the wind during the hoisting process, so that the docking between the damping chain mechanism 21 and the clamping mechanism 13 is accurate and stable, reducing the probability of collision between the damping chain mechanism 21 and the inspection and cleaning device 10, reducing the difficulty of transporting the inspection and cleaning device 10 onto the photovoltaic panel, which is beneficial to improving the reliability of the inspection and cleaning system 1 for photovoltaic panels and is beneficial to improving work efficiency.

[0040] In some embodiments of the present invention, as Figure 4 shown, the damping chain mechanism 21 may include: a damping chain 211 and a lifting chuck 212. One end of the damping chain 211 is connected to the lifting chuck 212, and the clamping mechanism 13 is used to clamp or release the lifting chuck 212.

[0041] One end of the damping chain 211 may be connected to the lifting chuck 212. One end of the damping chain 211 may be rotatably connected to the lifting chuck 212. One end of the damping chain 211 may be connected to the lifting chuck 212 by means such as hinged connection or pin connection. The clamping mechanism 13 can clamp or release the lifting chuck 212, so as to achieve the effect that the clamping mechanism 13 clamps or releases the damping chain mechanism 21, and thus achieve the effect of connecting or separating the flying device 20 and the inspection and cleaning device 10.

[0042] In some embodiments of the present invention, as Figure 4 、 Figure 5 、 Figure 8 and Figure 9 shown, the damping chain 211 may include: a plurality of damping chain plates 2111. The plurality of damping chain plates 2111 are sequentially hinged and connected along the length direction of the damping chain 211, and each damping chain plate 2111 is provided with a limiting structure. The limiting structures of any two adjacent damping chain plates 2111 can be in limiting cooperation to limit the relative positions of the two adjacent damping chain plates 2111.

[0043] The damping chain 211 may be composed of a plurality of damping chain plates 2111. Any two adjacent damping chain plates 2111 may be hinged and connected. The plurality of damping chain plates 2111 may be sequentially hinged and connected along the length direction of the damping chain 211. As an example, each damping chain plate 2111 has a first assembly hole 21112. There may be two first assembly holes 21112 for each damping chain plate 2111. The first assembly holes 21112 may penetrate through the corresponding damping chain plate 2111 along the thickness direction of the corresponding damping chain plate 2111. The two first assembly holes 21112 may be oppositely arranged and spaced apart along the length direction of the corresponding damping chain plate 2111. Any two adjacent damping chain plates 2111 may be arranged along the thickness direction of the damping chain plate 2111. The first assembly holes 21112 of any two adjacent damping chain plates 2111 may be oppositely arranged along the thickness direction of the damping chain plate 2111. The first assembly holes 21112 of any two adjacent damping chain plates 2111 are communicated. A connecting shaft may be inserted into the two first assembly holes 21112 that are oppositely arranged in two adjacent damping chain plates 2111. Any two adjacent damping chain plates 2111 may be connected by the connecting shaft, so that any two adjacent damping chain plates 2111 can rotate relative to each other, and the damping chain mechanism 21 can be curled up and retracted.

[0044] As an example, as Figure 5As shown, the lifting chuck 212 can be formed with a second assembly hole 21211. The second assembly hole 21211 and the first assembly hole 21112 of the damping link 2111 adjacent to the lifting chuck 212 can be arranged along the thickness direction of the corresponding damping link 2111. The second assembly hole 21211 and the first assembly hole 21112 of the damping link 2111 adjacent to the lifting chuck 212 can be communicated. The connecting shaft can be inserted into the relatively arranged second assembly hole 21211 and the first assembly hole 21112. The lifting chuck 212 can be connected to the adjacent damping link 2111 through the connecting shaft, so as to achieve the effect of connecting one end of the damping chain 211 to the lifting chuck 212.

[0045] Two damping links 2111 adjacent to the same damping link 2111 can be located on the same side of the damping link 2111 along the thickness direction of the damping link 2111. The orthographic projections of any two adjacent damping links 2111 along the arrangement direction of the two adjacent damping links 2111 (i.e., the thickness direction of the damping link 2111) have an overlapping part, and multiple damping links 2111 are sequentially hinged.

[0046] Each damping link 2111 is provided with a limiting structure. The limiting structures of any two adjacent damping links 2111 can be in limiting cooperation to limit the relative positions of the two adjacent damping links 2111. When the limiting structure of the damping link 2111 is in limiting cooperation with the limiting structure of the adjacent damping link 2111, the damping chain 211 can be straightened. The damping chain 211 can be configured as a straight line. And when the damping chain 211 is straightened and the force on the damping chain 211 is less than the preset pressure value, the relative positions of the two adjacent damping links 2111 are fixed, which can reduce the probability that the damping chain mechanism 21 swings back and forth under the influence of wind when lifting and inspecting and cleaning the device 10, and is beneficial to improving the reliability of the damping chain mechanism 21. When the force on the damping chain 211 is greater than or equal to the preset pressure value, the limiting structures of the two adjacent damping links 2111 no longer cooperate for assembly. When the limiting structure of the damping link 2111 does not cooperate for assembly with the limiting structure of the adjacent damping link 2111, the two adjacent damping links 2111 can rotate relative to each other, and the damping chain 211 can be curled and retracted.

[0047] As an example, the limiting structure of one of any two adjacent damping link pieces 2111 can be a clamping block, and the limiting structure of the other of any two adjacent damping link pieces 2111 can be a clamping groove, and the clamping block can be assembled in cooperation with the clamping groove. When the clamping block is not assembled with the clamping groove, any two adjacent damping link pieces 2111 can rotate relative to each other, and the damping chain 211 can be curled and retracted. When the clamping block is assembled in the adjacent clamping groove, the damping chain 211 can be straightened, and the damping chain 211 can be configured as a straight line. When the force on the damping chain 211 is less than the preset pressure value, the relative positions of any two adjacent damping link pieces 2111 are fixed. When the force on the damping chain 211 is greater than or equal to the preset pressure value, the clamping block can be removed from the corresponding clamping groove, any two adjacent damping link pieces 2111 can rotate relative to each other, and the damping chain 211 can be curled and retracted.

[0048] As an example, the limiting structure on each damping link piece 2111 can be configured as a magnetic attraction structure. When the magnetic attraction structures of any two adjacent damping link pieces 2111 are separated, any two adjacent damping link pieces 2111 can rotate relative to each other, and the damping chain 211 can be curled and retracted. When the magnetic attraction structures of any two adjacent damping link pieces 2111 are attracted to each other, the damping chain 211 can be straightened, and the damping chain 211 can be configured as a straight line. When the force on the damping chain 211 is less than the preset pressure value, the relative positions of any two adjacent damping link pieces 2111 are fixed. When the force on the damping chain 211 is greater than or equal to the preset pressure value, the magnetic attraction structures of any two adjacent damping link pieces 2111 can be separated, any two adjacent damping link pieces 2111 can rotate relative to each other, and the damping chain 211 can be curled and retracted.

[0049] In some embodiments of the present invention, as Figure 4 、 Figure 8 and Figure 9 shown, the limiting structure is configured as a magnet, the damping link piece 2111 is formed with a mounting hole 21111, the limiting structure is mounted in the corresponding mounting hole 21111, and the magnets of any two adjacent damping link pieces 2111 can be attracted to each other.

[0050] The damping link 2111 can be formed with mounting holes 21111, and the mounting holes 21111 can penetrate through the corresponding damping link 2111 along the thickness direction of the damping link 2111. The limiting structure can be configured as a magnet, and the limiting structure can be installed in the corresponding mounting holes 21111. Along the thickness direction of the corresponding damping link 2111, the length dimension of the limiting structure can be equal to the length dimension of the mounting holes 21111 (i.e., the thickness dimension of the damping link 2111). The magnets of any two adjacent damping links 2111 can attract each other, so that the limiting structures of any two adjacent damping links 2111 can be assembled in cooperation, thereby achieving the effect of restricting the relative positions of two adjacent damping links 2111. When the mounting holes 21111 of any two adjacent damping links 2111 are arranged corresponding to each other along the thickness direction of the damping link 2111 and the magnets of any two adjacent damping links 2111 attract each other, the damping chain 211 is straightened, and the damping chain 211 is configured as a straight line. When the force on the damping chain 211 is less than the preset pressure value, the relative positions of two adjacent damping links 2111 are fixed. When the force on the damping chain 211 is greater than or equal to the preset pressure value, the magnets of two adjacent damping links 2111 are separated, and two adjacent damping links 2111 can rotate relative to each other, and the damping chain 211 can be curled and retracted.

[0051] As an example, as Figure 8 and Figure 9 shown, there can be two mounting holes 21111 on each damping link 2111, and the two mounting holes 21111 can be arranged opposite to each other and spaced apart along the length direction of the corresponding damping link 2111. The multiple damping links 2111 can include multiple first damping links 21113 and multiple second damping links 21114. The difference between the first damping link 21113 and the second damping link 21114 lies in the different positions of the mounting holes 21111. The two mounting holes 21111 of the first damping link 21113 can be located outside the two first assembly holes 21112 of the corresponding damping link 2111 along the length direction of the corresponding damping link 2111, and the two mounting holes 21111 of the second damping link 21114 can be located inside the two first assembly holes 21112 of the corresponding damping link 2111 along the length direction of the corresponding damping link 2111. The first damping link 21113 and the second damping link 21114 are hinged. The multiple first damping links 21113 and the multiple second damping links 21114 are arranged in sequence, that is, the damping link 2111 adjacent to the first damping link 21113 is the second damping link 21114, and the damping link 2111 adjacent to the second damping link 21114 is the first damping link 21113. According to the length of the damping chain mechanism 21, an appropriate number of damping links 2111 are selected, and both the first damping link 21113 and the second damping link 21114 can be used to connect to the flight device 20.

[0052] It should be noted that along the length direction of the damping link 2111, the direction close to the center of the damping link 2111 is the inner side, and the direction away from the center of the damping link 2111 is the outer side.

[0053] In some embodiments of the present invention, as Figure 4 and Figure 5 shown, the lifting chuck 212 may include: a connecting frame 2121, a connecting column 2122, and a lifting plate 2123. The connecting column 2122 is connected between the connecting frame 2121 and the lifting plate 2123. The connecting frame 2121 is hingedly connected to the damping chain 211. The cross-sectional area of the lifting plate 2123 is larger than that of the connecting column 2122, and the lifting plate 2123 is configured as a magnetic member so that the lifting plate 2123 can be magnetically coupled with the clamping mechanism 13.

[0054] The connecting frame 2121, the connecting column 2122, and the lifting plate 2123 are connected in sequence. The connecting column 2122 is connected between the connecting frame 2121 and the lifting plate 2123. The connecting column 2122 can extend along the arrangement direction of the connecting frame 2121, the connecting column 2122, and the lifting plate 2123. The connecting column 2122 can be connected to the connecting frame 2121 by welding, bolt connection, etc. The connecting column 2122 can be connected to the lifting plate 2123 by welding, bolt connection, etc. The connecting frame 2121 can be hingedly connected to the damping chain 211. As an example, the connecting frame 2121 can be formed with a second assembly hole 21211 (i.e., the second assembly hole 21211 in the above embodiment). The connecting shaft can be inserted into the second assembly hole 21211 and the first assembly hole 21112 of the damping link 2111 connected thereto in sequence, so as to achieve the effect of connecting one end of the damping chain 211 to the lifting chuck 212. The connecting frame 2121 can be configured as an annular structure with a rectangular longitudinal section, which can reduce the weight of the lifting chuck 212 and reduce the weight borne by the damping chain mechanism 21 when hoisting and inspecting and cleaning the device 10. The connecting frame 2121 is hingedly connected to the damping chain 211, and the connecting frame 2121 can rotate relative to the damping chain mechanism 21. When the flying device 20 uses the damping chain mechanism 21 to hoist and inspect and clean the device 10, the lifting chuck 212 can always extend along the height direction of the inspection and cleaning system 1 under the action of gravity.

[0055] The cross-sectional area of the lifting disc 2123 can be larger than that of the connecting column 2122, and the height dimension of the lifting disc 2123 is smaller than the height dimension of the connecting column 2122, so that the contact area between the lifting chuck 212 and the inspection and cleaning device 10 can be increased, and the stability of the lifting chuck 212 can be improved. The lifting disc 2123 can be connected to the clamping mechanism 13. The clamping mechanism 13 can be made of magnetic metal. The lifting disc 2123 can be configured as a magnetic part, and the lifting disc 2123 can be magnetically coupled with the clamping mechanism 13, so as to connect the lifting chuck 212 and the inspection and cleaning device 10. When the clamping mechanism 13 clamps the lifting chuck 212, the lifting disc 2123 is magnetically coupled with the clamping mechanism 13, so as to further improve the connection strength between the lifting chuck 212 and the inspection and cleaning device 10, which is beneficial to improving the reliability of using the damping chain mechanism 21 to connect the inspection and cleaning device 10 in the inspection and cleaning system 1.

[0056] In some embodiments of the present invention, as Figure 1 , Figure 2 and Figure 9 shown, the flying device 20 further has a drone 22. A rotatable reel 221 is provided below the drone 22. The other end of the damping chain 211 is connected to the reel 221. By rotating the reel 221, the reel 221 can unwind or wind the damping chain 211.

[0057] The flying device 20 further has a drone 22. The drone 22 can be communicatively connected to the control device, and the control device can drive the drone 22 to fly. The drone 22 can be connected with a mounting bracket 222 and a driving motor. The mounting bracket 222 can be fixedly connected to the drone 22 by means of welding, bolt connection, etc. The driving motor can be installed on the side of the mounting bracket 222, and the reel 221 can be installed at the lower part of the mounting bracket 222. Along the extension direction of the reel 221, one end of the reel 221 can be connected to the driving motor, and the other end of the reel 221 away from the driving motor can be installed on the mounting bracket 222 through a bearing. The driving motor has a motor output shaft. The reel 221 can be connected to the motor output shaft through a coupling, a sleeve, etc. The driving motor can drive the motor output shaft to rotate, and the motor output shaft can drive the reel 221 to rotate together, so that the reel 221 can rotate relative to the drone 22. The other end of the damping chain 211 is connected to the reel 221. When the reel 221 rotates, the reel 221 can achieve the effect of unwinding the damping chain 211 or winding the damping chain 211. When the flying device 20 is used to lift the inspection and cleaning device 10 and the damping chain mechanism 21 needs to be straightened, the reel 221 rotates in the first direction to unwind the damping chain 211, and the reel 221 stops rotating after the damping chain 211 is straightened. When it is necessary to retract the inspection and cleaning device 10 and the damping chain mechanism 21 needs to be curled up, the reel 221 rotates in the second direction to wind the damping chain 211.

[0058] It should be noted that the first direction and the second direction are opposite, the first direction is one of the clockwise direction and the counterclockwise direction, and the second direction is the other of the clockwise direction and the counterclockwise direction.

[0059] As an example, the drone 22 may have a landing gear 223. The landing gear 223 can space the fuselage of the drone 22 from the parking surface for parking the drone 22. The fuselage of the drone 22 and the landing gear 223 define a first space. When the flight device 20 is used to recover the inspection and cleaning device 10, the reel 221 rotates to wind the damping chain 211 around the reel 221. The inspection and cleaning device 10 continuously rises and approaches the drone 22. The inspection and cleaning device 10 can rise into the first space, which is beneficial to improving the stability when the flight device 20 drives the inspection and cleaning device 10 to fly, beneficial to reducing the overall volume of the flight device 20 and the inspection and cleaning device 10, and can improve the safety when the flight device 20 drives the inspection and cleaning device 10 to fly.

The clamping mechanism 13, the cleaning mechanism 11 and the detection mechanism 12 are all located on the traveling body 14. The traveling body 14 can travel on the photovoltaic panel, so that the cleaning mechanism 11 and the detection mechanism 12 can move relative to the photovoltaic panel. The clamping mechanism 13 can be provided at the top of the traveling body 14, or the cleaning mechanism 11 and the detection mechanism 12 can be respectively provided at both ends of the traveling body 14 along the traveling direction of the traveling body 14, or the clamping mechanism 13 can be provided at the top of the traveling body 14, and the cleaning mechanism 11 and the detection mechanism 12 can be respectively provided at both ends of the traveling body 14 along the traveling direction of the traveling body 14.

[0062] When the flying device 20 is connected to the inspection and cleaning device 10, the damping chain mechanism 21 is located above the inspection and cleaning device 10, and the clamping mechanism 13 is arranged at the top of the traveling body 14. The clamping mechanism 13 can be arranged on the upper surface of the traveling body 14, so as to facilitate the clamping mechanism 13 to clamp the lifting chuck 212 and also facilitate the magnetic attraction cooperation between the lifting disc 2123 and the clamping mechanism 13. Along the traveling direction of the traveling body 14, the cleaning mechanism 11 and the detection mechanism 12 can be respectively arranged at both ends of the traveling body 14. When the inspection and cleaning device 10 travels on the photovoltaic panel, the detection mechanism 12 can be located at the front end of the traveling body 14, and the cleaning mechanism 11 can be located at the rear end of the traveling body 14. The detection mechanism 12 can transmit the parameter information of the photovoltaic panel detected to the control device, and the control device drives the cleaning mechanism 11 to work according to the parameter information of the photovoltaic panel. As an example, the traveling body 14 can have crawlers, wheels, etc., so that the traveling body 14 can travel on the photovoltaic panel.

The support seat 131 is fixedly arranged on the traveling body 14. The first mounting seat 132 and the second mounting seat 133 are opposite and spaced apart. The first mounting seat 132 and the second mounting seat 133 are both movably arranged on the support seat 131 along the arrangement direction of the first mounting seat 132 and the second mounting seat 133. The plurality of link assemblies 134 are respectively fixedly connected to the first mounting seat 132 and the second mounting seat 133. By moving the first mounting seat 132 and the second mounting seat 133, the plurality of link assemblies 134 are enabled to clamp or release the damping chain mechanism 21.

[0064] The support base 131 can be fixedly arranged on the traveling body 14. The support base 131 can be configured as a plate structure. Four feet 1311 can be installed at the four corners along the circumferential direction of the support base 131. The four feet of the support base 131 can extend along the height direction of the support base 131. When the support base 131 is installed on the traveling body 14, the four feet 1311 of the support base 131 can be connected to the traveling body 14. The first mounting seat 132 and the second mounting seat 133 can be arranged above the support base 131. The first mounting seat 132 and the second mounting seat 133 are arranged oppositely and spaced apart. The first mounting seat 132 and the second mounting seat 133 can both be arranged on the support base 131. The first mounting seat 132 and the second mounting seat 133 can both move along the arrangement direction of the first mounting seat 132 and the second mounting seat 133. As an example, the support base 131 can be formed with two first guiding holes 1312. The first guiding holes 1312 can penetrate the support base 131 along the height direction of the support base 131. The two first guiding holes 1312 can be arranged oppositely and spaced apart along the arrangement direction of the first mounting seat 132 and the second mounting seat 133. The two first guiding holes 1312 can extend along the arrangement direction of the first mounting seat 132 and the second mounting seat 133.

[0065] The clamping mechanism 13 can include a plurality of first sliders 1313. The number of the first sliders 1313 can be two, three, four, etc. In the embodiment of the present application, the case where the first sliders 1313 are two is taken as an example for illustration.

The two first sliders 1313 can be respectively assembled at the two first guiding holes 1312. Each first guiding hole 1312 has a corresponding first slider 1313 in cooperation therewith. The two first sliders 1313 can be respectively fixedly connected to the first mounting seat 132 and the second mounting seat 133. Each first slider 1313 can move at the corresponding first guiding hole 1312, so that the first mounting seat 132 can move relative to the corresponding first guiding hole 1312, and the second mounting seat 133 can move relative to the corresponding first guiding hole 1312, thereby achieving the effect that both the first mounting seat 132 and the second mounting seat 133 are movably arranged on the support base 131 along the arrangement direction of the first mounting seat 132 and the second mounting seat 133.

[0066] The multiple link assemblies 134 can be divided into two parts. The two parts of the link assemblies 134 can be opposite to each other along the arrangement direction of the first mounting seat 132 and the second mounting seat 133. A part of the multiple link assemblies 134 can be fixedly connected to the first mounting seat 132, and another part of the multiple link assemblies 134 can be fixedly connected to the second mounting seat 133.

When the second mounting seat 133 moves, the second mounting seat 133 can drive another part of the multiple link assemblies 134 to move. The multiple link assemblies 134 can cooperate with each other. When the first mounting seat 132 and the second mounting seat 133 approach each other, the multiple link assemblies 134 can clamp the damping chain mechanism 21. When the first mounting seat 132 and the second mounting seat 133 move away from each other, the multiple link assemblies 134 can release the damping chain mechanism 21, so that the multiple link assemblies 134 can clamp or release the damping chain mechanism 21, which is beneficial to improving the connection strength between the flight device 20 and the inspection and cleaning device 10.

[0067] As an embodiment, the plurality of link assemblies 134 may include a first link, a second link, a third link, and a fourth link.

The second link and the third link may be located on the same side of the first mounting seat 132 and the second mounting seat 133. The third shaft body may pass through the second link and the third link, so that the second link and the third link may be rotatably connected. An included angle is formed between the second link and the third link, and the included angle may be an acute angle. The first link and the fourth link may be located on the other side of the first mounting seat 132 and the second mounting seat 133. The fourth shaft body may pass through the first link and the fourth link, so that the first link and the fourth link may be rotatably connected. An included angle is formed between the first link and the fourth link, and the included angle may be an acute angle. When the first mounting seat 132 and the second mounting seat 133 approach each other, the first link, the second link, the third link, and the fourth link rotate relative to each other, and the clamping mechanism 13 may clamp the damper chain mechanism 21. When the first mounting seat 132 and the second mounting seat 133 move away from each other, the first link, the second link, the third link, and the fourth link rotate relative to each other, and the clamping mechanism 13 may release the damper chain mechanism 21.

[0068] In some embodiments of the present invention, as Figure 5 shown, the inspection and cleaning system 1 for a photovoltaic panel may further include: a plurality of shaft bodies 135. There are two link assemblies 134. The two link assemblies 134 are arranged along the arrangement direction of the first mounting seat 132 and the second mounting seat 133. The two link assemblies 134 are respectively fixed to the first mounting seat 132 and the second mounting seat 133 through a plurality of shaft bodies 135. Each link assembly 134 includes a first clamping link 1341 and a second clamping link 1342 that are cross - arranged.

[0069] There may be two connecting rod assemblies 134, and the two connecting rod assemblies 134 can be respectively installed on the first mounting seat 132 and the second mounting seat 133. The two connecting rod assemblies 134 are arranged along the arrangement direction of the first mounting seat 132 and the second mounting seat 133. One of the connecting rod assemblies 134 can be fixedly arranged on the first mounting seat 132 through a plurality of shaft bodies 135, and the other connecting rod assembly 134 can be fixedly arranged on the second mounting seat 133 through a plurality of shaft bodies 135. Each connecting rod assembly 134 includes a first clamping connecting rod 1341 and a second clamping connecting rod 1342.

When the first mounting seat 132 and the second mounting seat 133 approach each other, the two connecting rod assemblies 134 approach each other. When both of the two connecting rod assemblies 134 are in contact with the connecting column 2122, the clamping mechanism 13 clamps the lifting chuck 212. When the first mounting seat 132 and the second mounting seat 133 move away from each other, the two connecting rod assemblies 134 move away from each other, the clamping mechanism 13 releases the lifting chuck 212, and the lifting chuck 212 can move upward and separate from the support seat 131. And when the distance between the two connecting rod assemblies 134 is greater than the length dimension of the connecting frame 2121 along the arrangement direction of the first mounting seat 132 and the second mounting seat 133, the risk of collision between the lifting chuck 212 and the connecting rod assembly 134 can be reduced.

[0071] The inspection and cleaning device 10 further includes a plurality of driving mechanisms 15. Along the height direction of the inspection and cleaning device 10, the plurality of driving mechanisms 15 can be disposed on the side of the clamping mechanism 13 away from the damping chain mechanism 21, that is, the plurality of driving mechanisms 15 can be disposed on the lower surface of the support base 131 along the height direction of the inspection and cleaning device 10. A part of the plurality of driving mechanisms 15 can be in transmission connection with the first mounting seat 132, and a part of the plurality of driving mechanisms 15 can be used to drive the first mounting seat 132 to move.

In this application, two driving mechanisms 15 are taken as an example for illustration. One driving mechanism 15 is in transmission connection with the first mounting seat 132 to drive the first mounting seat 132 to move, and the other driving mechanism 15 is in transmission connection with the second mounting seat 133 to drive the second mounting seat 133 to move.

[0072] As an example, as Figure 6 shown, racks 17 can be provided on the surface of the support base 131 that faces away from the first mounting seat 132 and the second mounting seat 133 along the height direction of the inspection and cleaning device 10, that is, racks 17 can be provided on the lower surface of the support base 131 along the height direction of the inspection and cleaning device 10. The racks 17 and the two driving mechanisms 15 are disposed on the same side of the support base 131. There can be two racks 17, and the two racks 17 can extend along the arrangement direction of the first mounting seat 132 and the second mounting seat 133.

[0074] The first output shaft can be connected with a gear 16. The gear 16 can mesh with a rack 17 and can rotate relative to the rack 17. The first output shaft can be fixedly connected with the gear 16 through a flat key, a locking member, etc. The driving motor can drive the first output shaft to rotate. When the driving motor drives the first output shaft to rotate, the first output shaft can drive the gear 16 to rotate. The gear 16 can rotate relative to the rack 17, so as to drive the corresponding driving mechanism 15 to move along the arrangement direction of the first mounting seat 132 and the second mounting seat 133. When the first driving mechanism 151 moves relative to the corresponding rack 17, the first driving mechanism 151 drives the first mounting seat 132 to move along the arrangement direction of the first mounting seat 132 and the second mounting seat 133. When the second driving mechanism 152 moves relative to the corresponding rack 17, the second driving mechanism 152 drives the second mounting seat 133 to move along the arrangement direction of the first mounting seat 132 and the second mounting seat 133.

[0075] As an example, a guiding structure 136 can also be provided on the surface of the support seat 131 facing away from the first mounting seat 132 and the second mounting seat 133 along the height direction of the inspection and cleaning device 10, that is, the guiding structure 136 can be provided on the lower surface of the support seat 131 along the height direction of the inspection and cleaning device 10.

[0076] In the embodiment of this application, when it is necessary to clean and inspect the photovoltaic panel, the control device drives the driving motor on the unmanned aerial vehicle 22 to work. The driving motor drives the reel 221 to rotate so as to unwind the damping chain 211. The damping chain 211 is straightened, and the limiting structures of the multiple damping chain pieces 2111 cooperate with each other. The control device drives the flying device 20 to fly above the inspection and cleaning device 10. The lifting disk 2123 and the support seat 131 are magnetically attracted and matched.

[0077] After the inspection and cleaning device 10 lands on the photovoltaic panel, the control device drives the first driving mechanism 151 and the second driving mechanism 152 to work. The first driving mechanism 151 drives the first mounting seat 132 to move, and the second driving mechanism 152 drives the second mounting seat 133 to move. The first mounting seat 132 and the second mounting seat 133 move away from each other, and the clamping mechanism 13 releases the lifting chuck 212. The flying device 20 moves upward so that the lifting disc 2123 is separated from the support seat 131. The detection mechanism 12 detects the parameter information of the photovoltaic panel. The detection mechanism 12 transmits the parameter information of the photovoltaic panel to the control device. The control device determines whether there is impurity or dust on the surface of the photovoltaic panel according to the parameter information of the photovoltaic panel, and the control device determines whether the surface of the photovoltaic panel is damaged according to the parameter information of the photovoltaic panel. If there is dust on the surface of the photovoltaic panel, the control device drives the cleaning mechanism 11 to work.

[0078] When the inspection and cleaning of the photovoltaic panel are completed, the flying device 20 flies above the inspection and cleaning device 10. At this time, the lifting disc 2123 and the support seat 131 are magnetically attracted to each other, and the damping chain 211 is straightened.

The first driving mechanism 151 drives the first mounting seat 132 to move, and the second driving mechanism 152 drives the second mounting seat 133 to move. The first mounting seat 132 and the second mounting seat 133 move closer to each other, and the clamping mechanism 13 clamps the lifting chuck 212. The control device drives the driving motor on the drone 22 to work. The driving motor drives the reel 221 to rotate so that the reel 221 winds the damping chain 211, so that the force on the damping chain 211 is greater than or equal to the preset pressure value, and the magnets of adjacent two damping chain pieces 2111 are separated, and adjacent two damping chain pieces 2111 rotate relatively, and the damping chain 211 curls and retracts. The inspection and cleaning device 10 continuously rises. When the inspection and cleaning device 10 rises to the first space, the flying device 20 retrieves the inspection and cleaning device 10.
