[0042] The following exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. If there are several specific embodiments, the features of these embodiments can be combined with each other without conflict. When the description refers to the drawings, unless otherwise specified, the same numbers in different drawings represent the same or similar elements. The contents described in the following exemplary embodiments do not represent all embodiments consistent with the present invention; rather, they are merely examples of devices, products and / or methods that are consistent with some aspects of the present invention and are described in the claims of the present invention.

[0043] The terms used in this utility model are only for the purpose of describing specific embodiments and are not intended to limit the scope of protection of this utility model. The singular forms "a", "the" or "the" used in the specification and claims of this utility model are also intended to include the plural forms, unless the context clearly indicates otherwise.

[0044] Please refer to Figures 1 to 9 The utility model discloses a photovoltaic cleaning robot 200 for cleaning photovoltaic modules 300. The photovoltaic cleaning robot 200 includes a main body, a driving device and a protective structure 100. The driving device is arranged at one end of the main body in the length direction. The driving device extends out of the edge of the photovoltaic module 300 in the width direction of the photovoltaic module 300. The driving device drives the main body to move along the arrangement direction of the photovoltaic module 300. The protective structure 100 is arranged at the bottom of the driving device along the height direction. For the convenience of explanation, the width direction of this application is the first direction D1-D1, the length direction is the second direction D2-D2, and the height direction is the third direction D3-D3. The first direction D1-D1, the second direction D2-D2 and the third direction D3-D3 are perpendicular to each other. The protective structure 100 includes a protective cover 1, a rotating shaft 2, an anti-slip component 3 and at least one elastic element 4. One end of the protective cover 1 is arranged at the bottom of the driving device, the rotating shaft 2 is passed through the other end of the protective cover 1, the anti-slip component 3 is pivotally arranged on the rotating shaft 2 and can rotate around the rotating shaft 2, at least one elastic element 4 is sleeved on the rotating shaft 2, one end of the elastic element 4 elastically abuts against the protective cover 1, and the other end of the elastic element 4 elastically abuts against the anti-slip component 3. Figure 9As shown, when the photovoltaic cleaning robot 200 is gradually placed on the photovoltaic assembly 300, the anti-slip assembly 3 first abuts against the edge of the photovoltaic assembly 300. The anti-slip assembly 3 is subjected to the reaction force of the abutment of the edge of the photovoltaic assembly 300 and rotates toward the protective cover 1, and the elastic element 4 is compressed to store energy. After the photovoltaic cleaning robot 200 is placed on the photovoltaic assembly 300, the anti-slip assembly 3 is separated from the edge of the photovoltaic assembly 300, and the elastic element 4 releases the stored energy to drive the anti-slip assembly 3 to rotate to the side away from the protective cover 1. At this time, the photovoltaic assembly 300 is located between the anti-slip assembly 3 and the body. In this way, the damage to the photovoltaic assembly 300 caused by the collision between the protective structure 100 and the photovoltaic assembly 300 can be reduced, thereby reducing maintenance costs.

[0045] Please refer to Figures 1 to 2 In this embodiment, the anti-slip assembly 3 has a first position and a second position. When the anti-slip assembly 3 is in the first position, the anti-slip assembly 3 is perpendicular to the protective cover 1. When the anti-slip assembly 3 is in the second position, the anti-slip assembly 3 is close to the protective cover 1 and folded. In other embodiments, the first position and the second position of the anti-slip assembly 3 can also be adjusted as needed to adapt to different installation scenarios.

[0046] Please refer to Figures 3 and 4 The protective cover 1 has a "C"-shaped structure and includes a first base 11, a second base 12, and a third base 13. The first base 11 extends along the thickness direction of the photovoltaic cleaning robot 200. The second base 12 and the third base 13 are respectively arranged at the upper and lower ends of the first base 11. The second base 12 and the third base 13 are located on the same side of the first base 11 and are parallel to each other. The second base 12 and the third base 13 extend along the second direction, and the second base 12 is fixedly connected to the driving device by screws. A first through hole 101 is provided on the first base 11 near the third base 13. The rotating shaft 2 passes through the two first through holes 101 to allow the anti-slip component 3 to rotate between the third base 13 and the first base 11. This can limit the anti-slip component 3 from rotating too much.

[0047] Please refer to Figure 3 The first base 11 also includes two wings 14, which are respectively arranged vertically on the same two sides of the width direction of the first base 11. Each wing 14 is provided with a first through hole 101. The two first through holes 101 are symmetrically arranged in the width direction of the first base 11. The rotating shaft 2 passes through the two first through holes 101, so that the anti-slip component 3 can rotate between the third base 13 and the first base 11, and at the same time facilitates the installation of the rotating shaft 2 and improves the installation efficiency.

[0048] The wing portion 14 includes a first end 141 and a second end 142 opposite each other. The first end 141 contacts the top wall of the third base portion 13, and the area of ​​the wing portion 14 gradually decreases from the first end 141 to the second end 142. Preferably, the first through hole 101 is provided at the first end 141, which can improve the stability of the anti-slip assembly 3 during rotation and prevent shaking during rotation.

[0049] Please refer to Figures 5 to 7 The anti-slip assembly 3 includes a connector 31 and an anti-slip hook 32. The connector 31 is arranged in the space enclosed by the two wings 14. One end of the connector 31 is pivotally connected to the rotating shaft 2, and the anti-slip hook 32 is connected to the other end of the connector 31 by a fastener 7. Specifically, the connector 31 includes a first connector 311, two second connectors 312 perpendicularly arranged on both sides of the first connector 311 in the first direction D1-D1, and a third connector 313 arranged between the two second connectors 312. The two second connectors 312 extend toward one side of the base. The first connector 311, the two second connectors 312, and the third connector 313 are interconnected to form a receiving space 303. Each second connector 312 has a second through hole 301. The rotating shaft 2 passes through the two second through holes 301. The other end of the elastic element 4 is located in the receiving space 303, and the other end of the elastic element 4 abuts against the top spring pad of the third connector 313. The anti-detachment hook 32 and the second connecting part 312 are arranged opposite to each other relative to the first connecting part 311. The first connecting part 311 has a third through hole. The fastener 7 passes through the third through hole and is connected to the anti-detachment hook 32, so that the anti-detachment hook 32 can rotate relative to the first connecting part 311 or the anti-detachment hook 32 is fixed relative to the first connecting part 311. The structure is simple, easy to install, and easy to maintain.

[0050] The wing portion 14 is further provided with a first positioning hole 102, and the second connecting portion 312 is provided with a second positioning hole 302. The anti-slip assembly 3 also includes a positioning pin 6. When the anti-slip assembly 3 is in the second position, the positioning pin 6 sequentially passes through the first positioning hole 102 and the second positioning hole 302 to secure the anti-slip assembly 3 in the second position. This facilitates the subsequent removal of the photovoltaic cleaning robot 200 from the photovoltaic assembly 300 and prevents the anti-slip hook 32 from colliding with the back of the photovoltaic assembly 300 and causing damage to the photovoltaic assembly 300.

[0051] Please refer to Figures 5 and 6 as well as Figure 8The protective structure 100 also includes a sleeve 5, which is arranged in the space enclosed by the two wings 14. The rotating shaft 2 passes through the sleeve 5. The elastic element 4 includes two elastic elements 4, and the two elastic elements 4 are respectively arranged on both sides of the sleeve 5. The sleeve 5 is arranged between the two elastic elements 4 to avoid the two elastic elements 4 from touching each other during compression or rebound, thereby affecting the continuity and stability of the rotation of the anti-slip component 3. At the same time, by providing two elastic elements 4, it is also possible to avoid the anti-slip component 3 from offsetting during the rotation process, thereby causing the rotation position of the anti-slip component 3 to change and making it impossible to maintain the positions of the photovoltaic cleaning robot 200 and the photovoltaic component 300 within the normal range.

[0052] Please refer to Figures 5 to 8 The elastic element 4 includes an elastic portion 41, a first contact portion 42, and a second contact portion 43. The elastic element 4 is a torsion spring. The first contact portion 42 and the second contact portion 43 form an angle. The rotating shaft 2 passes through the elastic portion 41. The first contact portion 42 elastically abuts against the first base portion 11, and the second contact portion 43 elastically abuts against the third connecting portion 313. When the anti-slip assembly 3 rotates from the first position to the second position, the third connecting portion 313 drives the second contact portion 43 closer to the first contact portion 42, so that the elastic element 4 can be compressed to store energy. Preferably, using a torsion spring as the elastic element 4 can reduce installation costs and improve installation efficiency.

[0053] In summary, the present invention discloses a photovoltaic cleaning robot 200 for cleaning photovoltaic modules 300. The photovoltaic cleaning robot 200 includes a main body, a drive device, and a protective structure 100. The protective structure 100 includes a protective cover 1, a rotating shaft 2, an anti-slip assembly 3, and at least one elastic element 4. One end of the protective cover 1 is set at the bottom of the drive device, the rotating shaft 2 is passed through the other end of the protective cover 1, the anti-slip assembly 3 is pivotally set on the rotating shaft 2, and at least one elastic element 4 is sleeved on the rotating shaft 2. One end of the elastic element 4 elastically abuts against the protective cover 1, and the other end of the elastic element 4 elastically abuts against the anti-slip assembly 3. When the photovoltaic cleaning robot 200 is gradually placed on the photovoltaic module 300, the anti-slip component 3 first abuts against the edge of the photovoltaic module 300. The anti-slip component 3 is then subjected to the reaction force of the abutment of the edge of the photovoltaic module 300 and rotates toward the protective cover 1. The elastic element 4 is compressed to store energy. After the photovoltaic cleaning robot 200 is placed on the photovoltaic module 300, the anti-slip component 3 separates from the edge of the photovoltaic module 300, and the elastic element 4 releases the stored energy, driving the anti-slip component 3 to rotate away from the protective cover 1. This allows the protective cover 1 to prevent the anti-slip component 3 from colliding with the photovoltaic module 300 during the handling process of the photovoltaic cleaning robot 200, thereby reducing damage to the photovoltaic module 300 and lowering maintenance costs.
