[0061] Optionally, as shown in Figure 4 The connecting rod 3 comprises a connecting head 32 and a rod body 31 connected with each other, the rod body 31 is connected with the driving member 4, and the connecting head 32 is inserted into the second sliding groove 22 and is horizontally movable and rotatable relative to the second sliding groove 22.

[0062] In the optional embodiment, the rod body 31 is connected with the driving member 4, the driving member 4 can drive the rod body 31 to rotate relative to the curtain wall body 1, so that the movable connection between the rod body 31 and the curtain wall body 1 is a rotation pair, the connecting head 32 is inserted into the second sliding groove 22 and is horizontally movable and rotatable relative to the second sliding groove 22, so that the movable connection between the connecting head 32 and the moving block 2 is a higher pair, and the moving block 2 is movably mounted on the curtain wall body 1 in a vertical direction, so that the movable connection between the moving block 2 and the curtain wall body 1 is a movement pair. Therefore, the curtain wall body 1, the connecting rod 3 and the moving block 2 form a sinusoidal mechanism with a higher pair, the driving member 4 can smoothly drive the moving block 2 to move up and down by driving the connecting rod 3 to rotate, and the number of components is small, so as to reduce the weight of the whole curtain wall while ensuring the cleaning function.

[0064] Specifically, the connecting head 32 can be in a cylindrical shape, and the third groove 321 can be annularly arranged on the circumferential surface of the connecting head 32.

[0065] In the optional embodiment, the mutual cooperation between the second protruding rib 221 and the third groove 321 can ensure that the horizontal movement of the connecting head 32 is not easy to deviate, and at the same time, the connecting head 32 can be limited to prevent the connecting head 32 from being pulled out of the second sliding groove 22.

[0067] It can be understood that the cleaning member 21 can cooperate with rainwater to clean the photovoltaic module 5 on rainy days. Specifically, first, rainwater falls on the surface of the photovoltaic module 5, and then the cleaning member 21 moves upwards from bottom to top to clean the surface of the photovoltaic module 5 and generates sewage.

[0068] In the optional embodiment, because the water storage tank 23 is located below the cleaning member 21 and the slot of the water storage tank 23 is arranged towards the cleaning member 21, the sewage generated after the cleaning member 21 sweeps the photovoltaic module 5 can flow into the water storage tank 23 to be collected in the water storage tank 23, so as to avoid the sewage from flowing randomly to repeatedly contaminate the surface of the cleaned photovoltaic module 5.

[0069] Optionally, as shown in Figure 1 , Figure 7 , Figure 8 illustrated, the height of the driving member 4 is lower than the height of the upper end of the first chute 14; the connecting rod 3 further comprises a cavity penetrating the rod body 31 and the connecting head 32 in sequence, and the cavity penetrates the outer wall of the connecting head 32 to form a water inlet 322; the inner wall of the second chute 22 is provided with a drainage head 222 communicating with the water storage tank 23, and the drainage head 222 is arranged to be openable and closable; when the driving member 4 drives the moving block 2 to move to the upper end of the first chute 14, the water inlet 322 is aligned with the drainage head 222.

[0070] In the optional embodiment, when the driving member 4 drives the moving block 2 to move to the upper end of the first chute 14, the water inlet 322 of the connecting head 32 is aligned with the drainage head 222, at this time, the drainage head 222 can be opened to communicate with the water inlet 322, and because the height of the driving member 4 is lower than the height of the upper end of the first chute 14, at this time, the sewage collected in the water storage tank 23 can flow into the cavity of the connecting rod 3 through the drainage head 222 and the water inlet 322 under the action of gravity, so as to realize the drainage of the sewage in the water storage tank 23, which is beneficial to the repeated collection of water in the water storage tank 23.

[0071] It should be noted that in the actual cleaning process, the moving block 2 at the upper end of the first chute 14 can be controlled to stop for a period of time by the driving member 4 to ensure that the sewage in the water storage tank 23 flows out sufficiently.

[0072] Optionally, as shown in Figure 9 and Figure 10 illustrated, the drainage head 222 is provided with a valve piece 223, the valve piece 223 is provided with a crack 2231, and the valve piece 223 is used to open the crack 2231 when the valve piece 223 is deformed and close the crack 2231 when the valve piece 223 restores the deformation.

[0073] Specifically, the material of the valve piece 223 can be a flexible material, which can automatically restore the deformation after being deformed under force.

[0074] In the optional embodiment, the valve piece 223 can open the crack 2231 when the valve piece 223 is deformed to open the drainage head 222, and close the crack 2231 when the valve piece 223 restores the deformation to close the drainage head 222, so as to realize the openable and closable arrangement of the drainage head 222, and the valve piece 223 has a simple structure, which is beneficial to simplify the structure of the drainage head 222.

[0075] Optionally, as shown in Figure 8 and Figure 10 , the valve piece 223 is provided with a first magnetic attraction part 2232; the water inlet 322 is provided with a second magnetic attraction part 3221, the second magnetic attraction part 3221 is used to be magnetically attracted with the first magnetic attraction part 2232 when the water inlet 322 is aligned with the drain head 222, so as to drive the valve piece 223 to deform and open the crack 2231.

[0076] Specifically, as shown in Figure 10 , the crack 2231 can be cross-shaped, and the valve piece 223 can be provided with four first magnetic attraction parts 2232, which can be respectively arranged on the four parts of the valve piece 223 divided by the cross-shaped crack, and correspondingly, as shown in Figure 11 and Figure 12 , the water inlet 322 can be provided with four second magnetic attraction parts 3221, so that the four first magnetic attraction parts 2232 and the four second magnetic attraction parts 3221 are correspondingly magnetically attracted, which can make the four parts of the valve piece 223 deform synchronously to quickly open the drain head 222.

[0077] In this optional embodiment, the valve piece 223 is driven to deform by the mutual magnetic attraction of the first magnetic attraction part 2232 and the second magnetic attraction part 3221 to automatically open the crack 2231, so as to open the drain head 222, and when the first magnetic attraction part 2232 and the second magnetic attraction part 3221 are separated from each other, the valve piece 223 can automatically restore the deformation to close the crack 2231, so as to close the drain head 222, thereby realizing the automatic opening and closing of the drain head 222.

[0078] Optionally, as shown in Figure 4 and Figure 7 , the outer wall of the connecting head 32 is provided with a guide groove 323 in communication with the water inlet 322; the drain head 222 protrudes from the inner wall of the second sliding groove 22, and the drain head 222 is used to enter the water inlet 322 along the guide groove 323 when the connecting head 32 moves along the second sliding groove 22.

[0079] It should be noted that when the connecting head 32 moves along the second sliding groove 22, since the entire connecting rod 3 rotates under the driving of the driving part 4, the movement path of the connecting head 32 relative to the curtain wall body 1 is also an arc path, so the width of the guide groove 323 can be greater than the outer diameter of the drain head 222, thereby avoiding the interference between the guide groove 323 and the drain head 222 when the guide groove 323 moves along the arc path.

[0080] In the alternative embodiment, the protrusion of the drain head 222 from the inner wall of the second chute 22 can make the drain head 222 closer to the water inlet 322, which is conducive to reducing the gap between the drain head 222 and the water inlet 322 and preventing sewage leakage. In addition, the guide groove 323 can avoid the drain head 222, and when the connecting head 32 moves along the second chute 22, the drain head 222 can enter the water inlet 322 along the guide groove 323 to prevent the drain head 222 from colliding with the outer wall of the connecting head 32.

[0081] Optionally, as shown in Figure 1 the distance between the driving member 4 and the upper end of the first chute 14 is greater than the distance between the driving member 4 and the lower end of the first chute 14.

[0082] In the alternative embodiment, the above arrangement can make the driving member 4 closer to the lower end of the first chute 14, so that when the moving block 2 moves to the lower end of the first chute 14, the connecting head 32 will not contact the drain head 222, which not only avoids interference and collision between the connecting head 32 and the drain head 222, but also prevents the sewage in the water storage groove 23 from accidentally flowing out.

[0083] Optionally, as shown in Figure 13 the cavity penetrates the end of the rod body 31 connected with the driving member 4 to form a water outlet 311.

[0084] In the alternative embodiment, the water outlet 311 can discharge the sewage received by the cavity out of the connecting rod 3, which realizes effective discharge of sewage and prevents repeated pollution of the photovoltaic module 5 by sewage generated during cleaning.

[0085] Optionally, as shown in Figure 14 the water outlet 311 is connected with a water outlet pipe 312.

[0086] In the alternative embodiment, the water outlet pipe 312 can effectively guide the sewage flowing out of the water outlet 311, preventing the sewage from splashing onto the photovoltaic module 5 due to direct flow out of the water outlet 311.

[0087] Optionally, as shown in Figure 14 the curtain wall body 1 is provided with an upper and lower extending flow guide groove 15; and the free end of the water outlet pipe 312 is arranged in the flow guide groove 15.

[0088] In the alternative embodiment, the flow guide groove 15 can guide the sewage downward along the curtain wall body 1 to avoid the sewage stagnating on the curtain wall body 1, thereby reducing the erosion of the photovoltaic curtain wall.

[0089] Although the present disclosure discloses as above, the protection scope of the present disclosure is not limited to this. The person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present disclosure, and these changes and modifications will fall within the protection scope of the present disclosure.
