[0024] EMBODIMENT

[0025] REFERENCE Figures 1-4 For the first embodiment of the utility model, a photovoltaic cleaning robot is provided, which comprises a frame unit 100, a driving unit 200 and a cleaning unit 300, the frame unit 100 is connected with an anti-skid unit 400, the anti-skid unit 400 comprises an anti-skid piece 401 and a connecting piece 402, the anti-skid piece 401 is connected with the cross frame 101 through the connecting piece 402, and the anti-skid piece 401 is arranged above the photovoltaic panel and used for identifying whether the driving wheel 201 slips.

[0026] Specifically, for the hanging rail type photovoltaic cleaning robot, it is inclined on the photovoltaic panel when in use, the machine moves linearly under the driving of the driving motor, the frame unit 100 is the basic frame of the cleaning robot, driving units 200 are arranged at both ends of the frame unit 100 for providing driving power, including providing power for the roller brush, the driving wheel and the driving wheel, the cleaning unit 300 includes devices such as the roller brush and the scraping strip, and it should be noted that the frame unit 100 and the cleaning unit 300 are prior art, and an anti-skid unit 400 is arranged below the frame unit 100, the anti-skid unit 400 is mainly aimed at the slip of the driving wheel 201, that is, when the driving wheel 201 slips when walking on the photovoltaic panel, it can be timely identified, the anti-skid unit 400 includes an anti-skid piece 401 and a connecting piece 402, wherein the connecting piece 402 mainly plays a connecting role, that is, the anti-skid piece 401 is connected with the frame unit 100 through the connecting piece 402, as shown in Figure 1 and 2 In actual use, the anti-skid piece 401 is arranged between the photovoltaic panel and the cleaning unit 300, that is, the anti-skid piece 401 is above the photovoltaic panel, which can identify the state of the driving wheel 201, when the driving wheel 201 slips and idles on the photovoltaic panel, the anti-skid piece 401 can timely find it out, and then feedback the relevant information for processing.

[0027] The anti-skid piece 401 includes an anti-skid wheel 401a arranged in parallel with the driving wheel 201 and a rotating plate 401b coaxially arranged with the anti-skid wheel 401a, the rotating plate 401b is provided with a rotating slot 401c, and one side of the rotating plate 401b is provided with a sensor 401d for identifying the rotation of the rotating plate 401b.

[0028] For the anti-skid piece 401, as Figure 2 and Figure 3As shown, the anti-skid piece 401 includes an anti-skid wheel 401a and a rotating plate 401b, which are connected by a shaft, that is, when the anti-skid wheel 401a rotates, the rotating plate 401b will rotate synchronously, when the driving wheel 201 slips or stops at a certain place, the anti-skid wheel 401a will also stop or idle at the same place, and the rotating plate 401b will synchronously display the rotating state of the anti-skid wheel 401a. A rotating slot 401c is formed on the rotating plate 401b, which will rotate when the rotating plate 401b rotates. The sensor 401d can identify the state of the rotating slot 401c in real time and further obtain the states of the rotating plate 401b and the anti-skid wheel 401a, and determine the motion state of the photovoltaic cleaning device. Further, the rotating slots 401c are arranged at equal intervals and the number is not less than 4. This is mainly based on that when the rotating plate 401b rotates, the rotating slot 401c will also rotate, and the sensor 401d will emit different signals when the signals meet the body and gap of the rotating slot 401c. That is, setting a certain number of rotating slots 401c can ensure that the state of the rotating plate 401b is identified more timely and accurately, and the sensor 401d can identify the information at the first time when the anti-skid wheel 401a slips or idles.

[0029] The connecting piece 402 and the anti-skid piece 401 are connected by a rotating shaft 402a, one end of the rotating shaft 402a is arranged perpendicularly to the anti-skid wheel 401a, and the other end of the rotating shaft 402a is connected perpendicularly to the connecting plate 402b.

[0030] In addition, for the fixed installation of the anti-skid piece 401, Figure 3 and Figure 4As shown, the connecting piece 402 and the anti-skid piece 401 are connected through a rotating shaft 402a, the rotating shaft 402a is connected perpendicularly on the side close to the anti-skid wheel 401a, and is connected with a connecting plate 402b on the other side, the connecting piece 402 is mainly used for connecting the anti-skid piece 401, it should be noted that in order to prevent the anti-skid wheel 401a from being attached to the surface of the photovoltaic panel, an action force in the direction of the photovoltaic panel needs to be applied to the anti-skid wheel 401a, so as to ensure that the anti-skid wheel 401a can rotate on the photovoltaic panel, and cannot rotate due to suspension or insufficient friction with the panel, as shown, a connecting hole 402d is arranged on the connecting plate 402b, one end of a spring 402c is connected through the connecting hole 402d, and the other end is connected to the horizontal frame 101, specifically, for the two ends of the spring 402c, on the end connected with the horizontal frame 101, the connecting plate 402b is perpendicularly arranged with an extension rod 402e on the side away from the rotating shaft 402a, the extension rod 402e is perpendicularly connected with the connecting plate 402b in the upper part, and a fixed plate 402f at the end of the extension rod 402e is detachably connected with the horizontal frame 101, the connection between the spring 402c and the horizontal frame 101 refers to the connection between one end of the spring 402c and the fixed plate 402f, due to the existence of the extension rod 402e, it can be seen that the spring 402c is arranged obliquely, and can apply an action force to the connecting plate 402b in the direction of the photovoltaic panel, therefore, the anti-skid piece 401 is connected with the connecting plate 402b, and thus the anti-skid piece 401 will also be subjected to an action force in the direction of the photovoltaic panel, so as to ensure that the anti-skid wheel 401a is attached to the surface of the photovoltaic panel.

[0031] In order to place the sensor 40d, a supporting piece 403 is connected to the inner side of the connecting plate 402b, the supporting piece 403 and the connecting plate 402b are connected through screws or bolts, as shown in Figure 3 and Figure 4 As shown, the supporting piece 403 is L-shaped, and the sensor 401d is connected to the supporting piece 403, and can identify whether the rotating plate 401b rotates normally.
