[0041] Please refer to Figures 1 to 7The utility model discloses a photovoltaic system, which includes a photovoltaic support, a photovoltaic module 200, a photovoltaic cleaning device 100 and a control center. The photovoltaic cleaning device 100 is used to clean the photovoltaic module, and the photovoltaic module includes a first photovoltaic module 210 and a second photovoltaic module 220 located in the same row. The first photovoltaic module 210 and the second photovoltaic module 220 are respectively installed on two adjacent photovoltaic supports in a straight line direction. The first photovoltaic module 210 and the second photovoltaic module 220 are arranged in sequence along the traveling direction of the photovoltaic cleaning device 100, and a bridge mechanism 300 is provided between the first photovoltaic module 210 and the second photovoltaic module 220. The photovoltaic support can be a photovoltaic tracking support or a photovoltaic fixed or fixed adjustable support. When the photovoltaic support is a tracking support, the first photovoltaic assembly 210 and the second photovoltaic assembly 220 rotate differently under the drive of their respective driving mechanisms, so that there is an angle difference between the first photovoltaic assembly 210 and the second photovoltaic assembly 220. When the photovoltaic support is a fixed support, the first photovoltaic assembly 210 and the second photovoltaic assembly 220 are mutually misaligned on their respective photovoltaic supports, and then there is a first angle a between the bridge mechanism 300 and the first photovoltaic assembly 210. The first angle a is the angle between the bridge mechanism 300 and the horizontal plane where the first photovoltaic assembly 210 is located. Only when the first angle a is within the set range can the photovoltaic cleaning device 100 pass through the bridge mechanism 300 smoothly. When the first angle a exceeds the set angle range, the photovoltaic cleaning device 100 will be stuck. For example, when the photovoltaic support is a fixed support, the angle range of the first angle a between the bridge mechanism 300 and the first photovoltaic assembly 210 is 10°, and the photovoltaic cleaning device 100 can pass through the slope angle of 20°, then the photovoltaic cleaning device 100 can smoothly pass through the bridge mechanism 300. Similarly, when the photovoltaic support is a tracking support, as long as the first angle between the bridge mechanism 300 and the first photovoltaic assembly 210 is smaller than the slope angle that the photovoltaic cleaning device 100 can pass through, the photovoltaic cleaning device 100 can smoothly pass through the bridge mechanism 300.

[0042] Please refer to Figures 1 to 7The photovoltaic cleaning device 100 includes a photovoltaic cleaning mechanism 1, a controller and a sensor 2. The controller is installed on the photovoltaic cleaning mechanism 1 and is connected to the control center. The sensor 2 is installed on the photovoltaic cleaning mechanism 1. The sensor 2 extends outward from the width direction of the photovoltaic cleaning mechanism 1. The sensor 2 is electrically connected to the controller. The sensor 2 is configured so that when it conflicts with the bridge mechanism 300, the controller controls the photovoltaic cleaning mechanism 1 to stop and / or return. In this way, the photovoltaic cleaning device 100 is prevented from being stuck between the bridge mechanism 300 and the first photovoltaic assembly 210, and the power of the photovoltaic cleaning device 100 is avoided. The shape of the sensor 2 extending outward is not limited. In this embodiment, the sensor 2 is rod-shaped. In other embodiments, the sensor 2 can be bent, arc-shaped or other shapes, or multiple brackets can be installed. The sensor 2 and the bridge mechanism 300 are in point contact, line contact or surface contact to improve the accuracy of detection. In this embodiment, the sensor 2 is a proximity switch.

[0043] The sensor 2 extends obliquely downward from the connection with the photovoltaic cleaning mechanism 1, and there is a second angle b between the sensor 2 and the photovoltaic cleaning mechanism 1. When the photovoltaic cleaning mechanism 1 moves to the connection between the first photovoltaic component 210 and the bridge mechanism 300, if the end of the sensor 2 conflicts with the bridge mechanism 300, the controller controls the photovoltaic cleaning mechanism 1 to stop and / or return to avoid the photovoltaic cleaning mechanism 1 from getting stuck at the connection. When the photovoltaic cleaning mechanism 1 moves to the connection between the first photovoltaic component 210 and the bridge mechanism 300, the end of the sensor 2 does not conflict with the bridge mechanism 300, and the photovoltaic cleaning mechanism 1 can pass through the bridge mechanism 300 smoothly. Preferably, the length of the sensor 2 is 180 mm, and the installation angle between the sensor 2 and the photovoltaic cleaning mechanism 1 is 39°.

[0044] Please refer to Figures 5 and 6 , the angle between the end of the sensor 2 and the plane where the bridge mechanism 300 in the traveling direction of the photovoltaic cleaning device is located is the critical first angle c. That is, if the angle range of the first angle a between the bridge mechanism 300 and the first photovoltaic assembly 210 is within the angle range of the critical first angle c, the photovoltaic cleaning mechanism 1 can smoothly pass through the bridge mechanism 300.

[0045] Please refer to Figure 1 to Figure 2 as well as Figure 4, the sensor 2 includes a first sensor 21 and a second sensor 22, the first sensor 21 and the second sensor 22 are respectively arranged on both sides of the width direction of the photovoltaic cleaning mechanism 1, and the first sensor 21 and the second sensor 22 are symmetrically arranged relative to the central cross section of the photovoltaic cleaning mechanism 1. Specifically, the photovoltaic assembly 200 also includes a third photovoltaic assembly, the third photovoltaic assembly is arranged on the side of the first photovoltaic assembly 210 away from the second photovoltaic assembly 220, the third photovoltaic assembly and the first photovoltaic assembly 210 are also connected through the bridge mechanism 300, and the bridge mechanism 300 and the first photovoltaic assembly 210 have a first angle a. By arranging the first sensor 21 and the second sensor 22 on both sides of the photovoltaic cleaning mechanism 1, the photovoltaic cleaning mechanism 1 detects whether it can pass through the bridge mechanism 300 when it moves away from the docking frame. Similarly, when the photovoltaic cleaning mechanism 1 approaches the bridge mechanism 300 connected to the third photovoltaic assembly, the second sensor 22 detects whether it can pass through the bridge mechanism 300. In this way, the photovoltaic cleaning device 100 can control the photovoltaic cleaning mechanism 1 when it moves back and forth on the photovoltaic module, avoiding it from getting stuck on the bridge mechanism 300, thereby improving the cleaning efficiency.

[0046] In one embodiment, the sensor 2 includes a first sensor 21, a second sensor 22, a third sensor and a fourth sensor. The first sensor 21 and the second sensor 22 are respectively arranged on both sides of the width direction of the photovoltaic cleaning mechanism 1. The bridge mechanism 300 includes an upper bridge 310 and a lower bridge 320. The first sensor 21 and the second sensor 22 are used to detect the upper bridge 310. The third sensor and the fourth sensor are respectively arranged on both sides of the width direction of the photovoltaic cleaning mechanism 1. The third sensor and the fourth sensor are symmetrically arranged along the central cross section of the photovoltaic cleaning mechanism 1. The third sensor and the fourth sensor are used to detect the lower bridge 320. When any one of the first sensor 21, the second sensor 22, the third sensor and the fourth sensor approaches the bridge mechanism 300 and conflicts with the bridge mechanism 300, the sensor sends a signal to the controller, and the controller controls the photovoltaic cleaning mechanism 1 to stop and / or return to prevent the photovoltaic cleaning mechanism 1 from being stuck on the bridge mechanism 300. When the photovoltaic cleaning mechanism 1 moves close to the bridge structure, if the first sensor 21, the second sensor 22, the third sensor and the fourth sensor do not interfere with the bridge structure, it means that the photovoltaic cleaning mechanism 1 can pass smoothly.

[0047] Please refer to Figure 7In one embodiment, the photovoltaic cleaning mechanism 1 includes a frame 11, an active drive box 12 and a driven drive box 13 respectively arranged on both sides of the frame 11 along the length direction thereof, an upper walking wheel 14 connected to the active drive box 12, a lower walking wheel 15 connected to the driven drive box 13, and a brush 16 arranged at the bottom of the frame 11, a first sensor 21 and a second sensor 22 are arranged on both sides of the active drive box 12 along the width direction thereof, or the first sensor 21 and the second sensor 22 are arranged on both sides of the driven drive box 13 along the width direction thereof.

[0048] In one embodiment, the active drive box 12 and the driven drive box 13 are arranged on the outside of the frame 11, the sensor 2 is installed on the active drive box 12, or the sensor 2 is installed on the driven drive box 13, or the sensor 2 is installed on the frame 11. In one embodiment, the active drive box 12 and the driven drive box 13 are arranged at the bottom of both ends of the frame 11, the sensor 2 is installed on the active drive box 12, or the sensor 2 is installed on the driven drive box 13, or the sensor 2 is installed on the frame 11. The active drive box 12 and the driven drive box 13 are respectively equipped with a walking wheel set, the active drive box 12 is connected to the upper walking wheel 14, the driven drive box 13 is connected to the lower walking wheel 15, and the sensor 2 is arranged in the walking direction of the upper walking wheel 14 or the lower walking wheel 15 for easy installation.

[0049] In summary, the photovoltaic cleaning device 100 of the present patent application is provided with a sensor 2 on the photovoltaic cleaning mechanism 1. When there is a misalignment or rotation angle difference between the two photovoltaic brackets on which the first photovoltaic component 210 and the second photovoltaic component 220 are installed, the bridge mechanism 300 connecting the two photovoltaic brackets is lifted or dropped relative to the photovoltaic components. When the lifting angle (i.e., the first angle a) of the bridge mechanism 300 relative to the photovoltaic components is too large or the falling angle exceeds the set angle value, the photovoltaic cleaning mechanism 1 moves to the bridge mechanism 300 between the first photovoltaic component 210 and the second photovoltaic component 220, and the end of the sensor 2 collides with the bridge mechanism 300. Then, the controller controls the photovoltaic cleaning mechanism 1 to stop and / or return to avoid the photovoltaic cleaning mechanism 1 being stuck at the connection between the photovoltaic bracket and the bridge mechanism 300, and determines that the bridge mechanism 300 or the tracker has a fault.
