In addition, if the operation time is too long, debris may accumulate in the gaps of the bridge, affecting the normal operation of the bridge, and the bridge may fail to return to its original position. This not only makes it impossible for the cleaning robot to pass through the bridge, but also may cause secondary damage to the bridge or damage the cleaning robot.

[0004] Therefore, a movable bridge detection device and a photovoltaic power generation array that can detect whether the movable bridge has returned to its original position to prevent the cleaning robot from falling and being damaged need to be designed. Utility Model Content

[0046] Please refer to Figures 1 to 7On the one hand, the embodiment of the utility model provides a movable bridge detection device 100, which is used to detect whether the movable bridge 300 of two adjacent photovoltaic power generation devices 200 on the photovoltaic array 1000 is faulty, so as to control the movement of the cleaning robot 400 and timely repair. The movable bridge detection device 100 includes: an electronic tag 1, a tag sensing device 2 and a control module 3. Among them, the electronic tag 1 is a radio frequency identification tag (RFID) tag or an RFID chip, which is a component of an automatic identification technology that uses radio waves for communication. Specifically, the technology is a prior art, so it is not expanded here. In this embodiment, the electronic tag 1 is configured at the connection area of ​​the rotating beam 310 and the side beam 320 of the movable bridge 300. That is, it is configured at the corner area of ​​the movable bridge 300 at the junction of the movable bridge 300 and the photovoltaic power generation device 200, which can be located at one end of the rotating beam 310 close to the side beam 320, or at one end of the side beam 320 close to the rotating beam 310. Specifically, the movable bridge 300 is a prior art, and reference may be made to the Chinese utility model patent with the authorization announcement number "CN217404770U", which discloses the specific structure of the movable bridge 300. Specifically, in this embodiment, the electronic tag 1 is used to store the product identification information corresponding to the movable bridge 300, that is, it contains the model, number, and location information of the stored movable bridge 300. The tag sensing device 2 is correspondingly configured on the side of the forward direction of the walking device 410 of the cleaning robot 400, and is used to read the product identification information in the electronic tag 1 by sensing the electronic tag 1. Optionally, the tag sensing device 2 is located on the side of the forward direction of the main walking wheel 411. Optionally, the cleaning robot 400 generally includes walking devices 410 located on both sides, and cleaning rollers 420 connected to the walking devices 410 on both sides; the walking device 410 generally includes and is installed near the bottom of the walking device 410, and is used to cooperate with the front of the photovoltaic panel frame or the front of the track of the photovoltaic power generation device 200. The main walking wheel 411, and the auxiliary walking wheel 412 used to cooperate with the side of the photovoltaic panel frame or the side of the track, and the anti-slip wheel 413 installed at the bottom of the walking device 410 extends from the front to the back of the photovoltaic panel. The control module 3 is configured on the cleaning robot 400 and is electrically connected to the tag sensing device 2, and is used to control the movement of the walking device 410 according to whether the movable bridge 300 is returned to its position.During operation, when the cleaning robot 400 moves forward, since the tag sensing device 2 is arranged on one side of the main walking wheel 411 in the forward direction, when it reaches the junction of the movable bridge 300 and the photovoltaic power generation device 200, the tag sensing device 2 located in the front first reaches the sensing area of ​​the electronic tag 1. If the information of the electronic tag 1 can be detected, it means that the movable bridge 300 is in a normal return state at this time, and the control module 3 controls the walking device 410 to continue to operate; if the information of the electronic tag 1 is not detected, it means that the movable bridge 300 is not in a normal return state at this time, and the cleaning robot 400 is controlled to stop moving or return to the parking position. In this way, the movable bridge detection device 100 can detect whether the movable bridge 300 is in the return state, which can prevent the cleaning robot 400 from falling and being damaged.

[0047] Optionally, see Figure 4 and Figure 6 In this embodiment, the electronic tag 1 is arranged on the bottom surface of the rotating beam 310 of the movable bridge 300 near one end of the side beam 320, and the tag sensing device 2 is arranged on the mounting frame 430 at the bottom of the walking device 410. Specifically, the electronic tag 1 is connected to the bottom surface of the rotating beam 310 through the mounting plate 5 and the fastener 6. In order to prevent the electronic tag 1 from being damaged due to the rigid collision with the mounting plate 5 when encountering abnormal impact, preferably, an elastic gasket is arranged between the electronic tag 1 and the mounting plate 5. Specifically, the elastic gasket is an EVA gasket 7. The mounting frame 430 includes: an anti-slip bracket 431 and an L-shaped mounting plate 432; the anti-slip bracket 431 is used for the anti-slip wheel 413 to be assembled, and the L-shaped mounting plate 432 is assembled on the anti-slip bracket 431 and is located outside the installation and configuration position of the anti-slip wheel 413. In this way, when the movable bridge 300 is in normal return, the tag sensing device 2 is just below the electronic tag 1, so the signal of the electronic tag 1 can be sensed.

[0048] In order to make the cleaning robot 400 judge the homing state of the movable bridge 300 in time when going back and forth, so as to find the fault of the movable bridge 300 in time, thereby avoiding the cleaning robot 400 from falling and being damaged. Preferably, in some embodiments, the connection areas of the four rotating beams 310 and the side beams 320 of the movable bridge 300 are all configured with electronic tags 1; the two outer sides of the walking device 410 on both sides of the cleaning robot 400 are configured with corresponding tag sensing devices 2. In this way, the fault of the movable bridge 300 that occurs after the cleaning robot 400 passes through the movable bridge 300 normally after leaving the warehouse can be judged when the cleaning robot 400 returns. Of course, in other embodiments, an electronic tag 1 can also be configured at the upper and lower ends of the connection area between the rotating beam 310 of the movable bridge 300 and one of the side beams 320, and the two outer sides of the walking device 410 on the corresponding side of the cleaning robot 400 are configured with corresponding tag sensing devices 2. In this way, the above-mentioned effect can also be achieved.

[0049] In order to facilitate the staff to promptly discover the damage of the movable bridge 300 and to facilitate timely repair, optionally, please refer to Figure 7 In this embodiment, the movable bridge detection device 100 further includes a signal sending module 4 configured on the cleaning robot 400, and the signal sending module 4 is electrically connected to the control module 3. In this way, when the tag sensing device 2 does not detect the electronic tag 1, the control module 3 can send information to the staff through the signal sending module 4.

[0050] Please refer to Figures 1 to 7 On the other hand, the utility model provides a photovoltaic power generation array, including at least two photovoltaic power generation devices 200, a movable bridge 300 connecting two adjacent photovoltaic power generation devices 200, a cleaning robot 400 that can be arranged on the photovoltaic panels on the photovoltaic power generation devices 200 and the movable bridge 300, and the movable bridge detection device 100 as described above. Since the photovoltaic power generation array has all the structures and connection relationships of the movable bridge detection device 100, it has all the advantages of the movable bridge detection device 100, which will not be described in detail here.

[0051] In order to prevent the walking device 410 of the cleaning robot 400 from being damaged due to accidental collision, optionally, please refer to Figure 8 and Fig. 9 In some embodiments, the movable bridge detection device 100 further includes an anti-collision obstacle avoidance device 500 electrically connected to the control module 3, and the anti-collision obstacle avoidance device 500 is arranged on the walking device 410 of the cleaning robot 400 and is located on the side opposite to the tag sensing device 2. Specifically, the anti-collision obstacle avoidance device 500 is mounted on the lower side of the walking device 410 housing, and includes: an anti-touch mounting plate 510 connected to the walking device 410 housing; a proximity short switch 520 mounted on the anti-touch mounting plate 510 and arranged in the same direction as the forward direction of the main walking wheel 411; and an elastic collision head assembly 530 arranged on the anti-touch mounting plate 510 at an angle downward. Specifically, the proximity short switch 520 is used to sense obstacles in front of the operation; the elastic collision head assembly 530 is used to buffer the collision from the lower side. Specifically, the elastic collision head assembly 530 includes a collision head shell 531 fixed on the anti-touch mounting plate 510, and a collision head 533 slidably configured in the collision head shell 531, and a compression spring 532 located between the collision head 533 and the collision head shell 531.
