The push rod assembly 4 includes at least one push rod, and the controller 3 can control the extension and retraction of the push rod, so that the cleaning robot 1 can be suspended below the horizontal frame 23 with adjustable height and angle. When the cleaning robot 1 moves with the frame 2 to the seam between two photovoltaic modules 200, the controller 3 controls the frame 2 to remain stationary, and the photovoltaic cleaning device 100 stops moving forward. At this time, the photovoltaic cleaning device 100, through the controller 3, controls at least one push rod to lift the cleaning robot 1. When the lifting height meets the height of the next photovoltaic module 200, the controller 3 controls at least one push rod to stop lifting the cleaning robot 1, and the controller 3 controls the frame 2 to resume its moving state, driving the entire photovoltaic cleaning device 100 forward to the location of the next photovoltaic module 200. Then, at least one push rod lowers the cleaning robot 1. Therefore, the photovoltaic cleaning device 100 of this utility model can easily, quickly, and effectively transport the cleaning robot 1 between two adjacent photovoltaic modules 200 through a single lift, move, and lower operation.

[0029] Please refer to Figures 1 to 4 As shown, the push rod assembly 4 includes a first push rod 41 and a second push rod 42, which are respectively fixed to the horizontal frame 23. The first push rod 41 and the second push rod 42 are respectively connected to opposite ends of the cleaning robot 1. The controller 3 can control the extension and retraction of the first push rod 41 and the second push rod 42, so that the cleaning robot 1 can be suspended below the horizontal frame 23 with adjustable height and angle. Therefore, as described above, at least one push rod in this specific embodiment of the present invention consists of two push rods (the first push rod 41 on the left and the second push rod 42 on the right), which suspend opposite ends of the cleaning robot 1 below the horizontal frame 23. Since the controller 3 can control the extension and retraction of the first push rod 41 and the second push rod 42, in this specific embodiment of the present invention, the two push rods (the first push rod 41 on the left and the second push rod 42 on the right) can help achieve the left-right balance of the cleaning robot 1, that is, the cleaning robot 1 can be lifted and lowered in a balanced manner, and the pick-up and placement are stable.

The push rod assembly 4 also includes a third push rod 43 that is controlled to extend and retract by the controller 3. One end of the third push rod 43 is fixedly connected to the first horizontal frame 231 and the other end is fixedly connected to the sliding table assembly 5. The second horizontal frame 232 is movably connected to the lower part of the first horizontal frame 231 through the third push rod 43 and the sliding table assembly 5. That is to say, in a specific embodiment of this utility model, the cleaning robot 1 can also be moved left and right by pushing the sliding table assembly 5 with the third push rod 43, so as to realize the movement from the previous photovoltaic module 200 (e.g., Figures 1 to 3 From the first photovoltaic module 201 to the next photovoltaic module 200 (e.g. Figures 1 to 3 The width position of the second photovoltaic module 202 in the cleaning robot 1 is determined, and the pose of the cleaning robot 1 is adjusted in conjunction with the ultrasonic sensor on the cleaning robot 1.

[0031] Please refer to Figures 1 to 4 As shown, it should be noted that in the preferred embodiment, the first push rod 41 and the second push rod 42 extend and retract in the vertical direction, while the third push rod 43 extends and retracts in the horizontal direction. This arrangement makes the product structure compact and facilitates the forward and backward movement and left and right adjustment of the cleaning robot 1.

[0032] Please refer to Figure 3 and Figure 4 As shown, each of the first push rod 41, the second push rod 42, and the third push rod 43 includes a main body 401 and a movable part 402. The movable part 402 is connected to the main body 401 and can extend and retract relative to the main body 401.

The slide assembly 5 includes both a fixed base portion 51 and a protrusion 52 that can slide relative to the base portion 51. Therefore, this invention allows for adjustment of the position of the cleaning robot 1 in the left-right direction, i.e., the width direction.

[0034] Please refer to Figures 4 to 8As shown, the protrusion 52 includes at least one base portion 521 and a head 522 located above the base portion 521. The base portion 51 has a vertically penetrating slot 510, through which the protrusion 52 passes. The base portion 521 and part of the head 522 pass through the slot 510 and are located on the upper and lower sides of the base portion 51. The base portion 521 is used for the guide rod 53 to pass through, and the head 522 is used for connection with the third push rod 43. Please refer to... Figure 5 , Figure 6 and Figure 8 The head 522 is provided with a positioning hole 5220 for positioning the end of the third push rod 43. The fixed base part 51 is used to fix with the first horizontal frame 231, and the slidable protrusion 52 is used to move with the second horizontal frame 232. Therefore, the sliding of the protrusion 52 relative to the base part 51 can drive the second horizontal frame 232 to move left and right relative to the first horizontal frame 231. The cleaning robot 1 is specifically suspended below the second horizontal frame 232, and the left and right movement of the cleaning robot 1 is realized by pushing the slide assembly 5 through the third push rod 43 to achieve the width position from the previous photovoltaic module 200 to the next photovoltaic module 200. The position and posture of the cleaning robot 1 are adjusted in conjunction with the ultrasonic sensor on the cleaning robot 1.

[0035] Please refer to Figure 5 and Figure 6 As shown, the guide rod 53 includes a first guide rod 531 and a second guide rod 532. The first guide rod 531 and the second guide rod 532 are fixed parallel to each other below the base portion 51. At least one base portion 521 is used for the first guide rod 531 and the second guide rod 532 to pass through. The two guide rods 53 are arranged one after the other, providing a sliding track with balance and stability.

[0036] Please refer to Figure 1 and Figure 2 The present invention also includes a cover 10 located between the first horizontal frame 231 and the second horizontal frame 232. The cover shields the slide assembly 5, the third push rod 43, the controller 3 and other electronic components, and has a dustproof function.

[0037] Please refer to Figure 1 , Figure 2 and Figure 9 , Figure 10As shown, this utility model also includes a connecting rope 6, and a connecting frame 7 is provided at each of the opposite ends of the cleaning robot 1. The second push rod 42 and the first push rod 41 are respectively connected to the corresponding connecting frame 7 via the connecting rope 6. The connecting rope 6 and the connecting frame 7 serve to connect the push rods 31 and 32 to the cleaning robot 1.

[0038] Please refer to Figure 3 As shown, this utility model also includes a monitoring element 8, which is mounted on the horizontal frame 23 and electrically connected to the controller 3. The monitoring element 8 faces the cleaning robot 1. The monitoring element 8 can be a camera (e.g., a 3D depth camera). The function of the 3D depth camera is to detect whether the movement of the cleaning robot 1 has reached the joint position between the front and rear rows of photovoltaic modules 200.

[0039] Please refer to Figures 1 to 3 As shown, both the first vertical frame 21 and the second vertical frame 22 are equipped with tracked moving units 9 at their bottoms. The function of the tracked moving units 9 is to provide mobility for the frame 2.

[0040] In summary, in this specific embodiment, the controller 3 controls the extension and retraction of the first push rod 41 and the second push rod 42, allowing the cleaning robot 1 to be suspended at an adjustable height below the horizontal frame 23. Therefore, when the cleaning robot 1 moves to the seam between the two photovoltaic modules 200, the photovoltaic cleaning device 100 stops moving forward. The photovoltaic cleaning device 100, through the controller 3, controls the first push rod 41 and the second push rod 42 to lift the cleaning robot 1. When the lifting height meets the height of the next photovoltaic module 200, the controller 3 controls the first push rod 41 and the second push rod 42 to stop lifting. The movable frame 2 then moves the entire photovoltaic cleaning device 100 forward to the location of the next photovoltaic module 200, after which the first push rod 41 and the second push rod 42 lower the cleaning robot 1. In other embodiments, the present invention uses a push rod positioned at the center of the cleaning robot 1 to lift and lower the cleaning robot 1. In summary, this utility model enables the cleaning robot 1 to move between two adjacent photovoltaic modules 200 easily, quickly, and effectively through a simple lifting, moving, and placing motion.
