[0037] like Figures 1 to 3 As shown, this embodiment provides a crawler-type mobile mechanism, wherein the crawler-type mobile mechanism is connected to the base 100 of the operation and maintenance equipment of the photovoltaic assembly 200. The crawler-type mobile mechanism includes a driving wheel assembly 1, a transmission belt 2, a driven wheel 3, a connecting member 4, and a spring shock absorber 5. The driving wheel assembly 1 includes a driving wheel 13, wherein the driving wheel 13 is connected to the driven wheel 3 via the transmission belt 2. This can increase the contact area between the crawler-type mobile mechanism and the photovoltaic assembly 200, and improve the stability of the operation and maintenance equipment when crossing obstacles in different photovoltaic assemblies 200. The connecting member 4 is placed beside the driving wheel assembly 1 and the driven wheel 3, so that the crawler-type mobile mechanism is rationally arranged. The connecting member 4 is fixedly connected to the driving wheel assembly 1, and one end of the spring shock absorber 5 is rotatably connected to the base 100, and the other end is rotatably connected to the connecting member 4. In this way, when the operation and maintenance equipment crosses obstacles in different photovoltaic assemblies 200, the spring shock absorber 5 can buffer the vibration of the operation and maintenance equipment, thereby further improving the overall stability of the operation and maintenance equipment during the movement of different photovoltaic assemblies 200.

[0038] The crawler-type mobile mechanism provided in this embodiment can increase the contact area between the crawler-type mobile mechanism and the photovoltaic module 200 by using a transmission belt 2 to connect the driving wheel 13 and the driven wheel 3 to drive the operation and maintenance equipment to move, so that the stability of the operation and maintenance equipment in moving across obstacles of different photovoltaic modules 200 is guaranteed, and the vibration amplitude of the operation and maintenance equipment is reduced. At the same time, a connector 4 fixedly connected to the driving wheel assembly 1 is provided, and a spring shock absorber 5 is connected between the connector 4 and the base 100. When the operation and maintenance equipment moves between photovoltaic modules 200 of different heights, the spring shock absorber 5 can buffer the vibration of the operation and maintenance equipment, thereby further reducing the vibration amplitude of the operation and maintenance equipment when crossing obstacles between different photovoltaic modules 200, so that the operation and maintenance equipment can better adapt to the height obstacles formed between different photovoltaic modules 200, better maintain the photovoltaic modules 200, and adapt to the photovoltaic bracket scene.

[0039] Exemplarily, the driving wheel assembly 1 also includes a driving member 11 and a motor mounting seat 12. The driving member 11 includes a main body and an output end. The motor mounting seat 12 is fixedly connected to the main body. The output end is connected to the driving wheel 13 after passing through the motor mounting seat 12. The connecting member 4 is connected to the motor mounting seat 12, thereby realizing the connection between the connecting member 4 and the driving wheel assembly 1. Preferably, when the operation and maintenance equipment moves at the edge of the photovoltaic module 200, the driving member 11 is placed on the side of the driving wheel 13 away from the photovoltaic module 200. Since a frame is provided at the edge of the photovoltaic module 200, this can avoid friction between the bottom surface of the driving member 11 and the frame during the movement of the operation and maintenance equipment, thereby improving the service life of the frame and further improving the service life of the photovoltaic module 200.

[0040] Exemplarily, the connecting member 4 includes a connecting plate 41 and a fixed base 42, one end of the connecting plate 41 is connected to the motor mounting seat 12, and the other end is connected to the fixed base 42, and a mounting hole matching the diameter of the motor mounting seat 12 is provided on the connecting plate 41 so that the output end of the driving member 11 can extend. Specifically, the motor mounting seat 12 is a cylinder with openings at both ends, and an annular assembly portion is provided at both ends of the cylinder, one of the annular assembly portions is used to connect the motor mounting seat 12 to the main body, and the other annular assembly portion is used to connect the connecting plate 41 to the motor mounting seat 12, so as to facilitate the assembly of the connecting plate 41. Specifically, the motor mounting seat 12 is fixedly connected to the main body by bolts, and the connecting plate 41 is fixedly connected to the motor mounting seat 12 by bolts. Among them, the direction of the fixed base 42 is away from the driven wheel 3, so as to avoid interference between the fixed base 42 and the layout of the driven wheel 3, affecting the stability of the movement of the crawler mobile mechanism, and further improving the rationality of the design of the crawler mobile mechanism. The spring damper 5 is connected to the end of the fixed base 42 facing away from the connecting plate 41 to prevent interference between the spring damper 5 and the connecting plate 41, further ensuring the function of the spring damper 5 and the overall stability of the operation and maintenance equipment when crossing obstacles between different photovoltaic modules 200. The fixed base 42 has the same structure as the motor mounting base 12. The fixed base 42 includes a cylindrical body and annular mounting portions provided at each end of the cylindrical body. One of the annular mounting portions is fixedly connected to the connecting plate 41 by bolts, and the other annular mounting portion is rotatably connected to the spring damper 5.

[0041] Preferably, the crawler-type mobile mechanism further includes a fixing member 6, wherein the fixing member 6 is connected between the connecting plate 41 and the base 100 to achieve a fixed connection between the driving member 11 and the base 100. Preferably, one end of the spring shock absorber 5 is rotatably connected to the fixing member 6, and the other end is rotatably connected to the fixed base 42. Compared with directly connecting the spring shock absorber 5 to the base 100, the provision of the fixing member 6 provides workers with a larger operating space, more conveniently assembling the spring shock absorber 5, and reduces the assembly difficulty for workers. The fixing member 6 includes a connecting column 61, a connecting riser 62, and a connecting plate 63. The connecting column 61 is vertically connected to the connecting plate 41, facing away from the photovoltaic module 200. The connecting riser 62 is fixedly mounted on the connecting column 61, and the connecting plate 63 is fixedly connected to the connecting riser 62. Specifically, the spring shock absorber 5 is rotatably connected to the connecting plate 63. By adjusting the length of the connecting riser 62, the inclination of the spring shock absorber 5 can be adjusted, and the degree of cushioning of the spring shock absorber 5 on the operation and maintenance equipment can be adjusted.

[0042] For example, Figure 3 and Figure 4 As shown in , the spring shock absorber 5 includes a connecting rod 51, a sleeve 52, and an elastic member 53, which is movably connected to the sleeve 52. A first annular portion 511 is provided on the outer periphery of the connecting rod 51, wherein the diameter of the first annular portion 511 is larger than the diameter of the sleeve 52 to prevent the connecting rod 51 from completely entering the sleeve 52. A second annular portion 521 is provided on the outer periphery of the sleeve 52, and the elastic member 53 abuts between the first annular portion 511 and the second annular portion 521. In this way, when the operation and maintenance equipment moves between different photovoltaic modules 200, that is, when crossing obstacles, the connecting rod 51 and the sleeve 52 will produce relative movement, and the elastic member 53 will deform, thereby achieving a buffering effect on the vibration of the operation and maintenance equipment. In this embodiment, the elastic member 53 is a spring, which is sleeved on the outer periphery of the connecting rod 51 and the sleeve 52, and abuts between the first annular portion 511 and the second annular portion 521. In this way, when the spring is deformed, the connecting rod 51 and the sleeve 52 can guide the spring. In this way, when the operation and maintenance equipment moves between different photovoltaic modules 200, the spring shock absorber 5 can more stably buffer the operation and maintenance equipment, further improving the stability of the operation and maintenance equipment.

[0043] Furthermore, a strip hole 512 is provided on the circumference of the connecting rod 51, and two relative positioning holes are provided on the circumference of the sleeve 52, and the positioning holes are opposite to the strip holes 512. The spring shock absorber 5 also includes a first pin 54, wherein the first pin 54 passes through the positioning hole and the strip hole 512, and the first pin 54 is threadedly connected to one of the positioning holes. In this way, when the operation and maintenance equipment vibrates, it can play a guiding role in the movement of the connecting rod 51 and the sleeve 52, further improving the stability of the spring shock absorber 5 when the operation and maintenance equipment vibrates, thereby further improving the stability of the operation and maintenance equipment during movement. Specifically, one of the positioning holes is provided with an internal thread, and one end of the first pin 54 is provided with an external thread. During assembly, the end of the first pin 54 with the external thread passes through the positioning hole without the internal thread and the strip hole 512 in sequence, and is threadedly connected to the positioning hole with the internal thread. Alternatively, both positioning holes may be provided with internal threads, and both ends of the first pin 54 may be provided with external threads, so that the first pin 54 is threadedly connected to both positioning holes, further ensuring the stability of the overall structure of the spring damper 5.

[0044] Furthermore, the spring damper 5 also includes a first connecting member 55 and a second connecting member 56, wherein one end of the first connecting member 55 is connected to the end of the connecting rod 51 having the first annular portion 511, and the other end of the first connecting member 55 is rotatably connected to the connecting member 4 via a second pin 7, specifically, the fixed base 42. One end of the second connecting member 56 is connected to the end of the sleeve 52 having the second annular portion 521, and the other end of the second connecting member 56 is rotatably connected to the base 100 via a third pin 8. Specifically, the first connecting member 55 is integrally formed with the connecting rod 51, and a circular ring is provided at the end of the first connecting member 55 facing away from the connecting rod 51. The fixed base 42 is provided with an assembly hole, and the second pin 7 is threadedly connected to the assembly hole in the fixed base 42. The circular ring of the first connecting member 55 is sleeved on the second pin 7 to achieve rotatable connection between one end of the spring damper 5 and the connecting member 4. Preferably, a rubber sleeve is sleeved on the second pin 7 to prevent the spring damper 5 from falling off the second pin 7. Similarly, the second connecting member 56 is integrally formed with the sleeve 52. A circular ring is provided at the end of the second connecting member 56 facing away from the sleeve 52. A mounting hole is provided on the base 100. The third pin 8 is threadedly connected to the mounting hole on the base 100. The circular ring of the second connecting member 56 is sleeved on the third pin 8 to achieve a rotatable connection between the other end of the spring damper 5 and the base 100. Preferably, a rubber sleeve is provided on the third pin 8 to prevent the spring damper 5 from falling off the third pin 8.

[0045] In this embodiment, the crawler mobile mechanism also includes a synchronous wheel assembly 9, which is fixedly arranged on the connecting member 4 and placed between the driving wheel assembly 1 and the driven wheel 3, wherein the synchronous wheel assembly 9 includes a connecting shaft, a bearing and a synchronous wheel, wherein the connecting shaft is connected to the connecting member 4, and the connecting shaft is placed under the transmission member, the inner ring of the bearing is sleeved with the connecting shaft, the synchronous wheel is sleeved on the outer ring of the bearing, and the circumferential surface of the synchronous wheel is in contact with the transmission belt 2. In this way, when the driving wheel assembly 1 drives the driven wheel 3 to rotate through the transmission belt 2 to realize the movement of the crawler mobile mechanism, the synchronous wheel rotates synchronously with the movement of the transmission belt 2. The setting of the synchronous wheel can make the movement of the transmission belt 2 more stable. When the transmission belt 2 rotates with the driving wheel 13 and the driven wheel 3, the overall shape is smoother, reducing the risk of the transmission belt 2 falling off the driving wheel 13 and the driven wheel 3, and improving the stability of the movement of the crawler mobile mechanism.
