[0038] The shaft support of the single-motor photovoltaic cleaning device 200 provided in the application has a simple structure, can realize stable support of the transmission shaft, and guarantees the reliability of the transmission force performance of the transmission shaft 31.

[0039] Referring to FIG. 1, Figures 1 to 9 In the embodiment, the driving assembly 10 is arranged at the upper opening 201 of the single-motor photovoltaic cleaning device 200, and the driven assembly 20 is arranged at the lower opening 202 of the single-motor photovoltaic cleaning device 200. That is, the photovoltaic array 100 is arranged in an inclined manner, the driving assembly 10 is located at one side of the upper end of the photovoltaic array 100, and the driven assembly 20 is arranged at one side of the lower end of the photovoltaic array 100. The driving assembly 10 and the driven assembly 20 each comprise a mounting support, a walking wheel, and a track roller.

[0040] Referring to FIG. 1, Figure 3 Specifically, the driving assembly 10 comprises a driving mounting support 15, a motor 11, a driving walking wheel 13, and a driving track roller 14. The motor 11, the driving walking wheel 13, and the driving track roller 14 are mounted on the driving mounting support 15. The motor 11 has a motor shaft 12, the driving walking wheel 13 is a toothed wheel having a cylindrical tooth, and the driving walking wheel 13 is connected to the motor shaft 12 through a key groove to be driven to rotate by the motor shaft 12. The driving walking wheel 13 walks on the track 5 having a tooth hole, and the driving track roller 14 is a pair of oppositely arranged rollers, which are clamped on both sides of the track 5.

[0041] Referring to FIG. 1, Figure 4As shown, the driven assembly 20 does not include the motor 11, and other components are substantially similar to the driving assembly 10. Specifically, the driven assembly 20 includes a driven mounting support 21, a driven shaft 22, a driven walking wheel 23 and a driven track roller 24. The driven walking wheel 23 and the driven track roller 24 are mounted on the driven mounting support 21. The driven walking wheel 23 is a toothed wheel with cylindrical teeth, and the driven walking wheel 23 is connected to the driven shaft 22 by a key groove to be driven to rotate by the driven shaft 22. The driven walking wheel 23 walks on the track 5 with a toothed hole, and the driven track roller 24 is a pair of oppositely arranged rollers clamped on both sides of the track 5. It can be understood that the driving assembly 10 and the driven assembly 20 can also include bearings and the like to ensure the smooth rotation of the motor shaft 12 and the driven shaft 22.

[0042] Referring to Figure 5 As shown, the transmission assembly 30 includes a transmission shaft 31 and a connecting sleeve 32, and the connecting sleeve 32 is sleeved on the motor shaft 12 and one end of the transmission shaft 31 to connect the motor shaft 12 and one end of the transmission shaft 31. In this embodiment, the transmission shaft 31 includes multiple segments, and the connecting sleeve 32 is also sleeved between adjacent two segments of the transmission shaft 31. The motor shaft 12, the transmission shaft 31 and the connecting sleeve 32 are provided with radially extending connecting holes, and the motor shaft 12 and the connecting sleeve 32, and the transmission shaft 31 and the connecting sleeve 32 are respectively connected and fixed by inserting pins into the connecting holes. The diameter of the pin matches the diameter of the connecting hole, so that when the pin is inserted into the connecting hole, the two parts to be connected are fixed in the circumferential direction and the axial direction.

[0043] Referring again to Figure 4 As shown, the transmission assembly 30 includes a sliding sleeve 33, and the sliding sleeve 33 is sleeved on the driven shaft 22 and one end of the transmission shaft 31, and the sliding sleeve 33 is provided with a sliding groove 331 extending in the axial direction. The sliding sleeve 33 and the transmission shaft 31 are connected and fixed by a pin, and the sliding sleeve 33 and the driven shaft 22 are connected and fixed by a pin in the sliding groove 331 to realize the relative movement of the driven shaft 22 and the sliding sleeve 33. In other embodiments, the sliding groove 331 can also be provided on the driven shaft 22. The width of the pin matches the width of the sliding groove 331, so that when the pin is inserted into the connecting hole, the driven shaft 22 and the sliding sleeve 33 are relatively fixed in the circumferential direction, and in the axial direction, that is, the length direction of the sliding groove 331, the driven shaft 22 and the sliding sleeve 33 can relatively slide.

[0044] In the circumferential direction of the transmission shaft 31, the transmission shaft 31 is fixed relative to the motor shaft 12 and the driven shaft 22, so that the motor shaft 12, the transmission shaft 31 and the driven shaft 22 rotate synchronously in the circumferential direction; in the axial direction of the transmission shaft 31, the transmission shaft 31 is fixed relative to the motor shaft 12, while the driven shaft 22 is movable relative to the transmission shaft 31 for floating adjustment in the axial direction. That is, the single-motor photovoltaic cleaning device 200 provided by the present application is characterized in that, in the circumferential direction of the transmission shaft 31, the transmission shaft 31 is fixed relative to the motor shaft 12 and the driven shaft 22, so that the motor shaft 12, the transmission shaft 31 and the driven shaft 22 rotate synchronously in the circumferential direction, and in the axial direction of the transmission shaft 31, the transmission shaft 31 is fixed relative to the motor shaft 12, while the driven shaft 22 is movable relative to the transmission shaft 31 for floating adjustment in the axial direction, so that the power transmission is stable and reliable, and the distance between the driving assembly 10 and the driven assembly 20 can be adjusted to avoid being stuck.

[0045] As shown in Figure 1 and Figures 6 to 8 The walking beam 4 is connected to the driving mounting support 15 and the driven mounting support 21 at two ends, respectively. The lifting connector 41 includes a transverse plate 411 and a longitudinal plate 412 extending downward from the transverse plate 411, and the transverse plate 411 and the longitudinal plate 412 are connected to form a structure in the shape of a “7” in cross section. The transverse plate 411 is fixedly connected to the walking beam 4, and the longitudinal plate 412 is provided with a hole through which the transmission shaft 31 passes. The lifting connector 41 can be provided in multiple numbers, and the multiple lifting connectors 41 are uniformly and spacedly distributed in the axial direction of the transmission shaft 31 to lift the transmission shaft 31 and prevent the transmission shaft 31 from being bent downward under the action of its own gravity when it is relatively long. Further, a clamp bearing 43 is arranged between the transmission shaft 31 and the hole through which the transmission shaft 31 passes, so that the transmission shaft 31 can be lifted and supported upward, and the rotation of the transmission shaft 31 is facilitated.

[0046] As shown in Figure 9As shown, the shaft support further comprises a support wheel assembly 42, which comprises a support wheel bracket 421 connecting the walking beam 4 and the transmission shaft 31, and a support wheel 422 rotatably connected to the support wheel bracket 421. In this embodiment, the support wheel bracket 421 comprises a transversely extending base plate 4211, and an axle connecting plate 4212 and a support wheel mounting plate 4213 longitudinally extending from the base plate 4211, the axle connecting plate 4212 being provided with a hole for the transmission shaft 31 to pass through. The support wheel 422 is two, symmetrically arranged on both sides of the transmission shaft 31, so that the support is more stable. The transmission shaft 31 and the hole on the axle connecting plate 4212 are provided with a clamp bearing 43, which can support the transmission shaft 31 upwardly while facilitating the rotation of the transmission shaft 31.

[0047] In this embodiment, the shaft support comprises the hoisting and pulling connecting piece 41 and the support wheel assembly 42, which are reasonably distributed in the axial direction of the transmission shaft 31 to stably support the transmission shaft 31. In this embodiment, the hoisting and pulling connecting piece 41 is multiple, and the number of the hoisting and pulling connecting piece 41 is more than that of the support wheel assembly 42. The hoisting and pulling connecting piece 41 is simple in structure and can be provided more than the support wheel assembly 42. The support wheel 422 of the support wheel assembly 42 needs to be supported on the photovoltaic array 100, which, while hoisting and pulling the transmission shaft 31 to prevent the transmission shaft 31 from bending downwardly under its own gravity when it is long, increases a walking path, so that the walking of the single-motor photovoltaic cleaning device 200 is more stable. However, when the support wheel assembly 42 moves across the photovoltaic array 100, a bridge beam for the support wheel assembly 42 to walk is also needed to be arranged between adjacent photovoltaic arrays 100, so its cost is relatively high. In this embodiment, a few groups of support wheel assemblies 42 are arranged, which are replaced by the hoisting and pulling connecting piece 41, so that the arrangement of the bridge beam can be reduced and the cost can be reduced. In this embodiment, the support wheel assembly 42 is multiple, and the distance between adjacent two hoisting and pulling connecting pieces 41 is less than the distance between adjacent two support wheel assemblies 42. That is, the hoisting and pulling connecting piece 41 is arranged more densely, and the support wheel assembly 42 is arranged more sparsely, so that the product cost can be reduced while the stable support is ensured. For example, the hoisting and pulling connecting piece 41 is arranged every 2 meters; and the support wheel assembly 42 is arranged every 4 meters.

[0048] Please refer to Figures 10 to 13As shown, it is a diagram of the second embodiment of the single motor photovoltaic cleaning device 200. The main difference between this embodiment and the first embodiment is that the first embodiment has two tracks 5 and one driving assembly 10 and one driven assembly 20, while this embodiment has three tracks 5 and one driving assembly 10 and two driven assemblies 20. Of course, further, the number of tracks 5 and the number of driven assemblies 20 can be further increased. In other words, the driven assemblies 20 are multiple, and at least one driven assembly 20 is arranged between the upper opening 201 and the lower opening 202 of the single motor photovoltaic cleaning device 200. By adding one track 5 and one driven assembly 20, the single motor photovoltaic cleaning device 200 can further increase the length by walking between the upper opening 201 and the lower opening 202.

[0049] As shown in FIG. 1, the single motor photovoltaic cleaning device 200 includes a driving assembly 10, a track 5, and a driven assembly 20.

In this embodiment, the driving assemblies 20 are arranged at the upper opening 201 and the lower opening 202, and the driving force output by the driving assembly 10 is transmitted to both sides.

[0051] Specifically, the driven assembly 20 is arranged to be at least two, and is arranged at the upper opening 201 and the lower opening 202 of the single motor photovoltaic cleaning device 200, and the driving assembly 10 is arranged between the upper opening 201 and the lower opening 202 of the single motor photovoltaic cleaning device 200.

The motor support wheel 112 is not directly driven by the motor 11, the motor 11 drives the driven assemblies 20 at both ends to walk, and the motor support wheel 112 passively rolls with the walking beam 4, which mainly plays a supporting role.

[0053] The connection between the driving assembly 10 and the driven assembly 20 adopts a transmission assembly 30, which can be arranged as described in any of the above embodiments. That is, the transmission assembly 30 comprises a transmission shaft 31, a connecting sleeve 32, and a sliding sleeve 33.

The driven shaft 22 and the other end of the transmission shaft 31 are connected by the sliding sleeve 33 and are fixed relative to each other in the circumferential direction but are allowed to slide relative to each other in the axial direction.

[0054] The driving assembly 10 provided in the embodiment can be arranged at any position in the axial direction of the transmission assembly 30 and only needs to be connected to the driven assembly 20 at both ends. The photovoltaic array 100 also does not need to be arranged differently for the driving assembly 10 and can be normally arranged without the need to set a clearance. The driving assembly 10 is preferably arranged between two adjacent photovoltaic panels, so that the motor support wheel 112 can ride and walk on the frames of the two adjacent photovoltaic panels. In the embodiment, the driven assembly 20 comprises a toothed walking wheel walking on the track 5 with a tooth hole and a track roller clamped on both sides of the track 5.
