Abstract
Description
Technical Field
[0001] This utility model belongs to the field of robotics technology, and specifically relates to a tracked walking mechanism and its photovoltaic panel cleaning vehicle. Background Technology
[0002] Photovoltaic panel cleaning robots are used to clean the photovoltaic panels in photovoltaic power plants. Over time, dust can easily accumulate on the surface of photovoltaic panels, affecting power generation efficiency.
[0003] Cleaning robots typically have a walking mechanism mounted on a chassis for movement, usually in the form of tracks. In the track assembly, the drive wheels are located at the rear, and during actual use, the drive wheels and tracks are connected via toothed engagement. For photovoltaic panel cleaning robots, to ensure the photovoltaic panels are not damaged, the tracks are typically required to maintain maximum contact with them. Therefore, the drive wheels are usually at the same height as the other driven wheels. However, this design means that when the robot encounters protruding areas at the photovoltaic panel connections, it cannot adaptively adjust the height of the driven wheels. This prevents the tracks from maintaining maximum contact with the panels in such situations, leading to partial track suspension and slippage, which affects the robot's stability. Utility Model Content
[0004] To address the aforementioned issues, this invention provides a tracked walking mechanism and its photovoltaic panel cleaning trolley, which solves the problem that existing tracked photovoltaic panel cleaning robots experience partial suspension of the track and slippage when encountering protruding areas at the connection points of photovoltaic panels during operation, thus affecting the walking stability of the cleaning robot.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A tracked walking mechanism and its photovoltaic panel cleaning vehicle include two driving wheels, multiple driven wheel sets, a buffer component, and a main frame; the two driving wheels are movably connected to both ends of the main frame and are driven to rotate by a drive component; the driven wheel sets are disposed between the two driving wheels, and their peripheries are connected by a track; one end of the buffer component is connected to the main frame, and the other end is connected to the driven wheel sets, and the height of the driven wheel sets is adjusted by floating through the buffer component.
[0007] Preferably, the main frame includes two limiting plates, which are arranged opposite to each other and connected by a reinforcing plate and multiple limiting rods. The buffer component is connected between the two limiting plates by the limiting rods. A handle is provided on one side of the main frame, and two connecting arms are provided on the side of the main frame with the handle, symmetrically arranged at both ends of the main frame.
[0008] Preferably, the buffer component includes a first connecting rod, a spring, and a second connecting rod.

One end of the second connecting rod is movably sleeved on the periphery of the limiting rod, and the other end is sleeved on the periphery of the central shaft of the driven wheel assembly.
[0009] Preferably, the middle part of the second connecting rod is provided with a relief groove corresponding to the spring, and one end of the spring passes through the relief groove and is limited by a pin.
[0010] Preferably, the handle has a U-shaped structure, with its ends extending through two limiting plates and connected to the limiting plates in sequence, and the middle part of the handle protruding from one of the limiting plates.

[0026] To resolve the above issues, please refer to [link / reference]. Figures 1 to 4This utility model provides a tracked walking mechanism and its photovoltaic panel cleaning vehicle, including two driving wheels 1, multiple driven wheel sets 2, a buffer component 3, and a main frame 4. The two driving wheels 1 are movably connected to both ends of the main frame 4 and are driven to rotate by a driving component. The driven wheel sets 2 are disposed between the two driving wheels 1, and their peripheries are connected by a track 5. One end of the buffer component 3 is connected to the main frame 4, and the other end is connected to the driven wheel sets 2. The driven wheel sets 2 are adjusted in height by floating through the buffer component 3. A handle 6 is provided on one side of the main frame 4, and two connecting arms 7 are provided on the side of the main frame 4 with the handle 6, symmetrically arranged at both ends of the main frame 4. The driving wheels 1 are movably connected to the main frame 4 by a driving component such as a motor, so that they rotate relative to the main frame 4 to cooperate with the driven wheel sets 2 and the track 5 to achieve walking.
[0027] In optional embodiments, such as Figure 2 and Figure 4 As shown, the main frame 4 includes two limiting plates 41, which are arranged opposite to each other and connected by a reinforcing plate 42 and multiple limiting rods 43. The buffer component 3 is connected between the two limiting plates 41 by the limiting rods 43. One of the limiting plates 41 is used to connect the tracked walking mechanism and the photovoltaic panel cleaning vehicle 9. The two limiting plates 41 are fixed to each other by the reinforcing plate 42 and the limiting rods 43, which can determine the relative position between the two limiting plates 41, making it less likely to shift or deform, and ensuring the robustness and stability of the tracked walking mechanism. The reinforcing plate 42 has a U-shaped structure, and its two ends are screwed between the two limiting plates 41. The limiting rods 43 are set between the driven wheel set 2 and the driving wheel 1 and between adjacent driven wheel sets 2.
[0028] In optional embodiments, such as Figure 3 As shown, the buffer component 3 includes a first connecting rod 31, a spring 32, and a second connecting rod 33. The ends of the first connecting rod 31 are respectively connected to the opposing surfaces of the two limiting plates 41. One end of the spring 32 is connected to the middle periphery of the first connecting rod 31, and the other end is connected to the middle of the second connecting rod 33. One end of the second connecting rod 33 is movably sleeved on the periphery of the limiting rod 43, and the other end is sleeved on the periphery of the central shaft of the driven wheel assembly 2. A clearance groove is provided in the middle of the second connecting rod 33 corresponding to the spring 32. One end of the spring 32 passes through the clearance groove and is limited by a pin. When the cleaning trolley encounters a protruding area where a photovoltaic panel is docked during its movement, the photovoltaic panel presses against the driven wheel assembly 2, causing the spring 32 to be compressed. The second connecting rod 33 then rotates relative to the first connecting rod 31, and the height of the driven wheel assembly 2 is adjusted to adapt to the surface of the photovoltaic panel, ensuring that the track 5 always maintains the maximum contact area with the photovoltaic panel, preventing the track 5 from being partially suspended and slipping.
[0029] In optional embodiments, such as Figure 4 As shown, the handle 6 has a U-shaped structure, with its end extending through and connecting to the two limiting plates 41. The middle part of the handle 6 protrudes from one of the limiting plates 41. Specifically, the middle part of the handle 6, i.e., the gripping part, is located on the limiting plate 41 on the side away from the cleaning cart. The end of the handle 6 extends from the limiting plate 41 on that side to the limiting plate 41 on the other side and connects to it. Tracked walking mechanisms are mostly used in pairs. Therefore, when using a cleaning cart with a tracked walking mechanism, the worker uses its handle 6 to lift the cleaning cart from the transport tool and place it on the ground, providing a gripping point for convenient handling.
[0030] In optional embodiments, such as Figure 4 As shown, the central shaft of one of the driving wheels 1 is connected to the reinforcing plate 42 via a third connecting rod 8. Specifically, the driving wheel 1 on this side is composed of two driving wheels that share a central shaft for synchronous rotation. The third connecting rod 8 has a hole corresponding to the middle of its central shaft, and a bearing is provided on the hole wall. The third connecting rod 8, in conjunction with the reinforcing plate 42, ensures stable connection and smooth rotation of the driving wheel 1. Furthermore, the driven wheel assembly 2 includes two driven wheels, the central shafts of which are interconnected. The buffer component 3 is connected to the middle of the central shaft connecting the two driven wheels. The two driven wheels rotate autonomously and synchronously relative to the central axis in cooperation with the driving wheel 1 and the track 5. This ensures that there is sufficient contact surface between the driven wheel set 2 and the track 5, ensuring the stable operation of the track 5. When encountering road surfaces or photovoltaic panels with protrusions, the driven wheel set 2 can rotate relative to the limit rod 43 through the second connecting rod 33 to raise or lower the height of the driven wheel set 2 to adapt to the scene, reduce bumps, and keep the track 5 in contact with the ground or photovoltaic panel surface at all times.
[0031] Reference Figure 5 This utility model also proposes a photovoltaic panel cleaning vehicle 9, wherein the tracked walking mechanism is disposed on both sides of the photovoltaic panel cleaning vehicle 9. The specific structure of the tracked walking mechanism is as described in the above embodiments. Since this photovoltaic panel cleaning vehicle 9 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. The tracked walking mechanism is disposed on both sides of the vehicle body. In this embodiment, five sets of driven wheel sets 2 and buffer components 3 are provided, and they are equally spaced on the main frame 4. The photovoltaic panel cleaning vehicle 9 also includes a cleaning module 91, a GPS module, and a control module, etc., which work together with the tracked walking mechanism to continuously clean the surface of the photovoltaic panel.
[0032] In summary, the tracked walking mechanism is equipped with a buffer component 3 that allows for floating adjustment of the height of the driven wheel assembly 2, adapting to the position of the connecting protrusions of the two photovoltaic panels or the ground protrusions. This ensures that the track 5 always maintains the maximum contact area with the photovoltaic panel or the ground, preventing slippage caused by partial suspension of the track 5, enabling smooth walking and reducing bumps.
