Abstract
Description
Technical Field
[0001] This utility model relates to the field of photovoltaic cleaning technology, and in particular to a track wheel and a photovoltaic cleaning robot. Background Technology
[0002] A photovoltaic (PV) power generation array is a system that combines multiple photovoltaic modules arranged according to certain rules to convert solar energy into electrical energy through the photoelectric effect. Its core components include photovoltaic cells, support structures, combiner boxes, and inverters. Its working principle is that semiconductor materials absorb photons to generate direct current (DC), which is then converted into alternating current (AC) by the inverter and fed into the power grid.
[0003] Over time, photovoltaic (PV) panels easily accumulate dust, snow, bird droppings, and other contaminants. This contamination can obstruct certain areas of the panel, preventing them from receiving sufficient sunlight. This reduces the panel's power generation efficiency. Furthermore, these areas, unable to generate electricity, act as resistance compared to other areas, leading to abnormal overheating during operation. Therefore, regular cleaning of PV panels is essential to improve power generation efficiency and extend their lifespan.
[0004] To improve cleaning efficiency, photovoltaic (PV) arrays are typically equipped with PV cleaning robots. In practical applications, some PV arrays are quite long, reaching over ten or even twenty meters. A single PV cleaning robot cannot span such a large area. This makes cleaning large PV arrays quite difficult for PV cleaning robots. Utility Model Content

[0022] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0023] Example 1:
[0024] A track wheel includes: a traveling wheel 1 and a guide wheel 2. The traveling wheel 1 is mounted on a photovoltaic panel and is in contact with the photovoltaic panel. The guide wheel 2 is disposed on one side of the traveling wheel 1. The diameter of the guide wheel 2 is larger than the diameter of the traveling wheel 1. The axial length of the guide wheel 2 corresponds to the gap between the photovoltaic panels, so as to extend into the gap.
[0025] In practical applications, the traveling wheel 1 is in contact with the photovoltaic panel, enabling the photovoltaic cleaning robot to move along the panel. Conversely, the axis of the guide wheel 2 corresponds to the gap between the photovoltaic panels, allowing it to extend into the gap. Thus, the guide wheel 2 uses the gap between the photovoltaic panels to limit the travel wheel 1, effectively preventing the photovoltaic cleaning robot from slipping off the panel and restricting its movement from one end of the panel to the other. Therefore, a large photovoltaic array can be cleaned by multiple photovoltaic cleaning robots working together or by a single robot cleaning each row sequentially.
[0026] The traveling wheel 1 has a weight-reducing groove 11. The traveling wheel 1 also has an assembly structure 12. The assembly structure 12 extends into the weight-reducing groove 11 from the side of the traveling wheel 1 away from the guide wheel 2. The assembly structure 12 also has an assembly hole 121. The assembly hole 121 coincides with the axis of the traveling wheel 1 and penetrates the assembly structure 12.
[0027] In practice, the traveling wheel 1 reduces its overall weight through the weight-reduction groove 11. At the same time, the connecting rod of the photovoltaic cleaning robot used to assemble the wheel can be inserted into the assembly structure 12 through the assembly hole 121, thereby assembling it together with the traveling wheel 1 through the assembly structure 12.
[0028] On the other hand, the guide wheel 2 is provided with a guide ramp 21. The guide ramp 21 is inclined from the outer edge of the guide wheel 2 toward the axis of the guide wheel 2. There are two guide ramps 21. The guide ramps 21 are arranged symmetrically between them.
[0029] Even if the length of the photovoltaic cleaning robot is shortened to an acceptable range using guide wheels 2, a certain gap will still exist between its two ends. This results in a difference in the travel speed between the two ends of the photovoltaic cleaning robot due to installation errors or other external factors. Consequently, the outer edge of guide wheels 2 will abut against the side wall of the photovoltaic panel during travel. At this point, because guide wheels 2 are equipped with guide ramps 21, after abutting against the side wall of the photovoltaic panel, guide wheels 2 tend to slide into the gap between the photovoltaic panel and the guide ramps 21. This makes it easier to correct the travel state of the photovoltaic cleaning robot and prevent it from deviating during travel. Preferably, guide wheels 2 can be made of nylon material, which provides a certain degree of elasticity, thus facilitating the aforementioned correction process.
[0030] The guide wheel 2 also has a pin hole 22. The pin hole 22 passes through the guide wheel 2. The pin hole 22 coincides with the axis of the traveling wheel 1. At the same time, the traveling wheel 1 and the guide wheel 2 have weight-reducing holes 3. The weight-reducing holes 3 pass through the traveling wheel 1. The weight-reducing holes 3 pass through the guide wheel 2.
[0031] The connecting rod of the photovoltaic cleaning robot can be connected to other structures of the photovoltaic cleaning robot through the pin hole 22 on the guide wheel 2. On the other hand, the weight reduction hole 3 can effectively reduce the weight of the guide wheel 2.
[0032] Example 2:
[0033] A photovoltaic cleaning robot includes: track wheels as described in Embodiment 1; and a cleaning roller 6. The cleaning roller 6 is mounted on a photovoltaic panel. Track wheels are respectively disposed on both sides of the cleaning roller 6 to drive the cleaning roller 6 from one end of the photovoltaic panel to the other. Specifically, it also includes a traveling structure 4. The traveling structure 4 includes a traveling motor 41, a connecting rod 42, a transmission gear 43, and a transmission belt 44. The end of the connecting rod 42 is connected to the track wheels. The connecting rod 42 is respectively disposed on both sides of the cleaning roller 6. The transmission gear 43 is connected to one end of the connecting rod 42. The transmission belt 44 is sleeved on the transmission gear 43. The traveling motor 41 is connected to one of the transmission gears 43. It also includes a cleaning motor 5. The cleaning motor is connected to the cleaning roller 6.
[0034] In actual operation, the photovoltaic cleaning robot is mounted entirely on the photovoltaic panel, ensuring that the cleaning roller 6 is in close contact with the panel. Simultaneously, the track wheels are embedded in the gaps between the photovoltaic panels. The travel motor 41 is activated, driving the corresponding transmission gear 43 to rotate, which in turn drives another transmission gear 43 via the transmission belt 44. When the transmission gear 43 rotates, it drives the connecting rod 42 to rotate synchronously, which in turn drives the corresponding track wheels to rotate. Thus, the track wheels drive the entire structure to move synchronously along the photovoltaic panel. Simultaneously, the cleaning motor 5 is activated, driving the cleaning roller 6 to rotate continuously, thereby cleaning the photovoltaic panel as the track wheels drive the entire structure to move along the panel. Preferably, the transmission belt 44 has grooves corresponding to the transmission gear 43 for meshing.
[0035] On the other hand, because the track wheels can be embedded in the gaps between the photovoltaic panels, they can effectively limit and guide the movement, thus enabling a large photovoltaic power generation array to be cleaned by multiple photovoltaic cleaning robots working together or by a single photovoltaic cleaning robot cleaning row by row.
