[0048] Photovoltaic panels are devices that absorb sunlight and convert it directly or indirectly into electrical energy. Since PV panels primarily operate outdoors, snowy conditions can obscure the panels' surface, reducing their light-receiving area. Therefore, to ensure efficient power generation, snow covering the panels must be promptly cleared.

[0049] Currently, the existing photovoltaic module snow removal technology is generally carried out manually, with workers directly using handheld scrapers to clear the snow on the surface of the photovoltaic modules.

[0050] However, when using the above method to remove snow from photovoltaic modules, not only is the snow removal efficiency low, but the scraper is also likely to scratch the surface of the photovoltaic modules, resulting in a shortened service life of the photovoltaic modules.

[0051] Based on this, an embodiment of the present application provides a photovoltaic module snow removal device, which includes a support frame, a sliding mechanism, a support arm and a heating mechanism.

[0052] When the surface of the photovoltaic module is covered with snow, the sliding mechanism installed on the support frame is controlled to drive the support arm, and together with the heating mechanism installed at the end of the support arm, they slide along the extension direction of the support frame; at the same time, due to the rotational connection between the support arm and the sliding mechanism, the heating mechanism can adjust its posture according to the inclination angle of the photovoltaic module to ensure that the heating surface is in close contact with the surface of the photovoltaic module, thereby completing the snow removal operation on the surface of the photovoltaic module.

[0053] Therefore, the embodiment of the present application provides a sliding mechanism and a support arm so that the photovoltaic module snow removal device has the function of adjusting the spatial position of the heating mechanism, ensuring that the moving range of the heating mechanism can cover various positions on the surface of the photovoltaic module, and realizing automatic snow removal on the surface of the photovoltaic module, thereby improving the working efficiency of snow removal of the photovoltaic module.

[0054] The following detailed description of the technical solutions of the embodiments of the present application is given with reference to the accompanying drawings. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0055] Reference Figure 1 As shown, an embodiment of the present application provides a photovoltaic module snow removal device, including a support frame, a sliding mechanism 200, a support arm 300 and a heating mechanism; the support frame is located on one side of the photovoltaic module, and the sliding mechanism 200 is installed on the support frame and can slide along the extension direction of the support frame.

[0056] It should be noted that in the embodiment of the present application, there is no limitation on the specific arrangement of the support frame, which can be arranged in a horizontal or vertical direction. The staff can choose the specific arrangement according to the actual situation.

[0057] A heating mechanism is installed at one end of the support arm 300, and the other end of the support arm 300 is rotatably connected to the sliding mechanism 200 to drive the heating mechanism to rotate relative to the sliding mechanism 200; the heating mechanism is used to heat the photovoltaic module.

[0058] In an embodiment of the present application, when the surface of the photovoltaic module is covered with snow, the sliding mechanism 200 installed on the support frame is controlled to drive the support arm 300, together with the heating mechanism installed at the end of the support arm 300, to slide along the extension direction of the support frame; at the same time, due to the rotational connection between the support arm 300 and the sliding mechanism 200, the heating mechanism can adjust its own posture according to the inclination angle of the photovoltaic module to ensure that the heating surface of the heating mechanism is in close contact with the surface of the photovoltaic module, thereby completing the snow removal operation on the surface of the photovoltaic module.

[0059] Therefore, the embodiment of the present application provides a sliding mechanism 200 and a support arm 300, so that the photovoltaic module snow removal device has the function of adjusting the spatial position of the heating mechanism, ensuring that the moving range of the heating mechanism can cover various positions on the surface of the photovoltaic module, and realizing automatic snow removal on the surface of the photovoltaic module, thereby improving the working efficiency of snow removal of the photovoltaic module.

[0060] In some embodiments, a first toothed member 210 is provided on the sliding mechanism 200; a second toothed member 311 is provided at the end of the support arm 300 close to the sliding mechanism 200, and the first toothed member 210 and the second toothed member 311 are engaged with each other so that the support arm 300 can drive the heating mechanism to rotate relative to the sliding mechanism 200.

[0061] It is understood that in the embodiment of the present application, the specific transmission method between the sliding mechanism 200 and the support arm 300 is not limited, as long as it can ensure that the support arm 300 can drive the heating mechanism to rotate relative to the sliding mechanism 200. Specifically, in this embodiment, the sliding mechanism 200 and the support arm 300 are driven by gear meshing, which not only facilitates the assembly of the sliding mechanism 200 and the support arm 300, but also ensures reliable transmission between the sliding mechanism 200 and the support arm 300, thereby driving the heating mechanism to rotate relative to the photovoltaic module.

[0062] In some embodiments, the support arm 300 includes a first sleeve 310 and a second sleeve 320, the first sleeve 310 is sleeved on the outer peripheral side of the second sleeve 320, the second sleeve 320 is configured to be extended or retracted relative to the first sleeve 310, and the first sleeve 310 is rotatably connected to the sliding mechanism 200, and a heating mechanism is installed on the second sleeve 320.

[0063] Here, a first sleeve 310 and a second sleeve 320 are provided, and the second sleeve 320 is configured to be extendable or retractable relative to the first sleeve 310, so that the operator can adjust the spatial position of the heating mechanism in real time by controlling the extension distance of the second sleeve 320; at the same time, since the first sleeve 310 and the second sleeve 320 both have a certain length, the coverage range of the heating mechanism is further expanded.

[0064] Furthermore, in some embodiments, a first thread segment is provided on the inner wall of the first sleeve 310; a second thread segment matching the first thread segment is formed on the outer wall of the second sleeve 320, and the first sleeve 310 and the second sleeve 320 are threadedly connected via the first thread segment and the second thread segment.

[0065] It is understood that in the embodiment of the present application, the specific transmission method between the first sleeve 310 and the second sleeve 320 is not limited, as long as it can ensure that the second sleeve 320 can be extended or retracted relative to the first sleeve 310. Specifically, in this embodiment, the first sleeve 310 and the second sleeve 320 are transmitted via a thread, which not only facilitates the assembly of the first sleeve 310 and the second sleeve 320, but also makes the extension distance of the second sleeve 320 easier to control, avoiding the need for the operator to repeatedly adjust the position of the second sleeve 320 during operation.

[0066] In some embodiments, the support frame includes a support rod 100 and a column. The support rod 100 is a threaded rod, and the support rod 100 is installed between two adjacent columns; the sliding mechanism 200 is mounted on the support rod 100, and the sliding mechanism 200 and the support rod 100 are connected by threads.

[0067] It is understood that in the embodiment of the present application, there is no limitation on the specific transmission method between the support rod 100 and the sliding mechanism 200, as long as it can ensure that the sliding mechanism 200 can slide along the extension direction of the support rod 100. Specifically, in the present embodiment, the support rod 100 is a threaded rod, and the support rod 100 and the sliding mechanism 200 are transmitted through the thread, which not only facilitates the assembly between the support rod 100 and the sliding mechanism 200, but also makes the moving distance of the sliding mechanism 200 on the support rod 100 easier to control, thereby avoiding the need for the operator to repeatedly adjust the position of the sliding mechanism 200 during operation.

[0068] Furthermore, in some embodiments, a displacement sensor is provided on the support rod 100 to detect the displacement of the sliding mechanism 200 on the support rod 100 .

[0069] Since the displacement sensor has the function of real-time monitoring and recording the displacement of an object, a displacement sensor is provided on the support rod 100 to accurately control the position of the sliding mechanism 200 on the support rod 100. This not only avoids the heating mechanism from repeatedly performing snow removal operations on the same position on the photovoltaic module, resulting in energy waste; it also prevents a certain position on the photovoltaic module from being missed during the snow removal operation, resulting in incomplete snow removal operations.

[0070] In some embodiments, a mounting bracket 500 is further included; the mounting bracket 500 is located between the support arm 300 and the heating mechanism, and both sides of the mounting bracket 500 are respectively connected to the support arm 300 and the heating mechanism to fix the heating mechanism on the support arm 300.

[0071] In the specific implementation, the mounting bracket 500 has a certain elasticity. On the one hand, it can absorb part of the vibration caused by the sliding mechanism 200 sliding on the support frame and the rotation of the support arm 300 relative to the sliding mechanism 200, thereby ensuring the stability of the heating mechanism during the snow removal operation; on the other hand, due to the limitations of the rotation between the support arm 300 and the sliding mechanism 200, it is difficult for the posture of the heating mechanism to be exactly the same as the inclination angle of the photovoltaic module. The certain elasticity of the mounting bracket 500 can ensure that the heating surface of the heating mechanism fits tightly with the surface of the photovoltaic module, thereby improving the snow removal efficiency of the photovoltaic module.

[0072] Furthermore, in some embodiments, the heating mechanism includes a heating gasket 400; the mounting bracket 500 includes a first mounting bracket 510 and a second mounting bracket 520, and there is an angle between the first mounting bracket 510 and the second mounting bracket 520, and the first mounting bracket 510 and the second mounting bracket 520 are fixedly connected to the support arm 300 and the heating gasket 400, respectively.

[0073] Here, a first mounting bracket 510 and a second mounting bracket 520 are provided to fix and connect different positions on the heating gasket 400 , thereby reducing the impact of the external environment on the heating gasket 400 during the snow removal operation and improving the stability of the heating gasket 400 .

[0074] Furthermore, in some embodiments, a position sensor is provided on the heating pad 400 to monitor the relative position between the heating pad 400 and the photovoltaic assembly.

[0075] Since the position sensor has the function of detecting and tracking the position of an object in real time, a position sensor is set on the heating gasket 400 to accurately control the relative position between the heating gasket 400 and the photovoltaic module. This can not only maintain close contact between the heating gasket 400 and the photovoltaic module, ensuring the snow removal efficiency of the photovoltaic module snow removal device; at the same time, it can prevent the heating gasket 400 from continuing to move after contacting the photovoltaic module, which will cause the heating gasket 400 and the photovoltaic module to be squeezed against each other, causing structural damage.

[0076] In some embodiments, a temperature sensor is further provided on the heating pad 400 to monitor the surface temperature of the heating pad 400 .

[0077] Since the temperature sensor has the function of detecting the temperature of an object in real time, a temperature sensor is set on the heating gasket 400 to accurately control the heating temperature of the heating gasket 400. While ensuring the snow removal efficiency, it prevents the heating temperature of the heating gasket 400 from being too high, causing damage to the surface of the photovoltaic module.

[0078] It should be understood that the various forms of processes shown above can be used to reorder, add, or delete steps. For example, the steps described in the embodiments of the present application can be performed in parallel, sequentially, or in a different order, as long as the desired results of the technical solutions disclosed in the embodiments of the present application can be achieved, and this document is not limited here.

[0079] The above specific implementation manner does not constitute a limitation on the protection scope of the embodiments of the present application. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations, and substitutions can be made based on design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the principles of the embodiments of the present application should be included in the protection scope of the embodiments of the present application.
