Description

Technical Field

[0001] The present invention relates to the technical field of snow removal devices, and in particular to a photovoltaic panel snow removal device and a use method thereof. Background Art

[0002] Photovoltaic panels are key devices that convert solar energy into electrical energy. Their normal operation is crucial to the power generation efficiency of the entire photovoltaic system. However, among the many factors that affect the performance of photovoltaic panels, snow accumulation is an issue that cannot be ignored.

[0003] Many high-latitude areas or cold climate regions have frequent snowfall in winter. When snow falls on the surface of photovoltaic panels, it will have many negative effects, directly leading to a sharp decrease in the power generation of photovoltaic panels. Secondly, the snow accumulates on photovoltaic panels for a long time, and its weight may cause physical damage to the photovoltaic panels. Photovoltaic panels are usually composed of multiple layers of materials and have a certain load-bearing limit. Excessive snow weight may cause photovoltaic panels to deform, crack, or even damage the internal cells and circuit connections, increasing maintenance and replacement costs.

[0004] A large area of ​​photovoltaic panels is covered with snow at the same time. If the snow cannot be removed in time and effectively, the entire power generation capacity will drop significantly and the photovoltaic panels will be easily damaged. Therefore, it is extremely necessary to remove snow from photovoltaic panels. In view of this, we propose a photovoltaic panel snow removal device. Summary of the invention

DETAILED DESCRIPTION

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0033] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0034] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it an embodiment that is mutually exclusive with other embodiments, either individually or selectively.

[0035] Example 1, reference Figure 1~Figure 3 , which is the first embodiment of the present invention, provides a photovoltaic panel snow removal device, which includes a support component 100, a snow melting component 200 and a snow sweeping component 300.

[0036] Specifically, the support assembly 100 includes a support vertical frame 102 with a mounting frame 101 mounted on the upper end, and a crossbeam frame 103 mounted on the mounting frame 101; the snow melting assembly 200 is mounted on both sides of the mounting frame 101 and located below the photovoltaic panel; the snow sweeping assembly 300 includes a mobile pallet 301 mounted on the mounting frame 101, and a mobile unit 302 movably mounted in the mobile pallet 301; The crossbeam frame 103 is used to support and fix the photovoltaic panel. In this embodiment, the installation angle of the photovoltaic panel body is set at an angle of 45°. The snow melting component 200 is used to provide a heat source to melt the frozen snow. The mobile support plate 301 is used to fix the snow melting component 200. The mobile unit moves repeatedly on the photovoltaic panel to scrape off the remaining snow on the photovoltaic panel.

[0037] Example 2, reference Figure 1 to Figure 12 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0038] Specifically, the snow melting assembly 200 includes a heating chamber 201 with an electric heating wire installed inside, and the heating chamber 201 is detachably mounted on the mounting frame 101 through a lug 201a provided therein; It is worth noting that in this embodiment, the heating chamber 201 is filled with heating liquid to prevent the electric heating wire from burning dry. The power supply of this embodiment is connected to the power storage module of the photovoltaic panel. This part of the power connection technology belongs to the existing technology, so it will not be explained in detail.

[0039] Specifically, a heat storage bin 202 is installed near the photovoltaic panel side of the heating bin 201, and a heat storage chamber 202a is provided in the heat storage bin 202; and a heat storage filler is provided in the heat storage chamber 202a.

[0040] Specifically, the heat storage filler is any one of alumina ceramic filler particles, zirconia ceramic filler particles, copper particles, and aluminum particles; It is worth noting that the heat storage filler in this embodiment uses alumina ceramic filler particles, which have a high melting point and good thermal stability, can absorb and store a large amount of heat, and the thermal conductivity of the alumina ceramic filler particles is relatively high, which enables it to quickly absorb and conduct heat, allowing it to absorb heat and conduct heat to the external photovoltaic panel body 3.

[0041] like Figure 3 , Fig.12 It can be seen that the heat storage bin 202 is close to the back of the photovoltaic panel, and will preheat the panel during the outward heat conduction process, and avoid the problem of local high temperature caused by installing heating wires directly on the panel. It can impact the back of the photovoltaic panel with a uniform heat flow, so that melted snow is formed between the surface snow and the panel, and then the snow will slide off in large pieces.

[0042] Specifically, a conducting hole 201b is provided between the heating chamber 201 and the heat storage chamber 202, which conducts heat to the heat storage filler in order to more fully perform heat exchange.

[0043] Specifically, the moving unit 302 includes a moving block 302a provided with a threaded hole 302b, and a mounting connecting rod 302c is provided on the moving block 302a. The brush rollers 303 are detachably mounted on both sides of the mounting connecting rod 302c.

[0044] Specifically, a threaded rod 304a is installed on the movable support plate 301 to rotate through a driving motor 304, and the movable block 302a is threadedly installed on the threaded rod 304a through a threaded hole 302b; The threaded rod 304a is driven to rotate by the driving motor 304, and then the moving block 302a can be moved back and forth along the rod body, so as to keep the brush roller 303 moving along the surface of the photovoltaic panel to sweep the snow.

[0045] Specifically, the moving block 302a is provided with an inserting cavity 302d, and the mounting connecting rod 302c is detachably mounted in the inserting cavity 302d.

[0046] Specifically, a clamping block 305 is inserted into the inserting cavity 302d, and a pressing plate 302e is detachably mounted on the moving block 302a.

[0047] Specifically, a vertically arranged guide block 305 a is provided on the clamping block 305 , and a plug hole 302 f for inserting the guide block 305 a is provided on the pressing plate 302 e ; a spring 305 b is sleeved on the guide block 305 a .

[0048] It is worth noting that the device in this embodiment operates periodically, not continuously, and the thickness of the accumulated snow is different. In order to avoid the problem that the brush roller 303 hard contacts the surface of the photovoltaic panel when the frozen snow is solidified and causes damage, the guide block 305a and the socket 302f are provided so that the block 305 can move up and down in the socket cavity, and the spring 305b ensures that the bottom of the block 305 is always in contact with the mounting rod 302c, ensuring that the brush roller 303 has the pressure required for sweeping the snow. When the brush roller 303 encounters a solid block of snow, the mounting rod 302c will be adaptively lifted to squeeze the spring 305b, thereby avoiding hard contact with the photovoltaic panel.

[0049] Example 3, reference Figure 1 to Figure 12 , which is the third embodiment of the present invention, and this embodiment provides a method for using a photovoltaic panel snow removal device, comprising the following steps: turning on the snow melting component 200 to form melted snow between the surface snow and the panel body, and then the snow will slide off; turning on the drive motor 304, the brush roller 303 moves up and down to sweep the remaining snow on the photovoltaic panel; when the brush roller 303 encounters a hard object, the guide block 305a moves up, so that the brush roller 303 moves up and does not make hard contact with the surface of the photovoltaic panel.

[0050] When in use, heating the photovoltaic panel first can, on the one hand, make the accumulated snow slide off, and on the other hand, can effectively reduce the freezing and compaction of snow on the photovoltaic panel, providing convenience for the subsequent snow removal of the snow-clearing assembly 300, further avoiding the hard contact between the brush roller 303 and the surface of the photovoltaic panel, and improving the safety of the device.

[0051] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
