Description

Technical Field

[0001] The present disclosure relates to the technical field of snow removal systems, and in particular to a photovoltaic panel graded snow removal system for mine slope monitoring. Background Art

[0002] Mine slope monitoring is crucial to the safe production of open-pit mining, and mainly includes two methods: surface displacement monitoring and deep-hole displacement monitoring. Among them, deep-hole displacement monitoring uses deep-hole inclinometers to monitor the horizontal displacement of underground rock layers. Deep-hole inclinometers usually rely on photovoltaic panels to convert solar energy into electricity to power the entire system. Although photovoltaic panels effectively solve the problem of power supply difficulties in remote areas of open-pit mines through the green energy of solar energy, in winter or at high altitudes, snow on the surface of photovoltaic panels not only covers the photovoltaic panels and directly blocks sunlight, affecting the photovoltaic panels' effective reception of sunlight and photoelectric conversion, thus limiting the panels' power generation efficiency, but also long-term snow accumulation will cause structural deformation due to freeze-thaw cycles, thus affecting the life of the components. In severe cases, it may cause the entire photovoltaic panel to collapse. On the one hand, the damage to the photovoltaic panels will stop the power supply, resulting in the interruption of the mine slope monitoring system, threatening the safety of open-pit mine production. On the other hand, the damage to the photovoltaic panels and its impact on the production process of the open-pit mine will cause huge economic losses to the mine.

[0003] Removing snow from photovoltaic panels has become a research focus. Currently, manual snow removal is the primary method for removing snow from photovoltaic panels. Mechanical snow removal and nano-self-cleaning coatings are also commonly used. However, manual snow removal can easily damage photovoltaic panels, while mechanical snow removal equipment is complex and difficult to operate, and is also prone to damage during heavy snow. Nano-self-cleaning coatings are expensive, making them difficult to widely use. Utility Model Content

[0024] Example

[0025] like Figure 1-2 As shown, this embodiment provides a photovoltaic panel 2 graded snow removal system for mine slope monitoring, including a fixing frame 1, the surface of the fixing frame 1 is inclined, the surface of the fixing frame 1 is embedded with a photovoltaic panel 2, the surface of the fixing frame 1 is provided with a detection device 4 for detecting the thickness of snow on the photovoltaic panel 2, and then responding to different snow removal devices according to different snow thicknesses, the surface of the fixing frame 1 is located on one side of the photovoltaic panel 2 and is provided with a snow blowing device 5, the snow blowing device 5 is used to blow snow off the photovoltaic panel 2 when there is not much snow, and the back of the photovoltaic panel 2 A self-heating snow removal device 6 and a vibration device 7 are provided. The self-heating snow removal device 6 and the vibration device 7 are used to cooperate with the snow blowing device 5 to remove snow when there is a lot of snow. The surface of the fixed frame 1 is provided with a snow scraper 8 at one end of the photovoltaic panel 2. The snow scraper 8 is used to clear the snow when the snow is very deep. The surface of the fixed frame 1 is fixedly connected to an electric control box 3. The electric control box 3 is respectively connected to the photovoltaic panel 2, the detection device 4, the snow blowing device 5, the self-heating snow removal device 6, the vibration device 7 and the snow scraper 8 through wires.

[0026] Specifically, the detection device 4 includes a mounting bracket 41 and a detection sensor 42. The mounting bracket 41 is an "L"-shaped structure. The bottom of the mounting bracket 41 is fixed to the surface of the fixing frame 1 by bolts. The top of the mounting bracket 41 extends above the photovoltaic panel 2 and is fixedly connected to the detection sensor 42. The detection sensor 42 is a sensor that can detect the depth of snow, such as an ultrasonic snow depth sensor or a laser snow depth meter. The detection sensor 42 is connected to the electrical control box 3 by a wire. The detection sensor 42 detects the thickness of snow on the surface of the photovoltaic panel 2 and sends the detected information to the electrical control box 3. The electrical control box 3 is equipped with a power supply and a controller that drives the operation of various devices. The electrical control box 3 controls the operation of different devices to perform snow removal operations based on the detected snow thickness.

[0027] Furthermore, there are two detection devices 4, which are respectively arranged at both ends of the photovoltaic panel 2. By performing detection with two detection devices 4, the detection position is more comprehensive.

[0028] Specifically, the snowblowing device 5 includes a blower 51 and a blowpipe 52. The blower 51 and blowpipe 52 are respectively fixedly connected to the surface of the fixing frame 1. The output end of the blower 51 is connected to the input end of the blowpipe 52. The blowpipe 52 is arranged along the length of the photovoltaic panel 2. The blowpipe 52 has multiple blowout ports 53 on the side close to the photovoltaic panel 2. The blower 51 is connected to the electrical control box 3 via a wire. When the detection device 4 detects that snow has begun to accumulate on the surface of the photovoltaic panel 2, the electrical control box 3 controls the blower 51 to operate. The wind blown by the blower 51 passes through the blowpipe 52 and is blown out from the multiple blowout ports 53. The strong wind force blows the snowflakes off the photovoltaic panel 2.

[0029] Specifically, the self-heating snow removal device 6 includes a plurality of heating strips 61 fixedly connected to the back of the photovoltaic panel 2. The plurality of heating strips 61 are parallel to the width of the photovoltaic panel 2 and are evenly spaced. The plurality of heating strips 61 are connected to the electrical control box 3 via wires. In this embodiment, there are five heating strips 61, evenly spaced from top to bottom on the back of the photovoltaic panel 2. When the detection device 4 detects that the thickness of the snow reaches 3 cm, the electrical control box 3 supplies power to the heating strips 61, which generate heat to melt the snow on the surface of the photovoltaic panel 2, thereby accelerating snow removal.

[0030] Specifically, the vibration device 7 includes a plurality of vibrators 71, each of which is fixedly connected to the back of the photovoltaic panel 2. The vibrators 71 are connected to the electrical control box 3 via wires. In this embodiment, the vibrators 71 may be vibration motors. When the snow thickness is greater than 3 cm, the heating strips 61 generate heat to melt the snow on the surface of the photovoltaic panel 2, reducing the friction between the snow and the photovoltaic panel 2. At the same time, the vibrators 71 vibrate to shake off the snow.

[0031] Specifically, the snow scraper device 8 includes a cylinder mounting plate 81, a snow scraper cylinder 82, and a snow scraper blade 83. The mounting plate 81 of the snow scraper cylinder 82 is fixedly connected to the surface of the fixed frame 1. The snow scraper cylinder 82 is fixedly connected to the cylinder mounting plate 81. The output shaft of the snow scraper cylinder 82 is fixedly connected to the side of the snow scraper blade 83. The bottom of the snow scraper blade 83 has a clearance fit with the photovoltaic panel 2. When the thickness of the snow exceeds 5 cm, the snow scraper cylinder 82 pushes the snow scraper blade 83 toward the photovoltaic panel 2, with the bottom of the snow scraper blade 83 and the surface of the photovoltaic panel 2 being 0.5 cm apart. The snow scraper blade 83 pushes the snow off the surface of the photovoltaic panel 2, and cooperates with the snow blowing device 5, the self-heating snow removal device 6, and the vibration device 7 to remove the snow.

[0032] Furthermore, the surface of the fixing frame 1 is provided with chutes 85 on both sides of the photovoltaic panel 2. Rollers 84 are rotatably connected to the bottom of the snow scraper 83 at positions corresponding to the chutes 85 on both sides, and the bottoms of the rollers 84 are embedded in the chutes 85. The rollers 84 support the snow scraper 83 and slide within the chutes 85, acting as a guide, so that the snow scraper 83 can remain suspended 0.5 cm above the photovoltaic panel 2.

[0033] Furthermore, a spring mounting plate 86 is fixedly connected to the surface of the fixing frame 1. A return spring 87 is fixedly connected to the side of the spring mounting plate 86 near the snow scraper 83. One end of the return spring 87 is fixedly connected to the snow scraper 83. When the snow scraper 83 is driven by the snow scraping cylinder 82 to scrape snow, the return spring 87 is stretched. When the snow scraper 83 returns, the return spring 87 rebounds, assisting the return of the snow scraper 83.

[0034] The working principle of the present invention is as follows: the depth of snow on the surface of the photovoltaic panel 2 is detected by the detection device 4, and different devices are used to remove snow according to different depths. When the snowfall is small, the photovoltaic panel 2 is just beginning to be covered with snow. At this time, the blower 51 is controlled by the electric control box 3 to work, and the wind blown by the blower 51 passes through the blower pipe 52 and is blown out from multiple blower ports 53. The strong wind blows the snowflakes off the photovoltaic panel 2; when the snowfall is large, the detection device 4 detects that the snow thickness is greater than 3 cm, the heating strip 61 heats up and melts the snow on the surface of the photovoltaic panel 2, reducing the friction between the snow and the photovoltaic panel 2, and at the same time vibrates through the vibrator 71 to shake off the snow; when the snowfall is large and the snow thickness is greater than 5 cm, the snow scraping cylinder 82 pushes the snow scraper 83 towards the direction close to the photovoltaic panel 2, and the distance between the bottom of the snow scraper 83 and the surface of the photovoltaic panel 2 is 0.5 cm. The snow scraper 83 pushes the snow on the surface of the photovoltaic panel 2, and cooperates with the snow blowing device 5, the self-heating snow removal device 6 and the vibration device 7 to remove snow.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure, rather than to limit them. Although the present disclosure has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present disclosure.
