Description

Technical Field

[0001] This invention relates to the field of metrological verification technology, and more specifically, to a solar panel cleaning device. Background Technology

[0002] The production processes of various industries are inseparable from the use of water and electricity, and the cigarette industry is no exception. Daily washing and cleaning require relatively little water; however, after production ends, cigarette equipment needs to be cleaned promptly, requiring a large amount of hot water in a short period. Considering these water usage characteristics, to improve energy efficiency, the cigarette industry's hot water heating system primarily uses solar energy, supplemented by heat exchangers, to meet the needs of daily life and production.

[0003] Solar panels are devices that absorb sunlight and convert solar radiation energy directly or indirectly into electrical energy through the photoelectric effect or photochemical effect. Compared with ordinary batteries and rechargeable batteries, solar cells are more energy-efficient and environmentally friendly green products. In addition to the material of the solar cell itself, the most significant factor affecting the conversion efficiency of a solar cell is the light transmittance of the glass surface. Solar panels are usually installed outdoors, and over time, dust accumulates on the glass surface of the panels, reducing light transmittance. This causes the panels to fail to generate electricity before reaching their lifespan. Therefore, solar panels need to be cleaned regularly to remove surface dust and dirt in order to generate electricity effectively. Currently, solar panel cleaning mainly relies on large cleaning trucks or manual cleaning, which is costly or inefficient.

[0004] Therefore, how to provide a device that can effectively clean solar panels has become a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0026] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the invention.

[0027] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0028] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0029] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0030] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0031] according to Figures 1 to 4 As shown, the present invention provides a solar panel cleaning device, including a base frame 1 and a dual cleaning mechanism 2; the base frame 1 has a cleaning hole in the middle, which corresponds to the surface of the solar panel.

[0032] The dual cleaning mechanism 2 includes a first motor 201, a threaded rod 203, a slider 202, an adsorption cylinder 205, and a cleaning brush 206; support plates are provided on opposite sides of the cleaning holes, and corresponding grooves are provided on the support plates; the first motor 201 is located on the outside of one of the support plates, the threaded rod 203 is connected to the output end of the first motor 201, and the slider 202 is threadedly sleeved on the threaded rod 203.

[0033] The adsorption cylinder 205 has a first rotating shaft 204 rotatably connected at its axis. One end of the first rotating shaft 204 and the cleaning brush 206 pass through one of the slides and are connected to the slider 202. The other end passes through another slide and is fixedly connected by the limiting strip 207. The cleaning brush 206 is located on the front side of the adsorption cylinder 205. The cleaning brush 206 is used to clean the surface of the solar panel, and the adsorption cylinder 205 is used to adsorb the dust that has been cleaned.

[0034] In this embodiment, the base frame 1 is placed on the solar panel, with the cleaning hole facing the surface of the solar panel to be cleaned. Then, the first motor 201 is started, which drives the threaded rod 203 to rotate. The threaded rod 203 drives the slider 202 to move on the threaded rod 203 through the threaded connection, thereby driving the cleaning brush 206 and the adsorption roller to move. The cleaning brush 206 is located on the front side, which sweeps the dust on the surface of the solar panel and removes it from the surface of the solar panel. The adsorption cylinder 205 is located on the rear side, which adsorbs the dust swept down by the cleaning brush 206 by rolling, so as to complete the cleaning of the surface of the solar panel.

[0035] Furthermore, the end of the threaded rod 203 furthest from the first motor 201 is also provided with a rotatably connected bearing seat 208, which is fixed to the base frame 1. The threaded rod 203 is supported by the bearing seat 208 and the first motor 201, preventing the slider 202 from moving to the end of the threaded rod 203 and preventing the output shaft of the first motor 201 from effectively supporting the weight of the threaded rod 203.

[0036] Furthermore, it also includes a cylindrical cleaning mechanism 3, which includes a second motor 303 and a cleaning cylinder 302. The second motor 303 is disposed on the outside of one of the support plates. A second rotating shaft 301 is provided at the axis of the cleaning cylinder 302, and the two ends of the second rotating shaft 301 are respectively rotatably connected to the support plate, and one end of the second rotating shaft 301 is connected to the output end of the second motor 303. The cleaning cylinder 302 and the adsorption cylinder 205 are arranged in parallel on opposite sides of the cleaning hole, and are used to clean the dust on the adsorption cylinder 205. In this embodiment, since the dual cleaning mechanism 2 cleans the surface of the solar panel, in order to improve the cleaning efficiency, the same cleaning device needs to clean multiple solar panels, which will seriously increase the burden on the adsorption cylinder 205, thereby reducing the cleaning quality of the subsequent solar panels. In this invention, a cleaning cylinder 302 is provided on the other side of the cleaning hole located on the adsorption cylinder 205. When the adsorption cylinder 205 moves to the position of the adsorption cylinder 205 as the threaded rod 203 rotates, the second motor 303 drives the cleaning cylinder 302 to rotate, thereby adsorbing the dust on the adsorption cylinder 205 onto the cleaning cylinder 302, so that the adsorption cylinder 205 can clean the next solar panel.

[0037] Furthermore, the base frame 1 is also provided with a partition near the end of the cleaning cylinder 302. A brush plate 304 is provided on the inner side of the partition facing the cleaning cylinder 302, used to remove dust from the cleaning cylinder 302. In this embodiment, as mentioned above, the cleaning cylinder 302 can adsorb dust from the adsorption cylinder 205, allowing the device to clean multiple solar panels. However, there is an upper limit to the amount of dust that the cleaning cylinder 302 can adsorb. This invention uses the brush plate 304 to remove dust from the cleaning cylinder 302, thereby reducing the burden on the cleaning cylinder 302. Additionally, to prevent the brush plate 304 from scraping dust from the cleaning cylinder 302 onto the solar panels, the cleaning hole near the cleaning cylinder 302 should extend beyond the solar panels, allowing the brush plate 304 to scrape the dust from the cleaning cylinder 302 onto the ground for centralized processing, ensuring the equipment can operate for a longer period. This dual automatic cleaning system provides high cleaning efficiency. Of course, in order to improve the cleaning efficiency of dust, the present invention can also provide a collection frame or other structure on the bottom surface of the base frame 1 near the cleaning cylinder 302 to collect the dust scraped off from the cleaning cylinder 302.

[0038] Furthermore, the cleaning cylinder 302 is positioned at a horizontal level above the adsorption cylinder 205. This ensures that the adsorption cylinder 205 can move completely over the solar panel, guaranteeing thorough cleaning of the solar panel.

[0039] Furthermore, it also includes an adjusting and moving mechanism 4, which includes a roller bracket 404 and rubber wheels 405. The roller bracket 404 is located at the corner of the base frame 1, and the rubber wheels 405 are rotatably connected to the lower side of the roller bracket 404, with their sidewalls adhering to the edge of the solar panel to limit the position of the base frame 1. In this embodiment, the first motor 201 drives the threaded rod 203 to rotate, and the second motor 303 drives the cleaning cylinder 302 to rotate. The operation of both will produce a certain vibration effect, which will cause the base frame 1 to be unable to be stably placed on the solar panel. In order to ensure the cleaning quality of the solar panel, the present invention uses multiple rubber wheels 405 to adhere to the edge of the solar panel, thereby limiting the position of the base frame 1 and preventing the operation of the first motor 201 and the second motor 303 from causing displacement of the base frame 1.

[0040] Furthermore, the base frame 1 is provided with multiple sets of sliding bases 401 on both outer sides of the support plate. The roller bracket 404 is provided with horizontal sliding rods 402, each sliding rod 402 slidably connected to a corresponding set of sliding bases 401. All sliding rods 402 are parallel to each other, allowing the roller brackets 404 to move closer or further apart, and their sidewalls to conform to the edges of solar panels of different sizes. In this embodiment, the position of the roller bracket 404 relative to the base frame 1 can be adjusted via the sliding rods 402, enabling the device to adapt to various sizes of solar panels and ensuring that the sidewalls of the rubber wheels 405 conform to the edges of different solar panels.

[0041] Furthermore, each set of sliding bases 401 consists of two units. A fixing screw 403 is provided on the portion of the slide rod 402 located between the two sliding bases 401 in the same set. The fixing screw 403 abuts against the surface of the base frame 1, thereby fixing the position of the roller bracket 404. As mentioned above, the roller bracket 404 and rubber wheel 405 restrict the position of the base frame 1, preventing displacement due to the operation of the first motor 201 and the second motor 303. However, due to the slidability of the slide rod 402 and the sliding base 401, this invention locks the slide rod 402 with the fixing screw 403, effectively preventing the slide rod 402 from sliding due to the operation of the first motor 201 and the second motor 303.

[0042] Furthermore, as mentioned above, the present invention can clean multiple solar panels. In order to improve cleaning efficiency, the movement of the base frame 1 also needs to be effectively improved. The adjustment and movement mechanism 4 also includes multiple moving wheels 5. The moving wheels 5 are set on the lower surface of the base frame 1 and can roll on the surface of the solar panels so as to drive the base frame 1 to move as a whole.

[0043] Furthermore, the adjusting and moving mechanism 4 also includes a lithium battery 7 and a control motherboard 6. Both the control motherboard 6 and the lithium battery 7 are located on the lower surface of the base frame 1. The control motherboard 6 is used to drive the starting and stopping of the moving wheels 5, and the lithium battery 7 provides power to the control motherboard 6. In this embodiment, the overall automation level of the invention is improved by using the control motherboard 6 and the lithium battery 7, eliminating the need for manual pushing of the base frame 1 and reducing manual labor. In addition, the control motherboard 6 should also be electrically connected to the first motor 201 and the second motor 303, thereby driving the operation of the first motor 201 and the second motor 303 through the control motherboard 6.

[0044] While specific embodiments of the invention have been described in detail by way of examples, those skilled in the art should understand that the examples are for illustrative purposes only and not intended to limit the scope of the invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the invention. The scope of the invention is defined by the appended claims.
