Description

Technical Field

[0001] This utility model relates to the technical field of photovoltaic panel cleaning devices, specifically a cleaning device for solar photovoltaic panels. Background Technology

[0002] Currently, photovoltaic (PV) modules and solar PV panels are widely used due to their environmental friendliness. PV modules are structural units for photovoltaic power generation composed of solar cells, commonly known as solar PV panels. They are the core component for generating electricity using solar energy. Extensive production practice shows that after a period of use, PV modules placed outdoors are prone to accumulating dust and other pollutants on their light-transmitting surfaces. The accumulation of dust significantly reduces the light flux of PV modules, thereby significantly reducing their power output capacity. Therefore, cleaning devices are required.

[0003] Most solar panels are cleaned manually, which is slow and ineffective. Furthermore, the individual solar panels inside the photovoltaic module are often spliced ​​together by brackets. In order to improve the conversion rate, the installation angle of the photovoltaic panels varies in different regions. Existing cleaning devices are not flexible enough to clean the photovoltaic panels and cannot be adjusted according to the angle and height of the photovoltaic panels, resulting in poor cleaning effect and failing to meet the usage requirements.

[0004] Therefore, a cleaning device for solar photovoltaic panels is proposed to address the above problems. Utility Model Content

[0010] In a preferred embodiment of the present invention, the support assembly includes a third motor, which is fixedly mounted on one side of the mounting plate, and the output shaft of the third motor is fixedly connected to a third threaded rod.

[0017] Beneficial effects:

[0018] 1. In this utility model, a driving component and an installation mechanism are provided. The installation plate can rotate around the connection between the installation plate and the installation sleeve. At the same time, through the cooperation of various parts of the driving component, the height of the installation sleeve can be adjusted, so that the angle and height of the installation plate can be adjusted.

Detailed Implementation

[0030] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0031] Example 1: As Figure 1-8 The system includes a base 1 and a cleaning plate 2. A column 11 is fixedly installed on the upper end of the base 1. A first threaded rod 12 is rotatably installed on the inner wall of the column 11. An installation mechanism for installing the cleaning plate 2 is provided on the outer wall of the first threaded rod 12. A drive assembly for driving the first threaded rod 12 is provided on the inner wall of the base 1. The installation mechanism includes an installation sleeve 31, which is slidably connected to the column 11. The first threaded rod 12 is threadedly connected to the installation sleeve 31. An installation plate 32 is rotatably connected to the outer wall of the installation sleeve 31. A second motor 36 is fixedly installed on the inner wall of the installation plate 32. A second threaded rod 33 is fixedly connected to the output shaft of the second motor 36. A movable block is threadedly connected to the surface of the second threaded rod 33. 34. A first telescopic rod 35 is fixedly installed on both sides of the inner wall of the movable block 34. The end of the first telescopic rod 35 away from the movable block 34 is fixedly connected to the cleaning plate 2. A support assembly is provided on the outer wall of the mounting plate 32. The support assembly includes a third motor 41, which is fixedly installed on one side of the mounting plate 32. The output shaft of the third motor 41 is fixedly connected to a third threaded rod 42. A mounting base 43 is threadedly connected to the outer wall of the third threaded rod 42. An electric suction cup 44 is fixedly installed at the lower end of the mounting base 43. A guide rod 45 is slidably connected to the inner wall of the mounting base 43. A second telescopic rod 46 is fixedly installed on both sides of the mounting base 43. A walking wheel 47 is provided at the lower end of the second telescopic rod 46.

[0032] The specific practical application scenario of this embodiment is as follows: Both sides of the lower end of the base 1 are equipped with universal wheels with brake pads, making the base 1 easy to move, and the base 1 also serves as a counterweight; a cleaning sponge is fixedly installed at the lower end of the cleaning plate 2; the mounting base 43 is nested within the outer wall of the third threaded rod 42 and the guide rod 45; the third threaded rod 42 is rotatably mounted on one side of the outer wall of the mounting plate 32, and the guide rod 45 is fixedly mounted on the other side of the outer wall of the mounting plate 32; the working principle of the electric suction cup 44 is that a built-in electric motor drives a pump system to extract the air between the suction cup and the object surface, generating negative pressure, allowing the suction cup to firmly adhere to the object surface; when it is necessary to release the adsorbed object, the operation of the electric pump is interrupted by a simple switch operation, and the object can be easily removed; the electric suction cup 44 adopts existing technology; the electric suction cup 44 is very mature in existing technology. Therefore, no further details are provided. A controller is installed on the upper part of the base 1 in a conventional manner to control the entire device. When the third motor 41 is working, it can drive the third threaded rod 42 to rotate, causing the mounting seat 43 on the outer wall of the third threaded rod 42 to move on the outer wall of the mounting plate 32. This allows the mounting seat 43 to press against the upper side of the photovoltaic panel that needs to be cleaned, and the electric suction cup 44 to adhere to the photovoltaic panel. This allows the mounting plate 32 to be stably placed on the upper side of the photovoltaic panel, facilitating the cleaning plate 2 to clean the photovoltaic panel. When the electric suction cup 44 stops working, the second telescopic rod 46 is activated. The traveling wheel 47 at the lower end of the second telescopic rod 46 can press against the upper side of the photovoltaic panel. At this time, the base 1 is pushed to move, and the traveling wheel 47 can move on the upper side of the photovoltaic panel, making it easy to adjust the cleaning position. The inner wall of the mounting plate 32 is provided with a sliding groove, and the movable block 34 is slidably installed on the inner wall of the sliding groove.

[0033] Example 2: As Figure 1-8 The system includes a base 1 and a cleaning plate 2. A column 11 is fixedly installed on the upper end of the base 1. A first threaded rod 12 is rotatably installed on the inner wall of the column 11. An installation mechanism for installing the cleaning plate 2 is provided on the outer wall of the first threaded rod 12. A drive assembly for driving the first threaded rod 12 is provided on the inner wall of the base 1. The drive assembly includes a first motor 51, which is fixedly installed on the inner wall of the base 1. The output shaft of the first motor 51 is fixedly connected to a first rotating shaft 52. A first bevel gear 53 is fixedly installed on the outer wall of the first rotating shaft 52. The first bevel gear 53 is driven by a second bevel gear 54, which is fixedly installed on the outer wall of the first threaded rod 12.

[0034] The specific practical scenario of this embodiment is as follows: the teeth on the outer wall of the first bevel gear 53 continuously mesh with the teeth on the outer wall of the second bevel gear 54, so that when the first bevel gear 53 rotates, it can drive the second bevel gear 54 to rotate, so that the first threaded rod 12 on the inner wall of the second bevel gear 54 can rotate, so that the mounting sleeve 31 on the outer wall of the first threaded rod 12 can move up and down; the inner wall of the mounting sleeve 31 is threadedly connected to the first threaded rod 12, and the mounting sleeve 31 is slidably connected to the column 11.

[0035] Example 3: As Figure 1-8 The system includes a base 1 and a cleaning plate 2. A column 11 is fixedly installed on the upper end of the base 1. A first threaded rod 12 is rotatably installed on the inner wall of the column 11. An installation mechanism for installing the cleaning plate 2 is provided on the outer wall of the first threaded rod 12. A drive assembly for driving the first threaded rod 12 is provided on the inner wall of the base 1. A limit plate 61 is fixedly installed on the upper end of the base 1. A clamping plate 62 is rotatably installed on both sides of the limit plate 61.

[0036] The specific practical scenario of this embodiment is as follows: The inner wall of the clamping plate 62 is threaded with a positioning bolt. When the positioning bolt is tightened, the positioning bolt can penetrate the clamping plate 62 and abut against the side wall of the mounting plate 32. The mounting plate 32 is rotated around the mounting sleeve 31 to a vertical state. At this time, the mounting sleeve 31 can move to the lowest side. The mounting plate 32 is driven by the mounting sleeve 31 to enter between the limiting plate 61 and the column 11. When the mounting plate 32 is in a numerical state, the side of the mounting plate 32 closest to the mounting sleeve 31 rests on the mounting sleeve 31, and the other side of the mounting plate 32 contacts the limiting plate 61. The clamping plate 62 is rotated so that the opposite side of the two clamping plates 62 is in contact with the two sides of the mounting plate 32. The friction between the mounting plate 32 and the clamping plate 62 is large. Tightening the positioning bolt allows the two clamping plates 62 to clamp the mounting plate 32.

[0037] The above structures and principles are all general standard parts or components known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0038] The working principle of this utility model is as follows: Push the base 1 to move the device next to the photovoltaic panel that needs cleaning. Loosen the positioning bolt on the clamping plate 62, rotate the clamping plate 62 away from the mounting plate 32, start the first motor 51 to drive the first rotating shaft 52 to rotate. When the first bevel gear 53 rotates, it drives the second bevel gear 54 to rotate, allowing the first threaded rod 12 on the inner wall of the second bevel gear 54 to rotate. This allows the mounting sleeve 31 on the outer wall of the first threaded rod 12 to move upwards, simultaneously supporting the mounting plate 32 and causing it to rotate slowly. This allows the mounting base 43 and its lower electric suction cup 44 to rest on the photovoltaic panel, making the mounting plate 32 parallel to the photovoltaic panel. Start the third motor 41 to drive the third threaded rod 42 to rotate, allowing the outer part of the third threaded rod 42 to rotate. The mounting base 43 is moved to the upper part of the photovoltaic panel, and the electric suction cup 44 is activated to adhere to the photovoltaic panel. The second motor 36 is activated, which drives the second threaded rod 33 to rotate, causing the movable block 34 to move on the inner wall of the mounting plate 32. At the same time, the first telescopic rod 35 is activated, which moves the cleaning plate 2 downward, so that the cleaning plate 2 is pressed against the surface of the photovoltaic panel. The movable block 34 moves the cleaning plate 2 on the surface of the photovoltaic panel to clean and wipe the photovoltaic panel. When it is necessary to adjust the cleaning position, the electric suction cup 44 stops working and separates from the photovoltaic panel. At the same time, the second telescopic rod 46 is activated, which causes the traveling wheel 47 to roll and connect to the surface of the photovoltaic panel, pushing the base 1 to move. The entire equipment and the cleaning plate 2 can then be moved to the place that needs to be cleaned.
