Description

Technical Field

[0001] This utility model relates to the field of solar photovoltaic panel cleaning technology, and in particular to a solar photovoltaic panel and its automatic cleaning equipment. Background Technology

[0002] Solar energy, as a clean, inexhaustible, and renewable energy source, is finding increasingly widespread applications. Solar photovoltaic (PV) panels are key components in solar power generation systems, and their efficiency directly impacts the overall system's power generation efficiency. However, during long-term use, exposed to the outdoor environment, PV panels easily accumulate dust, bird droppings, grime, and other contaminants on their surfaces. These contaminants significantly reduce the power generation efficiency of the PV panels.

[0003] Therefore, regular cleaning of solar photovoltaic panels is essential. Traditional cleaning methods rely on manual labor, which is inefficient and insufficient to meet the cleaning needs of existing large-scale photovoltaic power plants, especially in complex terrains such as mountains, deserts, and wetlands, where the difficulty and cost of cleaning increase exponentially. In remote areas, human resources are scarce, manual cleaning is costly, and the frequency of cleaning is insufficient to maintain the cleanliness of photovoltaic panels in the long term. Manual cleaning also carries high safety risks, with harsh working environments that can easily lead to accidents. Furthermore, manual cleaning cannot guarantee uniform cleanliness of the photovoltaic panel surface; differences in cleaning results among different workers can lead to inconsistent cleanliness levels, affecting overall power generation efficiency.

[0004] Of course, there are also non-manual cleaning methods using machinery. Cleaning equipment and robotics technologies are constantly developing, and specialized cleaning robots for solar photovoltaic panels can improve cleaning efficiency and reduce labor costs.

[0005] Most existing cleaning robots operate on the ground in the form of vehicles. For example, existing technology (CN106040625 A) proposes a solar photovoltaic panel cleaning device with an adaptively adjustable cleaning brush, consisting of four parts: a vehicle body, an automatic cleaning brush adjustment device, an adaptive cleaning brush adjustment device, and the cleaning brush body. The installation of ground-mounted photovoltaic power stations involves significant lateral elevation differences and varying installation spacing, placing very high demands on the cleaning robot's traversing capabilities. This limits its application in complex terrain.

[0006] Furthermore, some cleaning robots may require specific weather or environmental conditions to function properly, such as water-clamp cleaning equipment that needs to operate in rainy weather or with water present. This limits their application in different environments. While large cleaning equipment can improve cleaning efficiency, it is expensive and requires a large operating space, making it unsuitable for large photovoltaic power plants. Some large robots specifically designed for cleaning solar photovoltaic panels have high equipment and maintenance costs, and many blind spots in cleaning, which actually increases the cost of photovoltaic power generation.

[0007] To overcome the shortcomings of mechanical, non-manual cleaning methods and optimize their use, an improved automated cleaning device for solar photovoltaic panels is still needed. Utility Model Content

[0048] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0049] As mentioned in the background section, most existing cleaning robots operate on the ground in the form of vehicles. However, ground-mounted photovoltaic power stations have significant vertical differences and varying installation spacing, placing high demands on the cleaning robots' traversing capabilities. This limits their application in complex terrains. Some cleaning robots may only function properly under specific weather or environmental conditions, such as water-guided clamp cleaning equipment that requires rain or water. This restricts their application in different environments. While large-scale cleaning equipment can improve cleaning efficiency, it is expensive and requires significant operating space, making it unsuitable for large-scale photovoltaic power stations. Some large robots specifically designed for cleaning solar photovoltaic panels are also expensive to operate and maintain, have many blind spots, and their use actually increases the cost of photovoltaic power generation. Based on existing cleaning robot technology, installing the cleaning device independently on the photovoltaic panel is believed to solve one or more of the problems in the existing technology.

[0050] To address the aforementioned technical problems, this utility model provides an automatic cleaning device 1 for solar photovoltaic panels 2, such as... Figure 1-10 As shown. Figure 1 As shown, the automatic cleaning device 1 is installed on the solar photovoltaic panel 2, which is generally installed on the inclined photovoltaic panel support 3. Figure 2 A plurality of consecutively and neatly installed solar photovoltaic panels 2 are shown, with an automatic cleaning device 1 installed on one of the solar photovoltaic panels 2. The automatic cleaning device 1 can move left and right along the upper and lower edges of the plurality of consecutively installed solar photovoltaic panels 2, thereby cleaning the entire solar photovoltaic panel 2.

[0051] like Figure 3-4 As shown, the automatic cleaning device 1 includes:

[0052] The housing 22 includes an outer top plate and side plates extending vertically from each side of the outer top plate. The housing 22 also includes a control system 6 for controlling the start / stop, parameter setting, and operation indication of the automatic cleaning equipment 1, such as... Figure 2 As shown. The control system 6 and the housing 22 are the control installation locations for the entire automatic cleaning equipment 1. They are responsible for controlling the start and stop of the automatic cleaning equipment 1, as well as parameter settings and operation instructions. The housing 22 protects the key parts of the equipment and enhances its appearance. The side panels of the housing 22 can also shield the dirt generated during the cleaning process from splashing into other areas.

[0053] The equipment includes a solar photovoltaic panel 4, which is installed on the outer side of the top panel and parallel to the solar photovoltaic panel 2. Since the automatic cleaning equipment 1 is installed on the solar photovoltaic panel 2, it will inevitably block part of the solar photovoltaic panel 2. Installing a solar photovoltaic panel 4 on the outer side of the top panel of the automatic cleaning equipment 1 can compensate for the energy loss of the area of ​​the solar photovoltaic panel 2 covered by the automatic cleaning equipment 1 during operation, and can also reduce the energy consumption of the automatic cleaning equipment 1. The solar photovoltaic panel 4 is equivalent to a supplementary energy device.

[0054] A left-right moving mechanism 7 is mounted on the outer casing 22 and extends out of the side plate. The left-right moving mechanism 7 slides in contact with the upper and lower edges of the solar photovoltaic panel 2, allowing the outer casing 22 to move along the length of the upper or lower edge of the solar photovoltaic panel 2. The main function of the left-right moving mechanism 7 is to install the automatic cleaning device 1 on the solar photovoltaic panel 2 and to rotate the automatic cleaning device 1 to move left and right relative to the solar photovoltaic panel 2.

[0055] The cleaning machine head assembly 5 is mounted on the outer casing 22 and located between the outer top plate of the outer casing 22 and the solar photovoltaic panel 2, for cleaning the solar photovoltaic panel 2. The cleaning machine head assembly 5 is the core of the entire equipment and is mainly responsible for cleaning the photovoltaic solar panel.

[0056] A vertical moving mechanism 8 is mounted on the housing 22 and connected to the cleaning machine head assembly 5, allowing the cleaning machine head assembly 5 to reciprocate between the upper and lower edges of the solar photovoltaic panel 2. The vertical moving mechanism 8 drives the cleaning assembly to move up and down.

[0057] For the directions "left" and "right" and the positions of "top edge" and "bottom edge", please refer to [link / reference]. Figure 2 .

[0058] The aforementioned automatic cleaning device 1 is installed on the solar photovoltaic panel 2, requiring no specific ground conditions and unrestricted by terrain or area. This automatic cleaning device 1 possesses autonomous movement capabilities, enabling it to perform complete cleaning in both vertical and horizontal dimensions on the photovoltaic panel, meeting the cleaning needs of large-scale photovoltaic power plants. The automatic cleaning device 1 adopts a modular design, is small in size, low in cost, and has a simple structure. Furthermore, its integrated photovoltaic panel reduces energy consumption at the power plant, resulting in greater cost savings.

[0059] Specifically, such as Figure 6-7 As shown, the left-right moving mechanism 7 includes a left-right driven wheel 18, a left-right driving wheel 19, and a left-right moving motor 20; the left-right driving wheel 19 is mounted on the outer casing 22 at the corresponding position on the upper edge of the solar photovoltaic panel 2 (i.e., near the upper side plate 23) and extends out of the upper side plate 23; the left-right driving wheel 19 is connected to the left-right moving motor 20, and the left-right driving wheel 19 slides in contact with the upper edge of the solar photovoltaic panel 2 (e.g., ...). Figure 1 (As shown); the left and right motion motor 20 drives the left and right motion drive wheel 19 to move along the length direction of the upper edge of the solar photovoltaic panel 2.

[0060] The left-right driven wheel 18 is mounted on the lower side plate 24 of the outer casing 22 at the corresponding position of the lower edge of the solar photovoltaic panel 2 and extends out of the lower side plate 24. The left-right driven wheel 18 slides in contact with the lower edge of the solar photovoltaic panel 2; the left-right driven wheel 18 moves synchronously along the lower edge of the solar photovoltaic panel 2 as the left-right driving wheel 19 moves (e.g., Figure 1 (As shown).

[0061] The left and right moving component is key to mounting the entire automatic cleaning device 1 on the tilted photovoltaic solar panel. The left and right moving drive wheel 19 is placed on the upper edge of the photovoltaic solar panel, and the left and right moving driven wheel 18 is placed on the lower edge of the photovoltaic solar panel. Driven by the left and right moving motor 20, the entire device can move left and right on the continuous solar photovoltaic panel 2.

[0062] Specifically, such as Figure 5-7 As shown, the up-and-down moving mechanism 8 includes an up-and-down running synchronous belt 15, an up-and-down moving motor 14, and an up-and-down moving driven wheel 17; the up-and-down moving motor 14 is mounted on the housing 22 at the position corresponding to the upper edge of the solar photovoltaic panel 2, and the up-and-down moving driven wheel 17 is mounted on the housing 22 at the position corresponding to the lower edge of the solar photovoltaic panel 2.

[0063] One end of the up-and-down synchronous belt 15 is fixed to one side of the cleaning machine head assembly 5 by the synchronous belt fixing block 16. The other end of the up-and-down synchronous belt 15 passes through the fixing point of the up-and-down motion motor 14 and the up-and-down motion driven wheel 17 in sequence, and is then fixed to the other side of the cleaning machine head assembly 5 by the synchronous belt fixing block 16. The up-and-down motion motor 14 drives the up-and-down synchronous belt 15 to pull the cleaning machine head assembly 5 back and forth between the upper edge and the lower edge of the solar photovoltaic panel 2.

[0064] In the up-and-down moving assembly, the up-and-down running synchronous belt 15 is fixed to the cleaning machine head assembly 5 by the synchronous belt fixing block 16, and the other end is also fixed around the up-and-down moving driven wheel 17. The up-and-down moving motor 14 rotates to drive the synchronous belt, thereby pulling the cleaning machine head assembly 5 to move up and down.

[0065] The up-and-down moving mechanism 8 also includes a tank chain 21 for cable water pipes (such as...). Figure 7 As shown in the figure, these are mechanical equipment accessories used to protect and support pipelines such as cables and water pipes.

[0066] like Figure 8-10 The cleaning machine head assembly 5 shown includes:

[0067] Brush cover 11; brush cover 11 includes a top plate and four side plates extending from the top plate;

[0068] A rubber scraper 10 is disposed inside the brush cover 11; wherein the lowest end of the rubber scraper 10 is slightly lower than the lowest end of the side plate of the brush cover 11.

[0069] The brush roller 9 is disposed in the space between the side wall of the brush cover 11 and the rubber scraper 10; the brush roller 9 is arranged parallel to the rubber scraper 10; wherein, the lowermost end of the brush roller 9 is slightly lower than the lowermost end of the side plate of the brush cover 11.

[0070] Roller brush motor 12 drives brush roller 9 to rotate;

[0071] The spray head 13 is used to supply water to the brush roller 9, such as Figure 8 As shown, the spray head 13 is a water pipe with a length similar to that of the brush roller 9, and multiple spray holes are opened on the water pipe. The spray head 13 is set between the top plate of the brush roller 9 and the brush cover 11 to supply water to the brush roller 9 for cleaning.

[0072] When the cleaning machine head assembly 5 is placed on the solar photovoltaic panel 2, the rubber scraper 10 of the cleaning machine head assembly 5 is arranged parallel to the upper edge of the solar photovoltaic panel 2, and the rubber scraper 10 is arranged parallel to the side of the brush cover 11 where the upper and lower running synchronous belt 15 and the fixing point of the cleaning machine head assembly 5 are located.

[0073] The brush roller 9 is used to scrub the glass panel of the solar photovoltaic panel 2 during the cleaning process. Driven by the roller brush motor 12, the roller rotates. Water can be added via the spray nozzle 13 during the scrubbing process, resulting in a more thorough cleaning of the glass panel. The rubber scraper 10 separates the two sets of rollers, allowing for different operating modes. By controlling water addition and the rotation direction of the two sets of rollers, a greater cleaning effect can be achieved. During the cleaning process, the rubber scraper 10 effectively adheres to the glass surface, carrying the cleaned dirt to one end of the solar photovoltaic panel 2. For example, if the cleaning machine head assembly 5 cleans from the top edge to the bottom edge of the solar photovoltaic panel 2, the rubber scraper 10 can scrape the cleaned dirt from the top edge to the bottom edge. The brush cover 11 effectively prevents dust and water from splashing and spreading during the operation of the roller brush.

[0074] Working principle of automatic cleaning device 1:

[0075] Automatic cleaning equipment 1 is suitable for large-scale photovoltaic solar power plants. Because large-scale photovoltaic solar power plants have a large number of solar photovoltaic panels 2 and multiple solar photovoltaic panels 2 are installed together to form a large-scale photovoltaic array, an automatic cleaning equipment 1 is placed in each continuous array unit to perform long-term, stable, and timed cleaning and maintenance of the solar photovoltaic panels 2 in this unit.

[0076] First, install the automatic cleaning device 1 on one end of the continuous solar photovoltaic panel 2, and set the required operating mode and parameters on the control panel, such as whether to perform water spray cleaning, the rotation direction of each roller brush, the rotation speed of the roller brush, the operating speed of the upper and lower operating mechanism during cleaning, etc.

[0077] Secondly, after the automatic cleaning device 1 is started, the cleaning components operate according to the parameters set for different usage environments. The up-and-down movement mechanism drives the cleaning components to clean the solar photovoltaic panels 2. Once the area covered by the up-and-down movement is clean, the left-and-right movement mechanism moves the automatic cleaning device 1 one position and cleans it again. This cycle continues until it moves from one end of the solar photovoltaic panel 2 array unit to the other, thus completing one cycle. This ensures that the solar photovoltaic panels 2 remain clean and operate stably and effectively over a long period. In some preferred embodiments, multiple automatic cleaning devices can be connected to a network for remote monitoring, remote start / stop, and parameter adjustment, depending on the usage environment.

[0078] The embodiments of this disclosure have now been described in detail. To avoid obscuring the concept of this disclosure, some details known in the art have not been described.
