Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel technology, specifically to a photovoltaic panel for photovoltaic power generation that is easy to maintain. Background Technology

[0002] Photovoltaic panels are one of the most important components in a photovoltaic power generation system. Their function is to convert solar energy into electrical energy. The structure of a photovoltaic panel typically consists of several parts, including a glass cover, EVA adhesive, silicon wafers, a backsheet, and an aluminum frame. The glass cover protects the photovoltaic panel from the influence of the external environment while allowing light to pass through and illuminate the silicon wafers. EVA adhesive is a special type of glue that firmly bonds the silicon wafers and the glass cover together, while also preventing moisture and dust from penetrating the interior of the photovoltaic panel. The silicon wafer is the core component of a photovoltaic panel, converting light energy into electrical energy. The backsheet and aluminum frame support and fix the entire structure of the photovoltaic panel. Currently, in outdoor environments, photovoltaic panels often accumulate various contaminants on their surface. These contaminants affect the panel's light absorption capacity and power generation efficiency, thus requiring regular cleaning and maintenance. During this process, workers typically use clean water and a soft brush to gently clean the surface of the photovoltaic panel. For smaller contaminants or hard-to-clean areas, a soft cloth or sponge can be used for gentle wiping. However, due to the large surface area of ​​the photovoltaic panel, workers often find it difficult to detect and clean all the contaminants in a timely manner, meaning that the accumulation of contaminants in certain areas is overlooked, resulting in poor cleaning results.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0018] Please see Figure 1-5 This utility model provides an embodiment of a photovoltaic panel for easy maintenance, comprising a solar photovoltaic panel 1 and a base plate 2 with the bottom edge of the solar photovoltaic panel 1 being installed at the same length. A right-angle arm 3 is installed on the back of the base plate 2, and a vertical plate 4 is fixed on the surface of the right-angle arm 3. A support 5 is fixed at one end of the surface of the vertical plate 4, and a three-way valve 6 is installed on the outer wall of the support 5 away from the right-angle arm 3. Diverter pipes 7 are installed at the two outlet ends of the three-way valve 6. Vertical multi-point spray structure 1 8 and vertical multi-point spray structure 2 9 are respectively installed at the top of the two diverter pipes 7. When an external water pipe is connected to the inlet of the three-way valve 6, the external cleaning fluid can be introduced into the vertical multi-point spray structure 1 8 and vertical multi-point spray structure 2 9 through the two diverter pipes 7 respectively.

[0019] A sponge strip 11 of the same length as itself is installed on the back of the upright plate 4, and the back of the sponge strip 11 is in contact with the surface of the solar photovoltaic panel 1.

[0020] The vertical panel 4 is made of aluminum alloy. Aluminum alloy has a light density and high strength, so the vertical panel 4 is lightweight but has sufficient structural strength, which can reduce the weight load of the vertical panel 4 on the solar photovoltaic panel 1.

[0021] Two symmetrical dovetail guide rails 201 are fixed on the back of the base plate 2. A sliding sleeve 202 that slides with the dovetail guide rails 201 is installed on the inner wall of one side of the right-angle arm 3. When the upright plate 4, right-angle arm 3, three-way valve 6 and other components slide horizontally, the right-angle arm 3 will drive the sliding sleeve 202 to slide in the extension direction of the base plate 2 and the dovetail guide rails 201. The sliding stability of the vertical multi-point spray structure, sponge strip 11 and other components is improved by the dovetail guide rails 201 and the sliding sleeve 202.

[0022] Vertical multi-point spray structure 1 (8) and vertical multi-point spray structure 2 (9) have the same structure. Vertical multi-point spray structure 1 (8) includes a riser 801 installed at the outlet of the diversion pipe 7, and several diversion straight pipes 802 installed at equal intervals on the back of the riser 801. A right-angle elbow 10 is installed at the top of the riser 801. When the three-way valve 6 is connected to the cleaning fluid pump end, the cleaning fluid enters vertical multi-point spray structure 1 (8) and vertical multi-point spray structure 2 (9) through the diversion pipe 7. That is, the cleaning fluid first enters the riser 801 and is led out through several diversion straight pipes 802. Vertical multi-point spray structure 1 (8) and vertical multi-point spray structure 2 (9) can spray the cleaning fluid onto the dirt on the surface of the photovoltaic panel without wasting it elsewhere. Moreover, the design of the sponge strip 11 can effectively absorb and recover the sprayed cleaning fluid, reducing the consumption of cleaning fluid and lowering the cleaning cost.

[0023] There are two sponge strips 11, and the two sponge strips 11 are symmetrical about the vertical center reference plane of the upright plate 4. By setting two sponge strips 11, the simultaneous wiping of the two sponge strips 11 can cover a wider area, effectively remove dirt, reduce dirt residue on the surface of the photovoltaic panel, and improve cleaning efficiency.

[0024] In this embodiment, the operator first connects the external water pipe to the inlet of the three-way valve 6. The external cleaning fluid can then be introduced into the vertical multi-point spray structure 1 (8) and the vertical multi-point spray structure 2 (9) through two branch pipes 7. The cleaning fluid is then sprayed onto the glass surface of the solar photovoltaic panel 1 through the vertical multi-point spray structure 1 (8) and the vertical multi-point spray structure 2 (9). The operator can manually raise the plate 4, causing the branch pipes 7, the vertical multi-point spray structure 1 (8), the vertical multi-point spray structure 2 (9), and the right-angle arm 3 to slide in the extension direction of the base plate 2. This ensures that the cleaning fluid sprayed from the vertical multi-point spray structure 1 (8) and the vertical multi-point spray structure 2 (9) evenly covers the panel surface. During this process, because the sponge strip 11 is located within the vertical multi-point spray structure... Between the vertical multi-point spray structure 18 and the vertical multi-point spray structure 29, and in contact with the glass surface of the photovoltaic panel, the sponge strip 11 simultaneously wipes the panel surface with cleaning fluid. Since the height of the vertical multi-point spray structure 18, the vertical multi-point spray structure 29, and the sponge strip 11 is approximately the same as the height of the solar photovoltaic panel 1, the staff only needs to slide the vertical plate 4 to complete the spraying of cleaning fluid and the wiping of the panel surface. The two symmetrical vertical multi-point spray structures in this photovoltaic panel can evenly spray cleaning fluid on the surface of the photovoltaic panel to wash away dirt, while the sponge strip 11 can wipe while spraying water, ensuring that the surface of the photovoltaic panel is thoroughly clean. Compared with traditional cleaning methods, this design has a larger wiping range and can more thoroughly remove dirt, thereby maintaining the high-efficiency power generation state of the photovoltaic panel.

[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
