Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel technology, specifically to an easily adjustable protective decorative panel for the surface of a crystalline silicon photovoltaic panel. Background Technology

[0002] In the field of photovoltaic power generation technology, crystalline silicon photovoltaic panels have become the most widely used solar power generation modules due to their high photoelectric conversion efficiency and stable performance. To improve the lifespan, protective performance, and aesthetics of crystalline silicon photovoltaic panels, protective decorative panels are typically installed on their surface. In existing technologies, the angle between the protective decorative panel and the crystalline silicon photovoltaic panel is often achieved through a fixed connection method, i.e., the protective decorative panel is directly fixed to the photovoltaic panel surface at a preset angle using adhesives, mechanical fasteners, etc.

[0003] This type of fixed-angle protective decorative panel has obvious limitations. In terms of heat dissipation, the fixed-angle structure makes the airflow path between the protective decorative panel and the photovoltaic panel relatively fixed, and it is impossible to optimize air convection according to changes in ambient temperature. In high-temperature environments, it is difficult to effectively reduce the surface temperature of the photovoltaic panel, thus affecting the power generation efficiency of the photovoltaic panel. In low-temperature environments, it is also impossible to reduce heat loss and maintain the operating temperature of the photovoltaic panel by adjusting the angle. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides an easily adjustable protective decorative panel for the surface of crystalline silicon photovoltaic panels, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an easily adjustable protective decorative plate for the surface of a crystalline silicon photovoltaic panel, comprising a mounting shell, a photovoltaic panel body, and a protective plate;

[0006] The photovoltaic panel body is installed on the inner bottom wall of the mounting shell. The protective plate is provided with a rotating shaft on both the left and right sides. The two rotating shafts are respectively rotatably connected to the left and right sides of the inner wall of the mounting shell. An adjustment component is provided on the outer side of the mounting shell and is connected to the rotating shaft for driving the protective plate to rotate on the ZX surface.

[0007] The mounting housing is equipped with a temperature sensor that is electrically connected to the regulating component.

[0008] Baffles are installed on both the left and right sides of the upper surface of the protective plate, and the baffles are in contact with the upper surface of the mounting shell. A horizontal plate is provided on the front side of the protective plate, and the horizontal plate is in contact with the front side of the mounting shell.

[0009] Furthermore, the baffle includes a horizontal portion and a vertical portion;

[0010] The horizontal portion and the vertical portion are integrally formed.

[0011] Furthermore, the horizontal portion is attached to the upper surface of the mounting housing, and the vertical portion is attached to the side surface of the mounting housing.

[0012] Furthermore, the adjustment assembly includes a drive plate that is drivenly connected to the rotating shaft, and an electric push rod is hinged to the side of the mounting housing via a hinge shaft. The output end of the electric push rod is hinged to the drive plate via the hinge shaft.

[0013] Furthermore, the cross-sectional shape of the drive board on the ZX surface is arc-shaped.

[0014] Furthermore, the protective plate is fitted between the left and right sides of the inner wall of the mounting shell.

[0015] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0016] 1. This easily adjustable protective decorative panel on the surface of the crystalline silicon photovoltaic panel can automatically adjust its angle according to the ambient temperature through the linkage of a temperature sensor and an adjustment component. At high temperatures, the ventilation gap between the panel and the main body of the photovoltaic panel is increased to enhance air convection and heat dissipation, while at low temperatures the gap is reduced to decrease heat loss. This solves the problem that traditional fixed-angle protective panels cannot dynamically optimize thermal management, enabling the main body of the photovoltaic panel to maintain a better operating temperature in different seasons and improving power generation efficiency.

[0017] 2. This easily adjustable protective decorative panel for the surface of the crystalline silicon photovoltaic panel has a three-sided sealing structure formed by the horizontal and vertical parts of the baffle and the horizontal plate. This ensures that the protective panel fits tightly against the mounting shell when closed, effectively preventing dust, rainwater, insects, etc. from entering the interior of the mounting shell, reducing the risk of surface contamination and mechanical damage to the photovoltaic panel, and extending the service life of the equipment.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-2 In this embodiment, an easily adjustable protective decorative plate for the surface of a crystalline silicon photovoltaic panel is used to adjust the angle between the photovoltaic panel body 2 and the protective plate 3.

[0023] Specifically, it includes a mounting shell 1, a photovoltaic panel body 2, and a protective plate 3; the photovoltaic panel body 2 is installed on the inner bottom wall of the mounting shell 1, and the protective plate 3 is provided with rotating shafts 7 on both the left and right sides. The two rotating shafts 7 are rotatably connected to the left and right sides of the inner wall of the mounting shell 1, respectively. An adjustment component 4 is provided on the outer side of the mounting shell 1 and is connected to the rotating shafts 7 for driving the protective plate 3 to rotate on the ZX surface.

[0024] The interior of the mounting housing 1 contains a temperature sensor 8 that is electrically connected to the regulating component 4.

[0025] In actual setup, temperature sensor 8 is installed inside mounting housing 1 to monitor the ambient temperature or surface temperature of photovoltaic panel body 2 in real time, and converts the temperature signal into an electrical signal and transmits it to the control system of adjustment component 4. When temperature sensor 8 detects that the temperature exceeds the preset threshold, the control system sends a command to adjustment component 4 to drive protective plate 3 to flip upward, increasing the angle between protective plate 3 and photovoltaic panel body 2 to form an air circulation channel that runs vertically through the photovoltaic panel, thus accelerating heat convection and heat dissipation.

[0026] Furthermore, baffles 5 are installed on both the left and right sides of the upper surface of the protective plate 3. The baffles 5 are in contact with the upper surface of the mounting shell 1. A horizontal plate 6 is provided on the front side of the protective plate 3. The horizontal plate 6 is in contact with the front side of the mounting shell 1.

[0027] In detail, the baffle 5 includes a horizontal part 501 and a vertical part 502; the horizontal part 501 and the vertical part 502 are integrally formed, the horizontal part 501 is attached to the upper surface of the mounting shell 1, and the vertical part 502 is attached to the side of the mounting shell 1.

[0028] In actual installation, when the protective plate 3 is closed, the baffle 5 and the mounting shell 1 form a tight "L"-shaped sealing structure. The horizontal part 501 covers the top gap of the mounting shell 1, and the vertical part 502 fits against the side, effectively preventing dust, rainwater and other external debris from entering the interior of the mounting shell 1, thus enhancing the sealing performance and protective effect of the protective plate 3. At the same time, the integral molding design of the baffle 5 and the protective plate 3 improves the overall rigidity and avoids loosening of the connection due to vibration and other factors during long-term use.

[0029] In addition, the horizontal plate 6 is fixed to the front side of the protective plate 3 and fits against the front side of the mounting shell 1. Together with the baffle 5, it forms a three-sided sealing structure of the protective plate 3, which further improves the sealing performance of the protective plate 3 when it is closed, ensuring that the photovoltaic panel body 2 is completely wrapped. Especially in harsh environments such as wind, sand, rain and snow, it can significantly reduce the risk of damage to the photovoltaic panel from external factors.

[0030] In detail, in order to facilitate the up-and-down flipping of the protective plate 3, the adjustment component 4 in this embodiment includes a drive plate 401 that is connected to the rotating shaft 7, and an electric push rod 402 is hinged to the side of the mounting shell 1 via a hinge shaft. The output end of the electric push rod 402 is hinged to the drive plate 401 via a hinge shaft.

[0031] In detail, the drive plate 401 has an arc-shaped cross-section on the ZX surface, and the protective plate 3 is attached between the left and right sides of the inner wall of the mounting shell 1.

[0032] In actual use, when the temperature sensor 8 detects that the ambient temperature exceeds the preset threshold, it sends a signal to the electric push rod 402. The electric push rod 402 starts and extends, pushing the drive plate 401 to rotate counterclockwise around the rotating shaft 7, causing the protective plate 3 to flip upward and increase the angle between it and the photovoltaic panel body 2. At this time, an air circulation channel is formed between the protective plate 3 and the photovoltaic panel body 2. Air can enter from the gap between the bottom mounting shell 1 and the bottom of the protective plate 3, flow through the surface of the photovoltaic panel body 2 and then be discharged from the top. The principle of heat convection is used to accelerate heat dissipation, reduce the surface temperature of the photovoltaic panel body 2 and avoid the decrease in power generation efficiency caused by high temperature.

[0033] In addition, when the temperature sensor 8 detects that the ambient temperature is lower than the preset threshold, the electric push rod 402 retracts, pulling the drive plate 401 to rotate clockwise around the rotating shaft 7, causing the protective plate 3 to flip downward and close to the photovoltaic panel body 2. At this time, the air layer between the protective plate 3 and the photovoltaic panel body 2 becomes thinner, reducing heat loss through air convection, which helps maintain the working temperature of the photovoltaic panel body 2 and improves the power generation stability in low-temperature environments.

[0034] In actual setup, the telescopic movement of the electric push rod 402 is transmitted to the drive plate 401 through the hinge shaft. Since the cross-section of the drive plate 401 is arc-shaped, the movement trajectory of its connection point with the electric push rod 402 is an arc, thus converting the linear motion into the rotational motion of the rotating shaft 7. This transmission method can effectively control the rotation angle of the protective plate 3 by adjusting the stroke of the electric push rod 402, thereby meeting the heat dissipation or heat preservation requirements under different ambient temperatures.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
