Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic solar panels, and specifically relates to a protection device for photovoltaic solar panels. Background Art

[0002] A photovoltaic solar panel is a device that converts solar energy into electrical energy using the photovoltaic effect. Its working principle is that when sunlight shines on the surface of a solar cell, photons hit the semiconductor material, exciting electrons, thereby generating an electric current within the material. This electric current can be used for power supply or storage after passing through the circuit connecting the cells. If the photovoltaic solar panel is not properly protected during operation, its surface will be impacted, affecting its operation.

[0003] A Chinese patent with the application number 201721091504.4 discloses a portable adjustable photovoltaic bracket, including a photovoltaic panel, a protective cover, a vacuum cleaner, an electric hydraulic cylinder, a battery box, and a photovoltaic power conversion box. An electric hydraulic cylinder is provided at the top of the second base, and a first base is installed at the top of the electric hydraulic cylinder. The output shaft of the electric hydraulic cylinder is connected to the first base. A limiting plate is installed at one end of the top of the first base, and a photovoltaic panel is installed on the top of the limiting plate. The photovoltaic panel is connected to the limiting plate through a first bracket. The portable adjustable photovoltaic bracket of the utility model can adjust the height of the photovoltaic panel according to the lighting environment by setting the electric hydraulic cylinder, enabling the photovoltaic panel to generate electricity more efficiently. By setting the vacuum cleaner, the dust on the photovoltaic panel can be removed, avoiding the influence on the power generation effect of the photovoltaic panel due to dust adhering to the surface of the photovoltaic panel. By setting the protective cover, the photovoltaic panel can be effectively protected from damage.

However, with continuous use, the surface of the protective cover will continuously come into contact with external sand and stones, inevitably resulting in scratches on the surface of the protective cover. When the degree of scratching on the surface of the protective cover is relatively high, it will affect the entry of sunlight, thereby reducing the light absorption efficiency of the internal photovoltaic panel, and thus affecting the working efficiency of the photovoltaic panel to a certain extent.

[0005] Therefore, a protection device for photovoltaic solar panels is proposed to address the above problems. Summary of the Utility Model

[0024] The following gives specific embodiments.

[0025] Please refer to Figure 1 - Figure 5, the utility model provides a protection device for a photovoltaic solar panel, including a base 1; a semi-open protection box 2 is fixedly connected to the top of the base 1; the semi-open protection box 2 is composed of a detachable rear plate and four columns; a rotating frame 3 is fixedly connected to the bottom of the inner wall of the semi-open protection box 2; a photovoltaic panel 4 is rotatably connected to the surface of the rotating frame 3; an upper glass transparent plate 5 is clamped to the top of the semi-open protection box 2; a front glass transparent plate 6 is clamped to one side of the semi-open protection box 2; dust-proof and breathable plates 7 are fixedly connected to both sides of the semi-open protection box 2; during operation, the base 1 supports the semi-open protection box 2, and the semi-open protection box 2 can be disassembled.

The upper glass transparent plate 5 and the front glass transparent plate 6 are clamped. When it is necessary to replace the upper glass transparent plate 5 and the front glass transparent plate 6, the rear plate and the four columns in the semi-open protection box 2 can be disassembled, so as to replace the clamped upper glass transparent plate 5 and the front glass transparent plate 6, providing real-time protection for the photovoltaic panel 4, without affecting the normal operation of the photovoltaic panel 4. While ensuring the protection effect, the working efficiency of the photovoltaic panel is also improved, and the adaptability of use is enhanced.

[0026] Further, as Figure 2 , Figure 3 and Figure 5As shown, a card slot 8 adapted to the upper glass transparent plate 5 and the front glass transparent plate 6 is provided on the surface of the semi-open protection box 2; the upper glass transparent plate 5 and the front glass transparent plate 6 are made of borosilicate glass; the bottom of the inner wall of the semi-open protection box 2 is fixedly connected with an auxiliary rotating frame 9; the bottom of the inner wall of the semi-open protection box 2 is rotatably connected with an electric telescopic rod 10 through the auxiliary rotating frame 9; one end of the electric telescopic rod 10 is movably connected with the bottom of the photovoltaic panel 4; the number of the dust-proof breathable plates 7 is set to two, and the two dust-proof breathable plates 7 are symmetrically arranged on both sides of the semi-open protection box 2; a shield 11 is fixedly connected to both sides of the semi-open protection box 2. During operation, a card slot 8 adapted to the upper glass transparent plate 5 and the front glass transparent plate 6 is provided on the semi-open protection box 2, and the upper glass transparent plate 5 and the front glass transparent plate 6 are conveniently installed by using the card slot 8. At the same time, the upper glass transparent plate 5 and the front glass transparent plate 6 are made of borosilicate glass, and their high hardness, high heat resistance and light transmission characteristics are utilized to effectively prevent external objects from hitting and enable light to irradiate on the surface of the photovoltaic panel 4 so that it can work normally. An auxiliary rotating frame 9 is provided in the semi-open protection box 2 to support the electric telescopic rod 10. When the electric telescopic rod 10 works, it pushes up the photovoltaic panel 4. The electric telescopic rod 10 is movably connected with the photovoltaic panel 4 and rotates on the auxiliary rotating frame 9 at the same time to avoid movement interference during operation, so as to normally adjust the angle of the photovoltaic panel 4. The dust-proof breathable plates 7 prevent external dust from entering the semi-open protection box 2 and finally adhering to the surface of the photovoltaic panel 4, affecting its working efficiency. The shield 11 is used to prevent rainwater from entering the semi-open protection box 2 through the dust-proof breathable plates 7, so that the inside of the semi-open protection box 2 is in a humid state, realizing the functions of waterproofing and moisture-proofing.

[0027] Further, as Figure 4 shown, a straight oral cavity 12 is provided at the bottom of the inner wall of the semi-open protection box 2; a micro motor 13 is fixedly connected to the bottom of the inner wall of the straight oral cavity 12; the number of the straight oral cavities 12 and the micro motors 13 is set to four, and the four straight oral cavities 12 and the micro motors 13 are symmetrically arranged in pairs on both sides of the auxiliary rotating frame 9; the output shafts of the four micro motors 13 are fixedly connected with rotating fan blades 14 through couplings. During operation, a straight oral cavity 12 is provided at the bottom of the inner wall of the semi-open protection box 2, and four straight oral cavities 12 are provided at the same time for installing the micro motors 13. The micro motor 13 is fixedly installed with the rotating fan blade 14. When the micro motor 13 works, it drives the rotating fan blade 14 to start rotating, blowing air into the semi-open protection box 2 to accelerate the internal air circulation, achieving the heat dissipation effect, avoiding the influence of internal high temperature on the operation of the photovoltaic panel 4, and at the same time making the internal air circulation of the semi-open protection box 2 larger than that of the outside world, making it more difficult for external dust to enter the semi-open protection box 2 and improving the dust-proof adaptability.

[0028] Working principle: Since the above patent provides a portable adjustable photovoltaic bracket, although it can effectively protect the photovoltaic panel from damage, with continuous use, the surface of the protective cover will constantly come into contact with sand and stones in the outside world, which will inevitably cause scratches on the surface of the protective cover. When the degree of scratching on the surface of the protective cover is relatively high, it will affect the entry of sunlight, and then lead to the light absorption efficiency of the internal photovoltaic panel, thus affecting the working efficiency of the photovoltaic panel to a certain extent. During operation, the base 1 supports the semi-open protection box 2, and the semi-open protection box 2 can be disassembled. A rotating frame 3 is fixed inside the semi-open protection box 2 to support the photovoltaic panel 4 and enable it to be adjusted within a certain angle. The upper glass transparent plate 5 and the front glass transparent plate 6 are snap-connected. When it is necessary to replace the upper glass transparent plate 5 and the front glass transparent plate 6, the rear plate and the four columns in the semi-open protection box 2 can be disassembled, so as to replace the snap-connected upper glass transparent plate 5 and the front glass transparent plate 6, providing real-time protection for the photovoltaic panel 4 while not affecting the normal operation of the photovoltaic panel 4. While ensuring the protection effect, it also improves the working efficiency of the photovoltaic panel and enhances the adaptability of use. Slots 8 adapted to the upper glass transparent plate 5 and the front glass transparent plate 6 are opened in the semi-open protection box 2, which facilitates the installation of the upper glass transparent plate 5 and the front glass transparent plate 6. At the same time, the upper glass transparent plate 5 and the front glass transparent plate 6 are made of borosilicate glass, which utilizes its high hardness, high heat resistance and light-transmitting characteristics to effectively prevent external objects from hitting and enable light to shine on the surface of the photovoltaic panel 4, allowing it to work normally. An auxiliary rotating frame 9 is arranged inside the semi-open protection box 2 to support the electric telescopic rod 10. When the electric telescopic rod 10 works, it pushes up the photovoltaic panel 4. The electric telescopic rod 10 is movably connected to the photovoltaic panel 4 and rotates on the auxiliary rotating frame 9 at the same time to avoid movement interference during operation, so as to normally adjust the angle of the photovoltaic panel 4. The dust-proof breathable plate 7 prevents external dust from entering the inside of the semi-open protection box 2 and finally adhering to the surface of the photovoltaic panel 4, affecting its working efficiency. The baffle 11 is used to prevent rainwater from entering the inside of the semi-open protection box 2 from the dust-proof breathable plate 7, so that the inside of the semi-open protection box 2 is in a humid state, realizing the function of waterproof and moisture-proof. Straight cavities 12 are opened at the bottom of the inner wall of the semi-open protection box 2, and four straight cavities 12 are provided at the same time for installing the micro motors 13. The micro motors 13 are fixedly installed with rotating fan blades 14. When the micro motors 13 work, they drive the rotating fan blades 14 to start rotating, blowing air inside the semi-open protection box 2 to accelerate the internal air circulation, achieving the heat dissipation effect, avoiding the influence of internal high temperature on the operation of the photovoltaic panel 4, and at the same time making the air circulation inside the semi-open protection box 2 larger than that of the outside world, making it more difficult for external dust to enter the semi-open protection box 2, improving the dust-proof adaptability. By setting the semi-open protection box 2, and the semi-open protection box 2 is composed of a rear plate and four columns, the rear plate and the four columns can be disassembled. When the degree of scratching on the surfaces of the upper glass transparent plate 5 and the front glass transparent plate 6 is relatively high,The upper glass transparent plate 5 and the front glass transparent plate 6 can be disassembled and replaced without replacing the entire semi-open protection box 2, which reduces the maintenance cost. The photovoltaic panel 4 is arranged inside the semi-open protection box 2, and the semi-open protection box 2, the upper glass transparent plate 5 and the front glass transparent plate 6 are used to protect the photovoltaic panel 4 in real time, and at the same time, it does not affect the normal operation of the photovoltaic panel 4. While ensuring the protection effect, the working efficiency of the photovoltaic panel 4 is also improved, and the adaptability of use is improved.
