[0002] As the core part of the solar power generation system, solar panels convert the sun's radiation into electrical energy. Therefore, solar panels need to be installed outdoors, such as on roofs where they can fully receive sunlight. In order to receive more radiation energy, solar panels have a large surface area and are mostly flat, which makes them more affected by wind. Therefore, their fastening devices need to have strong positioning capabilities and structural strength.

[0003] The existing solar panel fastening device lacks a shock-absorbing function, which causes the fastening device parts to become loose after the solar panel is subjected to a large impact force brought by strong winds for a long time.

DETAILED DESCRIPTION

[0020] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0021] like Figure 1 and Figure 3 As shown, a solar panel fastening device includes a substrate 1 and a fastening clamp 12. A slide groove 2 is provided on the surface of the substrate 1. A sliding pin 3 is provided in the slide groove 2 at the front and rear ends. A sliding pin 4 is provided in the slide groove 2 at the left and right ends. A connecting rod 11 is fixed to the top of the sliding pin 4. The fastening clamp 12 is provided at the other end of the connecting rod 11. A shock absorbing assembly 13 is installed inside the fastening clamp 12. Four slide grooves 2 are provided, and the ratio of the number of the slide grooves 2, the sliding pin 3 and the sliding pin 4 is 2:1: 1, the bottoms of the sliding pin 1 3 and the sliding pin 2 4 are both connected with a connecting block 5, and the surface of the connecting block 5 is connected with a supporting arm 6 through a rotating shaft, the other end of the supporting arm 6 is connected with a fixing block 7 through a rotating shaft, and a bottom plate 8 is fixed to the bottom of the fixing block 7, an electric push rod 9 is installed at the middle end of the bottom of the base plate 1, and the bottom plate 8 is arranged at the output end of the electric push rod 9, a fastening clamp 10 is installed on the top of the sliding pin 1 3, and the fastening clamp 10 and the fastening clamp 2 12 are perpendicular to each other, and a shock absorbing component 13 is also arranged inside the fastening clamp 10.

[0022] The specific operation is as follows: the electric push rod 9 extends to drive the base plate 8 and the fixed block 7 to descend, and the rotation of the support arm 6 causes the sliding pin 1 3 and the sliding pin 2 4 fixed to the connecting block 5 to slide in the corresponding sliding groove 2 until the pressure sensor 1308 contacts the solar panel, so that the solar panel is fixed in the frame structure formed by the fastening clamp 10 and the fastening clamp 2 12.

[0023] like Figure 2As shown, the shock absorbing assembly 13 includes a fixed frame 1301, a pump 1 1302, a return spring 1303, a pump 2 1304, a shock absorbing airbag 1305, a scissor frame 1306, a movable frame 1307 and a pressure sensor 1308, and the pump 1 1302 is arranged at both ends of the inner side of the fixed frame 1301, the side of the pump 1 1302 is connected to the return spring 1303, and the other end of the return spring 1303 is connected to the pump 2 1304, and the pump 1 1302 is arranged at both ends of the inner side of the fixed frame 1301. The output ends of the first and second pumps 1304 are both connected to shock-absorbing airbags 1305, and the pull rod of the first pump 1302 is connected to the pull rod of the second pump 1304 through a scissor frame 1306. A movable frame 1307 is arranged on the outside of the second pump 1304, and a pressure sensor 1308 is installed on the middle end of the side of the movable frame 1307. The fixed frame 1301 is fixedly connected to the fastening clamp 10 and the fastening clamp 2 12 respectively, and the number of the first pump 1302 and the second pump 1304 is the same.

[0024] The specific operation is as follows. Due to the large size and weight of the solar panel, it will generate squeezing force on the return spring 1303 when encountering strong winds, thereby changing the width of the scissor frame 1306 so that the pull rod is pushed into the air pump 1 1302 and the air pump 2 1304 accordingly. By injecting gas into the shock-absorbing airbag 1305, the shock-absorbing airbag 1305 replaces the hard contact to reduce the impact of vibration on the solar panel, thereby extending the service life of the solar panel.

[0025] In summary, when the solar panel fastening device is used, the solar panel is first placed horizontally above the base plate 1, and then the electric push rod 9 is controlled to extend to drive the bottom plate 8 and the fixing block 7 to descend, so that the support arm 6 rotates on the fixing block 7 and causes the sliding pin 1 3 and the sliding pin 2 4 fixed to the connecting block 5 to slide in the corresponding sliding groove 2. When the pressure sensor 1308 detects the pressure on the solar panel, the solar panel is pressed by the fastening clamp 1 10 and the fastening clamp 2 12 around it, thereby completing the fixation of the solar panel;

[0026] Due to the large size and weight of the solar panel, the solar panel will vibrate when encountering severe weather such as strong wind, rain and snow, and the vibration will produce a squeezing force on the return spring 1303, so that the moving frame 1307 slides along the inside of the fastening clamp 10 and the second fastening clamp 12, and the width of the scissor frame 1306 changes, that is, the pull rod is driven to push into the air pump 1 1302 and the second air pump 1304 respectively, and the gas in the air pump 1 1302 and the second air pump 1304 is injected into the shock-absorbing airbag 1305, and the shock-absorbing airbag 1305 expands to achieve a buffering effect, thereby avoiding the solar panel from being damaged by hard contact with the fastening clamp 10 and the second fastening clamp 12, and at the same time ensuring the integrity of the parts structure;

[0027] When the solar panel needs to be inspected, the electric push rod 9 is controlled to retract to drive the bottom plate 8 and the fixed block 7 to rise, so that the support arm 6 rotates on the fixed block 7 and causes the sliding pin 1 3 and the sliding pin 2 4 fixed to the connecting block 5 to slide in the corresponding sliding groove 2, so that the fastening clamp 1 10 and the fastening clamp 2 12 are away from the solar panel. The whole disassembly process is very simple, which effectively reduces the inspection time of the solar panel.

[0028] The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
