DETAILED DESCRIPTION

[0030] The following description provides many different embodiments or examples for implementing different features of the present invention. The components and arrangements described in the following specific examples are only used to simplify the present invention and are only used as examples, not to limit the present invention.

[0031] In the description of the present invention, the terms "first" and "second" are used only for descriptive purposes and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0032] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] This embodiment provides a photovoltaic panel fixing device, such as Figure 1-Figure 3As shown, it includes an H-shaped fixing frame 10, and the H-shaped fixing frame 10 includes a supporting portion 11 and a connecting portion 12, and both ends of the connecting portion 12 are connected to the supporting portion 11; the connecting portion 12 is provided with a connecting groove 20, and both ends of the connecting groove 20 are provided with a sliding groove 30, and a first buffer structure 40 and a sliding block 50 are provided in the sliding groove 30, and one end of the first buffer structure 40 is connected to the sliding groove 30, and the other end is connected to the sliding block 50;

[0034] A second buffer structure 60 is connected to the middle of the connecting groove 20, and the second buffer structure 60 is connected to a bracket 70. The brackets 70 on both sides of the second buffer structure 60 are movably connected to auxiliary rods 80, and the auxiliary rods 80 are movably connected to the slider 50; specifically, the two ends of the auxiliary rod 80 are hinged to the slider 50 and the bracket 70 respectively.

[0035] The slide groove 30 is realized by setting a limit plate 120 in the connecting groove 20 .

[0036] Principle of use: During use of the device, the four corners of the H-shaped fixing frame 10 are fixed on the ground, and then the photovoltaic panel is connected to the bracket 70; when the photovoltaic panel encounters strong winds, the second buffer structure 60 and the deformation of the second buffer structure 60 buffer the impact force of the strong wind on the photovoltaic panel, thereby protecting the photovoltaic panel and the fixing device and increasing the service life of the photovoltaic panel and the fixing device.

[0037] Furthermore, the bracket 70 is set to be U-shaped. The U-shaped bracket 70 has a simple structure, which not only reduces the use of materials, but also has the advantages of light weight and small area. When encountering strong winds, the impact force is reduced due to the reduction in weight and area.

[0038] It should be noted that the structure of the bracket 70 is not limited to the above-mentioned manner listed in the embodiment of the present invention, and other forms of brackets 70 should also be within the protection scope of the present invention.

[0039] Furthermore, if Figure 2 As shown, a folding sealing cover 90 is provided in the slide groove 30 , and the two ends of the folding sealing cover 90 in the length direction are fixedly connected to the slide groove 30 and the slider 50 respectively, and the two end surfaces of the folding sealing cover 90 in the width direction are adapted to the inner surface of the slide groove 30 .

[0040] The first buffer structure 40 includes the following three types:

[0041] (1) Figure 3As shown, the first buffer structure 40 includes a first outer sleeve 41, a first inner sleeve 42 and a first spring 43. The first outer sleeve 41 is provided with the first spring 43, the first spring 43 is connected to the first inner sleeve 42, and the first inner sleeve 42 cooperates with the first spring 43 to achieve the expansion and contraction of the first inner sleeve 42. This buffer structure can not only achieve a buffering effect, but also has a self-protection effect to avoid the influence of dust and the like.

[0042] (2) Figure 3 , Figure 4 As shown, the first buffer structure 40 includes a first outer sleeve 41, a first inner sleeve 42 and a first spring 43. The first outer sleeve 41 is provided with the first spring 43, the first spring 43 is connected to the first inner sleeve 42, and the first inner sleeve 42 cooperates with the first spring 43 to realize the extension and retraction of the first inner sleeve 42;

[0043] A second spring 100 is further disposed in the slide groove 30 , and the second spring 100 is disposed outside the first buffer structure 40 . One end of the second spring 100 is connected to the slide groove 30 , and the other end is connected to the slider 50 .

[0044] (3) The first buffer structure 40 includes a second spring 100 , one end of the second spring 100 is connected to the side wall of the slide groove 30 , and the other end is connected to the slider 50 .

[0045] Among them, the second structure can achieve greater wind impact buffering and has better

[0046] However, since the external second spring 100 is provided, if too much dust or the like is accumulated in the chute 30, the deformation of the second spring 100 will be hindered, so that the second buffer structure 60 cannot achieve its buffering function. The folding sealing cover 90 can prevent dust or the like from entering the chute 30, prevent the accumulated dust from hindering the second spring 100, and improve the service life and effect of the second buffer structure 60.

[0047] Preferably, the inner diameter of the first outer sleeve 41 is matched with the inner diameter of the first inner sleeve 42. Based on this, while achieving the buffer function, it also has a better self-protection effect.

[0048] Furthermore, if Figure 5 As shown, the cross section of the foldable sealing cover 90 is a plurality of V-shaped sections connected together. Based on this, it has the advantages of simple structure and easy manufacturing.

[0049] Furthermore, if Figure 2As shown, the second buffer structure 60 includes a second outer sleeve 61, a second inner sleeve 62 and a third spring 63. The third spring 63 is arranged in the second outer sleeve 61, and the third spring 63 is connected to the second inner sleeve 62. The second inner sleeve 62 cooperates with the third spring 63 to realize the expansion and contraction of the second inner sleeve 62. Based on this, while realizing the buffer function, it also has a self-protection function.

[0050] Preferably, the inner diameter of the second outer sleeve 61 is matched with the inner diameter of the second inner sleeve 62. Based on this, while achieving the buffer function, it also has a better self-protection effect.

[0051] Furthermore, the two first buffer structures 40 and the second buffer structure 60 are both located on the same straight line. Because the first buffer structure 40 and the second buffer structure 60 are both arranged in the connecting groove 20, the first buffer structure 40 and the second buffer structure 60 located in the connecting groove 20 are on the same straight line. Based on this, the impact force can be buffered more evenly, the damage of the fixing device of the present invention can be avoided, and the service life of the fixing device can be increased.

[0052] Furthermore, the H-shaped fixing frame 10 is provided with fixing holes 110 , which facilitates the installation and fixing of the H-shaped fixing frame 10 .

[0053] Furthermore, the bracket 70 is provided with a mounting hole, and the mounting hole is used to install the photovoltaic panel.

[0054] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein; and these modifications or substitutions do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
