The above-mentioned nut is screwed on the other end of the bolt, the ground plate, the elastic element and the middle pressure block are all set on the bolt, and are located between the nut and the bolt head, one end of the elastic element is in contact with the middle pressure block, and the other end is in contact with the ground The above-mentioned middle pressure block has at least one hook, and the grounding piece has at least one wing that fits with the hook on one side and can contact the guide rail for photovoltaic module installation on the other side. The sheet and the corresponding hook form a clamping groove for clamping the end of the photovoltaic module.

Furthermore, in order to make the upper and lower sides of the grounding piece penetrate the photovoltaic module and the guide rail for installing the photovoltaic module respectively, and form a good contact, the upper and lower sides of the wing of the grounding piece are respectively provided with flanging burrs.

Further, in order to facilitate the placement of the grounding sheet, the two ends of the grounding sheet are respectively provided with installation guide wings.

Further, the middle pressure block has two hooks, and the ground piece has two fins.

Further, the elastic element is a spring.

After adopting the above-mentioned technical scheme, the ground plate in this fixing device acts as a limiter for the elastic element. During the installation process, the bolt head of the bolt can be conveniently embedded in the installation groove of the guide rail under the action of the installation force and the elastic force change, and the elastic element It can maintain a certain compression force, and can deform and expand under a certain force, so that the middle pressure block is in a position convenient for installing photovoltaic modules, and realizes the functions of pre-installation and convenient position adjustment. The ground plate is also connected with photovoltaic modules and photovoltaic modules The installation guide rails are in contact with each other to realize the grounding function. This fixing device cleverly uses the deformation principle of the grounding plate and the elastic element, which not only achieves the function of using the grounding plate to naturally realize the grounding during the installation process of the photovoltaic module, but also reduces the subsequent system grounding. The workload and the cost of grounding materials, and at the same time, the limiting function of the grounding piece to the elastic element is used to realize the pre-positioning of the pressing block during the installation process, so that the entire fixing device is in a state of easy installation, which facilitates the fixing of photovoltaic modules installation, improving installation efficiency.

Detailed ways

In order to make the content of the utility model easier to understand clearly, the utility model will be further described in detail below according to the specific embodiments and in conjunction with the accompanying drawings.

As shown in Figures 1 and 2, a photovoltaic module fixing device with a grounding function includes a bolt 1, a grounding piece 2, an elastic element 3, a middle pressure block 4 and a nut 5, and one end of the bolt 1 has a bolt head 1- 1. The nut 5 is screwed on the other end of the bolt 1. The ground plate 2, the elastic element 3 and the middle pressure block 4 are all set on the bolt 1, and are located between the nut 5 and the bolt head 1-1. One end of the elastic element 3 It abuts against the middle pressure block 4, and the other end abuts against the ground piece 2. The middle pressure piece 4 has at least one hook 4-1, and the ground piece 2 has at least one side that matches the hook 4-1 and the other side The fin 2-1 which can be in contact with the guide rail 9 for installing the photovoltaic module, the fin 2-1 and the corresponding hook 4-1 form a clamping groove 24 for clamping the end of the photovoltaic module. The bolt head 1-1 can be a T-shaped structure.

In order to make the upper and lower sides of the grounding sheet 2 pierce the photovoltaic module and the guide rail for installing the photovoltaic module respectively to form a good contact, as shown in Figures 1 and 2, the upper and lower sides of the wings 2-1 of the grounding sheet 2 Flange burrs 2-1-1 are respectively arranged on both sides.
