Description

Technical Field

[0001] This utility model relates to the field of photovoltaic technology, specifically to a wire clip fixing device. Background Technology

[0002] With the growth of photovoltaic (PV) installations, most mountainous and desert areas with favorable conditions have already been developed into PV power plants. Furthermore, the government is imposing increasingly strict regulations on farmland and forest land, making most current PV power plant sites quite challenging. Conventional fixed PV supports are no longer sufficient to meet the needs of mountainous PV power plant construction. In mountainous projects, to adapt to complex terrain such as ravines, valleys, and rivers; and in fish-solar hybrid projects, to minimize the impact of PV on aquaculture, owners require PV support pile spacing to be as large as possible. Flexible PV supports, with their large span and lightweight structure, can well adapt to complex mountainous and fishpond projects. Therefore, developing flexible PV supports is a key development direction and an inevitable trend in the PV industry.

[0003] Achieving a stable connection between the steel strands and the struts is a direction that is constantly being optimized in the design process of flexible photovoltaic supports.

[0004] Chinese patent CN217984896U discloses a node structure for a linkage stabilization system for photovoltaic flexible supports. In this patent, the double-headed strut fixing component and the double-headed strut fixing back plate are connected by vertically set bolts to form a channel for clamping steel strands. Due to the vertically set bolt structure, installation space needs to be reserved in the area above the steel strands. Therefore, the connection between the steel strands and the struts needs to be achieved at a position that avoids the photovoltaic modules.

[0005] Furthermore, the double-headed strut fixing component requires three bolts to connect the three struts separately, making it impossible to achieve a unified connection of the three struts using a single bolt. Utility Model Content

[0006] In view of the problems existing in the prior art, this utility model provides a photovoltaic flexible bracket steel strand clamp fixing device to solve at least one of the above technical problems.

[0007] To achieve the above objectives, this utility model provides a photovoltaic flexible bracket steel strand clamp fixing device, including a support rod connector for connecting the support rod and a wire clamp for connecting the steel strand, characterized in that the wire clamp includes a first clamping member and a second clamping member that can be detachably assembled from the left and right sides;

[0008] Both the first clamping member and the second clamping member include a clamping part and a connecting part arranged vertically. The clamping part is used to clamp the steel strand, and the connecting part is used to detachably connect the support rod connector.

[0010] The middle part has a mounting hole for inserting a mounting bolt, and the strut connector is connected to the strut through the mounting bolt;

[0012] The left mounting portion and the right mounting portion are located on both sides of the connecting portion of the first clamping member and the connecting portion of the second clamping member. The first clamping member, the second clamping member, the left mounting portion, and the right mounting portion are connected by transverse bolts.

[0013] This invention enables the connection of multiple struts with a single mounting bolt. The strut connector and wire clamp are connected via a horizontal screw, eliminating the need for pre-reserved installation space above the steel strand and allowing connection between the steel strand and strut without obstructing the photovoltaic modules.

[0014] More preferably, the top of the clamping portion of the first clamping member is provided with an extension portion extending to the right, the extension portion having a slot, and the lower end of the slot being open;

[0016] More preferably, the protrusion is a strip-shaped protrusion with its length direction being the front-to-back direction;

[0017] The slot is a strip-shaped groove with its length direction running from front to back.

[0018] More preferably, the top surface of the clamping portion of the first clamping member is a cylindrical curved surface.

[0019] More preferably, the connecting portion of the first clamping member and the second clamping member is provided with a slot for longitudinally inserting the strut connector, and the upper end surface of the slot abuts against the top surface of the strut connector.

[0020] More preferably, both ends of the connecting portion of the first clamping member and the second clamping member are provided with through holes for the transverse bolt to pass through.

[0023] It facilitates the installation of countersunk bolts.

[0024] More preferably, the support rod is provided in three parts, namely a first support rod, a second support rod, and a third support rod;

[0025] The first, second, and third support rods are all provided with through holes through which the mounting bolts pass.

[0026] More preferably, a washer is sandwiched between the strut and the strut connector, and the washer passes through the mounting bolt.
