Description

Technical Field

[0001] The utility model relates to, but is not limited to, the technical field of photovoltaic cables. Specifically, it relates to a support structure for a fishing-light complementary photovoltaic cable bridge. Background Technique

[0002] In general, the AC and DC cables and the collector line cables of photovoltaic projects are directly buried underground. When the direct burial form cannot be adopted due to geological conditions, such as when the fishing-light complementary photovoltaic cables pass over the water surface or the agricultural-light complementary photovoltaic cables cannot be directly buried underground due to planting requirements, measures need to be taken to place the cables on a raised support structure. In previous projects, a hanging bracket or a triangular hoop structure was used, which has a certain height from the water surface and the ground and does not affect the subsequent aquaculture and planting operation requirements.

[0003] The hanging bracket structure scheme is to use sling ropes to connect to the purlins at both ends of the module. The lower part of the sling ropes is connected to the crossbeam, and the two sling ropes and the crossbeam are fixedly connected by buckles. Then, the cable bridge is placed on the crossbeam. This hanging bracket structure form has a relatively low stiffness of the sling ropes, and has a large deformation under the action of wind load, which may cause the cable bridge to fall off or be damaged. In addition, installing the sling ropes on the purlins increases the additional load and has an adverse impact on the strength and stability of the purlins. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the defects of the prior art and provide a support structure for a fishing-light complementary photovoltaic cable bridge.

[0005] To solve the above technical problem, the utility model provides the following technical solutions:

[0006] A support structure for a fishing-light complementary photovoltaic cable bridge of the utility model includes a pile foundation, a cable bridge hoop, an angle steel, a channel steel crossbeam, and a cable trough box. Two cable bridge hoops are arranged on the outer side of the pile foundation. The angle steel is arranged between the two cable bridge hoops. The channel steel crossbeam is arranged at the upper end of the angle steel and is connected by bolts. The cable trough box is arranged on the upper surface of the channel steel crossbeam;

[0007] The cable bridge hoop includes a fastening plate and an elastic plate. The fastening plate is located inside the cable bridge hoop, and the elastic plate is arranged between the cable bridge hoop and the fastening plate.

[0008] As a preferred technical solution of the utility model, two angle steels are arranged on one side of the cable bridge hoop. One of the angle steels is horizontally arranged, one end of which is bolted to the cable bridge hoop, and the other end is bolted to the upper end of the other angle steel.

[0009] As a preferred technical solution of the present utility model, the other end of the other angle steel is bolted to the bridge bracket located below, and the two angle steels and one side of the bridge bracket are designed in a triangle shape.

[0010] As a preferred technical solution of the present utility model, the ends of the fastening plate and the elastic plate are both welded to the inner side of the bridge bracket, and there is a gap between the rear side of the elastic plate and the bridge bracket, and the gap is an expansion joint.

[0011] As a preferred technical solution of the present utility model, a spring is arranged in the expansion joint, and both ends of the spring are fixedly connected to the elastic plate and the bridge bracket respectively.

[0012] As a preferred technical solution of the present utility model, the elastic plate is made of one of aluminum alloy or stainless steel, and the fastening plate is made of rubber material.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] The present utility model adopts a double-triangle support structure design composed of angle steels. This structure design has a larger stiffness and better stability. The photovoltaic cable is directly fixed on the pile foundation through the cross beam, the triangular support and the bracket, and the elastic structure design of the bracket is utilized to improve the firmness of the bracket and reduce the situation of the bracket falling off. It solves the problems that the sling stiffness of this hanger structure form is relatively low, and it deforms greatly under the action of wind load, which may cause the bridge bracket to fall off or be damaged. In addition, installing the sling on the purlin increases the additional load and has an adverse impact on the strength and stability of the purlin.

[0023] As Figures 1-4 shown, the present utility model provides a support structure for a fishing-light complementary photovoltaic cable bridge, including a pile foundation 100, a bridge support clamp 200, angle steel 300, a channel steel cross beam 400, and a cable trough box 500. There are two bridge support clamps 200 arranged on the outer side of the pile foundation 100. The angle steel 300 is arranged between the two bridge support clamps 200. The channel steel cross beam 400 is arranged at the upper end of the angle steel 300 and is connected by bolts. The cable trough box 500 is arranged on the upper surface of the channel steel cross beam 400;

[0024] The bridge support clamp 200 includes a fastening plate 201 and an elastic plate 202. The fastening plate 201 is located inside the bridge support clamp 200, and the elastic plate 202 is arranged between the bridge support clamp 200 and the fastening plate 201.

[0025] Further, in this embodiment, there are two angle steels 300 arranged on one side of the bridge support clamp 200. One of the angle steels 300 is horizontally arranged, one end of which is bolted to the bridge support clamp 200, and the other end is bolted to the upper end of the other angle steel 300.

[0026] In this embodiment, the other end of the other angle steel 300 is bolted to the bridge support clamp 200 located below. The two angle steels 300 and one side of the bridge support clamp 200 are designed in a triangular shape. By connecting the two angle steels 300, the bridge support clamp 200, the angle steel 300, and the pile foundation 100 form a triangular structure. Based on the fact that this structure is arranged on both the left and right sides of the bridge support clamp 200, a double-triangular support structure is formed.

[0027] In this embodiment, the ends of the fastening plate 201 and the elastic plate 202 are both welded to the inner side of the bridge bracket 200. There is a gap between the rear side of the elastic plate 202 and the bridge bracket 200, and the gap is an expansion joint. The elastic fastening is carried out through the fastening plate 201 and the elastic plate 202 when the bridge bracket 200 is connected to the pile foundation 100.

[0028] In this embodiment, a spring 204 is arranged in the expansion joint. The two ends of the spring 204 are respectively fixedly connected to the elastic plate 202 and the bridge bracket 200, and the elastic fastening effect is improved through the spring 204.

[0029] In this embodiment, the elastic plate 202 is made of one of aluminum alloy or stainless steel, and the fastening plate 201 is made of rubber. Through the material of the elastic plate 202, it has elasticity while having strength. Through the fastening plate 201, it can deform according to the shape of the pile foundation 100 and better fit the pile foundation 100.

[0030] Specifically, in order to make the stability of the bridge support structure better and the deformation relatively smaller, a structural form with a larger stiffness needs to be adopted. At the same time, the installation position of the support structure needs to be changed so that the main structure is less affected by the additional load. Therefore, two bridge brackets 200 are installed on each of the pile foundations 100 on both sides of the photovoltaic support. The connection between the bridge bracket 200 and the pile foundation 100 is composed of a triangular support by using the angle steel 300, which are respectively bolted to the two bridge brackets 200 and arranged on both sides of the pile foundation 100. The channel steel cross beam 400 is bolted to the angle steels 300 on both sides, and the photovoltaic cable bridge is fixed on the channel steel cross beam 400. By using the original photovoltaic support pile foundation 100, the number of pile foundations 100 is reduced, the land utilization rate is reduced, the impact on subsequent economic production is small, the construction cost is saved, and a structural form with a larger stiffness is adopted. At the same time, the installation position of the support structure needs to be changed so that the main structure is less affected by the additional load;

[0031] Considering the problem that the conventional bridge bracket 200 is prone to looseness after a long time, a fastening plate 201 is arranged on the inner side of the bridge bracket 200 to be connected to the pile foundation 100. When the elastic fastening plate 201 comes into contact with the pile foundation 100 and deforms, the rear elastic plate 202 and the spring 204 are squeezed and deformed. Based on the elastic force, the fastening plate 201 is pressed against the outer surface of the pile foundation 100, and the bridge bracket 200 itself is fastened by bolts, so that the connection between the bridge bracket 200 and the pile foundation 100 is more firm and not easy to fall off.

[0032] Components such as the pile foundation 100, bridge bracket hoop 200, fastening plate 201, elastic plate 202, spring 204, angle steel 300, channel steel cross beam 400, and cable trough box 500 of the present utility model are all common standard components or components known to those skilled in the art. Their structures and principles can all be learned by those skilled in the art through technical manuals or obtained through conventional experimental methods.
