Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic brackets, in particular to a double-row flexible photovoltaic bracket applicable to mountainous areas. Background Technique

[0002] The photovoltaic panel bracket is the basic frame for outdoor installation of photovoltaic panels. In the prior art, there are single-row brackets and double-row brackets. When the use requirements require a relatively wide row spacing of the brackets, the land utilization rate of the single-row flexible bracket is low and cannot meet the capacity requirements. It is necessary to use a double-row bracket to improve the overall capacity.

[0003] The utility model patent with the publication number of CN220527935U: a photovoltaic module connector and a wind-resistant double-row module flexible bracket, including a bottom plate and a V-shaped support frame. Among them, the V-shaped support frame is fixedly connected to the bottom plate; symmetrically arranged at the end of the V-shaped support frame far from the bottom plate are installation grooves for installing photovoltaic modules, and there is an angular difference between the two installation grooves in the parallel direction and the vertical direction relative to the bottom plate. In the above technical solution, by setting the V-shaped support frame, symmetrically arranged at the end of the V-shaped support frame far from the bottom plate are installation grooves for installing photovoltaic modules, and the two installation grooves are arranged at a small inclination angle; two photovoltaic modules can be arranged at a small inclination angle in opposite directions to form a triangular structure, reducing the windward area, increasing the wind pressure resistance performance, and increasing the structural stability.

[0004] Although the above utility model patent can increase the structural stability by means of a triangular structure, the structure is complex and the steel consumption is large; in the basic double-row flexible bracket in the prior art, there are two columns in the middle of each span, and the tops of the columns are connected by a through-length steel beam. The overall steel consumption cost of the bracket is high, and the use of a through-length steel beam at the top cannot be applied to complex terrains such as mountainous areas. Multiple ground anchors are used in the middle of each span, and the foundation cost is high. Therefore, there is an urgent need in the art for a double-row flexible photovoltaic bracket applicable to mountainous areas to solve the problems existing in the prior art. Content of the Utility Model

[0005] The purpose of the utility model is to provide a double-row flexible photovoltaic bracket applicable to mountainous areas to solve the technical problem of high cost of double-row flexible brackets in the prior art.

[0006] To achieve the above purpose, the utility model provides the following technical solution: a double-row flexible photovoltaic bracket applicable to mountainous areas, including two groups of end support components, a middle support component arranged between the two groups of end support components, and further including four support cables connected to the end support components at the ends. Two rows of photovoltaic panel components are installed on the four support cables, and a wind-resistant component is commonly connected and installed in the middle of the four support cables;

[0007] The middle support assembly includes a middle column foundation fixedly connected to the ground. A middle column is fixedly installed on the middle column foundation. The top of the middle column is fixedly installed with a middle column crossbeam inclined to the horizontal plane. The middle column is fixedly connected to the middle of the middle column crossbeam.

[0008] As a preferred solution, the end support assembly includes an end column. The bottom end of the end column is fixedly connected to an end column foundation, and the end column foundation is fixedly connected to the ground. The top end of the end column is fixedly connected to the end of the support cable. At least one stay cable is fixedly connected to the top end of the end column.

[0009] As a preferred solution, the end column includes a first end column, a second end column, a third end column, and a fourth end column. An end column crossbar is fixedly installed between the first end column and the second end column. An end column crossbar is fixedly installed between the third end column and the fourth end column. The end column crossbar plays a role in enhancing the structural stability. The heights of the first end column, the second end column, the third end column, and the fourth end column decrease in sequence, which is beneficial to the inclined installation of the photovoltaic panel assembly and thus beneficial to the photovoltaic panel assembly receiving light.

[0010] As a preferred solution, the wind resistance assembly includes a stabilizing angle steel. The top surface of the stabilizing angle steel is connected to the support cable in a limiting manner. At least two connecting rods are fixedly connected to the bottom surface of the stabilizing angle steel. The bottom ends of all the connecting rods are on the same straight line. A stabilizing cable is connected to the bottom ends of all the connecting rods in a limiting manner. Both ends of the stabilizing cable are fixedly connected to a stabilizing foundation, and the stabilizing foundation is fixedly connected to the ground. The wind resistance assembly indirectly pulls the support cable by using the stabilizing cable to improve the wind resistance performance of the support cable and the photovoltaic panel assembly.

[0011] As a preferred solution, the top surface of the stabilizing angle steel is connected to the support cable in a limiting manner by using a cable clamp.

[0012] As a preferred solution, the bottom ends of the connecting rods are connected to the stabilizing cable in a limiting manner by using a cable clamp.

[0013] As a preferred solution, the first end post, the second end post, the third end post, and the fourth end post are all telescopic sleeve structures, including an outer sleeve, and an inner sleeve sleeved inside the outer sleeve. The length of the inner sleeve is greater than that of the outer sleeve.

The length of the inner sleeve is greater than that of the outer sleeve. The bottom end of the outer sleeve is fixedly connected to the middle post foundation, and the top end of the inner sleeve is fixedly connected to the middle post cross beam.

[0015] As a preferred solution, the independent strut is a telescopic sleeve structure, including an outer sleeve, and an inner sleeve sleeved inside the outer sleeve. The length of the inner sleeve is greater than that of the outer sleeve. The bottom end of the outer sleeve is fixedly connected to the independent strut foundation, and the top end of the inner sleeve is fixedly connected to the diagonal strut.

[0016] Beneficial effects:

[0017] The present solution designs a double-row photovoltaic panel installation structure, which can have a larger photovoltaic panel layout capacity compared with the single-row photovoltaic panel layout solution when the use requirements have a wider requirement for the row spacing of the brackets.

[0018] In the present solution, the heights of the end posts and the middle post and the length of the independent strut of the structure can be adjusted according to the undulation of the mountain body, and it can be applicable to various terrains. The use of a separate foundation for the independent strut can reduce the length of the strut and save materials. Only one middle post is required, and combined with the independent strut, the support strength requirements can be met. Compared with the prior art using two middle posts, it not only saves materials and reduces costs, but also is more convenient for installation. Description of the drawings
