Detailed Description

The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so as to enable those skilled in the art to more easily understand the advantages and features of the present invention, and thereby define the scope of the invention more clearly and clearly.

Examples

Referring to fig. 2, the embodiment provides a photovoltaic support middle support structure, which includes an upright 1 and a diagonal brace 2 disposed on the upright 1 and inclined toward the south, where the diagonal brace 2 is fixed at the upper end of the upright 1, and the diagonal brace 2 and the upright 1 are secondarily reinforced by using a reinforcing rib 3, so as to enhance the firmness of the diagonal brace 2 on the upright 1. In this embodiment, retaining rings are arranged at the upper, middle and lower end points of the diagonal brace 2, and are used for stretching, pulling and fixing the steel strands (at least two steel strands are required for placing the photovoltaic module). The bottom of the upright post 1 is fixedly connected with a swing mechanism 5, so that the upright post 1 can swing along the direction of the steel strand, and the swing mechanism 5 is fixed on the ground.

Because China is in a northern hemisphere, the distribution direction of the steel strands is in an east-west direction, and the vertical column 1 swings in the east-west direction. In order to increase the overall stability of the upright post 1, an inclined support rod 4 is arranged on the outer side of the upright post 1, the inclined support rod 4 is arranged in the north-south direction, and the upper end of the inclined support rod 4 is hinged to the upper end of the upright post 1, and the lower end of the upright post is fixed on the ground, so that a stable triangular structure is formed among the inclined support rod 4, the upright post 1 and the ground.
