Abstract

A photovoltaic support includes a first vertical upright column (110) and a second vertical upright column (120) on a foundation, and a beam (10) respectively hinged with a first end of the first vertical upright column (110) and a first end of the second vertical upright column (120). The photovoltaic support further includes a first movable connecting piece (140) provided on the foundation and connected with a second end of the first vertical upright column (110). The first movable connecting piece (140) is automatically adjusted according to the wind intensity, such that the first vertical upright column (110) moves in a vertical direction to adjust an inclination angle of the beam (130). The photovoltaic support can adjust the angle adaptively in the case of a strong wind, and restore automatically after the strong wind has passed.

First claim

What is claimed is:

1. A photovoltaic support, comprising a first upright column and a second upright column on a foundation, and a beam respectively hinged with a first end of the first upright column and a first end of the second upright column, wherein the photovoltaic support further comprises:
a first movable connecting piece provided on the foundation and connected with a second end of the first upright column, wherein the first upright column is automatically adjusted according to wind intensity, such that the first upright column is moved in a vertical direction so as to adjust an inclination angle of the beam;
a second movable connecting piece provided on the foundation and connected with a second end of the second upright column, wherein the second upright column is automatically adjusted according to a wind intensity, such that the second upright column is moved in the vertical direction so as to adjust the inclination angle of the beam;
wherein the first movable connecting piece comprises: a spring housing fixed on the foundation, wherein an inner wall of the spring housing is provided with a limiting node used for limiting a moving path of the first upright column; and a spring provided in the spring housing, wherein a first end of the spring is fixedly connected with a bottom of the spring housing, and a second end of the spring is connected with a second end of the first upright column, enabling the first upright column to be moved in a vertical direction through a compression of the spring;
wherein the second end of the first upright column is provided with a limiting block connected with the second end of the spring, and the limiting block is moved between the limiting node and a top of the spring housing through a stretch out and draw back of the spring so as to enable the first upright column to move in the vertical direction;
the limiting block of the first upright column contacts with the top of the spring housing of the first movable connecting piece in an initial position, so that the spring of the first upright column cannot be stretched under a limitation of the spring housing of the first upright column and the limiting block; the beam has an inclination angle in an initial installation of the photovoltaic support;
wherein the first movable connecting piece and the second movable connecting piece have a same structure; correspondingly, the second movable connecting piece comprises:
a spring housing fixed on the foundation, wherein an inner wall of the spring housing is provided with a limiting node used for limiting a moving path of the second upright column; and
a spring provided in the spring housing, wherein a first end of the spring is fixedly connected with a bottom of the spring housing, and a second end of the spring is connected with a second end of the second upright column, enabling the second upright column to be moved in a vertical direction through a stretch out and draw back of an elastic force;
wherein the second end of the second upright column is provided with a limiting block connected with the second end of the spring, and the limiting block is moved between the limiting node and a top of the spring housing through a stretch out and draw back of the spring so as to enable the second upright column to move in the vertical direction;
the limiting block of the second upright column contacts with a limiting node of the spring housing of the second movable connecting piece in an initial position, so that a corresponding spring cannot be compressed.

2. The photovoltaic support as claimed in claim 1 , further comprising:
a slide connecting piece, wherein a hinging position of a first end of the second upright column and the beam is connected by the slide connecting piece, and the beam is moved in a horizontal direction through the slide connecting piece.

3. The photovoltaic support as claimed in claim 2 , wherein the slide connecting piece comprises: a slide rail provided on the beam, a first hinging head provided in the slide rail, and a second hinging head provided at the first end of the second upright column and hinged with the first hinging head, wherein the first hinging head is moved in the slide rail such that the beam is moved in the horizontal direction relative to the first hinging head.
