[0030] Figure 1 The photovoltaic array 1 provided by the utility model is shown. Figure 1 As shown, an embodiment of the photovoltaic array 1 of the utility model includes a plurality of photovoltaic modules 20 and a photovoltaic bracket 10. The photovoltaic bracket 10 is used to support the photovoltaic modules 20. In a photovoltaic array 1, there are a plurality of photovoltaic brackets 10, which can support and fix a plurality of photovoltaic modules 20.

The size of the array and the number of brackets can be flexibly adjusted according to the requirements of transportation and installation, and are not limited to the parameters in this embodiment.

[0031] In one embodiment, the photovoltaic bracket 10 is arranged on a ground foundation 30. In the east-west direction, the photovoltaic brackets 10 of the same array are connected to the ground foundation 30, so that the entire bracket array is installed on one ground foundation 30, and the bracket array foundation part forms a whole. Further, the ground foundation 30 is a basic structure for fixed connection with the ground, the basic structure is arranged in the east-west direction, and the basic structure is connected to each photovoltaic bracket 10. The basic structure can be a frame structure composed of square tubes, round tubes, C-shaped steel or polygonal tubes.

[0032] Figure 2 and Figure 3 The overall structure of an embodiment of a photovoltaic support 10 provided by the utility model is shown. Figure 2 The arrows shown indicate the movable direction of the photovoltaic support 10. The photovoltaic support 10 includes a support structure 100 for supporting the photovoltaic assembly 20. The support structure 100 includes an inclined beam 110 and a purlin 120 for connecting the photovoltaic assembly 20 and the inclined beam 110.

In one embodiment, the inclined beam 110 is a square tube, a round tube, a C-shaped steel or a polygonal tube, and the upper opening is connected to the purlin 120, and the inclined beam 110 is arranged in the north-south direction in the photovoltaic support 10. By changing the angle between the photovoltaic support 10 and the horizontal plane, the installation inclination angle α of the photovoltaic module 20 in the north-south direction and the horizontal plane can be changed.

[0033] like Figure 2As shown, the photovoltaic support 10 provided by the utility model also includes a first support structure 200, one end of the first support structure 200 is used to be fixedly connected to the ground foundation 30, and the other end is hinged to the inclined beam 110. The photovoltaic support 10 also includes a second support structure, and the second support structure includes a first support member 310, a second support member 320 and a third support member 330. The first end 311 of the first support member 310 and the first end 321 of the second support member 320 are both hinged to the inclined beam 110, and the second end 312 of the first support member 310 and the second end 322 of the second support member 320 are both hinged to the first end 331 of the third support member 330 to form a connection point A.

At least one of the first support member 310, the second support member 320 and the third support member 330 is configured to be axially retractable to change the installation inclination angle α between the photovoltaic component 20 and the horizontal plane, so that the photovoltaic bracket 10 can be switched between the unfolded state and the folded state. Among them, the installation inclination angle α of the photovoltaic bracket 10 in the unfolded state is greater than the installation inclination angle α of the photovoltaic bracket 10 in the folded state.

[0034] The photovoltaic bracket 10 of the utility model changes the installation inclination angle α of the photovoltaic module 20 through at least one axially retractable support member, which is conducive to flexible adjustment of the installation inclination angle α, so that the photovoltaic bracket 10 can adjust the axially retractable support member after being transported to the designated location, and quickly unfold from the folded state to increase the inclination angle of the photovoltaic module 20 to a predetermined angle, thereby saving on-site installation volume and improving installation efficiency; and the bracket can be folded from the unfolded state when it needs to be moved or recovered. After folding, the installation inclination angle α is smaller, which is convenient for handling and transportation, and can meet the requirements of rapid installation, rapid recovery and transportation.

[0035] In one embodiment, the base structure is fixedly connected to the first support structure 200 of each photovoltaic support 10, and is hinged to the second end 332 of the third support member 330. In the north-south direction, the first support structure 200 is connected to the base structure, and the third support member 330 is connected to the base structure.

When the photovoltaic bracket 10 is in the unfolded state, the installation inclination angle α of the photovoltaic assembly 20 is relatively large, which is conducive to increasing the amount of radiation received by the light-receiving surface of the photovoltaic assembly 20. In the folded state, the installation inclination angle α of the photovoltaic assembly 20 is relatively small, which is convenient for movement and transportation. In order to ensure the power generation of the photovoltaic assembly 20, the above-mentioned installation inclination angle α is an acute angle, within the range of 0° to 45°, preferably 0° to 30°.

[0037] Before the photovoltaic array 1 of the present invention is installed and deployed, that is, when it needs to be moved or recovered, the photovoltaic bracket 10 is switched from the unfolded state to the folded state, so that the installation inclination angle α of the photovoltaic module 20 is adjusted to the minimum angle for easy transportation. After the photovoltaic array 1 of the present invention is transported to the designated installation site, the photovoltaic bracket 10 is switched from the folded state to the unfolded state to adjust the installation inclination angle α of the photovoltaic module 20 to other angles.
