Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic power generation, and specifically relates to a double-slope photovoltaic bracket. Background Art

[0002] Since my country is located in the northern hemisphere, most photovoltaic project components are arranged facing south. However, in low-latitude areas, due to the small direct sunlight angle and taking into account factors such as the project land area and construction cost, photovoltaic components need to be arranged on a double slope facing east and west to ensure the project's rate of return.

[0003] At present, most photovoltaic project projects use traditional single-slope photovoltaic brackets for component arrangement, and rarely use photovoltaic bracket systems for double-slope component arrangement. If the traditional single-slope non-lateral displacement double-column bracket system is used to form two sets of separately oriented bracket systems in a mirror-image manner, on the one hand, the structural integrity is poor and it is easy to shift laterally under load. On the other hand, two sets of inter-column supports need to be set up, the amount of steel used is relatively high, and the material utilization rate is low. Utility Model Content

[0004] The utility model provides a double-slope photovoltaic bracket to solve the problem of lateral shift of the photovoltaic brackets in the prior art when the photovoltaic brackets are arranged on the double slopes.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A double-slope photovoltaic support, comprising: at least two photovoltaic support groups with photovoltaic modules, purlins and cross tie rods;

[0007] The photovoltaic support group includes: an inclined beam, a column, a strut and a mounting assembly, wherein the inclined beam is arranged on both sides of the top of the ramp, the columns are respectively fixed under the inclined beams on both sides of the top of the ramp and in contact with the ground, and the strut is cross-arranged between the columns near the top of the ramp through the mounting assembly;

[0008] The oblique beams of a plurality of photovoltaic support groups are connected by purlins, and the upright posts of adjacent photovoltaic support groups are connected by cross tie rods.

[0009] In some embodiments, the mounting assembly includes: a clamp and a bolt connector, the clamp is arranged below the connection between the column and the inclined beam, and the clamp is connected to the column and the support rod through the bolt connector.

[0010] In some embodiments, the cross-arranged struts are welded at their connections.

[0011] In some embodiments, at least two columns are provided, and the number of columns located under the inclined beams on both sides of the top of the ramp is equal.

[0012] In some embodiments, the columns located under the inclined beams on both sides of the top of the ramp are symmetrically fixed.

[0013] In some embodiments, a cross tie rod is correspondingly provided on each photovoltaic support group.

[0014] In some embodiments, the inclined beams are symmetrically arranged on both sides of the top of the ramp.

[0015] In some embodiments, the pillars are spaced apart by a preset distance.

[0016] In some embodiments, the preset distance between the columns of the support pole is less than or equal to the preset distance between other adjacent columns.

[0017] In some embodiments, a plurality of purlins are provided, and the purlins are parallel to each other.

[0018] Compared with the prior art, the utility model has the following beneficial effects:

[0019] The utility model discloses a double-slope photovoltaic support, including a photovoltaic support group, purlins and cross-tension rods in which photovoltaic components are arranged. The photovoltaic support group includes an inclined beam, a column and a strut. The inclined beam is arranged on both sides of the top of the ramp. The columns are respectively fixed under the inclined beams on both sides of the top of the ramp and in contact with the ground. The struts are cross-arranged between the columns near the top of the ramp. The inclined beams of the photovoltaic support group are connected by purlins, and the columns of adjacent photovoltaic support groups are connected by cross-tension rods. Therefore, the utility model solves the problem of lateral displacement of the double-slope photovoltaic support by arranging columns in a horizontal single frame and combining the method of cross-arranging struts between the middle columns. In addition, the columns are connected by arranging cross-tension rods between adjacent photovoltaic support groups arranged longitudinally on the double-slope photovoltaic support, which can further ensure the stability of the double-slope photovoltaic support structure.

[0020] Furthermore, the utility model has at least two columns, and the number of columns located under the inclined beams on both sides of the top of the ramp is equal, the columns on both sides are symmetrically fixed, and the inclined beams are also symmetrically arranged. The utility model performs anti-lateral displacement verification through a photovoltaic bracket simulation calculation module. The lateral displacement angles under the action of seismic loads and wind loads are infinitesimal (1 / 9999). Therefore, the utility model is a non-lateral displacement structure and can solve the problem of lateral displacement of double-slope photovoltaic brackets. BRIEF DESCRIPTION OF THE DRAWINGS
