Embodiment 1

[0023] figure 1 It is a structural schematic diagram of the photovoltaic support in Embodiment 1 of the present invention. see figure 1 , a photovoltaic support 10 provided by an embodiment of the present invention includes at least two purlins 11 and at least three purlin supports 12 , and each purlin 11 has an overhang 13 . Both ends of each purlin support 12 are respectively fixed on the front column 131 and the rear column 132 , and its function is to support the purlin 11 . Wherein, the purlin 11 is fixed on the purlin support 12, and the quantity of the purlin 11 and the purlin support 12 can be set according to the actual use situation, as an example, figure 1 The number of purlins is 8, and the number of purlin supports is 4.

[0024] Specifically, there are usually multiple purlins 11 in the photovoltaic support, and the length of each purlin is the same, so the total length of each purlin can be known by calculating the total length of one of the purlins, that is,...

Embodiment 2

[0030] figure 2 It is a flowchart of a method for arranging purlins in a photovoltaic support provided in Embodiment 2 of the present invention. Wherein, the photovoltaic support includes at least two purlins and at least three purlin supports, and each purlin has a cantilever, such as figure 2 As shown, the method includes:

[0031] Step 210, calculate the total length of each purlin according to the size of the photovoltaic panel and the layout of the photovoltaic modules.

[0032] Step 220: Calculate and obtain an intermediate value according to the sum of twice the preset value and the preset number of strides.

[0033] Step 230, according to the ratio of the total length of each purlin to the median value, calculate the distance between every two purlin supports, and calculate according to the product of the distance and the preset value The length of the overhang so that the purlins are arranged based on the distance and the length of the overhang.

Abstract

The embodiment of the invention discloses a photovoltaic bracket and an arrangement method of purlines in the photovoltaic bracket. The photovoltaic bracket comprises at least two purlines and at least three purline supports, wherein each purline is provided with a cantilever, and the total length of each purline is calculated according to the size of a photovoltaic panel and the arrangement modeof photovoltaic components; among the at least two purline supports, the distance between every two purline supports is a ratio result of the total length of each purline and an intermediate value, and the intermediate value is the sum of twice a preset value and a preset span number; the length of each cantilever is a product result of the distance between every two purline supports multiplied bya preset value. The photovoltaic bracket and the arrangement method disclosed by the embodiment of the invention have the beneficial effects that in the process of supporting the photovoltaic panel,all purlines are stressed more uniformly, the internal bending moment is less, the cross section of the purline is optimum, and the raw materials are saved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of photovoltaic power generation, and in particular to a photovoltaic support and a method for arranging purlins in the photovoltaic support. Background technique [0002] In recent years, the development of photovoltaic power plants has developed rapidly. Among them, the photovoltaic modules need to be fixed on the supporting structure. This supporting structure is the purlin in the photovoltaic support. The purlin in the photovoltaic support is directly connected with the photovoltaic device. It is an indispensable supporting structure. [0003] At present, in the photovoltaic power generation system on the ground, the purlins are generally fixed on the inclined beams, so the inclined beams are used as the supports of the purlins, and the purlins are regarded as continuous beam structures. In order to reduce the internal bending moment of the continuous beams, the The two ends are p...
