Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic support structures, in particular to a support column used for a flexible photovoltaic system. Background Art

[0002] With the rapid development of my country's economy and science and technology, the drawbacks of traditional power generation methods have become increasingly prominent, and photovoltaic power generation has come into being. Under the background of the "dual carbon" strategy, the photovoltaic energy industry has become increasingly popular due to its green, clean and sustainable development characteristics. In recent years, the number of photovoltaic power generation projects has increased year by year, and its investment value has become increasingly prominent. Traditional photovoltaic brackets are generally rigid structures, while modern photovoltaic brackets are mainly flexible structures. At present, traditional photovoltaic brackets are mostly built in deserts, Gobi and other places with large areas and high flatness. It is difficult to build in areas with poor terrain conditions, so construction and development are limited by land resources.

[0003] The introduction of flexible photovoltaic brackets has greatly overcome the constraints of complex terrain and can adapt to complex terrain conditions such as mountains, barren slopes, pools, fish ponds and woodlands. The characteristics of small footprint and strong site adaptability can also make photovoltaic brackets a bridge connecting the photovoltaic industry with agriculture, forestry, fishery and other industries. It is an effective way to improve the utilization rate of solar energy per unit area and promote the integration of multiple industries, and has extremely high economic value.

[0004] The flexible photovoltaic support structure system is generally divided into two parts: the flexible system and the support system. The flexible system consists of prestressed suspension cables, stabilizing cables, component fixing fixtures, photovoltaic components, etc.; the support system consists of foundations, steel columns, support systems, etc. It has the advantages that traditional supports lack, such as simple structure, less material use, light weight, and short construction period; however, in the support system, the support column is more important, and the function of the support rod is to support and fix the cable (such as the zipper and wind cable of flexible photovoltaics). The traditional way of connecting the support rod and the cable is to directly fix the cable to the support rod, which will cause the support rod to have a large tension and stress, and the wind resistance performance is basically concentrated on the strength and installation stability of the support rod.

DETAILED DESCRIPTION

[0023] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0024] In this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprises", or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article, or apparatus.

[0025] As described in the background technology, the flexible photovoltaic support structure system is generally divided into two parts: the flexible system and the support system. The flexible system is composed of prestressed suspension cables, stabilizing cables, component fixing fixtures, photovoltaic components, etc.; the support system is composed of foundations, steel columns, support systems, etc. It has the advantages that traditional supports lack, such as simple structure, less material use, light weight, and short construction period; however, in the support system, the support column is more important, and the function of the support rod is to support and fix the cable (such as the zipper and wind cable of flexible photovoltaics). The traditional way of connecting the support rod and the cable is to directly fix the cable to the support rod, which will cause the support rod to have a large tension and stress, and the wind resistance performance is basically concentrated on the strength and installation stability of the support rod.

[0026] Based on the above reasons, this embodiment provides a support column for a flexible photovoltaic system, such as Figure 1 and Figure 2As shown, the support column includes a support rod 101 and a base 102, and the support rod 101 is fixedly mounted on the base 102;

[0027] A plurality of support guides 103 with different heights for supporting and changing the direction of the cable 200 are installed on the support rod 101 . The cable is fixedly connected to the base 102 after passing through the support guides 103 .

[0028] In the above technical features, the force point of the cable can be transferred to the base through the support guide part, which changes the force direction of the support rod, reduces the force on the support rod, thereby improving the stability of the support rod, and then improving the wind resistance of the entire flexible photovoltaic system; and several support guide parts with different heights are arranged on the support rod, which facilitates the arrangement of cables of different heights.

[0029] In order to better guide the cable, Figure 2 As shown, the support guide part is a roller rotatably mounted on the support rod. Further, a plurality of mounting slots 104 with different heights are provided on the support rod, and the roller is rotatably mounted on the mounting slots 104 via an axis.

[0030] The above-mentioned technical features can better guide the cables, and the sliding friction between the cables and the support rods can be converted into rolling friction by means of rotating rollers, thereby reducing the friction between the cables and the support rods, improving the stability of the cables and protecting the cables, and making it easier for workers to arrange the cables.

[0031] In order to improve the strength and wind resistance of the support pole, in one embodiment, a connecting frame 105 fixed to the support pole 102 is provided on the outer side of the installation groove, and a connecting plate 106 is provided between adjacent connecting frames 105. The wind rope 300 of the support pole 102 can be connected to the side of the connecting frame 105 or the side of the connecting plate.

[0032] In the above technical features, the strength of the support rod can be improved by the connecting frame and the connecting plate (because the strength of the support rod will be reduced after the grooves are opened). At the same time, the connecting frame can protect the roller and the cable when they cooperate. The connecting plate can not only improve the strength of the support rod, but also facilitate the connection of the wind cable, thereby improving the wind resistance of the support rod. In order to facilitate the connection of the wind cable, a connecting ear is provided on the connecting plate 106.

[0033] In order to realize the convenient installation of the support column and change the stress condition of the support column, such as Figure 3 and Figure 4As shown, in one embodiment, a support rod connection portion 107 and / or a cable connection portion 108 is provided on the base 102, and the cable connection portion is located on the outside of the support rod connection portion, and the support rod is fixedly installed on the support rod connection portion, and after the cable passes through the support guide portion, the end of the cable is fixedly connected to the cable connection portion; the support rod connection portion has a mounting inclined surface 1081 for tilting the support rod.

[0034] The base and the support rod connection part and the cable connection part above the base described in the above technical features can be prefabricated to make it more convenient to install on site; the support rod connection part and the cable connection part are bosses, which facilitate the installation of the support column through the support rod connection part, and a slope is provided on the support rod connection part, which can realize the inclined installation of the support column and change the stress condition of the support rod (because the traditional zipper is directly connected to the support rod, which exerts a tensile force on the support rod, and this tensile force can only be overcome by the strength of the support rod or by adding a wind rope, while after the roller guide, the connection point of the zipper is set on the base or other foundation, and the stress on the support rod is also changed. When the support rod is installed at an angle, the bending force of the tensile force on the support rod can be reduced or eliminated, so that the support rod is more subjected to pressure and the reaction force given by the base.), and the cable connection can be facilitated by the cable connection part.

[0035] like Figure 3 and 4 As shown, when the utility model is used, according to the requirements of the site conditions, the base type is selected (the base type includes a type with only a cable connection part, a type with only a support rod connection part, and a type with both a support rod connection part and a cable connection part), and then the base is pre-buried in the site; the support rod is directly installed on the base or installed on the support rod connection part of the base (when the support rod is subjected to a large tensile force, the support rod is selected to be installed obliquely through the support rod connection), and the cable of the flexible photovoltaic system is connected to the base or the cable connection part of the base after passing through the support guide part (if two or more cables are installed on the support rod, in order to ensure the parallel arrangement of the cables, the cables are fixed through the cable connection part). In order to improve the wind resistance and stability of the support rods, adjacent support rods are connected by connecting cables 400.

[0036] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
