Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic brackets, and particularly relates to a steel strand support component for a flexible photovoltaic bracket on a mountain. Background Art

[0002] Photovoltaic power generation is a technology that directly converts light energy into electrical energy by using the photovoltaic effect at the semiconductor interface, and mainly consists of three major parts: solar panels (modules), brackets, and inverters. Solar energy is a renewable energy source that is inexhaustible for humans and plays an important role in the long-term energy strategy. Since most parts of China are located in the mid-latitudes, the solar altitude angle changes greatly between summer and winter, and mountainous areas are widely distributed. At present, fixed brackets are mostly used in photovoltaic power generation systems in complex terrains such as mountains, resulting in low power generation and difficulty in meeting the system's total installed capacity standard.

[0003] The use of flexible photovoltaic brackets on mountains can effectively reduce the total system investment and increase the total installed capacity of the system. However, in the past, when using flexible photovoltaic brackets, it was found that there were problems such as limited terrain adaptability and overly simple design of the steel strand support components. For example, stress concentration occurs at the corner positions of the steel strand, which easily damages the steel strand, thus having an adverse impact on the reliability and service life of the steel strand of the flexible photovoltaic bracket on the mountain. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the technical problems existing in the background art. For this reason, a steel strand support component for a flexible photovoltaic bracket on a mountain is provided.

[0005] In order to achieve the above purpose, the technical solutions adopted by the utility model are as follows:

[0006] A steel strand support component for a flexible photovoltaic bracket on a mountain, comprising an arc-shaped support plate, a steel strand, a support bottom beam, and a U-shaped bolt.

[0007] The arc-shaped support plate is fixedly installed on the support bottom beam through a longitudinal plate.

[0008] The steel strand passes through the U-shaped bolt, and both ends of the steel strand are respectively connected to the previous-span flexible bracket and the next-span flexible bracket.

[0009] The U-shaped bolt is installed on the arc-shaped support plate and locked by a nut.

[0010] The following is a further limited technical solution of the utility model. The arc-shaped support plate is set as an overall circular arc-shaped support plate.

[0011] The following is a further limited technical solution of the utility model. The arc-shaped support plate is set as a support plate in which circular arcs and straight lines are alternately connected.

[0012] The following are the further defined technical solutions of the present utility model. Two sets of U-bolt connection holes are opened on the arc-shaped support plate, and the two sets of U-bolt connection holes are respectively arranged at the middle-lower position and the middle-upper position of the arc-shaped support plate.

[0013] Compared with the prior art, the present utility model has the following technical effects:

[0014] The present utility model adopts an arc-shaped support plate, which improves the adaptability of the flexible support steel strand to the complex terrain of large-slope mountains, increases the contact area of the steel strand at the support position, avoids stress concentration of the steel strand at the bend, effectively improves the service life and reliability of the steel strand, and improves the installation portability of the steel strand; furthermore, by adopting U-bolts, the steel strand and the arc-shaped support plate can be effectively and tightly connected, preventing the flexible support from loosening during operation and improving the overall reliability of the flexible support.

[0019] In order to make the above-mentioned objects, features, and advantages of the present utility model more obvious and understandable, the following will give a detailed description of the specific embodiments of the present utility model in conjunction with the drawings. Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein. Those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0020] As Figure 1 shown, this embodiment provides a steel strand support component for a flexible mountain photovoltaic bracket, and the main components include: an arc-shaped support plate 1, a steel strand 2, a support bottom beam 3, a U-bolt 4, etc.

[0021] The arc-shaped support plate 1 is fixedly installed on the support bottom beam 3 through the longitudinal plate. Among them, the arc-shaped support plate 1 and the longitudinal plate are welded, and the longitudinal plate and the support bottom beam 3 are welded.

[0022] The steel strand 2 passes through the U-bolt 4, and the two ends of the steel strand 2 are respectively connected with the flexible support 6 of the previous span and the flexible support 5 of the next span.

[0023] The U-bolt 4 is installed on the arc-shaped support plate 1 and locked by a nut.

[0024] In the present utility model, the structure of the arc-shaped support plate 1 has two implementation manners: the arc-shaped support plate 1 is set as an integral circular arc support plate, or the arc-shaped support plate 1 is set as a support plate in which circular arcs and straight lines are alternately connected, so as to ensure that the steel strand 2 can transition from the flexible support 6 of the previous span to the flexible support 5 of the next span with a larger turning radius, increasing the contact area of the steel strand 2 at the support position, avoiding stress concentration of the steel strand 2 at the bend, and effectively improving the service life and reliability of the steel strand 2 in the flexible support.

[0025] In this embodiment, as Figure 1 shown, the arc-shaped support plate 1 is selected as a support plate in which circular arcs and straight lines are alternately connected.

[0026] Two groups of U-bolt connection holes are formed on the arc-shaped support plate 1, and the two groups of U-bolt connection holes are respectively arranged at the middle and lower positions and the middle and upper positions of the arc-shaped support plate 1. When installing the U-bolt 4, the appropriate connection hole position can be selected according to the contact situation between the steel strand 2 and the arc-shaped support plate 1. The U-bolt 4 can lock the steel strand 2, effectively connecting the steel strand 2 and the arc-shaped support plate 1 tightly, preventing the flexible support from loosening during operation, and improving the overall reliability of the flexible support.

[0027] In this embodiment, as Figure 1 shown, the U-bolt 4 is installed at the middle and lower position of the arc-shaped support plate 1.

[0028] The above are only the preferred embodiments of the present utility model, and do not impose any form of limitation on the present utility model.
