Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic brackets and relates to an inclined cable device at the end of a flexible photovoltaic bracket. Background Art

[0002] The development and utilization of solar energy is a key measure to adjust the energy development strategy and power structure. As various regions pay more attention to energy consumption issues, the photovoltaic power generation industry has received more attention. By building photovoltaic power stations, the energy structure is improved and sustainable economic and environmental development is achieved. In order to achieve the "dual carbon" strategic goal, the new energy photovoltaic power generation industry is gradually moving towards steep slopes, undulating and irregular terrain. Under complex terrain conditions, traditional fixed brackets cannot be used for installation in many cases. Therefore, the cable structure flexible bracket system has become a technical direction for solving the layout of photovoltaic modules in complex environments.

[0003] At present, when the existing cable structure flexible support system is in use, the span of two adjacent cable structure flexible support systems is relatively large, generally 30-150 meters. In order to ensure the overall stability of the cable structure flexible support system, oblique pull rods are often set on the end supports of the cable structure flexible support system.

[0004] However, since the pile position of the end bracket often deviates during construction, and the tie rod is formed in one piece and its length cannot be changed, the installation of the tie rod is more difficult when the pile position construction deviation is large, which increases the time required for installation and affects the overall construction progress. Utility Model Content

[0005] The utility model aims to provide a flexible photovoltaic bracket end inclined cable device, which can adjust the length of the inclined member to avoid affecting the installation of the inclined member when the pile position construction deviation is large.

[0006] In order to achieve the above-mentioned purpose, the specific technical solution of a flexible photovoltaic bracket end inclined cable device provided by the utility model is as follows:

[0007] A flexible photovoltaic bracket end inclined cable device includes at least one end bracket, an end pile is arranged at the lower part of the end bracket, and further includes:

[0008] The inclined brace is arranged between the end bracket and the end pile. The inclined brace includes a basket bolt and two threaded rods. The two threaded rods are respectively arranged at both ends of the basket bolt and form an inclined straight line with the basket bolt. The two ends of the basket bolt are respectively threadedly connected with the two threaded rods, and the ends of the two threaded rods away from the basket bolt are respectively hinged to the end pile and the end bracket through the first hinge.

[0009] The first hinged component includes a connecting plate and a U-shaped plate. The two connecting plates are respectively arranged on the end pile and the end bracket. The U-shaped plate is arranged at the end of the corresponding threaded rod away from the basket bolt. Each connecting plate is located inside the corresponding U-shaped plate and is connected to the corresponding U-shaped plate through a rotating shaft. The rotating shaft is rotatably connected to the connecting plate, and the two ends of the rotating shaft are detachably connected to the inner wall of the U-shaped plate.

[0010] A through hole is provided on the connecting plate, and the rotating shaft passes through the through hole. Both ends of the rotating shaft are respectively connected with the inner wall of the U-shaped plate through threads.

[0011] The included angle between the inclined brace and the end pile in the horizontal direction is 30° to 60°.

[0012] The end pile includes a support seat, a first support column and a second support column. The first support column and the second support column are vertically arranged on the upper part of the support seat and are located close to the two ends of the support seat respectively. The height of the first support column is greater than the height of the second support column. The end bracket is arranged at the upper end of the first support column, and one of the connecting plates is arranged at the upper end of the second support column.

[0013] The lower part of the support seat is provided with anti-pullout columns vertically near the two ends thereof, and the upper ends of the anti-pullout columns are connected to the end piles.

[0014] There are two end brackets and two end piles, the two end piles are arranged side by side, and a reinforcement piece is arranged between the two end piles. The reinforcement piece is an X-shaped structure, and the upper two ends of the reinforcement piece are respectively connected to the two end brackets, and the lower two ends of the reinforcement piece are respectively connected to the two first support columns.

[0015] First, through the cooperation of the end pile, the basket bolt and the two threaded rods, the basket bolt can be rotated to adjust the distance between the two threaded rods, thereby adjusting the length of the diagonal member, avoiding the installation of the diagonal member being affected when the pile position construction deviation is large, reducing the time required for installation, and ensuring the overall construction progress.

[0016] Secondly, by providing the two first hinged members, it is possible to more conveniently connect the two threaded rods to the end piles and the end brackets, respectively, further reducing the time required for installing the inclined stays.

[0017] Third, the device has a simple structure and is easy to implement. It can effectively save building materials, shorten the construction period, and save construction costs, laying a solid foundation for the complex scene application of more efficient and economical cable-structured flexible photovoltaic support systems.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0024] like Figure 1 , 2 As shown, the utility model is a flexible photovoltaic bracket end inclined cable device, including at least one end bracket 4 and an inclined member 6. The lower part of the end bracket 4 is provided with an end pile 1. The inclined member 6 is a rod-shaped structure, and the inclined member 6 is arranged between the end bracket 4 and the end pile 1. The inclined member 6 includes a basket bolt 601 and two threaded rods 602. The two threaded rods 602 are respectively arranged at the two ends of the basket bolt 601 and are in an inclined straight line with the basket bolt 601. The two ends of the basket bolt 601 are respectively threadedly connected with the two threaded rods 602, and the ends of the two threaded rods 602 away from the basket bolt 601 are respectively hinged to the end pile 1 and the end bracket 4 through the first hinge 5. The distance between the two threaded rods 602 is adjusted by rotating the basket bolt 601, thereby adjusting the length of the inclined member 6, avoiding affecting the installation of the inclined member 6 when the pile position construction deviation is large, reducing the time required for installation, and ensuring the overall construction progress.

[0025] like Figure 1 , 2As shown in Figure 3, the first hinge 5 includes a connecting plate 501 and a U-shaped plate 502. The two connecting plates 501 are respectively arranged on the end pile 1 and the end bracket 4, and the two connecting plates 501 are respectively fixedly connected to the end pile 1 and the end bracket 4. The U-shaped plate 502 is arranged at the end of the corresponding threaded rod 602 away from the basket bolt 601. The U-shaped plate 502 is fixedly connected to the end of the corresponding threaded rod 602. Each connecting plate 501 is located inside the corresponding U-shaped plate 502 and is connected to the inner wall of the corresponding U-shaped plate 502 through a rotating shaft. The rotating shaft is rotatably connected to the connecting plate 501, and both ends of the rotating shaft are detachably connected to the inner wall of the U-shaped plate 502. Through the arrangement of the two first hinges 5, it is more convenient to connect the two threaded rods 602 to the end pile 1 and the end bracket 4, respectively, further reducing the time required for the installation of the inclined member.

[0026] like Figure 1 , 2 As shown in FIG. 3 , a through hole is provided on the connecting plate 501, and the rotating shaft passes through the through hole. The rotating shaft can rotate freely in the through hole, and both ends of the rotating shaft are respectively threadedly connected to the inner wall of the U-shaped plate 502, so that the connecting plate 501 and the U-shaped plate 502 can be quickly installed.

[0027] like Figure 1 , 2 As shown, the included angle between the inclined brace 6 and the end pile 1 in the horizontal direction is 30° to 60°. Within this range, the overall stability of the cable structure flexible support system is good.

[0028] like Figure 1 , 2 As shown, the end pile 1 includes a support seat, a first support column and a second support column. The first support column and the second support column are vertically arranged on the upper part of the support seat and are located close to the two ends of the support seat respectively. The lower end of the first support column and the lower end of the second support column are respectively connected to the support seat. The height of the first support column is greater than the height of the second support column. The end bracket 4 is arranged at the upper end of the first support column, and one of the connecting plates 501 is arranged at the upper end of the second support column.

[0029] like Figure 1 , 2 As shown, anti-pullout columns 2 are vertically arranged at the lower part of the support seat near its two ends, and the upper ends of the anti-pullout columns 2 are connected to the end piles 1. The two anti-pullout columns 2 make the end piles 1 more stable.

[0030] like Figure 1 As shown, there are two end brackets 4 and two end piles 1, and the two end piles 1 are arranged side by side. A reinforcement member 8 is arranged between the two end piles 1. The reinforcement member 8 is an X-shaped structure. The upper two ends of the reinforcement member 8 are respectively connected to the two end brackets 4, and the lower two ends of the reinforcement member 8 are respectively connected to the two first support columns, so that the two end brackets 4 arranged side by side are more stable, and the main cable 3 is used to be set on each end bracket 4.

[0031] Working principle: When in use, after the construction of the end pile 1 and the anti-pulling column 2 is completed according to the design, the end bracket 4 can be installed, and the assembled end bracket 4 will be hoisted and stabilized directly above the end pile 1. The operator will support the end bracket 4 to the top steel plate of the end pile 1, accurately adjust the position and fix it for welding. The bottom of the end bracket 4 is fully welded on the steel plate. Before welding, check the center line of the end bracket 4 again to ensure that it coincides with the center of the top steel plate of the end pile 1. Fix the two connecting plates 501 at the bottom of the end bracket 4 and the position of the end pile 1 away from the end bracket 4, so that the two connecting plates 501 are opposite and on an oblique line, and then the U-shaped plates 502 fixed at the ends of the two threaded rods 602 are respectively connected to the two connecting plates 501 through a rotating shaft, and then use the basket bolt 601 to connect the two threaded rods 602, turn the basket bolt 601 to adjust the distance between the two threaded rods 602, and preliminarily tighten the basket bolt 601. In this way, the end bracket 4 and the end pile 1 complete the initial connection. After the prestressed main cable 3 is tensioned, the basket bolt 601 is tightened again to put the diagonal member 6 in a fully stressed state. The tension of the main cable 3 is transmitted to the end pile 1 and the anti-pullout column 2 through the diagonal member 6. At the same time, if two or more end brackets 4 are arranged side by side, the two adjacent end brackets 4 are connected by a reinforcement member 8.

[0032] The utility model provides a flexible photovoltaic bracket end inclined cable device with the following advantages:

[0033] First, through the cooperation of the end pile, the basket bolt and the two threaded rods, the basket bolt can be rotated to adjust the distance between the two threaded rods, thereby adjusting the length of the diagonal member, avoiding the installation of the diagonal member being affected when the pile position construction deviation is large, reducing the time required for installation, and ensuring the overall construction progress.

[0034] Secondly, by providing the two first hinged members, it is possible to more conveniently connect the two threaded rods to the end piles and the end brackets, respectively, further reducing the time required for installing the inclined stays.

[0035] Third, the device has a simple structure and is easy to implement. It can effectively save building materials, shorten the construction period, and save construction costs, laying a solid foundation for the complex scene application of more efficient and economical cable-structured flexible photovoltaic support systems.
