Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic flexible support technology, and specifically relates to a photovoltaic flexible support. Background Technology

[0002] Currently, conventional photovoltaic modules are arranged in a single row facing south, or in a single row facing one direction due to terrain reasons. In order to increase power generation and prevent dust accumulation on the surface of photovoltaic modules, photovoltaic modules are arranged at a certain tilt angle.

[0003] To install and fix photovoltaic (PV) modules, flexible PV mounting systems are equipped with corresponding struts and connectors. Due to the tilt characteristics of PV modules, their front side has better wind resistance than their back side. Therefore, in the design of flexible PV mounting systems, the amount of steel used needs to be increased to improve the wind resistance of the back side of the PV modules. However, traditional flexible PV mounting systems still have insufficient wind resistance in the face of extreme weather and frequent typhoons, especially when the wind blows from the back side of the PV modules to the front side, which can easily cause the PV modules to be blown away or the flexible PV mounting systems to be blown over, resulting in serious damage to the PV power station. In addition, to avoid shading, a certain space needs to be left between adjacent rows of PV modules, which undoubtedly reduces the land utilization rate. Utility Model Content

[0004] In view of the above-mentioned defects of the prior art, the present invention provides a flexible photovoltaic support structure. This flexible photovoltaic support structure can avoid the risk of being blown over or damaged by the wind, can reduce the amount of steel used, and there is no problem of shading between the front row photovoltaic modules and the adjacent rear row photovoltaic modules, which can improve the land utilization rate.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A flexible photovoltaic support structure includes a left support component and a right support component. The left support component includes a left crossbeam arranged horizontally in a front-to-back direction. Multiple left columns are fixed side-by-side at the bottom end of the left crossbeam from front to back. The right support component includes a right crossbeam parallel to the left crossbeam and with its top end flush with the top end of the left crossbeam, and multiple right columns fixed side-by-side at the bottom end of the right crossbeam from front to back. The bottom ends of each left column and each right column are fixed to the ground. Multiple sets of flexible support components are arranged side-by-side between the left and right crossbeams from front to back. Each set of flexible support components includes a front component cable and a rear component cable fixed between the left and right crossbeams and supported by a support assembly. The upper side of the front component cable is used to fix the front row of photovoltaic modules that are inclined forward and downward, and the upper side of the rear component cable is used to fix the rear row of photovoltaic modules that are inclined backward and downward and whose top end is adjacent to the top end of the front row of photovoltaic modules.

[0007] Furthermore, the front component cable and the rear component cable are arranged symmetrically front to back.

[0008] Furthermore, the front component cable includes two front cables arranged side by side, with the left side of each front cable fixedly connected to the left crossbeam and the right side of each front cable fixedly connected to the right crossbeam. The portions of the two front cables located between the left and right crossbeams are arranged horizontally in the left-right direction, and the horizontal height of the front cable is lower than that of the rear cable. The rear component cable includes two rear cables.

[0009] Furthermore, the left portions of both front cables are fixedly connected to the left crossbeam and their left ends are fixed to the ground. The portions of both front cables from their fixed connection to the left crossbeam to their left ends are inclined downwards to the left. The right portions of both front cables are fixedly connected to the right crossbeam and their right ends are fixed to the ground. The portions of both front cables from their fixed connection to the right crossbeam to their right ends are inclined downwards to the right.

[0010] Furthermore, the support assembly includes multiple umbrella-shaped support members with identical structural dimensions arranged side-by-side from left to right. The orthographic projection of each umbrella-shaped support member is arranged along the front-to-back direction and includes two symmetrically arranged diagonal load-bearing struts, two symmetrically arranged horizontal struts, and one vertical strut. The front diagonal load-bearing struts are arranged inclined forward and downward. The tops of the two diagonal load-bearing struts are hinged to the top of the vertical strut. The bottom of the front diagonal load-bearing strut is hinged to the front end of the front horizontal strut, forming a front hinged end. The bottom of the rear diagonal load-bearing strut is hinged to the rear end of the rear horizontal strut, forming a rear hinged end. At the hinged end, the rear end of the front horizontal strut and the front end of the rear horizontal strut are both hinged to the position between the top and bottom ends of the vertical strut; the support assembly also includes a load-bearing cable in a tensioned state, the left end of the load-bearing cable being fixed to the left crossbeam and the right end being fixed to the right crossbeam, and the bottom end of the vertical strut in each umbrella-shaped support member being fixed to the load-bearing cable; the portion of each front cable between the left and right crossbeams is supported and fixed to the front diagonal load-bearing strut of each umbrella-shaped support member, and the portion of each rear cable between the left and right crossbeams is supported and fixed to the rear diagonal load-bearing strut of each umbrella-shaped support member.

[0011] Furthermore, the rear hinged end of each umbrella-shaped support member in the front group of the flexible support components is hinged to the front hinged end of the corresponding umbrella-shaped support member in the adjacent rear group of flexible support components.

[0012] Furthermore, the inclined load-bearing struts, horizontal struts, and vertical struts are all made of tubular profiles. The top and bottom ends of the inclined load-bearing struts are flattened, the front and rear ends of the horizontal struts are flattened, and the top and bottom ends of the vertical struts are flattened. The load-bearing cables are sequentially threaded through and fixed to the through holes at the bottom ends of the vertical struts in each umbrella-shaped support member from left to right.

[0013] Furthermore, the vertical strut is fixed with hinge mounting seats at the positions where it is hinged to the front and rear horizontal struts, and the rear end of the front horizontal strut and the front end of the rear horizontal strut are respectively hinged to one of the hinge mounting seats of the vertical strut.

[0014] Furthermore, the structural dimensions of each group of flexible support components are the same, and the front-to-back horizontal distance between the front group of flexible support components and the adjacent rear group of flexible support components is equal.

[0015] Furthermore, the left support component and the right support component are arranged symmetrically from left to right.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] The flexible photovoltaic support system of this invention includes a front component cable and a rear component cable fixed between the left and right crossbeams and supported by a support assembly. The upper side of the front component cable is used to fix the front row of photovoltaic modules that are inclined downwards and forwards, while the upper side of the rear component cable is used to fix the rear row of photovoltaic modules that are inclined downwards and backwards and whose tops are adjacent to the tops of the front row of photovoltaic modules. This arrangement of the front component cable, rear component cable, and support assembly ensures that the front row of photovoltaic modules fixed to the upper side of the front component cable and the rear row of photovoltaic modules fixed to the upper side of the rear component cable have opposite inclination directions, and that the tops of the front row of photovoltaic modules are adjacent to the tops of the adjacent rear row of photovoltaic modules. When the wind blows from the back side to the front side of the front row of photovoltaic modules, the wind force directly acts on the front of the rear row of photovoltaic modules adjacent to the front row, and does not directly act on the back side of the front row of photovoltaic modules. The modules are not easily blown away by the wind. Similarly, when the wind blows from the back side of the rear row photovoltaic modules to the front side, the wind force acts directly on the front of the front row photovoltaic modules adjacent to the rear row photovoltaic modules, and does not directly act on the back of the rear row photovoltaic modules. The rear row photovoltaic modules are not easily blown away by the wind. Thus, the photovoltaic flexible support can avoid the risk of being blown over or damaged by the wind. There is no need to specifically improve the wind resistance of the back of the front row photovoltaic modules and the back of the adjacent rear row photovoltaic modules, thereby reducing the amount of steel used in the flexible support components. Moreover, since the front row photovoltaic modules fixed to the upper side of the front module cable and the rear row photovoltaic modules fixed to the upper side of the rear module cable have opposite tilt directions, there is no problem of shading between the front row photovoltaic modules and the adjacent rear row photovoltaic modules. There is no need to leave a certain space between the front row photovoltaic modules and the adjacent rear row photovoltaic modules. In this utility model, the top of the front row photovoltaic modules is adjacent to the top of the adjacent rear row photovoltaic modules, which can improve the land utilization rate.

[0018] In this invention, the support assembly includes multiple umbrella-shaped support members with identical structural dimensions arranged side-by-side from left to right. The orthographic projection of each umbrella-shaped support member is arranged along the front-to-back direction and includes two symmetrically arranged diagonal load-bearing struts, two symmetrically arranged horizontal struts, and one vertical strut. The front diagonal load-bearing struts are arranged inclined forward and downward. The tops of the two diagonal load-bearing struts are hinged to the top of the vertical strut. The bottom of the front diagonal load-bearing strut is hinged to the front end of the front horizontal strut, forming a front hinged end. The bottom of the rear diagonal load-bearing strut is hinged to the rear end of the rear horizontal strut, forming a... At the rear hinge end, the rear end of the front horizontal strut and the front end of the rear horizontal strut are both hinged to the position between the top and bottom ends of the vertical strut; the support assembly also includes a load-bearing cable in a tensioned state, with the left end of the load-bearing cable fixed to the left crossbeam and the right end fixed to the right crossbeam, and the bottom end of the vertical strut in each umbrella-shaped support is fixed to the load-bearing cable; the portion of each front cable between the left and right crossbeams supports and is fixed to the front diagonal load-bearing strut of each umbrella-shaped support, and the portion of each rear cable between the left and right crossbeams supports and is fixed to the rear diagonal load-bearing strut of each umbrella-shaped support. This arrangement of multiple umbrella-shaped supports and tensioned load-bearing cables reduces the deflection of the two front cables in the front module and the two rear cables in the rear module. It also effectively transmits the weight of the front-row photovoltaic modules and adjacent rear-row modules, as well as lateral wind loads. Furthermore, the symmetrical design of the umbrella-shaped supports allows for handling wind loads from opposite directions. By adjusting the length of the diagonal load-bearing struts and / or horizontal struts within each umbrella-shaped support, the angle between the diagonal and horizontal struts can be controlled, thereby adjusting the tilt angle of the front-row and adjacent rear-row photovoltaic modules. The front diagonal load-bearing struts support and secure the two front cables, while the rear diagonal struts... The load-bearing struts are used to support and fix the two rear cables to facilitate the installation of the front row photovoltaic modules and the adjacent rear row photovoltaic modules. The horizontal struts act as a lateral connection for the entire flexible support component, which can reduce the swaying of the diagonal load-bearing struts on both sides in strong winds. This, in turn, can reduce the swaying of the two front cables on the front diagonal load-bearing struts and the two rear cables on the rear diagonal load-bearing struts. The vertical struts are used to connect the diagonal load-bearing struts, the horizontal struts, and the load-bearing cables. The load-bearing cables, which are under tension, provide an upward force to the vertical struts of each umbrella-shaped support, thereby indirectly counteracting the weight of the front row photovoltaic modules and the adjacent rear row photovoltaic modules.

[0026] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. These embodiments are only used to illustrate this utility model and are not intended to limit it.

[0027] In the description of this utility model, it should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0030] like Figure 1 and Figure 2 As shown, a flexible photovoltaic support structure includes a left support component and a right support component. The left support component includes a left crossbeam 101 arranged horizontally along the front-to-back direction. Multiple left columns 102 are fixed side-by-side from front to back at the bottom end of the left crossbeam 101. The right support component includes a right crossbeam 201 parallel to the left crossbeam 101 and with its top end flush with the top end of the left crossbeam 101, and multiple right columns 202 fixed side-by-side from front to back at the bottom end of the right crossbeam 201. The bottom ends of each left column 102 and each right column 202 are fixed... On the ground, multiple sets of flexible support components are arranged side-by-side from front to back between the left crossbeam 101 and the right crossbeam 201. Each set of flexible support components includes a front component cable and a rear component cable fixed between the left crossbeam 101 and the right crossbeam 201 and supported by a support assembly. The upper side of the front component cable is used to fix the front row of photovoltaic modules 301 that are inclined forward and downward, and the upper side of the rear component cable is used to fix the rear row of photovoltaic modules 302 that are inclined backward and downward and whose tops are adjacent to the tops of the front row of photovoltaic modules 301. The left column 102 and the right column 202 can be concrete cast-in-place piles, and the left crossbeam 101 and the right crossbeam 201 are steel structural profiles.

[0031] In this way, the arrangement of the front component cable, the rear component cable, and the support components for supporting the front and rear component cables in each set of flexible support components ensures that the tilt directions of the front row photovoltaic modules 301 fixed to the upper side of the front component cable and the rear row photovoltaic modules 302 fixed to the upper side of the rear component cable are opposite. This also ensures that the top of the front row photovoltaic module 301 is close to the top of the adjacent rear row photovoltaic module 302. When the wind blows from the back side of the front row photovoltaic module 301 to the front side, the wind force acts directly on the front of the adjacent rear row photovoltaic module 302, and does not directly act on the back side of the front row photovoltaic module 301. Therefore, the front row photovoltaic module 301 is less likely to be blown away by the wind. Similarly, when the wind blows from the back side of the rear row photovoltaic module 302 to the front side, the wind force acts directly on the front of the adjacent front row photovoltaic module 301. Since the wind force does not directly act on the back of the rear row photovoltaic modules 302, the rear row photovoltaic modules 302 are not easily blown away by the wind. Therefore, the flexible photovoltaic support can avoid the risk of being blown over or damaged by the wind. There is no need to specifically improve the wind resistance of the back of the front row photovoltaic modules 301 and the back of the adjacent rear row photovoltaic modules 302, thereby reducing the amount of steel used in the flexible support components. Moreover, since the tilt direction between the front row photovoltaic modules 301 fixed to the upper side of the front component cable and the rear row photovoltaic modules 302 fixed to the upper side of the rear component cable is opposite, there is no problem of shading between the front row photovoltaic modules 301 and the adjacent rear row photovoltaic modules 302. There is no need to leave a certain space between the front row photovoltaic modules 301 and the adjacent rear row photovoltaic modules 302. In this utility model, the top of the front row photovoltaic modules 301 is adjacent to the top of the adjacent rear row photovoltaic modules 302, which can improve the land utilization rate.

[0032] In one embodiment,

[0033] The front and rear component cables are arranged symmetrically. For example, Figure 2 and Figure 3 As shown, the front component cable includes two front cables 401 arranged side by side. The left side of each front cable 401 is fixedly connected to the left crossbeam 101 and the right side is fixedly connected to the right crossbeam 201. The portion of the two front cables 401 between the left crossbeam 101 and the right crossbeam 201 is arranged horizontally in the left-right direction, and the horizontal height of the front cable 401 is lower than that of the rear cable 401. The rear component cable includes two rear cables 402.

[0034] In a preferred embodiment,

[0035] The left sides of both front cables 401 are fixedly connected to the left crossbeam 101, and their left ends are fixed to the ground. The portions of both front cables 401 from their fixed connection to the left crossbeam 101 to their left ends slope downwards to the left. Figures 1-3Both front cables 401 are fixedly connected to the right crossbeam 201 on their right sides, and their right ends are fixed to the ground. The portions of both front cables 401 from their fixed connection to the right crossbeam 201 to their right ends slope downwards to the right. Figure 1 This improves the stability of the two front cables 401.

[0036] In another preferred embodiment,

[0037] The support assembly includes multiple umbrella-shaped support members 5, all with identical structural dimensions, arranged side by side from left to right, see... Figure 2 and Figure 3 Each umbrella-shaped support 5 has its orthographic projection arranged along the front-to-back direction and includes two symmetrically arranged diagonal load-bearing struts 501, two symmetrically arranged horizontal struts 502, and one vertical strut 503. The front diagonal load-bearing struts 501 are arranged inclined forward and downward. The tops of the two diagonal load-bearing struts 501 are hinged to the tops of the vertical strut 503. The bottom of the front diagonal load-bearing strut 501 is hinged to the front end of the front horizontal strut 502 to form a front hinge end. The bottom of the rear diagonal load-bearing strut 501 is hinged to the rear end of the rear horizontal strut 502 to form a rear hinge end. The rear end of the front horizontal strut 502 and the front end of the rear horizontal strut 502 are both hinged at a position between the top and bottom of the vertical strut 503. See [link to relevant documentation]. Figures 2-6 The support assembly also includes a tensioned load-bearing cable 6, with its left end fixed to the left crossbeam 101 and its right end fixed to the right crossbeam 201. The bottom end of the vertical strut 503 in each umbrella-shaped support member 5 is fixed to the load-bearing cable 6. (See attached image.) Figure 2 and Figure 3 The portion of each front cable 401 located between the left crossbeam 101 and the right crossbeam 201 is supported and fixed to the front diagonal load-bearing strut 501 of each umbrella-shaped support member 5. Similarly, the portion of each rear cable 402 located between the left crossbeam 101 and the right crossbeam 201 is supported and fixed to the rear diagonal load-bearing strut 501 of each umbrella-shaped support member 5. (See...) Figure 2 and Figure 3 .

[0038] By using multiple umbrella-shaped support members 5 and tensioned load-bearing cables 6, the deflection of the two front tension cables 401 in the front component cable and the deflection of the two rear tension cables 402 in the rear component cable can be reduced. This also allows for the transfer of the weight of the front row photovoltaic modules 301 and the adjacent rear row photovoltaic modules 302, as well as lateral wind loads. Furthermore, due to the overall symmetrical design of the umbrella-shaped support members 5, it can handle wind loads from opposite directions. In each umbrella-shaped support member 5, by adjusting the length of the diagonal load-bearing strut 501 and / or the horizontal strut 502, the angle between the diagonal load-bearing strut 501 and the horizontal strut 502 can be controlled, thereby adjusting the tilt angle of the front row photovoltaic modules 301 and the adjacent rear row photovoltaic modules 302. The front diagonal load-bearing strut 501 supports and fixes the two front tension cables 401, and the rear diagonal load-bearing strut 501 supports and fixes the two rear tension cables 402, facilitating the movement of the front row photovoltaic modules. The installation of 301 and the adjacent rear photovoltaic modules 302 includes a horizontal support rod 502 that acts as a lateral connection for the entire flexible support component. This reduces the swaying of the front and rear inclined support rods 501 in strong winds, thereby reducing the swaying of the two front tension cables 401 on the front inclined support rod 501 and the two rear tension cables 402 on the rear inclined support rod 501. The vertical support rod 503 connects the inclined support rods 501, the horizontal support rod 502, and the load-bearing cable 6. The load-bearing cable 6, under tension, provides an upward force to the vertical support rods 503 of each umbrella-shaped support member 5, thereby indirectly counteracting the weight of the front photovoltaic modules 301 and the adjacent rear photovoltaic modules 302. The load-bearing cable 6 is fixedly connected to the bottom end of the vertical support rod 503 in each umbrella-shaped support member 5, enabling the entire flexible support component to be flexibly fixed in the longitudinal direction.

[0039] Preferably, the rear hinged end of each umbrella-shaped support member 5 in the front set of flexible support components is hinged to the front hinged end of the corresponding umbrella-shaped support member 5 in the adjacent rear set of flexible support components, see... Figure 2 and Figure 3 .

[0040] This enables lateral connections between the various flexible support components in the entire photovoltaic flexible support system, and the hinged connection method ensures that adjacent flexible support components have a certain degree of freedom.

[0041] Preferably, the diagonal support strut 501, the horizontal support strut 502, and the vertical support strut 503 are all made of tubular profiles. The top and bottom ends of the diagonal support strut 501 are flattened, the front and rear ends of the horizontal support strut 502 are flattened, and the top and bottom ends of the vertical support strut 503 are flattened. Figures 4-6 The load-bearing cables 6 are sequentially threaded through and fixed to the through holes 50302 at the bottom of the vertical support rods 503 in each umbrella-shaped support member 5 from left to right.

[0042] The flattening process at the ends of the inclined load-bearing strut 501, horizontal strut 502, and vertical strut 503 can improve the local stress conditions of these struts.

[0043] Preferably, the vertical support rod 503 is fixed with hinge mounting seats 50301 at positions where it hinges to the front and rear horizontal support rods 502. The rear end of the front horizontal support rod 502 and the front end of the rear horizontal support rod 502 are respectively hinged to one of the hinge mounting seats 50301 of the vertical support rod 503. Figures 4-6 .

[0044] The hinged mounting base 50301 facilitates the hinged connection between the two horizontal struts 502 and the vertical strut 503.

[0045] In one embodiment, the structural dimensions of each group of flexible support components are the same, and the front-to-back horizontal distance between the front group of flexible support components and the adjacent rear group of flexible support components is equal.

[0046] In one embodiment, the left support component and the right support component are arranged symmetrically.

[0047] The installation method of the photovoltaic flexible support in this utility model is as follows: the entire photovoltaic flexible support is raised to the designed height by the left support component and the right support component. The front component cable and the rear component cable of each flexible support component are installed between the left crossbeam 101 and the right crossbeam 201. Due to the material of the two front tension cables 401 in the front component cable and the two rear tension cables 402 in the rear component cable, as well as the large span of the entire flexible support component, an umbrella-shaped support 5 is installed at intervals. Combined with the load-bearing cable 6 in a pre-tightened state, the tension of the two front tension cables 401 in the front component cable and the two rear tension cables 402 in the rear component cable is realized, so that the deflection of the two front tension cables 401 in the front component cable and the deflection of the two rear tension cables 402 in the rear component cable are controlled within a reasonable range.

[0048] In this invention, for each umbrella-shaped support member 5, the factory-customized inclined load-bearing struts 501, horizontal struts 502 and vertical struts 503 are quickly assembled using fasteners to complete the assembly of the umbrella-shaped support member 5. This saves on-site installation time and reduces on-site construction difficulty.

[0049] Each flexible support component in this invention is a five-cable umbrella-shaped flexible support. Specifically, each flexible support component includes two front tension cables 401, two rear tension cables 402, and one load-bearing cable 6. Due to the overall symmetrical design of the umbrella-shaped support component 5, each flexible support component in this photovoltaic flexible support is not only subjected to symmetrical and stable forces, but also increases the reliability of this photovoltaic flexible support in the event of extreme weather and frequent typhoons. It can avoid the risk of being blown over or damaged by the wind, and can reduce the amount of steel used in each flexible support component. Since the front row photovoltaic modules 301 and the adjacent rear row photovoltaic modules 302 are installed back to back, there is no problem of mutual shading when the tilt angle is small. Compared with the traditional single row of photovoltaic modules arranged in one direction, a certain space needs to be left between the two adjacent rows of photovoltaic modules to avoid shading. The photovoltaic flexible support of this invention can improve land utilization.

[0050] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
