Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic equipment, and more specifically, relates to a connection structure suitable for a photovoltaic flexible bracket, a photovoltaic flexible bracket and a photovoltaic power station. Background Art

[0002] Photovoltaic flexible support is a large-span spatial structure technology originated from the fields of construction and bridges. It has the advantages of large span, high clearance, low cost, and environmental friendliness. It can be better combined with photovoltaics and agriculture, photovoltaics and sand control, and photovoltaics and forestry.

[0003] like Figure 1 As shown, the existing flexible bracket generally reduces the cost by setting the cable 13' into a multi-span continuous and uninterrupted form. The core of the flexible bracket is the system controlled by the wind load. The wind load on the flexible bracket is uneven in time and space, that is, the wind load on the cable 13' between two adjacent spans is different at the same time, which will cause the support 11' between the two spans and the connector 15' connecting the cable 13' to the support 11 to be subjected to different forces on both sides. This mode of movement is unique to photovoltaic flexible brackets. If the cable 13' is fixedly connected to the support 11' by the connector 15', the stress on the support 11' and the connector 15' is very large. At this time, the strength requirements of the support 11' and the connector 15' must be very high, which not only increases the investment cost, but also the support 11' and the connector 15' are easily damaged.

[0030] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] The following first describes in detail the connection structure 10 applicable to the photovoltaic flexible bracket according to the embodiment of the utility model in conjunction with the drawings.

[0032] like Figures 2 to 5 As shown, the connection structure 10 applicable to the photovoltaic flexible support according to the embodiment of the utility model includes: a support member 11, a limit member 12, a cable 13 and a damping member 14.

[0033] Specifically, the cable 13 is arranged on the support member 11 extending along the first direction; the limit member 12 is arranged on the support member 11, and the limit member 12 limits the movement of the cable 13 along the first direction. The first end of the damping member 14 is fixedly arranged, and the second end of the damping member 14 is connected to the cable 13 to limit the movable displacement of the cable 13.

[0034] In other words, the connection structure 10 according to the embodiment of the utility model can be used to install a photovoltaic flexible bracket. The connection structure 10 can be mainly composed of a support member 11, a limit member 12, a cable 13 and a damping member 14, wherein the support member 11 is formed as a main structure for supporting the photovoltaic flexible bracket, and the cable 13 can be arranged along the Figure 2 The support member 11 is extended in the left-right direction. When multiple connection structures 10 are used in combination, the photovoltaic panel can be installed on two adjacent cables 13. The support member 11 is provided with a limiter 12, which can cooperate with the cable 13 to limit the moving direction of the cable 13.

[0035] The damping member 14 may be a commonly used damping structure in the art, such as a damper. The damper mentioned in this application should be defined according to the common definition in engineering and structural mechanics, which is a device that provides resistance to movement and consumes movement energy.

[0036] The first end of the damping element 14 can be fixedly set on the ground or other fixed structures, and the second end of the damping element 14 is connected to the cable 13. When the cables 13 between multiple spans are subjected to uneven wind loads, for example, the wind load on the cables 13 at the location where the wind blows will be very large, the cables 13 in this span will pull the cables 13 of the adjacent spans into it, and the damper will be stretched, consuming the energy of the cables 13 and reducing the axial movement of the cables 13.

[0037] Therefore, according to the connection structure 10 of the utility model, by adding the damping member 14, the damping member 14 can provide resistance for the cable. When the cable 13 between multiple spans is subjected to uneven wind loads, wherein the wind load on the cable 13 may be an upward or downward force, or a force in other directions, the damping member 14 can dissipate the energy of the axial movement of the cable 13, reduce the axial movement of the cable 13, and improve the consistency of the sag amount of the cable 13 between different spans. Since the axial movement of the cable 13 is reduced, the deformation of the photovoltaic module fixed on the cable 13 is small, thereby ensuring the power generation of the photovoltaic module, and the stress on the limit member 12 is reduced, thereby improving the stability of the overall structure, higher safety, and better aesthetics.

[0038] According to some embodiments of the present invention, the support member 11 is formed as a columnar structure, the axis of the support member 11 is perpendicular to the first direction, and the cable 13 and the limit member 12 are disposed at the upper end of the support member 11 .

[0039] In other words, the limit member 12 is fixedly connected to the support member 11, and the cable 13 is connected to the limit member 12 to limit the cable 13 from being separated from the support member 11, that is, the vertical and lateral displacements of the cable 13 are limited by the limit member 12, and the limit member 12 does not limit the axial displacement of the cable 13; one end of the damping member 14 is hinged to the cable 13, and the other end can be hinged to the support member 11, and can also be hinged to other devices to dissipate the energy of the axial movement of the cable 13 and reduce the axial movement of the cable 13.

[0040] According to one embodiment of the utility model, Figure 2 and 4 As shown, it also includes a fixing member 15, which is fixedly connected to the cable 13. The first end of the damping member 14 is arranged on the support member 11, and the second end of the damping member 14 is pivotally connected to the fixing member 15 through a connecting shaft. The first end of the damping member 14 is connected to one end of the support member 11, and the damping member 14 is arranged parallel to the cable 13.

[0041] In other words, the first end of the damping member 14 is hinged at the upper end of the support member 11, and the second end of the damping member 14 is pivotally connected to the fixing member 14 through a connecting shaft. The fixing member 14 is fixedly connected to the cable 13, so that the movement direction of the damping member 14 is parallel to the extension direction of the cable 13. When the movement direction is consistent with the axial direction of the cable 13, a good axial damping effect can be obtained, thereby reducing the axial movement of the cable 13.

[0042] According to one embodiment of the utility model, Figure 3 and 5 As shown, it also includes a fixing member 15, which is fixedly connected to the cable 13, a first end of a damping member 14 is arranged on the support member 11, a second end of the damping member 14 is pivotally connected to the fixing member 15 through a connecting shaft, the first end of the damping member 14 is connected to a position away from the end of the support member 11, an extension direction of the damping member 14 intersects with an extension direction of the cable 13 to form an angle, and the angle is an acute angle.

[0043] That is to say, the first end of the damping member 14 is hinged at a position of the support member 11 away from the upper end of the support member 11, and the second end of the damping member 14 is pivotally connected to the fixing member 14 through a connecting shaft, and the fixing member 14 is fixedly connected to the cable 13, so that the movement direction of the damping member 14 forms an angle with the extension direction of the cable 13, and the angle is an acute angle. At this time, the damper direction vector has a component in the axial direction of the cable 13, and the damper direction vector has a component in the vertical or oblique vertical direction in addition to the component in the direction of the cable 13, which can provide a vertical or oblique vertical damping effect while providing an axial damping effect, suppress the vertical or oblique vertical vibration of the cable 13, and reduce the vertical or oblique vertical force of the limiter 12.

[0044] Preferably, the above embodiment also includes a connecting ring 16, which is adjustably arranged on the support member 11 along the axial direction of the support member 11. The first end of the damping member 14 is pivotally connected to the connecting ring 16 through a connecting shaft. During installation, the connecting ring 16 can slide up and down the support member 11. When the required position is determined, the connecting ring 16 is fixed to the support member 11. This design is not only convenient for adjustment and ensures that the damping member 14 can be in the most suitable position, but also convenient for installation and disassembly.

[0045] According to an embodiment of the present invention, the limiting member 12 is provided with a limiting channel extending along the first direction, and the cable 13 is movably arranged in the limiting channel along the first direction.

[0046] The limiting member 12 may also be a clamping member, which is clamped on the supporting member 11 , and the pulling cable 13 passes through the clamping member and is connected to the supporting member 11 through the clamping member.

[0047] According to one embodiment of the utility model, the limiting member 12 includes a mounting portion 121 and a limiting portion 122. The mounting portion 121 is fixedly connected to the upper portion of the support member 11, and the cross-section of the mounting portion 121 is formed in a shape with the opening facing the support member 11; the limiting portion 122 is arranged on the side of the mounting portion 121 facing away from the opening, and a limiting channel is provided in the limiting portion 122.

[0048] The limit member 12 can also be a semi-annular fastener, through which the cable 12 passes. Both ends of the semi-annular fastener are fixedly connected to the support member 11 by bolts. The cable 12 passes through the semi-annular fastener to connect it to the support member. At this time, the cable 12 can move axially in the semi-annular fastener.

The photovoltaic power station according to the embodiment of the present invention includes the photovoltaic flexible bracket according to the above embodiment and a plurality of photovoltaic components.

[0050] Since the connection structure 10 according to the embodiment of the utility model has the above-mentioned technical effects, the photovoltaic flexible bracket and photovoltaic power station according to the embodiment of the utility model also have corresponding technical effects, that is, the axial movement of the cable 13 can be reduced, the stability of the overall structure is improved, and the safety is higher.
