Description

Technical Field

[0001] This utility model relates to the field of photovoltaic flexible support technology, and in particular to a wind-resistant device for a three-cable flexible photovoltaic support. Background Technology

[0002] Flexible photovoltaic systems use steel strands as the main load-bearing cables (main cables). The main cables are then fixed by end supports composed of steel beams, side anchors, etc. Since the span of the main cables is usually large and photovoltaic panels are connected to the main cables through connectors, the overall wind resistance is relatively large. In windy weather, there is a risk of large swaying and damage to the system. Therefore, a wind-resistant system is usually installed in the span of the photovoltaic system. The wind-resistant system is usually set below the main cables, with one end fixedly connected to the ground and the other end fixedly connected to at least two main cables to improve the integrity of the photovoltaic system and enhance its wind resistance performance.

[0003] As attached Figure 1 As shown, the current wind-resistant system (wind-resistant device) is mainly assembled into a triangular wind-resistant frame by three poles. The three nodes of the wind-resistant frame are equipped with connecting structures, which are connected to the main cable. The wind-resistant frames between rows are then connected by one or two inter-row connecting rods.

[0004] The technical problems of the above-mentioned existing technology are as follows: the length of the connecting rods between the rows of wind-resistant frames is fixed and cannot be extended or adjusted, which makes it impossible to adjust the spacing between the rows of wind-resistant frames. Since the actual spacing between the rows changes with the slope of the mountain, the connection length between the rows needs to be adjusted according to the actual situation. Therefore, it is necessary to design a wind-resistant device that can adjust the distance between the rows. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose a wind-resistant device for a three-cable flexible photovoltaic support, so as to solve the technical problem that the spacing between rows of existing flexible photovoltaic support wind-resistant devices is not adjustable.

[0006] To achieve the above objectives, this utility model provides a wind-resistant device for a three-cable flexible photovoltaic support, comprising:

[0007] Wind-resistant frame;

[0008] Three connecting structures are provided on the wind-resistant frame, and the connecting structures are respectively used to fix the three main cables to the wind-resistant frame;

[0009] A row connecting rod A is provided between two adjacent wind-resistant frames to connect them. The row connecting rod A has multiple waist-shaped holes on its surface along its length direction. Correspondingly, a fourth positioning hole adapted to the waist-shaped holes is provided on the wind-resistant frame.

[0010] The positioning component is used to pass through and connect the waist-shaped hole and the corresponding fourth positioning hole so that the row connecting rod A is fixedly connected to the wind-resistant frame. In use, the arrangement spacing between adjacent rows of the wind-resistant frame can be adjusted by selecting different waist-shaped holes on the row connecting rod A to connect and fix with the fourth positioning hole.

[0011] As a preferred embodiment of this utility model, the wind-resistant frame includes:

[0012] The component support rod is linear;

[0013] The wind-resistant curved rod with a V-shaped structure, together with the component support rod, forms a triangular wind-resistant frame, and the three connecting structures are respectively set at the three corners of the wind-resistant frame.

[0014] As a preferred technical solution of this utility model, the connection structure includes a first U-bolt and a first U-bolt nut. The upper end of the component support rod is provided with at least two second positioning holes. The rod body of the first U-bolt passes through the second positioning holes and is fixedly connected to the first U-bolt nut. An annular limiting space is formed between the first U-bolt and the component support rod for the main cable to pass through.

[0015] As a preferred technical solution of this utility model, at least one first mounting hole is provided through the upper ends of both sides of the wind-resistant curved rod, and a third positioning hole corresponding to the first mounting hole is provided through the upper end of the component support rod. The wind-resistant device also includes a second U-bolt and a second U-bolt nut. The rod body of the second U-bolt passes through the third positioning hole and the first mounting hole in sequence and is connected to the second U-bolt nut.

[0016] As a preferred embodiment of this utility model, the positioning element is a fastening bolt disposed in the fourth positioning hole, and the shank of the fastening bolt passes through the fourth positioning hole and the waist-shaped hole in sequence and is connected to the fastening nut.

[0017] As a preferred embodiment of this utility model, the component support rod has a square hole on the side opposite to the fourth positioning hole.

[0018] As a preferred embodiment of this utility model, the wind-resistant device further includes a row-to-row connecting rod B, which is the same as the row-to-row connecting rod A. The row-to-row connecting rod B is fixed to the other end of the wind-resistant frame relative to the row-to-row connecting rod A by a positioning member.

[0019] As a preferred technical solution of this utility model, one of the two adjacent wind-resistant frames is provided with two fastening bolts. The two fastening bolts are separated from each other and form a gap. The gap is used to clamp one end of the row connecting rod A to restrict its rotation.

[0020] As a preferred embodiment of this utility model, the wind-resistant device further includes a wind-resistant steel wire rope and a wiring structure for fixing the wind-resistant steel wire rope to the wind-resistant frame.

[0021] As a preferred technical solution of this utility model, the wiring structure includes a third U-bolt and a third U-bolt nut. The shank of the third U-bolt passes through the second mounting hole and / or the first positioning hole opened on the surface of the wind-resistant frame and is fixedly connected to the third U-bolt nut. The third U-bolt and the surface of the wind-resistant frame form a positioning space for positioning the wind-resistant steel wire rope.

[0022] The beneficial effects of this utility model are as follows: By opening multiple waist-shaped holes on the inter-row connecting rod A, this utility model can connect and fix different waist-shaped holes on the inter-row connecting rod A with the fourth positioning hole of the wind-resistant frame, thereby adjusting the arrangement spacing between adjacent wind-resistant frame rows. This allows the connection length between wind-resistant frame rows to be adjusted according to the actual situation. In addition, the waist-shaped holes allow for position adjustment within a certain range during installation and under stress, which is crucial for adapting to the deformation of the cable structure, facilitating installation and adjustment, and releasing some of the stress caused by wind load.

[0036] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0037] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains. The terms "first," "second," and similar terms used in this utility model do not indicate any order, quantity, or importance, but are merely used to distinguish different components.

Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0038] like Figure 2 and Figure 3As shown, a wind-resistant device for a three-cable flexible photovoltaic support includes: a wind-resistant frame; three connecting structures disposed on the wind-resistant frame, each connecting structure being used to fix three main cables 2 to the wind-resistant frame; a row-to-row connecting rod A5 disposed between two adjacent wind-resistant frames for connecting the two, the row-to-row connecting rod A5 having multiple waist-shaped holes 5.1 opened on its surface along its length direction, correspondingly, a fourth positioning hole 3.5 adapted to the waist-shaped holes 5.1 is opened on the wind-resistant frame; a positioning component, which is used to penetrate and connect the waist-shaped holes 5.1 and the corresponding fourth positioning hole 3.5 to fix the row-to-row connecting rod A5 to the wind-resistant frame. In use, by selecting different waist-shaped holes 5.1 on the row-to-row connecting rod A5 to connect and fix with the fourth positioning hole 3.5, the arrangement spacing between adjacent rows of wind-resistant frames can be adjusted.

[0039] The above technical solution allows for easy adjustment of the spacing between rows of wind-resistant frames. In use, first assemble the component support rod 3 and the wind-resistant curved rod 4 into a wind-resistant frame. Then, use a connecting structure to fix the three main cables 2 onto the component support rod 3 of the wind-resistant frame. Next, connect one end of the inter-row connecting rod A5 through the waist-shaped hole 5.1 to the fourth positioning hole 3.5 of one of the wind-resistant frames. Then, use positioning pieces to sequentially connect the waist-shaped hole 5.1 and the fourth positioning hole 3.5, but do not tighten them initially. Rotate the inter-row connecting rod A5 around the positioning hole 3.5 until the waist-shaped hole 5.1 at the other end of the inter-row connecting rod A5 aligns with the fourth positioning hole 3.5 of another wind-resistant frame. Then, use positioning pieces again to fix the waist-shaped hole 5.1 and the fourth positioning hole 3.5. Finally, tighten the positioning pieces at both ends of the inter-row connecting rod A5 to complete the installation.

[0040] In summary, this utility model, by opening multiple waist-shaped holes 5.1 on the inter-row connecting rod A5, allows for the selection of different waist-shaped holes 5.1 on the inter-row connecting rod A5 to connect and fix with the fourth positioning hole 3.5 on the wind-resistant frame, thereby adjusting the arrangement spacing between adjacent wind-resistant frame rows. This enables the connection length between wind-resistant frame rows to be adjusted according to actual conditions. Furthermore, the waist-shaped holes 5.1 allow for a certain range of positional adjustment during installation and under stress, which is crucial for adapting to the deformation of the cable structure, facilitating installation and adjustment, and releasing some of the stress caused by wind loads.

[0041] like Figure 3 and Figure 6As shown, in this embodiment, the wind-resistant frame includes: a linear component support rod 3; a V-shaped wind-resistant curved rod 4, which together with the component support rod 3 forms a triangular wind-resistant frame; three connecting structures are respectively located at the three corners of the wind-resistant frame; specifically, the connecting structure includes a first U-bolt 9 and a first U-bolt nut; at least two second positioning holes 3.3 are provided through the upper end of the component support rod 3; the rod body of the first U-bolt 9 passes through the second positioning holes 3.3 and is fixedly connected to the first U-bolt nut; an annular limiting space is formed between the first U-bolt 9 and the component support rod 3 for the main cable 2 to pass through.

[0042] The above technical solution can fix the main cable 2 to the upper end of the component support rod 3 by means of the first U-bolt 9, and the wind-resistant frame is reduced from the original three rods to only two rods: the component support rod 3 and the wind-resistant curved rod 4. This reduces the number of components, reduces the number of installation steps to a certain extent, shortens the installation time, and helps to improve installation efficiency.

[0043] like Figure 3 , Figure 5 and Figure 6 As shown, in this embodiment, at least one first mounting hole 4.1 is provided through the upper ends of both sides of the wind-resistant curved rod 4, and a third positioning hole 3.4 corresponding to the first mounting hole 4.1 is provided through the upper end of the component support rod 3. The wind-resistant device also includes a second U-bolt and a second U-bolt nut. The rod body of the second U-bolt passes through the third positioning hole 3.4 and the first mounting hole 4.1 in sequence and is connected to the second U-bolt nut.

[0044] The above technical solution can fix the wind-resistant curved rod 4 and the component support rod 3 together to form a wind-resistant frame.

[0045] like Figure 3 , Figure 4 , Figure 7 and Figure 11 As shown, in this embodiment, the positioning element is a fastening bolt 10 disposed in the fourth positioning hole 3.5. The shank of the fastening bolt 10 passes through the fourth positioning hole 3.5 and the waist-shaped hole 5.1 in sequence and is connected to a fastening nut.

[0046] The above technical solution can be used to fix the row connecting rod A5 to the wind-resistant frame by fastening bolt 10.

[0047] like Figure 4 , Figure 6 and Figure 11 As shown, in this embodiment, the component support rod 3 has a square hole 3.2 on the other side opposite to the fourth positioning hole 3.5;

[0048] The above technical solution allows for easy tightening of the nut of the fastening bolt 10 through the square hole 3.2, eliminating the need to place the nut outside the component support rod 3, thus preventing it from protruding and avoiding wear on the wind-resistant steel wire rope 7. This ensures that the flexible photovoltaic support will not rub against each other when shaking, which would affect the service life of the wind-resistant steel wire rope 7.

[0049] like Figure 2 , Figure 3 , Figure 4 and Figure 8 As shown, in this embodiment, the wind-resistant device also includes a row-to-row connecting rod B6, which is the same as the row-to-row connecting rod A5. The row-to-row connecting rod B6 is fixed to the other end of the wind-resistant frame relative to the row-to-row connecting rod A5 by a positioning member.

[0050] The above technical solution can further improve the connection stability between wind-resistant frames. By setting two inter-row connecting rods between two adjacent wind-resistant frames, the rigidity strength between the wind-resistant frames can be effectively improved.

[0051] like Figure 5 and Figure 6 As shown, in this embodiment, the wind-resistant curved rod 4 is a V-shaped rod structure with a rectangular cross-section, and the component support rod 3 is a straight rod structure with a rectangular cross-section. Both the wind-resistant curved rod 4 and the component support rod 3 have hollow interiors.

[0052] The above technical solution can reduce the weight of the wind-resistant frame.

[0053] like Figure 11 As shown, in this embodiment, one of the two adjacent wind-resistant frames is provided with two fastening bolts 10. The two fastening bolts 10 are separated from each other and form a gap. The gap is used to clamp one end of the row connecting rod A5 to restrict its rotation.

[0054] The above technical solution can prevent relative rotation of the row connecting rod A5, and further improve the connection stability between the wind-resistant frames.

[0055] like Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in this embodiment, the wind-resistant device further includes a wind-resistant steel wire rope 7 and a wiring structure for fixing the wind-resistant steel wire rope 7 to the wind-resistant frame; specifically, the wiring structure includes a third U-bolt and a third U-bolt nut, the shank of the third U-bolt passes through the second mounting hole 4.4 and / or the first positioning hole 3.1 opened on the surface of the wind-resistant frame and is fixedly connected to the third U-bolt nut, the third U-bolt and the surface of the wind-resistant frame form a positioning space for positioning the wind-resistant steel wire rope 7;

[0056] The above technical solution can reinforce the wind-resistant frame and ground anchor piles 8 with wind-resistant steel wire ropes 7, further improving the wind resistance of the wind-resistant frame for photovoltaic flexible supports, such as Figure 8 , Figure 9 and Figure 10 As shown, this section demonstrates three different installation methods for wind-resistant steel wire ropes. Different installation methods can be used on mountain slopes with varying gradients to achieve better wind resistance. In areas with low wind pressure, a combination of steel structure and steel wire rope can be used to save materials. Figure 9 and Figure 10 In windy areas, multiple steel structures can be used, such as... Figure 8 This allows it to adapt to different installation scenarios, among which Figure 8 The first installation method shown is compared to Figure 9 and Figure 10 The second and third installation methods shown in the image differ mainly in the number of connecting rods between rows.

[0057] Working principle: When using, follow the assembly sequence below:

[0058] A. As Figure 8 , Figure 9 and Figure 10 First, select the appropriate wire rope installation method 1, method 2, or method 3 based on the specific slope and terrain of the mountain.

[0059] B. First, connect the component support rod 3 and the wind-resistant curved rod 4 together with the second U-bolt and the second U-bolt nut to obtain a row of wind-resistant frames;

[0060] C. Then install a row of components 1 on the main cable 2. At a suitable place on the main cable 2 and below the components 1, use two first U-bolts 9 to connect the component support rod 3 to the two main cables 1, and use a third first U-bolt 9 to connect the wind-resistant curved rod 4 to the third cable, thereby installing the wind-resistant frame below the components 1.

[0061] D. By selecting different waist-shaped holes 5.1 on the inter-row connecting rod A5 and connecting them with the fourth positioning hole 3.5 on the component support rod 3, the arrangement spacing between adjacent wind-resistant frame rows is adjusted, so that the connection length between wind-resistant frame rows can be adjusted according to the actual situation. The wind-resistant steel wire rope 7 is installed according to the initial steel wire rope installation methods 1, 2 and 3.
