Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic panel installation, in particular to a double-sided pressing block for a steel strand flexible bracket assembly. Background Art

[0002] Photovoltaic, or photovoltaic power generation system, is a power generation system that uses the photovoltaic effect of semiconductor materials to convert solar radiation into electrical energy. The energy of the photovoltaic power generation system comes from inexhaustible solar energy, and is a clean, safe and renewable energy source. The photovoltaic power generation process does not pollute the environment or damage the ecology. The photovoltaic power generation system is divided into independent photovoltaic systems and grid-connected photovoltaic systems, which are composed of solar cell arrays, battery packs, charge and discharge controllers, inverters, AC distribution cabinets, solar tracking control systems and other equipment.

[0003] Some photovoltaic panels are fixed by steel structure frames, but in areas with complex terrain, such as mountains, some photovoltaic panels are fixed by steel strands, which have stronger wind resistance. The more common installation method is double-sided pressing blocks, which are used to connect adjacent photovoltaic panel components and photovoltaic panels to steel strands. There are certain improvements in the double-sided pressing blocks in the prior art:

[0004] First, the contact surface between the double-sided pressure block and the photovoltaic module is relatively smooth, and the connection is only based on the extrusion force of the bolts and nuts. During the subsequent frequent vibration process, the connection between the photovoltaic modules is not stable enough.

[0005] Second, the wing panels on both sides of the bilateral pressing block are respectively connected to different photovoltaic panels, and are flexibly connected through steel strands. The bending forces on the wing panels on both sides of the bilateral pressing block are uneven, and the directions may be opposite. Therefore, the connection between the wing panel and the pressing block body is prone to bending and damage. Utility Model Content

[0006] In response to the above problems, the present application provides a double-sided pressure block for a steel strand flexible bracket assembly, which solves the problem that the wing plates on both sides of the double-sided pressure block are respectively connected to different photovoltaic panels, and the flexible connection is supported by steel strands. The bending forces on the wing plates on both sides of the double-sided pressure block are uneven and the directions may be opposite. Therefore, the connection between the wing plate and the pressure block body is prone to bending and damage.

[0007] A double-sided pressure block for a flexible support of a steel strand comprises a pressure block body, four wing plates are symmetrically fixedly installed on the outer side of the pressure block body, rounded corners are provided at the connection between the wing plates and the pressure block body, two cross beams parallel to the pressure block body and the wing plates are reinforcing cross beams, the reinforcing cross beams are thickened, and the reinforcing cross beam close to the steel strand is convex.

[0008] Furthermore, two photovoltaic panel assembly connection fixing holes are symmetrically opened in the middle of the two wing plates, and the two wing plates are located at the same height of the pressing block body.

[0009] Furthermore, two steel strand connection and fixing holes are provided through one side of the pressing block body that contacts the steel strand, and a line connecting the center points of the two steel strand connection and fixing holes is perpendicular to the steel strand.

[0010] Furthermore, a convenient installation hole is provided through the middle of the pressing block body.

[0011] Furthermore, a plurality of anti-slip vertebrae are fixedly mounted on one side of the four wing plates that are close to each other.

[0012] The beneficial effects of the utility model are as follows:

[0013] (1) The utility model discloses a double-sided pressure block for a steel strand flexible bracket. The connection between the wing plate and the pressure block body is provided with a rounded corner to reduce stress concentration and prevent fracture. The two cross beams parallel to the pressure block body and the wing plate are reinforcement cross beams. The reinforcement cross beams are thickened and the stress concentration points and the points with larger loads are separately reinforced. While the overall weight is reduced, the strength and reliability of the product are guaranteed. The reinforcement cross beam close to the steel strand side is convex, which reduces the friction between the steel strand and the wing plate.

[0014] (2) The double-sided pressing block for a steel strand flexible bracket described in the utility model has a convenient installation hole running through the middle of the pressing block body, and a hollow middle design ensures the convenience of bolt installation;

[0015] The connection fixing holes of the steel strands and the photovoltaic panel components adopt a double-hole design. The double-hole connection ensures that the components will not be biased, offsetting the reduction in system efficiency and safety hazards caused by the bias of the components.

[0020] In order to more clearly illustrate the technical solutions in the embodiments of the utility model or the prior art, the utility model will be briefly introduced below in combination with the drawings and the description of the embodiments or the prior art. Obviously, the following description of the structure of the drawings is only some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work. It should be noted that the description of these embodiments is used to help understand the utility model, but does not constitute a limitation of the utility model.

[0021] like Figure 1 As shown, an embodiment of the utility model provides a double-sided pressure block for a steel strand flexible bracket, including a pressure block body 1, four wing plates 8 are symmetrically fixedly installed on the outer side of the pressure block body 1, and fillets 7 are provided at the connection between the wing plates 8 and the pressure block body 1 to reduce stress concentration and prevent breakage. The two cross beams parallel to the pressure block body 1 and the wing plates 8 are reinforcing cross beams 6. The reinforcing cross beams 6 are thickened, and stress concentration points and larger load points are separately strengthened. While the overall lightweight, the strength and reliability of the product are guaranteed. The reinforcing cross beam 6 close to the steel strand side is convex, which reduces the friction between the steel strand and the wing plates 8.

[0022] Specifically, two photovoltaic panel assembly connection fixing holes 3 are symmetrically provided in the middle of the two wing plates 8 , and the two wing plates 8 are located at the same height of the pressing block body 1 .

[0023] In this embodiment, the staff connects the photovoltaic panel assembly connection fixing hole 3 to the photovoltaic panel assembly with the help of bolts and nuts.

[0024] Specifically, two steel strand connection fixing holes 2 are formed through one side of the pressing block body 1 that contacts the steel strand, and a line connecting the center points of the two steel strand connection fixing holes 2 is perpendicular to the steel strand.

[0025] Specifically, a convenient installation hole 4 is provided through the middle of the pressing block body 1, and the hollow design in the middle ensures the convenience of bolt installation.

[0026] In this embodiment, the staff inserts the bolt from the convenient installation hole 4 into the steel strand connection fixing hole 2, and the thin end exposes the convenient installation hole 4. Then, the steel strand connection fixing hole 2 is connected to the steel strand with the help of bolts, nuts, and buckles. The reinforcement beam 6 is convex, which reduces the friction between the steel strand and the wing plate 8.

[0027] In view of the characteristics of frequent vibration and large amplitude of the steel strand flexible bracket, the pressure block body 1 is lengthened and the wing plate 8 is widened compared with the prior art, which ensures the contact surface with the photovoltaic component, increases the friction, and increases the force area, making the component connection more stable. The steel strand connection fixing hole 2 and the photovoltaic panel component connection fixing hole 3 both adopt a double-hole design. The double-hole connection ensures that the component will not be offset, offsetting the reduced system efficiency and safety hazards caused by the offset of the component.

[0028] Specifically, a plurality of anti-slip vertebrae 5 are fixedly mounted on one side of the four wing plates 8 that are close to each other.

[0029] In this embodiment, the contact surface between the wing plate 8 and the photovoltaic module adopts an anti-slip cone 5 with a sharp tooth design, which effectively increases the gripping force of the double-sided pressure block on the photovoltaic module.

[0030] How it works:

[0031] The staff uses bolts and nuts to connect the photovoltaic panel assembly connection fixing hole 3 to the photovoltaic panel assembly.

[0032] The staff inserts the bolt from the convenient installation hole 4 into the steel strand connection fixing hole 2, with the thin end exposed through the convenient installation hole 4, and then uses bolts, nuts, and buckles to connect the steel strand connection fixing hole 2 to the steel strand, and the reinforced crossbeam 6 is convex, which reduces the friction between the steel strand and the wing plate 8.

[0033] In view of the characteristics of frequent vibration and large amplitude of the steel strand flexible bracket, the pressure block body 1 is lengthened and the wing plate 8 is widened compared with the prior art, which ensures the contact surface with the photovoltaic component, increases the friction, and increases the force area, making the component connection more stable. The steel strand connection fixing hole 2 and the photovoltaic panel component connection fixing hole 3 both adopt a double-hole design. The double-hole connection ensures that the component will not be offset, offsetting the reduced system efficiency and safety hazards caused by the offset of the component.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
