Description

Technical Field

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

[0002] Photovoltaic panels have no moving parts and can operate for long periods of time without causing any loss. Simple photovoltaic cells can provide energy for watches and computers. More complex photovoltaic systems can provide lighting for houses and power the grid. Photovoltaic panel components can be made into different shapes, and the components can be connected to generate more electricity. Photovoltaic panel components are used on rooftops and building surfaces, and are even used as part of windows, skylights or shading devices. These photovoltaic facilities are often referred to as building-attached photovoltaic systems.

[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 methods are single-sided blocks and double-sided blocks. When the photovoltaic panels at the edge are connected to the steel strands, single-sided blocks are used. There are certain improvements in the single-sided blocks in the existing technology:

[0004] First, some single-sided pressure blocks pursue lightweight, the thickness of the overall frame is relatively thin, and only one side of the single-sided pressure block is connected to the photovoltaic panel assembly. The force on both sides is uneven, and deformation and bending are prone to occur at the stress concentration point. The service life is short, and the connection strength between the damaged single-sided pressure block and the photovoltaic panel assembly and steel strand is reduced, which makes the photovoltaic panel shake more severely, which may cause greater losses.

[0005] Second, the contact surface between the single-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. Utility Model Content

[0008] The two cross beams parallel to the wing plate and the pressing block body are reinforced cross beams, which are thickened and the reinforced cross beam close to the steel strand is convex.

[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.

[0023] 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.

[0024] like Figure 1 As shown, an embodiment of the utility model provides a single-sided pressure block for a steel strand flexible bracket, including a pressure block body 1, two wing plates 8 are fixedly installed on the outside of the pressure block body 1, a rounded corner 7 is provided at the connection between the wing plate 8 and the pressure block body 1, and a rounded corner 7 is provided at the outer corner of the pressure block body 1 away from the wing plate 8.

[0025] In this embodiment, the rounded corners 7 are used to reduce stress concentration and prevent fracture.

[0026] Specifically, the two cross beams parallel to the pressing block body 1 and the wing plate 8 are the reinforcing cross beams 6, and the reinforcing cross beams 6 are thickened.

[0027] In this embodiment, stress concentration points and larger load points are reinforced separately, thereby ensuring the strength and reliability of the product while reducing the overall weight.

[0028] Specifically, the reinforcement beam 6 close to the side of the steel strand is convex.

[0029] In this embodiment, the friction between the steel strands and the wing plate 8 is reduced.

[0030] 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.

[0031] Specifically, a convenient installation hole 4 is formed through the middle of the pressing block body 1 .

[0032] 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.

[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] Specifically, two photovoltaic panel assembly connection fixing holes 3 are symmetrically provided in the middle of the wing plate 8 .

[0035] 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.

[0036] Specifically, a plurality of anti-slip vertebrae 5 are fixedly mounted on the sides of the two wing plates 8 that are close to each other.

[0037] 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 single-sided pressure block on the photovoltaic module.

[0038] How it works:

[0039] The staff uses bolts and nuts to connect the photovoltaic panel assembly connection fixing hole 3 to the photovoltaic panel assembly.

[0040] The staff inserts the bolt from the convenient installation hole 4 into the steel strand connection fixing hole 2, with the thin end exposed from 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. The reinforcement beam 6 close to the steel strand side is convex to reduce the friction between the steel strand and the wing plate 8.

[0041] 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.

[0042] 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.
