Description

Technical Field

[0001] The utility model relates to the technical field of power transmission lines, in particular to a wind vibration prevention device for power transmission lines. Background Art

[0002] With the continuous progress and development of my country's construction technology, integrated and large-scale super high-rise buildings are increasingly valued and favored by the industry in my country's construction field. During the construction of super high-rise buildings, a large amount of materials, equipment and personnel are involved in the transportation. The problem of power transmission is a key issue that will have a significant impact on the construction efficiency and progress of super high-rise buildings. Therefore, the safety, reliability and uninterrupted power transmission of super high-rise buildings are of great significance to the construction of super high-rise buildings; most of the wires used in the construction of super high-rise buildings are external accompanying transmission lines, most of which are bound with aluminum binding wires. This type of transmission line swings in the wire slot. The stronger the wind, the more violent the swing. When the wind is too strong, the transmission line will float out of the wire slot, affecting normal safety work;

[0003] For example, the public document: CN207994574U, named "Power Transmission Line Wind Protection Device", includes a device body and a clip, a No. 1 ring is provided at one end of the device body, and a No. 2 ring is provided at the other end of the device body, and wire holes are fixedly connected in the No. 1 ring and the No. 2 ring, both sides of the No. 1 ring are fixedly connected with No. 1 ring ears, and both sides of the No. 2 ring are fixedly connected with No. 2 ring ears, a fixing nut is fixedly provided at the bottom of the No. 2 ring ear, and a No. 1 screw is connected to the upper end of the fixing nut, by providing a clip that can be movably connected with the No. 1 ring and the No. 2 ring, the transmission line is passed through the semicircular metal ring and inserted into the wire hole, the No. 2 screw is tightened to fix the transmission line, and the connection distance between the No. 1 ring and the No. 2 ring is fixed by the No. 1 screw, which solves the defects of frequent line breakage faults in the transmission line, avoids the problem of the current transmission line floating out of the wire slot due to wind swinging, and realizes the maintenance-free transmission line. The utility model has a simple structure and is easy to operate, and greatly improves the wind protection performance of the transmission line.

[0004] Although the above-mentioned existing power transmission line windproof structure can limit the wire harness, the windproof structure itself is still easily affected by strong winds when it is located at a high altitude, thereby affecting the safety of the wire harness inside it; therefore, it does not meet the existing needs. We have proposed a power transmission line wind vibration protection device. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] See also Figure 1-5 The utility model provides an embodiment: a power transmission line wind vibration protection device, comprising: a first wire harness assembly 1, a second wire harness assembly 2 is arranged below the first wire harness assembly 1, and the first wire harness assembly 1 and the second wire harness assembly 2 are combined together, two left and right wire harness cavities 9 for limiting the wire harness are opened between the first wire harness assembly 1 and the second wire harness assembly 2, grooves 5 are opened on both sides of the upper surface of the first wire harness assembly 1, and an anti-wind bracket 6 with an inclination angle is arranged inside the groove 5, a threaded support rod 8 is arranged at one end of the anti-wind bracket 6 away from the groove 5, and an air guide hole 7 for reducing wind resistance is opened on the outer wall of the anti-wind bracket 6.

[0023] After the first wire harness assembly 1 and the second wire harness assembly 2 are combined together, the wire harness cavity 9 therebetween can limit and constrain the wire harness, thereby achieving the effect of resisting wind vibration. After the first wire harness assembly 1 and the second wire harness assembly 2 are combined, their own wind resistance is enhanced by the wind-resistant bracket 6. The wind-resistant bracket 6 is an outwardly deployable type, which can direct lateral wind force. The top of the wind-resistant bracket 6 is fixed by a threaded support rod 8 to improve stability and firmness. The wind guide hole 7 can allow lateral wind to pass through, thereby reducing wind resistance and improving wind resistance.

[0024] Further, the first wire harness assembly 1 is an M-type component, and the second wire harness assembly 2 is a W-type component.

[0025] The M-type and W-type structures can be assembled together and form a cavity between them to facilitate the restriction of the wiring harness.

[0026] See also Figure 5 An upper slot 12 is provided at the middle position of the upper surface of the first wiring harness assembly 1 , and second assembly bolts 14 for fixing the wind-resistant bracket 6 are installed on the inner walls on both sides of the upper slot 12 .

[0027] The wind-resistant bracket 6 and the first wiring harness assembly 1 are detachable structures. The bottom of the wind-resistant bracket 6 matches the shape of the groove 5, so that the bottom of the wind-resistant bracket 6 can be inserted into the groove 5. After insertion, the openings on the bottom side walls of the wind-resistant bracket 6 are aligned with the openings on the side walls of the groove 5. The bottom of the wind-resistant bracket 6 is fixed by installing bolts at the upper groove 12. In subsequent disassembly and maintenance, there is no need to disassemble and remove the top of the wind-resistant bracket 6 and the threaded support rod 8. The bottom disassembly makes maintenance operations more convenient.

Specifically, the combined assembly part 3 is combined with the combined assembly part 3 by mortise and tenon method.

[0031] The combination of the combined assembly part 3 and the combined assembly groove 4 can improve the firmness of the first wiring harness assembly part 1 and the second wiring harness assembly part 2. By docking, it is convenient for the user to dock the two together first, which is more convenient for the subsequent installation of bolts.

[0032] See also Figure 1 A rubber shock-absorbing pad 10 is bonded to the inner wall of the wiring harness cavity 9.

[0033] The rubber shock-absorbing pad 10 is used to improve the anti-slip and shock-absorbing properties in the wiring harness cavity 9, and to prevent the wiring harness from directly contacting the inner wall of the cavity, thereby preventing the inner wall from being worn.

[0034] Working principle: When in use, the combined assembly part 3 of the first wiring harness assembly part 1 is connected with the combined assembly groove 4 of the second wiring harness assembly part 2, and then the first wiring harness assembly part 1 and the second wiring harness assembly part 2 are fixed together by bolts to constrain the wiring harness in the wiring harness cavity 9 formed by the combination of the two wiring harness assemblies;

[0035] The wind-resistant bracket 6 and the first wiring harness assembly 1 are detachable structures, and the bottom of the wind-resistant bracket 6 matches the shape of the groove 5, so that the bottom of the wind-resistant bracket 6 can be inserted into the groove 5. After insertion, the opening on the bottom side wall of the wind-resistant bracket 6 is aligned with the position of the opening on the side wall of the groove 5, and the bottom of the wind-resistant bracket 6 is fixed by the bolts installed at the upper slot 12;

[0036] After the first wiring harness assembly 1 and the second wiring harness assembly 2 are combined, their own wind resistance is enhanced by the wind-resistant bracket 6. The wind-resistant bracket 6 is deployed outward and can absorb lateral wind force. The top of the wind-resistant bracket 6 is fixed by a threaded support rod 8 to improve stability and firmness. The wind guide hole 7 can allow lateral wind to pass through, which is used to reduce wind resistance and improve wind resistance.
