[0030] In the description of the present application, it is necessary to explain that, unless otherwise defined, all the technical and scientific terms used in the present application are the same as the meanings understood by the persons skilled in the art. The terms used in the specification of the present application are only for the purpose of describing the specific embodiments and are not intended to limit the present application, and the specific meanings of the above terms in the present application can be understood by the persons skilled in the art.

[0031] An embodiment of the present application provides a damper, specifically, please refer to Figure 1 and Figure 2 , Figure 1 The structure of the damper provided by one embodiment of the present application is shown in the figure, Figure 2 It is a side view of the same damper, including a wire clamp, a fastener, a steel strand 11, a first damper weight 131 and a second damper weight 132.

[0032] Among them, as shown in Figure 1 , the wire clamp includes a wire clamping end 12 and a connecting end 121, the upper part of the wire clamp is the wire clamping end 12, which is used to clamp the wire to be clamped 20 in work, and the lower part of the wire clamp is the connecting end 121, which is used to connect the wire clamp and the damper weight, and the damper weight includes the first damper weight 131 and the second damper weight 132.

[0033] Specifically, the wire clamping end 12 of the wire clamp includes a first clamping section 123 and a second clamping section 122, wherein, as shown in Figure 2 , the first clamping section 123 is an integral structure with the lower connecting end 121, and the second clamping section 122 can be separated from the main body of the damper.

[0034] The working surfaces of the first clamping section 123 and the second clamping section 122 can be enclosed to form a clamping channel matched with the wire to be clamped 20.

[0035] The working surfaces of the first clamping section 123 and the second clamping section 122 are provided with rubber pads, which are completely matched with the wire to be clamped when the wire clamping end clamps the wire to be clamped.

[0036] Specifically, the second clamping section 122 is also hinged with the first clamping section 123 through the lowest position, and the outer side surface of the bottom of the second clamping section is an inclined surface gradually close to the inner side surface from top to bottom, when the first clamping section 123 and the second clamping section 122 are not fastened by the fastener, i.e. in the non-working mode, the second clamping section 122 is hingedly connected with the entire main body of the damper through the bottom of the second clamping section 122.

[0037] As shown in Figure 1As shown, the wire clamp is further provided with a second hole position 14, which is a fastening hole position corresponding to the first clamping section 123 and the second clamping section 122. In the normal working state of the damper, the first clamping section 123 and the second clamping section 122 are fixed by the fastener passing through the second hole position 14.

[0038] Specifically, the fastener of the embodiment is a stud, which can be a hexagonal bolt. The stud is provided with external threads, and the inner side of the second hole position 14 is provided with internal threads matching the external threads. The hexagonal bolt can be tightened or loosened by using a hexagonal wrench tool, has high strength and stability, and can provide sufficient fastening force to ensure that the wire clamp is firmly fixed on the wire. The standardized design of the hexagonal bolt also facilitates the replacement and maintenance of spare parts, reduces maintenance costs, and further enhances the reliability and durability of the damper.

[0039] The wire clamp is further provided with a first hole position 15 passing through the first clamping section 123 and the second clamping section 122. The first hole position 15 is an auxiliary hole position corresponding to the first clamping section 123 and the second clamping section 122. The first hole position 15 can be passed through by external auxiliary tools to achieve the pre-fixing of the damper on the wire to be clamped 20.

[0040] The steel strand 11 passes through the connecting end 121 of the wire clamp, and one end of the steel strand 11 is connected to the first damper weight 131, and the other end of the steel strand 11 is connected to the second damper weight 132.

[0041] The first hole position 15 of the embodiment serves as an auxiliary hole position for assisting the installation process when the damper is installed on the wire to be clamped 20. Specifically, before the wire clamp is fastened on the wire to be clamped 20 by the fastener through the second hole position 14, the damper is first pre-fixed on the wire to be clamped 20 through the first hole position 15. The auxiliary hole position can be passed through by a wire spacer wrench such as a wire spacer wrench and simply fixed on the wire to be clamped 20, so that the first clamping section 123 and the second clamping section 122 form a merged state of contact, so that the wire to be clamped 20 is clamped between the first clamping section 123 and the second clamping section 122. Then the hexagonal bolt is tightened and fixed on the first clamping section 123 and the second clamping section 122 using the installation tool. Pre-fixing the damper through the auxiliary hole position can reduce the damping force that needs to be overcome during the process of tightening the hexagonal bolt when the wire clamp clamps the wire to be clamped 20, increase the fastening effect of the fastener and the second hole position 14, and facilitate the installation process of the damper.

[0042] The setting of the auxiliary hole position provides a stable support point for the installation and removal operation, making it easier to align and fix the damper during installation. In addition, this auxiliary method effectively disperses the stress that may occur during tightening, protecting the conductor and the damper itself, and prolonging its service life. By first clamping with the auxiliary hole position and then tightening, it ensures that the damper can be firmly and stably installed on the conductor, maintaining good damping effect even in harsh weather conditions.

[0043] Preferably, to enhance the clamping effect of the wire clamp on the conductor to be clamped 20, the position of the fastening hole, i.e. the second hole position 14, is set at the centroid position of the front view of the second clamping section 122 of the wire clamp.

[0044] To further reduce the damping force that needs to be overcome when tightening the hexagonal bolt, the position of the first hole position 15 is tested for the damping force that needs to be overcome during installation. The results show that when the distance between the center of the first hole position 15 and the center of the second hole position 14 is equal to the distance between the second hole position 14 and the axis of the conductor to be clamped 20, the damping force to be overcome is the smallest, as shown in Table 1:

[0045]

[0046] Where L1 is the distance between the second hole position 14 and the axis of the conductor to be clamped 20, L2 is the distance between the center of the first hole position 15 and the center of the second hole position 14, and Fc is the measured damping force during tightening of the bolt.

[0047] Preferably, the damper of the present embodiment also includes a safety module, which is provided on the first clamping section 123 and includes a latch hole position 16 and a safety latch that passes through the latch hole position and penetrates the first clamping section on both sides. The safety latch is made of high-strength aluminum alloy material. The design of the safety module provides additional safety for the damper, effectively preventing the damper from dislocating even in extreme cases where the bolt fails. The insertion and removal process of the latch is simple and quick, and only needs to be inserted after the tightening of the hexagonal bolt in the tightening module. Once the bolt in the tightening module fails for some reason, the latch will play its safety role and prevent it from falling off the conductor. This design not only improves the safety of the damper, but also effectively avoids the line faults and safety accidents that may be caused by the falling of the damper. At the same time, the replaceable design of the latch greatly facilitates subsequent maintenance and repair work, reducing the operation and maintenance cost.

[0048] In addition, the overall structure of the damper of the present embodiment takes into account the weight distribution during design, and the first damper weight 131 and the second damper weight 132 have the same weight and shape to ensure the balance and stability of the damper on the conductor to be clamped 20, reducing the impact of vibration on the conductor to be clamped 20.

[0049] The length of the steel strand 11 is greater than the length of the wire clamping end 12. In the length direction of the steel strand 11, the length of the wire clamping end 12 is equal to the length of the connecting end 121, and the length is set reasonably, which not only ensures that the damper has a better wire clamping effect on the conductor, but also saves production materials and reduces the production cost of the damper, and effectively suppresses the vibration of the conductor due to wind force, greatly reduces the operation and maintenance cost of the power grid and the risk of manual maintenance work.

[0050] Preferably, the inside of the first hole position 15 and the bolt hole position 16 of the embodiment is provided with an anti-skid thread, and the anti-skid thread of the first hole position 15 is used to reduce the relative position phenomenon between the first clamping section 123 and the second clamping section 122 caused by the fastening behavior when auxiliary installation work is performed.

[0051] Preferably, the surface of the wire clamping end 12 of the embodiment is provided with a waxy anticorrosive coating to prevent corrosion phenomenon at the contact part of the damper and the conductor 20 to be clamped during the working process due to long-term exposure to the natural environment.

[0052] The damper of the application makes the installation and disassembly process of the damper more convenient and fast through the design of the auxiliary hole position and the fastener, the hollow hole design of the auxiliary hole position allows the use of a conductor spacer wrench auxiliary tool to perform preliminary clamping, reduces the damping force required in the fastening process, thereby improving the installation efficiency, the design of the hexagonal bolt makes the fastening and loosening operation more convenient, and reduces the difficulty of maintenance and replacement. The bolt made of high-strength alloy can prevent the damper from dislocating when the bolt in the fastener fails. This design effectively avoids the line failure and safety accident that may be caused by the falling of the damper, and improves the safety and stability of the damper under extreme conditions. The anti-skid rubber pad and anti-skid pattern on the inner side of the wire clamping end further enhance the wire clamping effect and ensure that the damper remains firm during vibration.

[0053] The above-described embodiments only express several embodiments of the application, and the description is more specific and detailed, but it cannot be understood as limiting the scope of the patent of the application. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the application, several modifications and improvements can be made, which are within the protection scope of the application. Therefore, the protection scope of the patent of the application should be subject to the appended claims.
