Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of power transmission equipment, and specifically relates to a connection structure for suppressing conductor galloping and a hanging insulator. Background Technology
[0002] Transmission lines are prone to conductor galloping under wind loads. Traditional suspension insulator fittings lack effective energy dissipation mechanisms and cannot effectively suppress conductor galloping. This results in the suspension insulator strings and connecting fittings bearing alternating loads, which may lead to fatigue failure over long periods. Existing energy-dissipating components can only dissipate energy from galloping in one direction, reducing the effectiveness of conductor galloping prevention.
[0003] Therefore, in view of the above-mentioned technical problems, a connection structure and hanging insulator for suppressing conductor galloping are designed to realize energy dissipation when the conductor gallops in multiple directions. The simple structure and convenient installation are technical problems that need to be solved by those skilled in the art. Utility Model Content
[0004] To address the aforementioned problems, this utility model provides a connection structure and a hanging insulator for suppressing conductor galloping, which can dissipate energy when the conductor gallops in multiple directions, and is simple in structure and easy to install.
[0005] To achieve the above objectives, this utility model provides the following solution:
[0006] A connection structure for suppressing conductor galloping includes an outer sleeve, a transmission rod with one end extending into the inner sleeve and the other end extending out of the outer sleeve, and damping plates with both ends clamped to the inner wall of the outer sleeve and the transmission rod. The damping plates are X-shaped. The end of the transmission rod that mates with the outer sleeve is provided with an end plate that mates with the outer sleeve and restricts the range of movement of the transmission rod along the axis of the outer sleeve.
[0007] Preferably, the mating end of the outer sleeve and the transmission rod is provided with a limiting cavity for limiting the end plate, and at least two first receiving grooves for accommodating the damping plate are provided on the inner wall of the outer sleeve along the axial direction, and a first connecting member is provided on the protruding end of the outer sleeve away from the transmission rod.
[0008] Preferably, the outer sleeve includes an upper housing and a lower housing that can be snapped together.
[0009] Preferably, the first receiving groove is evenly distributed along the axial direction of the outer sleeve.
[0010] Preferably, the transmission rod further includes a second connector disposed on the side away from the end plate, and a second receiving groove disposed between the second connector and the end plate, which cooperates with the first receiving groove to achieve the engagement of the damping plate.
[0011] Preferably, the gap between the mating surfaces of the end plate and the outer sleeve is 10mm to 20mm.
[0012] Preferably, the outer sleeve is a Q345B steel sleeve, and the transmission rod is a Q345B steel rod.
[0013] Preferably, the damping plate is an LY225 steel damping plate with a thickness of 6mm to 8mm, an end width of 24mm to 32mm, and a neck width of 4mm to 6mm.
[0014] Preferably, the number of damping plates is 8 to 12, and they are evenly distributed along the circumference of the transmission rod.
[0015] This utility model also discloses a hanging insulator that uses the conductor galloping suppression connection structure as described above, including a hanging insulator body and hardware, wherein the conductor galloping suppression connection structure is disposed between the hanging insulator body and the hardware.
[0016] The present invention achieves the following technical advantages over the prior art:
[0017] The range of movement of the transmission rod along the axis of the outer sleeve is limited by the outer sleeve. The damping plate is set in an X shape, with one end of the damping plate being engaged with the inner wall of the outer sleeve and the other end of the damping plate being engaged with the transmission rod. When the conductor swings along the axis of the outer sleeve or in a direction perpendicular to the axis of the outer sleeve, the transmission rod drives the damping plate to undergo shear deformation. Energy is dissipated through plastic deformation. All sections of the damping plate can yield simultaneously, making full use of the material's deformation capacity. This can realize energy dissipation when the conductor dances in multiple directions, and the structure is simple and easy to install. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] The purpose of this invention is to provide a connection structure and hanging insulator for suppressing conductor galloping, which can realize energy dissipation when the conductor gallops in multiple directions, and has a simple structure and is easy to install.
[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0028] refer to Figures 1-4 The conductor galloping suppression connection structure disclosed in this embodiment of the present invention includes at least an outer sleeve 2. A transmission rod 3 is disposed inside the outer sleeve 2. One end of the transmission rod 3 extends into the outer sleeve 2, and the other end extends out of the outer sleeve 2. A damping plate 23 is engaged between the inner wall of the outer sleeve 2 and the transmission rod 3. One end of the damping plate 23 is engaged with the inner wall of the outer sleeve 2, and the other end is engaged with the transmission rod 3. The damping plate 23 is X-shaped. An end plate 31 is provided at the mating end of the transmission rod 3 and the outer sleeve 2. The end plate 31 engages with the outer sleeve 2, thereby limiting the conductor galloping. The range of movement of the transmission rod 3 along the axis of the outer sleeve 2 is determined by setting the damping plate 23 in an X-shape, with one end of the damping plate 23 engaged with the inner wall of the outer sleeve 2 and the other end of the damping plate 23 engaged with the transmission rod 3. When the conductor 5 swings along the axis of the outer sleeve 2 or swings in a direction perpendicular to the axis of the outer sleeve 2, the transmission rod 3 drives the damping plate 23 to undergo shear deformation. Energy is dissipated through plastic deformation. All sections of the damping plate 23 can yield simultaneously, giving full play to the deformation capacity of the material. This can realize energy dissipation when the conductor 5 swings in multiple directions, and the structure is simple and easy to install.
[0029] refer to Figures 1-4 In one embodiment, the mating end of the outer sleeve 2 and the transmission rod 3 is provided with a limiting cavity for limiting the end plate 31. The inner wall of the outer sleeve 2 is provided with at least two first receiving grooves along the axial direction of the outer sleeve 2 to accommodate the damping plate 23. The protruding end of the outer sleeve 2 away from the transmission rod 3 is provided with a first connecting member. By providing the limiting cavity, the end plate 31 can be limited, avoiding excessive deformation of the damping plate 23 and breakage. Providing at least two first receiving grooves, that is, providing at least two damping plates 23, can improve the energy dissipation effect. Furthermore, by providing the first connecting member, it is convenient to connect with the hanging insulator.
[0030] It should be noted that the first connecting piece is connected to the suspension insulator body 1 by bolts.
[0031] refer to Figures 1-4 In one embodiment, the outer sleeve 2 includes an upper shell 21 and a lower shell 22 that can be snapped together. By snapping together the upper shell 21 and the lower shell 22, the entire structure can be easily assembled and disassembled.
[0032] refer to Figures 1-4 As one implementation method, the first receiving groove is evenly distributed along the axial direction of the outer sleeve 2. The even distribution can make the damping plate 23 work synchronously when subjected to force, avoid uneven energy distribution caused by local overload, thereby improving the overall structure's ability to absorb vibration or impact energy. The even distribution can balance the mechanical stress of each part and reduce the risk of fatigue fracture caused by local stress concentration.
[0033] refer to Figures 1-4 In one embodiment, the transmission rod 3 further includes a second connecting member disposed on the side away from the end plate 31. A second receiving groove is provided between the second connecting member and the end plate 31. The first receiving groove and the second receiving groove cooperate to achieve the engagement of the damping plate 23. That is, one end of the damping plate 23 is engaged in the first receiving groove, and the other end of the damping plate 23 is engaged in the second receiving groove, and the number of the first receiving groove and the second receiving groove are equal.
[0034] refer to Figures 1-4 In one embodiment, the gap between the mating surfaces of the end plate 31 and the outer sleeve 2 is 10mm to 20mm, that is, the range of movement of the transmission rod 3 along the axis of the outer sleeve 2 is 10mm to 20mm.
[0035] refer to Figures 1-4 In one implementation, the outer sleeve 2 is a Q345B steel sleeve, and the transmission rod 3 is a Q345B steel rod.
[0036] refer to Figures 1-4In one embodiment, the damping plate 23 is an LY225 steel damping plate 23 with a thickness of 6mm to 8mm, an end width of 24mm to 32mm, and a neck width of 4mm to 6mm. The ends of the damping plate 3 are respectively snapped into the first receiving groove and the second receiving groove.
[0037] refer to Figures 1-4 In one implementation, the number of damping plates 23 is 8 to 12, and they are evenly distributed along the circumference of the transmission rod 3. That is, damping plates 23 are provided on the entire circumference of the transmission rod 3, which can evenly share the losses caused by the external environment (such as wind vibration, corona, etc.), slow down the deterioration rate of insulators and fittings, and reduce maintenance frequency and cost.
[0038] refer to Figure 5 This utility model also discloses a hanging insulator, including a hanging insulator body 1 and a fitting. A conductor galloping suppression connection structure is disposed between the hanging insulator body 1 and the fitting. Specifically, the hanging insulator body 1 is connected to a first connecting member, the conductor 5 is connected to a second connecting member, and the fitting is a tensioning ring 4.
[0039] Any adaptive changes made according to actual needs are within the protection scope of this utility model.
[0040] It should be noted that, for those skilled in the art, it is obvious that this utility model is not limited to the details of the above exemplary embodiments, and that this utility model can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered as exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description.
