Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of composite insulators, in particular to a composite insulator with a windproof and earthquake-resistant structure. Background Art
[0002] Composite insulators can be divided into line composite insulators and power station and electrical appliance composite insulators. They can also be divided into rod-shaped suspension composite insulators, pin-type composite insulators, cross-arm composite insulators, pillar composite insulators, wind-proof composite insulators, etc. In the early years, insulators were mostly used on electric poles. With the development of science and technology, they gradually developed into high-type high-voltage electric wire connection towers with many disc-shaped insulators hung at one end. It is to increase the creepage distance. It is usually made of glass or ceramic, which is called an insulator. Insulators play two basic roles in overhead transmission lines, namely supporting the conductors and preventing current from returning to the ground. These two roles must be guaranteed. Insulators should not fail due to various electromechanical stresses caused by changes in environmental and electrical load conditions. Otherwise, the insulators will not have a significant effect, which will damage the use and operation life of the entire line. Existing insulators are generally used for outdoor electric poles, which will be affected by bad weather and cause damage to the insulators.
[0003] In the process of realizing the utility model, the inventors found that the prior art had the following problems: 1. Existing insulators are exposed to the atmosphere on the transmission line and are affected by wind, which causes the insulators to be overstressed, bent or tilted, and in severe cases may even cause the insulators to break; 2. Existing insulators are also affected by vibrations on the transmission line, causing vibration, resonance or fatigue damage to the insulator rods, insulator strings or the insulators themselves. Utility Model Content
[0004] The purpose of the utility model is to provide a composite insulator with a windproof and earthquake-resistant structure to solve the problem in the above background technology that the insulator is exposed to the atmospheric environment and is affected by wind, resulting in excessive force, bending or tilting. To achieve the above purpose, the utility model provides the following technical solution: a composite insulator with a windproof and earthquake-resistant structure comprises a composite insulator body, a connecting ring is provided on one side of the composite insulator body, and a rotating disk is provided on one side of the connecting ring;
[0005] A spring is welded inside the connecting ring, a fixing ring is welded on one side of the spring, a support rod is welded below the connecting ring, a supporting bottom plate is welded below the support rod, and a shock-absorbing damper is installed on one side of the fixing ring by screws;
[0006] A fixing plate is plugged into one side of the turntable via a latch, a threaded rod is fitted inside the fixing plate, and an anti-skid pad is glued below the threaded rod.
[0007] Further preferably, the fixing ring forms an elastic structure with the connecting ring through a spring.
[0008] Further preferably, the connecting ring and the support rod are integrally connected, and the support rod and the support base plate are integrally connected.
[0009] Further preferably, two shock-absorbing dampers are horizontally mirrored on both sides of the fixing ring.
[0010] Further preferably, the external structural dimensions of the threaded rod are consistent with the internal structural dimensions of the fixing plate.
[0011] Further preferably, the internal structural dimensions of the fixing ring are consistent with the external structural dimensions of the composite insulator body.
[0012] Compared with the prior art, the utility model has the following beneficial effects:
[0013] In the utility model, a circle of spring is provided on the outside of the insulator. When the wind force affects the insulator to shift, the spring will undergo elastic deformation, absorb and store energy, and then restore its original state with a reverse force. The force in this direction can offset or reduce the pressure of the external force, thereby preventing the insulator from being deformed and damaged due to the influence of wind force.
[0014] In the utility model, the insulator is slowed down by a spring. When vibration occurs, the shock-absorbing resistance below converts the remaining energy into heat energy for dissipation, thereby reducing the amplitude of the vibration. A cross support rod is also provided below to provide stable support. The existing insulator has only one support point and is easy to move. A movable and fixed support point is added to facilitate stable support. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the utility model.
[0021] See also Figures 1 to 4 The utility model provides a technical solution: a composite insulator with a windproof and earthquake-resistant structure, comprising a composite insulator body 1, a connecting ring 2 is provided on one side of the composite insulator body 1, and a rotating disk 3 is provided on one side of the connecting ring 2;
[0022] A spring 202 is welded inside the connecting ring 2, a fixing ring 201 is welded to one side of the spring 202, a support rod 204 is welded below the connecting ring 2, a support base plate 205 is welded below the support rod 204, and a shock absorbing damper 203 is installed on one side of the fixing ring 201 by screws;
[0023] A fixing plate 302 is inserted into one side of the turntable 3 through a latch, a threaded rod 301 is attached to the inside of the fixing plate 302 , and an anti-skid pad 303 is glued to the bottom of the threaded rod 301 .
[0024] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, the fixing ring 201 forms an elastic structure with the connecting ring 2 through the spring 202; because the insulator is exposed to the atmospheric environment on the transmission line and is affected by wind, strong wind may generate great wind pressure on the insulator, causing the insulator to be overstressed, bent or tilted, and even cause the insulator to break in severe cases; now the improvement is provided with a fixing ring 201, and a circle of the fixing ring 201 is provided with a spring 202. When the wind force is too strong, through the elasticity and deformation ability of the spring 202, when an external force acts on the spring 202, the spring 202 will undergo elastic deformation, absorb and store energy, and then restore to its original state with a reverse force. The force in this direction can offset or reduce the pressure of the external force, thereby achieving the effect of protecting the fixing ring 201.
[0025] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, the connecting ring 2 and the support rod 204 are integrally connected, and the support rod 204 and the support base plate 205 are integrally connected; because the existing insulators are not supported by any additional objects after installation, they are easily displaced when the wind is strong, causing damage to the insulators. Now, the improved connecting ring 2 connects the support rod 204 and the support base plate 205 to increase the bearing surface, avoid displacement and damage when the wind is strong, thereby achieving the function of connecting and supporting the support rod 204.
[0026] In this embodiment, Figure 3 As shown, two shock-absorbing dampers 203 are respectively provided on both sides of the fixing ring 201 in a horizontal mirror image. Since the insulators are also affected by vibrations on the transmission line, which may cause vibration, resonance or fatigue damage to the insulator rods, insulator strings or the insulators themselves, shock-absorbing dampers 203 are now added on both sides of the fixing ring 201. The shock-absorbing dampers 203 usually adopt a combination of springs 202 and damping elements, wherein the springs 202 are responsible for storing and releasing energy, and the damping elements are responsible for dissipating energy. When vibration acts on the system, the springs 202 absorb part of the vibration energy and store it, while the damping elements convert the remaining energy into heat energy for dissipation, thereby reducing the amplitude of the vibration, thereby achieving the shock-absorbing effect of the shock-absorbing dampers 203.
[0027] In this embodiment, Figure 1 , Figure 2 and Figure 4 As shown, the external structural dimensions of the threaded rod 301 are consistent with the internal structural dimensions of the fixing plate 302; since the existing insulator is fixedly supported at the bottom, the top is easy to move and has only one fixed point, the fixing plate 302 is now improved to be able to rotate in a direction through the turntable 3, and the threaded rod 301 is rotated to fix the anti-slip pad 303 at the bottom of the threaded rod 301, thereby achieving two support points under the insulator through the threaded rod 301 to increase stability.
[0028] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, the internal structural dimensions of the fixing ring 201 are consistent with the external structural dimensions of the composite insulator body 1; because the dimensions of the fixing ring 201 are consistent with those of the composite insulator body 1, the composite insulator body 1 is fixed by the fixing ring 201, and when movement occurs, the objects connected by the fixing ring 201 are protected, thereby achieving the protection effect of the fixing ring 201.
[0029] The use method and advantages of the utility model: When the composite insulator with windproof and earthquake-resistant structure is used, the working process is as follows:
[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, first, the fixing plate 302 is snapped into the fixed position, and the threaded rod 301 is rotated clockwise to fix the anti-skid pad 303. When the composite insulator body 1 is moved by external force, it moves to one side through the fixing ring 201, and the spring 202 moves to one side to reset, and the shock absorbing damping 203 absorbs and relieves it. The connecting ring 2 and the supporting base plate 205 are fixedly supported by the supporting rod 204.
[0031] The above shows and describes the basic principle, main features and advantages of the utility model. Technical staff in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
