[0002] With the rapid development of society and economy, people's lives are becoming increasingly inseparable from the demand for electricity, and power construction is becoming more and more widespread. In the process of power construction, overhead cables are needed to complete the laying of transmission lines. Transmission lines are achieved by using transformers to step up the voltage of the electrical energy generated by generators, and then connecting it to the transmission line through control equipment such as circuit breakers.

[0003] Currently, during the laying process of power cables, the cables are quite long. Due to the weight of the cables themselves and factors such as weather, there is a large tension in the cables. When encountering strong winds, they will sway significantly, and if the swaying is severe, they will break, rendering the line unusable. Utility Model Content

[0004] The purpose of this utility model is to provide an anti-pull buffer device for power cables to solve the above-mentioned problems, so as to solve the problem that in the prior art, power cables will sway significantly when encountering strong winds during the laying process, and the swaying will break when the swaying is severe, resulting in the line becoming unusable.

[0006] The buffer mechanism includes a mounting block disposed on the top of the stabilizing mechanism. The top of the mounting block is symmetrically provided with mounting cavities. A sliding rod is symmetrically fixed on the top between the two sides of the mounting cavity. A sliding plate slides symmetrically on the outer side of the sliding rod. A second clamping ring is fixed on the top of the sliding plate. A first spring is symmetrically fixed on one side of the sliding plate.

[0008] Preferably, one end of the first spring is fixed to one side of the mounting cavity, and the first spring is sleeved on the outside of the slide rod to facilitate the reset of the slide plate.

[0009] Preferably, one end of the connecting rod rotates inside the rotating groove, causing the connecting rod to deflect when the slide moves, and a drain outlet is provided through the bottom center of the mounting cavity.

[0010] Preferably, the bottom end of the second spring is fixed to the bottom of the mounting cavity, and the second spring is sleeved on the outside of the damper to facilitate the resetting of the connecting plate.

[0011] Preferably, the stabilizing mechanism includes a hanging ring sleeved on the outside of the hook, a steel cable fixed to the outside of the hanging ring, a first screw fixed to one end of the steel cable, a rotating cylinder screwed to the outside of the first screw, a knob fixed to the middle of the outside of the rotating cylinder, a fixing clamp connected to the outside of the steel cable, a connecting rod fixed to the top of the outside of the fixing clamp, a second screw screwed to the inside of the connecting rod, a rotating plate fixed to the top of the second screw, and a rotating cavity opened in the middle of the bottom of the mounting block.

[0012] Preferably, a baffle is fixed to one end of the first screw to prevent the first screw from detaching, and the rotating plate rotates inside the rotating cavity.

[0013] This utility model provides an anti-pull buffer device for power cables, which has the following beneficial effects:

[0014] 1. This application, through the setting of a buffer mechanism, places the cable into the second clamping ring, which is fixed by bolts. In windy weather, the cable sways, causing the second clamping ring to move, which in turn moves the sliding plate, compressing the first spring. At the same time, the connecting rod deflects, causing the mounting base to descend, which in turn lowers the connecting plate, compressing the second spring and the damper. Through the deformation of the first and second springs, the cable swaying is buffered. In conjunction with the damper, the potential energy of the spring is absorbed, ensuring the stability of the cable, avoiding violent shaking, and thus preventing cable breakage.

[0015] 2. This application, through the setting of a stabilizing mechanism, involves attaching a hanging ring to a hook, rotating a knob to drive a rotating cylinder to rotate, and the rotating cylinder being screwed to a first screw. Therefore, when the rotating cylinder rotates, the first screw moves inside the rotating cylinder, thereby tightening the steel cable and stabilizing the connection. Then, a fixing clamp is clamped onto the steel cable and secured with bolts. Afterwards, rotating the second screw adjusts the position of the second clamping ring, connecting the second clamping ring to the cable, thus synchronizing the cable and the steel cable. The steel cable is used to limit the cable's movement, thereby restricting the cable's sway amplitude and preventing violent swaying of the cable in windy weather, ensuring the stability of the cable.
