Description

Technical Field

[0001] The utility model relates to the technical field of electric power towers, in particular to an earthquake-resistant electric power tower. Background Art

[0002] Power towers, also known as transmission and transformation line towers, are usually 25-40 meters high and are steel frame structures. Power towers are mostly built near outdoor power plants and distribution stations. They are important facilities in the power sector and an indispensable part of the power transmission system. They can overhead, protect and support wires.

[0003] The transmission lines are supported and fixed by power towers. However, if strong winds blow the power lines or the towers vibrate due to earthquakes, the power lines will swing back and forth. The transmission lines themselves have a certain weight, and the external force will cause a certain length of damage to the connection between the transmission lines and the power towers. In severe cases, the transmission lines may detach from the power towers, affecting the normal transmission of electricity. Utility Model Content

The rod 53 and the second threaded rod 54 are fixedly connected at one end thereof which is close to each other, and the outer surfaces of the first threaded rod 53 and the second threaded rod 54 are both threadedly connected with a clamping plate 52. By setting two clamping plates 52 and rotating the first threaded rod 53 and the second threaded rod 54, the first threaded rod 53 and the second threaded rod 54 will respectively drive one clamping plate 52 to move toward each other until the two clamping plates 52 completely clamp the transmission line, thereby auxiliary fixation can be performed between the hanging line end 4 and the transmission line, reducing the pulling on the connection between the hanging line end 4 and the transmission line when the transmission line is shaken by external force, thereby helping to prevent the transmission line from detaching from the power tower and ensuring the normal transmission of electric energy.

By providing the bearings 55, the friction between the first threaded rod 53 and the second threaded rod 54 and the auxiliary block 51 during rotation can be reduced, thereby making it easier to rotate the threaded rods; the ends of the first threaded rod 53 and the second threaded rod 54 that are away from each other are fixedly connected with an operating block 56, and the outer surface of the operating block 56 is provided with a protrusion. By providing the operating block 56, rotating the operating block 56 can drive the first threaded rod 53 and the second threaded rod 54 to rotate.

[0030] Reference Figure 2 and Figure 3As shown, the inner walls of the two clamps 52 are slidably connected with the same round rod 57, and the two ends of the round rod 57 are fixedly connected to one side of the two auxiliary plates.

[0033] Working principle: When the transmission line needs to be fixed, the rotating operating block 56 drives the first threaded rod 53 and the second threaded rod 54 to rotate. Under the limit of the round rod 57, the first threaded rod 53 and the second threaded rod 54 will respectively drive a clamping plate 52 to move toward each other until the rubber plate 58 on one side of the two clamping plates 52 completely clamps the transmission line, so that the hanging line end 4 and the transmission line can be auxiliary fixed, reducing the pulling on the connection between the hanging line end 4 and the transmission line when the transmission line is shaken by external force, which is helpful to prevent the transmission line from detaching from the power tower; when it is necessary to fix the connecting plate 22 and When fixing the support tower body 1, the threaded pin 23 is inserted into the inner wall of the circular hole block 24, and the threaded pin 23 can limit the circular hole block 24.

The threaded pin 23 and the circular hole block 24 can be fixed, and then the connecting plate 22 and the support tower body 1 are fixed. The connecting plate 22 and the extension plate 21 can increase the support area between the support tower body 1 and the support surface, making the support tower body 1 more stable and improving the earthquake resistance of the power tower.
