Anti-seismic pole

Abstract

The invention discloses an anti-seismic pole which comprises a pole main body (10), a moisture-proof shell and an anti-seismic mechanism arranged in the moisture-proof shell, wherein the anti-seismic mechanism comprises a support base (1) and a damping structure; an air spring (9) is arranged between the damping structure and the support base; a pressure sensing module (21) and a wireless sending module (22) are arranged in the air spring (9); the wireless sending module (22) is wirelessly communicated with a wireless receiving module in a remote central control chamber; an output end of the wireless receiving module is electrically connected with a control module; the output end of the control module is electrically connected with an alarming module. According to the invention, a disc spring set and an air spring buffering component are arranged between the support base and the damping base and a damping spring is arranged between a connecting rod and a cover plate, so that the rigid damage of transverse wave and longitudinal wave of earthquake to the pole can be effectively prevented.

Problems solved by technology

[0002] At present, the pole design and structural safety and stability construction of the 35KV and below power transmission and distribution lines of the power grid are relatively weak. The poles for power transmission and wiring are all set with thick cylinders at the bottom and brackets at the top, which are tree-shaped at high altitudes. , used to erect wires and cables, the bottom end of which is connected by bolts to the foundation that is simply laid underground, but this traditional way of rigidly fixing the pole to the ground is difficult to resist the vibration of the foundation or the occurrence of earthquake disasters. When an earthquake occurs, it often causes Foundation cracking and uneven settlement, etc.; when natural disasters such as strong winds, heavy snow, heavy rain, and ice cover occur, the poles will be tilted and overturned like a "domino" effect, and the entire section will even be broken and damaged. The destruction of the area and the power outage accident seriously endanger the power safety and residents' production and living electricity, and bring immeasurable losses to the national economy.

On August 14, 2013, a tornado hit Pushi Town, Luxi County, Xiangxi Autonomous Prefecture. After the tornado, the roofs of Neiwa houses in the town were overturned, and the utility poles collapsed in rows and fell on the roofs of residents or trees. More than 5 The 10 kV line was affected by the disaster, affecting nearly 100,000 residents in four villages and towns for production and living electricity. However, the current common method is to prefabricate concrete at the base, and then connect the bottom of the pole through the flange. If the concrete base is small It is easy to settle, if it is very large, it will waste a lot of resources, and the flange connection method is easy to break in the case of strong wind, vibration, etc., and there is still a big safety hazard. Therefore, how to design a new type of pole structure to make it easier to fight disasters ability greatly improved

The disadvantage of this structure is that the connection between the pole and the base is still rigid, and the earthquake resistance is not strong in the face of the shear wave and longitudinal wave of the earthquake

The disadvantage of this structure is: the structure is complicated, and the installation process is time-consuming and laborious
