A shock-absorbing pole

Abstract

The invention belongs to the technical field of transmission lines and particularly relates to a shock-absorbing electric pole which comprises an electric pole, a base, a first shock-absorbing plate,a second shock-absorbing plate and a sleeve. The electric pole is vertically fixed to the base, a plurality of first screws are fixed to the base around the electric pole, and a plurality of second screws fixed to the base are further disposed between the first screws and the electric pole. The sleeve sleeves the electric pole. The first shock-absorbing plate and the second shock-absorbing plate sleeve the sleeve. The upper ends of the first screws penetrate the first shock-absorbing plate and then are sleeved with nuts and tightened; the upper ends of the second screws sequentially penetratethe first shock-absorbing plate and the second shock-absorbing plate upwards and then are sleeved with nuts and tightened; and portions of the second screws between the first shock-absorbing plate andthe second shock-absorbing plate are sleeved with damping springs. The shock-absorbing electric pole is long in service life, is not overturned or broken and has the capability of self-restoration after an instant tilt.

Description

technical field [0001] The invention belongs to the technical field of power transmission lines, and in particular relates to a shock-absorbing electric pole. Background technique [0002] Electric poles are bridges for electricity, allowing electricity to be transported to various places. The common electric poles we have are wooden poles and concrete poles. They are of different heights. There are many general types of poles, such as: concrete poles, concrete poles, poles made of concrete and steel bars or steel wires. 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 underg...

Problems solved by technology

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.
