Shape memory alloy fire hydrant protection fence

Abstract

The invention discloses a shape memory alloy fire hydrant protection fence. The shape memory alloy fire hydrant protection fence comprises a plurality of protection pipes, wherein four protection pipes form a rectangular closed ring support. A heating device is arranged on the rectangular closed ring support and connected to a power source through a circuit. The lower portions of four corners of the rectangular closed ring support are connected with the protection pipes respectively, and the lower ends of the protection pipes are fixed to the ground through iron plates; the innermost layer ofeach protection pipe is a shape memory alloy tube, and the exterior of each shape memory alloy tube is a reinforcing layer, the exterior of each reinforcing layer is a heat preservation layer or a heat insulation layer, the exterior of each heat preservation layer or each heat insulation layer is provided with a stainless steel layer, and the exterior of each stainless steel layer is coated with apaint layer. The shape memory alloy tubes can be heated, and the protection fence damaged by mechanical impact, rain water impact, earthquake damage and other factors is repaired. The raw materials used are cheap, the mechanical property is good, heat processing is easy, phase change hysteresis is wide, and the thermal conductivity is great.

Description

technical field [0001] The invention relates to a fire hydrant protective fence, in particular to a shape memory alloy fire hydrant protective fence, which has a certain self-repairing ability. Background technique [0002] The fire hydrant is an important tool for fire fighting and emergency rescue for the fire department. Its deficiency and damage will seriously affect the effect of fire protection. According to relevant regulations, fire hydrants must be installed in public places such as streets, roads, and communities, enterprises and institutions. However, in real life, due to the lack of fire safety awareness of some units and individuals, fire hydrants are often damaged intentionally or unintentionally, either lacking "arms" or missing "legs", and some fire hydrants are surrounded by vehicles, stalls or sundries. The water is not leaking, and it cannot be connected at all; according to incomplete statistics, there are dozens of incidents where fire hydrants on the m...

Problems solved by technology

However, in real life, due to the lack of fire safety awareness of some units and individuals, fire hydrants are often damaged intentionally or unintentionally, either lacking "arms" or missing "legs", and some fire hydrants are surrounded by vehicles, stalls or sundries. Watertight and impossible to connect at all; according to incomplete statistics, there are dozens of incidents where fire hydrants are broken off next to main streets every year

Once a fire breaks out, these fire hydrants will not be able to play their due role, causing heavy losses to people's lives and property
