A protective box for a vehicle-mounted fire extinguisher

Abstract

The invention relates to the technical field of fire safety, and discloses a vehicle-mounted fire extinguisher protection box, including a base, a support spring is fixedly installed in the middle of the upper surface of the base, and a tray is fixedly installed at the other end of the support spring, and the tray There is a circular groove in the middle of the upper surface. In the present invention, a permanent magnet is arranged inside the supporting spring, and cutting coils are arranged on both sides at the same time, the mechanical energy of vibration is converted into electric energy by cutting the motion of the magnetic induction line, and then the current is changed by changing the turn ratio of the transformer coil. The electrolytic cell converts electrical energy into chemical energy and stores it, and then transfers the potential energy to P-type semiconductors and N-type semiconductors through the thermoelectric second effect, so that when the direction of the current at the axis is N-P, the inner end plate absorbs heat and stays away from the The current direction at the axial direction is P-N, and the outer end plate releases heat, so as to achieve the effect of protecting the internal cooling of the box and avoiding the explosion of the dry powder fire extinguisher when the temperature is too high.

Description

technical field [0001] The invention relates to the technical field of fire safety, in particular to a protective box for a vehicle-mounted fire extinguisher. Background technique [0002] The vehicle-mounted fire extinguisher is a kind of fire extinguisher that is installed on the car and is specially used for car fire extinguishing. The common vehicle-mounted fire extinguishers are divided into dry powder fire extinguishers, carbon dioxide fire extinguishers, and aqueous film-forming foam fire extinguishers. Most of the fire extinguishers equipped with vehicles are dry powder fire extinguishers. [0003] Because the car will vibrate during driving, the vehicle-mounted dry powder fire extinguisher will also vibrate back and forth after installation. The usual dry powder fire extinguisher will be prone to compaction when it is in a vibrating environment for a long time, making the fire extinguisher invalid. At the same time, the vehicle in summer When not in use, the environ...
