Abstract

The invention discloses a self-starting thermal power generation device comprising an electrical trigger and a thermal power generation element which are electrically connected with each other, wherein the electrical trigger is connected with a fire extinguishing system; the thermal power generation element comprises an anode, a cathode and a molten salt electrolyte arranged between the anode and the cathode as well as an external shell, and the thermal power generation element is arranged in a fire monitoring field. The self-starting thermal power generation device can be normally started without a power supply or after power failure, has the advantages of low temperature resistance, moisture resistance, simple structure, reliable action, high sensitivity, no false alarm and the like, and is suitable for various electrical start type fire extinguishing systems due to a large quantity of applicable fire extinguishing agent mediums.

Description

technical field [0001] The invention belongs to the technical field of fire protection, and in particular relates to a self-starting device for heating and generating electricity. Background technique [0002] With the improvement of people's awareness of fire safety, more and more fire extinguishing devices are used, so people pay more and more attention to the safety and reliability of fire extinguishing devices. Among the compressed ultrafine dry powder fire extinguishing devices, there are two main ways to start these fire extinguishing devices: [0003] One is to start with a heat-sensitive wire, which is a linear structure made of temperature-sensitive spontaneous combustion material and connected to a fire extinguishing device. In the event of a fire, the heat-sensitive wire located in the protection area will spontaneously ignite when it reaches a certain temperature , Use the heat generated by spontaneous combustion to activate the fire extinguishing device. The d...
