Fire extinguishing device with time delay function

Abstract

According to a fire extinguishing device with a time delay function, on one hand, a main blasting fuse is a low-speed blasting fuse, the surface of the main blasting fuse is wrapped with protective blasting paper, the protective blasting paper can be moisture-proof tin foil gummed paper, and the protective blasting paper can conduct twisting and blasting protection on the main blasting fuse, so that the main blasting fuse is prevented from fast burning and fire crossing and is moisture-proof; and therefore the fire extinguishing device has a delayed explosion function; and on the other hand, a standby lead is further included, one end of the standby lead is located on the outer side of a center cylinder and extends in the mode of being attached to the top wall of the center cylinder, the other end of the standby lead penetrates through the top wall of the center cylinder and then is connected with a pyrotechnic composition, the position of the standby lead and the position of the main blasting fuse are staggered, two lines for igniting the pyrotechnic composition of the standby lead and the main blasting fuse are formed, the two lines are not liable to interfere with each other, when one line fails and cannot be ignited, the other line can also achieve the ignition function, and the problem that the lines cannot be ignited when put into a fire source is solved.

Description

technical field [0001] The invention belongs to the technical field of fire-fighting equipment, and in particular relates to a fire-extinguishing device, in particular to a fire-extinguishing device with a delay function, which is suitable for fighting fires in forests, forests, grasslands, enterprises and households. Background technique [0002] The loss that fire causes to people is extremely heavy, therefore requires fire extinguishing equipment to be able to extinguish the fire in time, rapidly and safely. Therefore, it seems that fire extinguishing devices are used more and more in the field of fire protection, and are generally used in unattended areas or areas with few people. When a fire occurs, the fire signal is transmitted to the fire extinguishing device through the external thermal wire, and the fire extinguishing device sprays the fire extinguishing agent to the fire scene through the internal driving device to extinguish the fire. For example, certain temper...

AI Technical Summary

Problems solved by technology

However, the disadvantage of the above structure is that both the spare fuse and the pull-ring firing device are used to ignite the ignition fuse. When the ignition fuse has a problem and cannot be ignited, there may be a problem that the fire extinguishing device cannot be detonated when it is put into the fire source.
