[0002] Detonating cord is a special device used to transmit explosion waves. It is widely used in military, mining, construction, engineering blasting and other fields. The main function of detonating cord is to transmit explosion waves through the explosive material inside it to detonate other explosives or blasting devices connected to it. The failure of detonating cord is caused by many factors, including but not limited to physical damage, chemical decomposition, environmental impact, etc. In order to ensure the safety and reliability of detonating cord, a series of measures need to be taken to prevent its failure.

[0003] Existing detonating cords are usually wound on a winding wheel and then tied with a rope. When they are needed, the whole bundle of detonating cords is taken to the place where they are needed. Current detonating cords are usually stored exposed to the outside and do not have a sealed and moisture-proof structure. When used in a humid environment, moisture can easily come into direct contact with the detonating cord, causing the detonating cord to fail, shortening its service life, and making it inconvenient to use.

[0004] Therefore, it is necessary to design a coal mine safety detonating cord failure prevention device suitable for use in humid environments that can store and protect detonating cords, prevent moisture, prevent detonating cord failure, is easy to use, has good sealing, and extends the service life of detonating cords. Summary of the invention
