Electromagnetic inertial composite rotor-type isolating mechanism

Abstract

The invention discloses an electromagnetic inertial composite rotor-type isolating mechanism and belongs to the technical field of fuse safety mechanisms. The isolating mechanism comprises a body provided with a rotor hole, and a rotor embedded into the rotor hole in a sleeved mode. Holes for containing an electromagnetic pin push device, an inertial safety component, a lock pin, a converting switch, a fire transmitting component, an explosion transmitting component and the like are formed in the rotor and the body. By preferably selecting the structure components and optimizing the hole positions, the isolating mechanism is provided with a large isolation removal rotary angle, the states of the isolating mechanism can be accurately recognized and fed back, and it is ensured that the isolating mechanism can be locked at the states under all the states. According to the electromagnetic inertial composite rotor-type isolating mechanism, through the arrangement, on the one hand, safety of the mechanism under the safe state is ensured, alignment of the detonating sequence under the due-out condition is ensured, and the detonating efficiency is greatly promoted; and on the other hand, through application of the components such as the converting switch, the states of the isolating mechanism can be effectively recognized and fed back to a control system, and thus safety and the detonating efficiency of the isolating mechanism can be further promoted.

Description

technical field [0001] The invention belongs to the technical field of fuze insurance mechanisms, and in particular relates to an electromagnetic-inertia composite rotor isolation mechanism. Background technique [0002] Explosives are a general term for disposable components and devices that contain gunpowder or explosives, which burn or explode after being stimulated by the outside world to ignite gunpowder, detonate explosives, or perform mechanical work. An isolation mechanism is usually set in the pyrotechnics, and its function is to isolate the sensitive pyrotechnic elements in the explosion sequence from the next-level pyrotechnic elements at ordinary times, so as to ensure that the fuze does not ignite when the pyrotechnics accidentally act in advance, thereby avoiding Ammunition exploded prematurely, endangering the safety of personnel and equipment. [0003] The safety of the fuze involves the whole life cycle of the fuze, such as demonstration, design, manufactur...

AI Technical Summary

Problems solved by technology

First of all, when the safety of the isolation mechanism is released and the movement is in place, the isolation mechanism does not have a locking function. In the vibration environment, it is easy to cause the isolation mechanism to be misplaced, and eventually lead to incomplete alignment of the explosion sequence; secondly, the two-stage safety of the horizontal rotor type isolation mechanism If the components are misplaced, the size of the mechanism will be larger and the space utilization will be unreasonable; thirdly, the existing horizontal rotor type isolation mechanism usually cannot accurately identify and display the state of the isolation mechanism, which is not conducive to the operator to judge the state of the isolation mechanism , indirect security risks

The above-mentioned defects limit the application of the horizontal rotor type isolation mechanism to a certain extent, have certain influence on the safety and practicability of the isolation mechanism, and cannot fully satisfy the safe use of the fuze.
