Technical Field

The invention belongs to the technical field of fuze and fuze power supply release, and particularly provides a reliable micro-miniature fuze chemical power supply quick activation mechanism and a method thereof in the aspects of application of a chemical power supply in a fuze and fuze power supply integration technology.

Background

With the development of modern weapon systems, the mission to which the fuse is assigned is increasing, and therefore the concept of fuse is gradually perfected as: the control system utilizes target information, environment information, platform information and network information to detonate or ignite the warhead charge according to a preset strategy, can select an attack point, and gives an ignition instruction of a cruising or extended-range engine and damage effect information. In a further refined definition, the two words of 'information' are highlighted, and the utilization, processing, control and the like of the information need the fuse to be ensured by self-contained energy. Along with the complication of modern war, the traditional fuze power supply can not meet the requirements of modern fuze on volume, energy and the like gradually, and in order to meet the requirements of the modern fuze on rapidity and accuracy of information reception, the fuze power supply must be researched, so that the fuze power supply has the characteristics of quick activation, small volume, long service life, good adaptability under high-acceleration value and high-low temperature environment and the like, and the capability of hitting/fighting of the projectile is better reflected. The development of fuze power supplies also ensues. The first problem faced therewith was the investigation of the fuze power activation mechanism. The fuze and the fuze power supply activation mechanism need to have the characteristics of small size, quick activation and the like.

The traditional fuse and fuse power supply activation mechanisms mostly adopt firing pins and impact and activate initiating explosive devices by means of recoil force emitted by shells, so that the traditional activation mechanisms require larger axial space and have high dependence on working environment, and are only suitable for the condition of large overload, namely, the larger the recoil overload is, the higher the activation reliability is, and the lower the overload is, even the smaller the overload is, the initiating explosive devices cannot be reliably activated, so that the requirement for activating modern fuses and fuse power supplies is difficult to meet.

Disclosure of Invention

Aiming at the defects of large occupied space, high overload, slow perception to environment excitation, large dependence on working environment and the like of a fuse power supply activation mechanism in the prior art, the invention provides a micro-miniature fuse chemical power supply quick activation mechanism and a method thereof. The specific technical scheme is as follows:

a microminiature fuse chemical power supply rapid activation mechanism comprises an external shell 1, an inertia spring 2, a buffer spring 3, an electrolyte bottle 4, an inner layer rigid support 5, an upper safety ball 6, an inertia ring 7, a mass block 8 and a lower safety ball 9;

the inner layer rigid support 5 is fixedly connected with the shell 1 through a limiting groove; the inertia spring 2 is arranged between the shell 1 and the inner layer rigid support 5; the inertia ring 7 is connected with the inertia spring 2 and pre-tightens the inertia spring 2; circular clamping grooves are respectively formed in two sides of the upper parts of the inner-layer rigid support 5 and the mass block 8, and the inner-layer rigid support 5 and the mass block 8 are connected through an upper safety ball 6 and a lower safety ball 9; the electrolyte bottle 4 is fixed at the bottom of the mass block 8; the buffer spring 3 is fixed in the inner side clamping groove of the shell 1;

the activation mechanism further comprises a chemical cell reactor which is arranged around the buffer spring 3;

the shell 1 is a cylindrical rigid outer shell;

the electrolyte bottle 4 is filled with electrolyte.

A method for quickly activating a chemical power supply of a micro fuse uses the quick activation mechanism of the chemical power supply of the micro fuse, and comprises the following steps:

step 1: the inertia ring 7 is used as an environment sensing excitation element, and the inertia spring 2 is pre-tightened through the inertia ring 7;

step 2: after the external environment excitation meets the excitation requirement, the inertia ring 7 starts to press the inertia spring 2 to move downwards, when the inertia ring 7 moves to a preset position, the limit of the inertia ring 7 on the upper safety ball 6 and the lower safety ball 9 is sequentially released, the upper safety ball 6 and the lower safety ball 9 are separated from the limiting groove of the inner-layer rigid support 5, and the limit of the upper safety ball 6 and the lower safety ball 9 on the mass block 8 is further released;

and step 3: the mass block 8 and the electrolyte bottle 4 start to move downwards, the electrolyte bottle 4 starts to press the buffer spring 3 when reaching a preset position, the electrolyte bottle 4 is broken through the extrusion of the mass block 8 and the buffer spring 3, the electrolyte is released to react with the chemical battery reactor to release electric energy, and then subsequent electric initiating explosive devices such as a lightning tube are activated.

The perfect combination between the activation device of the fuze power supply and the chemical power supply of the micro-miniature fuze chemical power supply quick activation mechanism becomes the key for the success of the design, generally, if the energy released by the fuze power supply is large enough, the space size of a chemical battery reactor and a glass bottle for containing electrolyte is increased, and as a result, the size of the whole activation mechanism is increased. Therefore, it is necessary to comprehensively consider the relationship between the size and the discharge energy of the chemical battery according to the actual use of the activation mechanism.

Compared with the prior art, the micro fuse chemical power supply quick activation mechanism and the method thereof have the advantages that:

the mechanism combines and integrates an activation mechanism of a fuse and a fuse power supply, and the combination of an inertia ring and an inertia spring can sensitively sense the excitation of an external environment; the combination of the upper safety ball, the lower safety ball and the mass block of the bottle breaking mechanism well solves the service processing problem of the activation mechanism; the buffer spring and the mass block of the bottle breaking mechanism arranged inside the cylindrical outer shell effectively solve the problem of large recoil required by activating a chemical power supply of the fuze in the prior art.

The activation mechanism of the invention adopts the inertia ring and the inertia spring to sense the excitation of the external environment, and is perfectly combined with a chemical battery discharge system, thereby greatly reducing the space ratio occupied by the fuse activation mechanism and a power supply and having the characteristic of quick activation without depending on the working environment.

The size of the activation mechanism and the release energy of the fuse power supply can be flexibly designed according to the type of the electric initiating explosive device, the application range is wide, and the activation mechanism is suitable for various types of electric initiating explosive devices, such as lightning tubes and the like.

Fourthly, the activation mechanism has the advantages of high activation speed, simple and convenient use and good realizability.
