Missile-borne thermal battery activation device

Abstract

The invention discloses a missile-borne thermal battery excitation device which comprises a body, a thermal battery arranged on the body, a firing mechanism, two sets of two-degree-of-freedom recoil safety mechanisms and two sets of quasi-fluid recoil safety mechanisms. Each two-degree-of-freedom recoil safety mechanism comprises an upper inertia cylinder, an upper inertia spring, a first safety ball, a lower inertia cylinder, a lower inertia spring, a bottom cover, a blocking block, an inertia pin spring and an inertia pin; each quasi-fluid recoil safety mechanism comprises a bottom plug, a large inertia spring, a quasi-fluid, a piston, a second safety device and a third safety ball; the firing mechanism is arranged in a cavity of the body; the upper inertia cylinder, the upper inertia spring, the lower inertia cylinder, the lower inertia spring and the bottom cover are sequentially connected in series; the inertia pin, the inertia pin spring and the blocking block are sequentially connected in series; the piston, the quasi-fluid and the bottom plug are sequentially connected in series; the first safety ball is located in a blind hole between the upper inertia cylinder and a V-shaped groove in the outer wall of the inertia pin; the second safety ball is clamped with the firing mechanism; and the third safety ball is clamped with the firing mechanism. The device is good in safety.

Description

technical field [0001] The invention belongs to the technical field of pyrotechnic batteries, in particular to an activation device for bomb-loaded thermal batteries. Background technique [0002] With the rapid development of computer technology, detection and guidance technology and artificial intelligence technology, modern weapons and equipment have achieved unprecedented development. These high-tech weapons and equipment have promoted the rapid development of thermal battery technology, making the application of thermal batteries more and more extensive. There are two commonly used thermal battery activation methods. The first is to activate the thermal battery by relying on external power supply or high-pressure gas. The volume is too large and the structure is bloated; the second is to use a hole-shaped structure to connect the firing pin to the safety pin.

Problems solved by technology

There are two commonly used thermal battery activation methods. The first is to activate the thermal battery by relying on external power supply or high-pressure gas. The volume is too large and the structure is bloated; the second is to use a hole-shaped structure to connect the firing pin to the safety pin. The problem with this method is that the force required to remove the safety pin is relatively large, and it is not suitable for low launch overload environments. In addition, it is time-consuming and labor-intensive to align the head of the safety pin with the hole where the firing pin is inserted during the assembly process. At the same time, the firing mechanism takes up a lot of space and is heavy.
