Projectile recovery device

Abstract

The invention relates to a projectile recovery device, in particular to a device for buffering and storing a projectile horizontally shot by an ejection device within a short distance. Compared with the prior art, the specific deep cavity form of a common tire and high elasticity, large damping and impact resistance of a rubber, cord thread and steel wire composite material are utilized, front buffering and springback blocking can be efficiently carried out on an incoming high-speed projectile body, a narrow deep-hole type buffering and recycling space is formed by combining the serially-connected tires, a rebounding path and a rebounding stroke of a projectile can be effectively limited, the buffer efficiency and safety can be further improved, the service life of the device can be further prolonged by optimizing filling of buffer materials in a tire cavity and a net bag in the scheme, and the whole scheme is compact in structure, short in recovery stroke, high in recovery efficiency, controllable in projectile rebounding and suitable for being used in the narrow space.

Description

technical field [0001] The invention relates to a projectile recovery device, in particular to a device for buffering and storing projectiles shot horizontally by an ejection device within a short distance. Background technique [0002] In the research and development process of launching devices such as drones and fire extinguishing bombs, it is often necessary to debug and test the performance of the launching devices through simulated loads. Due to the constraints of the test environment, it is usually necessary to buffer and store the high-speed injection simulated load within a certain space to avoid damage to the test site and related equipment and facilities. In practice, this type of recovery device either adopts a grid frame or a frame method. The former uses a safety net to buffer and recover the simulated load as a projectile, and the latter uses the buffer pad in the frame to buffer and recover the simulated load. Generally speaking, the space frame method takes...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is that the space of the grid frame is large, the rebound path of the projectile is not easy to control, and the frame method is bulky, heavy, and the impact of recovery is large, and the recovery pad is easy to be damaged, especially when the space of the test site is small, The use of both of the above methods is restricted
