Projectile recovery chamber

Abstract

A chamber for the recovery of projectiles, or a bullet trap, which uses a gel having rheopectic properties in order to stop the bullet and which also uses a gel recirculation system in order to increase viscosity such that it stops the passage of the bullet. In addition, the recirculation system attracts the bullet towards the lowest part of the chamber and directs same towards a basket type filter from where the bullet is recovered. The dimensions of the projectile recovery chamber are such that it is easy to transport and the chamber includes a raising mechanism that can be used to adjust the height of the chamber according to the height of the shooter, as well as including a positioning device and a distributed logic control system for stopping and starting a recirculation pump.

The invention having been broadly described, I claim the content of the following claims as my property: 
     
         1 . A projectile recovery chamber, wherein the chamber comprises a modular cylindrical body, a projectile recovery system, a height-adjustment mechanism that maintains the front end at a greater elevation than the rear end, a fluid-recirculation system and wherein the chamber includes means for stopping and recovering projectiles; characterized in that the means for stopping and recovering projectiles is a non-Newtonian fluid with rheopectic properties. 
     
     
         2 . The projectile recovery chamber as claimed in  claim 1 , wherein the fluid is a gel with rheopectic properties, in which the viscosity thereof increases in proportion to the shear force applied. 
     
     
         3 . The projectile recovery chamber as claimed in  claim 1 , wherein the projectile recovery chamber has a shock-absorbing system that absorbs the firing energy and allows the chamber to move over a metallic platform and to return to its initial position. 
     
     
         4 . The projectile recovery chamber as claimed in  claim 3 , wherein the chamber has a pumping system that extracts the fluid and returns it to the chamber, generating a high shear force in the fluid. 
     
     
         5 . The projectile recovery chamber as claimed in  claim 4 , wherein, upstream of the pump, there is a basket-type filter for trapping the fired projectiles. 
     
     
         6 . A projectile recovery chamber for stopping and trapping projectiles fired by a firearm, wherein the chamber comprises a modular cylindrical body, a means for retaining fired projectiles, a projectile recovery system, means for adjusting the height of the cylindrical body at the front end thereof, a control panel, a weapon-positioning system, a basket for trapping the shells of the fired projectiles, means for moving the chamber, characterized in that the means for retaining the fired projectiles is a gel with rheopectic properties and in that the chamber has a pump that has a basket-type filter coupled to a hydraulic system that extracts the fluid from the chamber and returns it, generating a constant high force. 
     
     
         7 . The projectile recovery chamber as claimed in  claim 6 , wherein the projectile recovery chamber has a shock-absorbing system that absorbs the firing energy and allows the chamber to move over a metallic platform and to return to its initial position. 
     
     
         8 . The projectile recovery chamber as claimed in  claim 6 , wherein the weapon-positioning system is a magnetic centering device in the form of a “V”, on which the barrel of the weapon to be fired is placed. 
     
     
         9 . The projectile recovery chamber as claimed in  claim 6 , wherein the fired projectile is sucked, together with the rheopectic gel, from the bottom of the chamber by the self-aspirating pump and trapped in the basket-type filter from where it can be easily removed. 
     
     
         10 . The projectile recovery chamber as claimed in  claim 6 , wherein the weapon-positioning system has a position sensor that actuates the pump when the weapon is placed on a weapon-positioning system and stops the functioning of the pump when the weapon is removed. 
     
     
         11 . The projectile recovery chamber as claimed in  claim 10 , wherein the chamber has a sensor that activates an alarm to indicate that the test is starting. 
     
     
         12 . The projectile recovery chamber as claimed in  claim 11 , wherein the pump, the presence sensor and the alarm are connected to a PLC that controls the functioning of the chamber. 
     
     
         13 . The projectile recovery chamber as claimed in  claim 2 , wherein the projectile recovery chamber has a shock-absorbing system that absorbs the firing energy and allows the chamber to move over a metallic platform and to return to its initial position. 
     
     
         14 . The projectile recovery chamber as claimed in  claim 7 , wherein the weapon-positioning system is a magnetic centering device in the form of a “V”, on which the barrel of the weapon to be fired is placed. 
     
     
         15 . The projectile recovery chamber as claimed in  claim 7 , wherein the fired projectile is sucked, together with the rheopectic gel, from the bottom of the chamber by the self-aspirating pump and trapped in the basket-type filter from where it can be easily removed. 
     
     
         16 . The projectile recovery chamber as claimed in  claim 8 , wherein the fired projectile is sucked, together with the rheopectic gel, from the bottom of the chamber by the self-aspirating pump and trapped in the basket-type filter from where it can be easily removed. 
     
     
         17 . The projectile recovery chamber as claimed in  claim 1 , wherein the chamber has a sensor that activates an alarm to indicate that the test is starting. 
     
     
         18 . The projectile recovery chamber as claimed in  claim 6 , wherein the chamber has a sensor that activates an alarm to indicate that the test is starting.
