Description
Technical Field
The invention belongs to the field of aviation lifesaving, and particularly relates to a recovery system of a gun head of a parachute shooting gun.
Background
In the field of aviation lifesaving, an umbrella shooting gun and an umbrella shooting gun bullet both need to obtain various data through an external ballistic test, and the obtained data are compared with technical indexes of the data to finally determine whether the umbrella shooting gun or the umbrella shooting gun bullet meets the requirements of aviation lifesaving; in order to ensure that the external ballistic test is equivalent to the actual working condition, a test section is arranged between the position where the gun head flies out of the gun barrel and 500mm of the gun head flies, and the test section cannot perform any interference on the gun head. But when the gun head flies to the position outside 500mm, the gun head needs to be effectively recovered, the gun head is prevented from flying out to hurt people, the gun head is prevented from being damaged as much as possible, the reuse rate of the gun head is improved, and the test cost is saved.
The existing gun heads are recovered in two ways, one way is that after the gun heads fly out of a testing section, a recovery box with the length of 1.5m, the width of 1.5m and the height of 1.5m is placed in the flying direction of the gun heads, cotton yarns are filled in the recovery box, and the gun heads are intercepted and recovered through the cotton yarns in the recovery box; the other type is also recovered by a recovery box, but the recovery box is filled with rubber, and the gun head can be effectively intercepted and recovered after the gun head penetrates through the rubber.
Although the recovery method is simple, the outlet speed of part of the umbrella shooting gun is high, and when cotton yarn is recovered, the gun head is shot into and flies out deeply and is difficult to find; when the rubber is recycled, although the gun head is shot shallowly, the gun head is abraded greatly, one gun head can be used for 3 times on average and must be scrapped, and a hole left after the rubber is shot by the gun head cannot be repaired, so that the next test can be carried out after the position of the rubber is readjusted, and the test efficiency is low.
Disclosure of Invention
The invention aims to provide a recovery system of a gun head of an umbrella shooting gun, which adopts a flexible recovery method, firstly carries out energy transfer on the gun head, and then decelerates and recovers the gun head through a water braking technology, so that the damage of the gun head can be greatly reduced, and the test efficiency is improved.
The technical scheme adopted by the invention is as follows:
the utility model provides a penetrate umbrella rifle head recovery system, including being the straight line and downstream inclined's track, orbital upper reaches position is fixed with the barrel, the midstream is equipped with the recovery dolly, the upper portion of retrieving the dolly is for the recovery section of being used for accepting the rifle head, the lower part be with track complex running gear and wiper blade, it has flexible material to fill towards barrel open-ended first section in the recovery section, middle part slidable blocks to have the rubber slab, the end is the cavity and is equipped with the gas release hole, the wiper blade inserts the surface of water and more dark after the recovery dolly removes to the low reaches.
Further, one side of the wiper blade facing downstream is a protruding V-shaped surface.
Further, the initial position of the recovery trolley is located near the water surface.
Further, the rail is installed in the water tank through a raising layer, and the installation surface of the raising layer is inclined downstream.
Furthermore, the recovery device is suitable for recovering the gun heads in the tests of parachute shooting guns of lifesaving umbrellas, parachute stabilizing shooting guns and cover breaking guns.
Further, the track adopts double tracks.
Further, the track is inclined by 2 degrees.
Further, the flexible material is cotton yarn.
Further, the traveling mechanism is a pulley.
The invention has the beneficial effects that:
the system adopts a flexible recovery method, firstly energy is transferred to the gun head, then the gun head is decelerated and recovered through a water brake technology, the damage of the gun head can be greatly reduced, meanwhile, the test efficiency is improved, the gun head is ejected through the energy of an umbrella shooting gun bullet by the gun barrel, the gun head flies into the recovery trolley after the test is finished, the flexible material is driven to move forwards until the rubber plate is pushed to move forwards together, at the moment, air behind the rubber plate is compressed, and the gun head is slowly exhausted through an air exhaust hole to play a buffering role, meanwhile, the recovery trolley also can move forwards along a track until no relative displacement exists between the gun head and the recovery trolley, a certain speed and forward movement are formed until the recovery trolley moves to the downstream, the water scraping plate is inserted into the water surface and is deeper and deeper, and finally the resistance of the recovery trolley and the gun head is.
