Protection device for combat vehicle

Abstract

Disclosed herein is a protective device for a combat vehicle. The protective device includes a net which protects the combat vehicle from a rocket bomb, and net support assemblies which are provided to install the net on the combat vehicle. Each net support assembly includes a net fixing unit which is coupled to a corresponding one of intersection portions of the net, a vehicle body mounting unit which is mounted to the combat vehicle, and a spacing unit which connects the net fixing unit to the vehicle body mounting unit. The protective device further includes a distance adjuster which adjusts the distance between the net and the vehicle body, a shock absorber which absorbs impact, a protective member which is provided to reduce friction between the rocket bomb and the net strand, and a rocket bomb removal assembly which is installed on each intersection portion of the net.

1 . A protective device for a combat vehicle, comprising:
 a net protecting the combat vehicle from a rocket bomb; and   a plurality of net support assemblies provided to install the net on the combat vehicle, each of the net support assemblies comprising: a net fixing unit coupled to a corresponding one of intersection portions of the net; a vehicle body mounting unit mounted to the combat vehicle; and   a spacing unit connecting the net fixing unit to the vehicle body mounting unit so that a distance is maintained between the net and a vehicle body of the combat vehicle.   
     
     
         2 . The protective device as set forth in  claim 1 , wherein the net fixing unit comprises:
 a fixing body having a plurality of fixing slots into which the corresponding intersection portion of the net is inserted; and   a fixing cover coupled to the fixing body so that the intersection portion of the net that has been disposed in the fixing body is fixed to the fixing body.   
     
     
         3 . The protective device as set forth in  claim 1 , wherein the spacing unit comprises a distance adjuster adjusting the distance between the net and the vehicle body. 
     
     
         4 . The protective device as set forth in  claim 3 , wherein the distance adjuster comprises:
 a left-handed threaded part provided at a side adjacent to the vehicle body mounting unit;   a right-handed threaded part provided at a side adjacent to the net fixing unit; and   a rotary body having an internal thread so that both ends of the rotary body are respectively threaded over the left-handed threaded part and the right-handed threaded part.   
     
     
         5 . The protective device as set forth in  claim 1 , wherein the spacing unit comprises a shock absorber absorbing shock when the rocket bomb is caught by the net. 
     
     
         6 . The protective device as set forth in  claim 5 , wherein the shock absorber comprises a coil spring coupled at a first end thereof to the net fixing unit and at a second end thereof to the vehicle body mounting unit. 
     
     
         7 . The protective device as set forth in  claim 1 , further comprising:
 a protective member provided around each of net strands of the net to reduce friction between the net stand and the rocket bomb.   
     
     
         8 . The protective device as set forth in  claim 7 , wherein the protective member comprises a coil spring wound around the net strand. 
     
     
         9 . The protective device as set forth in  claim 1 , further comprising:
 a rocket bomb removal assembly provided on each of the intersection portions of the net, the rocket bomb removal assembly having first intersection support points supporting net strands of the net that are brought into close contact with a circumferential outer surface of the rocket bomb and are changed into a shape of a circle when the rocket bomb moves forwards after having been caught by the net, and second intersection support points supporting the net strands that are brought into close contact with the circumferential outer surface of the rocket bomb and are changed into a shape of a circle when the rocket bomb is moved backwards by a reaction of the net, wherein a diameter of the circle formed by the net strands that are supported on the second intersection support points and have changed in shape is greater than a diameter of the circle formed by the net strands that are supported on the first intersection support points and have changed in shape.   
     
     
         10 . The protective device as set forth in  claim 9 , wherein the rocket bomb removal assembly comprises:
 a removal body disposed outside the net, the removal body comprising support parts extending predetermined lengths in directions in which the corresponding net strands of the intersection portion extend, each of the support parts having a support depression into which the corresponding net strand of the intersection portion of the net is inserted, so that the support parts support the corresponding net strands at the outside of the net; and   a removal cover disposed inside the net and coupled to the removal body, the removal cover covering the intersection portion of the net such that the net strands that are disposed in the support depressions of the removal body are exposed,   wherein the first intersection support points are formed on distal ends of the respective support parts of the removal body, and the second intersection support points are formed at respective beginnings of portions of the net strands exposed outside the removal cover.   
     
     
         11 . The protective device as set forth in  claim 9 , wherein the rocket bomb removal assembly comprises:
 a removal body disposed outside the net, the removal body having support depressions extending predetermined lengths in directions in which the corresponding net strands of the intersection portion extend, so that the net strands of the intersection portion are inserted into the respective support depressions such that the removal body supports the net strands at the outside of the net, with an inclined surface formed on a circumferential outer surface of the removal body, the inclined surface being reduced in diameter with respect to a direction in which the rocket bomb moves forwards; and   a removal cover disposed inside the net and coupled to the removal body, the removal cover covering the intersection portion of the net such that the net strands that are disposed in the support depressions of the removal body are exposed outside,   wherein the first intersection support points are formed at respective junctions between ends of the support depressions and the inclined surface, and the second intersection support points are formed at respective beginnings of portions of the net strands exposed outside the removal cover.   
     
     
         12 . The protective device as set forth in  claim 3 , wherein the spacing unit comprises a shock absorber absorbing shock when the rocket bomb is caught by the net.
