Description

Short-range defense device

Technical Field

The invention belongs to the technical field of machinery, relates to a short-range defense device, and particularly relates to a non-rotary-pipe type multi-pipe multifunctional short-range defense device.

Background

At present, the known short-range defense device (the known short-range anti-missile warship system with dense missile curtains built at home and abroad) usually has an optimal interception zone of an anti-ship missile within 2-3 kilometers, when the flight speed of the anti-ship missile is faster and faster, the number of projectiles capable of being launched by a cannon in an effective interception zone is smaller and smaller, taking an '1130-type' near defense weapon system with a shooting speed of more than ten thousand per minute as an example for targets attacking by the anti-ship missile, in the effective interception zone, when the speed of the attacking missile reaches Mach 3, the successful interception of the attacking missile needs to launch about 400 projectiles within a reaction time of only two seconds, and under the speed, the '1130-type' near defense weapon system is difficult to guarantee the successful interception of the attacking targets. In the effective interception zone, the success probability of the short-range anti-pilot gun weapon system for intercepting the incoming missile is necessarily and directly reduced by reducing the number of the shot in unit time, and conversely, in the effective interception zone, the success probability of the short-range anti-pilot gun weapon system for intercepting the incoming missile is necessarily improved by increasing the number of the shot in unit time, and meanwhile, the interception time of the incoming target is shortened, so that the interception frequency of the short-range anti-pilot gun weapon system for intercepting the incoming target in the optimal interception zone is further increased. The currently disclosed active H/PJ-11 (1130) type approach defense system discloses a maximum firing rate of 11000 shots/minute. In order to achieve higher shooting speed, the H/PJ-11(1130 type) active near-defense gun adopts a Gattelin rotary tube type structure gun body driven by external power, 1 set of external power bullet supply system is arranged, a plurality of rotary launching tubes are arranged, each launching tube is provided with a percussion device, and each launching tube is launched once every time the firing device rotates one circle. The maximum firing speed of the H/PJ-11 type (1130 type) near-defence cannon is 11000 shots/minute, the firing speed is difficult to improve, ammunition types can not be switched according to different targets, the launching tube is easy to overheat during long-time work, and the launching tube rotating at high speed can generate centrifugal force on the launched shots during work, so that the shooting precision is reduced.

For a group of V-shaped concave lines 3 and arc firing pin plectrums 11, the highest point of the V-shaped concave lines 3 and the lowest point of the arc firing pin plectrums 11 are on the same longitudinal line, and the middle point of the straight line segment at the lowest point of the V-shaped concave lines 3 and the highest point of the arc firing pin plectrums 11 are on the same longitudinal line.

The working process is as follows: when the motor 1 is started, the speed reducer 25 transmits the torque of the motor 1 to the driving shaft 2, the driving shaft 2 rotates along with the torque, the arc-shaped firing pin poking piece 11 and the turbine cooling fan 15 rotate along with the driving shaft 2, and when the driving shaft 2 rotates, the V-shaped concave line 3 arranged on the driving shaft 2 drives the active trigger 7 to force the active trigger 7 to reciprocate up and down along the axial direction of the driving shaft 2 through the Z-shaped connecting rod 9 in sliding contact with the driving shaft. When the driving column 17 arranged on the surface of the active trigger 7 moves in a straight line section in the track groove 18 arranged on the bullet supply plectrum 6, the bullet supply plectrum 6 does not move, because one end of the first plate of the bullet supply plectrum 6 is fixed on one side of the outer surface of the internal toothed guide rail base 10 through the fourth bolt 35, the other end of the first plate of the bullet supply plectrum 6 is movably connected with the second plate through the first movable buckle 36, the second plate and the third plate of the bullet supply plectrum 6 are movably connected through the second movable buckle 37, the moving track of the driving column 17 is not changed, when the driving column 17 arranged on the surface of the active trigger 7 moves upwards in the track groove 18 arranged on the bullet supply plectrum 6 to an interval with radian at the top end of the track groove 18, the driving column 17 forces the side of the second movable buckle 37 at the lower end of the second plate to move towards the launching tube, and the grapple 22 also moves towards the launching tube 14, when the driving column 17 arranged on the surface of the active trigger 7 moves downwards in the track groove 18 arranged on the ammunition feed plectrum 6 and leaves the arc-shaped section at the top end of the track groove 18 arranged on the ammunition feed plectrum 6, the driving column 17 forces one side of the second movable buckle 37 at the lower end of the second plate to move towards the direction of the external ammunition feed system 19, at the moment, the grapple 22 also moves towards the direction of the external ammunition feed system 19, the active trigger 7 reciprocates up and down, the driving column 17 arranged on the surface of the active trigger 7 reciprocates up and down, the driving column 17 forces one side of the second movable buckle 37 at the lower end of the second plate of the ammunition feed plectrum 6 to reciprocate left and right, when the ammunition feed plectrum 6 reciprocates left and right, the grapple 22 also reciprocates left and right, and the distance of the reciprocating motion of the grapple 22 is the distance of.

The natural distance between the L-shaped firing pin 12 and the Z-shaped connecting rod 9 is 3-5mm smaller than the distance from the highest point of the V-shaped concave line 3 to the lowest point of the arc firing pin plectrum 11; when the active firing device moves to the highest point, the L-shaped firing pin can be ensured to enter the upper surface of the arc-shaped firing pin plectrum, when the active firing device moves downwards, the arc-shaped firing pin plectrum can be ensured to clamp the main L-shaped firing pin, when the driving shaft continues to rotate, the V-shaped concave line forces the active firing device to move downwards, the arc-shaped firing pin plectrum forces the L-shaped firing pin to move upwards, so that the first spring is compressed, when the active firing device moves to the midpoint of the lowest point of the V-shaped concave line, the part of the L-shaped firing pin extending out of the active firing device leaves the constraint of the arc-shaped firing pin plectrum, and at the moment, the L-shaped firing.

When the driving shaft 2 rotates to enable the active firing device 7 to move upwards to the highest point of the V-shaped concave line 3, the part of the L-shaped firing pin 12 extending out of the active firing device 7 moves upwards to the position corresponding to the lowest point of the arc-shaped firing pin plectrum 11 along with the active firing device 7, the driving shaft 2 continues to rotate, the active firing device 7 starts to move downwards, but the part of the L-shaped firing pin 12 extending out of the active firing device 7 already enters the lowest point of the arc-shaped firing pin plectrum 11 at the moment, and the L-shaped firing pin 12 cannot move downwards at the moment,

when the active trigger 7 moves downward, the protruding edge of the curved striker paddle 11 blocks the portion of the L-shaped striker 12 that extends out of the active trigger 7 and prevents the L-shaped striker 12 from moving downward. The L-shaped firing pin 12 moves towards the direction opposite to the moving direction of the active firing device 7 under the reverse force of the arc-shaped firing pin shifting piece 11, at the moment, a first spring 5 in the active firing device 7 is compressed, when a Z-shaped connecting rod 9 of the active firing device 7 moves to the center of the lowest point straight line section of the V-shaped concave line 3, the part of the L-shaped firing pin 12 extending out of the active firing device 7 is separated from the constraint of the arc-shaped firing pin shifting piece 11, at the moment, the L-shaped firing pin 12 moves downwards, the top end of the L-shaped firing pin 12 extends out of the thin end of the active firing device 7 to strike a bottom fire of the ammunition, as the downward striking force of the L-shaped firing pin 12 comes from the compressed first spring 5, in order to buffer the excessive inertia of the L-shaped firing pin 12 caused by the first spring 5 and not to enable the L-shaped firing pin 12 to insufficiently strike the bottom fire.

When the active trigger 7 moves from the lowest point to the highest point (finishes a triggering action), the shell withdrawing grapple 20 enables the empty cartridge shell to move upwards, when the active trigger 7 moves to the highest point and leaves the high point, namely, the top end of the active trigger 7 is touched to leave from the signal generator 21, the signal generator 21 sends a signal for supplying the cartridge to the fixed cartridge supply belt 13 to the external cartridge supply system 19, and then the external cartridge supply system 19 carries out the action of supplying the cartridge to the fixed cartridge supply belt 13 (when the top end of the active trigger 7 is touched to leave from the signal generator 21, the external cartridge supply system 19 supplies the cartridge to the fixed cartridge supply belt 13 once, the top end of the active trigger 7 is not touched from the signal generator 21, and the external cartridge supply system 19 prohibits the cartridge supply to the fixed cartridge supply belt 13); meanwhile, the driving column 17 on the active firing device 7 moves to the arc-shaped position at the top end of the track groove 18, the moving track of the driving column 17 is not changed, the arc-shaped section of the driving column 17 at the top end of the track groove 18 moves to force the movable part of the bullet-supplying poking sheet 6 to move towards the launching tube 14, so that the grapple 22 on the ammunition feed plectrum 6 moves towards the direction of the launching tube 14, then the grapple 22 enables new ammunition 33 in the fixed ammunition feed belt 13 to enter the launching tube 14 through the ammunition inlet 31, the new ammunition 33 enters the launching tube 14 through the ammunition inlet 31 and simultaneously squeezes the empty cartridge shell to leave the launching tube 14 through the shell throwing hole 31, when the active trigger 7 moves towards the lowest point from the highest point, at this point, new ammunition 33 has entered the launch tube 14, driving the post 17 out of the arc segment at the top of the tracking slot 18, which in turn forces the catch 22 to move in the direction of the outer feed system 19, at which point the catch 22 moves again to the position of the new ammunition. The signal generator 21 and the external ammunition supply system 19 are controlled to be opened and closed through the closed controller 40, so that whether the external ammunition supply system is put into use or not is controlled according to requirements.

Every time the driving shaft 2 rotates for one circle, each V-shaped concave line 3 drives each active trigger 7 to reciprocate up and down once (namely, trigger once), and meanwhile, ammunition feeding and shell withdrawing are carried out once. If the number of the V-shaped concave lines is X and the number of the active percussion devices is Y, the driving shaft rotates once, the number of times of feeding and ejecting shells is Z, and Z is X × Y, and if the rotation speed of the driving shaft is a per minute, the number of times of feeding and ejecting shells is a minute, Z is a X × Y.

The multi-tube multifunctional short-range defense device provided by the invention not only can further improve the shooting speed, but also can simultaneously or selectively use ammunition with multiple functions, can effectively inhibit the overheating problem generated by a launching tube working for a long time, and can relatively improve the accuracy of the shot launched by a non-rotating-tube type gun body without centrifugal force compared with a rotating tube type gun body. Such as: the speed of the driving system is 1000 rpm, the driving shaft is provided with 6 groups of V-shaped concave lines and arc firing pin plectrums, and 6 groups of fixed launching tubes, 6 groups of signal generators, 6 groups of active percussion devices and 6 groups of bullet conveying and supplying systems are simultaneously used, so that the firing rate per minute is 1000 multiplied by 6 which is 36000 shots/min, the firing rate per unit time under the same speed is at least 3 times higher than that of a near-defense system H/PJ-11 type (1130 type) near-defense cannon, and if the speed of the driving system is increased to 1500 rpm, the firing rate per minute is 1500 multiplied by 6 which is 54000 shots/min. The principle of the device can also be used on light and heavy machine guns or rifles, the electric drive rotary firing system can automatically feed and withdraw shells for the guns without the help of the recoil force of ammunition gas, the firing speed is adjustable, and the shell clamping phenomenon of ammunition caused by misfiring can be reduced. The process that a single-shot gun needs manual ammunition feeding after shooting each time or a continuous-shot gun needs manual ammunition feeding when shooting for the first time is omitted, the structure is simpler and more compact, the whole weight of the gun is greatly reduced while the firepower is increased, and the stability is improved.
