Description
Technical Field
The invention relates to the technical field of penetration preventing structures. And more particularly to an intelligent barrier apparatus against ammunition strike.
Background
The purpose of accurate striking is to hit the target, and the second is that ammunition is penetrated to the appointed position for explosion, and the striking mode forms a great threat to the survival safety of some important targets. The materials used for the current protective structure are mainly common materials and high-end armor materials. High-end armor materials are expensive, while common materials are thick and heavy in construction. When the novel weapon is used for penetration, the material performance of the protective structure in the traditional protective engineering is limited, the economic benefit is poor, and the construction process is complex. Many surface layer protection structures in the prior art need to be integrally paved to achieve the penetration resistance effect. Considering the factors of the maximum bearing of the top of the protected structure, the construction difficulty, the economy and the like, the mode of integral arrangement above the protection area cannot be adopted by most buildings. For this reason, it is desirable to propose an intelligent rigid barrier device that can be constructed using common materials to reduce the weight of the structure, reduce the power requirements on the motor in the follower mechanism, and achieve precise protection of important objectives.
Disclosure of Invention
Aiming at the problems existing in the prior art, the invention aims to provide an ammunition-striking-resistant intelligent obstacle device, which can control the motion vector of a missile to deviate from a target and fall into an ideal position, for example, the target is prevented from being destroyed by inducing the striking missile to an open area around a building, and meanwhile, the additional damage is reduced to the greatest extent. The bulletproof can be precisely hit by the timely motorized breaking according to the threat. The obstacle realizes the precise protection of important targets by controlling the motion vector of the missile. Meanwhile, the invention is suitable for the conditions that no equipment or pipelines exist at the newly built and built tops and other facilities exist at the tops. The rigid obstacle comprises two hollow triangular prisms with the same structure, wherein the top sharp angle is alpha, the inclined side length is a, the bottom side length is b/2, the cross section of each hollow triangular prism is a right triangle, and under the condition that a detection system does not detect an attack projectile body in an initial state, the two hollow triangular prisms are back to back, the cross section of the spliced hollow structure is isosceles triangle, 2 alpha is less than 90 degrees and b is less thanTypically a < 3. If no equipment or pipeline exists at the top of the object to be protected, the rigid barrier can keep continuous in the length direction of the rigid barrier, and according to the theoretical landing point of an incoming projectile body, the two hollow triangular prisms are driven to perform controlled movement from an initial position, such as the center of the top of a building by virtue of respective follow-up mechanisms. If other facilities exist, the rigid barrier can be divided into multiple sections along the length direction of the rigid barrier, and each section of the rigid barrier has the same structure as the non-segmented rigid barrier. The two hollow triangular prisms of each section of rigid barrier are driven by the respective follow-up mechanism to perform controlled movement. The rigid barrier is used for controlling the falling point of an incoming projectile body, so that the directional bullet is realized. The bottom of the follow-up mechanism is fixedly connected with the installation fixing base, the installation fixing base is arranged at the top of an important target to be protected, for example, the top of a building, so that the accurate protection of the important target is realized, and meanwhile, the motion vector of the missile can be controlled and the collateral damage is reduced through the invention. Preferably, if the span of the hypotenuse of the hollow triangular prism is too large, a support plate needs to be arranged inside the hollow triangular prism to form a linear support. The support plate prevents the occurrence of adverse deflection while ensuring the strength and rigidity of the rigid barrier.
The technical scheme of the invention is as follows:

The length direction of the protected surface is the movement direction of the rigid barrier. In parallel, the length of the guide rail is smaller than that of the surface to be protected, edge regions are arranged at two ends of the surface to be protected in the length direction, and the sum of the lengths of the two edge regions and the length of the guide rail is equal to that of the surface to be protected. After hitting the edge area, the projectile exits the protected structure after striking the edge area due to the weaker outside constraint.
Preferably, the length of the guide rail is smaller than the length of the surface of the protected structure, edge areas are arranged at two ends of the surface of the protected structure in the length direction, fixed vector protection areas are respectively arranged at the inner sides of the edge areas, and the length direction of the fixed vector protection areas is the movement direction of the rigid barrier. The inner sides of the two edge areas are respectively provided with a respective fixed vector protection area, and the placement direction of the hollow triangular prism is determined in the fixed vector protection area according to the controlled area where the fixed vector protection area is positioned, for example, the first controlled area or the second controlled area, and the inclined plane of the hollow triangular prism is always outwards.
The sum of the length L2 of the two fixed vector guard areas, the length L1 of the two edge areas and the length of the rail is equal to the length of the surface to be protected. After the projectile hits the edge region, the projectile flies directly out of the protected structure due to the weaker outside constraint. By means of the arrangement of the fixed vector protection area, the length of the guide rail can be effectively reduced, and therefore the impact range of the rigid barrier is reduced. Let d be the range of motion of the individual rigid barrier and a be the size of the bottom of the individual rigid barrier. In the initial state, a single rigid barrier is arranged at the center of a movement range d, and the movement path of the single rigid barrier is d/2-a/2; 2l1+2l2+d is equal to the required laying length L;
the length direction of the edge area is the movement direction of the rigid barrier. The length of the edge area is 10-15 times the spring diameter. Further, for a penetration body of 30cm in diameter, the edge region has a length of 1-1.5m.
And under the condition that the rigid barrier is not segmented, the motors of the first follower mechanisms synchronously move. The motors of the second follower mechanisms synchronously move.
The rigid barrier according to the invention is in fact a directed springing module, each hollow triangular prism comprising a top, a bottom and two sides, which cross upwards forming a top, which is a line, also known as a pointed top. The inclined side part of the two side parts is a collision surface, and the direction of the projectile body is changed through the collision surface in the collision process, so that the control of the bullet jump is realized.
Preferably, the hollow triangular prism can reduce the quality of the rigid barrier and reduce the requirement on the power of the motor of the follow-up mechanism as long as the strength of the hollow triangular prism can meet the protection requirement. The hollow triangular prism can be of a steel structure or a reinforced concrete structure, and if the hollow triangular prism is of the reinforced concrete structure, the outside of the hollow triangular prism can be protected by a steel plate so as to increase the strength of the structure.
If a rigid barrier is provided and is sized to cover the location where protection is desired, the rigid barrier may be secured to the roof or by other structures that enable it without controlled movement by a follower mechanism.
If other facilities exist at the top of the protected object, the rigid barrier can be divided into multiple sections along the length direction of the rigid barrier, and each section of rigid barrier has the same structure as the non-segmented rigid barrier. The two hollow triangular prisms of each section of rigid barrier are driven by the respective follow-up mechanism to perform controlled movement. The rigid barrier is used for controlling the falling point of an incoming projectile body, so that the directional bullet is realized. The rigid barriers determine the lengths of the segmented rigid barriers according to the conditions of other facilities at the top of the protected object. Each section of rigid barrier is supported by at least one first follower and at least one second follower, respectively. The concrete implementation mode is the same as that of the integral rigid barrier. Preferably, the segments of the segmented rigid barrier are individually controllable in motion.
The above description is only of the preferred embodiments of the present invention and is not intended to limit the present invention, but various modifications and variations can be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
