If the theoretical drop point of the projectile body is in the second area, the motion controller controls the motor of the second follow-up mechanism to rotate forward to achieve the effect that the second hollow triangular prism moves towards the controlled motion area. To realize the controlled movement, the following design can be also carried out: if the theoretical drop point of the projectile body is in the first area, the motion controller controls a motor in the first follow-up mechanism to rotate reversely, so that the first follow-up mechanism drives the first hollow triangular prism to move towards the controlled motion area.

The length direction of the surface to be protected is the movement direction of the rigid barrier. In parallel, the length of the guide rail is smaller than that of the protected surface, edge areas are arranged at two ends of the surface of the protected structure in the length direction, and the sum of the lengths of the two edge areas and the length of the guide rail is equal to that of the protected surface. After the projectile hits the edge area, the projectile leaves the protected structure after impacting the edge area due to the fact that the outer constraint is weak.
Preferably, the length of the guide rail is less than the length of the surface of the protected structure, edge regions are arranged at two ends of the surface of the protected structure in the length direction, fixed vector protection regions are respectively arranged at the inner sides of the edge regions, and the length direction of each fixed vector protection region is the movement direction of the rigid barrier. The inner sides of the two edge regions are respectively provided with a respective fixed vector protection region, the arrangement direction of the hollow triangular prism is determined according to the controlled region where the fixed vector protection region is located, for example, the first controlled region or the second controlled region, and the inclined plane of the hollow triangular prism always faces outwards.
The sum of the length L2 of the two fixed vector protection zones, the length L1 of the two edge zones and the length of the guide rail is equal to the length of the surface to be protected. After the projectile body hits the marginal area, the projectile body directly flies out of the protected structure due to the fact that the outer side constraint is weak. Through the arrangement of the fixed vector protection area, the length of the guide rail can be effectively reduced, and therefore the hitting range of the rigid barrier is reduced. Let the range of motion of a single rigid barrier be d and the dimension of the base of each rigid barrier be a. In the initial state, a single rigid barrier is arranged at the center of a motion range d, and the motion path of the single rigid barrier is d/2-a/2; 2L1+2L2+ d equals the required length L of pavement;
the length direction of the edge area is the moving direction of the rigid barrier. The length of the edge area is 10-15 times of the diameter of the bullet. Furthermore, for a penetration body with a diameter of 30cm, the length of the edge region is 1-1.5 m.
And under the condition that the rigid barrier is not segmented, the motors of the first follow-up mechanisms synchronously move. And the motors of the second follow-up mechanisms move synchronously.
The rigid barrier according to the invention is in fact a directional ricochet module, each hollow triangular prism comprising a top, a bottom and two sides, the two sides crossing upwards to form a top, the top being a line, or tip. The inclined side part of the two side parts is a collision surface, and the direction of the bullet body is changed through the collision surface in the collision process, so that the bullet jump control is realized.
Preferably, the hollow triangular prism can reduce the mass of the rigid barrier by the hollow structure as long as the strength of the hollow triangular prism can meet the protection requirement, and the requirement on the power of the motor of the follow-up mechanism is reduced. 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 steel plate can be protected outside the hollow triangular prism so as to increase the strength of the structure.
If a rigid barrier is provided and sized to cover the location to be protected, the rigid barrier can be secured to the roof or by other available structures without controlled movement through a follower mechanism.
If other facilities exist on the top of the protected target, the rigid barrier can be divided into a plurality of sections along the length direction of the rigid barrier, and each section of the rigid barrier has the same structure as the unsegmented rigid barrier. Two hollow triangular prisms of each section of rigid barrier are driven by respective follow-up mechanisms to move in a controlled manner. The falling point of an incoming projectile body is controlled through the rigid barrier, and directional ricochet is realized. The rigid barrier determines the length of each rigid barrier after segmentation according to the condition of other facilities on the top of the protected target. Each section of rigid barrier is supported by at least one first following mechanism and at least one second following mechanism respectively. The specific implementation is the same as for a monolithic rigid barrier. Preferably, each segment of the segmented rigid barrier is separately controllably movable.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
