DETAILED DESCRIPTION

[0028] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] The present invention provides a method for destroying small-caliber dangerous and explosive objects by laser arrangement, comprising the following steps:

[0030] (1) Preparation work, arrangement and layout: Lay out safety explosion-proof facilities, small-caliber dangerous explosives 00 and laser transmitters 1, and arrange several dangerous explosives 00 in a straight line and / or diagonal line in the safety explosion-proof facilities. Among them, the safety explosion-proof facilities include explosion-proof walls 2, which are semi-enclosed local protection spaces composed of a top plate, a rear side plate, and left and right side plates. The top plate, rear side plate, and left and right side plates are all explosion-proof unit structures filled with inert media such as sand, gravel or water.

[0031] In addition, the safety explosion-proof facility also includes an explosion-proof partition wall 19, which is arranged on the emission end side of the laser emitter 1, and is provided with an emission port 20 for passing laser; the explosion-proof partition wall 19 is an explosion-proof unit structure filled with an inert medium.

[0032] like Figure 1 , 2 As shown, the in-line arrangement means that a number of explosive and dangerous objects 00 are arranged vertically at intervals on a horizontal straight line, and the top plate, rear side plate and left and right side plates of the explosion-proof wall 2 are respectively arranged on the top, rear and left and right sides of a row of explosive and dangerous objects 00; the tail of the explosive and dangerous object 00 is inserted into the steel cylinder 3, the inner diameter of the steel cylinder is slightly smaller than the maximum diameter of the explosive and dangerous object, and the height is slightly larger than the tail length of the explosive and dangerous object; the lower ends of a number of steel cylinders 3 are welded and fixed on the base 4 at intervals. In order to facilitate transportation, handles 5 are also welded on the edges of both ends of the base 4.

[0033] like Figure 3 As shown, the oblique arrangement means that a number of explosive and dangerous objects 00 are arranged in two relatively parallel vertical plates 6, and a number of explosive and dangerous objects 00 are arranged at intervals along the inner walls of the two vertical plates 6 and between the two vertical plates 6. The explosive and dangerous objects 00 at the bottom are arranged vertically at intervals, and the explosive and dangerous objects 00 at the two sides are arranged at intervals and inclined upward; the top plate, rear side plate and left and right side plates of the explosion-proof wall 2 are respectively arranged at the top, rear and left and right sides of a row of explosive and dangerous objects 00; the tail of the explosive and dangerous objects 00 is inserted into the steel cylinder 3, and a number of steel cylinders 3 are respectively fixed vertically on the base 4 and obliquely fixed on the inner wall of the vertical plate 6. Among them, the vertical plate is made of steel; for the convenience of transportation, handles are welded at the ends of the base and the vertical plate; a number of steel cylinders 3 are linearly arranged on the vertical plate 6 and the base 4.

[0034] (2) Safety layout: Figure 1 As shown, the laser transmitter 1 is arranged at a certain safe defense distance from the dangerous explosive 00. The safe defense distance is determined according to the equivalent TNT equivalent of a single dangerous explosive, which is specifically calculated by normalizing the weight of the dangerous explosive, the shell material, the charge type and weight, the combustion and explosion characteristics and other parameters into the equivalent TNT equivalent; the maximum values ​​of the shock wave destruction distance and the fragment killing distance of the dangerous explosive are comprehensively selected as the base of the safe defense distance, and the corresponding safety margin is assigned as the destruction safety distance. When an explosion-proof partition wall is arranged on one side of the transmitting end of the laser transmitter, the destruction distance can be appropriately shortened, and the minimum destruction safety distance cannot be less than the maximum killing radius of the dangerous explosive to be destroyed.

[0035] (3) Dimming destruction: adjust the laser transmitter and aim at the dangerous and explosive materials. After adjusting the laser transmitter power, irradiation position, spot size, destruction distance and irradiation time and other laser destruction characteristic parameters to the explosion threshold of the dangerous and explosive materials to be destroyed, keep the parameters unchanged. Among them, the irradiation position usually gives priority to sensitive detonating elements. For dangerous and explosive materials that need to remove sensitive detonating elements, the center of the charge is usually selected to improve the thoroughness of the first destruction and avoid secondary hazards. The laser destruction equipment is powered by batteries and AC power. The advantage of using batteries is that it is easy to destroy by mobile means and suitable for sporadic destruction; the advantage of using AC power is that it can supply electricity continuously and stably, which is convenient for batch destruction operations.

[0036] (4) Destruction of dangerous and explosive materials:

[0037] For batches of dangerous and explosive materials arranged in a serial manner, after the current dangerous and explosive material explodes, the deflection angle of the laser emitter is adjusted to aim at the next dangerous and explosive material, and the laser emission is continued until all the arranged dangerous and explosive materials are destroyed, and then the laser emission is stopped.

[0038] For batches of dangerous and explosive materials arranged in an oblique pattern, after the current dangerous and explosive material explodes, the deflection angle and elevation angle are adjusted to aim at the next dangerous and explosive material without stopping until all the dangerous and explosive materials in one arrangement are destroyed, and then the laser emission is stopped.

[0039] (5) Post-processing:

[0040] After the first batch of dangerous and explosive materials are destroyed, use long-handled pliers to clean up the destroyed remains, and re-arrange the dangerous and explosive materials according to step (1) to continue the destruction.

[0041] In a specific embodiment of the present invention, Figure 1 , 4 As shown in Figures 6 and 7, the laser emitter 1 is arranged on the support frame 7. The chassis of the laser emitter 1 is connected to the support of the support frame 7 through a horizontal angle adjustment mechanism. The horizontal angle adjustment mechanism includes a horizontal angle adjustment button 8 and a horizontal ratchet 9. The horizontal angle adjustment button 8 and the horizontal ratchet 9 are coaxially fixed with the chassis. A first ratchet 10 for limiting the position of the horizontal ratchet 9 is also provided on one side. The swing angle of the laser emitter in the horizontal plane can be adjusted by turning the horizontal angle adjustment button. The horizontal angle adjustment button rotates while driving the horizontal ratchet to rotate. With the help of the first ratchet, the laser is aimed at the dangerous and explosive materials arranged in a straight line one by one in one direction for continuous destruction.

[0042] In another specific embodiment of the present invention, Figure 5 As shown, a pitch angle adjustment mechanism is also provided between the chassis of the laser transmitter 1 and the horizontal angle adjustment mechanism, and the pitch angle adjustment mechanism includes a support seat 11, a gear 12, a pitch angle adjustment button 13 and a vertical ratchet 14. An arc groove 15 is provided at the bottom of the chassis, and an inner tooth meshing with the gear 12 is provided in the arc groove 15. The gear 12 is arranged in the support seat 11, and the gear 12, the pitch angle adjustment button 13 and the vertical ratchet 14 are coaxially fixed. A second ratchet (not shown in the figure) is provided on the front side of the vertical ratchet 14. Similarly, the pitch angle of the laser transmitter in the vertical plane can be adjusted by rotating the pitch angle adjustment button, and the dangerous and explosive materials on the opposite plates can be destroyed one by one. With the help of the second ratchet, the laser can be used to complete the destruction of the dangerous and explosive materials on the same vertical plate along one direction, and then the horizontal angle adjustment button is adjusted to destroy the horizontally arranged dangerous and explosive materials one by one, and finally the dangerous and explosive materials on the other side of the vertical plate are destroyed.

[0043] When making specific Figure 5As shown, the vertical ratchet 14 and the horizontal ratchet 9 are respectively arranged in the upper shell 17 and the lower shell 16, and the edge of the lower shell 16 is provided with a pawl limiting shell 18 that passes through its inner cavity, the middle part of the first pawl 10 is rotatably connected to the pawl limiting shell 18, and the braking end of the first pawl 10 can cooperate with the ratchet teeth of the horizontal ratchet 9, and the end of the first pawl 10 extends from the outlet of the pawl limiting shell 18 to the outside, and is connected to its inner wall through a spring 19, and the horizontal ratchet 9 is released and braked by moving the first pawl 10 back and forth; the edge of the upper shell 15 is provided with a pawl limiting shell that passes through its inner cavity, and the middle part of the second pawl is rotatably connected to the pawl limiting shell, and the braking end of the second pawl can cooperate with the ratchet teeth of the vertical ratchet, and the end of the second pawl extends from the outlet of the pawl limiting shell to the outside, and is connected to its inner wall through a spring, and the vertical ratchet 14 is released and braked by moving the second pawl up and down.

[0044] To further optimize the above technical solution, the support frame 7 adopts a foldable structure, which is convenient for storage and carrying after the operation is completed.

[0045] In summary, the present invention has a simple structure, low manufacturing cost, and convenient operation. It has the advantages of safety, efficiency, and reliability. The present invention is particularly suitable for the batch destruction of small-caliber dangerous and explosive materials of the same model. By changing the spatial arrangement and layout of multiple target dangerous and explosive materials, the laser continuous irradiation is guided to achieve the purpose of one-time dimming and continuous destruction of multiple target dangerous and explosive materials, solving the problem of low efficiency in the destruction of batch dangerous and explosive materials and small-caliber dangerous and explosive materials. Compared with the non-arrangement destruction method, the present invention can achieve the effect of "one-time dimming and continuous destruction", reduce the frequency of service operations such as dangerous and explosive material placement and setting, safety distance defense, laser aiming and emission adjustment, and opening and closing, shorten the service operation time, and improve the operation efficiency.

[0046] In the above description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed above.
