Even, there are still many unexploded ammunitions left in some waters during the war.

[0003] These underwater unexploded ammunitions may include various types of shells, bombs, and missiles, etc. They may explode when disturbed, such as being touched by waves, ships, fishing nets, or underwater animals. Such an explosion will not only cause casualties and property losses but also damage the marine environment. Since underwater unexploded ammunitions are buried in soil or water for a long time, their fusing mechanisms may fail due to corrosion, but the harmful substances in the projectile body will still pollute the surrounding environment. Therefore, it is of great significance to study a safe and reliable destruction device and a destruction method for underwater explosives. Summary of the Invention

[0019] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and cannot be used to limit the protection scope of the present invention.

[0020] Embodiment 1

[0021] This embodiment provides a destruction device for underwater exposed explosives, as Figure 1 shown, including a shaped charge cutting component 1, a timed detonating fuse component 2, and a binding component 3. Among them, the shaped charge cutting component 1 forms a metal jet through the shaped charge effect of the main charge 14 inside and the metal liner 12, and is used to form a radial linear slit on the surface of the explosive. Specifically, referring to Figure 2 and Figure 3 , the shaped charge cutting component 1 includes a shaped charge housing 11 and a metal liner 12. The metal liner 12 is arranged inside the shaped charge housing 11 and divides its internal space into a first space and a second space; among them, the first space is used to fill the main charge 14, and the shaped charge housing 11 forms a cutting action surface 110 on the side close to the second space, which is convenient for closely adhering to the surface of the explosive.

[0022] Furthermore, the timed detonating fuse component 2 is connected to the shaped charge housing 11 on the upper side of the shaped charge cutting component 1, and is used to ignite the main charge 14 in the shaped charge cutting component 1 according to a predetermined duration after the start switch is activated. Combining Figure 3 andFigure 4 The time-delay detonating fuse component 2 includes a fuse housing 20, a safety mechanism and a detonator tube 23 inserted into the fuse housing 20, and a time-delay circuit 24 arranged in the inner space of the fuse housing 20. Among them, the safety mechanism is used to control the on-off of the time-delay circuit 24, the time-delay circuit 24 is used to delay the triggering of the detonator tube 23 when it is turned on, and the detonator tube 23 is used to ignite the main charge 14 when it is triggered.

[0023] In this embodiment, referring to Figures 1 to 3 The binding component 3 is connected to the shaped charge housing 11 on the lower side of the shaped charge cutting component 1, and is used to slightly fix the shaped charge cutting component 1 at the middle position of the explosive along the radial direction of the underwater exposed explosive, and make the cutting surface 110 closely adhere to the surface of the explosive.

[0024] The destruction device for underwater exposed explosives provided in this embodiment forms a metal jet through the shaped charge effect of the main charge and the metal liner, forms a radial linear slit on the surface of the underwater exposed explosive, and adopts a fuse component that can achieve underwater timed detonation without the operator pulling the wire, improving the safety and reliability of the destruction.

[0025] As an embodiment, in combination with Figures 1 to 3 The metal liner 12 can be arranged to extend along the radial direction of the underwater exposed explosive. Therefore, the plane where the cross-section of the metal liner 12 is located is parallel to the axis direction of the explosive, and the plane where the extension direction is located is perpendicular to the axis direction of the explosive. Referring to Figure 3 The cross-section of the metal liner 12 can be set to a V shape or an arc shape. The cone angle of the V-shaped liner can be set to 80° or 120°. Therefore, the metal liner 12 will form a convex side and a concave side. In this embodiment, the space separated by the convex side is set as the first space, and the space separated by the concave side is set as the second space. Through the separation effect of the metal liner 12, the main charge 14 and the metal liner 12 can cooperate to form a metal jet through the shaped charge effect, and the formed metal jet will shoot out from the cutting surface 110 to burn through the outer shell of the explosive.

[0026] It should be noted that in order to enable the metal jet to reliably penetrate the thick explosive shell and detonate the explosive after shooting out from the cutting surface 110, the shaped charge housing 11 of the shaped charge cutting component 1 can be made of aluminum alloy with a thickness of 3 mm, and the connection part can be fixed with screws and sealed with epoxy glue. The main charge 14 can be made with a pressing density of 1.7 g / cm 3And PBX-2 explosive with a standoff distance of 32 mm. Since the main charge 14 in the shaped charge cutting component 1 has a sealed air standoff distance, it avoids the problem that the metal jet formed by the shaped charge effect prematurely contacts the water medium, resulting in a rapid decrease in the jet velocity and temperature and unable to reliably penetrate the explosive housing with a large thickness and detonate the explosive. In addition, the explosive in this embodiment refers to a cylindrical explosive, so the cutting action surface 110 proposed in this embodiment can be configured as an arc surface to better fit the arc surface of the cylindrical explosive. In actual engineering applications, the material of the shaped charge housing 11, the composition of the main charge 14, and the shape of the cutting action surface 110 can all be set according to the actual operating conditions to meet different task requirements.

[0027] The destruction device for underwater exposed explosives proposed in this embodiment, by the arc surface of the cutting action surface 110 closely adhering to the surface of the underwater exposed explosive, uses the main charge 14 after ignition and the metal liner 12 to generate a metal jet, forming a radial linear cut on the surface of the explosive housing, facilitating the exposed explosive to be formed into two halves, and can achieve reliable induced detonation and destruction of explosives with a housing thickness of 3 cm. Among them, the linear cut forms a pressure relief channel for the internal explosive, causing a stress concentration area in the explosive, thus easily causing the exposed explosive to detonate and enabling it to release energy as soon as possible. In addition, the plane where the linear cut is located is perpendicular to the axis direction of the explosive. When detonating, the explosive is cut into two large fragments in the front and back directions along the cut, which can avoid generating many small fragments. Compared with a large number of small fragments, the fragments formed by the linear cut are fewer and have less lethality, and the large fragments have a greater resistance in water, improving the safety distance of detonation.

[0028] Furthermore, as Figure 3 shown, the shaped charge housing 11 includes a first housing 111 and a second housing 112. The first housing 111 and the second housing 112 are designed as a symmetrically separable structure. The metal liner 12 can be made of a copper plate with a thickness of 1.2 mm, which is convenient for installing the metal liner 12 into the shaped charge housing 11. In addition, baffles 13 are respectively provided on the inner walls of the first housing 111 and the second housing 112. The baffles 13 are detachably connected to the inner walls of the shaped charge housing 11, and can play a role in supporting and sealing the two ends of the metal liner 12. When the first housing 111 and the second housing 112 are joined together, the metal liner 12 is pressed and arched, and is arranged at a predetermined position in the shaped charge housing 11 under the support of the baffles 13, so that the internal space of the shaped charge housing 11 is isolated to form independent first and second spaces, and the main charge 14 is hermetically stored in the first space.

[0029] As an alternative embodiment, refer to Figures 1 to 3Two pairs of connection structures 113 are respectively provided at the left and right ends of the first shell 111 and the second shell 112, wherein the connection structure 113 of the first shell 111 is connected to the connection structure 113 of the second shell 112 through a fixing structure 114. Specifically, the connection structure 113 may be a lug with a screw hole, and the fixing structure 114 may be a bolt connected to the screw hole. When assembling the first shell 111 and the second shell 112, four bolts are connected to the four pairs of screw holes respectively, so that the first shell 111 and the second shell 112 can be matched, and the gaps can be filled with sealant.

[0030] In this embodiment, if Figure 4 As shown, the fuse housing 20 is formed by a sealed assembly of a third housing 202 and a fourth housing 201, and the fourth housing 201 can be provided with a screw hole to connect with the energy-gathering housing 11. Among them, the insurance mechanism includes an electronic switch 21 plugged into the third housing 202 and a mechanical insurance 22 plugged into the fourth housing 201, and the electronic switch 21 and the mechanical insurance 22 are used to control the on-off state of the delay circuit 24. The fourth housing 201 is plugged with a battery 25 and a detonating tube 23, and the detonating tube 23 is provided with a flame detonator 231; the battery 25 can be a lithium battery, and the flame detonator 231 is supplied with power through the delay circuit 24, and the flame detonator 231 is used to ignite the detonating tube 23 when powered on. In addition, the third housing 202 is plugged with an indicator light 26 connected to the delay circuit 24, which is used to indicate the on-off state of the delay circuit 24.

[0031] Furthermore, the mechanical safety 22 includes a magnetic switch, which switches between a first position and a second position by rotating to control the position state of the conductive sheet; wherein, when the magnetic switch is switched to the first position, the conductive sheet is in an attracted position, and the delay circuit 24 cannot be turned on by the electronic switch 21; when the magnetic switch is switched to the second position, the conductive sheet is in a released position, and the delay circuit 24 can be turned on by the electronic switch 21.

[0032] Specifically, the timed detonation fuse component 2 is powered by a built-in battery 25, and plays a double insurance role through the electronic switch 21 and the mechanical safety 22. When not in use, the magnetic switch is in the first position, that is, the isolated safety state; when the timed detonation fuse component 2 is combined with the energy-gathering cutting component 1, and the fuse needs to be started, the magnetic switch of the mechanical safety 22 is switched to the second position by rotation to release the first safety mechanism. Then turn on the electronic switch 21, and it can be observed through the indicator light 26 that the delay circuit 24 is turned on and powered on, and after the delay circuit 24 delays for a predetermined period of time, the detonation circuit starts to charge, and at this time, the flame detonator 231 is energized to ignite the detonating tube 23, and finally ignite the main charge 14 in the energy-gathering shell 11.

[0033] It should be noted that when the timed detonation fuse component 2 is in use, its preset duration can be adjusted in multiple gears, namely 30 minutes, 1 hour, and 2 hours, to be applicable to explosives of different sizes, so as to ensure that the operators can evacuate to a safe area. In actual engineering applications, the delay duration set by the timed detonation fuse component 2 can be set according to the actual operation conditions to meet different task requirements.

[0034] The destruction device for underwater exposed explosives provided in this embodiment detonates the shaped charge cutting component 1 by using the timed detonation fuse component 2 with a delay circuit 24. The timed detonation fuse component 2 can be waterproof and reliable in waters within 5 meters, eliminating the need for operators to pull the wire for detonation, enabling underwater timed detonation, avoiding the problem of operators dodging wires when surfacing, and providing more surfacing time and space for the operators. Moreover, the timed detonation fuse component 2 has two safety mechanisms, strong anti-electromagnetic interference ability, and is safer and more reliable to use, thus improving the safety and reliability of destruction.

[0035] In some embodiments, the binding component 3 is connected to the fixing structure 114 on the shaped charge housing 11. The binding component 3 can slightly fix the shaped charge cutting component 1 and the explosive by using cable ties, or can also use a clamp structure or other fixing parts for fixation, as long as it can achieve the fixing effect while reducing the explosion risk and not causing the explosive to roll, move, or collide. In addition, since this device is applicable to underwater work, all components need to be made of waterproof materials.

[0036] Embodiment 2

[0037] This embodiment provides a method for destroying underwater exposed explosives, using the destruction device described in Embodiment 1, which mainly includes the following steps: Step S1: After the operator carries the destruction device and dives to the position where the underwater exposed explosive is located and finds the target explosive, use the binding component 3 to fix the shaped charge cutting component 1 at the middle position of the explosive along the radial direction of the explosive, and make the cutting surface 110 closely adhere to the surface of the explosive. Step S2: Open the safety mechanism of the timed detonation fuse component 2 to conduct the delay circuit 24. Step S3: The operator surfaces within the preset duration and waits for the detonator 23 in the timed detonation fuse component 2 to trigger, so as to ignite the main charge 14 in the shaped charge cutting component 1, and then form a metal jet in combination with the metal liner 12 to destroy the underwater exposed explosive.

[0038] The destruction device and method for underwater exposed explosives provided by the embodiments of the present invention are different from the traditional conventional destruction methods: detonators are used for initiation and initiation circuits need to be set up. Not only do the detonators need to be waterproofed, but the initiation circuits need to be set up over a long distance to ensure safety, resulting in cumbersome underwater operations, slow speed, and low efficiency. Even worse, the initiation circuits may misfire after being exposed to water. When the operator reinspects the circuits, they may be in a dangerous situation. The present invention can form a metal jet through the shaped charge effect of the main charge and the metal liner, form a radial linear slit on the surface of the underwater exposed explosive, and use a fuse component that can achieve underwater timed initiation without the operator pulling a wire, improving the safety and reliability of destruction.
