Description

Technical Field

[0001] The utility model belongs to the technical field of explosive destruction, and in particular relates to a multi-jet energy-gathering device for destroying underwater unexploded bombs. Background Art

[0002] Unexploded bombs pose a safety hazard and need to be destroyed in a timely manner to protect people's lives and property. At present, the destruction of unexploded bombs on the ground has mature technology, and the destruction methods range from ammunition incineration, explosive detonation, chemical decomposition to cutting destruction, laser destruction, and shaped jet destruction. However, the destruction of unexploded bombs underwater is rarely reported. Due to the presence of water pressure, vision and interference, the placement of shaped bombs, connection of detonators, and operation of equipment that can be easily completed on land are difficult to complete accurately underwater. Underwater destruction is more difficult than land destruction. Therefore, the bomb disposal operation method on land cannot be fully applied underwater. Compared with land destruction, underwater destruction has special requirements in construction technology, selection of explosives, calculation of dosage, detonation network, and safe distance.

[0003] If underwater unexploded bombs are buried by a large amount of silt, it is difficult to detect and salvage them. In addition, the underwater environment is complex. Under normal circumstances, underwater unexploded bombs are destroyed on the spot. However, there is currently no effective, safe and reliable means of disposing of underwater unexploded bombs. Therefore, unexploded bombs are generally salvaged and destroyed on land. However, the salvage process has certain safety hazards. For this reason, we propose a multi-jet focused energy device for destroying underwater unexploded bombs. Utility Model Content

[0004] The utility model aims to provide a multi-jet energy-focusing device for destroying underwater unexploded bombs, aiming to solve the problems raised in the above-mentioned background technology.

[0005] The embodiment of the utility model is implemented as follows: a multi-jet energy-focusing device for destroying underwater unexploded bombs, comprising:

[0006] Detonating cord, connected to the detonator;

[0007] A multi-point time-delay detonation transmission network, wherein the input end of the multi-point time-delay detonation transmission network is connected to the detonating cord;

[0008] The explosive transmission output assembly is connected to the shaped charge jet bomb;

[0009] A fixing bracket, the fixing bracket being connected to the shaped charge jet bullet and being used to fix the position of the shaped charge jet bullet;

[0010] A shaped charge jet projectile is fixed on a fixed bracket;

[0020] Furthermore, the explosion transmission output component includes:

[0021] Sealant is poured between the connection cap and the output end of the multi-point time-delay explosion transmission network and between the sealing cap and the output end of the multi-point time-delay explosion transmission network;

[0022] A connecting cap is arranged between the output end of the multi-point time-delay detonation transmission network and the upper cover of the shaped-energy jet bomb;

[0027] Furthermore, the detonating cord is detonated by a security agency.

[0028] Furthermore, the number of output terminals of the multi-point delayed detonation network matches the number of shaped-charge jet bombs; when the number of shaped-charge jet bombs is only one, the multi-point delayed detonation network may not be used.

[0029] Compared with the prior art, the beneficial effects of the utility model are:

[0030] 1. The multi-jet shaped charge device for destroying underwater unexploded bombs improves the effectiveness and reliability of underwater unexploded bomb destruction.

[0040] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0041] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0042] Embodiment 1, as Figure 1 As shown, a multi-jet energy-focusing device for destroying underwater unexploded bombs provided by an embodiment of the utility model comprises:

[0043] Detonating cord 1, connected to the detonator;

[0044] A multi-point time-delay detonation transmission network 2, the input end of which is connected to the detonating cord 1;

[0045] The explosion transmission output assembly 3 is arranged on a fixed bracket 4;

[0046] A fixed bracket 4, wherein the fixed bracket 4 is connected to the shaped-energy jet bullet 5 and is used to fix the position of the shaped-energy jet bullet 5;

[0047] The shaped-charge jet bomb 5 is connected to the multi-point delayed detonation network output terminal 31 in the detonation output component 3 .

[0048] An embodiment of the present invention provides a method for destroying underwater unexploded bombs with a multi-jet energy focusing device, comprising the following steps:

[0049] S1: Connect the shaped-energy jet projectile 5 and the fixing bracket 4 and adjust them;

[0050] S2: According to the design of the destruction operation, place the fixed bracket 4 at the possible charging position of the unexploded bomb, and adjust the height and angle;

[0051] S3: Connect the fixed bracket 4 and the multi-point delayed detonation network output terminal 31. The number of output terminals can be left free to install other equipment;

[0052] S4: Ensure that the multi-point delayed detonation network output terminal 31 is reliably connected to the shaped energy jet bomb 5 through the detonation output component 3;

[0053] S5: an input terminal connected to the detonating cord 1 and the multi-point time-delay detonation transmission network 2;

[0054] S6: After confirming that personnel, equipment and environment are safe, connect the detonator and detonating cord 11;

[0055] S7: Perform the operation.

[0056] Embodiment 2, as Figure 4As shown, a multi-jet focused energy device for destroying underwater unexploded bombs is provided in one embodiment of the utility model. The difference between this embodiment and embodiment 1 is that the detonating cord 1 is replaced by a security mechanism 6. After receiving the detonation signal from the water surface, the security mechanism 6 performs detonation, which reduces the operation steps of connecting the detonator and increases safety.

[0057] In the first and second embodiments, the number of shaped-energy jet bombs 5 matches the number of multi-point delayed detonation network output terminals 31, and they are at least one-to-one connected. They are all controlled by an input terminal of the multi-point delayed detonation network 2, and can meet the requirements of single-emission stream destruction, double-emission stream destruction, or multi-point jet destruction; when the same delay time is set, synchronous destruction can be achieved; when different delay times are set, sequential destruction can be achieved.

[0058] Embodiment 3, as Figure 5 As shown, a multi-jet shaped-energy device for destroying underwater unexploded bombs is provided by an embodiment of the utility model. The difference between this embodiment and embodiment 1 is that the multi-point delayed detonation network 2 is removed. It is suitable for the situation where the underwater working environment is good and the charging position of the unexploded bomb is easy to determine. In this case, only a single shaped-energy jet bomb 5 is needed to complete the destruction operation at one time.

[0059] Embodiment 4, as Figure 6 As shown, a multi-jet focused energy device for destroying underwater unexploded bombs is provided by an embodiment of the utility model. The difference between this embodiment and embodiment 3 is that the detonating cord 1 is replaced by a security mechanism 6, which is suitable for the situation where the underwater working environment is good and the charging position of the unexploded bomb is easy to determine, and the operation safety is good. After the security mechanism 12 receives the detonation signal from the water surface, the security mechanism 12 is used to detonate, which reduces the operation steps of connecting the detonator and increases the safety.

[0060] In the above-mentioned embodiments 1-4, the output end of the shaped charge bomb may also be provided with a soft metal sealing film.

[0061] like Figure 1-Figure 6 As shown, as a preferred embodiment of the utility model, the shaped energy jet bomb 5 includes:

[0062] The shaped-charge jet bomb upper cover 51 is connected to the fixed bracket 4 through the explosion transmission output assembly 3;

[0063] The booster charge column 52 is located in the energy-gathering shell 54;

[0064] The second sealing ring 53 is arranged between the energy-gathering shell 54 and the upper cover 51 of the shaped-energy jet bullet;

[0065] The shaped-energy shell 54 is fixedly connected to the shaped-energy jet bullet upper cover 51;

[0066] A main charge 55, which is loaded in the energy-gathering shell 54 and contacts the booster charge column 52;

[0067] The liner 56 is arranged below the main charge 55;

[0068] A sealing ring 3 57 is provided between the energy collecting shell 55 and the sealing end cover 58;

[0069] The sealing end cover 58 is disposed at the bottom of the energy gathering shell 54 .

[0070] like Figure 2 and Figure 3 As shown, as a preferred embodiment of the utility model, the shaped charge bomb upper cover 51, the explosive column 52, the shaped charge shell 54, the main charge 55, the charge liner 56 and the sealing end cover 58 are all axisymmetric structures.

[0071] like Figure 1-Figure 6 As shown, as a preferred embodiment of the present utility model, the explosion transmission output component 3 includes:

[0072] Sealant 32, used to ensure sealing;

[0073] In Example 1 and Example 2, the sealant 32 is poured between the connection cap 33 and the output end 31 of the multi-point time-delay transmission network and between the sealing cap 35 and the output end 31 of the multi-point time-delay transmission network;

[0074] In Example 3, the sealant 32 is poured between the connecting cap 33 and the detonating cord 1 and between the sealing cap 35 and the detonating cord 1;

[0075] In Embodiment 4, the sealant 32 is poured between the connection cap 33 and the output end of the security mechanism 6 and between the sealing cap 35 and the output end of the security mechanism 6 .

[0076] In Embodiment 1 and Embodiment 2, the connection cap 33 is disposed between the multi-point delayed detonation transmission network output end 31 and the shaped-energy jet bomb upper cover 51;

[0077] In embodiment 3, the connecting cap 33 is disposed between the detonating cord 1 and the upper cover 51 of the shaped-charge jet bomb;

[0078] In Embodiment 4, the connection cap 33 is disposed between the output end of the security mechanism 6 and the upper cover 51 of the shaped energy jet bomb.

[0079] The compression nut 34 is threadedly connected to the shaped-energy-jet bullet upper cover 51 to ensure a reliable connection.

[0080] In Embodiment 1 and Embodiment 2, the sealing cap 35 is disposed between the output end 31 of the multi-point time-delay transmission network and the upper cover 51 of the shaped-energy jet bomb;

[0081] In embodiment 3, the sealing cap 35 is disposed between the detonating cord 1 and the upper cover 51 of the shaped-charge jet bomb;

[0082] In Embodiment 4, the sealing cap 35 is disposed between the output end of the security mechanism 6 and the upper cover 51 of the shaped energy jet bomb.

[0083] A sealing ring 36 is disposed between the connecting cap 33, the sealing cap 35 and the upper cover 51 of the shaped energy jet projectile.

[0084] The detonation process of Example 1 is as follows: after the detonator is detonated, the detonating cord 1 detonates the multi-point delayed detonation transmission network 2, and the output end 31 of the multi-point delayed detonation transmission network synchronously or delayedly detonates the detonating charge column 52 in the multiple or single shaped charge jet bomb 5 according to the design requirements, thereby detonating the main charge 55. After the main charge 55 is detonated, a detonation wave is generated, which pushes the charge liner 56 to form a high-speed, high-density metal jet along the axis direction of the charge liner 56 with a speed of about 8000m / s, which can easily penetrate the shell of the unexploded bomb and detonate the explosives in the unexploded bomb, thereby achieving the purpose of destroying the unexploded bomb.

[0085] The difference between the detonation process of Example 2 and the detonation process of Example 1 is that the security mechanism 6 detonates the multi-point delayed detonation network 2 after receiving the detonation signal from the water surface.

[0086] The detonation process of Example 3 is as follows: after the detonator is detonated, the detonating cord 1 detonates the booster charge 52, thereby detonating the main charge 55. After the main charge 55 is detonated, a detonation wave is generated, which pushes the charge liner 56 to form a high-speed, high-density metal jet along the axis of the charge liner 56 with a speed of about 8000m / s, which can easily penetrate the shell of the unexploded bomb and detonate the explosive in the unexploded bomb, thereby achieving the purpose of destroying the unexploded bomb.

[0087] The difference between the detonation process of Example 4 and the detonation process of Example 3 is that the security mechanism 6 detonates the booster column 52 in the shaped charge bomb after receiving the detonation signal from the water surface.

[0088] The above are only preferred implementations of the utility model. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the utility model. These should also be regarded as the protection scope of the utility model. These will not affect the effect of the implementation of the utility model and the practicality of the patent.
