Description

Technical Field

[0001] The invention belongs to the technical field of cargo release, and in particular relates to an underwater destruction device. Background Art

[0002] In some fields, the destruction of dangerous goods, sensitive or confidential items is often involved, such as unexploded bombs left on battlefields during wars. Some of these unexploded bombs have become ineffective, but the risk of explosion of some unexploded bombs cannot be ruled out. Therefore, these unexploded bombs need to be destroyed. If conventional ground detonation is used, a larger safety area needs to be provided, and the destruction operators are exposed to greater safety risks. Therefore, there is an urgent need for devices that can destroy such items more safely and reliably. In the prior art, for example, the patent with application number "CN202110034775.0" and name "A safe destruction device for underwater explosives and its destruction method" is mainly used for the detonation and destruction of underwater unexploded bombs. The applicant found in the study that this solution is not suitable for the use of some items to be destroyed on land, and its flexibility and reliability are relatively poor. Summary of the invention

[0003] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present invention is: how to provide an underwater destruction device to solve the problem of safe and reliable destruction of objects to be destroyed.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] An underwater destruction device, the key of which is that it includes:

[0006] A shell, wherein an explosion assembly, an explosion-proof structure and an explosion-proof control circuit are arranged in the shell, wherein the explosion-proof structure has a safety locking state and a safety releasing state;

[0007] A fixing device, used to fix the object to be destroyed and the shell together;

[0008] The destruction device is fixed on the shell. When the explosion-proof safety structure is in the safety release state, the detonation component can be detonated through the detonation control circuit and detonated to the destruction device, and the destruction device is used to expand the explosion to destroy the objects to be destroyed.

[0009] By adopting the above scheme, the items to be destroyed can be connected to the shell through a fixing device and then placed in water. The items to be destroyed can be accurately detonated and destroyed in the target water depth environment through the explosion-proof structure and the detonation control circuit. The multiple insurance structures greatly improve the safety of the destruction operation.

[0010] Preferably, the detonating assembly comprises an electric detonator and explosive charge, the damaging device comprises an explosive expansion body and an explosive expansion column, and when the explosion-proof structure is in a safety locking state, the explosive charge is located between the electric detonator and the explosive expansion column, and the electric detonator and the explosive expansion column are directly opposite, and the explosive charge and the electric detonator are staggered;

[0011] The explosion-proof safety structure includes an explosion-proof rod and a hydraulic rod connected to one end of the explosion-proof rod. The explosive charge is arranged on the explosion-proof rod. A hydraulic diaphragm is fixedly sleeved on the hydraulic rod. After the device is put into water, the hydraulic diaphragm is able to push the explosion-proof rod to slide from a locked position to an unlocked position after the water pressure reaches the designed pressure value. The electric detonator, explosive charge and expansion charge column are aligned in sequence.

[0012] By adopting the above explosion-proof insurance structure, the water pressure after entering the water is fully utilized to control the position of the explosion-proof rod. By changing the elasticity of the water pressure diaphragm, that is, adjusting its pressure-bearing energy, the movement distance of the explosion-proof rod can be reasonably adjusted to meet the explosion-proof and detonation requirements of different depths.

[0013] Preferably, a pressure-bearing cavity is provided in the housing at a position corresponding to the hydraulic rod, and a sliding channel is provided at a position corresponding to the explosion-proof rod; one end of the hydraulic rod passes through the outer wall of the housing and is provided with a safety pin, and the other end passes through the pressure-bearing cavity and is connected to the explosion-proof rod;

[0014] The hydraulic rod is sleeved with a hydraulic spring, one end of which is against the hydraulic diaphragm, and the other end is against the inner wall of the pressure chamber. With the above solution, the safety pin can ensure the ground safety factor, and the hydraulic action restriction can only be released by releasing the safety pin. On the other hand, the hydraulic spring cooperates with the hydraulic diaphragm to achieve hydraulic protection, avoiding safety accidents caused by accidental touch.

[0015] Preferably, the housing has an operation panel that is detachably arranged, the inner side of the operation panel has a protrusion, and the pressure-bearing cavity is formed in the protrusion;

[0016] The inner side of the operation panel has a mounting seat connected to the raised portion, and the sliding channel is formed in the mounting seat. The above solution can realize modular disassembly and assembly, and improve the convenience of disassembly and assembly.

[0017] Preferably, a retaining structure is provided in the housing, and the retaining structure is used to keep the explosion-proof safety structure in a safety-released state. The above scheme can ensure that the detonation assembly can be normally detonated through the detonation control circuit when the detonation conditions are met, which is conducive to improving the detonation reliability.

[0018] Preferably, the detonation control circuit includes a charge and discharge control circuit connected to the electric detonator, and the electric detonator is equipped with a short-circuit switch. When the flameproof structure is in a safety locked state, the electric detonator is in a short-circuit state. When the flameproof structure is in a safety released state, the short-circuit switch is opened, and the electric detonator is released from the short-circuit state. The above scheme uses the flameproof structure to control the short-circuit switch, which is conducive to further improving the safety and reliability of the electric detonator detonation, and avoiding the occurrence of the electric detonator detonation when the flameproof state is not released.

[0019] Preferably, the detonation control circuit comprises a power supply circuit, and the power supply circuit comprises a power supply, a power-on switch and a knob switch;

[0020] The knob switch is a push-type knob switch, which is arranged on the housing and is used to open or close the power-on switch. With the above solution, the external knob switch is used to control the opening and closing of the power-on switch, thereby improving operability and reliability.

[0021] Preferably, the detonation control circuit includes a water environment detection circuit for determining whether the housing is in water, and the water environment detection circuit includes a detection terminal arranged on the surface of the housing. With the above solution, the water environment detection circuit is used to ensure that the water environment is one of the necessary conditions for the operation of the device, thereby avoiding the influence of air pressure and further improving safety.

[0022] Preferably, the detonation control circuit includes a water depth detection circuit for detecting the water depth of the device, and the water depth detection circuit includes a water pressure sensor arranged on the surface of the shell. With the above solution, the water depth detection circuit can better control the detonation water depth to meet the needs of detonation at different water depths.

[0023] As a preferred embodiment, the shell has a receiving cavity for installing the damaging device. With the above solution, the damaging device can be basically installed in the shell, which is conducive to improving the overall compactness and facilitating transportation, stacking, etc.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] The underwater destruction device provided by the present invention can accurately and safely destroy the objects to be destroyed underwater mainly through an ingenious explosion-proof structure and a detonation control circuit with multiple safety measures, thereby greatly improving its practicality, safety and reliability, and can be applied to a variety of objects to be destroyed, with good versatility.

[0045] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0046] refer to Figures 1 to 19 The underwater destruction device shown mainly includes a shell 100, a fixing device 200 and a damaging device 300, wherein the shell 100 is a sealed structure, and is provided with an initiating assembly 110, a flameproof structure 120 and a detonation control circuit therein, wherein the flameproof structure has a safety locked state and a safety released state, the fixing device 200 is mainly used to fix the object to be destroyed together with the shell 100, and the damaging device 300 is fixed on or inside the shell 100. In the present application, the fixing device 200 is a strap, and the shell 100 has a through hole for the strap to pass through. When the flameproof safety structure is in the safety released state, the initiating assembly can be detonated through the detonation control circuit, and the explosion can be directed to the damaging device 300, and the object to be destroyed can be destroyed by expanding the explosion using the damaging device 300.

[0047] As shown in the figure, the detonating assembly 110 mainly includes an electric detonator 111 and an explosive charge 112, and the damaging device 300 includes an explosive expansion body 310 and an explosive expansion column 311. When the explosion-proof structure is in a safety locked state, the explosive charge 112 is located between the electric detonator 111 and the explosive expansion column 311, and the electric detonator 111 is directly opposite to the explosive expansion column 311, and the explosive charge 112 and the electric detonator 111 are staggered.

[0048] The explosion-proof safety structure 120 includes an explosion-proof rod 121 and a hydraulic rod 122 connected to one end of the explosion-proof rod 121. The explosive charge 112 is arranged on the explosion-proof rod 121. A hydraulic diaphragm 123 is fixedly sleeved on the hydraulic rod 122. After the device is immersed in water, the hydraulic diaphragm 123 can push the explosion-proof rod 121 to slide from the locked position to the unlocked position after the water pressure reaches the designed pressure value, and the electric detonator 111, the explosive charge 112 and the explosive expansion column 311 are aligned in sequence.

[0049] A pressure chamber 130 is provided in the housing 100 at a position corresponding to the hydraulic rod 122 , and a sliding channel 140 is provided at a position of the explosion-proof rod 121 . One end of the hydraulic rod 122 passes through the outer wall of the housing 100 and is provided with a safety pin 124 , and the other end passes through the pressure chamber 130 and is connected to the explosion-proof rod 121 .

[0050] A hydraulic spring 125 is sleeved on the hydraulic rod 122 . One end of the hydraulic spring 125 abuts against the hydraulic diaphragm 123 , and the other end abuts against the inner wall of the pressure chamber 130 .

[0051] Specifically, the shell 100 has an operating panel 150 that is arranged in a detachable manner. The operating panel 150 is sealed and connected to the shell 100. The inner side of the operating panel 150 has a protrusion 151, and the pressure-bearing cavity 130 is formed in the protrusion 151. The inner side of the operating panel 150 has a mounting seat 160 connected to the protrusion 151, and the sliding channel 140 is formed in the mounting seat 160.

[0052] As shown in the figure, the mounting seat 160 is generally in the shape of a rectangular rod, the sliding channel 140 is a strip-shaped hole of the mounting seat 160, the electric detonator 111 is fixed on the mounting seat 160 and is connected with the sliding channel 140. In addition, the sliding channel 140 is connected with the pressure chamber 130, and a cover 131 is provided at a position corresponding to the pressure chamber 130 on the operating panel 150, and a connecting hole 132 is provided on the cover 131 and is connected with the pressure chamber 130.

[0053] The front end of the hydraulic rod 122 is connected to the explosion-proof rod 121, and the rear end is provided with a limit head 126, which passes through the sealing cover 131. The safety pin 124 is radially penetrated on the exposed part of the limit head 126 to limit the limit head 126 from sliding into the pressure chamber 130. The hydraulic spring 125 is sleeved on the hydraulic rod 122, and the hydraulic rod 122 has a sleeve structure. The rear end of the hydraulic spring 125 is located in the sleeve structure.

[0054] The middle part of the hydraulic diaphragm 123 is press-fitted onto the hydraulic rod 122 through the limit head 126, and is located between the limit head 126 and the sleeve structure, which can improve its installation efficiency. The circumferential outer edge of the hydraulic diaphragm 123 is fixed on the circumferential side wall of the pressure-bearing chamber 130. In this way, when the safety pin 124 is released and water enters the pressure-bearing chamber 130, the hydraulic diaphragm 123 is pressurized to overcome the elastic force of the hydraulic spring 125, and the hydraulic rod 122 can be pushed forward, thereby pushing the explosion-proof rod 121 to move forward.

[0055] When the electric detonator 111, the explosive charge 112 and the explosive expansion column 311 are aligned in sequence, the flameproof safety structure remains in the safety release state. In order to cooperate with other trigger conditions, it will not explode immediately at this time. Therefore, a holding structure is provided in the housing 100, which is used to keep the flameproof safety structure in the safety release state. Figure 3 , Figure 6 and Figure 8 In this embodiment, the retaining structure mainly includes a spring pin 161 arranged on the mounting seat 160, and a pin hole 127 opened on the explosion-proof rod 121. Initially, the pin hole 127 is located directly behind the spring pin 161. When the explosion-proof rod 121 slides from the locked position to the unlocked position, the pin hole 127 is aligned with the spring pin 161, and the spring pin 161 is inserted into the pin hole 127, thereby locking the position of the explosion-proof rod 121.

[0056] refer to Figure 3 and Figure 4In a specific implementation, the housing 100 has a housing cavity 170 for installing the damaging device 300. The housing cavity 170 is a relatively independent space inside the housing 100, and only has a through hole 171 for the explosive column 311 to pass through and communicate with the sliding channel 140. The explosive body 310 is located in the housing cavity 170 as a whole and cooperates with its thread, which can fully prevent the fluid from entering.

[0057] Key References Figures 9 to 19 In the present application, a circuit board 900 is installed on the inner side of the operation panel 150, and it is integrated into the operation panel 150 together with the flameproof structure 120, which is conducive to further realizing modular assembly and improving disassembly and assembly efficiency.

[0058] In this embodiment, the detonation control circuit is mainly arranged on the circuit board 900, and mainly includes a microcontroller 800, a power supply circuit 500, a charge and discharge control circuit 400 directly connected to the electric detonator 111, a boost circuit, a water environment detection circuit 600 and a water depth detection circuit 700. Fig.14 As shown, the microcontroller 800 also integrates modules such as a clock circuit, an analog-to-digital converter, and an IIC controller, and the operation panel 150 has a working status indicator light 153 and a fault status indicator light 152 connected to the microcontroller 800 .

[0059] Specifically, the power circuit includes a power supply 510 , a power switch 520 and a knob switch 530 . The knob switch 530 is a push-type knob switch, which is disposed on the housing 100 and is used to open or close the power switch 520 .

[0060] In this embodiment, the power source 510 is a battery, the power switch 520 is a push-type micro switch, and the knob switch 530 is disposed on the operation panel 150. Figures 8 to 10 As shown, the operation panel 150 has a sink 154 corresponding to the knob switch 530, and the sink 154 has two upper protrusions 1540 and two lower protrusions 1541 arranged opposite to each other. The upper protrusions 1540 and the lower protrusions 1541 are staggered, and a first restricted space 1542 is formed between the upper protrusions 1540 and the lower protrusions 1541, and a second restricted space 1543 is formed between the lower protrusions 1541 and the bottom wall of the sink 154. The first restricted space 1542 is formed between the upper protrusions 1540 and the lower protrusions 1541, and the second restricted space 1543 is formed between the lower protrusions 1541 and the bottom wall of the sink 154. The space 1542 and the second restricted space 1543 have notches 1544 arranged opposite to each other, and the knob switch 530 has a limiting protrusion 531, and the limiting protrusion 531 of the knob switch 530 can enter the first restricted space 1542 and the second restricted space 1543 through the notch 1544. After entering the corresponding space, the knob switch 530 is rotated to make the limiting protrusion 531 staggered with the notch 1544, so as to realize the axial limit of the rotating knob switch 530. Of course, the knob switch 530 should be equipped with a return spring during installation.

[0061] When the knob switch 530 is pressed down to the power-on position, the power-on switch 520 is closed, and power is supplied to the microcontroller 800 .

[0062] In this embodiment, the water environment detection circuit 600 is mainly used to determine whether the device is in water. As shown in the figure, the water environment detection circuit 600 is composed of a detection terminal 610, a capacitor, a resistor, a diode and an operational amplifier. The operational amplifier is used as a comparator circuit to test whether there is current conduction at both ends of the detection terminal, so as to determine whether it is in a water environment. The detection terminal 610 (shown as P2 in the circuit diagram) is also integrated and installed on the operation panel 150.

[0063] In this embodiment, the water depth detection circuit 700 is mainly used to detect the water depth of the device. The water depth detection circuit 700 is mainly composed of a capacitor, a resistor and a pressure sensor. The pressure value in the environment is detected by the pressure sensor D2, and the pressure data is then transmitted back to the microcontroller 800 through the IIC bus. The microcontroller 800 calculates the corresponding water depth based on the received pressure data. In specific implementation, the water pressure sensor 710 is also integrated and installed on the operation panel 150.

[0064] like Fig.16 As shown, in this embodiment, in order to obtain the large current required for detonation, a boost circuit is set up, which is mainly composed of a power chip N1, a capacitor, a resistor and an inductor. It should be noted that the boost circuit can be directly connected to the power supply 510, or the power supply line can be connected to the boost circuit after passing through the power-on switch, so that the boost circuit is also controlled by the power-on switch.

[0065] The charge and discharge control circuit 400 is used to directly feed a large current into the electric detonator 111. The electric detonator 111 is equipped with a short-circuit switch 410. When the explosion-proof structure is in a safety locked state, the electric detonator is in a short-circuit state. When the explosion-proof structure is in a safety released state, the short-circuit switch 410 is opened, and the electric detonator 111 is released from the short-circuit state. Figure 7 and Figure 8 As shown, the short-circuit switch 410 is installed on the mounting seat 160 and corresponds to the position of the sliding channel 140. When the explosion-proof rod 121 slides forward to the unlocking position, the short-circuit switch 410 is opened.

[0066] like Fig.19 As shown, the high voltage boosted by the boost circuit enters the charge and discharge control circuit 400, wherein R7 is much larger than R10. In this embodiment, R7 is 1kΩ, and R10 can be selected as 0Ω. The capacitor C8 is charged by the switch V1 controlled by the CapEn electrical signal. When the detonation condition is reached, the switch V4 is discharged by the CapEn2 electrical signal control. In the figure, P1 indicates an electric detonator, and P4 indicates a short-circuit switch protection.

[0067] refer to Figures 1 to 19The underwater destruction device shown in the figure, when stored, the explosion-proof rod 121 and the hydraulic rod 122 are locked by the safety pin 124 and cannot be pressed down and moved, and the explosive charge 112 therein is reliably isolated in the explosion-proof position, and even if the electric detonator explodes accidentally, it will not detonate and damage the device, and is in a safe explosion-proof state. At the same time, the short-circuit switch 410 connected to the electric detonator 111 is in a conducting state, and the electric detonator is short-circuited, ensuring the safety during basic maintenance and disposal.

[0068] When the destruction device is working, the main working process is as follows: the object to be destroyed is fixedly connected to the housing 100 through the fixing device 200. Specifically, the object to be destroyed is located opposite to the accommodating cavity 170, that is, close to the destruction device 300, and then the safety pin 124 is manually released.

[0069] a) Turn the knob switch 530 and press it to the upper potential, the control circuit is powered on and the control device is in working state. At this time, the battery voltage can be checked and displayed through the status indicator light.

[0070] b) The device carrying the items to be destroyed is thrown into the water, and the hydraulic diaphragm on the hydraulic safety rod is pressed down by the water pressure (the hydraulic diaphragm 123 and the hydraulic spring 125 can be optimized in the early stage to achieve the preset release of the explosion-proof pressure). When the target water depth is reached, that is, the target water pressure is reached, the explosion-proof rod 123 moves forward to its position, releasing the explosion-proof state and the short-circuit state of the electric detonator, and at the same time, it is kept in place by the retaining structure, and is always in the safety release state.

[0071] c) After the control module composed of the microcontroller 800 detects the water environment through the water environment detection circuit 600, it collects the underwater pressure through the water depth detection circuit 700 and calculates the water depth. In this embodiment, the preset water depth is greater than or equal to 10 meters.

[0072] d) When the water depth reaches a preset depth, the control module starts the detonation timing. After the delay time (the delay is 1 s in this embodiment), the detonation current is output to act on the electric detonator 111, which detonates the explosive 112 and the damaging device 300 in turn, thereby expanding the explosion and destroying the object A to be destroyed.

[0073] The above are only preferred implementations of the present invention. It should be pointed out that a number of modifications and improved technical solutions made by those skilled in the art without departing from the technical solution should also be deemed to fall within the scope of protection required by the claims.
