Description

Technical Field

[0001] This utility model belongs to the field of underwater operation equipment, specifically relating to an underwater target destruction device. Background Technology

[0002] Traditional methods for handling unexploded ordnance underwater typically involve transporting it to land for destruction or subjecting some explosive devices to cumbersome waterproofing treatments for underwater use. The former, involving moving the ordnance, obviously increases the risk and is inefficient; the latter, with its complex waterproofing process, hinders rapid maneuvering and cannot guarantee waterproofing performance, resulting in low safety. Both methods require a large amount of explosives, yet the results are often unsatisfactory.

[0003] Therefore, with the development of technology, some patents have emerged for this type of operation, such as the patent with patent number "CN109059698B" entitled "A Combined Unexploded ordnance shaped charge destroyer". The applicant found in his research that this type of product still has defects in reliability and safety. Utility Model Content

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is: how to provide an underwater target destruction device to solve the problem of poor reliability and safety of existing products.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] An underwater target destruction device includes a pressure-resistant housing, a working part disposed within the pressure-resistant housing, a fuse system, and a power supply. The key feature is that the fuse system includes a disarming device, a detonation controller, and an inline detonator. The disarming device includes a power-on control module and a water pressure control module, wherein the power-on control module includes a power-on switch.

[0007] The power-on switch includes a switch button exposed to the outside of the pressure-resistant housing, a release sleeve inside the pressure-resistant housing, and a switch contact rod located inside the release sleeve. The inner end of the switch contact rod is connected to a limit sleeve, and a micro switch is provided on the limit sleeve. The circumferential sidewall of the release sleeve has evenly distributed locking steel balls, and the switch contact rod has a steel ball groove.

[0008] In the initial state, the micro switch's switching piece is in the depressed position. When the switch button is pressed, the switch contact rod slides inward until the locking steel ball slides into the steel ball groove, at which point the micro switch's switching piece pops up, and the fuse system is powered on.

[0009] The above scheme mainly involves designing the power-on switch as a trigger mechanism, which can maintain the power-on state after power-on to avoid failure, thereby improving safety and reliability.

[0010] Preferably, the pressure-resistant housing includes a cylindrical body and an end cap, the end cap being sealed to the cylindrical body, the power switch being mounted on the end cap, and the switch button being equipped with a safety pin A. Adopting this solution can reduce the risk of accidental activation and further improve the safety factor.

[0011] Preferably, the end cap has an inner protrusion with a mounting cavity adapted to the switch button. The release sleeve is disposed in the mounting cavity. A switch spring is provided between the switch button and the release sleeve. A switch pressure plate is provided on the outside of the end cap corresponding to the switch button. In the initial state, the switch button abuts against the switch pressure plate under the action of the switch spring.

[0012] The switch button has a hollow structure, with the outer end of the switch contact rod extending into the switch button. This design results in a more compact overall structure and reduces sealing difficulties.

[0013] Preferably, a release spring is provided between the limiting sleeve and the inner protrusion. The micro switch is installed on the outside of the limiting sleeve. The release spring is a tension spring. In the initial state, under the action of the release spring, the limiting sleeve tends to move outward, and the micro switch abuts against the end face of the inner protrusion, with its switch piece in a pressed-down position. This design provides better reliability and prevents the micro switch from vibrating and causing its switch piece to spring back up for power-on when not in operation.

[0014] Preferably, the water pressure control module includes a water pressure sensor.

[0015] Preferably, the working part includes a hollow working part shell, one end of which is open as a charging port and equipped with a cap, and the other end is provided with a shaped charge shroud, which is conical with a cone angle of 60°-80°. Using this design, the jet can be formed more concentratedly, achieving a better concentrated damage effect.

[0016] Preferably, the detonation controller includes a trigger detonation module, which includes a trigger switch mounted on the pressure-resistant housing. The inner end of the trigger switch has a magnet, and a trigger detonation circuit board is located inside the pressure-resistant housing corresponding to the magnet. This trigger detonation circuit board has a Hall sensor. Using this solution, impact-triggered detonation can be performed when needed, meeting the requirements of multiple application scenarios.

[0017] Preferably, the trigger switch is equipped with a safety pin B. This design reduces the risk of accidental activation and further enhances safety.

[0018] Preferably, the power source is a battery pack composed of CR2 lithium-manganese dioxide single cells. This approach offers advantages such as high-rate discharge, high energy density, low self-discharge rate, and good safety, meeting the operational and storage environment requirements throughout the entire lifecycle of the deep-sea energy-concentrating device.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] The underwater target destruction device provided by this utility model mainly optimizes the safety and reliability of the disarming device, the detonation controller, and the working part, making it particularly suitable for deep-sea operations. Attached Figure Description

[0032] The present invention will now be described in further detail with reference to the accompanying drawings.

[0033] refer to Figures 1 to 11The underwater target destruction device shown mainly includes a pressure-resistant housing 100, a working section 200 disposed within the pressure-resistant housing 100, a fuse system 300, and a power supply 400. The power supply 400 is mainly used to supply power to the entire device. The fuse system 300 is mainly used to detonate the working section 200, and includes a safety release device 310, a detonation controller 320, and an inline detonator 330. The safety release device 310 is mainly used to prevent the fuse from activating under conditions other than receiving an underwater acoustic remote detonation command or the expiration of the delayed detonation time, ensuring the safety of personnel and equipment. The detonation controller is used to receive underwater acoustic remote control commands, delay detonation timing, detect and set parameters, manage power, and control the charging and detonation of the inline detonator 330. The inline detonator 330 is used to receive control signals from the detonation controller 320, complete energy conversion, and ultimately trigger the explosive charge in the working section. The safety release device 310 mainly includes a power-on control module and a water pressure control module, wherein the power-on control module includes a power-on switch 500.

[0034] like Figure 4 and Figure 5 As shown, the power-on switch 500 includes a switch button 510 exposed to the outside of the pressure-resistant housing 100, a release sleeve 520 inside the pressure-resistant housing 100, and a switch contact rod 530 located inside the release sleeve 520. The inner end of the switch contact rod 530 is connected to a limit sleeve 540, and a micro switch 550 is provided on the limit sleeve 540. The circumferential sidewall of the release sleeve 520 has evenly distributed locking steel balls 521, and the switch contact rod 530 has a steel ball groove 531.

[0035] In the initial state, the switch piece of the micro switch 550 is in the pressed position. When the switch button 510 is pressed and the switch contact rod 530 slides inward until the locking steel ball 521 slides into the steel ball groove 531, the switch piece of the micro switch 550 pops up, the power supply circuit of the power supply 400 is closed, and the whole device is in the powered-on state.

[0036] In this application, the pressure-resistant housing 100 adopts a split structure, which includes a generally columnar cylindrical body 110 and an end cap 120. The end cap 120 is sealed to the cylindrical body 110. The end cap 120 is provided with an underwater acoustic communication interface 124 and a detection preset port 125. The power switch 500 is installed on the end cap 120, and the switch button 510 is equipped with a safety pin A511.

[0037] As shown in the figure, the power switch 500 is located in the middle of the end cover 120. The inner side of the end cover 120 has an inner protrusion 121 that protrudes inward along its thickness direction. The inner protrusion 121 has a mounting cavity 122 that is adapted to the switch button 510. The release sleeve 520 is disposed in the mounting cavity 122. A switch spring 560 is provided between the switch button 510 and the release sleeve 520. A switch pressure plate 123 is provided on the outside of the end cover 120 corresponding to the switch button 510. In the initial state, the switch button 510 abuts against the switch pressure plate 123 under the action of the switch spring 560.

[0038] Specifically, the switch button 510 tends to move outward under the action of the switch spring 560 and abuts against the switch pressure plate 123, preventing it from sliding outward. At the same time, the switch button 510 has a hollow structure, and the outer end of the switch contact rod 530 extends into the switch button 510. At this time, the steel ball groove 531 is located inside the switch button 510, which is further away from the middle of the pressure-resistant housing 100 than the steel ball 521.

[0039] The switch contact 530 slides with the inner protrusion 121 and is provided with a radial sealing ring. A release spring 570 is provided between the limiting sleeve 540 and the inner protrusion 121, as shown in the figure. The limiting sleeve 540 slides with the reduced diameter section at the lower end of the inner protrusion 121. The lower end of the switch contact 530 is connected to the limiting sleeve 540 by a screw. The micro switch 550 is installed on the outside of the limiting sleeve 540. The release spring 570 is a tension spring. In the initial state, the limiting sleeve 540 is in contact with the release spring 570. When the switch button 510 is pressed down, it causes the limiting sleeve 540 to move outward. The micro switch 550 abuts against the end face of the inner protrusion 121, and its switch piece is in a pressed-down position. When the switch button 510 is pressed down, it causes the switch contact rod 530 to slide inward. When the steel ball groove 531 is facing the steel ball 521, the steel ball 521 is squeezed into the steel ball groove 531 by the switch button 510, which makes the switch contact rod 530 stuck. During this process, the limiting sleeve 540 slides inward together, which causes the switch piece of the micro switch 550 to pop up.

[0040] The water pressure control module in this application mainly includes a water pressure sensor 126 and a filter amplifier circuit. The water pressure sensor 126 is mounted on the end cover 120. The detonation controller 320 mainly includes a detonation timing module, an inline detonator interface, a microcontroller, a power management module, a trigger detonation module 340, an underwater acoustic communication signal module, and a detection preset module. The inline detonator 330 is connected to the detonation controller 320 through the inline detonator interface. The underwater acoustic communication signal module and the detection preset module are respectively connected to the underwater acoustic communication interface 124 and the detection preset port 125. The safety release device 310 is electrically connected to the detonation controller 320 and the inline detonator 330, and is also communicatively connected to the detonation controller 320.

[0041] like Figure 10As shown, the detonation timing module uses an RTC as a timer, and a parameter memory provides delay duration data. The charging signal drive circuit and the detonation signal drive circuit drive the connected inline detonator. The underwater acoustic communication signal module, the detection preset module, and the inline detonator interface are used to connect to external underwater acoustic communication equipment, detection preset equipment, and the inline detonator, respectively. The power management system provides power distribution for the entire detonation controller, and the microcontroller controls the aforementioned components.

[0042] The triggering module can send a signal to the microcontroller during the process of the deep-sea shaped charge damage device platform (not more than 50 kg) impacting the target shell (500 mm in diameter and 1 m in length) at a speed of not less than 0.1 m / s. After detecting the signal, the microcontroller controls the inline detonator to detonate the working part.

[0043] In this application, the working part 200 includes a hollow working part shell 210. One end of the working part shell 210 is open to form a charging port and is equipped with a cover 220. Explosive 250 can be filled into it through the charging port. The other end is provided with a shaped charge hood 230, which is conical with a cone angle of 60°-80°. In this embodiment, it is preferably 70°, which has a better explosive jet, good stability, and can avoid the formation of a reverse jet. The cylinder 110 is provided with a lower step 111 and an upper step 112 inside. One end of the working part shell 210 abuts against the lower step 111, and the other end is fixedly connected to the upper step 112 by screws.

[0044] In specific implementation, the shaped charge liner 230 is preferably supported by copper, which has better ductility. In addition, the working part 200 has a detonating charge 240 that contacts the fuse. The inline detonator 330 mainly includes a high-voltage module and an explosive foil detonator. Under external excitation and power supply, the high-voltage module boosts the low-voltage DC to high-voltage DC and stores the ignition energy in the capacitor C. After receiving the trigger excitation, it releases energy to the explosive foil detonator to complete the detonation. The detonating charge is then detonated by the initiating charge, which in turn detonates the explosive in the working part.

[0045] In specific implementation, the trigger detonation module 340 includes a trigger switch 341 disposed on the pressure-resistant housing 100. Specifically, the trigger switch 341 is disposed at the end away from the end cover 120. A trigger spring 345 and a switch pressure ring 346 are correspondingly disposed on the pressure-resistant housing 100. A magnet 342 is disposed at the inner end of the trigger switch 341. A trigger detonation circuit board 343 is disposed inside the pressure-resistant housing 100 corresponding to the magnet 342. The trigger detonation circuit board 343 has a Hall sensor. In the initial state, under the action of the trigger spring 345, the magnet 342 is relatively far away from the trigger detonation circuit board 343. After the trigger switch 341 is pressed, the magnet 342 approaches the trigger detonation circuit board 343. The Hall sensor is subjected to magnetic force and sends a detonation signal to the microcontroller. After the microcontroller detects the signal, it controls the detonation working part of the inline detonator.

[0046] To further enhance safety, the trigger switch 341 is equipped with a safety pin B344.

[0047] refer to Figure 7 and Figure 9 The safety release device is internally equipped with two isolation devices: INT1 and INT2, implemented by one P-MOSFET and one N-MOSFET. First, before the device is submerged, the power-on switch is manually pressed, sending a power-on signal to the drive circuit. The drive circuit then closes SW1 and SW2, powering on the safety release device and placing it in standby mode. Next, the microcontroller receives the electrical signal indicating separation between the device platform and the test platform. The first safety device, INT1, is then released, and a safety delay of N minutes (a preset time) Ts1 begins. After the safety delay Ts1 completes, the water pressure control module continuously measures the water depth. When the water depth exceeds D (in meters, a preset depth value), the second safety device, INT2, is released. Finally, the detonation controller, LDO2, is enabled, and the detonation controller begins timing according to the set safety delay Ts2 (M minutes, a preset time).

[0048] In this embodiment, the power supply 400 is a battery pack composed of CR2 lithium-manganese dioxide (Li-MnO2) single cells. In specific implementation, the battery pack uses three single cells connected in series to output V. O1 This output supplies power to the detonation device and detonation controller. It outputs V using two individual batteries connected in series. O2 This output supplies power to the inline detonator.

[0049] like Figure 11 As shown, in this embodiment, the inline detonator 330 mainly consists of a high-voltage module and an explosive foil detonator. Under external excitation and power supply, the high-voltage module boosts the low-voltage DC to high-voltage DC and stores the ignition energy in the capacitor C. After receiving the trigger excitation, it releases the energy to the explosive foil detonator to complete the detonation.

[0050] refer to Figures 1 to 11 The underwater target destruction device shown works on the following principle:

[0051] (a) Inspection and parameter setting. Before starting, the device is inspected and the safety delay (Ts2) and delayed detonation time (Ttrig) are set according to the mission requirements.

[0052] (b) Installation. Install the device on the mounting platform and remove safety pins A511 and B344.

[0053] (c) Manual power-on of the device. Before entering the water, press the power-on switch 500 to manually power on the device.

[0054] (d) Target search in water. The device travels with the platform to the vicinity of the target and completes target identification and alignment (the other supporting equipment completes the identification).

[0055] (e) The device is separated from the mounting platform.

[0056] (f) Disarm the first safety measure. After separating from the mounting platform, disarm the first safety measure INT1 and run for a safety delay of Ts1 (N minutes).

[0057] (g) Release the second safety device. Based on the water depth measured by water pressure, release the second safety device INT2 when the depth is greater than D, and run the safety delay Ts2 (M minutes).

[0058] (h) Waiting for detonation. If a "detonation" command is received via underwater acoustic remote control during the waiting period, the detonation controller will control the inline detonator to detonate the working part and destroy the target;

[0059] If no remote "detonation" command is received, the inline detonator will be controlled to detonate the working part after the delayed detonation time (Ttrig) ends, destroying the target;

[0060] If the device causes the trigger switch to strike the target housing at a speed of not less than S (unit: m / s, preset), the detonation module will trigger detonation, destroying the target and ending the mission.

[0061] The above are merely preferred embodiments of this utility model. It should be noted that any modifications and improvements made by those skilled in the art without departing from this technical solution should also be considered to fall within the scope of protection claimed in this claim.
