SUMMARY

[0005] The technical scheme adopted by the present application is as follows:

[0006] A kind of safety self-destruction device for underwater special platform, including self-destruction battery assembly, self-destruction initiator, impact plate detonator and micro-explosive warhead;

[0007] Self-destruction initiator and micro-explosive warhead are fixedly installed at the assembly charge of underwater special platform, and impact plate detonator is arranged between self-destruction initiator and micro-explosive warhead;Self-destruction device battery assembly is installed at the cable operation hole of underwater special platform, and self-destruction device battery assembly is connected with self-destruction initiator through cabin cable;The self-destruction battery assembly has independent safety, and is used for sensing water pressure after power supply of double-logic firmware circuit is removed;According to the posture of underwater special platform, water pressure setting is removed, and the sequence of self-destruction initiator is removed;Self-destruction initiator is removed by double-logic firmware circuit mode and double-logic circuit checking mode;By presetting the delay parameter of self-destruction initiator, underwater special platform is realized by timed detonation.

[0008] Further, the micro-explosive warhead adopts purple copper V-shaped cover.

[0009] Further, the impact plate detonator and self-destruction initiator adopt plug-in connection, and the pin pitch of impact plate detonator is not equal.

[0010] Further, the self-destruction battery assembly includes battery pack, water pressure sensor module, power control module, water pressure mechanism, safety pin and shell.

[0011] The safety pin is used to release the mechanical limit of the water pressure lever in the water pressure mechanism; the water pressure sensor module senses the water depth and transmits the depth information, and when the preset water pressure value is reached, the water pressure switch of the water pressure mechanism is turned on to supply power; the power supply control module is used for power supply control of the water pressure sensor module; the battery pack is independently powered for the entire assembly and powers the double-logic firmware circuit; the shell encapsulates the battery pack, the water pressure sensor module, the power supply control module, the water pressure mechanism and the safety pin.

[0012] Further, the power supply control module includes a switching circuit and a signal circuit;

[0013] The switching circuit is used to control the power-on and power-off of the water pressure sensor module; the signal circuit is used to transmit depth information and feedback the power consumption of each component of the self-destruction battery assembly.

[0014] A safety self-destruction method for an underwater special platform uses the safety self-destruction device described above, and the safety self-destruction method steps are as follows:

[0015] Step one, manually preset the delay parameters of the self-destruction initiator, and after successful setting, release the safety of the self-destruction battery assembly;

[0016] Step two, after the underwater special platform is launched, when the first set water depth is reached, the self-destruction battery assembly supplies power to the low-voltage logic module in the self-destruction initiator; when the attitude of the underwater special platform changes, the self-destruction initiator releases the first non-dynamic safety after a period of time;

[0017] Step three, when the self-destruction battery assembly senses a water depth greater than the second set water depth, the self-destruction initiator releases the second non-dynamic safety after a period of time;

[0018] Step four, the self-destruction initiator starts the safety timer, and after the safety timer reaches, the low-voltage logic module enters the depth judgment, if the depth continues to be less than the predetermined value, it is judged as abnormal floating, the last dynamic safety is released, the high-voltage logic module starts charging, and the impact disc detonator is detonated; otherwise, the self-destruction battery assembly stops power supply, and the safety self-destruction device enters the low-power consumption mode;

[0019] Step five, after the self-destruction timer time reaches, the self-destruction initiator releases the last dynamic safety, the high-voltage logic module starts charging, and the impact disc detonator is detonated, thereby detonating the micro-explosive warhead and detonating the underwater special platform.

[0020] Further, the safety of the self-destruction battery assembly is released by pulling out the safety pin; the water depth is sensed by the water pressure sensor module of the self-destruction battery assembly.

[0021] Beneficial effects:

[0022] 1、The present application relies on the mature technology of the in-line initiation device, and increases the self-destroying battery assembly on the basis of the design scheme, so that the whole device can be reliably powered on when the water depth is greater than the set water depth, and a series of safety release (posture, water pressure) timing is carried out, and finally the mine body is self-detonated. Moreover, the safety self-destroying device has no physical connection with other electrical equipment on the underwater special platform, and is an independent unit, which can realize the platform self-destroying function independently.

[0023] Secondly, by adopting the double logic firmware circuit mode and the double logic circuit checking mode, the redundant safety design is realized, and the risk of accidental release caused by single point failure is prevented.

[0024] Furthermore, the split structure design is adopted, the self-destroying battery assembly and the self-destroying initiator are physically isolated through the warehouse cable in the middle, and the reliability and applicability of the safety self-destroying device are improved.

[0025] 2、The present application optimizes the traditional aluminum U-shaped cover in the micro-explosive warhead to a red copper V-shaped cover, increases the initiation ability and initiation kinetic energy of the jet head, thereby improving the ability of the micro-explosive warhead to initiate the main charge, and enabling the underwater special platform to reliably self-detonate.

[0026] 3、The impact plate detonator and the self-destroying initiator are connected in a plug-in manner, and the pin pitch of the detonator is not equal, which can avoid misplug, facilitate quick installation and disassembly, and improve the supportability.

[0027] 4、The self-destroying battery assembly adopts independent safety design, avoids platform failure causing safety self-destroying device working failure, can ensure that the safety self-destroying device is reliably powered on and the safety is released, prevents safety risks caused by accidental action. Pulling out the safety pin can release the mechanical limiting of the water pressure rod, realize the closing power-on of the water pressure sensor module, the structure is simple and easy to realize, and the power-on mode of the water pressure sensor module during environmental simulation test is increased.

[0034] The self-destruction initiator 18 and the micro-explosive warhead 17 are fixedly installed at the charged position of the underwater special platform, the impact plate detonator 16 is arranged between the self-destruction initiator 18 and the micro-explosive warhead 17, the impact plate detonator 16 is connected to the self-destruction initiator 18 in a plug-in manner, and the four pin spacings of the impact plate detonator 16 are different.

[0035] The self-destruction battery pack 19 includes the battery pack 10, the water pressure sensor module 11, a power control module, a water pressure mechanism, the safety pin 12 and the battery pack shell 13.

[0036] As shown in the figure, Figure 2 , Figure 3 The safety pin 12 is used for releasing the mechanical limit of the water pressure rod in the water pressure mechanism, and the opening and closing of the water pressure switch can be realized by inserting / plugging the shaft end hole of the water pressure rod. The push spring 9 is sleeved on the water pressure rod. The water pressure sensor module 11 senses the water depth of the carried warhead and transmits the depth information to the circuit assembly 6 of the self-destruction initiator 18 through the signal circuit, and when the preset water pressure value is reached, the water pressure switch of the water pressure mechanism is closed.

[0037] The power control module is used for power supply control of the water pressure sensor module 11; the power control module includes a switching circuit and a signal circuit; the switching circuit is used for controlling the power-on and power-off of the water pressure sensor module 11; and the signal circuit is used for transmitting depth information and simultaneously feeding back the power consumption of each component of the self-destruction battery pack 19.

[0038] The battery pack 10 independently supplies power to the entire assembly and supplies power to the double-logic firmware circuit, which can meet the 21-day use requirement; and the battery pack shell 13 encapsulates the battery pack 10, the water pressure sensor module 11, the power control module, the water pressure mechanism and the safety pin 12.

[0040] One end of the detonator housing 5 is sealed by a top cover 7, which has a sealing connector 14 for connection to the cable 8; the other end is sealed by an output watertight end cover 4, which has a detonator socket 15 for connection to the impact detonator 16. The output watertight end cover 4 encapsulates the impact detonator 16. The circuit assembly 6 is located inside the detonator housing 5 and is used to control the deactivation, charging, and detonation functions of the entire device. It uses a dual-logic firmware circuit mode and a dual-logic circuit verification method to complete the deactivation. The circuit assembly 6 includes an attitude sensor. The self-destructing detonator 18 has a reserved internal communication interface, which can be connected to the detonation device detection equipment via a test cable to read the internal status, thus improving testability.

[0045] Step 2: After the underwater special platform is launched, when it reaches the first set water depth, the water pressure mechanism closes, and the self-destruct battery assembly 19 supplies power to the low-voltage logic module (including the attitude sensor) in its own water pressure sensor module 11 and self-destruct detonator 18; the attitude sensor senses that the attitude of the underwater special platform has changed, and after a period of time, the self-destruct detonator 18 releases the first non-dynamic safety.

[0046] Step 3: When the water pressure sensor module 11 detects a water depth greater than the second set water depth, the self-destruct detonator 18 will release the second non-dynamic safety device after a period of time.

[0047] Step four, the safety timing is started from the self-destruction initiator 18, after the safety timing reaches, the low pressure logic module enters the depth judgment, if the depth continues ≤5m, it is judged as abnormal floating, the last dynamic safety is removed, the high pressure logic module starts charging, and the impact plate detonator 16 is exploded; otherwise, the self-destruction battery assembly 19 stops power supply to the water pressure sensor module 11 and the attitude sensor, and the safety self-destruction device enters the low power consumption mode;

[0048] Step five, after the self-destruction timing time reaches, the self-destruction initiator 18 removes the last dynamic safety, the high pressure logic module starts charging, and the impact plate detonator 16 is exploded, then the charge column 2 of the micro-explosion warhead 17 is exploded, and the main charge of the underwater special platform or the platform shell is destroyed to make it sink to the bottom.
