Of course, the knob switch 530 should be installed with a reset spring.

[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 primarily used to detect the water depth of the device. It primarily consists of a capacitor, a resistor, and a pressure sensor. Pressure sensor D2 detects the current ambient pressure and transmits this pressure data back to the microcontroller 800 via the IIC bus. The microcontroller 800 calculates the corresponding water depth based on the received pressure data. In specific implementations, the water pressure sensor 710 is also integrated into the operation panel 150.

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 send a large current to the electric detonator 111. The electric detonator 111 is equipped with a short-circuit switch 410.

When the explosion-proof rod 121 slides forward to the unlocking position, the short-circuit switch 410 is opened.

In this embodiment, R7 is 1 kΩ, and R10 can be selected as 0 Ω. The capacitor C8 is charged by the switch V1 controlled by the CapEn electrical signal. When the detonation condition is met, the switch V4 is discharged by the CapEn2 electrical signal control.

At the same time, the short-circuit switch connected to the electric detonator 111 is in an on state, the electric detonator is short-circuited, and the safety during basic maintenance is ensured.

[0068] When the destruction device is working, the main working process is as follows: the fixed device 200 is used to fix and connect the to-be-destroyed product with the shell 100, specifically, the to-be-destroyed product is opposite to the position of the accommodating cavity 170, that is, adjacent to the destruction device 300, and then the safety pin 124 is manually released.

[0069] Turn the knob switch 530 and press it to the upper potential, the control circuit is powered on, the control module is in a working state, at this time, the battery voltage can be checked, and the state display lamp is displayed.

[0070] The equipment carrying the to-be-destroyed product is thrown into the water, the water pressure diaphragm of the water pressure safety rod is pressed under the pressure of water (the pre-set of the explosion-proof pressure can be achieved by optimizing the water pressure diaphragm 123 and the water pressure spring 125), when the target water depth is reached, that is, the target water pressure is reached, the explosion-proof rod 123 is moved forward to the position, the explosion-proof state and the electric detonator short-circuit state are released, and at the same time, it is kept in the position by the retaining structure, and is always in the safety release state.

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

[0072] When the water depth reaches the preset depth, the control module starts the detonation timing, and after the delay time (the delay time in the embodiment is 1s) the detonation current is output to the electric detonator 111, the booster 112 and the destruction device 300 are detonated in turn, so that the to-be-destroyed product A is expanded and destroyed.

[0073] The above is only the preferred embodiment of the present application, it should be pointed out that for the technical solutions of several deformations and improvements made by the person skilled in the art without departing from the technical solutions, they should also be considered to fall within the scope of protection claimed in the present application.
