The positioning columns and the positioning holes are slidably assembled.

[0035] The locking device 5 is an adjustable clamp, which is used to fix or release between the detonation reaction cavity 16 and the docking cylinder.

[0036] The gas injection unit includes a gas injection port 7, a pressurizing device 8, and an automatic and efficient gas injection device 9. The positions of the pressurizing device 8 and the automatic and efficient gas injection device 9 are relatively fixed with respect to the chassis 19. The gas injection port 7 is fixed outside the detonation reaction cavity 16 and the two are in communication with each other. The gas injection port 7 is located on the side close to the pre-explosion chamber 15. Gas pipes are fixedly connected and arranged between the output end of the automatic and efficient gas injection device 9 and the input end of the pressurizing device 8, and between the output end of the pressurizing device 8 and the port of the gas injection port 7. The pressurizing device 8 pressurizes the combustible gas provided by the automatic and efficient gas injection device 9 and injects it into the inside of the detonation reaction cavity 16 through the gas injection port 7.

[0037] The cavities of the gas injection port 7 and the internal cavity of the detonation reaction cavity 16 are both cylindrical, and the included angle between their axes is between 15° and 30°. The inner wall of the cavity of the detonation reaction cavity 16 is provided with spiral grooves like the vortex 6, so that when the mixed gas flows into the internal cavity of the detonation reaction cavity 16, a rotating fluid is generated, and the mixing efficiency of the combustible gas is increased by 50%.

[0038] A buffer component is also arranged outside the detonation reaction cavity 16.

[0039] A chassis locator 18 is arranged on the outer side of each all-terrain rubber tire, and the chassis locator 18 is assembled inside the chassis 19. The chassis locator 18 includes an internal thread sleeve, a threaded rod, and a turning wheel and a toothed footrest respectively fixed at the top and bottom of the threaded rod. By rotating the threaded rod through the turning wheel, the lifting height of the toothed footrest at its bottom can be adjusted.

[0040] Working principle: After the fragment 3 is sealed and installed, a methane-oxygen mixed gas (volume ratio 1:3 - 5) is injected into the internal cavity of the detonation reaction cavity 16, and the inflation pressure is 3 - 25 MPa. When the mixed gas is injected through the gas injection port 7, it is forced to swirl through the spiral groove-shaped vortex 6, so that the methane and oxygen are diffused at the molecular level and the mixing uniformity reaches 98% (detected by a gas chromatograph);

[0041] The detonator 13 is started, the excitation device 11 is remotely controlled through the remote control exciter 10, and the electric spark plug is ignited under the action of the connector 12. The electric spark plug ignites the local gas to form an initial detonation wave and propagates forward; the front-end detonation wave accelerates, and the rear-end reflected wave enhances the energy density. At this time, the detonation reaction occurs, and high-temperature and high-pressure energy is generated inside the detonation reaction cavity 16. When the detonation pressure reaches a certain value, the metal fragment 3 ruptures regularly along the V-shaped groove 14, releases high-pressure gas and excites the resonance of the detonation reaction cavity 16; the resonance frequency (simulated calculation is 8 Hz ± 2 Hz) is superimposed with the fragmentation noise of the fragment 3 to form a subsonic pulse with a main frequency of about 15 Hz. This subsonic wave can be released directionally. At the moment of detonation, the damping buffer 22 can automatically adjust the damping force through the pressure sensor signal. When the tail end of the damping buffer 22 contacts the recoil plate 21, it can suppress the vibration of the detonation reaction cavity 16 and maintain the stability of the chassis 19.

[0042] In this solution, the following purposes can be achieved:

[0043] 1. Directional energy release: The matching design of the pre-ignition position of the initiator 13 and the length of the detonation reaction cavity 16 (the length-diameter ratio is greater than 10:1) makes the detonation wave energy concentrated at the front end, reducing lateral loss;

[0044] 2. Controllable fragmentation structure: The grid of the V-shaped groove 14 makes the fragmentation size of the fragment 3 uniform (the average fragment area is 4 cm 2 ), reducing high-frequency noise interference and improving the purity of infrasound;

[0045] 3. Quick and repeated reloading: The quick-release and sealed design of the modular fragment 3 and the locking device 5 enables gas filling and replacement of the fragment 3 to be completed within 5 - 10 minutes;

[0046] 4. Through the collaborative design of the spiral mixing of the vortex 6 and the snap-in seal of the locking device 5, both the mixing efficiency and operation convenience are considered, breaking through the efficiency bottleneck of traditional devices.
