AI Technical Summary
Existing technologies for drilling and blasting on underwater mobile structures have low energy utilization and make it difficult to effectively guide and propel explosive charges, especially on moving targets such as ships, vessels, and boats.

Abstract
Description
Technical Field
[0001] This invention relates to the field of underwater blasting technology, and more particularly to an explosive charge guidance and propulsion system. Background Technology
[0002] Underwater blasting is an engineering technique that utilizes the energy generated by the explosion of explosives in water to accomplish specific tasks. This technique is applicable not only to the breaking of underwater rocks but also to the demolition and modification of fixed or mobile underwater structures. For fixed underwater structures, drilling blasting is relatively easy to implement and the technology is relatively mature. However, for surface or underwater mobile structures (including ships, vessels, and boats), open-blasting is almost always used, employing an "outer shock wave" method to demolish them. This method has an energy utilization rate of less than 20%, far lower than the energy utilization rate of the "expansion" method of drilling blasting (which has an energy utilization rate of over 95%). However, drilling operations on mobile structures are very difficult, and no relevant reports have been found to date. After the independently fed dual-bit torque self-balancing drilling system completes drilling, it is necessary to push the explosive charge and its fuse from the underwater biomimetic self-balancing navigation grabbing and blasting system into the borehole to carry out the blasting operation. Therefore, it is necessary to invent an explosive charge guidance and propulsion system. Summary of the Invention
[0003] The purpose of this invention is to address the shortcomings of the prior art by proposing an explosive charge guidance and propulsion system.
[0004] An explosive charge guidance and propulsion system includes an explosive charge, an explosive charge propulsion motor, an explosive charge guide joint, and an explosive charge guide rod. The left side of the explosive projectile guide joint is fixedly connected to the drilling cover, and the right side of the explosive projectile guide joint is fixedly connected to the explosive projectile propulsion motor. The explosive projectile is installed inside the second pressure regulating shaft. The explosive projectile guide joint is also provided with an explosive projectile guide rod extending along the direction of the threaded shaft of the explosive projectile propulsion motor. The explosive projectile is threadedly connected to the threaded shaft of the explosive projectile propulsion motor and slidably connected to the explosive projectile guide rod. The explosive projectile can slide out from the inner drill bit joint and the inside of the inner drill bit along the explosive projectile guide rod.
[0005] Compared with existing technologies, the advantages of this system are: The explosive charge and its fuse in the underwater bionic self-balancing navigation grabbing and blasting system are rapidly pushed into the borehole by the explosive charge propulsion motor after the drilling work is completed. Attached Figure Description
[0006] Figure 1 This is a cross-sectional view of the present invention; In the picture: 401: Explosive projectile; 402: Explosive projectile propulsion motor; 403: Explosive projectile guide joint; 404: Explosive projectile guide rod; 405: Drilling cover; 406: Second pressure regulating shaft. Detailed Implementation
[0007] Referring to the accompanying drawings, an explosive charge guidance and propulsion system includes an explosive charge 401, an explosive charge propulsion motor 402, an explosive charge guide joint 403, and an explosive charge guide rod 404. The left side of the explosive projectile guide joint 403 is fixedly connected to the drilling cover 405, and the right side of the explosive projectile guide joint 403 is fixedly connected to the explosive projectile propulsion motor 402. The explosive projectile 401 is disposed inside the second pressure regulating shaft 406. The explosive projectile guide joint 403 is also provided with an explosive projectile guide rod 404 extending along the threaded shaft of the explosive projectile propulsion motor 402. The explosive projectile 401 is threadedly connected to the threaded shaft of the explosive projectile propulsion motor 402 and slidably connected to the explosive projectile guide rod 404. The explosive projectile 401 can slide out from the inner drill bit joint and the inside of the inner drill bit along the explosive projectile guide rod 404.
[0008] Working principle of the invention: After drilling is completed, the threaded shaft of the explosive projectile propulsion motor 402 begins to rotate. Since the end of the explosive projectile 401 is placed in the groove of the explosive projectile guide joint 403, and the explosive projectile 401 is threadedly connected to the threaded shaft of the explosive projectile propulsion motor 402 and slidably connected to the explosive projectile guide rod 404, the rotation of the threaded shaft of the explosive projectile propulsion motor 402 will drive the explosive projectile 401 to move continuously along the threaded shaft and the guide rod 404, eventually sliding out from the inner drill bit joint and the inside of the inner drill bit and into the borehole. At this time, it is only necessary to detonate the explosive projectile 401.
