TECHNICAL FIELD
[0001] The present application relates to the technical field of water vehicles, and particularly relates to an automatic opening and closing mechanism of a flow guide cap. BACKGROUND
[0002] Underwater blasting is an engineering technology that uses the energy generated by the explosion of explosives in water to complete specific tasks. This technology is not only suitable for the breaking of underwater rocks, but also can be used for the demolition and modification of underwater fixed or mobile structures. For underwater fixed structures, borehole blasting is relatively easy to implement and the technology is relatively mature. However, for mobile structures on the water surface or underwater (including ships, warships, boats, etc.), almost all of them use open blasting to perform blasting by the "shock wave" method from the outside to the inside. The energy utilization rate of this method is less than 20%, which is much lower than the energy utilization rate of the "expansion type" from the inside to the outside (the energy utilization rate of borehole blasting is greater than 95%). However, it is very difficult to perform drilling operations on mobile structures, and there is no relevant report so far.
[0003] In order to reduce the resistance and improve the navigability of the underwater bionic self-balancing navigation grabbing and drilling and blasting system when it navigates in water, the automatic opening and closing mechanism of the flow guide cap needs to be automatically closed. When it reaches the destination and prepares to perform the grabbing and drilling and blasting operation, the automatic opening and closing mechanism of the flow guide cap needs to be automatically opened to provide space for the negative pressure suction and powerful embedded anchor system and the independent feeding double-bit torque self-balancing drilling system. Therefore, it is necessary to propose an automatic opening and closing mechanism of the flow guide cap to solve the above technical problems. SUMMARY

[0007] Preferably, the plurality of flow guiding caps form a conical structure with a curved surface after being spliced and closed.
