Description

Technical Field

[0001] This invention relates to the field of underwater navigation technology, and in particular to an automatic opening and closing mechanism for a flow deflector cap. 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 breaking 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 mobile structures on the surface or underwater (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 "expansion" energy utilization rate 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.

[0003] To reduce resistance and improve navigation of the underwater biomimetic self-balancing navigation grabbing and drilling / blasting system, an automatic opening and closing mechanism for the guide cap is required to close automatically. When the system reaches its destination and is ready to carry out grabbing and drilling / blasting operations, the automatic opening and closing mechanism for the guide cap needs to open automatically to make room for the negative pressure suction and powerful embedding anchoring subsystem and the independently fed dual-drill bit torque self-balancing drilling subsystem. Therefore, it is necessary to propose an automatic opening and closing mechanism for the guide cap to solve the above-mentioned technical problems. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the prior art by providing an automatic opening and closing mechanism for a flow guide cap.

[0005] An automatic opening and closing mechanism for a flow guide cap includes multiple flow guide caps, a flow guide cap control motor, a steel wire guide ring, multiple steel wire ropes, multiple springs, multiple steel wire fixing blocks, a flow guide cap control first pressure bearing, a flow guide cap control second pressure bearing, a flow guide cap control pressure bearing washer ring, a flow guide cap control pressure cover, and a flow guide cap control drive gear shaft, internal gear, and external gear. Each guide cap is fixedly connected to a guide cap rotating shaft via a guide cap rotating shaft. Each guide cap rotating shaft is rotatably connected to the front end of the suction cup housing. A spring is fixedly connected between each guide cap and the suction cup housing. The spring is used for the return and closure of the guide cap. After multiple guide caps are spliced ​​together, they can cover the front end of the suction cup housing. A steel wire guide ring is fixedly connected to the right side of the explosive projectile propulsion motor. A guide cap control cover is fixedly connected to the right side of the steel wire guide ring. Inside the steel wire guide ring, from left to right, are installed the guide cap control pressure bearing washer ring, the guide cap control first pressure bearing ring, and the guide cap control first pressure bearing ring. The bearing, internal gear, and guide cap control the second pressure bearing. The right side of the guide cap control of the second pressure bearing is attached to the left side of the guide cap control cover. Multiple steel wire fixing blocks are evenly distributed on the outer side of the internal gear. One end of each steel wire rope is fixedly connected to a steel wire fixing block. The other end of each steel wire rope passes through a steel wire guide ring and is fixedly connected to the outer side of each guide cap. The guide cap control motor is fixedly connected to the guide cap control cover. The guide cap control drive gear shaft connected to the guide cap control motor is fixedly connected to the external gear. The external gear meshes with the inner side of the internal gear.

[0006] Preferably, multiple flow guide caps are spliced ​​together and closed to form a conical structure with a curved surface.

[0007] Compared with existing technologies, the advantages of this system are: When the flow guide cap is closed, it has a curved, cone-shaped structure at the front end of the device, which can reduce system resistance and improve system navigation. When the device reaches the destination and is ready to carry out grabbing and drilling and blasting operations, the automatic opening and closing mechanism of the flow guide cap controls the flow guide cap to open through the flow guide cap control motor and other components, making room for the negative pressure suction and strong embedding anchoring subsystem and the independent feed dual drill bit torque self-balancing drilling subsystem.

Detailed Implementation

[0009] Referring to the accompanying drawings, an automatic opening and closing mechanism for a flow guide cap includes multiple flow guide caps 501, a flow guide cap control motor 502, a steel wire guide ring 503, multiple steel wire ropes 504, multiple springs 505, multiple steel wire fixing blocks 506, a flow guide cap control first pressure bearing 507, a flow guide cap control second pressure bearing 508, a flow guide cap control pressure bearing washer ring 509, a flow guide cap control pressure cover 510, a flow guide cap control drive gear shaft 511, an internal gear 512, and an external gear 513. Each guide cap 501 is fixedly connected to a guide cap rotating shaft 50102 via a guide cap rotating shaft support 50101. Each guide cap rotating shaft 50102 is rotatably connected to the front end of the suction cup housing. A spring 505 is fixedly connected between each guide cap 501 and the suction cup housing. The spring 505 is used for the reset and closure of the guide cap 501. After multiple guide caps 501 are spliced ​​together, they can cover the front end of the suction cup housing. A steel wire guide ring 503 is fixedly connected to the right side of the explosive projectile propulsion motor. A guide cap control cover 510 is fixedly connected to the right side of the steel wire guide ring 503. Inside the steel wire guide ring 503, from left to right, are installed the guide cap control pressure bearing washer 509, the guide cap control first pressure bearing 507, the internal gear 512, and the guide cap control... The second pressure bearing 508 is controlled by the flow guide cap. The right side of the second pressure bearing 508 is in contact with the left side of the flow guide cap control cover 510. Multiple steel wire fixing blocks 506 are evenly distributed on the outer side of the internal gear 512. One end of each steel wire rope 504 is fixedly connected to the steel wire fixing block 506. The other end of each steel wire rope 504 passes through the steel wire guide ring 503 and is fixedly connected to the outer side of each flow guide cap 501. The flow guide cap control motor 502 is fixedly connected to the flow guide cap control cover 510. The flow guide cap control drive gear shaft 511 connected to the flow guide cap control motor 502 is fixedly connected to the external gear 513. The external gear 513 meshes with the inner side of the internal gear 512. After multiple flow guide caps 501 are spliced ​​and closed, they form a conical structure with a curved surface.

[0010] Working principle of the invention: The opening process of the flow guide cap 501 is as follows: The flow guide cap controls the motor 502 to rotate in the forward direction. The motor 502, through the flow guide cap, controls the drive gear shaft 511 to drive the external gear 513 to rotate. When the external gear 513 rotates, it drives the internal gear 512 to rotate. When the internal gear 512 rotates, it drives the steel wire fixing block 506 to rotate. Since the steel wire guide ring 503 is fixed, when the steel wire fixing block 506 rotates, it pulls multiple steel wire ropes 504 to wrap around the outer ring of the internal gear 512. The left end of the steel wire ropes 504 will then be pulled... The guide cap 501 will rotate outward around the guide cap rotation shaft 50102. When the guide cap 501 rotates outward, it will pull the spring 505. The spring 505 is under tension, but the traction force of the wire rope 504 is greater than the tension force of the spring 505, so that the guide cap 501 can be rotated and opened. The function of the guide cap control first pressure bearing 507 and guide cap control second pressure bearing 508 is to support the internal gear 512 and realize the rotation of the internal gear 512. The closing process of the flow guide cap 501 is as follows: The flow guide cap controls the motor 502 to rotate in the opposite direction. The motor 502 controls the drive gear shaft 511 via the flow guide cap to drive the external gear 513 to rotate. When the external gear 513 rotates, it drives the internal gear 512 to rotate. When the internal gear 512 rotates, it drives the steel wire fixing block 506 to rotate. The steel wire rope 504 wrapped around the outer ring of the internal gear 512 gradually detaches. The spring 505 pulls the flow guide cap 501 to rotate inward around the flow guide cap rotation shaft 50102. The elastic force of the spring 505 is greater than the tension of the steel wire rope 504, so that the flow guide cap 501 returns to its initial state. After multiple flow guide caps 501 are closed, they can seal the front end of the suction cup shell and reduce the forward resistance of the system.
