Description

Technical Field

[0001] The present invention relates to the technical field of underwater vehicle jettisoning devices, and in particular to a jettisoning device suitable for underwater vehicles that is easy to disassemble, assemble and maintain. The device is suitable for various types of diving vehicles such as underwater navigating robots and aircraft, and is a jettisoning self-rescue device in an emergency. Background Art

[0002] As my country attaches great importance to the development of marine resources and accelerates the strategic layout, underwater submersibles of various forms and uses have appeared one after another. However, whether it is AUV (Autonomous Underwater Vehicle) or HOV (Human Occupied Vehicle), they face various risks when navigating underwater, such as internal mechanical or electronic failures, and other unpredictable emergencies. At this time, the most common and effective self-rescue measure for the submersible is to abandon heavy objects and float up.

[0003] At present, there are various designs of underwater submersible jettisoning devices at home and abroad, but most of them have complex structures, multiple action procedures, and the load generated by the jettisoned heavy objects on the action actuators is large. In addition, due to the structural form, it is not suitable to be made into a sealed form, and it is not convenient to reinstall the jettisoning vehicle. The subsequent disassembly and maintenance costs are high, and the practicality and stability are unsatisfactory.

[0004] Specifically, the existing dumping device has the following problems:

[0005] (1) Most of the existing methods for jettisoning underwater vehicles involve fixing the jettisoned weight on an actuator and changing the environment of the jettisoned weight through the action of the actuator. The jettisoning process will bring a large load to the actuator, causing structural deformation, jamming and other problems, increasing the risk of executing the jettisoning action.

[0006] (2) The existing jettisoning device actuator has a complex structure and its installation has high requirements for space and layout, which limits the maneuverability and flexibility of the underwater submersible jettisoning device and is not suitable for small submersibles.

[0007] (3) The existing dumping device has poor maintainability and requires manual disassembly and maintenance. Moreover, after being left for a long time, the flexibility and stability of the movement will be significantly reduced.

[0008] Therefore, how to provide a jettisoning device that is anti-deformation, flexible to install, easy to maintain, compact in structure and suitable for use with small underwater submersibles has become a problem that needs to be solved urgently. Summary of the invention

[0021] Further, the present invention is applicable to the jettisoning device of the underwater submersible, in which the loading mechanism 6: the shaft parts at both ends of the ratchet 601 pass through the right supporting wheel 603.a and the left supporting wheel 603.b respectively, the right supporting wheel 603.a and the left supporting wheel 603.b are fixedly connected to the ratchet 601 by at least one right fastening screw 608.a and the left fastening screw 608.b respectively, and the two ends of the shaft part of the ratchet 601 are connected to the right end cap 605.a of the ratchet and the left end cap 605.b of the ratchet respectively by the right end cap screw 606.a, the right end gasket 607.a and the left end cap screw 606.b, the left end gasket 607.b, and then assembled On the two ratchet brackets 403 of the hanging plate 4; the two ends of the J-shaped hook 610 are respectively connected through the J-shaped hook right end cap 611.a and the J-shaped hook left end cap 611.b by the J-shaped hook right end cap screw 613.a, the right spring washer 612.a and the J-shaped hook left end cap screw 613.b, the left spring washer 612.b, and then assembled on the two J-shaped hook brackets 402 of the hanging plate 4; the ring mouth 610.3 at the tail end of the J-shaped hook 610 is connected with the ring mouth at the tail end of the spring frame 404 through the double hook spring 614, so that the locking protrusion 610.1 of the J-shaped hook 610 can be used in conjunction with the small groove 601.1 and the large groove 601.2 of the ratchet 601.

[0022] Furthermore, the present invention is applicable to a jettisoning device of an underwater submersible, wherein in the jettisoning body 2: a lead cake 206 is pressed and fixed by a screw 204 and a nut 205, a T-shaped frame 202 is assembled on a steel shell 207 through a steel shell nut 203 below, and a pin 201 cooperates with a positioning groove 101 of a sealing shell 1, so that the jettisoning body 2 will not jump in the jettisoning body hole 102 of the sealing shell 1.

Before installing the jettisoning carrier 2, it is necessary to ensure that the locking protrusion 610.1 of the J-shaped hook 610 is locked in the small groove 601.1 of the ratchet 601. The purpose is to ensure that when the projectile carrier 2 is manually lifted to the projectile carrier hole 102 of the sealed shell 1, the upper horizontal end of the T-shaped frame 202 contacts the left supporting wheel spring piece 602.b and the right supporting wheel spring piece 602.a, and then the left and right supporting wheels drive the ratchet 601 to rotate upward in a circular motion synchronously, and the locking protrusion 610.1 slides from the small groove 601.1 to the large groove 601.2 and is stuck, so that the ratchet 601 is constrained by the J-shaped hook 610 at this time.
