Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of underwater vehicles, and in particular relates to a locking and releasing mechanism for a slewing body anchor. Background Art
[0002] In actual marine engineering applications, the residence of AUVs can be divided into two types: benthic and anchored. The benthic type uses a buoyancy adjustment mechanism and a support frame to enable the AUV to moor on the seabed, while the anchored type uses an underwater winch to drive the anchor chain, and the towing power of the AUV anchors the anchor on the seabed. Unlike traditional anchors, the rotary self-tapping anchor can enter or exit the seabed mud through the forward and reverse rotation of its own structure, greatly increasing the number of tasks that the AUV can complete in a single voyage. The locking and release of the rotary anchor structure often adopts the form of a latch, a ring, etc., and the locking force is provided by an electric push rod or a motor. The cylindrical structure is used for storage. The structure is complex and the shape of the rotary anchor needs to be changed. At the same time, there is currently little research on the mounting method of the rotary anchor on the bottom of the AUV, so there is an urgent need for a storage, fixing and release device suitable for the rotary self-tapping anchor.

DETAILED DESCRIPTION
[0015] The specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that those skilled in the art can more clearly understand how to practice the present invention. Although the present invention is described in conjunction with its preferred specific embodiments, these embodiments are only illustrative and are not intended to limit the scope of the present invention.
[0016] A locking and releasing mechanism for a rotary body anchor comprises a spring sleeve 1, an electromagnet sleeve 2, a sleeve fixing plate 3, a transmission plate 4, a rotary body anchor 9, a bottom plate 10, a locking block 12, a transmission lever 6, a transmission lever shaft 5 and a locking ring 8. The spring sleeve 1 and the electromagnet sleeve 2 are both mounted on the sleeve fixing plate 3 and are installed by two sets of 4-M4×6 hexagon socket screws. The transmission plate 4 is arranged at the bottom of the spring sleeve 1 and the electromagnet sleeve 2. The sleeve fixing plate 3 is connected to the locking block 12 by a locking ring 8. It is installed on the base plate 10 through a group of 4-M4×6 hexagon socket screws. Locking ring shafts 7 are symmetrically arranged on both sides of the locking ring 8. A slewing body anchor 9 is arranged in the locking ring 8. A locking ring mounting seat 14 is symmetrically installed at the bottom of the base plate 10 and fixed by M4 hexagon socket screws. The locking ring shaft 7 is rotatably connected to the locking ring mounting seat 14. The transmission plate 4 is connected to the transmission lever 6 through screws, and the transmission lever 6 is rotatably installed on the transmission lever shaft 5.
[0017] The spring in the spring sleeve 1 is a compression spring, and the stiffness of the compression spring can be adjusted according to the motion state of the transmission lever 6 in the actual environment. The present invention uses a combination of an electromagnet and a compression spring to complete the locking and closing instructions to achieve the locking and release of the rotary anchor 9.
[0018] Specifically, the transmission lever shaft 5 is provided with a rotating sleeve 16 , and both ends of the rotating sleeve 16 are mounted on the base plate 10 through a lever mounting seat 15 .
[0019] Specifically, the locking ring 8 is symmetrically arranged as two semi-circular arc rings, the inner diameter of the semi-circular arc ring is slightly larger than the outer diameter of the rotating body anchor 9, and the semi-circular arc ring is used to clamp the rotating body anchor 9.
[0020] Specifically, a roller shaft 13 is provided at one end of the semicircular arc ring, and a locking rubber roller 11 is provided on the outer sleeve of the roller shaft 13. The locking block 12 is arranged between the locking rubber rollers 11. The locking block 12 is connected to one end of the transmission lever 6. The locking block 12 between the two semicircular arc rings is used to suppress the rotation of the locking ring 8. The locking rubber roller 11 of the locking ring 8 is pressed against the locking block 12 by the gravity of the rotating body anchor 9, and the pressure direction is perpendicular to the two surfaces of the locking block 12, so that it completes self-locking.
[0021] Specifically, the electromagnet of the electromagnet sleeve 2 is of the energized and demagnetized type. When not energized, its magnetic force is much greater than the pre-stressed elastic force of the spring in the spring sleeve 1, so that the transmission plate 4 can be tightly attached to the surface of the electromagnet sleeve 2, and the locking block 12 is clamped by the left and right locking rubber rollers 11, thereby inhibiting the inward rotation of the locking ring shaft 7.
[0022] Specifically, when the electromagnet of the electromagnet sleeve 2 is not energized, since the magnetic force of the electromagnet is much greater than the elastic force generated by the compression deformation of the spring, the bottom of the electromagnet sleeve 2 is close to the transmission plate 4, the transmission lever 6 remains stationary, and the locking block 12 is fixed, thereby inhibiting the locking ring 8 from rotating inward.
[0023] Specifically, when the electromagnet of the electromagnet sleeve 2 is energized, the electromagnet loses its magnetic force, and under the action of the spring force, the bottom of the spring sleeve 1 is close to the transmission plate 4 and pushes the transmission plate 4 to move downward, and the transmission lever 6 rotates upward around the transmission lever shaft 5, driving the locking block 12 to move upward and disengage from the locking rubber roller 11.
[0024] Specifically, the locking block 12 and the locking rubber roller 11 are both made of rubber material with a relatively small friction coefficient, so as to reduce the influence of friction and the elastic force required by the spring.
[0025] The specific working principle of the present invention is: When the electromagnet loses power, the magnetic force of the electromagnet is much greater than the elastic force generated by the compression deformation of the spring. Under the action of the magnetic force, the bottom end of the electromagnet sleeve 2 is tightly attached to the transmission plate 4. In this state, the transmission lever 6 remains stationary and the locking block 12 is fixed. The locking ring 8 is inhibited from rotating inward, and the locking rubber roller 11 cannot move after contacting the locking block 12, thereby completing self-locking, and the rotary body anchor 9 is locked.
[0026] When the electromagnet is energized, the electromagnet loses its magnetic force, and the transmission lever 6 is pushed upward by the spring force, and the transmission lever 6 rotates around the transmission lever shaft, that is, the end of the transmission lever 6 connected to the locking block 12 drives the locking block 12 to move upward until it is completely separated from the two locking rubber rollers 11. At this time, the locking rubber rollers 11 are no longer blocked, and under the action of the gravity of the swivel anchor 9, the locking ring 8 rotates outward until the opening exceeds the maximum diameter of the swivel anchor 9, so that it is completely separated, and the swivel anchor 9 is released.
[0027] The above description is only a preferred implementation manner of the present invention, but the protection scope of the present invention is not limited thereto, and any modification and replacement based on the technical solution and inventive concept provided by the present invention should be included in the protection scope of the present invention.
