Description

Technical Field

[0001] The present invention relates to the technical field of underwater vehicles, and in particular to an underwater vehicle shroud installation mechanism and an installation and disassembly method thereof. Background Art

[0002] The ocean is a valuable asset and potential for sustainable development for human society, rich in biological and mineral resources. As a crucial tool for ocean development, underwater vehicles (UVs) have experienced rapid development and are playing an increasingly important role in the sustainable utilization of marine resources. The shroud is a crucial component of an underwater vehicle, ensuring its streamlined appearance and providing protection for its internal equipment.

[0003] With the development of technology, higher requirements are being placed on the testability, maintainability, and security of underwater vehicles. The internal equipment of underwater vehicles needs to be tested and maintained according to regulations during use. This requires the shroud to be able to be quickly disassembled and assembled to shorten testing and maintenance time and improve the overall operational efficiency of the underwater vehicle. Currently, in existing technologies, shrouds are typically installed and fixed using a traditional bolted connection method. Multiple mounting holes are provided on the shroud, which is then bolted to a carrier frame or bracket. This installation and fixing method requires many tools, is time-consuming, and has low assembly and disassembly efficiency. This is especially true in high sea conditions, where the surface platform shakes violently, further exacerbating the difficulty of assembly and disassembly with this installation and fixing method, and even rendering the shroud impossible to disassemble and assemble, hindering the testing, maintenance, and overall operational efficiency of the underwater vehicle. Summary of the Invention

[0004] In response to the shortcomings of the above-mentioned existing production technology, the applicant provides an underwater vehicle fairing installation mechanism and an installation and disassembly method thereof, so that the fairing can be quickly removed and installed without the need for disassembly tools. It has strong environmental adaptability, effectively improves the testing and maintenance efficiency of the underwater vehicle, and further improves the overall operating efficiency of the underwater vehicle.

[0005] The technical solutions adopted in the present invention are as follows:

[0006] A shroud mounting mechanism for an underwater vehicle comprises a frame structure for the underwater vehicle, wherein a plurality of mounting rings are spaced apart on the frame structure, a shroud is mounted between two adjacent mounting rings, and a first limiting mechanism and a second limiting mechanism are mounted between a single shroud and the mounting ring;

[0007] The mounting ring is provided with a circumferential limiting ring and a radial limiting ring, a locking conical groove is provided at the apex of the radial limiting ring, and a limiting groove is provided on the side;

[0008] The No. 1 limit mechanism includes a housing, a locking rod, and a No. 1 spring. The housing is fixed to the top of the air deflector. The locking rod includes a rod body, a locking head, a sliding boss, and an L-shaped handle. The locking head is provided at the head of the rod body, the sliding boss is provided at the tail of the rod body, and the end of the sliding boss is provided with an L-shaped handle. The locking rod moves axially along the housing, and the action of the No. 1 spring causes the locking head to engage with the locking tapered groove of the mounting ring.

[0009] The air guide cover is provided with an inserting boss;

[0010] The No. 2 limiting mechanism is arranged in the limiting groove, including a No. 2 spring and a limiting block. The end of the air deflector is inserted into the limiting groove, and the wedge surface of the limiting block and the inclined surface of the insertion boss form a limiting fit through the action of the No. 2 spring.

[0011] Its further technical solution is:

[0012] The mounting ring adopts an integrated structure.

[0013] The mounting ring is a part of the underwater vehicle carrier structure and is the mounting base of the fairing, providing a mounting base surface for the fairing.

[0014] The locking head is a conical structure.

[0015] There are two sets of No. 1 limit mechanism.

[0016] Symmetrical rectangular holes are opened on the air deflector, and one end of the L-shaped handle of the No. 1 limiting mechanism is in the rectangular hole.

[0017] There are two sets of No. 2 limiting mechanisms, which are arranged symmetrically about the middle longitudinal section of the fairing.

[0018] The cross section of the limiting block is a trapezoidal structure, and a wedge-shaped surface is provided on one side of the limiting block.

[0019] A method for installing and disassembling a shroud installation mechanism for an underwater vehicle comprises the following steps:

[0020] Pull the L-shaped handle in the direction of the middle cross section of the air guide cover to drive the locking rod to move along the circumference of the shell until the locking head fits into the shell;

[0021] Then, place the air deflector on the mounting ring, insert the insertion boss into the limiting groove, and the limiting block presses against the insertion boss under the action of the second spring. The wedge-shaped surface of the limiting block and the inclined surface of the insertion boss form a limiting fit to form a radial limit for the end point of the air deflector;

[0022] Then, release the L-shaped handle, the locking rod moves along the circumference of the housing, and the locking head enters the locking tapered groove, forming a locking fit and generating a locking force;

[0023] The locking force can be decomposed into circumferential locking force and radial locking force. The circumferential locking force cooperates with the circumferential limiting ring of the mounting ring to form a circumferential limit for the entire air deflector; the radial locking force cooperates with the radial limiting ring of the mounting ring to form a radial limit for the apex of the air deflector.

[0024] The top and bottom endpoints of the air deflector shroud form a plane, and the radial limits at the three points constitute the radial limits of the entire air deflector shroud;

[0025] Finally, the first and second limiting mechanisms work together to balance the force on the shroud, forming circumferential and radial limits on the entire shroud, completely restricting the movement and rotation of the shroud, and fixing the shroud on the mounting ring.

[0026] (2) Disassembly process:

[0027] First, pull the L-shaped handle in the direction of the middle cross section of the air guide cover to drive the locking rod to move along the circumference of the shell until the locking head completely moves out of the locking tapered groove, and the locking fit is released;

[0028] At the same time, the air deflector is lifted upwards, and the limit block forms an upward lifting force on the air deflector under the action of the second spring, and the insertion boss moves out of the limit groove, and the limit fit at the end of the air deflector is released, and the air deflector is completely unrestricted;

[0029] That is to complete the quick disassembly of the air deflector.

[0030] The beneficial effects of the present invention are as follows:

[0031] The present invention has a compact and reasonable structure and is easy to operate. Through the mutual cooperation between components such as the installation ring, the fairing, the locking rod, the No. 1 limit mechanism and the No. 2 limit mechanism, the fairing can be quickly removed and installed without the need for disassembly and assembly tools. It has strong environmental adaptability, effectively improves the testing and maintenance efficiency of the underwater vehicle, and further improves the overall operating efficiency of the underwater vehicle.

[0032] The apex and bottom endpoints of the shroud described in the present invention form a plane, and the radial limits at these three points constitute radial limits for the entire shroud. The first and second limiter mechanisms work together to achieve force balance on the shroud, forming circumferential and radial limits for the entire shroud, completely restricting its movement and rotation and securing it to the mounting ring. The present invention allows for rapid removal and installation of the shroud without the need for tools, has strong environmental adaptability, effectively improves the testing and maintenance efficiency of underwater vehicles, and further enhances the overall operational efficiency of underwater vehicles.

[0033] At the same time, the present invention also has the following advantages:

[0034] (1) The present invention achieves force balance on the air deflector through the cooperation between the limiting mechanisms without the need for fasteners, forms a limit on the movement and rotation of the air deflector, and realizes installation and fixation on the mounting ring;

[0035] (2) The present invention does not require the use of tools during the disassembly and assembly of the shroud, and can quickly complete the disassembly and installation of the shroud, which saves time and has high disassembly and assembly efficiency, effectively improving the testing and maintenance efficiency of the underwater vehicle;

[0036] (3) The present invention can quickly complete the removal and installation of the deflector cover even in high sea conditions, and has strong environmental adaptability;

[0037] (4) The present invention has high integration and small operating space requirements, effectively improving the testing and maintenance space utilization of underwater vehicles. BRIEF DESCRIPTION OF THE DRAWINGS

[0062] The air guide cover 2 is provided with an inserting boss 201;

[0063] The No. 2 limiting mechanism is arranged in the limiting groove 104, including the No. 2 spring 6 and the limiting block 7.

[0069] There are two sets of No. 2 limiting mechanisms, which are arranged symmetrically with respect to the middle longitudinal section of the air deflector 2 .

[0070] The cross section of the limiting block 7 is a trapezoidal structure, and a wedge-shaped surface 701 is provided on one side of the limiting block 7 .

[0071] The specific structure and function of the quick-detachable underwater vehicle deflector mounting mechanism of the present invention are as follows:

[0072] It mainly includes a mounting ring 1, a No. 1 limiting mechanism 8 and a No. 2 limiting mechanism.

[0073] There are two sets of No. 2 limiting mechanisms, which are symmetrically arranged with respect to the middle longitudinal section of the air deflector 2 .

[0074] The mounting ring 1 is part of the underwater vehicle's carrier structure and serves as the mounting base for the shroud 2, providing a mounting surface for the shroud 2. The mounting ring 1 is equipped with a circumferential retaining ring 103 and a radial retaining ring 101. A locking tapered groove 102 is provided at the apex of the radial retaining ring 101, and a retaining groove 104 is provided on the side.

[0075] The first limiting mechanism 8 comprises a housing 4, a locking rod 3, and a first spring 5, secured to the top of the air scoop 2 via the housing 4. The locking rod 3 comprises a rod body 301, a locking head 302, a sliding boss 303, and an L-shaped handle 304. The locking head 302 is conical and located at the head of the locking rod 3, the sliding boss 303 is located at the tail of the locking rod 3, and the L-shaped handle 304 is located behind the sliding boss 303. The locking rod 3 is movable axially along the housing 4, and the first spring 5 forces the locking head 302 into a locking engagement with the locking tapered groove 102 on the mounting ring 1.

[0076] The second limiting mechanism includes a second spring 6 and a limiting block 7, which are arranged in the limiting groove 104. When the end of the air deflector 2 is inserted into the limiting groove 104, the wedge surface 701 of the limiting block 7 and the inclined surface of the insertion boss 201 are engaged by the action of the second spring 6 to form a limiting fit.

[0077] The working principle of the underwater vehicle deflector installation mechanism that can be quickly disassembled and assembled in the present invention is as follows:

[0078] (1) Installation of air deflector 2:

[0079] When installing the air deflector 2, pull the L-shaped handle 304 in the direction of the middle cross-section of the air deflector 2, driving the locking rod 3 to move along the circumference of the housing 4 until the locking head 302 is in contact with the housing 4. Place the air deflector 2 on the mounting ring 1, insert the insertion boss 201 into the limiting groove 104, and the limiting block 7, under the action of the No. 2 spring 6, presses against the insertion boss 201. The wedge-shaped surface 701 of the limiting block 7 and the inclined surface of the insertion boss 201 form a limiting fit, forming a radial limit for the end points of the air deflector 2. Release the L-shaped handle 304, and the locking rod 3 moves along the circumference of the housing 4, and the locking head 302 enters the locking tapered groove 102, forming a locking fit and generating a locking force. The locking force can be decomposed into a circumferential locking force and a radial locking force. The circumferential locking force cooperates with the circumferential limiting ring 103 of the mounting ring 1 to form a circumferential limiting of the entire air deflector 2; the radial locking force cooperates with the radial limiting ring 101 of the mounting ring 1 to form a radial limiting of the apex of the air deflector 2. The two endpoints of the apex and the bottom of the air deflector 2 form a plane, and the radial limiting at the three points constitutes the radial limiting of the entire air deflector 2. Through the joint action of the No. 1 limiting mechanism 8 and the No. 2 limiting mechanism, the air deflector 2 reaches a force balance, forming a circumferential limiting and radial limiting of the entire air deflector 2, completely restricting the movement and rotation of the air deflector 2, and fixing the air deflector 2 on the mounting ring 1.

[0080] (2) Disassembly of the air deflector 2:

[0081] When removing the air deflector 2, the L-shaped handle 304 is pulled in the direction of the middle cross-section of the air deflector 2, driving the locking rod 3 to move along the circumference of the housing 4 until the locking head 302 is completely removed from the locking tapered groove 102, releasing the locking fit. Simultaneously, the air deflector 2 is lifted upward, and the limit block 7, under the action of the second spring 6, exerts an upward lifting force on the air deflector 2, causing the insertion boss 201 to move out of the limit groove 104. The limit fit at the end of the air deflector 2 is released, and the air deflector 2 is completely free of restrictions, completing the rapid removal of the air deflector 2.

[0082] The above description is an explanation of the present invention, not a limitation of the present invention. The scope of the present invention is defined in the claims. Any modifications may be made within the scope of protection of the present invention.
