Description

Technical Field

[0001] This invention relates to the field of underwater unmanned vehicle technology, specifically to an underwater multi-layer load loading and release device. Background Technology

[0002] When loading, transferring, and deploying multi-layer underwater payloads on underwater unmanned vehicles, as well as when operating for extended periods in marine environments, existing loading and release devices have some shortcomings. They are prone to malfunctions or failures at critical moments, cannot meet high precision requirements, and are difficult to operate and maintain. They are also complicated, inefficient, and inconvenient to use. Summary of the Invention

[0003] In view of this, the present invention provides an underwater multi-layer load loading and release device that simplifies the loading process, improves loading efficiency, and ensures reliable loading and release.

[0004] The technical solution adopted in this invention is as follows:

[0005] An underwater multi-layer load loading and release device includes a locking and release mechanism and a loading mechanism;

[0006] The locking and releasing mechanism is a frame structure. The loading mechanism is arranged at intervals on the locking and releasing mechanism in the vertical direction and locked with the locking and releasing mechanism to support and position the upper and lower underwater loads.

[0007] Furthermore, the locking and releasing mechanism includes a mounting bracket and a drive mechanism;

[0008] The mounting bracket is used to install on an underwater transport platform; the loading and releasing of underwater loads are achieved through the action of the drive mechanism.

[0009] Furthermore, the mounting frame has a symmetrical structure, including a fixing frame, a connecting beam, and a driving mounting beam;

[0010] The fixing frame is arched and located on both sides. The connecting beam and the drive mounting beam are fixed between the fixing frame, with each beam positioned on one side. The connecting beam is used to install the loading mechanism, and the drive mounting beam is used to install the drive mechanism.

[0011] Furthermore, the drive mechanism includes a drive source, a screw, and a locking / releasing hook;

[0012] The drive source is used to drive the screw to rotate. The screw is a round rod structure with reverse threads at both ends. The locking and releasing hook includes two L-shaped blocks. The two L-shaped blocks are respectively engaged with the threads at both ends of the screw for fixing and releasing the loading mechanism. When the two L-shaped blocks are closed, they form a U-shaped structure.

[0013] Furthermore, the loading mechanism includes a locking screw, a rotating rod, a contour seat, a connecting frame, and a locking block;

[0014] The connecting frame is a U-shaped frame, with its opening rotatably connected to the rotating rod. Locking screws are provided at both ends of the rotating rod, which are used to fix the loading mechanism to the connecting beam. The connecting frame has contour seats on both sides, which are symmetrical structures for positioning the upper and lower underwater loads. The locking block is fixed to the bottom of the connecting frame and has a through hole for cooperating with the screw to fix it to the drive mounting beam. When locked, it is located in the U-shaped structure.

[0015] Furthermore, the inner wall of the horizontal portion of the L-shaped block is inclined, thus forming a concave structure with a lower middle and higher sides at the bottom; the locking block is a wedge-shaped block, and in the locked state, the bottom surface of the wedge-shaped block matches the shape of the bottom surface inside the concave structure.

[0016] Furthermore, the drive mounting beam is provided with two lower support ears, which are used to cooperate with the screw to limit the two L-shaped blocks between the two lower support ears.

[0017] Beneficial effects:

[0018] 1. This invention achieves the support and positioning of upper and lower underwater loads through the cooperation of locking and releasing mechanism and loading mechanism, which can meet the loading and releasing requirements of multi-layer loads and the loading and releasing is reliable.

[0019] 2. Except for the drive source, the present invention is a purely mechanical transmission device, which has high reliability, good environmental adaptability, and can meet the requirements of various environments.

[0020] 3. The present invention is achieved by rotating the connecting frame and the rotating rod. When loading, the connecting frame is locked with the locking and releasing mechanism. When released, the connecting frame flips downward under the combined force of its own weight and the upper load, and the loading mechanism opens to complete the load delivery. This simplifies the loading process and improves loading efficiency.

[0021] 4. The present invention achieves locking through the cooperation between the locking block, the lower support lug, and the screw, which has low requirements for loading and fitting accuracy, and the assembly process is simple and easy to implement. Attached Figure Description

Detailed Implementation

[0029] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] The present invention provides an underwater multi-layer load loading and release device, including a locking and release mechanism 1 and a loading mechanism 2; the locking and release mechanism 1 is a frame structure, and the loading mechanism 2 is arranged at intervals on the locking and release mechanism 1 in the vertical direction and locked with the locking and release mechanism 1 to support and position the upper and lower underwater loads.

[0031] It can be set to a specified number of layers according to actual requirements, such as Figure 1 , Figure 2 As shown, in this embodiment, the underwater multi-layer load loading and release device has a two-layer structure. The loading mechanism 2 consists of two parts, which are arranged vertically and horizontally on the locking and release mechanism 1.

[0032] like Figure 3 As shown, the locking and releasing mechanism 1 includes a mounting frame 3 and a drive mechanism 4; the mounting frame 3 is used to install on an underwater transport platform; the loading and releasing of underwater loads is achieved through the action of the drive mechanism 4.

[0033] like Figure 5 As shown, the mounting frame 3 has a symmetrical structure, including a fixed frame 10, a connecting beam 11, and a drive mounting beam 12. The fixed frame 10 is arched, with its inner wall matching the shape of the underwater load. The fixed frame 10 is positioned on both sides, with the connecting beam 11 and the drive mounting beam 12 fixed between the fixed frame 10, each positioned on one side and located in the middle of the fixed frame 10. The connecting beam 11 is used to install the loading mechanism 2, and the drive mounting beam 12 is used to install the drive mechanism 4. The drive mounting beam 12 has two lower lugs, which are used to engage with the screw 14 of the drive mechanism 4 to limit the locking release hook 15 between the two lower lugs.

[0034] like Figure 6As shown, the drive mechanism 4 includes a drive source 13, a screw 14, and a locking and releasing hook 15. The drive source 13 is fixed to the bottom surface of the drive mounting beam 12 and is used to drive the screw 14 to rotate; it can be a motor. The screw 14 is a round rod structure with reverse threads at both ends. The locking and releasing hook 15 includes two L-shaped blocks, which respectively engage with the threads at both ends of the screw to fix and release the loading mechanism 2. When the two L-shaped blocks are closed, they form a U-shaped structure.

[0035] like Figure 4 As shown, the loading mechanism 2 includes a locking screw 5, a rotating rod 6, a contour seat 7, a connecting frame 8, and a locking block 9. The connecting frame 8 is a U-shaped frame, with its opening rotatably connected to the rotating rod 6. The rotating rod 6 is a cylindrical structure used for the connecting frame 8 to rotate around it. Locking screws 5 are provided at both ends of the rotating rod 6, which are used to fix the loading mechanism 2 to the connecting beam 11. Contouring seats 7 are provided on both sides of the connecting frame 8. The contour seats 7 are symmetrical structures used for positioning the upper and lower underwater loads. The upper surface is a concave arc surface, and the lower surface is a convex arc surface, matching the shape of the underwater load. The locking block 9 is fixed to the bottom of the connecting frame 8 and has a through hole for cooperating with the screw 14 to fix it to the drive mounting beam 12. When locked, it is located in the concave structure.

[0036] Preferably, the inner wall of the horizontal part of the L-shaped block of the locking release hook 15 is inclined, and the bottom surface of the concave structure formed by this is low in the middle and high on both sides, forming a large V-shape with a large included angle; the locking block 9 is a wedge-shaped block, and the bottom surface of the wedge-shaped block matches the shape of the bottom surface of the concave structure in the locked state, so as to ensure that the locking block 9 is located in the middle of the concave structure, which is convenient for centering.

[0037] The loading process for this device is as follows:

[0038] 1) Use locking screws 5 to fix the loading mechanism 2 to the connecting beam 11, keeping the loading mechanism 2 in a naturally drooping state;

[0039] 2) Lift the underwater load to the uppermost part of the inner side of the fixed frame 10;

[0040] 3) Drive source 13 rotates, and adjusting screw 14 moves locking release hook 15 to the release position, that is, the two L-shaped blocks are in the open and separated state;

[0041] 4) Rotate the connecting frame 8 of the loading mechanism 2 along the rotating rod 6 until the wedge block is hooked into the two lower support ears of the drive mounting beam 12 and is located between the two L-shaped blocks;

[0042] 5) Drive source 13 rotates, adjust screw 14 to place locking release hook 15 in storage position, that is, the two L-shaped blocks are joined and closed to form a U-shaped structure, and the loading of the upper underwater load is completed.

[0043] 6) Lift the lower underwater load onto the lower part of the upper contour seat 7 and repeat steps 3) to 5) to complete the loading of the lower underwater load.

[0044] The release process of this device is as follows:

[0045] 1) Drive source 13 rotates, and adjusting screw 14 moves locking release hook 15 to the storage position;

[0046] 2) Under the combined force of the underwater load and the loading mechanism 2, the rotating rod 6 and the connecting frame 8 generate a downward overturning torque, and the loading mechanism 2 opens to complete the underwater load delivery.

[0047] In summary, the above are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
