Description

Technical Field

[0001] This utility model relates to the field of sightseeing submarines, specifically to a buoyancy block quick adjustment mechanism. Background Technology

[0002] In existing technologies, the buoyancy distribution of sightseeing submarines is typically achieved through fixedly arranged buoyancy blocks or by adjusting ballast tanks. However, using fixedly arranged buoyancy blocks, whose positions cannot be changed, makes it impossible to flexibly adjust the buoyancy distribution according to changes in navigation conditions, resulting in poor stability of the hull during turning, acceleration, or load changes. On the other hand, while adjusting the buoyancy distribution using ballast tanks can alter the buoyancy distribution to some extent, this method is slow and requires complex piping systems and pump equipment, resulting in a complex structure and high maintenance costs, which is not conducive to the use of small sightseeing submarines. Therefore, existing buoyancy adjustment technologies are insufficient in terms of structural simplicity, adjustment speed, and applicability. Utility Model Content

Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0037] Furthermore, the term "and / or" in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0038] like Figures 1 to 9 As shown, the buoyancy block quick adjustment mechanism includes a hull 1, a chamber 2, and a first movable module 3. The chamber 2 is located inside the hull 1 and below the passenger cabin of the hull 1. An inspection port is provided at the hull part corresponding to the passenger cabin so that the operator can maintain and operate the first movable module 3 and related structures inside the chamber 2.

[0039] The first moving module 3 is located in the chamber 2 and is used to drive the position adjustment of the buoyancy blocks 4. The buoyancy blocks 4 are divided into two groups. The first moving module 3 can drive the two groups of buoyancy blocks 4 to move synchronously, so that the two groups of buoyancy blocks 4 move closer to each other in the middle of the hull 1, or separate towards the bow and stern of the hull 1, so as to achieve rapid adjustment of the buoyancy distribution of the hull.

[0040] Furthermore, the first moving module 3 includes a motor 301, a gear 302, two racks 303, and two sliding sleeves 304. The motor 301 is fixedly installed inside the chamber 2, and its output shaft is fixedly connected to the gear 302. The gear 302 simultaneously meshes with both racks 303. Each rack 303 is connected to a corresponding sliding sleeve 304 and can reciprocate linearly along a guide structure within the chamber 2. The sliding sleeves 304 are fixedly connected to the buoyancy blocks 4, so that when the motor 301 drives the gear 302 to rotate, it drives the two racks 303 to move relative to each other, thereby pushing the two sets of buoyancy blocks 4 to move synchronously closer or further apart along the length of the hull 1.

[0041] In practical use, when it is necessary to adjust the buoyancy distribution of the hull, the operator can control the forward and reverse rotation of motor 301 to quickly bring the two sets of buoyancy blocks 4 together or separate them. Through this mechanism, the adjustment of the ship's center of gravity and buoyancy distribution can be completed in a short time, thereby improving the balance and stability of the hull in different waters or under different navigation conditions.

[0042] Based on the above-described embodiments, this embodiment further includes two second moving modules 5, the driving directions of which are parallel to the driving direction of the first moving module 3. Through the cooperation of the first moving module 3 and the second moving modules 5, dual driving and precise position control of the buoyancy block 4 within the hull 1 can be achieved, thereby improving the flexibility and stability of buoyancy adjustment.

[0043] Specifically, the second moving module 5 includes a connecting plate 501, an electric push rod 502, and a bracket 503. The connecting plate 501 is fixedly connected to the buoyancy block 4, connecting the buoyancy block 4 to the transmission structure of the second moving module 5. The output end of the electric push rod 502 is fixedly connected to the connecting plate 501, enabling it to drive the buoyancy block 4 to move linearly during extension and retraction. One end of the bracket 503 is fixedly connected to the electric push rod 502, and the other end is mounted on a rack 303, allowing the second moving module 5 to maintain stable support and guidance as the rack 303 moves linearly.

[0044] In practical use, when fine-tuning of the buoyancy block 4 is required, the electric push rod 502 can independently drive the movement of the buoyancy block 4. Thus, while the first moving module 3 provides overall synchronous adjustment, the second moving module 5 can further achieve fine-tuning of the buoyancy block 4. This dual adjustment method effectively ensures the speed and accuracy of buoyancy distribution adjustment, meeting the buoyancy control requirements of different water environments and navigation conditions.

[0045] Based on the above embodiments, this embodiment also includes a third moving module 6. The third moving module 6 is used to drive the buoyancy block 4 to move in a direction perpendicular to the driving direction of the first moving module 3, so as to realize the two-dimensional position adjustment of the buoyancy block 4, thereby further improving the flexibility of buoyancy distribution control.

[0046] Specifically, the third moving module 6 includes two slides 608, two rods 607, and a top plate 609. The two slides 608 are machined on the connecting plate 501, and the two rods 607 are slidably connected to their respective slides 608. The other end of each rod 607 is fixedly connected to the top plate 609. The top plate 609 is connected to an external driving device. When the external driving device is working, it can drive the rods 607 to move along the slides 608, thereby causing the buoyancy block 4 to achieve vertical displacement.

[0047] In a preferred embodiment, the top plate 609 is manually driven. To ensure reliable locking of the position adjustment, the third moving module 6 also includes a limiting plate 601, a handle 604, multiple insertion holes 602, a snap-fit ​​component 603, a frame 605, and a torsion spring 606. Wherein:

[0048] The handle 604 is fixedly connected to the limiting plate 601 to facilitate operation by the operator;

[0049] The limiting plate 601 is fixedly connected to the top plate 609 and the frame 605 respectively, and is used to support and limit the snap-fit ​​structure.

[0050] Multiple insertion holes 602 are machined on the connecting plate 501 and arranged sequentially along the moving direction of the buoyancy block 4;

[0051] One end of the snap-fit ​​603 can pass through the limiting plate 601 and be inserted into any of the sockets 602 to achieve position locking. The snap-fit ​​603 is rotatably connected to the frame 605 via a rotating shaft.

[0052] A torsion spring 606 is provided on the rotating shaft of the snap-fit ​​603, with its two ends connected to the frame 605 and the snap-fit ​​603 respectively, to provide the reset force of the snap-fit ​​603.

[0053] In actual use, the operator can drive the limiting plate 601 through the handle 604, causing the locking piece 603 to disengage from the insertion hole 602. At this time, the top plate 609 can be pushed to drive the rod 607 to slide in the slide groove 608, thereby adjusting the position of the buoyancy block 4. When the buoyancy block 4 is adjusted to the target position, the handle 604 is released, and the locking piece 603 automatically resets under the action of the torsion spring 606 and engages with the corresponding insertion hole 602, thereby reliably locking the position of the buoyancy block 4 and ensuring the stability of the buoyancy distribution.

[0054] The specific embodiments described above do not constitute a limitation on the scope of protection of this utility model. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
