[0002] With the continuous development of deep-sea marine resources, the demand for research and simulation of the deep-sea marine environment in various laboratories is increasing. As an important experimental facility, deep-water experimental pools play a key role in fields such as marine engineering, resource exploration and ecological research.

[0003] However, most current deep-water laboratories still have certain limitations, mainly in that their experimental designs often focus on single-factor effects, making it difficult to comprehensively simulate complex multi-factor coupled environments. For example, deep-water, shallow-water, and land-based structural experiments have different requirements for environmental conditions such as water depth, pressure, flow velocity, and temperature, and existing floating bottom systems in laboratories are usually unable to flexibly adapt to these diverse experimental needs, thus limiting the accuracy and applicability of experimental results.

Detailed Implementation

[0029] The principles of this disclosure will now be described with reference to several exemplary embodiments illustrated in the accompanying drawings. While preferred embodiments of this disclosure are shown in the drawings, it should be understood that these embodiments are described only to enable those skilled in the art to better understand and implement this disclosure, and are not intended to limit the scope of this disclosure in any way.

[0030] The term “comprising” and its variations as used herein signify open inclusion, i.e., “including but not limited to”. Unless otherwise stated, the term “or” means “and / or”. The term “based on” means “at least partially based on”. The terms “one example embodiment” and “one embodiment” mean “at least one example embodiment”. The term “another embodiment” means “at least one additional embodiment”. The terms “first,” “second,” etc., may refer to different or the same objects. Other explicit and implicit definitions may also be included below.

[0031] like Figure 1-2 As shown, this embodiment provides a water depth adjustment device for a test pool, including a floating body, a lifting mechanism, a clamping device, and a distributed detachable platform;

[0032] The lifting mechanism is configured in multiple sets, each set including a winch, a steering pulley, and a steel wire rope. One end of the steel wire rope is connected to the winch, and the other end passes over the steering pulley located at the bottom of the deep-water experimental pool and connects to the floating body. The floating body rises by buoyancy and is then pulled down by the winch. The lifting speed of the floating body is controlled by the speed of the winch's rope winding and unwinding. In a static state, the levelness of the floating body can be controlled by adjusting the steel wire rope using multiple winches.

[0033] The clamping device includes a cylinder, a connecting shaft, a guide wheel, and a base. The cylinder, located on the base, is connected to the guide wheel via the connecting shaft. The guide wheel engages with guide grooves on both sides of the floating body. Figure 6 As shown, when the floating body adjusts the water depth, the cylinder retracts the piston rod. After the body is raised or lowered to the correct position, the cylinder extends the piston rod, and the guide wheel presses against the guide slide assembly, thus locking the floating body in place. This effectively prevents the floating body from jamming against the pool wall and significantly reduces the risk of movement or rotation of the floating body.

[0034] The distributed, detachable platform is laid on the floating bottom body via connecting brackets. It overcomes the problem that buoyancy alone cannot make the floating bottom flush with the ground, enabling the deep-water experimental pool to conduct civil engineering experiments and wind tunnel experiments. After the experiment is completed, it can be disassembled and reinstalled for use.

[0035] In one example embodiment, the connecting bracket includes a first lightweight cover plate bracket symmetrically arranged along a first short side walkway bracket and a second lightweight cover plate bracket symmetrically arranged along a second short side walkway bracket. A first long side walkway bracket is provided between the first and second lightweight cover plate brackets on one side, and a second long side walkway bracket is provided between the first and second lightweight cover plate brackets on the other side. The inner ends of the first, second, first, and second short side walkway brackets, as well as the first and second long side walkway brackets, are all connected to an annular walkway bracket, and the arc-shaped edge of the annular walkway bracket is connected to the first and second lightweight cover plate brackets. Figure 3As shown, the distributed detachable platform includes multiple polyurethane foam boards, a first short-side walkway board, a second short-side walkway board, a first long-side walkway board, a second long-side walkway board, and a ring-shaped walkway board. The polyurethane foam boards are laid integrally on a first lightweight cover plate support and a second lightweight cover plate support. The first short-side walkway board, the second short-side walkway board, the first long-side walkway board, and the second long-side walkway board are respectively laid on their corresponding first short-side walkway support, second short-side walkway support, first long-side walkway support, and second long-side walkway support. The ring-shaped walkway board is laid on a ring-shaped walkway support. Furthermore, the reinforcing beams of the first short-side walkway support, the second short-side walkway support, the first long-side walkway support, and the second long-side walkway support are located on the box girder of the box structure and fixed with bolts. A portion of the reinforcing beams of the ring-shaped walkway support are located on the box girder of the box structure.

[0036] When assembling the distributed detachable platform, first assemble two long-side walkway supports and two short-side walkway supports. Then install the ring-shaped walkway support and connect it to the long-side and short-side walkway supports. Next, install the first and second lightweight cover plate supports and connect them to each walkway support. After the connecting supports are assembled, lay them on the floating body. Then, lay the first short-side walkway plate, the second short-side walkway plate, the first long-side walkway plate, the second long-side walkway plate, and the ring-shaped walkway plate on the corresponding first short-side walkway support, second short-side walkway support, first long-side walkway support, second long-side walkway support, and ring-shaped walkway support, respectively. Finally, lay polyurethane foam boards on the first and second lightweight cover plate supports to completely cover the floating body.

[0037] The distributed detachable platform is manually installed to make the floating body level with the ground. Experimental equipment is then installed on the rotating worktable for civil engineering or wind tunnel experiments. It is important to note that people are prohibited from walking on the polyurethane foam board or placing heavy objects on it. All related activities should be carried out on the walkway board. After the experiment, the distributed detachable platform should be promptly dismantled and placed in the designated location for use in the next experiment.

[0038] like Figure 4-5 As shown, the rotating worktable is located in the middle of the floating body and is engaged with a guide ring. The rotating worktable is connected to an underwater hydraulic motor and can rotate. Experiments can be simulated using the rotating worktable when the direction of the flow field (wind, waves, current, etc.) forms an angle with the experimental equipment on the worktable. It should be noted that the floating body is not allowed to rise or fall while the rotating worktable is moving. Conversely, the rotating worktable is not allowed to move while the floating body is rising or falling.

[0039] The aforementioned floating device has the ability to conduct experimental simulations of deep water, shallow water, and land structures, which improves work efficiency, reduces labor costs, and better meets the experimental requirements of deep water experimental pool models.

[0040] The above description is merely an optional embodiment of this disclosure and is not intended to limit this disclosure. Various modifications and variations can be made to this disclosure by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.

[0041] Although the claims in this application have been formulated for specific combinations of features, it should be understood that the scope of this disclosure also includes any novel feature or any novel combination of features, whether express or implied or generalized herein, whether or not it relates to the same scheme in any of the claims currently claimed.
