However, most of the current deep-water laboratories still have the limitation of focusing on the role of single factors. However, the experimental conditions and experimental standards required for simulation experiments of different environmental factors are different. The existing floating bottom in the laboratory is difficult to have the ability to simulate deep water, shallow water and land structures at the same time. Summary of the invention

[0027] The principles of the present disclosure will be described below with reference to several example embodiments shown in the accompanying drawings. Although preferred embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that these embodiments are described only to enable those skilled in the art to better understand and implement the present disclosure, and are not intended to limit the scope of the present disclosure in any way.

[0028] As used herein, the term "including" and its variations mean open inclusion, i.e., "including but not limited to". Unless otherwise stated, the term "or" means "and / or". The term "based on" means "based at least in part on". The terms "an example embodiment" and "an 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.

[0029] like Figure 1-2 As shown, this embodiment provides a liftable floating bottom structure device suitable for deep-water experiments, including a floating bottom body, a lifting mechanism, a tightening device and a distributed detachable platform;

[0030] The lifting mechanism is provided with multiple groups, each group includes a winch, a steering pulley, and a wire rope. One end of the wire rope is connected to the winch, and the other end is connected to the floating bottom body by passing through the steering pulley located at the bottom of the deep-water experimental pool. The floating bottom body rises by buoyancy, and then is pulled down by the pulling force of the winch. The lifting speed of the floating bottom body is controlled by the speed of the winch to retract and release the rope. In a static state, the horizontality of the floating bottom body can be controlled by adjusting the wire rope through multiple winches.

[0031] The tightening device includes a cylinder, a connecting shaft, a guide wheel and a base. The cylinder on the base is connected to the guide wheel through the connecting shaft. The guide wheel is clamped with the guide grooves on both sides of the floating bottom body. Figure 6 As shown in the figure, when the floating bottom body adjusts the water depth, the cylinder retracts the piston rod, and after it is lifted and lowered to the right position, the cylinder extends the piston rod, and the guide wheel presses against the guide slide assembly to achieve the positioning and locking of the floating bottom. This effectively prevents the floating bottom body from getting stuck with the pool wall, and better avoids the movement and rotation of the floating bottom body.

[0032] The distributed detachable platform is laid on the floating bottom body through the connection bracket. It overcomes the problem that the floating bottom cannot be flush with the ground by relying solely on buoyancy, and realizes the function of conducting civil engineering experiments and wind tunnel experiments in the deep water test pool. After the experiment is completed, it can be disassembled and reinstalled for use;

[0033] In an exemplary embodiment, the connecting bracket includes a first light-weight cover bracket symmetrically arranged along the first short-side walkway bracket, and a second light-weight cover bracket symmetrically arranged along the second short-side walkway bracket. A first long-side walkway bracket is arranged between the first light-weight cover bracket and the second light-weight cover bracket on one side, and a second long-side walkway bracket is arranged between the first light-weight cover bracket and the second light-weight cover bracket on the other side. The inner ends of the first short-side walkway bracket, the second short-side walkway bracket, the first long-side walkway bracket, and the second long-side walkway bracket are all connected to the annular walkway bracket, and the arcuate edges of the annular walkway bracket are connected to the first light-weight cover bracket and the second light-weight cover bracket. Figure 3 As shown, the distributed detachable platform includes a plurality of 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 circular walkway board, the polyurethane foam boards are respectively laid on the first light cover support and the second light cover 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 the corresponding first short side walkway support, the second short side walkway support, the first long side walkway support and the second long side walkway support, and the circular walkway board is laid on the circular walkway support. Furthermore, the ribs 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 beam of the box structure and are fixed by bolts, and part of the ribs of the circular walkway support are located on the box beam of the box structure.

[0034] When assembling the distributed detachable platform, first assemble two long side walkway brackets and two short side walkway brackets, then install the circular walkway bracket and connect it with the long side walkway bracket and the short side walkway bracket, then install the first lightweight cover bracket and the second lightweight cover bracket and connect them with each walkway bracket, and after the connection brackets are assembled, they are laid on the floating bottom body; then the first short side walkway board, the second short side walkway board, the first long side walkway board, the second long side walkway board, and the circular walkway board are laid on the corresponding first short side walkway bracket, the second short side walkway bracket, the first long side walkway bracket, the second long side walkway bracket, and the circular walkway bracket respectively; and the polyurethane foam board is laid on the first lightweight cover bracket and the second lightweight cover bracket to completely cover the floating bottom body.

[0035] The distributed detachable platform is installed manually, through which the floating bottom body is made flush with the ground, and the experimental equipment is installed on the rotating workbench to carry out civil engineering experiments or wind tunnel experiments. It should be noted that people are prohibited from walking and placing heavy objects on the polyurethane foam board. Related activities should be carried out on the walkway board. After the experiment, the distributed detachable platform should be removed in time and placed in the designated location for use in the next experiment.

[0036] like Figure 4-5 As shown, the rotating workbench is located in the middle of the floating bottom body and is clamped by a guide ring. The rotating workbench is connected to the underwater hydraulic motor and can rotate. When the flow field direction of wind, wave and current is at an angle with the experimental equipment on the workbench, the experimental simulation can be carried out through the rotating workbench. It should be noted that when the rotating workbench is in motion, the floating bottom body is not allowed to be raised or lowered. When the floating bottom body is in a lifting or lowering motion, the rotating workbench is not allowed to be in motion.

[0037] The above-mentioned floating bottom device has the ability to conduct experimental simulations on deep water, shallow water and onshore structures, which improves work efficiency, reduces labor costs, and better meets the requirements of deep water experimental pool model experiments.

[0038] The above description is only an optional embodiment of the present disclosure and is not intended to limit the present disclosure. For those skilled in the art, the present disclosure may have various modifications and variations.
