Description

Technical Field

[0001] The present invention relates to the technical field of deep - water experimental pools, and particularly to an automatically rotating working platform installed on a floating bottom. Background Art

[0002] With the continuous increase in the research on ocean engineering, the construction of deep - water laboratories for ocean engineering is also increasing. The deep - water experimental pool is an important part of the deep - water laboratory for deep - sea engineering. The research, design, and production of deep - sea engineering are inseparable from the deep - water experimental pool, and the relevant technical information and data all come from the test results of the deep - water experimental pool.

[0003] The floating bottom is an important device in the deep - water experimental pool. The platform for placing the experimental model is on its upper part, and different experimental water depths can be simulated by controlling the lifting of the floating bottom. Currently, all the floating bottoms of laboratory pools do not have the function of automatically rotating the model underwater. When it is necessary to simulate different incoming flow directions, the floating bottom can only be lifted out of the water surface, and then the model is manually rotated, and then lowered to the corresponding water depth. This results in a relatively complex experimental process and a relatively long experimental time. Summary of the Invention

[0004] The purpose of the present invention is to provide an automatically rotating working platform installed on a floating bottom, which has a simple structure, is convenient for maintenance, and can make the experimental model rotate automatically underwater, thereby changing the incoming flow direction.

[0005] To achieve the above - mentioned purpose, the technical solution of the present application is: an automatically rotating working platform installed on a floating bottom, including a rotating working platform main body, a first guide ring, a second guide ring, an underwater hydraulic motor, rolling wheels, sliding bearings, and rolling wheel shafts; the first guide ring is connected to the second guide ring, and the rotating working platform main body is arranged inside both of them. A plurality of rolling wheel shafts are connected to the outer periphery of the rotating working platform main body. Each rolling wheel shaft is connected with a rolling wheel through a sliding bearing, and the rolling wheels are located between the first guide ring and the second guide ring; the bottom of the rotating working platform main body is connected to the underwater hydraulic motor.

[0006] Further, a convex - platform structure extending upward is arranged on the outer periphery of the second guide ring, and this convex - platform structure is connected to the first guide ring through bolts.

[0007] Further, a cavity for accommodating the rolling wheels is formed after the first guide ring and the second guide ring are connected.

[0008] Further, a plurality of lifting eye bolts are distributed on the rotating working platform main body, and each lifting eye bolt is connected to the experimental model through a rope to fix the model.

[0009] Further, the second guide ring is fixed on the floating bottom through bolts.

[0010] Further, the second guiding ring is fixed in the middle of the floating bottom.

[0011] Further, the central part of the rotating working platform body is of a cavity structure.

[0012] Further, the underwater hydraulic motor is connected to the bottom of the rotating working platform body by bolts.

[0013] Due to the adoption of the above technical solutions, the present invention can achieve the following technical effects: 1) The present invention can realize the automatic rotation of the experimental model underwater. 2) The structure of the present invention is simple and detachable. When the rotating working platform fails, the rotating working platform can be directly detached from the floating bottom for maintenance. 3) The central part of the rotating working platform body of the present invention is a cavity. When underwater, the force transmitted to the floating bottom due to its own buoyancy is small. 4) The present invention can fix the model through the lifting eye screws.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The principles of the present disclosure will now be described with reference to several exemplary embodiments shown in the drawings. Although the preferred embodiments of the present disclosure are shown in the drawings, it should be understood that the description of these embodiments is only for enabling those skilled in the art to better understand and then implement the present disclosure, rather than limiting the scope of the present disclosure in any way.

[0019] As used herein, the term "including" and its variants mean 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 "an exemplary embodiment" and "an embodiment" mean "at least one exemplary embodiment". The term "another embodiment" means "at least one additional embodiment". The terms "first", "second", etc. may refer to different or the same objects. There may be other explicit and implicit definitions hereinafter.

[0020] This embodiment provides an automatically rotating working platform installed on a floating bottom, which includes a rotating working platform main body, a first guide ring, a second guide ring, an underwater hydraulic motor, rolling wheels, sliding bearings, rolling wheel shafts, and lifting eye bolts; the underwater hydraulic motor drives the rotation of the rotating working platform main body; one end of a rope is connected to the experimental model, and the other end is connected to the lifting eye bolt to fix the experimental model. Since the experimental model is fixed on the rotating working platform main body, when the rotating working platform main body rotates, it will also drive the experimental model to rotate, achieving the purpose of changing the oncoming flow direction.

[0021] As Figure 1 shown, the automatically rotating working platform is installed at the central position of the floating bottom 3. The rotating working platform main body 2 can be used for fixing the experimental model and realizing the rotation of the model. Its upper part is a stainless steel plate, which can protect the working platform from being bumped by the model. There is a 360° scale on the first guide ring 3.

[0022] As Figure 2 shown, multiple lifting eye bolts 6 are evenly distributed on the rotating working platform main body 2 for fixing the experimental model. The underwater hydraulic motor 5 is located at the bottom of the rotating working platform main body 2, and the underwater hydraulic motor 5 can be controlled by a PLC controller to provide power for the rotation of the working platform.

[0023] As Figure 3 shown, a plurality of rolling wheels 7 are evenly installed around the rotating working platform main body 2. The rolling wheels are located between the first guide ring and the second guide ring. The rolling wheels 7 are installed on the rolling wheel shafts 9 through sliding bearings 8, and the rolling wheel shafts are fixed on the outer circumference of the rotating working platform main body 2. The sliding bearings can adopt engineering plastic alloy KGB sliders. This material has a small frictional resistance and can rely on water lubrication without the need to refuel underwater, which is suitable for underwater working conditions. The first guide ring 3 is connected to the second guide ring 4 by bolts, and the second guide ring 4 is connected to the floating bottom 1 by bolts.
