Description

Technical Field

[0001] This utility model relates to the field of deep-sea experimental pool technology, specifically to a movable and detachable false bottom for a deep-sea experimental pool. Background Technology

[0002] As research into marine engineering continues to deepen, the construction of marine engineering laboratories is also increasing. The research, design and testing of deep-sea engineering cannot be separated from deep-water test pools, which can mainly simulate the effects of wind, waves, currents and water depth on structures in the ocean.

[0003] Currently, the false bottoms of water tanks in various laboratories are usually supported by buoyancy and pulled downward by steel cables to achieve floating and stopping, thus forming different water tank depths for testing or equipment installation. However, the water surface in the tank is usually still a certain distance from the upper edge of the tank. Therefore, relying solely on the buoyancy of the false bottom cannot float to the horizontal ground, which cannot meet the needs of the wind and wave joint laboratory to carry out wind tunnel tests for civil engineering. Utility Model Content

[0004] The purpose of this invention is to provide a movable and detachable false bottom for a deep-sea experimental pool. This device can make the upper surface of the false bottom basically flush with the ground, thereby meeting the requirements of wind tunnel testing in civil engineering.

[0010] As a preferred embodiment, the first short-side walkway slab, the second short-side walkway slab, the first long-side walkway slab, and the second long-side walkway slab 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 annular walkway slab is laid on the annular walkway support.

[0011] As a preferred option, the polyurethane foam board connected to the circular walkway panel has an arc-shaped clearance at its end.

[0012] As a preferred embodiment, the false bottom body is a box-type structure, which is symmetrical about the longitudinal centerline and the transverse centerline, and is made by welding longitudinal and transverse box beams.

[0013] As a preferred embodiment, the annular walkway is equipped with a circular workbench for placing testing equipment for testing.

[0015] As a preferred option, when the upper surface of the dummy bottom is flush with the ground, the dummy bottom body is first fully floated and fixed when it rises to the surface. Then, the connecting bracket is installed on the dummy bottom body, and finally, the distributed detachable platform is laid on the connecting bracket, at which point the upper surface of the distributed detachable platform is flush with the ground.

[0016] This utility model, by adopting the above technical solution, achieves the following technical effects: This dummy bottom can not only perform marine engineering tests, but also civil engineering tests and wind tunnel tests; its structure is safe and reliable, and its operation is convenient. Each polyurethane foam board is coded and marked to ensure correct and efficient subsequent installation, and to reproduce the initial installation state. Attached Figure Description
