Omnidirectional flow making pipeline system of underwater vibrating platform

Abstract

An omnidirectional flow making pipeline system of an underwater vibrating platform relates to the technical field of simulating testing of vibrating platforms in areas such as civil engineering and water conservancy and a flow field. A streamline type structure is utilized and controlling by a shutter and glow guiding blades and the like realizes omnidirectional flow making of a testing pool. Secondly, an L-shaped converge area can flowing-out and returning of a water flow in a transverse direction, and can ensure flowing-out and returning of the water flow in a longitudinal direction. Thirdly, the flow guiding blades and the baffle plate can effectively realize testing area dividing and water flow direction control in the testing area. Under a precondition of flow making in different directions, high-efficiency pool utilization is realized. Finally, a bidirectional through-flow pump is utilized and is configured at the lower layer of a flow making pool. A whole flow length of outgoingwater and effective flow controlling can be ensured, and a requirement for omnidirectional flow making is satisfied. Through cooperation of the functions and the underwater vibrating platform (platform array), an earthquake-water power coupling testing of an ultra-large and ultra-long structure can be realized, and furthermore quick and high-efficiency loading of different water flow directions is ensured.

Description

technical field [0001] The invention relates to the technical field of vibration table and flow field simulation tests of civil engineering, water conservancy, etc., and is a pipeline system capable of realizing flow generation in all directions. Background technique [0002] With the continuous construction of offshore and coastal structures and sea-crossing bridges, and the continuous occurrence of damage to wading projects during earthquakes, the engineering and scientific communities have gradually paid attention to the coupled excitation mechanism of hydrodynamics and earthquakes and the seismic response of structures. . In the future, the development trend of the vibrating table will gradually develop from no water to water, and gradually from static water to dynamic water. [0003] In hydrodynamics, the role of flow (including rivers and ocean currents) cannot be ignored, especially for structures with large water depths (such as deep-water docks, offshore wind power...

Problems solved by technology

However, for the shaking table (array) test with a large model scale, especially for structures such as long-span bridges, underwater tunnels, and port terminals, the structural building volume is large, and the scale differences in different directions are large. The effect of the flow in different directions on the fluid-solid coupling characteristics and seismic response of the structure is quite different, and it is very difficult to simulate the flow in different directions by adjusting the direction of the model during the test
