Embodiment Construction

[0023] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, but they do not constitute a limitation to the present invention.

[0024] The outlet pool 1 of the present invention is constructed of concrete. The bottom is composed of a rear bottom plate 10 and a front side bottom plate 9 from left to right; a backwater 1-1 is arranged between the right side of the front bottom plate and the experimental water tank 6, and the outlet The pool communicates with the reservoir 2 through the backwater port, and a gate 5 is provided on the backwater port; the front bottom of the outlet pool changes from left to right, from a slope to a horizontal plane flush with the bottom of the experimental water tank; the width of the outlet pool is from the slope part Begins to shrink, and gradually shrinks to the width of the experimental water tank at the end of the slope (from figure 2 Known); the height of the side wall of ...

Abstract

The invention relates to a tidal bore tide head generating device for indoor physical model experiments. The tidal bore tide head generating device aims at simulating high flow-speed strong tidal bore tide heads. According to the technical scheme, the tidal bore tide head generating device for indoor physical model experiments comprises a water outlet pool, an experiment water trough, a water storage pool and a gate opening and closing control device; immersible pumps are installed in the water storage pool, immersible pump water outlet holes are formed in a rear side bottom plate of the water outlet pool, a front side bottom plate and a water return port are arranged between the rear side bottom plate and the bottom of the experiment water trough in sequence, and the water return port is provided with a gate; from the left end of a slope, the width of the water outlet pool is gradually reduced from left to right, and is reduced to be equal to the width of the experiment water trough at the right end of the slope; the height of the part, on the front side bottom plate, of the pool wall of the water outlet pool is larger than the height of the completely-open gate, and a safe distance is reserved; at least two layers of energy dissipating plates are arranged between the left side of the water outlet pool and the water storage pool, wherein the energy dissipating plates located on the top layer are arranged below the slope of the front side bottom plate, and the rest of the energy dissipating plates are arranged at equal intervals.

Description

Technical field [0001] The invention belongs to the field of estuarine and coastal physical model experiments, and specifically relates to a tidal head generating device for indoor physical model experiments. Background technique [0002] Tide bore is a phenomenon of rapid tidal surge in the estuary of rivers entering the sea, and local deformation is severe during the propagation process, which has a significant impact on river erosion, embankment protection and water engineering. In order to conduct scientific research on the flow structure, turbulence characteristics, and the impact of tidal bore on sediment, salinity and pollutant transport, and solve practical problems in production, physical model experiments can be used to simulate the law of tidal bore movement. Therefore, there is a need for a tidal head generating device involving indoor physical model experiments. [0003] At present, there is no effective method for indoor physical model experiments to quickly, easily ...
