Embodiment Construction

[0028] Below in conjunction with accompanying drawing and specific embodiment the present invention will be described in further detail:

[0029] The continuously adjustable stilling pool shown in the figure includes a pool body with side walls 9 arranged on both sides, one end enters the water and the other end exits the pool body. The steep slope section 1 with adjustable slope is arranged in the pool body along the direction of water flow. The height and length can be adjusted. Adjustable apron 2, height-adjustable stilling barrier 3, length-adjustable seaman 4.

[0030] The specific structure is that a support member 5 is provided at the water inlet and outlet of the stilling pool, and a horizontally movable moving member 6 is arranged on the supporting member 5, and the apron 2 is connected with the horizontally moving member 6 through the apron connecting rod 2.1 for force reduction. The sill 3 is connected to the horizontal movement member 6 through the stilling sill co...

Abstract

The invention discloses a continuously adjustable stilling basin. The continuously adjustable stilling basin comprises a basin body, wherein side walls are arranged on two sides of the basin body and the water inlet is formed in one end of the basin body and a water outlet is formed in the other end of the basin body, and a steep slope section of which the slope can be adjusted, an apron of which the height and length can be adjusted and a riprap of which the length can be adjusted are in sequence arranged in the basin body along the water flow direction. The adjustable underflow stilling basin disclosed by the invention has simple principles, convenience in adjustment and capability of quickly and accurately finding the optimum size of the stilling basin, thereby being capable of saving the occupied time for modifying a model while a model test is carried out, and the adjustable underflow stilling basin is further applied to the model test of hydraulic structures, especially suitable for solving the problem of underflow energy dissipation to provide preconditions for shortening the design cycle of a water conservancy project.

Description

technical field [0001] The invention relates to a hydraulic model test device, in particular to an adjustable stilling pool for bottom flow energy dissipation. [0002] technical background [0003] Energy dissipation and anti-scouring is an important issue in the design of drainage structures in hydraulic projects, and it is directly related to the safety and economy of the project. There are three types of energy dissipation and anti-scour methods commonly used in engineering: bottom flow, surface flow and deflected flow. Different types of energy dissipation methods are suitable for different engineering conditions, such as hydrology, geology, topography, construction and operation management, etc. [0004] Bottom flow energy dissipation is a relatively mature energy dissipation method, and its main energy dissipation works are stilling basins, which are widely used in plain sluices. When the high-speed jet enters the stilling pool along the bottom of the sluice, it is su...
