Abstract

The invention relates to a 1/4 elliptic cone conical table eddy eliminating device and method for a closed intake pool. The device comprises a closed intake pool, and a water pump and a horn pipe mouth mounted in the closed intake pool, wherein a water guide cone is arranged on a baseplate of the intake pool right below the horn pipe mouth. The device is characterized in that the water guide cone is a 1/4 elliptic cone conical table; the distance from the 1/4 elliptic cone conical table to the back wall of the closed intake pool is equal to the diameter of the horn pipe mouth; the height of the 1/4 elliptic cone conical table is 2/5 of the diameter of the horn pipe mouth of the water pump; the cone bottom diameter of the 1/4 elliptic cone conical table is equal to the diameter of the horn pipe mouth of the water pump; the cone top diameter of the 1/4 elliptic cone conical table is 7/25 of the diameter of the horn pipe mouth of the water pump; and the elliptic cone section of the 1/4 elliptic cone conical table is 1/4 of an elliptic cone. The device is reasonable and simple in structure, easy in manufacturing and convenient to use, and enables the section flowing speed of water currents entering the water pump and the pipe to become uniform by rectifying currents and adjusting the pool bottom speed.

Description

technical field [0001] The invention relates to a vortex elimination device, in particular to a 1 / 4 ellipse conical table vortex elimination device for a closed water inlet pool and a method thereof, belonging to the technical field of design of a closed water inlet pool. Background technique [0002] There are many research results on open intake tanks at home and abroad. On this basis, the research on box culvert intake channels has become the mainstream of research in recent years, but there are few studies on closed intake tanks. [0003] Due to the arrangement of the suction pipe in the water pump inlet pool, the internal flow state of the water inlet pool and the water suction pipe is extremely complicated. Two kinds of vortices, the water surface vortex and the attached bottom vortex, often appear in the water inlet pool, which are important factors affecting the stable operation of the pump device. Among them, the water surface vortex that often appears in the open w...
