Embodiment Construction

[0019] The present invention will be further described below in conjunction with the drawings. Such as figure 1 As shown,

[0020] One end of the U-shaped elbow pipe 1 is flanged with the straight pipe 6 and bolted, the other end of the U-shaped elbow pipe 1 is fixedly connected with the long tapered pipe 10, and the airfoil guide vane 2 is installed inside the U-shaped elbow. The guide vane 2 is installed densely inside and sparse outside, and the spacing is in a form of geometric array arrangement. The taper of the long tapered pipe 10 is 4°; the straight pipe 6 is equipped with a steel wire mesh 5, which can decompose the vortex of the incoming water flow into small vortices, reduce the impact of the sink, and make the water flow straighter; tapered with curvature The pipe 7 is streamlined, and the two ends are respectively connected by flanges, one end is connected to the straight pipe 6, and the other end is connected to the U-shaped water tank 9. The U-shaped water tank 9...

Abstract

The invention relates to a novel circulation experiment water tank composed of a U-shaped elbow, wing-shaped flow deflectors, a bolt, a flange, steel wire nets, a straight tube, a cambered tapered tube, a minor-diameter straight tube, a U-shaped water tank body and a long tapered tube. The whole water tank is made of organic glass, and is high in transparency and mechanical strength, light and easy to machine. The wing-shaped flow deflectors are small in resistance and good in diversion feature, and the fluid flow speed is effectively controlled. The straight tube and the cambered tapered tube are connected through the bolt and the flange, and are convenient to dismount. The steel wire nets are installed in the straight tube section, a water flow vortex flowing from the U-shaped elbow is divided into small vortexes, the impact to the water tank is reduced, and the water flow tends to be straight. The long tapered tube effectively prevents an inner bounding layer of the long tapered tube from disengaging. The cambered tapered tube is in a streamline shape and effectively prevents a boundary layer from disengaging, the two ends of the cambered tapered tube are connected through the flange, and the cambered tapered tube is convenient to install and easy to replace. The novel circulation experiment water tank is good in adjusting performance, stable in operation, convenient to manufacture, even in internal fluid flowing speed and simple in structure, brings great convenience to the actual application, and can be widely applied to indoor hydraulics experiments.

Description

Technical field [0001] The invention relates to a new type of circulating experimental water tank, in particular to an experimental water tank used in indoor hydraulic experiments, in particular to a circulating water flow experimental water tank used in mechanical experiments, and belongs to the field of experimental equipment. Background technique [0002] With the development of modern science, there are more and more fluids not only in the research of ship engineering resistance, propulsion, maneuvering, and seaworthiness, but also in marine engineering, fishery production, hydrology and hydraulic machinery. Mechanical problems need to be studied and solved. As long as the requirements of similar theories are met, these problems can be tested in wind tunnels, towing pools, water tunnels or circulating water tanks. With the development of science and technology, circulating water tanks are gradually established and perfected all over the world. Compared with the towing pool,...
