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
The present invention relates to a kind of Novel circulation experiment water tank, particularly a kind of in the experimental trough of indoor water Experiments of Machanics, be specifically related to, with the circulating water flow experimental trough with Experiments of Machanics, belong to field of experiment equipment.
Background technology
Along with the development of modern science, at present not only in the relevant researchs such as the resistance of Marine engineering, propelling, manipulation and sea keeping quality, and in oceanographic engineering, fish production, the hydrology and hydraulic etc., have more and more many fluid mechanics problems need research and solve.As long as meet the requirement of similarity theory, these problems can be tested in wind-tunnel, towing basin, water hole or circulating water chennel.Along with the development of science and technology, circulating water chennel is progressively set up all over the world and is gradually improved.It compares with towing basin, the advantage having convenient test and not do not replaced by time restriction etc., therefore becomes the important tests equipment of the researchs such as boats and ships in modern age, oceanographic engineering, aouatic structure and fluid motion.Existing circulating water chennel, difficulty of processing is large, and complex structure, cost is high.Therefore, development of new circulating water chennel seems particularly important.
The present invention is exactly the deficiency that will overcome existing circulating water chennel, provides a kind of Novel circulation experiment water tank, and adjusting function is good, stable operation, and structure is simple, easily manufactured and be convenient to the experimental conditions observing tank inside.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of Novel circulation experiment water tank, and this circulation experiment tank, by automaton, changes effective actual internal area automatically, effective minimizing boundary layer departs from, make the even acceleration or deceleration of water flow inside, increase work efficiency, reduce costs.
In order to solve the problem, the present invention is achieved through technology,
A kind of Novel circulation experiment water tank, comprises U-shaped bend pipe, airfoil type flow deflector, bolt, flange, woven wire, straight tube, band radian tapered tube, minor diameter straight tube, U-shaped tank and long cone-shaped tube.The overall material of tank is organic glass, and transparency is high, and physical strength is high, lightweight, is easy to processing; Airfoil type flow deflector resistance is little, effective control flow check rate of flow of fluid, and baffling characteristics is good; The tapered tube Bolted Flanged Connection of straight tube and band radian, convenient disassembly.Straight length installs woven wire, effectively the water vortex of coming in U-shaped bend pipe is resolved into little whirlpool, reduces the impact of tank, makes current be tending towards straight; Long cone-shaped tube effectively prevents boundary-layer lift-off in it; With the tapered tube of radian, become streamlined, effectively prevent the disengaging in boundary layer, and two ends are respectively with Flange joint, easy for installation, change easily.U-shaped tank is provided with axial flow pump, and for driving the water circulation in whole tank, lift is low, and flow is large, high efficiency.
Long tapered tube is coaxial with the straight section of U-shaped bend pipe and U-shaped tank, and tapering angle is 4 °.
Band radian tapered tube, adopts streamlined, prevents boundary layer from departing from and hole, local, makes uniform fluid flow accelerate to speed needed for experiment, reduces turbulivity and also make it not produce separation.
Arrange airfoil type flow deflector in U-tube, close outer thin in adopting during installation, spacing is the form of Geometric Sequence arrangement.
Woven wire is arranged on straight length, effectively the water vortex that U-shaped bend pipe is come is resolved into little whirlpool, reduces the impact of tank, makes current be tending towards straight.
Have employed technique scheme, the invention has the beneficial effects as follows:
The overall material of tank adopts organic glass, and quality is light, and processing and manufacturing is easy, and mechanical property is high; The design of airfoil type flow deflector, makes water conservancy diversion more stable; Straight length installs woven wire, effectively the water vortex that U-shaped bend pipe is come is resolved into little whirlpool, reduces the impact of tank, makes current be tending towards straight; U-shaped tank is provided with axial flow pump, and for driving the water circulation in whole tank, lift is low, and flow is large, high efficiency.
Therefore, the present invention is compared with existing circulation experiment tank, there is outstanding advantage be: the design of (1) streamlined tapered tube, effectively prevent boundary layer from departing from and hole, local, uniform fluid flow is made to accelerate to speed needed for experiment, reduce turbulivity and make it not produce separation, work efficiency is high; (2) airfoil type flow deflector becomes interior close outer thin Geometric Sequence, and exit velocity homogeneity is strong; (3) good, the stable operation of adjusting function, structure is simple, easily manufactured.
A kind of Novel experimental tank provided by the invention, structurally achieve adjustable, operationally achieve automatic control, in effect, flow velocity tends towards stability, for practical application provides great convenience, can the Experiments of Machanics of widespread use indoor water.
