Abstract

The utility model discloses a kind of return pipe integrating the steady water of varying head, comprise collecting-tank, keying platform, headstock gear, water tank, return pipe, steady boom lattice and support column, described return pipe comprises upper strata return pipe and bottom return pipe, bottom return pipe is fixed on water tank, steady boom lattice are connected with upper strata return pipe, and support column is positioned at below water tank.The utility model have simple to operate, can automatically regulate head as required, adopt steady water and simple, the time saving and energy saving feature of backwater integral pipe structure, be applicable to applying.

Description

A kind of return pipe integrating the steady water of varying head

Technical field

The utility model belongs to hydraulic engineering technical field, relates to a kind of return pipe integrating the steady water of varying head.

Background technology

When hydraulic test is done in laboratory, usually need constant (namely current are steady flow) that keep building upstream head, also require that head can change, to adapt to the situation of engineering reality a larger scope simultaneously; In addition, also should water-stabilizing board be set, to keep stable level, fluctuates little.Traditional way makes water level be difficult to automatically regulate as required, and extra stabilization works too increases expense.

Utility model content

The purpose of this utility model is the defect overcoming the existence of above-mentioned technology, the problem such as solve building head wide variation, backwater place keeps flow-shape stable, provide a kind of simple to operate, can automatically regulate head as required, adopt steady water and simple, the time saving and energy saving return pipe integrating the steady water of varying head of backwater integral pipe structure.Its concrete technical scheme is:

A kind of return pipe integrating the steady water of varying head, comprise collecting-tank, keying platform, headstock gear, water tank, return pipe, steady boom lattice and support column, described return pipe comprises upper strata return pipe and bottom return pipe, bottom return pipe is fixed on water tank, steady boom lattice are connected with upper strata return pipe, and support column is positioned at below water tank.

Compared with prior art, the beneficial effects of the utility model are:

The utility model directly adopts two pipes to overlap and uses, and forms two-tube movable water return pipeline, solves the problem that building change of water level is large in experimentation, need not regulate water level all back and forth at every turn, saves experiment and drops into; Steady boom lattice and return pipe are formed an entirety, steady drainage facility need not be built in addition, can conserve space and expense.

Fig. 3 is the top view of return pipe.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is described in more detail.

See Fig. 1-Fig. 3, a kind of return pipe integrating the steady water of varying head, comprise collecting-tank 1, keying platform 2, headstock gear 3, water tank 4, return pipe 9, steady boom lattice 5 and support column 6, described return pipe 9 comprises upper strata return pipe 7 and bottom return pipe 8, bottom return pipe 8 is fixed on water tank 4, steady boom lattice 5 are connected with upper strata return pipe 7, and support column 6 is positioned at below water tank 4.The utility model integrates the return pipe of the steady water of varying head, collecting-tank supplies water in order to feed tank and collects backwater, water tank is in order to heading up, keying platform is operating platform, headstock gear is in order to regulate the height of upper strata return pipe to realize the change of building head, bottom return pipe is fixed on water tank, its crest level is usually equal with zero head required for building, upper strata return pipe is movable, can move up and down to regulate backwater height, control head, steady boom lattice and upper strata return pipe are fixed together, constipation structure is simple on the one hand, directly can play the effect of steady water on the other hand well.

Preferably, have employed two pipes in upper strata and bottom nested, bottom is fixed structure, upper strata is bascule, can regulate head easily; Upper strata return pipe and steady boom lattice are fixed together, steady water better effects if.

According to the needs of building to head, make bottom pipe crest level equal with zero head elevation required for building, be directly fixed on bearing bottom bottom pipe, pipe extends in collecting system; Be inserted in bottom pipe with the pipe that diameter is smaller compared with bottom pipe and (be called upper strata pipe), form a two-tube movable water return pipeline; The leaf water-stabilizing board of grid is installed at pipe top, upper strata, directly puts in in bottom pipe, separation case does not occur bottom the pipe of upper strata; Start headstock gear, leaf for grid water-stabilizing board and upper strata pipe are mentioned simultaneously or fall, thus height when regulating backwater in allowed band; Backwater height obtains by being arranged on the electronic instrument opened and closed on platform, and this is highly also the head value required for building.Wherein, must be slow in lifting or descent, and notice that upper strata pipe is not separated with bottom pipe, in order to avoid affect flow-shape and test effect.

This return pipe is the return pipe integrating varying head, steady water, not only overcomes the way that tradition regulates head, saves time and expense, and integrates varying head, steady water, makes structure simple, easy to operate.

The above; be only the utility model preferably detailed description of the invention; protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses, the simple change of the technical scheme that can obtain apparently or equivalence are replaced and are all fallen in protection domain of the present utility model.

Claims

1. one kind integrates the return pipe of the steady water of varying head, it is characterized in that, comprise collecting-tank, keying platform, headstock gear, water tank, return pipe, steady boom lattice and support column, described return pipe comprises upper strata return pipe and bottom return pipe, bottom return pipe is fixed on water tank, steady boom lattice are connected with upper strata return pipe, and support column is positioned at below water tank.
