Embodiment

Below in conjunction with accompanying drawing and practical implementation example a kind of unpowered adjustable hydrophone of straining of the utility model is done further explain.

Please see figures.1.and.2, the utility model unpowered adjustable strained levitation device 2 that hydrophone comprises the sliding guide 1 that is fixed on the reaction pool inner wall, slides along said sliding guide 1, is located in the said levitation device 2 and the tube seat 3 that catchments that is connected with said levitation device 2; The said tube seat that catchments sets out mill weir mouth 31, and its bottom sets out the mouth of a river 32; Also comprise the connection flexible pipe 4 that connects said water outlet 32, with said be connected that flexible pipe 4 is communicated with wear wall pipe 5, connect the said terminal electrically operated valve 6 of wall pipe 5 of wearing.

Said sliding guide 1 is fixed on the inwall in reaction pond through angle steel 8.

Said levitation device 2 also is a slag-blocking apparatus, adopts glue alternately to connect into the rectangle cabinet by four pvc pipe roads and four swan necks.

The said tube seat 3 that catchments is connected with said levitation device 2 through stationary installation.

Said stationary installation comprises clip 11, the adjusting bolt 13 on the pvc pipe road that is enclosed within levitation device 2.The pvc pipe road places clip 11 middle part circles, and the straight plate in the both sides of clip 11 is provided with screw, regulates end that bolt 13 passes the tube seat that catchments and passes the screw of the clip 11 1 ends tube seat 3 that will catchment again and link together with levitation device 2.Can regulate the phase place height of catchment tube seat 3 and levitation device 2 through regulating bolt 13, strain water speed thereby regulate.

The other end of clip 11 then is fixedly connected a sliding sleeve 7.Said sliding sleeve 7 is sleeved on the sliding guide 1, makes sliding sleeve 7 to slide up and down along sliding guide 1.At vertical direction, levitation device 2 receives the effect of buoyancy of water, and in the horizontal direction, levitation device 2 is fixing by sliding sleeve 7 again, make levitation device 2 along with the up-down of water level sink-float up and down, but the plane displacement can not take place.

To strain water depth in order controlling, also to comprise spacing lifting rope 9, be fixed on the fixed pulley 10 on the said angle steel 1, said spacing lifting rope 9 walks around said fixed pulley 10 and end is fixed on the said levitation device 2.Can control the degree of depth of levitation device 2 in the reaction pond through the length of adjusting spacing lifting rope 9, thereby water depth is strained in control.

Receive buoyancy effect to float on the water surface for avoiding connecting flexible pipe 4, guarantee that treating water discharges smoothly, be with anti-floating ring 14 on the said connection flexible pipe 4.Connect flexible pipe and select for use axial flexibility good, the pipeline that certain rigidity is radially arranged of its xsect avoids pipeline to receive hydraulic pressure and modification.

Said water outlet crest of weir 31 for drift angle down and the equilateral triangle aperture concordant with the medullary ray of the tube seat that catchments.

The utility model unpowered adjustable strained the water conservancy project of hydrophone, and to make flow process following:

SBR technology gets into and strains before the water conservancy project preface, and water outlet electrically operated valve 13 is in closing condition, and the levitation device 2 of the built-in tube seat 3 that catchments floats on the water surface.Catchment the water outlet triangle crest of weir 31 of tube seat 3 a little less than the water surface, and connection flexible pipe 4 fulls of liquid of draining become the vertical line shape under the effect of anti-floating ring 14.When beginning to strain water, at first open electrically operated valve 6, the liquid that connects the flexible pipe 4 and the tube seat 3 that catchments is discharged, cause the tube seat 3 inside and outside both sides of catchmenting to form waterhead, supernatant continues to flow into header groove 3 under the effect of waterhead.Subsequently since delivery flow greater than the flow that overflows into the tube seat 3 that catchments; Cause connect catchment tube seat 3 be connected flexible pipe 4 and become non-flowing full by flowing full; Correspondingly float slightly to equilibrium locations at buoyancy function low suspension device 2; Keep stable subsequently and also discharge supernatant outside the pond continuously, levitation device 2 vertically descends with the water surface under the effect of sliding sleeve 7 and sliding guide 1.Set depth is reduced in the reaction tank underwater, and levitation device 1 receives fixed pulley 10 and hangs on the water surface with spacing lifting rope 9 effects, stops to descend and straining water.After straining the end of water time, electrically operated valve 6 is closed, and after one section standby time, reaction tank begins water inlet, and levitation device 2 floats thereupon, gets into the next cycle of operation.

Anti-floating ring 14 is enclosed within and connects on the flexible pipe 4, and under the effect of gravity, is in the valley that connects flexible pipe 4 all the time, thereby avoids the latter to float, and guarantees that treating water discharges smoothly.

According to handling flow and straining the water time, regulate the relative height of tube seat 3 and levitation device 2 of catchmenting, thereby adjust the mill weir heights of roofs and strain water speed.

For a person skilled in the art, can make other various corresponding changes and distortion, and these all changes and distortion should belong within the protection domain of the utility model claim all according to the technical scheme and the design of above description.
