Embodiment
For summary of the invention of the present invention, Characteristic can be understood further, hereby exemplify following examples and be described in detail as follows:
Refer to Fig. 1, the present invention includes the cylinder barrel 5 being positioned at middle part, the upper frame 3 being positioned at cylinder barrel 5 top and the underframe 8 be positioned at bottom cylinder barrel 5, in cylinder barrel 5, be provided with piston 6, be provided with the valvular water delivering orifice 7 of band in the bottom of cylinder barrel 5 outer wall.Cylinder barrel 5 adopts water water sample for depositing, and water sample is released by water delivering orifice 7.
The water inlet 10 adopting water water sample is arranged on the roof of cylinder barrel 5, is inserted with the pull bar 4 that bottom is connected to piston 6 top, is provided with tapered end 9 at the top of pull bar 4 in this water inlet 10.Cylinder barrel 5, pull bar 4 and piston 6 three form the structure of syringe-like, when piston 6 and pull bar 4 move down, adopt water water sample and namely enter cylinder barrel 5 by water inlet 10.In order to avoid adopt parts that water water sample contacted with water sample by hydrophore pollute, the polytetrafluoroethylmaterial material manufacture that the roof of the parts that hydrophore can be contacted with water sample in the present embodiment as the inwall of cylinder barrel 5, the roof of cylinder barrel 5 and piston 6 adopts chemical property more stable, above-mentioned material can not adsorb and stripping oily substance, and therefore this hydrophore can also as the collection of oil-containing water sample.
The top and bottom of water inlet 10 are the uncovered of taper platform shape, and the lower end of tapered end 9 and pull bar 4 are equipped with cone seal platform with the connecting portion of piston 6, and two cone seal platforms coordinate with being positioned at the uncovered of top and being positioned at the uncovered of below respectively, realize sealing.When upwards pulling pull bar 4 to drive piston 6 to arrive upper extreme position, the cone seal platform at piston 6 top is inserted into the mouth of a river 10 and is arranged in the uncovered of below, and now cylinder barrel 5 is in sealing state, all keeps sealing in the process that whole hydrophore is transferred in water.When arrival predetermined depth, release pull bar 4 and piston 6 make both rely on self gravitation to decline, namely water sample enters in cylinder barrel 5, when pull bar 4 and piston 6 arrive lower limit position, the cone seal platform of tapered end 9 lower end is during to be inserted into above the mouth of a river 10 uncovered, cylinder barrel 5 is in sealing state again, and whole hydrophore reclaims in the process of rising and all keeps sealing state in water, the isolation that effectively ensure that extraneous water sample and gather between water sample.
Also be provided with at the top of upper frame 3 for blocking tapered end 9 and at the releasing mechanism making to unclamp under hammer effect tapered end 9, this mechanism is the key mechanism of this hydrophore action.
Fig. 2 and Fig. 3 illustrates the concrete structure of releasing mechanism 2, can find out: releasing mechanism 2 comprises the ring flange 2-8 affixed with upper frame body 3, is connected with the wireline adapter 1 be connected with wire rope at the top of ring flange 2-8.Wire rope is as the link between hull and hydrophore, and the length decontroled by measuring it can learn hydrophore current place depth information.In the present embodiment, adopt between wireline adapter 1 with ring flange 2-8 and be threaded, the convenience of erection & lift and demolition and maintenance.
Adopt in the bottom of ring flange 2-8 multiple socket head cap screw 2-9 to be connected with mechanism body 2-2, in mechanism body 2-2, be provided with horizontal axis hole, in this axis hole, be provided with push rod 2-4.Push rod 2-4 comprises elastic force acting section, thin diameter section and wide section, boss is provided with between elastic force acting section and thin diameter section, be arranged with push rod spring 2-3 at elastic force acting section, this push rod spring 2-3 employing is set in push rod 2-4 end and the lock screw 2-1 affixed with mechanism body 2-2 locks.
The vertical center pit through with axis hole is provided with in the bottom of mechanism body 2-2, tapered end 9 comprises the mandrel for inserting this center pit being positioned at top, mandrel is provided with horizontal via hole and by the through notch to this via hole in top, wherein the diameter of via hole is greater than the diameter of push rod 2-4 wide section, and the width of notch is greater than the diameter of push rod 2-4 thin diameter section and is less than the diameter of wide section.Wide section is provided with radial jack, the through pin-and-hole to axis hole is provided with in the bottom of mechanism body 2-2, bearing pin 2-6 is provided with in this pin-and-hole, bearing pin 2-6 upwards inserts in jack and can be fixed the lateral attitude of push rod 2-4, can be resetted by bearing pin 2-6 by push rod 2-4 when extracting in jack.
To the operating principle that tapered end 9 is fixed be: the mandrel of tapered end 9 upwards inserts in the center pit of mechanism body 2-2, the thin diameter section of push rod 2-4 is entered downwards in via hole by notch, laterally promoting push rod 2-4 makes wide section enter via hole, push rod 2-4 moves to until bearing pin 2-6 upwards can insert in jack locks, and now push rod spring 2-3 is in compressive state.
The operation of being extracted downwards by bearing pin 2-6 realizes by impacting releasing means.In the present embodiment, impact releasing means comprises the guide pole web joint 2-5 and bottom that are fixed in bearing pin 2-6 bottom and guide pole web joint 2-5 is affixed, middle part is positioned at the vertical through hole be opened on ring flange 2-8, top is connected with the guide pole 2-10 impacting ring 2-12, be arranged with guide pole spring 2-11 in the part of guide pole 2-10 between ring flange 2-8 and impact ring 2-12,2-12 is on a steel cord sheathed for impact ring.
To the operating principle that tapered end 9 discharges be: hydrophore will make hammer on a steel cord sheathed after stablizing under water, and locking makes the anti-loosing screw on hammer, and order of letting go makes hammer free-falling.Hammer is glided fast along wire rope, impact ring 2-12 forces guide pole 2-10 to move down under the impact effect making hammer, guide pole web joint 2-5 extracts bearing pin 2-6 downwards, rear push-rod 2-4 reset under the effect of push rod spring 2-3, namely thin diameter section moves to middle part, and now tapered end 9 is discharged under the effect of self gravitation.
In the present embodiment, in order to utilize mechanics principle better, realize only needing a very little impulsive force can discharge unidirectional comparatively heavy load, setting is optimized to the position relationship of such as lower component: the axis being parallel of bearing pin 2-6 and guide pole 2-10 and all perpendicular to the axis of push rod 2-4; The axis co-planar of push rod 2-4, pull bar 4 and bearing pin 2-6 three; Wire rope and the axis collinear both pull bar 4.
For the ease of implementing the movement of push rod 2-4 and the fixing operation of tapered end 9, be provided with the connecting link of square-section in the outer end of push rod 2-4 wide section in the present embodiment, on mechanism body 2-2, the outer end of axis hole is provided with the connecting hole of square-section, and connecting link is stretched out by this connecting hole and is provided with handle 2-7 in end.The effect that anti-throw-out lever 2-4 rotates also is played in the connecting hole of square-section and the cooperation of connecting link, and bearing pin 2-6 and jack more easily align.
Complete after adopting water, whole hydrophore is recycled to ground, can take afterwards to the water sample in cylinder barrel 5.Due under the effect of piston 6, pull bar 4 and water sample three gravity, cone seal platform on tapered end 9 be inserted into the mouth of a river 10 uncovered in achieve sealing, therefore directly to open when valve discharges water water sample can not out, must first on carry piston 6 and make to recover normal pressure in cylinder barrel 5.In the present embodiment, be also provided with in the bottom of underframe 8 can turn, for the jackscrew 11 by piston jack-up.The fine motion being realized piston 6 by turn jackscrew 11 is risen, and removes being sealed and matched between cone seal platform and water inlet 10.
