The technical solution of the utility model is such: it comprises releasing means and sampling apparatus, wherein sampling apparatus comprises connecting pipe and carries pipe, connecting pipe and carry pipe by flange coupling, carry pipe top and propose piece and releasing means connection by afterbody, the lower port of connecting pipe is provided with cutter head, at the middle part of connecting pipe the sealing sampler is set.
The sealing sampler comprises pressurized capsule; connecting pipe is divided into; following connecting pipe; and on; following connecting pipe connects with pressurized capsule respectively; in pressurized capsule, be provided with on; the sample hose of following connecting pipe butt joint; a side is provided with the drive unit of translation sample hose in pressurized capsule; opposite side is provided with the drive unit of sealed sample pipe; the drive unit of translation sample hose is the translation hydraulic cylinder; the drive unit of sealed sample pipe is the sealing liquid cylinder pressure; two hydraulic energy-accumulating jars are set carrying on the pipe; the hydraulic energy-accumulating jar links to each other with the sealing liquid cylinder pressure with the translation hydraulic cylinder respectively; unlatching by oil circuit switch control hydraulic cylinder; at sample hose one side setting and its auxiliary tube side by side; sample hose is connected by spring with auxiliary tube, and the spring afterbody is connected with translation hydraulic cylinder piston rod termination, and the track of realizing sample hose and auxiliary tube translation is set on the pressurized capsule inwall; at the outer setting protective cover of pressurized capsule, protective cover is set to arrow-shaped.
The utility model is owing to adopted the translation of hydraulically powered sample hose original position and the sealing drive unit, so automaticity and reliability are higher; In addition, sample hose translation and seal process are all finished in position in the sampling process, and sample hose adopts the three-decker of two-layer PPR pipe therebetween heat-insulation layer, can realize original position pressure tight sampling truly.
Description of drawings
Fig. 1 is an one-piece construction synoptic diagram of the present utility model;
Embodiment
One-piece construction of the present utility model as shown in Figure 1, it comprises pressurized capsule 3, being provided with in the pressurized capsule 3 can be along the sample hose 7 and the auxiliary tube 5 of slideway translation, sample hose and auxiliary tube link together with the rubber-like steel bar, wherein, sample hose is for partly connecting, steel bar links to each other with the piston rod end of translation hydraulic cylinder 4, sealing liquid cylinder pressure 8 is installed on the plate of cabin up and down of pressurized capsule, after the pipe of adopting sample is pushed into sealing station by hydraulic cylinder 4, rubber plug and spring clamp are depressed in 8 actions of upper-lower seal hydraulic cylinder, form sealing; The pressurized capsule lower end links to each other with following connecting pipe 2, and cutter head is equipped with in following connecting pipe lower end; Pressurized capsule top links to each other with last connecting pipe 9, last connecting pipe by flange 10 with carry pipe and 12 link to each other, and plumbous balancing weight 11 is fixed on the flange 10; Two energy storage tanks 13 utilize steel band to be fixed on and carry on the pipe 12; carry pipe 12 upper ends and link to each other, two oil circuit switches 14 are housed on the tail piece, the track of realizing sample hose and auxiliary tube translation is set on pressurized capsule 3 inwalls with tail piece 15; at the outer setting protective cover of pressurized capsule, protective cover is set to arrowhead form.
During actual the use, utilize delivery vehicle such as ship that this sampling thief is transported to earlier and specify the marine site, then, utilize boom hoisting that it is rendered in the sea, before the release, sampling thief hangs on the releasing means, slowly transfer with releasing means, when the fixed high counterbalance weight of the potential energy of delivery system touched the seabed, the balance stem of delivery system was unbalance, sampling thief comes off from releasing means 17, because cutter head is a point, protective cover is an arrow-shaped, so equipment inserts the marine bottom sediment layer fast, so sediment enters down connecting pipe 2 from cutter head 1, in sample hose 7 and the last connecting pipe 9, utilize then and draw wire rope 16 on the boat-carrying winch; On be pulled through in the journey, with the oil circuit switch opens of translation hydraulic cylinder 4,4 actions of translation hydraulic cylinder are pushed into sealing station with sample hose 7 to short boost line earlier, this moment, auxiliary tube occupied the sample hose origin-location; Draw in the continuation, another boost line is with the oil circuit switch opens of sealing liquid cylinder pressure 8, and 8 actions of sealing liquid cylinder pressure are depressed realization sealing fidelity with rubber plug; Draw in the continuation, main rope is pulled out sampling thief integral body, is pulled through in the journey on continuing, because the existence of auxiliary tube 5, seawater will wash away all the other sediments in the pipe, realizes the self-cleaning of sampling thief; At last, whole sampling thief is hung on the ship, the sealing liquid cylinder pressure is restored, open the side hatch door and take out sample hose, empty sample hose is pushed, close hatch door, the translation hydraulic cylinder is restored, can sample next time.
As from the foregoing, compared with prior art, this utility model is owing to realized gordian techniquies such as original position translation and sealed sample pipe, and sample hose adopts three layers of insulation and rubber stopper seal, is real original position pressure tight sampling; And carry energy storage equipment, need not on the ship power and can finish sampling process, easy and simple to handle, the reliability height.
The parts of the above sampling thief all adopt resistant material to make.Of the present utility model top layer marine bottom sediment fidelity sampler can be widely used in the sampling field of marine bottom sediment.
