Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
Embodiment one: as shown in Figure 1, the present embodiment two channels multi-stage jet sampling tail pigtail, comprises twin wall emitter lateral body 1 and is coated at the housing 2 of twin wall emitter lateral body 1, rotatable engagement between described housing 2 and twin wall emitter lateral body 1;
Described twin wall emitter lateral body 1 comprises outer tube wall 101 and inner tubal wall 102, circular channel 3 between described outer tube wall 101 and inner tubal wall 102 is at pipe body back-end closure, the front end of described outer tube wall 101 and inner tubal wall 102 is provided with the connection structure connecting double-wall drill pipe, and the connection structure in the present embodiment comprises the outside screw being arranged on outer tube wall 101 front end and the annular projection being arranged on inner tubal wall 102 front end;
Described housing 2 is provided with the first rapid-acting coupling 4 being connected with the circular channel 3 between outer tube wall 101 and inner tubal wall 102 and the 2nd rapid-acting coupling 5 that the pore with inner tubal wall 102 is connected;
Described inner tubal wall 102 is provided with in the pore of inner tubal wall 102 injection injector 6, the injection direction of described injector 6 is towards the pore outlet side of inner tubal wall 102.
In the present embodiment, described injector 6 is annular ejector, described annular ejector comprises a spray tube body 601 and penetrates medium inlet 602 along some the drawing that caliber circumference is arranged in parallel at spray tube body exit end, described in draw the circular channel 3 penetrated between medium inlet 602 with outer tube wall 101 and inner tubal wall 102 and be connected;Described inner tubal wall 102 is divided into front section and rear section, and the front end of described annular ejector 6 is connected with the rear end of front section of inner tubal wall, and the rear end of described annular ejector 6 is connected with the front end of rear section of inner tubal wall.
When the present embodiment two channels multi-stage jet sampling tail pigtail is sampled, double-wall drill pipe is connected to the front end of twin wall emitter lateral body 1, pressurized air enters the circular channel 3 between outer tube wall 101 and inner tubal wall 102 from the first rapid-acting coupling 4, enter the pore of inner tubal wall 102 through the front end of double-wall drill pipe from sampling drill bit again, thus sample is carried along double-wall drill pipe inner tubal wall pore. Owing to the pressurized air in circular channel 3 also sprays at a high speed to the pore of inner tubal wall 102 through injector 6, thus make the pore of inner tubal wall 102 forms negative pressure, and then the air-flow velocity carrying sample in inner tubal wall 102 pore can be increased, ensure sampling degree of depth increase situation under still can be quick, enough sample is exported.
Annular ejector 6 in the present embodiment is the single-stage annular ejector comprising a spray tube body 601, certainly in different embodiments, described injector 6 also can be the multi-stage annular injector comprising some spray tube bodies 601, as shown in Figure 2, each spray tube body 601 head and the tail of described multi-stage annular injector connect in turn, adopt series ejectors can improve the negative pressure in inner tubal wall 102 pore further, and then can faster sample be exported.
Embodiment two: as shown in Figure 3, the difference of the present embodiment and embodiment one is injector centered by described injector 6, described central-injection device 6 is for being arranged in the spray tube of inner tubal wall 102 pore, and the circular channel 3 penetrated between medium inlet with outer tube wall 101 and inner tubal wall 102 of drawing of described spray tube is connected; Other structure of the present embodiment is identical with embodiment one, does not repeat them here. Central-injection device in the present embodiment is the single-stage central-injection device being made up of single root spray tube, certainly the central-injection device described in implementing in difference also can for being axially arranged in juxtaposition the multilevel center injector (as shown in Figure 4) formed by some spray tubes along inner tubal wall 102, series ejectors can make to form higher negative pressure in inner tubal wall 102 pore, is conducive to the conveying of sample.
What finally illustrate is, above embodiment is only in order to illustrate the technical scheme of the present invention and unrestricted, although with reference to better embodiment to invention has been detailed explanation, it will be understood by those within the art that, the technical scheme of the present invention can be modified or equivalent replacement, and not departing from objective and the scope of technical solution of the present invention, it all should be encompassed in the middle of the right of the present invention.
