The specific embodiment

For the utility model architectural feature and technique effect better are described, the utility model specific embodiment is done an introduction in detail below in conjunction with accompanying drawing and Reference numeral:

As shown in Figure 1; Described single probe telescoping ram is supported on the support assemblies assembly on the borehole wall and can be supported on the borehole wall equally and probe load module that sampling probe is installed constitutes with being installed on the agent structure by agent structure in the down-hole; Two support assemblies assemblies that are arranged side by side are installed in the downside of agent structure; Single probe telescoping ram is arranged on the top of agent structure, and is positioned at the centre of two support assemblies assemblies so that overall structure is more stable when underground work; Load module is piston/cylinder to described support assemblies assembly with probe; Said main body mechanism is made up of main matrix and the last over cap that is installed on main matrix 1 top; Last over cap is connected with main matrix through screw; The support assemblies assembly opens and leans on the borehole wall with the piston of probe load module during work, and then realizes the fixing action in down-hole.

As shown in Figure 2; Described support assemblies assembly includes part and supports overcoat 5; And part is supported overcoat 5 be fixed in the big fixed cap 6 on the agent structure; And the transition piston 32 that is arranged at the outer support set of part 5 inside; And the inner carrier post 9 that is arranged in the transition piston constitutes, and the outer support set of said part thoroughly separates the oil 18 of opening in the inner chamber 31 with down-hole slurry through first packed-piston 15 and second packed-piston 17, and said transition piston 32 opens oily 18 through the 3rd sealing ring 7 and the 4th sealing ring 16 with the hydraulic oil in the inner chamber thoroughly to be separated with down-hole slurry; Said inner carrier post 9 thoroughly separates the hydraulic oil in the inner chamber with down-hole slurry with the 6th packed-piston 13 through the 5th packed-piston 12; The termination, bottom of said inner carrier post 9 is provided with top cover 11, and in the present embodiment, said top cover passes through screw on inner piston rod 9; And in the present embodiment, said big fixed cap is connected through screw thread and part support overcoat 5.

Shown in Figure 2 like Fig. 1, in the support assemblies assembly,, opens in the oil circuit hydraulic oil when getting into; Get in the asphalt channel 2, get into then in the inner chamber 31, along with increasing of hydraulic oil; The oil 18 that opens in the inner chamber 31 increases gradually; Pressure increases gradually, thereby promotes inner carrier post 9 and transition piston 32 outwards motion together, and then realizes the process of opening of support assemblies assembly.Shrink in the oil circuit when hydraulic oil gets into, while passing hole channel 16 gets in the inner chamber 34 with duct 33 in the hydraulic oil entering inner chamber 4, along with shrinking oily the increasing of oil circuit mesohigh; Inner chamber 34 pressure increase; Pushing inner carrier post 9 and transition piston 32 push the hydraulic oil in the inner chamber 31, under the effect of electromagnetic valve simultaneously towards open counter motion; Open the oil circuit conducting; The conducting of this moment just makes the hydraulic oil in the inner chamber 31 be back in the original inner chamber, and the pressure in the inner chamber 31 reduces, and does not have open position originally thereby make inner carrier post 9 and transition piston 32 return to.

As shown in Figure 3; Said probe load module includes external seal fixed cover 36 and the external seal fixed cover is fixed in the following fixed cap 25 on the agent structure; Be arranged at 36 inner the penetrating piston 53 and be arranged at the sliding plunger 45 that penetrates internal piston of external seal fixed cover; The upper end of said sliding plunger 45 is fixed with sealed chassis 47 through screw thread, sealed chassis 47 also be provided with rubber gasket 48 with the ground contact jaw, said rubber gasket is adhered on the sealed chassis; Said external seal fixed cover 36 opens oil 28 through

sealing ring

42,43,44 with the inside in the inner chamber 35 with following fixed cap 25 and separates with the down-hole slurry geodetic; Said probe load module also includes filter pipe 55 and filter pipe 55 is connected in down fixed cap 25 and is communicated in down the seal head 54 of the fluid passage 24 in the fixed cap 25, and said filter pipe 55 is through sliding plunger 45 and sealed chassis 47 and sealing mat 48.

Shown in Figure 3 like Fig. 1, in probe load module,, opens in the oil circuit hydraulic oil when getting into; And constantly flow in the inner chamber 35; Make the pressure in the inner chamber 35 increase, and then promote sliding plunger 45 and penetrate piston 53 setting in motions, and then drive sealed chassis 47 moves with sealing mat 48; Thereby directly touch borehole wall mud 49; Sealing mat 48 compresses with borehole wall mud 49 and borehole wall stratum 50, thus isolator layer fluid and F amalgam 51 and outside slurry fluid 52. formation fluids and F amalgam 51 through sealed joint pipe 21 entering in the fluid passage 20 of agent structure inside, thereby reach the purpose of sampling.Shrink in the oil circuit when hydraulic oil gets into, pressure oil gets into and shrinks oil-in 26, enters into duct 27 simultaneously; Along with the increase of pressure in the oil circuit, promote sliding plunger 45, penetrate piston 53 recovery, seal head 54 is threaded with following fixed cap 25; Fixed; Drive filter pipe 55 contractions along with penetrating piston 53, seal head 54 is extruded filter pipe 55 inner fluids, and finally sealed head 54 tops are concordant with filter pipe 55 tops.

The support assemblies assembly carries out with opening with contraction process of load module of probe simultaneously, but unqualified in the express delivery of opening and shrinking, and can make adjusting according to actual conditions.

Other embodiments of the utility model: 1, said support assemblies assembly does not have the transition piston, and it is to have bigger contraction and open stroke for the support assemblies assembly that the support assemblies assembly among first embodiment is provided with the transition piston; 2, said support assemblies assembly and the be provided with form of probe load module on agent structure are not limited to foregoing description, as long as can guarantee the normal operation of total in the shaft bottom.

The above only is a kind of preferred implementation of the utility model; Should be pointed out that for those skilled in the relevant art, under the prerequisite that does not break away from the utility model principle; Trickle modification and the improvement made also should be regarded as belonging to the protection domain of the utility model.
