Embodiment
Referring to Fig. 1～Fig. 5, the utility model comprises multistage many components pick-up unit 1, the pick-up unit of component more than each grade 1 includes wave detector assembly 12 and the air bag assembly 13 that is loaded in the cylinder body 11, and this air bag assembly 13 is by air bag 2 and be wrapped in its outside multilayer shrink sleeve 3 and constitute.The two ends of air bag 2 respectively are provided with blow vent 21, and the blow vent 21 of the air bag of adjacent cells 1 all interconnects by snorkel 4.Air bag 2 is directly inserted in the body 11, and has a window 5 corresponding with air bag 2 on the barrel of body 11, so that after air bag 2 inflations, the air bag that makes expansion is partly from described window 5 outside projections, to prop up the borehole wall.Cylinder body 11 is divided into two parts, and a part is the part of placing air bag assembly 13, and another part is the part of placing wave detector assembly 12, these two part seal isolation.In addition, every grade body 11 two ends are equipped with by drop handle 6 and are connected the bindiny mechanism that the connecting rope 7 (or chain, bar etc.) between them is formed.The signal wire (cable) 8 of every grade wave detector assembly 12 all passes the body 11 of above wave detector assembly 12 at different levels, guides to outer wellhead separately and is connected with other supporting seismic wave analysis equipment (not shown).
Fig. 4 is that multistage many components pick-up unit 1 of the present utility model is put into the detection well, not the synoptic diagram of the situation of inflation in air bag 2.Owing to the air bag unaerated, therefore can adjust the measuring position of wave detector easily by mobile rope.
Fig. 5 shows the situation when wave detector is actual to be used, and this moment, the air bag 2 of wave detector 1 was inflated.As can be seen from the figure, owing to air bag 2 has been inflated, thereby wave detector body 11 is closely contacted with the borehole wall of measuring position by the air bag of heaving 2.
