The course of work of the present utility model:
First the disjunctor of dividing plate 6, big spring 7 and weight 8 is put into to cylindrical shell 10, the screwed end of pull bar 9 passes chute 29, is connected in the small sircle hole of weight 8.According to actual needs, choose the weight block 5 of right quantity, be placed on dividing plate 6, tighten upper cover 3, turn screw rod 2 until withstand weight block 5.Sampling push pipe 14 tops are kept off in cylindrical shell 10 by lower capping 13.According to gathering deepwater regions sediment layer thickness, choose the sampling extension tube 18 of right quantity, by direct 15, each sampling extension tube 18 is connected, and be connected successively by direct 15 will sample push pipe 14, the extension tube 18 of sampling and bottom tubes 20 of sampling.Choose sufficiently long stay cord 1, lie on draw ring 4.
Before gathering bed mud, vertically pull pull bar 9, until the vertical top of chute 29 is moving horizontally pull bar 9, to horizontal top, make big spring 7 be in contraction state.Hold stay cord 1, gradually device is put into to water, until reach the bed mud top layer, sampling pipe 181 is in continuing going down process, bed mud enters sampling pipe 181 makes non-return sheet 19 upwards rotate near sampling bottom tube 20 lower inner wall around turning axle 22, and withstand non-return sheet 19 by non-return sheet register pin 191, prevent that non-return sheet 19 too is adjacent to tube wall.Sampling pipe 181 is in continuing going down process, resistance can increase gradually, running speed can slow down, the running speed of the fast over-sampling pipe 181 of cylindrical shell 10 rate of sinking, the power that little spring 12 acts on sampling push pipe 14 upper ends increases gradually, little spring 12 is compressed gradually, rise gradually in the sampling position of push pipe 14 upper ends in cylindrical shell 10, until touch trigger 28 lower ends, continue to rise in the position of sampling push pipe 14 upper ends in cylindrical shell 10, trigger 28 lower ends are stressed, by rotating shaft 25 power transmissions to trigger 28 upper ends, trigger 28 upper end pushing drawing rods 9, until pull bar 9 slippage chute 29 upper ends, in pull bar 9 downslide processes, on pull bar 9, the disk jut can guarantee that weight 8 moves downward at cylindrical shell 10 cores, the energy of big spring 7 discharges, order about weight 8 bang sampling pipe 181 upper end cores, make sampling pipe 181 obtain larger in short-term impulsive force, accelerate the process of sampling, and can gather the former bed mud with certain degree of hardness.Adopt after the mud process completes bottom, use the rapid heaving mechanism of stay cord 1, in the process that sampling pipe 181 rises, in pipe, bed mud pushes non-return sheet 19 downwards, non-return sheet 19 is got back to rapidly the non-return sheet and is supported on 21, sheet rubber 23 on non-return sheet 19 covers the gap of 19 of non-return sheets, prevents that bed mud is from sampling bottom tube 20 bottom leaky.
When sampling push pipe 14 and the extension tube 18 of sampling be connected directly surface after, hold direct 15, loosening a little sampling push pipe 14, make to sample push pipe 14 lower ends and the sampling extension tube 18 upper ends form certain gap, corresponding with direct 15 finedraw, now, rubber ring 16 in sampling push pipe 14 can prevent that bed mud is from seepage gap, hold the handgrip of inserting shrouding 30, promote to insert in the finedraw of shrouding 30 insertions direct 15, tighten sampling push pipe 14, the push pipe 14 lower end rubber blankets 17 that make to sample are close to slotting shrouding 30 again, play the purpose of sealing sampling push pipe 14 bottoms.
Open lower capping 13, back out sampling extension tube 18, take off sampling push pipe 14, clog exhaust spillway hole 141 with rubber stopper, vertical placement is got up.Use pipe cap 31 seals the upper end of sampling extension tube 18, seals the direct of sampling extension tube 18 lower ends according to the mode that seals sampling push pipe 14 lower ends direct 15, successively according to the upper type segmentation, taking off the extension tube 18 of respectively sampling, and vertical placement.Finally, sampling bottom tube 20 covers pipe cap 31, the vertical placement.
After finishing a sampled point sampling, change sampling pipe 181, repeat aforesaid operations.
Above-described embodiment is only preferred embodiment of the present utility model, not limits according to this protection domain of the present utility model, therefore: all equivalences of doing according to structure of the present utility model, shape, principle change, within all should being covered by protection domain of the present utility model.
