Embodiment
Further illustrate the utility model below in conjunction with drawings and Examples, in accompanying drawing, dimensional units is all mm.
Embodiment 1 sediment sampler
As shown in Figure 1, sediment sampler, is made up of connecting link 1, stopple coupon 2, gravity drop hammer 3, stressed fixture splice 4, piston firmware 5, piston pad 6 and rubber piston 7.
As shown in Fig. 2 A-1, Fig. 2 A-2, Fig. 2 B-1 and Fig. 2 B-2, connecting link 1 is sampled metal material processing, length is determined according to the degree of depth of sampling, directly can use the pricker feeler lever in survey, Main Function connects gravity drop hammer, stressed fixture splice, piston firmware, piston pad, rubber piston, by connecting the water area sampling lengthening and can realize different depth.Each connecting link length is 50cm ~ 100cm, determines quantity and the size of connection according to the degree of depth of water body.Fig. 2 A-1, Fig. 2 A-2 are single connecting link, and Fig. 2 B-1 and Fig. 2 B-2 is extension rod.
As fig. 5 a and fig. 5b, stressed fixture splice 4 is cylindrical, and adopt stainless steel processing, axle center has through hole 41, and stressed fixture splice 4 is enclosed within connecting link 1, and its lower surface is fixedly connected with stopple coupon 2 one end.Main Function connects and protection clear PE stopple coupon, for the downward landing of gravity drop hammer provides stressed support, evenly transmits the impulsive force that stopple coupon is subject to.Detailed dimensions is shown in Fig. 5 A and Fig. 5 B.
As shown in Figure 3 A and Figure 3 B, stopple coupon 2 selects the clear PE tubing of thin-walled, be fixed on stressed fixture splice lower end, Main Function is sampling, because finding out during transparent sampling that sample is taked whether success, sample taking rate and taked the change etc. of sample different depth color, detailed dimensions is shown in Fig. 3 A and Fig. 3 B.During actual samples, the thickness that can sample as requested chooses the stopple coupon of different length.
As shown in Figure 4 A and 4 B shown in FIG., gravity drop hammer 3 is cylindrical, heavy 10kg, its axle center has through hole 31, and gravity drop hammer is enclosed within connecting link, is power resources main when taking sample, after rising to certain altitude along connecting link, downward landing applies gravity, passes to bottom stopple coupon by stressed fixture splice by strength, and stopple coupon to be entered under water body more deeply and harder dirt bed.Detailed dimensions is shown in Fig. 4 A and Fig. 4 B.
The front end of connecting link 1 is stretched in stopple coupon 2 through gravity drop hammer 3 and stressed fixture splice 4 successively, and is spirally connected with the piston component screw thread be arranged in stopple coupon 2.Gravity drop hammer 3 and stressed fixture splice 4 with connecting link 1 for be slidably connected.
Piston component comprises piston pad 6, rubber piston 7 and piston firmware 5, and piston component can slide along stopple coupon 2 tube wall and keep the impermeability inside and outside piston component.
As shown in Figure 6 A and 6 B, piston pad 6 is the sheet rubber that a center has through hole 61, is mainly fixed piston degree of tightness, plays good sealing function during sampling.Detailed dimensions is shown in Fig. 6 A and Fig. 6 B.
As shown in figures 7 a and 7b, rubber piston 7 is annular, adopts the elastomeric material processing of high-quality, mainly plays the effect of enclosed sampling pipe.Detailed dimensions is shown in Fig. 7 A and Fig. 7 B.
As shown in Figure 8 A and 8 B, piston firmware 5 top has screw thread 51 and is spirally connected with connecting link 1 front end.The Main Function of piston firmware 5 is fixed piston.Its underpart 52 shape is taper, dispersibles the pressure to mud layer when entering superficial part mud layer.Detailed dimensions is shown in Fig. 8 A and Fig. 8 B.
The upper end of piston firmware 5 is spirally connected with connecting link 1 front end screw thread through rubber piston 7 and piston shim through bore 61 successively.Piston firmware 5 pairs of rubber pistons 7 apply axle pressure makes it near piston pad 6.When tightening connecting link 1 or piston firmware 5 further, rubber piston 7 is because being subject to the axle pressure applied between piston firmware 5 and piston pad 6, the diameter of rubber piston 7 becomes large, make the air exclusion of rubber piston about 7 in stopple coupon 2, and rubber piston 7 and stopple coupon 2 is fixed together; When oppositely unscrewing, the diameter of rubber piston 7 diminishes, then piston can slide at stopple coupon 2.
The method of operating of sediment sampler:
1, as shown in Figure 9, with artificial or rope, sampler is slowly put into water, sampler enters mud layer under gravity.The hand steered sampler of one people, gravity drop hammer is moved 30-50cm along on connecting link by a people, then allows gravity drop hammer freely glide or manually applies certain pressure simultaneously, the stressed fixture splice of hammering, sensation stopple coupon stopple coupon is slowly pressed in mud layer, repeats aforesaid operations, to down can not go deep into mud layer again.Manually screw connecting link, seal the end opening of sampling pipe rubber piston, in the official jargon space of piston and bed mud sample room, form an airtight space, slowly sampler is left the water, and keep vertically.Now directly can observe the sampling effect of bed mud.
2, back knob connecting link, unclamps fastening piston, and bed mud sample is pushed bed mud sample collection device, namely completes and once samples.
3, available cutter (metal or plastics) on-the-spot segmentation cutting bed mud sample is needed according to research.Or by two silica gel plug jam-pack of whole stopple coupon, be directly sent to laboratory.
4, after each sample collection completes, sampling thief is cleaned.
