Description

The bed mud collector

Technical field

The utility model relates to the device for treating sludge technical field, especially a kind of bed mud collector.

Background technology

The phenomenons such as existing bed mud collector, because of the sampling time and effort consuming that poor structure causes, runs into chad substrate or difficult with the hydrophyte bottom characteristics sampling, and sampling spot is difficult to determine, blindness is large, and sampling precision is poor.

The utility model content

The utility model, for the deficiencies in the prior art, proposes a kind of bed mud collector, and is effective, efficient, convenient.

In order to realize above-mentioned utility model purpose, the utility model provides following technical scheme: a kind of bed mud collector, comprise taper bit, cylinder, device lid and hold bar, being welded as a whole with described cylinder one end at the bottom of the cone of described taper bit, described device lid is threaded with the other end of described cylinder; The described bar of holding is welded on described device and covers; Described cylinder outer wall is provided with spiral groove, described spiral groove near described device Gai Yiduan be provided with described cylinder in be communicated with enter the mud hole.

Further, described taper bit top is provided with two apertures.

Further, described device covers and is provided with through hole.

Compared with prior art, the utlity model has following advantage: this bed mud collector is made by stainless steel, is suitable for the collection of the various Sediments such as river, river, lake.The top of taper bit, being easy to inject needs the bed mud degree of depth that gathers, and conveniently locates; And be provided with again little pore on its top, be convenient to most of water in collected specimens and flow out, improve monitoring accuracy; What with tapered bottom end, be connected is wall cylindraceous, circular cone and cylinder connect, there is darker screw thread the wall outside, run-out(of thread) is provided with into the mud hole, during sampling along the screw thread rotation bottom sampler, sample will enter in cylinder by entering the mud hole along screw thread, and these screw threads just are equivalent to the road of bed mud sample; Cylinder and device lid are fixed together by screw thread, and device covers and is provided with air hole, and device covers to be fixed with and holds bar simultaneously, holding bar can be made as multistage and adopt latch to be fixedly connected with formation, can be conducive to gather the sample of the various degree of depth according to the length of the depth adjustment connecting link of sampling like this, also be convenient for carrying.

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 is the structural representation of holding bar.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described in detail, the description of this part is only exemplary and explanatory, should any restriction not arranged to protection domain of the present utility model.

A kind of bed mud collector as shown in Figure 1, comprise taper bit 2, cylinder, device lid 5 and hold bar 6, is welded as a whole with described cylinder one end at the bottom of the cone of described taper bit 2, and described device lid 5 is threaded with the other end of described cylinder; The described bar 6 of holding is welded on described device lid 5; Described cylinder outer wall is provided with spiral groove 3, described spiral groove 3 near described device lid 5 one ends be provided with described cylinder in be communicated with enter mud hole 4.Wherein, described taper bit 2 tops are provided with two apertures 1, as shown in Figure 2.Described device lid 5 is provided with through hole 51, as shown in Figure 3.

This bed mud collector integral body is made by stainless steel, is suitable for various water body middle-shallow layers or, than the collection of deep layer bed mud sample, is bottom sampler a kind of simple in structure, easy to operate.

Embodiment

(1) size of bed mud collector

Bed mud collector storage sample part radius is 80mm, the high 180mm of centrum part, the high 260mm of cylindrical part, height overall 340mm; Advance mud pore radius 30mm; Covering thick is 10mm; The length of extension bar is 600mm; Mud containing amount is 5.93L.

(2) main part

This bed mud collector is made by stainless steel, topmost is the taper hollow design to be easy to location; Taper bit 2 is provided with two apertures 1, is convenient to enter the deep layer bed mud, and the water in institute's collected specimens can flow out from described aperture 1, improves the sampling accuracy rate; Taper bit 2 welds together, connects with columnar wall, has darker grain design to enter bottom sampler for the bed mud that gathers on wall, is " road " of the bed mud that gathers; The tail end of texture is provided with circular mud inlet, and the diameter of this mud inlet is identical with the width of thread, mud inlet and sampling thief inner chamber UNICOM, and when the rotating acquisition device, bed mud is threaded to mud inlet with texture, thereby enters collector.

(3) hold the bar part

, by thread connection, cover and be provided with through hole 51 between collector main body and lid, be convenient to ventilation, avoiding producing vacuum affects collecting efficiency; The lid of collector with hold bar 6 and weld together, come off while preventing from sampling, holding bar 6 can conversion free according to sampling depth, holding bar 6 can be multi-segment activity and connects and composes, each section held between bar fixing with a latch 7, and latch 7 had both played fixing effect, can regard handle again.Can meet the sample requirement of different depth like this, be convenient for carrying again.

The principle of work of bed mud collector

The convenient sampling of the design of taper bit 2 tapers location, be not subjected to the impact than hardground, and the skin of cylindrical wall is provided with spiral groove 3, and along the direction rotation collector of spiral, bed mud will enter collector by entering mud hole 4 along screw thread.Adopting between mud main part and device lid 5 of this collector is threaded connection, described device lid 5 is provided with breeder tube 51, device lid 5 with hold bar 6 and weld together, can not come off during sampling, the described bar 6 of holding can be according to the depth adjustment of sampling, hold bar and be connected with a latch 7 with holding between bar, be convenient for carrying.

During sampling, according to sampling depth, connect and hold pole length, collector arrives desired depth, the design of taper is accurately located, then by the direction rotation bottom sampler of handle along texture, bed mud will enter collector from mud inlet along the texture on wall, and air is overflowed by the vent port that covers.Mention collector, the most of water in bed mud can be discharged from two apertures of conical lower portion.Turn on lid after sampling finishes and can take out the bed mud sample of collection.

The operation steps of bed mud collector

(1) select the length of extension bar according to sampling depth, hold long 0.6 meter of bar for every, multistage is held between bar 6 and is connected with latch 7, together with then the main body of bottom sampler and device lid 5 being spun on by screw thread;

The collector that (2) will connect inserts the bed mud degree of depth of required collection, then along the direction of screw thread, passes through handle (latch) rotating acquisition device, and bed mud will enter collector along screw thread;

(3) after the bed mud collection finishes, promote bottom sampler, turn on lid and can obtain the bed mud sample that gathers.

The characteristics of bed mud collector

(1) design of collector wall texture has improved sampling efficiency, in the larger bed mud of water cut, grabs the mud sample that bucket grabs and will miss, and adopt the column bottom sampler of pull of vacuum because washiness is inhaled incessantly, and this bed mud collector has been avoided this defect.

(2) simple to operate, operating personnel one people gets final product, and the skilled operation time is short, is easy to carry about with one and transports.
