Abstract
The utility model discloses an underwater sampler which comprises a steel pipe, a piston and a sampling cylinder barrel. The steel pipe is divided into two sections which are connected through a joint, the lower end of the steel pipe is fixedly connected with the sampling cylinder barrel, the piston is mounted in the sampling cylinder barrel, a piston pushing rod connected above the piston is arranged in the steel pipe, a ball valve and a ball valve handle are mounted on the upper portion of the steep pipe, and a handle is fixedly arranged outside the middle of the steel pipe. The design principle of the underwater sampler includes that underwater silt is extracted under the vacuum action. The underwater sampler is simple in structure, and can collect the underwater silt in deep water.
Description
Technical field
The utility model relates to a kind of sampling thief, refers in particular to a kind of multi-functional, convenient, practical negative pressure of vacuum dredge.
Background technology
Whether research rivers, water body in lake receive environmental pollution, pollution level and transition evolution rule, are to receive the scientific research task that country payes attention at present.Deep day by day along with Study of Water Environment, research contents is also more careful thereupon, concrete, requires also higher.But no matter in which way research all must be extracted water quality liquid and water-bed drift, and carried out the effective constituent check analysis in the laboratory from water body.But the thing, the particularly depth of water of how extracting drift from the darker bottom and be the part difficulty surpass more than 1 meter, from water body, gather just difficulty more of water-bed sample.Based on this problem that this specialty often runs into, develop and a kind ofly be applicable to that the negative pressure of vacuum dredge of getting silt, fine sand, middle fine sand and mud grass potpourri at the bottom is necessary.
The utility model content
The technical matters that the utility model will solve provides a kind of dredge, and this dredge is only applicable to water-bed silt, fine sand, middle fine sand and mud grass potpourri situation, is not suitable for the collection requirement of bulky grain sandstone.Sampling head contacts with water (river, lake) bottom surface, has advantage simple in structure, easy to use, can satisfy the requirement that the depth of water is no more than 5 meters water-bed silt collected specimens basically.
The technical matters that the utility model will solve is realized by following scheme: dredge; Comprise steel pipe, piston, sampling cylinder bucket, it is characterized in that: said steel pipe is divided into two-section and is connected by interface, and its lower end is fixedly connected sampling cylinder bucket; Dress piston in the sampling cylinder bucket; The piston push rod that the piston top connects places in the steel pipe, and a ball valve and ball valve handle are equipped with in steel pipe top, and steel pipe middle part external fixation has handle.
The utility model also comprises following scheme: saidly place piston push rod middle part in the steel pipe to be with two guide collar to contact with steel pipe.All vertically respectively have 2-4 air hole on said piston and the guide collar.Said sampling cylinder bucket lower end four circles are the sampling spoon mouth, and the cylinder bucket of being convenient to take a sample can insert in the water-bed drift effectively, quickly and easily.
The principle of work of the utility model: dredge is carried piston to peak before extracting silt, opens ball valve, dredge is vertically inserted in the water-bed silt again, promptly is full of water-bed silt in the sampling spoon mouth.Again in steel pipe, filling with clear water through ball valve; Ball valve handle is closed in rotation; The dredge steel duct makes through the air hole on guide collar and the piston and forms vacuum negative pressure condition in the steel drum; Sampling cylinder bucket promptly is filled silt, and the lifting handle of putting forth one's strength is again left the water dredge, accomplishes water-bed sampling process.Behind bottom proposition dredge; Lie in ground and open the ball valve switch; Lay down the upper half of ball valve, ball valve handle and steel pipe, pour out the clear water in the ball valve 9, in addition pusher grip is inserted in the piston push rod slot; About slightly the rotating push-rod handle put forth one's strength again and promote downwards, can take out water-bed silt sample.
The advantage of the utility model:
1, the sampling spoon mouth of dredge is convenient to insert effectively, quickly and easily in the water-bed drift.
2, have only when the negative pressure of vacuum in the sampling cylinder bucket is big, can will fill its interior drift from the bottom complete extracting.
3, when water depth surpasses 1 meter, can increase the steel pipe extension rod to guarantee to get water-bed silt sample.
4, be provided with two guide collar in the steel pipe, to guarantee the stability of piston push rod.
5, simple and reasonable, operation is convenient, and it is complete to take a sample, and the sampling effect is satisfactory.
When if 6 dredges insert the water-bed not enough degree of depth, can be at the top of ball valve pad one wooden unit, pound downwards with the rubber hammer and to make it reach desired depth.
Description of drawings
Fig. 1 is the one-piece construction synoptic diagram of dredge.
Fig. 2 is the one-piece construction synoptic diagram (lay down ball valve, ball valve handle and steel pipe the upper half, pusher grip is inserted in the piston push rod slot) of dredge.
Embodiment
As shown in Figure 1, dredge comprises steel pipe 1, sampling cylinder bucket 2, piston 3; Steel pipe 1 is divided into two-section and is connected by interface 4; Its lower end is fixedly connected sampling cylinder bucket 2, dress piston 3 in the sampling cylinder bucket 2, and the piston push rod 5 that piston 3 tops connect places in the steel pipe 1; Piston push rod 5 middle parts are with two guide collar 6 and contact with steel pipe 1, to guarantee the stability of piston push rod 5.All vertically respectively have 4 air holes 7 on piston 3 and the guide collar 6.A ball valve 8 and ball valve handle 9 are equipped with in steel pipe 1 top, and steel pipe 1 middle part external fixation has handle 10.Sampling cylinder bucket 2 lower ends four circles are sampling spoon mouth 11, and the cylinder bucket 2 of being convenient to take a sample can insert in the water-bed drift effectively, quickly and easily.
As shown in Figure 2; Behind bottom proposition dredge, lie in ground and open ball valve 8 switches, lay down the upper half of ball valve 8, ball valve handle 9 and steel pipe 1; Pour out the clear water in the ball valve 8; In addition pusher grip 12 is inserted in piston push rod 5 slots, about slightly rotating push-rod handle 12 put forth one's strength again and promote downwards, can take out water-bed silt sample.
Claims (4)
1. dredge; Comprise steel pipe, piston, sampling cylinder bucket, it is characterized in that: said steel pipe is divided into two-section and is connected by interface, and its lower end is fixedly connected sampling cylinder bucket; Dress piston in the sampling cylinder bucket; The piston push rod that the piston top connects places in the steel pipe, and a ball valve and ball valve handle are equipped with in steel pipe top, and steel pipe middle part external fixation has handle.
