Technical field
The present invention relates to a kind of waters substrate and benthic investigation, monitoring device, specifically a kind of shallow water body bottom mud column-shaped sampling apparatus.
Background technology
In relating to the ecological studies such as pond, lake, the waters substrate monitoring such as coastal and benthic investigation, require as far as possible physics, the chemical property of research bed mud and perch biological minimizing to disturb, so, sediment sampler one of the equipment that is absolutely necessary.At present, there is numerous sediment samplers to utilize, but all can have some problems in concrete practical application, as grab bucket-type dredger is heavy, bed mud environment is easily damaged, to poor for applicability at the bottom of sposh; The shortcomings such as columnar sampler is how complicated by forming of being caused by delicate structure, and parts are numerous, and price is more expensive.Above problem, has affected the popularization of sediment sampler more or less, has increased the difficulty of the ecological bed mud sampling in field.
Summary of the invention
The object of the present invention is to provide a kind of simple in structure, be easy to processing and making, cheap, easy to operate shallow water body bottom mud column-shaped sampling apparatus.
In order to solve the problems of the technologies described above, shallow water body bottom mud column-shaped sampling apparatus of the present invention, the sampling pipe and the inserted link that is connected to sampling pipe top that comprise hollow cylindrical, one side of sampling pipe upper end is provided with osculum, sampling pipe lower end is set to the two parts that disconnect, between two parts that sampling pipe lower end disconnects, by two above connecting links, link together, also comprise the two-part elastic caoutchouc flexible pipe that a connection sampling pipe lower end disconnects, the diameter of elastic caoutchouc flexible pipe is greater than sampling pipe and the two ends up and down of elastic caoutchouc flexible pipe is pressed on respectively in the two-part cavity of sampling pipe lower end disconnection, the flexible silk rope of described elastic caoutchouc hose overcoat, wherein on a connecting link, be provided with roller bearing, on elastic yarn rope, be connected with a rope of walking around roller bearing.
On described inserted link, be connected with extension rod.
Described elastic yarn rope is round high resiliency steel wire, nylon rope or stay cord.
The central shaft of described roller bearing is horizontally disposed with.
Tool of the present invention has the following advantages:
1, little to bed mud disturbance, sampling depth is controlled, sample collection is convenient, fast;
2, material source is generally easily purchased, convenient processing, and cost is lower;
3, simple in structure, be convenient to dismounting, assembling and maintenance;
4, weight is less, is easy to carry, and rapid operation, saves time.
Accompanying drawing explanation
Fig. 1 is the structural representation of shallow water body bottom mud column-shaped sampling apparatus of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, shallow water body bottom mud column-shaped sampling apparatus of the present invention is described in further detail.
As shown in the figure, bottom mud column-shaped sampling apparatus of the present invention, is total to three parts by inserted link 1 and osculum 2, hollow cylindrical sampling pipe 3 and back cover part 4 and forms.The direct bonding sampling pipe 3 top closure weighing apparatuses of inserted link 1 cover, and can be regulated according to the degree of depth of sampled point water body actual grade and required bed mud sample, as can be by inserting or bind the mode extending lengths such as rod, rod, pipe.Draining (gas) hole 2 is the apertures outside the hollow top of UNICOM's sampling pipe and sampling pipe, when sampling pipe 3 deeply approaches bed mud surface downwards in water body, due to draining (gas) hole and sampling pipe perforation, so be full of water in sampling pipe 3, when sampling pipe 3 is inserted downwards dark time by bed mud surface, the water in sampling pipe 32 is discharged from draining (gas) hole due to the pressure of bed mud.Hollow cylindrical sampling pipe 3 is organic glass pipe or hard plastic tube, and its length determines by conventional bed mud sampling depth, by the back cover part 4 of bottom, is divided into coaxial two parts up and down, and the bed mud sample of getting is positioned at top section.Machine glass round tube or hard plastic tube that connecting rod bonding place 5 is a bit larger tham sampling pipe by four diameters form, and its arc length is less than 1/3rd sampling pipe external diameter circumferences, by seccotine or screw, fixes, and connecting rod 6 is connected up and down with stopple coupon 3.Connecting rod 6 can by stopple coupon Shang Xia 3 the concentricity axle of two parts connect, guarantee that stopple coupon 3 can not bend inserting upper and lower two parts when dark downwards, the problems such as disengaging.The fixation point of one of them elastic wire 8, other one is embedded with roller bearing 9 in the middle of bar, to help, guarantees that stopple coupon 3 reduces resistance being deep into after desired depth when rope is in sealing back cover part 4.Back cover part 4 is comprised of elastic caoutchouc flexible pipe 7, elastic wire 8, roller bearing 9, rope 10 etc., is that stopple coupon 3 guarantees the device that bottom is gas-tight after being deep into desired depth.The internal diameter of elastic caoutchouc flexible pipe 7 under state of nature is a bit larger tham stopple coupon 3 internal diameters, and length is greater than stopple coupon, and Shang Xia 3 two parts fractures space, and two ends are bonding or be bundled near outside surface stopple coupon 3 breaking parts.When stopple coupon 3 is being deep into after desired depth, elastic caoutchouc flexible pipe 7 is tied tight to being close to sealing completely by elastic wire 8, to guarantee that upper end bed mud is unlikely to drop, come off because of Action of Gravity Field when upwards promoting; When elastic wire 8 returns to ortho states, rely on again self elasticity to return to ortho states, upper end bed mud drops, comes off because of Action of Gravity Field, obtains required sample.Elastic wire 8 one end lie in the middle of a lateral connector bar 6, be wound around elastic caoutchouc flexible pipe and after 7 one weeks, connect rope 10, when rope 10 is walked around roller bearing 9 and upwards promoted, elastic wire 8 is tied elastic caoutchouc flexible pipe 7 tight to being close to sealing completely, and when rope 10 loosens, elastic wire 8 relies on self elasticity to return to ortho states.Roller bearing 9 is embedded in the middle of the connecting link 6 of elastic wire 8 stiff end opposite sides, reduces resistance while striving for making progress rope.10 1 sections of ropes connect elastic wires 8, and the other end extends upward, and upwards promote the elastic wire 8 of tying tight then tie that to demonstrate,prove bottom gas-tight for elastic caoutchouc flexible pipe 7 tight by sampling personnel.
Use institute's invention product to get bed mud at coastal cultivating pool, in sampling process, sample collector stands on sampling boat or bank, pond, first guarantee elastic wire 8 in the raw, holding inserted link 1 inserts dark by sampling pipe 3 downwards, when bed mud is surperficial on earth, go into overdrive to the sampling depth of expection, the bed mud sample of required collection has just entered in sampling pipe 3, vacate and upwards draw high on the other hand rope 10 to elastic wire 8 and elastic caoutchouc flexible pipe 7 and close, the rope 10 of extended state is now fixed on inserted link 1, so just bed mud sample is sealed in to sampling pipe 3 inside.Inserted link 1 is upwards lifted out to the water surface, stopple coupon 3 is vertically placed on the pallet of horizontal positioned, unclamp rope 10,4 envelope experiment bottoms minute return to the open state before sampling, by self gravitation, effect is vertically placed on pallet bed mud, choose and be applicable to position Sample storage, all the other bed muds discard, and complete whole bottom mud column-shaped sample collection processes.
