Abstract
The utility model discloses a small gravity sediment column type sampling device, which comprises a drill bit, a column type sampling pipe, a gravity lifting pipe and a lifting ring. The drill bit is provided with a petal for preventing back flow. Both ends of the sampling pipe are respectively in sealing connection with the drill bit and the gravity lifting pipe. The middle part of the gravity lifting pipe is welded with a conical weight, and the pipe wall on the lower part of the gravity lifting pipe is provided with a through hole. The lifting ring is fixed on the upper part of the gravity lifting pipe. The utility model which has the advantages of simple structure, low cost, convenient use, adjustable weight, and high sampling rate is suitable for the column type sampling of multi-type sediments, such as mud type, sand and mud type, sand type, etc. The sediment interface turbulence of the sampling sample is small, and the device can proceed with completely manual sampling operation without the auxiliary machinery power and the adaptability is greatly increased.
Description
Technical field
But the utility model relates to the little gravity sedimentation thing columnar sampler that waters sediment ecologic environment inquiry agencies such as a kind of widespread use Yu Haiyang, lake, river and pond need.
Background technology
Waters sediment ecologic environment investigation such as ocean, lake, river and pond often need sediment is carried out the column sampling.Currently used sediment column-shaped sampling apparatus mainly contains gravity sampling thief, gravity piston sampling thief and vibration type piston sampling thief.These several sampling apparatus complex structures, build is big and heavy, needs special electric winch and boom hoisting, generally can only use on the oceanographic research ship of specialty, and therefore, its manufacturing cost and use cost are all higher.In addition, carry out sediment column when sampling carrying out immediate offshore area, lake, river and pond etc., generally be difficult to be equipped with electric winch and boom hoisting, its use is restricted.
The utility model content
It is a kind of simple in structure, with low cost, easy to use that the purpose of this utility model is to provide, the little gravity sedimentation thing columnar sampler that weight is adjustable.
The purpose of this utility model can realize by following technical measures: comprise drill bit, column sampling pipe, gravity carry the pipe and suspension ring, described drill bit is provided with and prevents the petal that flows backwards, be tightly connected respectively drill bit and gravity of described sampling pipe two ends is carried pipe, gravity is carried the pipe middle part and is welded with the taper weight, the bottom tube wall that gravity is carried pipe is provided with through hole, and suspension ring are fixed in the top that gravity is carried pipe.
Gravity described in the utility model is carried and is socketed with balancing weight on the pipe, and balancing weight places on the taper weight.
Gravity described in the utility model is carried pipe top and is fixed with the empennage that is used for balance.
Suspension ring described in the utility model are the U-shaped suspension ring, hinged two cover plates that place gravity to put forward the pipe upper port on arm.
The utility model is simple in structure, with low cost, easy to use, weight is adjustable, is suitable for the sedimental column sampling of polytypes such as shale, argillo and chiltern, the sampling rate height, the sediment interfacial disturbance of institute's sample thief is little, and can carry out total man worker's sampling operation under no Aided Machine dynamic condition, its applicability improves greatly.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model comprises that drill bit 1, column sampling pipe 2, gravity carries pipe 3 and suspension ring 4, and drill bit is made by stainless steel material, and interior welds petal 5 can prevent in lifting process that like this columnar deposition matter sample of adopting from flowing backwards away.Column sampling pipe 2 is made by stainless steel material, and all there is connecting thread at two ends, and drill bit 1 is connected the lower end of column sampling pipe 2, and the upper end of column sampling pipe 2 is carried pipe 3 through attaching nut 6 with gravity and is connected.Gravity is carried pipe and is made by stainless steel material, gravity carry pipe on the lower side section be welded with by the plumbous weight 7 of the taper of stainless steel material embedding, to increase the weight of sampling thief; Can carry suit balancing weight 8 on the pipe at gravity according to needs in addition, balancing weight is made by the plumbous weight of stainless steel material embedding, and balancing weight 8 can place on the taper weight 7, can more increase sampling thief weight like this; Carrying pipe 3 nearly sampling pipe ends at gravity has an apopore 9, enters gravity when discharging sampling and carries water in the pipe, and gravity is carried the pipe end and is drilled with four screws, is used to connect U-shaped suspension ring 4 and empennage 11.Hinged two cover plates 12 that place gravity to put forward the pipe upper port on the arm of U-shaped suspension ring, under sampling thief, when down-sampled, can make current carry pipe, when sampling thief promotes by sampling pipe and gravity, can prevent that again current from entering in the sampling pipe, adopting cylindrical sample is exerted an influence.Empennage has four, plays equilibrium activity in sampling process, to prevent that sampling thief tilts in the sampling process.The sample of adopting is inserted in the sampling pipe by the sample poker and extrudes cylindrical sample, and the compressing tablet diameter on sample poker top is slightly less than and sample tube inner diameter.
Claims (4)
