Embodiment
Do to illustrate into-step to the utility model below in conjunction with the drawings and specific embodiments, but not as to restriction of the present utility model.
See Fig. 1 and Fig. 2, a kind of detachable shallow-water deposit thing original position columnar samples sampling apparatus, the metal tube 3 comprising the afterburning handle 2 of upper end mouth of pipe band and the sampling pipe 9 be connected to below; The present embodiment preferable alloy pipe is the aluminium-alloy pipe of hollow, and metal tube 3 termination is provided with screw thread, and multistage metal tube 3 can be threaded connection with into length different arbitrarily, realizes needing the sampling of different water depth by regulating the total length of metal tube; Afterburning handle 2 is welded in the both sides, top being connected to uppermost one section of metal tube 3, for providing the lower shear force of sampling pipe 9 in sampling process, regulates plug 1, to control the water column pressure in sampling pipe 9 in the top mouth of pipe of metal tube 3 with pressure.The open top of metal tube 3 establishes pressure to regulate plug 1, and bottom opening is connected on connector 4, and sampling pipe 9 is the plexi-glass tubular of standard configuration, can also use pvc pipe or select metal tube, the convenient observation to collected specimens of plexi-glass tubular, and durable; Connector 4 is connected with sampling pipe 9 by butt junction 7; Described butt junction 7 is the uncovered cylindrical structures in bottom, and connector 4 is welded on the top of butt junction 7, and connector 4 top is provided with screw thread, is connected with metal tube 3 by screw thread; The centre of described top panel has a port 14 being undertaken sealing by retaining valve 6, described retaining valve 6 controls current and enters connector 4 from sampling pipe 9, water regulates plug 1 to discharge by retaining valve along metal tube 3 from pressure, retaining valve 6 keeps sampling pipe water channel unobstructed, extra pressure can not be applied to sediment, ensure not produce sediment in sampling process significantly to corrode and disturbance; Flange 8 is set in the bottom of described butt junction 7, is lined with elastic adapter ring 10 between described lower flange 8 and butt junction 7, and described lower flange 8 is connected by coupling bolt 5 with top cover, and the edge symmetry of top cover establishes bolt hole.The both ends open of described sampling pipe 9, its top is passed in the preformed hole at lower flange and elastic adapter ring 10 center, stretch in butt junction, the internal diameter of elastic adapter ring 10 and lower flange 8 and the external diameter of sampling pipe 9 adapt, after coupling bolt 5 is fastening, elastic adapter ring 10 is out of shape, and carries out elasticity extruding realize elasticity connection to sampling pipe 9; As in Fig. 1, the direction of arrow is water (flow) direction, and described metal tube 3, connector 4, butt junction 7 are communicated with formation water stream channel successively with the internal cavities of sampling pipe 9.
In the later stage sealing of sampling pipe 9, its port cap gland bonnet 15, be hard plastic lid, gland bonnet 15 wild card has clasp 11, and clasp 11 is annular sheet metal, and one end is provided with bolt hole, and the other end is fastening bolt 12.Establish sealing gasket 12 between the mouth of pipe of gland bonnet 15 and sampling pipe 9, preferred sealing gasket 12 is rubber gasket.Sealing gasket 12 pads inside gland bonnet 15, and clasp 11 after touch, screws with bolt 13 by sampling pipe 9 and sealing gasket joining, can prevent the spilling of S & W sample in sampling pipe after sealing gasket 12 stress deformation.
Elastic adapter ring 10 can be rubber 0 type sealing ring or plastic cement material circle, by the fastening elasticity of compression abutment ring 10 of bolt 5, elasticity of compression abutment ring 10 is out of shape rear clamping sampling pipe 9, makes sampling pipe 9 be fixedly connected on coupling assembling bottom, after unclamping coupling bolt 5, sampling pipe 9 can conveniently take out.
Principle of work of the present utility model and method of operating as follows:
After assembling equipment according to above-mentioned annexation, manpower is relied on vertically to be inserted in shallow-water deposit thing by sampling pipe 9 by afterburning assembly.In sampling process, the water entering sampling pipe 9 top is flowed into successively by retaining valve 6 and enters in connector 4 and metal tube 3, run up to a certain amount of after discharge from the top mouth of pipe of metal tube 3, the arranging of retaining valve 6 can ensure that sampling pipe has a unobstructed water channel, extra pressure can not be applied to sediment, sediment is not produced and corrode and disturbance, keep the virgin state of columnar deposit sample in metal tube 3.Namely sampling pipe 9 applies pressure no longer downwards after being inserted into regulation sampling depth, and retaining valve 6 relies on deadweight to fall after rise, cover on the top mouth of pipe of sampling pipe 9, the pressure tightening the metal tube 3 top mouth of pipe regulates plug 1, seals device interior space, increases the leakproofness of harvester.Hold afterburning handle 2, vertically pull up whole harvester and complete sampling.Under hydraulic pressure effect, above carry sediment post in process and there will not be landing phenomenon; Cover tightly bottom sampling pipe with elastic adapter ring 10 before the bottommost of sampling pipe 9 leaves the water surface, and then leave the water whole for harvester, the clasp 11 bottom fastening sampling pipe 9, guarantee that sampling pipe 9 bottom does not have water to ooze out.Then the pressure unclamping top keep the prerequisite of vertical state at harvester under regulates plug 1 and coupling bolt 5, is carefully taken out from butt junction 7 by sampling pipe 9, covers the gland bonnet 15 of the top mouth of pipe, and the clasp 11 at fastening two ends.
In whole process, sampling pipe 9 remains vertical state, and top, guarantees that sampling pipe 9 upper end does not have water to overflow all the time upward, thus obtains the in-situ deposition thing cylindrical sample with actual deposition thing state consistency.
Above-described embodiment, the just one of the utility model more preferably embodiment, the usual change that those skilled in the art carries out within the scope of technical solutions of the utility model and replacing all should be included in protection domain of the present utility model.
