Embodiment
Describe performance of the present utility model in detail below in conjunction with accompanying drawing.
Consult accompanying drawing known: a kind of standardization rivers and canals ice sheet sample extraction device, it comprises gets ice auger bar A, gets ice sleeve C and flexible handle B.
Get ice auger bar A and comprise handle retainer ring A4, handle retainer ring A4 lower end is connected with drill bit connecting rod A3; Drill bit connecting rod A3 lower end is got ice auger head A1 with pinnacle taper shape down and is connected; Getting on ice auger head A1 upper surface has activity to hold in the palm ice production apparatus A2.
Get ice sleeve C and comprise cylindrical empty cylinder C4, cylindrical empty cylinder C4 is provided with two symmetrical handle support hole C5; On cylindrical empty cylinder C4, be penetrated with fixed handle C3; Outside, cylindrical empty cylinder C4 middle part is provided with load-bearing ring plate C2; Cylindrical empty cylinder C4 lower end is connected with circular saw C1.
Flexible handle B is through handle retainer ring A4 and handle support hole C5.
Preferably, getting ice auger head A1 outside is provided with spiral and helps bar.Movable holder ice production apparatus A2 comprises and is positioned at the blade rotation bearing A22 getting on ice auger head A1 upper surface; The upper fixed blade rotation axis A23 of blade rotation bearing A22, is connected with movable holder ice blade A21 on blade rotation axle A23.
Preferably, load-bearing ring plate C2 interval is furnished with four, and load-bearing ring plate C2 is sector structure.Movable holder ice production apparatus A2 has spaced apart four groups.
Wherein, get ice auger head A1 in order to drill through holder ice hole in cylindrical ice body center of a sample, the spiral of getting ice auger head A1 outside helps bar to help ice bits to be transported in sleeve, prevents that it from assembling in the extruding of drill bit leading portion; Drill bit connecting rod A3, in order to connect drill bit and handle retainer ring, ring lower edge to bit point of the drill distance is greater than the distance of outer handle support hole C5 lower edge to standard stack shell C4 lower edge, reduces device and ice face contact area in the time starting to hole, and increases the pressure producing from focusing on bit point of the drill.
When the present invention works, under the pressure providing in device deadweight, with fixed handle C3, and flexible handle B is as the power arm of device rotation, samples on ice sheet by circumgyration incision.Get ice auger bar A and get ice sleeve C and pierce successively ice sheet, and link together by flexible handle B, whole device runs through ice sheet downwards, until load-bearing ring plate C2 contact ice face.Load-bearing ring plate C2 props up device really, and movable holder ice blade A2 is launched into almost plane in the water under ice face under the effect of gravity and centrifugal force.Mention whole device, the ice sample of getting this under the support of activity holder ice blade A2, ice face is proposed.
Summarizing the ice sheet sample that described employing the utility model obtains is the standard cylinder of central zone standard circular hole; Circular hole and right cylinder radius can need to customize according to sampling, have ensured that the ice sheet sample that extract in different personnel, different time and place has comparability.Get ice hole and ice body size is basically identical, meeting on the basis of sample study needs, reduced to greatest extent the destruction to ice sheet.The utility model adopts circular saw drill hole sampling on ice sheet, has simple labour-saving feature.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also design some changes and retouching, these improvements and modifications also should be considered as protection scope of the present invention.
