Specific embodiment
Presently preferred embodiments of the present invention is described in detail below in conjunction with the accompanying drawings, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, apparent clearly defines so as to make to protection scope of the present invention.
Accompanying drawing 1 to 5 is referred to, the embodiment of the present invention includes：Expansion link, swingle 3, rotary apparatuss, change hands 9, joint company
Connect device 8, fixing device 6 and conic net 7.The expansion link includes the first expansion link 1 and the second expansion link 2.The rotary apparatuss
Including the first rotary apparatuss 4 and the second rotary apparatuss 5.Second expansion link 2 is provided with changes hands 9, and changes hands 9 and have three, with
Each expansion link is connected with the inner strands of swingle 3.Being changed hands for the first expansion link 1 of the control have on 9 corresponding conic net 7 and enter
The scale of water depth shows that the second expansion link 2 is fixed on hull by fixing device 6, and fixing device 6 includes stationary rope,
Second expansion link 2 is vertically fixed on into hull side.Second expansion link 2 passes through the phase of the second rotary apparatuss 5 with swingle 3
Connect, and swingle 3 can pass through the rotation of the second rotary apparatuss 5 or rotate around the second expansion link 5.The expansion link and swingle 3
Make for firm material, inner hollow, built-in twisted wire, and swingle 3 is connected with expansion link inside.The upper end of first expansion link 1 leads to

One rotary apparatuss 4 and joint connector 8 play fixation.The expansion link stretch mode is similar to fishing rod, and built-in twisted wire is used for
Control is flexible, wherein with 7 mouthfuls of subscript metric system scales of the first expansion link 1 being connected of conic net, minimum scale centimetre, the bottom of bar with
7 mouthfuls of diameter connecting places of conic net are tangent.
During sampling, first by conic net, 7 mouthfuls are connected and fix with 1 liang of lower extreme point of the first expansion link so that network interface place face
Coplanar with the place face of the first expansion link 1, now the first expansion link 1 is contraction-like under beginning state.Then second is stretched
Bar 2 is connected to hull side and fixed, startup ship, adjusts to sampling course, and the tail end of conic net 7 is first placed in water, adjusts
Section changes hands 9 so that the first expansion link 1 is extended so that 7 mouthfuls of conic net is entered in water, continues regulation and changes hands 9 to required sampling
Depth, stops changing hands, and starts ship to start navigation.Treat the required sampling time（Or water amount）Reach, stop navigation.Now adjust
Section changes hands 9 so that the first expansion link 1 shrinks, and 7 mouthfuls of conic net is moved upwards, and to cut out the water surface perpendicular to water surface direction.Treat whole
The equal water outlet of 7 mouthfuls of individual conic net, the first expansion link 1 are contracted to minimum position, and regulation changes hands 9 so that the second rotary apparatuss are towards net
Mouthful direction be rotated by 90 ° so that network interface is rotated to towards surface, and regulation changes hands 9 so that the second expansion link 2 is protruded upward, extremely
Collect Seedling bottle water outlet, can contact, stop the second expansion link 2 of elongation, now collect sample.Sample collection is finished, and starts ship, boat
Row stops electromotor to sampling location next time, shrinks the second expansion link 2, is put into the end of conic net 7, and regulation changes hands 9 so that
Second rotary apparatuss 5 be rotated down 90 degree it is vertical with the water surface to network interface, regulation change hands 9 so that the first expansion link 1 extends, network interface enters
Enter to required sampling depth in water body, start ship and sampled.So repeat to sampling to finish.
