(42) the kind of drive is to be driven by screw rod (421).
10. a kind of automatic water sample acquisition method of underwater multidimensional, which is characterized in that use any one of -10 institute according to claim 1
A kind of underwater automatic water sample acquisition device of multidimensional stated carries out water sampling, and steps are as follows:
(a), which works as, needs to acquire one-dimensional water sample,
When acquiring the water sample of different depth on same vertical line, said inner tube (112) is connected to the outer tube (111) side wall length
The different location in direction, probe tube (11) obtains Vertical one dimensional target water sample at this time；
When acquiring the parallel water sample of same depth, at least two outer tubes (111) are arranged in parallel in the horizontal direction, said inner tube
(112) it is connected to same depth location on the outer tube (111) side wall, probe tube (11) obtains laterally one-dimensional target at this time
Water sample；
(b) is when needing to acquire two-dimentional water sample, and using outer tube described at least two (111), the outer tube (111) is put down in transverse direction
Row arrangement, said inner tube (112) are connected to different depth position on the outer tube (111) side wall, at this time probe tube (11)
The water sample of extraction is the water sample on cross section in transverse direction, obtains two dimension target water sample；
(c) is when needing to acquire three-dimensional water sample, i.e., along the water sample in each cross section of water (flow) direction when, use at least three outer tubes
(111), transversely first direction and lateral second direction are horizontally disposed respectively for the outer tube (111), the first direction and institute
Second direction intersection is stated, said inner tube (112) is connected to the different location in the outer tube (111) sidewall depth direction, this
When probe tube (11) water sample for extracting be water sample on the first direction and the second direction cross section, obtain three-dimensional mesh
Mark water sample；
(d) each sampling bottle (32) of be at least connected with one group described in probe tube (11), the power unit (41) passes through described
Gear unit (42) acts on the sampling bottle (32), carries out water sample extraction；
(e) water sample extracts, and water sample extracts the mistake for finishing and being transferred to sampling beaker (33) from the sampling bottle (32) with water sample
Cheng Zhong, the controller (4) control the triple valve (2), are opened according to water flow trend the triple valve (2)
It closes.
