Embodiment 1
[0046] Description of structure and interrelationships:
[0047] Such as figure 1 A kind of underwater multi-dimensional automatic water sample collecting device shown, such as figure 2Shown is a schematic diagram of the unit structure of the present application, which includes a volumetric water sample extractor 32, a three-way valve 2 is an electromagnetic three-way valve, a stepping motor 411, a controller 4, a fixed frame 321, and the inner tube 112 is a sampling hose , the outer tube 111 is a stainless steel capillary tube, and the part directly connected between the extractor 32 and the sampling tube 11 is a stainless steel tube. Under the action of controlling the stepper motor and the electromagnetic three-way valve, the volumetric water sample extractors 32 can be arranged side by side at equal distances to simultaneously extract water samples at different depths and at different positions on the same cross-section, realizing underwater sampling by Automatic collec...
Embodiment 2
[0080] Such as Figure 4-7 As shown, when only one-dimensional sampling is required, in order to simplify the sampling work, you can use such as Figure 4-7 The handle sampler shown is designed for sampling, the extractors are arranged side by side in a straight line, the sampling stretch is controlled by the handle, and the extractor can be flexibly disassembled through the detachable fixed extractor holder.
Embodiment 3
[0082] Using the underwater multi-dimensional automatic water sample collection device provided in Example 1 to carry out the method embodiment steps of water sample collection are as follows:
[0083] 1. When sampling, set the three-dimensional coordinate system according to the direction of water flow, set the sampling starting point of the research object as the coordinate origin, and establish a three-dimensional coordinate system. The direction of water flow is the X axis, the water depth direction is the Z axis, and the direction perpendicular to the water flow is the Y axis. .
[0084] 2. When it is necessary to measure the Z direction of the one-dimensional coordinate scale, that is, when water samples of different depths along the vertical direction at a certain point in the vertical water flow direction, the stainless steel capillary is installed in the vertical depth direction, and the outlets of the extractors 32 arranged side by side The sampling hose connected to...
