Problems solved by technology

[0004] But in actual use, because people sometimes need to take samples in the middle of the river to achieve the purpose of precision, but it is not easy to control the depth by means of buckets, and the dark current in the depths of the river is surging, it is easy to wash the bucket away , so we urgently need a water sample extraction device with strong stability

Embodiment 1

[0029] refer to Figure 1-5 , a water sample extraction device based on river ecological detection, comprising a floating plate 6, the top outer wall of the floating plate 6 is provided with a mounting hole, the inner wall of the mounting hole is fixed with a fixed box 3 by bolts, and the inner wall of the fixed box 3 is fixed with a bolt. The mounting plate has a fixing hole on the outer wall of one side of the mounting plate, and the inner wall of the fixing hole is fixed with a double-axis motor 8 by bolts. The output shaft of the double-axis motor 8 is connected with a third rotating rod through a coupling, and one end of the third rotating rod The first runner 2 is fixed by bolts, the top outer wall of the floating plate 6 is provided with a transmission mechanism, the inner wall of the installation hole is fixed with the installation box 1 by bolts, and the second motor 15 is fixed on the inner wall of the installation box 1 by bolts. The output shaft of 15 is connected ...

Embodiment 2

[0039] refer to Image 6 , a water sample extraction device based on river ecological detection. Compared with Embodiment 1, this embodiment also includes a drag-reducing block 26 fixed on the bottom outer wall of the floating plate 6 by bolts.

[0040] During use, the floating plate 6 can be made more stable when moving on the river surface by the drag reducing block 26, and can be guaranteed to be more stable when the floating plate 6 moves at the same time, reducing the resistance of the river water to the floating plate 6 when the floating plate 6 moves.

Abstract

The invention belongs to the technical field of water sample extraction, particularly relates to a water sample extraction device based on river channel ecological detection, and aims to solve problems that a depth of an existing water sample extraction device is not easy to control in a bucket mode, and a bucket is easy to wash away due to the fact that underflow surges in the deep of a river. The device comprises a floating plate. A mounting hole is formed in the outer wall of the top of the floating plate, a fixing box is fixed to the inner wall of the mounting hole through bolts, a mounting plate is fixed to the inner wall of the fixing box through the bolts, a fixing hole is formed in the outer wall of one side of the mounting plate, and a double-shaft motor is fixed to the inner wallof the fixing hole through th ebolts; and an output shaft of the double-shaft motor is connected with a third rotating rod through a coupler, and a first rotating wheel is fixed to one end of the third rotating rod through the bolt. The weight of a weight hammer is large, the floating plate can be fixed, meanwhile, a sampling head can be stabilized in river water with a certain depth, and therefore the sampling head can extract river water with a precise depth.

Description

technical field [0001] The invention relates to the technical field of water sample extraction, in particular to a water sample extraction device based on river ecological detection. Background technique [0002] Water samples can be divided into instantaneous water samples and mixed water samples in terms of sampling time; in terms of sampling concentration, they can be divided into surface water samples, middle water samples and bottom water samples; in terms of test items, they can be divided into water quality water samples samples and biological water samples. The representativeness of water samples is the prerequisite for the accuracy of analysis and testing and the reliability of evaluation conclusions. In order to ensure the representativeness of water samples, it is necessary to select representative monitoring sections or monitoring points, adopt standardized sampling methods, and Collect samples within the system, and stabilize the collected water samples in a ti...
