Problems solved by technology
Most of the existing water body sampling equipment is to manually put the water sampling device down from the water area, let it stand for a period of time, and then extract it. The depth control deviation of the water sampling device is large, and it cannot Make sure that the water samples taken are from the same location and at different depths, so the water body detection results will be biased
Sampling personnel enter the water area for manual sampling, but when the sampling water area is too wide and dangerous, and the working environment is very dangerous, this method of relying on the mother ship and manual sampling will be very difficult, and the efficiency of manual sampling is low, the operation is cumbersome, and the work intensity Big

The invention provides a water body sampling device. The water body sampling device comprises a fixed cover, a shell fixed with the fixed cover and a water sampling mechanism arranged below the shell,a driving mechanism for controlling the water sampling mechanism to move up and down is arranged at the top of the shell and comprises a rotating shaft, fixing blocks fixed to the two ends of the rotating shaft correspondingly and a first driving motor, and a reel sleeves the rotating shaft. A connecting rope connected with the water sampling mechanism is wound on the reel, and the water samplingmechanism comprises a connecting frame, a guide sleeve, a water storage device sleeving the guide sleeve and a driving assembly used for driving the water storage device to move up and down. A through hole is formed at the position, corresponding to the connecting frame, of the shell, and the connecting frame comprises a connecting cap connected with the connecting rope, a connecting rod arrangedat the bottom of the connecting cap and a fixing plate connected with the bottom end of the connecting rod. The water body sampling device is accurate in sampling precision, high in sampling efficiency and wide in application range, and is convenient to operate.
Description
technical field [0001] The invention specifically relates to a water body sampling device. Background technique [0002] Water body sampling is a job that cannot be underestimated in water quality analysis and monitoring, and the selection and improvement of water body sampling technology play a vital role in the representativeness, validity and accuracy of water sampling. Most of the existing water body sampling equipment is to manually put the water sampling device down from the water area, let it stand for a period of time, and then extract it. The depth control deviation of the water sampling device is large, and it cannot Make sure that the water samples taken are from the same location and at different depths, so the water body detection results will be biased. Sampling personnel enter the water area for manual sampling, but when the sampling water area is too wide and dangerous, and the working environment is very dangerous, this method of relying on the mother ship ...
