Description

Technical Field

[0001] The utility model relates to the technical field of water environment monitoring, in particular to an automatic sampling device for monitoring water environment quality. Background Art

[0002] Water environment monitoring takes the water environment as the object, and uses physical, chemical and biological technical means to conduct qualitative, quantitative and systematic comprehensive analysis of the pollutants and their related components in it, in order to explore and study the changing patterns of water environment quality.

[0003] In the monitoring process, sampling of water quality is an essential detection step. The common water environment quality detection is to install the detection device on a floating plate to facilitate the extraction of water samples. However, the position of the floating plate is often fixed at a certain position on the water surface and cannot move autonomously. Therefore, when sampling the water surface in different areas, the floating plate needs to be moved manually, which is relatively cumbersome and cannot realize automated water sample collection.

[0006] Preferably, the driving assembly includes a steering groove, which is opened at the center position of the bottom of the floating plate. The rotating plate is rotatably connected to the bottom of the steering groove. A worm gear is fixed to the upper end of the rotating plate. A worm is rotatably connected in the steering groove and located at the periphery of the worm gear. The worm wheel and the worm gear are meshing.

[0007] Preferably, a servo motor is fixed on the side wall of the steering groove and at a position corresponding to the worm, and the output end of the servo motor is fixed to the end of the worm.

[0008] Preferably, a positioner is fixed to the upper end of the detection box, and a solar power generation panel is fixed to the side wall of the detection box.

[0009] Preferably, a winch is fixed to the upper end of the floating plate, and an anchor rope is wound around the winch, and an anchor plate is fixed to the end of the anchor rope.

[0010] Compared with the prior art, the utility model has the following beneficial technical effects: the rotation of the impeller can make the floating plate move autonomously on the water surface, and the rotation of the rotating plate can change its movement direction, thereby realizing automatic sampling and detection of different areas, and the operation is simpler.
