Multi-point water sample automatic acquisition device carried by unmanned ship and method

Abstract

The invention provides a multi-point water sample automatic acquisition device carried by an unmanned ship. The multi-point water sample automatic acquisition device comprises a water sampling control module, a water inflow device, a water storage device and a transmission device. The water inflow device comprises a water suction pump, a water suction pipe for water suction and a connecting pipe for connecting the water suction pump with the water storage device. The water storage device comprises a tray, a supporting rod, a water sampling bottle frame, water sampling bottles and a cover plate. The water sampling bottle frame is fixed above the tray through the supporting rod, and the transmission device can drive the water sampling bottle frame to rotate around the supporting rod. A circle of water sampling bottle clamping grooves is formed in the water sampling bottle frame, and one water sampling bottle is clamped and fixed into each water sampling bottle clamping groove. The cover plate capable of covering the water sampling bottle frame is installed above the water sampling bottle frame, a water pipe joint communicated with the connecting pipe is arranged on the cover plate, and the water sampling control module is used for controlling the rotating angle of the water sampling bottle frame and the starting and stopping time of the water suction pump. Multi-point water sample acquisition can be achieved, manual work can be replaced, precision control can be achieved during multi-point acquisition, efficiency is high, and installation and use are both convenient.

Description

technical field [0001] The invention relates to the technical field of water sample collection, in particular to a multi-point water sample automatic collection device and method carried by an unmanned ship. Background technique [0002] Obtaining representative and effective samples from the water environment is the basic work of water environment analysis and monitoring. In addition to some items (such as water temperature, dissolved oxygen, conductivity, etc.) In order to ensure the representativeness of collected water samples and avoid using near-shore water bodies (affected by the surrounding environment and human activities) to affect the composition of water bodies, the location of water collection is required to be as far away from the shore as possible, and reasonable layout of sampling points should be set in the entire water area. However, when carrying out water environment monitoring work in uninhabited areas or water bodies without boats, because it is imposs...

Problems solved by technology

However, when carrying out water environment monitoring work in uninhabited areas or water bodies without boats, because it is impossible to go deep into the center of the water area, the current practice is to only collect near-shore water bodies, and use the near-shore water sample analysis data as the basis for judging the water quality of the entire water area. data, this will definitely affect the accuracy of the judgment
