Dissolved oxygen water sampling key device of unmanned surveying vessel

Abstract

The invention discloses a dissolved oxygen water sampling key device of an unmanned surveying vessel. The device comprises an automatic cruise controller, a single-chip microcomputer and a dissolved oxygen sample bottle; the output end of the automatic cruise controller is in wireless connection with the input end of the single-chip microcomputer. The output end of the single-chip microcomputer iselectrically connected with the input end of a multi-channel relay controller. The output end of the multi-path relay controller is electrically connected with a micro pneumatic electromagnetic valve; the input end of a pressure reducing valve is communicated with a micro carbon dioxide gas cylinder; the input end of the dissolved oxygen sample bottle is communicated with a pneumatic injector A and a pneumatic injector B, a three-way quick connector is communicated between the pneumatic injector A and the pneumatic injector B, and the output end of the three-way quick connector is communicated with the input end of the micro pneumatic electromagnetic valve. By using the miniature carbon dioxide gas cylinder and the micro pneumatic electromagnetic valve, the water sampling key device is simple in structure and light in weight, only the miniature pneumatic electromagnetic valve needs to be triggered, and power consumption is low.

Description

technical field [0001] The invention relates to the technical field of marine water body monitoring, in particular to a key device for collecting dissolved oxygen water by an unmanned survey ship. Background technique [0002] According to the different use functions and protection goals of sea areas, sea water quality is divided into four categories: the first category applies to marine fishery waters, marine nature reserves and rare and endangered marine life protection areas. The second category applies to aquaculture areas, bathing beaches, marine sports or entertainment areas where the human body is in direct contact with seawater, and industrial water areas directly related to human consumption. The third category applies to general industrial water areas and coastal scenic tourist areas. The fourth category applies to ocean port waters and ocean development operation areas. [0003] Dissolved oxygen is one of the main elements in marine water monitoring. At present,...

Problems solved by technology

[0003] Dissolved oxygen is one of the main elements in marine water monitoring. At present, although there are unmanned survey ships that can collect surface water samples, they are all routine water samples, and there is no dissolved oxygen water sample collection capability or no dissolved oxygen sample collection. related devices, and in the process of taking water samples by unmanned survey ships, fixed reagents should be injected into the water samples. synchronized take
