Abstract

The invention provides an in-situ water collecting device and method for an underwater oil water sample to solve the problem that the normal use and a measured result are affected by defects on the aspect of an operating container cover switch existing in the prior art. The in-situ water collecting device for the underwater oil water sample comprises a container cover, a double-spring assembly and an electric magnet. When the in-situ water collecting device for the underwater oil water sample is used, a mechanism for opening the container cover is started through a control button of a deck unit after the device reaches a set depth. After an underwater electric control part receives an instruction, a power source of the electric magnet is started, a tensile force is provided by the electric magnet to pull a locking pin and generate displacement, a cover opening lever is pulled by a cover opening spring to break away from a locking position to move, water is collected through opening the container cover under the action of the lever, the electric magnet is started to act to close the container cover after the water is collected, an underwater part is lifted to a deck by pulling a rope, a container is taken out, and a water sample in the container is stored for analysis and research. The in-situ water collecting device has the advantages of simpliness and reliability in operation, accurate and reliable actions for opening and closing the cover, accurate measured result and the like.

Description

technical field [0001] The invention belongs to the technical field of marine environment investigation, and specifically relates to an in-situ water collection device and collection method for underwater oily water samples. Background technique [0002] With the development of the ocean, environmental pollution is also becoming more and more serious. Among them, marine oil pollution has attracted widespread attention. Oil pollutes the ocean and brings great harm to the marine ecological environment. First and foremost are plankton at the bottom of the marine food chain, which accounts for about 95 per cent of the total ocean productivity. Oil dissolved in seawater is even more harmful to fish. It damages various tissues and organs of fish. Oil is obviously harmful to fish eggs and larvae. One liter of seawater contains 0.1 mg of oil, which will cause all the hatched young fish to be deformed, and they can only survive for 1 to 2 days. Benthic animals living on the sea...
