Abstract
The invention relates to an interference free fidelity sampler used in a deep sea near bottom surface water body, which comprises a frame, a sampling cell, a guide board, a micro controller and a trigger. The invention adopts the guide board to enable the orientation of the sampling drum before sampling through the sampler to be constant with the flow direction of the sea water; the trigger is arranged behind the sampler, thereby preventing the trigger from exciting the deep sea sediments to cause pollution when arriving the bottom, and achieving the deep sea water body interference free sampling; and an energy accumulator which is pre-filled with pressure is used as a pressure compensator, thereby achieving the pressure sampling of water body.
Description
Technical field
The present invention relates to a kind of deep-sea water body sampler, be specifically related to surface water sampler at the bottom of a kind of deep sea offshore.
Background technology
Existing deep-sea water body sampler can only be carried out the water body sampling usually in the space, deep-sea, can not take a sample to surface water at the bottom of the coastal waters, deep-sea (depth of water is greater than 3000 meters), more can not realize the serial sampling to the differing heights surface water.The surface water sampler is abroad arranged, but take a sample the depth of water, be generally used for the surface water sampling in lake and shallow sea, and can not realize the no disturbance sampling of surface water less than 1000 meters.
Summary of the invention
In order to realize the deep sea offshore surface water body disturbance-free fidelity sampling, special proposition the present invention.
The technical solution adopted for the present invention to solve the technical problems is:
The deep sea offshore surface water body disturbance-free fidelity sampler, comprise framework, be separately installed with sampling unit and fair water fin in the both sides of framework, angle between sampling unit and the fair water fin is 180 °, top at framework is provided with microcontroller, one end of microcontroller is drawn the control line of the high pressure sea water solenoid valve of sampling unit, and the other end connects the trigger of sampler.Trigger is installed on the framework, is positioned at the same side with fair water fin, and trigger position in vertical direction is lower than the bottom of framework, guaranteeing sampler in the process of transferring, trigger than framework first the end.
Sampling unit is made of sampling cylinder, filtrator, high pressure sea water solenoid valve and accumulator, one end of sampling cylinder connects the high pressure sea water solenoid valve, the other end connects accumulator, filtrator is installed in the inlet of high pressure sea water solenoid valve, and the upright position of sampling unit on framework can be regulated arbitrarily as requested.
A plurality of sampling units can be installed to realize the sampling of differing heights water body on framework.
The present invention is by the design fair water fin, guaranteed sampler before sampling sampling cylinder towards consistent with the flow direction of seawater, by trigger being placed on the rear of sampler, evoke abyssal sediment when having avoided trigger the end sampling waters is polluted, realized that the deep-sea water body does not have the disturbance sampling; The accumulator of employing preliminary filling pressure has been realized the gastight sampling of water body as pressure compensator.
