DEVICE FOR CONTINUOUSLY SAMPLING DEEP SEA SURFACE WATER

摘要

Disclosed is a device for continuously sampling deep sea surface water. The device comprises a bracket liftable vertically along a side of a vessel, wherein a sampling tube for sampling the surface water by sucking and a hydraulic cylinder for driving the bracket to rise and fall to make the sampling tube reach the surface water are fixed on the bracket; and the bracket is provided with a buffer mechanism for preventing damage to the sampling tube due to continuous resistance generated by seawater when a hull is travelling. The arrangement of a depth sensor, a controller and the hydraulic cylinder can not only effectively ensure the accurate acquiring of the surface water, but also realize continuous collection during the voyage of a research vessel. The buffer mechanism not only effectively prevents axial and radial damage to the sampling tube due to the action of continuous flow resistance on the sampling tube, but also achieve the alleviation of the resistance, thereby prolonging the service life of the sampling device. By means of an automated control mode, the aim of automated surface water collection is realized.
