Anti-interference collection equipment for bottom seawater

Abstract

The invention discloses anti-interference collection equipment for bottom seawater, and aims to provide anti-interference collection equipment for bottom seawater, which can ensure that collected seawater is the bottom seawater at the set depth and effectively solve the problem that the quality of the collected water sample is affected by a fact that a heavy hammer touching the bottom stimulates mud water. The anti-interference collection equipment comprises a water collector, a tow rope connected with the upper end of the water collector, and a triggering expansion type heavy hammer device, wherein a floating device is arranged on the tow rope; the floatage of the floating device is greater than the sum of the gravities of the water collector and the floating device and less than the sum of the gravities of the water collector, the floating device and the triggering expansion type heavy hammer device; the triggering expansion type heavy hammer device comprises a main supporting rod, a triggering expansion type buffering umbrella arranged on the main supporting rod, a triggering device and a main balance weight; the main balance weight is positioned below the triggering expansion type buffering umbrella.

Description

technical field [0001] The invention relates to a water collector, in particular to an anti-interference collection device for bottom seawater. Background technique [0002] In a large number of scientific research and marine environmental monitoring work, it is usually necessary to collect a certain amount (depending on project requirements) of bottom seawater for bottom water quality (including pH value, dissolved oxygen, phosphate, inorganic nitrogen, heavy metals, etc.) or Analysis of plankton (including zooplankton and phytoplankton), etc. Bottom seawater generally refers to seawater at a depth of 2 meters (or 0.5 meters from the seabed) (GB17378.3-2007 "Marine Monitoring Specification Part 3: Sample Collection, Storage and Transportation" stipulates that the maximum It is best to take the water layer 2 meters away from the seabed, and the distance from the bottom layer can be increased as appropriate in deep sea or strong wind and waves). [0003] The current bottom ...
