Bottom sampler and bottom sampling method

Abstract

The invention discloses a bottom sampler, comprising a water storage tank, wherein a rubber hole is set on a top of the water storage tank; a fixed rod is set in the rubber hole; a connection plate isset on the top of the fixed rod; resisting pillars are set at a bottom of the connection plate; the tops of the resisting pillars are fixedly connected with the connection plate; a suction plate is set at the bottom of the fixed rod; fixed blocks are set at two sides of the water storage tank; a control frame is set on the tops of the fixed blocks; the bottom of the control frame is fixedly connected with the fixed blocks; a positioning rod is set on the top of the control frame; a threaded hole is set at one side of the positioning rod; and sliding slots are set at two sides of the water storage tank. According to the bottom sampler, through setting of a clamp rod and a handle bolt, when the bottom sampler enters into water, jacking pillars do not slide in the sliding slots, so the waterstorage tank does not collect surface layer water, a worker can obtain bottom water samples conveniently, bottom sampling quality and efficiency of the worker are improved, and time and labor are reduced.

Description

technical field [0001] The invention relates to the technical field of exploration and development devices such as marine survey ships, in particular to a bottom sampler and method. Background technique [0002] Water is an important resource for human beings. Whether it is the development and utilization of water resources or the control of water pollution, water sample detection is an extremely important basic content. The quality of the collected samples is the basis for accurate, scientific and reasonable environmental protection monitoring and analysis The premise is that with the development of time, people urgently need to develop and utilize water resources and pay more and more attention to environmental protection, which also makes the detection of water samples more and more important. It is not only necessary to detect the water meter but also the water quality at the bottom. This requires the bottom water sampler to take out the bottom water. However, when the e...

[0002] Water is an important resource for human beings. Whether it is the development and utilization of water resources or the control of water pollution, water sample detection is an extremely important basic content. The quality of the collected samples is the basis for accurate, scientific and reasonable environmental protection monitoring and analysis The premise is that with the development of time, people urgently need to develop and utilize water resources and pay more and more attention to environmental protection, which also makes the detection of water samples more and more important. It is not only necessary to detect the water meter but also the water quality at the bottom. This requires the bottom water sampler to take out the bottom water. However, when the existing bottom sampler enters the water, it is easy to mix with the surface water or the bottom sampler is originally a closed vacuum structure. It is difficult to bring the sampler into the bottom of the water due to the buoyancy of the water, and it is difficult to open the sampler and put the bottom water into the sampler due to the pressure at the bottom, which makes bottom sampling difficult, inaccurate and inconvenient to work The personnel obtains the bottom water sample, causes the efficiency of bottom sampling to be low, therefore, a kind of bottom sampler and method that can sampling efficiency height, sampling is accurate, time-saving and labor-saving are urgently needed on the market
