Abstract

The invention relates to a middle and lower layer water sample sampler which comprises a raising rope, a hollow sampling cylinder and a cylinder bottom. A circular hole is formed in the cylinder bottom, and the position of the center of the circle of the circular hole is the same as that of the center of the circle of the cylinder bottom; a T-shaped blocking part is arranged at the circular hole of the cylinder bottom and comprises a circular block piece and a cylindrical protruding part fixedly arranged on the lower portion of the circular block piece, the diameter of the cross section of the cylindrical protruding part is smaller than that of the circular hole, the diameter of the circular block piece is larger than that of the circular hole, the diameter of the circular block piece is smaller than that of the cylinder bottom, a long-strip-shaped limiting baffle is arranged on the upper portion of the circular block piece and is parallel to the plane where the circular block piece is located, and the two ends of the limiting baffle are fixed on the inner wall of the hollow sampling cylinder. Compared with the prior art, the middle and lower layer water sample sampler has the advantages of being capable of conveniently and rapidly collecting water samples of the middle and lower layer, simple in structure and accurate and reliable in sampled water samples.

Description

technical field

[0001] The invention belongs to the field of water quality sampling instruments, and in particular relates to a water sampler for middle and lower layers, which can be applied to collect water samples for middle and lower layers. Background technique

[0002] Emergency response and follow-up environmental monitoring and evaluation after oil spill accidents are necessary measures to grasp the environmental hazards of oil spill. The current environmental monitoring of the impact of oil spill accidents is mainly based on traditional marine environmental monitoring technical means, and the method system designed according to the needs of conventional environmental monitoring has many shortcomings in dealing with oil spill pollution, especially in seawater oil sampling levels. In traditional monitoring, most petroleum samples can only collect surface samples (0.5-1m underwater). However, in actual oil spill accidents, due to the use of oil dispersants, a large am...
