Problems solved by technology

However, in actual oil spill accidents, due to the use of oil dispersants, a large amount of oil spilled settled into the middle and lower water bodies, which exceeded the sampling range of conventional petroleum samplers, resulting in a major flaw in the monitoring and evaluation of oil spill impacts.
[0003] The utility model patent with the application number 201520222142.2 discloses a "new deep positioning water sampling device", which includes a hollow cylindrical base, a hollow sampling cylinder, a top cover of the sampling cylinder, a handle and a drawstring, and a cylindrical base. The upper surface of the hollow sampling cylinder is fixed coaxially, and a spring is fixed in the center of the upper surface of the cylindrical base. The spring is connected to the center of the top cover of the sampling cylinder. On the top of the cylinder, a lifting rope is fixed at the center of the t

Embodiment 1

[0022] Such as Figure 1-Figure 3 As shown, a water sampling device for middle and lower layers comprises a lifting rope 1, a hollow sampling cylinder 2 and a cylinder bottom 3, the lifting rope 1 is suspended in the hole at the upper end of the hollow sampling cylinder 2, and the hollow sampling cylinder The body is cylindrical, and the bottom of the cylinder 3 is provided with a circular hole 4, and the center of the circular hole 4 is at the same position as the center of the cylinder bottom; the circular hole at the bottom of the cylinder is provided with a "T"-shaped blocking part 5 , the "T"-shaped blocking part 5 includes a circular blocking piece 51 and a cylindrical protruding portion 52 fixed below the circular blocking piece 51, the cross-sectional diameter of the cylindrical protruding portion is smaller than the diameter of the circular hole, and the circular The diameter of the baffle is greater than the diameter of the circular hole, and the diameter of the circ...

Embodiment 2

[0027] This embodiment has made the following improvements on the basis of Embodiment 1: in the circular hole, around the cylindrical protruding part of the "T" shaped blocking part, there are many pairs of retaining strips 8, and each pair of retaining strips is respectively about the circle. The center of the circular hole is symmetrical, and one end of each retaining bar away from the cylindrical protruding part is respectively fixed on the circular hole. The effect of setting multiple pairs of retaining bars is to limit the left and right movement of the "T" shaped blocking parts. The quantity of retaining bar 8 can be set according to actual needs, such as Figure 4 As shown, in this embodiment, two pairs of retaining strips are provided around the cylindrical protruding part of the "T" shaped blocking part in the circular hole, and each pair of retaining strips is respectively symmetrical about the center of the circular hole. The ends of the retaining strips 8 away from...

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...
