Embodiment 1

[0022] see Figure 1-5 , a slow-sinking baffle-type surface water collector, comprising an upper cover 1 and a lower cover 8 detachably and sealingly connected with the upper cover 1, a pull rope 11 is connected to the top of the upper cover 1, and a floating ball is fixed on the pull rope 11 10. Two symmetrically arranged sampling bottles 2 are fixedly installed in the lower cover 8, and the sampling bottles 2 are used for filling and storing seawater to be sampled. The bottom of the lower cover 8 is provided with a water inlet hole 14 through which seawater can enter the interior of the lower cover 8 and finally enter the sampling bottle 2 to be collected.

[0023] Two arc-shaped iron sheets 3 are fixedly installed on the inner bottom of the lower cover 8, and a bracket 15 is fixed on the bottom of the lower cover 8. The bracket 15 provided plays an overhead role on the slow sinking component to prevent the slow sinking component from contacting the ground. The metal rod 7 ...

Embodiment 2

[0030] On the basis of Embodiment 1, the slow sinking assembly can be replaced by a counterweight box 16, and the bottom of the counterweight box 16 is threadedly connected with a bottom cover 18. Before the water harvesting work, the bottom cover 18 is rotated to separate from the counterweight box 16, and the A counterweight of appropriate weight is added in the counterweight box 16 to realize the slow sinking effect of the counterweight box 16 in the process of the device entering seawater.

[0031] Further, the diameter of the slow-sinking component is larger than the diameter of the water inlet hole 14, so that the slow-sinking component can better shield the water inlet 14, and realize that no seawater of non-water extraction depth will enter the lower part of the device at the initial stage of sinking. Cover 8 inside.

[0032] Further, the one-way check valve 9 is at an angle of 45 degrees to the horizontal plane, and when the device is released vertically into the seaw...

Abstract

The invention discloses a slow sinking blocking sheet type surface layer water sampler and relates to the technical field of the water sampler. The slow sinking blocking sheet type surface layer watersampler comprises an upper cover and a lower cover which is in demountable sealing connection with the upper cover. The top of the upper cover is connected with a pull rope. A floating ball is fixedon the pull rope. Two symmetrically arranged sampling bottles are fixedly mounted in the lower cover. A water inlet hole is set at the bottom of the lower cover. Nuts are in threaded connection and sleeving on metal rods. A slow sinking assembly vertically corresponding to the water inlet is set at the bottom of the lower cover. The metal rods movably penetrate the slow sinking assembly. Two unidirectional check valves are fixed in a metal shell. Exhaust vents transversely corresponding to the unidirectional check valves are set on the side walls of the metal shell. According to the water sampler, two bottles of water samples can be collected at the same time, so parallelism of parallel samples is greatly improved, and moreover, sampling efficiency is also improved; and in a whole samplingprocess, the water sampler is thrown into water, redundant operation such as pulling out a release pin is avoided, the operation is greatly simplified, application learning cost is reduced, and efficiency of sampling work is improved.

Description

technical field [0001] The invention relates to the technical field of water collectors, in particular to a slowly sinking baffle type surface water collector. Background technique [0002] Water sampling device, the general term for collecting ocean, lake and river water quality samples, generally includes: instantaneous sample sampler, depth comprehensive sampler, closed-open-closed water sampling device and pumping system water sampling device, surface water sampling device Most can be classified under the category of closed-open-closed water collectors. According to the definition in the "Marine Monitoring Specification" (GB17378-2007), the surface layer in the sampling level refers to the depth range of 0.1m to 1m below the sea surface, and the monitoring elements such as petroleum and floating hazardous chemicals are mainly collected from surface samples. , so surface oil extractors are widely used in environmental monitoring. [0003] During the use of the current s...
