Water sample collection device, system and method

Abstract

The present disclosure relates to a water sample collection device, system and method. The water sample collection device includes: a water collection cylinder, used to collect water samples at a specified depth; an electromagnetic release device, used to quickly release the hook connected to the cover of the water collection cylinder; and a settling leveling mechanism, which is used to make the water sample collection device obtain stability and obtain hydrodynamic sinking force. The subsidence leveling mechanism includes: a hydrodynamic stabilizing ring, which is used to promote the water sample collection device to enter a stable state; a sinking hydrofoil, which is used to generate a hydrodynamic sinking force; and a stabilizing wing, which is used to deflect the water sample collection device to The stable state, wherein the stable state refers to that the orientation of the water sample collection device is along the direction of water flow.

Description

technical field [0001] The present application relates to the field of water sample collection, and more specifically, to a water sample collection device, system and method. Background technique [0002] This section is provided to describe the prior art in the technical field to which this application pertains. It should be noted that the specific implementations described in this application are not limited to the realization of solving the defects and deficiencies in the prior art pointed out in this chapter, and the technical solutions claimed in this application are defined in the appended claims The book shall prevail. [0003] The development of water resources needs to obtain a large amount of accurate water sample data, which involves exploration, collection and other links. Water sample collection is especially important for the study of water resource environment. [0004] The currently widely used water collectors are composed of water collection cylinders, c...

Problems solved by technology

[0005] In this sampling process, there are two disadvantages in using ropes to hoist and retract the water collection device: on the one hand, when there is an undercurrent under the water, especially after the cover is closed, the water collection cylinder is prone to tilt (for example, vertical orientation) and / or shaking (for example, a horizontal orientation), affecting its stability; on the other hand, the flow of water exerts a force (usually a horizontal force) on the cylinder at an angle to the vertical, thereby resulting in longer lengths of cable required

However, it also has defects and deficiencies similar to those of CN207379770U and CN201917474U, that is, it is difficult to achieve a suitable compromise between the stability of the water collector during operation and the flexibility of hanging the water collector
