Description

Technical Field

[0001] This application relates to the field of sampler technology, and in particular to a prototype water sample rapid acquisition device. Background Technology

[0002] Currently, in the context of marine and coastal engineering, the collection and sampling of prototype water samples (a mixture of water, pollutants, and sediment) in the field is crucial for research in this specialized area. Commonly used sampling instruments are diverse, including grab samplers, horizontal samplers, pull samplers, and bellows samplers. However, all of these samplers are suspended in the water by cables, and due to the shape and size of the sampler itself, it is inevitably impacted by the water flow underwater, causing it to stray from its intended sampling location. Furthermore, when the current is strong, the sampler is not only pushed far from its intended sampling area by the high-speed current, but also fails to effectively collect water samples from the middle to the bottom layers. Therefore, these types of samplers are generally only suitable for waters with low current speeds.

[0003] Furthermore, after each sampling, this type of sampler requires pulling it out of the water, opening it, and emptying the water sample before it can be lowered back underwater for sampling again. Therefore, the sampling process involves frequent up-and-down movements, which is cumbersome and time-consuming, especially in deep waters where the sampling process can be extremely lengthy, significantly reducing the time available for other tests.

[0004] Therefore, this invention addresses the problem of high-speed water flow with velocities greater than 1.5 m / s, which is frequently encountered in coastal and marine engineering projects, and the cumbersome and time-consuming field sampling operations. Summary of the Invention

[0005] The purpose of this application is to provide a prototype water sample rapid acquisition device to solve the problems of long sampling time and inconvenience in the prior art.

[0006] To solve the above-mentioned technical problems, this application adopts the following technical solution:

[0007] A prototype rapid water sample acquisition device includes a bottom submerged section, an intermediate connecting section, and an upper operating section connected in sequence, forming a channel for fluid movement between the three.

[0008] The bottom submerged section includes a suction device connected to one end of the intermediate connecting section;

Obviously, the described embodiments are only part of the embodiments of the application, not all the embodiments. The description of the at least one exemplary embodiment is actually only illustrative, not as any limitation on the application and its application or use.

[0027] Reference is made to the drawings Figure 1 and 2The embodiment discloses a kind of prototype water sample fast acquisition device under field high-speed water flow environment, it includes the bottom end submerged section, intermediate connecting section, upper operating section connected in sequence, channel for fluid movement is formed between three;Bottom end submerged section includes the suction device connected with the one end of intermediate connecting section;Upper operating section one end is used for fluid discharge, and the other end is connected with the other end of intermediate connecting section;And signal connection suction device's energy equipment;Suction device works, to make fluid move in channel.

[0028] When using, the bottom end submerged section is placed in the water layer needing to be sampled, the energy equipment functions for the suction device, so that the sample water here is quickly sucked into the channel between the bottom end submerged section, intermediate connecting section and upper operating section, and is quickly discharged at one end of the upper operating section, to complete the efficient and rapid sampling of prototype water sample.

[0029] As shown in Figure 1 The bottom end submerged section in the embodiment includes variable voltage lift water pump 1, steel protective cover 2, fixed waterproof filling layer 3;Intermediate connecting section includes first steel outer sleeve 5, flexible steel wire protection net 4, flexible inner hose 6, threaded splicing section 7 and connecting wire 8.

[0030] Among them, steel protective cover 2 is used to protect variable voltage lift water pump 1, to avoid direct contact of variable voltage lift water pump with mud surface. Steel protective cover 2 is fixed on the first steel outer sleeve 5 in the form of a sleeve, and the height of steel protective cover 2 can be selected and replaced according to the near bottom bed mud concentration. When the near bottom mud concentration changes between 0~100km / m3, the height of steel protective cover 2 is preferably selected between 0.05~0.30m, following the selection principle that the higher the near bottom mud concentration, the higher the height of steel protective cover 2, and the linear relationship between them can be selected.

[0031] Among them, the pumping capacity in steel protective cover 2 should not be too large, so as to prevent the bed surface mud from entering the steel protective cover 2 after being stirred.
