Technical Field

[0001] The invention relates to the technical field of sampling devices, and in particular to a desert brine sampling device and method. Background Art

[0002] Brine refers to liquid minerals with a salt content greater than 5%. Brine that accumulates on the surface is called surface brine or lake brine. Brine that accumulates below the ground is called underground brine. In order to study underground brine, it is necessary to use a sampler to sample the brine underground, collect it and then conduct testing and analysis. In the past, when sampling brine in a desert environment, manual excavation was often used to dig 3 to 4 meters underground, and 3 to 5 brine samples could be taken every day. This not only consumed a lot of manpower and material resources, but also had extremely low sampling efficiency. Therefore, it is urgent to design an efficient sampling tool and sampling method to improve the efficiency of brine sampling in desert areas. Summary of the invention

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] The purpose of the present invention is to provide a desert brine sampling device and method to solve the problems existing in the above-mentioned prior art and to improve the brine sampling efficiency in desert areas.

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] In view of the known brine sampling in desert areas, it is necessary to manually dig downward until brine appears to realize sampling. In order to improve the sampling efficiency, the present invention provides a desert brine sampling device, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it includes an auger 1, which has a hollow cavity, and a drill rod 3 is connected to the top of the auger, and a drilling tooth 101 is provided at the bottom. The drilling tooth 101 is a spiral blade structure. A plurality of spiral blade structures are arranged on the side of the bottom of the auger 1. The use of the spiral blade structure makes it convenient and labor-saving to drill through the sand layer, and the labor intensity is low. The drill rod 3 can drive the auger 1 to drill downward, and when brine can be observed in the borehole; the sampling tube 2 is placed in the hollow cavity of the auger 1 and extended into the bottom of the borehole. A sampling port 201 is opened on the side wall of the sampling tube 2, and brine can enter the sampling tube 2 through the sampling port 201. There is no need for manual excavation and sampling, which improves the sampling efficiency.

[0033] In order to facilitate installation and storage, the drill rod 3 of this embodiment includes multiple extension rods 301, each of which is 1.5 meters long. The multiple extension rods 301 are fixedly connected end to end in sequence through threads, and the extension rod 301 located at the bottom is fixedly connected to the top of the auger 1, which is convenient for installation and disassembly. In a specific embodiment, different augers 1 can be replaced according to different sampling layers; in order to facilitate drilling and sampling, a cross handle 4 is threadedly connected to the top of the drill rod, so that the operator can hold the cross handle 4, rotate and press down the drill rod, and realize the drilling of the auger 1.

[0034] In order to facilitate drilling and sampling, the auger 1 of this embodiment includes a barrel 103 with openings at both ends, a hollow cavity is provided in the barrel 103, a plurality of drilling teeth 101 are integrally formed on the side of the bottom of the barrel 103, and an inverted U-shaped connecting frame 102 is provided at the top of the barrel 103. The top of the inverted U-shaped connecting frame 102 is connected to the drill rod 3, so that when drilling, sand can fill the hollow cavity, and then the auger 1 is lifted upward, and the drilling can be repeated after the sand is removed, and the hole can be drilled quickly until brine can be observed. In this embodiment, a slot 104 is provided on the inner side of the top of the barrel 103, and a hook 203 is provided on the top of the sampling barrel 2. The hook 203 can be snapped into the slot 104, so that the sampling barrel 2 can be fixed in the hollow cavity, which is convenient for the sampling barrel 2 to follow the auger 1 into the bottom of the borehole to sample brine.

[0035] In a preferred embodiment, two symmetrical elliptical openings are opened on the side wall of the barrel 103 of the auger 1, and the sampling port 201 of the sampling tube 2 is located at the elliptical opening, so that the side wall of the auger 1 will not hinder the brine from entering the sampling tube 2 from the sampling port 201.

[0036] The sampling tube 2 of the present embodiment is closed at the bottom, connected to a sealing cover at the top, and the side wall of the sampling tube 2 is a double-layer structure; the sampling port 201 passes through the side wall in the middle of the sampling tube 2, and absorbent sponges are provided between the inner side wall and the outer side wall of the sampling tube 2, and the absorbent sponges are located at the sampling port 201. A water intake port 202 is provided on the upper side wall of the sampling tube 2. When the underground brine content is low, the brine is absorbed by the absorbent sponge to enter the sampling tube 2 and is taken to the surface. When the brine content is high, the water intake port 202 can be directly used to fill the sampling tube 2 with brine and lift it to the surface.

[0037] The present invention also provides a method for sampling desert brine, comprising the following steps:

[0038] Step 1: Use a shovel to scrape away the soft fine sand on the surface at the sampling location; use a wrench to assemble the auger 1, the cross handle 4 and the extension rod 301;

[0039] Step 2: Place the auger 1 at the sampling position, press and turn the cross handle 4 to drive the auger 1 to drill downward, and after the hollow cavity of the auger 1 is filled with sand, lift it up from the borehole, remove the sand inside, and then re-insert it into the borehole for drilling;

[0040] Step 3, repeating step 3 until the sand layer is penetrated and brine is observed in the borehole;

[0041] Step 4: Install the sampling tube 2 into the hollow cavity of the auger 1, and insert it into the borehole to take out the brine.

[0042] When the brine content in the desert is relatively low, and no observable brine appears after drilling a hole to a set depth at the sampling position using the auger 1, the sampling tube 2 may not be used, and the auger 1 may be used instead to take the sand containing brine at the bottom of the hole to the surface. At this time, the funnel 5 and the sampling bottle 6 are introduced, gauze is laid in the funnel 5, and then the bottom of the funnel 5 is set at the opening of the sampling bottle 6, the sand containing brine is poured onto the gauze in the funnel 5, and the sand containing brine is filtered, so that the brine in the sand is filtered into the sampling bottle 6, and the sampling bottle 6 is repeatedly cleaned with the taken out brine to ensure that the sample is contaminated and the sampling is completed.

[0043] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
