Description

Technical Field

[0001] This utility model belongs to the field of groundwater collection technology, and relates to a supporting device for collecting groundwater using a Belle tube, specifically a Belle tube water collection auxiliary device. Background Technology

[0002] Groundwater sampling is a crucial step in groundwater analysis. It is a prerequisite for the accuracy of the analysis results; improper sampling will compromise the accuracy of subsequent analysis.

[0003] Currently, Bayler tubes are commonly used for groundwater sampling in China. However, transferring water samples from the Bayler tube to the sampling bottle presents several problems: the transfer process is inconvenient and inefficient, and human contact with the water sample during the process can easily lead to contamination; the groundwater sample entering the sampling bottle should be free of obvious impurities such as mud and sand, but effective separation is difficult to achieve during the transfer process. Therefore, there is an urgent need for an auxiliary tool for groundwater sampling to ensure that when using Bayler tubes to collect groundwater, effective separation can be achieved, human contact can be reduced, and the sample can be transferred from the Bayler tube to the sampling bottle in a portable and efficient manner. Utility Model Content

[0004] This invention provides a water sampling auxiliary device for a Beller pipe, which aims to overcome the above-mentioned shortcomings in the prior art.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A Bayler tube water sampling auxiliary device includes a straight cylinder, a conical cylinder and a threaded joint. The conical cylinder is coaxially and fixedly connected to the lower end of the straight cylinder through its thick end. The thin end of the conical cylinder is coaxially and fixedly connected to the upper end of the threaded joint. Multiple inclined support columns are fixed inside the straight cylinder near its lower end and extend downward into the conical cylinder. The lower ends of the multiple inclined support columns are connected to each other near the central axis of the conical cylinder, and a vertically extending column is fixed at the connection point. A filter screen is provided in the gap between each adjacent inclined support column. The threaded joint is threadedly connected to the mouth of the sampling bottle. A breathable structure is reserved between the inner wall of the straight cylinder and the outer wall of the Bayler tube.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, the breathable structure includes a plurality of guide strips evenly spaced on the inner wall of the straight cylinder, the guide strips extending vertically, and a breathable gap being formed between adjacent guide strips.

[0008] Furthermore, the upper end of the guide bar is configured as a wedge shape to guide the lower end of the Belle tube into the straight cylinder.

[0009] Furthermore, the breathable structure includes a plurality of guide rings spaced apart from top to bottom on the inner wall of the straight cylinder, and each guide ring has a breathable notch.

[0010] Furthermore, the breathable structure includes a plurality of breathable tubes that are closely attached to the inner wall of the straight cylinder. The upper end of the breathable tube extends to near the upper end of the straight cylinder, and the lower end extends downward along the inner wall of the straight cylinder to below the connection between the inclined support and the straight cylinder.

[0011] Furthermore, the materials of the straight cylinder, tapered cylinder, threaded joint, inclined support, and column are rigid plastic or stainless steel.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The Bayler tube water sampling auxiliary device provided by this utility model has a straight cylinder, a conical cylinder, inclined support columns, and a vertical column. After water is collected by the Bayler tube, the lower end is directly inserted into the straight cylinder from the top. The vertical column then pushes the stop ball inside the lower opening of the Bayler tube upwards to automatically discharge water. The discharged water is filtered through a filter screen to remove impurities such as mud and sand, and then enters the sampling bottle below through the conical cylinder and threaded joint. Moreover, each inclined support column can also support the lower end face of the Bayler tube. If necessary, the Bayler tube can be placed directly by hand, which is more labor-saving. During the entire sampling and transfer process, the sampling personnel will not come into contact with the water sample, and the probability of human contamination of the water sample is small. The threaded joint is threaded to the mouth of the sampling bottle to ensure that leakage is not likely. The inner wall of the Bayler tube is equipped with a breathable structure, which allows air inside the bottle to be easily discharged when the water flows downward into the sampling bottle, resulting in higher sampling efficiency.

[0020] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0021] In the description of this utility model, if terms such as "upper", "lower", "left", "right", "top", "bottom", "inner", and "outer" are used to indicate the orientation or positional relationship, the orientation or positional relationship indicated is based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] like Figures 1 to 4 As shown, this utility model provides a water sampling auxiliary device for a Belle tube, which includes a straight cylinder 1, a conical cylinder 2, and a threaded connector 3. The conical cylinder 2 is coaxially and fixedly connected to the lower end of the straight cylinder 1 through its thick end, and the thin end of the conical cylinder 2 is coaxially and fixedly connected to the upper end of the threaded connector 3. A plurality of inclined support columns 4 are fixedly installed in the straight cylinder 1 near its lower end, extending downward into the conical cylinder 2. The lower ends of the plurality of inclined support columns 4 are connected to each other near the central axis of the conical cylinder 2, and a vertically extending column 5 is fixed at the connection point. A filter screen 6 is provided in the gap between each adjacent inclined support column 4. The threaded connector 3 is threadedly connected to the mouth of the sampling bottle. A breathable structure is reserved between the inner wall of the straight cylinder and the outer wall of the Belle tube.

[0023] It should be noted that the threaded connection between the threaded connector and the sampling bottle can be either an internal thread on the connector and an external thread on the bottle opening, or vice versa. The venting structure is designed to ensure that when water flows downward through the filter into the sampling bottle, the air inside the bottle can be smoothly expelled upwards, preventing excessive pressure inside the bottle due to poor airflow, which could prevent the water sample from entering the sampling bottle smoothly.

[0024] In one embodiment of this utility model, such as Figure 3 As shown, the breathable structure includes a plurality of guide strips 7 evenly spaced on the inner wall of the straight cylinder 1. The guide strips 7 extend vertically, and a breathable gap is formed between adjacent guide strips 7. The upper end of the guide strip 7 is set in a wedge shape to guide the lower end of the Bayer tube into the straight cylinder 1. That is, the guide strip is thinner the closer it is to the top of the straight cylinder. In this way, the closer it is to the top of the straight cylinder, the larger the internal space of the straight cylinder, and the easier it is to insert the lower end of the Bayer tube into the opening at the top of the straight cylinder.

[0025] In another embodiment of this utility model, the breathable structure includes a plurality of guide rings spaced apart from top to bottom on the inner wall of the straight cylinder 1. Each guide ring has a breathable notch. Although no corresponding drawings are given for the guide rings and breathable notches, those skilled in the art should be able to understand their structure based on the above description. In addition, in order to also have a guiding effect on the Belle tube, the inner diameter of the guide rings closer to the upper end of the straight cylinder is larger.

[0026] In another embodiment of this utility model, such as Figure 4 As shown, the breathable structure includes several breathable pipes 8 that are closely attached to the inner wall of the straight cylinder 1. The upper end of the breathable pipe 8 extends to near the upper end of the straight cylinder 1, and the lower end extends downward along the inner wall of the straight cylinder 1 to below the connection between the inclined support 4 and the straight cylinder 1.

[0027] It should be noted that, in addition to facilitating the exhaust of air from the sampling bottle as mentioned above, the venting structure in the form of a venting tube also helps to ensure consistent air pressure between the upper and lower sections of the filter screen, thereby improving filtration efficiency.

[0028] In the above embodiments, the straight cylinder 1, tapered cylinder 2, threaded joint 3, inclined support 4, and column 5 are made of rigid plastic or stainless steel.

[0029] It is understandable that straight cylinders, tapered cylinders, and threaded joints can be integrally formed from the same material.

[0030] When using the Beller pipe water sampling auxiliary device of this utility model, such as Figure 1 As shown, after the Belle tube 9 collects water, its lower end is directly inserted into the straight cylinder 1 from above. The column 5 then pushes the stop ball 10 inside the lower opening of the Belle tube upwards to automatically discharge water. The water in the Belle tube flows out from the lower opening and is filtered by the filter screen 6 to remove impurities such as mud and sand. Then it passes through the cone 2 and the threaded joint 3 and enters the sampling bottle below.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
