Description

Technical Field

[0001] This utility model relates to the field of pollution sampling equipment technology, specifically a detection-type underground pollution source sampling drill bit. Background Technology

[0002] Pollution refers to the introduction of substances harmful to humans or other organisms into the natural environment, where the quantity or degree reaches or exceeds the environment's carrying capacity, thereby altering the normal state of the environment. Specific examples include water pollution, air pollution, noise pollution, light pollution, radioactive pollution, and heavy metal pollution. Sampling refers to the process of drawing individuals or samples from a population, that is, the process of testing or observing the population. It is divided into two types: random sampling and non-random sampling. Random sampling refers to sampling methods that draw samples from the population according to randomization principles; it is without any subjectivity and includes simple random sampling, systematic sampling, cluster sampling, and stratified sampling. When sampling pollution sources, it is often necessary to drill for samples from underground pollution sources.

[0003] A previously published patent (publication number CN209670928U) discloses a sampling drill bit, including a drill bit device. The key technical features include a drill shank, a drill body, and a drill tip. The drill body is cylindrical, and a spiral-shaped cutter plate is fixedly connected to its circumference. A sampling hopper is provided on the surface of the drill body near the drill tip, and the sampling hopper is displaced on the surface of the drill body between the spiral cutter plates. A receiving groove is provided on the drill body to accommodate the sampling hopper, and the lower end of the sampling hopper is rotatably connected to the side wall of the receiving groove. A protruding force-bearing block is fixedly connected to the surface of the sampling hopper away from the drill body. This invention solves the problem of repeated drilling for sampling, which affects work efficiency, and achieves rapid sampling while ensuring sampling quality, avoiding repeated drilling, and reducing damage to the soil.

[0004] However, there are some problems in the use of existing sampling drill bits: 1. The sampling drill bits currently on the market have low detection capability for pollution sources, making it difficult to intuitively display the underground pollution situation. The overall installation of the drill bit is also low, making it inconvenient to disassemble and install, and the sampling measures are relatively cumbersome, resulting in low sampling efficiency for pollution sources; 2. The sampling drill bits currently on the market lack a mechanism for quick installation and length adjustment during the sampling process, thus reducing the overall adjustability and making it inconvenient for users to control and operate. Utility Model Content

[0005] The purpose of this invention is to provide a sampling drill bit for detecting underground pollution sources, so as to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a sampling drill bit for detecting underground pollution sources, including an installation column, a collection and detection component disposed on the surface of the installation column, and an installation adjustment component disposed on the surface of the installation column;

[0007] The collection and detection assembly includes a first drill bit that is connected to the surface of the mounting column. The surface of the first drill bit has an inner groove, and a second drill bit is disposed inside the inner groove. A collection groove is formed on the inner side of the bottom of the second drill bit, and a probe is embedded and connected to one end of the second drill bit. The pollution source sample is collected through the collection groove.

[0008] A vertical plate is fixedly connected to the surface of the mounting column, and there are multiple vertical plates located on both sides of the surface of the mounting column.

[0009] The installation adjustment assembly includes an opening at the top of the vertical plate, a connecting block connected inside the opening, a horizontal plate fixedly connected to one end of the connecting block, and a telescopic rod connected to the bottom of the horizontal plate, through which the installation column is moved.

[0010] As a further improvement of this utility model: the collection and detection component also includes an internal thread formed inside the inner groove, and a stud is connected to the surface of the internal thread.

[0011] As a further embodiment of this utility model: one end of the stud is fixedly connected to the surface of the second drill bit, and the collection groove is opened on the outer side of the stud surface.

[0012] As a further improvement of this utility model, the installation and adjustment assembly further includes a first connecting hole formed on the surface of the vertical plate, the interior of the first connecting hole communicating with the interior of the opening.

[0013] As a further embodiment of this utility model: a second connecting hole is provided on the surface of the connecting block, the first connecting hole and the second connecting hole are aligned internally, and an insert block is fixedly connected to the surface of the horizontal plate.

[0014] As a further improvement of this utility model: the surface of the mounting column is provided with an insertion hole, and an insertion block is connected inside the insertion hole.

[0015] As a further embodiment of this utility model: a breaking block is fixedly connected to the surface of the second drill bit, a protective ring is fitted to the surface of the second drill bit, the probe is located inside the protective ring, one end of the telescopic rod is detachably connected to a mounting base, and one end of the mounting base is fitted to a mounting block.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. When drilling is required for detection, the device inside the mounting column rotates a first drill bit connected to it. One end of the first drill bit is connected to a stud through an internal groove, and the stud is stably connected to the internal thread of the groove. A second drill bit is fixedly connected to one end of the stud. The rotation of the first drill bit drives the rotation of the second drill bit, allowing for convenient drilling and sampling underground. When the second drill bit reaches the pollution source, it collects the broken sample through a collection groove at one end. The user can then retrieve the mounting column, increasing the convenience of sampling. During drilling, a probe embedded in one end of the second drill bit detects the pollution source, increasing the overall detectability. The sampling drill bit has high detectability of pollution sources, making it easy to visually display the underground pollution situation. The drill bit has high installation flexibility, making it easy to disassemble and install, and the sampling method is relatively simple, improving the sampling efficiency of pollution sources.

[0018] 2. When the overall position of this utility model needs to be adjusted during drilling, the user installs the mounting base through the mounting block, and connects the telescopic rod through the mounting base. One end of the telescopic rod is connected to multiple connecting blocks through a horizontal plate, so that the connecting blocks are inserted into the vertical plate fixedly connected to the surface of the mounting column. The connecting blocks are connected to the opening at one end of the vertical plate. After the connecting blocks are inserted into the vertical plate, the second connecting hole on the surface of the connecting block is aligned with the first connecting hole on the surface of the vertical plate, and the external bolts are tightened to increase the connection. At this time, the power current output terminal of the telescopic rod is connected by an external power source, and the telescopic rod works to drive the horizontal plate to adjust the length, thereby adjusting the movable length of the mounting column. Then, the sampling drill bit as a whole has a mechanism that can quickly install and adjust the length during the sampling process, thereby improving the overall adjustability and facilitating the user's control operation.
