Description

Technical Field

[0001] The utility model belongs to the technical field of geological exploration, and in particular relates to a sampling device for geological disaster exploration. Background Art

[0002] The field of geological engineering is a leading engineering field that takes natural science and earth science as its theoretical basis, with geological surveys, surveys and explorations of mineral resources, and engineering problems related to the geological structure and geological background of major projects as its main objects, and uses geology, geophysics and geochemistry techniques, mathematical geological methods, remote sensing technology, testing technology, computer technology, etc. as its means to serve the national economic construction. Geological exploration is a key investigation and research work on the geological conditions such as rocks, stratigraphic structures, minerals, groundwater, and landforms in a certain area based on the needs of economic construction, national defense construction, and scientific and technological development.

[0003] In the Chinese patent with publication number CN216791710U, a sampling device for geological disaster exploration is mentioned, which relates to the field of soil sampling technology, including a fixed cylinder and a handle. When the connecting rod descends into the underground, the sampling groove will be blocked by a sealing plug, so that the soil cannot enter the interior of the sampling groove. When the lower end of the connecting rod reaches the position where sampling is required, the personnel can pull up the positioning rod to compress the sealing plug backward and return the compression spring to the inner side of the groove. Once the sealing plug is separated from the sampling groove, the personnel can lift the device upward. At this time, the guide plate on one side of the lower end of the sampling groove will scrape the soil, so that the soil can slide into the interior of the sampling groove to fill it. When the device is fully raised, the personnel can remove the auger rod and then loosen the positioning rod. The rebounded positioning rod will drive the piston plate to move downward to push out all the soil collected in the sampling groove. At the same time, the sealing plug will be re-engaged in the inner side of the sampling groove for sealing, which greatly improves the accuracy of soil sampling.

[0004] Compared with the above documents, although the above documents greatly improve the accuracy of soil sampling, since the sampling work of geological exploration is to insert the sampling rod into the geological soil to be tested and sample the soil inside, the soil is accordingly attached to the outer wall of the sampling rod. When storing and placing the rod, the outer wall needs to be cleaned separately, which correspondingly increases the operating steps of the staff for soil sampling in geological disaster exploration, thereby reducing the work efficiency of the staff for soil sampling in geological disaster exploration. For this reason, a sampling device for geological disaster exploration is proposed. Utility Model Content

[0023] like Figure 1-3 As shown, the sliding protection mechanism is used to block the bottom of the protection box 1 and protect the sampling rod 304. The sliding protection mechanism is located at the bottom of the protection box 1. The sliding protection mechanism includes a sliding baffle 4 and a mounting ring 406. A limiting slide groove 401 is provided at the bottom of the protection box 1. The limiting slide groove 401 is fixedly connected to the limiting cross bar 402 inside. The outer wall of the limiting cross bar 402 is slidably connected to the limiting slider 404. A telescopic spring 403 is fixedly connected to one side of the inner wall of the limiting slide groove 401. A circular opening corresponding to the sliding baffle 4 is provided at the bottom of the protection box 1. Both sides of the inner wall of the circular opening are provided with mounting grooves 405. The bottom of the mounting groove 405 extends to the outside of the circular opening. A mounting magnetic block 409 is fixedly connected to the inside of the mounting groove 405. Both sides of the mounting ring 406 are fixedly connected to mounting plates 407. One end of the mounting plate 407 away from the mounting ring 406 is fixedly connected to a fixed magnetic block 408.

[0024] The utility model is further specifically described in detail. The sampling rod 304 is corresponding to the circular mouth, and the outer wall diameter of the sampling rod 304 is smaller than the inner wall diameter of the circular mouth. A plurality of cleaning brushes are connected to the inner wall of the mounting ring 406. An arc groove is provided at one end of the sliding baffle 4. The groove diameter of the arc groove is corresponding to the outer wall diameter of the sampling rod 304. The sliding baffle 4 is slidingly fitted with the circular mouth. The outer wall of the mounting plate 407 is slidingly fitted with the inner wall of the mounting groove 405. The fixed magnetic block 408 and the mounting magnetic block 409 are correspondingly arranged with opposite poles attracting each other. The outer wall of the limit slider 404 is slidingly fitted with the inner wall of the limit slide groove 401. The end of the telescopic spring 403 away from the limit slide groove 401 is connected to the outer wall of the limit slider 404, and the telescopic spring 403 is sleeved on the outer wall of the limit cross bar 402. The outer wall diameter of the mounting ring 406 is corresponding to the inner wall diameter of the circular mouth.

[0025] It should be noted that: a sampling cavity is provided inside the sampling rod 304, a sampling port is provided next to the sampling cavity, and the working principle of soil sampling and collection is the same as the working principle in the above-mentioned reference document, which is the prior art and its working principle will not be described in detail;

[0026] As can be seen from the above, when the staff samples the soil for geological disaster exploration, they slide the sliding baffle 4 to disengage it from the circular opening, and then turn on the servo motor 3 in the forward direction to make it work. When the servo motor 3 works, it drives the threaded rod 301 to rotate. According to the threaded connection between the lifting plate 303 and the threaded rod 301, it drives the sampling rod 304 to move downward, so that the sampling rod 304 extends to the outside of the protection box 1 through the circular opening. At this time, the outer wall of the sampling rod 304 and the arc groove at one end of the mounting plate 407 are pressed against and slid, and the sampling rod 304 extends to the outside of the protection box 1. At this time, the sampling rod 304 is in contact with the soil to be sampled, and then the servo motor 3 continues to work, and continues to drive the sampling rod 304 to extend, so that it is inserted into the interior of the soil. According to the sampling cavity provided inside, and the sampling port provided on one side of the sampling cavity, the soil can enter the interior of the sampling cavity through the sampling port to sample and collect the soil.

[0027] After the sampling is completed, the servo motor 3 is reversed to drive the sampling rod 304 to be stored inside the protection box 1. When the sampling rod 304 is separated from the soil, the sampled soil inside can be dumped out so that the staff can investigate the soil. Then the servo motor 3 is further reversed to move the sampling rod 304 to the inside of the protection box 1 for storage. The outer wall of the sampling rod 304 can be automatically slid and cleaned by a plurality of cleaning brushes arranged on the inner side of the mounting ring 406, so as to reduce the adhesion of soil to the outer wall of the sampling rod 304 and reduce the corrosion effect of the soil on the outer wall of the sampling rod 304. The use effect of the sampling rod 304 is improved, and the staff does not need to clean the outer wall of the sampling rod 304 separately, which correspondingly reduces the operating steps of the staff in soil sampling for geological disaster exploration, thereby improving the staff's work efficiency in soil sampling for geological disaster exploration. When the sampling rod 304 is separated from the sliding baffle 4, the sliding baffle 4 automatically blocks the circular opening according to the action of the telescopic spring 403, so that the sampling rod 304 can be stably protected inside the protection box 1 to avoid corrosion by the outside air when it is placed, thereby further improving the use effect of the sampling rod 304.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
