[0002] During the construction and production of underground mines, hydrographic holes are generally arranged within the mining area to master the hydrographic data of the mining area. To master the relationship between each hydrographic hole, especially the relationship between underground water inrush and surface water, it is necessary to regularly sample each hydrographic hole. Since the hydrographic holes are generally relatively deep and have a small diameter, when using a general container for sampling, due to the buoyancy effect of the water bucket, the sampling process is generally difficult.

[0014] The following further illustrates the present utility model through examples in conjunction with the accompanying drawings.
[0015] Referring to the attached Figure 1-2 , a sampling device applicable to deep holes includes a sealing cone 1, a container cylinder 2, a floating guide rod 3, a pressing plate 4, a gravity weight 5, a locking nut 6, a suspension rope 7, and a water inlet hole 8. A water inlet hole 8 is provided at the bottom of the container cylinder 2, and a hole matching the floating guide rod 3 is provided at the top of the container cylinder 2. The lower end of the floating guide rod 3 is fixedly connected to the sealing cone 1, and the sealing cone 1 cooperates with the water inlet hole 8 at the bottom of the container cylinder 2. The upper end of the floating guide rod 3 passes through the hole at the top of the container cylinder 2 that matches the floating guide rod 3 and is connected to the suspension rope 7. A pressing plate 4, a gravity weight 5, and a locking nut 6 that cooperate with the top of the container cylinder 2 are provided on the floating guide rod 3.
[0016] In this embodiment, referring to the attached Figure 1-2 , this sampling device is applicable to sampling of small-diameter and deep holes, and the size of its container cylinder 2 matches the diameter of the vertical deep hole 10.
[0017] The floating guide rod 3 is located at the central position inside the container cylinder 2, and its length is greater than the height of the container cylinder 2. The lower end of the floating guide rod 3 is fixedly connected to the sealing cone 1, and the sealing cone 1 cooperates with the water inlet hole 8 at the bottom of the container cylinder 2. Moreover, a rubber with a sealing function is lined at the contact part between the sealing cone 1 and the container cylinder 2. The upper end of the floating guide rod 3 is connected to the suspension rope 7. A pressing plate 4, a gravity weight 5, and a locking nut 6 that cooperate with the top of the container cylinder 2 are also provided near the upper end of the floating guide rod 3. The pressing plate 4 is fixed on the floating guide rod 3, the gravity weight 5 is placed on the pressing plate 4, and is fixed on the pressing plate 4 through the locking nut 6. The size of the gravity weight 5 can be replaced according to the density of the sampling medium.
[0018] The working process of the present utility model is as follows:
[0019] Referring to the attached Figure 1, when the sampling device is lowered, the tension of the suspension rope 7 is transmitted to the container cylinder body 2 through the floating guide rod 3 and the sealing cone 1, and the whole device is lowered. When the sampling device contacts the sampling medium, the container cylinder body 2 floats on the surface of the medium under the buoyancy force, and the gravity of the gravity block 5 acts on the sealing cone 1 through the floating guide rod 3. The sealing cone 1 moves downward, opening the water inlet channel between the sealing cone 1 and the container cylinder body 2 to complete the bottom water inlet process. After sampling, the suspension rope 7 of the sampling device is lifted upward. The suspension rope 7 pulls the floating guide rod 3 and drives the sealing cone 1 to move upward. The sealing cone 1 contacts the container cylinder body 2 again, and the effective sealing of the bottom of the sampling device is achieved by relying on the rubber with a sealing function between the sealing cone 1 and the container cylinder body 2 to complete the sampling work. At the same time, by using the replaceability of the gravity block 5, according to the different densities of the sampling medium, the specifications of the gravity block 5 are flexibly matched to achieve a reasonable match between the sealing cone 1 and the gravity block 5.
