Among them, the sampling structure 1 is provided with multiple structures, which are used to perform rock and soil sampling in water conservancy projects. The base structure 2 is used for positioning, fixing the sampling device at the location of rock and soil sampling, reducing sampling errors and increasing sampling accuracy.

[0034] In this embodiment, Figure 1-Figure 3As shown, the sampling structure 1 includes a sampling tube 11, and a connecting rod 12, a motor seat 13 and a motor 14 are arranged in sequence above the sampling tube 11, and handles 15 are symmetrically arranged on both sides of the motor seat 13. The handle 15 is U-shaped, and its two ends are fixed to the side of the motor seat. When sampling, the sampling structure 1 is first lowered to a suitable position by using the driving structure 4 in combination with the limiting structure 3, and then the motor 14 is turned on. Under the rotation of the motor 14, the sampling tube 11 can be rotated for sampling. In actual application, the lower end of the sampling tube 11 is provided with teeth, which is convenient for the sampling tube to be inserted into the rock and soil.

[0035] Specifically, if Figure 3-Figure 4 As shown, the base structure 2 includes a bottom plate 21 and a top plate 22, wherein the bottom plate 21 is provided with a positioning hole 23, and a fixing member such as an anchor bolt or other anchor rod is passed through the positioning hole 23, so that the bottom plate 21 can be fixed to the rock ground, that is, the base structure 2 can be fixed to the rock ground. The bottom plate 21 is also provided with a first through hole 24, and the bottom plate 22 is provided with a second through hole 25. The top plate 22 is connected to the bottom plate 21 through a column 26, and a limit frame is arranged between the top plate 22 and the bottom plate 21, and the limit frame is a limit frame for limiting the lower end of the sampling structure 1.

[0036] More specifically, the limit frame includes a plurality of limit sleeves 27, and the limit sleeves 27 are made of round tubes that are transparent from top to bottom; the limit sleeves 27 are reinforced by connecting plates 28 to ensure the integrity of the base structure. The first through hole 24 opened on the bottom plate 21 is adapted to each limit sleeve 27. The second through hole 25 opened on the top plate 22 is also adapted to each limit sleeve 27. That is, the base structure 2 has a plurality of holes that are transparent from top to bottom, and each sampling structure can be inserted into them respectively, so as to sample multiple rock and soil samples at the same time.

Then, the device is placed at the rock and soil sampling position in the water conservancy project, and the device is fixed at the rock and soil sampling position by bolts or anchor rods and other fixings to prevent shaking during the rock and soil sampling process, reduce sampling errors, and increase sampling accuracy. Adjust the two hydraulic cylinders so that the limiting structure 3 is lifted and lowered to a suitable position, at which time the sampling tube 11 of the sampling structure 1 extends into the rock and soil under the drive of the hydraulic cylinder, and at this time, the motors 14 of each sampling structure are turned on to complete the sampling of multiple rock and soil samples.

[0041] The rock and soil sampling device for water conservancy projects provided in this embodiment can prevent the sampling structure from shifting during the sampling process by arranging mutually compatible limiting structures and base structures, thereby reducing rock and soil sampling errors in water conservancy project operations and increasing operation accuracy.
