Specific implementation manners

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0020] Please refer to Figures 1 - 5 , the present utility model provides a technical solution: a geotechnical sampling device for water conservancy project detection, including a support ring 1. Four threaded cylinders 2 are fixedly installed at the bottom of the support ring 1. Studs 3 are threadedly connected to the inner sides of the four threaded cylinders 2. A cone 4 is fixedly installed at the bottom of the stud 3. Four support cylinders 5 are fixedly installed at the top of the support ring 1. A return spring 17 is fixedly installed at the bottom of the inner cavities of the four support cylinders 5. An inner column 6 is fixedly installed at the top of the return spring 17. A top plate 20 is fixedly installed at the top of the inner column 6. Two handles 7 are fixedly installed at the top of the top plate 20. A connecting cylinder 8 is fixedly sleeved inside the top plate 20. A threaded bar 9 is arranged inside the top end of the connecting cylinder 8. A gasket 14 is fixedly installed inside the connecting cylinder 8. One side of the bottom end of the connecting cylinder 8 is communicated with a connecting pipe 11. The other end of the connecting pipe 11 is installed with a one - way air - intake valve 12. A Y - drain pipe 13 is communicated with the bottom of the connecting cylinder 8. A servo - motor 10 is fixedly installed at the bottom of the top plate 20. The output end of the servo - motor 10 is drivingly connected to a transmission shaft 19. A sleeve 18 is movably sleeved on the outer side of the transmission shaft 19. A drill cylinder 15 is fixedly installed at the bottom of the sleeve 18. A plurality of drill teeth 16 are provided at the bottom end of the drill cylinder 15. A fixing bolt 22 movably penetrates through the inside of the sleeve 18. A plurality of diversion holes 21 are provided at the top of the drill cylinder 15.

[0021] Working principle of the above technical solution: During use, the operator transports the device to the sampling position with the mobile cart and rotates the stud 3 according to the supporting ground where sampling is required, so as to adjust the length of the threaded cylinder 2 and the stud 3, and make the cone 4 contact the ground for support. Then, the water bottle is inverted and screwed into the inside of the connecting cylinder 8 and the threaded strip 9. Then, an external power supply is connected to start the servo motor 10 to rotate. After the servo motor 10 rotates, it drives the transmission shaft 19 to rotate. The rotation of the transmission shaft 19 drives the drill cylinder 15 to rotate through the sleeve 18 and the fixing bolt 22. At this time, the operator applies a downward pressure on the top plate 20 by holding the handle 7, so that the drill teeth 16 contact the rock surface and drill and sample the rock surface. At the same time, the water flow is respectively guided through the Y drain pipe 13 to the outside of the drill cylinder 15 for easy inflow into the gaps of the cut rock, and the other is guided to the inside of the diversion hole 21, so that the water flow can be introduced into the inside of the drill cylinder 15 through the diversion hole 21 during timed start-stop sampling, facilitating the formation of water flow lubrication and cooling inside and outside, facilitating cutting and sampling. The overall structure is small and convenient to carry, and can well adapt to on-site operations.

[0022] In another embodiment, as Figures 1 - 5 shown, the inner column 6 is movably sleeved inside the support cylinder 5, and the four support cylinders 5 are evenly distributed in a circle on the top of the support ring 1.

[0023] The movable sleeve connection between the inner column 6 and the support cylinder 5 is kept stable under the support of the return spring 17. When the operator presses down and moves up the top plate 20 through the handle 7, the return spring 17 provides a force, facilitating cooperation with the operator's pressing down and moving up, increasing the feel control force while being able to reduce the force for the operator to lift, further increasing the overall operation convenience.

[0024] In another embodiment, as Figures 1 - 5 shown, the four threaded cylinders 2 are evenly distributed in a circle at the bottom of the support ring 1, and the positions of the threaded cylinders 2 correspond to the positions of the support cylinders 5.

[0025] The threaded cylinder 2 provides support for the support ring 1, facilitating the maintenance of relative stability of the structure, increasing the overall use effect, and facilitating torque stability.

[0026] In another embodiment, as Figures 1 - 5 shown, the fixing bolt 22 movably penetrates through the sleeve 18 and the transmission shaft 19 and extends to the outside of the sleeve 18.

[0027] In this solution, through the through-tightening setting of the fixing bolt 22, the fixing bolt 22 can be removed after sampling is completed, and the drill cylinder 15 and the sleeve 18 can be removed from the bottom of the transmission shaft 19, facilitating the replacement of the sampling cylinder and the operation of the sample inside the sampling cylinder, increasing convenience, facilitating the replacement operation and facilitating the extraction of the sample.

[0028] In another embodiment, as Figures 1 - 5 shown, the two ends of the Y-shaped drain pipe 13 away from the sleeve 18 are respectively communicated with the top of the drill pipe 15 and the outside of the drill pipe 15, and the diversion holes 21 are evenly distributed in a circle on the top of the drill pipe 15.

[0029] The water flow is respectively diverted through the diversion of the Y-shaped drain pipe 13 to the outside position of the drill pipe 15 for easy inflow into the gaps for cutting the rock, and the other is diverted to the inside of the diversion holes 21, so that the water flow can be introduced into the inside of the drill pipe 15 through the diversion holes 21 during timed start-stop sampling, facilitating the formation of water flow lubrication and cooling inside and outside, and facilitating the auxiliary operation.

[0030] In another embodiment, as Figures 1 - 5 shown, the diameter range of the connecting cylinder 8 is 28 mm - 30 mm, and the pitch range of the threaded strip 9 is 2 mm - 3 mm.

[0031] This size range is adapted to the sizes of most portable water bottles on the market. During the operation, the operator can install natural water filled in a mineral water bottle inside the connecting cylinder 8, or can also install and put it in after opening the mineral water, which is convenient for further increasing the convenience of operation. The overall solution is easy to use, convenient for erection and handling, and convenient for on-site sampling.

[0032] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
