Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a rock and soil sampling device for water conservancy project detection. Background Art

[0002] Water conservancy and hydropower engineering technology mainly studies the basic knowledge and skills of water conservancy engineering surveying, water conservancy engineering mapping and reading, and water conservancy engineering construction. During the construction of water conservancy projects, it is necessary to inspect and survey the foundation rocks to ensure that the foundation of the area can withstand the construction of water conservancy projects. To sample the rocks, a rock and soil sampling device for water conservancy engineering testing is needed.

[0003] Patent document CN220231036U discloses a geotechnical sampling device for water conservancy project inspection, "including a bottom plate, a top plate is arranged on the top of the bottom plate, a positioning groove is arranged at the middle position inside the bottom plate, and a lifting plate is arranged between the top of the bottom plate and the bottom of the top plate. By providing a disassembly and assembly component between the bottom of the sampling tube and the top of the sampling drill bit, when in use, the installation sleeve is inserted into the bottom end of the sampling tube, and the fixing holes are respectively aligned with the positioning holes, and then the fastening bolts are passed through the positioning holes and inserted into the fixing holes and tightened, so that the installation sleeve can be fixed to the bottom end of the sampling tube, thereby achieving the purpose of fixing the sampling drill bit to the bottom end of the sampling tube, and the sampling drill bit can be replaced by removing the fastening bolts, thereby achieving the effect of convenient and quick disassembly and replacement of the sampling drill bit, ensuring the normal geotechnical sampling operation of the device during water conservancy project inspection."

[0004] The above-mentioned equipment can replace the sampling drill bit by removing the fastening bolts, thereby achieving the effect of convenient and quick disassembly and replacement of the sampling drill bit, ensuring the normal rock and soil sampling operation of the device during water conservancy project inspection. However, after the equipment finishes sampling the rock, since the diameter of the sampled rock is roughly the same as the diameter of the drill barrel when the drill barrel drills the rock, the rock gets stuck in the drill barrel and is difficult to remove. This requires staff to improve the equipment. Utility Model Content

[0005] The purpose of the utility model is to provide a rock and soil sampling device for water conservancy project detection to solve the problems raised in the above background technology.

After the drill tube descends, deeper rock formations can be sampled, thereby reducing the deviation of subsequent detection results. The reinforced telescopic rod can reinforce the support plate and the sampling structure, thereby improving the stability of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] After the rock sampling is completed, the rock in the drill barrel 5 pushes the push plate 7 to the top wall of the drill barrel 5, and the mounting plate 3 is driven to descend through the extension and retraction of the first electric telescopic rod 2. After the mounting plate 3 descends, it drives the drill barrel 5 at the bottom to descend. After the bottom of the drill barrel 5 contacts the ground, the push plate 7 is pushed down by the extension and retraction of the second electric telescopic rod 4. The push plate 7 slides in the movable groove 6, thereby pushing the rock to the bottom of the drill barrel 5 and pressurizing the rock so that the rock can maintain its original layer. The drill barrel 5 is then driven to rise through the first electric telescopic rod 2, and the second electric telescopic rod 4 drives the push plate 7 to push the rock out of the drill barrel 5, thereby completing the discharge of the sample.

[0030] Reference Figure 2 , Figure 3 and Figure 4As shown, the inner top wall of the support plate 1 is fixedly connected with a reinforced telescopic rod 9, the bottom of the reinforced telescopic rod 9 is fixedly connected with a protective box 10, and the bottom of the protective box 10 is fixedly connected to the top of the mounting plate 3, the inner wall of the protective box 10 is provided with a servo motor 11, and the top of the drill tube 5 is fixedly connected to the output end of the servo motor 11, the two sides of the bottom end of the reinforced telescopic rod 9 are fixedly connected with reinforcement blocks 12, and the bottom of the reinforcement block 12 is fixedly connected to the top of the protective box 10, and the two sides of the protective box 10 are provided with heat dissipation grooves 13;

[0031] First, the servo motor 11 is powered on, and the output end of the servo motor 11 drives the drill barrel 5 to rotate. The drill barrel 5 cuts the rock at the bottom by rotating. During the cutting process, the first electric telescopic rod 2 pushes the drill barrel 5 to descend, so that the cut rock is stored in the drill barrel 5, and the heat dissipation groove 13 can discharge the heat of the protective box 10.

[0032] Reference Figure 1 and Figure 6 As shown, support rods 14 are fixedly connected to the four sides of the bottom of the support plate 1, a universal wheel 15 is fixedly connected to the bottom of the support rod 14, a reinforcing rod 16 is fixedly connected to the inner wall of the support rod 14, a water pump 17 is fixedly connected to the top of the reinforcing rod 16, a nozzle 18 is fixedly connected to one side of the water pump 17, a slide rail 19 is slidably connected to the top of the support plate 1, a counterweight 20 is fixedly connected to the top of the slide rail 19, and the bottom of the counterweight 20 is overlapped with the top of the support plate 1;

[0033] First, connect the water pump 17 to the water source. The water source enters the nozzle 18 after passing through the water pump 17, and then is sprayed out through the nozzle 18. The sprayed water source falls on the surface of the drill tube 5, thereby evaporating and cooling the drill tube 5. The equipment can be moved by the universal wheel 15 at the bottom of the support rod 14. The counterweight block 20 can provide a certain weight for the equipment, so that the equipment can be more stable when drilling rocks. The counterweight block 20 can slide on the slide rail 19 at the bottom and be removed from the top of the support plate 1.

[0034] Working principle: the output end of the servo motor 11 drives the drill barrel 5 to rotate, and the drill barrel 5 cuts the rock at the bottom by rotating. During the cutting process, the first electric telescopic rod 2 pushes the drill barrel 5 to descend, so that the cut rock is stored in the drill barrel 5. After the rock sampling is completed, the push plate 7 is pushed down by the extension of the second electric telescopic rod 4. The push plate 7 slides in the movable groove 6 to push the rock to the bottom of the drill barrel 5 and pressurizes the rock so that the rock can maintain its original layer. The drill barrel 5 is then driven to rise by the first electric telescopic rod 2, and the second electric telescopic rod 4 drives the push plate 7 to push the rock out of the drill barrel 5, thereby completing the discharge of the sample.
