[0024] Please see Figure 1-4 The present invention provides an embodiment of a core sampling device for quality testing of water conservancy projects that is easy to locate, comprising a base 1, characterized in that: an engine 2 is provided at the top of the front end of the base 1, a drill bit 3 is fixedly connected below the engine 2, and two sets of positioning components are fixedly connected at the top of the base 1.
[0025] Please see Figure 1-4A core sampling device for quality testing of water conservancy projects with easy positioning also includes an easy positioning component. The easy positioning component includes a guide post 4, which is fixedly connected to the top of the base 1. A crossbeam 5 is fixedly connected to the top of the guide post 4. A rotating wheel 6 is set at the top of the crossbeam 5. A first lead screw 7 is fixedly connected to the bottom of the rotating wheel 6. A movable platform 8 is movably connected to the front end of the guide post 4. A second lead screw 9 is fixedly connected to the middle position inside the movable platform 8. Guide rods 10 are fixedly connected to the upper and lower ends inside the movable platform 8. A platform 11 is movably connected to the front end of the movable platform 8. An engine 2 is fixedly connected to the platform 11. The first lead screw 7 passes through the crossbeam 5 and is connected to the movable platform 8. The platform 11 is connected to the second lead screw 9 and the guide rods 10. The first lead screw 7 is aligned with the vertical center line of the crossbeam 5. The platform 11 can move left and right along the front end of the movable platform 8. The movable platform 8 can move up and down along the guide post 4 for easy positioning.
[0026] Specifically, such as Figure 1 and Figure 2 As shown, during use, rotating the wheel 6 drives the first lead screw 7 at the bottom to rotate. While the first lead screw 7 rotates, it drives the moving platform 8 to move up and down. After determining the up and down position, the left and right movement direction of the equipment can also be adjusted. After starting the motor, the second lead screw 9 can be rotated. During the rotation of the second lead screw 9, the platform 11 is driven to move left and right along the guide rod 10, which can drive the engine 2 and drill bit 3 fixed on the platform 11 to move left and right. It is convenient to use and has high positioning efficiency. Because the orientation adjustment relies on the machine, the positioning accuracy is also improved, and positioning is convenient.
[0027] A first vertical box 12 is fixedly connected to the right side of the front end of the base 1. A first folding plate 13 is movably connected inside the first vertical box 12. An iron block 14 is fixedly connected to the front end of the first folding plate 13. A second vertical box 15 is fixedly connected to the left side of the front end of the base 1. A second folding plate 16 is movably connected inside the second vertical box 15. A magnet 17 is fixedly connected to the front end of the second folding plate 16. The internal shape and size of the first folding plate 13 are the same as the internal shape and size of the first vertical box 12. The first folding plate 13 can be pulled back and forth along the inside of the first vertical box 12. The internal shape and size of the second folding plate 16 are the same as the internal shape and size of the second vertical box 15. The second folding plate 16 can be pulled back and forth along the inside of the second vertical box 15 to prevent splashing.
[0028] Specifically, such as Figure 1 and Figure 3As shown, during use, mud and rocks are easily ejected when the drill bit 3 drills downwards. To avoid injuring workers and causing environmental pollution after the ejection, the second folding plate 16 can be pulled out from the second vertical box 15, and the first folding plate 13 can be pulled out from the first vertical box 12. Then, the magnet 17 and the iron block 14 are attached to each other and fixedly connected, so that the second folding plate 16 and the first folding plate 13 surround the front end of the drill bit 3 to protect the excavation area and prevent damage caused by the ejection.
[0029] The front end of the guide post 4 is fixedly connected to multiple sets of scales 18. The bottom end of the guide post 4 is movably connected to a sleeve 19. The sleeve 19 has an internal threaded hole 20. A screw 21 is installed inside the internal threaded hole 20. The internal thread shape of the internal threaded hole 20 matches the external thread shape of the screw 21. The internal shape and size of the sleeve 19 are consistent with the external shape and size of the guide post 4. The sleeve 19 can move up and down along the outside of the guide post 4, which can limit the vertical height.
[0030] Specifically, such as Figure 1 and Figure 4 As shown, when in use, the required excavation depth can be set according to the scale 18, and then the sleeve 19 can be moved up. Then, the screw 21 can be screwed into the internal thread hole 20 and tightly fitted with the guide post 4. At this time, the position of the sleeve 19 and the guide post 4 is fixed, and the descent range of the moving table 8 is also fixed, which makes it convenient to adjust the height limit, and also makes the core sampling depth more accurate, the scale precise, and the upper and lower positions controllable.
[0031] Working Principle: In use, the rotating wheel 6 drives the first lead screw 7 at the bottom to rotate. Simultaneously, the rotating lead screw 7 moves the moving platform 8 up and down. After determining the vertical position, the horizontal movement direction can be adjusted. Starting the motor causes the second lead screw 9 to rotate, which in turn moves the platform 11 along the guide rod 10, thus moving the engine 2 and drill bit 3 fixed on the platform 11 horizontally. This design is convenient and efficient in positioning. Because the orientation is adjusted by the machine, the positioning accuracy is also improved. However, during drilling, the drill bit 3 may eject mud and rocks. To prevent this, [further details are needed]. To prevent injury to workers and environmental pollution, the second folding plate 16 can be pulled out from the second vertical box 15, and the first folding plate 13 can be pulled out from the first vertical box 12. Then, the magnet 17 and the iron block 14 are attached to each other and fixedly connected, so that the second folding plate 16 and the first folding plate 13 surround the front end of the drill bit 3 to protect the excavation area. When in use, the required excavation depth can be set according to the scale 18, and then the sleeve 19 can be moved up. Then, the screw 21 can be screwed into the internal thread hole 20 and tightly attached to the guide post 4. At this time, the position of the sleeve 19 and the guide post 4 is fixed, and the descent range of the moving table 8 is also fixed, which makes it convenient to adjust the height limit and makes the core sampling depth more accurate.
