Description

Technical Field

[0001] This utility model relates to the field of geological exploration technology, specifically to a rock and soil geological exploration device for pumped storage power stations. Background Technology

[0002] As a key component of new energy systems, pumped storage power stations are mostly located in mountainous areas with complex topography. These areas have diverse geological structures (including cohesive soil, sand, weathered rock, and intact bedrock), and often have geological features such as fracture zones and fissures. This places extremely high demands on the accuracy, efficiency, and equipment adaptability of rock and soil geological exploration.

[0003] A geological exploration device, disclosed in publication CN 218725491 U, relates to the field of exploration device technology. The device includes a base plate with a side plate mounted on its top. A threaded rod is rotatably mounted inside the side plate, and a slide block is threaded onto the threaded rod. A first motor is mounted on the top of the side plate, with its drive end connected to the top of the threaded rod. A mounting box is slidably connected to the front side of the side plate, and one side of the mounting box is fixedly connected to the slide block. A hollow shaft is rotatably mounted on the bottom wall of the mounting box, and a drill barrel is mounted at the bottom of the hollow shaft. A second motor is mounted on the side wall of the mounting box, with a drive gear mounted on its drive end. A first driven gear is fixedly sleeved on the hollow shaft. This invention enables drilling from shallow to deep, facilitates control of drilling depth, allows sampling of soil at different depths, and facilitates soil sample collection by surveyors.

[0004] However, the above-mentioned device still has some shortcomings in use. The drill barrel and the hollow shaft are mostly fixedly connected, making it impossible to install and disassemble them quickly. When the drill barrel is damaged or needs to be replaced according to different formation characteristics, it is very inconvenient. The disassembly and assembly process is time-consuming and laborious, making it inconvenient to use. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a rock and soil geological exploration device for pumped storage power stations. It solves the problems that drill pipes and hollow shafts are mostly fixedly connected, making it impossible to quickly install and disassemble them. When the drill pipe is damaged or needs to be replaced according to different geological characteristics, it is very inconvenient, and the disassembly and assembly process is time-consuming, labor-intensive, and inconvenient to use.

[0006] This utility model provides the following technical solution: a rock and soil geological exploration device for a pumped storage power station, including a support frame, a lead screw rotatably mounted on the lower surface of the support frame, a connecting plate threaded onto the surface of the lead screw, an installation box fixedly connected to the lower surface of the connecting plate, a connecting pipe rotatably mounted on the lower surface of the installation box, a connecting sleeve fixedly sleeved onto the surface of the connecting pipe, and a drill barrel detachably mounted inside the connecting sleeve.

[0007] Both sides of the connecting sleeve are fixedly connected to connecting boxes. Screws are rotatably installed inside the two connecting boxes. Threaded sleeves are threaded onto the surfaces of the two screws. Fixing plates are fixedly connected to the surfaces of the two threaded sleeves. Multiple locking rods are fixedly connected to the surfaces of the two fixing plates. Multiple locking grooves that match the locking rods are opened on the surfaces of the connecting sleeve and the drill barrel.

[0008] Preferred technical solution 1: A limiting rod is fixedly connected to the lower surface of the support frame, and a slot is opened on the surface of the connecting plate. The connecting plate is slidably sleeved on the limiting rod through the slot.

[0009] Preferred technical solution 2: Slide rods are fixedly connected inside both connecting boxes, and sliding sleeves are slidably fitted onto the surfaces of both slide rods, with the two sliding sleeves respectively fixedly connected to the two fixing plates.

[0010] Preferred technical solution 3: A rotating rod is rotatably installed on the inner top wall of the mounting box. The bottom end of the rotating rod extends into the interior of the drill barrel and is fixedly connected to an auger. A material collection pipe is connected to one side of the drill barrel, and a sealing cap is provided at the bottom end of the material collection pipe.

[0011] Preferred technical solution four: A drive motor is fixedly connected to the side of the mounting box, the output end of the drive motor extends into the interior of the mounting box and is fixedly connected to a first bevel gear, the top end of the connecting tube extends into the interior of the mounting box, and a second bevel gear is fixedly sleeved on the top end of the connecting tube and the surface of the rotating rod, and the first bevel gear and the two second bevel gears mesh with each other.

[0012] Preferred technical solution five: The top end of the lead screw extends to the top of the support frame and is fixedly connected to an operating handle; one end of each of the two screws extends to the outside of the corresponding connecting box and is fixedly connected to an operating disc; the screw and the screw sleeve and the lead screw and the connecting plate meet the self-locking condition; and the thread helix angle is less than the equivalent friction angle.

[0013] Compared with the prior art, this utility model provides a rock and soil geological exploration device for pumped storage power stations, which has the following beneficial effects: In use, the drive motor is first started to drive the first bevel gear to rotate, thereby synchronously driving the connecting pipe and the rotating rod to rotate. The rotation of the connecting pipe drives the connecting sleeve to rotate, which in turn drives the drill barrel to rotate at high speed. Simultaneously, the rotation of the rotating rod drives the auger to rotate synchronously inside the drill barrel. Then, the operator rotates the operating handle extending from the top of the screw to the top of the support frame. The connecting plate moves vertically downwards along the limit rod, causing the mounting box and the drill barrel below to move downwards synchronously, allowing the high-speed rotating drill barrel to gradually cut into the strata. After the strata soil and rock enter the drill barrel, they are transported upwards by the auger to the drill string. At the top of the drill barrel, the material is collected through a collection pipe connected to one side of the drill barrel, enabling geological exploration and sampling of rock and soil. When the drill barrel needs to be disassembled and replaced, simply rotate the two screws in the reverse direction. The screw sleeve will drive the fixed plate on the surface to move away from the connecting sleeve along the sliding rod, thereby causing multiple locking rods to simultaneously disengage from the locking grooves on the surface of the connecting sleeve and the drill barrel. At this point, the drill barrel can be directly removed from the inside of the connecting sleeve. When installing a new drill barrel, simply insert the new drill barrel into the connecting sleeve and rotate the operating disc of the screw in the forward direction to make the locking rods re-lock into the locking grooves to complete the fixation. The entire disassembly and assembly process does not require the removal of multiple bolts or complex parts, which greatly shortens the replacement time of the drill barrel and improves the efficiency of exploration operations.

[0019] Please see Figure 1-4 ,

[0020] Example 1: A rock and soil geological exploration device for a pumped storage power station includes a support frame 1, a lead screw 2 rotatably mounted on the lower surface of the support frame 1, a connecting plate 3 threadedly mounted on the surface of the lead screw 2, an installation box 4 fixedly connected to the lower surface of the connecting plate 3, a connecting pipe 5 rotatably mounted on the lower surface of the installation box 4, a connecting sleeve 6 fixedly sleeved on the surface of the connecting pipe 5, and a drill barrel 7 detachably mounted inside the connecting sleeve 6.

[0021] Both sides of the connecting sleeve 6 are fixedly connected to connecting boxes 8. Both connecting boxes 8 are rotatably installed with screws 9. Both screws 9 are threaded with threaded sleeves 10. Both threaded sleeves 10 are fixedly connected to fixing plates 11. Both fixing plates 11 are fixedly connected to multiple locking rods 12. Both the connecting sleeve 6 and the drill barrel 7 have multiple slots 13 that match the locking rods 12.

[0022] Example 2: The difference between this example and Example 1 is that the lower surface of the support frame 1 is fixedly connected to the limiting rod 14, and the surface of the connecting plate 3 is provided with a slot, through which the connecting plate 3 is slidably sleeved on the limiting rod 14.

[0023] Example 3: The difference between this example and Example 1 is that, in this example, a sliding rod 15 is fixedly connected inside each of the two connecting boxes 8, and a sliding sleeve 16 is slidably sleeved on the surface of each of the two sliding rods 15. The two sliding sleeves 16 are fixedly connected to the two fixing plates 11 respectively.

[0024] Example 4: The difference between this example and Example 1 is that a rotating rod 17 is rotatably installed on the inner top wall of the mounting box 4. The bottom end of the rotating rod 17 extends into the inside of the drill barrel 7 and is fixedly connected to an auger 18. A material collection pipe 19 is connected to one side of the drill barrel 7, and a sealing cap is provided at the bottom end of the material collection pipe 19.

[0025] Example 5: The difference between this example and Example 1 is that a drive motor 20 is fixedly connected to the side of the mounting box 4, the output end of the drive motor 20 extends into the interior of the mounting box 4 and is fixedly connected to a first bevel gear 21, the top end of the connecting tube 5 extends into the interior of the mounting box 4, and a second bevel gear 22 is fixedly sleeved on the top end of the connecting tube 5 and the surface of the rotating rod 17, and the first bevel gear 21 and the two second bevel gears 22 mesh with each other.

[0026] Example 6: The difference between this example and Example 1 is that the top end of the lead screw 2 extends to the top of the support frame 1 and is fixedly connected to an operating handle. One end of each of the two screws 9 extends to the outside of the corresponding connecting box 8 and is fixedly connected to an operating disc. The screws 9 and the screw sleeve 10 and the lead screw 2 and the connecting plate 3 meet the self-locking conditions, and their thread helix angle is less than the equivalent friction angle.

[0027] In summary, when using this pumped-storage power station rock and soil geological exploration device, the drive motor 20 is first started to drive the first bevel gear 21 to rotate, thereby synchronously driving the connecting pipe 5 and the rotating rod 17 to rotate. When the connecting pipe 5 rotates, it drives the connecting sleeve 6 to rotate, which in turn drives the drill barrel 7 to rotate at high speed. At the same time, the rotation of the rotating rod 17 will drive the auger 18 to rotate synchronously inside the drill barrel 7. Then, the operator turns the operating handle that extends from the top of the screw 2 to the support frame 1. The connecting plate 3 will move vertically downward along the limit rod 14, driving the mounting box 4 and the drill barrel 7 below to move downward synchronously. This allows the high-speed rotating drill barrel 7 to gradually cut into the strata. After the strata rock and soil enter the drill barrel 7, they are transported upward by the auger 18 to the upper part of the drill barrel 7, and finally through the drill barrel 7... The side-connected collection pipe 19 collects materials to achieve geological exploration and sampling of rock and soil. When the drill barrel 7 needs to be disassembled and replaced, simply rotate the two screws 9 in the reverse direction. The screw sleeve 10 will drive the fixed plate 11 fixed on the surface to move away from the connecting sleeve 6 along the slide rod 15. This will cause multiple locking rods 12 to simultaneously disengage from the locking grooves 13 on the surface of the connecting sleeve 6 and the drill barrel 7. At this time, the drill barrel 7 can be directly removed from the inside of the connecting sleeve 6. When installing a new drill barrel 7, simply insert the new drill barrel 7 into the connecting sleeve 6 and rotate the operating disc of the screw 9 in the forward direction to make the locking rods 12 re-lock into the locking grooves 13 to complete the fixation. The entire disassembly and assembly process does not require disassembling multiple bolts or complex parts, which greatly shortens the replacement time of the drill barrel 7 and improves the efficiency of exploration operations.
