Description

Technical Field

[0001] This invention relates to the field of geological exploration technology, specifically to a geological exploration device and its exploration method. Background Technology

[0002] Geological surveying refers to the process of systematically studying and evaluating the geological features of the Earth's surface and its subsurface, including rocks, soil, and hydrology, through methods such as on-site investigation, sampling, analysis, and testing. Its main purpose is to obtain information on underground resources, geological structure, and geological hazard risks to support decision-making in engineering construction, resource development, environmental protection, and land use.

[0003] According to announcement number CN111982568B, a geological exploration equipment and method are disclosed, including an engine, a reducer installed at the output end of the engine, a coupling installed at the output end of the reducer, a core tube installed on the coupling, and a drill bit threadedly connected to the core tube. Guide tubes are fixedly installed on both sides of the engine, a guide rod is slidably installed in the guide tube, and a positioning ring is slidably installed on the guide rod.

[0004] The above technical solution, by limiting the distance the guide tube can move through the positioning ring, allows workers to easily control the feed depth of the drill bit, improving the survey results. However, this solution can only control the depth of the drill bit's descent and cannot achieve drill pipe splicing. When conducting deep geological surveys, if the length of a single drill pipe is insufficient to reach the target survey depth, frequent machine stops and manual splicing of the drill pipe are required. This not only significantly prolongs the survey operation time and reduces work efficiency, but also, during manual splicing, improper operation may lead to low drill pipe docking accuracy, affecting the stability of drilling and the integrity of core samples, increasing survey costs and operational risks.

[0010] Preferably, the inner wall of the frame is slidably connected to a positioning post, and the bottom end of the positioning post is slidably connected to the inner wall of the base plate.

[0011] Preferably, four mounting blocks are fixedly connected to the outer surface of the base plate, and each mounting block has a mounting hole on its upper surface.

[0014] Preferably, a lever is fixedly connected to the right end of the second screw, and the outer surface of the lever is provided with anti-slip grooves arranged at equal intervals.

[0015] A geological survey method using geological survey equipment specifically includes the following steps: S1: When in use, first connect the servo motor, drilling rig power motor, electric push rod and electromagnet to the external power supply. Then start the drilling rig power motor. Its power output end drives the rotating shaft and rotating block to rotate through the differential. The rotating block drives the main core tube and drill bit fixed to it to rotate synchronously. Then start the servo motor. The servo motor drives the first screw to rotate. Since the first screw is threadedly connected to the lifting plate and the lifting plate cannot rotate under the restriction of the guide column, the lifting plate will move downward along the first screw and guide column, thereby driving the rotating block, main core tube and rotating drill bit to move downward. The drill bit begins to drill into the geological layer, and the core sample is collected inside the main core tube. S2: When the length of the main core tube is insufficient to reach the target exploration depth, the core tubes need to be spliced. The electromagnet is energized, and the electromagnet generates magnetic force to attract the docking column, causing the docking column to overcome the elastic force of the strong spring and slide into the rotating block until the docking column is disengaged from the slot on the inner wall of the main core tube. The fixed connection between the rotating block and the main core tube is released. Then, the servo motor is controlled to reverse, so that the lifting plate drives the rotating block to rise to a position higher than the frame. S3: At this point, by pushing the frame along the inner wall of the base plate towards the top of the main core tube, the limiting plate and limiting rollers inside the frame limit and guide the spliced ​​core tube, preventing it from tipping over during movement. When the left side of the frame contacts the right side of the positioning baffle, the frame stops moving. At this point, the spliced ​​core tube is directly above the main core tube. Then, the operator rotates the lever, which drives the second screw to rotate. The second screw is threadedly connected to the limiting push plate. Since the outer surface of the limiting push plate is slidably connected to the inner wall of the frame, the limiting push plate will slide to the left along the inner wall of the frame, pushing the leftmost spliced ​​core tube towards the top of the main core tube and being blocked by the limiting frame and positioning baffle. The central axis of this spliced ​​core tube coincides with the central axis of the main core tube, and the central axis of the rotating block is on the same straight line. At this point, the limiting push plate stops moving, completing the precise positioning of the spliced ​​core tube so that the rotating block can be accurately inserted into the spliced ​​core tube for fixing. S4: Then, control the rotating block to descend and insert it into the spliced ​​core tube. Turn off the electromagnet. At this time, the powerful spring releases its elastic potential energy, pushing the docking post into the corresponding groove on the inner wall of the spliced ​​core tube, realizing the rapid fixing of the rotating block and the spliced ​​core tube. Then, start the servo motor to rotate forward again, driving the spliced ​​core tube to descend, so that the L-shaped splicing block at its bottom end aligns with the L-shaped splicing groove at the top of the main core tube below and is inserted. At the same time, the drilling rig's power motor drives the rotating block to rotate the spliced ​​core tube clockwise, so that the extension block of the L-shaped splicing block is inserted into the transverse extension section of the L-shaped splicing groove, completing the splicing of the main core tube and the spliced ​​core tube. After the splicing of one spliced ​​core tube is completed, start the electric push rod, so that its telescopic end drives the limit frame away from the enclosure. The frame is moved in a certain direction to prevent the limiting frame from colliding with the spliced ​​core tubes when the frame is reset. Then, the frame is pushed along the inner wall of the base plate to reset away from the main core tube. After reset, the electric push rod is reset, and the limiting frame returns to its original position under the action of the electric push rod. The remaining spliced ​​core tubes in the frame are re-limited to prevent them from moving in the working state. Finally, the positioning post is inserted into the base plate for limiting. Then, the servo motor is controlled to rotate forward to make the spliced ​​core tubes descend as a whole. The drill bit continues to drill, and the core sample enters the main core tube and the spliced ​​core tubes in sequence. If it is necessary to further deepen the exploration depth, the above splicing steps can be repeated to splice more core tubes in sequence.

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are: First, this invention, by incorporating a splicing mechanism, utilizes the magnetic properties of an electromagnet to attract and extract the docking post from the inner wall of the main core tube, releasing the main core tube from its fixation. Simultaneously, a servo motor drives the first screw to rotate, causing the lifting plate and rotating block to rise. This detaches the rotating block from the main core tube, transporting the spliced ​​core tube to a designated position. When the rotating block is inserted into the spliced ​​core tube, the electromagnet is deactivated. At this point, a powerful spring releases its elastic potential energy, pushing the docking post into the corresponding groove on the inner wall of the spliced ​​core tube, achieving rapid bonding between the rotating block and the spliced ​​core tube. Simultaneously, in conjunction with the servo motor and drilling rig power motor, the lowering and rotation of the spliced ​​core tube are controlled, allowing the L-shaped splicing block at the bottom of the spliced ​​core tube to be inserted into the L-shaped splicing groove at the top of the main core tube below or the already spliced ​​core tube. With the instantaneous rotation of the clock hand, the extension block of the L-shaped splicing block is inserted into the transverse extension section of the L-shaped splicing groove, which can drive the spliced ​​core tube to rise, fall and rotate, effectively realizing the rapid splicing of the core tube without manual operation, greatly shortening the splicing time and improving the work efficiency of deep geological exploration.

[0017] Secondly, this invention, by providing a pushing mechanism, can use the frame to push the internal spliced ​​core tubes to move directly above the main core tube or the already spliced ​​core tube until they are blocked by the positioning baffle, so that the frame reaches the designated position. At the same time, the rotation of the second screw drives the limiting push plate to slide along the inner wall of the frame. The limiting push plate can push the internal spliced ​​core tubes to move to the leftmost side of the frame, where they are blocked by the limiting frame and the positioning baffle. At this time, the central axis of the spliced ​​core tube is on the same straight line as the central axis of the main core tube or the already spliced ​​core tube and the rotating block, ensuring the precise alignment of the upper and lower core tubes during splicing, thus improving splicing accuracy and efficiency.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0021] Please see Figure 1-8 The system includes a base plate 1, a splicing mechanism 2 and a pushing mechanism 3, both located above the base plate 1. The splicing mechanism 2 includes a fixing frame 201, the bottom surface of which is fixedly connected to the upper surface of the base plate 1. A servo motor 202 is fixedly connected to the inner top wall of the fixing frame 201. A first screw 203 is fixedly connected to the output end of the servo motor 202. The bottom end of the first screw 203 is rotatably connected to the inner wall of the base plate 1, and the outer surface of the first screw 203 is threaded. There is a lifting plate 204, and a drilling rig power motor 206 is fixedly connected to the upper surface of the lifting plate 204. A differential 207 is fixedly connected to the output end of the drilling rig power motor 206. The upper surface of the differential 207 is fixedly connected to the bottom surface of the lifting plate 204. A rotating shaft 208 is fixedly connected to the output end of the differential 207. A rotating block 211 is fixedly connected to the bottom end of the rotating shaft 208. A main core tube 209 is slidably connected to the outer surface of the rotating block 211. A base plate 1 is provided above the base plate 1. Several spliced ​​core tubes 205, a main core tube 209, and four L-shaped splicing grooves 212 are formed on the upper surface of each spliced ​​core tube 205. An electromagnet 214 is fixedly connected to the inner wall of the rotating block 211. Eight docking posts 216 are slidably connected to the inner wall of the rotating block 211. The outer surface of each docking post 216 is slidably connected to the inner wall of the main core tube 209. A stabilizing plate 215 is slidably connected to the outer surface of each docking post 216. The outer surface of each stabilizing plate 215 is... The inner wall of the rotating block 211 is fixedly connected. Each docking column 216 is fixedly connected to a strong spring 217 on the side near the stabilizing plate 215. The end of each strong spring 217 near the stabilizing plate 215 is fixedly connected to the side of the stabilizing plate 215 away from the electromagnet 214. The bottom end of each splicing core tube 205 is fixedly connected to four L-shaped splicing blocks 213. By setting the splicing mechanism 2, rapid splicing and disassembly can be achieved to adapt to the geological exploration needs at different depths.

[0022] A drill bit 210 is installed below the base plate 1. The upper surface of the drill bit 210 is fixedly connected to the bottom surface of the main core tube 209. The drill bit 210 can efficiently drill into the geological layer. Its sharp cutting edge design can quickly break up geological structures such as rocks and soil, and work with the main core tube 209 to collect core samples.

[0023] Four mounting blocks 4 are fixedly connected to the outer surface of the base plate 1. Each mounting block 4 has a mounting hole 5 on its upper surface. The base plate 1 can be securely installed on the surveying platform or mobile equipment through the mounting blocks 4 and mounting holes 5, ensuring that the equipment will not shake or shift during drilling, and providing stable foundation support for the entire surveying work.

[0024] The inner wall of the fixed frame 201 is fixedly connected to two reinforcing blocks 6. The bottom surface of each reinforcing block 6 is fixedly connected to the upper surface of the base plate 1. The reinforcing blocks 6 can further enhance the connection strength between the fixed frame 201 and the base plate 1, and disperse the stress generated by the fixed frame 201 when bearing the weight of components such as the servo motor 202 and the lifting plate 204, so as to avoid the fixed frame 201 from deforming or being damaged due to long-term stress and extend the service life of the equipment.

[0025] Two guide posts 7 are slidably connected to the inner wall of the lifting plate 204. The bottom end of each guide post 7 is fixedly connected to the upper surface of the base plate 1. The guide posts 7 can accurately guide the lifting movement of the lifting plate 204, preventing the lifting plate 204 from rotating or deviating under the drive of the first screw 203, ensuring that the lifting plate 204 always maintains a stable vertical movement, thereby ensuring the coaxiality of the rotating block 211, the main core tube 209, and the splicing core tube 205 during drilling and splicing, improving the stability of drilling and splicing.

[0026] The specific implementation of this embodiment is as follows: In use, firstly, the servo motor 202, the drilling rig power motor 206, and the electromagnet 214 are connected to an external power source. Then, the drilling rig power motor 206 is started, and its power output terminal drives the rotating shaft 208 and the rotating block 211 to rotate through the differential 207. The rotating block 211 then drives the main core tube 209 and the drill bit 210 fixed thereto to rotate synchronously. Next, the servo motor 202 is started, and the servo motor 202 drives the first screw 203 to rotate. Since the first screw 203 is threadedly connected to the lifting plate 204, and the lifting plate 204 cannot rotate under the restriction of the guide post 7, the lifting plate 204 will rotate along the first screw 203 and the guide post 7. The column 7 moves downwards, which in turn drives the rotating block 211, the main core tube 209, and the rotating drill bit 210 downwards. The drill bit 210 begins drilling into the geological layer, and the core sample is collected inside the main core tube 209. When the length of the main core tube 209 is insufficient to reach the target exploration depth, the core tubes need to be spliced. The electromagnet 214 is energized, and the electromagnet 214 generates magnetic force to attract the docking column 216, causing the docking column 216 to overcome the elastic force of the strong spring 217 and slide into the rotating block 211 until the docking column 216 disengages from the slot on the inner wall of the main core tube 209, releasing the fixed connection between the rotating block 211 and the main core tube 209. Then, the servo motor is controlled. The machine 202 reverses, causing the lifting plate 204 to lift the rotating block 211 to a position higher than the frame 301. At this time, the pushing mechanism 3 starts working, pushing the frame 301 along the inner wall of the base plate 1 towards the top of the main core tube 209. Then, the rotating block 211 is lowered and inserted into the splicing core tube 205. The electromagnet 214 is turned off, and the strong spring 217 releases its elastic potential energy, pushing the docking post 216 into the corresponding groove on the inner wall of the splicing core tube 205, thus quickly fixing the rotating block 211 to the splicing core tube 205. Then, the servo motor 202 is restarted to rotate forward, driving the splicing core tube 205 to descend, aligning the L-shaped splicing block 213 at its bottom with the bottom. The L-shaped splicing groove 212 at the top of the main core tube 209 is inserted, and at the same time, the drilling rig power motor 206 drives the rotating block 211 to rotate the spliced ​​core tube 205 clockwise, so that the extension block of the L-shaped splicing block 213 is inserted into the transverse extension groove of the L-shaped splicing groove 212, completing the splicing of the main core tube 209 and the spliced ​​core tube 205. Then, the servo motor 202 is controlled to rotate forward, so that the spliced ​​core tube is lowered as a whole, and the drill bit 210 continues to drill. The core sample enters the main core tube 209 and the spliced ​​core tube 205 in sequence. If it is necessary to further deepen the exploration depth, the above splicing steps can be repeated to splice more spliced ​​core tubes 205 in sequence. Example

[0027] Please see Figure 1-8The pushing mechanism 3 includes a frame 301, the outer surface of which is slidably connected to the inner wall of the base plate 1. Several limiting plates 305 are fixedly connected to the inner wall of the frame 301, and several limiting rollers 306 are rotatably connected to the inner wall of each limiting plate 305. A positioning baffle 302 is fixedly connected to the upper surface of the base plate 1, and the right side of the positioning baffle 302 contacts the outer surface of the main core tube 209. A fixing plate 307 is fixedly connected to the outer surface of the frame 301, and the fixing plate 307 is close to the frame 301. An electric push rod 308 is fixedly connected to one side. The telescopic end of the electric push rod 308 is fixedly connected to a limiting frame 309. The outer surface of the limiting frame 309 is slidably connected to the inner wall of the fixing plate 307. A second screw 303 is fixedly connected to the outer surface of the frame 301. A limiting push plate 304 is threadedly connected to the outer surface of the second screw 303. The outer surface of the limiting push plate 304 is slidably connected to the inner wall of the frame 301. By setting the pushing mechanism 3, the spliced ​​pipe can be pushed to the designated position, thereby improving the accuracy of splicing.

[0028] The inner wall of the frame 301 is slidably connected with a positioning post 310. The bottom end of the positioning post 310 is slidably connected to the inner wall of the base plate 1. The positioning post 310 can cooperate with the sliding groove of the inner wall of the base plate 1 to strictly limit the sliding direction of the frame 301 and prevent the frame 301 from shifting when placed.

[0029] The right end of the second screw 303 is fixedly connected to a lever 8. The outer surface of the lever 8 is provided with anti-slip grooves 9 arranged at equal intervals. The lever 8 is designed to facilitate the operator to manually rotate the second screw 303, while the anti-slip grooves 9 can effectively increase the friction between the hand and the lever 8, and prevent slippage during rotation, so that the operator can adjust the position of the limit push plate 304 more effortlessly and stably.

[0030] The specific implementation method of this embodiment is as follows: In use, first connect the electric push rod 308 to an external power source. Then, the operator can sequentially place several spliced ​​core tubes 205 into the frame 301. During splicing, the frame 301 is pushed along the inner wall of the base plate 1 towards the top of the main core tube 209. The limiting plate 305 and limiting roller 306 inside the frame 301 limit and guide the spliced ​​core tubes 205, preventing them from tipping over during movement. When the left side of the frame 301 is aligned with the positioning baffle 30... When the right side of core tube 205 contacts the main core tube 209, the frame 301 stops moving. At this time, the spliced ​​core tube 205 is directly above the main core tube 209. Then, the operator rotates the lever 8, which drives the second screw 303 to rotate. The second screw 303 is threadedly connected to the limiting push plate 304. Since the outer surface of the limiting push plate 304 is slidably connected to the inner wall of the frame 301, the limiting push plate 304 will slide to the left along the inner wall of the frame 301, pushing the leftmost spliced ​​core tube 205 to move directly above the main core tube 209. The core tube 205 is obscured by the limiting frame 309 and the positioning baffle 302. The central axis of the spliced ​​core tube 205 coincides with the central axis of the main core tube 209, and the central axis of the rotating block 211 is on the same straight line. At this time, the limiting push plate 304 stops moving, completing the precise positioning of the spliced ​​core tube 205 so that the rotating block 211 can be accurately inserted into the spliced ​​core tube 205 for fixation. After the splicing of one core tube 205 is completed, the electric push rod 308 is activated, causing its telescopic end to drive the limiting frame 309 away from the frame 3. The movement in the direction of 01 can prevent the limiting frame 309 from colliding with the spliced ​​core tube 205 when the frame 301 is reset. Then, the frame 301 is pushed to reset along the inner wall of the bottom plate 1 in a direction away from the main core tube 209. After reset, the electric push rod 308 is reset, and the limiting frame 309 returns to its original position under the action of the electric push rod 308. The remaining spliced ​​core tube 205 in the frame 301 is re-limited to prevent it from moving in the working state. Finally, the positioning column 310 is inserted into the bottom plate 1 for limiting.

[0031] The working principle of this invention is as follows: In use, firstly, the servo motor 202, the drilling rig power motor 206, the electric push rod 308, and the electromagnet 214 are connected to an external power source. Then, the drilling rig power motor 206 is started, and its power output end drives the rotating shaft 208 and the rotating block 211 to rotate through the differential 207. The rotating block 211 drives the main core tube 209 and the drill bit 210 fixed thereto to rotate synchronously. Next, the servo motor 202 is started, and the servo motor 202 drives the first screw 203 to rotate. Since the first screw 203 is threadedly connected to the lifting plate 204, and the lifting plate 204 cannot rotate under the restriction of the guide post 7, the lifting plate 204 will move downward along the first screw 203 and the guide post 7, thereby driving the rotating block 211, the main core tube 209, and the rotating drill bit 210 to move downward. The drill bit 210 begins to drill into the geological layer, and the core sample is collected inside the main core tube 209. When the length of the main core tube 209 is insufficient to reach the target exploration depth, the core tubes need to be spliced. When the electromagnet 214 is energized, the electromagnet 214 generates magnetic force to attract the docking post 216, causing the docking post 216 to overcome the elastic force of the strong spring 217 and slide into the rotating block 211 until the docking post 216 disengages from the slot in the inner wall of the main core tube 209, releasing the fixed connection between the rotating block 211 and the main core tube 209. Then, the servo motor 202 is controlled to reverse, causing the lifting plate 204 to drive the rotating block 211 to rise to a position higher than the frame 301. At this time, by pushing the frame 301 along the inner wall of the base plate 1 towards the top of the main core tube 209, the limiting plate 305 and the limiting roller 306 inside the frame 301 limit and guide the spliced ​​core tube 205, preventing it from tipping over during movement. When the left side of the frame 301 contacts the right side of the positioning baffle 302, the frame 301 stops moving. At this time, the spliced ​​core tube 205 is directly above the main core tube 209. Then, the operator rotates the lever 8, which drives the second screw 303 to rotate. The second screw 303 is threadedly connected to the limiting push plate 304. The outer surface of 304 is slidably connected to the inner wall of the frame 301, so the limiting push plate 304 will slide to the left along the inner wall of the frame 301, pushing the leftmost spliced ​​core tube 205 to move directly above the main core tube 209 and be blocked by the limiting frame 309 and the positioning baffle 302. The central axis of the spliced ​​core tube 205 coincides with the central axis of the main core tube 209, and the central axis of the rotating block 211 is on the same straight line. At this time, the limiting push plate 304 stops moving, completing the precise positioning of the spliced ​​core tube 205 so that the rotating block 211 can be accurately inserted into the spliced ​​core tube 205 for fixing. Then, the rotating block 211 is lowered and inserted into the spliced ​​core tube 205. The electromagnet 214 is turned off, and the powerful spring 217 releases its elastic potential energy, pushing the docking post 216 into the corresponding groove on the inner wall of the spliced ​​core tube 205, thus quickly fixing the rotating block 211 to the spliced ​​core tube 205. Next, the servo motor 202 is restarted to rotate forward, driving the spliced ​​core tube 205 to descend, so that the L-shaped splicing block 213 at its bottom end aligns with the L-shaped splicing groove 212 at the top of the main core tube 209 below and is inserted. At the same time, the drilling rig power motor 206 drives the rotating block 211 to rotate the spliced ​​core tube 205 clockwise, so that the extension block of the L-shaped splicing block 213 is inserted into the transverse extension section of the L-shaped splicing groove 212, completing the splicing of the main core tube 209 and the spliced ​​core tube 205. After the splicing of one spliced ​​core tube 205 is completed, the electric push rod 308 is started, so that its telescopic end drives the limit frame. Moving 309 away from the frame 301 prevents the limiting frame 309 from colliding with the spliced ​​core tube 205 when the frame 301 is reset. Then, the frame 301 is pushed along the inner wall of the base plate 1 away from the main core tube 209. After reset, the electric push rod 308 is reset, and the limiting frame 309 returns to its original position under the action of the electric push rod 308. The remaining spliced ​​core tubes 205 in the frame 301 are re-limited to prevent them from moving in the working state. Finally, the positioning post 310 is inserted into the base plate 1 for limiting. Then, the servo motor 202 is controlled to rotate forward, so that the spliced ​​core tube is lowered as a whole. The drill bit 210 continues to drill, and the core sample enters the main core tube 209 and the spliced ​​core tube 205 in sequence. If it is necessary to further deepen the exploration depth, the above splicing steps can be repeated to splice more spliced ​​core tubes 205 in sequence.

[0032] A geological survey method using geological survey equipment specifically includes the following steps: S1: In use, first connect the servo motor 202, the drilling rig power motor 206, the electric push rod 308 and the electromagnet 214 to the external power supply. Then start the drilling rig power motor 206. Its power output end drives the rotating shaft 208 and the rotating block 211 to rotate through the differential 207. The rotating block 211 drives the main core tube 209 and the drill bit 210 fixed thereto to rotate synchronously. Then start the servo motor 202. The servo motor 202 drives the first screw 203 to rotate. Since the first screw 203 is threadedly connected to the lifting plate 204 and the lifting plate 204 cannot rotate under the restriction of the guide post 7, the lifting plate 204 will move downward along the first screw 203 and the guide post 7, thereby driving the rotating block 211, the main core tube 209 and the rotating drill bit 210 to move downward. The drill bit 210 begins to drill into the geological layer, and the core sample is collected inside the main core tube 209. S2: When the length of the main core tube 209 is insufficient to reach the target exploration depth, the core tubes need to be spliced. The electromagnet 214 is energized, and the electromagnet 214 generates magnetic force to attract the docking post 216, so that the docking post 216 overcomes the elastic force of the strong spring 217 and slides into the rotating block 211 until the docking post 216 disengages from the slot in the inner wall of the main core tube 209, and the fixed connection between the rotating block 211 and the main core tube 209 is released. Then, the servo motor 202 is controlled to reverse, so that the lifting plate 204 drives the rotating block 211 to rise to a position higher than the frame 301. S3: At this time, by pushing the frame 301 along the inner wall of the base plate 1 towards the top of the main core tube 209, the limiting plate 305 and limiting roller 306 inside the frame 301 limit and guide the spliced ​​core tube 205, preventing it from tipping over during movement. When the left side of the frame 301 contacts the right side of the positioning baffle 302, the frame 301 stops moving. At this time, the spliced ​​core tube 205 is directly above the main core tube 209. Then, the operator rotates the lever 8, which drives the second screw 303 to rotate. The second screw 303 is threadedly connected to the limiting push plate 304. Due to the limiting... The outer surface of the push plate 304 is slidably connected to the inner wall of the frame 301, so the limiting push plate 304 will slide to the left along the inner wall of the frame 301, pushing the leftmost spliced ​​core tube 205 to move directly above the main core tube 209, and is blocked by the limiting frame 309 and the positioning baffle 302. The central axis of the spliced ​​core tube 205 coincides with the central axis of the main core tube 209, and the central axis of the rotating block 211 is on the same straight line. At this time, the limiting push plate 304 stops moving, completing the precise positioning of the spliced ​​core tube 205, so that the rotating block 211 can be accurately inserted into the spliced ​​core tube 205 for fixing. S4: Then, control the rotating block 211 to descend and insert into the spliced ​​core tube 205, turn off the electromagnet 214, at this time the strong spring 217 releases elastic potential energy, pushing the docking post 216 to insert into the corresponding groove on the inner wall of the spliced ​​core tube 205, realizing the rapid fixation of the rotating block 211 and the spliced ​​core tube 205. Then, start the servo motor 202 to rotate forward again, driving the spliced ​​core tube 205 to descend, so that the L-shaped splicing block 213 at its bottom is aligned with the bottom. The L-shaped splicing slot 212 at the top of the main core tube 209 is inserted, and at the same time, the drilling rig's power motor 206 drives the rotating block 211 to rotate the spliced ​​core tube 205 clockwise, so that the extension block of the L-shaped splicing block 213 is inserted into the transverse extension section of the L-shaped splicing slot 212, completing the splicing of the main core tube 209 and the spliced ​​core tube 205. After the splicing of one spliced ​​core tube 205 is completed, the electric push rod 308 is activated, causing its telescopic end to move to the limit position. The frame 309 moves away from the enclosure 301 to avoid collision between the limiting frame 309 and the spliced ​​core tube 205 when the enclosure 301 is reset. Then, the enclosure 301 is pushed along the inner wall of the base plate 1 away from the main core tube 209 to reset. After reset, the electric push rod 308 is reset, and the limiting frame 309 returns to its original position under the action of the electric push rod 308. The remaining spliced ​​core tubes 205 in the enclosure 301 are re-limited to prevent them from moving in the working state. Finally, the positioning column 310 is inserted into the base plate 1 for limiting. Then, the servo motor 202 is controlled to rotate forward to make the spliced ​​core tube descend as a whole. The drill bit 210 continues to drill. The core sample enters the main core tube 209 and the spliced ​​core tube 205 in sequence. If it is necessary to further deepen the exploration depth, the above splicing steps can be repeated to splice more spliced ​​core tubes 205 in sequence.

10. A geological surveying method using a geological surveying equipment according to any one of claims 1-9, characterized in that: Specifically, the following steps are included: S1: In use, first connect the servo motor (202), drilling rig power motor (206), electric push rod (308), and electromagnet (214) to the external power supply. Then start the drilling rig power motor (206), whose power output end drives the rotating shaft (208) and rotating block (211) to rotate through the differential (207). The rotating block (211) drives the main core tube (209) and drill bit (210) fixed thereto to rotate synchronously. Then start the servo motor (202), the servo motor (202) drives the main core tube (209) and drill bit (210) to rotate synchronously. The first screw (203) rotates. Since the first screw (203) is threadedly connected to the lifting plate (204) and the lifting plate (204) cannot rotate due to the restriction of the guide post (7), the lifting plate (204) will move downward along the first screw (203) and the guide post (7), thereby driving the rotating block (211), the main core tube (209) and the rotating drill bit (210) to move downward. The drill bit (210) begins to drill into the geological layer, and the core sample is collected inside the main core tube (209). S2: When the length of the main core tube (209) is insufficient to reach the target exploration depth, the core tubes need to be spliced. The electromagnet (214) is energized, and the electromagnet (214) generates magnetic force to attract the docking column (216), so that the docking column (216) overcomes the elastic force of the strong spring (217) and slides into the rotating block (211) until the docking column (216) is separated from the slot of the inner wall of the main core tube (209), and the fixed connection between the rotating block (211) and the main core tube (209) is released. Then, the servo motor (202) is controlled to reverse, so that the lifting plate (204) drives the rotating block (211) to rise to a position higher than the frame (301). S3: At this time, by pushing the frame (301) along the inner wall of the base plate (1) towards the top of the main core tube (209), the limiting plate (305) and limiting roller (306) inside the frame (301) limit and guide the spliced ​​core tube (205) to prevent it from tipping over during movement. When the left side of the frame (301) contacts the right side of the positioning baffle (302), the frame (301) stops moving. At this time, the spliced ​​core tube (205) is located directly above the main core tube (209). Then the operator rotates the lever (8), which drives the second screw (303) to rotate. The second screw (303) is threadedly connected to the limiting push plate (304). The outer surface of the limiting push plate (304) is slidably connected to the inner wall of the frame (301), so the limiting push plate (304) will slide to the left along the inner wall of the frame (301), pushing the leftmost spliced ​​core tube (205) to move directly above the main core tube (209) and be blocked by the limiting frame (309) and the positioning baffle (302). The central axis of the spliced ​​core tube (205) coincides with the central axis of the main core tube (209), and the central axis of the rotating block (211) is on the same straight line. At this time, the limiting push plate (304) stops moving, completing the precise positioning of the spliced ​​core tube (205) so that the rotating block (211) can be accurately inserted into the spliced ​​core tube (205) for fixing. S4: Then control the rotating block (211) to descend and insert into the spliced ​​core tube (205), turn off the electromagnet (214), at this time the strong spring (217) releases elastic potential energy, pushing the docking post (216) to insert into the corresponding groove on the inner wall of the spliced ​​core tube (205), realizing the rapid fixing of the rotating block (211) and the spliced ​​core tube (205). Then start the servo motor (202) to rotate forward again, driving the spliced ​​core tube (205) to descend, so that the L-shaped splicing block (213) at its bottom is aligned with the lower part. The L-shaped splicing groove (212) at the top of the main core tube (209) is inserted, and at the same time, the drilling rig power motor (206) drives the rotating block (211) to rotate the spliced ​​core tube (205) clockwise, so that the extension block of the L-shaped splicing block (213) is inserted into the transverse extension groove of the L-shaped splicing groove (212), thus completing the splicing of the main core tube (209) and the spliced ​​core tube (205). After the splicing of one spliced ​​core tube (205) is completed, the electric push rod (308) is started, so that its telescopic end drives the main core tube (209) to rotate. The limiting frame (309) moves away from the enclosure frame (301) to avoid collision between the limiting frame (309) and the spliced ​​core tube (205) when the enclosure frame (301) is reset. Then, the enclosure frame (301) is pushed to reset along the inner wall of the base plate (1) away from the main core tube (209). After reset, the electric push rod (308) is reset, and the limiting frame (309) returns to its original position under the action of the electric push rod (308). This resets the remaining spliced ​​core tube (205) inside the enclosure frame (301). Re-limit the position to prevent it from moving while in operation. Finally, insert the positioning post (310) into the bottom plate (1) for limiting. Then, continue to control the servo motor (202) to rotate forward, so that the spliced ​​core tube descends as a whole. The drill bit (210) continues to drill. The core sample enters the main core tube (209) and the spliced ​​core tube (205) in sequence. If it is necessary to further deepen the exploration depth, the above splicing steps can be repeated to splice more spliced ​​core tubes (205) in sequence.
