Description

Technical Field

[0001] This invention relates to the field of geothermal drilling exploration technology, specifically to an exploration and sampling device for geothermal drilling and its usage method. Background Technology

[0002] When conducting soil exploration and sampling in soft, damp, or uneven surface environments in the field, portable drilling equipment is often required. Traditional equipment often relies on manual fixing or simple supports, which are prone to tilting, displacement, or subsidence under such geological conditions, leading to sampling deviations or even equipment damage.

[0003] In existing technologies, some exploration devices use fixed bases or ground stakes for stability, but their expansion range is limited, they cannot adapt to the support requirements of different spans, and they lack cleaning capabilities, requiring manual cleaning of the poles after each sampling, which increases the burden of on-site operations. Summary of the Invention

[0004] To address the problems mentioned in the background art, the present invention aims to provide an exploration and sampling device for geothermal drilling and its usage method, which has the advantages of automatic fixing and cleaning, and solves the problem of unstable exploration on soft ground.

The inner wall of the guide cylinder is slidably connected to the surface of the connecting plate through a sliding groove. The surface of the connecting plate is fixedly connected to the lower end surface of the limiting rod.

[0007] In a preferred embodiment of the present invention, the auxiliary mechanism includes a fixed plate, a clamping claw, an assembly plate, a mating block, a mating threaded sleeve, a drive screw, a transmission rod, and a dual-head motor. The surface of the fixed plate is fixedly connected to the inner surface of the clamping claw, the surface of the clamping claw is fixedly connected to the surface of the assembly plate, the inner wall of the assembly plate is fixedly connected to the surface of the mating block, the inner wall of the mating block is rotatably connected to the outer end surface of the mating threaded sleeve, the inner wall of the mating threaded sleeve is threadedly connected to the surface of the drive screw, the inner wall of the drive screw is fixedly connected to the outer end surface of the transmission rod, and the inner end surfaces of the two transmission rods are respectively fixedly connected to the output ends on both sides of the dual-head motor.

[0008] In a preferred embodiment of the present invention, the pushing mechanism includes a hydraulic pump, a guide box, a hydraulic cylinder, a protective box, an electric push rod, and a stop plate. The surface of the hydraulic pump is fixedly connected to the outer surface of the guide box, the inner wall of the guide box is fixedly connected to the upper end of the hydraulic cylinder, the output end of the hydraulic cylinder is fixedly connected to the upper end of the protective box, the upper end of the guide box is rotatably connected to the lower end of the electric push rod via a rotating shaft, and the lower end of the guide box is fixedly connected to the surface of the stop plate.

[0009] In a preferred embodiment of the present invention, the upper surface of the dustproof cylinder is in contact with the lower surface of the fixing plate, the lower end of the spring is fixedly connected to the surface of the connecting plate, the upper end of the spring is fixedly connected to the inner wall of the guide cylinder, the surface of the limiting rod is slidably connected to the inner surface of the guide cylinder, and the inner walls at both ends of the fixing plate are respectively fixedly connected to the upper ends of the two limiting rods.

[0010] In a preferred embodiment of the present invention, the surface of the assembly plate is slidably connected to the inner wall of the protective box, the surface of the dual-head motor is fixedly connected to the inner wall of the protective box, the surface of the transmission rod is rotatably connected to the inner wall of the protective box through a bearing seat, the surface of the mating block is slidably connected to the inner wall of the protective box through a sliding groove, and the threads on the two active screw surfaces of the dual-head motor rotate in opposite directions.

[0011] In a preferred embodiment of the present invention, the inner wall of the guide box is slidably connected to the outer surface of the protective box via a sliding groove, and the surface of the stop plate is in contact with the lower surface of the protective box.

[0012] In a preferred embodiment of the present invention, the upper end of the electric push rod is rotatably connected to the rear surface of the mounting plate via a rotating shaft, and the lower end of the mounting plate is rotatably connected to the upper end of the guide box via a rotating shaft.

[0013] In a preferred embodiment of the present invention, in step S1, the entire device is first moved to the area to be explored and sampled. The dual-head motor inside the protective box is started, with its output ends connected to the drive screw via transmission rods. When the dual-head motor drives the transmission rods to rotate, the drive screw engages with the threaded sleeve on the inner wall of the mating block. Since the drive screws at both ends of the dual-head motor rotate in opposite directions, as they rotate, the threaded sleeve drives the mating block to move synchronously to both sides along the sliding groove provided on the inner wall of the protective box. When the mating block, along with the mounting plate it is fixed to, fully extends outside the protective box, the initial fixing operation of the device is completed.

[0014] S2. Subsequently, the hydraulic pump installed on the outside of the guide box is started to drive the hydraulic cylinder to extend. The output end of the hydraulic cylinder is fixedly connected to the upper end of the protective box. Therefore, when the hydraulic cylinder extends, it will push the protective box and its internal auxiliary mechanism to move smoothly down along the inner wall of the guide box until the limit rod on the positioning mechanism connected to the auxiliary mechanism contacts the ground soil.

[0015] S3. As the hydraulic cylinder pushes the protective box downwards, the surface of the assembly plate connects to the fixed plate via clamping claws, and the limiting rods on both sides of the fixed plate are inserted into the soil of the exploration area. The depth of the limiting rods inserted into the soil can be controlled by adjusting the extension of the hydraulic cylinder. When the limiting rods are inserted into the soil, the lower end of the dustproof cylinder's supporting plate contacts the ground surface, and the spring inside the dustproof cylinder accumulates elastic potential energy due to the stretching of the connecting plate connected to the limiting rod. After the exploration operation is completed, the hydraulic cylinder retracts, causing the limiting rods to rise. At this time, the spring releases its elastic potential energy, pushing the dustproof cylinder to slide along the surface of the limiting rods, thereby scraping off the soil adhering to the limiting rods. Once the limiting rods are firmly inserted into the soil and the overall device is stable, the exploration mechanism at the top of the guide box can be activated to carry out sampling operations.

[0016] S4. Finally, start the electric push rod to lift the mounting plate to the working position, then turn on the servo motor on the mounting plate to drive the guide rod to rotate, so that the drill bit at its lower end can start drilling operations to complete the exploration and sampling task.

[0017] 1. By setting up an exploration mechanism, this invention solves the problems of unstable fixation, low automation, and poor sampling efficiency of traditional soil exploration equipment in complex surface environments, and achieves the effects of rapid deployment, stable operation, and automatic cleaning and recycling.

[0018] 2. By setting up a positioning mechanism, the present invention uses a limiting rod in conjunction with a dustproof cylinder and a spring structure to solve the problem of soil adhesion and difficulty in recovery after the exploration rod is inserted, thereby achieving soil scraping and cleaning and improving the reliability of the equipment in wet or sticky soil.

[0019] 3. By setting up an auxiliary mechanism and using a dual-head motor to drive a reverse screw to synchronously push the assembly plate outward, this invention solves the problem of the device not being firmly fixed on soft ground at the beginning, realizes lateral expansion and pre-tightening support, and enhances overall stability.

[0022] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the present invention is described in detail with reference to the schematic diagrams.

Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth. Example

[0026] Reference Figures 1-6 In the first embodiment of the present invention, an exploration mechanism 1 is provided, including a drill bit 101, a guide rod 102, a servo motor 103, and a mounting plate 104. The upper end of the drill bit 101 is fixedly connected to the lower end of the guide rod 102, the upper end of the guide rod 102 is fixedly connected to the output end of the servo motor 103, the surface of the servo motor 103 is fixedly connected to the surface of the mounting plate 104, a positioning mechanism 2 is provided at the lower end of the mounting plate 104, an auxiliary mechanism 3 is provided on the positioning mechanism 2, and a pushing mechanism 4 is provided on the auxiliary mechanism 3. The positioning mechanism 2 is used to fix the entire exploration mechanism 1, the auxiliary mechanism 3 is used to assist the fixing process, and the pushing mechanism 4 is used to insert the positioning mechanism 2 into the soil.

[0027] Specifically, the exploration mechanism 1 drives the guide rod 102 via the servo motor 103 to rotate the drill bit 101 for drilling. In conjunction with the mounting plate 104 and the multi-stage auxiliary, positioning and pushing mechanism 4, it solves the problems of poor stability and low automation of traditional sampling equipment. The positioning mechanism 2 ensures reliable fixation of the device, the auxiliary mechanism 3 completes the lateral expansion support, and the pushing mechanism 4 controls the soil penetration depth, ensuring a smooth drilling process and improving the accuracy, efficiency and environmental adaptability of soil sampling.

[0028] Furthermore, the electric push rod 405 is activated to lift the mounting plate 104 to the working position, and then the servo motor 103 on the mounting plate 104 is turned on to drive the guide rod 102 to rotate, so that the lower drill bit 101 can drill in and complete the exploration and sampling task. Example

[0029] In a second embodiment of the present invention, a positioning mechanism 2 is provided, comprising a support plate 201, a dustproof cylinder 202, a spring 203, a guide cylinder 204, a connecting plate 205, and a limiting rod 206. The upper end of the support plate 201 is fixedly connected to the lower end of the dustproof cylinder 202. The spring 203 is disposed inside the dustproof cylinder 202. The inner wall of the dustproof cylinder 202 is fixedly connected to the surface of the guide cylinder 204. The inner wall of the guide cylinder 204 is slidably connected to the surface of the connecting plate 205 through a sliding groove. The surface of the connecting plate 205 is fixedly connected to the lower end surface of the limiting rod 206. The upper surface of the dustproof cylinder 202 is in contact with the lower surface of the fixing plate 301. The lower end of the spring 203 is fixedly connected to the surface of the connecting plate 205. The upper end of the spring 203 is fixedly connected to the inner wall of the guide cylinder 204. The surface of the limiting rod 206 is slidably connected to the inner surface of the guide cylinder 204. The inner walls at both ends of the fixing plate 301 are respectively fixedly connected to the upper ends of the two limiting rods 206.

[0030] Specifically, the positioning mechanism 2, through the synergy of the limiting rod 206, the dustproof cylinder 202, and the spring 203, effectively solves the problems of unstable positioning of exploration equipment in soft soil and soil adhesion during retrieval. After the limiting rod 206 is inserted into the soil, the bearing plate 201 contacts the ground surface, improving support stability. The spring 203 stores energy under the tension of the connecting plate 205 and releases the energy after the operation, pushing the dustproof cylinder 202 to slide along the limiting rod 206, thereby scraping off the soil on the surface of the rod and improving work efficiency. The guide cylinder 204 and the chute structure ensure the smooth movement of the connecting plate 205 and prevent jamming.

[0031] Furthermore, the device is moved to the area to be explored and sampled, and the dual-head motor 308 inside the protective box 404 is started. Its output ends on both sides are connected to the active screw 306 via the transmission rod 307. When the motor drives the transmission rod 307 to rotate, the active screw 306 engages with the mating sleeve 305 inside the mating block 304. Since the two active screws 306 rotate in opposite directions, when they rotate, the mating sleeve 305 drives the mating block 304 to move synchronously to both sides along the sliding groove on the inner wall of the protective box 404. The mating block 304 drives the assembly plate 303 to extend completely outside the protective box 404, thus completing the initial fixation of the device. Example

[0032] The third embodiment of the present invention provides an auxiliary mechanism 3 including a fixed plate 301, a clamping claw 302, an assembly plate 303, a mating block 304, a mating threaded sleeve 305, a drive screw 306, a transmission rod 307, and a dual-head motor 308. The surface of the fixed plate 301 is fixedly connected to the inner surface of the clamping claw 302, the surface of the clamping claw 302 is fixedly connected to the surface of the assembly plate 303, the inner wall of the assembly plate 303 is fixedly connected to the surface of the mating block 304, the inner wall of the mating block 304 is rotatably connected to the outer end surface of the mating threaded sleeve 305, and the inner wall of the mating threaded sleeve 305 is rotatably connected to the drive screw 306. 6. Surface threaded connection: The inner wall of the active screw 306 is fixedly connected to the outer end surface of the transmission rod 307. The inner end surfaces of the two transmission rods 307 are respectively fixedly connected to the output ends on both sides of the dual-head motor 308. The surface of the assembly plate 303 is slidably connected to the inner wall of the protective box 404. The surface of the dual-head motor 308 is fixedly connected to the inner wall of the protective box 404. The surface of the transmission rod 307 is rotatably connected to the inner wall of the protective box 404 through a bearing seat. The surface of the mating block 304 is slidably connected to the inner wall of the protective box 404 through a sliding groove. The threads on the surfaces of the active screws 306 on both sides of the dual-head motor 308 rotate in opposite directions.

[0033] Specifically, the auxiliary mechanism 3 drives the active screw 306 with reverse threads to rotate synchronously through the dual-head motor 308, which drives the mating block 304 and the assembly plate 303 to expand symmetrically outward along the slide groove. This solves the problem of weak adhesion and easy displacement of traditional fixing methods on soft or uneven ground, and realizes the rapid deployment and lateral stable support of the device. The transmission structure of the mating screw sleeve 305 and the screw has self-locking characteristics, ensuring that the structure is stable and reliable after deployment. The assembly plate 303 is linked to the fixing plate 301 through the clamping claw 302, providing a force base for subsequent hydraulic pressing. The whole system realizes automated deployment and pre-fixation, improving the deployment efficiency and operational safety of the equipment in complex terrain.

[0034] Furthermore, the hydraulic pump 401 on the outside of the guide box 402 is activated, driving the hydraulic cylinder 403 to extend. Since the output end of the hydraulic cylinder 403 is fixed to the upper end of the protective box 404, when it extends, it will push the protective box 404 and the internal auxiliary mechanism 3 to move smoothly down along the inner wall of the guide box 402 until the limit rod 206 on the positioning mechanism 2 contacts the ground soil. Example

[0035] In the fourth embodiment of the present invention, a pushing mechanism 4 is provided, comprising a hydraulic pump 401, a guide box 402, a hydraulic cylinder 403, a protective box 404, an electric push rod 405, and a travel plate 406. The surface of the hydraulic pump 401 is fixedly connected to the outer surface of the guide box 402. The inner wall of the guide box 402 is fixedly connected to the upper end of the hydraulic cylinder 403. The output end of the hydraulic cylinder 403 is fixedly connected to the upper end of the protective box 404. The upper end of the guide box 402 is rotatably connected to the lower end of the electric push rod 405 via a rotating shaft. The lower end of the guide box 402 is fixedly connected to the surface of the travel plate 406. The inner wall of the guide box 402 is slidably connected to the outer surface of the protective box 404 via a sliding groove. The surface of the travel plate 406 contacts the lower surface of the protective box 404. The upper end of the electric push rod 405 is rotatably connected to the rear surface of the mounting plate 104 via a rotating shaft. The lower end of the mounting plate 104 is rotatably connected to the upper end of the guide box 402 via a rotating shaft.

[0036] Specifically, the pushing mechanism 4, through the cooperation of the hydraulic cylinder 403 and the sliding connection structure, realizes the stable pressing and positioning of the exploration equipment, effectively solving the problem of easy tilting and unstable fixation of the device under soft geological conditions. The electric push rod 405 is connected to the multi-point rotating shaft, ensuring the reliability of the unfolding of the mounting plate 104 and the adaptability of the working space. The dustproof cylinder 202 and the spring 203 are self-cleaning, which improves the recovery efficiency of the limit rod 206 while avoiding the interference of soil residue on subsequent operations, and enhances the continuous operation capability of the equipment in complex environments.

[0037] Furthermore, when the hydraulic cylinder 403 pushes the protective box 404 downward, the surface of the assembly plate 303 is connected to the fixed plate 301 via the clamping claw 302. The limiting rods 206 on both sides of the fixed plate 301 are inserted into the soil of the exploration area. The extension of the hydraulic cylinder 403 can control the depth of the limiting rods 206 in the soil. When the limiting rods 206 are in the soil, the bearing plate 201 at the lower end of the dustproof cylinder 202 contacts the ground surface. The spring 203 inside the dustproof cylinder 202 stores energy due to the stretching of the connecting plate 205. After the exploration is completed, the hydraulic cylinder 403 retracts, causing the limiting rods 206 to rise. The spring 203 releases energy and pushes the dustproof cylinder 202 to slide along the rod, scraping off the soil on the rod. After the limiting rods 206 are firmly inserted into the soil and the device is stable, the exploration mechanism 1 at the upper end of the guide box 402 is started to carry out sampling operations.

[0038] First, the entire exploration device is moved to the target exploration area, ensuring the equipment is in a stable and unobstructed working environment. Then, the dual-head motor 308 inside the protective box 404 is started. Its output ends are connected to two drive screws 306 via transmission rods 307. When the motor runs, it drives the transmission rods 307 and drive screws 306 to rotate synchronously. Because the drive screws 306 at both ends of the dual-head motor 308 have reverse threads and form a threaded engagement with the mating sleeves 305 installed on the inner wall of the mating block 304, when the screws rotate, the mating block 304 is activated by the threaded transmission. The device moves symmetrically to both sides using the sliding grooves provided on the inner wall of the lower edge protective box 404. The mating block 304 is fixedly connected to the assembly plate 303. Therefore, as the mating block 304 moves outward, the assembly plate 303 gradually extends outward from the protective box 404 until it is fully unfolded. This process realizes the lateral expansion and initial support and fixation of the device in the working area, providing a structural foundation for subsequent stable operation. After the initial fixation is completed, the hydraulic pump 401 installed on the outside of the guide box 402 is started, driving the piston rod of the hydraulic cylinder 403 to extend. The output end of the hydraulic cylinder 403 is connected to the upper end of the protective box 404. Therefore, as the hydraulic cylinder 403 extends, the protective box 404 and its internal auxiliary mechanism 3 move vertically downward along the inner wall of the guide box 402. During this process, the clamping claws 302 on the outer side of the assembly plate 303 remain connected to the fixing plate 301, and the limiting rods 206 on both sides of the fixing plate 301 move downward and insert into the soil of the exploration area. By controlling the oil supply of the hydraulic pump 401 and adjusting the extension stroke of the hydraulic cylinder 403, the insertion depth of the limiting rods 206 into the soil can be controlled to adapt to the stability requirements under different geological conditions. When drill bit 206 is inserted into the soil, the bearing plate 201 at the lower end of the dustproof cylinder 202, which is fitted on its outside, contacts the ground surface, providing support and limiting function. At the same time, the spring 203 inside the dustproof cylinder 202 is stretched due to the relative upward movement of the connecting plate 205 on the limiting rod 206, accumulating elastic potential energy to provide power reserve for the subsequent automatic cleaning function. When the limiting rod 206 reaches the predetermined depth and the entire device remains stable, the vertical positioning and fixing are completed, providing a reliable support platform for exploration operations. After the device completes lateral expansion and vertical fixing, the exploration and sampling stage begins. First, the electric push rod 405 is activated, pushing out the piston rod and gradually raising the mounting plate 104 from the retracted state to the predetermined working angle, ensuring that the drill bit has sufficient working space and structural stability. Then, the servo motor 103 on the mounting plate 104 is turned on, and the power is transmitted to the guide rod 102 through the transmission structure, driving it to rotate the lower drill bit 101 at high speed, starting the drilling and sampling operation on the soil. Throughout the sampling process, the device structure remains stable, and all components operate in coordination to ensure sampling continuity and sample integrity. After the sampling task is completed, the hydraulic cylinder 403 will retract, causing the protective box 404 and the limit rod 206 to lift upwards as a whole.At this time, the soil attached to the surface of the limit rod 206 will be removed during the sliding of the dust cover 202. The spring 203 releases the elastic potential energy accumulated in the early stage, pushing the dust cover 202 to reset downward along the limit rod 206, realizing the automatic soil scraping function, effectively preventing residual soil from interfering with subsequent operations, and preparing for equipment transfer or the next operation.

[0039] In summary, through the coordinated operation of the propulsion mechanism, auxiliary mechanism, positioning mechanism, and exploration mechanism, the device achieves automatic deployment, stable fixation, controllable depth insertion, drilling and sampling, and cleaning of the limit rod in soft or uneven ground environments. The synchronous expansion of the auxiliary mechanism provides a lateral support foundation for the device, the propulsion mechanism drives the protective box downward to insert the limit rod into the soil, the positioning mechanism enhances stability under the support of the bearing plate and uses spring potential energy to achieve cleaning during recovery, and the exploration mechanism completes the sampling task after the structure is stabilized.

9. An exploration and sampling device for geothermal drilling and its method of use, comprising the exploration and sampling device for geothermal drilling as described in any one of claims 1 to 8, characterized in that: include, S1. First, move the entire device to the area to be explored and sampled, and start the double-headed motor (308) in the protective box (404). Its output ends on both sides are connected to the active screw (306) through the transmission rod (307). When the double-headed motor (308) drives the transmission rod (307) to rotate, the active screw (306) engages with the threaded sleeve (305) on the inner wall of the mating block (304). Since the active screws (306) at both ends of the double-headed motor (308) rotate in opposite directions, as it rotates, the mating sleeve (305) will drive the mating block (304) to move synchronously to both sides along the sliding groove provided on the inner wall of the protective box (404). When the mating block (304) drives the mounting plate (303) fixed to it to fully extend out of the protective box (404), the initial fixing operation of the device is completed. S2. Then, start the hydraulic pump (401) installed on the outside of the guide box (402) to drive the hydraulic cylinder (403) to extend. The output end of the hydraulic cylinder (403) is fixedly connected to the upper end of the protective box (404). Therefore, when the hydraulic cylinder (403) extends, it will push the protective box (404) and its internal auxiliary mechanism (3) to move smoothly down along the inner wall of the guide box (402) until the limit rod (206) on the positioning mechanism (2) connected to the auxiliary mechanism (3) contacts the ground soil. S3. During the process of the hydraulic cylinder (403) pushing the protective box (404) downward, the surface of the assembly plate (303) is connected to the fixed plate (301) through the clamping claws (302). The limiting rods (206) on both sides of the fixed plate (301) are inserted into the soil of the exploration area. By adjusting the extension of the hydraulic cylinder (403), the depth of the limiting rods (206) inserted into the soil can be controlled. When the limiting rods (206) are inserted into the soil, the lower end bearing plate (201) of the dustproof cylinder (202) outside it contacts the ground surface. At the same time, the spring inside the dustproof cylinder (202) (203) Because the connecting plate (205) connected to the limit rod (206) is stretched and accumulates elastic potential energy, after the exploration operation is completed, the hydraulic cylinder (403) retracts and drives the limit rod (206) to rise. At this time, the spring (203) releases elastic potential energy and pushes the dustproof cylinder (202) to slide along the surface of the limit rod (206), thereby scraping off the soil attached to the limit rod (206). After the limit rod (206) is firmly inserted into the soil and the device is stable as a whole, the exploration mechanism (1) at the top of the guide box (402) can be started to carry out sampling operation. S4. Finally, start the electric push rod (405) to lift the mounting plate (104) to the working position, then turn on the servo motor (103) on the mounting plate (104) to drive the guide rod (102) to rotate, so that the drill bit (101) at its lower end can start drilling operations to complete the exploration and sampling task.
