Technical Field

[0001] This invention relates to the field of geological sampling technology, and in particular to a geological engineering exploration sampling device. Background Technology

[0002] Geological engineering exploration sampling equipment is a complete set of tools and instruments used to obtain physical samples such as surface and underground soil, rock, and water samples. Its core function is to provide direct physical basis and data support for accurately analyzing the physical and mechanical properties of soil and rock masses, determining the stratigraphic structure, assessing the bearing capacity of the foundation, and judging the risk of geological disasters by collecting representative geological samples and conducting on-site tests. This ensures the safety, reliability, and economic rationality of engineering site selection, design, and construction, and is an indispensable technical means to connect geological conditions with engineering practice.

[0003] When existing surveying and sampling equipment operates in rugged terrain such as mountains, riverbanks, and hills, vehicle tilting causes two major problems: first, the drill bit cannot drill vertically, affecting sampling quality and data accuracy; second, the overall stability of the vehicle is poor, posing a safety hazard. Common solutions include manually placing sleepers or using simple mechanical outriggers, which are inefficient and have poor leveling accuracy.

[0004] Therefore, a geological engineering exploration sampling device is proposed to address the above problems. Summary of the Invention

[0006] The technical solution adopted by the present invention to solve its technical problem is: a geological engineering exploration and sampling device, including a base, a drilling tool installed on the top of the base, and an adjustment structure installed on the bottom of the base. The adjustment structure includes a hydraulic component, a support adjustment component, a flow control component, an overload protection component, an energy storage buffer component, an auxiliary component, and a system control mechanism. The hydraulic component includes a diverter valve for adjusting the supply of hydraulic oil. The support adjustment component includes an upper support leg, a piston block assembly slidably connected inside the upper support leg, and a lower support leg provided at the bottom of the piston block assembly. The upper support leg, the piston block assembly, and the lower support leg constitute a hydraulic cylinder mechanism for adjusting the height of the base.

[0007] Preferably, the hydraulic assembly includes a hydraulic oil tank, a hydraulic pump, and a flow divider valve fixedly installed on the top of the base. The input end of the hydraulic pump extends to the bottom of the hydraulic oil tank, and the output end of the hydraulic pump is fixedly connected to the input end of the flow divider valve. The output end of the flow divider valve is provided with four oil distribution pipes, and the bottom end of each oil distribution pipe is connected to the upper support leg.

[0008] Preferably, the support adjustment assembly further includes a support seat slidably connected to the outside of the lower support leg, the bottom of the support seat being inverted conical.

[0009] Preferably, a plurality of dampers are arranged in a ring around the bottom of the inner side of the support base and the opposite side of the bottom of the lower support leg.

[0010] Preferably, the support adjustment assembly further includes a universal ball fixedly installed on the top of the upper support leg, and a mounting seat is fixedly installed at the bottom end of the base, the mounting seat being rotatably connected to the outer wall of the universal ball.

[0011] Preferably, the auxiliary component includes a spherical slider fixedly connected to the outside of the support base, and a butterfly-shaped support plate is rotatably connected to the outer wall of the spherical slider. The bottom end of the butterfly-shaped support plate is set to be uneven.

[0012] Preferably, the flow control component includes a three-way shut-off valve installed at the bottom of the oil distribution pipe. The output end of the three-way shut-off valve is provided with a main passage pipe and a secondary passage pipe connected to the upper support leg. A pressure sensor is installed between the bottom of the support base and the opposite surface of the lower support leg. Both the three-way shut-off valve and the pressure sensor are electrically connected to the system control mechanism.

[0013] Preferably, the overload protection component includes a mounting bracket fixedly connected to the bottom of the base. Four sets of pressure relief pipes are fixedly connected to the middle of the mounting bracket. Corrugated pipes are fixedly connected to both ends of the four sets of pressure relief pipes. The four sets of pressure relief pipes and corrugated pipes connect the upper support legs of the four sets of support adjustment components. A solenoid valve is installed near the outer wall of an upper support leg of each pressure relief pipe. The piston block assembly is divided into an upper piston block and a lower piston block. Several elastic telescopic rods and signal contacts are provided between the opposite surfaces of the upper piston block and the lower piston block.

[0014] Preferably, the energy storage and buffer assembly includes a rectangular box, which is connected to the top of the upper support leg through a thin round tube. Airbags are provided at both the upper and lower positions inside the rectangular box, and piston plates are fixedly connected to the opposite surfaces of the two airbags.

[0015] Preferably, the system control mechanism includes a signal acquisition unit, a central processing unit, a valve control unit, and a process control unit; The signal acquisition unit is used to synchronously receive the load signals of each pressure sensor and the trigger signals of each signal contact, and transmit the two types of signals to the central processing unit. The central processing unit performs comprehensive analysis and processing of load signals and trigger signals to determine the load size, overload status, overload degree and equipment leveling status of each support adjustment component, and generates flow control commands, path control commands and overload pressure relief commands.

[0017] This invention provides a geological engineering exploration and sampling device. Through the scientific design and collaborative operation of its core components, it demonstrates significant advantages. The three states of the three-way on / off valve accurately match different operation stages. The differentiated design of the main and auxiliary passages ensures both the accuracy of synchronous ground contact and meets the flow requirements for rapid replenishment. Combined with the flow divider valve to dynamically distribute the flow, it ensures that the leveling process is efficient and smooth, providing key technical support for the stable operation of the equipment.

[0018] This invention provides a geological engineering exploration sampling device. The device's buffer and stabilizing structure significantly improves sampling accuracy. The damper and energy storage buffer components can effectively absorb impact loads and pressure fluctuations. The butterfly support plate enhances ground adhesion, and the omnidirectional ball ensures that the support legs always remain vertical, reducing the impact of vibration on sampling operations, ensuring vertical drilling, and improving the integrity of geological samples and the accuracy of test data.

[0019] This invention provides a geological engineering exploration and sampling device. Through fully automated control, it reduces the difficulty of operation and energy consumption.

[0022] 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.

[0023] Specific implementation examples are given below.

[0024] Please see Figure 1 - Figure 7The present invention provides a technical solution: a geological engineering exploration and sampling device, including a base 1, a drilling tool 2 installed on the top of the base 1, and an adjustment structure 3 installed on the bottom of the base 1. The adjustment structure 3 includes a hydraulic component 31, a support adjustment component 32, a flow control component 33, an overload protection component 34, an energy storage buffer component 35, an auxiliary component 36, and a system control mechanism 37. The hydraulic component 31 includes a diverter valve 313 for adjusting the supply of hydraulic oil. The support adjustment component 32 includes an upper support leg 321, a piston block assembly 323 slidably connected inside the upper support leg 321, and a lower support leg 324 provided at the bottom of the piston block assembly 323. The upper support leg 321, the piston block assembly 323, and the lower support leg 324 constitute a hydraulic cylinder mechanism for adjusting the height of the base 1.

[0025] The drilling tool 2 installed on the top of the base 1 can meet the core operational requirements of geological exploration and sampling. The adjustment structure 3 at the bottom of the base 1 integrates hydraulic components 31, support adjustment components 32, flow control components 33, overload protection components 34, energy storage buffer components 35, auxiliary components 36 and system control mechanism 37. Through the hydraulic cylinder mechanism composed of upper support leg 321, piston block assembly 323 and lower support leg 324, the height of the four corners of the base 1 can be flexibly adjusted to effectively adapt to the leveling requirements of different terrains and provide a stable foundation for sampling operations. At the same time, the coordinated work of each component can take into account the support stability, overload protection and buffer performance, and improve the overall operational reliability of the equipment.

[0026] like Figure 1 As shown, the hydraulic assembly 31 includes a hydraulic oil tank 311, a hydraulic pump 312, and a flow divider valve 313, all fixedly mounted on the top of the base 1. The input end of the hydraulic pump 312 extends to the bottom of the hydraulic oil tank 311. The output end of the hydraulic pump 312 is fixedly connected to the input end of the flow divider valve 313. The output end of the flow divider valve 313 is provided with four oil distribution pipes, the bottom ends of which are connected to the upper support leg 321.

[0027] The flow divider valve 313 can dynamically switch the flow distribution ratio according to the load difference of each support adjustment component 32. The four oil distribution pipes accurately deliver the diverted hydraulic oil to the corresponding upper support leg 321, ensuring that the overload side gets more flow quota and the non-overload side maintains the appropriate flow, providing precise power support for rapid extension and synchronous follow-up, and improving the dynamic adaptability and oil supply efficiency of the hydraulic system.

[0028] As shown in Figure 5, the support adjustment assembly 32 also includes a support base 325 that is slidably connected to the outside of the lower support leg 324. The bottom of the support base 325 is inverted conical, and several dampers 326 are arranged around the bottom of the support base 325 and the opposite surface of the bottom of the lower support leg 324.

[0029] In the support adjustment assembly 32, the support base 325 is slidably connected to the outside of the lower support leg 324. Its bottom inverted cone design can enhance the embeddability with the ground and improve the support stability. The damper 326 between the bottom of the support base 325 and the bottom of the lower support leg 324 can effectively buffer the impact load during the support process, reduce the impact of vibration on the equipment and sampling operation, and avoid support offset or sampling accuracy loss due to impact.

[0030] like Figure 4 As shown, the support adjustment assembly 32 also includes a universal ball 322 fixedly installed on the top of the upper support leg 321, and a mounting seat is fixedly installed at the bottom of the base 1, with the mounting seat rotatably connected to the outer wall of the universal ball 322.

[0031] The universal ball 322 fixedly installed on the top of the support leg 321 is rotatably connected to the mounting seat at the bottom of the base 1, which can keep the upper support leg 321 in a vertical state when adjusting with the ground slope, ensuring that the extension and retraction of the hydraulic cylinder mechanism is precise and efficient, avoiding poor hydraulic oil supply or component wear caused by tilting, and improving the leveling reliability of the equipment on uneven ground and the service life of the components.

[0032] like Figure 4 As shown, the auxiliary component 36 includes a spherical slider 361 fixedly connected to the outside of the support base 325. A butterfly support plate 362 is rotatably connected to the outer wall of the spherical slider 361. The bottom end of the butterfly support plate 362 is set to be uneven.

[0033] The ball-shaped slider 361, which is fixedly connected to the support base 325, can drive the butterfly support plate 362 to rotate flexibly. The butterfly support plate 362 can increase the contact area with the ground, and its uneven bottom design can enhance the friction with the ground, effectively preventing the equipment from slipping or sinking on soft or sloping ground. The rotation of the ball-shaped slider 361, combined with the structural advantages of the butterfly support plate 362, allows the equipment to better adapt to complex terrains such as mountains and riverbanks, and improves the stability of the support.

[0034] like Figure 4 and Figure 5 As shown, the flow control component 33 includes a three-way shut-off valve 331 installed at the bottom of the oil distribution pipe. The output end of the three-way shut-off valve 331 is provided with a main passage pipe 332 and a secondary passage pipe 333 connected to the upper support leg 321. A pressure sensor 334 is installed between the bottom of the support base 325 and the opposite surface of the lower support leg 324. Both the three-way shut-off valve 331 and the pressure sensor 334 are electrically connected to the system control mechanism 37.

[0035] The three-way shut-off valve 331 at the bottom of the oil distribution pipe is the core component for realizing graded oil supply. It can accurately switch between three states: only the secondary passage pipe 333 is open, both the main passage pipe 332 and the secondary passage pipe 333 are open, and both passages are completely closed. The difference in flow area between the main passage pipe 332 and the secondary passage pipe 333 can respectively meet the small flow requirements of synchronous grounding, the large flow requirements of rapid replenishment, and the closed pressure holding requirements after leveling. The pressure sensor 334 between the support base 325 and the lower support leg 324 provides real-time feedback of the load signal, which, together with the system control mechanism 37, enables precise switching of the passage state. This is a key guarantee for improving leveling efficiency, accuracy, and stability.

[0036] like Figure 2 , Figure 3 and Figure 6 As shown, the overload protection component 34 includes a mounting bracket 341 fixedly connected to the bottom of the base 1. Four sets of pressure relief pipes 342 are fixedly connected to the middle of the mounting bracket 341. Corrugated pipes 343 are fixedly connected to both ends of the four sets of pressure relief pipes 342. The four sets of pressure relief pipes 342 and the corrugated pipes 343 connect the upper support legs 321 of the four sets of support adjustment components 32. A solenoid valve 346 is installed near the outer wall of an upper support leg 321 of each pressure relief pipe 342. The piston block assembly 323 is divided into an upper piston block and a lower piston block. Several elastic telescopic rods 344 and signal contacts 345 are provided between the opposite surfaces of the upper piston block and the lower piston block.

[0037] Mounting bracket 341 provides a stable mounting base for pressure relief pipe 342. The four sets of pressure relief pipes 342 are connected to the upper support legs 321 of the four sets of support adjustment components 32 through bellows 343. Bellows 343 can adapt to the tilt angle deviation of the upper support legs 321 to ensure the sealing of the pipeline connection and structural adaptability. The solenoid valve 346 on the pressure relief pipe 342 can accurately control the opening and closing of the pressure relief action. When the base 1 is tilted, the lower support leg 324 on the lower side bears more load. If the tilt angle is too large, the lower support leg 324 on the lower side will bear overload pressure. When the upper and lower piston blocks of the piston block assembly 323 approach each other, the signal contact 345 can trigger the overload signal in time. With the help of the system control mechanism 37, the overload pressure is distributed to the adjacent support adjustment components 32, avoiding the single component from bearing excessive load and effectively protecting the hydraulic cylinder mechanism and pipeline.

[0038] like Figure 7 As shown, the energy storage buffer assembly 35 includes a rectangular box 351. The rectangular box 351 is connected to the top of the upper support leg 321 through a thin round tube. Airbags 352 are provided at both the upper and lower positions inside the rectangular box 351. Piston plates 353 are fixedly connected to the opposite surfaces of the two airbags 352.

[0039] The rectangular box 351 is connected to the top of the upper support leg 321 through a thin round tube, so that the hydraulic pressure change in the upper support leg 321 can be transmitted to the inside of the rectangular box 351. The two airbags 352 and the piston plate 353 work together to effectively absorb the pressure fluctuation of the hydraulic system and play an energy storage and buffering role. After leveling, it can maintain the oil circuit pressure state, reduce the energy consumption of continuous oil supply by the hydraulic pump 312, and at the same time buffer the impact of sampling operation and ground vibration, ensuring the long-term stable operation of the equipment.

[0040] like Figures 1-7 As shown, the system control mechanism 37 includes a signal acquisition unit 371, a central processing unit 372, a valve control unit 373, and a process control unit 374; The signal acquisition unit 371 is used to synchronously receive the load signals of each pressure sensor 334 and the trigger signals of each signal contact 345, and transmit the two types of signals to the central processing unit 372. The central processing unit 372 performs comprehensive analysis and processing of load signals and trigger signals, determines the load size, overload status, overload degree and equipment leveling status of each support adjustment component 32, and generates flow control commands, path control commands and overload pressure relief commands. The valve control unit 373 controls the flow distribution ratio of the diverter valve 313 to switch according to the flow control command, controls the three-way on / off valve 331 to switch to the state of only the secondary passage being open, both passages being open, or both passages being completely closed according to the passage control command, and controls the solenoid valve 346 on the pressure relief pipe 342 to open or close according to the overload pressure relief command. The process control unit 374 controls the entire leveling and overload protection process according to preset logic.

[0041] The signal acquisition unit 371 of the system control mechanism 37 can synchronously receive and accurately transmit the load signals of each pressure sensor 334 and the trigger signals of each signal contact 345. The central processing unit 372 performs comprehensive analysis and processing of the signals to accurately determine the load status, overload degree and equipment leveling status of the support adjustment component 32. The valve control unit 373 accurately controls the flow distribution ratio of the diversion valve 313, the passage status of the three-way on / off valve 331 and the on / off of the solenoid valve 346 on the pressure relief pipe 342 according to the instructions. The process control unit 374 coordinates the entire leveling and overload protection process according to the preset logic to achieve fully automated and precise control without manual intervention, improve leveling efficiency and operational safety, and ensure the accuracy and stability of sampling operations.

[0042] The working principle of this invention is as follows: In use, the base 1 is first pushed to the corresponding sampling position. The process control unit 374 of the system control mechanism 37 first starts the hydraulic pump 312. The hydraulic pump 312 draws hydraulic oil from the hydraulic oil tank 311 and delivers it to the flow divider valve 313. At this time, the flow divider valve 313 evenly distributes the flow rate in a 1:1:1:1 ratio, precisely delivering it through four oil distribution pipes to the three-way valves 331 at the bottom of each oil distribution pipe. Initially, the three-way valves 331 are in a state where only the secondary passage pipe 333 is open. The small flow area of ​​the secondary passage pipe 333 enables precise distribution of small flow rates, which is crucial to ensuring that the four support adjustment components 32 extend and touch the ground synchronously, avoiding initial tilting due to uneven flow. The hydraulic oil enters the cylinder chamber of the upper support leg 321 through the secondary passage pipe 333, pushing the piston block assembly 323 to move the lower support leg 324 downwards. The universal ball 322 at the top of the upper support leg 321 and the bottom of the base 1... The rotating mounting base ensures that the upper support leg 321 remains vertical, preventing hydraulic oil supply disruptions or component wear due to tilting. When the lower support leg 324 moves downward, it drives the support base 325 to move synchronously. The spherical slider 361 on the outside of the support base 325 drives the butterfly support plate 362 to rotate flexibly. The butterfly support plate 362 increases the contact area with the ground, and its uneven bottom design enhances friction, effectively preventing the equipment from slipping and sinking on soft or sloping ground. The inverted cone design at the bottom of the support base 325 further improves its embeddability with the ground. In conjunction with the damper 326 arranged in a ring between the support base 325 and the lower support leg 324, it can effectively buffer the impact load during the support process and reduce vibration. The pressure sensor 334 between the support base 325 and the lower support leg 324 detects the load signal in real time and transmits it to the central processing unit 372 through the signal acquisition unit 371 of the system control mechanism 37. When the pressure sensor 334 detects that all support adjustment components 32 are in contact with the ground and there is a load difference, the central processing unit 372 quickly determines the overload side support adjustment component 32 and then generates flow control command and passage control command. The valve control unit 373 controls the three-way on / off valve 331 on the overload side to switch to the dual-pass conduction state of the main passage pipe 332 and the auxiliary passage pipe 333 according to the command. The flow area of ​​the main passage pipe 332 is larger than that of the auxiliary passage pipe 333. The dual-pass conduction can provide a large flow to meet the needs of rapid expansion on the overload side. This is also the core necessity of the main and auxiliary passage design, which ensures both the accuracy of synchronous ground contact and the efficiency of rapid expansion. At the same time, the valve control unit 373 controls the diversion valve 313 to increase the flow quota on the overload side and reduce the flow quota on the non-overload side, so that the overload side support adjustment component 32 can quickly expand, and the non-overload side maintains the appropriate flow to keep up synchronously, ensuring that the base 1 quickly tends to be horizontal. If the overload side load is too large, the upper and lower piston blocks of the piston block assembly 323 will approach each other and compress the elastic telescopic rod 344. When the signal contact 345 contacts and triggers the overload signal, the central processing unit 372 will generate an overload pressure relief command first. The valve control unit 373 controls the solenoid valve 346 on the corresponding pressure relief pipe 342 to open. The four pressure relief pipes 342 connect the upper support legs 321 of the four support adjustment components 32 through the bellows 343. The bellows 343 can adapt to the tilt angle deviation of the upper support legs 321, ensuring the sealing of the pipeline connection and the structural adaptability. The overload pressure is distributed to the adjacent support adjustment components 32 through the pressure relief pipes 342, avoiding a single component from bearing an excessive load, effectively protecting the hydraulic cylinder mechanism and pipeline. After the overload is released, the solenoid valve 346 closes and the equipment resumes the extension process. When the load values ​​of the four pressure sensors 334 are the same and tend to be stable, the central processing unit 372 determines that the equipment has completed the leveling. The valve control unit 373 controls the three-way on / off valve 331 to switch to a state where the main passage pipe 332 and the auxiliary passage pipe 333 are completely closed. This state can lock the oil circuit to prevent hydraulic oil backflow and at the same time shut down the hydraulic pump 312. The rectangular box 351 of the energy storage buffer component 35 is connected to the top of the upper support leg 321 through a thin round pipe. The two air bladders 352 inside cooperate with the piston plate 353 to effectively absorb the pressure fluctuations of the hydraulic system and play an energy storage and buffering role. This not only maintains the oil circuit pressure state and reduces the energy consumption of the hydraulic pump 312 for continuous oil supply, but also buffers the impact of sampling operations and ground vibration. At this time, the base 1 remains stable and horizontal. The drill bit 2 is started to carry out geological exploration and sampling. During the sampling process, the damper 326 works with the energy storage buffer component 35 to continuously absorb vibration. The butterfly support plate 362 provides stable support. The system control mechanism 37 monitors the signals of the pressure sensor 334 and the signal contact 345 in real time. If pressure fluctuations or overloads occur, adjustments can be made in time. After the sampling is completed, the system control mechanism 37 controls the three-way shut-off valve 331 to switch to the dual-path conduction state. The hydraulic pump 312 works in reverse or recovers hydraulic oil through a dedicated pressure relief pipeline. Each support adjustment component 32 retracts and resets, completing the entire geological exploration and sampling operation process.
