Description

Technical Field

[0001] The invention relates to the technical field of mineral exploration, and in particular to a sampling device used for copper mine exploration. Background Art

[0002] As an important metal mineral, copper is widely used in electronics, construction, transportation and other fields. With the advancement of science and technology and the development of industry, the demand for copper resources is increasing, and it is particularly important to improve the efficiency and accuracy of copper mineral exploration. As a key tool for mineral exploration, the performance and technical level of sampling equipment directly affect the reliability and economy of exploration results.

[0003] In the traditional copper mine exploration process, sampling equipment usually relies on manual operation or semi-mechanized technology. These devices mainly include key components such as base, drilling motor and drill bit. The base serves as the supporting structure of the equipment to ensure the stability of the entire system; the drilling motor is responsible for providing power to drive the drill bit to rotate and realize the feeding action; and the drill bit is in direct contact with the ore to complete the sampling work. Although this vertical rotation sampling method is simple, its positioning mainly depends on surface detection, and then a single vertical drilling is used to obtain the sample. This method has a certain degree of randomness, and inaccurate positioning will lead to multiple drilling problems. Therefore, the accuracy and efficiency of sampling are often unsatisfactory.

[0004] In order to improve the accuracy and efficiency of sampling and reduce the situation of ineffective drilling, we need to design a sampling device for copper mine exploration. This device should be able to reduce the blindness of drilling through more accurate positioning technology, thereby improving the pertinence and efficiency of sampling. Summary of the invention

[0005] In order to solve the above problems, the present invention provides a sampling device for copper mine mineral exploration, which adds lateral sampling while vertical drilling sampling, realizes energy-saving and intelligent lateral sampling through a control system, and improves the sampling efficiency of copper mine mineral exploration.

[0006] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: a sampling device for copper ore exploration, comprising a base, a driving box body is fixedly connected to the base, a drilling motor is fixedly connected to the driving box body, a drill rod is coaxially fixedly connected to the output shaft of the drilling motor, a rod hole is provided at the bottom of the driving box body, a drill bit is fixedly connected to the bottom end of the drill rod, a plurality of sampling grooves are provided along the circumference of the drill rod side wall, a monitoring component for detecting the presence of copper ore is also provided on the drill rod side wall, and the monitoring component is connected to the drilling motor signal;

[0007] The inner side walls of the sampling slots are inlaid with driving components for providing rotational drive, the driving components are connected to the monitoring component signals, the output parts of the driving components are fixedly connected to the rotating shaft, the end of the rotating shaft away from the driving component is fixedly connected to a connecting block perpendicular to the rotating shaft, the end of the connecting block away from the rotating shaft is rotatably connected to a sampling rod parallel to the connecting block, the outer wall of the bottom of the sampling rod is provided with a tooth groove, the sampling rod is meshed with a reciprocating gear through the tooth groove, one side of the reciprocating gear is fixedly connected to a fixed rod, the end of the fixed rod away from the reciprocating gear is rotatably connected to the side wall of the sampling slot, and the fixed rod is rotatably connected to The limiting block has a type structure, and the outer wall of the side of the sampling rod is provided with a limiting groove, and the end of the limiting block away from the fixed rod is slidably connected to the limiting groove.

[0008] The technical principle of the above scheme is as follows: When the equipment is working, the drilling motor drives the drill rod and drill bit to rotate and drill downward. When the monitoring component detects copper ore, it sends a signal to the drive component, which starts and drives the sampling rod to unfold and insert it into the copper ore for sampling. As the drive component continues to rotate, the sampling rod is repeatedly fed to sample the horizontal mineral samples. After sampling is completed, the equipment can continue to drill or lift the drill rod to bring the copper ore samples out of the ground for analysis.

[0009] The above scheme has the following beneficial effects:

[0010] 1. This solution, by opening a sampling slot on the side wall of the drill pipe and embedding the drive assembly on the inner side wall of the sampling slot, the drive and connection block, the sampling rod and the transmission coordination of the reciprocating gear, enables the sampling device to achieve multi-directional and multi-position sampling, thereby improving the coverage and efficiency of sampling. At the same time, due to the design of the sampling slot, the sampling rod can reach the predetermined sampling position more accurately, thereby improving the accuracy of sampling.

[0011] 2. In this solution, the driving component in the equipment is connected to the monitoring component signal, and the sampling action can be adjusted in real time according to the monitored copper ore presence, so that the equipment can adapt to different geological conditions and ore body distribution.

[0012] Furthermore, a plurality of spiral sheets are fixedly connected to the outer wall of the drill bit along the circumferential direction.

[0013] Beneficial effects: The design of the spiral blade imitates the principle of the spiral drill, which can lift the cut soil and rock fragments upward along the path of the spiral blade and discharge them out of the hole during the drilling process, reducing the risk of blockage during the drilling process and improving the drilling efficiency.

[0014] Furthermore, a water storage box is fixedly connected to the top side wall of the drill rod, a water storage tank is fixedly connected to the water storage box, the water storage tank is connected to a water pump, the output end of the water pump is connected to a water pipe, the water pipe passes through the side wall of the drive box and the drill rod and extends into the drill bit, and a plurality of water outlets are opened on the side wall of the drill bit.

[0015] Beneficial effects: By delivering water to the drill bit, the soil can be effectively moistened and softened, reducing the resistance of the drill bit during drilling and improving drilling efficiency. In addition, the water flow can reduce the friction between the drill bit and the soil, reduce the wear of the drill bit and drill rod, and extend the service life of the equipment.

[0016] Furthermore, the water delivery pipe is also connected to a plurality of branch pipes corresponding to the positions of the sampling slots respectively, and the branch pipes all penetrate the side wall of the drill pipe and extend from the top of the sampling slot.

[0017] Beneficial effects: Through the branch pipe connected to the water pipe, precise water spraying can be achieved on specific sampling slots, which can more effectively moisten and soften the soil in a specific area and improve drilling efficiency. In addition, the design of the branch pipe helps to discharge rock cuttings from the borehole more effectively, reduce the accumulation of rock cuttings at the bottom of the hole, and avoid increased drilling difficulty caused by rock cuttings accumulation.

[0018] Furthermore, a first bevel gear is fixedly sleeved on several fixed rods, the first bevel gear is meshed with a second bevel gear perpendicular to the first bevel gear, the top end of the second bevel gear is rotatably connected to a rotating cylinder, the end of the rotating cylinder away from the second bevel gear is fixedly connected to the top wall of the sampling groove, and a rotating rod is also fixedly connected at the center of the top surface of the second bevel gear, the top end of the rotating rod penetrates the top wall of the sampling groove and the outer wall of the corresponding branch pipe, and the top end of the rotating rod is fixedly connected to a valve plate located in the corresponding branch pipe, and the valve plate can rotate on the inner wall of the branch pipe.

[0019] Beneficial effect: The design of the second bevel gear converts the rotation of the reciprocating gear into horizontal rotation, and the second bevel gear transmits the rotation to the corresponding valve plate through the rotating rod, realizing a feeding cycle of the sampling rod and a movement of the valve plate rotating to open and the valve rotating to close. Through the design, it can be achieved that the valve is closed when the sampling rod is extended, and the valve is opened to spray water when the sampling rod is retracted, so that the water spraying of the horizontal sampling and the feeding process of the sampling rod are carried out in coordination, which can further reduce water consumption, improve sampling efficiency, and achieve the effect of automatic water spraying.

[0020] Furthermore, the monitoring component includes a natural potential sensor fixedly connected to the outer wall of the drill pipe and a control system, and the natural potential sensor is signal-connected to the control system.

[0021] Beneficial effects: The natural potential sensor can monitor the potential difference data of the underground ore body in real time. These data reflect the changes in the natural potential of the underground ore body and are an important basis for judging the existence of the ore body. In addition, the natural potential sensor signal is connected to the control system to realize real-time data collection and analysis. This real-time monitoring and analysis helps to adjust the drilling strategy in time and improve the drilling efficiency and success rate.

[0022] Furthermore, the bottom of the sampling slot is connected to a collecting slot, and the connecting point between the collecting slot and the sampling slot is close to the opening of the sampling slot.

[0023] Beneficial effect: By arranging the collecting slot at a position close to the opening of the sampling slot, the soil sample scraped from the sampling rod can be collected more effectively, and the loss and scattering of the sample during the collection process can be reduced.

[0024] Furthermore, one end of the sampling rod away from the connection block is a bucket-shaped structure m, and one end of the sampling rod away from the connection block is fixedly connected to a pressure sensor, and the pressure sensor is connected to the control system signal.

[0025] Beneficial effects: The non-uniform thickness design of the sampling rod makes the end away from the connecting block more flexible. This design helps to maintain the stability and durability of the sampling rod under different geological conditions. At the same time, the fixed pressure sensor can monitor the pressure changes during the sampling process in real time to ensure the accuracy of sampling.

[0026] Furthermore, the control system includes a detection and collection unit and a safety protection unit, wherein the detection and collection unit includes:

[0027] The potential acquisition module is used to collect the potential difference data of the underground ore body detected by the natural potential sensor in real time during the drilling process;

[0028] The processing module is used to compare and analyze the collected potential difference data to determine whether there is copper ore at the current drilling depth;

[0029] The drive module is used to pause the drilling motor and start several drive components.

[0030] Beneficial effects: The potential acquisition module can collect the potential difference data of underground ore bodies in real time. These data are the key information for judging whether the ore body exists or not, thus improving the accuracy of detection. The processing module can judge whether there is copper ore at the current drilling depth by comparing and analyzing the collected potential difference data. This intelligent data processing capability reduces human errors and improves the reliability of decision-making. The drive module can automatically control the pause of the drilling motor and the start-up of the drive component according to the analysis results of the processing module, thus realizing automated operation, reducing human intervention and improving operation efficiency.

[0035] Beneficial effects: The safety protection unit can timely detect potential safety risks, such as abnormal formation pressure, by real-time monitoring of the pressure data of the sampling rod, so as to take preventive measures to avoid equipment damage and personal injury.

[0046] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0047] The following is further described in detail through specific implementation methods:

[0048] Embodiment 1:

[0049] As attached Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown: a sampling device for copper ore mineral exploration, including a base 1, a driving box 2 is welded on the base 1, a drilling motor 3 is fixedly connected to the top of the driving box 2 by bolts, the output shaft of the drilling motor 3 is arranged downward, and the output shaft of the drilling motor 3 is coaxially fixedly connected to the drill rod 4 through a coupling, a rod hole 5 is opened at the bottom of the driving box 2, the drill rod 4 can extend out of the bottom of the driving box 2 through the rod hole 5, and a hollow drill bit 6 is welded at the bottom of the drill rod 4. After the drilling sampling point is determined, the base 1 is fixed on the ground, with the rod hole 5 facing the position to be drilled, the drilling motor 3 is started to start rotating, and the power is transmitted to the drill rod 4 through the coupling, so that the drill rod 4 also rotates. At this time, the drill bit 6 starts to drill downward into the underground copper ore layer.

[0050] In order to solve the limitation of sampling in a single vertical borehole, a plurality of sampling grooves 7 are provided on the side wall of the drill rod 4 along its circumference. Figure 3 As shown, a driving assembly for providing rotational drive is embedded on the right side of the inner wall of the sampling slot 7, and the driving assembly includes a servo motor, and the servo motor signal is connected to a control system. The output shaft of the servo motor is coaxially fixedly connected to a rotating shaft 9 through a coupling, and a connecting block 10 of a slot block structure is welded to the left end of the rotating shaft 9. The front end of the connecting block 10 is rotatably connected to a sampling rod 11 parallel to the connecting block 10 through a bearing, and a tooth groove 12 is provided on the outer wall at the bottom of the sampling rod 11, and the sampling rod 11 is meshed with a reciprocating gear 13 through the tooth groove 12; when the servo motor is driven, its output shaft drives the rotating shaft 9 to rotate, and the rotational motion of the rotating shaft 9 is transmitted to the connecting block 10, thereby causing the sampling rod 11 to rotate as well. Due to the design of the tooth groove 12 and the meshing of the tooth groove 12 with the reciprocating gear 13, the rotation of the sampling rod 11 causes the reciprocating gear 13 to move along the opening of the sampling slot 7, thereby realizing the mechanical movement of the sampling rod 11 similar to digging, so that the sampling equipment can sample the lateral copper ore through the sampling rod 11 repeatedly feeding in several sampling slots 7 while simultaneously performing vertical drilling sampling, realizing sampling in multiple directions, collecting data in more dimensions, and providing richer information for the establishment of geological models and mineral assessment. In addition, sampling in multiple directions reduces the number of drillings, thereby saving time and cost.

[0051] A fixed rod 14 is welded at the center of the right side of the reciprocating gear 13. The right end of the fixed rod 14 is rotatably connected to the side wall of the sampling slot 7 through a bearing. The rod body of the fixed rod 14 is rotatably connected to the sampling slot 7 through a bearing. The limit block 15 of the type structure corresponds to the limit slot 16 provided on the front side wall of the sampling rod 11, and the limit block 15 is slidably connected to the limit slot 16 at one end away from the fixed rod 14; during the movement of the sampling rod 11, the design of the fixed rod 14 can make the reciprocating gear 13 rotate in coordination with the movement of the sampling rod 11, while maintaining the relative position of the reciprocating gear 13 and the side wall of the sampling slot 7, and the rod body of the fixed rod 14 is rotatably connected to the sampling rod 11 through the bearing. The limit block 15 of the type structure allows the limit block 15 to rotate on the fixed rod 14. When the connection block 10 rotates from 0° (0° when the connection block 10 is horizontally pointing to the left) to 180°, the sampling rod 11 as a whole follows the swing of the connection block 10 to move outside the sampling slot 7. Under the restriction of the limit block 15, it presents an oblique downward pressing movement. When the connection block 10 rotates from 180° to 360°, the sampling rod 11 as a whole follows the swing of the connection block 10 to move inside the sampling slot 7. Under the restriction of the limit block 15, it presents an oblique upward lifting movement, simulating the action of excavation. Compared with the straight-in and straight-out excavation method, this form of movement, the rotating and swinging excavation movement, can more effectively contact the soil or copper ore, reduce the probability of empty excavation, and improve the excavation efficiency. At the same time, it enables lateral sampling to adapt to the sampling target soil with complex soil hardness, providing a more stable excavation effect.

[0052] In addition, the design of the sliding connection between the limiting groove 16 and the limiting block 15 can also enable the limiting block 15 to slide on the front side wall of the sampling rod 11 while limiting its movement to prevent the sampling rod 11 from deflecting or falling off during rotation or feeding.

[0053] In order to further improve the accuracy of sampling, the side wall of the drill rod 4 is also provided with a monitoring component for detecting the presence of copper ore. The monitoring component includes a natural potential sensor 29 embedded in the outer wall of the drill rod 4. The natural potential sensor 29 is connected to the control system signal. By using the natural potential logging (SP) technology, the lithology of the well wall can be reflected by measuring the changes in the natural electric field in the borehole, and then the formation conditions can be reflected. Therefore, by monitoring the changes in the natural potential, the existence and depth of the copper ore can be identified. When the natural potential sensor 29 detects a change in the specific potential (between -65mV and -360mV) related to the copper ore, the control system can automatically adjust the position of the drill rod 4 and the action of the sampling rod 11 to ensure that sampling is performed at the best position, which improves the pertinence and accuracy of sampling, reduces invalid drilling, and also provides more data support for geological analysis.

[0054] Embodiment 2:

[0055] As attached Figure 5 As shown, the difference from Example 1 is that a plurality of spiral blades 17 integrally formed with the drill bit 6 are fixedly connected to the outer wall of the drill bit 6 along the circumferential direction. During the process of drilling deeper, the sharp edges of the spiral blades 17 can cut soil and rock to form debris, which are then captured by the grooves of the spiral blades 17. As the drill bit 6 continues to rotate, the spiral blades 17 lift the debris upward along the drill rod 4 like a conveyor belt. When the spiral blades 17 lift the debris to the top of the borehole, the debris will be discharged from the borehole and fall on the ground.

[0056] On the one hand, this function of the spiral blade 17 greatly improves the efficiency of the drilling operation. Compared with traditional drilling methods, the spiral blade 17 reduces the extra time and labor required for cleaning the drilled hole, making the drilling process more continuous and efficient.

[0057] On the other hand, the spiral blade 17 not only takes out the debris, but also keeps the original structure of the sample to a certain extent, which is very important for subsequent geological analysis and research. By analyzing the soil and rock samples taken out, the underground geological structure and mineral distribution can be understood more accurately.

[0058] Embodiment 3:

[0059] As attached Figure 2 As shown, the difference from Example 2 is that since the drilling efficiency can be improved by spraying water to moisten the soil during the drilling process, for vertical drilling sampling, a water storage box 18 is welded to the top side wall of the drill rod 4, and a water tank 19 is welded inside the water storage box 18. A water replenishment port for replenishing water is provided on the right side of the water storage tank 19 and the right side of the water storage box 18. The water storage tank 19 is connected to a water pump 20, and the output end of the water pump 20 is connected to a water pipe 21. The end of the water pipe 21 away from the water pump 20 passes through the side wall of the drive box 2 and the drill rod 4 and extends into the drill bit 6. A plurality of water outlets 22 are provided on the side wall of the drill bit 6. In the process of drilling deeper, the water pump 20 transports the water in the water tank 19 to the water outlet 22 of the drill bit 6 through the water pipe 21. The water can be evenly distributed around the drill bit 6 to moisten the surrounding soil, thereby reducing the friction between the drill bit 6 and the soil, reducing the resistance during the drilling process, and enabling the drill bit 6 to penetrate the soil layer more easily, thereby improving the drilling speed. In addition, water spraying can also prevent the soil from drying out and solidifying during the drilling process, especially in drought or hard soil conditions. Water spraying can maintain the fluidity of the soil and avoid drill sticking during the drilling process.

[0060] As for the horizontal sampling process, the body of the water pipe 21 is also connected with a plurality of branch pipes 23 corresponding to the positions of the sampling slots 7. The branch pipes 23 all penetrate the side wall of the drill pipe 4 and extend from the top of the sampling slots 7. The design of the branch pipes 23 allows water to be sprayed directly from the top of the sampling slots 7 to accurately wet the horizontal sampling area, which can more effectively soften the soil, reduce the friction of the sampling rod 11 during the feeding process, and make the moist soil easier to be cut by the sampling rod 11, so that more continuous and representative samples can be collected, providing more accurate data for subsequent geological analysis.

[0061] Since the horizontal sampling is carried out with the assistance of the natural potential sensor 29, the effect of continuous horizontal water spraying and vertical water spraying is repeated. Figure 3 and Figure 4As shown, a first bevel gear 24 is fixedly sleeved on a plurality of fixed rods 14, and the first bevel gear 24 is meshed with a second bevel gear 25 perpendicular to the first bevel gear 24. The top of the second bevel gear 25 is rotatably connected to a rotating cylinder 26 through a bearing, and the end of the rotating cylinder 26 away from the second bevel gear 25 is welded to the inner top wall of the sampling groove 7, and a rotating rod 27 is welded at the center of the top surface of the second bevel gear 25. The top of the rotating rod 27 penetrates the inner top wall of the sampling groove 7 and the outer wall of the corresponding branch pipe 23, and the top of the rotating rod 27 is welded with a valve plate 28 located in the corresponding branch pipe 23, and the valve plate 28 can rotate on the inner wall of the branch pipe 23 to realize the opening and closing of the water flow through the branch pipe 23; since the feeding of the sampling rod 11 is a periodic motion, the rotation period of the reciprocating gear 13 is fixed, which is generally reflected in that the forward rotation realizes the extension of the sampling rod 11, and the reverse rotation realizes the retraction of the sampling rod 11, and the rotation of the reciprocating gear 13 drives The rotation of the first bevel gear 24 is driven, and the design of the second bevel gear 25 converts the rotation of the reciprocating gear 13 into horizontal rotation. The second bevel gear 25 transmits the rotation to the corresponding valve plate 28 through the rotating rod 27, so as to realize a feeding cycle of the sampling rod 11 and realize a movement of the valve plate 28 rotating to open and the valve rotating to close. Through the design, it can be realized that the valve is closed when the sampling rod 11 is extended, and the valve is opened and water is sprayed when the sampling rod 11 is retracted, so that water is sprayed to moisten the soil when the sampling rod 11 is lifted up obliquely and retracted, thereby reducing the hardness of the soil and improving the sampling efficiency; and the water spraying is stopped when the sampling rod 11 is pressed down obliquely and deeply, which reduces the water consumption on the one hand, and prevents the water with potential energy from continuously rushing out to wash the sampled soil off the sampling rod 11 on the other hand, thereby improving the sampling efficiency, so that the water spraying of the horizontal sampling and the feeding process of the sampling rod 11 are coordinated, thereby reducing the water consumption, improving the sampling efficiency, and realizing the effect of automatic water spraying.

[0062] Embodiment 4:

[0063] As attached Figure 3 As shown, the difference from Example 3 is that the bottom of the sampling slot 7 is connected to the collecting slot 8, and the connection between the collecting slot 8 and the sampling slot 7 is close to the opening of the sampling slot 7. When the sampling rod 11 is retracted, due to the presence of the reciprocating gear 13, the retraction movement of the sampling rod 11 presents an upward tilting and shortening process, and the sampled soil carried by the front end of the sampling rod 11 will touch the side wall of the drill rod 4 above the sampling slot 7, similar to the action of scraping off the sampled soil, making the collection process more efficient and reducing the scattering and loss of soil. The design of the opening position of the collection slot 8 and the sampling slot 7 allows the sampled soil to fall directly into the collection slot 8, reducing the operator's additional collection operations.

[0064] Embodiment 5:

[0065] As attached Figure 3As shown, the difference from Example 4 is that the end of the sampling rod 11 away from the connecting block 10 is a bucket-shaped structure. The design of the sampling rod 11 with a bucket-shaped structure, its unique shape is conducive to capturing and retaining more soil samples during the drilling process, similar to a digging bucket, adapting to soil conditions of different hardness and moisture, and can effectively collect samples even in clay or wet soil.

[0066] The sampling rod 11 is designed with non-uniform thickness, in which the end away from the connecting block 10 is designed to be thinner. This special design makes this end of the sampling rod 11 more flexible and adaptable when encountering different geological conditions. Such a structure not only enhances the stability of the sampling rod 11 in complex formations, but also improves its durability, because the thinner end can better absorb and adapt to the fluctuation of underground pressure and reduce the damage caused by the change of geological hardness.

[0067] At the same time, a pressure sensor 30 is fixedly installed at one end of the sampling rod 11 away from the connection block, and the pressure sensor 30 is connected to the control system signal. These sensors can monitor the pressure changes during the sampling process in real time. By transmitting the data of the pressure sensor 30 to the control system in real time, the operator can obtain feedback on the underground pressure conditions in a timely manner, so as to make precise adjustments to the sampling operation. This real-time monitoring function is crucial to ensure the accuracy and safety of sampling, because it allows timely measures to be taken when encountering abnormally high pressure conditions to avoid equipment damage or sampling failure.

[0068] Embodiment 6:

[0069] As attached Figure 6 As shown, the difference from Example 5 is that the control system includes a detection and acquisition unit and a safety protection unit, wherein the detection and acquisition unit includes a potential acquisition module, a processing module and a driving module.

[0070] During the drilling process, the potential acquisition module works continuously to monitor and collect the potential difference data of the underground ore body detected by the natural potential sensor 29 in real time. These data reflect the natural potential changes of the underground ore body and are an important basis for judging the existence of the ore body.

[0071] The processing module receives the potential difference data from the potential acquisition module. Through the built-in algorithm or model, the processing module compares and analyzes the collected data to determine whether there is copper ore at the current drilling depth. If the analysis result shows that there is copper ore, the processing module will send a signal to the drive module.

[0072] After receiving the signal from the processing module, the driving module pauses the drilling motor 3 according to the instruction, and at the same time, starts several servo motors to perform lateral sampling so as to collect the ore sample more accurately.

[0073] The safety protection unit includes a pressure acquisition module, an analysis module and a stop module.

[0074] During the sampling process, the pressure acquisition module continuously monitors and acquires the pressure data of the sampling rod 11 detected by the pressure sensor 30 . The pressure data reflects the pressure changes to which the sampling rod 11 is subjected during the drilling and sampling process.

[0075] The analysis module receives the pressure data from the pressure acquisition module and performs real-time analysis on the data to determine whether there are any abnormal conditions. For example, a sudden increase in pressure may indicate equipment failure or changes in geological structure.

[0076] According to the analysis results of the analysis module, if the stop module detects abnormal pressure data, it will immediately take measures to stop the corresponding servo motor to prevent equipment damage or accidents. At the same time, the stop module can remind the operator to take corresponding safety measures.

[0077] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
