[0001] The present invention relates to the technical field of measurement while drilling (MWD) tools, and particularly to a modular MWD tool for mining applications. Background Art
[0002] In the field of mining MWD, traditional tool equipment has many limitations. In early measurement tools, the connection methods between various functional modules and the drill bit were relatively complex, mostly using welding, riveting, or a large number of cumbersome bolt - nut fastening methods. This has led to extremely inconvenient installation and disassembly of modules during actual use.
[0003] When maintenance is required to replace damaged modules or the drill bit, workers often need to spend a large amount of time and effort removing those complex connection components, which not only seriously affects work efficiency but also increases maintenance costs.
[0004] Moreover, due to the fixed connection method, it is difficult for the equipment to flexibly adjust the functions and quantities of the carried modules according to the changes in different mining MWD work scenarios.
[0005] For example, in mine areas with complex and variable geological structures, multiple different - function modules need to work together to accurately collect and analyze various data, but it is very difficult for traditional equipment to quickly achieve module combination and adjustment. On the contrary, in areas with relatively simple geological conditions, the equipment carries a large number of unnecessary modules, resulting in resource waste and affecting the operation efficiency of the equipment.
[0006] In view of this, the present application is specifically proposed. Summary of the Invention

DETAILED DESCRIPTION
[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0029] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present invention.
[0030] See also Figures 1-7 , the present invention provides a technical solution:
[0031] A modularized measurement while drilling probe 1 for mining includes a measurement probe 1, a drill bit 2 and a module 3. The drill bits 2 are multiple and each is provided with an internal thread. The outer side of the measurement probe 1 is provided with an external thread 101 that matches the internal thread.
[0032] During use, the external thread 101 on the outer side of the measurement probe 1 is threadedly connected to the internal threads on multiple drill bits 2, and the measurement probe 1 and multiple drill bits 2 are assembled together.
[0033] During the drilling process, the measurement probe 1 can measure relevant data during the drilling process, and multiple drill bits 2 work together to perform drilling operations.
[0034] The design of multiple drill bits 2 can improve the drilling efficiency and can complete the drilling task faster compared to a single drill bit 2;
[0035] The measurement probe 1 and the drill bit 2 are threadedly connected, which is convenient for installation and disassembly, facilitating the replacement of damaged components under different working conditions and reducing the maintenance difficulty and cost;
[0036] By combining the measurement probe 1, drill bit 2, etc. through the module 3, it is convenient for overall transportation, storage and management. And during later maintenance or upgrade, different modules 3 can be separately processed according to actual needs, improving the flexibility and scalability of the system.
[0037] A plurality of modules 3 are detachably connected to the measurement probe 1. A jack 4 is provided in the module 3. An installation convex 102 is provided on the top surface of the measurement probe 1. A rotating groove 401 is provided in the installation convex 102. A plug pin 5 is inserted into the jack 4. The plug pin 5 can rotate 90° in the rotating groove 401. A movable plate 7 is slidably connected in the plug pin 5. One end of a guiding column 701 is connected to the top surface of the movable plate 7, and the other end of the guiding column 701 is connected to a pressing plate 703. A threaded rod 702 is rotatably connected to the top surface of the movable plate 7, and the threaded rod 702 is threadedly connected to the plug pin 5.
[0038] During the assembly operation of the mine-used modular measurement probe 1 while drilling, the staff will first place the measurement probe 1 on a suitable operating table and carefully and accurately align the installation convex 102 on the top surface of the measurement probe 1 with the jack 4 provided on the module 3.
[0039] Subsequently, the plug pin 5 is slowly inserted along the axial direction of the jack 4. When the plug pin 5 is completely inserted into the jack 4, the staff manually rotates the plug pin 5 to make it rotate 90° within the rotating groove 401. At this time, the plug pin 5 and the rotating groove 401 form a clamping state, completing the preliminary positioning connection between the module 3 and the measurement probe 1.
[0040] Immediately afterwards, in order to achieve a firm connection between the module 3 and the measurement probe 1, the staff will use a tool to rotate the threaded rod 702.
[0041] Since there is a threaded connection between the threaded rod 702 and the plug pin 5, when the threaded rod 702 starts to rotate, its thread structure will drive the threaded rod 702 to move along its own axial direction.
[0042] In this process, the movable plate 7 rotatably connected to the threaded rod 702 will also move accordingly. Since the movable plate 7 can only slide within the pin 5, the movable plate 7 will drive the guide post 701 and the pressing plate 703 connected to the other end of the guide post 701 to move synchronously.
[0043] As the movable plate 7 moves, the effective length of the pin 5 is adjusted. When the length of the pin 5 is adjusted to exactly enable the module 3 to closely fit the measurement probe 1 and be firmly connected, stop rotating the threaded rod 702. At this time, the module 3 is firmly fixed on the measurement probe 1.
[0044] If it is necessary to increase or decrease the number of modules 3 in subsequent work, or change the position of a certain module 3 on the measurement probe 1, the staff only needs to rotate the threaded rod 702 in the reverse direction.
[0045] When the threaded rod 702 rotates in the reverse direction, it drives the movable plate 7, the guide post 701, and the pressing plate 703 to move in the reverse direction, causing the effective length of the pin 5 to gradually shorten.
[0046] When the pin 5 is shortened to a certain extent, its engagement state with the rotating groove 401 is released. At this time, the module 3 can be easily disassembled from the measurement probe 1, or moved to other positions on the measurement probe 1 and reinstalled according to the above installation steps.
[0047] Through such an operation process, the number of modules 3 can be accurately adjusted and adapted according to the actual requirements of the mine downhole measurement work, and at the same time, the position of each module 3 on the measurement probe 1 can be flexibly and independently selected.
[0048] From the perspective of operation convenience, this connection structure greatly simplifies the installation and disassembly processes of the module 3.
[0049] Compared with some traditional complex connection methods, such as welding or using a large number of complex bolts and nuts for connection, this solution can achieve the installation and disassembly of the module 3 only through the rotation of the pin 5 and the simple rotation of the threaded rod 702. This greatly reduces the operation difficulty of the staff, saves a large amount of installation and disassembly time, and significantly improves the work efficiency.
[0050] In terms of the adaptability of the equipment, the characteristic of being able to flexibly adjust the number of modules 3 has extremely high practical value.
[0051] In different mine downhole measurement work scenarios, the required functions and quantities of the modules 3 often vary.
[0052] For example, in areas with relatively complex geological structures, more modules 3 with different functions may be required to cooperate to complete data collection and analysis work;
[0053] In areas with relatively simple geological conditions, the number of Module 3 can be appropriately reduced to avoid waste of resources.
[0054] With this solution, the staff can quickly and conveniently adapt and adjust the number of Module 3 according to the changes in actual work tasks and the environment, so that the entire downhole measurement tool 1 with modularized Module 3 can better meet different work requirements, greatly improving the practicality and adaptability of the equipment.
[0055] For some special modules 3 that are sensitive to power interference, the function of being able to select the location of Module 3 by itself in this solution is particularly important.
[0056] During the downhole measurement process in mining, certain intensity of electromagnetic interference often occurs around the power supply equipment, and the working performance of some special modules 3 may be seriously affected by this electromagnetic interference, resulting in inaccurate measurement data or even the module 3 being unable to work properly.
[0057] With this solution, the staff can accurately adjust these special modules 3 that are sensitive to power interference to positions far from the power supply, effectively avoiding the adverse effects of power interference on the working performance of the module 3.
[0058] In this way, it can ensure that the entire downhole measurement tool 1 system with modularized Module 3 can still maintain a stable and accurate operating state in complex working scenarios, significantly improving the reliability of the equipment in various complex working environments.
[0059] The top surface of the threaded rod 702 passes through the pressing plate 703, and a screwing cap 704 is fixedly connected to the top surface of the threaded rod 702. A cross groove is provided on the top surface of the screwing cap 704.
[0060] During assembly, the staff first need to select the appropriate number and type of Module 3 according to the requirements of the actual measurement task. These Module 3 include functional modules with different functions and a power supply module that provides power support for the entire system.
[0061] When the Module 3 is initially positioned and installed on the downhole measurement tool 1, that is, after the plug pin 5 completes the rotational positioning in the jack 4 and the rotating groove 401, it enters the fastening stage of the Module 3.
[0062] At this time, the staff will take out a suitable cross screwdriver and accurately insert the screwdriver tip into the cross groove on the top surface of the screwing cap 704.
[0063] Then, the staff exerts force by hand and rotates the screwdriver clockwise. Since there is a firm fixed connection between the screwing cap 704 and the threaded rod 702, the screwing cap 704 will rotate synchronously, and then drive the threaded rod 702 to start rotating.
[0064] Because there is a precise threaded connection structure between the threaded rod 702 and the pin 5, as the threaded rod 702 rotates, it will move along its own axial direction. During this process, the movable plate 7 rotatably connected to the threaded rod 702 will also slide along a specific track inside the pin 5.
[0065] At the same time, the movable plate 7 will also drive the guide post 701 connected thereto and the pressing plate 703 located at the other end of the guide post 701 to move together. Through such a linkage mechanism, the effective length of the pin 5 can be precisely adjusted, and finally the module 3 can be firmly and stably fixed on the measurement probe 1.
[0066] From the dimension of operation convenience, turning the cross slot specially designed on the top surface of the cover 704 provides great convenience for the staff to rotate the threaded rod 702.
[0067] In the actual working scenario, a cross screwdriver is a very common and easily accessible tool. This design enables the staff to easily operate the threaded rod 702 without the need to use special and complex tools.
[0068] Greatly reduces the operation difficulty of rotating the threaded rod 702, makes the installation and disassembly process of the module 3 smoother and more efficient, effectively saves working time, and significantly improves the overall work efficiency.
[0069] The multiple modules 3 are respectively multiple functional modules and a power supply module. The top surface and the bottom surface of the functional module are respectively provided with a connecting convex 301 and a connecting concave 302, and the connecting convex 301 and the connecting concave 302 are both provided with energized contacts 303 corresponding in position. The bottom surface of the power supply module is provided with a connecting concave 302.
[0070] When multiple functional modules need to be combined, the staff will align the connecting convex 301 protruding from the bottom of one functional module and embed it into the connecting concave 302 recessed from the top of another functional module.
[0071] It should be noted that inside the connecting convex 301 and the connecting concave 302, energized contacts 303 corresponding precisely in position are both provided.
[0072] When the connecting convex 301 and the connecting concave 302 are perfectly fitted, these energized contacts 303 will contact and conduct with each other, thereby building a stable circuit connection between the functional modules, enabling the modules with different functions to work together according to the system preset program and jointly complete complex downhole measurement-while-drilling tasks.
[0073] And the power supply module, as the energy core of the whole system, its bottom surface is also provided with a connecting concave 302 adapted to the connecting convex 301 of the functional module.
[0074] During assembly, the connecting recess 302 of the power module can be seamlessly docked with the connecting protrusion 301 of the functional module. Through the power-on contact 303, the electrical energy stored in the power module can be smoothly transmitted to the connected functional module, thereby providing a continuous and stable power supply for the entire device and ensuring the normal operation of all parts of the system.
[0075] At the level of connection and function realization, the unique cooperative design of the connecting protrusion 301 and the connecting recess 302 of the functional module, as well as the ingenious use of the power-on contact 303, lay a solid foundation for the function expansion and flexible configuration of the system.
[0076] In the complex and changeable working environment of mine measurement-while-drilling, different measurement tasks often require different functional modules to work together.
[0077] With this connection method, the staff can freely and flexibly select various functional modules for combination according to the actual measurement needs, just like building blocks.
[0078] For example, when conducting a detailed exploration of the geological structure, a module with high-precision geological data collection function can be connected to a module good at data analysis and processing;
[0079] When monitoring the environmental parameters in the mine, the environmental monitoring module can be combined with the data transmission module.
[0080] This high degree of flexibility greatly improves the functional diversity of the system and its adaptability to different working scenarios.
[0081] At the same time, the power module uses the same connection method as the functional module to connect and supply power to other modules 3, which not only ensures the stability and reliability of the power supply of the entire system, but also the unified connection structure greatly simplifies the assembly process of the entire system.
[0082] During the assembly process, the staff does not need to spend extra time and effort to adapt to different connection methods, reducing the error probability during assembly and the risk of system failures caused by improper connections, providing strong guarantee for the stable operation of the device in complex working environments.
[0083] A positioning groove 6 is provided in the mounting protrusion 102. A positioning block 602 is slidably connected in the positioning groove 6. A spring 604 is provided on the back of the positioning block 602. A positioning hole 501 adapted to the positioning block 602 is provided at one end of the bolt 5.
[0084] A communication port 601 is provided on the top surface of the positioning groove 6. A dial rod 603 is slidably connected in the communication port 601. The dial rod 603 is in a T shape.
[0085] A chamfer is provided on one side of the positioning block 602 facing the jack 4.
[0086] When the bolt 5 is inserted into the jack 4 and rotated 90° into the rotating groove 401, the bolt 5 will squeeze the positioning block 602.
[0087] There is a spring 604 on the back of the positioning block 602. When being squeezed, the positioning block 602 overcomes the elastic force of the spring 604 and slides in the positioning groove 6.
[0088] When the bolt 5 rotates into place and its positioning hole 501 aligns with the positioning groove 6, at this time the spring 604 rebounds and pushes the positioning block 602 into the positioning hole 501, thereby performing secondary positioning on the bolt 5 to ensure that the bolt 5 will not rotate randomly, making the connection between the module 3 and the measuring probe 1 more stable.
[0089] If the module 3 needs to be disassembled, the communication port 601 on the top surface of the positioning groove 6 comes in handy.
[0090] The T-shaped lever 603 is slidably connected in the communication port 601. Just push the lever 603, and the lever 603 will squeeze the positioning block 602 out of the positioning hole 501, releasing the positioning of the bolt 5 and facilitating subsequent disassembly.
[0091] In addition, a chamfer is provided on one side of the positioning block 602 facing the jack 4, so that when the bolt 5 is inserted and rotated, it can more smoothly squeeze the positioning block 602, reduce jamming, and improve the smoothness of the operation.
[0092] First of all, the positioning structure composed of the positioning block 602 and the spring 604 enhances the reliability of the connection between the module 3 and the measuring probe 1, reducing the risk of connection loosening caused by the rotation of the bolt 5.
[0093] Secondly, the design of the T-shaped lever 603 makes the disassembly operation simple and easy for the staff to complete.
[0094] Finally, the chamfer design of the positioning block 602 optimizes the installation experience and improves the overall efficiency of installing and disassembling the module 3.
[0095] An activity cavity 502 is provided in the bolt 5. The activity plate 7 is slidably connected in the activity cavity 502. A guiding hole 503 is provided on the top surface of the activity cavity 502. The guiding column 701 is slidably connected in the guiding hole 503. There are four guiding columns 701 respectively arranged at the four corners of the top surface of the activity plate 7. A threaded port 504 is provided at the center of the top surface of the activity cavity 502. The threaded rod 702 is threadedly connected to the bolt 5 through the threaded port 504.
[0096] When the threaded rod 702 is rotated, because the threaded rod 702 is threadedly connected to the bolt 5 through the threaded port 504, according to the principle of screw drive, the rotation of the threaded rod 702 will be converted into axial movement.
[0097] Since the movable plate 7 is slidable in the movable cavity 502 and the guide posts 701 at the four corners of the top surface of the movable plate 7 slide in the guide holes 503, the axial movement of the threaded rod 702 will push the movable plate 7 to slide in the movable cavity 502.
[0098] The sliding of the movable plate 7 changes the effective working length of the bolt 5, thereby realizing the adjustment of the fixed state of the module 3. When the length of the bolt 5 is appropriate, the module 3 can be fastened, and when the length is shortened, the module 3 can be loosened for disassembly.
[0099] First of all, the four guide posts 701 are distributed at the four corners of the top surface of the movable plate 7, playing a good guiding and stabilizing role.
[0100] This can ensure the smooth sliding of the movable plate 7 in the movable cavity 502, avoid deviation or jamming, thereby ensuring the accuracy and stability of the process of adjusting the length of the bolt 5, and making the installation and disassembly operations of the module 3 more reliable.
[0101] Secondly, a threaded opening 504 is provided at the center of the top surface of the movable cavity 502. This structural design is compact and the space is utilized reasonably, and the connection between the threaded rod 702 and the bolt 5 is cleverly arranged therein.
[0102] Moreover, the threaded connection method is easy to operate, and the force required to rotate the threaded rod 702 is relatively small, reducing the labor intensity of the operator and improving the work efficiency.
[0103] Generally speaking, this solution improves the convenience of installing and disassembling the module 3, ensures the stability of the equipment connection, and has high practical value in practical applications.
