Description

Technical Field

[0001] This invention relates to the field of borehole water inrush control technology, and in particular to a water inrush control device for near-horizontal directional boreholes in mines. Background Technology

[0002] In mine tunneling or resource exploration, near-horizontal directional drilling is an advanced technology for advance detection and mitigation. However, when the borehole exposes a water-rich area or water-conducting structure, borehole water inrush accidents are prone to occur, seriously threatening safe mine production. Rapid and effective sealing of such water inrushes is a crucial aspect of mine water hazard prevention.

[0003] Currently, grouting technology is commonly used for water inrush control, which involves injecting grout into the borehole through a drill rod, and forming a water barrier after it solidifies. However, existing grouting devices and methods have the following significant technical drawbacks in practical applications:

[0004] Lack of reliable anchoring structure and poor positioning accuracy: Conventional grouting pipes (or drill rods) lack an effective in-hole anchoring mechanism after being inserted into the borehole. During high-pressure grouting, the reaction force of the grout can easily cause the grouting pipe to move, shift, or even be flushed out of the borehole. This not only prevents the sealing grout from accurately targeting the water inrush section, affecting the sealing effect, but may also lead to sealing operation failure or even a larger safety accident.

[0005] Poor grouting effect and uneven grout distribution: Traditional grouting pipe outlets are mostly fixed or simple diversion types, with the grout flowing out under static or low pressure. This method cannot ensure that the grout diffuses and penetrates evenly and effectively in the circumferential and radial fractures of the borehole. The grout often concentrates and flows away along the path of least flow resistance, forming "grout channeling," while fractures in other areas are not fully filled. This results in an incomplete seal with low strength and poor durability, posing a risk of re-inrush water. Summary of the Invention

[0006] The purpose of this invention is to provide a water inrush control device for near-horizontal directional drilling in mines, which aims to solve or improve at least one of the above-mentioned technical problems.

[0024] Optionally, the rotary ejection mechanism includes:

[0025] A short gear is rotatably connected inside the first connecting tube, and the short gear is coaxially connected to the secondary bevel gear;

[0026] A long gear is rotatably connected to the guide rod, and the long gear meshes with the short gear;

[0040] Optionally, a tapered drill bit is connected to one end of the first connecting pipe.

[0041] The present invention discloses the following technical effects:

[0042] This invention utilizes multiple guide rods in conjunction with an elastic mechanism to automatically center the device during its pushing process, ensuring stable movement. Upon reaching the designated grouting and sealing position, the first drive mechanism is activated. This, through a first transmission mechanism, drives multiple anchoring spikes to extend radially and forcefully penetrate the inner wall of the borehole. This process creates a powerful mechanical anchoring structure within the borehole, firmly locking the entire device inside. This anchoring structure effectively resists the high-pressure reaction force during grouting, preventing device displacement and ensuring precise positioning and stability during the grouting and sealing process. This lays a solid foundation for high-quality sealing.

[0043] After anchoring, the grouting system delivers grout to multiple nozzles through grouting pipes and connecting mechanisms. Simultaneously, a second drive mechanism drives a rotating ring to rotate at a constant speed via a second transmission mechanism. Multiple nozzles mounted on the rotating ring then rotate 360°, spraying the grout into the borehole wall and surrounding fractures in a dynamic rotating jet manner. This rotating jetting mode greatly improves the uniformity of grout diffusion, avoids the defects of fixed-point grouting, and allows the grout to more effectively penetrate and fill fracture networks in different directions, thereby forming a tightly wrapped, large-volume, high-strength, uniformly solidified body, significantly improving the reliability and durability of the sealing.

[0050] Existing Chinese patent CN110344784A discloses a water inrush control device for near-horizontal directional drilling in mines, including a grout stop plug, a short section, a pressure tube, and a drill rod. The grout stop plug consists of a central tube, a capsule, a front tray, and a rear tray, with a tapered drill bit fixedly connected to the front tray. The pressure tube is located inside the drill rod, with its front end movably passing through the end of the drill rod and connecting to the rear tray. A grouting pipe is also installed inside the drill rod, with a grout outlet hole on the outer wall of the front end of the drill rod. The end of the grouting pipe passes through and is fixed to the grout outlet hole. The use of a tapered drill bit makes the front tray of the grout stop plug less susceptible to damage. Firstly, by placing the pressure pipe inside the drill rod, the pressure pipe is prevented from getting stuck in the borehole, thus avoiding the drill rod from being jammed. This allows the grout stop plug to be smoothly delivered into place in the near-horizontal borehole. Utilizing the space inside the drill rod, an injection pipe is added. This not only retains the original function of sealing and modifying the limestone aquifer with cement grout at the front end of the grout stop plug, but also creatively provides a cement grout sealing function for the annular space outside the drill rod at the rear end of the grout stop plug. There is no longer any concern about fatigue leakage of the grout stop plug. During the process of controlling water inrush in the borehole, continuous grouting can be carried out for a long time, providing a guarantee for the control of water inrush in the limestone aquifer.

[0051] 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.

[0052] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0053] Reference Figures 1 to 4 This invention provides a water inrush control device for near-horizontal directional drilling in mines, comprising:

[0054] The first connecting pipe 1 and the second connecting pipe 2 are detachably connected by an electromagnetic mechanism. The second connecting pipe 2 is used to connect to the drill pipe. The second connecting pipe 2 is equipped with a first driving mechanism, a second driving mechanism and a grouting pipe 3. The grouting pipe 3 is used to connect to the grouting system.

[0055] Multiple guide rods 4 are respectively arranged circumferentially on the side wall of the first connecting pipe 1 through an elastic mechanism. One end of the guide rod 4 is arc-shaped to abut against the inner wall of the borehole. The multiple guide rods 4 are used to keep the first connecting pipe 1 in the middle position of the borehole axis.

[0056] Multiple anchoring spikes 5 are respectively installed in multiple guide rods 4. The multiple anchoring spikes 5 are detachably connected to the first drive mechanism through the first transmission mechanism. The first drive mechanism can drive the first transmission mechanism so that the multiple anchoring spikes 5 can be used to insert into the inner wall of the borehole.

[0057] A rotating ring 6 is mounted on the first connecting pipe 1. The rotating ring 6 is detachably connected to the second driving mechanism via the second transmission mechanism. The second driving mechanism can drive the rotating ring 6 to rotate via the second transmission mechanism. The rotating ring 6 is circumferentially provided with multiple nozzles 7. The multiple nozzles 7 are detachably connected to the grouting pipe 3 via a connecting mechanism.

[0058] Multiple guide rods 4, in conjunction with an elastic mechanism, keep the first connecting pipe 1 in a centered position as it moves through the borehole. Once it reaches the designated position, the first drive mechanism drives the first transmission mechanism, causing multiple anchoring spikes 5 to pierce into the inner wall of the borehole to form an anchoring structure. Then, grouting is performed through the grouting system via the grouting pipe 3, the connecting mechanism, and multiple nozzles. Simultaneously, the second drive mechanism drives the second transmission mechanism, causing the rotating ring 6 to rotate and form a rotary jet. This achieves the integrated integration of three core functions: automatic centering, strong anchoring, and rotary jetting, solving the fundamental problems of existing technologies.

[0059] Furthermore, the grouting system is existing technology and will not be described in detail here.

[0060] In one embodiment of the present invention, the electromagnetic mechanism includes:

[0061] The magnetic accumulator 8 is connected to the first connecting tube 1;

[0062] The electromagnetic attraction device 9 is installed on the second connecting pipe 2 and is used to detachably connect to the magnetic attractor 8.

[0063] The first connecting pipe 1 and the second connecting pipe 2 are connected by electromagnetic attraction using a magnetic chuck 8 and an electromagnetic attraction device 9, enabling rapid docking and separation of the device. This not only simplifies the operation process in complex downhole environments and improves efficiency, but also allows the second connecting pipe 2 and its internal drive mechanism to be recycled after grouting, reducing equipment costs and enabling the reuse of core functional components.

[0064] In one embodiment of the present invention, the elastic mechanism includes:

[0065] Mounting bracket 10 is fixedly connected to guide rod 4;

[0066] Multiple elastic telescopic rods 11 are connected between the mounting bracket 10 and the inner wall of the first connecting pipe 1.

[0067] The guide rod 4 is supported by multiple elastic telescopic rods 11, which enables the device to have self-adjustment capability. During the pushing process, no matter how small the borehole diameter changes or how slightly it bends, the elastic mechanism can ensure that the guide rod 4 is always in contact with the borehole wall, so that the core part of the device is stably in the center of the borehole, avoiding scraping and jamming with the borehole wall, ensuring that it can reach the designated position smoothly, and providing a uniform circumferential space for subsequent anchoring.

[0068] In one embodiment of the present invention, the first driving mechanism includes:

[0069] The first motor 12 is fixedly installed on the second connecting pipe 2, and the output shaft of the first motor 12 is connected to the first rectangular connecting sleeve 13.

[0070] The first rectangular connector 14 is connected to the first transmission mechanism and is used to insert into the first rectangular connecting sleeve 13.

[0071] The transmission method using the first motor 12 in conjunction with the first rectangular connecting sleeve 13 and the first rectangular connector 14 is simple and reliable. The rectangular mating surface can transmit large torque and there is no circumferential slippage, ensuring sufficient power when driving the anchoring spike 5. At the same time, the plug-in design facilitates the rapid transmission and disconnection of power.

[0072] In one embodiment of the present invention, the first transmission mechanism includes:

[0073] The first transmission rod 15 is rotatably connected inside the first connecting pipe 1. The first transmission rod 15 is coaxially connected to the first rectangular connector 14. A main bevel gear 16 is fixedly connected to the first transmission rod 15.

[0074] Multiple secondary bevel gears 17 mesh with the main bevel gear 16, and the multiple secondary bevel gears 17 are respectively driven by multiple anchoring spikes 5 through a rotary ejection mechanism.

[0075] The unidirectional rotational motion of the central shaft is efficiently converted into multiple radial rotational motions by the main bevel gear 16 and multiple auxiliary bevel gears 17, enabling a single power source to synchronously drive multiple anchoring spikes 5. This design ensures that all anchoring spikes 5 can operate simultaneously and synchronously, resulting in a uniform distribution of anchoring force and avoiding device skew caused by unilateral anchoring.

[0076] In one embodiment of the present invention, the rotary ejection mechanism includes:

[0077] The short gear 18 is rotatably connected inside the first connecting tube 1, and the short gear 18 is coaxially connected to the secondary bevel gear 17;

[0078] The long gear 19 is rotatably connected to the guide rod 4, and the long gear 19 meshes with the short gear 18;

[0079] A rectangular rod 20 is coaxially connected to a long gear 19;

[0080] A rectangular telescopic cavity 21 is formed in the anchoring spike 5, and the rectangular telescopic cavity 21 slides with the rectangular rod 20.

[0081] A threaded through hole 22 is opened through the guide rod 4, and the anchoring spike 5 is threadedly engaged with the threaded through hole 22.

[0082] The engagement of the long gear 19 and the short gear 18 maintains the transmission connection during the displacement of the guide rod 4. The rotational motion is transmitted to the rectangular rod 20 through the long gear 19 and the short gear 18. Then, by utilizing the engagement of the anchoring spike 5 and the threaded through hole 22, the rotational motion is converted into the pushing motion of the anchoring spike 5, which causes the anchoring spike 5 to rotate and slide along the threaded through hole 22. This allows the anchoring spike 5 to overcome the resistance of the rock strata and reliably rotate and penetrate the hole wall.

[0083] In one embodiment of the present invention, the second driving mechanism includes:

[0084] The second motor 23 is fixedly installed on the second connecting pipe 2, and the output shaft of the second motor 23 is connected to the second rectangular connecting sleeve 24.

[0085] The second rectangular connector 25 is connected to the second transmission mechanism and is used to insert into the second rectangular connector sleeve 24.

[0086] Similar to the first drive mechanism, its rectangular transmission method provides a stable and reliable torque source for the rotating ring, ensuring that the nozzle can rotate smoothly and continuously, and is easy to disassemble.

[0087] In one embodiment of the present invention, the second transmission mechanism includes:

[0088] The second transmission rod 26 is rotatably connected inside the first connecting pipe 1. The second transmission rod 26 is coaxially connected to the second rectangular connecting head 25. A drive spur gear 27 is fixedly connected to the second transmission rod 26.

[0089] Driven gear ring 28 is connected to rotating ring 6 and meshes with driving spur gear 27.

[0090] The transmission method of using a driving spur gear 27 and a driven gear ring 28 converts the high-speed rotation of the driving spur gear 27 into the rotation of the driven gear ring 28. The transmission ratio is stable and the power output is smooth, which is very suitable for driving a rotating ring with a large load to rotate at a constant speed, thus ensuring the uniformity of the spray.

[0091] In one embodiment of the present invention, the communication mechanism includes:

[0092] A fixed pipe 29 is fixedly connected inside the first connecting pipe 1. An insert pipe 30 is fixedly connected to and communicates with the fixed pipe 29. The insert pipe 30 is used to be inserted into the grouting pipe 3.

[0093] Rotary connecting pipe 31 is rotatably connected to fixed pipe 29;

[0094] The main connecting pipe 32 is connected to the rotating connecting pipe 31 and is connected to the fixed pipe 29. The main connecting pipe 32 is connected to multiple nozzles 7 one by one through multiple auxiliary connecting pipes 33.

[0095] Through the ingenious design of the fixed pipe 29 and the rotating pipe 31, a dynamic sealed connection is achieved between the stationary grouting pipe 3 and the rotating nozzle 7. This structure ensures continuous and leak-free delivery of grout while completely not interfering with the rotational movement of the rotating ring, making it the core basic component for realizing the rotating jet function.

[0096] Furthermore, the first transmission rod 15 passes through the rotating connecting pipe 31 and the fixed pipe 29 in sequence, and is rotated and sealed by a sealing bearing.

[0097] In one embodiment of the present invention, a tapered drill bit 34 is connected to one end of the first connecting pipe 1. The tapered drill bit 34 is provided at the front end of the first connecting pipe 1, so that the device has a certain self-drilling capability, which can break through a small number of obstacles or deposits in the hole, improve the device's passability in complex hole conditions, and ensure that it can reach deeper or more challenging water inrush sealing positions.

[0098] In the description of this invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0099] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
