Description

Technical Field

[0001] This application relates to the field of polar exploration technology, and in particular to a polar ice drilling device. Background Technology

[0002] Polar environmental exploration is of critical value for resource development, climate change research and ecological monitoring, and is mainly carried out by drilling to extract ice cores.

[0003] Related technologies typically rely on icebreakers to transport drilling equipment to the work site. Limited by the vessel's mobility, the exploration area is strictly confined to the ice surface, preventing direct penetration drilling into the water beneath the ice. Furthermore, ice surface movement, underwater stabilization, and drilling operations must be performed by separate equipment: ice surface movement depends on ship-mounted tracks or wheeled platforms, which lack underwater adaptability; underwater operations require manual operation of portable drilling devices to extract ice cores or the deployment of additional underwater robots, resulting in lengthy equipment switching times and fragmented operational processes. More importantly, in ice-water transition zones, such as floating ice areas or semi-submerged states, it is difficult to balance stability and drilling efficiency. Ice surface movement mechanisms cannot cope with underwater current interference, underwater propulsion drilling lacks ice surface positioning capabilities, and fixed drilling modes cannot achieve vertical drilling in the water beneath the ice, forcing operators to frequently adjust equipment or interrupt tasks. Summary of the Invention

[0004] This application provides a polar ice drilling device to solve the problem in related technologies that polar exploration and monitoring operations cannot simultaneously meet the requirements of ice surface movement, ice surface drilling, and underwater drilling, which reduces the efficiency of polar environment exploration and increases safety risks.

[0006] In some embodiments, the chassis drive device includes: a chassis frame on which at least two sets of transmission gears are connected, the track being connected between two gears on the same side of the two sets of transmission gears, so that the track is arranged symmetrically from left to right; and a first motor connected to any one of the sets of transmission gears.

[0007] In some embodiments, the steering mechanism includes: a universal joint, one end of which is connected to the movable base and the other end of which is connected to the drill bit; a second motor, a mounting bracket rotatably connected to a bearing on the universal joint, the second motor being connected to the mounting bracket, and the output shaft of the second motor being fixed to the bearing of the universal joint.

[0008] In some embodiments, the water storage controller includes: a solenoid valve disposed within the water storage chamber; and a water pipe, wherein the solenoid valve includes two through holes, one end of the water pipe is connected to one of the through holes, and the other end is connected to the outside of the water storage chamber.

[0009] In some embodiments, a pressure sensor is also provided in the water storage chamber. The pressure sensor is connected to the solenoid valve and is used to monitor the water pressure in the water storage chamber in order to control the opening and closing of the solenoid valve according to the water pressure information.

[0010] In some embodiments, the gas storage controller includes an air compressor pump connected to the gas storage chamber for injecting air into the gas storage chamber.

[0011] In some embodiments, the top of the drainage control device is provided with a support, and the plurality of propellers include: a vertical main propeller connected to the top corner of the support; and a horizontal thrust propeller connected to both sides of the support.

[0012] In some embodiments, the sensing and control system includes a depth sensor and a controller, the controller being connected to the depth sensor and used to control the attitude of the vertical main propeller and the horizontal thruster propeller based on current depth information.

[0013] In some embodiments, the sealed container is connected to a lighting system.

[0014] In some embodiments, a camera system is also connected inside the gas storage chamber, and an observation port is provided at one end of the sealed container, with the lens of the camera system facing the observation port.

[0015] The beneficial effects of the technical solution provided in this application include: This application provides a polar ice drilling device that integrates tracks and a chassis drive unit, an adjustable drilling device, a drainage control system, a vector propeller unit, and multiple functions. Its overall design considers low-temperature adaptability, modular reliability, and operational safety in polar environments, possessing multiple capabilities such as autonomous positioning, multi-angle drilling, underwater hovering, and drainage operations. After the device is activated, it initially achieves mobile deployment on the ice surface through track movement. With the help of an independent chassis drive unit, it performs operations such as forward movement, changing direction, and adjusting its position. Upon reaching the target drilling point, the drilling device adjusts its attitude using a steering mechanism. Depending on actual needs, it can select between two drilling modes: "horizontal drilling" and "vertical downward drilling." If it is at the edge of floating ice or needs to penetrate the ice surface downwards, the drill bit structure can rotate to a vertical orientation, using the track's thrust as a reaction force to maintain the stability of vertical drilling. During drilling, the drill bit rotates and cuts, slowly sinking downwards to achieve efficient and stable drilling. If the area beneath the ice is water, the vector propeller device can be activated, providing three-dimensional attitude control capabilities to achieve underwater hovering, positioning, and propulsion, assisting the device in flexible deployment and retrieval operations in complex ice and water environments. The drainage control device compresses gas through a gas storage controller and draws water through a water storage controller to remove accumulated water or ice debris. This technical solution overcomes the surface limitations of icebreaker operations, enabling continuous penetrating drilling from the ice surface to the water beneath the ice. Furthermore, it eliminates the drawbacks of traditional technologies where ice movement, underwater stabilization, and drilling operations require separate equipment, significantly shortening the workflow and avoiding efficiency losses due to equipment switching. Especially in complex transition zones such as floating ice areas, it maintains vertical drilling accuracy and system stability, thus providing efficient and reliable all-scenario operational capabilities for polar resource exploration and environmental monitoring.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] This application provides a polar ice drilling device that can solve the problem in related technologies that polar exploration and monitoring operations cannot simultaneously meet the requirements of ice surface movement, ice surface drilling, and underwater drilling, thereby reducing the efficiency of polar environment exploration and increasing safety risks.

[0021] Reference Figure 1-6A polar ice drilling device includes: a mobile base 1, a drilling device 2, a drainage control device 3, and a vector propeller device 4. The mobile base 1 includes tracks 10 and a chassis drive unit 11. The chassis drive unit 11 is connected to the tracks 10 and drives the tracks 10 to move, enabling movement across the ice surface. The drilling device 2 includes a steering mechanism 20 and a drill bit 21. One end of the steering mechanism 20 is connected to the mobile base 1, and the other end is connected to the drill bit 21. The steering mechanism 20 is used to adjust the drilling direction of the drill bit 21. The drill bit 21 is made of high-strength alloy and can penetrate ice layers, high-density snow layers, and ice-water transition zones. The drainage control device 3 includes a sealed tank 30 and a piston plate 31. The sealed tank 30 is connected to the top of the mobile base 1. Made of titanium alloy, the piston plate 31 is movably connected to the sealed tank 30 by the drive of the cylinder 6. The cylinder 6 is installed in the air storage chamber 33. The piston plate 31 divides the sealed tank 30 into a water storage chamber 32 and an air storage chamber 33. The water storage chamber 32 is equipped with a water storage controller 34 for adjusting the amount of water inside, and the air storage chamber 33 is equipped with an air storage controller 35 for adjusting the amount of air inside. The vector propeller device 4 is connected to the top of the sealed tank 30. The vector propeller device 4 includes several propellers 40 and a sensing and electronic control system 41. The sensing and electronic control system 41 is connected to several propellers 40 and is used to control the motion attitude of several propellers 40.

[0022] In this application, during application, the tracks 10 and chassis drive device 11 of the mobile base 1 first autonomously move to the target point on the ice surface, overcoming the range limitations of the icebreaker; when approaching the ice-water transition zone, the drainage control device 3 is activated, the piston plate 31 moves to adjust the volume of the water storage chamber 32 and the air storage chamber 33, the water storage controller 34 precisely injects or discharges the water in the water storage chamber 32 of the sealed tank 30, and at the same time the air storage controller 35 adjusts the air pressure in the air storage chamber 33, dynamically changing the overall buoyancy of the device, so that the device sinks or floats smoothly, while the sensor and electronic control system 41 of the vector propeller device 4 receives water flow and sensor data in real time, and coordinates the thrust direction and intensity of each propeller 40 to provide underwater propulsion, precise positioning and anti-water flow interference. Force ensures the device remains vertically stable in the sub-ice water. At this time, the steering mechanism 20 of the drilling device 2 flexibly adjusts the angle and depth of the high-strength alloy drill bit 21 according to the preset path or real-time feedback, penetrating the ice layer, high-density snow layer and fragile ice-water transition zone. During this period, the drainage control device 3 and the vector propeller 40 work closely together: the water volume of the water storage chamber 32 is adjusted to finely adjust the center of gravity, and the attitude of the propeller 40 compensates for water flow disturbances to prevent the drill bit 21 from deviating. The whole process does not require equipment switching. After the moving base 1 provides initial positioning on the ice surface, the drainage and propeller 40 systems seamlessly take over the underwater operation. The steering mechanism 20 dynamically responds to changes in drilling resistance, and finally realizes the integrated operation of traveling from the ice surface, stably crossing the transition zone and vertically drilling in the sub-ice water.

[0023] In this application, the chassis drive device 11 includes a chassis frame 110 and a first motor 112. At least two sets of transmission gear sets 111 are connected to the chassis frame 110. Each set of transmission gear sets 111 includes a rotating gear and a driven gear. The track 10 is connected between two gears on the same side of the two sets of transmission gear sets 111 so that the track 10 is arranged symmetrically from left to right. The first motor 112 is connected to any set of transmission gear sets 111, specifically to the driving gear. The first motor 112 includes, but is not limited to, a drive motor, and drives independently on both sides.

[0024] The chassis frame 110 serves as a rigid support structure, on which at least two sets of transmission gear sets 111 are installed, so that the tracks 10 are symmetrically connected to the gears on the same side, forming a balanced force distribution layout. When the first motor 112 starts, the drive gear is directly connected to the motor output shaft, and the torque is efficiently transmitted to the driven gear through gear meshing, driving the tracks 10 to circulate. In practical applications, when the device travels on ice, the independent dual-side drive allows the left and right motors to independently adjust the speed or direction. Combined with the symmetrical track 10 arrangement, it can compensate for uneven force caused by ice cracks, soft snow layers, or sloping terrain in real time, avoiding slippage or rollover on one side.

[0025] In this application, the steering mechanism 20 includes a universal joint 200 and a second motor 201. One end of the universal joint 200 is connected to the movable base 1, and the other end is connected to the drill bit 21. A mounting bracket 202 is rotatably connected to the bearing 2000 on the universal joint 200. The second motor 201 is connected to the mounting bracket 202, and the output shaft of the second motor 201 is fixed to the bearing 2000 of the universal joint 200. One end of the universal joint 200 is rigidly connected to the movable base 1 to provide a stable reference, and the other end is connected to the high-strength alloy drill bit 21. The mounting bracket 202 rotatably connected to the bearing 2000 serves as the carrier of the second motor 201. When the second motor 201 is started, the output shaft directly drives the bearing 2000 to rotate, forcing the universal joint 200 to deflect flexibly in the horizontal and vertical planes, thereby changing the drilling direction of the drill bit 21 in real time.

[0026] In this application, the water storage controller 34 includes a solenoid valve 340 and a water pipe 341. The solenoid valve 340 is located inside the water storage chamber 32 and includes two through holes 342. One end of the water pipe 341 is connected to one of its through holes 342, and the other end is connected to the outside of the water storage chamber 32. In this application, the solenoid valve 340 can also be controlled by the sensor-controlled electronic system 41. In other embodiments, a separate control system can be provided. The water storage chamber 32 is connected to the external water environment through the water pipe 341, and the water storage chamber 32 is always filled with water. The water storage chamber 32 is made of 316L stainless steel, with a 3mm thick nano-hydrophobic coating on the inner wall and a volume of 1.2L. A filter screen is provided at the front end of the water storage chamber 32 to prevent large ice particles from entering the system.

[0027] When the solenoid valve 340 is opened, external water flows into or out of the water storage chamber 32 through the water pipe 341 under the action of pressure difference. The water storage chamber 32 is always filled with water to maintain the system pressure balance, thereby increasing or decreasing the water volume in real time to adjust the buoyancy of the device. In practical applications, during the operation in the ice-water transition zone or under-ice water, the sensor control system 41 controls the switching frequency and duration of the solenoid valve 340 according to the sensor feedback signal. For example, when the device sinks, external water is quickly injected to increase the weight, and the water volume in the borehole is finely adjusted to compensate for the buoyancy fluctuation caused by the change in ice density. At the same time, the 316L stainless steel material ensures the structural strength and corrosion resistance at -40℃, and the nano-hydrophobic coating on the inner wall significantly reduces the adhesion of water molecules, prevents freezing and blockage, and reduces water flow resistance, thereby improving the response speed of water volume adjustment. The front-end filter screen effectively intercepts large ice particles, preventing drill debris from entering the system and causing the solenoid valve 340 to jam.

[0028] In this application, a pressure sensor 5 is also installed in the water storage chamber 32. The pressure sensor 5 is connected to the solenoid valve 340. The pressure sensor 5 is used to monitor the water pressure in the water storage chamber 32, so as to control the opening and closing of the solenoid valve 340 according to the water pressure information. By dynamically adjusting the water volume through real-time monitoring of water pressure, buoyancy control with milliliter-level precision in polar drilling can be achieved: the pressure sensor 5 is directly embedded in the water storage chamber 32, continuously collects water pressure data, and is electrically connected to the solenoid valve 340. When the device is operating in the ice-water transition zone or in the water under ice, the sensor and electronic control system 41 automatically analyzes the water pressure change according to the preset threshold. For example, if the external water depth increases during the sinking process, causing the water pressure to rise, the solenoid valve 340 is immediately triggered to open, so that the external water is filtered by the front-end filter screen and injected into the water storage chamber 32 through the water pipe 341, increasing the weight of the device to accelerate the sinking; conversely, when the drilling reaches the target depth and needs to be kept stable, the water pressure fluctuation is captured by the pressure sensor 5. By adjusting the opening and closing frequency and duration of the solenoid valve 340, the water volume is accurately discharged or replenished, and the buoyancy is finely adjusted to counteract the shift of the center of gravity.

[0029] In this application, the air storage controller 35 includes an air compressor pump connected to the air storage chamber 33. The air compressor pump is used to inject air into the air storage chamber 33. In this application, the air compressor pump can also be controlled by the sensor control system 41. In other embodiments, a control system can be set separately. The air compressor pump is directly connected to the air storage chamber 33. When the air compressor pump starts, it injects compressed air into the air storage chamber 33, increasing the air pressure inside the chamber and pushing the piston plate 31 towards the water storage chamber 32, thereby compressing the volume of the water storage chamber 32 and discharging some water to reduce the overall weight of the device. Conversely, stopping the injection or exhaust reduces the air pressure, causing the piston plate 31 to move back and the water storage chamber 32 to absorb water and increase its weight. In practical applications, during the drilling stage in the ice-water transition zone or under-ice water, the sensor and electronic control system 41 adjusts the working parameters of the air compressor pump in real time based on sensor and pressure feedback signals. For example, when the device needs to sink quickly, the system instructs the compressor pump to stop the injection and open the exhaust channel, reducing the air pressure in the air storage chamber 33 so that the water storage chamber 32 can absorb external water and increase negative buoyancy. When encountering strong water flow disturbance or sudden change in the resistance of the drill bit 21, the compressor pump immediately responds by injecting a small amount of air, which works in conjunction with the solenoid valve 340 of the water storage controller 34 to fine-tune the position of the piston plate 31, achieving milliliter-level buoyancy compensation.

[0030] In this application, to facilitate the installation of the propellers 40, a support 7 is provided on the top of the drainage control device 3. The propellers 40 include a vertical main propeller 400 and a horizontal thruster 401. The vertical main propeller 400 is connected to the top corner of the support 7, and the horizontal thruster 401 is connected to both sides of the support 7. The sensing and electronic control system 41 includes a depth sensor 410 and a controller 411. The controller 411 is connected to the depth sensor 410 and is used to control the attitude of the vertical main propeller 400 and the horizontal thruster 401 based on the current depth information.

[0031] When the device drills in the ice-water transition zone or subglacial water, the depth sensor 410 collects the current depth data in real time and transmits it to the controller 411. Based on the preset drilling path and real-time feedback, the controller 411 synchronously adjusts the rotation speed, thrust direction, and tilt angle of the two types of propellers 40 through a vector algorithm. For example, in a strong current environment, if the depth sensor 410 detects that the device has sunk too deep, the controller 411 immediately instructs the vertical main propeller 400 to increase the upward thrust to counteract the negative buoyancy. At the same time, the horizontal thrust propeller 401 generates a reverse horizontal thrust to suppress lateral drift and works in coordination with the solenoid valve 340 in the water storage chamber 32 of the drainage control device 3 and the air compressor pump in the air storage chamber 33. When the center of gravity of the water storage chamber 32 shifts upward due to drainage triggered by the pressure sensor 5, the vertical main propeller 400 finely adjusts the thrust to maintain vertical stability, while the horizontal thrust propeller 401 compensates for the torque generated by the rotation of the drill bit 21, ensuring that the high-strength alloy drill bit 21 always drills vertically along the preset path when penetrating the fragile ice-water transition zone, avoiding deviation or jamming.

[0032] In this application, to facilitate underwater work, a lighting system 8 is also connected to the sealed tank 30. A camera system 9 is also connected inside the gas storage chamber 33, and an observation port 90 is provided at one end of the sealed tank 30, with the lens of the camera system 9 facing the observation port 90. The integrated design of the lighting system 8 and the camera system 9, by connecting a high-brightness LED lighting array to the outside of the sealed tank 30 and embedding a waterproof camera module inside the gas storage chamber 33, combined with the reinforced glass observation port 90 at the end of the sealed tank 30, enables real-time visual monitoring and intelligent decision-making of the drilling environment during operations in subglacial polar waters.
