Description

Technical Field

[0001] This application relates to the field of underwater operation equipment technology, and in particular to an underwater automatic drilling device. Background Technology

[0002] In the development of offshore oil, gas and other resources, offshore platforms are important infrastructure. Underwater drilling can be used to drill holes in seabed rocks or hard soil layers to provide a foundation for anchoring. This ensures that the platform remains stable in complex marine environments, withstands external forces such as wind, waves and currents, prevents displacement or damage due to factors such as currents, and guarantees the safe operation of offshore platforms.

[0003] However, existing underwater drilling mainly relies on divers to manually perform drilling operations. Divers have limited underwater working time and are constrained by factors such as diving depth and oxygen supply. They need to return to the surface periodically to rest and replenish oxygen, which in turn affects the drilling progress. Utility Model Content

[0004] The purpose of this application is to provide an automatic underwater drilling device, which has the advantages of increasing drilling efficiency and solves the problem that existing underwater drilling mainly relies on manual drilling operations by divers. Divers have limited underwater working time and are constrained by factors such as diving depth and oxygen supply. They need to return to the surface regularly to rest and replenish oxygen, which affects the drilling progress.

[0005] This application provides an underwater automatic drilling device with the following technical solution: An underwater automatic drilling device includes an adjusting bracket, a support frame, and a movable plate. Two rotating seats arranged in a mirror image are fixedly connected to one side of the adjusting bracket. A first hydraulic rod is rotatably connected inside each of the two rotating seats. A rotating disk is fixedly connected to one end of each side of the inner wall of the adjusting bracket. A connecting shaft is fixedly connected to one end of each side of the support frame. A second hydraulic rod is fixedly connected to one side of the inner wall of the support frame. A movable frame is fixedly connected to the output end of the second hydraulic rod. Two positioning brackets arranged in a mirror image are fixedly connected to one side of the movable frame. Two supporting legs arranged in a mirror image are fixedly connected to the ends of the two positioning brackets away from the movable frame. Two first hydraulic motors arranged in a mirror image are fixedly connected to the end of the movable frame away from the positioning brackets. Rotating plates are fixedly connected to both sides of the inner wall of the movable frame. Threaded rods are rotatably arranged on one side of each of the two rotating plates. Two threaded holes arranged in a mirror image are opened inside the movable plate.

[0006] By adopting the above technical solution, through the setting of the adjusting bracket, the first hydraulic rod, and the rotating disk, the first hydraulic rod is connected to the adjusting bracket via a connecting shaft. Simultaneously, the rotating disk on the inner wall of the adjusting bracket rotates in coordination with the support frame, allowing the support frame to rotate around the rotating disk. By controlling the extension and retraction of the first hydraulic rod, the angle of the support frame and the drilling device can be adjusted to adapt to underwater operations at different inclination angles, meeting diverse underwater drilling needs and improving the equipment's applicability. The second hydraulic rod drives the moving frame to slide within the support frame, causing the positioning bracket to contact the working surface. The support legs on the positioning bracket contact the working surface during drilling, providing additional support points for the entire drilling device, reducing device sway and displacement, and enhancing the equipment's underwater stability. The first hydraulic motor drives the threaded rod to rotate, realizing control of the moving plate, allowing precise adjustment of drilling depth and speed according to actual needs. This device, through the setting of the adjusting bracket, the first hydraulic rod, the rotating disk, the connecting shaft, and the support frame, can adapt to underwater working surfaces at different inclination angles, meeting diverse underwater drilling needs and improving the equipment's automation and applicability.

[0007] Preferably, a second hydraulic motor is fixedly connected to one side of the movable plate, and a coupling is fixedly connected to one end of the output end of the second hydraulic motor that passes through the movable plate. A drill bit is fixedly connected inside the coupling by bolts.

[0008] By adopting the above technical solution, the second hydraulic motor provides rotational power to the drill bit. The hydraulic motor has the characteristics of large output torque and strong power. When facing hard geological conditions such as seabed rocks and hard soil layers, it can generate sufficient rotational force to enable the drill bit to drill smoothly, effectively improving drilling efficiency and shortening operation time. The drill bit is fixedly connected inside the coupling by bolts, making the installation and removal of the drill bit relatively convenient. When the drill bit is worn or the drill bit type needs to be changed according to different geological conditions, the old drill bit can be removed simply by unscrewing the bolts, and then the new drill bit can be installed and the bolts tightened. The operation is simple and quick, shortening equipment maintenance and preparation time and improving operation efficiency.

[0009] Preferably, the output ends of both first hydraulic motors are fixedly connected to the threaded rods through one end of the movable frame, and both threaded rods are threaded inside the threaded holes.

[0010] By adopting the above technical solution, the rotation speed and direction of the threaded rod can be controlled by driving the threaded rod with the first hydraulic motor. Through the threaded transmission between the threaded rod and the threaded hole, the movement distance of the moving plate can be controlled, thereby precisely adjusting the drilling depth. By adjusting the rotation speed of the first hydraulic motor, the rotation speed of the threaded rod also changes accordingly. Thus, the feed speed of the drill bit can be adjusted according to different geological conditions and drilling requirements. In soft soil strata, the feed speed can be appropriately increased to improve drilling efficiency, while in hard rock strata, the feed speed can be reduced to ensure that the drill bit can drill smoothly and avoid damage to the drill bit due to excessive speed.

[0011] Preferably, two mirror-distributed limiting plates are fixedly connected to both sides of the movable plate, and two mirror-distributed limiting grooves are opened on both sides of the inner wall of the movable frame, with all four limiting plates slidably disposed inside the limiting grooves.

[0012] By adopting the above technical solution, the limiting plate slides in the limiting groove, providing a stable guide for the movement of the moving plate, so that it can only move along the straight trajectory set by the limiting groove, preventing interference from factors such as complex underwater environment or water flow impact on the drilling equipment, thereby increasing the accuracy of drilling position and depth.

[0013] Preferably, the movable frame is slidably disposed inside the support frame.

[0014] By adopting the above technical solution, the mobile frame slides within the support frame, enabling the drilling device to move horizontally. In scenarios such as seabed geological exploration or offshore platform foundation construction, the drilling requirements at different locations vary. By controlling the sliding of the mobile frame, the drill bit can be easily moved to the designated drilling position, improving the flexibility and efficiency of the operation.

[0015] Preferably, the support frame has four sliding grooves arranged in a mirror image at both the upper and lower ends, and the movable frame has four limiting strips arranged in a mirror image fixedly connected to both the upper and lower sides, with the multiple limiting strips slidably disposed inside the sliding grooves.

[0016] By adopting the above technical solution, the slide provides a movement track for the limit bar, so that the sliding of the mobile frame within the support frame can only be carried out in the direction set by the slide, limiting the lateral displacement of the mobile frame and ensuring that it always slides smoothly along a straight line.

[0017] Preferably, the upper side of the adjustment bracket has two mounting holes arranged in a mirror image.

[0018] By adopting the above technical solution, the two mirror-distributed mounting holes provide an installation foundation for attaching the device to power units such as ships. During the installation process, the operator can align the mounting holes on the adjusting bracket with the preset installation positions on the ship and quickly complete the installation using bolts, nuts and other connecting parts, which shortens the installation time and improves the installation efficiency.

[0019] Preferably, the ends of the two first hydraulic rods furthest from the rotating seat are rotatably sleeved on the outer wall of the connecting shaft, and the ends of the two rotating disks furthest from the adjusting bracket are rotatably connected to the support frame.

[0020] By adopting the above technical solution, the end of the first hydraulic rod away from the rotating seat is rotatably sleeved on the outer wall of the connecting shaft, while the end of the rotating disk away from the adjusting bracket is rotatably connected to the support frame. This allows the support frame to rotate at multiple angles via the rotating disk, enabling the device to flexibly adjust the angle and position of the support frame according to different terrains and drilling requirements through the extension and retraction of the hydraulic rod and the rotation of the rotating disk, thereby ensuring that the drill bit can accurately reach the target drilling position.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] This underwater automatic drilling equipment, through the arrangement of an adjusting bracket, a first hydraulic rod, a rotating disk, and a connecting shaft, allows the rotating seat on the adjusting bracket to be rotatably connected to the first hydraulic rod. The other end of the first hydraulic rod is rotatably sleeved on the outer wall of the connecting shaft of the supporting frame. The rotating disk on the inner wall of the adjusting bracket is rotatably engaged with the supporting frame. By controlling the extension and retraction of the first hydraulic rod, the supporting frame can rotate around the rotating disk at multiple angles to adapt to underwater working surfaces with different inclination angles, meeting diverse drilling needs. During drilling, a second hydraulic rod drives a moving frame to slide within the supporting frame, and the supporting legs of the positioning bracket contact the working surface to provide additional support. External support points reduce device sway and displacement. The sliding groove and limit strip work together to limit the lateral displacement of the moving frame, ensuring smooth sliding and enhancing the underwater stability of the equipment. The first hydraulic motor drives the threaded rod to rotate, and the threaded rod and the threaded hole of the moving plate drive the threaded transmission. Combined with the guiding effect of the limit plate and the limit groove, the moving distance of the moving plate can be controlled, thereby adjusting the drilling depth. At the same time, adjusting the speed of the first hydraulic motor can flexibly adjust the drill bit feed speed to adapt to different geological conditions. The mounting hole design makes it easy for the device to be quickly attached to power units such as ships, realizing the automated drilling operation of the device. Attached Figure Description

By controlling the extension and retraction of the first hydraulic rod 4, the angle of the support frame 2 and the drilling device can be adjusted to adapt to underwater operations at different inclination angles, meeting diverse underwater drilling needs and improving the applicability of the equipment. Rotating disks 5 are fixedly connected to one end of each side of the inner wall of the adjusting bracket 1. The rotating disks 5 on the inner wall of the adjusting bracket 1 rotatably cooperate with the support frame 2, allowing the support frame 2 to rotate around the rotating disks 5. Connecting shafts 6 are fixedly connected to one end of each side of the support frame 2. The first hydraulic rod 4 is connected to the adjusting bracket 1 through the connecting shafts 6. A second hydraulic rod 7 is fixedly connected to one side of the inner wall of the support frame 2. A movable frame 8 is fixedly connected to the output end of the second hydraulic rod 7. The movable frame 8 has one side... Two positioning brackets 9 are fixedly connected in a mirror-shaped arrangement. The second hydraulic rod 7 drives the moving frame 8 to slide within the support frame 2, causing the positioning brackets 9 to contact the working surface. Two support legs 10 are fixedly connected to the ends of the two positioning brackets 9 away from the moving frame 8, which are arranged in a mirror-shaped arrangement. The support legs 10 on the positioning brackets 9 contact the working surface during drilling, providing additional support points for the entire drilling device, reducing the shaking and displacement of the device, and enhancing the stability of the equipment underwater. Two first hydraulic motors 11 are fixedly connected to the ends of the moving frame 8 away from the positioning brackets 9, which are arranged in a mirror-shaped arrangement. The first hydraulic motors 11 drive the threaded rod 13 to rotate, realizing the control of the moving plate 14, so that the drilling depth and speed can be precisely adjusted according to actual needs. Rotating plates 12 are fixedly connected to both sides of the inner wall of the moving frame 8, and threaded rods 13 are rotatably arranged on one side of each of the two rotating plates 12.

[0032] Reference Figure 1 , Figure 3 and Figure 4 The movable plate 14 has two mirror-shaped threaded holes 15 inside. The movable plate 14 is used to support the drilling device. A second hydraulic motor 16 is fixedly connected to one side of the movable plate 14. The second hydraulic motor 16 provides rotational power to the drill bit 18. The hydraulic motor has the characteristics of large output torque and strong power. When facing hard geological conditions such as seabed rocks and hard soil layers, it can generate sufficient rotational force to enable the drill bit 18 to drill smoothly, effectively improving drilling efficiency and shortening operation time. The output end of the second hydraulic motor 16 is fixedly connected to a coupling 17 through one end of the movable plate 14. The drill bit 18 is fixedly connected to the inside of the coupling 17 by bolts. The installation and removal of the drill bit 18 is relatively convenient. When the drill bit 18 is worn or needs to be replaced according to different geological conditions, the old drill bit 18 can be removed by simply unscrewing the bolts, and then the new drill bit 18 can be installed and the bolts tightened. The operation is simple and quick, shortening equipment maintenance and preparation time and improving operation efficiency.

[0033] Example 2: An underwater automatic drilling device, referring to Figure 1 , Figure 3 and Figure 5The output ends of both first hydraulic motors 11 are fixedly connected to threaded rods 13 at one end of the movable frame 8. Both threaded rods 13 are threaded inside threaded holes 15. By driving the threaded rods 13 through the first hydraulic motors 11, the rotation speed and direction of the threaded rods 13 can be controlled. Through the threaded transmission between the threaded rods 13 and the threaded holes 15, the moving distance of the movable plate 14 can be controlled, thereby precisely adjusting the drilling depth. By adjusting the rotation speed of the first hydraulic motors 11, the rotation speed of the threaded rods 13 also changes accordingly. Thus, the feed speed of the drill bit 18 can be adjusted according to different geological conditions and drilling requirements. In soft soil strata, the feed speed can be appropriately increased to improve drilling efficiency, while in hard rock strata, the feed speed can be decreased. To ensure the drill bit 18 can drill smoothly and avoid damage due to excessive speed, two mirror-shaped limiting plates 19 are fixedly connected to both sides of the moving plate 14. Two mirror-shaped limiting grooves 20 are opened on both sides of the inner wall of the moving frame 8. All four limiting plates 19 are slidably disposed within the limiting grooves 20, providing stable guidance for the movement of the moving plate 14. This ensures that it can only move along the straight trajectory set by the limiting grooves 20, preventing interference from complex underwater environments or water flow impacts on the drilling equipment, thereby increasing the accuracy of drilling position and depth. The moving frame 8 is slidably disposed inside the support frame 2, allowing the drilling device to... The horizontal movement of the mobile frame 8 allows for easy movement of the drill bit 18 to the designated drilling position, improving operational flexibility and efficiency. The support frame 2 has four mirror-distributed grooves 21 at both its upper and lower ends. Four mirror-distributed limiting strips 22 are fixedly connected to the upper and lower sides of the mobile frame 8. These limiting strips 22 are slidably positioned within the grooves 21, providing a track for the limiting strips 22. This ensures that the mobile frame 8 can only slide along the direction set by the grooves 21, limiting lateral displacement and guaranteeing smooth, straight-line sliding. Adjusting the support frame... Two mirror-shaped mounting holes 23 are provided on one side of the upper end of the frame 1. These two mirror-shaped mounting holes 23 provide a mounting base for externally mounting the device onto a ship or other power unit. During installation, the operator can align the mounting holes 23 on the adjusting bracket 1 with the pre-set mounting positions on the ship and quickly complete the installation using bolts, nuts, and other connecting parts, shortening the installation time and improving installation efficiency. The ends of the two first hydraulic rods 4 furthest from the rotating seat 3 are rotatably sleeved on the outer wall of the connecting shaft 6. The ends of the two rotating disks 5 furthest from the adjusting bracket 1 are rotatably connected to the support frame 2.This allows the support frame 2 to rotate at multiple angles via the rotating disk 5. The device can flexibly adjust the angle and position of the support frame 2 according to different terrains and drilling requirements through the extension and retraction of the hydraulic rods and the rotation of the rotating disk 5, thereby ensuring that the drill bit 18 accurately reaches the target drilling position.

[0034] The implementation principle of this application embodiment is as follows:

[0035] First, the equipment is externally mounted to a ship or other power unit via the mounting holes 23 on the bracket 1, allowing it to be moved to the work site. Using the extension and retraction of the first hydraulic rod 4, in conjunction with the rotational connection between the rotating disk 5 and the support frame 2, the angles of the support frame 2 and the drilling device can be adjusted to accommodate underwater work surfaces with different inclination angles. Subsequently, the second hydraulic rod 7 drives the moving frame 8 to slide along the slide groove 21 within the support frame 2, causing the support legs 10 on the positioning bracket 9 to contact the work surface, providing stable support for the equipment and reducing swaying during underwater operations. During drilling, the first hydraulic rod... The machine 11 drives the threaded rod 13 to rotate, and through the cooperation with the threaded hole 15 of the moving plate 14, controls the lifting and lowering of the moving plate 14, thereby adjusting the drilling depth and the feed speed of the drill bit 18. At the same time, the sliding cooperation between the limiting plate 19 and the limiting groove 20 and the limiting strip 22 and the sliding groove 21 ensures that the moving plate 14 and the moving frame 8 move smoothly along a straight line, avoiding deviation caused by the complex underwater environment. The second hydraulic motor 16 drives the drill bit 18 to rotate, and the coupling 17 facilitates quick and easy disassembly and assembly of the drill bit 18 to cope with different geological conditions, realizing the automation of angle adjustment and automatic drilling in underwater drilling operations.
