Description

Technical Field

[0001] This utility model relates to the technical field of water-proof guide pipe support devices, specifically a drilling water-proof guide pipe support device for marine engineering. Background Technology

[0002] In offshore oil and gas drilling, the riser and its support system are crucial subsea infrastructure. The riser is essentially a large-diameter, high-strength steel pipe connecting the offshore drilling platform (or drilling vessel) to the subsea wellhead. Its core functions are to isolate seawater, provide a guiding channel for drilling tools (drill string, drill bit, casing, etc.) to enter the wellhead, and provide a closed-loop circulation loop for drilling fluid to return from the bottom of the well to the platform, maintaining well control safety. The support system ensures the riser remains vertical, stable, and accurately positioned underwater. It typically includes a guide frame on the subsea, a wellhead base plate or tension ring system, and a tensioner system connected to the top of the riser (used on floating platforms). This support structure works together to withstand the riser's own weight, internal fluid pressure, external seawater pressure, ocean current impact, wave loads, and potential ship movement, preventing excessive bending or failure of the riser. It is crucial for ensuring the safe and efficient conduct of drilling operations.

[0003] Because the ocean is usually very deep, multiple riser pipes are usually required to be connected. This can easily lead to unstable connection points, which are susceptible to shaking due to water flow. A large number of support structures are usually needed to provide stable support for the pipes. However, due to the large number of supports, the connection is difficult and unstable, and the pipes are also not easy to recover. Utility Model Content

[0004] The purpose of this invention is to provide a drilling riser support device for marine engineering to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a drilling riser support device for marine engineering, comprising a base and a stabilizing seat, wherein a stabilizing and easy-to-disassemble mechanism is provided on the inner side of the base and a stabilizing support mechanism is provided on the upper side of the stabilizing seat;

[0006] The stabilizing and disassembling mechanism includes a centering seat, which is fixedly connected to the middle side of the base. Multiple winding platforms are arranged on the upper side of the base, and these platforms are located on both sides of the stabilizing seat. A pulley is rotatably connected to the inner side of each adjacent winding platform. Multiple positioning grooves are evenly distributed inside the centering seat. Connecting seats are fixedly connected to the upper surface of the stabilizing seat. Threaded sleeves are threadedly connected to the outer walls of each connecting seat. Cables are fixedly connected to the upper ends of each threaded sleeve, and these cables are fixedly connected to the inner sides of adjacent winding platforms. The cables abut against the outer walls of adjacent pulleys. Multiple threaded cylinders are threadedly connected to the upper end of the stabilizing seat, and these threaded cylinders are slidably connected to the inner walls of the positioning grooves.

[0007] Preferably, the upper outer wall of the threaded cylinder is provided with a threaded structure, and the lower inner wall of the threaded cylinder is provided with a threaded structure.

[0008] Preferably, a high-power drive motor or engine is provided on one side of the winding table.

[0009] Preferably, the outer diameter of the threaded cylinder is the same as the inner diameter of the threaded cylinder.

[0010] Preferably, the stabilizing support mechanism includes a sliding sleeve, the outer wall of which is slidably connected to a plurality of threaded cylinders, and a plurality of sliding cylinders are fixedly connected to the lower surface of the sliding sleeve. The sliding cylinders are evenly distributed on the lower side of the sliding sleeve. A plurality of positioning rods are fixedly connected to both the stabilizing base and the upper surface of the sliding sleeve. The positioning rods are slidably connected to adjacent sliding cylinders. A turntable is rotatably connected inside the sliding sleeve. A plurality of sliding rods are slidably connected inside the turntable. A sliding platform is fixedly connected to the upper end of each sliding rod.

[0013] Compared with the prior art, this utility model provides a drilling riser support device for marine engineering, which has the following advantages:

[0014] The stabilizing and disassembling mechanism is used for the stable assembly and disassembly of the water-tight pipe support. This mechanism provides installation centering for the stabilizing seat through the centering seat, and the use of cables allows the threaded cylinders to be continuously stacked, thereby improving the stability of the connection and reducing the connection difficulty. It makes it easier for the stabilizing seat to keep concentric with the centering seat with less error. Moreover, when disassembly is required, the stabilizing seat can be raised and removed one by one, avoiding the problem of the stabilizing seat not being able to be recycled, reducing the complexity of the structure and improving stability.

[0015] The stabilizing support mechanism is used to clamp and support the catheter. This mechanism uses a multi-stage rigidly connected threaded cylinder as a guide rail for limiting, so that the sliding sleeve can drive the sliding cylinder to complete the docking with the centering rod. This avoids the problem of unstable connection caused by the lack of rigid connection in existing devices. At the same time, the mechanism uses multiple clamping plates to expand and contract freely, so that the clamping plates can form a stable clamp with the outer wall of the catheter, and the rigid connection of the threaded cylinder can act on the catheter to prevent it from shaking.

[0028] Furthermore, a high-power drive motor or engine is installed on one side of the winding table 302.

[0029] Furthermore, the outer diameter of the threaded cylinder 308 is the same as the inner diameter of the threaded cylinder 308. Example

[0030] This mechanism is used to create a multi-point, uniform clamping effect on the outer wall of the catheter, thus improving the overall stability of the catheter. Please refer to [link / reference needed]. Figures 1-5 Furthermore, in conjunction with Embodiment 1, the stabilizing support mechanism 4 includes a sliding sleeve 401. The outer wall of the sliding sleeve 401 is slidably connected to multiple threaded cylinders 308. Multiple sliding cylinders 402 are fixedly connected to the lower surface of the sliding sleeve 401, and the sliding cylinders 402 are evenly distributed on the lower side of the sliding sleeve 401. Multiple positioning rods 403 are fixedly connected to both the stabilizing seat 2 and the upper surface of the sliding sleeve 401. Each positioning rod 403 is slidably connected to an adjacent sliding cylinder 402. A turntable 404 is rotatably connected inside the sliding sleeve 401. Multiple sliding rods 405 are slidably connected inside the turntable 404, and each sliding rod 405 has a fixedly connected upper end to a sliding... The platform 406 and the slide 406 both pass through the slide sleeve 401 and are slidably connected to the inner wall of the slide sleeve 401.

[0031] Furthermore, the turntable 404 has multiple slots inside, which are evenly distributed inside the turntable 404.

[0032] Furthermore, the inner walls of the 407 plywood are all designed with a rounded structure.

[0033] In actual operation, when this device is used, the user connects the threaded sleeve 306 to the connecting seat 305, and then the user fixes the cable 307 to the threaded sleeve 306. At this time, the user can start the power unit to provide power to the winding table 302, which facilitates the movement of the stable seat 2. At this time, the stable seat 2 is slidably connected to the inner wall of the centering seat 301. The user can thread the threaded cylinder 308 to the stable seat 2 and drive the winding table 302 to release the cable 307 to make the stable seat 2 descend. As the threaded cylinders 308 are continuously stacked and the stable seat 2 continues to sink, the stable seat 2 is inserted into the seabed by its own weight after reaching the seabed. The user can further connect the threaded cylinder 308 to the base 1 through the threaded structure. At this time, the user can fit the sliding sleeve 401 against the surface of the threaded cylinder 308. With a rigid connection, the user can slide the sliding sleeve 401 down to the upper side of the stabilizing seat 2. After the sliding sleeve 401 is connected to the positioning rod 403 through the sliding cylinder 402, the user can repeat this operation until the clamping plates 407 are evenly distributed on the outside of the conduit. Then, the user starts all the self-locking motors 410. The self-locking motors 410 drive the gears 411 to make the turntable 404 rotate. When the turntable 404 rotates, it pushes the sliding rod 405 to move through multiple slots. The sliding rod 405 drives multiple clamping plates 407 to approach each other, so that the outer wall of the conduit is clamped, thereby providing stable support for the conduit. When the user needs to disassemble, he / she needs to close the clamping state of the clamping plates 407 and start the power device. Due to the buoyancy of seawater, the stabilizing seat 2 is lifted by using the starting device. Then, the device is removed step by step to complete the recovery of all components.
