Description

Technical Field

[0001] This utility model relates to the field of marine drilling technology, and in particular to a stable base for a marine drilling coring device. Background Technology

[0002] Jacket supports are offshore structures widely used in offshore oil and gas development and other fields. They serve as the base for offshore drilling platforms. While existing jacket supports can provide stable support for offshore drilling platforms, floating debris on the seawater can come into contact with the jacket supports due to the fluidity of the seawater. This debris can cause physical damage to the jacket support structure. For example, large floating logs or discarded metal components, when impacted by waves, may scrape or strike the surface of the steel pipes of the jacket support, damaging the anti-corrosion coating and exposing the steel pipes to the seawater environment. This accelerates the corrosion process and reduces the structural strength and durability of the jacket support. Over time, this can lead to localized deformation or even perforation of the steel pipes, threatening the safety and stability of the entire platform. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a stable base for a marine drilling coring device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A stable base for a marine drilling coring device includes a guide frame, a ring body at the guide frame, multiple sets of round rods connected to the ring body, rollers at each of the multiple sets of round rods, and through openings at each of the multiple sets of rollers. The multiple sets of round rods are respectively movably connected to the corresponding through openings, and threaded sleeves are threadedly connected to each of the multiple sets of round rods.

[0006] Preferably, the diameter of each set of threaded sleeves is larger than the diameter of the corresponding orifice.

[0007] Preferably, multiple sets of the circular rods are equidistantly distributed on the ring body.

[0008] Preferably, the outer wall of each of the multiple sets of rollers is wrapped with a rubber ring, and the multiple sets of rubber rings are made of EPDM rubber.

[0009] Preferably, the ring body is connected to multiple sets of rods, and all sets of rods are connected to the guide frame.

[0010] Preferably, none of the multiple sets of threaded sleeves are in contact with the corresponding roller body.

[0011] Preferably, the surfaces of all sets of threaded sleeves are machined with grinding texture.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. Through the coordination of a ring, round rods, rollers, and rubber rings, and by placing rollers at multiple sets of round rods on the ring, these rollers form a ring-shaped interception barrier. When floating objects approach the jacket, the rotation of the rollers at the corresponding round rods, combined with the multiple rollers, creates this ring-shaped barrier, guiding the floating objects and successfully preventing direct collisions and scratches with the jacket. This effectively protects the jacket's anti-corrosion coating and structural integrity. This significantly reduces the risk of corrosion, deformation, and perforation of the jacket's steel pipes caused by floating object impacts, strongly ensuring the long-term safe and stable operation of the offshore drilling platform and reducing high maintenance costs and potential safety accidents caused by structural damage.

[0014] 2. By using the fit between the ring, round rod, roller, through-hole and threaded sleeve, the thread is separated from the round rod, so that the roller can be removed from the round rod. When the roller is damaged, disassembly and replacement are relatively convenient. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1, referring to Figures 1 to 5A stable base for a marine drilling coring device includes a guide frame 1. The guide frame 1 has an annular body 2 made of seawater-resistant stainless steel to effectively reduce seawater adhesion and corrosion. Multiple sets of round rods 3 are connected to the annular body 2. These round rods 3 are made of high-quality carbon steel and undergo rigorous heat treatment to achieve good mechanical strength and wear resistance. Rollers 4 are provided at each of the round rods 3, and each of the rollers 4 has an opening 6. The round rods 3 are movably connected to their corresponding openings 6. The rollers 4 use high-strength alloy steel shafts to ensure they do not deform or break during long-term rotation. Threaded sleeves 7 are threadedly connected to each of the round rods 3. When floating debris approaches the guide frame 1 with the seawater flow, it will first come into contact with the annular barrier formed by the rollers 4. Since the roller 4 can rotate freely on the round rod 3, and the rubber ring 5 on its outer wall can provide good friction and cushioning effect, the floating object will be gradually guided away from the guide frame 1 under the action of the roller 4, thus successfully blocking the direct collision and scraping between the floating object and the guide frame 1.

[0023] In this embodiment, the diameters of multiple sets of threaded sleeves 7 are all larger than the diameters of the corresponding through-holes 6. This design effectively prevents the roller body 4 from detaching from the round rod 3 due to unexpected situations during operation, ensuring the integrity and reliability of the device. Multiple sets of round rods 3 are equidistantly distributed on the ring body 2. The outer walls of multiple sets of roller bodies 4 are all wrapped with rubber rings 5. All sets of rubber rings 5 ​​are made of EPDM rubber, which has excellent weather resistance, ozone resistance, and chemical corrosion resistance. It can maintain good elasticity and physical properties for a long time in seawater environment. Its soft texture can play a buffering role when the roller body 4 comes into contact with floating objects, avoiding excessive compression or damage to the floating objects. At the same time, it can also reduce the impact force of floating objects on the roller body 4, protecting the roller body 4 from damage. Multiple sets of rods 8 are connected to the ring body 2. All sets of rods 8 are connected to the guide frame 1. The rods 8 are made of aluminum alloy, which has the characteristics of light weight and high strength. Multiple sets of rods 8 are connected to the jacket frame 1. This connection method is carefully designed to ensure that the ring 2 can be firmly fixed on the jacket frame 1 and will not shift or loosen when facing wave impacts and other marine external forces, thus ensuring the stability and reliability of the entire floating object interception and guidance device. Multiple sets of threaded sleeves 7 do not contact the corresponding rollers 4, avoiding contact between the rollers 4 placed at the round rod 3 and the threaded sleeves 7, which would affect the operation of the rollers 4. The surfaces of multiple sets of threaded sleeves 7 are all machined with grinding grooves 9. These grinding grooves 9 not only increase the friction of the operator's hands when installing and removing the threaded sleeves 7, making operation easier, but also play a certain role in preventing slippage and loosening, further improving the stability of the threaded connection.

[0024] The working principle of this embodiment is as follows: When floating objects approach the guide frame 1 on the sea surface, they will be intercepted by the annular barrier formed by multiple sets of rollers 4. The rollers 4 can rotate freely at the round rod 3. In this way, the floating objects will be guided by the rollers 4 to change their direction of movement under the transport of seawater, so as to avoid damage to the guide frame 1. When the rollers 4 are damaged, the threaded sleeve 7 is separated from the round rod 3, and the rollers 4 can be removed and replaced at the round rod 3.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
