Description

Technical Field

[0001] The invention relates to an underwater oilfield emergency repair basic platform, which is mainly used for being quickly arranged on the seabed and capable of placing repair equipment when emergency situations occur in underwater oilfields and repairs are needed. Background Art

[0002] my country has vigorously developed its offshore oil and gas industry in recent years, and has successfully developed a number of underwater production system equipment. In the next few years, my country is expected to achieve complete domestic substitution of deepwater underwater production systems.

[0003] Underwater oil and gas extraction is difficult to implement. Once a fault occurs during the extraction process, it may cause production to be suspended, resulting in huge losses to the oil company. In serious cases, it may cause oil and gas leakage, causing irreparable damage to construction personnel, property and the ecological environment.

[0004] Therefore, when underwater equipment is suspected of or has failed, quickly deploying underwater maintenance equipment to the seabed in the oil field area is an effective way to reduce losses.

[0005] If the repair equipment is placed directly on the seabed, it will sink into it, making it impossible to carry out repairs. Therefore, it is necessary to arrange the basic structure on the seabed in advance to provide space for the repair equipment.

[0006] It is very necessary to study an underwater emergency repair basic platform that can be quickly deployed and easily operated. Summary of the invention

[0007] In order to solve the problem of rapid deployment of underwater repair equipment, the present invention proposes an underwater oilfield emergency repair basic platform, which is foldable, occupies less ship space, has low requirements on ship size, and its seabed deployment process is simple to operate, has low operating costs, and meets the requirements of rapid deployment.

[0008] The technical solution adopted by the present invention to solve the technical problem is as follows: the device of the present invention comprises a central anti-sinking plate, a side plate, a side plate, a connecting rod, a slider, and a ring lock. The central anti-sinking plate and the side plate are hingedly connected, the side plate and the side plate are hingedly connected, and the side plate, the connecting rod, and the slider are hingedly connected in sequence. When the device of the present invention is stored or hoisted, the side plate and the side plate can be folded, saving space, reducing the requirements for the ship and reducing the difficulty of operation; during emergency repair, it can be quickly unfolded, which is conducive to the rapid arrangement of emergency repair equipment.

[0009] The beneficial effects of the present invention are as follows: the device of the present invention occupies a small space, is simple to hoist, and is convenient for rapid deployment. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Depend on Figure 1 , 2 As shown, the main body of the central anti-sinking plate 1 is a central plate 1-1, which has a plurality of drainage holes. The central anti-sinking plate 1 is surrounded by a central skirt plate 1-2, and a reinforcing skirt plate 1-8 is provided at the bottom. The central plate 1-1 is provided with side plate shaft arms 1-3 and connecting rod non-return ribs 1-4, each group of which is composed of a pair of steel plates. Each group of side plate shaft arms 1-3 has a shaft hole. During assembly, the shaft hole is inserted into the side plate shaft 1-6. The figure shows the state of the side plate shaft 1-6 after installation. The upper end of the side plate shaft arm 1-3 extends to the outside of the central plate 1-1. The gap formed by the side plate shaft arm 1-3 and the connecting rod non-return rib 1-4 is the connecting rod non-return groove 1-5, which is an arc-shaped structure. The slide rail 1-7 is installed on the central plate 1-1 near the connecting rod non-return rib 1-4.

[0019] Depend on Figure 3 , 4As shown, the main body of the side panel 2, the main side panel 2-1, is a triangular structure, on which a number of drainage holes are arranged. Three sets of side panel connecting rod shafts 2-2 and central anti-sinking plate shaft arms 2-3 are arranged on one side of the short side of the side panel main panel 2-1. The side panel connecting rod shaft 2-2 includes an axis hole and a rotating shaft, and the figure shows the state after the rotating shaft is installed in the axis hole. The side panel main panel 2-1 is arranged on both long sides of the side panel main panel 2-1. A side panel skirt 2-5 is arranged on one side of the side panel hinge shaft 2-4, which is a rectangular steel plate with a hanging hole 2-6 on it.

[0020] Depend on Figure 5 As shown, the main side plate 3-1 of the side plate 3 is a fan-shaped structure with two unequal straight sides, on which drainage holes are arranged. A straight side of the main side plate 3-1 has a side plate hinge shaft 3-2, and the other straight side and the arc side intersection position has a side plate ring lock hole 3-3.

[0021] Depend on Figure 6 As shown, there are a pair of connecting rod side plate shaft holes 4-2 and a pair of slider shaft holes 4-3 at both ends of the connecting rod 4, and a slider groove 4-4 is provided on one side of the slider shaft hole 4-3, which is an extension of the middle groove of the connecting rod 4. There is a through groove in the middle of the connecting rod 4, and a check rod 4-1 is provided on the side close to the slider shaft hole 4-3.

[0022] Depend on Figure 7 As shown, the slider 5 is composed of a slider boss 5-1 as a base, and a slider shaft 5-2 is disposed thereon. The slider shaft 5-2 is an independent component and is inserted into the shaft hole on the slider 5 during installation. Figure 7 This is the post-installation state.

[0023] Depend on Figure 1 , 2 , 3, 4, 5, 6, 7, 8, 9, and 10.

[0024] When assembling the present invention, firstly put the central anti-sinking plate 1 in place, insert the slider boss 5-1 of the slider 5 into the slide rail 1-7, and the side of the slider boss 5-1 extending out of the main body should face away from the connecting rod check rib 1-4. Then install the connecting rod 4, make the slider shaft hole 4-3 correspond to the shaft hole of the slider shaft 5-2, and then install the slider shaft 5-2, so that the connection mode between the connecting rod 4 and the slider 5 is hinged.

[0025] After completing the above steps, hoist the side panel 2, hoist the central anti-sinking plate shaft arm 2-3 until its shaft hole corresponds to the shaft hole of the side panel shaft arm 1-3, and install the side panel shaft 1-6 so that the side panel 2 is hingedly connected to the central anti-sinking plate 1. Then, the shaft hole of the side panel connecting rod shaft 2-2 corresponds to the connecting rod side panel shaft hole 4-2, and install the rotating shaft so that the connecting rod 4 is hingedly connected to the side panel 2. At this time, with the side panel shaft 1-6 as the axis, when the side panel 2 rotates relative to the central anti-sinking plate 1, the connecting rod 4 drives the slider 5 to slide in the slide rail 1-7. When the side panel 2 rotates outward relative to the central anti-sinking plate 1, the check rod 4-1 will enter the connecting rod check groove 1-5, and when the side panel main board 2-1 and the central panel 1-1 are coplanar, the check rod 4-1 slides into the bottom of the connecting rod check groove 1-5.

[0026] After completing the above steps, the side panel 3 is hoisted, the side panel hinge shaft 3-2 is hingedly connected to the side panel hinge shaft 2-4, and the adjacent side panels 3 are connected by installing the ring lock 6 in the side panel ring lock hole 3-3, and the ring lock 6 is welded by a semicircular iron ring.

[0027] Figure 8 This is the appearance of the device after assembly, and is also the placement state of the device when not in use. When the device is stored, the four hanging holes 2-6 should be connected and fixed to each other using ropes to prevent the folded side panels 2 and side panels 3 from accidentally unfolding.

[0028] During emergency deployment, the device of the present invention can be lifted up by connecting the ropes of the lifting holes 2-6. Figure 8 When the device of the present invention is deployed, it is lifted by the rope connected to the lifting hole 2-6 and lowered to the seabed. After the central skirt plate 1-2 touches the seabed, the lifting hole 2-6 is pulled outward by the rope to unfold the side plate 2 and the side plate 3 until the side plate main board 2-1 and the side plate main board 3-1 are coplanar with the central plate 1-1. At this time, the non-return rod 4-1 slides into the connecting rod non-return groove 1-5.

[0029] During the arrangement of underwater emergency repair equipment, the equipment should be placed on the central plate 1-1 first, and the central skirt plate 1-2 and the reinforced skirt plate 1-8 should be pressed into the seabed by the weight of the equipment. During the pressing process of the central plate 1-1, the seawater under the central plate 1-1 is discharged through its drainage holes.

[0030] The order of placing the underwater heavy-duty emergency repair equipment is the central anti-sinking plate 1, the side plate 2, and the side plate 3. When the equipment is placed on the side plate 2, the side plate skirt 2-5 will be pressed into the seabed. The drainage holes on the central plate 1-1, the side plate main board 2-1, and the side plate main board 3-1 all play a drainage role when the central plate 1-1, the side plate main board 2-1, and the side plate main board 3-1 are pressed down to the seabed, so that the central plate 1-1, the side plate main board 2-1, and the side plate main board 3-1 are closely attached to the seabed. When the device of the present invention is urgently arranged, the rope connected to the lifting hole 2-6 is not disconnected.

[0031] Since the upper end of the side plate shaft arm 1-3 extends to the outside of the central plate 1-1, and the non-return rod 4-1 is located at the bottom of the connecting rod non-return groove 1-5, if the side plate 2 is subjected to force that does not just cause the side plate 2 to rotate relative to the central anti-sinking plate 1 about the side plate shaft 1-6, the side plate 2 will maintain its current position.

[0032] After the emergency repair is completed and the emergency repair equipment is recovered, high-pressure water is injected into the anti-sinking plate 1, the side plate 2, and the side plate 3 to wash away the sea sand, so that the anti-sinking plate 1, the side plate 2, and the side plate 3 are separated from the seabed, and then the rope connected to the lifting hole 2-6 is lifted, and the side plate skirt 2-5 is pulled out from the seabed, and the side plate 2 and the side plate 3 are restored to the folded state. Finally, the rope connected to the lifting hole 2-6 is lifted, and the central skirt 1-2 and the reinforced skirt 1-8 are pulled out of the seabed, and the device of the present invention is recovered to the ship for use in the next emergency repair.
