Technical Field
[0001] This application relates to the field of connecting clamp technology, and in particular to a corrosion-resistant connecting clamp for deep-sea oil extraction. Background Technology
[0002] With the dwindling onshore oil resources and the ever-increasing global energy demand, the development of seabed oil resources has become increasingly important. Deep-sea oil pipelines are vital channels connecting seabed oil and gas fields with onshore or offshore processing facilities.
[0003] The splicing of existing deep-sea oil extraction pipelines requires the use of appropriate connecting clamps for fixation. These clamps are typically connected to the pipelines via precise threads.
[0004] The existing technical solutions mentioned above have the following drawbacks: the connecting clamps are easily corroded after long-term use, which can lead to loosening of the pipe connection, resulting in leakage or even disconnection of the pipe connection. Utility Model Content
[0005] This application provides a corrosion-resistant connecting clamp for deep-sea oil extraction to increase the stability of oil pipeline connections.
[0006] The above-mentioned technical objective of this application is achieved through the following technical solution:
[0007] A corrosion-resistant connecting clamp for deep-sea oil extraction includes a mounting plate with fixing holes and mounting blocks. At least two pipe clamps are fixed to the mounting blocks, each including a connecting block fixed to the mounting block. A fixing clamp is integrally formed on the connecting block, and a movable clamp is hinged to one end of the fixing clamp, allowing the movable clamp to close with the fixing clamp to form a ring. A fixing block is integrally formed at one end of the movable clamp. A strip groove is formed on the fixing block, and a fastening bolt is rotatably connected to the connecting block. One end of the fastening bolt is located within the strip groove, and a nut is threaded to one end of the fastening bolt. The nut fits against the outer wall of the fixing block. The entire connecting clamp is coated with a corrosion-resistant coating.
[0008] By adopting the above technical solution, bolts or other methods are used to pass through the fixing holes and fix the mounting plate to the external structure. The two pipe clamps are opened and the pipes to be connected are fixed in the two pipe clamps respectively. The two pipes are connected to each other and fixed by the two pipe clamps. This makes it easy for the staff to connect the two pipes to each other. Fixing the mounting plate to the external structure through the fixing holes can increase the stability of the pipe connection and increase the stability of the connecting clamp for fixing the pipe connection. The multiple spaced fixing holes make it easy for the staff to select the installation method according to the site environment and to fix the connecting clamp to the external structure.
[0009] Optionally, both the fixed hoop and the movable hoop are provided with countersunk holes. An adjusting bolt is provided in the countersunk hole. The head of the adjusting bolt passes through the countersunk hole and is threadedly connected to an adjusting clip. The two adjusting clips are respectively fitted to the inner walls of the fixed hoop and the movable hoop and can be closed to form a ring.
[0010] By adopting the above technical solution, the inner diameter of the pipe clamp can be reduced, the applicable range of the connecting clamp can be increased, and it is easier for workers to use the pipe clamp to fix pipes with smaller diameters.
[0011] Optionally, a groove is provided on one side of the fixing block to prevent the nut from coming off.
[0012] By adopting the above technical solution, the nut can be embedded in the anti-loosening groove, which can increase the stability of the nut on the fixing block, and at the same time increase the stability of the pipe clamp for fixing the pipe.
[0013] Optionally, a sealing block is embedded in the strip groove.
[0014] By adopting the above technical solution, the sealing block can protect the peripheral wall of the fastening bolt and the internal thread of the nut, reducing the risk of loosening of the connection caused by corrosion.
[0015] Optionally, a protective cap may be machined on one side of the nut.
[0016] By adopting the above technical solution, the connection between the nut and the fastening bolt can be protected, reducing the risk of loosening caused by corrosion.
[0017] Optionally, a washer is bonded to one side of the nut.
[0018] By adopting the above technical solution, the washer can reduce the risk of the nut loosening due to pipeline vibration, while protecting the connection between the nut and the fastening bolt and reducing the risk of loosening caused by corrosion.
[0019] Optionally, a sealing plug is embedded in the countersunk hole.
[0020] By adopting the above technical solutions, corrosion caused by seawater and microorganisms entering the gaps between the adjusting bolts and the fixed or movable hoops can be reduced, ensuring the safety and stability of the connecting hoops during operation.
[0021] Optionally, both the fixed hoop and the movable hoop are integrally formed with reinforcing ribs.
[0022] By adopting the above technical solutions, the overall structural strength of the pipe clamp can be increased, ensuring that the ferrule can firmly clamp the pipe.
[0023] In summary, this application has the following technical effects:
[0024] 1. By setting up mounting plates, mounting blocks, and pipe clamps, it is easy for workers to connect two pipes to each other. The mounting plates are fixed to the external structure through the fixing holes, which can increase the stability of the pipe connection and the stability of the connecting clamp for fixing the pipe connection. The multiple spaced fixing holes allow workers to choose the installation method according to the site environment and make it easy to fix the connecting clamp to the external structure.
[0025] 2. By incorporating countersunk holes, adjusting bolts, and adjusting clips, the inner diameter of the pipe clamp can be reduced, increasing the applicability of the connecting clamp and making it easier for workers to use the pipe clamp to fix pipes with smaller diameters.

[0030] The present application will be further described in detail below with reference to the accompanying drawings.
[0031] This application discloses a corrosion-resistant connecting hoop for deep-sea oil extraction, referring to... Figure 1 The connecting hoop includes a rectangular mounting plate 1, on which a mounting block 2 is provided. Fixing holes 11 are provided on both sides of the mounting plate 1 along its length. Multiple fixing holes 11 are provided at intervals along the length of the mounting plate 1. A pipe clamp 3 is welded to the end face of the mounting block 2 away from the mounting plate 1. Two pipe clamps 3 are provided at intervals along the length of the mounting block 2. The entire connecting hoop is coated with a corrosion-resistant coating.
[0032] When using this connecting clamp, use bolts or other methods to pass through the fixing holes 11 and fix the mounting plate 1 to the external structure. Open the two pipe clamps 3 and fix the pipes to be connected into the two pipe clamps 3 respectively. Connect the two pipes to each other and fix the two pipes to be connected through the two pipe clamps 3. This makes it easy for the staff to connect the two pipes to each other. Fixing the mounting plate 1 to the external structure through the fixing holes 11 can increase the stability of the pipe connection and increase the stability of the connecting clamp for fixing the pipe connection. The multiple spaced fixing holes 11 make it easy for the staff to select the installation method according to the site environment and to fix the connecting clamp to the external structure.
[0033] Reference Figure 1 and Figure 2 The pipe clamp 3 includes a connecting block 31 welded to the mounting block 2. A fixing hoop 32 is integrally formed on the connecting block 31. A movable hoop 33 is hinged to one end of the fixing hoop 32. The movable hoop 33 and the fixing hoop 32 can close to form a ring. A fixing block 34 is integrally formed at one end of the movable hoop 33. A strip groove 341 is opened on the side of the fixing block 34 near the mounting plate 1. One end of the strip groove 341 is connected to the side wall of the fixing block 34. A fastening bolt 35 is welded on the connecting block 31. The part of the fastening bolt 35 away from the connecting block 31 is located in the strip groove 341. One end of the fastening bolt 35 is connected to the connecting block 31, and the other end is threaded with a nut 36. The nut 36 is located on the side of the fixing block 34 away from the connecting block 31.
[0034] When using this connecting clamp, place the pipe inside the fixed clamp 32 and rotate the movable clamp 33 until it closes with the fixed clamp 32. Rotate the fastening bolt 35 until one end of the fastening bolt 35 is located in the strip groove 341. Then, thread the nut 36 to the end of the fastening bolt 35 away from the fixed block 34. Tighten the nut 36 to bring the fixed block 34 closer to the connecting block 31. At the same time, move the movable clamp 33 closer to the fixed clamp 32 to clamp and fix the pipe inside the pipe clamp 3. This increases the stability of the pipe clamp 3 in fixing the pipe and makes it easier for workers to connect the pipe.
[0035] Reference Figure 1 and Figure 2 Both the fixed hoop 32 and the movable hoop 33 have countersunk holes 37 on opposite sides. An adjusting bolt 371 is installed in the countersunk hole 37. The head of the adjusting bolt 371 passes through the countersunk hole 37 and is threadedly connected to an adjusting clip 38. The two adjusting clips 38 are respectively fitted to the inner walls of the fixed hoop 32 and the movable hoop 33 and can be closed into a ring. A sealing plug 372 is embedded in the opening of the countersunk hole 37. In this embodiment, the sealing plug 372 is made of elastic material.
[0036] When using this connecting clamp, the two adjusting clips 38 are fixed to the fixed clamp 32 and the movable clamp 33 respectively by adjusting bolts 371. This can reduce the inner diameter of the pipe clamp 3, increase the applicable range of the connecting clamp, and make it easier for workers to use the pipe clamp 3 to fix pipes with smaller diameters. The sealing plug 372 embedded at the opening of the countersunk hole 37 can reduce the corrosion caused by seawater and microorganisms entering the gap between the adjusting bolt 371 and the fixed clamp 32 or the movable clamp 33, and ensure the safety and stability of the connecting clamp during operation.
[0037] Reference Figure 2 A protective cap 361 is machined on the side of the nut 36 away from the connecting block 31. When this connecting clamp is used, the protective cap 361 can protect the connection between the nut 36 and the fastening bolt 35, reducing the risk of loosening of the connection due to corrosion.
[0038] Reference Figure 1 and Figure 2 The fixing block 34 has an anti-detachment groove 342 on the side opposite to the connecting block 31. The anti-detachment groove 342 is located at the opening of the strip groove 341 and communicates with the strip groove 341. The width of the opening of the anti-detachment groove 342 is greater than the diameter of the nut 36. When this connecting clamp is used, the nut 36 can be embedded in the anti-detachment groove 342, which can increase the stability of the nut 36 on the fixing block 34, and at the same time increase the stability of the pipe clamp 3 in fixing the pipe.
[0039] Reference Figure 1 and Figure 2 A washer 362 is bonded to the side of the nut 36 that is in contact with the fixing block 34. The inner wall of the washer 362 is in contact with the peripheral wall of the fastening bolt 35. A sealing block 343 is embedded in the strip groove 341. The sealing block 343 is snapped into the strip groove 341, and the side wall of the sealing block 343 is in contact with the inner wall of the strip groove 341, the peripheral wall of the fastening bolt 35, and the connecting block 31. In this embodiment, the sealing plug 372 is a sealing block made of elastic material. When this connecting clamp is used, the washer 362 can reduce the risk of the nut 36 loosening due to pipeline vibration, and at the same time protect the connection between the nut 36 and the fastening bolt 35, reducing the risk of connection loosening caused by corrosion. The sealing block 343 can protect the peripheral wall of the fastening bolt 35 and the internal thread of the nut 36, reducing the risk of connection loosening caused by corrosion.
[0040] Reference Figure 2 Both the fixed clamp 32 and the movable clamp 33 have integrally formed reinforcing ribs 39 on the opposite side. When using this connecting clamp, the reinforcing ribs 39 can increase the overall structural strength of the pipe clamp 3 and ensure that the sleeve can firmly clamp the pipe.
[0041] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
