[0028] First Embodiment

[0029] Please refer to the following: Figure 1 , Figure 2 and Figure 3 ,in, Figure 1 A schematic diagram of the structure of a first embodiment of a marine oil control pipe that is easy to connect to the present invention; Figure 2 for Figure 1 The diagram shows a cross-sectional view of the structure. Figure 3 for Figure 1 The enlarged schematic diagram of part A is shown. A marine oil control tubing that is easy to connect includes: a connecting mechanism 1, the connecting mechanism 1 including a connecting sleeve 11, the tubing mechanism 2 being connected inside the connecting sleeve 11, the tubing mechanism 2 including a conical ring 22, the conical ring 22 being embedded inside the connecting sleeve 11;

[0030] Positioning mechanism 3, the positioning mechanism 3 includes positioning groove 33, the positioning groove 33 is connected to the inside of the connecting sleeve 11;

[0031] The sealing mechanism 4 includes a sealing plate 41, which is installed inside the connecting sleeve 11.

[0032] The function of the connecting mechanism 1 is to connect and fix. The connecting sleeve 11 is cylindrical and hollow inside, and multiple holes are arrayed on the circumference near both ends. The function of the oil pipe mechanism 2 is to connect and realize the transportation of oil. The conical ring 22 is conical in shape, and its maximum circumference can be just embedded inside the connecting sleeve 11. The function of the positioning mechanism 3 is to connect and position. The positioning groove 33 is ring-shaped, and there are two positioning grooves 33 inside each connecting sleeve 11. The function of the sealing mechanism 4 is to realize the sealing and opening inside the positioning mechanism 3 through transmission. The sealing plate 41 is L-shaped, and there are two sets in each pair. In each set, the two sealing plates 41 have a sealing groove and a sealing strip respectively on the near end. When the two sealing plates 41 are connected, the sealing strip is embedded in the sealing groove, which plays the role of sealing the connection.

[0033] The connecting sleeve 11 has a fixing bolt 12 on its internal thread, and the surface of the conical ring 22 is connected to a tube 21, with both ends of the tube 21 embedded in the positioning groove 33.

[0034] The diameter and thickness of the tube body 21 are just right to be fitted inside the positioning groove 33. By embedding one end of each of the two tube bodies 21 into the two positioning grooves 33 inside the connecting sleeve 11, the two tube bodies 21 are connected and positioned to the connecting sleeve 11. A conical ring 22 is connected to the outer surface of each tube body 21 near both ends.

[0035] The surface of the conical ring 22 is provided with a threaded hole 23, the fixing bolt 12 is threaded into the inside of the threaded hole 23, and the inner ring 31 is connected inside the connecting sleeve 11.

[0036] The conical ring 22 has the same number of threaded holes 23 as the surface of the connecting sleeve 11. When the conical ring 22 is fully embedded in the connecting sleeve 11, the positioning groove 33 corresponds one-to-one with the holes on the surface of the connecting sleeve 11. Then, the fixing bolt 12 is rotated through the hole on the surface of the connecting sleeve 11 and the thread is turned into the inside of the threaded hole 23, thus realizing the connection and fixation between the tube body 21 and the connecting sleeve 11.

[0037] The inner ring 31 is connected to the outer ring 32, the positioning groove 33 is formed on the surface between the inner ring 31 and the positioning groove 33, and the sealing plate 41 is embedded in the inner ring 31.

[0038] The inner ring 31 is fixedly connected to the inside of the connecting sleeve 11. An outer ring 32 is formed by opening positioning grooves 33 on the circumference of both ends of the inner ring 31. An annular groove is opened inside the inner ring 31, and the sealing plate 41 is slidably embedded in the annular groove. One end of the sealing plate 41 is embedded in the inside of the connecting sleeve 11 through the surface of the outer ring 32. The transmission block 42 is fixedly connected to the end of the sealing plate 41 embedded in the connecting sleeve 11, and the connection surface with the conical ring 22 is an inclined surface. When the conical ring 22 is embedded in the inside of the connecting sleeve 11, the inclined surface of the conical ring 22 connects with the inclined surface of the transmission block 42, giving the transmission block 42 an outward pushing force, thereby driving the sealing plate 41 to slide outward, realizing the opening of the inside of the inner ring 31.

[0039] The sealing plate 41 is connected to two ends of a transmission block 42, the transmission block 42 is connected to the surface of the conical ring 22, the connecting sleeve 11 is connected to a spring rod 43, and the sealing plate 41 is connected to the surface of the spring rod 43.

[0040] The spring rod 43 is a sliding rod with a spring connected to its surface. The two sealing plates 41 are connected by a plate, which is slidably connected to the surface of the sliding rod and connected to one end of the spring. When the conical ring 22 is embedded in the connecting sleeve 11, the two sealing plates 41 are connected under the thrust of the spring, thus sealing the inside of the inner ring 31.

[0041] The working principle of the marine oil control tubing that is easy to connect provided by this utility model is as follows:

[0042] During installation, one end of the tube 21 is inserted into the positioning groove 33. During this process, the conical ring 22 is connected to the surface of the transmission block 42, giving the two transmission blocks 42 an outward pushing force. The transmission block 42 then drives the two sealing plates 41 to move towards each other, and the inner ring 31 is gradually opened until one end of the tube 21 is completely embedded in the positioning groove 33. Finally, the fixing bolt 12 is threaded into the threaded hole 23 through the surface of the connecting sleeve 11, and the tube 21 and the connecting sleeve 11 are connected and fixed. During disassembly, the fixing bolt 12 is threaded out from the inside of the threaded hole 23 and the surface of the connecting sleeve 11, and then the tube 21 is pulled. One end of the tube 21 gradually moves out of the positioning groove 33, and the surface of the conical ring 22 gradually separates from the transmission block 42. Under the elastic force of the spring rod 43, the two sealing plates 41 are pushed to move relative to each other. When one end of the conical ring 22 is completely separated from the positioning groove 33, the two sealing plates 41 are connected, realizing the sealing inside the inner ring 31 and preventing oil leakage.

[0043] Compared with related technologies, the marine oil control tubing provided by this utility model, which is easy to connect, has the following advantages:

[0044] This utility model provides a marine oil control pipe that is easy to connect. The pipe can be connected to the pipe mechanism 2 through the connecting mechanism 1. During installation, the sealing plate 41 can be opened by the connection and transmission of the positioning mechanism 3 and the sealing mechanism 4, so as to realize the connection of the oil circuit. When disassembling, the sealing mechanism 4 can achieve the sealing of the inner ring 31 by the sealing plate 41 through its own elasticity, thus preventing the risk of oil leakage caused by the valve not being closed.

[0045] Second Embodiment

[0046] Please refer to the following: Figure 4 Based on the first embodiment of this application which provides a marine oil control pipeline that is easy to connect, the second embodiment of this application proposes another marine oil control pipeline that is easy to connect. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0047] Specifically, the second embodiment of this application provides a marine oil control pipe that is easy to connect, wherein the outer surface of the connecting sleeve 11 is provided with a shock-absorbing mechanism 5, the shock-absorbing mechanism 5 includes a shock-absorbing component 51, and the shock-absorbing component 51 is connected to the outer surfaces of both ends of the connecting sleeve 11.

[0048] The number of shock-absorbing components 51 is multiple, and they can be spring shock absorbers, air pressure dampers and rubber shock absorbers, etc., preferably spring shock absorbers. The support component 52 consists of a base plate with two plates connected to the top, and the other ends of the two shock-absorbing components 51 are respectively connected to the surfaces of the two connecting plates.

[0049] The shock-absorbing component 51 is used to absorb and dampen the vibration force on the surface of the connecting sleeve 11. The other end of the shock-absorbing component 51 is connected to a support component 52, and the bottom surfaces of both ends of the support component 52 are connected to fixing pins 53.

[0050] The support component 52 has two holes on the left and right ends of the bottom plate, through which the fixing pin 53 can be inserted into the seabed to fix the connecting sleeve 11.

[0051] The working principle of the marine oil control tubing that is easy to connect provided by this utility model is as follows:

[0052] After the two tubes 21 are connected, the support component 52 is placed in a suitable position, and then the fixing pin 53 is inserted into the seabed through the surface of the support component 52. The connecting sleeve 11 is then fixed to the seabed. When waves pass over the surface of the connecting sleeve 11, the surface of the connecting sleeve 11 generates vibration force. The damping component 51 absorbs and dampens the vibration, thereby reducing the vibration force on the surface of the connecting sleeve 11.

[0053] Compared with related technologies, the marine oil control tubing provided by this utility model, which is easy to connect, has the following advantages:

[0054] This utility model provides a marine oil control pipe that is easy to connect. By inserting the fixing pin 53 into the seabed, the connecting sleeve 11 can be fixed at the same time. The vibration of the connecting sleeve 11 can be reduced by the shock-absorbing component 51, thereby increasing the stability of the connection between the two pipe bodies 21 and reducing the risk of vibration breakage.

[0055] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
