[0029] The present utility model will be further described below in conjunction with the accompanying drawings and implementation manners.

[0030] Please refer to Figure 1 , Figure 2 and Figure 3 , wherein, Figure 1 is a schematic structural diagram of a preferred embodiment of an easily installable offshore oil control oil pipe provided by the present utility model; Figure 2 is Figure 1 a schematic internal connection structure diagram of the connector shown; Figure 3 is Figure 2 an enlarged schematic diagram of part A shown. An easily installable offshore oil control oil pipe includes: an oil pipeline 1, with first connection assemblies 2 provided at both ends of the oil pipeline 1. The first connection assemblies 2 include connectors 21, the connectors 21 are fixedly installed at both ends of the oil pipeline 1, and a sealing ring 22 is fixedly installed on the inner surface of the connectors 21;

[0031] A first fixing assembly 3, which is arranged inside the connector 21;

[0032] A second connection assembly 4, which is arranged inside the connector 21;

[0033] An oil circuit conversion assembly 5, which is arranged on the outer surface of the connector 21;

[0034] A second fixing assembly 6, which is arranged inside the connector 21;

[0035] The third connecting component 7 is disposed inside the second connecting component 4.

[0036] There are three connecting sleeves fixedly connected to the outside of the connector 21. Two connecting sleeves on the same horizontal line are fixedly connected to one end of two adjacent petroleum pipelines 1. Two sealing rings 22 are fixedly installed inside each connector 21, and are respectively fixedly installed at the joints of the three connecting sleeves, which has the function of sealing. The function of the first fixing component 3 is to connect and fix. The function of the second connecting component 4 is to connect and change the flow path of the petroleum. The function of the oil path conversion component 5 is to connect with the second connecting component 4 to play a role in temporarily transporting the petroleum. The function of the second fixing component 6 is to connect and fix.

[0037] The first fixing component 3 includes a fixing hole 31, which is opened on the inner surface of the connector 21. A retracting hole 32 is opened on the inner surface of the connector 21 at the bottom of the fixing hole 31. A fixing bolt 33 is threadedly embedded inside the connector 21 at the bottom of the retracting hole 32.

[0038] Two fixing holes 31 and two fixing bolts 33 are opened on the inner surface of another connecting sleeve of each connector 21, and threaded holes are opened at the left and right ends. The two fixing bolts 33 are respectively threadedly connected inside the two threaded holes.

[0039] The second connecting component 4 includes a sealing cap 41, which is movably installed inside the connector 21. An oil delivery port 42 is opened on the surface of one end of the sealing cap 41.

[0040] The sealing cap 41 is slidably embedded inside the connector 21 and another connecting sleeve, and a hole is opened on the surface of the end close to the inside of the connector 21. When the sealing cap 41 slides into the innermost part of the connector 21, the sealing cap 41 blocks one connection port of the two horizontal connecting sleeves, and the oil delivery port 42 communicates with the other connection port.

[0041] The oil path conversion component 5 includes a conversion pipe 51. Both ends of the conversion pipe 51 are movably embedded inside the connector 21 and the sealing cap 41. Thrust blocks 52 are fixedly connected to both ends of the conversion pipe 51.

[0042] The conversion pipe 51 is formed by connecting multiple pipes into a U shape. The two pipes at both ends are connected to the sealing cap 41 through the inside of the vertical connecting sleeves in the two connectors 21, so that the petroleum flows into the inside of the conversion pipe 51, changing the flow path of the petroleum. And two thrust blocks 52 are fixedly connected to the surfaces of both ends. One end of the two thrust blocks 52 close to each other is a slope.

[0043] The second fixing component 6 includes a connecting block 61 which is movably installed inside the sealing cap 41. The thrust block 52 is movably connected to the surface of the connecting block 61. One end of the connecting block 61 is fixedly connected to a fixing block 62 which is movably embedded inside the fixing hole 31. A fixing spring 63 is fixedly connected to the surface of the connecting block 61.

[0044] One end of the sealing cap 41 close to the inside of the connector 21 is provided with a chute. Two connecting blocks 61 are slidably embedded inside each chute. The bottoms of the two connecting blocks 61 are inclined surfaces and are attached to the surfaces of the two thrust blocks 52. One ends of the two fixing blocks 62 are respectively fixedly connected to the far ends of the two connecting blocks 61. The two connecting blocks 61 are connected by a fixing spring 63. Under the elastic force of the fixing spring 63, a thrust is given to the two connecting blocks 61, so that the two fixing blocks 62 are embedded inside the two fixing holes 31, thereby realizing the fixation of the sealing cap 41 inside the connector 21.

[0045] The third connecting component 7 includes a connecting pin 71 which is movably installed inside the sealing cap 41. The connecting pin 71 is movably embedded inside the retraction hole 32. A connecting spring 72 is movably installed on the outer surface of the connecting pin 71. One end of the connecting pin 71 is movably connected to a connecting hole 73 which is opened on the surface of the thrust block 52.

[0046] Two third connecting components 7 are arranged inside each sealing cap 41. The two third connecting components 7 are respectively arranged at the left and right ends of the sealing cap 41 close to the inside of the connector 21. One end of the connecting pin 71 which is a rod is fixedly connected to a block. The connecting spring 72 is movably sleeved on the outer surface of the rod. When the connecting pin 71 and the retraction hole 32 are on the same horizontal line, the elastic force of the connecting spring 72 gives a push to the connecting pin 71, so that the other end of the connecting pin 71 is embedded inside the retraction hole 32. When the conversion pipe 51 pushes the sealing cap 41, the connecting pin 71 slides towards the inside of the sealing cap 41 under the pressure of the inner surface of the connector 21, and the two wedge-shaped blocks are embedded inside the two connecting holes 73, thereby realizing the connection and fixation of the conversion pipe 51 and the sealing cap 41.

[0047] The working principle of an easily installable offshore oil control oil pipe provided by the present utility model is as follows:

[0048] When it is necessary to replace the oil pipeline 1, first rotate the two fixing bolts 33 so that their threads come out of the surface of the sealing cap 41. Then, insert the two ends of the conversion pipe 51 into the inside of the connectors 21 at both ends of the oil pipeline 1 to be replaced. During this process, the two thrust blocks 52 are respectively connected to the two connecting blocks 61, and give the two connecting blocks 61 a relative push to make the two connecting blocks 61 slide relatively, and drive the two fixing blocks 62 out of the inside of the two fixing holes 31. The sealing cap 41 loses its fixing force. Continuing to push the conversion pipe 51 will drive the sealing cap 41 to slide into the connector 21. One end of the connecting pin 71 will then disengage from the inside of the retraction hole 32, and the pressure from the inner surface of the connector 21 will cause the other end of the connecting pin 71 to be embedded into the inside of the connection hole 73, so that the sealing cap 41 is connected and fixed to the oil circuit conversion assembly 5 until the oil outlet 42 is at the connection between the connector 21 and the two oil pipelines 1. The sealing cap 41 will then seal the connection between one of the oil pipelines 1 and the connector 21. Then rotate the fixing bolt 33 so that its thread enters the inside of the conversion pipe 51 to fix the conversion pipe 51, change the flow path of the oil circuit and transport the oil through the inside of the conversion pipe 51. The inside of the oil pipeline 1 to be replaced is no longer in oil circulation, and then it can be replaced. After the replacement is completed, pull the conversion pipe 51 outwards. Since one end of the connecting pin 71 is embedded in the inside of the connection hole 73, the conversion pipe 51 drives the sealing cap 41 to slide outwards. When one end of the connecting pin 71 slides to the same horizontal line as the retraction hole 32, the connecting pin 71 is no longer under the pressure of the inner surface of the connector 21, and the elastic force of the connecting spring 72 will push the connecting pin 71 to be embedded into the inside of the retraction hole 32 and disengage from the inside of the connection hole 73. The conversion pipe 51 and the sealing cap 41 are no longer connected and fixed. Continuing to pull the conversion pipe 51 outwards, the thrust block 52 gradually disengages from the surface of the connecting block 61, and the elastic force of the fixing spring 63 will push the fixing block 62 to be embedded into the inside of the fixing hole 31, thus realizing the fixing of the sealing cap 41 and the disassembly of the conversion pipe 51.

By arranging a second connection component 4 inside the first connection component 2, the two ends of the oil circuit conversion component 5 can be embedded into the inside of the first connection component 2 and connected to it, and the connection and fixation can be realized through the first fixing component 3 and the second fixing component 6, so as to realize the conversion of the oil circuit, facilitate the replacement of the oil pipeline 1, and there is no need to install a repair clamp on the outer surface of the oil pipeline 1, which is convenient for disassembly, replacement and installation.
