Description

Technical Field

[0001] This utility model relates to the field of single-point mooring, and more particularly to a fluid transfer structure based on a single-point mooring system. Background Technology

[0002] Single-point mooring systems are mainly used for mooring oil tankers and fluid transfer, such as crude oil loading and unloading. Its core is to allow the tanker to rotate freely at sea according to the direction of wind, waves and currents, while maintaining the continuity of fluid transfer. The fluid transfer structure is the fluid transfer component that connects the tanker and the subsea pipeline, including rotary joints, pipeline layout, sealing system, etc.

[0003] In existing technologies, the sea is rough and the pressure on fluid transport pipelines is high when encountering emergencies such as typhoons. This can easily cause the fluid transport pipeline to break in the middle, resulting in leakage of the transported fluid and subsequent pollution of the ocean. It is also difficult to achieve self-locking of broken pipelines in the absence of power supply, thereby reducing the loss of fluid leakage.

[0004] To address the aforementioned technical shortcomings, a solution is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a fluid transfer structure based on a single-point mooring system to address the aforementioned technical deficiencies.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] The fluid transfer structure based on the single-point mooring system includes symmetrically distributed lower valve bodies. A circular groove is formed at the center of the lower valve body. An upper valve body is provided above the lower valve body. An integrally formed mounting box is fixedly provided above the upper valve body. A positioning column is fixedly connected inside the mounting box. A valve core is rotatably connected inside the circular groove. A connecting rod at the top of the valve core passes through the mounting hole and is fixedly fitted with a spur gear.

[0008] Preferably, a first slot is provided inside the lower valve body on one side of the circular groove, and a second slot is provided inside the lower valve body on the other side of the circular groove. Sealing rings are embedded inside the lower valve body, the first slot, and the second slot. A limit groove is provided at one end of the lower valve body, and a limit strip is also provided at one end of the lower valve body for fixed connection.

[0009] Preferably, the upper valve body and the lower valve body are fixed by bolts. The lower part of the upper valve body is also provided with a first slot, a circular slot and a second slot corresponding to the lower valve body. The two sides of the inside of the mounting box are fixed with integrally formed abutments. The center of the upper valve body is provided with a mounting hole. One end of the mounting box is also provided with symmetrically distributed sliding grooves.

[0010] Preferably, the mounting box is further provided with a mounting strip inside, and the mounting strip has a positioning hole inside. The positioning post is inserted into the positioning hole. The other end of the mounting strip is inserted into the interior of another mounting box and is slidably connected to the other mounting box. A rack is fixedly connected to one side of the other end of the mounting strip, and the rack meshes with a spur gear in the other mounting box.

[0011] Preferably, a first pipe is provided between the lower valve bodies, and mounting rings are fixed at both ends of the first pipe. The mounting rings are located inside the first slot, and a second pipe is provided on the outside of the lower valve body.

[0012] Preferably, one end of the second pipe is provided with a fixedly connected mounting ring two, which is located inside the second slot. The wall thickness of the first pipe is less than that of the second pipe, and a cover plate is fixedly installed on the top of each mounting box by bolts.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention connects the device body to a fluid transmission pipeline. In the event of rough seas, the first pipeline, with its thinner wall than the second, will break first. After the first pipeline breaks, the two lower valve bodies at both ends move away from each other, causing the mounting strips in the two mounting boxes to be pulled out of the other mounting box. Simultaneously, the rack and spur gear mesh, causing the spur gear to rotate 90 degrees, which in turn rotates the valve core to close the transmission channel. This allows the device to achieve self-locking in the event of pipeline breakage without power, thereby reducing losses caused by damage to the fluid transmission pipeline.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 - Figure 5 As shown, this utility model is a fluid transfer structure based on a single-point mooring system, including symmetrically distributed lower valve bodies 1. A circular groove 13 is provided at the center of the lower valve body 1. A first slot 12 is provided inside the lower valve body 1 on one side of the circular groove 13, and a second slot 14 is provided inside the lower valve body 1 on the other side of the circular groove 13.

A limit groove 15 is provided at one end of the lower valve body 1, and a fixedly connected limit strip 16 is also provided at one end of the lower valve body 1.

[0024] An upper valve body 17 is provided above the lower valve body 1. The upper valve body 17 is fixed to the lower valve body 1 by bolts. The lower part of the upper valve body 17 is also provided with a first slot 12, a circular groove 13 and a second slot 14 corresponding to the lower valve body 1. An integrally formed mounting box 18 is fixedly provided above the upper valve body 17. An integrally formed abutment 19 is fixedly provided on both sides inside the mounting box 18. A mounting hole 21 is provided at the center of the upper valve body 17. A fixedly connected positioning post 20 is provided inside the mounting box 18. A symmetrically distributed sliding groove 22 is also provided at one end of the mounting box 18.

[0025] The inside of the circular groove 13 is provided with a rotatably connected valve core 23. The connecting rod at the top of the valve core 23 passes through the mounting hole 21 and is fixedly provided with a spur gear 24. The inside of the mounting box 18 is also provided with a mounting strip 25. The inside of the mounting strip 25 is provided with a positioning hole 26. The positioning pin 20 is inserted into the positioning hole 26 to fix the mounting strip 25. The other end of the mounting strip 25 is inserted into the inside of another mounting box 18 and is slidably connected to the other mounting box 18. A rack 27 is fixedly connected to one side of the other end of the mounting strip 25. The rack 27 meshes with the spur gear 24 in the other mounting box 18. The number of teeth of the rack 27 is one-quarter of that of the spur gear 24.

[0026] A first pipe 29 is provided between the lower valve bodies 1. Both ends of the first pipe 29 are fixedly provided with mounting rings 28. The mounting rings 28 are located inside the first slot 12. A second pipe 30 is provided on the outside of the lower valve body 1. One end of the second pipe 30 is fixedly connected with a second mounting ring. The second mounting ring is located inside the second slot 14. The wall thickness of the first pipe 29 is less than the wall thickness of the second pipe 30. A cover plate 31 is fixedly installed on the top of the mounting box 18 by bolts.

[0027] The working process and principle of this utility model are as follows:

[0028] In use, first connect this device to the fluid transmission pipeline. Then, if there are large waves at sea, the first pipeline 29 will break first because its wall is thinner than the second pipeline 30. After the first pipeline 29 breaks, the two lower valve bodies 1 at both ends of the first pipeline 29 will move away from each other, so that the mounting strips 25 in the two mounting boxes 18 will be pulled out from the other mounting box 18. At the same time, the rack 27 meshes with the spur gear 24, which drives the spur gear 24 to rotate 90 degrees, thereby driving the valve core 23 to rotate 90 degrees to close the transmission channel, thus reducing the losses caused by damage to the fluid transmission pipeline.
