Description

Technical Field

[0001] The utility model relates to the technical field of power cabins, in particular to a titanium alloy deep-sea pressure-resistant power cabin with high sealing performance. Background Art

[0002] With the continuous development of deep-sea exploration technology, the requirements for the sealing and pressure resistance of internal components of deep-sea equipment are increasing day by day. As a key component of deep-sea equipment, the sealing and pressure resistance of the power cabin are directly related to the operation safety and stability of the whole equipment.

[0003] The sealing structure of traditional deep-sea power cabins is relatively simple. Mostly, bolts are used to connect the cover end and the cabin body to achieve the effects of sealing and fixing. However, the deep-sea environment is complex and changeable, and a power cabin with relatively stronger sealing performance is needed to better protect the internal power supply. Therefore, developing a titanium alloy deep-sea pressure-resistant power cabin with high sealing performance and strong pressure resistance is of great significance for ensuring the normal operation of deep-sea equipment. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem that in the prior art, the sealing structure of the deep-sea power cabin is relatively simple. Mostly, bolts are used to connect the cover end and the cabin body to achieve the effects of sealing and fixing. However, the deep-sea environment is complex and changeable, and a power cabin with relatively stronger sealing performance is needed to better protect the internal power supply. Thus, a titanium alloy deep-sea pressure-resistant power cabin with high sealing performance is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A titanium alloy deep-sea pressure-resistant power cabin with high sealing performance, including a shell, a bottom cover end and a top cover end, the bottom cover end and the top cover end are respectively located at both ends of the shell;

[0007] Two outer ring shells for connecting the bottom cover end and the top cover end with the shell, the two outer ring shells are respectively located at both ends of the outer wall of the shell;

[0008] Two connecting rings for increasing the firmness between the bottom cover end and the top cover end and the shell, the two connecting rings are respectively located at both ends of the shell;

[0009] Two sealing rings for ensuring the sealing performance between the bottom cover end and the top cover end and the shell, the two sealing rings are respectively located on the sides of the bottom cover end and the top cover end close to the shell.

[0010] In a possible design, outer annular protrusions are provided at both ends of the outer wall of the shell, and inner annular protrusions are provided at the ends of the inner walls of the outer ring shells far from the shell.

[0011] In a possible design, the outer ring housing is fixedly sleeved on the outer wall of the outer annular convex part. A partition groove is provided between the inner annular convex part and the outer annular convex part. The two connecting rings are respectively located inside the two partition grooves, and the connecting rings are rotatably arranged inside the partition grooves.

[0012] In a possible design, bosses are provided on both the bottom end and the top end of the cover on the side close to the housing.

[0013] In a possible design, the outer walls of the bottom end and the top end of the cover are respectively in threaded fit with the inner walls of the two inner annular convex parts.

[0014] In a possible design, a plurality of limiting rods are fixedly provided on both the bottom end and the top end of the cover on the side close to the housing. A plurality of limiting holes are formed on the surface of the connecting ring. The plurality of limiting rods are respectively matched with the plurality of limiting holes. A plurality of second threaded holes are formed on the surfaces of both the bottom end and the top end of the cover. A plurality of first threaded holes are formed on the surface of the connecting ring. The plurality of first threaded holes are respectively matched with the plurality of second threaded holes on the same side.

[0015] In a possible design, both ends of the inner wall of the housing cavity are provided as outer frustum-shaped inclined surfaces. One end of the boss close to the housing is provided as an inner frustum-shaped inclined surface. The inner frustum-shaped inclined surface is matched with the outer frustum-shaped inclined surface. An annular groove is formed on the outer wall of the inner frustum-shaped inclined surface. The sealing ring is sleeved on the outer wall of the annular groove. The sealing ring is matched with the inner wall of the outer frustum-shaped inclined surface.

[0016] In this application, during specific use, after aligning the limiting rods on the surfaces of the bottom end and the top end of the cover with the limiting holes, rotate and threadedly install them inside the outer ring housing. At this time, the connecting ring will be driven to rotate together by the limiting rods to ensure that the first threaded holes and the second threaded holes are connected. When the installation of the bottom end and the top end of the cover is completed by rotation, then use bolts to install through the first threaded holes and the second threaded holes to achieve connection, ensuring its firmness. And when installing, the sealing ring on the side of the boss will first touch the outer frustum-shaped inclined surface, and then be squeezed until the inner frustum-shaped inclined surface and the outer frustum-shaped inclined surface are fitted together, thereby ensuring the sealing performance of the connection.

[0017] In this utility model, for the titanium alloy deep-sea pressure-resistant power cabin with high sealing performance, through the outer ring housing, the bottom end and the top end of the cover can be initially installed at both ends of the housing, thereby achieving initial installation and sealing, which can be realized only through simple threading;

[0018] In this utility model, for the titanium alloy deep-sea pressure-resistant power cabin with high sealing performance, through the connecting ring, the connection between the bottom end and the top end of the cover and the housing can be further increased, thereby increasing the overall firmness of the power cabin;

[0019] In the present utility model, during use, the bottom end and the top end of the cover are respectively threadedly installed in the outer ring shells at both ends, and the preliminary installation can be completed. Then, bolts are used to connect with the connecting ring, which can enhance the overall firmness.

[0020] During installation, the sealing ring will be compressed. Then, the inner conical slope and the outer conical slope fit tightly together to ensure that the sealing ring can better play its sealing role. BRIEF DESCRIPTION OF THE DRAWINGS
