Description

Technical Field

[0001] The utility model relates to the technical field of conductive slip rings, in particular to a pressure-bearing underwater conductive slip ring. Background Art

[0002] Conductive slip rings, as precision rotary electrical connectors, are widely used in electromechanical equipment that requires unrestricted continuous or intermittent rotation while also transmitting power and signals from a fixed position to a rotating position. With technological advancements and industrial development, the application of conductive slip rings continues to expand, initially from military and aerospace fields to civilian use, industrial automation, medical equipment, robotics, and other fields.

[0003] When operating underwater, conventional slip rings often experience water seepage due to poor sealing, which can corrode internal components, shorten their service life, and even cause electrical failures. Furthermore, as underwater operations increase in depth, slip rings must withstand higher water pressures, which can easily damage their internal structures and affect their proper operation.

[0004] Therefore, a pressure-bearing underwater conductive slip ring has been developed that can be used underwater to prevent water from seeping in and causing damage, and has a strong pressure-bearing capacity to prevent internal damage caused by excessive underwater pressure. Utility Model Content

[0005] In order to overcome the shortcomings of traditional conductive slip rings that often cause water to seep into the interior due to poor sealing when working underwater, and that as the depth of underwater operation increases, the conductive slip rings need to withstand higher water pressure, which easily causes damage to the internal structure of the conductive slip rings, the utility model provides a pressure-bearing underwater conductive slip ring that can be used underwater to prevent damage caused by water seepage and has strong pressure-bearing capacity to prevent internal damage caused by excessive underwater pressure.

[0006] The technical implementation scheme of the utility model is: a pressure-bearing underwater conductive slip ring, including a stator housing, a connecting pipe, a valve, a protective shell and a slip ring assembly. The left side of the upper part of the stator housing is connected to a connecting pipe, the connecting pipe is rotatably connected to the valve, the right side of the stator housing is connected to the protective shell, and the slip ring assembly is arranged in the stator housing.

[0007] More preferably, the stator housing has a hollow structure.

[0008] More preferably, the valve is provided with a handle.

[0009] More preferably, the slip ring assembly includes a slip ring rotor, a rotor connecting line, a first bearing, a second bearing, a stator conductor housing, a copper column and a connecting stator conductor. The stator conductor housing is sleeved inside the stator housing, the first bearing is connected to the inner side of the left portion of the stator conductor housing, the second bearing is connected to the inner side of the right portion of the stator conductor housing, the slip ring rotor is rotatably connected between the first bearing and the second bearing, the slip ring rotor is connected to the rotor connecting line, a plurality of copper columns are connected to the inner side of the stator conductor housing, all of the copper columns are in contact with the slip ring rotor, the upper and lower parts of the stator conductor housing are connected to the connecting stator conductor, and all of the connecting stator conductors pass through the stator housing.

[0010] More preferably, a plurality of sliding grooves are provided on the slip ring rotor.

[0011] More preferably, a threading hole is opened on the stator housing, and the diameter of the threading hole is consistent with the thickness of the stator connecting wire.

[0012] Compared with the existing technology, the utility model has the following advantages: the utility model forms a closed environment between the stator shell and the protective shell, and then connects the connecting pipe with the inflation pipe. When the valve is opened, inert gas is filled into the stator shell to change the air pressure inside the stator shell, so that it can be used underwater and prevent water from seeping in and causing damage. It also has a strong pressure-bearing capacity and prevents internal damage caused by excessive underwater pressure. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] A pressure-bearing underwater conductive slip ring, such as Figures 1-6 As shown, it includes a stator housing 1, a connecting pipe 10, a valve 11, a protective shell 2 and a slip ring assembly. The connecting pipe 10 is connected to the left side of the upper part of the stator housing 1. The stator housing 1 is a hollow structure. The connecting pipe 10 is rotatably connected to the valve 11. The valve 11 is provided with a handle for easy rotation. The protective shell 2 is connected to the right side of the stator housing 1, and a slip ring assembly is provided in the stator housing 1.

[0022] The slip ring assembly includes a slip ring rotor 3, a rotor connecting line 30, a first bearing 4, a second bearing 5, a stator conductor housing 6, a copper column 7 and a connecting stator conductor 8. The stator conductor housing 6 is sleeved inside the stator housing 1, the first bearing 4 is connected to the inner side of the left part of the stator conductor housing 6, and the second bearing 5 is connected to the inner side of the right part of the stator conductor housing 6. The slip ring rotor 3 is rotatably connected between the first bearing 4 and the second bearing 5. The slip ring rotor 3 is connected to the rotor connecting line 30. Twenty-four copper columns 7 are connected to the inner side of the stator conductor housing 6. The copper columns 7 are all in contact with the slip ring rotor 3. Twelve slide grooves are clamped on the slip ring rotor 3 to facilitate contact with the copper columns 7. The upper and lower parts of the stator conductor housing 6 are connected to the connecting stator conductor 8, and the connecting stator conductor 8 all pass through the stator housing 1.

[0023] When using the present invention, first move the device to the use area of the conductive slip ring, then connect the stator conductor 8 to the electrical circuit, and at the same time connect the slip ring rotor 3 to the electrical circuit through the rotor connecting line 30. When the slip ring is driven by an external machine to rotate, the slip ring rotates between the first bearing 4 and the second bearing 5. When the slip ring rotor 3 rotates, the power in the electrical system is still transmitted to the slip ring rotor 3, and then transmitted to the stator conductor housing 6 through the copper column 7, and then transmitted back to the electrical circuit through the stator conductor connecting wire 8 on the stator conductor. During the transmission process, the stator conductor 8 remains stationary, thereby enabling the slip ring to be rotated in the external mechanical part. When the device rotates, the stator conductor 8 is prevented from being entangled and knotted. When the device needs to be used underwater, a closed environment is formed between the stator housing 1 and the protective shell 2 to prevent water from entering and causing damage to the slip ring rotor 3 and the stator conductor housing 6. At the same time, the connecting pipe 10 is docked with the inflation pipe, and the valve 11 is opened. Inert gas is filled into the stator housing 1 to change the air pressure in the stator housing 1, thereby improving the pressure resistance of the stator housing 1, so that the stator housing 1 protects the internal parts, thereby achieving the effect of being able to be used underwater, preventing water from seeping in and causing damage, and having a strong pressure-bearing capacity to prevent internal zero damage caused by excessive underwater pressure.
