Technical Field

The invention relates to a self-cleaning slip ring free of disassembly and assembly.

Background

With the rapid development of domestic aviation and aerospace technologies, the requirements on the performance, reliability and accuracy of navigation equipment are continuously improved. In response to this, the slip ring is becoming more and more highly required as the most important component for signal transmission and reliable.

Slip rings, also known as rotary electrical interfaces, electrical rotary joints, may be used in any electrical system that requires unlimited continuous rotation to transmit power and data signals from a stationary structure to a rotating structure. And a device for transmitting electric signals and electric energy between the rotating part and the static part of the equipment by utilizing sliding or rolling contact, electrostatic coupling or electromagnetic coupling of the conductive parts. Slip rings are typically mounted on the rotating shaft of the device, and after extended use, the brushes and brush slots present wear debris and dirt. Debris and dirt affect the contact resistance between the brush filaments and the brush channels and thus the transmission of signals. After a long period of use, the slip ring must be cleaned. When cleaning, the slip ring leads are all cut off, removed from the equipment, and the slip ring cavity is opened for cleaning. This process is very labor intensive and requires several days for the fastest cleaning. The processes of breaking a wire, detaching a slip ring cavity, cleaning a loop, installing the slip ring cavity, installing the slip ring, wiring and the like are required, the process is complex, the process equipment is in a shutdown state, and the user equipment cannot be used.

Disclosure of Invention

The invention aims to provide a disassembly-free self-cleaning slip ring, which is used for solving the problems in the background technology and has the characteristics of rapidness and simplicity in operation and low cleaning cost.

The technical scheme is that the disassembly-free self-cleaning slip ring comprises a slip ring rotor and a slip ring stator, a slip ring loop is arranged between the slip ring rotor and the slip ring stator, mounting holes are formed in the slip ring stator and are axially arranged, a rotating main shaft is arranged in the mounting holes, cleaning sponges are symmetrically arranged on two sides of the rotating main shaft, alcohol diversion holes connected with the cleaning sponges are formed in two sides of the rotating main shaft, and a rotating handle is arranged at one end of the rotating main shaft.

Furthermore, the rotating main shaft is of a hollow structure and is axially arranged in the mounting hole, and cleaning sponges fixedly mounted on two sides of the rotating main shaft are in contact with the slip ring loop.

Advantageous effects

Compared with the prior art, the invention has the following advantages.

After the slip ring is used for a long time, the slip ring can be cleaned without detaching the slip ring, the cleaning sponge is switched to the position of a slip ring loop to be cleaned of the slip ring by rotating the rotating handle, alcohol is filled through the rotating main shaft and the alcohol diversion hole, and the slip ring can be cleaned through rotation.

Drawings

The present invention will be described in further detail with reference to the accompanying drawings.

FIG. 1 is a structural cross-sectional view of the present invention;

fig. 2 is a side view of the structure of the present invention.

Detailed Description

The invention is further described with reference to the following examples and the accompanying drawings.

As shown in fig. 1 and 2, the disassembly-free self-cleaning slip ring comprises a slip ring rotor 2 and a slip ring stator 3, a slip ring loop 6 is arranged between the slip ring rotor 2 and the slip ring stator 3, a mounting hole 7 arranged along the axial direction is arranged in the slip ring stator 3, a rotating main shaft 1 is arranged in the mounting hole 7, cleaning sponges 4 are symmetrically arranged on two sides of the rotating main shaft 1, alcohol diversion holes 8 connected with the cleaning sponges 4 are arranged on two sides of the rotating main shaft 1, and a rotating handle 5 is arranged at one end of the rotating main shaft 1.

The rotating main shaft 1 is of a hollow structure, the rotating main shaft 1 is axially arranged in the mounting hole 7, and the cleaning sponges 4 fixedly mounted on two sides of the rotating main shaft 1 are in contact with the slip ring loop 6.

When the cleaning device is specifically implemented, after the slip ring is used for a long time, the cover plate 9 arranged on the end face of the slip ring is opened, the rotating main shaft 1 is rotated through the rotating handle 5, the rotating main shaft 1 drives the cleaning sponge 4 to be positioned at the position of the slip ring loop 6, at the moment, the cleaning sponge 4 is tightly contacted with the slip ring loop 6, then alcohol is injected from one end of the rotating main shaft 1, and the alcohol flows into the cleaning sponge 4 through the alcohol guide hole 8 to play a role of cleaning liquid.

When the slip ring rotates, the cleaning sponge 4 can adsorb the scraps and dirt on the slip ring loop 6, after the slip ring is cleaned for multiple circles, the rotating handle 5 is rotated to enable the cleaning sponge 4 to restore to the initial position, and at the moment, the cleaning sponge 4 is not in contact with the slip ring loop 6, so that the slip ring loop is cleaned; when the cleaning is needed for the second time, the rotating handle 5 can be rotated reversely, and the cleaning sponge 4 on the other side of the rotating main shaft 1 is in contact with the slip ring loop 6 to clean the slip ring loop.
