Description

Technical Field

[0001] The invention relates to a disassembly-free self-cleaning slip ring. Background Art

[0002] With the rapid development of domestic aviation and aerospace technology, the requirements for the performance, reliability and accuracy of navigation equipment are constantly increasing. Correspondingly, as the most important component for signal transmission, the slip ring has higher and higher index requirements and reliability.

[0003] Slip rings, also known as rotary electrical interfaces and electrical rotary joints, can be used in any electrical system that requires unlimited continuous rotation to transmit power and data signals from a fixed structure to a rotating structure. A device that uses sliding or rolling contact, electrostatic coupling or electromagnetic coupling of conductive parts to transmit electrical signals and electrical energy between the rotating parts and the stationary parts of the equipment. Slip rings are generally installed on the rotating shaft of the equipment. After long-term use, the brushes and brush grooves will be worn, debris and dirt. Debris and dirt affect the contact resistance between the brush wire and the brush groove, which in turn affects the transmission of signals. After long-term use, the slip rings must be cleaned. When cleaning, all the slip ring leads must be cut off, removed from the equipment, and the slip ring cavity must be opened for cleaning. This process is very labor-intensive and the cleaning work takes at least several days. It is necessary to disconnect the wires, remove the slip rings, remove the slip ring cavity, clean the ring channel, install the slip ring cavity, install the slip ring and connect the wires. The process is complicated. During this process, the equipment is in a shutdown state and the user's equipment cannot be used. Summary of the invention

[0004] The purpose of the present invention is to provide a self-cleaning slip ring that does not require disassembly and assembly to solve the problems in the above-mentioned background technology, and the invention has the characteristics of quick and simple operation and low cleaning cost.

[0005] The technical solution adopted to achieve the above-mentioned purpose is a self-cleaning slip ring that does not require disassembly and assembly, including a slip ring rotor and a slip ring stator, a slip ring track is arranged between the slip ring rotor and the slip ring stator, an axially arranged mounting hole is arranged in the slip ring stator, a rotating main shaft is arranged in the mounting hole, cleaning sponges are symmetrically installed on both sides of the rotating main shaft, alcohol diversion holes connected to the cleaning sponges are arranged on both sides of the rotating main shaft, and a rotating handle is installed at one end of the rotating main shaft.

[0006] Furthermore, the rotating main shaft is a hollow structure, and the rotating main shaft is axially arranged in the mounting hole, and the cleaning sponges fixedly mounted on both sides of the rotating main shaft are in contact with the slip ring track.

[0007] Beneficial Effects

[0008] Compared with the prior art, the present invention has the following advantages.

[0009] The present invention can clean the slip ring without disassembling it after long-term use. The user only needs to turn the rotating handle to switch the cleaning sponge to the position of the slip ring track that needs to be cleaned, and add alcohol by rotating the main shaft and the alcohol guide hole. The slip ring can be cleaned by rotating it. The cleaning is simple and convenient, the workload is small, and a lot of manpower, material resources and time costs are saved. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0011] Figure 1 It is a structural cross-sectional view of the present invention;

[0012] Figure 2 It is a structural side view of the present invention. DETAILED DESCRIPTION

[0013] The present invention will be further described below in conjunction with embodiments and drawings.

[0014] like Figure 1 , 2 As shown, a self-cleaning slip ring which does not require disassembly and assembly comprises a slip ring rotor 2 and a slip ring stator 3, a slip ring channel 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 installed on both sides of the rotating main shaft 1, alcohol guide holes 8 connected to the cleaning sponges 4 are arranged on both sides of the rotating main shaft 1, and a rotating handle 5 is installed at one end of the rotating main shaft 1.

[0015] The rotating main shaft 1 is a hollow structure and is axially arranged in the mounting hole 7 . The cleaning sponges 4 fixedly mounted on both sides of the rotating main shaft 1 are in contact with the slip ring track 6 .

[0016] When the present invention is implemented, after the slip ring is used for a long time, the cover plate installed on the end face of the slip ring is opened, and the rotating spindle 1 is rotated by rotating the handle 5, so that the rotating spindle 1 drives the cleaning sponge 4 to be in the position of the slip ring track 6. At this time, the cleaning sponge 4 is in close contact with the slip ring track 6, and then alcohol is added from one end of the rotating spindle 1. The alcohol flows into the cleaning sponge 4 through the alcohol guide hole 8, and acts as a cleaning liquid.

[0017] When the slip ring rotates, the cleaning sponge 4 will absorb the debris and dirt on the slip ring track 6. After several rounds of cleaning, the rotating handle 5 is turned to restore the cleaning sponge 4 to its initial position. At this moment, the cleaning sponge 4 does not touch the slip ring track 6, and the cleaning of the slip ring track is completed. When a second cleaning is needed, the rotating handle 5 can be rotated in the opposite direction, and the cleaning sponge 4 on the other side of the rotating spindle 1 can be used to touch the slip ring track 6 to clean the slip ring track.
