Description

Technical Field

[0001] The utility model relates to the technical field of four-channel liquid metal dielectric slip rings, in particular to a four-channel liquid metal dielectric slip ring. Background Art

[0002] The four-way liquid metal dielectric slip ring is based on the transmission of liquid metal between the rotating part and the stationary part.

[0003] For example, a multi-media multi-channel fluid slip ring with the application publication number "CN118066399A" adopts two or more rotating seals of different diameters between the fluid slip ring channels, and the rotor sealing mating surface is provided with segmented steps of corresponding different diameters. The channels with smaller pipe diameters are arranged at the lower part of the stator, which reduces the processing depth of the upper and lower pipe channels with corresponding smaller diameters in the rotor. It has the advantages of high sealing reliability, long service life, good fault tolerance, strong environmental adaptability, low processing cost, and high processing and assembly process performance. However, in the use of liquid metal medium slip rings, the overall length is long and it is integrated, which cannot be disassembled and carried, which is more troublesome. Moreover, the length cannot be adjusted, resulting in the liquid metal medium slip ring being able to meet only one working condition, resulting in the use limitations of the liquid metal medium slip ring. At the same time, the liquid metal medium slip ring is not easy to carry. Utility Model Content

[0004] The utility model aims to solve the problems that liquid metal dielectric slip rings have usage limitations and are inconvenient to carry, and proposes a four-channel liquid metal dielectric slip ring.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A four-channel liquid metal dielectric slip ring is designed, including an outer cover and a first double-channel liquid metal dielectric slip ring. The left side of the inner wall of the outer cover is plugged into the right side of the outer wall of the first double-channel liquid metal dielectric slip ring. The left and right sides of the top of the outer cover are respectively connected to fixed structures, and the lower right side of the first double-channel liquid metal dielectric slip ring is connected to a plug-in structure.

[0007] Preferably, the fixing structure includes a screw and a ball, the outer wall of the screw is threadedly connected to the top of the outer cover, the top of the screw is fixed to the bottom of the ball, the outer wall of the screw is rotatably connected to a bent plate, and the outer wall of the bent plate is fitted with the outer wall of the outer cover.

[0008] Preferably, a second dual-path liquid metal medium slip ring is inserted into the right side of the inner wall of the outer cover.

[0009] Preferably, a second through hole is processed below the outer wall of the outer cover.

[0010] Preferably, the top liquid injection ports of the first dual-channel liquid metal medium slip ring and the second dual-channel liquid metal medium slip ring are both plugged with plugs.

[0011] Preferably, the plug-in structure includes a cylindrical pin and an inner core, the left side of the outer wall of the cylindrical pin is plugged into the lower right groove of the first dual-channel liquid metal medium slip ring, the inner wall of the cylindrical pin is fixedly connected to the outer wall of the inner core, the right side of the outer wall of the cylindrical pin is plugged into the lower left groove of the second dual-channel liquid metal medium slip ring, and the top two ends of the cylindrical pin are respectively fixed with inclined blocks, and the outer walls of the two inclined blocks are respectively plugged into the lower right groove of the first dual-channel liquid metal medium slip ring and the lower left groove of the second dual-channel liquid metal medium slip ring.

[0012] The utility model proposes a four-way liquid metal medium slip ring, which has the following beneficial effects: the ball drives the screw to rotate downward on the top of the outer cover through the fixed structure, and the outer wall of the rotating screw rotates through the bearing of the outer wall of the bent plate. As the screw rotates downward, the bent plate moves downward until the bottom of the outer wall of the bent plate blocks the outer side of the liquid metal medium slip ring. At this time, the bent plate restricts the outer wall of the liquid metal medium slip ring, preventing the liquid metal medium slip ring from separating from the outer cover. At the same time, it can also be disassembled to form a four-way liquid metal medium slip ring, eliminating the use limitations of the liquid metal medium slip ring and facilitating the lacing of the liquid metal medium slip ring.

DETAILED DESCRIPTION

[0018] The present invention will be further described below with reference to the accompanying drawings:

[0019] Example 1:

[0020] See also Figure 1-4 : In this embodiment, a four-channel liquid metal dielectric slip ring includes an outer cover 1 and a first dual-channel liquid metal dielectric slip ring 4. The left side of the inner wall of the outer cover 1 is plugged into the right side of the outer wall of the first dual-channel liquid metal dielectric slip ring 4. The left and right sides of the top of the outer cover 1 are respectively connected to fixed structures 2, and the lower right side of the first dual-channel liquid metal dielectric slip ring 4 is connected to a plug-in structure 3.

[0021] The fixing structure 2 includes a screw 201 and a ball 202. The outer wall of the screw 201 is threadedly connected to the top of the outer cover 1. The screw 201 is subjected to force and rotates up and down through the top of the outer cover 1. The top of the screw 201 is fixedly connected to the bottom of the ball 202. The ball 202 is convenient for driving the screw 201 to rotate up and down. The outer wall of the screw 201 is rotatably connected to a bent plate 203. The upper part of the outer wall of the screw 201 is subjected to force and rotates through the bearing at the top of the bent plate 203. The outer wall of the bent plate 203 is in contact with the outer wall of the outer cover 1.

[0022] The ball 202 in the fixing structure 2 is used to rotate downward with the screw 201 on the top of the outer cover 1. The outer wall of the rotating screw 202 rotates through the bearing on the outer wall of the bent plate 203. As the screw 202 rotates downward, the bent plate 203 is moved downward with it until the bottom of the outer wall of the bent plate 203 blocks the outside of the liquid metal medium slip ring. At this time, the bent plate 203 restricts the outer wall of the liquid metal medium slip ring to prevent the liquid metal medium slip ring from separating from the outer cover 1. At the same time, it can also be disassembled to form a four-way liquid metal medium slip ring, eliminating the use limitations of the liquid metal medium slip ring and facilitating the lacing of the liquid metal medium slip ring.

[0023] A second dual-path liquid metal medium slip ring 5 is inserted into the right side of the inner wall of the outer cover 1. The models of the first dual-path liquid metal medium slip ring 4 and the second dual-path liquid metal medium slip ring 5 are selected according to usage requirements. A second through hole 7 is processed at the lower part of the outer wall of the outer cover 1. The top liquid filling ports of the first dual-path liquid metal medium slip ring 4 and the second dual-path liquid metal medium slip ring 5 are both inserted with plugs 8, and the plugs 8 are made of rubber.

[0024] The plug-in structure 3 includes a cylindrical pin 301 and an inner core 302. The left side of the outer wall of the cylindrical pin 301 is plugged into the lower right groove of the first dual-channel liquid metal medium slip ring 4. The inner wall of the cylindrical pin 301 is fixedly connected to the outer wall of the inner core 302. The inner core 302 is made of carbon fiber to ensure strength while reducing the weight of the cylindrical pin 301. The right side of the outer wall of the cylindrical pin 301 is plugged into the lower left groove of the second dual-channel liquid metal medium slip ring 5. The top two ends of the cylindrical pin 301 are respectively fixed with inclined blocks 303, which are made of rubber. The outer walls of the two inclined blocks 303 are respectively plugged into the lower right groove of the first dual-channel liquid metal medium slip ring 4 and the lower left groove of the second dual-channel liquid metal medium slip ring 5.

[0025] Working principle:

[0026] Liquid metal dielectric slip ring installation:

[0027] First, pull the multiple plugs 8 upward to disengage the multiple plugs 8 from the injection ports on the top of the first double-pass liquid metal medium slip ring 4 and the second double-pass liquid metal medium slip ring 5 respectively, then send the liquid metal through the injection port, and then insert the multiple plugs 8 back into the injection port, and then plug the left side of the outer wall of the cylindrical pin 301 with the right side below the first double-pass liquid metal medium slip ring 4, and then plug the right side of the outer wall of the first double-pass liquid metal medium slip ring 4 with the left side of the outer cover 1, and plug the second double-pass liquid metal medium slip ring 5 with the right side of the outer cover 1. At this time, the right side of the outer wall of the cylindrical pin 301 is plugged with the left side below the second double-pass liquid metal medium slip ring 5, and the inclined block 303 can increase the connection friction with the liquid metal medium slip ring. At this time, the first double-pass liquid metal medium slip ring 4 and the second double-pass liquid metal medium slip ring 5 complete the preliminary installation.

[0028] The ball 202 rotates downward with the screw 201 on the top of the outer cover 1, and the outer wall of the rotating screw 202 rotates through the bearing on the outer wall of the bent plate 203. As the screw 202 rotates downward, the bent plate 203 moves downward with it until the bottom of the outer wall of the bent plate 203 blocks the outside of the liquid metal medium slip ring. At this time, the bent plate 203 restricts the outer wall of the liquid metal medium slip ring, preventing the liquid metal medium slip ring from separating from the outer cover 1, forming a four-way liquid metal medium slip ring.

[0029] The bottom of the left and right sides of the outer cover 1 can be fitted with the external connection surface, and then the bolt is threaded through the second through hole 7 on the side that is not fitted with the connection, and then the bolt is threadedly connected with the connection to complete the fixing of the outer cover 1, thereby fixing the liquid metal medium slip ring inside the outer cover 1.

[0030] Example 2:

[0031] See also Figure 1-4In this embodiment, a four-way liquid metal medium slip ring further includes a first through hole 6, and the first through hole 6 is processed on the lower boss of the inner wall of the outer cover 1.

[0032] Working principle:

[0033] After the first double-pass liquid metal medium slip ring 4 and the second double-pass liquid metal medium slip ring 5 are installed with the outer cover 1, two bolts are respectively threaded through the threaded openings below the outer walls of the first double-pass liquid metal medium slip ring 4 and the second double-pass liquid metal medium slip ring 5, and then threadedly connected with the inner wall of the first through hole 6.
