High-temperature slip rings play a very important role in the entire high-temperature machine, just like the heart, so there is a high demand for high-temperature conductive slip rings. However, in order to ensure the normal operation of high-temperature machines, the quality requirements for this high-temperature slip ring are very high.

The two metal shells need to be completely separated during maintenance, and the disassembly and assembly process is cumbersome and inefficient. In addition, the disconnection and maintenance of mechanical equipment brings great inconvenience to the fault detection of mechanical equipment. Therefore, the utility model provides a conductive slip ring suitable for high temperature environments to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0018] The following is only a preferred embodiment of the present invention, and the protection scope is not limited to this embodiment. All technical solutions under the concept of the present invention should belong to the protection scope of the present invention. At the same time, it should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.

[0019] See Figures 1 to 4 As shown, a conductive slip ring suitable for high temperature environment comprises an end cover 1, at least two connecting columns 2 are fixedly connected between the two end covers 1, a rotor body 3 is rotatably embedded in the middle of the lower end cover 1, a plurality of stator bodies 4 are mounted on the connecting column 2, the stator bodies 4 are arranged corresponding to the rotor bodies 3, and a lead wire 5 electrically connected to the stator body 4 is fixedly embedded on the upper side of the end cover 1;

[0020] Specifically, the rotor body 3 is connected to a transmission line, which is connected to the mechanical equipment. The lead wire 5 transmits the signal to each stator body 4. The stator body 4 is connected to different annular conductive positions on the rotor body 3, so that the rotor body 3 can transmit signals during rotation. It is worth noting that the connection method between the stator body 4 and the rotor body 3 can be one of contact communication (see: patent announcement number CN201360094Y for details) or contactless communication (see: patent announcement number CN115037368B for details).

[0021] Further, a heat insulation component 6 is detachably connected between the outer edges of the two end covers 1, and the heat insulation component 6 includes two half shells 61, and the adjacent sides of the two half shells 61 are provided with grooves 62, and a sealing strip 63 is clamped and fixed between the grooves 62. The upper and lower end surfaces of the half shells 61 are provided with arc grooves 64, and the inner edges of the arc grooves 64 are provided with bosses 65. The upper and lower sides of the half shells 61 are fixed with second connecting plates 66;

[0022] Specifically, the sealing strip 63 is made of high temperature resistant rubber material. When the two half shells 61 are pressed against each other, the sealing strip 63 is effectively squeezed, which effectively improves the sealing performance of the connection between the two half shells 61. The sealing strip 63 is an overall "concave" shaped structure, and its two ends are respectively in contact with two sealing rings 68.

[0023] Furthermore, the heat insulation assembly 6 further comprises a concave ring 67 located at the outer edge of the end cover 1, and a sealing ring 68 is sleeved in the concave ring 67, and the sealing ring 68 is arranged to abut against the boss 65;

[0024] Specifically, the sealing ring 68 is made of high temperature resistant rubber material. When the end cover 1 and the half shell 61 are pressed against each other, the sealing ring 68 is fully squeezed, which effectively improves the sealing performance of the connection between the end cover 1 and the half shell 61 .

[0025] Furthermore, both ends of the end cover 1 are fixedly connected with a first connecting plate 11, and the first connecting plate 11 is fixed to the adjacent second connecting plate 66 by screws;

[0026] Specifically, the middle parts of the first connecting plate 11 and the second connecting plate 66 are both provided with perforations to facilitate connection with bolts and nuts. After tightening the nuts, the two half shells 61 and the end cover 1 and the half shells 61 can be tightly attached to each other to prevent leakage.

[0027] Furthermore, the end cover 1 and the half shell 61 together form a hollow cylindrical structure;

[0028] Specifically, the internal and external environments of the conductive slip ring can be isolated in all directions, and the semicircular half shell 61 is easy to disassemble without affecting the connection between the stator body 4 and the rotor body 3. The mechanical equipment does not need to be disconnected for maintenance, which brings convenience to the fault detection of the mechanical equipment.

[0029] Furthermore, the end cover 1 and the half shell 61 are both made of porous ceramic materials;

[0030] Specifically, the thermal conductivity of the ceramic itself is low, and the gas filled in the porous structure greatly enhances the thermal insulation performance of the material, playing a good thermal insulation role.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein.
