[0021] The gyroscope circuit sealing device disclosed in this utility model is mainly used in scenarios where the existing gyroscope sealing cover is complicated to disassemble and assemble, cannot be adapted to the surface of soft transmission lines, and is prone to water ingress during operation, affecting the accuracy of testing.

[0023] Reference Figures 1-5 In a preferred embodiment, the sealing cover assembly 2 includes: a cover 204, which is disposed on the outer wall of the gyroscope body 3, and the outer wall of the gyroscope body 3 is provided with sliding grooves at equal intervals, and the cover 204 is slidably connected to the inside of the sliding grooves; and fixing blocks 206, which are fixedly connected to one end of the cover 204 at equal intervals, and the fixing blocks 206 are provided with screw holes on the opposite side of the gyroscope body 3, and bolts 205 are screwed into the screw holes.

One end of the sealing rubber sleeve 209 near the fixing block 206 is fixedly connected to the inner wall of the cover 204, and the outer wall of the sealing rubber sleeve 209 is fixedly connected to a plurality of pressure rods 210.

[0026] In this solution, the sealing cover assembly 2 further includes: a connecting pipe shell 215, which is disposed on the side of the cover 204 away from the fixing block 206. The connecting pipe shell 215 and the cover 204 are fixedly connected by two connecting plates 203. Fixing rings 213 are fixedly connected to both sides of the connecting pipe shell 215. One fixing ring 213 is located between the connecting pipe shell 215 and the cover 204. The two sides of the other fixing ring 213 are fixedly connected to the connecting pipe shell 215 and the cover 204 respectively. The other fixing ring 213 is located on the side of the connecting pipe shell 215 away from the cover 204.

[0027] In this solution, the sealing cover assembly 2 further includes: a telescopic spring 217, wherein multiple telescopic springs 217 are fixedly connected at equal intervals to one side of the inner wall of two fixed rings 213, and the other end of the multiple telescopic springs 217 fixedly connected at equal intervals to the inner wall of two fixed rings 213 is fixedly connected to a ratchet plate 212; and a push ring 202, wherein two push rings 202 are slidably connected to the inside of push slots opened on opposite sides of two fixed rings 213, and one end of the two push rings 202 is fixedly connected to the corresponding two ratchet plates 212.

[0028] In this solution, the sealing cover assembly 2 further includes: a sealing ring 207, disposed inside the fixing ring 213 away from the cover 204. A groove is formed on one side of the fixing ring 213 away from the cover 204. The sealing ring 207 is slidably connected inside the groove. Multiple locking blocks on one side of the sealing ring 207 abut against the ratchet teeth of the corresponding ratchet plate 212. Multiple pull ropes 208 are fixedly connected to the inner wall of the sealing ring 207. The other ends of the pull ropes 208 pass through the fixing ring 213 and are fixedly connected to the high-toughness rubber ring 201. The inner wall of the high-toughness rubber ring 201 contacts the outer wall of the transmission line 1. One side of the high-toughness rubber ring 201... The other end of the sealing rubber sleeve 209 is fixedly connected; the fastening ring 214 is set inside the fixing ring 213 near the cover 204. A sliding groove is opened on one side of the fixing ring 213 near the cover 204. The fastening ring 214 is slidably connected inside the sliding groove. Multiple locking blocks on one side of the fastening ring 214 abut against the ratchet teeth of the corresponding ratchet plate 212. A rotating slot is opened on the inner wall of the fixing ring 213. A fastening rope 216 is fixedly connected to the inner wall of the fastening ring 214. The fastening rope 216 moves inside the rotating slot. The other end of the fastening rope 216 is fixedly connected to the outer wall of the sealing rubber sleeve 209.

[0029] When sealing the circuit interface of the gyroscope body 3, a sealing rubber sleeve 209, a sealing ring 207, a pull rope 208, a high-toughness rubber ring 201, a fastening ring 214, and a fastening rope 216 are set up. By rotating the sealing ring 207, the originally wound pull rope 208 is slowly released. The high-toughness rubber ring 201, which is fixedly connected to multiple pull ropes 208, continuously shrinks under the action of elastic stress until it is fitted onto the outer wall of the transmission line 1. At the same time, multiple pressure rods 210, which are fixedly connected to the sealing rubber sleeve 209, are compressed by the spring 211. Make the end of the sealing rubber sleeve 209 near the high-toughness rubber ring 201 fit against the outer wall of the transmission line 1. Then rotate the fastening ring 214. As the fastening ring 214 rotates, the fastening rope 216, which is fixedly connected to the fastening ring 214 and the sealing rubber sleeve 209, wraps around and seals the end of the sealing rubber sleeve 209 that is fitted against the outer wall of the transmission line 1. This structure can adapt to the soft outer wall of the transmission line 1, thereby better sealing the interface. At the same time, the sealing cover assembly 2 is movably connected to the surface of the gyroscope body 3, which can seal the interface at any time, and does not affect normal operation when not sealed.

[0030] Working principle: When sealing the circuit interface of the gyroscope body 3, the worker pushes the sealing cover assembly 2 until the screw hole on the fixing block 206 aligns with the screw hole on the gyroscope body 3. Simultaneously, the sealing rubber ring 6, fixed to the outer wall of one end of the gyroscope body 3, tightly fits against the sealing cover assembly 2 to prevent water from seeping in through the sliding groove during operation. Then, multiple bolts 205 are screwed into the screw holes to firmly fix the sealing cover assembly 2. After fixing the sealing cover assembly 2, the sealing ring 207 is rotated first. As 7 rotates, the originally coiled pull rope 208 slowly releases. The high-toughness rubber ring 201, fixedly connected to multiple pull ropes 208, continuously shrinks under elastic stress until it fits snugly against the outer wall of the transmission line 1. Simultaneously, multiple pressure rods 210 fixedly connected to the sealing rubber sleeve 209, due to the compression of the spring 211, cause the end of the sealing rubber sleeve 209 near the high-toughness rubber ring 201 to adhere to the outer wall of the transmission line 1. Then, the fastening ring 214 is rotated. With the rotation of the fastening ring 214, the fastening ring 21... 4. The fastening rope 216, which is fixedly connected to the sealing rubber sleeve 209, wraps around and seals one end of the sealing rubber sleeve 209 that is in contact with the outer wall of the transmission line 1. Then, the rotation of the fastening ring 214 is stopped. Under the action of the ratchet plate 212, it is prevented that the rebound will cause the seal to fail. When retrieving the sealing cover assembly 2, the worker first pushes the two push rings 202 to make the ratchet plate 212 no longer engage and fix the sealing ring 207 and the fastening ring 214. Then, the fastening ring 214 is rotated first to make the fastening rope 216 no longer engage the transmission line. The sealing rubber sleeve 209 on the surface is wrapped and sealed. Then, the sealing ring 207 is rotated to make the pull rope 208 continuously wind up, so that the inner diameter of the high-toughness rubber ring 201 is continuously stretched and fits against the inner wall of the fixing ring 213. After that, the worker screws the bolt 205 and pushes the sealing cover assembly 2 away from the transmission line 1. During this process, as the pressure rod 210 is retracted, the sealing rubber sleeve 209 fits against the inner wall of the cover 204 to prevent jamming when the sealing cover assembly 2 slides. At the same time, the sealing rubber sleeve 209 is retracted.

[0031] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
