[0002] In actual applications, high-voltage disconnectors are often directly exposed to the environment and are often eroded by light, wind, sand and rain in the environment. In addition, they are rarely operated, which can easily cause jamming of the transmission mechanism and the operating mechanism. It is necessary to regularly perform status detection and analysis on the operating mechanism of the high-voltage disconnector. During the detection, the rotation angle of the main shaft needs to be measured and analyzed.

[0003] The existing spindle angle detection device usually fixes the detection unit on the shaft end of the spindle. When replacing or disassembling the detection unit, the spindle vertical tube needs to be destroyed, which is very complicated to operate. In addition, it is impossible to measure the angle of the spindle in operation after installation, which reduces the practicality of the high-voltage disconnector spindle angle detection device. To this end, we provide a high-voltage disconnector spindle angle detection device to solve the above technical problems. Utility Model Content

DETAILED DESCRIPTION

[0020] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0021] Reference Figure 1 and Figure 2 A high-voltage disconnector main shaft rotation angle detection device comprises a box body 1, a detection mechanism 2 is arranged above the box body 1, the detection mechanism 2 comprises a main shaft body 201, the main shaft body 201 is rotatably connected to the inside of the box body 1, an auxiliary block 202 is arranged outside the main shaft body 201, a clamping assembly 203 is arranged inside the auxiliary block 202, the clamping assembly 203 comprises a bidirectional threaded rod 209, the bidirectional threaded rod 209 is rotatably connected to the inside of the auxiliary block 202, and the outer surface of the bidirectional threaded rod 209 is threadedly connected to two moving blocks 2 10. The side surfaces of the two moving blocks 210 that are close to each other are fixedly connected with a clamping plate 211. The side surfaces of the two clamping plates 211 that are close to each other are fixedly connected with anti-skid rubber blocks 212 that are arranged at equal distances. The two moving blocks 210 are made to move closer to or farther from each other by forward or reverse rotation of the bidirectional threaded rod 209. The moving blocks 210 can simultaneously drive the clamping plates 211 and the anti-skid rubber blocks 212 to move. The clamping plates 211 are used to fix the spindle body 201. At the same time, the anti-skid rubber blocks 212 can increase the stability after fixation.

[0022] Reference Figure 2 An auxiliary bearing 213 is sleeved on the outer surface of the bidirectional threaded rod 209, and the auxiliary bearing 213 is embedded in the inside of the auxiliary block 202. The auxiliary bearing 213 can reduce the friction generated by the bidirectional threaded rod 209 during rotation, making the bidirectional threaded rod 209 more sensitive during rotation. At the same time, it can also reduce the wear speed of the bidirectional threaded rod 209 and increase the service life of the bidirectional threaded rod 209.

[0023] Reference Figure 2The end of the bidirectional threaded rod 209 away from the auxiliary block 202 is fixedly connected with a rotating handle 215, and the interior of the auxiliary block 202 is fixedly connected with a stabilizing rod 214. The two moving blocks 210 are both slidably connected to the outer surface of the stabilizing rod 214. The rotating handle 215 can provide a good force point for the bidirectional threaded rod 209, increasing the convenience when the bidirectional threaded rod 209 needs to be rotated. The stabilizing rod 214 can improve the force position of the moving block 210 and increase the stability of the moving block 210 during work.

[0024] Reference Figure 1 and Figure 3 A main gear 204 is fixedly connected to the top of the auxiliary block 202, and four fixing rods 216 are fixedly connected to the upper surface of the auxiliary block 202. The top ends of the four fixing rods 216 are fixedly connected to the bottom end of the main gear 204. The fixing rods 216 play an auxiliary role, providing good support between the main gear 204 and the auxiliary block 202, and also increasing the height of the main gear 204, thereby improving the convenience of the main gear 204 when in use.

[0025] Reference Figure 1 and Figure 4 A sub-gear 206 is arranged above the housing 1, and the outer surfaces of the main gear 204 and the sub-gear 206 are connected to a power transmission belt 207 for rotation together. A rotating bearing 218 is inlaid inside the sub-gear 206, and the inner wall of the inner ring of the rotating bearing 218 is fixedly connected to the support rod 205, and the bottom end of the support rod 205 is fixedly connected to the mounting block 217, and the bottom end of the mounting block 217 is snap-fitted with the upper surface of the housing 1. The support rod 205 plays a role in supporting the sub-gear 206, and the mounting block 217 can increase the firmness of the support rod 205 to prevent the support rod 205 from breaking after long-term use. The rotating bearing 218 can reduce the friction of the sub-gear 206 during rotation, so that the sub-gear 206 is more sensitive during rotation.

[0026] Reference Figure 1 and Figure 4 A rotary photoelectric encoder 208 is fixedly connected to the upper surface of the sub-gear 206, a cabinet door 219 is movably hinged on the front of the box body 1, and an auxiliary handle 220 is fixedly connected to the front of the cabinet door 219. The cabinet door 219 can improve the convenience when the interior of the box body 1 needs to be repaired or inspected. The cabinet door 219 can be opened or closed by pulling the auxiliary handle 220, and the cleanliness of the box body 1 can also be increased.

[0027] Working principle: When in use, first rotate the handle 215 to make the bidirectional threaded rod 209 rotate forward, the auxiliary bearing 213 can improve the sensitivity of the bidirectional threaded rod 209 when rotating, and then the two moving blocks 210 drive the clamping plate 211 to approach each other, the stabilizing rod 214 can increase the force position of the moving block 210 when moving, increase the stability of the moving block 210, thereby clamping the main shaft body 201, the anti-slip rubber block 212 can improve the firmness of the clamping plate 211 during clamping, and then install the fixing rod 216 to the appropriate position on the upper surface of the box body 1, so as to conveniently fix or disassemble the main shaft body 201, and also can install the running main shaft body 201, when opening and closing the switch. The main shaft body 201 will drive the auxiliary block 202 to rotate, and then the main gear 204 will rotate. At this time, the main gear 204 can drive the sub-gear 206 to rotate on the outer surface of the support rod 205 by cooperating with the power transmission belt 207. The rotating bearing 218 can improve the rotation effect of the sub-gear 206. When the sub-gear 206 rotates, it can drive the rotating photoelectric encoder 208 to rotate at the same time. The rotating photoelectric encoder 208 is used to accurately measure the rotation angle of the main shaft body 201, thereby providing core data for the status inspection of the high-voltage disconnector. When the detection device needs to be disassembled, the rotating handle 215 is rotated to reverse it, so that the moving block 210 drives the clamping plates 211 away from each other.

[0028] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
