[0033] Among them, there are multiple groups of detection mechanisms 13, and the multiple groups of detection mechanisms 13 are evenly arranged. The detection mechanism 13 includes a detection component 131 for detecting the degree of shaking of the base 1 and the above devices and a receiving component 132 for receiving signals. Since the outdoor high-voltage disconnector 1325 is mostly installed on a column and is exposed to the air as a whole, after long-term use, the environmental and climatic conditions have a great impact on its operating reliability and stability. The detection mechanism 13 detects whether the connection between the base 1 and the above devices and the bottom plate 12 is disconnected, and determines whether repair is needed based on the degree of shaking. When the degree of shaking reaches the degree that requires repair, it will be detected and received by the receiving component 132, so that the staff can receive the signal to locate and get repair. When an accident occurs, the signal can be transmitted to the protective mechanism 14. The protective mechanism 14 increases the friction area between the base 1 and the ground, reduces vibration and jitter, and minimizes damage to sudden falls.

Preferably, the receiving component 132 is provided with two groups and is symmetrically arranged, the receiving component 132 includes a connecting plate 1321, a cylinder 1322, an undulating rod 1323, a receiving plate 1324 and a switch 1325, the connecting plate 1321 is fixedly arranged on the bottom plate 12, the cylinder 1322 is fixedly arranged on the top of the connecting plate 1321, and the undulating rod 1323 is fixedly arranged on the cylinder 13 22 is slidably arranged inside and extends out of the cylinder 1322, a reset spring is fixedly arranged between the cylinder 1322 and the ups and downs rod 1323, the inner bottom wall of the cylinder 1322 is fixedly arranged with the switch 1325, and the receiving plate 1324 is fixedly arranged with the top of the ups and downs rod 1323 and is located at the bottom of the detection; the suction cup 1313 can increase the connection and fixation between the base 1 and the bottom plate 12, and at the same time, when the base 1 and the top device shake, the detection plate 1314 will shake synchronously, and the shaking of the detection plate 1314 will squeeze the receiving plate 1324, so that the ups and downs rod 1323 at the bottom of the receiving plate 1324 will fluctuate up and down inside the cylinder 1322, and the ups and downs that do not touch the switch 1325 do not need to be repaired. When repeated shaking left and right causes the switch 1325 to intermittently receive signals, it indicates that the device is in a dangerous period of shaking and needs to be repaired. When the switch 1325 has been receiving signals, it indicates that the device has been tilted to one end for a long time.

[0035] Secondly, the protection mechanism 14 includes a partition plate 141, an extended sway reduction plate 142 and a locking assembly 143. The partition plates 141 are provided in plurality and are fixed to the bottom wall of the base 1. Both side walls of the base 1 are provided with card slots. The extended sway reduction plate 142 extends through the card slots to the inside of the base 1. A plurality of return springs are fixed between the partition plate 141 and the extended sway reduction plate 142. The locking assembly 143 is provided in two groups and is symmetrically arranged in the base 1 to limit the position of the extended sway reduction plate 142. Preferably, the locking assembly 143 includes a motor 1431, a support plate 1432, a threaded rod 1433, a sliding rod 1434, a first ring 1435, a second ring 1436, a connecting rod 1437 and a locking C-shaped rod 1438.

[0036] When the switch 1325 keeps receiving signals, it indicates that the device has been tilted to one end for a long time. At this time, the locking assembly 143 is started, and the motor 1431 is started to drive the threaded rod 1433 to rotate, so that the first ring 1435 and the second ring 1436 move on the threaded rod 1433 and the sliding rod 1434 respectively, driving the locking C-shaped rod 1438 to move out of the extended sway reduction plate 142. After the lock is released, under the compression of the reset spring, the two extended sway reduction plates 142 pop out of the card slot, expanding the friction area between the two sides of the base 1 and the ground, which can reduce shaking and floating after falling.
