The working principle of the invention is as follows: when the suspension device for the safety fence of the high-voltage distribution room of the transformer substation is used, the warning board 1 and the safety fence can be installed and fixed firstly, the rotating rod 502 is driven to rotate clockwise by the rotating shaft 503, meanwhile, the rotating shaft 503 can drive the rotating fixture block 5031 to rotate along the arc-shaped rotating groove 5041 in the transmission gear 504, and at the moment, the transmission gear 504 is in a non-rotating state temporarily.

In the process, the rotating rod 502 can drive the transverse moving rod 508 to move towards the rotating rod 502 through the transmission rod 507, and when the rotating fixture block 5031 rotates to contact with the other end face of the arc-shaped rotating groove 5041, the transverse moving rod 508 is separated from the inserting hole 5011 on the moving seat 501; then, the rotating shaft 503 is continuously rotated, at this time, the rotating shaft 503 can synchronously drive the rotating rod 502 and the transmission gear 504 to rotate, the rotating rod 502 drives the transverse moving rod 508 to continuously move, the transmission gear 504 can push the two moving seats 501 to move away from each other through the matching of the two transmission racks 506, and the second reset torsion spring 509 is twisted and deformed during the rotation process of the rotating shaft 503.

When the distance between the two movable seats 501 is larger than the distance between the two vertical rods on the safety fence, the fixed seat 4 is close to the installation position on the safety fence, and when the arc-edge telescopic blocks 511 on the two movable seats 501 are respectively located at the ends, far away from each other, of the two vertical rods, the rotating shaft 503 can be loosened; at this moment, the second reset torsion spring 509 resets to drive the rotating rod 502 to rotate counterclockwise for resetting, the rotating rod 502 can drive the two moving seats 501 to approach each other through the transmission of the rotating shaft 503, the transmission gear 504 and the transmission rack 506, when the arc edge telescopic block 511 on the moving seat 501 contacts with the vertical rod, the arc edge telescopic block 511 is stressed to contract into the moving seat 501, and then the vertical rod can be clamped with the L-shaped fixing block 510.

Flexible piece 511 in arc limit loses the extrusion of montant can automatic re-setting, be about to the montant card at the intermediate position of flexible piece 511 in arc limit and L type fixed block 510, can realize removing the connection of seat 501 with the montant, when the completion removed seat 501 and montant connection, dwang 502 drives horizontal shifting rod 508 in step and inserts inside the spliced eye 5011 on removing seat 501, thereby can make the flexible piece 511 in arc limit that is connected with movable block 513 unable shrink, thereby realize removing seat 501 and the locking of being connected of montant, accomplish warning sign 1's installation this moment.

When needs are dismantled warning sign 1, only need clockwise once more rotate above-mentioned axis of rotation 503 can, because the both ends of the flexible piece 511 in arc limit are the arc limit, consequently when two removal seats 501 separate, its flexible piece 511 in arc limit receives the montant extrusion also can contract to removing inside the seat 501 to the quick dismantlement operation of warning sign 1 of being convenient for.

When different operations are performed by a worker, the corresponding warning slogan needs to be adjusted, at this time, the docking post 306 can be inserted into the docking seat 305 first, and when the lock post 3061 contacts with the lock hole 3021, the docking post 306 is continuously pushed, so that the lock is completely inserted into the lock hole 3021. In the process, the docking post 306 contacts with the lifting block 3072 and presses the lifting block 3072 to move downwards, the lifting block 3072 drives the locking fixture block 307 to move downwards through the lifting rod 3071 and presses the first telescopic spring 308 to contract, and finally the locking fixture block 307 is separated from the rotating gear ring 304, namely the locking of the rotating gear ring 304 is released.

The butt joint post 306 is rotated to drive the rotation axis 302, the rotation ring 304 and the slogan adjusting post 301 to rotate, the switching of the warning slogan can be realized through the rotation of the slogan adjusting post 301, the first reset torsion spring 303 can be stressed and twisted in the process, and the butt joint post 306 can be taken out from the inside of the butt joint seat 305 after the switching of the warning slogan is completed. In this process, the butt joint column 306 releases the extrusion on the lifting block 3072, at this time, the first extension spring 308 resets to push the lifting steel, the lifting block 3072 and the locking fixture block 307 to move upwards, the locking fixture block 307 can be clamped with the tooth groove at the bottom end of the rotating toothed ring 304, namely, the rotating toothed ring 304 cannot rotate at this time, and therefore the rotation angle locking of the slogan adjusting column 301 is achieved.

After the maintenance operation is completed, the worker may reset the slogan adjusting post 301 to the slogan in the initial state, insert the docking post 306 into the docking cradle 305 again, and then release the clamping force applied to the docking post 306. Because the locking fixture block 307 has released the locking of the rotating toothed ring 304 at this moment, and the docking post 306 is not clamped by external force, therefore the first reset torsion spring 303 can automatically reset to drive the rotating shaft 302 and the slogan adjusting post 301 to reversely rotate and reset, finally the slogan adjusting post 301 resets to the initial state, and at this moment, the docking post 306 is taken out, so that the operation is simple and convenient.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
