So as to fulfill the opening and closing of manhole cover, structure is simple and easy to implement.
（2）The utility model is easy to operate, easy to control, i.e. controllable by the two groups of motor start switch set outside shell
Clockwise or counterclockwise, so as to fulfill being turned on and off for manhole cover, one group of motor start switch starts rotating bar, turns
Lever can drive one group of unilateral bearing to lock and rotate along clockwise/counterclockwise rotation, and another group of unilateral bearing is freely rotated, from
And it realizes manhole cover and is rotated along clockwise/counterclockwise direction；When starting another group of motor start switch, controlling rotary bar is reversed
It rotates, the rotation situation of two groups of unilateral bearings is on the contrary, realize the reverse rotation of manhole cover.
