Electronic unlocking piece is used for the control sensor, and after the sensor was activated by electronic unlocking piece, whole circuit switched on, and the circular telegram of electromagnetism piece produced magnetic force, and magnetic force and metal kicking block repel each other and promote the metal kicking block, and the metal kicking block upwards shifts and then promotes the fore-set along the slide rail, because fore-set and wedge integrated into one piece, the wedge breaks away from with the latch hook, and then the well lid can continue to reach the purpose of opening the well lid completely by hydraulic stem jack-up. The metal top block is a hemispherical top block, and the top column is a top column with a hemispherical tail end. The design of hemisphere kicking block and hemisphere fore-set makes mutual direct contact more level and smooth, makes the demand of the magnetic force that the electromagnetism piece produced lower.
Example 3:
the embodiment (see fig. 5) is substantially the same as embodiments 1 and 2, except that in this embodiment, the locking member includes a connecting seat, an upper wedge 281A and a lower wedge 281B fixed on a side wall of the cable well, the connecting seat is provided with a movable cavity, the upper wedge and the lower wedge are connected with each other and integrally form a C shape, an inclined plane of the upper wedge faces upward toward a center side of the well lid body, an inclined plane of the lower wedge faces downward toward a center of the cable well, a length of the lower wedge is longer than that of the upper wedge, the upper wedge and the lower wedge are both installed in the movable cavity of the connecting seat, a return spring for controlling the upper wedge and the lower wedge to stretch is arranged in the movable cavity, an upper end of the hydraulic rod is aligned with a lower end face of the lower wedge, and the locking hook is located between the upper wedge and the lower wedge, an electromagnetic block is fixed on the side wall of the movable cavity close to the cable well and connected with a weak current power supply. Thereby the position of wedge piece under the last wedge piece is pulled to realize the unblock through the mode that the electromagnetism piece got electric actuation in this embodiment, simultaneously, because the self characteristics of hydraulic stem can directly push away lower wedge piece to drive the last wedge piece, realize the direct unblock of hydraulic means action.
The above-described embodiments are only preferred embodiments of the present invention, and are not intended to limit the present invention in any way, and other variations and modifications may be made without departing from the spirit of the invention as set forth in the claims.
