Abstract
The invention relates to a gate auto-locking device for large-sized hydropower stations or pumped storage power stations. The gate auto-locking device comprises a locking bar, a counterweight, a shaft, a shaft sleeve, and a locking support. The locking bar and the counterweight are fixed on the shaft sleeve. The shaft sleeve sleeves the shaft. The shaft is fixed on a concrete foundation through the locking base. A gate is provided with a locking slot matching with the gate auto-locking device; the locking slot is provided with a locking point at which the gate is locked and a free position at which the gate is unlocked.
Description
Technical field
The present invention relates to the locking device of large hydropower station or pumped storage power plant self-action gate.
Background technology
Large-scale or heavy gate in actual motion, the inactive state of normal time in opening.For unsettled gate, though there is brake control, when brake troubles, gate can be out of control, freely glides; In addition, gate is unsettled has long-time load to wire rope, has increased the fatigue strength of wire rope, is more than serious potential safety hazard.In order to ensure gate safe operation, need locking device is installed, in the time that not opening and closing, gate locks.
Summary of the invention
For addressing the above problem, the invention provides a kind of automatic valve locking device, can ensure gate safe handling.
Concrete solution is: a kind of automatic valve locking device, it is characterized in that, comprise securing rod, balancing weight, axle, axle sleeve and locking bearing, described securing rod and balancing weight are fixed on axle sleeve, described axle sleeve is sheathed on axle, axle is fixed in concrete foundation by locking base, and gate locating has the lock slots matching with locking device, the freely position of using when keyed end when described lock slots is provided with gate lock and gate release.
Further, described locking device is positioned at gate bilateral symmetry to be arranged, is respectively arranged with the lock slots corresponding with locking device on gate.
Further, described locking bearing is fixedly connected with concrete foundation by pre-embedded bolt.
Further, described securing rod becomes 150 ° of angles with balancing weight.
Further, described concrete foundation is provided with the counterweight groove arbitrarily swinging for balancing weight.
Beneficial effect: the present invention does not need manual operation, has avoided the danger of manual work, can accurately carry out again gate lock operation simultaneously; Novel structure, reasonable in design, operating gate is flexible, the locking of large hydropower station or pumped storage power plant self-action gate.
Brief description of the drawings
Fig. 1 is automatic valve locking device lock-out state schematic diagram;
Fig. 2 is automatic valve locking device free state schematic diagram;
In figure, 1-securing rod; 2-balancing weight; 3-axle; 4-axle sleeve; 5-locks bearing; 6-concrete foundation; 7-gate; 8-lock slots; 81-locking bit; 82 free positions-; 9-counterweight groove.
Detailed description of the invention
In the time that gate need to lock, gate is mentioned by headstock gear, now lock in free state, in gate uphill process, drive securing rod to sway, in the time that the keyed end place of gate rises to higher than securing rod top, securing rod is because antimeric gravitational moment is substantially equal, securing rod swings back between keyed end and free position, now gate falls, and securing rod can hold out against in keyed end place, by gate lock.
In the time that gate needs release to transfer, can first gate be mentioned (being greater than 200mm), until freely position, position higher than securing rod top, under Action of Gravity Field, the securing rod rotation that can affranchise, at this moment gate can free releasing, this is gate releasing process.
