Utility model content
The purpose of this utility model is the device providing a kind of elevator pit ponding automatic pumping and safety control for the deficiencies in the prior art, automatic pumping process can be carried out to elevator pit ponding, effectively can lower damage and the corrosion of lift facility, reduce the personal injury to passenger.
For achieving the above object, the utility model adopts following technical scheme:
A device for elevator pit ponding automatic pumping and safety control, when elevator pit ponding exceedes predetermined controlling water level, float-type switch triggering mechanism starts the water pump be positioned over bottom elevator pit and starts to draw water; When pumping for water pump is not enough to balance the speed that extraneous water enters pit, when ponding arrives predetermined safety control water level, float-type switch triggering mechanism starts elevator controlling switch, calls the program be preset in elevator controlling chip, elevator is stopped to designated floor, close elevator when unmanned state.
Described predetermined controlling water level, refers to the consideration according to elevator design, and a controlling water level of the design such as the consideration of environment for use and safe handling, this water level can as requested and elevator model size adjustment.
Described predetermined safety control water level, the speed that extraneous water flows into elevator pit exceedes pumping drainage speed, will continue to rise on the basis of predetermined controlling water level, elevator runs after a certain water level will affect its service life or safety, and predetermined safety control water level just refers to and on the basis of this water level, adds design capacity and the controlling water level designed.
A kind of elevator pit ponding automatic pumping of the utility model design and safety control, comprise water pump, water pump master cock, elevator controlling switch, float-type switch triggering mechanism.
The utility model beneficial effect is:
A kind of device for detecting water level of elevator bottom pit described in the utility model and check processing device thereof, effectively can lower damage and the corrosion of lift facility, reduce the personal injury to passenger.Existing elevator pit is mostly low than building bottom, often pit ponding occurs, and causes elevator device failure or corrosion, electric elements lost efficacy, even can cause passenger's personal injury etc. time serious.The utility model device can when elevator pit ponding Auto-drainage and emergent stopping elevator.

Detailed description of the invention
A kind of elevator pit ponding automatic pumping and safety control, it is characterized in that: when pumping for water pump is not enough to balance the speed that extraneous water enters pit, when ponding arrives predetermined safety control water level, float-type switch triggering mechanism starts elevator controlling switch, call the program be preset in elevator controlling chip, elevator is stopped to designated floor, close elevator when unmanned state.
Preferably, elevator pit ponding automatic pumping and safety control comprise that float-type switch triggering mechanism comprises adapter plate 1, water pump master cock adapter plate 2, water pump master cock 3, water pump master cock hit plate 4, thread-forming screw 5, elevator controlling switch 6, switch re-pack 7, floating block 8;
Preferably, water pump 11 is arranged on elevator pit by water pump seat board 10, and float-type switch triggering mechanism 9 is arranged on the elevator shaft wall 12 of pit.
Preferably, during work, be fixed on that the water pump master cock switch hit on plate 4 re-packs 7, thread-forming screw 7 amasss buoyancy of water by pit and holds up upper and lower displacement in the guide groove of adapter plate 1 together with floating block 8.When pit does not have ponding or ponding is little, water pump master cock is hit plate 4 and is limited on adapter plate 1 in extreme lower position by thread-forming screw 5, and now, water pump master cock 3 is in closed condition, and water pump 11 is shut down; When pit ponding arrives predetermined controlling water level, water pump master cock is hit plate 4 and can be touched water pump master cock 3, starts water pump 11 and works and extract pit ponding out; When pumping for water pump is not enough to balance the speed that extraneous water enters pit, when ponding arrives predetermined safety control water level, switch re-packs and 7 can touch elevator controlling switch 6, elevator is accessed by thread switching control 13, call the program be preset in elevator controlling chip, elevator is stopped to designated floor, close elevator when unmanned state.
Preferably, water pump master cock adopts micro-switch;
Preferably, the quantity of thread-forming screw 7 is 1;
Preferably, the quantity of thread-forming screw 7 is 2;
Preferably, 100mm is designed to by the adjustable predetermined controlling water level in installation site;
Preferably, 300mm is set to by the predetermined safety control water level of installation site and the adjustment of water pump master cock dress plate cut to lengthen.
