Abstract
An automatic water level controller of a fire-fighting impounding reservoir includes a normal close inching switch and an electromagnetic valve, wherein the electromagnetic valve is electrically connected with the normal close inching switch and is arranged on a water supply pipeline, a spring tab is arranged above the normal close inching switch, one end of the spring tab is cocked upwards, the cocked part of the spring tab may be contacted with the normal close inching switch in press, the spring tab is provided with a roller which may roll back and forth on the spring tab, the roller is arranged on a contact arm, and the contact arm is connected with a floater. When the quantity of the water of the impounding reservoir is reduced, the floater may decline along with the water surface so as to contact the switch to alarm and open the electromagnetic valve to supply water, when the water is supplied enough, the floater will rise along with the water surface to disconnected with the switch and automatically stop supplying water.
Description
Technical field
The utility model relates to a kind of fire-fighting cistern water level automatic control device.
Background technology
The transformer of power-plant operation all is equipped with the complete spraying system of fire fighting of a cover.The water source of spraying system of fire fighting comes from the fire-fighting cistern, and how much water is that such monitoring means is unreliable unsafe by eye-observation, manual moisturizing at present in the cistern.
Summary of the invention
For monitoring and the moisturizing robotization that realizes the fire-fighting cistern, so design the utility model.
Design of the present utility model is: thus the water in cistern is cursory after a little while along with the water surface touching switch that descends is reported to the police and the opens solenoid valve moisturizing, stops automatically when water replenishes when enough rise cursory also rise no longer contact-making switch warning and moisturizing of the water surface thereupon.
The utility model comprises normally closed type point driving switch, solenoid valve, solenoid valve is electrically connected with the normally closed type point driving switch, solenoid valve is installed on the moisturizing pipeline, the top that it is characterized in that the normally closed type point driving switch is equipped with spring leaf, and an end of spring leaf is upturned, and this part spring leaf that is upturned can touch the normally closed type point driving switch when depressing, spring leaf is provided with roller, roller can come rollback moving on spring leaf, and roller is installed on the touching arm, touching arm and cursory linking together.
Principle of work of the present utility model is: when water level descends gradually, cursory decline, the touching arm that roller is installed moves downward thereupon, the roller perk position on limit from top to bottom rolls, after making the spring leaf at perk position stressed, press the normally closed type point driving switch, thereby the touching switch is reported to the police and the opens solenoid valve moisturizing.
When water level rises gradually, cursory rising, the touching arm moves upward thereupon, and roller leaves the spring leaf at perk position, and the spring leaf at perk position is no longer stressed, recovers the state of perk, thus no longer contact-making switch is reported to the police and moisturizing stops automatically.
Description of drawings
Fig. 1 is a structural drawing of the present utility model.
Among the figure: 1, bolt, 2, spring leaf, 3, roller, 4, web joint, 5, the touching arm, 6, cursory arm, 7, spacing ring, 8, ball float.
Embodiment
Below in conjunction with embodiment and accompanying drawing thereof, describe embodiment of the present utility model in detail, but embodiment of the present utility model is not limited to following embodiment.
Embodiment one: present embodiment comprises the normally closed type point driving switch, solenoid valve, solenoid valve is electrically connected with the normally closed type point driving switch, solenoid valve is installed on the moisturizing pipeline, spring leaf by bolt be installed in the normally closed type point driving switch be on the conplane body of wall, the top of normally closed type point driving switch is equipped with spring leaf, one end of spring leaf is upturned, this part spring leaf that is upturned can touch the normally closed type point driving switch when depressing, spring leaf is provided with roller, roller can come rollback moving on spring leaf, and roller is installed on the touching arm, and touching arm and cursory arm link together, cursory arm is provided with ball float, in order to prevent the drift of cursory arm, cursory arm is spacing by spacing ring, guarantee that cursory arm is straight on, straight mobile down, spacing ring can be provided with several according to the length of cursory arm, and spacing ring is fixed on the wall of cistern.
Embodiment two: the normally closed type point driving switch of present embodiment is electrically connected with solenoid valve and hummer, and solenoid valve is connected in parallel with hummer and then is connected with the normally closed type point driving switch, and other structure is identical with embodiment one.
