Background technology
Water tower is the capital equipment that supplies water to vast small towns, urban residents, and the normal operation method is: the water in the water tank of water tower is finished, and after water pipe flowed not water outlet, the employment pump motor of fetching boiling water was fetched water in the water tank of water tower.See or hear that the water spill-over in the water tank of water tower goes out that the motor that switches off the pump again stops to supply water.This method will someone operate.The water that the water spill-over goes out slatterns.
Summary of the invention
The purpose of this utility model provides a kind of automatic water supply device, can be in the water tank of water tower waterborne be raised to need the position in, make electric water pump stop to supply water.When dropping to bottom time under water in the water tank of water tower, water pump just can water supply start.
The purpose of this utility model realizes as follows: connect the coil of contactor when the performance of utilizing water to conduct electricity, waterborne in the water tank of water tower are raised to and need the position, make the normally closed interlock outage of contactor, pump motor stops.Drop to the bottom under water in the water tank of water tower, disconnect the coil of contactor, make the normally closed interlock energising of contactor, pump motor is opened beginning to the cistern water supply of water tower.
Water inlet control bottom electrode and water inlet control top electrode are contained in the bottom of the water tank of water tower, the control bottom electrode of cutting off the water is controlled the liquid level place that top electrode is contained in the water tank needs of water tower with cutting off the water, water inlet control bottom electrode is connected with contactor coil one end, the other end of contactor coil is connected with an end of transformer output winding, the other end of transformer output winding is connected with the control top electrode of cutting off the water, the control bottom electrode of cutting off the water is connected with water inlet control top electrode, normally open contact of contactor connects cut off the water control bottom electrode and the control top electrode of cutting off the water, the two ends of transformer input coil are connected on respectively on the power line, power line is introduced by fuse, pump motor is connected with power line by the normally closed interlock of contactor, water inlet control bottom electrode, water inlet control top electrode, the control bottom electrode of cutting off the water is welded with a small amount of argent with the end points of controlling top electrode of cutting off the water.
The advantage of this automatic water supply device is: can make water tower that water is arranged all the time, add the water process implementation and automatically control, save manpower, and water-saving and environmental protection, leveling device is simple in structure, dependable performance.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described.
Accompanying drawing is the structure chart of water tower automatic water supply device.
1. pump motors among the figure, 2. contactor coil, 3. contactor normally closed interlock, 4. water tower, 5. transformer is 6. intake and is controlled bottom electrode, 7. water inlet control top electrode, 8. fuse, 9. power line, the control bottom electrode of 10. cutting off the water, the 11. control top electrodes of cutting off the water, 12. contactor normally open contacts.
The specific embodiment
In the accompanying drawings, electrode adopts the absolutely sub-thread copper core of rubber of normal tape, and at a small amount of argent of copper core end points welding, its effect is to conduct electricity very well, and is anticorrosive.Can increase the application life of automatic water supply device.The installation of electrode generally is the hole of boring a minor diameter in the corresponding installation position of the water tank of water tower, seals with water tight packing behind the threading electrode.Water inlet control bottom electrode (6) and water inlet control top electrode (7) are contained in 50～100 millimeters places, bottom of the water tank of water tower (4), 20～30 millimeters at water inlet control bottom electrode (6) and water inlet control top electrode (7) interval.Cut off the water control bottom electrode (10) and the control top electrode (11) of cutting off the water is contained in the liquid level place of the water tank needs of water tower (4), generally 200～400 millimeters places below the water tank of distance water tower (4) is suitable for reading.Cut off the water control bottom electrode (10) and cut off the water and control 20～30 millimeters at top electrode (11) interval.For safety, adopt the low-voltage contactor, need to pass through transformer (5) to two of the driven line of force (9) introducing to electricity and be depressured to 24 volts, supply with control circuit.Water inlet control bottom electrode (6) is connected with contactor coil (2) one ends, the other end of contactor coil (2) is connected with an end of transformer (5) output winding, the other end of transformer (5) output winding is connected with the control top electrode (11) of cutting off the water, the control bottom electrode (10) of cutting off the water is connected with water inlet control top electrode (7), a normally open contact of contactor (12) connects cut off the water control bottom electrode (10) and the control top electrode (11) of cutting off the water, the two ends of transformer (5) input coil are connected on respectively on the corresponding line of power line (9), power line (9) is introduced by fuse (8), and pump motor (1) is connected with power line by the normally closed interlock (3) of contactor.When the liquid level rising is controlled top electrode (11) above cutting off the water, cut off the water control bottom electrode (10) and control top electrode (11) the connection contactor coil (2) of cutting off the water.Contactor normally open contact (12) adhesive, the normally closed interlock of contactor (3) separates outage, and pump motor (1) stops, and supplies water and finishes.When the water of the water tank of water tower (4) is used up, liquid level is below water inlet control top electrode (7), and water inlet control bottom electrode (6) and water inlet control top electrode (7) disconnect, and contactor separates, the normally closed interlock of contactor (3) is connected, pump motor (1) water supply start.
