Description
Technical field
This utility model is related to the circuit structure for automatic drain system.
Background technology
Automatic drain system is widely used in the production and construction such as industrial undertaking, municipal public use, civilian.To tunnel, culvert,
The problems such as percolating water of the building structure such as hydrops well, pond, hydrops draining, carries out real-time detection and process.It effectively can reduce
The labor intensity of operating personnel, solves the staff manual detection problems such as not in time.
Automatic drain system is susceptible to detect the failures such as failure, ground connection failure, short circuit in operation, so which is automatic
Drain function fails.If personnel can not inspection in time process, it is also possible to the production run of entail dangers to equipment and personal safety.
There is problems with current automatic drain system：
1st, the easy leak of its ball float of floating-ball level switch formula device, ball float position easily offset, magnetic reed switch service life
It is short, it is easily damaged.
2nd, its liquidometer and physical contact between media of magnetic float type, floater seal have to strictly, otherwise can not
Normal work.And the problems such as magnetic material has demagnetization, it is easily caused liquidometer cisco unity malfunction.
3rd, the liquidometer turnover panel of magnetic flap (post) formula device is easily stuck, and causing cannot teletransmission instruction.Magnetic material is such as
There are the phenomenons such as demagnetization to also result in liquidometer cisco unity malfunction.
4th, its expensive, ginseng that instrument needs are arranged of the device of electromagnetic radar liquidometer (guide wave radar liquid level gauge) formula
Number is more, once go wrong, it is generally difficult to it is that what reason is caused to find.If antenna itself is stained with medium accidentally also can
Report an error.
5th, ultrasonic level gage ratio of precision is relatively low, and test easily has blind area.
6th, static pressure (differential pressure) formula liquidometer is affected very big by Media density and temperature, so usually ratio of precision is poor, and is
These impacts are eliminated, a lot of other test instrumentations is needed, is finally built a set of perfect static pressure measurement system price cost very high.
7th, the pipe of protecting and leading that the float of magnetostriction type liquidometer can be outside waveguide is moved up and down, and is stuck sometimes, and
And its metering system and installation, maintenance requirement are all higher.
Utility model content
This utility model provides a kind of circuit structure for automatic drain system, with accurately and reliably sensed water level,
And low cost, stable performance.
This utility model is used for the circuit structure of automatic drain system, including：It is connected with liquid level relay by water pump
Chopper, liquid level relay are connected to level electrode by wire, and wire is provided with metal with the connection end of level electrode and visually passes
Lead probe.The circuit structure can be located in the electric control box at scene, wherein mounting means of the level electrode in catch pit
May refer to GB99SD767 standards.After water level rises to the specified location of level electrode, liquid level relay is connected by wire
Device, liquid level relay of the water pump by channel status, draws water being powered by chopper.When water level is down to specifying for level electrode
Behind position, liquid level relay is made to form open circuit by wire, water pump stops pumping.Circuit structure of the present utility model is simply real
With going in the building structure of the easily hydrops such as various tunnels, culvert, hydrops well, pond.
Further, if the contact capacity of liquid level relay is single-phase below 5A, can be direct by liquid level relay
Control water pump, if its contact capacity is the three phase mains circuit higher than 5A, needs between liquid level relay and chopper
Auxiliary reclay is connected with, water pump is connected to auxiliary reclay, water pump is controlled after liquid level relay starts auxiliary reclay.
Preferably, liquid level relay is connected at the different liquid levels of level electrode by least 3 wires, is easy to point
Distinguish and control different water level conditions.The height of bottom wire can be common wire height, and the height of the top wire is to take out
Water height, after water level rose this height, connects pumping for water pump by corresponding wire, and the height of central conductor is taken out for stopping
Water height, when water level low mistake height, makes water pump stop pumping by corresponding wire.The height of the top wire and centre
The height of wire can be determined by skilled addressee.
Further, the visual conductive probes of described metal are the threaded fastener fixed with wire.Threaded fastener can
To be bolt-nut structure, bolt be connected with wire after by nut screwing clamping, be difficult from wire dropping.By threaded fastener
Conductive probes can clearly observe the residing height of water level of probe, be conveniently adjusted distance, control region of drawing water.And this mode
Conductive probes Maintenance and Repair it is convenient, it is with low cost.
Further, the input connection 220V external power supplys of the chopper, are that water pump is powered.
The circuit structure of automatic drain system of the present utility model, can accurately and reliably sensed water level, and structure and
Install simple, low cost, stable and reliable for performance, Maintenance and Repair are convenient, effectively can exclude automatically flood and reduce cost of labor.
Specific embodiment with reference to embodiments, remakes to the above of the present utility model further specifically
It is bright.But this scope for being interpreted as the above-mentioned theme of this utility model should not be only limitted to Examples below.New without departing from this practicality
In the case of the above-mentioned technological thought of type, the various replacements made according to ordinary skill knowledge and customary means or change,
Should be included in the range of this utility model.
