Background technique
Submersible pump is the visual plant of deep-well water lift.The work that pulls the plug of whole unit is extracted the face of land to underground water during use.Of many uses: as to be applicable to speedily carry out rescue work in domestic water, mine, industrial cooling, field irrigation, seawater promote, steamer is transferred and carried etc.When submersible pump when drawing water, the water level in pond can slowly be lower than the working water level of submersible pump, submersible pump is found time, at this moment the impeller of submersible pump, rotor, bearing, main shaft etc., can not get the heat radiation of water and lubricated, under the running up of motor, cooling medium is overheated to be burnt because of losing very easily to cause submersible pump, while is consumed power also, is unfavorable for energy conservation.
The tradition submersible pump in time has a power failure when finding time for solving, and dual mode is generally arranged:
One is installed a switch in that submersible pump is outside, and as the FK among Fig. 1, switch is the heavy hammer type mechanical switch, utilizes the buoyancy of water effect, makes weight move the control contact-making switch with the lifting of water level and opens and closes, and reaches the effect of finding time of preventing.
The defective of this scheme is, because switch is a mechanical switch, the hard contact of the inside burns easily, burns to death, prevention lost efficacy, and be external, and the part occasion can't be used;
Its two, independently install an electronics level control switch for water additional, as having adopted the electronics level control switch for water among Fig. 2.
Though this mode has been improved the shortcoming of switch, be to use difficulty is installed, control submersible pump water level precision is inaccurate, also inconvenient and the mobile use of submersible pump in zones of different, majority is installed in fixedly that the place opens and closes control.
From as can be known above, now be badly in need of a kind of accurate, simple in structure, easy for installation, safe submersible pump to water level monitoring.
Summary of the invention
For addressing the above problem, the utility model provides a kind of accurate to water level monitoring, simple in structure, easy for installation, safe submersible pump.
The technical solution of the utility model is: a kind of submersible pump that has anti-evacuator, comprise the pump housing, and transformer, motor and water intake is characterized in that: also comprise control circuit, sealing capsule, two water-level detecting probes that place on the lowest water level line; Described control circuit places in the described sealing capsule and by described transformer and links to each other with described motor, and described sealing capsule is fixed on the inside top of the described pump housing; Described control circuit comprises first electrode, second electrode, first resistance, second resistance, triode, relay, diode, electric capacity, described control circuit are connected on the secondary winding of described transformer, and described first electrode is connected on the positive pole of described control circuit by the lead and first resistance, described second electrode connects the base stage of described triode through second resistance by lead, described relay is connected between the collector electrode of first resistance and described triode, and the described diode of cross-over connection on the described relay, described electric capacity are connected across between described first resistance and the described control circuit negative pole; Described water-level detecting probe by insulated conductor respectively with described first electrode, second electrode links to each other.
Described water-level detecting probe is the soft insulated copper wire of 1.5 square millimeters of sub-threads.
The utility model is by the water-level detecting probe that places on the lowest water level line, utilize the electric action monitoring submersible pump working water level of water, by placing the water-level detecting probe on the lowest water level line to link to each other with described control circuit, electric action by water, by described water-level detecting probe in detecting to water level, and carry out switch by control circuit and control, thereby realize the submersible pump vaccuum phenomenon is controlled in real time, reach the submersible motor burnout failure of avoiding submersible pump can not in time have a power failure and cause because of finding time.

Embodiment
In conjunction with the accompanying drawings 1,2,3,4, a kind of submersible pump that has anti-evacuator that the utility model is provided is elaborated.
A kind of submersible pump that has anti-evacuator comprises the pump housing 2, and transformer B, motor 4 and water intake 3 is characterized in that: also comprise control circuit 7, sealing capsule 1, two water-level detecting probe A1, A2 that place on the lowest water level line; Described control circuit 7 places in the described sealing capsule 1 and by transformer B and links to each other with motor 4, and described sealing capsule 1 is fixed on the inside top of the described pump housing 2; Described control circuit 7 comprises first electrode 5, second electrode 6, first resistance R 1, second resistance R 2, triode T, relay J, diode D, capacitor C, described control circuit 7 is connected on the secondary winding of described transformer B, and described first electrode 4 is connected on the positive pole of described control circuit 7 by the lead and first resistance R 1, described second electrode 6 connects the base stage of described triode T through second resistance R 2 by lead, described relay J is connected between the collector electrode of first resistance R 1 and described triode T, the described diode D of cross-over connection on the described relay J, and described capacitor C is connected across between described first resistance R 1 and described control circuit 7 negative poles; Described water-level detecting probe A1, A2 link to each other with described first electrode, 5, the second electrodes 6 respectively by insulated conductor.
