Background technology

The light water level control device refers to carry out the control of high-low water level by the mode of mechanical floats formula or electronic type, or utilizes the PLC program to carry out logic by mechanical floats and electronic type bound switching value and judge.Realization reaches control to water level by AC/DC contactor to the on off control of water pump.Or consist of band self-sustaining peripheral control circuit by mechanical floats formula (electronic type) switch and AC/DC contactor auxiliary contact, could realize to pump motor unlatching, stop until controlling the purpose of water level.

Summary of the invention

For solving the problems of the technologies described above, the utility model provides a kind of automatic level controller, can realize the Automatic Control of water level, need not peripheral circuit lower limit water level, ordinary water level, upper limit water level, upper limit water level are detected and logic analysis.

Above-mentioned purpose of the present utility model is to realize by such technical scheme: automatic level controller, comprise transformer, the full-bridge rectification module, transformer connects the full-bridge rectification module, the full-bridge rectification module connects first detection module, first detection module connects the second detection module, and the second detection module connects the 3rd detection module.

First detection module is provided with the first water level detecting point, the second water level detecting point, and the second detection module is provided with the 3rd water level detecting point, and the 3rd detection module is provided with the 4th water level detecting point.

Described first detection module comprises the first relay, and first detection module connects the second detection module, the 3rd detection module by the contact of the first relay.

Described the first water level detecting point, the second water level detecting point, the 3rd water level detecting point, the 4th water level detecting point position raise successively.

The beneficial effect of a kind of automatic level controller of the utility model is as follows:

1), integrate automatic control and measurement part, exempt loaded down with trivial details that the mechanical floats split arranges, exempt the peripheral control circuit.

2), easy to use, install simple.

3), all can finish easily control to the water level of differing heights, the degree of depth, complex space.

4), according to user's needs fixed test point and motion detection point can be set, layout check point convenience, easy maintenance.

5), the utility model can supply gauge tap amount and alerting signal amount simultaneously, for micro computer monitoring.

Embodiment

As shown in Figure 4, automatic level controller, comprise transformer T0, full-bridge rectification module D1, transformer T0 connects full-bridge rectification module D1, it is characterized in that, full-bridge rectification module D1 connects first detection module 1, first detection module 1 connects the second detection module 2, the second detection modules 2 and connects the 3rd detection module 3.First detection module 1 is provided with the first water level detecting point E1, the second water level detecting point E2, and the second detection module 2 is provided with the 3rd water level detecting point E3, and the 3rd detection module 3 is provided with the 4th water level detecting point E4.Described first detection module 1 comprises the first relay K 1, and first detection module 1 connects the second detection module 2, the 3rd detection module 3 by the contact of the first relay K 1.

Among Fig. 4, triode T1, optocoupler CTR consist of the detection driving circuit, when between the first water level detecting point E1, the second water level detecting point E2 the 1mA electric current being arranged, drive the first relay K 1 charged, the contacting of the first relay K 1, the second detection module 2,3 work of the 3rd detection module.

Simultaneously, optocoupler CTR cooperates the formation anti-jamming circuit with triode T1, avoid causing that because triode T1 is operated in the amplification region the first relay K 1 bounce flash makes reliable in action.

Triode T2 and controllable silicon SCR 1, triode T3 and controllable silicon SCR 2 consist of charged self-hold circuit, when the second detection module 2, when the 3rd detection module 3 has the 1mA electric current, controllable silicon SCR 1, SCR2 conducting, and the second detection module 2, the 3rd detection module 3 loops continue to keep conducting after disconnecting.When water level arrived low-water level, the second water level detecting point E2, the 3rd water level detecting point E3 disconnected.Capacitor C 2 consists of delay circuit with triode T1, as the first water level detecting point E1, when the second water level detecting point E2 is in off state, when making the loop delay working to low-water level, makes the first relay K 1 dead electricity, disconnects relay K 2, K3 loop, realizes termination of pumping.

As shown in Figure 1, described the first water level detecting point E1, the second water level detecting point E2, the 3rd water level detecting point E3, the 4th water level detecting point E4 position raise successively.

The utility model automatic level controller only relies on and self can realize the Automatic Control of water level.Need not peripheral circuit detects and logic analysis lower limit water level, ordinary water level, upper limit water level, upper limit water level (correspondence: the first water level detecting point E1, the second water level detecting point E2, the 3rd water level detecting point E3, the 4th water level detecting point E4).And disconnect with the electronics automatic time delay, the electronics self-retaining function, the user only need supply AC220V power supply, the switching value of utilizing automatic level controller to provide, directly connect the AC/DC contactor coil and realize the automatic start-stop of water pump M1, M2 is controlled, reach the required control water level of user.

When power station sump leakage was normal, the automatic start-stop main pump when leakage or when coming the water yield larger, started standby pump operation automatically, and and alarm.
