Abstract

The invention discloses a water level detection control alarm, which comprises a circuit breaker, wherein an input end of the circuit breaker is connected with a live wire and a null line of a power supply; an output end of the circuit breaker is connected to a high-voltage side of a transformer; a low-voltage side of the transformer is connected with an input end of a bridge rectifying circuit; a first output end of the bridge rectifying circuit is connected with a first end of a capacitor C1, a first end of a resistor R1, a first end of a resistor R3, an emitter of a transistor Q2, a negative electrode of a diode VD and a first end of a relay JL; and a second output end of the bridge rectifying circuit is connected with a second end of the capacitor C1, a second end of the resistor R1, a second end of a resistor R2, a second end of a capacitor C2, an emitter of a transistor Q1, an emitter of a transistor Q4 and an emitter of a transistor Q3. The water level detection control alarm realizes the functions of automatic control of motor operation and water level alarm, greatly reduces manpower, and improves the reliability of electricity utilization.

Description

technical field [0001] The invention relates to the field of water level detection, in particular to a water level detection control alarm. Background technique [0002] With the continuous improvement of people's living standards, most customers install water storage tanks on the roof as water sources for various water areas in the courtyard. When I went to the customer's home to report for repairs, I found that most customers often forgot to turn off the water source switch in time when the water storage tank installed on the roof filled the water level, causing the water storage tank to overflow, which made the power line in the home safe and stable. The operation brings potential safety hazards. If the insulation package of the joints of the lines is not tight, the lines will be short-circuited when exposed to water, causing the switch of the meter box to trip and cut off the power. In severe cases, it may even cause a fire. Contents of the invention [0003] In order...
