Detailed Description
A sewer sewage backflow alarm device comprises an induction pipe and an alarm generator, wherein the axial cross section of the induction pipe is L-shaped, and a floater 1 is movably arranged in the induction pipe.
As shown in figure 1, the opening of the horizontal section 2 in the induction pipe is connected with the branch pipe of a sewer (a left thick pipe in the figure) through a standard interface, and the alarm generator is arranged on the opening of the vertical section 3 in the induction pipe. The inner wall of the upper part of the induction pipe vertical section 3 is provided with an annular bulge 4, and an ejection block 5 is movably arranged on the annular bulge 4.
The floater 1 is positioned in the vertical section 3 of the induction pipe and can move up and down in the vertical section 3. The floater 1 is a step cylinder, the diameter of the lower cylinder is smaller than the diameter of the inner wall of the vertical section 3 and larger than the inner diameter of the annular bulge 4, so that the floater can freely lift and is not inclined and clamped; the diameter of the upper cylinder is smaller than the inner diameter of the annular bulge 4, and the floater 1 can still pass through the inner circle of the annular bulge 4 when the lower cylinder touches the inner wall of the vertical section 3.
The ejection block 5 comprises a circular flat plate and an ejector rod positioned on the flat plate, one end of the ejector rod is fixed on the flat plate, and the other end of the ejector rod is fixedly provided with a magnetic steel 6. The ejector rod of the ejection block 5 extends into the bottom of the box body 7 of the alarm generator, and the magnetic steel 6 is positioned in the alarm generator.
3 lateral walls of vertical section of induction pipe have connect blow off pipe 8, and the opening part of blow off pipe 8 is equipped with can open apron 9, blocks dust and debris entering at ordinary times, opens when sewage backward flow and emits sewage.
As shown in fig. 2, the alarm generator includes a box 7, a battery 10, a reed switch 11, and a current limiting resistor 12 are disposed in the box 7, a light emitting diode 13 and a buzzer 14 are disposed on the box 7, and the reed switch 11 corresponds to the magnetic steel 6.
The positive pole of the battery 10 is connected with one end of the reed switch 11, and the negative pole of the battery 10 is connected with the negative pole of the light emitting diode 13 and one pin of the buzzer 14. The other end of the reed switch 11 is connected to the anode of the light emitting diode 13 and is connected to the other pin of the buzzer 14 through the current limiting resistor 12.
When the sewer normally drains, sewage is directly discharged downwards from a main pipe of the sewer. When the sewage flows back, the sewage flows into the branch pipes of the sewage, and the float 1 is raised. When the floater 1 rises to a certain degree, the upper cylinder of the floater penetrates through the annular bulge 4 to push the ejection block 5 upwards, and therefore the magnetic steel 6 is close to the magnetic control switch 11 of the reed switch, so that the internal electrode of the reed switch is attracted, the circuit is connected, the light emitting diode 13 and the buzzer 14 are started, and audible and visual alarm is carried out. The battery 10 is a 12V dry battery, the light-emitting diode 13 is an automatic flashing light-emitting LED, the buzzer 14 is a 12V direct current-driven micro buzzer, and the resistance value and the rated power of the current-limiting resistor 12 are determined according to the working current and the working voltage of the LED. In order to enable the light emitted by the alarm device to be observed in multiple directions during operation, a plurality of automatic flashing LEDs can be connected in series-parallel connection.
