Abstract
The utility model relates to a water level alarming device. A floating ball is put in a grape ditch, when the ditch is full of water, the switch of the floating ball is turned off, the coil of a relay is electrified, a normally open switch of the relay is turned off, direct-current power supply supplies power for a light-emitting diode through a current-limiting resistor, the light-emitting diode emits light and gives an alarm after being electrified, thus helping a night guard manage the irrigation of a vineyard. One person can manage the irrigation of a large area of the vineyard easily, and the light-emitting diode can also be used for lighting, and has little power consumption, thus improving the safety of night work.
Description
Technical field
The utility model relates to a kind of device, particularly a kind of water-level alarm device.
Background technology
Still by artificial, particularly evening, a people waits for whole vineyard in the pouring of the grape trellis in present many places, causes watering to such an extent that water overfills through regular meeting because of sleeping or carelessness.
Summary of the invention
The utility model is at watering the unmanageable problem of grape night, propose a kind of water-level alarm device, can help the people to control the irrigation in whole vineyard night easily, being difficult for makeing mistakes.
The technical solution of the utility model is: a kind of water-level alarm device, comprise float switch, relay, resistance, light emitting diode and direct supply, float switch and with the positive and negative two ends that connect direct supply after relay coil is connected, the normal open switch of relay and the positive and negative two ends that connect direct supply after resistance, light emitting diode are connected.
The beneficial effects of the utility model are: the utility model water-level alarm device, and the irrigation in help Admin Administration vineyard at night, a people can manage the irrigation in large stretch of vineyard easily, has improved security.
Description of drawings
Fig. 1 is the utility model water-level alarm device control principle figure.
Embodiment
Schematic diagram as shown in Figure 1, the water-level alarm device comprises float switch 2, relay 3, resistance 5, light emitting diode 6 and direct supply 1, float switch 2 and with the positive and negative two ends that connect direct supply 1 after relay 3 coils are connected, the normal open switch 4 of relay 3 and the positive and negative two ends that connect direct supply 1 after resistance 5, light emitting diode 6 are connected.
Ball float is placed in the grape ditch, when water is full, float switch 2 closures, relay 3 coils get electric, normal open switch 4 closures of relay 3, and direct supply 1 gives light emitting diode 6 power supplies by current-limiting resistance 5, light emitting diode 6 gets electroluminescence and reports to the police, the keeper sees that light just knows that the water in this grape ditch is full, can turn off water valve, stops to irrigate.The light emitting diode power saving can be thrown light on again, improves the security of working at night.
Claims (1)
