Abstract
The utility model provides a water level alarm device for watercrafts. The utility model is provided with a water level sensor, an alarm element and a relay, wherein an electromagnet coil of the relay is connected in series with the contact of the water level sensor and then the electromagnet coil and a power supply form a loop; the normally closed contact of the relay is connected in series with the alarm element and then the normally closed contact and the power supply form a loop. The contact of the water level sensor is designed as a normally closed contact when used for alarm of water intake of a bilge; when the water level of the bilge exceeds the maximum water level, a moving contact piece is supported so that the normally closed contact is disconnected so that the electromagnet coil of the relay loses electricity and the alarm element works. The contact of the water level sensor is used as a normally open contact when designed for alarm of water shortage of a fish hold; when the water level of the fish hold is lower than the lowest water level, a push rod is naturally sagged so that the normally open contact is reset so that the electromagnet coil of the relay loses electricity and the alarm element works. The working mode makes control staffs know whether the circuit of the water level sensor is disconnected and fails without check so as to prevent accidents because the sensor can not send out signals to the alarm circuit in time.
