The present utility model provides an embodiment:
as shown in fig. 1, a theft stop alarm circuit of a travelling mechanism of a thickener comprises a normally closed current induction switch, a digital time relay KT, an intermediate relay KA, a travelling mechanism motor M, a normally open contact of a contactor KM and an alarm module;
the normally-closed current induction switch is arranged on an L1 phase line between the running mechanism motor M and a normally-open contact of the contactor KM; the K1 end of the contact of the normally closed current induction switch is connected to an L1 phase line between a normally open contact of the contactor KM and a three-phase power supply, the K2 end of the contact of the normally closed current induction switch is connected with a first end of a coil of the digital time relay KT, and a second end of the coil of the digital relay KT is connected with an N phase line of the three-phase power supply;
the normally open contact of the digital relay KT is instantaneously closed when the coil is electrified and is opened after a preset time; the two ends of a circuit formed by connecting a normally open contact of the digital relay KT and a coil of the intermediate relay KA in series are connected to an L1 phase line and an N phase line of a three-phase power supply; the two ends of a circuit formed by connecting the alarm module with the normally open contact of the intermediate relay KA in series are connected with the output end of the stabilized voltage power supply, and the input end of the stabilized voltage power supply is connected with the L1 phase line and the N phase line of the three-phase power supply; the alarm module comprises a loudspeaker and an optical alarm which are arranged in parallel, and the voltage provided by the stabilized voltage supply is 12V.
In this embodiment, the model of the normally closed current sensing switch is Fearlie M3086, and the normally closed current sensing switch is used for sensing the current in the line and controlling the action of the contact K1K 2; the model of the digital time relay KT is JS14P,
the specific working principle is as follows:
when the travelling mechanism motor M of the thickener works, current in a circuit passes through, the normally closed current induction switch acts at the moment, the contact K1K2 is changed from normally closed to normally open, the working power supply of the digital time relay KT is disconnected, the coil of the intermediate relay KA is not electrified, and the alarm module does not act;
when the motor M of the travelling mechanism of the thickener is in a stop state, the normally closed current induction switch contact K1K2 is in a normally closed state because no current exists in a circuit, the coil of the digital time relay KT is powered on, then the normally open contact of the digital time relay KT is closed instantly, the coil of the intermediate relay KA is powered on, the normally open contact of the intermediate relay KA is closed, the alarm module is powered on to send an audible and visual alarm signal, and a driver at a post starts the thickener again to release the alarm after the cause of the stop is processed or automatically releases the alarm after a preset time delay. The preset time in this embodiment is set to 1min.
The device utilizes the principle that current passes through when a motor works, a normally closed current induction switch is arranged on an output cable of a traveling mechanism of the thickener of the low-voltage distribution room control cabinet, and the purpose that the thickener alarms in time after an accident of stopping the traveling mechanism is stolen is achieved through linkage with a numerical time relay KT. At present, all concentrator manufacturers only design a load detection system for a rake of a travelling mechanism, namely, the rake can be automatically lifted once the load of the rake is detected to reach a certain threshold value, but the accident of theft and stop caused by the damage of a movable ring or the failure of a circuit and the like cannot be dealt with, and the design and the application of the device can make up the blank in the aspect of China.
The foregoing is only a preferred embodiment of the present utility model, but the scope of the present utility model is not limited thereto, and any changes or substitutions easily contemplated by those skilled in the art within the technical scope of the present utility model should be included in the scope of the present utility model.
