When the water pressure is too high or too low, or when the water pump is overloaded and the temperature is relatively high, the data is transmitted to the alarm box 205 through the water pressure sensor 105 and the temperature sensor 106. The alarm box 205 cuts off the power supply of the water pump and issues an alarm through the alarm lamp 206, timely notifying the staff to perform necessary repairs and avoiding adverse effects on the normal operation of the hydropower plant.

[0030] Among them, two threaded holes are symmetrically formed on both sides of the fixed block 201 and the mounting base 202. An installation screw 203 is threadedly connected to each threaded hole. The connection between the fixed block 201 and the mounting base 202 is realized through the installation screw 203. The upper end surface of the fixed block 201 abuts against the side wall of the installation groove. The alarm component 200 can be disassembled and assembled conveniently through the installation screw 203.

[0031] Among them, both the temperature sensor 106 and the two water pressure sensors 105 are electrically connected to the alarm box 205. The water pressure and temperature of the water pump can be monitored in real time through the water pressure sensors 105 and the temperature sensor 106.
