Abstract
The utility model discloses a detecting device for workshops to be logged by water. The device comprises five sensors, five relays, a sluice gate, a control early warning lamp and a support. The five sensors are all fixed to the support. The first sensor, the second sensor and the third sensor are arranged on the same horizontal plane in an equilateral triangle mode to form an actuating layer. The fourth sensor and the fifth sensor are arranged on the same horizontal plane to form an early warning layer. When the workshop water level reaches the early warning layer, early warning can be achieved through the control early warning lamp as long as one sensor of the two sensors detects the water level. Even if one sensor is in fault, the detecting device can work normally. When the water level reaches the actuating layer, the sluice gate can be closed if any two sensors of the three sensors detect the water level. Thus, system false operation is avoided, and redundancy is improved.
