Water Leakage Automatic Alarm Device for Upper Wind Tunnel Air Cooler

Abstract

The invention relates to an automatic water leakage alarm device for an air cooler in an upper wind tunnel, comprising: an air cooler main body, a first water tank arranged under the air cooler main body, a second water tank arranged on the right side of the first water tank, and a third water tank arranged on the first water tank and below the second water tank, the central control processor determines the state of the first solenoid valve according to the temperature and liquid level of the water in the water collecting bucket, and controls the opening of the first solenoid valve according to the liquid level in the water collecting bucket. The time is determined, and finally the next opening time of the first electromagnetic valve is adjusted according to the opening time interval of the first electromagnetic valve, and the central control processor is based on the real-time liquid level in the first water tank. Determine the sounding state of the speaker, and determine the state of the second water tank according to the pressure data of the pressure sensor. Finally, according to the water accumulation situation of the second water tank, the warning type of the current warning light and the sounding state of the speaker, the warning light and the speaker are adjusted. Adjustment.

Description

technical field [0001] The invention relates to the technical field of automatic water leakage alarm devices, in particular to an automatic water leakage alarm device for an air cooler in an upper wind tunnel. Background technique [0002] The abbreviation of air cooler is air cooler, which is the most widely used heat exchange equipment for cooling in the power generation process of hydropower stations. The current cooling method adopts closed self-circulating air cooling, and the air cooler is equipped with cooling water pipes. When the air cooler leaks, if the fault information is not received in time, the leaked water may directly enter the generator, causing damage to the stator coil insulation, grounding or phase-to-phase short-circuit faults, endangering the safety of the equipment and seriously affecting the stable operation of the unit. Moreover, the air cooler of the generator is generally installed in the upper wind tunnel, which is a confined space, and daily ins...
