Description
Technical Field
[0001] The utility model relates to the field of water collection well drainage, in particular to an automatic water collection well drainage device. Background Art
[0002] The auxiliary cooling water system is a water circulation system used to cool auxiliary equipment. It is mostly used in industrial fields such as power plants and aluminum product production. The rectifier circulating water pump room is one of the most important components of the rectifier auxiliary cooling system. In order to ensure the safe operation of the circulating water and prevent the circulating water pump room from being flooded, a water collection well is set to prevent the circulating water pump room from being flooded. When the circulating water cooling pump has a serious water leakage, the water in the water collection well continues to rise. When the water level reaches a certain height, the level control relay outputs a signal when the liquid level meter monitors the water level to reach a certain height. At this time, the buzzer in the remote control room sends an alarm signal to remind the on-duty personnel to check and confirm and take action.
[0003] The water in the water collection well contains a certain amount of impurities and foam, which affects the monitoring sensitivity and accuracy of the level meter during measurement. In addition, the liquid level fluctuation in the water collection well during monitoring also makes the level meter's measurement of the liquid level inaccurate. Generally, a protective cover is installed on the measuring rod at the bottom of the level meter to prevent the impurities in the water collection well and the page fluctuation from affecting the liquid level monitoring. However, the level meter protective cover will still be affected by impurities and page fluctuations, which will affect the measuring rod at the bottom of the level meter.
[0004] The prior art discloses some invention patents related to water collection wells in the field of self-drainage technology, among which the utility model patent with publication number CN218757872U discloses an automatic drainage device for a water collection well, including a protective cover, the lower end of the protective cover is an opening as a water inlet, the upper end of the protective cover is connected to a flange, a signal transmitter is installed on the flange, a sensor signal fixing rod with an upper end connected to the flange is provided in the protective cover, the sensor signal fixing rod is electrically connected to the signal transmitter, and a magnetic float ball is installed on the sensor signal fixing rod through a float sleeve bearing. However, the problem of timely and accurate liquid level monitoring in the water collection well is still not solved.
[0005] In view of this, the inventor conducted in-depth research on how to provide an automatic drainage device that can accurately and timely monitor the liquid level in a water collection well, which led to the present case. Utility Model Content
[0006] In order to overcome the problem in the prior art that desulfurization wastewater is blocked inside the pipeline and does not affect the normal desulfurization process, the utility model provides an automatic drainage device for a water collection well, including a water collection well, which is embedded in the ground, and a baffle is arranged near any edge of the water collection well, and the side inside the water collection well and the baffle form a metering hole, a filter hole is arranged at the bottom end of the baffle, a fixing frame is mounted on the upper end of the metering hole, and a liquid level meter is mounted on the upper end of the fixing frame.
