6results about How to "Realize fully automatic control" patented technology

This utility model belongs to the field of storage device technology, specifically relating to a device and system for collecting leaked ethylene glycol aqueous solution. It includes a collection tank body, a water inlet, a solenoid valve, a vent, a level gauge, a signal terminal, a drain outlet, a detection port, a controller, and a collection tank base. The water inlet is located on the top left side of the collection tank body via a straight pipe, the signal terminal is installed on the top right side of the collection tank body, and the drain outlet is located at the bottom of the collection tank body via a straight pipe. This utility model, through the coordinated design of the collection tank body, solenoid valve, level gauge, and controller, achieves automatic collection and alarm control of leaked ethylene glycol aqueous solution. When the liquid level reaches the alarm threshold, the controller automatically closes the solenoid valve at the water inlet and sends a signal to prevent the leaked liquid from continuing to spread. Simultaneously, manual collection is achieved through the drain outlet, effectively preventing the slightly toxic ethylene glycol aqueous solution from harming people and the environment, and significantly improving the safety of indoor ski resort air conditioning systems.
