Manhole device for detecting and alleviating flooding
A recently granted patent (Publication Number: US11920318B2) describes a unique manhole device designed to address issues related to flooding and debris collection. The device includes a manhole cover with a float body coupled to it, along with a canister that houses the float body and features a valve to control liquid flow. Multiple float guides connect the manhole cover to the canister, allowing the float body to raise the cover as liquid collects in the canister. The valve is designed to open when the float body raises the cover, preventing liquid from flowing through the primary opening in the canister when closed. Additionally, the device incorporates features such as a ratchet mechanism to secure the raised position of the cover, a strobe light for visibility, and sensors connected to a microprocessor for detecting flooding and activating communication with an external system.
Furthermore, the patented manhole device includes innovative elements like a debris removal device, activated by sensors detecting debris accumulation around the cover. This device can be a fan or a compressed air canister, designed to move air through spaces between the cover and the canister, effectively clearing debris away from the manhole. The multiple float guides in the device have magnets at their ends, allowing them to be raised independently of the cover and securely held in place when in an unlocked and raised position. The incorporation of a GPS unit for location identification and various sensor-triggered communication mechanisms enhance the functionality and efficiency of this advanced manhole device, offering solutions for managing flooding and debris in urban infrastructure.
