Abstract
The present invention provides a manhole monitoring system including: a smart monitoring device installable on to a manhole cover; and a shape adapter installable on to a base frame mated with the manhole cover. The smart monitoring device includes a pressure sensor configurable to cooperate with the shape adapter to detect existence of the manhole cover at the base frame. The manhole monitoring system can be installed on site or off site by workers without entering into the confined space in the manhole. The present invention not only prevents working accidents caused by hazards in the confined space, but also significantly reduces the time and manpower for installation.
Claims11
A manhole monitoring system, comprising:
- a smart monitoring device installable on to a manhole cover;
- and
- a shape adapter installable on to a base frame mated with the manhole cover;
- wherein the smart monitoring device includes a movement sensor configurable to detect a presence of the manhole cover on the base frame;
- the movement sensor includes a transmission system and a transducer mechanically coupled with or linked to the transmission system;
- when the manhole cover is placed on the base frame, the transmission system is configured to transfer a force exerted by the base frame to the transducer to trigger the transducer to generate an electrical signal indicative of that there is a manhole cover placed on the base frame;
- and
- when the manhole cover is removed from the base frame, the transducer is released from the transmission system and switched to generate an electrical signal indicative of that there is no manhole cover placed on the base frame.
