Abstract
The utility model is a manhole cover with an alarm for guarding against theft, which belongs to manufacturing technology of well cover. The utility model comprises a hollow cover, a cover frame and an alarm. The cover is put on the cover frame. A trigger conducting wire is arranged between the cover and the cover frame. The trigger conducting wire is out of touch with the cover and the frame. The outlet terminal of the trigger conducting wire is connected with terminals of the cover and the cover frame, forming two trigger electrodes. The two trigger electrodes are connected with the alarm. All the connections of the trigger conducting wire in the cover and the cover frame are provided with isolators. As the utility model is provided with an alarm, any point of the cover and the cover frame will touch the trigger conducting wire when the cover has been stolen and a speech integrated chip will be short-circuited. With current on, a loudspeaker will make noise to give an alarm, placing a check on theft. The utility model has advantages of reasonable design, simple structure and convenient practice.
