A real-time wireless monitoring device for early warning of bridge overturning

Abstract

The invention relates to a real-time wireless monitoring apparatus for early-warning on integral overturn of a bridge. The real-time wireless monitoring apparatus comprises a box, a slide rheostat, a fixed protective resistor, a voltage measuring instrument with a signal transmission device, a power source, a beam side surface fixing plate, a main beam limiting plate and a displacing vertical rod; the box is fixed on a pier by use of a pier connecting bolt; the slide rheostat, the fixed protective resistor and the voltage measuring instrument with the signal transmission device are arranged in the box; the slide rheostat, the fixed protective resistor and the power source are connected in series to form a circuit; the voltage measuring instrument with the signal transmission device is connected to the two ends of the slide rheostat; the beam side surface fixing plate is fixed on a main beam by use of a beam side surface fixing bolt; the main beam limiting plate is bent and connected with the beam side surface fixing plate; one end of the displacing vertical rod is connected to the main beam limiting plate, while the other end of the displacing vertical rod is connected to the sliding end of the slide rheostat. Compared with the prior art, the real-time wireless monitoring apparatus is capable of sending out relative vertical displacement between the main beam of the bridge and a support by use of a wireless signal in real time.

Description

technical field [0001] The invention relates to a monitoring device, in particular to a real-time wireless monitoring device for early warning of overall overturning of a bridge. Background technique [0002] During the use of bridges, in order to avoid property loss and life hazards caused by bridge overturning, the structure of bridges is generally improved or reinforced to avoid bridge overturning. For example, Chinese patent CN103205927A discloses a bridge anti-overturning pier support mechanism, which solves the problem that single-column pier bridges in the prior art use single-point support beams to easily cause the supporting seat to be empty, and even overturning accidents occur. Chinese patent CN103452053A discloses an anti-overturning reinforcing device for a single-column pier bridge, which includes a single-column pier, a widening structure is provided on the upper end of the single-column pier, and a support is provided on the top of the widening structure.

Problems solved by technology

In the past, due to the excessive concentration of load on one side of the bridge, the lateral force of the structure was unbalanced, resulting in the overturning of the bridge girder to one side. In order to solve the above problems, it is necessary to develop a real-time wireless monitoring device for early warning of the overall overturning of the bridge, so as to detect danger in time. bridge and deal with it in a timely manner
