Document Type and Number:
WIPO Patent Application WO/2023/207192
Kind Code:
A1
Abstract:
Disclosed are an anti-freezing protection safety alarm device for a bridge pier in water in a cold region, and an installation method. The device comprises a solar panel, a storage battery, anti-freezing devices, slings, and an alarm transmitter; each anti-freezing device comprises a suspension lug, an inner steel plate, a bottom steel plate, an outer steel plate, springs, an electric heating wire piece, a heating control switch, an alarm control switch, and silicone rubber. According to the present invention, three-level safety protection can be adaptively provided for a bridge pier depending on the deformation degrees of the anti-freezing devices; when deformation is small, an ice load is reduced by means of the good deformation capability of the devices; when deformation exceeds a certain value, a heating function is enabled to melt an ice layer to reduce the ice load; when an extreme state occurs and deformation of the devices exceeds a limit, the alarm device is triggered to ensure the safety of a bridge. The anti-freezing devices can be subjected to unit-type standardized design and manufacturing, the width size is determined according to conditions of transportation, installation and the like, the required number is determined according to the size of the bridge pier, it is flexible to use, and the adaptability is high.
