Title:
SAFETY MONITORING SYSTEM EMPLOYING BEIDOU NAVIGATION SATELLITE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/031660
Kind Code:
A1
Abstract:
A safety monitoring system employing the Beidou navigation satellite system comprises a dam pile (1), a water level detection mechanism (2) and a Beidou monitoring mechanism (3). The water level detection mechanism (2) is rotatably provided at the dam pile (1). The water level detection mechanism (2) comprises a detection box (21), a first detection plate (25) and a second detection plate (223). The detection box (21) is provided at a side surface of the dam pile (1). A supporting plate (24) is provided inside the detection box (21). A partition plate (216) is provided between the supporting plate (24) and the detection box (21). The first detection plate (25) is provided at the supporting plate (24). A rotary shaft (26) is movably connected to the first detection plate (25). The rotary shaft (26) extends through the first detection plate (25) and is provided with a rotating arm (27) thereon. In the invention, a water level can be obtained by means of a water level detection box (21) accommodating a buoy (210) and a counter weight (211) and installed at a dam pile (1) of a dam, in combination with observation of the position of an upwardly-movable rolling cylinder (221) at the second detection plate (223) and the number of turns of a connection cable (217) wound around the rotary shaft (26), such that a change in a water level can be accurately detected. Moreover, the use of the Beidou navigation system realizes remote monitoring, thereby enhancing the practicability.
