Description

Tidal stop gate safety monitoring system

Technical Field

The utility model relates to the technical field of water conservancy safety monitoring, in particular to a tide gate safety monitoring system.

Background

The tide gate is built near the coastal land or river mouth for tide blocking, light storage, flood discharging and drainage. The gate is closed during tide rising to prevent tide water from flowing backward into the river channel and to block and store fresh water in the river, so that the requirements of water diversion, shipping and the like are met. When the tide is removed, the tide level is lower than the river level, and the gate is opened to discharge flood, drain waterlogging and wash silts. The tide gate has the characteristics of bidirectional water blocking, frequent operation and the like.

The tide gate consists of a gate chamber, an upstream connecting section and a downstream connecting section. The sluice chamber is a main body of the sluice and is provided with a bottom plate, a gate, a hoist, a sluice pier, a breast wall, a working bridge, a traffic bridge and the like. The gate is used for retaining water and controlling the flow of the passing gate, and the gate pier is used for separating the gate hole from the supporting gate, breast wall, working bridge, traffic bridge and the like. The bottom plate is the foundation of the lock chamber, and transmits the weight and load of the upper structure of the lock chamber to the foundation, and has the functions of seepage prevention and impact prevention. The chambers are connected to the upstream and downstream connection sections and to the two banks or other buildings, respectively. The upstream connecting section comprises wing walls and slope protection arranged on two banks, and anti-flushing grooves, bottom protection and cover arranged on a river bed, and is used for guiding water flow to smoothly enter the sluice chamber, protecting the two banks and the river bed from being flushed by the water flow, and forming an seepage path with sufficient length together with the sluice chamber, so that the seepage resistance stability of the seepage water flow along the two banks and the sluice base is ensured. The downstream connecting section consists of a stilling pool, a guard, a sea water flow, a flushing prevention groove, two-bank wing walls, a slope protection and the like and is used for guiding the water flow out of the sluice to uniformly diffuse downstream, reducing the flow speed, eliminating the residual kinetic energy of the water flow out of the sluice and preventing the water flow from flushing the river bed and the two banks.

External factors such as geology, upstream and downstream river water level change, air temperature and the like have a certain influence on the deformation of the tidal stop gate building, so that the safety operation of engineering and equipment is influenced, and even damage is caused. According to the regulation requirements of related regulations of hydraulic engineering, under normal conditions, manual vertical displacement, horizontal displacement, osmotic pressure, expansion joints and the like are required to be observed on a tidal stop gate building, but the existing monitoring method has the defects of too few manual observation and measurement times and high probability of accidental errors, and cannot timely and reliably master the deformation condition of the hydraulic engineering building, so that once geological disasters occur, and the combination of upstream and downstream special water levels or extreme weather is very likely to bring hidden danger to the safe operation of equipment and engineering. The hydraulic building deformation condition of the gate station can be dynamically mastered by implementing the automatic monitoring of the hydraulic building deformation of the gate station, so that the actual requirement of the gate station engineering for safe operation is met, and the requirements of water conservancy modernization and informatization are met.

Therefore, the present utility model provides a tide gate safety monitoring system to determine the operation state of the tide gate, and to perform real-time early warning on unsafe state, so as to ensure the engineering safe operation, which is a technical problem that needs to be solved by those skilled in the art.
