The water conservancy and hydropower engineering, especially the engineering with large storage capacity, good water quality and beautiful scenery, has local residents becoming lean and rich, and is widely used in the industries of aquaculture, tourism and the like in reservoirs. The phenomena that fishing boats catch fish and electric fish in high dangerous areas such as a power generation water inlet and a tail water outlet, tourist ships carry passengers to enter a water area close to a dam for sightseeing and playing, and the like, and the phenomenon that the ships of the rivers themselves are used for carrying out freight navigation often occur, and the frequent ship activities form safety threats to buildings or equipment such as the dam, the water inlet trash rack, the spillway working gate and the like of the hydraulic and hydroelectric engineering.
Therefore, engineering operators generally carry out safety assessment on the reservoir area, delimit the restricted-navigation area, and prohibit local resident ships and navigation ships from entering the restricted-navigation area by adopting the modes of file transmission, personnel on duty patrol, navigation buoy setting, on-shore or high-altitude warning sign erection and the like.
However, the above modes do not spatially isolate the no-voyage area, and ships often intentionally or unintentionally break into the no-voyage area to form safety threat to engineering operation, and the safety accident is caused individually or even, so that personal accidents are caused, and great economic loss is brought to the engineering operation.
If a closed no-navigation line is arranged on the water surface, the no-navigation area is isolated from the space, the problems can be well solved, but the no-navigation device is still blank in the industry at present. The main difficulties faced by the design of the navigation control device are as follows: (1) The reservoir capacity is large, the navigational inhibition line span is large, and the surface flow rate is high when the reservoir discharges floodwater, so that the main suspension cable load of the navigational inhibition device is large; (2) The closed navigation forbidden line is required to adapt to reservoir water level change, such as high-head hydroelectric engineering, the reservoir is deep, the water level amplitude is large, the water level amplitude can reach more than 60m, if a guide pontoon is adopted to adapt to the water level change, a floating guide groove building is required to be built in the reservoir, the manufacturing cost is too high, and the distribution position and the position are inflexible. The device is limited by the difficulties, and similar devices such as a ship blocking device in a shipping building, a power station water inlet dirt blocking row, a coastal navigation forbidden line and the like cannot meet the requirements, so that a brand new navigation forbidden device applied to a water conservancy and hydropower engineering reservoir is urgently designed and researched in the industry.
