Floating sail-banning device

Abstract

The invention discloses a floating sail-banning device, comprising a suspension cable part, two auxiliary suspension cable parts, two wire slides, buoys and positioning embedded parts. The two ends ofthe suspension cable part are fixed to the two positioning embedded parts respectively which are arranged on a river bank or a dam; each positioning embedded part corresponds to one wire slide and one auxiliary suspension cable part; two ends of the wire slides are fixed to the different elevations of the river bank or the dam; one ends of the auxiliary suspension cable parts are connected with the suspension cable part; the other ends of the auxiliary suspension cable parts are slidably connected with the wire slides via ring fasteners. The suspension cable part and the auxiliary suspensioncable parts are connected with the buoys. Compared with existing sail-banding measures, the floating sail-banning device can spatially isolate a sail-banning area in a reservoir from vessel activities, is adaptive to level changes of the reservoir, helps effectively improve engineering safety, has suitable manufacturing cost, is convenient to mount, operate and maintain and has good popularizationvalue.

Description

technical field [0001] The invention relates to the technical field of water navigation management, in particular to a floating anti-navigation device. Background technique [0002] For water conservancy and hydropower projects, especially projects with large storage capacity, good water quality and beautiful scenery, local residents have developed aquaculture, tourism and other industries in the reservoirs in order to get rid of poverty and become rich. It often happens that fishing boats block fishing and electric fishing in highly dangerous areas such as power inlets and tailwater outlets, tourist boats carry passengers into the waters near the dam for sightseeing, etc., coupled with the cargo navigation of the river itself, these frequent boats The activities pose a safety threat to structures or equipment such as dams, intake trash racks, and spillway working gates of water conservancy and hydropower projects. [0003] For this reason, project operators generally condu...

Problems solved by technology

[0004] However, the above methods do not isolate the no-navigation area in space. There are often ships intentionally or unintentionally breaking into the no-navigation area, which poses a safety threat to the operation of the project, and some even cause safety accidents, resulting in personal accidents and affecting the operation of the project. cause large economic losses

[0005] If a closed no-navigation route is set on the water surface to isolate the no-navigation area from space, the above problems will be solved very well, but at present, such no-navigation devices are still blank in the industry

The main difficulties faced in the design of the no-navigation device are as follows: (1) The storage capacity of the reservoir is large, the span of the no-route route is large, and the surface flow velocity is very high during the flood discharge of the reservoir, resulting in a large load on the main suspension cable of the no-navigation device; (2) the closed no-route route Need to adapt to changes in the water level of the reservoir, such as high-head hydropower projects, deep reservoirs, large water level fluctuations, and the water level fluctuations can reach more than 60m. If guide buoys are used to adapt to water level changes, floating guide trough buildings need to be built in the reservoir, and the cost is too high , and the location of the points is extremely inflexible

Limited by the above difficulties, similar devices, such as ship blocking devices in shipping buildings, trash discharges at power station water inlets, and prohibited routes on the coast, cannot meet the requirements. Therefore, it is urgent to design and research a new No-navigation device used in water conservancy and hydropower engineering reservoirs
