There is not Anti-Typhoon requirement in the present caisson gate design regulation, come interim at typhoon, because the change of level of seawater moment is very big, the buoyancy of the self-regulation gradual change that the morning and evening tides cabin causes because of morning and evening tides this moment changes function and can't normally play a role, may cause the caisson gate serious safety problem of come-up suddenly thus.Therefore how increasing negative lift is to make caisson gate possess one of key issue of Anti-Typhoon ability.
Summary of the invention
Technical problem to be solved in the utility model is the deficiency that exists at above-mentioned prior art and provides a kind of negative lift that can effectively increase caisson gate where necessary to make it possess the caisson gate of Anti-Typhoon ability.
The utility model is to address the above problem the technical scheme that is adopted to be: comprise down trapezoidal case structure dock gate body, be provided with the solid ballast cabin in dock gate body inner bottom part both sides, the centre is provided with the water intaking cabin, on the solid ballast cabin, install ballast chamber, top, water intaking cabin is an equipment compartment in the middle of in the dock gate body, both sides are provided with the morning and evening tides cabin and dispose tidal valve in the dock gate body above ballast chamber, its difference is to install water pump at equipment compartment, the input end of water pump joins by pipeline and water intaking cabin, and the mouth of water pump is by inlet channel and valve and the connection of morning and evening tides cabin.
Press such scheme, be provided with buoyancy tank above the ballast chamber of the outside in two morning and evening tides cabins, buoyancy tank lower end and ballast chamber connect, and side direction is installed dividing plate separates itself and morning and evening tides cabin, and the dividing plate height is higher than dock gate maximum functional waterline.
Press such scheme, described ballast chamber bottom is by pipeline and water pump and water intaking cabin UNICOM.
Press such scheme, the cabin structure of both sides is symmetrical in the dock gate body.
Press such scheme, middle upper part is provided with control cabin in the dock gate body.
The utility model beneficial effect is: 1, the morning and evening tides cabin of caisson gate is set to the dual-purpose cabin of morning and evening tides cabin and ballast chamber, before typhoon arrives the morning and evening tides cabin being converted to ballast chamber uses, detailed process is: make earlier that caisson gate is normal to sink in place and close all tidal valves, open valve, give the water filling of morning and evening tides cabin by water pump and inlet channel, make it be converted to ballast chamber, thereby increase considerably the negative lift of caisson gate, make it possess Anti-Typhoon ability.When there not being typhoon, use as the morning and evening tides cabin, by the tidal valve of normal occupation mode unlatching, the seawater in the morning and evening tides cabin is flowed out certainly until concordant with the sea level towards the off-lying sea, do not influence any function in morning and evening tides cabin.2, increased substantially the latent minimum longitudinal stability that floats in the process of caisson gate by buoyancy tank is set, do not lose negative lift when increasing longitudinal stability, the caisson gate safety is good.
