Description

The box-shaped floating dock gate that a kind of hold is open

Technical field

The present invention relates to the dock installation manufacturing, the box-shaped floating dock gate that specifically a kind of hold is open.

Background technology

Dock gate is an important component part of making (repairing) dock the modern times.It can block the water outside the depressed place when closing, and makes dock chamber not by water logging, builds the environment of building ship operation substantially dry.Open interior water of back dock chamber and the water outside the depressed place and join together, boats and ships just can conveniently pass in and out.Owing to make the on-site hydrology of (repairing) dock, water quality, meteorology, silt alluvial situation and condition differences such as operating needs, manufacturing and maintenance, polytype dock gate has appearred, adopt more have floating dock gate and flap caisson.Dock gate flew at the water surface when floating dock gate was opened, and rested in the place, berth, earlier dock gate was entrained back into the dock entrance appropriate location when closing, and the vertical subsidence of door body is located in to the bottom then.Be provided with ballast chamber in the floating dock gate body, the heavy or floating water that relies on the interior water filling of ballast chamber or discharge in the ballast chamber of dock gate is realized.

Box-shaped floating dock gate is to adopt maximum a kind of floating dock gates on the dock, and its a door body cross-sectional plane is a rectangle, and six faces forming the door body profile all are rectangles, and outside plate is the plane, and most of members are linears, make easily.Its top breadth is the same with the door body thickness, helps bearing hydraulic pressure.Its bottom is broad, be convenient to adopt low unit weight ballast, and the ballast piling height is little, and is favourable to the center of gravity that reduces dock gate.All outside dock entrance, it is long not account for the depressed place for its door body at closing time, and shortcoming is that displacement is big, the ballast amount is many.

Common box-shaped floating dock gate it be with the deck dock gate by highly being divided into two-layer or three layers, Fixed Ballast is at the bottom, the pump valve cabin is located at bottom or middle level, the upper strata all is a ballast chamber double as morning and evening tides cabin usefulness, the part of middle level and bottom also is a ballast chamber.Such subdivision design, buoyancy is in the superiors of dock gate all the time during the dock gate sink-float, can satisfy the requirement of dock gate sink-float stability at an easy rate, need discharge a large amount of ballast waters when shortcoming is floating, and power consumption is very big, and floating is chronic.As satisfying floating time requirement, just must increase the ability of water pump or the quantity of increase water pump.The pumping gear quantity that causes dock gate to dispose increases, generating capacity is big, pipeline is complicated, has not only increased investment and has also increased operating charges and maintenance expense in the future, and is very uneconomical.It is that the deck is divided into three layers to the dock gate height to also have a kind of subdivision design, and Fixed Ballast below lower deck, is the morning and evening tides cabin more than the tween deck all, and pump valve cabin and ballast chamber are located between the middle lower deck.Though need discharge a large amount of ballast waters and the very big problem of power consumption when the design of such subdivision has solved floating, but still exist equipment disposition quantity many, the pipeline complicated situation, the floating stationarity of dock gate takes place freely not influence because of the water outlet of morning and evening tides cabin easily, and morning and evening tides cabin silt lodging easy-clear not, influence the safe in operation of dock gate.

Flourish along with China's ship building industry, the large-scale and large of scale of construction trend of domestic making (repairing) dock, the dock entrance width greater than 100 meters be not indivedual cases.Large-scale and superhuge box-shaped floating dock gate displacement is big, number of devices is many, generating capacity is big, pipeline is complicated and the water outlet of morning and evening tides cabin is smooth, the problem of easy-clear is particularly not outstanding in silt lodging.

Summary of the invention

The box-shaped floating dock gate that a kind of hold that the objective of the invention is to provide at the deficiencies in the prior art is opened, the sink-float good stability, control operation is convenient, the pipeline system setting is more simple, significantly reduced equipment operation and maintenance cost, and the water outlet of morning and evening tides cabin is unobstructed, silt lodging is removed easily.

The object of the present invention is achieved like this: the box-shaped floating dock gate that a kind of hold is open, comprise a body and be arranged on a body interior ballast chamber, morning and evening tides cabin, hold, pump valve cabin, characteristics are that the base plate of a body is provided with solid ballast, are arranged with the ballast chamber of cross section for " L " shape in the body and on the solid ballast; Between two ballast chambers and door body middle part is provided with the deck, and the upper strata, deck is divided into several morning and evening tides cabins, the lower floor middle part is provided with hold, and hold two ends and top are the pump valve cabin.

Described ballast chamber is symmetricly set on two ends or hold two ends in the body.

Described solid ballast is cast-in-place heavy concrete.

Through hole or both sides that described hold bottom is provided with rear opening body base plate, solid ballast are provided with through hole.

Described pump valve cabin is provided with servicesubway.

The bottom in described morning and evening tides cabin is provided with the straight tube of rear opening body base plate or the connection pipe that communicates with hold.

The present invention adopts rational subdivision design, compared with prior art having light load displacement (being the total weight of dock gate) reduces more than 20 percent, solid ballast reduces about 30 percent, generating capacity reduces more than 50 percent, the pipeline system setting is more simple, it has not only improved the sink-float stability of dock gate, and the water outlet of morning and evening tides cabin is unobstructed, silt lodging is removed easily, even trim takes place also easily in control in dock gate during sink-float, safety is good, control, the operation all very convenient, saved investment and everyday devices operation and maintenance cost greatly.
