Embodiment 1

[0018] See attached Figure 1~2 , the present invention comprises a door body 1 and a ballast water tank 2, a tidal tank 3, a bilge 4, and a pump valve cabin 6 arranged in the door body 1. The door body 1 is a rectangular box body, which consists of a panel, a bottom plate and a side The solid ballast 7 of cast-in-place heavy aggregate concrete is provided on the bottom plate of the door body 1. The bottom surface of the solid ballast 7 is the same size as the bottom plate of the door body 1, and its height is determined according to the displacement. Both ends of 1 and the solid ballast 7 are symmetrically provided with a ballast water tank 2 with an "L" shape in cross-section; the solid ballast 7 is in the form of a water collection well in the ballast water tank 2, and the There is a deck 11 between them. The deck 11 divides the door body 1 into upper and lower layers. The upper layer is divided into several tidal tanks 3 by a watertight transverse tank. It is the valve co...

Abstract

The invention discloses a box-shaped floating dock door with an open bilge. For solid ballast, ballast water tanks with an "L" shape are symmetrically arranged in the door body and on the solid ballast; a deck is provided between the two ballast water tanks and in the middle of the door body, and the upper deck is divided into several tidal tanks and the lower deck. There is a bilge in the middle, and pump valve compartments at both ends and top of the bilge. The present invention adopts a reasonable subdivision design, and compared with the prior art, it has light-load displacement, solid ballast, and greatly reduced installed capacity. The sinking and floating stability and safety are better, which greatly saves investment and daily equipment operation and maintenance costs.

Description

technical field [0001] The invention relates to the manufacture of dock equipment, in particular to a box-shaped floating dock door with an open bilge. Background technique [0002] Dock doors are an important part of modern shipbuilding (repair) docks. When it is closed, it can block the water outside the dock, so that the dock room will not be flooded, and create a basically dry environment for ship repairing and building operations. After opening, the water in the dock chamber is connected with the water outside the dock, so that ships can enter and exit conveniently. Due to the differences in hydrology, water quality, meteorology, sedimentation conditions, and use requirements, manufacturing and maintenance conditions of the dock where the dock is built (repaired), various types of dock doors have appeared, and floating dock doors and lying down dock doors have been used more often. Type dock door. When the floating dock door is opened, the dock door floats on the wat...
