Shipping draft adjusting device and draft adjustable transport ship

Abstract

The invention discloses a ship draft adjusting device, comprising an air bag, an inflation system, a retraction mechanism and a fixed support saddle, wherein, the air bag is used for adjusting the draft area of the ship; the inflation system is used for controlling the inflation and the deflation of the air bag; the retraction mechanism is connected with the air bag, and is used for controlling the retraction of the air bag; and the fixed bearing is used for fixing the retraction mechanism on a ship body. Due to the ship draft adjusting device, the draft of the ship can be adjusted conveniently, so that the ship not only can sail on a normal water level in ocean, but also can sail on a shallow water level in offing, and the ship has the capability of run aground resistance, therefore, the requirement for transporting large materials in an offing mudflat area can be met. Based on the draft adjusting device for the ship, the invention also discloses a transport ship with adjustable draft, which comprises a plurality of ship draft adjusting devices with even number, wherein, the ship draft adjusting devices are symmetrically arranged on the two sides of the ship body. The transport ship with adjustable draft can be refitted form the original barge and the manufacturing cost is lower.

Description

technical field [0001] The invention relates to the field of ships, in particular to a device for adjusting the draft of a ship and a transport ship with an adjustable draft, which is especially suitable for the transportation of large materials in coastal tidal areas. Background technique [0002] With the increasingly severe energy situation, at present, the development of offshore wind energy is in full swing at home and abroad. When constructing a wind farm in the coastal tidal flat area, it is necessary to transport the wind turbine foundation construction materials, wind turbine parts, etc. to the work site in time. These materials and parts are not only large in quantity, but also heavy in weight (taking a 1.5MW wind turbine as an example, nearly 1,000 tons of foundation construction materials for a single set, and nearly 200 tons for a single set of wind turbine parts), but due to terrain constraints, their transportation is particularly difficult . This is because...

Problems solved by technology

For example, the Chinese Invention Patent Application Publication (CN1990342A) discloses a large-tonnage Haihe direct transport ship, which can change the height and draft of the bow through the lifting device; but because the draft is too large, it is not suitable for use in coastal beaches.

Another example is the variable draft container ship introduced in "Research and Development of 90m Multipurpose Variable Draft Container Ship" (Zou Yaoming, Jiangsu Shipbuilding, No. 2, 2002), which can adjust the draft of the ship by changing the ballast water in the ballast tank; The fat ship structure design, the minimum draft is 3.5 meters, which is not suitable for transportation in coastal tidal areas

In addition, the draft adjustment device of the above-mentioned ships has a complex structure, high cost, and inconvenient manipulation, so it is difficult to be directly applied to ordinary ships.

[0004] In addition, no other ship draft adjustment devices and large-scale material transportation tools suitable for use in coastal flat areas have been found, and no documents recording relevant contents have been found.
