Novel water suction and drainage device for ships

Abstract

The invention discloses a novel water suction and drainage device for ships. The device includes a main water inlet pipe and a main drainage pipe, disk-shaped limiting plates are integrated with and arranged on one end of the main water inlet pipe and one end of the main drainage pipe respectively, a first main hollow structure and a second auxiliary hollow structure are arranged at the center ofthe interior of the main water inlet pipe, and a second main hollow structure is arranged at the center of the interior of the main drainage pipe; a turbine installation space communicated with the first main hollow structure and the second auxiliary hollow structure is formed in the portion, between the first main hollow structure and the second auxiliary hollow structure, of the center of the interior of the main water inlet pipe, and the portions, at both ends of the turbine installation space, of the main water inlet pipe are penetrated through by a main rotating shaft. Not only can a water suction function be achieved, but also a drainage function can be achieved. Additionally, the device can not only change the water suction efficiency but also improve the drainage efficiency, so that the regulation and control between the water suction function and the water drainage function are changeable, the changeable range is wide, and the practicability is high.

Description

technical field [0001] The invention relates to the technical field of ship machinery, in particular to a novel ship draft and drainage device. Background technique [0002] At present, in terms of ships, large ships are used in order to realize the transportation of heavy objects at sea, and when large ships are working, in order to reduce the pressure of the liquid on the bottom of the ship, fixed draft and drainage devices will be installed. The difference between them reduces the influence of liquid pressure on the bottom of the ship, and then discharges the water, so as not to affect the normal operation of the ship. However, the general draft and drainage devices are separated and set. During use , can not effectively regulate and control, and has certain limitations. Contents of the invention [0003] The object of the present invention is to provide a novel draft and drainage device for ships to solve the problems raised in the above-mentioned background technolog...
