Problems solved by technology

[0004] However, there are the following deficiencies in the existing technology: (1) The construction cost of the bulbous bow is too high, and the design requirements for the bulbous bow are high. If the design is not good, it will not reduce the resistance, but will increase the resistance; (2) Drag reduction requires modification of the bottom of the ship, and the cost of the air bubble device is relatively high; (3) energy-saving shaft brackets are mostly used on high-speed ships, and have little effect on medium- and low-speed ships
In addition, there have been no reports on the application of composite energy-saving methods to river-sea direct ships

Embodiment Construction

[0028] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0029] The composite energy-saving river-sea direct ship shown in the figure includes a hull 1 and a rudder 2 installed at the tail of the hull 1. The parallel center body 3 of the hull 1 is provided with evenly spaced micro-grooves 4 in parallel along the horizontal direction. Both sides of the rudder 2 are symmetrically provided with thrust fins 5 in opposite directions. In this way, by combining the two energy-saving methods of the micro-groove 4 and the thrust fin 5 on the river-sea direct ship, energy consumption is reduced and the energy-saving effect of the ship is improved.

[0030] In the above technical solution, the central axis of the micro-groove 4 coincides with the central axis of the ship parallel body 3, and the ratio of the length of the micro-groove 4 to the ship parallel body 3 is 0.48-0.52:1. In this way, conside...

Abstract

The invention discloses a composite energy-saving river-sea direct ship which comprises a hull and a rudder installed at the tail portion of the hull. Miniature grooves distributed evenly at intervals are arranged on a ship parallel middle body of the hull in parallel in the horizontal direction. Thrust fins in the opposite directions are symmetrically arranged on the two sides of the rudder. Two energy-saving modes achieved through the miniature grooves and the thrust fins are combined and applied to the river-sea direct ship, a resistance reducing effect is achieved, and the propelling efficiency of the ship is improved, so that energy consumption is reduced, and the energy-saving effect of the ship is improved.

Description

technical field [0001] The invention relates to a river-sea direct ship, in particular to a composite energy-saving river-sea direct ship. Background technique [0002] As people pay more and more attention to the natural environment and awareness of environmental protection, energy conservation, environmental protection, and low-carbon emission reduction have become a long-term strategic policy for the development of the national economy of various countries, and it is also an inevitable choice. In July 2011, the International Maritime Organization (International Maritime Organization) held the 62nd meeting of the Marine Environmental Protection Committee, which established the "Ship Energy Efficiency Design Index" EEDI ship energy efficiency standard, and put forward new and stricter requirements for ship operation and design and construction. The discussion and research on ship energy-saving and environmental protection technology is particularly important. [0003] EEDI...
