push catamaran

Abstract

The invention provides a push catamaran comprising a barge and two push boats. The barge is provided with two parallel barge semi-hulls and a barge cabin crossing the barge semi-hulls in a connected manner. The push boats are hinged to the rear ends of the barge semi-hulls. Each push boat at least comprises a push boat semi-hull and a push boat cab located on the upper portion of the push boat semi-hull. Each push boat is provided with a power unit. A pod paddle is mounted at the rear end of each push boat semi-hull and comprises an adjustable immersion depth propeller and a guide cover covering the propeller. The barge cabin is provided with one or a plurality of rotor sails at the top, wherein each rotor sail can open or close according to wind conditions. Each rotor sail comprises a mast, a sail base and a plurality of sail subunits. A push power part in a body of the push catamaran is separated from a holding part, so that utilization rate of power equipment of the push catamaran can be increased; the novel rotor sails are used for assistance, so that wind energy is effectively utilized, energy loss is reduced, and building and operating costs are saved.

Description

technical field [0001] The invention relates to the technical field of ships and ship-related equipment, in particular to a push-pushing catamaran. Background technique [0002] When the push barge is transported, the barge is in front and the pusher is behind. It is generally put into operation in the form of a fleet. One pusher can be matched with multiple barges. It has good maneuverability and reduces resistance compared to tugboats. rudder equipment and crew, thereby reducing transportation costs. [0003] Push barges are widely used in Europe and America, among which the series of push barges designed and manufactured by Crowley Company and BludWorth Marine Company are more famous, which mainly transport crude oil and chemicals. Recently, the LNG push barge designed by WallerMarineInc. and Houston has been certified by the American Bureau of Shipping. In my country, push barges are mainly used in inland rivers. They are simple in structure, and most of them are not s...

Problems solved by technology

[0010] The main disadvantages of traditional canvas sails are complicated operation and low utilization efficiency of wind energy, which often requires a huge canvas to generate relatively reliable and effective power propulsion

Rigid sails are mainly based on the principle of wing aerodynamics, and the utilization efficiency of wind energy is higher than that of canvas sails, but the ratio of the aspect ratio of the sails is relatively large, and it is difficult to furl the sails, making it difficult to enlarge

The kite sail has a strange shape, but it is difficult to control, and the use of wind energy is unstable

The main problem with turbosails is that they need to be installed with a turbo fan to inhale air, which is complicated to make and consumes energy.
