The present invention relates to marine propulsion and method.
The present invention is particularly suitable for but is not limited to be used in the propelling of canoe and barge.For ease of explanation, describe with reference to this special purpose.Yet, should be appreciated that the present invention also can be used for other boats and ships, as naval vessels and air cushion vehicle etc.As qualification, term " canoe " is used to represent any type of boats and ships, comprises above-mentioned boats and ships.
Propulsion of ship is realized by the horizontal shaft screw propeller that a main frame such as steam engine, combustion engine or one of direct motor drive pull the plug fully usually.If main frame or engine installation are in board, its installation site must be positioned on the axis of screw propeller, and the inside taper gradually of hull afterbody, so that water flows into screw propeller.Because the space of many installation main frames has been lost in the influence of these requirements, and the passage that changes with service engine also usually is restricted.Need to provide in addition steering hardware in addition, normally adopt the form of rudder.
Another kind of promotion program is to adopt outboard motor, and one of them driving engine and screw propeller that is installed in the bottom that is installed in top all places on the common support, this support can around one greatly to the vertical pivots swing so that turn to.Driving engine must be connected by driving system with screw propeller, and such driving system may be complicated, costliness and be difficult to maintenance.Because outboard motor is minimum and be suspended on the afterbody of ship from buoyancy, thereby the balance that may seriously jeopardize the canoe that joins with it.Be used to advance the high-power outboard motor of this class of heavy barge and similar boats and ships very heavy, need carry out dismounting with hoisting crane.
In fact, boats and ships such as similar barge need move with towboat, and this class ship has quite a few time at anchorage possibly.In this process,, also exist other problem though reduced the needed host number of train of barges.A towboat must build that independently canoe is the same as one, and the enough again ambassadors of crewman's accommodation should be arranged, and it possesses marine working ability.Provide the cost of every main frame of power very high for towboat like this.
When being coupled together, towboat and barge also can run into some common problems.If connect towboat and barge with hawser, two ships contouring by oneself then, but reduced the maneuvering ability of towboat to barge.If connect or be rigidly connected towboat and barge with vertical pivots, can improve maneuvering performance greatly, but the mutual action load of wave action on the towboat housing be also quite big.
The objective of the invention is to reduce above-mentioned defective, and a short failure-free, effective propelling unit are provided.Other purpose of the present invention and advantage can obviously be found out by following description.
