Description
Technical field
The present invention relates to sail peculiar to vessel, particularly a kind of Darrieus propulsion power generating dual-purpose type sail.
Background technology
Wind energy is the regenerative resource with extensive development potentiality, and the oil crises of the seventies in last century makes people recognize the importance of on boats and ships, carrying out Wind Power Utilization.The research of modernization sail boats and ships has become some developed countries, like the research emphasis of Germany, Japan, Sweden, Denmark etc.
Abroad facts have proved: be used for ship's navigation to sail as auxiliary power, can reduce by 10%～30% to the marine main engine oil consumption, and Marine engineerings are racked one's brains and also are difficult to the efficient of driving engine and screw propeller raising 1%～2%.For the ship that oil takes the 40%-60% that has accounted for operation cost, sail boosting technology nothing is suspected to have great temptation.Therefore, also the someone thinks: " the sail ancillary technique is the best approach of at present known reduction boats and ships oil consumption "; " boats and ships that use wind propulsion are not the resurrection of mood of recalling antiquity, but the reform of ship power ".
The nineties in last century, Japan has carried out the full scale test of hard sail on the not too big ocean range vessel of some tonnages, and the back does not obtain promoting because of reasons such as oil price drop, technological imperfection and complicated operations.The form of this sail with handle simplyr relatively, but efficient can not let the people satisfied fully, is limited by wind direction bigger to the utilization of wind.However, Japanese government is since two thousand one supporting the research of novel sail-assisted propulsion boats and ships always.
2006, Germany researched and developed kite (umbrella aerofoil profile) sail, and on 15000 tonnes of ocean range vessels, has carried out full scale test.Kite sail cost is lower, and is simple in structure, and transformation requires lowly to hull, and it is less to take the boats and ships space, but that it discharges with the control difficulty is high, higher to the requirement of wind direction.
Above hard sail and kite sail are referred to as modern sail, and the boats and ships of equipping modern sail are called the modernism sailing boat, and modernism sailing boat and traditional sail assisted ship have huge difference.
China is since the initial stage eighties, in Wuhan, area such as Guangdong, Zhejiang, Shanghai carried out the research of sail-assisted propulsion in succession, and obtained gratifying achievement.Wherein, Small fishing vessel sail boost installation by South China Science & Engineering University, Guangdong Province's aquatic products office, the common development of Guangdong Province's shipping research institute is applied on nearly thousand fishing boats in each fishing zone, Guangdong Province; But be the fishing boat of little tonnage, wind sail device is all comparatively simple with behaviour's sail system.Wuhan Water Transporting Engineering College (existing Wuhan University of Technology) has been developed many small-sized sail boosting freighters jointly with Jiangsu, Hunan shipping sector, by 708 and 711 design, 2500DWT sail-assisted propulsion synthesis energy saving multipurpose container-ship " No. 22, Mingzhou " that Ningbo ocean shipping company undertakes the construction of is Japanese in sun maiden voyage February 14 in 1996.
To sum up, above-mentioned several kinds " modern sail type " technology, energy-saving effect is not good enough, or construction and over-the-road expense are high, or the course line is required harsh, all difficult have satisfied result.Therefore, be necessary prior art is innovated, design a kind of propulsion coefficient height, stable, the tangible novel sail type of energy-saving effect of work-hours.
For the wind sail device that can be applicable on the boats and ships, disclose some patents at present, but all mainly be to advance and design-calculated basically, and the sail that can adopt propelling and the two kinds of purposes of generating electricity are used has been studied seldom to auxiliary vessel.Publication number is that CN101209752A (application number 200610148105.7) discloses a kind of to be the ocean-going freighter of auxiliary power with the sail, to comprise and far help propulsion of ship and design-calculated, and to can adopt advance and sail research that the two kinds of purposes of generating electricity are used seldom.Publication number be CN101209752A (application number 200610148105.7) to disclose a kind of be the ocean-going freighter of auxiliary power with the sail, comprise ocean-going freighter and the auxiliary sail of a cover, it is characterized in that auxiliary sail is made up of stern sail and shipboard sail two parts; This device mainly is to have utilized the wind direction more consistent with the ship running direction, promptly the wind comes from behind the ship, and the wind direction angle that can utilize is less.Publication number is that CN101314397A (application number 200810048212.1) discloses a kind of parent-subsidiary wind sailing boat; It comprises lash ship body, lash barge body, sail and sail and hull coupling link, it is characterized in that: the vertical midship section of lash ship body and lash barge body is spent less than 20 at the angle of cut in boats and ships the place ahead; At least one cover water supply and sewerage system is set in the lash barge body; This device mainly be to utilize the lash barge body for the lash ship body provides extra stability, make the lash ship body can adopt the huge Japanese hard sail of area, and then auxiliary power be provided for propulsion of ship.Publication number CN101486375A (application number 200910060732.9) discloses a kind of primary and secondary sailing vessel with mobile secondary hull; It comprises the coupling link of lash ship body, lash barge body, sail and sail and hull; The structure coupling link is connected with lash ship body and lash barge body, is a kind of connection that horizontally rotates.When using sail, retractable driving is shunk, and the lash barge body can make boats and ships obtain huge countermoment away from the lash ship body.Compare with parent-subsidiary wind sailing boat, the primary and secondary sailing vessel with mobile secondary hull major advantage is can, when navigation channel busy navigation restricted at channel span.Publication number is that CN101497369A (application number 200910071582.1) discloses a kind of hollow sailboat mast, and it is not enough for the strength of material of the load side that the symmetry that solves existing sailboat mast cross section is brought, the strength of material of load side is not brought into play and the following thick problem that thin large-scale mast is not easy to dress lug sail on masthead that completely.The cross sectional shape of the upper mast of this device and following mast is designed to hollow and big half elliptic, and this cross sectional shape makes device when wind-engaging, and the material of load side is fully used; The uniform cross section design of upper mast and following mast has guaranteed that mast tops has a bigger cross section and certain charge capacity, makes masthead that spinnaker can be installed.
Above-mentioned publication all is based on to boats and ships provides the departure point of additional thrust power to propose; But the wind direction that is faced during owing to boats and ships ocean navigation comes and go; Boats and ships sail when facing relatively unfavorable wind direction just can not produce advantageous effect even to the boats and ships generation resistance that advances to propulsion of ship, so the variation of wind direction is very big to the energy-saving effect influence of boats and ships.In addition, because the restriction of marine environment, navigation channel and bridge, the area of boats and ships use sail can not be excessive.For effectively utilizing the wind energy resources of marine environment more, need a kind of wind sail device that can flexibly, efficiently utilize wind energy of design.
