Abstract

The utility model relates to a marine energy-saving device of wind force boosting, and specifically relates to a wall type sail, comprising a triangle hanging beam, telescopic masts, reducing arc tethers, back ropes of slanting pulling, a choke canvas, and a canvas folding and unfolding device. The triangle hanging beam, arranged on the tops of a plurality of the telescopic masts, is integrated with the telescopic masts into one body, to form a sail body of a rectangular plate like structure and is arranged at a tail part of a boat; the triangle hanging beam is provided with a plurality of pulleys; a plurality of winches are fixed on the tail part of a boat; the canvas folding and unfolding device is arranged in the tail part of a boat; the reducing arc tethers are respectively uniformly distributed on each mast of each telescopic mast; the back ropes of slanting pulling are respectively uniformly distributed in front of each telescopic mast; one ends of the back ropes of slanting pulling are fixed with the boat and the other ends, traversing the pulley, are connected with the winches; the choke canvas is arranged between the reducing arc tethers and the back ropes of slanting pulling; and one end of the choke canvas is fixed with the triangle hanging beam, and the other end is connected with the canvas folding and unfolding device. The wall type sail has a simple structure; is conveniently operated; can prevent canvas from bending backwards and protruding outside during a heavy wind and can timely pull in the sail, so that safety is guaranteed.

Description

Wall formula sail

Technical field:

The utility model relates to a kind of energy saver of wind-force boosting peculiar to vessel, specifically a kind of wall formula sail.

Background technology:

At present, global energy is in short supply day by day, and big surprising (about 70,000 tons of/year ships) of the consumption of fuel of large-scale cargo ship and produce huge operating cost (accounting for 50%).Sail is to reduce the efficient apparatus that the ship machine consumes energy to obtain wind energy, and generally acknowledges already.But seldom adopt in the existing ship, its ship type feature of especially large-scale cargo ship just has the innate advantage that sail is installed.Why so far sail is failed to obtain to popularize and is utilized, and it is former in being: also there is the moral character defective that necessarily can not generally maybe can not be suitable in the type of existing sail.The for example current known shared pattern of many sails, the shared sail that changes of many sails acts on not strong weak property less, but a plurality of sails distribute above deck, need all when enabling and handle arrangement, time spent sail spare falls the scale of construction after rise and does not deposit inconvenience more greatly, and mast and tether can influence the facility of measurement capacity and loading and unloading operation to a certain extent.Freight container, general cargo ship class should not maybe can't adopt.

And for example German kite-type sail type, this sail type sail spare single operating is simple and direct, but the sail body is to become the free end state among being suspended in air-flow, maritime meteorology is changeable, if in input, withdrawal and use, once moment changed course of surging air-flow or eddy flow or sinuous flow, at this moment the sail body has just lost desirable effect and maybe can produce and jeopardize stable, the safe negative interaction of boats and ships.

Summary of the invention:

Goal of the invention of the present utility model is to overcome the prior art deficiency, provides a kind of simple in structure, easy to operate, rationally distributed, and the commonality height can prevent when strong wind because of canvas posttension evagination, is difficult to a kind of wall formula sail of reefing.

The purpose of this utility model is finished by the following technical solutions:

A kind of wall formula sail, comprise the triangle hanging beam, extension mast subtracts the arc tether, tiltedly draws back of the body rope, the choke canvas, canvas draw off gear, described triangle hanging beam adorn and in the top of several extension masts, fixed with it is one, constitute the sail body of rectangular plate shape structure, and be loaded on the afterbody of hull; On the described triangle hanging beam some pulleys are housed; The afterbody of described hull is consolidated with some winchs, and the canvas draw off gear is equipped with in its inside; Described subtracting on the uniform respectively every joint mast that is loaded on each extension mast of arc tether; The described uniform respectively the place ahead that is loaded on each extension mast of back of the body rope of tiltedly drawing, one end and the hull fixedly other end are passed pulley and are connected with winch; Described choke canvas is loaded on and subtracts the arc tether and tiltedly draw between the back of the body rope, and one end and triangle hanging beam are fixed, and the other end is connected with the canvas draw off gear.

Adopt technique scheme, compared with prior art, the utility model has the advantages that:

The utility model is simple in structure, and is easy to operate, rationally distributed, and the commonality height can prevent canvas posttension evagination when strong wind, and reefing in time ensures safety.

Description of drawings

Fig. 1 is a front view of the present utility model.

Fig. 2 is a right elevation of the present utility model.

Among the figure: triangle hanging beam 1, extension mast 2, choke canvas 3 subtracts arc tether 4, tiltedly draws back of the body rope 5, hull 6, fluid pressure drive device 7, support roller 8, cylinder 9, winch 10, pulley 11." ← " is wind direction, and dotted line is the profile scope signal of canvas breadth.

The specific embodiment:

See Fig. 1, Fig. 2, a kind of wall formula sail comprises triangle hanging beam 1, extension mast 2, choke canvas 3 subtracts arc tether 4, tiltedly draws back of the body rope 5, hull 6, fluid pressure drive device 7, support roller 8, cylinder 9, winch 10, pulley 11.Triangle hanging beam 1 adorns and in the top of several extension masts 2, fixed with it is one, constitutes the sail body of rectangular plate shape structure, and is loaded on hull 6 afterbodys; Some pulleys 11 are housed on the triangle hanging beam 1; Hull 6 afterbodys are consolidated with some winchs 10, and the canvas draw off gear is equipped with in its inside; Subtract on the uniform respectively every joint mast that is loaded on each extension mast 2 of arc tether 4; Tiltedly draw back of the body rope 5 uniform respectively the place aheads that are loaded on each extension mast 2, one end and the hull 6 fixedly other end pass pulley 11 and are connected with winch 10; Choke canvas 3 is loaded on and subtracts arc tether 4 and tiltedly draw the back of the body to restrict between 5, and one end and triangle hanging beam 1 are fixed, and the other end is connected with the canvas draw off gear.The canvas draw off gear is by cylinder 9, support roller 8, and fluid pressure drive device 7 is formed, and cylinder 9 is housed on the fluid pressure drive device 7; Support roller 8 is loaded on the below of cylinder 9 respectively, and choke canvas 3 is equipped with between cylinder 9 and the support roller 8 in the both sides of fluid pressure drive device 7.
