Wherein, main ship is made of main ship upper body 1, three main pillars 3 and main submerged body 2 down.Auxilliary ship is made of auxilliary ship upper body 4, auxilliary pillar 6 and auxilliary submerged body 5 down.The part that main ship and auxilliary ship pass the water surface is three main pillars 3 and two auxilliary pillars 6, makes trimaran form the structure of small-waterplane-area, has reduced the wave making resistance that trimaran navigates by water significantly.Three electric propulsion devices 23 are installed in the stern of main ship upper body 1 and two auxilliary ship upper bodies 4 respectively, and two dagger plates 16 are suspended on 1 outboard both sides, main ship upper body respectively.
The solar energy photovoltaic array can continue generating, outgoing current under the irradiation of sunlight.When solar power was sufficient, the direct current (DC) that the solar energy photovoltaic array sends was modulated to suitable electric current and voltage levvl by charging-discharging controller 18, is transported to the input end of super capacitor group 19, to 19 chargings of super capacitor group.Super capacitor group 19 electric energy stored can be used at any time, to drive boats and ships.Be used to drive angle of rake electric energy and change alternating current into, introduce the input end of electric propulsion device 23 via voltage transformer 22 by inverter 21.When the enough electric current output of solar energy photovoltaic array out of reach, when wind-force is not enough to drive boats and ships again, current distributor 17 control electromagnetic contactors 20 UNICOMs make the input end discharge of super capacitor group 19 to inverter 21.Electric current is introduced the input port of the electric propulsion device 23 of main ship, auxilliary ship through voltage transformer 22 after the mouth of inverter 21 flows out.Under the driving of the electric propulsion device 23 of main ship, boats and ships advance.The electric propulsion device 23 of auxilliary ship driving under, two collaborative main ships of auxilliary ship are adjusted relative position, the arranged distribution of straight line before and after forming, perhaps according to instruction, collaborative adjustment orientation separately, the accurate transformation takes place in the angle of facining the wind of traction solar wind sail, even boats and ships under the situation of side headwind, still can move ahead smoothly.
When wind-force was excessive, last sail beam 9, topsail beam 11 and the beam 12 that lowers the sail can both be according to instructions and the decline certain height, to reduce the wind area of topgallant 13, topmast 14 and lower mast 15, to improve the stability of boats and ships.
As Fig. 4, shown in Figure 5, during when ship entry or through narrow bay or navigation channel, two collaborative relative positions of adjusting of auxilliary ship, the arranged distribution of straight line before and after forming, make the coincides of three ship upper bodies, form a long and narrow ship upper body, reduce the horizontal space at shared navigation channel or harbour, so that open the navigation or air flight smoothly and berth.When wind direction and course were not inconsistent, two auxilliary ships will be according to instruction, collaborative adjustment orientation separately, and accurate the transformation takes place in the angle of facining the wind of traction solar wind sail, even boats and ships under the situation of side headwind, still can move ahead smoothly.At this moment, because the side direction wind action also is subjected to horizontal thrust when boats and ships move ahead.In order to reduce the ship upper body horizontal skew takes place, this moment, dagger plate 16 fell the insertion water from the both sides of main ship upper body 1, to increase the resistance of lateral excursion.The onward impulse of trimaran only comes from the electric propulsion device of main ship.The weight of solar wind sail is born in the operation of the just collaborative main ship of the electric propulsion device of two auxilliary ships, and the frontal resistance that overcomes sail.The electric propulsion device of auxilliary ship is not born and is driven the function that trimaran advances.
