Because one end and the cylindrical floating drum of lever is rigid connection, cylindrical floating drum is done vertical to-and-fro motion in company with ocean wave, so just drives lever to take fixed rotating shaft as fulcrum moves back and forth, and drives the piston rod movement being attached thereto; By hydraulic reciprocating mechanism, can drive mover to-and-fro motion to generate electricity.In when design, allow and by sliding shaft, be connected between lever and piston rod, be skew or the inclination for fear of piston rod generation Vertical direction, cause the loss of whole hydraulic reciprocating mechanism, to extend whole working life.
Preferably, described stator tubular, mover is placed in stator, and stator interior is divided into two cavitys in left and right, is designated as respectively left cavity and right cavity; Piston ring is divided into upper and lower two cavitys by piston/cylinder inside, is designated as respectively upper cavity and lower chamber; Lower chamber oil inlet and outlet is connected with left cavity oil inlet and outlet by A two-way valve, and right cavity oil inlet and outlet is connected with upper cavity oil inlet and outlet by bidirectional traffics control valve, B two-way valve; Hydraulic oil is placed in cavity volume, lower cavity volume, left cavity, right cavity and connecting tube.
Because driving piston ring, piston rod moves back and forth up and down, hydraulic oil in upper cavity and lower chamber is shifted, just planting to shift also shifts the left cavity that is communicated with it and the hydraulic oil in right cavity, so just driven mover, mover is moved with respect to stator, the magnetic induction line of permanent magnet (mover) itself can be cut by coil winding (stator), according to Faraday law of electromagnetic induction, coil winding (stator) will induce voltage, thereby makes linear electric motor mechanism reach the effect of generator operation.
When design oil circuit, increased bidirectional traffics control valve, to guarantee the constant flow rate of hydraulic oil when through two-way bidirectional traffics control valve; So also just make the constant airspeed of mover when to-and-fro motion, and then make the output power of linear electric motor mechanism keep constant.Because the electric energy of linear electric motor mechanism output can not, directly to the power supply of hull consumer, so first linear electric motor mechanism need to charge through charging unit phase energy storage device, then be powered to hull consumer by energy storage device.
Preferably, on piston rod, be provided with limiting stopper, in power generation box, be provided with positioning block, by the top board of positioning block and power generation box, limit the moving range of limiting stopper; Simultaneously at piston rod, be arranged with spring, the two ends of the end face restraining spring by limiting stopper and piston/cylinder.In the phugoid motion process of ocean wave, when near the ocean wave cylindrical floating drum moves to trough, according to lever principle, piston ring can be driven and then be moved upward by piston rod, and the effect of spring is to guarantee that piston ring can move to rapidly the upper end portion of piston/cylinder; The effect of positioning block and limiting stopper is that the displacement range of piston ring is limited in a certain scope.
Preferably, during hydrostatic, lever positions level.
Preferably, during hydrostatic, the draft of cylindrical floating drum is half of its height, and object is to reduce the center of gravity of cylindrical floating drum, and then guarantees the stability of cylindrical floating drum in vertical to-and-fro motion process.
In the present invention, power generation box can be arranged on the two sides of tail of hull, also can be arranged on the afterbody neutral position of hull, and the number of the power generation box specifically needing, can determine according to the actual conditions of hull.
Beneficial effect: the ocean wave power generation device peculiar to vessel of constant power output provided by the invention, by lever principle, hydraulic driving and cylinder type permanent magnet linear generator, directly ocean wave energy is converted to electric energy, owing to not relating to the link of indirect transfer in conversion process of energy, so the constant power output ocean wave power generation device assembly structure that the present invention utilizes hull and cylindrical orthogonal floating drum to generate electricity is simple, efficiency is high, can be widely to the consumer on hull, provide electric energy to supply with.
