One ends of the three parallel first return spring double-acting oil cylinders 6 are hinged to the lower side of the front side body connecting piece 2a, and the other ends of the three parallel first return spring double-acting oil cylinders are hinged to the inner side of the front side body vertical section 2 c; one end of each of the three second return spring double-acting oil cylinders 6a which are parallel is hinged with the lower side of the rear side body connecting piece 3a, and the other end of each of the three second return spring double-acting oil cylinders is hinged with the inner side of the rear side body vertical section 3 c.
Fig. 7, 8 and 9 are working schematic diagrams of a hydraulic system, and a hydraulic power generation mechanism comprises two groups of first return spring double-acting oil cylinders 6, two groups of second return spring double-acting oil cylinders 6a, a pressure accumulation tank 11, a circulating oil tank 12 and a third power generator 13 driven by a hydraulic motor 12; when the hydraulic motor works, an oil inlet cavity of the return spring double-acting oil cylinder is connected with the circulating oil tank 12 through an oil return one-way valve by adopting a hose, an oil outlet cavity is connected with the pressure accumulation tank 11 through an oil supply one-way valve by adopting a hose, and the pressure accumulation tank 11 is connected with the hydraulic motor 12 through a pipeline.
In the normal working process, the return spring double-acting oil cylinder can exchange energy with the energy accumulator, and hydraulic oil can drive the third generator 13 to generate electricity through the hydraulic motor. As shown in fig. 8, when the return spring double-acting cylinder is stretched, an upper oil inlet and lower oil pressing mode is adopted, the return spring double-acting cylinder is stretched, and oil at the lower end of the return spring double-acting cylinder is conveyed to the pressure accumulation tank 11 through a first oil supply one-way valve V1; the high-pressure oil in the pressure accumulation tank 11 drives the hydraulic motor 12 to drive the third generator 13 to generate electricity, the hydraulic oil from the hydraulic motor 12 is conveyed into the circulating oil tank 14, the circulating oil tank 14 conveys the oil back to the upper end of the return spring double-acting oil cylinder through the second oil return one-way valve V4, and an upper oil inlet mode and a lower oil pressing mode are completed. As shown in fig. 9, when the return spring double-acting cylinder is compressed, a lower oil inlet and upper oil pressing mode is adopted, the return spring double-acting cylinder compresses, oil at the upper end of the return spring double-acting cylinder is conveyed to the pressure accumulation tank 11 through the second oil supply one-way valve V2, high-pressure oil in the pressure accumulation tank 11 drives the hydraulic motor 12 to drive the third generator 13 to generate electricity, hydraulic oil from the hydraulic motor 12 is conveyed to the circulating oil tank 14, and the circulating oil tank 14 conveys the oil back to the lower end of the return spring double-acting cylinder through the first oil return one-way valve V3, so that the lower oil inlet and upper oil pressing mode is completed.
The return spring double-acting oil cylinder with the suspension function can limit the movement of the side bodies, so that the lifting force provided by the four side bodies is enough to maintain the stability of the main body. When the ship moves at high speed, the side bodies generate alternate heave motion relative to the main body due to the influence of wave load. The side body generator 7 can continuously absorb the kinetic energy of the side body movement to generate power for the ship, and can further limit the side body movement.
The side body generator set is installed on the inner side of the main body and connected with the connecting shaft, and the directions of hydrodynamic loads acting on the side body submerged body in waves can be alternated up and down, so that alternating heaving force acting on the submerged body is generated, heaving motion of the submerged body relative to the main ship body is induced, and the relative motion is converted into electric energy through the shipborne power generation device. As shown in fig. 6, when the front body 2 and the rear body 3 disposed on one side of the ship body are subjected to an upward heave force, the front body 2 and the rear body 3 simultaneously drive the connecting shaft 5 to rotate, and further the forward bevel gear 7a locked on the connecting shaft 5 by the ratchet 5a rotates (the reverse bevel gear 7b cannot be locked with the connecting shaft 5 by another ratchet), and the forward bevel gear 7a rotates to drive the main cylindrical gear 7c to rotate, so that the inertia wheel 7f is accelerated to rotate, and the output voltages of the first generator 7e and the second generator 7e1 can be ensured to be more stable; when the front body 2 and the rear body 3 are subjected to downward heave force, the reverse bevel gear 7b locked on the connecting shaft 5 drives the main cylindrical gear 7c to rotate (the forward bevel gear 7a cannot be locked with the connecting shaft 5 through the ratchet wheel 5 a) because the reverse bevel gear 7b is provided with another ratchet wheel. When the front side body 2 and the rear side body 3 arranged at the other side of the ship body are subjected to upward and downward heave forces, the operation process of the side body generator 7 is the same as that of the prior art.
The four-body ship structure has strong wave resistance and stability, and can generate clean energy through the movement of the side bodies. Because the ship-shaped structure provides buoyancy through the submerged bodies below the four side bodies, the waterline area is small, so that the ship-shaped structure is less influenced by waves under high-speed running or high sea conditions and has stronger wave resistance; as can be seen from the figure 2, the distance between the front side bodies is obviously smaller than that between the rear side bodies, and the propeller is arranged at the tail part of the front side body floating body, so that the wave making resistance of the ship body can be reduced, and the energy conservation and the rapidity of the ship are improved.
