Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail below with reference to the accompanying drawings and examples.
A piezoelectric power generating apparatus for a side shell plate using rolling of a ship, as shown in fig. 1, 2, 3, 4 and 5, comprising: the piezoelectric hinge comprises a fixed hinge support 1, an elastic material 2, a pressing plate 3, a cushion block 4, a piezoelectric material 5 and a return spring 6.
As shown in fig. 1, grooves are formed in positions of the topsides on two sides of the ship body at the beginning of the design of the ship, the lower edges of the grooves are located on a waterline, the grooves are formed by inward deformation of the side planks of the topsides, the side planks in the grooves are actually ship body steel plates, and the formed grooves do not damage the overall structural strength of the ship body. A plurality of groups of the device can be arranged along the ship length direction, two fixed hinge supports 1 are required in one group of the device, and the two fixed hinge supports are respectively fixed at the tops of the grooves; the pressing plate 3 is arranged in the groove, a rotating shaft is arranged on the pressing plate 3, two ends of the rotating shaft of the pressing plate 3 are respectively matched with the two fixed hinge supports, and the distance between every two adjacent pressing plates is 2-4 mm.
As shown in fig. 2, 3 and 4, the piezoelectric material 5 is attached to the ship body steel plate in the groove, and the deformation amount of the piezoelectric material 5 when generating voltage is 2-4 mm; the cushion block 4 is arranged between the pressure plate 3 and the piezoelectric material 5 and fixed in the middle of the pressure plate 3, and the contact area of the cushion block 4 is far smaller than that of the pressure plate 3, so that the pressure plate 3 can transmit larger pressure to the piezoelectric material 5 through the cushion block 4; the reset spring 6 is located at the bottom of the groove, two ends of the reset spring 6 are respectively fixed on the piezoelectric material 5 and the pressing plate 3, and the deformation amount of the piezoelectric material 5 when generating voltage is small, so that the contraction deformation amount of the reset spring 6 is small in the process that the piezoelectric material 5 is extruded and deformed.
As shown in fig. 5, the elastic material 2 completely covers the groove area preset on the ship body freeboard, and the elastic material 2 has certain elasticity, is in watertight fit with the edge of the groove, forms a sealed space with the groove, and prevents seawater from entering the groove. The length of the freeboard part above the waterline of the ship body along the ship length direction is very long, and the freeboard is high in height, so that when the ship is subjected to rolling motion under the action of wind and waves in the sailing process, the area of the freeboard part immersed in seawater is very large, and the pressure of the seawater on the freeboard is very large.
When a ship inclines leftwards during sailing, as shown in fig. 6, the topside of the ship body on the left side can be immersed in water, the elastic material 2 on the topside on the left side can be deformed under the pressure of the water, the elastic material 2 can generate a certain acting force on the pressing plate 3 under the action of the water pressure, the pressing plate 3 can rotate around the fixed hinged support 1, and then the pressing plate generates pressure on the piezoelectric material 5 through the cushion block 4, so that the piezoelectric material 5 generates power, and at the moment, the reset spring 6 is in a contraction state. When the ship is switched from a left inclined to a right inclined state, the elastic material 2 on the freeboard on the left side of the ship body is not squeezed by water, and the return spring 6 is restored to the initial state.
When a ship inclines rightwards during sailing, as shown in fig. 7, the topside of the right side of the ship body is immersed in water, the elastic material 2 on the topside of the right side is deformed under the action of water pressure, the elastic material 2 generates a certain acting force on the pressing plate 3 under the action of water pressure, the pressing plate 3 rotates around the fixed hinged support 1, and then generates pressure on the piezoelectric material 5 through the cushion block 4, so that the piezoelectric material 5 generates electricity, and at the moment, the reset spring 6 is in a contraction state. When the ship is switched from right inclination to left inclination, the elastic material 2 on the starboard of the right side of the ship body is not extruded by water, and at the moment, the return spring 6 is restored to the initial state again.
In fact, when the ship generates rolling motion during sailing, the left inclination and the right inclination of the ship are continuously and alternately performed, so the device can continuously generate power when the ship moves in rolling.
When the rolling motion takes place in the boats and ships navigation process, boats and ships left and right sides topside part can be in turn submerged, and at this moment, elastic material 2's sunken can produce certain effort to clamp plate 3, and clamp plate 3 can take place to rotate and then produce pressure to piezoelectric material 5 through cushion 4 around fixed hinged-support 1 to make piezoelectric material 5 generate electricity, but piezoelectric material 5's deflection is very little, so elastic material 2 also can not have obvious deformation. As shown in fig. 8, the degree of concavity of the elastic material 2 when deformed by water pressure is the same along the length direction of the ship, and the ship body still keeps very streamline along the length direction, and does not cause extra sailing resistance to the ship, because:
one is as follows: since the amount of deformation of the piezoelectric material 5 is 2 to 4mm, a 2 to 4mm depression is generated in the hull by the action of water pressure when the elastic material 2 is immersed in water, and therefore the amount of deformation of the elastic material 2 in the ship length direction is small. The second step is as follows: because the distance between two adjacent clamp plates is 2 ~ 4mm, the clearance between two clamp plates is very little, so elastic material 2 can not imbed in two adjacent clamp plates when receiving hydraulic deformation, consequently the sunken degree of elastic material 2 when receiving hydraulic deformation is the same along the captain direction, and the hull still keeps very good streamlined along the captain direction, can not cause extra navigation resistance for boats and ships. In conclusion, the ship provided with the device of the invention does not generate additional resistance when rolling motion occurs during sailing.
The invention is characterized in that the groove is arranged on the topsides of the ship body, the topsides part above the waterline of the ship is very long along the length direction of the ship, so that a plurality of devices can be arranged in the groove, when the ship is subjected to rolling motion under the action of wind and waves in the sailing process, the area of the topsides part immersed in seawater is very large, the pressure of the seawater on the topsides is very large, and the recoverable energy of the invention is very large, and the power generation effect is good.
The device is applied to sailing ships, rolling motion of the ships is caused by the action of waves, power generation of the piezoelectric material 5 is realized by using water pressure, wave energy is substantially and indirectly utilized, and the problem that the sailing ships effectively utilize wave energy is solved. The invention is mainly used for ships with the weight of less than 10 ten thousand tons, and the rolling motion of the ships is most obvious, so the power generation effect of the device is obvious.
