Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. The technical means used in the examples are conventional means well known to those skilled in the art unless otherwise indicated.
In the description of the present invention, it should be understood that the terms "longitudinal," "transverse," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like indicate or are based on the orientation or positional relationship shown in the drawings, merely to facilitate description of the present invention, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus should not be construed as limiting the present invention.
As shown in fig. 1-8, the invention discloses a wave energy floating power generation device, which comprises a plurality of floating power generation mechanisms which are movably connected, wherein each floating power generation mechanism comprises a driving component and a power generation component, and the driving component inclines left and right under the action of wave energy to drive the power generation component to work so as to realize the purpose of wave energy power generation. The driving assembly comprises a floating plate 1 and a vertical plate 2 connected with the floating plate 1, wherein a first channel in the horizontal direction is arranged on the floating plate 1, a sliding block 3 with a certain mass is arranged in the first channel in a sliding manner, a second channel 9 which is communicated with the first channel and is in the vertical direction is arranged in the vertical plate 2, a piston block 7 is arranged in the second channel 9 in a sliding manner, and the other end, far away from the first channel, of the piston block 7 is provided with a power generation assembly; the first and second channels 9 are filled with liquid between the slide block 3 and the piston block 7.
The first channel and the second channel 9 are disposed perpendicularly to each other to form an "L" channel. The slider 3 has a certain mass. The shape and size of the sliding block 3 correspond to the cross-sectional shape and size of the first channel, so that when the sliding block 3 slides in the first channel, liquid can be pushed to move in the first channel. The shape and size of the piston block 7 correspond to the shape and size of the cross section of the second channel 9, so that liquid at the lower end of the piston block 7 cannot enter the upper end of the piston block 7, and when the liquid moves upwards in the second channel 9, the piston block 7 is pushed to slide upwards in the second channel 9.
The liquid may be hydraulic oil, or may be water, preferably hydraulic oil. A first limiting block 36 is arranged in the second channel 9 and at the connecting part with the first channel, and the first limiting block 36 limits the piston block 7 from falling into the first channel from the second channel 9.
As shown in fig. 1, the floating plate 1 inclines left along with the wave, because the sliding block 3 has a certain mass, the sliding block 3 slides to the lower end (the left end in the first channel) in the first channel due to self gravity, liquid is extruded, the liquid flows into the second channel 9 from the first channel, the piston block 7 moves upwards in the second channel 9, and the working end of the power generation assembly is driven to move upwards in the second channel 9. The floating plate 1 inclines to the right along with the wave, the sliding block 3 slides to the right from the left end in the first channel due to self gravity, liquid flows back into the first channel from the second channel 9, the piston block 7 in the second channel 9 moves downwards in the second channel 9 due to self gravity, and returns to the lowest point in the second channel 9. The floating plate 1 inclines left and right along with the wave energy in such a way, and the working end of the power generation assembly continuously moves up and down in the second channel 9 due to the cooperation of the sliding block 3, the liquid and the piston block 7, so that the purpose of wave energy power generation is realized.
Further, as shown in fig. 1-3, in order to fully utilize wave energy, two risers 2 are symmetrically disposed on the upper surface of the floating plate 1, two second channels 9 are disposed in the two risers 2, two first channels corresponding to the two risers 2 are mutually communicated, the two communicated first channels form a fourth channel 6 in the horizontal direction, and two ends of the fourth channel 6 are communicated with the second channels 9 to form an inverted channel. The fourth channel 6 is filled with liquid, and the two sides of the sliding block 3 and the two piston blocks 7 are respectively filled with liquid. When the floating plate 1 is in a horizontal state, the sliding block 3 is positioned in the middle of the fourth channel 6, the liquid is completely positioned in the fourth channel 6, no liquid exists in the second channel 9, i.e. the piston block 7 is positioned at the lowest point in the second channel 9, as shown in fig. 1.
When the floating plate 1 is changed from a leftward inclined state to a rightward inclined state, the sliding block 3 slides from the left end to the right end in the fourth channel 6 due to self gravity, liquid on the left side of the sliding block 3 flows back into the first fourth channel from the second channel 9, the piston block 7 in the second channel 9 on the left side moves downwards in the second channel 9 due to self gravity, returns to the lowest point in the second channel 9, and drives the working end of the power generation assembly on the left side to move downwards in the second channel 9. Due to the dead weight of the sliding block 3, the liquid on the right side of the sliding block 3 flows into the second channel 9 on the right side from the fourth channel 6, and the piston block 7 moves upwards in the second channel 9 on the right side, so that the working end of the power generation assembly on the right side is driven to move upwards in the second channel 9. Therefore, the floating plate 1 inclines left and right along with waves, the power generation assemblies on the left side and the right side work simultaneously, and wave energy can be utilized.
Further, in order to make the sliding block 3 slide left and right in the fourth channel 6 more easily, an auxiliary component is disposed above the floating plate 1, and the auxiliary component helps the sliding block 3 slide in the fourth channel 6. The auxiliary assembly comprises an arc-shaped connecting plate 16 connected with the top ends of the two vertical plates 2, an arc-shaped chute 17 is arranged at the lower end of the arc-shaped connecting plate 16 along the length direction of the arc edge, and an auxiliary weight 18 is arranged on the chute 17 in a sliding manner. When the floating plate 1 is in a horizontal state, the auxiliary weight 18 is positioned at the highest point of the arc edge of the arc connecting plate 16. Under the condition of the scheme, in order to prevent the floating plate 1 from overturning, the floating plate 1 can be made larger as much as possible. When the floating plate 1 tilts to the left along with the wave, the auxiliary weight 18 slides to the left in the arc chute 17, so that the floating plate 1 tilts to the left to a larger extent, and the left piston block 7 moves upward in the second channel 9 to a larger distance. Similarly, when the floating plate 1 tilts to the right along with the wave, the auxiliary weight 18 slides to the right in the arc chute 17, so that the floating plate 1 tilts to the right to a larger extent, and the right piston block 7 moves upward in the second channel 9 to a larger distance.
Further, a first cavity for accommodating the fixed cable 19 is arranged in the arc-shaped connecting plate 16 along the length direction of the arc edge, one end of the cable 19 is connected with the power generation assembly, and the other end of the cable 19 is connected with a container for storing electric energy. The container for storing electric energy can be a rechargeable battery 20, and the battery 20 can be detachably arranged inside the arc-shaped connecting plate 16, so that the battery is prevented from being directly exposed to air.
