Ocean kinetic energy includes tidal energy, wave energy, and the like. In order to utilize this enormous ocean kinetic energy, the laws of tidal energy and wave energy have been studied and utilized separately.
At present, tidal power generation is mainly realized by intercepting seawater in the rising tide through a rising and repairing reservoir and pushing a water turbine to operate by utilizing the height difference of the water surface in the falling tide so as to convert water head potential energy into electric energy. In order to generate power by matching with the characteristics of low water head and large flow of tide, a large water wheel is mainly adopted for operation at present, but the requirements on the processing and manufacturing process are correspondingly higher, the structure is complex, the rotational inertia is large, the energy conversion efficiency is low, and the manufacturing cost and the power generation cost of matched facilities are also greatly improved.

A first water generating wheel 123 is also arranged in the second cavity 122.
Illustratively, when the sea level rises at the time of rising tide, the first movable rod 13 makes the first piston 131 rise along the inner wall of the first cavity 121 under the buoyancy of the floating plate 3, so that the inner cavity volume of the first cavity 121 is increased, and the seawater outside the first housing 12 enters the first cavity 121 from the second cavity 122.

The second power generation assembly 2 includes a telescopic baffle 21, a second movable bar 22, a second housing 23 and a third housing 24, as shown in fig. 4 for example.

Preferably, the buoyancy provided by the floating plate 3 can enable the telescopic baffle 21 and the upper half part of the second movable rod 22 to be positioned outside water by adjusting the size of the floating plate 3, so that the collection rate of the power generation device on waves is improved, and the power generation efficiency is improved.
The interior of the second housing 23 is provided with a third cavity 231, as shown, for example, in fig. 5.
A second piston 221 is further fixedly mounted at one end of the second movable rod 22 located in the third cavity 231, and the second piston 221 is movably clamped in the third cavity 231 and is arranged at the joint of the third cavity 231 in a sliding and sealing manner. A first spring 232 is further disposed in the third cavity 231, and the second piston 221 is elastically connected to a side plate of the second housing 23, which faces the second piston 221, through the first spring 232.
Preferably, the first spring 232 may be a piezoelectric spring, and can generate electricity while extending and contracting, collect the generated electricity, and improve the power generation efficiency of the power generation device.
A first through hole 233 is further formed in a side plate of the second housing 23 opposite to the second piston 221, a second fixture block 234 is movably clamped in the first through hole 233, and the second fixture block 234 is elastically connected with an outer wall of the side plate of the second housing 23 through a second spring 235.

One end of the third latch 237 located inside the second housing 23 can be covered on the second through hole 236.
For example, when the wave pushes the telescopic baffle 21 to move away from the second housing 23, the second piston 221 moves away from the first through hole 233, so that the volume in the third cavity 231 increases, and at this time, the seawater can push the third latch 237 from the second through hole 236 and enter the third cavity 231; while the first spring 232 is extended by the tensile force of the second piston 221.
When the wave pushes the retractable barrier 21 to move in a direction approaching the second housing 23, the first spring 232 contracts, so that the second piston 221 approaches the first through hole 233, and the volume in the third cavity 231 decreases, at this time, the seawater in the third cavity 231 moves towards the first through hole 233 under the pushing of the second piston 221, and pushes the second fixture block 234 to flow out of the first through hole 233 to the outside of the second housing 23.
Illustratively, the telescopic baffles 21 comprise a plurality of groups, the telescopic baffles 21 are installed at one end of the second movable rod 22, and the telescopic baffles 21 are driven by a hydraulic drive or an electric telescopic rod; when the telescopic shutter 21 is completely retracted, the outer side edge of the telescopic shutter 21 is flush with the outer side edge of the second movable bar 22.

When the sea condition forecast information or the waves detected by the wave detector are normal conditions, the control system controls the telescopic length of the telescopic baffle 21 according to the wave height, and when the waves impact, the telescopic baffle 21 extends out of the second movable rod 22 to be capable of contacting the waves to a greater extent, so that the impact of the waves is borne more, the collection rate of the power generation device on the wave energy is improved, and the power generation efficiency is improved.
Because the wave detector and the sea condition information forecasting receiver are arranged at the same time, the sea condition can be pre-judged in advance according to the sea condition forecasting information, the control system sends out an adjusting instruction, and the adjusting angle of the rotary circular table 14 and the extending length of the telescopic baffle 21 are further corrected according to the real-time sea condition detected by the wave detector, so that the wave energy collecting device is better adapted to the real-time sea condition, and the wave energy collecting rate and the safety of the power generation device can be further improved.
The third housing 24 is provided with a fourth cavity 241 and a fifth cavity 243 therein, as shown in fig. 6 for example.
The fourth cavity 241 is in communication with the second through hole 236; a second water turbine 242 is rotatably installed in the fourth cavity 241.

a third through hole 245 is further formed in the third shell 24, the third through hole 245 is communicated with the fifth cavity 243, and the third through hole 245 is used for discharging seawater in the fifth cavity 243.
Illustratively, when the wave pushes the telescopic baffle 21 to move away from the second housing 23, the second piston 221 moves away from the first through hole 233, so that the volume in the third cavity 231 increases, and at this time, the seawater moves from the fourth cavity 241 to the second through hole 236, and pushes the third block 237 and enters the third cavity 231; during this period, the seawater entering the third cavity 231 from the fourth cavity 241 pushes the second water turbine 242 to rotate, thereby generating electric energy. While the first spring 232 is extended by the tensile force of the second piston 221.
When waves push the telescopic baffle plate 21 to move towards the direction close to the second shell 23, the first spring 232 contracts, so that the second piston 221 is close to the first through hole 233, the volume in the third cavity 231 is reduced, at this time, seawater in the third cavity 231 moves towards the first through hole 233 under the push of the second piston 221, and pushes the second fixture block 234 to enter the fifth cavity 243 and flow out of the third through hole 245 to the outside of the second shell 23, and during the period, the seawater entering the fifth cavity 243 from the third cavity 231 pushes the third power generation water wheel 244 to rotate, so that the device can more effectively utilize the wave energy to generate electric energy.
The tidal energy and wave energy combined power generation device provided by the embodiment of the invention has the following working principle:
when the sea level rises due to rising tide, the first movable rod 13 makes the first piston 131 rise along the inner wall of the first cavity 121 under the buoyancy of the floating plate 3, so that the inner cavity volume of the first cavity 121 is increased, and the seawater outside the first housing 12 enters the first cavity 121 from the second cavity 122. During this period, the seawater entering the first cavity 121 from the second cavity 122 pushes the first power generation turbine 123, so that the first power generation turbine 123 rotates to generate electric power.
When the tide is ebb, the sea level descends, and the floating plate 3 descends along with the descent of the sea level, so that the first piston 131 of the first movable rod 13 descends along the inner wall of the first cavity 121, the inner cavity volume of the first cavity 121 is reduced, and the seawater in the first cavity 121 is discharged from the second cavity 122 to the outside of the first housing 12. During this period, the seawater flowing out of the second cavity 122 to the outside of the first housing 12 pushes the first power generation pulley 123, so that the first power generation pulley 123 rotates to generate electric power.
When the wave pushes the telescopic baffle 21 to move in the direction away from the second housing 23, the second piston 221 moves away from the first through hole 233, so that the volume in the third cavity 231 increases, and at this time, the seawater moves from the fourth cavity 241 to the second through hole 236, and pushes the third block 237 and enters the third cavity 231; during this period, the seawater entering the third cavity 231 from the fourth cavity 241 pushes the second water turbine 242 to rotate, thereby generating electric energy. While the first spring 232 is extended by the tensile force of the second piston 221.
When waves push the telescopic baffle plate 21 to move towards the direction close to the second shell 23, the first spring 232 contracts, so that the second piston 221 is close to the first through hole 233, the volume in the third cavity 231 is reduced, at this time, seawater in the third cavity 231 moves towards the first through hole 233 under the push of the second piston 221, and pushes the second fixture block 234 to enter the fifth cavity 243 and flow out of the third through hole 245 to the outside of the second shell 23, and during the period, the seawater entering the fifth cavity 243 from the third cavity 231 pushes the third power generation water wheel 244 to rotate, so that the device can more effectively utilize the wave energy to generate electric energy.
Through setting up first power generation subassembly 1 and second power generation subassembly 2 for the device both can generate electricity when rising tide or ebb tide, can utilize the wave energy to generate electricity in the time quantum outside the tide again, need not to build large-scale supporting setting, and the installation is more nimble.
The state of the telescopic baffle 21 is adjusted by controlling the hydraulic driving mechanism or the electric telescopic rod through the control system, when the sea condition forecast information or the waves detected by the wave detector are extreme sea conditions, the telescopic baffle 21 is retracted, the outer edge of the telescopic baffle 21 is flush with the outer edge of the second movable rod 22, and the situation that the protruded telescopic baffle 21 is damaged by sea waves or the structure and the motor equipment of the power generation device are damaged by overlarge impact force on the telescopic baffle 21 is avoided. When the sea condition forecast information or the waves detected by the wave detector are normal conditions, the control system controls the telescopic length of the telescopic baffle 21 according to the wave height, and when the waves impact, the telescopic baffle 21 extends out of the second movable rod 22 to be capable of contacting the waves to a greater extent, so that the impact of the waves is borne more, the collection rate of the power generation device on the wave energy is improved, and the power generation efficiency is improved.
The angle of the first connecting plate 11 and the second power generation assembly 2 on the first connecting plate is adjusted by the control system to control the rotary circular truncated cone 14, and the included angle between the telescopic baffle 21 and the wave is adjusted, so that the wave vertically impacts on the surface of the telescopic baffle 21, the power generation efficiency is improved, the included angle formed between the wave and the second power generation assembly 2 is avoided, the invalid impact of the wave on the second power generation assembly 2 is reduced, the damage of the wave to the power generation assembly is reduced, and the service life and the safety of the power generation device can be greatly improved.
