Description

Technical Field

[0001] The present invention relates to the field of tidal power generation, and particularly to a wave and tidal energy power generation device combined with a caisson seawall. Background Art

[0002] As is well known, tidal power generation is a renewable energy technology that utilizes the movement of ocean tides to generate electricity. Tides are the periodic rise and fall of seawater caused by the gravitational forces of the moon and the sun and the rotation of the earth. Tidal power generation utilizes this natural phenomenon and converts the kinetic energy and potential energy of the tide into electrical energy through specific equipment;

[0003] For example, the authorized announcement number is CN104564508B, the authorized announcement date is July 21, 2017, and the name is a tidal power generation device, which includes a first energy conversion device, a second energy conversion device, a third energy conversion device connected in sequence, and a fluid control device connected between the second energy conversion device and the third energy conversion device. The fluid control device is used to provide continuous and stable seawater fluid energy to the third energy conversion device. The tidal power generation device of the present invention provides continuous and stable fluid energy to the third energy conversion device through the setting of the fluid control device for continuous and stable power generation...;

[0045] Embodiment 1

[0046] Refer to Figure 1 - Figure 5 : This embodiment provides a technical solution: a wave and tidal energy power generation device combined with a caisson-type seawall, including a box body 1, a wave power generation system, and a tidal power generation system. The box body 1 is arranged in a geographical environment where tides can occur. The wave power generation system is arranged outside the box body 1 and is used for generating electricity through waves. The tidal power generation system is arranged inside the box body 1 and is used for generating electricity through the inflow and outflow of water inside the box body 1. The wave power generation system includes a self-adjusting lifting base plate 306 and a rocking plate power generation unit. The self-adjusting lifting base plate 306 can automatically adjust its position based on the water surface height. The rocking plate power generation unit is installed on the self-adjusting lifting base plate 306 and is used for generating electricity through waves.

[0047] By adopting the above technical solution: the device is applied to a geographical environment that can generate tides. When in use, the tidal power generation system and the wave power generation system can jointly perform power generation operations, thereby achieving a dual power generation effect, high power generation efficiency, and higher tidal utilization. The rocking plate power generation unit in the wave power generation system is installed on a self-adjusting lifting base plate 306, and the self-adjusting lifting base plate 306 can automatically adjust its position based on the water surface height. Therefore, the rocking plate power generation unit can always be in a suitable position for power generation during high tide and low tide, thereby improving the utilization rate of the tide and thereby achieving a qualitative improvement in power generation.

[0048] Specifically, Figure 1 - Figure 9 As shown, in order to generate wave power by the rocking plate power generation unit, in this embodiment, the rocking plate power generation unit includes a protrusion 305, a rocking plate 300 and a rocking plate power generation unit. The protrusion 305 is fixed to the outer side of the self-adjusting lifting base plate 306, and a rocking shaft 315 is installed on the protrusion 305. The rocking plate 300 is arranged on one side of the self-adjusting lifting base plate 306 and is fixedly installed on the rocking shaft 315 through a connecting portion 316. A rocking buoy 301 is provided at the front end of the rocking plate 300. The rocking plate power generation unit is installed on the self-adjusting lifting base plate 306 for conducting and converting the mechanical energy generated by the rocking plate 300 into electrical energy to realize wave power generation. Since the rocking buoy 301 floats on the water surface, it can float up and down with the ups and downs of the waves on the water surface, thereby driving the rocking shaft 315 to swing and generate mechanical energy, and then the mechanical energy generated by the swing is conducted and converted into electrical energy through the rocking plate power generation unit to generate electricity.

[0049] Specifically, Figure 5 - Figure 9 As shown, in order to realize the conversion of mechanical energy generated by the swing of the rocking plate 300 into electrical energy, in this embodiment, the rocking plate power generation unit includes an arc cylinder 322, a swing power generation box 309 and a straight cylinder 323, wherein the arc cylinder 322 is installed on the self-adjusting lifting base plate 306, and an active piston 320 is installed inside the arc cylinder 322. One side of the active piston 320 is connected to the bottom surface of the rocking plate 300 through an arc rod 321, so that when the rocking plate 300 is swinging, it can drive the active piston 320 to move in the arc cylinder 322, and the swing power generation box 309 is installed on the self-adjusting lifting base plate 306. On the lowering base plate 306, a third generator set 313 is installed inside the swing power generation box 309, the rotating shaft of the third generator set 313 extends into the swing power generation box 309 and is connected to the turntable 308, an eccentric shaft 310 is installed on the outer side of the turntable 308, a straight cylinder 323 is installed in the swing power generation box 309, the bottom of the straight cylinder 323 is connected to the arc cylinder 322, a passive piston 319 is arranged inside the straight cylinder 323, a piston rod 318 is connected to the outer side of the passive piston 319, and the top of the piston rod 318 is transmission-connected to the eccentric shaft 310 on the turntable 308 through a connecting rod 317;

[0050] Power generation principle: When the swing float 301 at the front end of the swing plate 300 floats up and down driven by the waves, it drives the swing plate 300 to rotate around the swing axis 315. The swing plate 300 drives the active piston 320 to reciprocate in the arc-shaped cylinder 322 through the arc-shaped rod 321. Under the action of air pressure, it drives the passive piston 319 to reciprocate in the straight cylinder 323. The passive piston 319 drives the turntable 308 to rotate through the connecting rod 317 and the piston rod 318, and then transmits the mechanical energy to the third generator set 313 for power generation.

[0051] It should be noted that: in order to avoid the situation that it is difficult to provide enough stroke to support the rotation of the turntable 308 when the wave undulation is small, the inner diameter of the straight cylinder 323 is smaller than that of the arc-shaped cylinder 322. Therefore, the moving stroke of the passive piston 319 is greater than that of the active piston 320, so that even when the wave undulation amplitude is small, it can still support the rotation of the turntable 308. In addition, when the undulation is too large, the passive piston 319 moves to the limit position (when the eccentric shaft 310 is at the farthest position from the straight cylinder 323, it will not move further), so it will not affect the rotation of the turntable 308.

[0052] Specifically, as Figure 5 - Figure 7 shown, in order to ensure that the swing plate power generation unit can stably perform power generation operations, in this embodiment, the centers of the arc-shaped cylinder 322 and the arc-shaped rod 321 coincide with the axis of the swing axis 315, ensuring that the swing plate 300 will not get stuck when rotating.

[0053] Specifically, as Figure 5 - Figure 7 shown, in order to enable the self-adjusting lifting substrate 306 to move in the vertical direction, in this embodiment, buckling guide seats 304 are installed on both sides of the self-adjusting lifting substrate 306, and a gantry 303 is installed on the front side of the box body 1. The gantry 303 adopts an inverted U-shaped structure, and guide rails 302 are installed on the inner sides of the two vertical ends of the gantry 303. The buckling guide seats 304 on both sides of the self-adjusting lifting substrate 306 are respectively slidably clamped on the two guide rails 302, enabling the self-adjusting lifting substrate 306 to slide vertically between the two guide rails 302.

[0054] Specifically, as Figure 5 - Figure 7 shown, in order to enable the self-adjusting lifting substrate 306 to automatically adjust its position based on the water surface height and without the need for power control to achieve an energy-saving effect, in this embodiment, an adjusting float 307 is installed on the self-adjusting lifting substrate 306, and the adjusting float 307 can drive the self-adjusting lifting substrate 306 to float on the water surface.

[0055] Specifically, as Figure 5 - Figure 7As shown in the figure, in order to prevent the entire self - adjusting lifting substrate 306 from floating following the undulation of the waves under the action of the adjusting floating body 307, which may affect the swing of the rocker plate 300 and reduce the power generation efficiency, in this embodiment, a positioning tooth groove 3020 is provided vertically along the inner side of the guide rail 302. An electric control push rod 311 is installed inside the fastening guide seat 304. One end of the electric control push rod 311 is installed with a toothed push plate 314. The toothed push plate 314 can be engaged with or separated from the positioning tooth groove 3020 on the guide rail 302 under the push control of the electric control push rod 311. When in the engaged state, the position of the self - adjusting lifting substrate 306 is fixed. On the contrary, when in the separated state, the self - adjusting lifting substrate 306 can move and, under the action of the adjusting floating body 307 and its own gravity, move to the water surface position, thereby achieving the effect of automatic position adjustment.

[0056] Specifically, as Figure 6 shown in the figure, in order to accurately control the height of the self - adjusting lifting substrate 306 and ensure the energy conservation of the device, in this embodiment, a rotary encoder 312 is installed inside the protruding part 305. The rotary encoder 312 can monitor the swing angle of the swing shaft 315. The wave power generation system further includes a control unit. The control unit includes a data acquisition module, a data analysis module, and a control module. Among them, the data acquisition module is used to collect the swing angle data of the swing shaft 315. The data analysis module generates the vertical height difference between the water surface and the swing shaft 315 based on the swing angle data of the swing shaft 315. The control module controls the telescopic movement of the electric control push rod 311 based on the height difference.

[0057] Specifically, the data acquisition module is collected through the rotary encoder 312. The method by which the data analysis module generates the vertical height difference between the water surface and the swing shaft 315 based on the swing angle data of the swing shaft 315 is as follows:

[0058] Denote the vertical height difference between the water surface and the swing shaft 315 as H, the distance from the swing floating body 301 to the swing shaft 315 as L, the maximum swing angle of the swing shaft 315 per unit time as αmax, and the minimum swing of the swing shaft 315 per unit time as αmin. Then the average swing angle of the rocker plate 300 per unit time is α, and α=(αmax + αmin) / 2;

[0059] Through trigonometric functions, it can be known that the vertical height difference H between the water surface and the swing shaft 315 per unit time is H = L×sinα;

[0060] The method by which the control module controls the telescopic movement of the electric control push rod 311 based on the height difference is as follows:

[0061] Set the threshold value of the vertical height difference between the water surface and the swing shaft 315 per unit time as H1, where H1>0;

[0062] When H ≤ H1, the control module controls the electric push rod 311 to engage the toothed push plate 314 with the positioning tooth grooves 3020 on the guide rail 302, fixing the position of the self - adjusting lifting substrate 306 (indicating that the current angle of the rocker plate 300 is appropriate, the water level has little influence on the rocker plate 300, and it can swing normally to generate mechanical energy).

[0063] When H > H1, the control module controls the electric push rod 311 to separate the toothed push plate 314 from the positioning tooth grooves 3020 on the guide rail 302. The self - adjusting lifting substrate 306 can move. Under the action of the adjusting float 307 and its own gravity, it moves to the water surface position (indicating that at this time, the current upward or downward swing angle of the rocker plate 300 is too large, the water level has a greater influence on the rocker plate 300, and it cannot swing normally to generate mechanical energy, and the overall height of the rocker plate 300 needs to be adjusted), and the self - adjusting lifting substrate 306 can be locked through the toothed push plate 314. This can ensure the energy - saving performance of the device while accurately controlling the height of the self - adjusting lifting substrate 306 and guaranteeing the power generation efficiency of the device.

[0064] Embodiment 2

[0065] Refer to Figure 1 - Figure 5 This embodiment provides a technical solution: a wave and tidal energy power generation device combined with a caisson - type seawall.

Among them, the water inlet 200 is opened above the front side of the box body 1, and the water outlet 201 is opened below the front side of the box body 1. A water storage chamber 100 is provided inside the box body 1. A first impeller 203 is installed at the position of the water inlet 200 above the water storage chamber 100, and a gate 204 is installed at the position of the water outlet 201 inside the water storage chamber 100. A first generator set 202 is installed outside the box body 1 at the position of the first impeller 203. Therefore, when the tide level rises to the position of the water inlet 200, the tide water flows into the water storage chamber 100 from the water inlet 200. During the inflow process, the first impeller 203 is driven to rotate, and the first generator set 202 converts the mechanical energy of the first impeller 203 into electrical energy, achieving the effect of power generation during flood tide.

[0066] It should be noted that: the water inlet 200 is below the high point of the tide water during flood tide, and the water outlet 201 is above the low point of the tide water during ebb tide. The water inlet 200 intakes water during flood tide, and the water outlet 201 discharges water during ebb tide. During flood tide, the water outlet 201 is closed by the gate 204.

[0067] Specifically, as Figure 1 - Figure 5As shown, in order to achieve dual power generation during high tide and low tide, in this embodiment, a return flow channel 207 is provided below the interior of the box body 1. A second impeller 206 is installed in the return flow channel 207. A second power generation set 205 is installed outside the box body 1 at the position of the second impeller 206. The second power generation set 205 is used to convert the mechanical energy of the second impeller 206 into electrical energy to achieve the effect of power generation during low tide. During or after low tide, the gate 204 is opened, and the water in the water storage chamber 100 flows out through the return flow channel 207. During the flowing process, it drives the second impeller 206 to rotate, generating mechanical energy, and thus achieving power generation.

[0068] Specifically, as Figure 3 、 Figure 4 shown, an energy storage chamber 101 is provided above the interior of the box body 1. An electricity storage device 102 is installed in the energy storage chamber 101. Among them, the electricity storage device 102 is electrically connected to the first power generation set 202, the second power generation set 205, and the third power generation set 313.
