Description

TECHNICAL FIELD

[0002] Wave energy power generation refers to using the kinetic energy of waves to drive corresponding power generation equipment to generate electricity. Since no pollution is generated during power generation, wave energy power generation is an ideal clean energy source. Since China has a vast sea area, wave energy power generation has broad development prospects in China.

[0003] Traditional wave energy power generation mainly adopts two forms: the first form is to use waves to drive a float to move up and down, thereby using the potential energy difference in the up-and-down movement of the float to generate electricity. However, the efficiency of this power generation form is affected by the height of the spray, and it is difficult to effectively utilize the waves with high speed but low height, so the energy conversion efficiency is not ideal. The second form is to use wave energy to push a float or a plate to swing, thereby generating electricity in the process of swinging the float or the plate. However, since the float and the plate have directionality in the swinging process, it is also difficult to effectively utilize wave energy of different directions. Moreover, the above two wave energy power generation devices need to select appropriate wind and wave conditions, and the use conditions are harsh, which makes it difficult for the existing wave energy power generation devices to meet the current power generation demand.

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical scheme of the present application clear, complete description, and the advantages are more clear and obvious, the following will be further described in detail by combining with the drawings. It should be understood that the specific embodiments described here are part of the embodiments of the present application, not all embodiments, only to explain the embodiments of the present application, and not for the purpose of limiting the embodiments of the present application, all other embodiments obtained by the person skilled in the art without doing creative work, belong to the scope of protection of the present application.

[0033] Embodiment one: please refer to Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 8 and Figure 9The application provides a wave power generation device for sea surface, which comprises a supporting device 3, a squeezing device 6, a variable volume container 5 and a second generator 16.

[0034] Please refer to Figure 1 、 Figure 2 、 Figure 5 and Figure 6 The squeezing device 6 comprises a supporting connecting frame 604 fixedly installed on the mounting column 1, and a squeezing plate 603 hingedly installed on the supporting connecting frame 604, and the end of the squeezing plate 603 is connected with the supporting connecting frame 604 through a reset spring 602, according to the need of power generation, the squeezing device 6 can be provided with multiple along the outside of the mounting column 1, preferably four or eight in a circumferential array, in working time, the squeezing plate 603 will be kept in the initial position under the support of the reset spring 602, and when the sea wave impacts the squeezing plate 603, the squeezing plate 603 will swing under the impact of the sea wave, and after the impact of the sea wave is over, the squeezing plate 603 continues to return to the initial position under the support of the reset spring 602 and is kept in the initial position.

[0035] Please refer to Figure 1 、 Figure 2 、 Figure 5 、 Figure 6 、 Figure 8 and Figure 9 The variable volume container 5 comprises a flexible bag 505 fixedly installed between the supporting connecting frame 604 and the squeezing plate 603 and changing the internal volume of the variable volume container 5 through the swing of the squeezing plate 603, and a circulating solution is arranged in the flexible bag 505, at least two side supporting plates 503 are installed on the inner wall of the flexible bag 505, the side supporting plates 503 are connected and kept in relative position through elastic strips 504, the elastic strips 504 are rubber rods, at least two intermediate connecting bases 502 are installed in the flexible bag 505, the intermediate connecting bases 502 are connected through supporting springs 501, and the intermediate connecting bases 502 and the side supporting plates 503 are connected through the supporting springs 501. When the flexible bag 505 is externally squeezed, the force receiving part of the flexible bag 505 will transmit the force to other areas through the circulating solution, the side supporting plates 503, the elastic strips 504, the intermediate connecting bases 502 and the supporting springs 501, so that the flexible bag 505 is deformed. When the external force disappears, the flexible bag 505 will gradually return to the initial shape under the elastic force of the elastic strips 504 and the supporting springs 501 and the push of the reset spring 602.

[0036] Please refer to Figure 1 、 Figure 2、 Figure 5 and Figure 6 The top of the support connecting frame 604 is fixedly installed with a second generator 16, a micro water turbine 7 and a liquid storage tank 9. The power output end of the micro water turbine 7 is used to drive the second generator 16 to generate electricity. The water outlet end of the micro water turbine 7 is connected to the top of the liquid storage tank 9 through a return pipe 8. The water inlet end of the micro water turbine 7 is communicated with the inside of the flexible bag 505 through a liquid discharge pipe 12. The liquid discharge pipe 12 is installed with a liquid discharge one-way valve 11 which allows only the circulating solution to flow from the inside of the flexible bag 505 to the micro water turbine 7. The bottom of the liquid storage tank 9 is communicated with the inside of the flexible bag 505 through a liquid inlet pipe 14. The liquid inlet pipe 14 is fixedly installed with a liquid inlet one-way valve 13 which allows only the circulating solution to flow from the liquid storage tank 9 to the inside of the flexible bag 505.

[0037] When the variable volume container 5 is squeezed, the inside of the flexible bag 505 will be compressed. Since the deformation amount of the flexible bag 505 itself is limited, it is difficult to eliminate the squeezing force by the expansion of the flexible bag 505 itself. Therefore, the circulating solution in the flexible bag 505 will be squeezed into the liquid inlet pipe 14, and then flow into the micro water turbine 7 through the liquid inlet pipe 14 to drive the micro water turbine 7 to rotate, so as to drive the second generator 16 to generate electricity by the micro water turbine 7. The circulating solution discharged from the micro water turbine 7 will be collected by the liquid storage tank 9. When the squeezing pressure of the flexible bag 505 disappears, the flexible bag 505 will be restored to the initial shape under the driving of the elastic strips 504, the supporting springs 501 and the return springs 602. At this time, the inside of the flexible bag 505 has a larger volume, and the circulating solution in the liquid storage tank 9 will be sucked into the inside of the flexible bag 505 through the liquid inlet pipe 14. Therefore, the circulating solution can be repeatedly circulated between the flexible bag 505 and the liquid storage tank 9, and the second generator 16 can be driven to generate electricity by the micro water turbine 7 during the circulation process. Thus, the wave energy is utilized to generate electricity.

[0038] In this embodiment, there are two ways to cause the deformation of the flexible bag 505. The first way is that the wave directly impacts on the squeezing device 6, so that the squeezing device 6 swings. At this time, the squeezing plate 603 will apply pressure to the flexible bag 505, so that the circulating solution in the flexible bag 505 enters the micro water turbine 7 to drive the second generator 16 to generate electricity. In this way, the shape, area and height of the squeezing plate 603 can be customized according to the local wave conditions, so that the wave impact can be received at a position above the water surface. Thus, the flexible bag 505 does not need to be made very large to receive sufficient wave impact, so that the kinetic energy carried by large waves which cannot directly impact the flexible bag 505 can be better utilized.

[0039] The second way is that the flexible bag 505 directly receives the impact from the waves. Since most of the flexible bag 505 is immersed in water, the change of the water surface waves will be able to impact each part of the flexible bag 505, and make the flexible bag 505 deform to change the internal volume of the flexible bag 505 to generate electricity. The advantage of this way is that it can effectively directly utilize the flexible bag 505 to receive the extrusion of waves from all directions, so as to utilize the kinetic energy carried by the waves in all directions. The disadvantage is that it is limited by the size of the flexible bag 505, and cannot utilize the kinetic energy of the waves that do not directly impact the flexible bag 505. Therefore, the combination of the above two ways can make the flexible bag 505 more effectively utilize various waves to generate electricity, and at the same time, the deformation of the flexible bag 505 is used to convert the kinetic energy inside the waves. Compared with the traditional utilization of the up and down floating of the float to utilize the wave energy to generate electricity, it can better convert the kinetic energy carried by the waves, thereby improving the efficiency of the wave energy generation. Therefore, it has good adaptability to different wind and wave conditions, so as to better be used in sea areas with different wind and wave conditions, and has better application prospect.

[0040] The wave energy generation device provided by the embodiment can effectively drive the variable volume container 5 to deform by the waves, thereby driving the circulating solution to circulate between the variable volume container 5 and the liquid storage tank 9, and further driving the micro water turbine 7 to rotate, so as to utilize the micro water turbine 7 to drive the second generator 16 to generate electricity. Moreover, the different waves can be utilized through the two forms of the direct impact of the waves on the flexible bag 505 and the impact and extrusion of the wave on the plate 603, thereby improving the adaptability of the device to different wind and wave conditions, and having higher power generation efficiency. The problems of low power generation efficiency and poor adaptability of the existing wave energy generation device are solved, and the utilization efficiency of the wave energy can be effectively improved.

[0041] Embodiment two: please refer to Figure 1 , Figure 2 and Figure 3On the basis of embodiment one, the top of the mounting column 1 is provided with a sign device 2 for warning nearby ships not to approach, and the sign device 2 comprises a sleeve 205 fixedly installed on the top of the mounting column 1 by bolts, a telescopic rod 203 slidably installed on the sleeve 205, and the sleeve 205 and the telescopic rod 203 are fixed by a fixed screw knob 204, a top bracket 202 fixedly installed on the top of the telescopic rod 203, and a warning air bag 201 serving as a sign installed on the top bracket 202. The installation height of the telescopic rod 203 can be adjusted by the fixed screw knob 204, so that the warning air bag 201 is at an appropriate height for warning, so that the nearby ships can be prevented from approaching the device, thereby avoiding the damage caused by the impact of the ships to affect the power generation efficiency. Thus, the wave power generation device can be applied in a wider sea area, without being set in a specific area to avoid ships, so that the wave power generation can be more effectively developed under the premise of ensuring the safety of ship navigation. Further solve the problem of low power generation efficiency and poor adaptability of the existing wave power generation device, can effectively improve the utilization efficiency of wave energy.

[0042] Embodiment three: please refer to Figure 1 、 Figure 2 、 Figure 5 、 Figure 6 and Figure 7 On the basis of embodiment two, the support connecting frame 604 is provided with a power generation device 4, and the power generation device 4 comprises a first generator 406, a speed increaser 405 and a winding cooperation seat 402 fixedly installed on the support connecting frame 604 by bolts, a butt joint rotating shaft 401 rotatably installed on the winding cooperation seat 402, and a pulling rope 601 fixedly installed at the end of the extrusion plate 603. The butt joint rotating shaft 401 is coaxially fixed with the power input end of the speed increaser 405, the power output end of the speed increaser 405 is coaxially fixed with the main shaft of the first generator 406, the butt joint rotating shaft 401 is fixedly installed with a winding drum 404, and the winding drum 404 is used for fixing and winding the pulling rope 601. The butt joint rotating shaft 401 and the winding cooperation seat 402 are installed with a clockwork 403 for resetting the winding drum 404 to tension the pulling rope 601 again. The support connecting frame 604 is fixedly installed with a guide pulley 15 for changing the movement direction of the pulling rope 601, and the extrusion plate 603 and the support connecting frame 604 are both glued with a flexible bag 505.

[0043] Wherein, since the variable volume container 5 has limited deformation amount in unit time, it has certain output power limit, which makes it necessary to store energy temporarily through the extrusion plate 603 and the reset spring 602. Specifically, the extrusion plate 603 is made of a certain elastic plate material, such as a plastic plate or a composite fiber plate. When the wave hits the extrusion plate 603 and causes the variable volume container 5 to reach the limit of being extruded, the wave will continue to push the extrusion plate 603 to deform, thereby storing energy in the reset spring 602 and the extrusion plate 603. In the process of deformation of the extrusion plate 603, the clockwork 403 continues to tension the pull rope 601. When the extrusion plate 603 is no longer impacted by the wave, the extrusion plate 603 will restore to the original position under the elastic force of itself and the push of the reset spring 602. In the process of restoration, the extrusion plate 603 and the reset spring 602 release the energy stored in themselves to drive the pull rope 601 to move, thereby driving the first generator 406 to generate electricity, thereby more efficiently utilizing the energy in the wave and improving the adaptability of the device to large waves. The base 306 is fixedly installed with an energy storage device 10 electrically connected with the first generator 406 and the second generator 16. The energy storage device 10 is connected to the power grid through the submarine cable. The energy storage device 10 can use lithium battery or storage battery. The energy storage device 10 can store the power generated by the first generator 406 and the second generator 16 through the addition of a rectifier. The energy storage device 10 can also convert the electrical energy in the energy storage device 10 into alternating current during the power peak period through the addition of an inverter, and supply it to the power grid through the submarine cable, thereby realizing the storage and peak regulation of electrical energy, and improving the energy utilization efficiency. Further solve the problem of low power generation efficiency and poor adaptability of the existing wave power generation equipment, can effectively improve the utilization efficiency of wave energy.

[0044] Embodiment four: please refer to Figure 1 , Figure 2 and Figure 4On the basis of embodiment three, the base 306 is fixedly installed with a sliding guide pipe 305, and the sliding guide pipe 305 is slidably installed with a sliding column 301. The sliding guide pipe 305 is provided with a sliding matching groove 303 for draining water, and the bottom of the sliding column 301 is fixedly installed with a sliding matching protrusion 304 which slides along the guide of the sliding matching groove 303. The mounting column 1 is fixedly installed with the top of the sliding column 301. The outside of the sliding column 301 is provided with a bottom float 302 for adjusting the buoyancy. The top of the bottom float 302 is fixedly installed with the top of the sliding column 301, and the bottom of the bottom float 302 is fixedly installed with the sliding matching protrusion 304. The bottom float 302 is circumferentially arranged with at least two along the outside of the sliding column 301, and the top of the sliding matching groove 303 is closed to limit the moving position of the sliding matching protrusion 304 and prevent the sliding column 301 from being separated from the sliding guide pipe 305. The sliding matching groove 303 can drain the water flow in the sliding guide pipe 305, thereby avoiding the water flow accumulated at the bottom of the sliding guide pipe 305 from hindering the normal movement of the sliding column 301. On the other hand, the sliding matching groove 303 can also guide the sliding matching protrusion 304 to move up and down, so that the sliding column 301 can slide up and down accurately.

[0045] The bottom float 302 is used to adjust the overall buoyancy of the wave power generation device, so as to ensure that the variable volume container 5 can float on the water surface at a proper height. The sliding guide pipe 305 and the sliding column 301 are installed in the form of sliding sleeve connection, which can make the components installed on the mounting column 1 always float on the water surface. Specifically, because there is tide on the sea surface, and the height difference of the sea surface caused by the tide can exceed two meters or more, which leads to that if the sliding guide pipe 305 is not connected with the sliding column 301 in the form of sliding, when the tide rises, the squeezing device 6 and the variable volume container 5 will be submerged in more area, and at the same time, the base 306 will bear more upward buoyancy, and when the tide falls, the squeezing device 6 and the variable volume container 5 will have more area exposed to the water surface, and at the same time, the base 306 will bear more downward pressure, which will cause the instability of the device work. When the sliding column 301 can slide up and down along the sliding guide pipe 305, the components on the mounting column 1 can maintain the relative height with the water surface, and the sliding column 301 will automatically adjust the height according to the rise and fall of the water surface. At this time, the base 306 and the sliding guide pipe 305 mainly limit the horizontal movement of the sliding column 301, so that the squeezing device 6 and the variable volume container 5 can work stably.

[0046] In addition, the bottom floating tube 302 is arranged in the underwater area, so that the support device 3 can be shaken due to the impact of the sea waves on the extrusion plate 603 and the flexible bag 505. On one hand, the bottom floating tube 302 can provide buoyancy for the entire wave power generation device, and on the other hand, the huge volume of the bottom floating tube 302 itself can also withstand the resistance of the water flow when moving, so as to weaken the amplitude of the support device 3 when shaking underwater to a certain extent, thereby ensuring the stability of the support. In addition, the upper end of the bottom floating tube 302 is fixed with the top of the sliding column 301, and the lower end is fixed with the sliding fitting protrusion 304, so that the sliding column 301 can be more stable under force, thereby avoiding the bending of the sliding column 301, and further ensuring the working stability of the entire device. Further solve the problems of low power generation efficiency and poor adaptability of the existing wave power generation device, and can effectively improve the utilization efficiency of wave energy.

[0047] Embodiment five: on the basis of embodiment four, the application further provides a use method of the wave power generation device on the sea surface, comprising the following steps:

[0048] Step one: first, the corresponding parts are transported to the designated sea area by the work ship, then the base 306 is fixed on the seabed, then the sliding column 301 and the mounting column 1 are fixed in sequence, and then the bottom floating tube 302 is fixed on the sliding column 301. During installation, the buoyancy provided by the bottom floating tube 302 is adjusted in real time, so that the mounting column 1 can float out of the water, and then other parts located on the mounting column 1 can be fixed on the mounting column 1. During installation, the extrusion plate 603 with appropriate shape, size and installation height needs to be selected according to the local wind and wave conditions, and after installation, the buoyancy adjusted by each bottom floating tube 302 is adjusted again, so that the variable volume container 5 can float out of the water to a specified height, while avoiding the inclination of the mounting column 1 due to the unbalanced buoyancy.

[0049] Step two: then, the first generator 406 and the second generator 16 are connected to the energy storage device 10 through the cable located in the sliding column 301 and the mounting column 1, and then the energy storage device 10 is connected to the power grid through the submarine cable. Then, it is detected whether the first generator 406 and the second generator 16 can work normally, and the tension of the pulling rope 601 and the natural length of the reset spring 602 are adjusted again according to the working condition, so that the first generator 406 and the second generator 16 can obtain the best power generation efficiency.

[0050] While the forgoing detailed description of the application has shown specific embodiments of the application, it is to be understood that changes and modifications can be made to the specific embodiments without departing from the spirit and scope of the application as defined by the claims set forth below.
