Description

Technical Field

[0001] This invention relates to the field of wave energy power generation technology, and in particular to a large floating platform wave energy power generation device that integrates aquaculture cages. Background Technology

[0002] In practical marine energy, wave energy is a common green energy source. Wave power generation devices utilize the pressure difference created by water level changes during wave undulations to generate electricity and supply gas. These devices typically require installation and fixation on floating platforms to ensure stable power generation. These floating platforms are often further equipped with aquaculture cages to increase economic benefits. Current wave power generation devices usually use open-type wave column shells, which are prone to overflow and splashing during periods of significant water level fluctuation, accelerating pipe corrosion. Furthermore, because the wave column shell is constantly submerged in seawater, it is easily attached to marine organisms, affecting its internal volume and reducing the smoothness of its inner wall, increasing turbulence and making it difficult to achieve automatic seawater isolation and self-cleaning maintenance without affecting normal wave power generation. Additionally, the internal volume of traditional wave column shells is usually fixed; under strong swells, this can easily lead to excessive internal pressure, causing overload of the power generation equipment and hindering automatic buffering protection.

[0014] This invention provides a large-scale floating platform wave energy power generation device that integrates aquaculture cages, which has the following beneficial effects: The floating isolator used in this invention can isolate the liquid surface inside the oscillating water column shell, preventing seawater from splashing and intruding into the external pipeline of the air duct when the waves rise and fall. In the event of strong swells and seawater overflowing, the floating box can also effectively isolate the lower seawater. At the same time, when the seawater rises and falls, it can push the floating box to move horizontally, making the liquid surface fluctuation inside the oscillating water column shell more stable. It is more suitable for use in oscillating water column shells with wider cross sections. In addition, it can be used with rubber rings to seal and fit the inner wall of the oscillating water column shell.

[0015] In addition, the venting unit ensures that the floating box can accurately fit the liquid surface inside the oscillating water column shell and rise and fall with the liquid level. This prevents the air cavity between the liquid surface and the bottom of the floating box from gradually increasing due to factors such as water flow impact, eliminating the need for manual inspection. When the floating box is pushed upward by the rising wave liquid level, if there is an air cavity between the bottom of the floating box and the liquid surface, the control switch will open the solenoid valve to vent the air.

[0016] In addition, the use of an overpressure buffer can automatically release pressure and buffer when the floating box moves too fast and for too long due to high surge intensity inside the oscillating water column shell, thus avoiding overpressure inside the oscillating water column shell.

Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the described embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1: Please refer to Figures 1 to 11 : This invention proposes a large floating platform wave energy power generation device integrating aquaculture cages, including a floating installation part 1, on which an oscillating water column part 2 is installed; the oscillating water column part 2 is used to generate electricity through wave energy; a floating isolation component 3 is installed inside the oscillating water column part 2; the floating isolation component 3 is used to clean the oscillating water column part 2; an exhaust part 4 is installed on the oscillating water column part 2; the exhaust part 4 is connected to the floating isolation component 3; an overpressure buffer 5 is installed on the oscillating water column part 2; the floating installation part 1 includes: a mounting float 101 and connecting rings 102, with four connecting rings 102 fixedly installed on both sides of the mounting float 101; the mounting float 101 has a hollow structure; the mounting float 101 is used to float on the sea surface.

[0023] In this embodiment, the floating installation part 1 further includes: a series steel wire rope 103, a fixing plate 104, and a clamping steel ring 105. The series steel wire rope 103 is fixedly sleeved on two connecting rings 102 located on the upper side of the installation float 101. The series steel wire rope 103 is used to connect two adjacent installation floats 101 in series. The two ends of the series steel wire rope 103 are bent and clamped and fixed by steel wire rope clamps. The fixing plate 104 is welded to the inner side of the installation float 101. The clamping steel ring 105 is fixedly installed on the fixing plate 104 by bolts. The clamping steel ring 105 is used to clamp the aquaculture net. The vibrating water column part 2 includes: a vibrating water column shell 201, a bottom plate 202, and an air guide pipe 203. The vibrating water column shell 201 is fixedly installed in front of the installation float 101. The front side of the vibrating water column housing 201 has an opening 2011; a base plate 202 is fixedly installed at the bottom of the vibrating water column housing 201; a through hole is provided on the base plate 202; an air guide pipe 203 is fixedly installed at the top of the vibrating water column housing 201; an anti-corrosion layer is provided on the vibrating water column housing 201; the air guide pipe 203 is connected to the Wells turbine through a hose; the floating isolation component 3 includes: a lifting slide shaft 301, a floating box 302 and a rubber ring 303; two lifting slide shafts 301 are fixedly installed inside the vibrating water column housing 201, and the two lifting slide shafts 301 are respectively fixedly installed on the base plate 202; the floating box 302 is slidably installed on the two lifting slide shafts 301, and the floating box 302 is located inside the vibrating water column housing 201; the floating box 302 is a hollow structure. The floating box 302 has two rubber rings 303 fixedly sleeved on its outer side, and the two rubber rings 303 are slidably sleeved on the oscillating water column shell 201. The floating isolation component 3 also includes a cleaning brush frame 304, with two protrusions on the inner side of the oscillating water column shell 201 to limit the maximum falling height of the cleaning brush frame 304. The cleaning brush frame 304 is fixedly installed at the bottom of the floating box 302. The cleaning brush frame 304 has bristles on its outer side. The bristles on the outer side of the cleaning brush frame 304 are attached to the inner side of the oscillating water column shell 201. The floating isolation component 3 can isolate the liquid surface inside the oscillating water column shell 201. When the seawater rises and falls, splashes, or overflows due to strong swells, the floating box 302 can be used to isolate the seawater below. When the seawater rises and falls, it can push the floating box 302 to move horizontally, making the liquid surface fluctuation inside the oscillating water column shell 201 more stable. This is more suitable for use with oscillating water column shells 201 with wider cross-sections. In addition, it can be used with the rubber ring 303 to seal and fit the inner wall of the oscillating water column shell 201. At the same time, it can be used with the bristles on the cleaning brush frame 304 to clean the inner wall of the oscillating water column shell 201, preventing the inner wall of the oscillating water column shell 201 from being immersed in seawater for a long time and attaching a large number of marine organisms, such as barnacles. This can reduce the manual cleaning cycle. At the same time, the potential energy generated by the wave fluctuation can be used to complete the automatic cleaning. The use of the floating installation part 1 can facilitate the installation of aquaculture nets to form an aquaculture net cage structure, which can increase economic benefits.

[0024] In this embodiment, the venting unit 4 includes: a venting mounting shell 401, a control switch 4011, a connecting hose 4012, and a control float 402. The venting mounting shell 401 is fixedly mounted on the vibrating water column shell 201 by bolts. The control switch 4011 is fixedly mounted on the top of the venting mounting shell 401, and the pressing end of the control switch 4011 protrudes from the top of the inner side of the venting mounting shell 401. The connecting hose 4012 is fixedly mounted on the bottom of the venting mounting shell 401, and the connecting hose 4012 passes through the vibrating water column shell 201. The end of the connecting hose 4012 is fixedly mounted on the float box 302. The connecting hose 4012 passes through the float box 302. The control float 402 is slidably sleeved inside the venting mounting shell 401. Furthermore, the control float 402 has a hollow structure; a through hole is provided in the middle of the control float 402; the control float 402 is located below the control switch 4011; the exhaust section 4 also includes: a buffer sleeve 403, with a gap between the outer side of the buffer sleeve 403 and the control float 402; the buffer sleeve 403 is fixedly installed inside the exhaust mounting shell 401, and the buffer sleeve 403 is located in the through hole in the middle of the control float 402; a through groove is provided on the buffer sleeve 403; the buffer sleeve 403 is connected to the connecting hose 4012; the exhaust section 4 also includes: a guide pipe 404, a one-way valve 405, and a solenoid valve 406, the guide pipe 404 is fixedly installed on the exhaust mounting shell 401; the one-way valve 405 is installed on the guide pipe 404. A solenoid valve 406 is fixedly installed on the guide pipe 404; a control switch 4011 is electrically connected to the solenoid valve 406; a flexible hose is connected to the guide pipe 404; the exhaust section 4 ensures that the floating box 302 can accurately fit the liquid surface inside the oscillating water column shell 201 and rise and fall with the liquid level. Because the floating box 302 rises and falls with the liquid level in real time, due to factors such as different wave heights, the floating box 302 is in a condition where the bottom is higher than the upper edge of the opening 2011 for a long time. This structure can prevent the liquid surface inside the oscillating water column shell 201 from gradually increasing the volume of the air cavity between the liquid surface and the bottom of the floating box 302 due to factors such as water flow impact and bubble accumulation. When the waves push the floating box 302 upward, the liquid surface and the floating box... The air bubble area between the bottom of 302 will be compressed, and there will be a buffer gap in the water pressure transmission, which will directly affect the gas generation efficiency when the wave pushes the floating box 302 upward. This structure can control the automatic venting when the floating box 302 moves upward with the liquid level, without the need for manual operation and inspection. When the floating box 302 is pushed upward by the rising liquid level of the wave, if there is an air vent between the bottom of the floating box 302 and the liquid surface, the control switch 4011 will control the solenoid valve 406 to be in the open state. At this time, as the wave pushes the floating box 302 upward, there is air resistance when the floating box 302 moves upward. At this time, the seawater on the liquid surface will be poured into the connecting hose 4012 and then into the venting housing 401, ensuring that the floating box 302 effectively fits the seawater surface.

[0025] In Example 2, based on Example 1, the overpressure buffer 5 includes: a buffer sleeve 501, an inner piston 502, and a buffer spring 503. The buffer sleeve 501 has a through hole; the buffer sleeve 501 is fixedly installed on the vibrating water column housing 201; the inner side of the buffer sleeve 501 has an annular groove; the inner piston 502 is slidably sleeved on the inner side of the buffer sleeve 501, and two sealing rings are sleeved on the outer side of the inner piston 502; the buffer spring 503 is sleeved inside the buffer sleeve 501, and the buffer... One end of the spring 503 is fixedly connected to the inner side of the buffer sleeve 501, and the other end of the buffer spring 503 is fixedly connected to the inner piston 502; the overpressure buffer 5 also includes: insert pins 504 and collapse springs 505. Four insert pins 504 are slidably inserted into the inner piston 502, and the ends of the four insert pins 504 are hemispherical structures; four collapse springs 505 are sleeved on the inner piston 502, and one end of each of the four collapse springs 505 is fixedly connected to the insert pin 504. The other end of the spring 505 is fixedly connected to the inner side of the inner piston 502; the end of the plug 504 is inserted into the annular groove provided on the inner side of the buffer sleeve 501, and the insertion length of the plug 504 in the annular groove on the inner side of the buffer sleeve 501 is less than the radius of the plug 504; the overpressure buffer 5 can automatically release pressure and buffer when the floating box 302 moves too fast and for too long due to the high surge intensity in the oscillating water column housing 201, which can avoid overpressure inside the oscillating water column housing 201, and avoid damage to the power generation equipment and deformation of the oscillating water column housing 201 caused by excessive air pressure, which can improve the safety of this structure. The overpressure buffering effect is achieved by increasing the internal cavity volume of the oscillating water column housing 201; once the pressure value inside the oscillating water column housing 201 exceeds the standard, because the end of the plug 504 is an arc-shaped hemispherical structure, the plug 504 will be squeezed and collapsed by the annular groove on the inner side of the buffer sleeve 501 under the action of air pressure.

[0026] The working principle of this embodiment is as follows: Anchorage points such as caissons are pre-sunk into the seabed, and anchorage is achieved by connecting the lower connecting ring 102 on the installation buoy 101 with anchoring wire ropes. The number of installation buoys 101 can be set according to requirements. When installing buoys 101 in series, the upper connecting ring 102 on adjacent installation buoys 101 passes through the series wire rope 103 and is clamped and fixed using wire rope clamps. The top edge of the aquaculture net can be placed between the fixing plate 104 and the clamping steel ring 105, and the aquaculture net can be clamped and positioned by tightening the clamping steel ring 105 with bolts. After the oscillating water column housing 201 is put into operation, when the wave reaches the opening 2011 of the oscillating water column housing 201, the rising liquid level will push the floating box 302 and the rubber ring 303 upward together. At this time, the air inside the oscillating water column housing 201 is compressed and discharged through the air guide pipe 203 to supply air to the Wells turbine. As the liquid level inside the oscillating water column housing 201 drops, under the action of negative pressure, the floating box 302 will also move downward with the liquid level. The oscillating water column housing 201 will draw air through the air guide pipe 203. During the up and down movement of the floating box 302, the rubber ring 303 slides and adheres to the oscillating water column housing 201 in real time to maintain the seal. At the same time, the bristles on the rubber ring 303 and the cleaning brush holder 304 will also clean the oscillating water column housing 201. The inner wall of the oscillating water column shell 201 reduces the amount of marine organisms attached to the inner wall of the oscillating water column shell 201. When the liquid level in the oscillating water column shell 201 fluctuates normally, the pressure value in the oscillating water column shell 201 is in a normal state. At this time, the end of the plug 504 is inserted into the annular groove provided on the inner side of the buffer sleeve 501. Once the pressure value in the oscillating water column shell 201 exceeds the standard, because the end of the plug 504 is an arc-shaped hemispherical structure, under the action of air pressure, the upward pressure of the inner piston 502 exceeds the standard. The plug 504 will be squeezed and collapsed by the annular groove on the inner side of the buffer sleeve 501, compressing the collapse spring 505. At this time, the inner piston 502 will move directly upward to compress the buffer spring 503 for air pressure buffering. When the floating tank 302 is pushed upward by the rising liquid level and waves, if there is an air vent between the bottom of the floating tank 302 and the liquid surface, and since the connecting hose 4012 is located above the floating tank 302, the vent housing 401 is also empty of seawater. At this time, the control float 402 will not press the control switch 4011. Instead, the control switch 4011 will open the solenoid valve 406. As the waves push the floating tank 302 upward, air resistance causes seawater to enter the connecting hose 4012 and then the vent housing 401. During this process, the buffer sleeve 403 prevents the seawater from pushing the control float 402 upward and causing accidental activation. As the amount of seawater increases, the check valve 405 is activated, and the vent housing 401... After the seawater level in 01 rises, the buoyancy of the control float 402 will cause it to float upwards. Pressing the control switch 4011 will quickly close the solenoid valve 406, achieving a seal and preventing a large amount of seawater leakage. At this time, the floating box 302 and the seawater surface are in a tight fit. Subsequently, when the floating box 302 moves downwards, regardless of whether the solenoid valve 406 is open or closed, the one-way valve 405 is always in a one-way closed state. If the water level in the vent housing 401 drops due to factors such as wave impact, the control float 402 will move downwards synchronously, and the control switch 4011 will no longer be pressed. This facilitates the filling of seawater into the vent housing 401 when the water level rises due to waves, ensuring that the bottom of the floating box 302 and the seawater surface are always in a cavity-free state.
