[0002] Wave power generation devices are the main equipment for generating electricity using wave energy. Among them, the floating wave power generation is to directly contact the floating body with the sea water. The floating body moves up and down with the waves, converting the wave energy into the mechanical energy held by the floating body, and then further converting the mechanical energy of the floating body to finally obtain electrical energy.

DETAILED DESCRIPTION

[0033] In order to clearly illustrate the technical features of the present solution, the present invention is described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0034] It should be noted that many specific details are described in the following description to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0035] like Figure 1-Figure 3 As shown in the figure, the floating wave energy integrated power supply platform of this embodiment includes a frame 100 for installing a wave energy capture mechanism. Generally, the frame 100 includes an upper deck 101, a lower deck 102 and a column 103, and both ends of the column 103 are respectively connected to the upper deck 101 and the lower deck 102 to form a part or all of the frame structure, and an upper cabin 104 and a bottom cabin 105 are respectively arranged on the upper deck 101 and the lower deck 102.

[0036] A passage is defined in the column 103, and the passage connects the upper cabin 104 and the bottom cabin 105. A ladder is usually provided inside the passage of the column 103, and the operator can enter the upper cabin 104 from the upper deck 101, and then enter the bottom cabin 105 through the ladder. A pipeline passage is also provided in the column, and the pipeline passage contains hydraulic pipelines, strong power lines, weak point control lines, communication lines, etc. Each type of pipeline is placed separately, and corresponding protection measures are provided.

[0037] The anchor chain system 200 is used to restrict the frame 100 to the sea area. One end of the anchor chain is connected to the lower deck 102, and the other end is fixed to the seabed. Symmetrically and evenly distributed anchor chain joints are arranged on the side of the lower deck 102. One end of the anchor chain is connected to the lower deck 102 through the anchor chain joint, and the other ends of multiple anchor chains are connected together through the anchor chain joint. They are merged into one anchor chain through the anchor chain joint to realize the effective anchoring of the entire platform in the ocean.

[0038] Specifically, the wave energy capture mechanism includes a heave energy capture unit 300 and a pitch energy capture unit 400, so as to improve the wave energy capture efficiency in all directions as much as possible.

[0039] Among them, the heave energy capture unit 300 and the pitch energy capture unit 400 are arranged circumferentially around the column 103, so as to receive wave energy from all directions, and the vertical distance between the pitch energy capture unit 400 and the column is greater than the vertical distance between the heave energy capture unit 300 and the column 103, that is, the pitch energy capture unit 400 is installed on the periphery of the heave energy capture unit 300 to avoid mutual interference, maximize the use of the installation space of the entire platform, and improve the volume utilization rate of the platform.

[0040] In one embodiment, the number of the heave energy capture units 300 and the pitch energy capture units 400 is the same, and the heave energy capture units 300 and the pitch energy capture units 400 are alternately arranged around the column 103 along the circumferential direction.

[0041] In one embodiment, the line connecting any two adjacent heave energy capture units 300 and the pitch energy capture unit 400 therebetween forms a triangle. Further, the triangle is preferably an acute triangle, and more preferably an isosceles triangle, with one pitch energy capture unit 400 located at the vertex of the isosceles triangle, and two heave energy capture units 300 located at the two bottom corners. No matter which direction the waves come from, they can interact with the heave energy capture unit 300 and the pitch energy capture unit 400, avoiding the problem of blocking dispersion or only absorbing wave energy in a single degree of freedom.

[0042] The number of the heave energy capture units 300 and the pitch energy capture units 400 is at least two, and they can be symmetrically distributed around the column 103. In a specific embodiment, the number of the heave energy capture units 300 and the pitch energy capture units 400 is 4, forming a 4+4 combination form, so that waves in each direction can act on the heave energy capture units 300 and the pitch energy capture units 400, there is no shielding between the energy capture units, the energy capture rate is high, and the effect is optimal.

[0043] Specifically, each heave energy capture unit 300 is composed of a heave float 301, a heave energy capture hydraulic cylinder 302 and a heave float guide column 303. The two ends of the heave float guide column 303 are respectively connected to the upper deck 101 and the lower deck 102, and the heave float guide column 303 also constitutes a part of the frame 100. Among them, the heave float 301 is preferably in a frustum shape. The cylinder body and piston rod of the heave energy capture hydraulic cylinder 302 are respectively connected to the heave float 301 and the frame 100, so that the cylinder body of the heave energy capture hydraulic cylinder 302 and the heave float 301 follow the heave float. The heave float guide column 303 guides the heave motion of the heave float 301. When the wave energy drives the heave float 301 to heave, it drives the cylinder body of the heave energy capture hydraulic cylinder 302 to move back and forth. The mechanical energy of the reciprocating motion of the heave energy capture hydraulic cylinder 302 is converted into the pressure energy of the hydraulic oil, thereby realizing the capture and conversion and transmission of wave energy. Different from the traditional device in which the guide column is arranged in the middle and the hydraulic cylinder is arranged around the guide column, in the floating wave energy integrated power supply platform of the present application, the axis of the heaving swing energy capture hydraulic cylinder 302 coincides with the axis of the heaving swing float 301. Specifically, two heaving swing float guide columns 303 pass through the heaving swing float 301 in parallel and symmetrically, and the heaving swing energy capture hydraulic cylinder 302 is located between the two heaving swing float guide columns 303, reducing the difficulty of processing and installation.

[0044] Specifically, each pitch energy capture unit 400 is composed of a pitch float 401, a swing arm 402 and a pitch energy capture hydraulic cylinder 403. One end of the swing arm 402 is pivotally connected to the frame 100, and the other end is connected to the pitch float 401. The cylinder body and piston rod of the pitch energy capture hydraulic cylinder 403 are respectively hinged to the pitch float 401 and the frame 100. The shape of the pitch float 401 is preferably hemispherical. Specifically, the swing arm 402 has a triangular structure, the pitch float 401 is installed on a vertex of the triangle, an I-beam is arranged between two adjacent heaving float guide columns 303, and the side of the swing arm 402 opposite to the pitch float 401 is hinged on the I-beam. The pivot axis of the swing arm 402 is perpendicular to the axis of the column 103, and the axis of the pitch energy capture hydraulic cylinder 403 is arranged approximately along the central axis of the swing arm 401. The swing arm 401 can limit the left and right shaking of the pitch float 401, so that the pitch float 401 can only pitch with the waves, driving the swing arm 402 to swing. When the swing arm 402 swings, it drives the pitch energy capture hydraulic cylinder 403 to move back and forth, and converts the mechanical energy of the reciprocating motion of the pitch energy capture hydraulic cylinder 403 into the pressure energy of the hydraulic oil, thereby realizing the capture and conversion and transmission of wave energy.

[0045] It can be understood that the functions of the heave buoy 301 and the pitch buoy 401 are, on the one hand, to absorb wave energy and convert it into their own mechanical energy, and on the other hand, to provide the buoyancy required by the platform.

[0046] A hydraulic constraint adjustment swing plate 501 is evenly arranged around the lower circumference of the frame 100, one end of the hydraulic constraint adjustment swing plate 501 is hinged to the frame 100, a swing plate hydraulic cylinder 502 is arranged between the hydraulic constraint adjustment swing plate 501 and the frame 100, and a cylinder body and a piston rod of the swing plate hydraulic cylinder 502 are hinged to the frame 100 and the hydraulic constraint adjustment swing plate 501 respectively.

[0047] When working, the floating wave energy integrated power supply platform of the present application has a power generation and energy storage module, an emergency energy storage module, a hydraulic system overload protection module, a power generation module, a power processing module, a storage module, a power output module, a power overload protection module, a central control and work monitoring module, a buoy diving and lifting power module, a hydraulic constraint adjustment swing plate power and stability module, and a bottom cabin hydraulic system control valve group placed in the bottom cabin 105.

[0048] The power generation energy storage module is composed of an accumulator and a corresponding control valve group, which is connected to the high-pressure chambers of the vertical swing energy capture hydraulic cylinder 302 and the pitch energy capture hydraulic cylinder 403. The high-pressure hydraulic oil flowing out of the vertical swing energy capture hydraulic cylinder 302 and the pitch energy capture hydraulic cylinder 403 flows to the power generation module after energy storage, voltage stabilization and buffering in the power generation energy storage module. The power generation energy storage module is used to buffer system fluctuations, absorb hydraulic shocks, and store excess energy, so that the pressure flowing to the power generation module can be stable.

[0049] The high-pressure chambers of the heave energy capture hydraulic cylinder 302 and the pitch energy capture hydraulic cylinder 403 are connected to the hydraulic system overload protection module, which is used to automatically unload the system when the input energy exceeds the system's safety setting value to protect the hydraulic system components and pipelines from damage, and can force the hydraulic system to unload under human intervention or control of the control system.

[0050] The high-pressure hydraulic oil flowing out of the high-pressure chambers of the heave energy capture hydraulic cylinder 302 and the pitch energy capture hydraulic cylinder 403 flows into the power generation module after being stabilized by the power generation and energy storage module. A plurality of generator sets with different power generation powers are arranged in the power generation module. One generator set consists of a hydraulic motor, a generator with corresponding matching power and a control valve group connected to the main power generation oil circuit.

[0051] The power processing module is connected to the generator in the power generation module, and the unstable input power is rectified, filtered, and stabilized, and then stored in the power storage module to meet the power consumption of the platform itself; the unstable input power is rectified, filtered, stabilized, inverted, and boosted, and then output to the power transmission and distribution module through the power output module to meet the power supply of marine instruments and equipment. A power overload protection module is set to achieve overload protection for the power processing module, the power output module, and the power storage module. The power overload protection module consumes the overloaded power and the low-quality power that cannot be output normally.

[0052] The central control and work monitoring module is composed of a central processing unit, a controller, a data information collector, a display, etc. The central control and work monitoring module can receive information sent by the signal processing module or send signals to the signal processing module, collect and store the pressure, flow, and temperature information of the hydraulic system in real time, the power generation module 10 and the power processing module, the power, voltage, current, and temperature information of the storage module, the power, voltage, current, and temperature information of the power output module, and the working state of the floating body diving and lifting power module, the hydraulic constraint adjustment swing plate power and stability module, etc.; and control the signal processing module, the power generation and storage module, the emergency energy storage module, the hydraulic system overload protection module, the power generation module, the power processing module, the storage module, the power output module, the power overload protection module, the floating body diving and lifting power module, the hydraulic constraint adjustment swing plate power and stability module, the bottom cabin hydraulic system control valve group, and the upper cabin hydraulic system control valve group to execute corresponding control instructions and complete related functional actions; and send and store the platform's working state information, monitoring information, and other information to the system work information storage and display module.

[0053] When generating electricity, the central control and work monitoring module collects and analyzes the flow and pressure signals in the power generation hydraulic pipeline in real time. After processing and analyzing the feedback information of the system, the central control and work monitoring module sends the corresponding control instructions to the control valve group of the power generation module, so as to realize the connection or disconnection of the units with different power generation and the main power generation oil circuit of the system. Under different wave conditions, the wave energy captured by the heave buoy 301 and the pitch buoy 401 is different. The central control and work monitoring module selects the generator set with the corresponding power of the power generation module to connect to the main power generation oil circuit to achieve the best power generation and power generation efficiency.

[0054] In extreme weather, the heave buoy 301 can be submerged below the sea surface by controlling the extension and contraction of the heave energy capture hydraulic cylinder 302, and the pitch buoy 401 can be lifted above the sea surface by controlling the extension and contraction of the pitch energy capture hydraulic cylinder 403, thereby avoiding damage to the power generation platform. The buoy diving and lifting power module is composed of an electric motor and a hydraulic motor, and the emergency energy storage module is composed of an accumulator and related control valve groups. The control valve in the bottom cabin hydraulic system control valve group is connected to the upper cabin hydraulic system control valve group, the hydraulic oil tank, and the buoy diving and lifting power module or the emergency energy storage module. When the central control and work monitoring module sends an action instruction that requires the vertical swing float 301 to dive and the pitch float 401 to be lifted, if the power storage module has sufficient power, the floating body diving and lifting power module is operated by an electric motor, and the bottom cabin hydraulic system control valve group controls the motor of the floating body diving and lifting power module to be connected to the working oil circuit, providing energy for the vertical swing float 301 to dive and the pitch float 401 to be lifted; if the power storage module has insufficient power, the control valve group in the emergency energy storage module controls the emergency accumulator group to be connected to the action oil circuit, providing energy for the vertical swing float 301 to dive and the pitch float 401 to be lifted.

[0055] The control valve group in the bottom tank hydraulic system control valve group is connected to the hydraulic constraint adjustment swing plate power and stability module and the swing plate hydraulic cylinder 502. The central control and work monitoring module sends corresponding control instructions to the bottom tank hydraulic system control valve group, the hydraulic constraint adjustment swing plate power and stability module, and executes the telescopic action of the piston rod of the swing plate hydraulic cylinder 502, thereby adjusting the opening angle of the hydraulic constraint adjustment swing plate 501, thereby changing the natural frequency of the platform by changing its own damping under different sea conditions, so that the natural frequency of the platform is close to the wave frequency, increasing the relative motion amplitude between the heave buoy 301, the pitch buoy 401 and the platform, and improving the frequency width of the floating energy capture wave and the efficiency of the capture of the amount. When the waves are small, the piston rod of the swing plate hydraulic cylinder 502 extends, so that the hydraulic constraint adjustment swing plate 501 opens to a horizontal position. When the hydraulic constraint adjustment swing plate 501 is in a horizontal position, its damping reaches a maximum, so the movement amplitude of the platform in the sea water is reduced, thereby increasing the relative movement amplitude between the platform and the heave buoy 301 and the pitch buoy 401, and improving the power generation efficiency; when the waves are large, the piston rod of the swing plate hydraulic cylinder 502 retracts, so that the hydraulic constraint adjustment swing plate 501 rotates to a vertical direction, and its damping reaches a minimum, then the movement amplitude of the platform in the sea water is increased, thereby reducing the relative movement amplitude between the platform and the heave buoy 301 and the pitch buoy 401, and reducing the impact.

[0056] The interior of the bottom cabin 105 is divided into multiple internal cabins, and the cabins are partitioned. The bottom cabin 105 has the function of accommodating and placing related modules. Changes in the equipment carried inside the bottom cabin 105 will cause changes in the buoyancy and center of gravity position of the platform. The buoyancy and center of gravity adjustment cabin 701 is used to adjust the buoyancy and center of gravity position of the platform to ensure the stability of the platform.

[0057] The upper cabin 104 is of closed design, with an antenna on its outer edge, a ventilation duct of a long-term air dryer communicating with the outside world, and an openable and closable door for the entry and exit of personnel and equipment. A signal processing module, a system working information storage and display module, a control system interface module, a power transmission and distribution module, a hydraulic oil tank 601, and an upper cabin hydraulic system control valve group are placed in the upper cabin. The antenna is used to receive the control command signal sent by the land control center and the sending platform working monitoring signal; the signal processing module is used to process the control command signal received by the antenna 1, and transmit the processed signal to the central control and working monitoring module; it is used to process the working control signal output by the central control and working monitoring module, and transmit the signal to the antenna; the system working information storage and display module is used to store system working information and display system working monitoring information, etc.; the control system interface module copies, deletes, and collects system working information through an external computer, and can add new control programs to the central control and working monitoring module, etc.; the power transmission and distribution module realizes the power connection with the marine instruments and equipment, distributes the power to the corresponding offshore power equipment, and sets power protection measures, etc.;

[0058] The two chambers of the vertical swing energy capture hydraulic cylinder 302 and the pitch energy capture hydraulic cylinder 403 are respectively connected to the hydraulic oil tank, the energy storage power generation storage module and the hydraulic system overload protection module through the upper cabin hydraulic system control valve group, so that when the vertical swing energy capture hydraulic cylinder 302 and the pitch energy capture hydraulic cylinder 403 are generating electricity, the low-pressure chamber absorbs oil from the hydraulic oil tank and the high-pressure oil in the high-pressure chamber flows to the power generation energy storage module. The hydraulic oil tank is in a high position, which is conducive to the vacuum oil absorption of the low-pressure chamber; and the high-pressure chamber of the vertical swing energy capture hydraulic cylinder 302 and the pitch energy capture hydraulic cylinder 403 is in an emergency. The high-pressure chamber enters oil and the low-pressure chamber returns oil, respectively realizing the diving action of the vertical swing buoy 301.

[0059] It can be seen that the upper cabin 104, the bottom cabin 105 and the column 103 are all hollow, the column 103 is located on the center of gravity of the entire frame 100, and the heavy modules are placed in the bottom cabin 105, so that the buoyancy of the entire platform by the seawater is greater than its own gravity, so that it floats on the sea surface. The various structures are arranged reasonably, so that the center of gravity of the platform is lower than the center of buoyancy, preventing the platform from swinging too much or tipping over, and being able to be positioned in the ocean.
