Technical Field

The invention relates to the field of ocean power generation, in particular to an ocean energy wave-current integrated power generation device.

Background

Tidal current energy and wave energy are used as two forms of ocean energy resources with the most development potential, the content of the resources is very rich, and according to statistics, the annual average power of the coastal theory waves in China is about 1.3 × 10⁷kW, the theoretical average power of tidal current energy resource storage amount can reach about 1.4 × 10⁷kW. Therefore, the wave energy and tidal current energy have wide development and utilization prospects.

Tidal current energy is water flow caused by tide, is mostly arranged in a water channel or gulf mouth between a shore, a strait and an island, changes the size and the direction twice a day along with the fluctuation of the tide, and changes stably and regularly; wave energy refers to kinetic energy and potential energy of ocean surface waves, the energy of the waves is in direct proportion to the square of wave height, the motion period of the waves and the width of a wave-facing surface, and the wave energy is the most unstable energy in ocean energy.

At present, the wave energy power generation device has more energy conversion links, the device structure is complex, and the components are various. The electric energy conversion mostly adopts a high-speed rotating generator, the typical wave speed of waves is 0.5-2 m/s, and in order to improve the low speed to drive the high-speed rotating generator, a hydraulic or pneumatic device and a matched gear box structure are generally adopted, so that the electric energy conversion has the advantages of heavy volume, high investment, poor reliability and low efficiency. In addition, in order to capture wave energy to the maximum extent, a capturing floater of the wave energy power generation device is usually huge, floats with the wave when exposed on the sea surface, and the floating kinetic energy of the floater is transmitted to a shore base or a larger floating platform through a lever principle, so that the weakest link in the wave energy power generation device is formed. Under severe environment, the lever is easy to damage and break under the impact of heavy waves, so that the energy-obtaining floater is separated from a shore base or a platform, sinks into the sea bottom or drifts away along with the flow, and cannot be recovered.

The tidal current energy power generation device is generally characterized in that an impeller is placed in seawater, and the flowing seawater is used for pushing blades of the impeller to rotate so as to generate power. Because the tidal current has directionality, the direction is changed twice every day along with the fluctuation of the tide, and the direction of the impeller needs to be continuously changed by the tidal current energy power generation structure of the horizontal shaft according to the change of the flow direction of the tidal current, so that the capture efficiency is ensured. Therefore, the structure includes a direction-adjusting mechanical component or a dynamic seal component, and is easily damaged by repeated rotation, thereby reducing reliability. The vertical axis tidal current energy power generation structure does not need convection, can capture tidal current in any direction to carry out rotary power generation after being put into water, and has higher reliability than a horizontal axis. However, the distribution position is perpendicular to the tidal current direction, the vertical axis blades are inclined under the action of fluid impact, the force on the leading surfaces of the blades is a tangential component of the fluid impact force, the working efficiency of the rotating wheel is greatly reduced, and the power generation capacity is reduced. Although the two ends of the vertical shaft device can be fixed by a base dam building mode and the like to solve the inclination problem, the mode relates to ocean engineering, the investment is huge, the cost is high, and certain damage can be brought to the ocean environment.

With the increasing maturity of ocean energy development technology, the construction cost of expensive infrastructure becomes a big bottleneck for the development and utilization of ocean energy. In addition, the poor viability of the device in harsh sea conditions is another major obstacle that hinders its commercial operation. Therefore, the key to the development and utilization of ocean energy is to reduce the construction cost of the ocean energy device and improve the viability of the ocean energy device under severe sea conditions. And diversification and comprehensive utilization are effective ways for saving the construction cost of ocean energy equipment.

The working principle and the working process of the invention are as follows:

the invention needs to be assembled before use, has flexible assembly mode and can be divided into onshore assembly and offshore assembly. When the assembly is carried out on land, as shown in fig. 1, the outer frame is vertically placed, the tidal current energy power generation assembly is placed into the outer frame from the upper end mounting opening of the outer frame through lifting equipment, and the tidal current energy power generation assembly falls to the bottom supporting plane along the left inner side rail and the right inner side rail of the outer frame. After tidal current energy power generation is gradually installed, the wave energy power generation assembly is placed into the outer frame from the installation opening in the upper end of the outer frame through hoisting equipment, and when a linear motor end cover in the wave energy power generation assembly is in contact alignment with the upper portion of the outer frame, the linear motor end cover is fixed with the outer frame through bolts. After the assembly is completed, the assembled device is vertically immersed into water according to required electric equipment and electricity utilization environment. When the wave energy power generation assembly enters water, the front face and the rear face of the lower layer of the outer frame which is designed to be fully open are opposite to the tidal current direction, the tidal current energy power generation assembly at the bottom layer is completely submerged, and the floater of the wave energy power generation assembly at the upper layer floats on the water surface and can freely move up and down, as shown in fig. 2. Finally, the outer frame of the device is fixed with the equipment needing electricity, such as wharfs, ships, buoys and the like, by adopting the modes of binding, fastening, hanging and the like.

When the offshore installation scheme is adopted, the outer frame is firstly immersed into water, and when the outer frame enters the water, on one hand, the front and back surfaces of the lower layer of the outer frame are ensured to be opposite to the tidal current direction by adopting a fully-open design, and on the other hand, the water entry depth of the outer frame is determined according to the sizes of the wave energy power generation assembly and the tidal current energy power generation assembly. The principle of determination is shown in fig. 2, namely, the tidal current energy power generation assembly on the bottom layer can be ensured to be completely submerged into water after being placed into the frame, and meanwhile, after the wave energy power generation assembly on the upper layer is installed, the floater can float on the water surface and can freely move up and down. After the underwater depth of the outer frame is determined, the outer frame and equipment needing power utilization, such as a wharf, a ship, a buoy and the like, are fixed in a binding, fastening or hanging mode. After the outer frame is fixed, the tidal current energy power generation assembly and the wave energy power generation assembly are sequentially installed into the outer frame through hoisting equipment according to a land installation mode, and the linear motor end cover in the wave energy power generation assembly is fixed with the outer frame.

When the invention works, the outer frame is fixed on the side surfaces of electric equipment such as wharfs, buoys, ships and the like, the upper part of the outer frame is positioned above the water surface, and the lower part of the outer frame is positioned below the water surface, so that the outer frame plays a role of fixing and supporting; the floater of the wave energy power generation assembly on the upper layer in the outer frame floats up and down along with water surface waves to push the connecting rod to move up and down, so that the linear generator is driven to convert wave energy into electric energy; blades of the tidal current energy power generation assembly positioned at the lower layer in the outer frame rotate under the driving of tidal current energy, and then the blades drive the rotary generator to convert the tidal current energy into electric energy. When needs carry out simple maintenance, the maintainer can utilize the parallel strengthening rib on the left side of outer frame or right side as the vertical ladder, scrambles, inspects or clears up the rubbish on water around the device. When the wave energy power generation assembly is required to be overhauled, the wave energy power generation assembly on the upper layer and the tidal current power generation assembly on the lower layer can be directly and sequentially lifted out without moving an outer frame, and the overhaul is carried out.

The traditional wave-flow integrated power generation device structure is that a floating large floating platform or a breakwater is usually built, then the traditional wave energy power generation device is installed on the side surface of the floating platform, and the tidal current energy power generation device is suspended at the bottom of the floating platform. On one hand, the integrated device still needs to solve the problems of complex marine engineering infrastructure and large-scale floating platform offshore consignment anchoring; on the other hand, the integrated device is only used for simply arraying and stacking the wave energy power generation device and the tidal current energy power generation device, and does not solve the reliability problem of the wave energy power generation device and the tidal current energy power generation device, and the problems of easiness in damage, easiness in overturning, poor reliability, low power generation efficiency and the like of the traditional wave energy power generation device and the traditional tidal current energy power generation device still exist.

The wave energy power generation assembly and the tidal current energy power generation assembly are innovatively optimized and improved, are integrated into a whole through an outer frame structure, are small in size, can be conveniently fixed on the side surfaces of electrical equipment such as wharfs, buoys and ships, and solve the anchoring problem of the device. Meanwhile, the wave energy power generation assembly and the tidal current energy power generation assembly of the invention completely work in the outer frame, which does not affect the capture of wave energy and tidal current energy, and simultaneously play a role in protecting and supporting the power generation device, thereby avoiding the device from tilting or being damaged, and improving the power generation efficiency and reliability of the device.

A plurality of reinforcing ribs welded on the left side and the right side of the outer frame in parallel form a vertical ladder structure, so that maintenance personnel can conveniently climb up and down to overhaul; the outer frame does not need to move after being fixed, the guide rails on the left inner side and the right inner side are designed, and the guide rails directly penetrate through the bottom supporting platform from the top mounting hole, so that the wave energy power generation assembly and the tidal current energy power generation assembly can be conveniently positioned, mounted and dismounted; the front side and the rear side are divided into two layers, and the lower layer is of a fully-open structure, so that the lower layer water flow can directly impact the tidal current energy power generation device, the flow speed cannot be influenced, and the power generation efficiency is reduced; the front and the back of the upper layer are provided with the protection ribs, wave floating in the outer frame is not influenced, and the floater of the wave power generation assembly can be enclosed in the outer frame, so that the floater loss caused by the breakage of the connecting rod is avoided, and the recovery is facilitated.

The wave energy power generation assembly is partially different from the traditional wave energy power generation device. On one hand, the wave energy power generation assembly adopts a power generation mode that the floater directly drives the linear generator rotor through the connecting rod to directly convert the up-and-down movement of the floater into electric energy, and has higher reliability because no conversion gear box, dynamic seal and other parts are arranged; a lever bending part is not arranged, so that the damage probability of the connecting rod is greatly reduced; meanwhile, the length of the connecting rod between the floater and the linear motor can be flexibly adjusted according to practical application occasions and wave conditions, and the wave energy capturing efficiency is guaranteed to be maximized. On the other hand, the end cover structure of the linear motor is innovatively improved, a special structural design is carried out according to the structural size of the outer frame, the linear motor and the outer frame can be firmly fixed together, the stability of the power generation device is guaranteed, the linear motor can be conveniently disassembled, and the maintainability of the power generation device is guaranteed.

The tidal current energy power generation assembly is innovatively designed in the inner frame, the inner frame can be matched with the track of the outer frame, the tidal current energy power generation assembly can be directly installed in place along the track from the installation opening on the premise of not moving the outer frame, and the operation is convenient; the tidal current energy generator and the blades are arranged in the inner frame, on one hand, the upper plane and the lower plane of the inner frame simultaneously restrain two ends of a supporting shaft of the tidal current energy generator, and the power generation assembly is prevented from overturning after being impacted by water flow; on the other hand, the inner frame plays a role in protecting blades and motors for tidal current energy power generation, and the blades or the motors are prevented from being damaged due to collision in the transportation or installation process.
