Description
Layered overtopping type wave energy power generation device
FIELD
The invention, involved in the field of wave energy utilization, is an innovative multi-level overtopping wave energy converter with the ability to adapt to the change of sea level independently and higher power generation efficiency.
BACKGROUND
Currently, die main type of high-power shoreline wave energy converters is oscillating water column. Although oscillating water column has advantage of high reliability with few underwater moving parts, the energy conversion efficiency reached ten percent to fifteen percent is so low that the output power of the shoreline device is hard to reach a high level. Moreover, because of the limit of location in shallow water, the wave energy utilization percentage of shoreline device is lower than offshore device in deep water, and meanwhile its development is limited by many other factors such as coastline terrain, tidal range, coast protection and so on.
The adaptation for tidal range of the conventional overtopping wave energy converters is not good, and it has a negative impact on the working waterhead which is very sensitive to the change of water level. This will lead to shorter effective working time, lower conversion efficiency of the device, and make the output power be at a relatively low level. Most overtopping wave energy converters keep the water head to generate electricity on the condition that the wave overtopping rate exceeds the rated outflow volume, which means conventional devices have a high requirement on incident wave. Because of the randomness and irregularity of incident wave, the way of keeping water head mentioned above only works well when incident wave amplitude is large. Therefore, these overtopping devices are widely used in the areas where wave energy level is high, and utilization efficiency of the device become lower when used in areas with short-period and small-amplitude waves.
An invented overtopping wave energy converter (patent NO. 201010575362.5) consists of a single reservoir stmcture, adapts badly to the tidal range of die surrounding sea, and has a high requirement on die incident wave, which results in a lower degree of efficiency. Besides, it is a floating device located in deep water where the living environment is extremely bad. Therefore, the reliability of working in marine environment and die difficulty to deploy and recycle the device are the tough tasks to be solved.
SUMMARY
To solve the technical problems outlined above, this invention proposes a multi-level overtopping wave energy converter with the ability to adapt to the change of sea level independently and higher power generation efficiency.
Technical scheme of the invention is a multi-level overtopping wave energy converter for generating electricity, comprising an energy storage system, an auto-open/close system, a hydroelectric generating system and a working platform.
To be specific, the energy storage system is a multi-level structure, including an upper reservoir and a lower reservoir, and the structure is in shape of a half hollow frustum of a cone. The water inlet-A is set at the top of the upper reservoir; there is a half-ring gap, which is the water inlet-B of the lower reservoir, between the upper reservoir and lower reservoir; and the water inlet-B is set at the bottom of the lower reservoir.
The auto-open/close system comprising: a driving motor, a screw jack, three cover plates, the duct-A and a controller. Cover plate-A and cover plate-B which are used to closing the water outlet-B are fixed on the two ends of duct-A; water outlet-A connected with duct-A is set on the cover plate A; cover plate-Cis set on the water outlet-A; and duct-A is located between the upper reservoir and die lower reservoir. The screw jack comprises the screw jack-A and the screw jack-B, driving motor is connected with screw jack-A and screw jack-B by the coupling; lifting rod-A of screw jack-A is connected with cover plate-C; lifting rod-B of screw jack-B is connected with cover plate-A, and controller is connected with driving motor.
The hydroelectric generating system comprises the duct-B, hydraulic turbine and the generator. The upper end of the duct-B is connected with the water outlet-Band the lower end of the duct-B stretches into the bottom of the multi-level overtopping wave energy converter; there is a Z-type bend at the upper end of the duct-B and a L-type bend at the lower end of the duct-B; the L-type bend stretches into the back of the multi-level overtopping wave energy converter; die generator is installed on the working platform; die hydraulic turbine is set on the turning of the L-type bend; and the wheel axle of the hydraulic turbine is connected with the output shaft of the generator.
The working platform is installed at the top of the water inlet-A of the energy storage system.
Several wedge-shaped ramps which are evenly divided by guide vanes arc set on the outside ramps of the upper reservoir and lower reservoir.
The ramp slope is 2:3, which is suitable for wave climbing and hiking.
The shape of the guide vane is quadrangle, generally trapezoid The inner tide gauges are set both in the upper reservoir and lower reservoir; the outer tide gauge is set outside of the multi-level overtopping wave energy converter; both inner tide gauge and outer tide gauge have water level sensors which are connected with the controller of the auto open/close system.
The auto-open/close system, the top of screw jack-A and lifting rod-A are all installed on the working platform; the lifting rod-A of screw jack-A is connected to the cover plate-C through the working platform; and the lifting rod-B of screw jack-B is connected to the cover plate-A through the working platform.
There are two screw jacks B symmetrically disposed in the left and right sides of the coupling respectively. The hydroelectric generating system includes the storage battery that connected to the generator on the working platform.
The hydraulic turbine is axial flow water turbine.
The multi-stage overtopping wave energy converter included support system which is consisted by the foundation and piles. And the foundation is fixed in the bedrock, the piles distributed evenly on the foundation while one side is connected to the foundation and the other side is connected to the bottom of the lower reservoir from the energy storage system.
The working platform is fixed with the upper reservoir by the supports and there is a protective cover on the working platform to protect the equipment.
Outside ramps of the energy storage system can be used as the breakwater or revetment. For instance, the overtopping wave energy converter can be laid at the end of the breakwater to make the passive energy dissipation of the breakwater become the active energy absorption of the converter. On one hand, the wave load on the marine structure is reduced and the reliability is increased. On the other hand, the wave energy converter can provide electricity support for the lighthouse straightly, which italic the green power supply.
The guide vanes introduced above can prevent wave slipping off to two sides during wave run-up, capture wave energy as much as possible, and furthermore help to increase the wave height. It is found that the device without guide vanes only have wave overtopping into the reservoir from the forward direction generally. Wave slips off to two sides seriously after running up along ramp, and there is not much water overtopping into the reservoir each time, therefore it takes a long time to fill up the whole reservoir. Besides, it is easy to break when wave runs up, resulting in large energy loss. By using guide vanes, wave overtopping rate from forward direction is effectively increased by 20-30%, the amount of backflow from side ramp is reduced, and the concentration of wave energy in the back of the device is decreased.
The auto-open/close system connects upper reservoir and lower reservoir of energy storage system. When the auto-open/close system is closed, upper and lower reservoir start to store water together When reservoirs are full of water, the upper reservoir needs to release water to generate electricity. In this state, cover plate B is opened by screw jack (closed hi delayed time), thus the upper reservoir is connected to duct B by duct A, and release water. Meanwhile, as the lower reservoir is (almost) in the submerged condition, the upper and lower reservoirs do not have straight connection, and water in upper reservoir cannot return to the sea via lower reservoir. When the lower reservoir needs to release water to generate electricity, cover plate B. cover plate A and duct A arc all lifted by screw jack (closed in delayed time). Water outlet B of the lower reservoir is connected to duct B, and water in lower reservoir is released. Meanwhile, the upper and lower reservoirs do not have straight connection either. By this way, two reservoirs are able to store water independently and release water by sharing duct B. The auto-open/close system can ensure that outflow impulses and drives the turbine at a rated water head each time, which will effectively improve the level of generated output and energy conversion efficiency.
The design of Z-shaped bend is mainly for avoiding the conflict between the hydroelectric generating system and auto-open/close system on spatial arrangement. Therefore, the generator can be easily installed on the working platform. The end of L-shaped bend is stretched to the backside of wave energy converter's bottom. This is to avoid backflow caused by wave or ocean current affecting the normal movement of the turbine.
The support system comprises column piles which are embedded in reinforced concrete block on bedrock. The whole structure has good integrity and high stability. It is easy for ships to berth alongside, and convenient to maintain and repair. Comparing with the caisson, structure of piles can be used in area of deep water without shoreline resource occupation, primary energy consumption, flue gas, noise, dust and ham) to environment.
The invention has several beneficial effects. Firstly, the converter introduces a multi-level energy storage system that can work in different water level and incident wave. Therefore, it solves the problem of adapting the tidal range independently and significantly increases the total and energy conversion output and generated power Secondly, the converter introduces an auto-open/close system that can control reservoirs to release water only when fully loaded. Although the generation is intermittent, it can guarantee the ideal water head for generation and a high level of generating efficiency. Finally, the multi-level overtopping wave energy converter can be installed on breakwaters and offshore.
