Description
Technical Field
The utility model belongs to the technical field of the breakwater, concretely relates to integrated multiple ocean power generation facility's comb-type breakwater unit and system.
Background
With the increasing tension of world energy, ocean energy is a new energy source and attracts people's attention with its unique advantages and strategic position. According to statistics, the ocean energy accounts for 70% of the total energy of the whole world, wherein the tidal current energy is about 50 hundred million kW, the wave energy is about 25 hundred million KW, and the atmospheric energy is 1017 KW. Meanwhile, ocean energy is a main way for solving the energy shortage of coastal areas and islands in China. China is in coastal areas with concentrated population, dense assets and developed social and economic benefits. Coastal islands are new socioeconomic bodies or national defense sentinels under development or developed. The lack of electric power becomes a key factor for restricting the social and economic development of coastal areas, particularly islands in China. The construction of an ocean power generation system suitable for coastal areas and islands according to local conditions is one of the main ways of supplementing coastal power shortage and solving the problems of residents on islands and military power utilization.
The comb-type breakwater is a novel breakwater form, and is characterized in that a traditional square caisson is taken out according to a certain proportion and replaced by a caisson wing plate, and a comb-tooth-shaped vertical breakwater is formed on a plane. The broken part of the prefabricated breast wall forms a wave-dissipating chamber with the prefabricated breast wall, has the advantages of wave gathering, wave dissipating, flow penetration, light reduction of foundation bearing capacity and the like, and has been built into a demonstration project in a large-scale continuous kiln bay harbor area. Comb-type breakwater pterygoid lamina and front wall are not in a plane, and the interval between the two makes the wave power arrive the peak value of breakwater crisscross, has reduced the total horizontal wave power that the breakwater received, has both done the dead weight and has alleviateed and avoided the dead weight to alleviate the adverse effect who brings, keeps stable in structure. The hydrodynamic characteristics of the comb breakwater wave dissipation chamber are complex, but theoretical analysis can prove that the wave amplitude of the position is increased relative to the position of the front wall, and a strong wave gathering effect is achieved; research shows that when the draught of the rear wing plate is larger than that of the front wing plate, the resonance wave height in the wave dissipation chamber can be increased.
The oscillating float type wave energy power generation device is a wave energy utilization device which drives a float to move up and down through waves and converts the relative movement mechanical energy of the float into electric energy, and has practical application at home and abroad. However, the fixing mode still has certain problems: the small-sized power generation device can directly float on the water surface, but the power generation efficiency is not high, and the large-sized power generation device has two anchoring modes, namely, the device is suspended in the sea through a traction rope, but the device is greatly influenced by the ocean current and is not stable enough; the other is directly fixed on the seabed, the mode is only suitable for the shallow sea field, the condition suitable for fixing is created on the seabed when the water depth is deeper, the cost is relatively high, and the satisfactory power generation cost performance is difficult to achieve. Therefore, the device has higher requirements on the stability and the reliability of the structure in a severe service environment, and the advantage of high power generation efficiency of the device is limited.
The oscillating water column type wave power generation device utilizes air as a conversion medium, the collection of energy is completed through an air chamber, the lower opening of the air chamber is communicated with seawater under water, and the upper opening of the air chamber is communicated with the atmosphere. The water column in the air chamber does up-and-down reciprocating motion under the action of waves, the action of the water column is similar to that of a piston, the continuous motion of the water column causes the air column at the upper part of the free surface of the water column to generate oscillating motion, air flows through a reciprocating turbine at an air outlet above the air chamber, a turbine rotating shaft is connected with a generator, and the turbine can be driven to rotate by utilizing compressed air flow and drive the generator to generate electricity. The oscillating water column type wave power generation device adopts air to transfer energy, so that the direct impact of waves on a power generation system can be avoided, the working time of the power generation system is prolonged, and the power generation cost is reduced.
The hydro-turbine type power generation device directly drives the generator set by utilizing the tide to convert the tide energy into the electric energy, and has simple structure and high power generation efficiency; however, the basic fixing cost is high, the working tide needs other devices for constraint, and the satisfactory cost performance of power generation cannot be achieved. The hydro-turbine type power generation device is integrated in the middle of the comb type permeable and contractible water channel breakwater caisson, so that the cost for independently building a foundation of the hydro-turbine type power generation device is saved, and the comb type permeable and contractible water channel breakwater structure is utilized to restrain the tidal current of ports and exits to guarantee the maximization of the power generation efficiency.
The wind power generation device utilizes wind power to push the wind paddle blades, and converts wind energy into mechanical energy; and the blade drives the generator set to convert mechanical energy into electric energy, so that the conversion from wind energy to electric energy is realized. In consideration of the advantages of stable offshore wind, high fan utilization rate, large single machine installed capacity and no land resource occupation, the development of wind power gradually moves to the ocean era, but the installation basic cost of the wind power generation device limits the popularization of the wind power generation device in the ocean. The comb-type breakwater is combined with the fan for power generation, so that the stability and reliability of the fan are improved to a great extent, wind energy can be reduced, the wave amplitude of wind waves is reduced, and the stability of the water surface in a harbor area is ensured.
