Embodiment Construction
[0028] Such as figure 1 As shown, this embodiment discloses a group of seawall jumping wave impeller type wave energy generating devices. Four independent wave energy collection and transformation devices are arranged on a section of seawall 14, and each wave energy collection and transformation device is mainly composed of impellers. Mechanism, the wedge-shaped contraction channel 18 connected to the water inlet 16, the drainage corridor 19 connected to the water outlet 17, the gear transmission mechanism and the generator 22 constitute.
[0029] Such as figure 2 As shown, the impeller mechanism includes a cylindrical impeller casing 4, the impeller casing 4 is arranged in the seawall 14, and is firmly connected with the seawall 14 through the foundation base 13. The foundation base 13 is generally mainly made of cement and gravel, and the foundation can also be prefabricated with reinforced concrete in advance, and the impeller casing 4, the wedge shrinkage channel 18 and ...

The invention discloses a seawall jumping-wave impeller type wave-energy generating device group, consisting of at least two wave-energy collecting and converting devices, wherein each wave-energy collecting and converting device comprises an impeller case fixed in a seawall; the impeller case is internally provided with a wheel shaft, and the outer end of the wheel shaft is connected with a generator by a gear transmission mechanism, and the wheel shaft is provided with an impeller with arc concave-surface blades; the inclined upper part of the impeller case is communicated with a wedge-shaped body contractile wave path which is connected with water inlets arranged on the surface of the seawall; the spacings of every two adjacent water inlets are same and the two adjacent water inlets are arranged in a high-low staggered manner; and the inclined lower part of the impeller case is connected with a water discharging gallery which is connected with a water outlets arranged on the surface of the seawall. The seawall jumping-wave impeller type wave-energy generating device group is formed by a plurality of independent wave-energy collecting and converting devices which are arranged ina high-low staggered manner so as to adapt to different sea conditions, can absorb the wave energy generated by wave fluctuation comprehensively and effectively, improve the wave-energy absorption rate in the space-time range, and lead the large-scale development and utilization of the sea-wave energy to be possible.
Description
technical field [0001] The invention relates to the development and application of ocean wave energy in the technical field of renewable energy, in particular to a power generation device utilizing wave energy generated by ocean energy. Background technique [0002] In recent years, driven by the depletion of fossil energy, energy supply security, environmental protection and ecological balance, people have paid more and more attention to the development of new energy. 71% of the earth's surface area is the ocean with huge energy resources, among which wave energy is one of the most abundant energy resources in ocean energy. Utilizing marine energy has become the direction of energy research in the world today, and how to effectively utilize abundant and renewable marine resources is even more important. In 1992, the United Nations listed wave power generation as the top priority in the development of marine renewable energy. Coastal countries attached great importance to i...
