Description

Technical Field

[0001] This utility model relates to the field of marine energy utilization and renewable energy utilization technology, and in particular to an omnidirectional water flow metamaterial energy focusing device. Background Technology

[0002] Against the backdrop of ever-increasing energy demand and a growing need for clean energy, hydropower, as an important renewable energy source, has received widespread attention for its effective utilization. Traditional hydro turbines have certain limitations in capturing energy from water flow, particularly in their strict requirements regarding flow direction and velocity. In low-velocity or complex flow environments, the energy conversion efficiency of hydro turbines is relatively low.

[0003] Existing equipment lacks effective means for concentrating and optimizing the energy of water flow, making it difficult to fully tap the potential energy of water flow.

[0004] To this end, we propose an omnidirectional water flow metamaterial energy focusing device. Utility Model Content

[0005] To address the shortcomings of existing production technologies, the applicant provides an omnidirectional water flow metamaterial energy-concentrating device. This device, through an energy-concentrating array structure, achieves efficient concentration and optimized utilization of water flow energy, reduces the starting water flow speed requirements for hydro-generators, improves the energy conversion efficiency of hydro-generators under different water flow conditions, and thus enhances the overall performance and stability of the power generation system.

[0006] The technical solution adopted in this utility model is as follows:

[0007] An omnidirectional water flow metamaterial energy focusing device, comprising:

[0008] The power generation system includes a hydro-generator, which is fixed to the top of a support column, which is fixed to an underwater base.

[0009] The energy-concentrating array structure includes a support frame and multiple energy-concentrating structures. The support frame is fixedly connected to the support column, and the multiple energy-concentrating structures are fixed on the support frame.

[0010] Each energy-concentrating structure includes multiple energy-concentrating units, and each energy-concentrating structure is arranged vertically along the normal direction of the supporting column.

[0011] The energy-concentrating unit has a columnar structure, and its cross-section is shaped like the NACA0012 wing, with the tip of the energy-concentrating unit pointing towards the supporting column.

[0012] Its further features are:

[0013] The support structure of the energy-concentrating array includes multiple normal fixing supports and multiple annular fixing supports. The normal fixing supports are arranged along the normal direction of the support column and are fixedly connected to the support column. The multiple annular fixing supports are fixed at intervals on the normal fixing supports.

[0014] It also includes an anchoring system, which consists of a mooring point, an anchor chain, and an anchor. The anchor is fixed to the underwater base, the mooring point is fixed to the outermost ring-shaped support, one end of the anchor chain is fixedly connected to the mooring point, and the other end of the anchor chain is fixedly connected to the anchor.

[0015] The underwater substrate includes the riverbed and the seabed.

[0016] The energy-focusing unit is composed of fluid metamaterials.

[0017] The support column is fixed to the underwater base via a base, the support column is fixed to the top of the base, and the base is fixed to the underwater base.

[0018] The surface of the normal fixing bracket, the ring fixing bracket, the support column, and the base are all treated with corrosion resistance.

[0019] The hydro-generator is a vertical-axis hydro-turbine.

[0020] The support column is equipped with power lines. One end of the power lines is connected to the hydro-generator, and the other end is connected to the underwater cable for power transmission after power generation.

[0021] The height of the energy-concentrating unit is more than twice the height of the hydro-generator.

[0022] The beneficial effects of this utility model are as follows:

[0023] This utility model has a compact and reasonable structure and is easy to operate. When in operation, the water flow in the river or ocean passes through the energy-concentrating array structure, which can improve the energy capture efficiency. Through the energy-concentrating array structure, the local water flow energy density can be significantly increased compared to the incident water flow. The flow velocity increases and converges at the water turbine generator at the center of the array to reach the maximum flow velocity. The water turbine generator converts the potential energy of the water flow into electrical energy. The electrical energy is transmitted back to the land for use through the power lines of the support column and the underwater cable, thereby increasing the usable energy of the water turbine generator 4 and improving the power generation power of the power generation system.

[0024] In addition, this utility model also has the following advantages:

[0025] (1) It can broaden the scope of water flow application, reduce the starting water flow speed of the water turbine generator, and enable the device to work effectively in environments with low water flow velocity or complex and varied water flow direction, greatly expanding the scenarios and time range of water energy utilization.

[0026] (2) It can enhance system stability, omnidirectional water flow collection capability and optimized connection structure, so that the hydro generator can maintain a relatively stable working state under different water flow conditions, reduce the problem of unstable energy output caused by water flow fluctuations, and improve the reliability and stability of the entire power generation system.
