Abstract

The invention discloses a device for collecting wave energy by using wave flowing water pressure and belongs to the technical field of fluid machines for energy collection, energy conversion and efficient wave energy utilization. The structure comprises a rigid piston, multi-stage hydraulic collection cylinders, check valves, a loop pipeline, a turbine generator, a spraying pipe and an energy accumulator. The multi-stage hydraulic collection cylinders are connected in series, and the corresponding check valve is arranged between every two hydraulic collection cylinders; the hydraulic collection cylinders on the two sides of the system communicate with each other through the loop pipeline; the loop pipeline is sequentially provided with the energy accumulator, the spraying pipe and the turbine generator in the flowing direction of work liquid; and the work liquid flows out of the hydraulic collection cylinder on one side of the system, the hydraulic energy is collected after the work liquid passes through the energy accumulator, the work liquid reaches the turbine generator, and the wave energy is converted into the electric energy. The device for collecting the wave energy by usingthe wave flowing water pressure overcomes the defect of traditional low-efficiency wave energy collection, the device is placed on the seabed, water surface navigation is not affected, the structureis simple and reliable, the seabed wave load is small, and structural damage is not likely to be caused.

Description

technical field [0001] The invention belongs to the technical field of fluid machinery for energy collection, energy conversion and efficient use of wave energy, and relates to a device for collecting wave energy by using wave dynamic water pressure. Background technique [0002] The increasingly serious energy crisis and environmental pollution have prompted the society to pay more and more attention to the development and utilization of new energy in order to maintain development. New energy has been widely used for its renewable, environmentally friendly, and low-pollution characteristics. The current technologies related to new energy mainly include Nuclear energy, wind energy, solar energy, ocean energy, wave energy, etc. [0003] Wave energy is generated by the wind transferring energy to the ocean. Wave energy appears in the form of mechanical energy. It is the largest energy in ocean energy and the energy with better quality, but it is also very unstable energy. Wit...
