Wave energy power generation device arranged at dam

Abstract

The invention discloses a wave power generation device arranged at a dam. The wave power generation device comprises an underwater base, a swing rod, a floater, a connecting rope and a power generation assembly arranged on the bank. The power generation assembly comprises a generator shell, a center shaft, a linear generator stator, a linear generator rotor and a damping spring. The linear generator rotor fixedly sleeves the central shaft and is located in a cavity of the linear generator stator, one end of the central shaft is connected with the connecting rope, the other end of the central shaft is connected with one end of the damping spring, and the other end of the damping spring is fixedly connected with the inner wall of the motor shell; the underwater base is fixed to the seabed, the lower portion of the swing rod is hinged to the underwater base, and the floater is movably arranged on the swing rod in a sleeving mode and connected with the other end of the connecting rope. The device is simple in structure, the linear generator is directly driven, and energy loss is reduced; the swing rod can swing around the underwater base, so that the sliding range of the floater on the swing rod is increased, and the energy extraction efficiency is improved; the power generation chamber is located ashore and is easy to maintain.

Description

technical field [0001] The invention belongs to the technical field of wave energy generating devices, and in particular relates to a wave energy generating device arranged at a dam. Background technique [0002] Wave energy is a clean and renewable energy with huge energy. Its rational development and utilization are of great significance to alleviate the energy crisis and improve environmental pollution. [0003] Most of the existing wave energy generation devices are installed in the ocean. Due to the undulation instability of waves and the difference in wave height, the efficiency of wave energy generation is low; Resulting in high later maintenance costs. Near the coast or breakwater, the wave hits the dam and reflects, forming a standing wave in front of the shore or breakwater, the wave height increases, and the wave energy is transmitted back after reflection, increasing the number of waves. If a power generation device can be installed here, The power generation e...
