Movable pulley type wave power generation device

Abstract

The invention discloses a movable pulley type wave power generation device which comprises a buoy and a buoy cover, and a base plate, a tension spring, a tension spring plate guide column, a vibrator, a rotor, a left limiting device, a left movable pulley block, a control cabinet, a top plate, a right movable pulley block, a right limiting device, a vibrator guide column, a stator frame, a stator and a tension spring plate are arranged in the buoy, and the tension spring and a pulley block are arranged in a combined manner, so that the vibrator achieves a resonance effect under the action of waves and tension spring force and achieves an optimal power generation state, the stretching direction of the tension spring is opposite to the vibration direction of the vibrator, space is saved, the elongation of the tension spring is reduced, the limiting device enables the vibrator not to be subjected to the action of tension of the tension spring when the vibrator moves at a high position, and therefore the amplitude of the vibrator achieves the optimal effect, and the power generation efficiency is improved, in addition, the positions of a sliding seat and a clamping ring of the limiting device can be adjusted, so that the stroke of relative movement of the vibrator and the tension spring can be adjusted, namely, the limiting height of the tension of the tension spring can be adjusted according to different sea conditions, the amplitude of the vibrator is optimal, and wave energy is fully recycled.

Description

technical field [0001] The invention relates to the technical field of wave energy power generation, in particular to a movable pulley type wave energy power generation device. Background technique [0002] As the world's energy demand continues to increase, fuel energy is facing depletion, and the use of clean energy has been highly valued. my country has rich marine resources. Wave energy is a renewable clean energy. Oscillatory wave energy power generation The device can convert wave energy into mechanical energy, and mechanical energy into electrical energy. [0003] Under the action of waves, the vibrator in the power generation device vibrates up and down, the coil of the mover cuts the magnetic force line, and the linear generator generates current to generate electricity; in order to improve the efficiency of power generation, extension springs are generally used in oscillating power generation devices at present to make the vibrator vibrate during the vibration proce...

Problems solved by technology

However, the use of extension springs has also caused new problems. When the extension springs are installed below the vibrator and used as compression springs, the collision between the vibrator and the compression springs causes energy loss and reduces the power generation efficiency; when the extension springs are installed above the vibrator When used as an extension spring, the extension spring occupies a large installation height and has a huge structure, which affects the stability of the device; and the vibrator is always subject to the tension of the extension spring in the process of moving up and down, and the fluctuation amplitude of the vibrator is affected. Reduced power generation efficiency
