Problems solved by technology
[0003] For example, the Chinese patent document with the publication number CN107524556A discloses a new type of high-efficiency float and pull-wire power generation device and power generation method, but there are the following problems: 1. The design of the float structure leads to low utilization of captured energy; 2. The vibration of the float and the wave The frequency difference between them is large, resulting in low efficiency of the floater to capture wave energy; 3. Low power generation efficiency and low energy utilization rate

The invention relates to a sea swing-type wave-proof power generation device. A supporting part is fixedly arranged in the position between adjacent wave-proof blocks of a wave-proof dam, a power generation module is fixedly arranged on the supporting part, and the power generation module is connected with a floater module through a transmission module which is arranged downwards in a dropping mode; the floater module comprises an olive-shaped floater, the floater is internally provided with a liquid level sensor and an automatic drainage pump, a drainage port is formed in the bottom of the floater, and the automatic drainage pump conducts automatic drainage according to liquid level signals of the liquid level sensor to control the ballast water yield in the floater in a set range; by means of the ballast water yield, the floater module has a set draft depth, and by means of the draft depth, the natural efficiency of the floater module is equal to or close to that of sea waves. According to the device, by actively adjusting the ballast water yield, variable weight design is conducted on the floater module, thus the set draft depth is obtained, by means of the draft depth, the natural efficiency of the floater module reaches that of the sea waves, thus resonance is achieved, and the wave energy power generation efficiency is improved.
Description
technical field [0001] The present invention relates to a kind of wave energy generating device, specifically, is a kind of sea swing type anti-wave generating device. Background technique [0002] Nowadays, the floating structure wave power generation devices that are widely used mainly rely on the floating structure under the action of waves to drive the motor to generate electricity. The movement of this type of device can be the absolute movement of the oscillating floating body relative to the fixed reference object, or the movement between two floating bodies. relative motion between them. The wave energy is converted into the kinetic energy of the oscillating floating body, which then drives the motor to rotate, thereby generating electrical energy. [0003] For example, the Chinese patent document with the publication number CN107524556A discloses a new type of high-efficiency float and pull-wire power generation device and power generation method, but there are the...
