Description

Technical Field

[0001] The present invention relates to the technical field of power generation, and particularly to a wave power generation device. Background Art

[0002] In wave power generation, as the waves rise and fall, the wave power generation device usually has two alternating cycles of intake and exhaust. However, if the generator rotates forward and then backward repeatedly, there is always some energy wasted in overcoming inertia during the direction change, resulting in a reduction in power generation efficiency.

[0003] Therefore, if the airflow formed by intake and exhaust can be unified in the same direction, it will bring an improvement in power generation efficiency. Some current technical solutions are rather complicated. In addition to the increase in device complexity, it will also lead to an increase in the failure rate of the device. Moreover, in order to achieve a unified airflow direction, these solutions usually convert part or all of the gas kinetic energy into another form of energy first, and then convert this form of energy and load it onto the airflow in the unified direction. There is energy loss in this energy conversion itself, resulting in an unsatisfactory improvement in power generation efficiency.

[0040] Optionally, the wave power generation device includes: a floating bin 26 capable of adjusting the proportion of water and air therein, thereby changing the buoyancy of the entire wave power generation device in water.

[0041] Optionally, the wave power generation device includes: a gravity anchor 27 placed at the bottom of the water body, the gravity anchor 27 being connected to the main structure of the wave power generation device through a second towing rope 28.

[0042] Optionally, the wave power generation device includes: a towing system capable of taking in and releasing the second towing rope 28, for providing a pulling force to pull the main structure of the wave power generation device entirely into the water.

[0043] In one embodiment, the second towing rope 28 is a steel wire rope. The gravity anchor 27 and the steel wire rope pull the floating bin 26 underwater to provide bearing capacity support for the whole set of equipment on the water (the whole set of equipment cannot fluctuate with the waves to better capture wave energy).

[0044] In one embodiment, before a typhoon or tsunami comes, the floating bin 26 discharges water to increase the proportion of water in the floating bin 26, the steel wire rope shortens, and the whole set of equipment sinks underwater (it is basically not affected by typhoons and tsunamis at a depth of 50 meters underwater). After the typhoon and tsunami pass, the water in the floating bin 26 is discharged and air is inhaled, and the whole set of equipment floats to the water surface and resumes operation.

[0045] Further, when extreme weather such as typhoons and tsunamis comes, the inlet and exhaust pipe switch of the floating bin 26 is opened to let water in (the switch is closed before the floating bin 26 dives into the water). At the same time, the winch in the towing system shortens the steel wire rope. At the same time, the air inlet channel 3 and the air outlet channel 4 are blocked (there is a preset electric blocking mechanism). The whole power generation system and the floating bin 26 dive together to a depth where they are not affected by disasters such as typhoons and tsunamis, and then the whole system floats up and resumes normal operation. Compared with a fixed support platform on the seabed, such as directly building a platform from the seabed through concrete or steel structure, through the setting of the floating bin 26 and the gravity anchor 27, not only the cost is low, but also it is no longer afraid of being damaged by typhoons and tsunamis, and it can also overcome the problem of difficult construction of support platforms in the deep sea.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
