Description

A wave power generation device capable of resisting storm impact

technical field

The utility model patent relates to a wave power generation device capable of resisting storm impact, which belongs to the mechanical field.

Background technique

Although a wave is just the ups and downs of seawater particles in situ, its movement energy is very huge. It is estimated that the wave energy on a square kilometer of sea surface can reach a power of 250,000 kilowatts. Because of the huge energy contained in it, the destructive power of waves is also amazing. Huge waves have thrown dozens of tons of boulders onto the shore, and have also pushed 10,000-ton ships to the shore. In the 1950s, there was a shipwreck of an American giant ship that was broken in half by large waves in Italian waters. How to harness the waves for the benefit of mankind has been the dream of people for hundreds of years. At present, there are more than 1,500 patents related to wave energy technology in the world, and dozens of wave energy utilization technologies are under development. Some have already entered the state of power generation application. However, due to the late start of the technology and still facing some major problems, the application of wave energy is far lower than that of wind energy and solar energy. Not many can really stand the test of waves, and many power generation devices have been damaged ( shore) or sunk (ship). Therefore, a wave power generation device capable of resisting storm impact is proposed.

The utility model is designed to solve the impact damage problem existing in the above-mentioned wave power generation device. Effective and reliable power generation device.

Utility model content

The technical problem to be solved by this utility model patent is to provide a wave power generation device that can resist the impact of storms. service life of the generator. The purpose of this utility model patent is to provide an effective and reliable power generation device for the utilization and development of wave energy.

In order to solve the above problems, the utility model patent is realized as follows: the utility model patent mainly includes wave energy conversion buoys, guide columns, support platforms, large hydraulic motor-driven power generation devices, hydraulic cylinders, small hydraulic motor-driven power generation devices and wave power generation One of its characteristics is that the hydraulic cylinder, the large hydraulic motor-driven power generation device and the small hydraulic motor-driven power generation device are all installed in the wave power generation chamber, and only the piston rod of the hydraulic cylinder is connected to the wave energy conversion buoy through the support platform; The second feature is that the top of the guide column is fixedly connected with the support platform, and its column is slidingly connected with the wave energy conversion buoy; the third feature is that the rodless chamber of the hydraulic cylinder is connected with the large hydraulic motor-driven power generation device through the hydraulic pipeline , and its rod cavity is connected with a small hydraulic motor to drive a power generation device through a hydraulic pipeline.

The working principle of the storm-resistant wave power generation device is: when the wave rises, the wave pushes the wave energy conversion buoy to move upward along the guide column, and then drives the piston rod of the hydraulic cylinder to rise, so that the oil in the rodless chamber of the hydraulic cylinder It is discharged and enters the large hydraulic motor to drive the power generating device to generate electricity through the hydraulic pipeline. When the wave descends, the wave energy conversion buoy descends along the guide column by its own weight, and then drives the piston rod of the hydraulic cylinder to descend, so that the oil in the rod cavity of the hydraulic cylinder is discharged, and the small hydraulic motor drives the power generation device through the hydraulic pipeline to generate electricity. On the one hand, because the wave energy conversion buoy only moves up and down along the guide column, the anchoring system of the conventional wave power generation device is omitted, and the impact of the storm can be resisted. On the other hand, since the hydraulic cylinder, the large hydraulic motor-driven power generation device and the small hydraulic motor-driven power generation device are all installed in the wave power generation chamber, only the piston rod of the hydraulic cylinder is connected to the wave energy conversion buoy through the support platform, so that the hydraulic system components Only the piston rod is in contact with seawater, and the rest are located above the closed sea surface, so the equipment and components of the system are effectively protected, and the corrosion effects of sea organisms, seawater and salt spray on the power generation device are avoided.

The utility model can effectively resist the impact of the storm on the wave power generation device, avoid the corrosion effects of marine organisms, sea water and salt spray on the power generation device, facilitate maintenance, reduce costs, and greatly improve the service life of the power generation device. The power generation device does not leak any pollutants, which can effectively protect the marine environment. The device has the characteristics of simple and reliable structure and excellent operational performance. The wave energy conversion technology of the utility model has strong storm resistance and corrosion resistance, is particularly suitable for the development and application of large-scale wave power generation devices, and has very high promotion and application value.
