Description

Wave Power Device

technical field

The utility model relates to the field of power generation, in particular to a wave power generation device.

Background technique

The depletion of traditional energy sources and the deterioration of environmental pollution make it urgent to develop new energy sources. Environmentally clean and renewable energy sources such as solar energy, wind energy, and wave energy power generation are made into micro power supplies to provide electrical energy for sensor nodes, and have increasingly attracted widespread attention from all walks of life. Compared with wind energy and solar energy technology, wave energy power generation technology is more than ten years behind. However, wave energy has its unique advantages. The energy density of wave energy is high, which is 4 to 30 times that of wind energy. Compared with solar energy, wave energy is not affected by the weather. The wave power generation power supply is a power supply made of wave power generation, which has many advantages:

1. Wave energy is widely distributed and has huge reserves, which can be harvested locally;

2. The wave power generation device is less affected by sea conditions and climate.

The interaction of wind and sea surface produces waves, and wave energy is one of the water energy resources expressed in the form of kinetic energy. In 1977, someone calculated the ocean waves with an average height of 1 meter and a period of 1 second in the world's oceans. It was believed that the global wave energy power is about 70 billion kilowatts, of which about 2.5 billion kilowatts can be developed and utilized, which is similar to tidal energy. There is such a wealth of energy in the waves, such as converting the kinetic energy of the waves into electrical energy, and making the stormy waves that create disasters serve human beings has been an ideal that people have dreamed of for many years.

The total power generation efficiency of wave energy devices is mostly relatively low, and the problem of improving the conversion efficiency of energy conversion structures at all levels of the device needs to be solved urgently.

Utility model content

In order to solve the above-mentioned technical problems in the prior art, the utility model provides a wave power generation device, which includes a support float and a power generation float. The support float is provided with a working platform, and a central hole and four a guide hole, a transmission shaft and four guide columns are respectively arranged on the power generation float, the transmission shaft passes through the center hole, the guide column passes through the guide hole, a coil is set on the transmission shaft, and the opposite on the working platform A surrounding wall is arranged on the inner side of the guide column, a magnet is arranged on the inner wall of the surrounding wall, and the coil moves up and down along the inside of the surrounding wall.

Further, a plurality of springs are provided between the working platform and the generating float, and the springs are sleeved on the guide columns.

The wave power generation device of the utility model has simple structure, convenient manufacture, high energy conversion efficiency, and greatly improved power generation efficiency compared with the existing wave power generation device.
