The “Haiming” wave power generation device uses the power of rising and falling waves to operate. It is a huge floating body resembling an oil tanker, measuring 80 meters long, 5 meters high, 12 meters wide and weighing approximately 500 tons. There are 20 “holes” at the bottom of the floater. These “holes” are actually air chambers. . As the waves continue to rise and fall, the air in the inner tube is constantly compressed and expanded, just like a bellows. Air rushes toward the blades of the air turbine and spins it quickly, driving the generator. to produce electricity.
Here, the up and down movement of waves plays the role of a general engine piston, which transforms the slow up and down movement of waves into a rapid rotational movement formed after the impact of the flow air at high speed. on the turbine. Thanks to the simple structure of theThe device, “Hai Ming” can convert 27% of wave energy into electrical energy.
The operating principle of the first wave power plant is exactly the same as that of the “Hamming”. A steel cylinder 12 meters high and weighing 40 tons is erected in a crack in the seaside cliff. When waves pass through the pipe When entering and exiting the cylinder, the water surface in the cylinder rises and falls, just like a powerful piston, causing air to be pushed out or drawn in at the top of the cylinder, thus pushing the turbine to spin and produce electricity. This plant produces 1.2 million kilowatt hours of electricity each year; if several cylinders along the coast are connected and working together, the waves can be used to produce more electricity.
The working principle of the second wave power plant is completely different from that ofthe second. She built a tapered tunnel to allow waves to enter from the mouth of the tunnel tens of meters wide, as the tunnel becomes narrower. and narrower, the incoming waves rise higher and higher, and finally flow into a small reservoir through the tunnel exit at a location 3 meters higher than sea level. A hydroelectric generator is installed at the exit of the tunnel reservoir. The result is similar to ordinary hydroelectric power. When the sea water from the reservoir returns to the ocean from a height of 3 meters through the outlet, it drives the hydroelectric generator to produce electricity. .
Norwegian wave power generation technology has been exported abroad. They first undertook a wave power generation project in Bali, Indonesia. The power plant has an installed capacity of 1,000 kilowatts. Then, a houlom power plant2,000 kilowatt generator was built in the Kingdom of Tonga and completed in 1990.
Not only can the power of the vertical up and down movement of waves be used to generate electricity, but the Left and right lateral movement of waves can also be used to convert wave energy into energy. mechanical rotation or rocking movement.
The British Salter has developed a wave energy production device in the shape of a “nodding duck”. It looks like a big dick. One end of the cam tip rotates around the camshaft, and the other end is a hollow cylinder. are inward and outward blades on the cylinder. The "nodding ducks" are connected by a string and float on the sea. When the waves come, they swing around the camshaft, and the cylinder blades also rotate back and forth, driving the water in the turbine and turning the turbogenerator. produce electricity.
The Swedes and the British have similar approaches and have developed a wave turbine energy production device. This power generation device consists of a series of wheels. When waves rush toward the wheel, seawater enters the wheel and turns the wheel blades. Finally, the shifting mechanism causes the generator to spin and produce electricity.
NewThere is also a type of wave power generation device called atoll-type wave power plant, which was developed and designed by the Americans. This type of power plant is a product that imitates a circular atoll on the sea. From the sea surface, only a circle with a diameter of 10 meters is visible, but the underwater artificial atoll is a huge thing. measures 76 meters, which is as big as a football fieldll. The circular wall of the artificial atoll is a deflector that guides waves towards the center of the atoll. As the waves rush toward the atoll-type powerhouse, the seawater will flow spirally in all directions along the atoll wall to the center of the atoll, where it will form a vortex and will turn the turbine to produce electricity.
