Power generation system with wind gathering power generation and ocean current power generation integrated into one

Abstract

The invention discloses a power generation system with wind gathering power generation and ocean current power generation integrated into one. The power generation system comprises a floating body, wherein a wind gathering power generation unit and an ocean current power generation unit are arranged on the floating body. The floating body is a ship-shaped cavity, and the ocean current power generation unit is placed in the floating body. The ocean current power generation unit includes an ocean current inlet and a wake current outlet, wherein the ocean current inlet and the wake current outlet are formed at two ends of the floating body, and an ocean current speeding-up pipeline is connected between the ocean current inlet and the wake current outlet. A conflux bucket is arranged at the position of the ocean current inlet. An air compressor, a power transmission and transformation device, a water turbine and a motor are arranged in a float above the ocean current speeding-up pipeline. A leading-out terminal of the motor is connected with the power transmission and transformation device by means of a cable. A water bucket of the water turbine extends into the ocean current speeding-up pipeline. A floating cabin is arranged in the floating body below the ocean current speeding-up pipeline. The wind gathering power generation unit includes a tower body, and a wind gathering head is arranged at the upper end of the tower body. A wind gathering pipeline is arranged in the tower body. A draught fan and a motor are arranged at the lower end of the wind gathering pipeline. A leading-out terminal of the motor is connected with the power transmission and transformation device by means of the cable. The power generation system with the wind gathering power generation and the ocean current power generation integrated into one has the advantages of being easy to construct and low in construction cost.

Description

technical field [0001] The invention relates to a power generating device. Specifically, it is a floating power generation system that can generate electricity using both hydropower and wind power. Background technique [0002] China's invention patent application No. 201110429077.7 discloses a wind power and hydropower integrated power generation system. The integrated wind and hydro power generation system includes a generator and a tower installed on the seabed and protruding out of the sea. The tower includes a column, the top of which is equipped with wind blades and a first transmission mechanism, and the section of the column in seawater is equipped with water wheel blades and a second transmission mechanism. Also mounted on the tower is an automatic gearbox and a differential with two input half shafts. The output shaft of the first transmission mechanism is connected with the first half shaft of the differential through the automatic transmission, the output shaf...

AI Technical Summary

Problems solved by technology

But there are the following problems: First, because this power generation system includes a tower with columns, during construction, it is necessary to drive piles on the seabed to install the tower and columns, and the construction is more difficult

The second is that the wind blades and water wheel blades of this power generation system are exposed above and below the water respectively, and there is no wind gathering mechanism and flow gathering mechanism, while the wind speed of the natural wind without gathering treatment is relatively slow, and the ocean current without gathering The power density is low. To increase the power generation capacity of a single power generation system, the wind blades and water wheel blades must be made very large.

However, if the wind blades and water wheel blades are large, not only the construction is difficult, the safety factor is low, and the construction cost will be greatly increased.

Therefore, the construction cost of this wind and hydropower integrated power generation system is relatively high
