Floating type wind energy receiving device

Abstract

The invention discloses a floating type wind energy receiving device, comprising a spiral body and hauling cables, wherein the spiral body is a single spiral air bag, the diameter of the spiral body is gradually reduced to be in an inverted cone shape from top to bottom, and the air bag is filled with light gas. The hauling cables which are at least three are arranged along the bus direction of the spiral body and are connected with the surface of the spiral body, and the lower end of each hauling cable is connected with a driving device for driving an electric generator. Compared with the prior art, the floating type wind energy receiving device has the advantages of simple structure, convenience for operation, low cost, light weight and high using safety and can effectively utilize high-altitude wind energy.

Description

technical field [0001] The present invention relates to a wind energy generating equipment, in particular to a floating wind energy receiving device which utilizes high air flow to generate power. Background technique [0002] The wind energy receiving device is a device that converts wind energy into rotational mechanical energy. At present, the commonly used wind energy receiving device is the wind blade, which is installed on the top of the wind tower to drive the generator to generate electricity. Limited by the height of the wind tower, this kind of wind energy receiving device can only receive and utilize wind energy near the ground, and because the wind speed on the ground is low and the energy is small, if you want to increase the power of wind power generation, you can only use large-sized wind power as much as possible. The blades increase the wind-receiving area, which also brings about a sharp increase in cost, and the size of the wind blades cannot be increased...

AI Technical Summary

Problems solved by technology

[0006] 1. A complex steering control system is required. This technology requires a high degree of automatic computer control, and there must be accurate wind measuring devices around. Since the kite is constantly changing, there is no stable state (not only can it not work in a stable state, but the kite will fall. Down), it is necessary to continuously detect and calculate the force state of the kite, and adjust the attitude of the kite so that the kite on one side is in a state of full wind resistance, which pulls the power generation equipment to run, and the kite on the other side is in a state of low wind resistance to reduce the resistance moment. The device can always rotate in one direction to generate electricity, so a complex calculation control system is required

At the same time, the stability of the technology is poor

[0007] 2. As mentioned above, the kite needs to be constantly switched between full resistance and low resistance to drive the power generation equipment to rotate and generate electricity. However, as the kite is retracted and released, there will be continuous pulsating shocks, resulting in pulsating electricity. Increased investment in power transmission and transformation systems, as well as the complexity of the work process

[0008] 3. The energy density of wind power is already very low, and power is consumed to fly the kite, which further reduces the utilization rate of wind energy

[0009] 4. Poor aerodynamics, almost entirely drag type, low efficiency

[0010] 5. Complicated operation and poor practicability: the thousand-meter-long rope pulls a kite the size of a football field, and the operation of flying into the air is complicated

These power generating devices also have some common shortcomings: 1, because the wind energy receiving device and the generating mechanism are all floating in the air, the structure of the wind power generating device is complicated and the weight is heavy, which restricts the further improvement of its power; 2, the volume 1. The power generation devices with relatively large weight are all set in the air. Once they crash, they will pose a threat to the safety of the ground, and the safety is poor; The wind energy received by the wind in some directions is low, and the variability of high-air flow restricts its effective use of wind energy. 4. It is necessary to install additional floating devices in order to lift the power generation device into the sky, which increases the manufacturing cost.
