Umbrella type wind energy conversion device and system

Abstract

The invention discloses an umbrella type wind energy conversion device and an umbrella type wind energy conversion system. The device comprises a rail rope, and a lower control box, a lower baffle block and an upper baffle block which are fixedly connected to the rail rope sequentially from top to bottom, wherein the lower control box is connected with a sliding barrel through at least one umbrella control rope; a plurality of work application umbrellas are connected between an umbrella edge and the sliding barrel; the upper control box is in engagement transmission with a chain; when the lower control box reaches an operation lower limit position relative to the ground, a first prompting signal is transmitted to make the lower control box retract the umbrella control rope, so that the work application umbrellas are unfolded under the action of wind power; and when the lower control box reaches an operation upper limit position relative to the ground, a second prompting signal is transmitted to make the lower control box release the umbrella control rope, and the upper control box moves downwards along the chain to drive the tops of the work application umbrellas to move downwardsso as to fold the work application umbrellas. By the device and the system, the work application umbrellas can be more stably unfolded and folded in the air, the phenomenon of twisting caused by redundant rope tools during unfolding and folding of the work application umbrellas can be effectively prevented, and high-power wind energy can be stably converted.

Description

technical field [0001] The invention relates to a wind energy conversion control system, in particular to an umbrella-shaped wind energy conversion device and system for converting wind energy into power in wind energy applications. Background technique [0002] The wind energy stored in the sky is more than 100 times the total energy demand of human society. The effective wind energy density in the air above 5000 meters in most areas of China is above 1000 watts / square meter. All over the world, most of them only stay in the field of low-altitude wind energy research, and the utilization of high-altitude wind energy will become a promising technical field on the road to new energy development. [0003] The utilization of high-altitude wind energy is to convert wind energy at high altitude, convert wind energy into mechanical energy, and finally convert mechanical energy into electrical energy or other forms of energy. [0004] At present, the mainstream of high-altitude w...

Problems solved by technology

However, in the kite-type high-altitude wind energy conversion control system commonly used at present, the kite is both a balance body and a work body, that is, a unified control method of the balance body and work body is usually used at present, which is difficult to control and difficult to achieve stable high-power energy The supply of high-altitude wind energy control technology has not been well resolved

In addition, the current high-altitude kite-type energy conversion control technology converts wind energy into electrical energy or other forms of energy when the work body rises, and the energy supply stops when the work body descends, so it is difficult to meet the continuous and stable energy supply

In order to realize the high-power energy conversion of high-altitude wind energy, multiple work bodies are required to do work to realize the accumulation of energy conversion. Therefore, the interaction between the ropes of multiple work bodies is prone to entanglement, resulting in the termination of the work process.

[0005] The high-altitude wind energy conversion control technology is currently the bottleneck of high-altitude wind energy providing stable and high-power energy, and plays a key and important role. However, the current common high-altitude wind energy conversion control system is difficult to achieve high-altitude partial control stability and high-power energy conversion. , it is difficult to meet the needs of human production and life
