Problems solved by technology

In the disclosure of the invention patent Figure 5 and Figure 5 The shortcomings and technical bottlenecks in the technical solution of a are: windmills or sails can only achieve efficient power generation by reciprocating flight in low altitude through cables
If the windmill or sail is placed high in the air, the power generation efficiency is not high due to the large wind resistance generated by the circulating rope in the high air
In addition, due to the change of the flight trajectory of windmills, kites or sails in the air, the loop cable between the pulleys produces a line difference, and the line difference affects the power generation efficiency of the ground power generation device

Embodiment 1

[0056] Such as figure 1 and Figure 7 As shown, a kite power generation device includes a kite 7 and a first ground power generation platform 101, and the first ground power generation platform 101 is equipped with a first generator 103, a first winch 102 coaxially connected by a clutch 10, and a second windlass. Two hoists 111, the cables wound on the first hoist 102 are connected to the cables wound on the second hoist 111 through the first support 611 on the first ground power generation platform 101 and the second support 621 on the first ground power generation platform 101 Constitute the circulating cable 402 between the first hoisting machine 102 and the second hoisting machine 111; The kite 7 is fixedly connected by any point on the circulating cable 402 between the traction cable 6 and the first support 611 and the second support 621; The first hoist 102 and the second hoist 111 are respectively connected with the first torque motor 501 and the second torque motor 5...

Embodiment 2

[0069] Such as figure 2 and Figure 7 As shown, a kite power generation device also provides a movable second ground power generation platform 201 connected to the first ground power generation platform 101, and a coaxially connected first winch 102 is installed on the first ground power generation platform 101 and the first generator 103, the second hoisting machine 111 and the second generator 203 connected coaxially are installed on the second ground power generation platform 201, and the cables on the first hoisting machine 102 pass through the first ground power generation platform 101 The cable connection on the first support 611 of the second ground power generation platform 201 and the second support 621 constitutes the circulating cable 402 between the first winch 102 and the second winch 111; the first winch 102 and the second The winch 111 is respectively connected with the first torque motor 501 and the second torque motor 502 through gears or chains; the kite 7 ...

Embodiment 3

[0071] Such as image 3 ,Such as figure 2 As shown, the difference between this embodiment and Embodiment 2 is that in this embodiment, no support device is provided, that is to say, in this embodiment, deleting the support device does not affect the kite power generation device. power generation efficiency. In this embodiment, the second ground power generation platform 201 is towed by the second tractor 641 to move its position.

Abstract

The invention relates to a kite generator and an electricity generation control method thereof. The kite generator comprises a kite (7) and one or more ground electricity generation platforms. An electricity generator, a first winch and a second winch are installed on each ground electricity generation platform, wherein the first winch and the second winch are coaxially connected through a clutch, a cable wound on the first winch is connected with a cable wound on the second winch through a first support and a second support which are arranged on the electricity generation platform to form a circulation cable between the first winch and the second winch, the kite is fixedly connected with any point on the circulation cable through a traction cable, a first torque motor and a second torque motor are connected to the winches through gears or chains respectively, winding-up and paying-off of the winches are controlled through the torque motors, or a stepping motor or a servo motor, and the torque generated by the winches is connected with a gearbox through a power output shaft to drive the power generator to generate electricity. The kite generator is simple in structure, high in electricity generating efficiency, capable of guaranteeing continuous acting and low in cost, and therefore the wind energy utilization rate is increased effectively.

Description

technical field [0001] The invention belongs to the technical field of wind energy utilization, and relates to a high-altitude power generation device, in particular to a kite power generation device and a power generation control method thereof. Background technique [0002] In today's world, petroleum energy, coal energy, and natural gas energy are becoming more and more scarce. The development, utilization, and unrestricted consumption of a large amount of coal, oil, and other fuels have brought serious negative effects, such as inducing the greenhouse effect, acid rain, causing diseases, and agriculture. Serious problems such as production reduction have greatly polluted the environment on which human beings live. In addition, wars and natural disasters around the world have brought more and more difficulties to the collection and transportation of these energy sources. Energy security has become a priority for people all over the world. an important problem. Many probl...
