Description

Offshore drone wind power platform

technical field

The invention belongs to the technical field of new offshore unmanned aerial vehicle wind power generation equipment, in particular to an offshore energy conversion platform that utilizes an unmanned aerial vehicle to collect wind power at high altitude to generate electricity.

Background technique

As a pollution-free, sustainable supply of green energy, wind power facilitates people's production and life, and its important role in the electric power society is self-evident. Offshore wind resources are abundant, and the amount of electricity generated by wind power on land is larger. Generally, the offshore wind speed 10 kilometers offshore is about 25% higher than that on land along the coast, which is less affected by the environment. Offshore wind power generation is less restricted by problems such as noise, bird impact, and electromagnetic wave interference. It does not occupy land land resources and does not involve land acquisition and other issues. Due to the unlimited energy contained in itself, offshore wind power generation has attracted more and more attention from all over the world.

China has abundant offshore wind energy resources. The water depth of the eastern coast is 2-15m. The contour of effective wind energy density greater than or equal to 200W/ ^m2 is parallel to the coastline. The effective wind energy density of coastal islands is above 300W/ ^m2 , and the annual wind speed is greater than or equal to The time equal to 3m/s is about 7000h～8000h, and the time greater than or equal to 6m/s is 4000h. The available wind energy resources are about three times that of land, reaching 700GW, and it is relatively close to the power load center.

A general wind power generating set includes a wind turbine, a generator, a variable speed drive and a corresponding controller, etc., which can be used to realize the energy conversion between wind energy and electric energy.

However, the power generated above is subject to the magnitude of the natural wind force, and the wind speed at sea varies greatly with height. Due to technical reasons, it is difficult for traditional offshore wind power generation equipment to reach a relatively high altitude to obtain wind power, so its power generation is low. Moreover, the construction of offshore wind power projects is complicated, and the construction period of supporting facilities is long, resulting in a sharp decline in the growth rate of offshore wind power installed capacity. In addition, due to technical reasons, the utilization of offshore wind energy only stays in the shallow sea of 30-50m. In order to greatly improve the utilization rate of offshore wind energy resources, offshore wind power generation equipment needs to be developed in deep sea.

Contents of the invention

The purpose of the present invention is to provide a new type of unmanned aerial vehicle power generation platform on the sea. By presetting the unmanned aerial vehicle on the platform at a designated position, it is usually placed on the sea surface. When the wind blows, the unmanned aerial vehicle will fly to an altitude of 300 meters spontaneously. Finally, the engine is turned off to capture the wind force to the maximum extent and convert the wind energy into electrical energy. It greatly reduces the construction complexity of traditional offshore wind power equipment. In addition, this platform can collect a large amount of wind energy at high altitudes to increase the power generation of the offshore wind power platform. In addition, the portability of this platform enables it to develop into the deep sea.

An offshore unmanned aerial vehicle wind power generation platform, including a box body, a left box cover, a right box cover, and a power supply, a servo mechanism, a generator and a cable retracting system located in the box body, and the opening and closing of the left box cover and the right box cover They are respectively controlled by their own servo motors to release the drone. The left box cover is slidingly connected with the left end of the box body opening through the left electric slide rail mechanism driven by the left servo motor, and the right box cover is connected by the right electric rail mechanism driven by the right servo motor. The slide rail mechanism is slidingly connected to the right end of the box; the cable retracting system is connected to the UAV through a traction rope. When the UAV moves, it pulls and drives the generator through the traction rope. Once the traction rope is rolled out of the predetermined tether length, the cable retraction system rewinds the pull rope.

The present invention has the following advantages due to the adoption of the above technical scheme:

1. The platform is based on the high-altitude passive flight of drones, which can collect huge high-altitude wind resources on the sea surface and convert them into electrical energy. Compared with traditional offshore wind power generation equipment, its efficiency and power have been greatly improved.

2. The platform has a simple structure and can be stored in a box. The whole system is very convenient to transport. A large number of such platforms can be deployed on the sea surface. One of the platforms can generate 100KW of electricity, and hundreds of offshore comprehensive energy conversion platforms can completely provide the electricity for a small factory. At the same time, it serves as a small energy supply platform floating on the sea to provide energy supply for ships, fishing grounds or military activities.

3. The platform does not require offshore foundations or underwater operations, and does not require on-site disassembly and installation. The entire system is very convenient to install. Therefore, those areas (such as deep sea) where traditional offshore power generation platforms are difficult to place, can use this platform to provide uninterrupted power for these areas.

Detailed ways

The invention utilizes the abundant wind resources at high altitudes on the sea, innovatively uses a rope to tie a specially configured drone to an offshore platform, and the kite-like turbine can capture wind energy at an altitude of 300 meters to 400 meters above sea level. Much less affected than "traditional" structures.

As shown in Figures 1 and 2, the new offshore UAV wind power generation system provided by the present invention includes: a power generation platform 3 preset on the sea surface; the UAV 1 transmits wind power to the power generation platform through a traction rope 2 at high altitude 3 for electrical energy conversion. power supply, servomechanism, generator and cable retraction system,

The power generation platform includes a box body, a left box cover 4, a right box cover 5, a power supply 11 located in the box body, a servo mechanism, a generator 9 and a cable retracting system, and the left box cover 4 and the right box cover 5 are respectively controlled by a servo motor , the left box cover is slidingly connected with the left end of the opening of the box body through the left electric slide rail mechanism driven by the left servo motor, and the right box cover is slidingly connected with the right end of the box body through the right electric slide rail mechanism driven by the right servo motor. When the wind blows, the lid opens to release the drone.

Figure 2 shows the internal structure of the platform. The UAV 1 is connected with the traction rope winch 6 by means of the traction rope. After starting, the UAV 1 flies vertically along the plane perpendicular to the traction rope. The trajectory is superimposed on the release motion, and the flight trajectory Can be arc-shaped or 8-shaped. The magnitude of the arc and its horizontal or vertical orientation are selected according to the wind direction, so that it can transmit the traction generated by the UAV 1 to the generator for power generation through the traction rope, during which the cable retractable system (refer to: Ren Xuefeng’s one for The cable retractable device of the retractable cabin of the tethered UAV: China, 201620660491.7[P]. The traction rope pulls and drives the generator. Once the traction rope is rolled out of the predetermined tether length, the UAV 1 automatically descends to the ground, and the cable retracting system 8 makes the traction rope rewind. Then, UAV 1 drives the traction rope to rise by wind force and repeats the process. Going back and forth like this generates electricity.

The power used in the starting process of the UAV is provided by the power supply 11, and the wind energy collected by the high-altitude UAV is converted into electrical energy by the generator 9, and the converted electrical energy is output by the digital-to-analog converter 10 for external use.

When the wind blows, the UAV’s bolt-wings are automatically activated from the platform site, and the lift is provided and controlled by the small propeller. After flying to an altitude of 300 meters, the engine is automatically turned off. With the high-altitude strong wind, it will be passively controlled in the shape of a number 8. In flight, a generator on the platform converts the mechanical energy generated by the movement into electrical energy. Such a power generation mode can capture wind power to the maximum extent through the flexible change of position and angle of the UAV in the air.
