Background technique

Most of the current power plants are nuclear power generation, thermal power generation and hydropower generation, etc. However, although nuclear power generation has the advantages of low cost and high efficiency, its disadvantages are radiation leakage and the generation of nuclear waste.

It is extremely difficult to dispose of nuclear waste, and it will cause almost permanent pollution to the environment. Nuclear power generation will cause great harm to the environment and ecology; thermal power generation consumes a lot of fuel energy, and it has been proven that it will cause the greenhouse effect and will also cause serious damage to the environment. Produce air pollution and cause harm to the ecological environment; hydroelectric power generation will also cause harm to the ecological environment. Other methods, such as geothermal heat, are limited by availability and scale. Humans urgently need clean and sufficient energy to sustain civilization The development of solar energy and wind power is clean and inexhaustible, but the current usage method has insurmountable problems. The main disadvantage of solar power generation is that it requires a lot of ground space to set up, and it will be affected by terrain, latitude, season and Affected by the climate, solar power generation will be limited by the amount of sunlight, so there will be no power output in rainy days and nights, and seasonal changes will also make power output unstable; and there are also methods of using reflectors to collect the sun's heat to heat turbines.

In the present invention, a large-area solar power generation unit 11 and a wind power generation unit 12 array are placed high in the air, and a floating vehicle that can provide sufficient buoyancy is required. There are many ways to provide sufficient buoyancy, but at the same time, cost, manufacturing technology, For the installation method, it is better to use a lighter-than-air floating vehicle to avoid strong winds and maneuverability. The advantages of this type of vehicle are:

(1) The principle of buoyancy can be used to carry extremely heavy weights. Its technology has matured a hundred years ago and has been in commercial operation for a period of time. For example, airships before and after World War I have been used for commercial global travel and wars. Spaceships The average length is 220-250 meters, it can carry more than 15,000 kilograms, and it can fly to a height of 20,000 feet. With a length of 300 meters and a width of 200 meters, it can provide an area of 60,000 square meters, and every 10 square meters of silicon solar panels can provide about 1kW/h of power generation, so a 300mx200m silicon solar panel can provide about 6000kW The power generation per hour, if calculated with 6 hours of sunshine per day, the annual power generation is 6x6000x365=13140000 kWh of electricity, which is 0.39% of Linkou Power Plant (3.382 billion kWh per year). Estimate exceeds 0.5% of Linkou thermal power plant, as long as 200 floating devices of the present invention, the generating capacity just can be equal to the generating capacity of a medium-sized thermal power plant, if want to build a solar power plant equivalent in generating capacity and nuclear power plant, then about A solar panel with an area of 6,750 hectares is required, which is about fourteen times the current site area of the No. 4 Nuclear Power Plant. As long as there is an area of 700kmx700km and it is installed in a sunny place, it is enough to supply the current electricity required by the world. However, due to the present invention The power generation equipment floats in the air, so there is no land cost. Once it is completed, it will have a lifespan of about 30 years floating in the air, and it does not need any fuel, does not emit carbon, has no struggle, and is completely friendly to the environment.

(2) Using the principle of buoyancy, the height of the floating device can be controlled using the same principle as that of a submarine floating in water, which is convenient for driving to the expected location and appropriate height when leaving the factory or for maintenance, and then fixed on the ground with cables. When maintenance is required , you can put up the cable and drive back to the workshop for maintenance.

(3) It can avoid natural disasters. In bad weather, such as typhoons and heavy thunderstorms, it can take up the cable and drive away for refuge, and then return to the location, so the benefits and feasibility are beyond doubt.

Calculation example:

Design with power generation as the target: Taking the electricity of 13140000 degrees per year as an example (the size of a mini thermal power plant), solar panels with an area of 60,000 square meters are required, and the weight of solar panels per square meter is 12.5 kg, which must be carried 60000x12.5=750 tons of solar panels, the buoyancy of helium is about 1.05 kg per cubic meter, assuming that the total weight of the entire facility is 10000 tons (including 750 tons of solar panels), more than 10000000 cubic meters of helium is required , if the floating device is designed as n cylindrical buoyancy units with a length of 350 meters and a radius of 30 meters used in parallel, the volume of each floating unit is

30x30x3.14x350=989100 cubic meters, a total of n=10.11 buoyancy units connected in parallel are needed, taking n=11 can have enough buoyancy for reserve, and the occupied area is about 350x660 square meters. Divided into four equal parts, it will become four floating devices of 60x(175x330) square meters, or four floating devices of 60x(180x350) square meters (each floating device consists of three cylinders with a diameter of 60 meters and a length of 350 meters shaped buoyancy units in parallel), if you want to add a wind turbine for wind power generation, its buoyancy should also be sufficient (a small wind turbine weighs about 10–20 kg).

Technically speaking, take the Zeppelin spacecraft that began commercial operation in 1910 as an example: the technology at that time had reached a scale of 236.5 meters in length and 30.5 meters in diameter. The Hindenburg was even bigger, with a length of 245 meters and a diameter of 41 meters. , Therefore, today, 100 years later, technology is by no means a problem. Improvements in today's technology include: progress in materials, such as the use of carbon fiber instead of alloys, which can greatly reduce the weight of the vehicle and increase the strength of the structure, aerodynamics and The progress of fluid mechanics and the progress of automatic control, the larger the scale, the higher the benefit.

At an altitude of more than 3000 meters, the cloud cover decreases, the amount of sunshine and sunshine time increase, the wind is stable, and the wind speed is accelerated. It is suitable for solar and wind power generation. Solar power and wind power can be used during the day (when power consumption increases), and can be used at night. Wind power generation (when power consumption is reduced) can also be stored, easy to adjust, and can reach an ideal commercial scale.

The principle of solar power generation is to directly convert solar energy into direct current, which can be used for power storage, and no carbon dioxide will be generated after installation.

Centralized large-scale power generation will consume a large part of the power due to the problem of power transmission. Using decentralized regional power generation can reduce the loss, but the traditional power generation method used in decentralized power generation will make the pollution more serious , using the power generation equipment of the present invention can distribute power generation regionally without pollution, and can greatly reduce the loss of power transmission.

The above description is only illustrative of the present invention, rather than restrictive. Those of ordinary skill in the art understand that many modifications, changes or equivalents can be made without departing from the spirit and scope defined in the claims, but All will fall within the protection scope of the present invention.
