Abstract

The wind driven generator is a new wind driven generator in the field of wind power generation and a design and manufacturing technology. Firstly, wind driven generators in the world directly generate electricity on the top of an iron tower, and the wind driven generator of the invention firstly uses a special wind wheel to rotate a crankshaft to drive a single-cylinder air compressor to generate compressed air and then uses a pneumatic device to drive a generator to generate electricity. Secondly, the existing three-blade windmill loses too much wind and energy, and the self-protection is realized in case of strong wind, and the automatic power-off is realized to prevent the power generation; the wind driven generator of the invention uses the wind wheel with the booster ring to obtain more wind energy. The finely adjusted wind wheel can rotate at high speed to generate compressed air. The improved pneumatic motor drives a generator to generate electricity. And thirdly, the compressed air can also be derived from electricity generated by various power plants at night and electricity generated by solar energy in the daytime (including electricity generated by the generator at night), and is immediately changed into compressed air by the electric air compressor. After the compressed air is input into the compressed air network, the generator is used for generating electricity in the day next day.

Description

Half-moon-shaped wind wheel wind power compressed air turbine generator and design and manufacturing technology thereof

The technical field is as follows:

a half-moon-shaped wind wheel wind power compressed air turbine generator and a design and manufacturing technology thereof are different from the existing wind power generator with a three-blade windmill driving a speed change gear set to directly generate power and the power generation technology of the design and manufacturing technology. The name source of the half-moon-shaped wind wheel wind power compressed air turbine generator is as follows: the three-blade windmill is changed into a wind wheel, and a pressurizing cover is additionally arranged on the outer edge of the wind wheel. The wind wheel looks like a half moon, so the name is given { half moon }. Fig. 2 is a block schematic thereof: (1) the three-blade windmill is changed into a front half moon shape, a rear half moon shape, a wind wheel with multiple blades, connected outer edges and wind shielding and pressure increasing rings. Two wind wheels are respectively strung on the front part and the middle part of the same linear shaft and fastened; (reliable fastening, for screw threading is necessary). The other end of the horizontal shaft is additionally provided with a crankshaft, and the crankshaft is provided with a cylinder piston connecting rod of single cylinder compressed air. (like the pumping unit of the petroleum field, become to use for compressing the air now from former Leishui pumping oil). When the high-large (the diameter can reach hundreds of meters) double wind wheels rotate synchronously, air is filtered by the large-capacity air filter, then the air is sucked into the inflator by the piston, and the inflator can continuously input high-pressure compressed air with the pressure of 60 kilograms into a plurality of high-pressure containers connected in parallel through high-pressure air pipes. (the oxygen steel cylinders are connected in parallel, the factory qualification testing pressure of the oxygen steel cylinders is 365 kg, the normal oxygen charging pressure is 150 kg; a long-year stainless coating is formed in the cylinders after special process treatment, the oxygen steel cylinders are connected in parallel for a long time, the year picking period is very long, and the high-pressure container can also be made into a large-diameter and parallel-connected ball body by using a thick steel plate). The pipeline in the process is provided with a plurality of air one-way check valves, a two-way differential pressure check valve, a multi-point pressure limiting safety relief valve, a plurality of air filters and the like. (2) Clean high-pressure air flows into the air outlet main pipe of the pressure container after being buffered by the air pressure of the high-pressure container group. The manifold is provided with an integrated, sufficient oxygen pressure reducer. After more than two pressure reducers are connected in series, all the oxygen pressure reducing meters connected in series are regulated to constant pressure. The pressure of the collected pressure reducer downstream main pipe is slightly larger than the steam pressure and the steam flow of a steam turbine generator of a power plant. (35 kg pressure, gas flow equal). (3) The double-channel double-series gas circuit switch and the standby non-stop gas circuit maintenance pipeline are installed on the main pipe leading to the generator airflow in parallel, and the small generator set moving by the motor home can selectively start and stop power by opening and closing the gas passage, so that compressed air is saved. The wind wheel generator set for the independent residence creates the possibility of household power generation, power utilization and metering of sold power or compressing air to a public power grid and an air grid. The compressed air is connected with an air network, more importantly, the compressed air is convenient for the whole people to participate in the compressed air, so that the problem of lack of clean energy in China is fundamentally solved, and the compressed air can be used for herdsmen, shipmen and tourism.

II, secondly: background

At present, the wind power generation in China is almost the main of national investment; the financial resources of enterprises and the national subsidies are supplemented: individual investments in building independent wind power plants are almost none. The reason is as follows: (1) large investment, long recovery period, low income, poor power generation efficiency, difficult integration into national power grid, expensive electricity storage battery and short service cycle. The existing wind power generation is that the windmill directly generates electricity, sometimes, the voltage is unstable, the national power grid is lack of electricity, and the wind power generation is free of wind; the national power grid does not need electricity, and the electricity generated by the national power grid cannot be sold. Grid connection sometimes causes the national grid voltage to fluctuate. More importantly, the electricity cannot be sold because the transmission current of the high-voltage line transmitted to a remote place has an upper limit. A high-voltage clamp tower is erected independently in a personal wind power plant and is conveyed to a remote place, and the high-voltage clamp tower is difficult to transport in a square surface. (2) In order to buffer the problem of wind power and electricity, wind power generation and solar power generation are combined and networked. (the solar power generation voltage is unstable, and the sun is charged and the rain is not charged). The method solves part of problems by combining the two methods. But the problem of long-distance wind energy output is not fundamentally solved. It is feasible to send wind energy to a distant place by using a high-pressure air pipe. (3) Some wind power plants directly send the generated electricity to a hydroelectric power station, and send the generated water back to a reservoir by using wind power to convert electric energy into potential energy (water energy)) for storage, but hydropower stations with sufficient water sources do not work. Therefore, in places far away from the hydroelectric power plant or where no hydroelectric power plant exists at all, the wind power plant generates more electricity (seasonal power generation), and the electricity generated by solar energy can be stored or abandoned only by using a battery. The national grid has limited transmission capacity and cannot be sold. (4) In northwest China, some enterprises generate power independently and develop rapidly. They have solved the enterprises' guaranteed electricity usage by combining three sets of methods: they developed and built their own wind power plants; solar power generation equipment is also built; in addition, a self-contained diesel generator set is also built to be used as standby supplementary emergency electricity; they are also not completely disconnected from the national grid, if possible, but use little electricity. The electricity is sold little, (5) the existing wind power generation is that each windmill drives a group of gear speed change groups and a generator to generate electricity, the investment is large, the cost is too expensive, the maintenance cost is high, and the electricity cannot be generated when the wind is large (the wind stops automatically); the wind is small and the power generation can not be realized. (the windmill blades are thin and long and have small wind area). The maintenance cost is large. The east China sea has a wind driven generator which is the largest in China, the diameter of a three-blade windmill of the wind driven generator is 123 meters, the offshore installation cost is 100 ten thousand yuan each day, the manufacturing cost of the generator is not published, the generated electricity can be sold, and the investment cost can be recovered in 20 years. The usual maintenance costs are not included. Is too expensive, so that the individual investment in wind power plants is now small.

The wind energy generated every year all over the world is three times of the total fossil energy consumed every year by human beings (nuclear energy is not included due to the problem of nuclear waste disposal), and the fossil energy sources in China: the import is the main, and the demand is increasing. If there is a war, the supply is blocked. China lacks petroleum and natural gas; but never lack the compressed air produced by a tall wind wheel! The compressed air is used for power generation, and the method has great prospect: not asking for people at ordinary times and being afraid of during war! The sea road is not ventilated, and China has electricity when being windy! Nature sends the taifeng north to south China every year; in the south of the northwest wind in the north, wind blows stones and vehicles fall down from the roadside, which is the energy source for Chinese people in the past day! Which countries in the world give this much typhoon energy in the old days? But also has such good three-level gradient altitude topography. On the border defense line of a high mountain sentry, a sentry needs to change a new national flag every seven days because the original national flag is blown through by strong wind. China has huge wind energy. Only three-blade windmill is changed into high-efficiency wind wheel to improve the utilization rate of wind energy, and huge wind wheel is arranged on the top of the mountain to produce compressed air, so that China does not lack clean energy.

Third, the invention content name:

(1) It thoroughly solves the fatal problem of wind scarcity of the wind-driven generator. The wind power generation tower can also generate electricity in typhoon. The wind is not too large, and the wind-driven self-protection automatic stop device is self-protection and automatic stop. The larger the wind, the better! The more compressed air produced!

(2) Wind power generators on the world now, windmills like three dragonfly wings, thin and long. Wind energy is lost too much. The wind driven generator of the invention is characterized in that the windmill is made into a wind wheel, so that the windward area can be greatly increased, and the energy which is several times more than that of a three-blade windmill is obtained. The wind wheel No. 6 of the figure 3 rotates fastest, and the wind wheel No. 1 rotates slowest. The No. 1 windmill is the current situation of the existing wind driven generator. )

(3) The existing wind driven generator is characterized in that a three-blade windmill directly drives a gear speed change mechanism and simultaneously directly drives a generator to generate electricity, and the existing wind driven generator has multiple equipment expenses of electricity storage, (influence of waste and old batteries on the environment), voltage transformation, and the like. The maintenance work in the high altitude on ordinary days, staff climb up and down, receive weather effect sometimes can not go on yet. The wind driven generator designed by the inventor is not used for directly generating electricity, but the wind wheel drives the crankshaft to generate compressed air, the compressed air is used for driving the steam turbine to generate electricity, and the rotating speed of the crankshaft is not afraid of typhoon. The more the typhoon gets the more the compressed air! The more electricity is generated, and the more the power supply is, the more the national power grid is popular. The workload of high-altitude operation is greatly reduced. The high altitude maintenance is interfered by various factors and is unsafe.

(4) In order to improve the power generation efficiency, the existing wind power station can be built only in a place with large wind on the second foundation of China, at the seaside and in the world, and the popularization of the existing wind power station is difficult. My wind generator does not have the above problems.

(5) The existing wind driven generator is characterized in that three-blade windmills firstly generate electricity and then the electricity generated by each windmill is connected to the grid; the wind driven generator firstly generates compressed air respectively, then the compressed air is connected in parallel with a high-pressure container, the air pressure is buffered, and then the wind driven generator is used for generating power by using a steam turbine generator of a large or medium thermal power plant. The high-pressure air pipes can be connected with a network, and the wartime machine room can be arranged underground. If the solar energy is converted into compressed air by the electric air compressor and is connected to the grid, and if the electricity generated by any other power plant (including wind power and all power plants capable of generating electricity) at night is immediately converted into the compressed air by the electric air compressor and is connected to the grid, the electricity price is reduced greatly. People are cheering. (the high pressure gas network is also a capacity supplement to the vessel.)

(6) The wind wheel, the wind wheel shaft, the crankshaft, the inflator connecting rod, the inflator (purchased from an oxygen steel cylinder) are not products of high branches, and the wind wheel, the wind wheel shaft, the crankshaft, the inflator connecting rod and the inflator are convenient to manufacture and maintain, have low cost and are beneficial to producing the household wind driven generator. The oxygen steel cylinder is purchased, and is firstly tested and then used. And the clip tower is low in cost because the generator is not arranged at the top of the tower.

Fourthly, the advantages of the half-moon-shaped wind driven generator:

(1) the half-moon-shaped wind wheel generator is characterized in that a three-blade windmill is changed into a wind wheel, and a wind collecting cover is additionally arranged on the periphery of the wind wheel, so that wind wheels rotate under the condition that wind pressure is larger than that of the blades of the three-blade windmill in the same environment, natural wind power is not artificially increased, and the rotating speed of the half-moon-shaped wind wheel is increased on the original basis, so that the generating efficiency is improved. The small wind can also generate electricity, which is better than three-blade windmill.

(2) The half-moon-shaped wind wheel is like two or more umbrellas (universal joint connecting shafts are supported by bent frames) which are spread, laid and strung together horizontally, wind blows from the umbrella handle, the openings of the wind wheel blades are arranged at the top of 3 parts of the umbrella cover 4, and the obtained wind pressure is larger than that outside the umbrella cover. (the tension is large, the pressure on the blade is large, the rotation is fast, the pressure of the three-blade windmill is much smaller, the mantle of the rotation is much smaller, the energy is saved, and the like) (the tension is large, the wind pressure on the blade is large, and the rotation speed is also fast) and the energy is reduced in the figure 3

(3) The problem of static balance and dynamic balance of the half-moon-shaped wind wheel is solved, and the half-moon-shaped wind wheel works carefully, and like a ferris wheel arranged in a park, needs to be enabled to rotate firmly and very balancedly and quickly. (usually, the double thin thread screw caps are used for fine alignment to ensure that no vibration exists when strong wind runs at high speed).

(4) Although the diameter of the half-moon-shaped wind wheel is large, the structure is easy, and zero Gao wind wheels with the same diameter can be interchanged, so that the cost is reduced.

(5) The driving generator can be driven by an air motor, a rack gear, a spring box and the like

After rough adjustment, the alloy is stringed on a horizontal uranium with the height of five meters (such as a rear wheel of a bicycle) and is fastened with a shaft, and the fine roundness is adjusted to a millimeter level.

5. The air filter is provided with a material for conveniently replacing the large-faced Zhi filter material, and the material is combined with the wind wheel bracket. The maintenance period is prolonged, and the maintenance period is prolonged,

6. the high pressure air flow of the inflator passes through the one-way check valve of the high pressure air pipe, then passes through the left path of the tee joint to the middle path, and is sent into the high pressure container, the right path of the tee joint is connected with the left path of the upper tee joint and the lower tee joint through the high pressure pipe, and the middle path of the second tee joint is connected with the second container through the high pressure pipe. The right path of the second tee joint is connected with the left path of the third tee joint, the middle path is connected with the gas container, the right path is connected with the left path of the next tee joint, the middle path is connected with the third container, and the right path is connected with the left path of the next tee joint. Thus, a parallel gas containing group is formed. The left and right passages need to be connected by a large flow pipe, and the diameter of the middle passage can be smaller. (reducing tee joint can be used).

7. The right high-pressure pipe of the last tee joint is connected with the middle tee joint in the middle of the main air inlet pipe of the air outlet meter row, and the diameters of the left and right pipes are thicker. The series of decompression tables is reserved with sufficient standby flow for changing tables. (normal power generation is not affected).

8. The constant compressed air with stable pressure enters the modified pneumatic motor (or gas turbine) to drive the generator to generate stable and constant power current.

The above is a small household generator.

Claims

1. It is characterized in that: the wind wheel with the increased wind pressure cover is used for replacing the existing 3-blade windmill, and more wind power generators with larger wind energy can be obtained under the premise of the same environment and the same wind power.

2. The half-moon-shaped wind driven generator (for short) is different from the existing wind driven generator that the windmill drives the gear to directly generate electricity, but uses the held crankshaft to drive the single-cylinder long-stroke air compressor to produce compressed air, and uses the compressed air to drive the pneumatic motor (or the pneumatic turbine) to drive the generator to generate electricity after the compressed air is buffered in parallel by the large-capacity high-pressure container. The voltage is stable.

3. The half-moon-shaped wind driven generator does not use the processes of battery electricity storage, voltage transformation and the like, but uses a pressure pipeline and a container to store compressed air, and as long as air does not leak and energy is not lost! Ten years air pressure is not changed! The energy storage cost is also low, and the battery is not practical. More importantly: the high-pressure air pipe can be deeply piled underground, and the wind energy is concentrated and then sent to a far place to be used for generating electricity by a large-sized or medium-sized generator. In case of war, the generator can enter the underground to generate electricity. Only the wind wheel is visible.

4. Half moon shape aerogenerator is different from current windmill generator: each windmill of the existing generators drives one generator. The maintenance and the repair are all at high altitude, the equipment cost is high, the investment is large, and whether the weather is allowed or not is judged through the maintenance; the crank shaft of the wind wheel of the half-moon-shaped wind driven generator drives the piston connecting rod, so that the half-moon-shaped wind driven generator is simple in structure, resistant to high-speed rotation, lighter in weight than the generator, less in fault, low in cost, convenient to replace and long in service life, and most importantly, the generator does not need to be stopped when the wind is strong, and the compressed air is more when the wind is strong. The generator is on the ground or underground, the maintenance is convenient, the operation is safe, and the cost of the iron tower is relatively low. If the fixed long-row bracket is designed to form a string wheel in the unmanned area, the energy is larger.

5. The compressed air of the half-moon-shaped wind driven generator can also come from a solar power station, so that the solar power station does not need to store electricity, but the electricity generated by the electricity is converted into compressed air by using an electric air compressor, and is connected to the grid! Thus, the difficulties of electricity storage, transformation, power transmission and the like are solved; in addition, the power generated by the hydropower station with sufficient water source at night can be immediately converted into compressed air for grid connection, and the energy is transmitted to a remote place for power generation. In summary: china can buy natural gas from thousands of miles, and worry about price rise and supply interruption after money is paid. And the networking of compressed air collection in a wide area of China is feasible. No need to ask for people at ordinary times, and continuous supply during wartime! Each individual, who is conditionally collecting compressed air, participates in it. Only play the vertical wind wheel for carrying.

6. The power of the wind power compressed air turbine generator with the half-moon-shaped wind wheels is derived from compressed air, and a lot of ways are available for obtaining the compressed air, and the compressed air energy is little in storage, transportation and loss, so that the technical wood method based on the above change improvement is a protection example.
