Description

A wind powered air compressor generator

Technical field

The invention relates to the technical field of wind power generation, and in particular to a wind power and air pressure power generation device used at sea.

Background technique

At present, the largest wind turbine wings in the world are more than 100 meters long. When operating in the thousand-meter-deep sea where hurricanes are rampant to generate electricity, a strong base must be built to withstand the impact of hurricanes. Moreover, wind turbines with wings of more than 100 meters are extremely vulnerable to the impact of hurricanes. It is easy to lose control and be damaged. The characteristics of wind include large fluctuations in wind intensity and discontinuity, making the power output from wind turbines extremely unstable. It is difficult to build a strong base in the thousand-meter-deep sea where hurricanes are rampant. It also damages the marine environment and the output power is unstable and discontinuous, which seriously restricts human development of deep-sea wind power.

A wind turbine with a wing length of more than 100 meters can drive a huge power generator, which also increases the investment and construction difficulty of a solid base. Some people also use wind-powered air compressors to convert compressed air. For example, the Chinese patent application number is CN201110217118.6, the application publication number is CN102913393A, the application date is 2017.07.12, the application publication date is 2011.07.31, and the application publication date is 2013.02. The 06 invention application discloses a compressed air turbine wind generator, which is composed of a natural wind air compressor, a compressed air storage tank, a compressed air duct and a turbine generator. The natural wind air compressor drives the compressor through the rotation of the wind blades. The compressed air is sent to the compressed air storage tank, and then drives the turbine blades of the turbine generator through the compressed air duct to make the generator generate electricity. Since the above invention does not require the blades to directly drive the generator, and the rotating parts of the blades are not attached with structures such as wires and sliding brushes, it has the advantages of safe working conditions, stable power generation, and the turbine is not easily damaged, even if there is no natural wind for the time being. It can also generate electricity continuously. However, for wind power generation, there is still a need for CCB's corresponding construction facilities as a foundation.

In view of this, it is necessary to propose a power generation device that generates stable power, can be moved and used on the sea surface, and does not require the construction of large infrastructure.

Best Mode of Carrying Out the Invention

The specific embodiments of the present invention will be further described below to make the technical solutions and beneficial effects of the present invention clearer and clearer. The embodiments described below are illustrative and intended to explain the present invention, but should not be construed as limiting the present invention.

Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions.

Example 1.

As shown in Figure 1, the wind-driven air compressor generator is a mobile generator that does not require the construction of a basic machine base, has wind power generation, and has continuous and stable power output. The wind-driven air compressor generator is mainly composed of a wind-pressed compressed air device and a gas storage device. The tank 13 and the compressed air power generation device 11 are composed of three parts. The wind pressure compressed air device includes a compressor and a base 1 that supports the air compressor. The compressor consists of a compressor casing 2, a windward wing 5 arranged at the upper end, and a windward wing 5 arranged at the upper end of the compressor. The transmission shaft 4 in the middle of the housing 2 and the rear end of the transmission shaft 4 are provided with a wind power fan 7. The middle end of the transmission shaft 4 is provided with a transmission wheel (inertia wheel). The transmission wheel can be a pulley or a gear. The front end shell of the transmission shaft 4 The body is provided with a compressed air fan 3, and the housing is an inverted cone structure airway. The rear end of the airway is connected to one end of the air storage tank 13 through a pipeline, and the other end of the air storage tank 13 is connected to the compressed air power generation device 11 through a pipeline. One-way valve 12 and two one-way valve are provided respectively; the machine base 1 is set on a platform composed of a pressurized water tank 18 and a column 19 provided below the pressurized water tank 18, and the column 19 is connected to the seabed; the compressed air power generation device 11 It is composed of a reciprocating cylinder 9 connected to the pipeline of the gas storage tank 13, magnets 10 connecting the two ends of the reciprocating cylinder 9, and a power generation coil 8 in which the magnet 10 enters and exits.

Here's how it works.

When the wind comes, the windward wing 5 automatically points to the direction of the coming wind. The wind drives the wind power fan 7 to rotate. The wind power fan 7 drives the compressor fan 3 through the transmission shaft 4 to suck in air and enter the compressor airway to compress the air. The compressed air passes through the one-way valve. 12 enters the gas tank 13 for storage. The gas tank 13 stores a certain amount of compressed air and then opens the pressure limiting valve 14. The compressed air enters the reciprocating cylinder 9 through the pressure limiting valve 14 and pushes the piston of the reciprocating cylinder 9 to reciprocate. The magnet 10 on the power generator performs a reciprocating pull-out action in the power generation coil 8, causing the magnetic flux in the power generation coil 8 to change to generate electromotive force to generate electricity. The water pressure chamber 18 is filled with sea water, and the weight of the pressure water chamber 18 is used to press the column 19 so that the column 19 is not blown down by the wind when standing in the sea.

Example 2.

As shown in Figure 2 below: In order to ensure the continuous and stable power generation of the compressed air power generation device 11, a low-pressure pressure limiting valve 20 and a pneumatic control valve 21 are added to the compressed air path. The air storage tank 13 stores a certain amount of compressed air through the pressure limiting valve 14. Compressed air is provided to the compressed air power generation device 11 so that the compressed air working range of the compressed air power generation device 11 is between P1-P2 of the pressure limiting valve 14 and the low pressure pressure limiting valve 20 to ensure that the compressed air power generation device 11 can achieve continuous power generation.

Example three.

This embodiment is aimed at a deep-sea wind-driven air compressor generator, as shown in Figure 3. The difference from Embodiment 1 is that the air storage tank is used as a support platform, that is, the machine base 1 is set on the air storage tank. The tight pulley or gear is drivingly connected to the propeller drive shaft 16 through a belt 15 or a chain. A propeller 17 is provided at the end of the drive shaft. The wind air compressor generator floats on the deep sea surface with the air storage tank 13 as a platform. When the wind comes, the wind power fan 7 The pulley 6, the belt 15 and the propeller drive shaft 16 drive the propeller 17 to rotate and drive the sea water, driving the wind air compressor generator to sail against the wind to offset the thrust of the wind on the wind air compressor generator. The middle end of the drive shaft 4 is provided with a transmission Wheel (inertia wheel) 6.

The present invention has the following advantages over traditional power generation methods.

1. The present invention uses wind power as power, and the wind power fan 7 drives the air fan 3 to compress the compressed air. It is not limited to the method of driving the screw to compress the compressed air or the pneumatic motor to compress the compressed air.

[2. The present invention uses the compressed air power generation device 11 as the power generation method.

3. Fill the pressure water tank 18 with seawater, and use the weight of the pressure water tank 18 to press the column 19 so that the column 19 will not be blown down by the wind when standing in the sea. It is not limited to storing heavy objects in the pressurized water tank 18.

4. The wind-driven air compressor generator uses the gas storage tank 13 as a platform to float on the deep sea surface, and has a simpler structure.

5. The wind drives the wind power fan 7 to drive the propeller 17 to rotate and drive seawater through the pulley 6, the belt 15, and the propeller drive shaft 16 to offset the thrust of the wind on the wind air compressor generator. The transmission method to offset the thrust of the wind force on the wind air compressor generator is not limited to belt transmission and gear transmission.

6. The working principle of the wind-powered air compressor generator is to use wind power as power to suppress compressed air, use the produced compressed air to generate electricity, and use wind power as power to drive the propeller 17 forward against the wind to offset the thrust of the wind power on the wind-powered air compressor generator.

7. The working principle of the wind air compressor generator is to use wind as power to suppress compressed air, use the produced compressed air to generate electricity, and use the gravity of the pressurized water tank 18 to offset the thrust of the wind on the wind air compressor generator and the force of the waves on the wind. The impact of the air compressor generator realizes the purpose of eliminating the need to build a fixed machine base 1 at sea.

8. The wind air compressor generator lowers the pressure of the one-way valve 12 to suppress large-capacity low-pressure compressed air, and pushes the small cylinder through the large cylinder to increase the pressure of the low-pressure compressed air, thereby reducing the length of the wind power fan 7 wings. Reduce the impact of hurricanes on wind power fans, reduce the applicable wind intensity range of wind air compressor generators, make the power fans less likely to be damaged and reduce manufacturing costs.

By lowering the pressure of the one-way valve 12, the wind air compressor generator is suitable for large-scale deployment on river banks, coasts, canyons, bridges, high-rise buildings, plains and islands with low wind intensity. The compressed air collected in an array is transported through the air pipeline network. Provide unified power generation to wind and air compressed power plants, replace thermal power plants with wind and air compressed power plants, and solve power problems in areas lacking coal, oil, and electricity.

Or electrolytic hydrogen energy supply, which can provide a continuous supply of electricity energy or electrolytic hydrogen energy to the land.
