Description

Technical Field

[0001] The invention relates to a wind power generation device, in particular to a wind power generation device capable of generating rotating wind. Background Art

[0002] At present, wind power generation is generally divided into horizontal axis generator sets and vertical axis generator sets according to their structure.

[0003] 1. For horizontal axis generator sets:

[0004] ①Advantages: compact structure, relatively mature technology, safe and reliable.

[0005] ② Disadvantages: The horizontal axis needs to adjust the direction of rotation of the wind rotor by adjusting the direction of wind (also called yaw and pitch), which makes the structure more complicated. The transmission and generator sets are installed in the working machine room at the top of the tower. Large parts cannot be replaced and repair is inconvenient. The blades, bearings and gearboxes of the horizontal axis unit are very expensive. If a major failure or typhoon occurs, the entire unit will be basically damaged and scrapped, causing significant economic losses. The horizontal axis unit has extremely high requirements for the installation foundation, and the fan blades cut the wind and make a lot of noise when the wind turbine is working.

[0006] The utilization rate of natural wind energy in the existing technology is low, and is generally limited to wind power generation in the horizontal wind direction (there is no unified utilization of wind energy from various directions), and can only be utilized in one plane. The wind power is not synthesized and converted into a vortex wind direction that continuously enhances the rotational torque like a tornado, in order to further obtain greater energy, drive the wind wheel to rotate, and maximize the power generation efficiency; there are also shortcomings in the generator system facilities. The cheap wind power generation power supply method is not used to realize the wireless Internet of Things automated remote video monitoring system, and the 24-hour all-weather video automatic monitoring method is used to manage the operating status of each wind turbine, and at the same time solve the problems of lightning protection, theft prevention, fire prevention, etc. in the jurisdiction area, in order to further improve safety protection and reduce operating costs.

[0007] 2. For vertical axis wind turbines:

[0008] ① The advantage of vertical axis wind turbines is that they can receive wind from any direction, do not require a yaw device for the wind rotor, and the mechanical transmission and generator set can be installed on the ground, making maintenance easy.

[0009] ② Disadvantages: The wind energy utilization coefficient of the vertical axis wind turbines currently on the market is not high. Due to their small size and proximity to the ground, the available wind energy is limited. If the size is slightly larger, it will be difficult to start by itself due to its own weight. For large vertical axis wind turbines, it is necessary to solve complex problems such as gravity friction and dynamic balance when the main drive structure rotates. It is impossible to enlarge vertical axis generators with the current technical level.

[0010] In addition, in the field of wind power generation, wind turbines are horizontal axis active wind-facing type, and the blades of this type of wind turbine are relatively long. For example, the length of a single blade of the most economical 3MW unit is more than 40 meters. The main way to increase the capacity of a single wind turbine is to increase the length of the blades. Continuing to increase the length of the blades is not only limited by the strength of the blades, but also increases the manufacturing cost of the engine. How to obtain greater power without increasing the size of the generator is one of the research directions in the field of wind engines.

[0011] Patent No. CN201120318357.6 discloses a wind-gathering fan, which is a fan with a gradually expanding conical wind-gathering short cylinder on the periphery of the turbine blades. Although the ratio of the front and rear diameters of the wind-gathering short cylinder is only 1.3 times, the use of this fan can increase the power generation by three times. The blades can obtain more energy with the help of the wind-gathering short cylinder. Since the turbine blades are long, the wind-gathering short cylinder needs to be sleeved on the periphery of the turbine blades, making the wind-gathering short cylinder huge in size and heavy in weight. Therefore, this wind engine can only be set on the lower ground, and cannot be set on a high mountain or a high-rise building. The scope of application is limited. In addition, since a wind-gathering short cylinder is sleeved on the periphery of the long and heavy turbine blades, the overall weight is heavier, so that the turbine and the wind-gathering short cylinder cannot rotate with the wind, and can only use wind energy in a single direction, and the utilization rate of wind energy is not high. Summary of the invention

[0012] The purpose of the present invention is to provide a wind power generation device that is simple, compact, convenient and efficient in structure and can generate rotating wind, so as to uniformly utilize wind energy from various directions and convert it into vortex wind that continuously enhances the rotating torque force like a tornado to push the wind wheel to rotate in the horizontal direction, thereby maximizing the power generation efficiency; the power generation efficiency is high, safe and reliable, and the cost is low; in order to overcome the shortcomings of the prior art, a new solution is provided.

[0013] In order to solve the above technical problems, the technical solution of the present invention is:

[0014] This wind power generation device capable of generating rotating wind has a conical appearance and comprises: a main body formed by three semi-conical enclosure devices with the same structure fixedly connected to each other, the lower ends of the three enclosure devices are each provided with a rotating wind outlet, the three rotating wind outlets are commonly fixedly connected to an air collecting pipe, and the strong wind force generated by the air collecting pipe is used to drive the wind wheel to drive the generator to generate electricity.

[0016] A flow guiding groove 5 is arranged on the swirl plate.

[0018] The air inlet plate is fixedly connected to the swirl plate along the top of the swirl plate. The unfolded shape of the swirl plate is an unequal fan shape. The middle part of the swirl plate is convex, and the convex part is a plurality of guide grooves in the shape of strips. One side of the swirl plate is fixedly connected to the swirl plate 2 of another enclosure device, and the other side of the swirl plate is fixedly connected to one side of the spoiler.

[0019] A vibration air inlet and a spoiler air inlet are fixedly installed on the upper and lower parts of the spoiler respectively. Two large-leaf movable plates are provided in the vertical direction of the vibration air inlet. One end of the large-leaf movable plate is fixedly installed on the spoiler, and the other end of the large-leaf movable plate is separated from the spoiler. The large-leaf movable plate is arranged obliquely toward the inside of the enclosure device; a small-leaf movable plate is provided in the spoiler air inlet, and the top end of the small-leaf movable plate is fixedly connected to the spoiler; the other side of the spoiler is fixedly connected to the swirl plate of another enclosure device.

[0020] The air inlet plate is in an isosceles fan shape; the guide convex groove provided on the swirl plate has a convex height of 4-6 cm and a width of 3-4 cm.

[0021] The arc length of the top of the swirl plate is 0.9-1 meter, and the arc length of the bottom of the swirl plate is 0.11-0.14 meter; the left waist length of the swirl plate is 1.2-1.5 meters, and the right waist length of the swirl plate is 1.1-1.3 meters.

[0022] The arc length of the top of the air inlet plate is 0.9-1 meter, and the arc length of the bottom of the air inlet plate 1 is 0.7-0.75 meter; the lengths of the left and right waists of the air inlet plate are both 0.34-0.36 meter.

[0023] The air inlet is an opening formed by the air inlet plate, the swirl plate and the spoiler being fixedly connected to each other. The natural wind from the southeast, northwest and center directions of the outside world is refracted into the air inlet through the air inlet plate and enters the enclosure device through the air inlet.

[0024] The adjustable vibration air inlet and spoiler air inlet provided on the spoiler are used for natural wind from various directions to enter the enclosure device.

[0028] The angle between the outer edge of the air inlet plate and the swirl plate is 120-140 degrees; the length ratio of the outer edge of the air inlet plate to the outer edge of the swirl plate is: 0.9-1.1:4.8-5.2.

It utilizes wind energy from all directions in a unified manner and converts it into a vortex wind that continuously increases the rotating torque force like a tornado to drive the wind wheel to rotate, thereby maximizing the power generation efficiency. It has high power generation efficiency, is safe and reliable, and has low cost.

[0031] Taking advantage of the characteristics of the vertical axis generator set that can receive wind from all directions, this device guides and outputs wind energy in a fixed horizontal direction through a special channel. This directional wind force is used to drive the new impeller by rotating the horizontal axis, and the output mechanical energy drives the generator set, which no longer needs to be equipped with a yaw and propeller device, thereby improving the working efficiency of the equipment. In addition, the mechanical transmission and generator set can be placed on the ground, which is extremely convenient for installation and maintenance.

[0032] The present invention solves the shortcomings of low working efficiency of horizontal axis generator sets, difficult maintenance of high-altitude equipment, high requirements for installation foundation, and low power and low wind energy utilization rate of vertical axis generator sets. Through experimental measurements, no matter what wind direction, when the wind speed enters the device at 4.8 meters per second, a fixed-direction wind force of 3.8 meters per second can be obtained after conversion. If the device is constructed in a wind field where the average wind force reaches more than 15 meters per second throughout the year, it will have great social and economic value.

[0033] The advantages of the present invention combine the advantages of vertical axis generator sets and horizontal axis generator sets, taking advantage of the fact that vertical axis generator sets are not restricted by wind direction, and taking advantage of the mature mechanical transmission structure of horizontal axis wind turbine sets to fully utilize the efficiency of wind power and equipment, solving the requirements for the foundation during installation of the horizontal axis and the difficulties in transportation and hoisting.

The device of the present invention does not require yaw and yaw devices, and the working compartment of the horizontal axis generator set can be placed on the ground, which is convenient for installation and maintenance, reduces transportation conditions, and allows the construction of a very powerful generator set. The present invention will have a great impact on the existing wind power generation market, and will bring new changes to the existing market in terms of production management, production efficiency, and economic benefits.

[0079] Working principle:

[0080] The technical structure of the present invention is to build an arc-shaped foundation device that can accept wind from all directions (a variety of composite materials and concrete can be used);

[0081] To guide the wind coming from all directions, ① the air inlet plate 1 is the main wind receiving plate, ② the swirl plate 2 includes: an arc-shaped main body curved auxiliary rib plate, a streamlined guide strip (groove), ③ the spoiler 8 is an auxiliary spoiler, ④ the rotating wind outlet 4, the air collecting pipe 12 is the rotating wind outlet and other facilities. The device of the present invention can adjust the unidirectional wind into a cyclone with rotating power, and convert it into a stable horizontal wind output through a special arc channel. The basic angle between ① the air inlet plate 1 of the main wind receiving plate and ② the swirl plate 2 of the arc-shaped main body is 130 degrees (adjustable), and the length ratio of the main wind receiving plate to the arc-shaped main body is 1:5.

[0082] The device of the present invention utilizes an all-round vertical wind guiding and collecting device with a main body of three-page structure to collect and guide wind in a nearly vertical manner. The pages are specially designed with curved surfaces to guide natural wind into the device as much as possible to improve the utilization rate of wind power. Natural wind enters the device from ① the air inlet plate 1 of the main wind receiving plate, accounting for four-fifths of the total flow rate. The remaining one-fifth of the flow rate enters from the spoiler port of ③ the spoiler plate 8 to generate a wind force difference with the main air inlet to form a rotating vortex. The rotating wind force is then guided to ④ the rotating wind output port 4 and the outlet of the air collecting pipe 12 through the internal downward arc-shaped guide strips (grooves). ② is the curved secondary rib plate of the swirl plate 2 of the arc-shaped main body. Because the natural wind force has uncertainty in the direction, the wind force needs to be adjusted through the guide strips and spoilers.

[0083] Spoiler 8, guide groove principle and proportion: on the windward side of each curved surface, specially designed curved secondary ribs are arranged to enhance wind guidance and wind collection, so as to achieve the purpose of guiding the wind in the right direction and collecting the maximum possible amount of wind. The ratio of the curved secondary rib guide strip to the overall curved secondary rib is about 1:15. Through the above-mentioned structural adjustment, after the natural wind enters the wind collecting device, the upper and lower winds will produce a wind force difference, thereby causing the wind force to rotate, superimposed and enhanced on each other, forming a cyclone with a fixed axial flow direction to guide it to the conversion fan blade device. Through experimental measurement, regardless of any wind direction, when the wind speed enters the device at 4.8 m / s, after conversion, a fixed horizontal axis wind force of 3.8 m / s can be obtained, and then the specially designed wind wheel of the present invention is driven to generate mechanical energy to drive the large generator set to complete power generation. The normal working wind speed range of the device of the present invention is designed to be 3 m / s-28 m / s. The present invention also takes into account that due to the different conditions of wind fields in different places, the main air receiving plate and the spoiler can adjust the wind inlet angle. The adjustable angle between the main air receiving plate and the main body is about 15°, and the spoiler can be adjusted to 21°, which ensures the fixed flow output after the coordination of the main air inlet air volume and the spoiler air volume, and designs a series of adjustable air discharge ports on the main arc back plate to avoid the impact of the super typhoon on the device.

[0084] Production process: mainboard wind collection → spoiler coordination → merging to form a cyclone → channel output → special wind wheel → generator set → output current grid connection

[0085] Production conditions: China has a long coastline. This device can be built on uninhabited coastal tidal flats without occupying good land and being unaffected by typhoons.

[0086] The actual production scheme of the present invention is as follows: my country has a long coastline, which is an excellent wind farm. The present invention can build the cyclone wind power station in uninhabited areas or tidal flats along the coast of China (without occupying good land) with stable foundations. As long as funds allow, a 2-3 megawatt {i.e. 2000 kilowatts-3000 kilowatts} level wind power plant can be built, and the wind power plant of the present invention can be replicated without restriction.
