Description

Technical Field

[0001] This invention relates to the field of wind energy conversion technology, specifically a wind energy conversion device for pastoral areas. Background Technology

[0002] Wind energy is the kinetic energy generated by the movement of large amounts of air on the Earth's surface. Due to the different temperature changes and water vapor content in the air caused by solar radiation in different parts of the ground, there are differences in air pressure in different places. High-pressure air flows from low-pressure areas in the horizontal direction, which forms wind.

[0003] Wind energy conversion devices are mainly used in rural areas, pastoral areas, and mountainous areas, as well as near developing large, medium, and small cities or commercial areas to meet the electricity needs of local users. Wind power generation technology is clean and pollution-free, which plays a role in promoting my country's sustainable development strategy. However, most existing wind energy conversion devices used in pastoral areas are horizontal axis wind energy conversion devices. Some large horizontal axis wind energy conversion devices have a relatively complex structure, occupy a large area, and have large blades, resulting in high installation costs. The blades on the wind energy conversion devices are exposed high-speed rotating components, and large blades can easily injure birds and other flying animals. On the other hand, some small horizontal axis wind energy conversion devices are lighter and are easily blown over or even blown away by strong winds. They are also not easy to operate in weak winds.

[0004] When using wind energy conversion devices in pastoral areas at higher altitudes and latitudes, the low temperatures and high humidity in winter can easily lead to icing on the blades of the wind energy conversion devices. When the blades are iced, the uneven height of the blade surface can increase the load on the blades and increase the resistance, thus affecting the operating quality of the wind energy conversion device. In severe cases of icing or in extreme weather, the blades cannot be effectively protected, which can damage the wind energy conversion device and its blades. Therefore, we propose a wind energy conversion device for pastoral areas. Summary of the Invention

[0005] In view of the problems existing in the prior art, the present invention discloses a wind energy conversion device for pastoral areas, the technical solution of which includes a support platform and a folding unit;

[0006] Support platform: Mounting holes are arranged in a circumferential array at equal intervals on its top and bottom. A circular through groove is provided in the center of the support platform. A wind tunnel unit is positioned directly above the circular through groove. A rotating unit is fixedly mounted on the top of the wind tunnel unit. A first wind energy conversion unit is arranged inside the wind tunnel unit. The first wind energy conversion unit is fixedly connected to the bottom of the rotating unit. A fan blade is positioned on the top of the rotating unit. An annular connecting boss is provided on the inner bottom of the fan blade. The inner side of the annular connecting boss is rotatably connected to the top of the rotating unit. A conical top is provided on the top surface of the fan blade. The circular through groove... A booster unit is located directly below, and a second wind energy conversion unit is installed inside the booster unit. The internal structure of the wind duct unit and the booster unit can be connected through a circular through slot on the support platform. The installation holes facilitate the installation of the wind duct unit and the booster unit by the staff. The annular connecting boss facilitates the rotation of the fan blades along the rotating unit. The rotating unit drives the first wind energy conversion unit to generate electricity. The conical top prevents rain and snow from accumulating on the top of the fan blades. The cooperation between the wind duct unit and the booster unit drives the second wind energy conversion unit to generate electricity.

[0007] The folding unit comprises a first fixed platform, an electric telescopic rod, a fourth bearing, a connecting block, a first connecting rod, a first pin, a second pin, a second connecting rod, a slide rod, a slide groove, a U-shaped connecting plate, fan blades, a pipe air bag fixing groove, a fixing block, a telescopic rod, and a first compression spring. The first fixed platform is fixedly installed in the middle of the inner side of the rotating unit. An electric telescopic rod is fixedly installed at the top center of the first fixed platform. A telescopic rod is positioned directly above the electric telescopic rod. Connecting blocks are respectively provided at the upper and lower ends of the telescopic rod. A first compression spring is positioned between the connecting blocks and is fitted onto the outer side of the telescopic rod. A fixing block is provided at the top of one of the connecting blocks, and the top of the fixing block is fixedly connected to the top of the inner side of the fan blade cylinder. The bottom of the other connecting block is rotatably connected to the telescopic end of the electric telescopic rod through the fourth bearing. Five sets of first and second connecting rods are arranged in a circular array at equal intervals.

Fan blades are fixedly installed on the outside of the U-shaped connecting plate. The middle of the left and right sides of the fan blades are arc-shaped structures, and the upper and lower ends of the fan blades are semi-oval structures. The upper and lower ends of the left and right sides of the fan blades are respectively provided with pipe air bag fixing grooves. The input end of the electric telescopic rod is electrically connected to the output end of an external power supply. The electric telescopic rod can be fixed by the first fixed platform. The electric telescopic rod allows the connecting block at the top of the rod to move up and down, thus extending and retracting the rod. This design also prevents the first compression spring from bending and deforming when compressed. The cooperation between the first connecting rod, first pin, second pin, second connecting rod, sliding rod, and sliding groove allows the U-shaped connecting plate to move the fan blades outward or retract. When the U-shaped connecting plate retracts the fan blades, and the surface of the blades is covered with ice, the first compression spring increases the load on the electric telescopic rod during retraction, helping the U-shaped connecting plate retract the fan blades. The pipeline air bag fixing groove secures the pipeline air bag.

The top of the venturi tube has a contraction section, and the inner top of the contraction section has a spiral array of guide plates. The middle of the venturi tube has a throat, and the bottom of the venturi tube has a diffuser section. Through the coordinated arrangement of the venturi tube, contraction section, guide plate, throat, and diffuser section, when wind passes through the contraction section, the guide plate can guide the wind at the contraction section to form a vortex rotation, thereby increasing the wind velocity moving towards the throat. Through the Venturi effect, the wind velocity is further increased when the wind enters the throat, and the wind velocity decreases when the wind moves to the diffuser section. The second fixing bolts can be used to fix the venturi tube.

[0011] As a preferred technical solution of a wind energy conversion device for pastoral areas according to the present invention, the first ice crushing unit includes a second fixed platform, a telescopic airbag, a first connecting pipe, a second connecting pipe, a fixed pipe, a pipeline air bag, and a second compression spring.

The first ice-crushing unit is mounted on the rotating cylinder via a second fixed platform, allowing it to rotate with the cylinder. Through the coordinated arrangement of the telescopic airbag, the first connecting pipe, the fixed pipe, and the second connecting pipe, the gas inside the telescopic airbag is delivered to the pipeline air bag.

When the pressure at one end of the rotating plate changes, the rotating plate rotates along the third pin on the U-shaped fixed block, while the ice crushing roller at the other end of the rotating plate makes close contact with the surface of the fan blade. When the fan blade retracts, the ice crushing roller rotates along the fourth pin, and the spherical protrusions on the surface of the ice crushing roller crush the ice covering the fan blade.

The first turbofan is located in the middle of the first rotating shaft. The top of the first rotating shaft is fixedly connected to the bottom of the transmission shaft via a coupling. The coupling allows the transmission shaft to drive the first rotating shaft to rotate when it rotates. Through the cooperation between the first rotating shaft, the first turbofan, and the second fixed frame, the first turbofan rotates when the first rotating shaft rotates. The first turbofan blows air into the wind tunnel unit at the pressure boosting unit. Simultaneously, the rotation of the first rotating shaft drives the first generator to generate electricity.

[0014] As a preferred technical solution of the wind energy conversion device for pastoral areas according to the present invention, the second wind energy conversion unit includes a second fixed frame, a second generator, a third fixed frame, a second rotating shaft, and a second turbofan. The second fixed frame is fixedly installed at the bottom inner side of the throat, and the second generator is fixedly installed at the top of the second fixed frame. Two third fixed frames are provided, one fixedly installed at the middle inner side and the other at the top of the throat.

[0015] As a preferred technical solution of the wind energy conversion device for pastoral areas according to the present invention, five blade scraper sleeves are arranged in a circumferential array at equal intervals on the top of the fan blade cylinder, and the inner surface of the blade scraper sleeves is in active contact with the outer surface of the fan blades. The blade scraper sleeves can remove crushed ice from the fan blades.

[0016] As a preferred technical solution of the wind energy conversion device for pastoral areas according to the present invention, it further includes connecting rods and a mesh plate. The connecting rods are arranged in a circular array at equal intervals at the bottom end of the venturi tube, and the mesh plate is fixedly installed at the bottom of the connecting rods.

[0017] As a preferred technical solution of the wind energy conversion device for pastoral areas according to the present invention, support legs are fixedly installed at the four corners of the bottom of the support platform, reinforcing ribs are respectively provided in the middle between the support legs, fixing holes are respectively provided at the bottom of the support legs, and a guardrail is provided at the top of the support platform. The support legs provide support for the support platform; the fixing holes facilitate the use of external helical ground stakes for fixing; the reinforcing ribs improve the structural stability between the support legs; and the guardrail protects the workers assembling the device on the support platform.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: The wind energy conversion device used in this pastoral area has the following advantages:

[0019] 1. The wind energy conversion device used in this pastoral area forms a wind duct between the first and second wind ducts through a partition installed between them. This allows wind from the outside to enter the space between the first and second wind ducts from any direction. The wind is guided into the Venturi tube by the design of the wind-guiding arc surface. When the wind enters the Venturi tube, it first passes through the top of the inner side of the contraction section. The wind guide plate at the contraction section guides the wind to rotate in a vortex, thereby increasing the wind speed as it moves towards the throat. Through the Venturi effect, the wind speed is further increased when the wind enters the throat, causing the second turbine fan to drive the second shaft to rotate. By installing two second turbine fans, the utilization rate of the wind by the second turbine fans can be improved, thereby increasing the rotation speed of the second shaft. The rotation of the second shaft drives the second generator to generate electricity.

[0020] 2. When the rotating drum rotates, the internal gear ring can drive the driven gear to rotate. Through the meshing of the teeth on the driven gear and the transmission gear, the rotation speed of the transmission gear can be further increased. The rotation of the transmission gear causes the transmission shaft to rotate at high speed along the third bearing. The transmission shaft is connected to the first rotating shaft through the coupling, so that the first rotating shaft drives the first turbofan to rotate. Through the setting of the first turbofan, the air blown into the air duct unit can be blown to the pressurization unit for pressurization. At the same time, when the first rotating shaft rotates, it can drive the first generator to generate electricity.

[0021] 3. When the electric telescopic rod extends upward, the connecting block at the top of the electric telescopic rod moves upward, and the telescopic rod shortens. As the connecting block moves upward, the first compression spring is compressed and deformed, causing the first connecting rod to push the second connecting rod upward through the second pin. The upper and lower ends of the first connecting rod rotate with the protrusion on the connecting block and the top of the U-shaped connecting plate through the first pin. When the second connecting rod moves upward, the top end of the second connecting rod rotates with the connecting block at the bottom of the fixed block through the first pin. The sliding rod at the bottom of the second connecting rod slides along the slide groove, thereby pushing the U-shaped connecting plate to drive the fan blades to move outward. The upper and lower ends of the fan blades are semi-oval structures, thereby reducing wind resistance. The left and right sides of the fan blades are arc-shaped structures, which facilitates the fan blades being blown by the external wind and causes the fan blades to drive the rotating cylinder to rotate, thereby facilitating the rotating unit to drive the first wind energy conversion unit to generate electricity.

[0022] 4. By retracting the electric telescopic rod, the U-shaped connecting plate drives the fan blades to retract into the fan blade cylinder. The U-shaped connecting plate can compress the telescopic airbag, and the gas in the telescopic airbag is transported to the fixed pipe through the first connecting pipe. The fixed pipe then transports the gas to the pipeline air bag through the second connecting pipe. The expansion and contraction of the pipeline air bag can break the ice layer covering the fan blades. When the fan blades retract, the ice crushing roller rotates along the fourth pin shaft. The spherical protrusions on the surface of the ice crushing roller crush the ice covering the fan blades. The fan blade scraper sleeve makes contact with the outer surface of the fan blades. When the fan blades retract, the fan blade scraper sleeve can scrape off the crushed ice on the fan blades.

[0023] 5. The wind energy conversion device used in this pastoral area occupies a small area, is easy to install, has a low operating cost, and has a high wind energy conversion efficiency. It can pressurize and utilize even small wind forces, greatly improving the operational quality of the wind energy conversion device. At the same time, it is less likely to harm flying animals. In the cold winter, it can clear the ice layer and ice blocks covering the blades, and the blades can be retracted into the device, thus effectively protecting the blades and the wind energy conversion device.

The support legs 14 can support the support platform 1 to a certain height, so as to facilitate the exhaust of the pressurization unit 4. The support legs 14 are fixed by the workers through the fixing holes 15 using external spiral ground stakes, so as to prevent the device from being blown over by strong winds. The reinforcing ribs 16 can improve the structural stability between the support legs 14 and protect the pressurization unit 4 from being scratched or bumped by grazing animals in the pasture. The guardrail 17 can protect the workers who assemble the device on the support platform 1.

[0056] The working principle of this invention is as follows: First, the device is placed in a suitable working position. Workers use external spiral ground stakes to pass through the fixing holes 15, thereby fixing the support legs 14 and preventing them from being blown over by strong winds. The reinforcing ribs 16 improve the structural stability between the support legs 14 and protect the pressurization unit 4 from being scratched or bumped by grazing animals. The guardrail 17 protects the workers assembling the device on the support platform 1. The first fixing bolts 206 allow workers to connect them through the through holes at the bottom of the first air duct 201 to the mounting holes 21 at the top of the support platform 1, thus securing the first air duct 201. 1. For fixation, the partition 205 installed between the first air duct 201 and the second air duct 202 can connect the second air duct 202 and the first air duct 201 into a whole, forming an air duct between them. This allows external wind to be blown into the space between the first air duct 201 and the second air duct 202 from any direction. The air guide arc surface 204 guides the wind blown into the space between the first air duct 201 and the second air duct 202 into the venturi tube 401. The second fixing bolt 404 can be passed through the through holes on the venturi tube 401 and connected to the mounting holes 21 at the bottom of the support platform 1, thereby fixing the venturi tube 401. When the air passes through the Venturi tube 401, it first passes through the inner top of the contraction section 402. The guide plate 403 at the contraction section 402 guides the air to vortex and rotate, increasing the airflow velocity towards the throat 405. Through the Venturi effect, the airflow velocity is further increased when the air enters the throat 405, causing the second turbofan 905 to drive the second shaft 904 to rotate. The presence of two second turbofans 905 improves the utilization rate of the airflow, thereby increasing the rotational speed of the second shaft 904. The rotation of the second shaft 904 drives the second generator 902 to generate electricity. The generator is mounted on the first fixed frame 203 via a fixed pipe 301. The annular connecting plate 302 in the middle is connected to the second air duct 202, so that the fixed pipe 301, the annular connecting plate 302, and the air duct unit 2 form a whole. The fixed plate 311 supports the driven gear 307, the transmission gear 308, the third bearing 310, and the transmission shaft 312. Simultaneously, the fixed plate 311 supports and fixes the first fixed platform 501. The second bearing 304 allows the rotating cylinder 305 to rotate along the fixed pipe 301. When the rotating cylinder 305 rotates, the internal gear ring 306 drives the driven gear 307 to rotate. Through the meshing of the teeth on the driven gear 307 and the transmission gear 308, the rotational speed of the transmission gear 308 can be further increased.The transmission gear 308 drives the transmission shaft 312 to rotate at high speed along the third bearing 310. The transmission shaft 312 is connected to the first rotating shaft 804 via a coupling 805, causing the first rotating shaft 804 to drive the first turbofan 803 to rotate. The first turbofan 803 directs the air blown into the air duct unit 2 towards the pressurization unit 4. Simultaneously, the rotation of the first rotating shaft 804 drives the first generator 802 to generate electricity. The first bearing 303 allows the top center of the rotating cylinder 305 to be rotatably connected to the outer side of the fixed end of the electric telescopic rod 502. When the electric telescopic rod 502 extends upwards, the connecting block 504 at the top of the electric telescopic rod 502 moves upwards, while the telescopic rod 515 shortens. 04. Moving upwards, the first compression spring 516 is compressed and deformed, causing the first connecting rod 505 to push the second connecting rod 508 upwards via the second pin 507. The upper and lower ends of the first connecting rod 505 rotate with the protrusion on the connecting block 504 and the top of the U-shaped connecting plate 511 via the first pin 506. When the second connecting rod 508 moves upwards, its top end rotates with the connecting block 504 at the bottom of the fixing block 514 via the first pin 506. The sliding rod 509 at the bottom of the second connecting rod 508 slides along the sliding groove 510, thereby pushing the U-shaped connecting plate 511 to drive the fan blade 512 outwards. The fan blade 512 has a semi-oval structure at both its upper and lower ends, reducing wind resistance. The fan blade 512's left and right ends... The side has an arc-shaped structure, which facilitates the fan blades 512 being blown by external wind, and causes the fan blades 512 to drive the rotating cylinder 305 to rotate. By retracting the electric telescopic rod 502, the U-shaped connecting plate 511 causes the fan blades 512 to retract into the fan blade cylinder 18. The retraction of the U-shaped connecting plate 511 can compress the telescopic airbag 602. When the telescopic airbag 602 is compressed, the gas inside the telescopic airbag 602 is transported to the fixed pipe 605 through the first connecting pipe 603. The fixed pipe 605 then transports the gas to the pipeline air bag 606 through the second connecting pipe 604. The expansion and contraction of the pipeline air bag 606 can break the ice layer covering the fan blades 512. When the U-shaped connecting plate 511 extends, the second compression spring 60... Under the action of 7, the interior of the telescopic airbag 602 expands and returns to its original shape, and the gas in the pipeline airbag 606 returns to the telescopic airbag 602 along the original path. When the pressure at one end of the rotating plate 707 changes, the rotating plate 707 rotates along the third pin 706 on the U-shaped fixed block 705, while the ice crushing roller 708 at the other end of the rotating plate 707 makes close contact with the surface of the fan blade 512. When the fan blade 512 retracts, the ice crushing roller 708 rotates along the fourth pin 709, and the spherical protrusions on the surface of the ice crushing roller 708 crush the ice covering the fan blade 512. Through the active contact between the fan blade scraper sleeve 11 and the outer surface of the fan blade 512, the fan blade scraper sleeve 11 can scrape off the crushed ice on the fan blade 512 when the fan blade 512 retracts.By electrically connecting the first generator 802 and the second generator 902 to an external inverter and battery pack, the electrical energy converted by the device can be stored and utilized.
