Description

Technical Field

[0001] This invention relates to the field of wind turbines, specifically to a new energy wind turbine that can track wind direction and its power generation method. Background Technology

[0002] A wind turbine is an electrical device that converts wind energy into mechanical work, which drives the rotor to rotate and ultimately outputs alternating current. A wind turbine generally consists of components such as a wind turbine, generator, tail fin directional control, tower, speed limiting safety mechanism, and energy storage device.

[0003] Currently, existing wind turbines generally adjust the direction of the rotor through a tail fin directional control device. This allows for synchronous adjustment with the wind direction, thereby improving power generation efficiency. However, when the wind direction is chaotic, the wind turbine will swing frequently according to the chaotic wind direction. This can easily cause rapid wear of the transmission mechanism. At the same time, the tail fin does not have the function of dissipating force and is continuously subjected to the impact of airflow pressure, which can easily cause the connection to break, thus reducing its service life. Summary of the Invention

[0004] The purpose of this invention is to provide a new energy wind turbine generator that can track wind direction and its power generation method, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a new energy wind turbine generator capable of tracking wind direction, comprising...

[0006] A column, the top of which is fixedly installed with a housing, and the wind turbine body is installed inside the housing. The output shaft of the wind turbine body passes through the left side of the housing and is connected to the generator blades.

[0007] The outer side of the housing away from the generator fan blades is integrally formed with an air guide shroud. The air guide shroud is equipped with a tracking mechanism, which includes a lead screw, a fan blade, and a folding baffle.

[0008] The housing has a positioning mechanism inside on the side near the air guide cover. The positioning mechanism includes a swing arm, a positioning plate and a positioning sensor. The end of the swing arm near the air guide cover is threadedly connected to a lead screw.

[0009] Cleaning mechanisms are provided on both sides of the air guide cover. The cleaning mechanism includes a protective net, a transmission rod and a scraper. A directional adjustment mechanism is provided between the top of the column and the bottom of the outer shell. The directional adjustment mechanism includes a reduction motor, a transmission frame and a drive gear. A driven gear is fixedly installed at the bottom middle part of the outer shell through a transmission shaft.

[0010] Furthermore, a lead screw is provided in the middle of the inner side of the air guide shroud, and air guide fan blades are fixedly installed at both ends of the lead screw. A swing groove is provided between the outer shell and the air guide shroud, and a folding baffle is provided on the side of the swing groove near the air guide shroud. The middle part of the swing arm is fixedly connected to the folding baffle.

[0011] Furthermore, positioning sensors are provided at both ends of the inner side of the outer shell near the air guide cover, and a positioning plate is fixedly installed on the side of the swing arm near the positioning sensor, with the positioning plate and the positioning sensor on the same horizontal line.

[0012] Furthermore, a side groove is provided on the inner wall of the side of the air guide shroud away from the outer shell, and a fixing rod is fixedly installed inside the side groove. The end of the swing arm away from the positioning plate is movably connected to the fixing rod through the rod groove.

[0013] Furthermore, a support rod is fixedly installed in the middle of the swing groove, the swing arm is movably connected to the support rod, and springs are provided on both sides of the swing arm near the support rod. The springs are movably connected to the support rod, and the end of the spring away from the swing arm is fixedly connected to the swing groove.

[0014] Furthermore, a protective net is provided on the outer side of the air guide shroud near the two air guide fan blades, and a scraper is fixedly installed at the end of the transmission rod away from the air guide fan blades through the protective net. The inner surface of the scraper is slidably connected to the outer surface of the protective net.

[0015] Furthermore, a transmission frame is fixedly installed at the top of the column, and a reduction motor is fixedly installed on the outside of the bottom right side of the transmission frame. The output shaft of the reduction motor passes through the transmission frame and a drive gear is fixedly installed thereon. The drive gear meshes with the driven gear.

[0016] Furthermore, a guide groove is provided in the middle bottom of the outer shell, and dampers are provided at the four corners of the top of the transmission frame. Each of the four dampers has a pulley at its output shaft end, and the four pulleys are movably connected inside the guide groove.

[0017] Furthermore, limiting plates are fixedly installed on both sides of the bottom end of the pulley, and annular grooves are provided on both sides of the inner wall of the guide groove, with the limiting plates slidably connected to the annular grooves.

[0018] A power generation method for a new energy wind turbine that can track wind direction:

[0019] Step 1: When the airflow enters from any side of the air guide shroud, it will blow the fan blades in that direction. The fan blades will rotate due to the wind force, which will then control the lead screw on one side to rotate synchronously. After the lead screw rotates, it will drive the swing arm to move laterally in the direction of the fan blades at that position. After the swing arm moves, the positioning plate at the other end of the swing arm will gradually approach the positioning sensor. When the positioning sensor detects the positioning plate, it will control the reduction motor to start.

[0020] Step 2: After the geared motor starts, it drives the drive gear at one end of the transmission frame to rotate. After the drive gear rotates on one side of the transmission frame, it will drive the driven gear on the other side to rotate synchronously. After the driven gear rotates, it drives the top shell to rotate synchronously through the transmission shaft, thereby controlling the wind turbine body inside the shell to adjust its position until the generator blades at the output shaft end of the wind turbine body are adjusted to face the wind direction.

[0021] Step 3: When the fan blades at this position rotate, the transmission rod installed at its end will drive the scraper located outside the protective net to rotate synchronously. When the scraper rotates at this position, it can clean the debris covering the surface of the protective net, avoid clogging the protective net, and allow the wind to pass through the air guide cover normally.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. When airflow enters from any side of the air guide shroud, it blows the air guide fan blades in that direction. The air guide fan blades rotate under the influence of the wind force, which in turn controls the lead screw on one side to rotate synchronously. After the lead screw rotates, it drives the swing arm to move laterally in the direction of the air guide fan blades at that position. Due to the structural characteristics of the air guide fan blades, when the air guide fan blades move, the gas leaks out through the gaps or edges of the blades, which helps to reduce the resistance when the blades move and avoids the connection from breaking when under continuous stress, thereby improving its service life.

[0024] 2. When the guide fan blades are blown by the wind, the screw will rotate rapidly. The swing arm is located inside the swing groove. By applying a reverse thrust, the swing arm moves smoothly in the lateral direction. When the wind is too weak, the guide fan blades will not rotate due to the reverse thrust of the spring. This can reduce the interference of weak airflow when the wind direction is chaotic. Only when the wind reaches a certain level can the guide fan blades drive the swing arm to move.

[0025] 3. When the fan blades of this invention rotate, the transmission rod installed at its end will drive the scraper located outside the protective net to rotate synchronously. When the scraper rotates, it can clean the debris covering the surface of the protective net, avoid clogging the protective net, and allow the wind to pass through the air guide cover normally.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figure 1-5This invention provides a technical solution: a new energy wind turbine generator capable of tracking wind direction, comprising a column 1, a housing 2 fixedly installed at the top of the column 1, a wind turbine generator body 3 disposed inside the housing 2, and a generator fan blade 4 connected to the output shaft of the wind turbine generator body 3 passing through the left side of the housing 2; an air guide shroud 5 integrally formed on the side of the housing 2 away from the generator fan blade 4, a tracking mechanism 6 disposed inside the air guide shroud 5, the tracking mechanism 6 including a lead screw 601, a guide fan blade 602, and a folding baffle 603; a positioning mechanism 7 disposed inside the side of the housing 2 near the air guide shroud 5, the positioning mechanism 7 including a swing arm 701, a positioning plate 702, and a positioning sensor 703, the end of the swing arm 701 near the air guide shroud 5 being threadedly connected to the lead screw 601; and cleaning mechanisms 8 disposed on both sides of the air guide shroud 5, the cleaning mechanisms 8 including protective nets. 801, transmission rod 802 and scraper 803; a directional mechanism 9 is provided between the top of the column 1 and the bottom of the outer shell 2. The directional mechanism 9 includes a reduction motor 901, a transmission frame 902 and a drive gear 903. A driven gear 10 is fixedly installed at the bottom of the middle part of the outer shell 2 through a transmission shaft; a lead screw 601 is provided in the middle of the inner side of the air guide shroud 5. Air guide fan blades 602 are fixedly installed at both ends of the lead screw 601. A swing groove 11 is provided between the outer shell 2 and the air guide shroud 5. A folding baffle 603 is provided on the side of the swing groove 11 near the air guide shroud 5. The middle part of the swing arm 701 is fixedly connected to the folding baffle 603; a positioning sensor 703 is provided at both ends of the inner side of the outer shell 2 near the air guide shroud 5. A positioning plate 702 is fixedly installed on the side of the swing arm 701 near the positioning sensor 703. The positioning plate 702 and the positioning sensor 703 are on the same horizontal line.

[0034] In this embodiment, when airflow enters from any side of the air guide shroud 5, it blows the air guide fan blade 602 in that direction. The air guide fan blade 602 rotates under the influence of the wind, which in turn controls the lead screw 601 on one side to rotate synchronously. After the lead screw 601 rotates, it drives the swing arm 701 to move laterally towards the air guide fan blade 602 at that position. After the swing arm 701 moves, the positioning plate 702 at its other end gradually approaches the positioning sensor 703. When the positioning sensor 703 detects the positioning plate 702, it controls the reduction motor 901 to start. Due to the structural characteristics of the air guide fan blade 602, when the air guide fan blade 602 moves, the gas leaks out through the gaps or edges of the blade, which helps to reduce the resistance when the blade moves and avoids the connection from breaking when under continuous force, thereby improving its service life.

[0035] like Figure 5 As shown, a side groove 12 is provided on the inner wall of the side of the air guide shroud 5 away from the outer shell 2. A fixing rod 13 is fixedly installed inside the side groove 12. The end of the swing arm 701 away from the positioning plate 702 is movably connected to the fixing rod 13 through the rod groove 14.

[0036] In this embodiment, when the lead screw 601 drives the swing arm 701 to move laterally, the rod groove 14 at one end of the swing arm 701 will slide and guide along the surface of the fixed rod 13, which can keep the swing arm 701 at a horizontal angle.

[0037] like Figure 4 As shown, a support rod 15 is fixedly installed in the middle of the swing groove 11. The swing arm 701 is movably connected to the support rod 15. Springs 16 are provided on both sides of the swing arm 701 near the support rod 15. The springs 16 are movably connected to the support rod 15. The end of the spring 16 away from the swing arm 701 is fixedly connected to the swing groove 11.

[0038] In this embodiment, when the guide fan blade 602 is blown by the wind, it will drive the lead screw 601 to rotate rapidly. The swing arm 701 is located inside the swing groove 11. One end of the swing arm 701 is subjected to a reverse thrust through 16, so that the swing arm 701 moves smoothly in the lateral direction. When the wind force is too small, due to the limitation of the reverse thrust of the spring, the guide fan blade 602 will not rotate due to the small airflow. It can reduce the interference of small airflow when the wind direction is chaotic. Only when the wind force reaches a certain level can the guide fan blade 602 drive the swing arm 701 to move.

[0039] like Figure 5 As shown, a protective net 801 is provided on the outer side of the air guide shroud 5 near the two air guide fan blades 602. The end of the transmission rod 802 away from the air guide fan blades 602 passes through the protective net 801 and is fixedly installed with a scraper 803. The inner surface of the scraper 803 is slidably connected to the outer surface of the protective net 801.

[0040] In this embodiment, when the fan blade 602 rotates, the transmission rod 802 installed at its end will drive the scraper 803 located outside the protective net 801 to rotate synchronously. When the scraper 803 rotates, it can clean the debris covering the surface of the protective net 801, avoid clogging the protective net 801, and allow the wind to pass through the air guide cover 5 normally.

[0041] like Figure 1 and Figure 3 As shown, a transmission frame 902 is fixedly installed at the top of the column 1, and a geared motor 901 is fixedly installed on the outside of the bottom right side of the transmission frame 902. The output shaft of the geared motor 901 passes through the transmission frame 902 and a drive gear 903 is fixedly installed thereon. The drive gear 903 meshes with the driven gear 10.

[0042] In this embodiment, after the geared motor 901 starts, it drives the drive gear 903 at one end of the transmission frame 902 to rotate. After the drive gear 903 rotates on one side of the transmission frame 902, it will drive the driven gear 10 meshing on the other side to rotate synchronously. After the driven gear 10 rotates, it drives the outer shell 2 at the top to rotate synchronously through the transmission shaft, thereby controlling the wind turbine body 3 inside the outer shell 2 to adjust its position until the generator blades 4 at the output shaft end of the wind turbine body 3 are adjusted to face the wind direction, thereby achieving the purpose of easy adjustment.

[0043] like Figure 3 As shown, a guide groove 17 is annularly opened at the bottom middle part of the outer shell 2. A damper 18 is provided at each of the four corners of the top of the transmission frame 902. A pulley 19 is provided at the output shaft end of each of the four dampers 18. The four pulleys 19 are movably connected to the inside of the guide groove 17. Limiting plates 20 are fixedly installed on both sides of the bottom end of the pulleys 19. An annular groove 21 is opened on both sides of the inner wall of the guide groove 17. The limiting plates 20 are slidably connected to the annular groove 21.

[0044] In this embodiment, when the outer casing 2 is adjusted, the dampers 18 at the four corners of the top of the transmission frame 902 will drive the pulley 19 to slide synchronously inside the guide groove 17, and can dampen and buffer the outer casing 2 while it moves, thereby protecting the transmission shaft between the driven gear 10 and the outer casing 2.

[0045] A power generation method for a new energy wind turbine that can track wind direction:

[0046] Step 1: When the airflow enters from any side of the air guide shroud 5, it will blow the air guide fan blade 602 in that direction. The air guide fan blade 602 rotates under the influence of the wind, which in turn controls the lead screw 601 on one side to rotate synchronously. After the lead screw 601 rotates, it drives the swing arm 701 to move laterally in the direction of the air guide fan blade 602 at that position. After the swing arm 701 moves, the positioning plate 702 at its other end gradually approaches the positioning sensor 703. When the positioning sensor 703 detects the positioning plate 702, it controls the reduction motor 901 to start.

[0047] Step 2: After the geared motor 901 starts, it drives the drive gear 903 at one end of the transmission frame 902 to rotate. After the drive gear 903 rotates on one side of the transmission frame 902, it will drive the driven gear 10 meshing on the other side to rotate synchronously. After the driven gear 10 rotates, it drives the top shell 2 to rotate synchronously through the transmission shaft, thereby controlling the wind turbine body 3 inside the shell 2 to adjust its position until the generator blades 4 at the output shaft end of the wind turbine body 3 are adjusted to face the wind direction.

[0048] Step 3: When the fan blade 602 at this position rotates, the transmission rod 802 installed at its end will drive the scraper 803 located outside the protective net 801 to rotate synchronously. When the scraper 803 at this position rotates, it can clean the debris covering the surface of the protective net 801, avoid clogging the protective net 801, and allow the wind to pass through the air guide shroud 5 normally.
