Description

Technical Field

[0001] The present invention relates to the technical field of micro-wind power generation devices, and specifically to a dual-axis coupled vertical-axis micro-wind power generation device. Background Art

[0002] Micro-wind power generation is a clean and renewable energy utilization method, which can reduce the dependence on traditional energy, lower energy consumption and environmental pollution. The advantage of micro-wind power generation is that it can use any wind speed. As long as the wind speed is above 2 m / s, power can be generated, thereby reducing the requirements for the installation site of the wind power generation device. It can be widely applied to urban and rural open spaces, building rooftops, both sides of roads, etc., and is suitable for large-scale distributed installation and application.

[0003] Due to structural limitations, the existing vertical-axis micro-wind power generation devices inevitably have problems such as wind refraction, leeward counteraction, non-concentrated wind force, and insufficient kinetic energy, resulting in a wind energy utilization coefficient generally between 30% and 40%, which greatly limits the popularization and application of micro-wind power generation technology.

[0004] Therefore, it has become the common wish of the majority of wind power engineering researchers and engineering and technical personnel to research and develop a new and efficient micro-wind power generation device. Summary of the Invention

[0005] In order to overcome the defects in the prior art, the purpose of the present invention is to provide a dual-axis coupled vertical-axis micro-wind power generation device to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the present invention provides a dual-axis coupled vertical-axis micro-wind power generation device, including a magnetic levitation generator, a power distribution cabinet and an energy storage cabinet. At the upper end of the transmission shaft of the levitation generator, there is a wind guide cylinder for driving its rotation. Inside the wind guide cylinder, there is an energy conversion part for guiding the wind beam to converge into two strands as the kinetic energy for driving the transmission shaft. The wind guide cylinder has a box structure with openings at the front and back, and its interior is embedded between the upper and lower parts in a wind guide seat. The cross-section of the wind guide seat is a pointed ellipse and points in the front and back directions of the wind guide cylinder. On both sides outside the middle of the wind guide seat, there are symmetrically arranged air-conditioning seats. The front end of the air-conditioning seat is rotatably connected with an air-conditioning door. The air-conditioning door is in the shape of an arc plate, and its front end is in clamping fit with the inner wall of the front end of the wind guide cylinder. A hyperbolic air inlet duct is formed between the two sides of the front half of the wind guide seat and the two air-conditioning doors.

[0007] The energy conversion part includes two wind wheels embedded between the side of the middle part of the air guide base and the two air flow adjustment bases, and coupling gears sleeved on the top ends of the central axes of the two wind wheels and meshing with each other; a number of blades are arranged at equal intervals in a ring shape on the side wall of the central axis of the wind wheel, and the blades are in the shape of arc plates. The two wind wheels are arranged symmetrically with respect to the central axis of the air guide base, and the wind wheels are located at the inner port of the air inlet duct. The transverse width of the air inlet duct is smaller than the radius of the wind wheel; the air flow entering the air inlet duct is accelerated and impacts the concave arc surface of the wind wheel blade to do work, so that the air flow does not refract and is disturbed by the backwind impact on the convex arc surface of the wind wheel blade. The energy conversion part superimposes the work done by the two wind wheels, drives a magnetic levitation generator to work, and outputs electricity to the power distribution cabinet for energy storage.

[0008] As a further improvement of this technical solution, the width of the inner port of the air inlet duct is 1 / 10 - 1 / 15 of the perimeter of the wind wheel blade's swept cross-section.

[0009] As a further improvement of this technical solution, the diameter of the central axis of the wind wheel is 1 / 6 - 1 / 8 of the diameter of the wind wheel blade's swept cross-section, and the number of blades is 8 - 10.

[0010] As a further improvement of this technical solution, a circular ring-shaped guide rail, a motor for driving the circular ring-shaped guide rail to rotate, and a wind direction monitoring sensor are assembled at the bottom of the air guide cylinder. When the wind direction changes, the motor is started by detecting the wind direction through the wind direction monitoring sensor to drive the air guide cylinder to rotate, so as to adjust the front port of the air guide cylinder to face the oncoming wind direction.

[0011] As a further improvement of this technical solution, clamping grooves are opened vertically at the front end of the air flow adjustment base, rotating blocks protrude vertically at the rear end of the air flow adjustment door, the rotating blocks are clamped with the clamping grooves and inserted through a transmission shaft, and an electric motor is coaxially connected to the bottom end of the transmission shaft.

[0012] As a further improvement of this technical solution, an exhaust duct is formed between the air flow adjustment base and the inner side wall of the air guide cylinder. An exhaust port is formed between the rear end of the exhaust duct and the rear end of the air guide cylinder, and the width of the exhaust port is smaller than the distance width between the front end of the exhaust duct and the inner side wall of the air guide cylinder; when the operating wind speed is higher than the rated maximum wind speed, the air flow adjustment door is driven to leave the inner side wall of the air guide cylinder by driving the electric motor, so that the air flow is discharged from the exhaust duct for air leakage.

[0013] As a further improvement of this technical solution, air guide grooves are symmetrically opened in the middle of both sides of the air guide base, and air flow adjustment grooves are opened at the front end of the air flow adjustment base and facing the side wall of the air guide base. The cross-sections of the air guide grooves and the air flow adjustment grooves are in the shape of arc surfaces and have the same center and the same radius. The relatively arranged air guide grooves and air flow adjustment grooves are adapted to be sleeved with a wind wheel.

[0014] As a further improvement of the technical solution, air guiding slopes are provided on the upper and lower surfaces of the front end of the air guiding cylinder. The inner edges of the air guiding slopes extend to the front end of the air regulating base. Limiting grooves are formed on the inner side walls of the front end of the air guiding cylinder, and the front end of the air regulating door is clamped and matched with the limiting grooves.

[0015] As a further improvement of the technical solution, the upper and lower ends of the wind wheel are installed on magnetic suspension bearings. Through holes are symmetrically formed on the upper and lower surfaces of the air guiding cylinder, and the through holes are sleeved and matched with the outer shells of the magnetic suspension bearings.

[0016] As a further improvement of the technical solution, there are two magnetic suspension generators, and the two transmission shafts are correspondingly coaxially connected to the central shafts of the two wind wheels.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. For the double-shaft coupled vertical-axis micro-wind power generation device, by adopting the air guiding cylinder with double-channel symmetric coupled air inlet, the vibration of the device caused by the component force in the non-power direction is reduced, and the operation stability of the device is improved; the two air inlet ducts converge into two air beams and impact on the concave arc surface of the blades of the wind wheel, so that the refraction of the convex surface of the wind wheel blades to the wind force and the backwind impact are reduced to zero, effectively improving the wind energy utilization coefficient.

[0019] 2. For the double-shaft coupled vertical-axis micro-wind power generation device, by providing the air regulating door on one side of the air inlet duct, when the operating wind speed is higher than the rated maximum wind speed, the air regulating door is driven by the driving electric motor to leave the inner side wall of the air guiding cylinder, and then the air beam is discharged from the exhaust duct for air release, protecting the safe operation of the device.

[0020] 3. For the double-shaft coupled vertical-axis micro-wind power generation device, a circular ring-shaped guide rail, a motor for driving the circular ring-shaped guide rail to rotate and a wind direction monitoring sensor are assembled at the bottom of the air guiding cylinder; when the wind direction changes, the wind direction monitoring sensor detects the wind direction and starts the motor to drive the air guiding cylinder to rotate, thereby adjusting the front port of the air guiding cylinder to face the oncoming wind direction, ensuring full-load facing the wind at any time.

[0037] Please refer to Figures 1-9 As shown, the present invention provides a dual-axis coupled vertical-axis micro-wind power generation device, including a magnetic levitation generator, a power distribution cabinet, and an energy storage cabinet. At the upper end of the transmission shaft of the magnetic levitation generator, there is a wind guide cylinder 100 for driving its rotation. Inside the wind guide cylinder 100, there is an energy conversion part 200 for guiding the wind beam to converge into two strands as the kinetic energy for driving the transmission shaft; at the bottom of the wind guide cylinder 100, a circular ring-shaped guide rail, a motor for driving the circular ring-shaped guide rail to rotate, and a wind direction monitoring sensor are assembled. An upright pipe sleeved with the circular ring-shaped guide rail is installed on the power distribution cabinet. The output end of the motor is coaxially connected with a gear, and a gear ring meshing with the gear is sleeved on the outer wall of the circular ring-shaped guide rail; when the incoming wind direction changes, the wind direction monitoring sensor detects the wind direction and starts the motor to drive the wind guide cylinder 100 to rotate, so as to adjust the front port of the wind guide cylinder 100 to face the incoming wind direction, ensuring full-load facing the wind at any time.

[0038] Specifically, the wind guide cylinder 100 has a box structure with openings at the front and rear, and its interior is embedded between the upper and lower parts of the wind guide seat 110. The cross-section of the wind guide seat 110 is a pointed ellipse and points in the front and rear directions of the wind guide cylinder 100, thus dividing the interior of the wind guide cylinder 100 into two parts; on both sides outside the middle of the wind guide seat 110, there are symmetrically arranged air-conditioning seats 120, thus dividing the interior of the wind guide cylinder 100 into four parts; the front end of the air-conditioning seat 120 is rotatably connected with an air-conditioning door 130. The air-conditioning door 130 is in the shape of an arc plate, and its front end is in clamping fit with the inner wall of the front end of the wind guide cylinder 100; the convex arc surface of the air-conditioning door 130 is opposite to the convex arc surface of the wind guide seat 110. Between the two sides of the front half of the wind guide seat 110 and the two air-conditioning doors 130, there is a hyperbolic air inlet duct 150 for smoothly guiding the wind beam into the space between the wind guide seat 110 and the two air-conditioning seats 120;

[0039] Its windward surface is designed with two hyperbolic Venturi structure air inlet ducts 150. Inside the air inlet duct 150, the Bernoulli equation of fluid mechanics is followed. After the cross-section is reduced several times and the wind speed is increased several times, it enters the concave surface of the blades of the wind wheel 210, pushing the wind wheel 210 to do external work;

[0040] The energy conversion part 200 includes two wind wheels 210 embedded between the middle sides of the air guide base 110 and two air adjustment bases 120, and a coupling gear 230 sleeved on the top ends of the central axes of the two wind wheels 210 and meshing with each other; a plurality of blades are arranged at equal intervals in a ring shape on the side wall of the central axis of the wind wheel 210, and the blades are in an arc plate structure. The two wind wheels 210 are arranged in mirror symmetry about the central axis of the air guide base 110, and the wind wheels 210 are located at the inner port of the air inlet duct 150. The transverse width of the air inlet duct 150 is smaller than the radius dimension of the wind wheel 210. Due to the existence of the venturi effect, the incoming air flow velocity entering the wind wheel 210 is increased, so that the work capacity is greatly increased; the air beam entering the air inlet duct 150 is accelerated and impacts the concave arc surface of the blade of the wind wheel 210 to do work, so that the air beam does not refract and backwind against the convex arc surface of the blade of the wind wheel 210, reducing the refraction and backwind of the convex surface of the blade of the wind wheel 210 against the wind force to zero, effectively improving the wind energy utilization coefficient; the energy conversion part 200 superimposes the work done by the two wind wheels 210, drives a magnetic levitation generator to work, and outputs electricity to the power distribution cabinet for energy storage.

[0041] Further, the width of the inner port of the air inlet duct 150 is 1 / 10 - 1 / 15 of the perimeter of the swept area of the blade of the wind wheel 210; the swept area is the projected area of the blade of the wind wheel 210 on the plane perpendicular to the rotation axis when the wind wheel 210 rotates. Due to the existence of the venturi effect, the incoming air flow velocity entering the wind wheel 210 is increased, so that the work capacity is greatly increased;

[0042] The diameter of the central axis of the wind wheel 210 is 1 / 6 - 1 / 8 of the diameter of the swept area of its blade, and the number of blades is 8 - 10; the volume and weight of the wind wheel 210 are made to be 1 / 3 - 1 / 4 of the volume and weight of the traditional vertical axis wind turbine, thus greatly reducing the manufacturing difficulty and manufacturing cost.

[0043] Further, clamping grooves 122 are opened up and down at the front end of the air adjustment base 120, rotating blocks 131 protrude up and down at the rear end of the air adjustment door 130, the rotating blocks 131 are clamped with the clamping grooves 122 and are inserted through a transmission shaft, and an electric motor is coaxially connected to the bottom end of the transmission shaft;

[0044] An exhaust duct 140 is formed between the air adjustment base 120 and the inner side wall of the air guide cylinder 100. An exhaust port 141 is formed between the rear end of the exhaust duct 140 and the rear end of the air guide cylinder 100, and the width of the exhaust port 141 is smaller than the spacing width between the front end of the exhaust duct 140 and the inner side wall of the air guide cylinder 100; when the operating wind speed is higher than the rated maximum wind speed, the air adjustment door 130 is driven to leave the inner side wall of the air guide cylinder 100 by driving the electric motor, so that the air beam is discharged from the exhaust duct 140 for air release to protect the safe operation of the device.

[0045] Furthermore, air guiding grooves 111 are symmetrically formed in the middle parts on both sides of the air guiding base 110. An air adjusting groove 121 is formed at the front end of the air adjusting base 120 and faces the side wall of the air guiding base 110. The cross sections of the air guiding groove 111 and the air adjusting groove 121 are arc surfaces with the same center and the same radius. The relatively arranged air guiding groove 111 and air adjusting groove 121 are sleeved and adapted to a wind wheel 210, preventing the air beam from flowing away through the gap, so that all of them impact the concave surface of the blades of the wind wheel 210 to do work.

[0046] Furthermore, air guiding slopes 101 are arranged on the upper and lower surfaces of the front end of the air guiding cylinder 100. The inner edge of the air guiding slope 101 extends to the front end of the air adjusting base 120, enabling the air beam entering the air guiding cylinder 100 to flow smoothly and converge to impact the wind wheel 210; limiting grooves 102 are formed on the inner side walls of the front end of the air guiding cylinder 100, and the front end of the air adjusting door 130 is clamped and matched with the limiting grooves 102, thereby increasing the strength of the air adjusting door 130 to resist the air beam.

[0047] It should be noted that the upper and lower ends of the wind wheel 210 are installed on the magnetic suspension bearings 220. Through holes 103 are symmetrically formed on the upper and lower surfaces of the air guiding cylinder 100, and the through holes 103 are sleeved and matched with the outer shells of the magnetic suspension bearings 220; there are two magnetic suspension generators, and the two transmission shafts are coaxially connected corresponding to the central axes of the two wind wheels 210, and then the power output is collected to the power distribution cabinet; the frictional resistance for the rotation of the wind wheel 210 is reduced to the lowest; in order to output electric power smoothly, an energy storage cabinet is designed in a supporting manner with the power distribution cabinet, so as to store the excess electric power generated at a higher wind speed and make up for the insufficient electric power generated at a lower wind speed.

[0048] The working principle of the double-shaft coupled vertical-axis micro-wind power generation device of the present invention is that when the air beam blows to the front end of the air guiding cylinder 100, it converges into two air beams through the two air inlet ducts 150 and impacts the concave arc surfaces of the blades of the wind wheel 210, causing the two wind wheels 210 to rotate in the reverse direction to do work. Due to the existence of the venturi effect, the air inlet flow velocity entering the wind wheel 210 is increased through the guidance of the air inlet ducts 150, thereby greatly increasing the work capacity; the air beam entering the air inlet ducts 150 is accelerated and impacts the concave arc surface of the blades of the wind wheel 210 to do work, so that the air beam does not refract and is not disturbed by the backwind impact on the convex arc surface of the blades of the wind wheel 210, reducing the refraction and backwind impact of the convex surface of the blades of the wind wheel 210 on the wind force to zero, effectively improving the wind energy utilization coefficient; the energy conversion part 200 superimposes the work done by the two wind wheels 210, drives a magnetic suspension generator to work, and outputs electric power to the power distribution cabinet for energy storage;

[0049] When the operating wind speed is higher than the rated maximum wind speed, the air adjusting door 130 is driven by the driving electric motor to leave the inner side wall of the air guiding cylinder 100, and the air beam is discharged from the air exhaust duct 140 for air release, protecting the safe operation of the device.

[0050] It should be noted that the above embodiments are only for explaining the technical concept and features of the present invention, and the purpose is to enable those who are familiar with this technology to understand the content of the present invention and implement it accordingly, and it cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit and essence of the present invention should be covered within the protection scope of the present invention.
