Description

Technical Field

[0001] This utility model belongs to the field of wind power generation technology, and specifically relates to a vertical axis lightweight blade omnidirectional micro wind power generation device. Background Art

[0002] A wind turbine is a renewable energy power device that converts the kinetic energy of wind into mechanical energy, and then the mechanical energy into electrical energy by a generator. Currently, commonly used wind turbines are divided into two types: horizontal axis wind turbines and vertical axis wind turbines. Horizontal axis wind turbines are usually large generators and have high requirements for the location of use, while vertical axis wind turbines are usually small or medium-sized, have a wider range of applications, and are more convenient to use.

[0003] After searching, the prior art publication number CN 118030370 was found. A single-blade wind turbine for a vertical axis micro wind turbine includes a wind turbine mounting base on which a vertical axis wind turbine is mounted. The vertical axis wind turbine includes multiple lightweight blades arranged in a ring and spaced apart. At least one set of connecting beams is fixedly mounted on the inner surface of each lightweight blade. The other end of the connecting beams is fixedly mounted on the wind turbine mounting base. A wind-concentrating blade is arranged on the connecting beams corresponding to each lightweight blade. The leading edge of the wind-concentrating blade abuts against the back of the corresponding lightweight blade, forming a wind-concentrating bucket between them. This invention can be installed on a vertical axis wind turbine, and the wind turbine has low wind speed requirements, can start in a light wind environment, and can also work normally in a strong wind environment. In the above solution, the leading edge of the wind-concentrating blade abuts against the back of the corresponding lightweight blade, forming a wind-concentrating bucket between them. The wind-concentrating bucket obstructs the wind and makes it rotate. Therefore, the wind-concentrating bucket needs to be opposite to the wind direction so that the wind impacts the wind-concentrating bucket to maximize the utilization of wind power. If the wind direction is in the same direction as the wind-concentrating bucket, no wind resistance will be formed, and it will not be able to rotate.

[0004] Further searching revealed an adaptive micro-wind power generation system and its control method published in CN 118601794 A, which provides a micro-wind control power generation scheme.

[0005] The prior art publication number CN 116677561 A discloses a vertical axis wind turbine, which discloses a vertical wind power generation scheme that can automatically adjust the rotation speed according to the rotation speed of the rotating shaft.

[0006] Based on the technical problems encountered in the above-mentioned searched technical solutions, this utility model provides a vertical axis lightweight blade omnidirectional micro wind power generation device. Summary of the Invention

[0007] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a vertical axis lightweight blade omnidirectional micro wind power generation device. Through the vertical and dense array of blades, it can generate force to drive the generator set to operate and generate electricity regardless of wind direction.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] A vertical-axis lightweight blade omnidirectional micro-wind power generation device includes a tower, a column, a grid frame, blades, a generator set, a mounting base, and a support mechanism. The grid frame is mounted on the column, and several sets of blades are fixed to the grid frame. The tower is hollow and has internal ladders for climbing. The generator set is fixed inside the tower via a mounting frame. The bottom of the column is connected to the mounting base, which is rotatably connected to the support mechanism. The support mechanism is located at the top of the tower, and one end of the mounting base is connected to the generator set via a coupling. Micro-winds blow the blades, causing the grid frame, column, and mounting base to rotate, which in turn drives the generator set to rotate and generate electricity.

[0010] The bearing mechanism includes a fixed seat, a support seat, and a second bearing; the fixed seat is fixedly connected to the inner wall of the tower; the support seat is sleeved on the fixed seat and fixed to it at the bottom by a connecting plate and bolts; the outer ring of the second bearing is fixed to the support seat by bolts, and the bottom end of the support seat is provided with an installation groove; the mounting seat is fixedly connected to the inner ring of the second bearing by bolts; the mounting seat is provided with a fixed shaft, and the end of the fixed shaft is provided with a first coupling, which is connected to the generator set.

[0011] Furthermore, the grid structure includes several sets of ring pipes distributed at equal intervals, and several sets of horizontal pipes are provided on the ring pipes. The two ends of the horizontal pipes are connected to the columns and the ring pipes respectively. Several vertical pipes are provided at equal intervals between adjacent horizontal pipes for fixing and installing blades. The ring pipes, vertical pipes and horizontal pipes cooperate with each other to form a dense grid.

[0012] Furthermore, the included angle between the blade and the transverse tube is 18°-25°.

[0013] Furthermore, the optimal angle between the blade and the horizontal tube is 20°.

[0014] Furthermore, one end of the fixed shaft is provided with a fixedly connected limiting flange and a sleeved first bearing and retaining ring. The first bearing is located in the mounting groove, and the retaining ring is located below the first bearing. The retaining ring is fixed to the fixed shaft by bolts and cooperates with the limiting flange to fix the first bearing.

[0015] Furthermore, a fixing post is provided at the top of the column; a first tie rod is provided on the fixing post, and one end of the first tie rod is connected to a ring tube for auxiliary fixation.

[0016] Furthermore, a fixing rod is provided between the horizontal tubes for fixed connection, and a second tie rod is provided on the fixing rod. One end of the second tie rod is connected to the column for auxiliary fixing to make the grid frame firmly fixed.

[0017] Furthermore, the generator set is equipped with a second coupling and a motor connected to each other at the bottom to assist in starting the generator set; the motor drives the second coupling to rotate, thereby driving the generator set to start and run.

[0018] Furthermore, the generator set is equipped with a braking system and brake pads at its bottom; the brake pads are fixed on a rotating shaft at the bottom of the generator set; the braking system is fixed on a mounting bracket used to support and install the generator set; the speed of the generator set is controlled by the braking system in conjunction with the brake pads, so that it runs at a constant speed, and it can be completely locked during maintenance to ensure safety. The braking system and brake pads are based on the existing disc brake technology, which will not be elaborated on here.

[0019] Furthermore, the tower is equipped with a first operating platform, a second operating platform, and several door openings for easy maintenance; the bottom of the tower is equipped with a pre-embedded base.

[0020] Furthermore, the ring pipes, risers, horizontal pipes, and blades are made of carbon fiber, while the columns are made of fiberglass.

[0021] The advantages of this utility model compared with the prior art are as follows:

[0022] 1) This design includes a grid frame with several evenly fixed blades arranged vertically. This allows the blades to generate thrust from both sides without any restriction on their windward direction, enabling them to withstand wind from various wind directions and drive the column and mounting base to rotate, thus powering the generator set. In contrast, the wind-gathering bucket used in the comparative document requires the opening of the bucket to face the wind in order to generate thrust. The other end of the bucket is narrow and creates shear force on the wind, causing it to disperse and fail to effectively block the wind. Therefore, this design has certain requirements regarding wind direction and a narrower range of applications. Furthermore, this design includes an auxiliary motor below the generator set to assist in starting the generator set, providing power assistance during the transition from a stationary state to operation. Additionally, a brake cylinder and brake pads are located below the generator set. The use of disc brake technology effectively controls the operating speed of the generator set, preventing overload and increased component damage due to excessive speed.

[0023] 2) The fixed shaft is equipped with a first bearing that works with the second bearing to improve the smoothness of the fixed shaft's rotation, thereby reducing the wind power loss rate when driving the fixed shaft to rotate;

[0024] 3) The space frame is equipped with a first tie rod and a second tie rod that work together to effectively fix the space frame. Furthermore, the space frame is formed by horizontal tubes, vertical tubes, ring tubes and fixed rods arranged vertically to form a dense grid. Combined with the blades fixed on the vertical tubes, the windward area of ​​the blades can be effectively increased, and the breeze can be effectively captured to maximize the utilization efficiency of wind power.

This, in turn, drives the generator set 4 to generate electricity through the first coupling 41. When maintenance is required, the brake system 44 can be used in conjunction with the brake pads 45 to lock the brakes and prevent the generator set 4 from running. When starting, the motor 43 drives the second coupling 42 and the generator set 4 to generate electricity. Maintenance is facilitated by climbing the ladder inside the tower 1, along with the doorway 14, the first operating platform 12, and the second operating platform 13.
