Description

Technical Field

[0001] This utility model relates to the field of wind power generation, and in particular to a track moving mechanism with side rollers. Background Technology

[0002] Wind energy, as a renewable and green energy source, has been widely used globally in recent years. Vertical axis wind power generation equipment, due to its strong adaptability to wind direction, low noise, and ease of installation, has gradually become an important choice for small-scale and distributed wind power systems. Among them, the guide rail type vertical axis wind power generation device, as an emerging structural form, uses a ring guide rail combined with a track moving mechanism, enabling wind energy collection and conversion to have strong continuity and structural flexibility, and possesses considerable application potential.

[0003] For example, Chinese patent CN202422406500.7 discloses a guide rail type vertical axis wind power generation device, which uses multiple track moving mechanisms to move along a circular track, driving the lift blades to rotate, and connecting to the drive shaft through traction ropes to realize wind energy conversion. This structure utilizes the cooperation between the guide rail and the track moving mechanism to achieve circular motion, and uses rotating components, anti-tipping mechanisms, etc. to stabilize the blades and allow them to rotate with the wind, ultimately driving the generator to generate electricity.

[0004] However, existing devices of this type still have certain problems in actual operation. For example, there is sliding friction contact between the track moving mechanism and the guide rail, and there is a lack of structures that can reduce the sliding friction. When the wind force is strong, the track moving mechanism is prone to horizontal displacement, causing the rollers to stick tightly to the inner wall of the guide rail. This results in a large sliding friction between the rollers and the guide rail, which affects the normal operation of the moving mechanism, reduces wind energy conversion efficiency, and increases wind power loss. Utility Model Content

[0005] The purpose of this invention is to provide a track moving mechanism with side rollers, which can reduce the friction between the track moving mechanism rollers and the wind turbine guide rail, and improve the utilization rate of wind power.

[0006] This utility model is achieved through the following technical solution:

[0007] A track moving mechanism with side rollers includes a track moving vehicle applied to a wind turbine guide rail, wherein the track moving vehicle is connected to lifting blades for driving the track moving vehicle.

[0008] The wind turbine guide rail includes two horizontal rail plates spaced apart vertically and a vertical plate connected between the two horizontal rail plates.

[0009] The track-moving vehicle is equipped with an axle, and main rollers are installed on both sides of the axle. The main rollers are located between two horizontal rail plates of the wind turbine guide rail and rotate in the direction of extension of the wind turbine guide rail. Both ends of the axle extend through the main rollers, and side rollers are installed at the ends of the axle. The side rollers are in contact with the inner wall of the vertical plate of the wind turbine guide rail, and the side rollers can rotate on the inner wall of the vertical plate of the wind turbine guide rail as the track-moving vehicle moves.

[0010] Compared with previous technologies, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model adds a side roller to the side of the main roller, so that the side roller can roll and contact the inner wall of the wind power guide rail as the track moving vehicle moves. This can effectively prevent the defect of excessive sliding friction between the main roller and the wind power guide rail, significantly reduce the energy loss of wind power, and improve the conversion efficiency of wind energy to electrical energy.

[0012] 2. With the addition of the side roller structure, the wind turbine guide rail and track moving vehicle have better anti-deviation ability, and can maintain stable operation under varying wind directions and unstable wind speeds, thus improving the long-term stability and reliability of the equipment.

[0013] 3. This utility model can also significantly reduce mechanical wear caused by friction, reduce maintenance frequency, and extend the service life of the rail-mounted vehicle. Attached Figure Description

[0017] Labeling explanation: 1 shaft, 11 main roller, 111 auxiliary roller, 12 side roller, 13 U-shaped frame, 14 brake disc, 2 wind turbine guide rail. Detailed Implementation

[0018] The present invention will now be described in detail with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description:

[0019] A track moving mechanism with side rollers includes a track moving vehicle applied to a wind turbine guide rail 2, wherein the track moving vehicle is connected to lifting blades for driving the track moving vehicle.

[0020] The wind power guide rail 2 includes two horizontal rail plates spaced apart vertically and a vertical plate connected between the two horizontal rail plates.

[0021] The track moving vehicle is equipped with a shaft 1, and main rollers 11 are installed on both sides of the shaft 1. The main rollers 11 are located between the two horizontal rail plates of the wind power guide rail 2 and rotate in the extension direction of the wind power guide rail 2. Both ends of the shaft 1 extend through the main rollers 11, and side rollers 12 are installed at the ends of the shaft 1. The side rollers 12 are in contact with the inner side wall of the vertical plate of the wind power guide rail 2, and the side rollers 12 can rotate on the inner side wall of the vertical plate of the wind power guide rail 2 as the track moving vehicle moves.

[0022] like Figure 1 The first embodiment of this utility model is shown below:

[0023] The shaft 1 is a fixed shaft, and U-shaped frames 13 are installed at both ends of the fixed shaft. The openings of the U-shaped frames 13 are all facing away from the side of the track moving vehicle.

[0024] The two ends of the U-shaped frame 13 are respectively rotatably connected to a main roller 11 and an auxiliary roller 111; the main roller 11 and the auxiliary roller 111 are spaced apart vertically and clamp a horizontal rail plate of the wind power guide rail 2; wherein, the U-shaped frame 13 passes through the main roller 11 and a side roller 12 is installed at the outer end of the U-shaped frame 13.

[0025] It should be noted that the length of the axle can be slightly less than the distance between the two wind turbine guide rails 2, so that the entire track moving vehicle and the axle have a certain horizontal movement clearance. When the side rollers 12 are attached to the inner wall of the wind turbine guide rail 2, they can rotate on the inner wall of the wind turbine guide rail 2 as the track moving vehicle moves to reduce friction. The length of the axle can also be set so that both side rollers 12 are attached to the inner wall of the corresponding wind turbine guide rail 2.

[0026] like Figure 2 and Figure 3 The following are all second embodiments of this utility model:

[0027] The shaft 1 is a rotating shaft, and main rollers 11 are fixedly connected to both ends of the rotating shaft;

[0028] The side roller 12 is a universal roller.

[0029] Furthermore, a brake disc 14 is also mounted on the shaft.

[0030] It should be noted that, Figure 2 and Figure 3 The wind turbine guide rail 2 consists of an I-beam structure and a semi-enclosed structure. The shaft structure is an equivalent replacement for the axle structure, in which the main roller 11 is fixedly connected to the shaft. Furthermore, the brake disc 14 is an existing structure; when necessary, the movement of the track-moving vehicle can be stopped by pulling the brake disc 14.

[0031] In summary, this invention adds a side roller structure as a driven wheel to the side of the main roller, allowing the side roller to roll and contact the inner wall of the wind turbine guide rail as the track-moving vehicle moves. This effectively prevents excessive friction between the main roller and the wind turbine guide rail, significantly reducing wind energy loss and improving the conversion efficiency of wind energy to electrical energy. With the addition of the side roller structure, the wind turbine guide rail and track-moving vehicle have better anti-deviation capabilities, maintaining stable operation under varying wind directions and unstable wind speeds, thus improving the long-term stability and reliability of the equipment. It also significantly reduces mechanical wear caused by friction, lowers maintenance frequency, and extends the service life of the track-moving vehicle.

[0032] Although this utility model has been illustrated and described using specific embodiments and alternative methods, it should be understood that various changes and modifications are permitted as long as they do not depart from the spirit and scope of this utility model. Therefore, it should be understood that this utility model is not limited in any sense except by the appended claims and their equivalents.
