Description
Technical Field
[0001] This invention relates to the field of wind power generation equipment technology, and is applicable to various types of exhaust duct waste heat auxiliary power generation and outdoor pure natural wind drum-type wind power generation equipment. Background Technology
[0002] Existing drum-type wind turbines are supported by only a single slide rail, making the outer cylinder prone to swaying in strong winds and resulting in poor stability. Traditional structures have too many limiting features, which competitors can easily circumvent by simply modifying the slide rail, blades, motor, and bracket installation positions. Conventional blades extend to the top cover, which can easily cause backflow of air and obstruct internal ventilation. Traditional drum-type wind turbines can only be driven by a single natural wind or a single exhaust airflow, and cannot simultaneously couple two types of wind energy, resulting in low wind energy utilization. Most of these devices are only compatible with a single vertical chimney, limiting their applicability to a narrow range of scenarios. Summary of the Invention
[0003] Technical problems to be solved The existing device has insufficient support stability, which can be easily avoided by adjusting the position of the slide, blades, generator, and transmission support; unreasonable fan blade layout can easily cause backflow and obstruction of exhaust; it cannot utilize both internal exhaust and external natural wind energy at the same time, resulting in low wind energy utilization; it is only suitable for a limited range of scenarios and cannot be compatible with various exhaust ducts and pure natural wind usage requirements.
[0004] Technical solution An axially multi-supported annular slide roller wind power generation device includes a fixed cylinder, an annular slide support assembly, an outer rotating wind collection assembly, a central support bracket, a generator, and a transmission assembly. The annular slide support assembly is arranged along the axial direction of the fixed cylinder, providing multi-point limiting sliding support for the externally rotating air collection assembly; the slide structure is not limited, and two or more independent annular slides can be used, or a single axially widened annular slide can be used. The slide sliding fit structure can be any form of roller, slider, or bearing, and the manufacturer can freely customize it according to the actual working conditions. The external rotating air collection assembly is slidably mounted on the outside of the annular slide support assembly. The outer wall is provided with several air receiving blades, which are arranged between the upper slide and the lower slide. An open ventilation channel is formed above the upper slide. The central support bracket is fixedly installed inside the fixed cylinder, and the generator is fixedly installed in the middle of the central support bracket; The transmission assembly includes a transmission shaft and a connecting bracket. The transmission shaft is connected to the generator rotor. The external rotating air collection assembly is fixedly connected to the transmission shaft through the connecting bracket. The form of the connecting bracket is not limited. It can be a rigid connection structure such as a multi-spoke bracket, a single support arm, or a ring support seat. The connecting bracket can be installed at any axial position of the transmission shaft. When the wind-driven blades rotate under the wind force, the transmission shaft rotates synchronously through the connecting bracket. The fixed cylinder can be optionally equipped with a built-in exhaust fan blade assembly. The built-in exhaust fan blade is linked to the drive shaft. Both the built-in exhaust fan blade and the wind-receiving blade can drive the drive shaft to rotate and generate electricity, either individually or together. The fixed cylinder can be installed vertically or horizontally. The structural principles of the two installation methods are basically the same. The horizontal installation is also equipped with a rain cover to prevent the horizontal airflow from flowing back inward. The wind-receiving blades can be any type of curved, rectangular, square, or axial fan; the generator type is not limited; the built-in exhaust fan blades can be set to one, two, or three stages; the connecting bracket can be set at the top, middle, or bottom of the drive shaft; a rain cover is set at the top of the cylinder, and the rain cover is suspended above the upper slide rail, with the rain cover and the upper slide rail connected throughout to form a ventilation open area; the air outlet of the cylinder is equipped with a support frame that is fixed to the drive shaft and rotates synchronously with the drive shaft. This device can be configured with a built-in exhaust fan blade, a separate external wind-receiving fan blade, or both simultaneously. Even if the built-in exhaust fan blade is removed and the power generation is completed solely by driving the transmission shaft with the external wind-receiving fan blade, it still falls within the scope of the basic architecture of this device and is protected by this invention. As a preferred option: the annular slide support assembly uses two separate annular slides; the generator is a permanent magnet generator; the external rotating air collection assembly is an integral or separate assembly structure; the wind-receiving blades are arc-shaped blades; the built-in exhaust fan blades are arranged in 1 to 3 stages; the connecting bracket is located at the top of the drive shaft; a rain cover is installed on the top of the cylinder; and the air outlet is equipped with a rotating support frame. Explanation of the core innovative mechanism of this invention: The wind blades are confined between the upper and lower slide tracks, with the upper part open, which solves the problem of backflow of external wind and obstruction of internal ventilation. The connecting bracket is not limited to the axial position of the drive shaft or the shape of the bracket, preventing competitors from circumventing the patent simply by moving the bracket up and down or changing the bracket style. The inner and outer fan blades share the same drive shaft, and at the same time recover the waste heat of the internal exhaust and natural wind energy, which greatly improves the wind energy utilization rate. Axial multi-support slide rails combined with various sliding fit structures solve the problem of outer cylinder swaying and displacement under strong winds; The rain cover can be installed vertically or horizontally, serving the dual purpose of preventing rain and blocking crosswinds. The core of this device's power generation relies on the architecture of the outer annular slide and the external fan blade's linkage drive shaft, and the power generation function does not depend on the protective structure on the top of the cylinder. The upper end of the cylinder can be equipped with a rain cover for rain and backflow prevention; alternatively, an integrated closed sealing plate can be used to directly seal the upper edge of the cylinder, leaving only the drive shaft to pass through. Both top structures are compatible with the core power generation architecture of this device and are both within the scope of protection of this patent.
[0005] Beneficial effects All core components of this invention adopt a top-level design, without imposing rigid limitations on the installation position of the connecting bracket, the number of slides, the shape of the blades, or the type of generator. This allows it to adapt to various structural variations and effectively avoids the problem that others can circumvent the technical solution of this device by simply modifying local structures. The wind-receiving blades are only arranged in the upper and lower slide sections, with the upper part completely open to avoid backflow of external wind and to ensure that the airflow inside the tube is discharged outward. The axial multi-point sliding support structure, combined with various sliding cooperation forms such as rollers, sliders, and bearings, makes the outer cylinder less prone to shifting and swaying in strong winds, resulting in excellent overall structural stability. The dual wind power drive mode can generate electricity by relying on the exhaust airflow inside the equipment, or it can make full use of outdoor natural wind energy to fully recover and utilize wind energy resources. It is compatible with both vertical and horizontal installation methods, and its structural principle is universal. It can be adapted to various ventilation scenarios such as server rooms, hotel central air conditioning exhaust, thermal chimneys, and fresh air ducts in large shopping malls. It can also be used alone in the open to generate electricity from pure natural wind. One set of structures does not need to be modified, reducing the manufacturer's customization costs. The rain cover serves the dual purpose of protecting against rain and blocking backdrafts. The rotating support frame of the air outlet further enhances the stability of the rotating structure and extends its outdoor service life. The top structure of the cylinder is not limited; it can be either open-air or fully enclosed with rain protection. Changing only the top protective structure cannot avoid the core slide-driven power generation architecture of this patent. Attached Figure Description

Detailed Implementation
[0007] Example 1: Vertical Double-Slide Dual-Power Foundation Scheme The fixed cylinder has two annular slide rail support assemblies on its outer wall. The outer rotating air collecting assembly is slidably mounted on the outside of the two slide rails. Arc-shaped wind-receiving blades are evenly arranged on the outer wall, and all wind-receiving blades are located between the upper and lower slide rails. There are no blades obstructing the upper slide rail, forming an open ventilation section. A central support bracket is set at the center of the cylinder, and a permanent magnet generator is installed in the middle of the bracket. The transmission assembly includes a drive shaft and a multi-spoke connecting bracket. The connecting bracket is mounted on the top of the drive shaft, rigidly fixing the outer rotating air collecting assembly to the drive shaft. The fixed cylinder has a two-stage built-in exhaust fan assembly inside. The built-in exhaust fan is linked to the drive shaft. The internal exhaust airflow and external natural wind can jointly drive the outer rotating air collecting assembly to rotate, which drives the generator to generate electricity via the drive shaft. The air outlet of the cylinder has a support frame that is fixed to the drive shaft and rotates synchronously. A rain cover is installed on the top of the cylinder. The rain cover is suspended above the upper slide rail, with a continuous ventilation gap reserved between the two to prevent rain and backflow of external airflow. In this embodiment, the connecting bracket can also be replaced with a single support arm or a ring-shaped support base, or it can be moved down to the middle or bottom of the drive shaft for installation without changing the transmission linkage effect; the sliding structure of the slide can be any of rollers, sliders, or bearings. It is suitable for exhaust scenarios such as server rooms, shopping mall fresh air systems, and thermal chimneys. Example 2: Horizontal Piping Assembly Scheme In this embodiment, the cylinder is arranged horizontally, and the annular slide support assembly still uses two independent upper and lower slides. The external rotating air collection assembly is equipped with axial flow fan-type wind-receiving blades, which are constrained between the two slides. The transmission component connecting bracket is installed in the middle section of the transmission shaft and adopts an annular support structure. A single-stage built-in exhaust fan blade can be configured inside the cylinder, and the duct exhaust and horizontal natural wind work together to drive the equipment to generate electricity. The top of the cylinder is equipped with a rain cover, which maintains a continuous ventilation area between the rain cover and the upper slide, which can prevent strong outdoor horizontal winds from flowing back in and ensure smooth duct exhaust. The overall transmission, slide, and blade arrangement structure is completely consistent with the vertical scheme, only the cylinder placement posture is adjusted, which is an equivalent protected structure of this invention and is suitable for horizontal exhaust ducts of hotel central air conditioning. Example 3: Outdoor Power Generation Scheme Based on Pure Natural Wind Without Built-in Wind Blades In this embodiment, the cylinder is installed vertically in the open air, eliminating the built-in exhaust fan blade assembly. The entire unit has no built-in exhaust fan blades and is driven solely by natural wind power. The upper end of the cylinder is directly sealed with a closed end plate, eliminating the rain cover. The external wind-receiving blades are assembled on the outside of the cylinder using multi-stage annular slides. The external wind blades are rigidly connected to the drive shaft. Natural wind blows the external wind blades to rotate, driving the drive shaft to drive the generator to generate electricity. This is suitable for outdoor independent wind power generation scenarios.
