Description

Technical Field

[0001] This invention relates to the field of elevator equipment technology, and in particular to a wind power generation device for elevator shafts. Background Technology

[0002] To achieve resource utilization and energy conservation goals in elevator shaft space, existing technologies propose installing vertical axis wind turbine generators inside the elevator shaft. These devices fix a vertical axis wind turbine at a suitable location on the inner wall of the shaft. When the elevator car moves up and down at high speed within the shaft, it creates a directional airflow. This airflow acts on the blades of the vertical axis wind turbine, causing it to rotate and drive a connected generator. This converts mechanical energy into electrical energy, thus recovering and utilizing the kinetic energy of the air during elevator operation. The generated electricity can be used to power the elevator's auxiliary equipment or fed into the power grid, achieving energy conservation. However, during prolonged use, the wind power generation devices in elevator shafts are susceptible to dust accumulation on the blades of vertical axis wind turbines due to the environment within the elevator shaft. This continuous dust accumulation leads to two key problems: first, it increases the overall weight of the blades, altering their original center of gravity balance; second, it increases the surface roughness of the blades, disrupting their original aerodynamic shape. These two problems combined mean that the blades, driven by airflow, must overcome greater mechanical friction and air resistance, directly increasing the rotor's rotational resistance. This not only reduces the rotor's rotational efficiency and power generation but, in severe cases, can cause the rotor to stall due to excessive resistance, affecting the stable operation of the entire power generation device and even shortening its lifespan.

[0003] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0004] This invention provides an elevator shaft wind power generation device to solve the problems of dust accumulation on the vertical axis wind turbine blades of elevator shaft wind power generation devices, which increases weight and roughness, leading to increased rotational resistance, reduced efficiency, and affecting stability and lifespan.

[0005] The present invention adopts the following technical solution: an elevator shaft wind power generation device. It includes an elevator car; a power generation device mounted on the elevator car, the power generation device including a generator fixed on the elevator car, the generator having a rotating shaft, and a vertical axis wind turbine fixed on the rotating shaft; a support frame fixed on the elevator car, and an air guide shroud fixed on the support frame; a dustproof device mounted on the air guide shroud, the dustproof device being used to prevent dust from the vertical axis wind turbine and to clean it simultaneously; and a blowing device mounted on the air guide shroud, the blowing device being used to blow away the lint and other debris cleaned by the dustproof device.

[0006] Furthermore, the dustproof part includes a filter screen that is movably mounted on the inner wall of the air guide shroud near one end via a bearing, for initially filtering dust particles in the airflow within the well. The inner wall of the air guide shroud has an embedded annular groove adapted to the installation of the bearing. A fixing ring is provided at the center of the filter screen, and a support platform is fixed at one end of the rotating shaft to provide auxiliary support for the fixing ring, thus serving as a transition support.

[0007] Furthermore, a support rod is fixed to the inner wall of the air guide shroud, and two sets of opposing cleaning brushes are fixed to the support rod via a mounting plate, with the bristles of the cleaning brushes being inclined.

[0008] Furthermore, a speed reduction transmission part is provided on the inner wall of the fixed ring. The speed reduction transmission part includes an internal gear fixed on the inner wall of the fixed ring. One end of the rotating shaft passes through the support platform and the fixed ring in sequence. A large gear is fixed on one end of the rotating shaft. A dust cover is fixed on the support rod and is arranged in the same vertical line as the support platform. A small gear two that meshes with the large gear is provided on the bottom bearing of the dust cover. The large gear is three times larger than the small gear two.

[0009] Furthermore, the bottom surface of the dust cover is also provided with a small gear one that meshes with the small gear two, and the small gear one meshes with the internal gear.

[0010] Furthermore, the blowing device includes two sets of pipe clamps fixed on the support rod, and a piston cylinder horizontally parallel to the support rod is fixed between the two sets of pipe clamps. The piston cylinder is a cavity for airflow compression and storage. One end of the piston cylinder has an opening that extends outward with a step. A piston rod is movably disposed inside the piston cylinder. The piston rod has a piston end that is located inside the piston cylinder. The other end of the piston rod has a contact end fixed. A return spring is sleeved on the piston rod. One end of the return spring is connected to the contact end, and the other end is connected to the step. One end of the rotating shaft is fixed with a cam that contacts the contact end.

[0011] Furthermore, an air inlet is connected to one end of the piston cylinder, and a one-way valve is provided at the connection between the air inlet and the piston cylinder. The one-way valve is used to control the airflow to enter the piston cylinder in one direction and prevent the airflow from flowing back. One end of the piston cylinder is connected to a one-way valve, which is used to control the compressed airflow to exit the piston cylinder in one direction. One end of the one-way valve is connected to a connecting pipe. A vent pipe is fixed to the cleaning brush through a sleeve and is arranged parallel to the cleaning brush. An air nozzle is connected to the vent pipe along its straight direction. The air nozzle is slightly tilted and is set towards the bristles of the cleaning brush.

[0012] Furthermore, a connecting crossbar is fixed to the side of the contact end, and multiple sets of levers with spacing are fixed to the bottom surface of the connecting crossbar. Partial positions of the levers are inserted into the bristles of the cleaning brush.

[0013] Furthermore, a collection assembly is provided on the surface of the air guide shroud. The collection assembly includes a collection cover fixed on the surface of the air guide shroud and corresponding to the position of the collection opening. The bottom surface of the inner wall of the collection cover is through the air guide shroud. A support cover is fixed on the surface of the air guide shroud directly below the collection cover. A collection box is slidably inserted into the side of the support cover. The collection box is fixed to the support cover by fasteners.

[0014] Furthermore, a horn end is fixed to one end of the air guide shroud to enhance the rotational power of the vertical axis impeller.

[0015] The above-described at least one technical solution adopted in the embodiments of the present invention can achieve the following beneficial effects: An elevator shaft wind power generation device effectively solves the problems of reduced power generation efficiency and operational stability caused by dust accumulation on vertical axis wind turbines by integrating a power generation device, a dust prevention device, and a blowing device. The power generation device's vertical axis wind turbine, in conjunction with an air guide shroud, efficiently captures airflow within the shaft. The dust prevention device initially filters dust from the airflow using a filter screen, and continuously cleans the filter screen with a cleaning brush, reducing direct dust adhesion to the wind turbine surface. The blowing device, through airflow blowing and lever actuation, promptly removes lint and debris from the cleaning brush, ensuring the dust prevention device maintains good filtration and cleaning performance over the long term. The combined effect of these three components prevents increased weight, center of gravity imbalance, and aerodynamic damage to the wind turbine caused by dust accumulation. It significantly reduces mechanical friction and air resistance during wind turbine rotation, effectively improving wind turbine rotation efficiency and power generation, preventing operational stalls, ensuring stable operation of the power generation device, and extending its service life.

[0018] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0019] The technical solutions provided by the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0020] Reference Figures 1-3As shown, this embodiment of the invention provides an elevator shaft wind power generation device, including an elevator car 1. Multiple sets of car frame columns 11 are provided on the sides of the elevator car 1 to provide structural support for the elevator car 1, ensuring the stability and rigidity of the car during operation in the shaft. An openable car wall 12 is provided on one side of the elevator car 1 to enclose the car space, and can be opened according to maintenance or power generation needs, combining protection and ease of operation. A car top device 13 is fixed on the top surface of the elevator car 1. The car top device 13 integrates an electrical control module (not shown in the figure) to coordinate the linkage between the power generation system and the elevator operation. A sling 14 is provided on the car top device 13 to connect the elevator car 1 to the drive system at the top of the shaft to realize the lifting and lowering movement of the car. In addition, a power generation device 2 is installed on the elevator car 1. The power generation device 2 is the core component that converts the air kinetic energy generated by the elevator's rise and fall into electrical energy. It can continuously generate electricity as the elevator car 1 rises and falls. The generated energy is stored in a battery and used to supply the elevator's daily power consumption (such as car lighting, control circuits, etc.) or emergency lighting in emergencies, realizing the recycling of energy and energy saving efficiency. The power generation device 2 includes a generator 24 fixed on the elevator car 1. The generator 24 has a rotating shaft 22, and an inclined vertical shaft fan 23 is fixed on the rotating shaft 22. It achieves rotation by capturing the rising and falling airflow in the elevator shaft (especially the directional airflow formed when the elevator rises and falls at high speed) to provide mechanical energy for power generation. A support frame 21 is fixed on the elevator car 1, and an air guide hood 25 is fixed on the support frame 21. The air guide hood 25 is used to protect the vertical axis wind turbine 23, prevent debris in the shaft from hitting the wind turbine, optimize the airflow direction, and improve the wind-catching efficiency of the wind turbine. A horn end 26 is fixed at one end of the air guide hood 25. The horn-shaped flare design can gather the dispersed airflow in the shaft, further enhance the rotational power of the vertical axis wind turbine 23, and improve the power generation efficiency.

[0021] like Figure 1 and Figures 4-7As shown, a dustproof device 3 is provided at one end of the air guide shroud 25. The dustproof device 3 is used to reduce dust adhering to the vertical axis impeller 23. The dustproof device 3 includes a dustproof part provided inside the air guide shroud 25. The dustproof part includes a filter screen 32 that is movably installed on the inner wall of the air guide shroud 25 near one end via a bearing 31. It is used to initially filter dust particles in the airflow in the well channel and prevent a large amount of dust from directly contacting the vertical axis impeller 23. At the same time, an embedded annular groove (not shown in the figure) adapted to the installation of the bearing 31 is provided on the inner wall of the air guide shroud 25. A fixing ring 331 is provided at the center of the filter screen 32. At the same time, a support platform 33 is fixed at one end of the rotating shaft 22 to provide auxiliary support for the fixing ring 331, which plays a transitional support role, so that the rotation between the fixing ring 331 and the rotating shaft 22 does not interfere with each other. The fixing ring 331 is connected to the support platform 33 by a bearing. A support rod 361 is fixed to the inner wall of the air guide shroud 25. Two sets of opposing cleaning brushes 310 are fixed to the support rod 361 via a mounting plate 311. The bristles of the cleaning brushes 310 are inclined and are used to clean the dust on the surface of the filter screen 32 when it rotates, thus maintaining the filtration performance of the filter screen 32. A speed reduction transmission part is provided on the inner wall of the fixing ring 331. The speed reduction transmission part includes an internal gear 321 fixed to the inner wall of the fixing ring 331. Meanwhile, one end of the rotating shaft 22 passes through the support platform 33 and the fixing ring 331 in sequence. A large gear 34 is fixed to one end of the rotating shaft 22 as a power input gear to transmit the rotation of the rotating shaft 22 to the subsequent gears. The gear assembly also has a dust cover 36 fixed on the support rod 361, which is vertically aligned with the support platform 33. The dust cover 36 is used to shield the gear assembly and prevent dust from entering and affecting the gear meshing accuracy. At the same time, a small gear 39 that meshes with the large gear 34 is mounted on the bottom bearing of the dust cover 36. The large gear 34 is three times larger than the small gear 39, which plays a first-stage speed reduction role. The size difference between the large gear 34 and the small gear 39 achieves an initial reduction in speed. Additionally, a small gear 38 that meshes with the small gear 39 is also mounted on the bottom bearing of the dust cover 36. This small gear 38 meshes with the internal gear 321, which plays a second-stage speed reduction role and ultimately transmits power to the internal gear 321. During operation, the rotating shaft 22 drives the large gear 34 to rotate, which in turn drives the small gear 39 to rotate. The small gear 39 then drives the small gear 38 to rotate. The small gear 38 meshes with the internal gear 321, which in turn drives the filter screen 32 to rotate slowly around the bearing 31. During this process, the cleaning brush 310 on the inner wall of the wind guide shroud 25 continuously contacts the surface of the filter screen 32, brushing off the dust attached to the filter screen 32, thus achieving self-cleaning of the filter screen 32. This effectively reduces dust adhesion to the vertical axis wind turbine 23, ensuring the wind turbine's wind capture efficiency and power generation stability.

[0022] like Figures 8-11As shown, two sets of opposing blowing devices 4 are provided on the support rod 361. These blowing devices 4 are used to blow away the lint and debris cleaned by the cleaning brush 310, preventing lint from accumulating on the cleaning brush 310 and ensuring cleaning effectiveness. Each blowing device 4 includes two sets of pipe clamps 41 fixed to the support rod 361. These pipe clamps 41 are existing technology and will not be described in detail here. A piston cylinder 42, horizontally parallel to the support rod 361, is fixed between the two sets of pipe clamps 41 to ensure the piston cylinder 42 remains stable during operation. The piston cylinder 42 is an airflow compression device. The storage cavity provides a power source for blowing away lint. A step (not shown in the figure) extends outward from the opening at one end of the piston cylinder 42. A piston rod 43 is movably disposed inside the piston cylinder 42. The piston rod 43 has a piston end that is located inside the piston cylinder 42. A contact end 45 is fixed at the other end of the piston rod 43. A return spring 44 is sleeved on the piston rod 43. One end of the return spring 44 is connected to the contact end 45, and the other end is connected to the step. A cam 46 that contacts the contact end 45 is fixed at one end of the rotating shaft 22. The rotating shaft 22 drives the cam 46 to rotate. The cam 46 pushes the contact end 45 to make the piston rod 43 move into the piston cylinder 42, compressing the air in the cylinder. At this time, the return spring 44 is compressed. When the cam 46 profile leaves the contact end 45, the return spring 44 elastically returns to its original position, pushing the piston rod 43 back to its original position. A negative pressure is formed in the piston cylinder 42. This process is repeated to realize the compression and release cycle of the airflow in the piston cylinder 42.

[0023] Meanwhile, an air inlet 47 is connected to one end of the piston cylinder 42, serving as a channel for external airflow to enter the piston cylinder 42. A one-way valve is installed at the connection between the air inlet 47 and the piston cylinder 42. This one-way valve controls the airflow to enter the piston cylinder 42 in one direction, preventing backflow. A second one-way valve 48 is connected to one end of the piston cylinder 42, controlling the compressed airflow to exit the piston cylinder 42 in one direction. One end of the second one-way valve 48 is connected to a connecting pipe 49. A vent pipe 410 is fixed to the cleaning brush 310 via a sleeve 411, parallel to the cleaning brush 310. The vent pipe 410 extends along its straight line... An upward-facing air nozzle (slightly visible in the diagram) is connected to the cleaning brush 310. This nozzle is slightly angled towards the bristles of the cleaning brush 310. Simultaneously, an arc-shaped collection opening 251 for collecting lint is provided on the air guide 25 in the straight line direction corresponding to the air nozzle. This serves as a channel for lint discharge from the air guide 25, facilitating centralized cleaning. A connecting crossbar 412 is fixed to the side of the contact end 45. Multiple sets of spaced levers 413 are fixed to the bottom surface of the connecting crossbar 412. Partial positions of these levers 413 are inserted into the bristles of the cleaning brush 310. As the piston rod 43 reciprocates horizontally, it can agitate the bristles, assisting in shaking off lint and enhancing the cleaning effect. During operation, the rotating shaft 22 drives the cam 46 to rotate. The cam 46 pushes the contact end 45 to move the piston rod 43 into the piston cylinder 42, compressing the air inside the cylinder. At this time, one-way valve one is closed and one-way valve two 48 is opened. The compressed airflow is ejected from the nozzle through the connecting pipe 49 and the vent pipe 410, blowing away the lint on the cleaning brush 310. At the same time, the connecting crossbar 412 drives the lever 413 to move with the piston rod 43, shaking the brush bristles and dislodging the lint. The lint is discharged through the collection opening 251. When the cam 46 profile leaves the contact end 45, the return spring 44 pushes the piston rod 43 back to its original position, creating a negative pressure inside the piston cylinder 42. One-way valve one opens and one-way valve two 48 closes, and the external airflow enters the piston cylinder 42 through the air inlet end 47, completing one blowing cycle. Through this reciprocating motion, the blowing device 4 continuously blows away and moves the cleaning brush 310 to clean it, ensuring that the cleaning brush 310 always maintains good cleaning performance, which indirectly guarantees the filtration effect of the filter screen 32 and the power generation efficiency of the vertical axis impeller 23.

[0024] like Figure 8 , Figure 10 and Figure 12 As shown, a collection component 5 is provided on the surface of the air guide hood 25. The collection component 5 includes a collection cover 51 fixed on the surface of the air guide hood 25 and corresponding to the position of the collection opening 251. It is a guiding and gathering component for lint and impurities discharged from the collection opening 251. The bottom surface of the inner wall of the collection cover 51 is through. A support cover 52 is fixed on the surface of the air guide hood 25 and directly below the collection cover 51. It is a mounting support component for the collection box 53 and provides a stable placement space for the collection box 53. The collection box 53 is slidably inserted into the side of the support cover 52 for centralized collection of blown lint and impurities, which is convenient for staff to clean regularly. The collection box 53 is fixed to the support cover 52 by fasteners so that staff can discharge the collected lint and impurities.

[0025] Working Principle: The elevator car 1 is the core carrier of the system. Multiple sets of car frame columns 11 on its sides provide structural support for the car, ensuring its stability and rigidity during operation within the hoistway. The openable car walls 12 enclose the car space, facilitating both maintenance and power generation. The car top device 13 integrates an electrical control module, coordinating the power generation system with elevator operation. The slings 14 connect the car to the top drive system of the hoistway, enabling the car's vertical movement. The power generation device 2 operates continuously as the car moves, converting the pneumatic kinetic energy generated during elevator movement into electrical energy. This stored energy is then used for daily elevator power consumption (such as car lighting and control circuits) or emergency lighting, achieving energy recycling. The generator 24 converts mechanical energy into electrical energy, the rotating shaft 22 transmits power, and the vertical axis impeller 23 captures the airflow during shaft lifting and lowering (especially the directional airflow during high-speed lifting and lowering) to generate rotation; the support frame 21 stably supports the power generation components, the air guide shroud 25 protects the impeller and optimizes the airflow direction, and the horn end 26 adopts a horn-shaped flare design to gather the dispersed airflow in the shaft, further enhancing the rotational power of the vertical axis impeller 23 and improving power generation efficiency.

[0026] The dustproof device 3 employs a self-cleaning mechanism combining filter filtration and cleaning brush cleaning to reduce dust adhesion to the wind turbine. The filter 32 is movably mounted on the inner wall of the air guide shroud 25 via bearing 31, initially filtering dust particles from the airflow in the shaft. A fixing ring 331 is connected to the support platform 33 bearing, ensuring that the filter's rotation and the rotational shaft's movement do not interfere with each other. On the support rod 361 on the inner wall of the air guide shroud 25, a cleaning brush 310 (with inclined bristles) cleans the dust from the filter's surface as it rotates. In the reduction gear transmission, the rotating shaft 22 drives the large gear 34 to rotate, which, after two stages of reduction via small gears 39 and 38, drives the internal gear 321, causing the filter 32 to rotate slowly around bearing 31. The cleaning brush 310 continuously brushes off dust from the filter, achieving self-cleaning and ensuring the wind turbine's wind capture efficiency and power generation stability.

[0027] The blowing device 4 prevents lint from accumulating on the cleaning brush 310 by airflow blowing and lever actuation. The piston cylinder 42 is fixed to the support rod 361 by a pipe clamp 41. The piston rod 43 reciprocates under the action of the cam 46 and the return spring 44, compressing and releasing the airflow within the piston cylinder. One-way valve 1 at the air inlet 47 controls the unidirectional airflow, while one-way valve 2 48 controls the compressed airflow to exit through the nozzle via the connecting pipe 49 and the vent pipe 410, blowing away lint from the cleaning brush 310. The connecting crossbar 412 drives the lever 413 to move with the piston rod, actuating the brush bristles to shake off lint, which is then discharged through the arc-shaped collection opening 251. This reciprocating motion continuously cleans the cleaning brush, indirectly ensuring the filtration effect of the filter and the power generation efficiency of the impeller.

[0028] The collection component 5 completes the closed-loop collection and discharge of lint. The collection cover 51 is set corresponding to the collection opening 251 to guide the lint to converge after discharge; the support cover 52 supports the slidingly inserted collection box 53. The collection box is fixed to the support cover by fasteners, which facilitates the staff to clean the lint and impurities regularly, completes the closed-loop management of the entire cleaning and collection process, and ensures the long-term stable operation of the device.
