Description

Technical Field

[0001] This invention relates to the field of greening and planting technology, specifically to an integrated device for vertical axis wind power generation and greening of building facades. Background Technology

[0002] Currently, greening building facades and wind energy utilization within the building itself are typically two independent technological systems. Green building structures often employ simple wall-mounted flower troughs or external supports, relying on manual or drip irrigation for watering. This lack of a tiered water supply mechanism that automatically adjusts according to water storage capacity leads to uneven water distribution at different heights or locations, resulting in localized overwatering or underwatering. Existing wind energy utilization methods usually depend on rooftop wind turbines, making integration with building facade structures difficult. Furthermore, there is no linkage mechanism between existing greening structures and wind power systems, preventing the use of wall arrangement structures to regulate airflow and create a favorable environment for increased airflow, resulting in insufficient utilization of wind energy resources on building facades. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, the present invention provides the following technical solution: a vertical axis wind power generation and greening integrated device for building facades, comprising a power generation component and multiple greening components, wherein the power generation component includes a three-way ventilation drain buried underground, a drive pipe fixedly connected to the three-way ventilation drain, a generator coaxially fixed inside the drive pipe via multiple generator brackets, leaving a gap between the inner wall of the drive pipe and the outer surface of the generator for airflow, and an impeller fixed on the input shaft of the generator; it also includes a through component, the through component comprising a through component buried underground The ventilation drainage system is interconnected with the three-way ventilation drainage system. Each ventilation drainage channel is equipped with a mounting support cover, and each mounting support cover has two greening components. Each greening component includes a wall support cylinder, with a water distribution pipe located at the center of the cylinder's axis. The bottom end of the water distribution pipe passes through the mounting support cover into the ventilation drainage channel, and the water distribution pipe is fixedly fitted to the mounting support cover. Multiple planting grooves for planting greenery are fixedly installed on the circumferential surface of the wall support cylinder along its axial direction. No greenery is planted between adjacent wall support cylinders; that is, the closest points between two wall support cylinders are not planted.

[0004] Preferably, the top end of the drive tube is suspended and fixed with a top cap coaxial with the drive tube by multiple support rods. The circumferential surface of the top cap is provided with multiple air inlets along its own tangential direction to guide external air into the interior of the top cap along the inner wall of the top cap.

[0005] Preferably, the top cap is fixedly installed on the outer sleeve, the outer sleeve is coaxially sleeved on the outside of the drive tube, and there is a gap between the inner wall of the outer sleeve and the outer surface of the drive tube. The bottom of the outer surface of the drive tube is slidably and rotatably fitted with a low cover, which is threadedly engaged with the bottom end of the outer sleeve to facilitate the disassembly and assembly of the low cover. The low cover is used to seal the bottom end of the outer sleeve.

[0006] Preferably, a water storage tank is fixedly installed at the top of each wall support cylinder, and an inlet is opened at the top of the water distribution pipe. The water distribution pipe is connected to the inside of the water storage tank through the inlet. A sealing plate is magnetically sealed at the bottom surface of the water storage tank and the inlet at a position coaxial with the inlet. The sealing plate is used to block the connection between the water distribution pipe and the water storage tank.

[0007] Preferably, an inner pipe and an outer pipe are arranged equidistantly and sequentially along their axial direction on the circumferential surface of the water distribution pipe. In each set of inner and outer pipes, the outer pipe is positioned below the inner pipe, and the length of the inner pipe is shorter than the length of the outer pipe. The water distribution pipe has two sets of symmetrically arranged inner and outer pipes at the same height. The inner pipe extends to the outer side of the circumferential surface of the wall support cylinder, with one end of the inner pipe above the planting ring groove. The outer pipe extends to the outer side of the circumferential surface of the planting ring groove.

[0008] Preferably, a switching control layer pipe is slidably mounted on the inner wall of the water distribution pipe, with a movement space between the top end of the switching control layer pipe and the top end of the water distribution pipe; an inner opening is provided on the circumferential surface of the switching control layer pipe at a position corresponding to all the inner through pipes, and an outer opening is provided on the circumferential surface of the switching control layer pipe at a position corresponding to all the outer through pipes; and an inner narrow opening and an outer narrow opening are respectively provided below each inner and outer opening on the circumferential surface of the switching control layer pipe; wherein the diameter of all the inner and outer narrow openings decreases sequentially from top to bottom on the switching control layer pipe.

[0009] Preferably, a plurality of linkage steel rod support frames are fixedly installed on the inner wall of the water storage distribution pipe, arranged axially along the water storage distribution pipe. The linkage steel rod support frames are used to slide the linkage steel rods, which are coaxially arranged on the inner side of the water storage distribution pipe. The top end of the linkage steel rod is fixedly engaged with the sealing plate. The switching control layer pipe is also provided with a plurality of sliding grooves for the linkage steel rod support frames to pass through. The linkage steel rod support frames are slidably arranged on the inner side of the sliding grooves. The linkage steel rod support frames and the sliding grooves are also used to limit the sliding range of the switching control layer pipe on the inner wall of the water storage distribution pipe.

[0010] Preferably, a limit frame is fixedly installed on the inner wall of the switching control layer pipe. The limit frame is slidably sleeved on the circumferential surface of the linkage steel rod. A limit ring is fixedly installed on the linkage steel rod, and the limit ring contacts and cooperates with the limit frame. A float is fixedly installed at the bottom end of the switching control layer pipe. A bottom sealing head that contacts and seals with the bottom of the water storage distribution pipe is also fixedly installed at the bottom end of the linkage steel rod.

[0011] Preferably, an electric cylinder is fixedly installed on the mounting support cover plate in each through-type assembly. The end of the telescopic rod of the electric cylinder extends into the interior of the through-type air drain, and a crossbeam is fixedly installed on the end of the telescopic rod of the electric cylinder. The crossbeam is fixedly connected to the two bottom sealing heads by elastic gaskets.

[0012] Compared with the prior art, the present invention has the following beneficial effects: (1) The present invention uses a combination of water storage distribution pipe, switching control layer pipe, inner and outer through pipes and a gradually decreasing narrowing structure to automatically adjust the effective water outlet cross-sectional area of ​​each through pipe according to the height during irrigation. Due to the large water pressure at the top and small water pressure at the bottom, the traditional structure is prone to the problem of large water volume at the bottom and insufficient water volume at the top. However, the present invention accurately compensates for the water pressure difference by gradually decreasing the narrowing of the narrowing, thereby ensuring that each planting ring trough receives a balanced water supply. This balancing mechanism is achieved entirely by the structure and does not rely on electronic valves, which greatly reduces the complexity of the control system and achieves a long-term stable and reliable adaptive water distribution effect; (2) The present invention arranges multiple wall support cylinders evenly to form a stable narrow tube effect between adjacent cylinders, and the flow velocity is significantly increased when the ambient airflow enters the gap. According to Bernoulli's principle, the increase in flow velocity leads to a decrease in pressure, thereby forming a continuous negative pressure zone in the through air drain and the three-way air drain, so that the air inlet with the top cap obtains a forced air intake effect. Compared with the traditional method of relying on natural wind to directly enter the wind turbine, the present invention can actively increase the airflow by utilizing the geometric structure of the building facade, thereby greatly improving the effective driving force of the impeller, enabling wind energy collection even in low wind speed environments, significantly improving the availability and output stability of the power generation device, and the wind turbine blades do not protrude from the exterior wall, making the overall appearance more harmonious, and since the wind turbine blades are not exposed, they will not cause harm to people; (3) The present invention sets a float inside the water storage distribution pipe and links it with the switching control layer pipe, and reliably constrains its movement range through the limit frame and limit ring. In this way, when the airflow passes through the greening components and causes the air pressure inside the water storage distribution pipe to fluctuate, the float will not be pushed up by the airflow, thus preventing accidental triggering of the irrigation switching action. Only when water is injected into the water storage pipe and reaches a certain water level will the float rise steadily, realizing the precise position adjustment of the switching layer.

Detailed Implementation

[0025] The following is in conjunction with the appendix Figures 1-11 The technical solution of the present invention will be further illustrated through specific embodiments.

[0026] This invention provides an integrated vertical axis wind power generation and greening device for building facades, comprising a power generation component and multiple greening components. The power generation component includes a three-way ventilation drain 102 buried underground, with a drive pipe 101 fixedly connected to the three-way ventilation drain 102. A generator 109 is coaxially fixed inside the drive pipe 101 via multiple generator brackets 108, leaving a gap between the inner wall of the drive pipe 101 and the outer surface of the generator 109 for airflow. An impeller 110 is fixed to the input shaft of the generator 109. The device also includes a connecting component, comprising a connecting ventilation drain 201 buried underground, which connects to... The three-way ventilation drains 102 are interconnected. Each ventilation drain 201 is fixed with a mounting support cover 202, and each mounting support cover 202 is fixed with two greening components. The greening components include wall support cylinders 301. A water storage and distribution pipe 305 is set at the axial position inside the wall support cylinder 301. The bottom end of the water storage and distribution pipe 305 passes through the mounting support cover 202 into the ventilation drain 201, and the water storage and distribution pipe 305 is fixedly engaged with the mounting support cover 202. The circumferential surface of the wall support cylinder 301 is fixedly installed with multiple planting ring grooves 302 for planting greenery along its own axial direction. No greenery is planted between two adjacent wall support cylinders 301, that is, the closest position between two wall support cylinders 301. A top cap 105, coaxial with the drive tube 101, is suspended and fixed at the top end of the drive tube 101 by multiple support rods 104. Multiple air inlets 106 are provided tangentially on the circumferential surface of the top cap 105 to guide external air tangentially into the top cap 105 along its inner wall. The top cap 105 is fixedly mounted on an outer sleeve 107, which is coaxially fitted around the outside of the drive tube 101, with a gap between the inner wall of the outer sleeve 107 and the outer surface of the drive tube 101. A bottom cover 103 is slidably and rotatably fitted onto the bottom of the outer surface of the drive tube 101. The bottom cover 103 is threadedly engaged with the bottom end of the outer sleeve 107, facilitating its installation and removal. The bottom cover 103 is used to seal the bottom end of the outer sleeve 107. A water storage tank 303 is fixedly installed at the top of the wall support cylinder 301. A water inlet 306 is opened at the top of the water distribution pipe 305. The water distribution pipe 305 is connected to the inside of the water storage tank 303 through the water inlet 306. A sealing plate 304 is magnetically contacted and sealed at the bottom surface of the water storage tank 303 and the water inlet 306 at the same position. The sealing plate 304 is used to block the connection between the water distribution pipe 305 and the water storage tank 303.On the circumferential surface of the water distribution pipe 305, inner pipes 309 and outer pipes 308 are arranged at equal intervals and intersecting along their own axis. In each set of inner pipes 309 and outer pipes 308, the outer pipe 308 is located below the inner pipe 309, and the length of the inner pipe 309 is shorter than the length of the outer pipe 308. There are two sets of symmetrically arranged inner pipes 309 and outer pipes 308 at the same height on the water distribution pipe 305. The inner pipe 309 extends to the outer side of the circumferential surface of the wall support cylinder 301, so that one end of the inner pipe 309 is located above the planting ring groove 302. The outer pipe 308 extends to the outer side of the circumferential surface of the planting ring groove 302.

[0027] A switching control layer pipe 311 is slidably mounted on the inner wall of the water distribution pipe 305, with a movement space between the top end of the switching control layer pipe 311 and the top end of the water distribution pipe 305; an inner through-hole 314 is opened on the circumferential surface of the switching control layer pipe 311 at a position corresponding to all the inner through-holes 309, and an outer through-hole 315 is opened on the circumferential surface of the switching control layer pipe 311 at a position corresponding to all the outer through-holes 308; and an inner narrowed opening 316 and an outer narrowed opening 317 are respectively opened below each inner through-hole 314 and outer through-hole 315 on the circumferential surface of the switching control layer pipe 311; wherein the diameter of all the inner narrowed openings 316 and outer narrowed openings 317 on the switching control layer pipe 311 decreases sequentially from top to bottom. Multiple linkage steel rod support frames 313 are fixedly installed on the inner wall of the water distribution pipe 305, arranged axially along the water distribution pipe 305. The linkage steel rod support frames 313 are used to slide the linkage steel rod 307. The linkage steel rod 307 is coaxially arranged on the inner side of the water distribution pipe 305, and the top of the linkage steel rod 307 is fixedly engaged with the sealing plate 304. The switching control layer pipe 311 is also provided with multiple sliding grooves 312 for the linkage steel rod support frames 313 to pass through. The linkage steel rod support frames 313 are slidably arranged on the inner side of the sliding grooves 312. The linkage steel rod support frames 313 and the sliding grooves 312 are also used to limit the sliding range of the switching control layer pipe 311 on the inner wall of the water distribution pipe 305.

[0028] A limit bracket 319 is fixedly installed on the inner wall of the switching control layer pipe 311. The limit bracket 319 slides on the circumferential surface of the linkage steel rod 307. A limit ring 318 is fixedly installed on the linkage steel rod 307, and the limit ring 318 contacts and cooperates with the limit bracket 319. A float 320 is fixedly installed at the bottom end of the switching control layer pipe 311. A bottom sealing head 310 that contacts and seals with the bottom of the water storage distribution pipe 305 is also fixedly installed at the bottom end of the linkage steel rod 307. An electric cylinder 203 is fixedly installed on the mounting support cover plate 202 in each through-type assembly. The telescopic rod end of the electric cylinder 203 extends into the through-type air drain 201, and a crossbeam 204 is fixedly installed at the telescopic rod end of the electric cylinder 203. The crossbeam 204 is fixedly connected to the two bottom sealing heads 310 through elastic gaskets 205.

[0029] All the interconnecting components are connected in series. An appropriate number of power generation components are selected based on environmental needs. The three-way venting drains 102 within the power generation components are connected in series between two of the interconnecting venting drains 201. When the power generation component is located at the outermost edge, one side of the three-way venting drain 102 needs to be sealed. After installation, greenery is planted on the planting ring trough 302, and a sensor for detecting soil moisture is installed within the planting ring trough 302. When the moisture level falls below a threshold, the greenery is watered. A water storage tank 303 is included to collect rainwater, which is then used as the water source for watering. When watering, the telescopic rod of the electric cylinder 203 is retracted, which drives the bottom sealing head 310 to contact and seal with the bottom end of the water storage and distribution pipe 305 through the crossbeam 204 and the elastic gasket 205 (the function of the elastic gasket 205 is to provide elasticity so that there is always contact pressure when the bottom sealing head 310 contacts the bottom of the water storage and distribution pipe 305), blocking the bottom of the water storage and distribution pipe 305. At the same time, the bottom sealing head 310 will also drive the sealing plate 304 to move upward through the linkage steel rod 307, so that the sealing plate 304 no longer blocks the water inlet 306. At this time, the water inside the water storage tank 303 will enter the water distribution pipe 305 through the inlet 306. During the entry process, the bottom of the water distribution pipe 305 is sealed, causing water to accumulate inside. At this time, the float 320 will be subjected to buoyancy, and then the float 320 will drive the switching control layer pipe 311 to move upward synchronously. When the top of the switching control layer pipe 311 moves to the top of the water distribution pipe 305, it will stop. At this time, the inner opening 314 and the inner pipe 309, as well as the outer pipe 308 and the outer opening 315, will be staggered, and the inner narrow opening 31 will open. Alignment 6 is with the inner through pipe 309, and alignment of the outer through pipe 308 with the outer constricted opening 317. This results in the diameter of the openings connecting the water storage and distribution pipe 305 to the inner through pipe 309 and the outer through pipe 308 decreasing sequentially from top to bottom. This is because the water pressure at the bottom of the water storage and distribution pipe 305 is greater than the water pressure at the top. To ensure consistent water flow in each set of inner through pipes 309 and outer through pipes 308, the flow cross-sectional area of ​​the inner through pipes 309 and outer through pipes 308 needs to be limited layer by layer. This ensures that the plants in each planting ring trough 302 receive effective irrigation. It should be noted that, at this time, because the limiting ring 318 moves upward following the linkage steel rod 307, there is movement space between the limiting ring 318 and the limiting frame 319, allowing the switching control layer pipe 311 to move upward smoothly. After watering is completed, the telescopic rod of the electric cylinder 203 extends, separating the bottom sealing head 310 from the bottom of the water storage and distribution pipe 305, allowing all the water inside the water storage and distribution pipe 305 to be poured out. At the same time, the sealing plate 304 blocks the water inlet 306 again.Since there is no water inside the water distribution pipe 305, under the action of gravity, the float 320 drives the switching control layer pipe 311 to slide down to the initial position, so that the inner port 314 and the inner pipe 309 and the outer port 315 and the outer pipe 308 are realigned.

[0030] When there is wind in the environment, the airflow will pass between two adjacent wall support cylinders 301. Due to the narrowing effect formed between the two wall support cylinders 301, the air velocity between them will increase. According to Bernoulli's principle, the pressure is lower where the velocity is higher. This will cause the air pressure inside all the inner and outer pipes 309 and 308 to flow away from the water storage and distribution pipe 305. At this time, the pressure inside the water storage and distribution pipe 305 will decrease, and the pressure inside the interconnected through-flow air drain 201 and the three-way air drain 102 will also decrease. It should be noted that because multiple through-flow components and greening components are installed, the distance between the wall support cylinders 301 in each greening component is the same, thus a narrowing effect can be formed between any two adjacent wall support cylinders 301. The pressure reduction inside the through-hole 201 causes external air to enter the top cap 105 tangentially through the air inlet 106. If solid particles are mixed in with the air, they will rotate with the air. Therefore, the impurity particles will rotate against the inner wall of the outer sleeve 107 due to centrifugal force, while the air separates from the impurity particles. The air then passes through the support rod 104 and enters the drive pipe 101, driving the impeller 110 to rotate. The impeller 110 drives the input shaft of the generator 109 to rotate, thereby enabling the generator 109 to generate electrical energy. At the same time, the separated solid impurity particles will gradually decrease in speed due to friction with the inner wall of the outer sleeve 107, eventually falling into the gap between the outer sleeve 107 and the drive pipe 101. Periodically rotating the bottom cover 103 and removing it allows the solid impurity particles between the drive pipe 101 and the outer sleeve 107 to be discharged. Throughout the process, the airflow passes through the float 320. To prevent the float 320 from being driven by the airflow, a limiting ring 318 and a limiting frame 319 are installed. If the float 320 moves upward due to airflow resistance, it needs to simultaneously drive the switching control layer pipe 311 and the limiting frame 319 upward. Since the upward movement of the limiting frame 319 is restricted by the limiting ring 318, and the limiting ring 318 is synchronized with the linkage steel rod 307 and the bottom sealing head 310, the float 320 will not be pushed by the airflow as long as the telescopic rod of the electric cylinder 203 does not retract. This ensures the flow cross-sectional area of ​​the inner through pipe 309 and the outer through pipe 308.
