[0030] Example: Refer to Figure 1-6A green building based on solar chimney includes a building body 1, a roof 101 for people to walk on is arranged on the top of the building body 1, a solar photovoltaic panel 1011 is arranged on the roof 101 for people to walk on, a chimney body 2 is arranged on the top of the roof 101 for people to walk on, an exhaust passage for hot air to rise is formed in the chimney body 2, a black heat-absorbing wall panel 201 for heating the air inside the exhaust passage is arranged in the chimney body 2, two solar rooms 3 are arranged on the south facade of the building body 1, a water spraying assembly is arranged in the solar room 3, a plurality of soilless cultivation racks 4 adopting substrate cultivation technology are arranged in the solar room 3, and a driving part for driving the soilless cultivation racks 4 to swing is arranged in the chimney body 2.

[0031] Furthermore, two chimney bodies 2 are provided and symmetrically arranged on the roof of the building body 1. The four sides of the chimney body 2 are all glass surfaces. Two black heat-absorbing wall panels 201 are arranged in each chimney body 2. The two black heat-absorbing wall panels 201 are cross-distributed in the channel of the chimney body 2. An installation groove for installing the black heat-absorbing wall panels 201 is opened on the glass surface of the chimney body 2.

[0032] Furthermore, an air inlet 301 is provided at the top of the south facade of the solar room 3, an air inlet window 302 connected to the building body 1 is provided on the side of the solar room 3 away from the air inlet 301, a working door 303 is also provided on one side of the solar room 3, and all surfaces of the solar room 3 are made of glass.

[0033] Specifically, the solar photovoltaic panel 1011 on the top of the building body 1 absorbs and converts sunlight, thereby improving the utilization rate of sunlight by the building body 1 and providing electric energy for the internal electrical appliances of the building body 1. The chimney body 2 is covered with glass on all four sides, and two layers of crossed black heat-absorbing wall panels 201 are arranged inside. The chimney body 2 is installed on the south facade of the building. Solar radiation shines on the black heat-absorbing wall panels 201 through the transparent glass panels, so that the black heat-absorbing wall panels 201 absorb heat and heat the air in the chimney channel. The air temperature in the chimney channel rises, and the hot air flows upward along the channel and flows out from the top of the chimney body 2. At this time, a density difference is generated inside and outside the chimney channel, and the indoor air is sucked into the chimney channel to complete the conversion from thermal pressure to wind pressure, so as to drive the air in the chimney channel to flow upward. At this time, the indoor air is continuously sucked in, making the indoor The air flows continuously to form wind, causing the indoor heat to be continuously taken away, thereby lowering the indoor temperature and reducing the energy consumption of air conditioning, thereby effectively promoting natural ventilation inside the building; soilless cultivation technology is used to grow plants, oxygen is provided, and the air inlet 301 and the air inlet window 302 are used to adjust the air. The setting of the working door 303 facilitates the entry and exit of personnel and plant management; and the water spraying component located on the top of the solar room 3 sprays water regularly to meet the water needs of the plants and assist in indoor temperature regulation; the solar chimney and the water spraying component jointly enhance natural ventilation and improve living comfort. In addition, the soilless cultivation rack 4 inside the solar room 3 adopts substrate cultivation technology to grow vegetables, fruits and flowers, etc., which realizes the effective use of resources and optimization of the environment, aiming to achieve a green and energy-saving building model, reduce dependence on external energy, and improve the sustainability of house construction.

[0034] Reference Figure 1-7 As a preferred technical solution of the present invention, the soilless cultivation rack 4 includes two ear plates 401 fixedly mounted on the inner bottom wall of the solar room 3, a rotating rod 402 is arranged between the two ear plates 401, a torsion spring is arranged between the rotating rod 402 and the ear plate 401, both ends of the rotating rod 402 are connected with mounting plates 403, a plurality of fixed rods 404 are fixedly arranged between the two mounting plates 403, both ends of each fixed rod 404 are movably connected with a ring 405, a cultivation tray 406 is arranged between the two rings 405, and a counterweight block is arranged at the bottom of the cultivation tray 406.

[0035] Furthermore, the driving part includes a rotating shaft 5 rotatably connected to the chimney body 2, a plurality of force plates 501 are arranged on the rotating shaft 5, a gear box 502 is fixedly arranged on the outside of the chimney body 2, the rotating shaft 5 passes through one end of the chimney body 2 and is connected to the input shaft of the gear box 502, the output shaft of the gear box 502 is connected to the transmission rod 6 rotating in the solar room 3, an incomplete bevel gear 602 is arranged at the bottom of the transmission rod 6, and a driven bevel gear 4021 intermittently meshing with the incomplete bevel gear 602 is arranged on the rotating rod 402 of one of the soilless cultivation racks 4.

[0036] Furthermore, a synchronous wheel 7 is disposed on the rotating rods 402 of two adjacent soilless cultivation racks 4 , and a synchronous belt is disposed between the two synchronous wheels 7 .

[0037] Furthermore, a chimney cap 202 is provided on the top of the chimney body 2 , and a guide block 203 for guiding airflow is provided inside the chimney body 2 .

[0038] Specifically, a chimney cap 202 is added to the top of the chimney to allow the airflow in the pipeline to be discharged from both sides of the top of the chimney to prevent rainwater and other debris from entering the chimney; the guide block 203 inside the chimney body 2 guides the flowing airflow, and the airflow blows on the force-bearing plate 501, and the force-bearing plate 501 drives the rotating shaft 5 to rotate. The rotating shaft 5 serves as a driving source to drive the input shaft of the gear box 502 to rotate. Through the transmission between the gears in the gear box 502, the output shaft of the gear box 502 is meshed and driven by the gears inside the box body, so that the low-speed motion is converted into high-speed motion, and the output of the gear box 502 is The output shaft drives the incomplete bevel gear 602 on the lower side of the transmission rod 6 to intermittently mesh with the driven bevel gear 4021 of one of the rotating rods 402 of the soilless cultivation rack 4. The rotating rods 402 of the two adjacent soilless cultivation racks 4 rotate together through the synchronous wheel 7 and the synchronous belt. When the incomplete bevel gear 602 meshes with the driven bevel gear 4021, the rotating rod 402 drives the cultivation tray 406 to swing through the mounting plate 403. The setting of the counterweight block at the bottom of the cultivation tray 406 makes it always face downward when swinging, so as to prevent the plants in the tray from falling. 2 is not meshed with the driven bevel gear 4021, the rotating rod 402 is reset and rotated under the action of the torsion spring, so that the soilless cultivation rack 4 swings back and forth; the hot air flowing inside the chimney body 2 is used as the power source of the driving part, so that the driving part drives the soilless cultivation rack 4 inside the solar room 3 to swing left and right, without the need for additional power equipment, thereby reducing the construction cost. If the soilless cultivation rack 4 is fixedly placed layer by layer, as the sun moves, the plants placed on the lower layer cannot get the same light intensity as the plants on the upper layer, which will result in the light intensity received by plants at different heights being different. Different, for example, at noon, the sunlight is vertically downward, and the plants placed on the lower side cannot get light. Only after the sun shifts, the plants in the lower layer can wait for light, but the light intensity at this time is different from that in the morning. By swinging the soilless cultivation rack 4, the plants on each layer of the soilless cultivation rack 4 can receive the same light intensity, avoiding uneven plant growth, and the swinging soilless cultivation rack 4 prevents the cultivation trays 406 on each layer from being blocked from each other for a long time, thereby ensuring the photosynthesis of the plants, thereby providing sufficient oxygen for the building body 1.

[0039] Reference Figure 6As a preferred technical solution of the present invention, further, a limit block 8 is fixed on the rotating rod 402 and the fixed rod 404, and an arc groove 801 matching with the limit block 8 is opened on the mounting plate 403 and the collar 405.

[0040] Specifically, by setting a limit block 8 and an arc groove 801 that cooperates with the limit block 8, the rotation angle, that is, the rotation range, of the rotating rod 402 and the ring 405 can be limited to ensure that the soilless cultivation frame 4 swings in an orderly manner and avoid the plants in the cultivation tray 406 from falling due to excessive swinging amplitude.

[0041] Reference Figure 4-5 As a preferred technical solution of the present invention, further, a fixing plate 9 is fixedly provided on the inner wall of the solar room 3, and a plurality of rotating rods 901 are rotatably connected to the fixing plate 9. Fan blades 902 and second bevel gears 903 are respectively provided at both ends of the rotating rods 901, and a first bevel gear 603 meshing with the second bevel gear 903 is provided on the transmission rod 6.

[0042] Specifically, when the transmission rod 6 rotates, the first bevel gear 603 on the outside is meshed with the second bevel gear 903 on the rotating rod 901 for transmission, and the second bevel gear 903 drives the rotating rod 901 and the fan blades 902 at the end of the rotating rod 901 to rotate. The fan blades 902 can accelerate the air flow in the solar room 3, and the fast-flowing air accelerates the rapid evaporation of water on the leaves of vegetables, fruits and flowers planted in the soilless cultivation rack 4, which helps to reduce the temperature in the solar room 3 through water evaporation, thereby improving the energy efficiency of the building.

[0043] Reference Figure 7 As a preferred technical solution of the present invention, further, the water spray assembly includes a water tank 10 arranged on the top of the solar room 3, a water pump 1001 is fixedly provided on the water tank 10, the water outlet of the water pump 1001 is connected to a main pipeline 1002, a plurality of branch pipelines 1003 are arranged on the main pipeline 1002, and a plurality of atomizing nozzles 1004 are arranged on each branch pipeline 1003.

[0044] Specifically, when the water spraying component is working, the water pump 1001 draws clean water from the water tank 10 by intelligently controlling the water spraying time. The clean water is sprayed on the plants planted on the soilless cultivation rack 4 through the main pipe 1002, the branch pipe 1003 and the atomizing nozzle 1004 in turn, so as to create an indoor environment suitable for plant growth. At the same time, the evaporation of water helps to reduce the temperature in the solar room 3 and improve the energy efficiency of the building. The water tank 10 is designed on the roof. During the water spraying process, the pressure in the water pipe is higher than that of pumping water from bottom to top, and the water spraying efficiency of the nozzle or the power consumption of pumping water will be relatively much lower.

[0045] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
