For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two components; for ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] Example: Refer to Figure 1 , Figure 2 , Figure 3 and Figure 8A solar chimney system integrating ventilation and lighting comprises a building body 1, a mounting base 2 is fixedly arranged on the top of the building body 1, a glass chimney 3 connected to the interior of the building body 1 is arranged on the mounting base 2, a heat collecting plate 4 is arranged on the inner wall of the glass chimney 3, symmetrically distributed air outlets 301 are opened on both sides of the glass chimney 3, a lighting device 5 is arranged in the glass chimney 3, the lighting device 5 comprises a concentrator 501 for condensing outdoor light, a light channel 502 for reflecting solar light, a concentrating object 503 for concentrating the light inside the light channel 502, and a light scattering object 504 for scattering the light condensed by the concentrating object 503, a solar photovoltaic panel 505 is arranged in the light channel 502, a connecting plate 506 connected to the inner wall of the glass chimney 3 is arranged on the light scattering object 504, and an air inlet 5061 for connecting the building body 1 and the glass chimney 3 is opened on the connecting plate 506.

[0033] Furthermore, the condenser 501 is set to be hemispherical, and the material of the condenser 501 is a light-transmitting acrylic material. The light channel 502 is pasted with a light-guiding material with light-guiding performance. The condensing object 503 adopts a convex lens, and the diffusing object 504 adopts a concave lens.

[0034] Furthermore, the solar photovoltaic panel 505 is electrically connected to a battery, and the battery is used to supply power to the lighting lamps in the building body 1 .

[0035] Specifically, the glass chimney 3 uses the internal heat collecting plate 4 to increase the temperature in the internal channel, thereby accelerating the rising speed of the airflow in the glass chimney 3. The air inside the building body 1 enters the glass chimney 3 through the air inlet 5061, and is finally discharged from the air outlet 301 on the upper side of the glass chimney 3, thereby increasing the indoor temperature change speed of the building body 1. After the external sunlight irradiates the concentrator 501, the concentrator 501 collects the sunlight and transmits it to the light channel 502. The light channel 502 reflects the solar light, and the solar photovoltaic panel 505 absorbs and converts the light. The sunlight collected indoors has the characteristics of full spectrum, no flicker, no glare, and renewable, compared with lighting lamps. The sunlight passing through the glass chimney 3 is further utilized through the lighting equipment 5, thereby optimizing the building energy-saving system and improving the energy-saving efficiency and the utilization rate of solar energy.

[0036] Reference Figure 1-7As a preferred technical solution of the present invention, a dustproof shell 6 is provided on the side of the glass chimney 3, a first cleaning part for cleaning the side wall of the glass chimney 3 is provided in the dustproof shell 6, and a driving component for driving the first cleaning part to work is provided on the mounting seat 2.

[0037] Furthermore, the driving assembly includes a driving motor 7 fixed on the mounting base 2, the output shaft of the driving motor 7 is connected to a driving gear 701 rotating in the mounting base 2, a driven gear 702 meshing with the driving gear 701 is rotatably connected in the mounting base 2, a vertical pipe 8 is fixed on the mounting base 2, a first screw rod 801 is rotatably connected in the vertical pipe 8, the first screw rod 801 is connected to the driven gear 702, a sleeve 802 is threadedly connected to the first screw rod 801, and the sleeve 802 is connected to the first cleaning part through a connecting rod 8021.

[0038] Furthermore, the first cleaning part includes a water storage shell 9 connected to the sleeve 802 through a connecting rod 8021, a movable seat 10 is provided at the bottom of the water storage shell 9, an elastic telescopic member 11 is provided on the movable seat 10, and a movable plate 12 is connected to one end of the elastic telescopic member 11 away from the movable seat 10, and a sponge 121 is provided on the movable plate 12.

[0039] Furthermore, a connecting pipe 13 is provided between the elastic telescopic member 11 and the water storage shell 9 , and one end of the connecting pipe 13 away from the water storage shell 9 passes through the elastic telescopic member 11 and is connected to the movable plate 12 .

[0040] Furthermore, a fixing strip 14 that movably contacts the moving plate 12 is fixedly disposed on the outer wall of the glass chimney 3 , an upper inclined surface is formed on the top of the fixing strip 14 , and a lower inclined surface that movably contacts the upper inclined surface is formed on the bottom of the moving plate 12 .

[0041] Furthermore, a water pipe 16 is arranged in the first screw rod 801 , the water outlet end of the water pipe 16 passes through the dustproof shell 6 and is placed on the upper side of the water storage shell 9 , and the water inlet end of the water pipe 16 is connected to the tap water pipe in the building body 1 .

[0042] Specifically, the glass chimney 3 is placed outdoors, so dust easily adheres to it during long-term use, which affects the lighting effect of the glass chimney 3. Moreover, since it is placed on the top of the building body 1, it is difficult for the staff to clean it from a height, which poses certain safety hazards. By arranging a cleaning part on the outside of the glass chimney 3, the driving component drives the first cleaning part to work, and the first cleaning part automatically cleans the side of the glass chimney 3, thereby ensuring the lighting effect of the glass chimney 3, and further improving the hot pressure ventilation effect of the glass chimney 3.

[0043] The specific working process is as follows: the tap water pipe switch in the building body 1 is turned on, and the tap water pipe introduces cleaning water into the water storage shell 9 through the water pipe 16, but the amount of water entering the water storage shell 9 needs to be controlled; the driving motor 7 is controlled to run, and the output shaft of the driving motor 7 drives the driving gear 701 to rotate. When the driving gear 701 rotates, it meshes with the driven gear 702 at the bottom end of the first screw rod 801 for transmission. The first screw rod 801 rotates in the vertical pipe 8. When the first screw rod 801 rotates, the sleeves 802 respectively threadedly connected on the outer sides of the two move axially, and the two sleeves 802 drive the first cleaning part to work through the connecting rod 8021;

[0044] When the first cleaning part is working, the movable seat 10 moves with the sleeve 802, and the first cleaning part moves out of the dustproof shell 6. The movable seat 10 drives the movable plate 12 and the sponge 121 on its outer side to move through the elastic telescopic member 11. The connecting pipe 13 guides the cleaning water in the water storage shell 9 to the movable plate 12, and then wets the sponge 121 on the movable plate 12. The wetted sponge 121 can effectively wipe the outer wall of the glass chimney 3 during movement. After wiping from one end of the glass chimney 3 to the other end, the water pipe 16 stops conveying cleaning water to the water storage shell 9, and at this time, the movable plate 12 drives the sponge 121 to abut against the fixed strip 14 of the glass chimney 3. As the movable plate 12 continues to move, the elastic telescopic member 11 is compressed, and the sewage in the sponge 121 is squeezed out during the squeezing process, and then the control The driving motor 7 drives the driving gear 701 to rotate in the opposite direction, so that the driving assembly drives the first cleaning part to move back. After the sponge 121 moving seat 10 moves back, it no longer abuts against the fixed strip 14 and contacts the outer wall of the glass chimney 3 again, so that the sponge 121 that no longer contains too much water can wipe the glass chimney 3 for the second time. The sponge 121 can also absorb the residual moisture on the glass chimney 3 during the second wiping process, so as to prevent dust in the air from easily adhering to the glass chimney 3 again with the moisture, thereby ensuring the wiping effect of the glass chimney 3, until the moving seat 10 drives the sponge 121 to enter the dustproof shell 6, so as to prevent dust from accumulating on the outside of the sponge 121 when not in use, thereby ensuring the cleaning effect of the glass chimney 3 when the sponge 121 is used later, and the cleaned glass chimney 3 always maintains a good lighting effect.

[0045] Reference Figure 1-7 As a preferred technical solution of the present invention, a partition 15 is slidably connected to the dustproof shell 6, and both sides of the partition 15 are provided with extrusion slopes 151 that are against the movement of the first cleaning part. The partition 15 is placed on the outer side of the dustproof shell 6. A side plate 152 is fixed at one end, and an elastic element 153 is arranged between the side plate 152 and the outer wall of the dustproof shell 6.

[0046] Specifically, when the movable seat 10 and the water storage shell 9 are moved out of the dustproof shell 6, the movable seat 10 applies a force to the extrusion slope 151 of the partition 15, so that the partition 15 moves toward the outside of the dustproof shell 6, so as to prevent the partition 15 from hindering the cleaning part from moving out of the dustproof shell 6 and hindering the cleaning part from cleaning the glass chimney 3. After the cleaning part moves out of the dustproof shell 6, the partition 15 is reset under the elastic pull of the elastic element 153; when the cleaning part moves back, the water storage shell 9 applies a thrust to the extrusion slope 151 of the partition 15, and the partition 15 moves toward the outside of the dustproof shell 6 again to avoid the return of the cleaning part. After the cleaning part moves back to the inside of the dustproof shell 6, the partition 15 blocks the opening of the dustproof shell 6 to ensure the sealing of the dustproof shell 6 and prevent dust from accumulating on the outside of the cleaning part when not in use, which affects the cleaning effect of the glass chimney 3 during subsequent use.

[0047] 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.
