[0031] Referring to Figures 1-3 As shown, an embodiment of the present application provides a seat air supply system, which includes a bottom plate 1, an air-conditioning air supply duct 3, a primary air supply duct 5, a secondary air supply duct 6 and a tertiary air supply duct 7. The bottom plate 1 is arranged below the grandstand plate 2 and connected to the grandstand plate 2. A sealed cavity is formed between the bottom plate 1 and the grandstand plate 2. An air outlet 21 is provided on the grandstand plate 2 at each seat. The air-conditioning air supply duct 3 is arranged outside the sealed cavity. The primary air supply duct 5 is arranged between the bottom plate 1 and the grandstand plate 2 and extends along the arrangement direction of a row of seats. The primary air supply duct 5 is connected to the air-conditioning air supply duct 3 through an air supply branch pipe 4 passing through the bottom plate 1. A plurality of secondary air supply ducts 6 are provided and connected to the primary air supply duct 5. The secondary air supply ducts 6 extend along the arrangement direction of a row of seats. The plurality of secondary air supply ducts 6 are arranged at intervals along the length direction of the primary air supply duct 5. Each air outlet 21 is connected to a secondary air supply duct 6 through a tertiary air supply duct 7.

[0032] Referring to Figures 1-3 As shown, specifically, the bottom plate 1 is arranged below the grandstand plate 2 and is spaced from the grandstand plate 2. The bottom plate 1 is fixedly connected to the grandstand plate 2 and the building main body through a keel 11. The periphery of the bottom plate 1 is hermetically connected to the grandstand plate 2 and the building main body, so as to form a sealed cavity between the bottom plate 1 and the grandstand plate 2. The primary air supply duct 5 and the secondary air supply duct 6 are both made of heat-insulating air ducts to reduce energy loss during the air supply process. The tertiary air supply duct 7 is made of a flexible hose, which is convenient for construction.

[0033] Referring to Figures 1-3As shown in the figure, the air-conditioning supply duct 3 extends along the arrangement direction of a row of seats. There are multiple first-stage supply ducts 5, and the multiple first-stage supply ducts 5 are arranged at intervals along the length direction of the air-conditioning supply duct 3. A plurality of second-stage supply ducts 6 are connected to each first-stage supply duct 5. Specifically, the grandstand is divided into multiple regions along the arrangement direction of a row of seats, and one first-stage supply duct 5 is arranged in each region. Each first-stage supply duct 5 is connected to the air-conditioning supply duct 3 through a supply air branch pipe 4. A plurality of second-stage supply ducts 6 are connected to each first-stage supply duct 5, and the air outlets 21 of one region are connected to the second-stage supply ducts in this region through third-stage supply ducts 7. Further, a air volume regulating valve 8 is arranged on each supply air branch pipe 4. The multiple first-stage supply ducts supply air to multiple regions respectively, and the air volume regulating valve 8 is used to control the air volume of each supply air branch pipe 4, and control the air volume of each first-stage supply duct 5, so as to realize the control of the air volume of each region. The air volume can be adjusted according to the number of people in each region and the air supply demand, so as to ensure the air volume balance of each region of each grandstand.

[0034] In this embodiment, one end of the second-stage supply duct 6 is connected to the first-stage supply duct 5, and the other end extends away from the first-stage supply duct 5. A plurality of second-stage supply ducts 6 are arranged on both sides of the first-stage supply duct 5.

[0035] In order to keep the air supply volume at each seat in the area supplied by one first-stage supply duct 5 balanced, when arranging the multiple second-stage supply ducts 6 connected to one first-stage supply duct 5, along the direction away from the supply air branch pipe 4, the diameter of the second-stage supply duct 6 gradually increases, and at the same time, the distance between adjacent second-stage supply ducts 6 gradually decreases. Moreover, for the multiple third-stage supply ducts 7 connected to one second-stage supply duct 6, along the length direction of the second-stage supply duct 6 and away from the first-stage supply duct 5, the diameter of the third-stage supply duct 7 gradually increases.

[0036] Since in the first-stage supply duct 5, the air volume is smaller the farther away from the supply air branch pipe 4, so setting the multiple second-stage supply ducts 6 on one first-stage supply duct 5 to have different diameters and different distances can make the air volume entering each second-stage supply duct 6 consistent. At the same time, the multiple third-stage supply ducts 7 connected to one second-stage supply duct 6 are also set to have different diameters, so that the air volume entering each third-stage supply duct 7 is also consistent, thus ensuring that the air volume supplied to each seat is consistent, and ensuring the balance of the air supply volume at each seat in the area supplied by one first-stage supply duct 5.

[0037] Refer to Figures 2-3As shown in the figure, further, to ensure the fire safety of the grandstand area, the bottom plate 1 is a fireproof and heat-insulating plate; the air supply branch pipe 4 is a fireproof air duct, and a fire damper 9 is provided on each air supply branch pipe 4. Specifically, the fire damper 9 is provided at the place where the air supply branch pipe 4 passes through the bottom plate 1. Through this setting, the fireproof performance of the air supply system can be improved, and the safety of the grandstand area can be ensured. Compared with the traditional setting of fire dampers 9 at each air outlet, the number of fire dampers 9 can be reduced, the fire hazards can be reduced, and the inspection and maintenance are easy.

[0038] The air outlet 21 on the grandstand plate 2 can be set on the tread or the kick surface of the step surface, and it can be set according to the seat position to ensure the air supply effect at the seat position.

[0039] To improve the sound insulation effect of the grandstand area, a sound-absorbing coating 10 is provided on the bottom surface of the grandstand plate 2 to absorb the noise of the ventilation system through the sound-absorbing coating 10. Further, the primary air supply pipe 5 and the secondary air supply pipe 6 are respectively installed on the grandstand plate 2 through a shock-absorbing structure to reduce the noise generated by the vibration of the air supply pipes. Specifically, the shock-absorbing structure can adopt a spring shock absorber. Through the cooperation of the shock-absorbing structure and the sound-absorbing coating 10 on the grandstand plate 2, the noise of the air supply system can be reduced, and the noise of the grandstand area can be reduced, keeping the grandstand area quiet.

[0040] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
