[0019] The following is combined with Figure 1 This application is described in further detail.
[0020] A structure for natural lighting and ventilation of an underground space of a building comprises a cavity 3 formed by soil 1 and an outer wall 2 of the underground space.
[0021] An acrylic cover plate 4 is fixedly arranged on the cavity 3, an acrylic support plate 5 is fixedly arranged on the acrylic cover plate 4, the other end of the acrylic support plate 5 is fixedly arranged on the soil 1, and an outdoor ventilation hole 6 is opened on the acrylic support plate 5; the height of the acrylic support plate 5 is greater than 1 meter.
[0022] The cavity 3 is provided with a heat collecting device 7 and a light guiding device 8. The heat collecting device 7 is provided between the acrylic cover plate 4 and the light guiding device 8. The light guiding device 8 includes a light guiding tube 9, a gradually expanding tube 10 and a diffuser 11. The light guiding tube 9 is provided in the cavity 3. The gradually expanding tube 10 is connected to the light guiding tube 9. The gradually expanding tube 10 passes through the outer wall 2 of the underground space. The diffuser 11 is fixedly provided on the gradually expanding tube 10 on a side away from the light guiding tube 9. Through the provision of the light guiding device 8, the light guiding device 8 can reflect sunlight into the underground space 12.
[0023] A green plant device 13 is provided in the cavity 3, and is provided on the side of the cavity 3 opposite to the outer wall 2 of the underground space; a high reflective film 14 is provided in the cavity 3, and is provided on the outer surface of the soil 1 and the light guide 9. The provision of the green plant device 13 creates a physical barrier between the upper and lower air of the cavity 3, reduces the flow of air between the upper and lower parts of the cavity 3, and achieves the purpose of air circulation in the underground space 12.
[0024] The soil 1 is provided with an intercepting ditch 15, and two intercepting ditches 15 are provided, the two intercepting ditches 15 are respectively located on the upper surface of the cavity 3 and the soil 1, and the two intercepting ditches 15 are located below the acrylic cover plate 4. The provision of the intercepting ditch 15 can reduce the situation where the cavity 3 and the underground space 12 are flooded due to backflow of rainwater.
[0025] The outer wall 2 of the underground space is provided with a room air outlet 16 and a room air inlet 17, the room air outlet 16 is located above the room air inlet 17, and a window 18 is fixedly provided on the outer wall 2 of the underground space, the window 18 is located between the room air outlet 16 and the room air inlet 17; a dehumidifier 19 is provided in the room air inlet 17. The room air outlet 16 and the room air inlet 17 allow the underground space 12 to be ventilated with the cavity 3, promoting the air circulation of the underground space 12, and the dehumidifier 19 reduces the humidity entering the underground space 12, so that the air in the underground space 12 remains fresh.
[0026] The implementation principle of this embodiment is as follows: Figure 1 As shown, after the sunlight passes through the acrylic cover plate 4, it shines on the high-reflection film 14 on the outer side of the light pipe 9, and the reflected sunlight shines on the high-reflection film 14 on the soil 1. After the sunlight is reflected twice, it shines on the outer wall 2 of the underground space and shines into the room through the window 18; at the same time, the light pipe 9 collects the sunlight and makes the sunlight continuously reflected in the light pipe 9, and after passing through the gradually expanding tube 10 and the diffuser 11 in turn, the solar tube shines in the underground space 12 for supplementary lighting; the solar radiation passes through the acrylic cover plate 4 and enters the cavity 3, and the radiation is absorbed by the heat collecting device 7, and the heat collecting device 7 heats the air in the upper part of the cavity 3, so that the air density in the upper part of the cavity 3 is reduced, and flows to the outdoors through the outdoor vent 6, and the medium hot air in the underground space 12 flows to the cavity 3 through the room air outlet 16 to supplement the air in the upper part of the cavity 3, and the air in the lower part of the cavity 3 is subject to the pressure difference between the cavity 3 and the underground space 12, so that it passes through the dehumidification device 19 and flows to the underground space 12 for supplement.
[0027] By setting the acrylic cover plate 4, after the sunlight enters the cavity 3, it passes through the high-reflection film 14 and the light-guiding device 8 to enter the underground space 12 for lighting; by setting the heat collecting device 7, the heat collecting device 7 heats the air above the cavity 3, so that the air above the cavity 3 flows out from the outdoor vent 6, and the hot air in the underground space 12 flows to the cavity 3 from the room air outlet 16, while the air below the cavity 3 replenishes the underground space 12 through the room air inlet 17. The combination of the two makes full use of natural resources to illuminate and ventilate the underground space 12, which has the advantage of saving energy.
