[0002] Green building is a kind of building design and construction method based on the concept of environmental protection and sustainable development. It aims to reduce the adverse impact on the environment, improve the energy efficiency of buildings, and improve the quality of living and working environment. The design and implementation of green buildings usually consider the following aspects: resource utilization, energy conservation and emission reduction, water resource management, indoor environmental quality, health and well-being. Green building not only helps to protect the environment and sustainable development, but also brings economic and social benefits to the users of the building. It can reduce the cost of energy and water resources, improve indoor air quality, and improve the productivity and health of employees.

[0003] In the prior art, the ventilation and drainage systems of green buildings are generally designed in a resource recycling manner. However, the buildings of this design are often connected to water tanks for collecting water, which makes it easy for moisture to return indoors and the humidity is too high, causing moss to grow on the walls. In addition, the ventilation system will increase the distribution of water molecules in the air. When cold and hot air currents convect, it is easy to cause a situation like the "return of the south wind" in the south, and it is impossible to effectively control the dryness and wetness of the indoor air.

DETAILED DESCRIPTION

[0031] like Figure 1-7As shown, a green building ventilation and drainage device comprises a collection pool 1 and a storage pool 2 installed on the green building, wherein the collection pool 1 is connected to the top of the storage pool 2, and a ventilation duct 3 is also connected to the side of the storage pool 2, and the other end of the ventilation duct 3 is connected to the green building. The present invention is applied to the green building, and its main purpose is to allow the green building to have the functions of water storage, quantitative drainage, ventilation and humidity control in the green building. In the present invention, raindrops are mainly collected by the collection pool 1, and the raindrops are allowed to converge into the storage pool 2 for storage.

[0032] In order to expand the air flow outside the green building, a vent 21 is respectively provided on both sides of the inner end of the storage pool 2 in the present invention, and the storage pool 2 is connected to the ventilation duct 3 through the vent 21, and a blade stick 22 is also provided in the storage pool 2, the blade stick 22 and the vent 21 are at the same height, the storage pool 2 is connected to the collection pool 1 through the connecting port 28, the blade stick 22 is staggered from the connecting port 28, but the blades of the blade stick 22 extend to the bottom of the connecting port 28; through such a setting, when the airflow outside the storage pool 2 flows, it will flow into the storage pool 2 along the vent 21, and flow into the ventilation duct 3 through another vent 21, and finally flow into the green building through the ventilation duct 3, and the water falling down along the collection pool 1 will also hit the blades on the surface of the blade stick 22, so that the blade stick 22 rotates and drives the airflow, and because the blade stick 22 is staggered from the connecting port 28, the blade stick 22 will not rotate in a different direction due to the impact of water drops;

[0033] Both ends of the blade rod 22 pass through the outside of the storage pool 2, and a pair of rollers 221 are respectively provided at both ends of the blade rod 22. The purpose of providing the pair of rollers 221 is to allow the airflow outside the storage pool 2 to drive the pair of rollers 221 to rotate, and the rotation of the blade rod 22 drives the airflow to flow toward the ventilation duct 3, thereby flowing into the green building to maintain the ventilation effect.

[0034] As shown in the figure, the lower end surface of the storage pool 2 is inclined, and the lower end is connected to a filter tube 23, and the filter tube 23 is connected to the input end of a water pump 24, and the output end of the water pump 24 is connected to the top of the storage pool 2. Through this design, the water in the storage pool 2 can be pumped by the water pump 24 to flow without forming dead water, thereby improving the activity of water;

[0035] At the same time, a water level detector 25 for detecting the water level is provided on the inner side of the storage pool 2. When the water level spreads to the water level detector 25, the water level detector 25 will transmit an electrical signal to the water pump 24 and control the water pump 24 to pump the water upward. Through such a setting, the problem of starting the water pump 24 when there is only part of the water in the storage pool 2 can be effectively avoided, which can effectively save energy and avoid the life of the water pump 24 due to long-term work. It is worth noting that the filter tube 23, the water pump 24, and the water level detector 25 are all existing technologies and are not described in detail in this article.

[0036] Furthermore, the inner end of the storage pool 2 is connected to the outside through an overflow port 26 near the ventilation port 21, and a baffle 27 inclined upward is provided near the overflow port 26 of the storage pool 2. This is arranged to limit and raise the amount of stored water through the baffle 27, while also preventing dust outside the storage pool 2 from flowing into the storage pool 2, and a ventilation filter layer for intercepting impurities is also provided in the ventilation port 21.

[0037] Furthermore, in order to be able to adjust the dryness and humidity in the green building, the ventilation duct 3 in the present invention is provided with a plurality of adjustment groups, each of which includes a first air guide block 31, a second air guide block 32, and a closing member 33. The closing member 33 is located between the first air guide block 31 and the second air guide block 32. The first air guide block 31 and the second air guide block 32 both have an arc-shaped surface, and the arc-shaped surfaces of the two are staggered. This arrangement is to close the passage between the first air guide block 31 and the second air guide block 32 through the closing member 33, and the opening and closing of the passage plays a key role in the humidity in the green building. The ventilation duct 3 in the invention also includes a cylinder 34, and a connecting rod 341 is provided on the output shaft of the cylinder 34. The connecting rod 341 is rotatably connected to each closing member 33 through each rotating shaft 332 that penetrates the ventilation duct 3, so that each closing member 33 can be controlled to move forward and backward by the cylinder 34. Therefore, when it is necessary to change the humidity in the green building, all windows, doors and other gaps in the green building where gas can flow can be closed, and then the cylinder 34 is used to control the expansion and contraction of the connecting rod 341, thereby driving the closing member 33 to move, so that the closing member 33 closes the passage between the first air guide block 31 and the second air guide block 32;

[0038] Furthermore, the upper and lower ends of the closing piece 33 extend to the surfaces of the first air guide block 31 and the second air guide block 32 respectively, and the upper and lower ends of the side of the closing piece 33 are respectively provided with inwardly recessed deformation abutment blocks 331, and the first air guide block 31 and the second air guide block 32 are abutted against the surface of the deformation abutment block 331; and the deformation abutment block 331 is made of rubber material. When the connecting rod 341 pushes the closing piece 33 to move, the connecting rod 341 will be squeezed and deformed, so that it is tightly attached to the surfaces of the first air guide block 31 and the second air guide block 32.

[0039] In addition, a first slide groove 333 is respectively provided on the left and right sides of the closing member 33, and a slide shaft 334 is slidably provided in each first slide groove 333, and a corresponding second slide groove 35 is provided on the inner side of the ventilation duct 3, and the slide shaft 334 extends into the second slide groove 35, and the first slide groove 333 extends in the length direction of the closing member 33, and the middle part to the end of the second slide groove 35 is bent downward; the lower end of the second slide groove 35 is at the same horizontal height as the lower end of the rotating shaft 332, so that when the slide shaft 334 moves to the downwardly inclined end of the second slide groove 35, the closing member 33 swings to be parallel to the horizontal plane, and this arrangement is for When the closing piece 33 is pushed laterally, the closing piece 33 is allowed to gradually swing parallel to the horizontal plane during the pushing process. Such a setting can increase the flow rate of gas compared to when the closing piece 33 does not swing. If the closing piece 33 does not rest against the surfaces of the first air guide block 31 and the second air guide block 32 and does not swing, the airflow blown toward the closing piece 33 will flow to the upper and lower sides again, thereby slowing down the flow rate of the airflow, making it difficult for the airflow to flow into the green building. In addition, if a single end of the closing piece 33 is swung open, the direction of the airflow will also be changed, causing the airflow to move upward or downward, impacting the inner end surface of the ventilation duct 3, which will also affect the flow rate of the airflow.

[0040] In addition, the surface of the collection pool 1 has a groove for receiving rainwater, and a bracket 11, a filter plate 12 and a filter layer 13 are installed in the groove. The filter plate 12 is covered on the upper end of the bracket 11, and the inner ends of the bracket 11 are raised in a step-like shape from both sides to the middle, and the filter layer 13 is arranged between the bracket 11 and the collection pool 1, and also has a corresponding surface, and the outer edge of the filter plate 12 extends over the inner edge of the groove.

[0041] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of the present invention. That is, equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification should still fall within the scope of the present invention.
