Technical Field

[0001] The utility model relates to the technical field of green ecological building energy saving, in particular to a green ecological building design energy saving device. Background Art

[0002] Green ecological building refers to the building that consumes the least earth resources, uses the least energy and produces the least waste during the building life cycle (referring to a series of processes from building materials production to building planning and design, construction, use, management and demolition). One of the ways to consume earth resources is energy conservation.

[0003] An energy-saving device designed for a green ecological building in the prior art, with the publication number CN219775929U. When in use, the outside wind drives the ventilation fan to rotate, thereby ventilating the interior of the green ecological building through the ventilation pipe. At the same time, the filter screen filters dust from the air entering the ventilation pipe. After the filter screen has been used for a long time, the screw can be screwed to remove the upper fixing rod, and then a new filter screen can be replaced, and the new filter screen is engaged in the first engaging groove on the lower fixing rod, and then the upper fixing rod is placed on the filter screen, and the upper end of the filter screen is also engaged in the first engaging groove, and then the upper fixing rod is fixedly installed on the ventilation pipe by screws, thereby ensuring the filtering efficiency of the filter screen.

[0004] However, the filter of the prior art needs to be replaced manually, but the frequency of filter replacement depends on the amount of dust in the air. Therefore, when there is more dust in the air, the frequency of filter replacement will increase. Moreover, during the process of replacing the filter, the ventilation pipe is in a state where it cannot be filtered, so the dust in the air will enter the building. Utility Model Content

When the filter 6 at the pipe opening of the ventilation pipe 2 is blocked, the filter 6 blocked at the air inlet of the ventilation pipe 2 can be pulled out by pulling the filter 6, and the dust cover 3 provided can ensure that the surface of the part of the filter 6 wound on the reel 11 will not be exposed to the air, causing dust to adhere to the surface of the part of the filter 6. A brush 8 for cleaning the dust on the surface of the filter 6 is inserted at the cover opening of the outer wall of the dust cover 3, and the bottom end of the reel 11 extends outward through the fixed frame 12 and is arranged in the shape of a belt pulley driven by a belt, as shown in FIG. Figure 2 As shown, a belt is used to connect the bottom ends of the two reels 11 to ensure that when one of the reels 11 rotates, the other reel 11 is driven to rotate, and the brush 8 provided can clean the dust on the surface of the filter 6 before the filter 6 enters the corresponding dust cover 3.

[0025] In order to drive the brush 8 to move up and down and clean the dust on the front side of the filter 6: the top of the reel 11 passes through the fixed frame 12 and extends outward to be fixedly connected to the main bevel gear 7, and the fixed frame 12 is rotatably connected to a slave bevel gear 10 meshing with the main bevel gear 7, and the end edge of the slave bevel gear 10 is rotatably connected to a connecting handle 9, and the other end of the connecting handle 9 is rotatably connected to one end of the brush handle of the brush 8, and a motor 16 for driving one of the main bevel gears 7 to rotate is fixedly connected to the fixed frame 12, and the fixed frame 12 and one end of the brush handle of the brush 8 are movably connected through a spring rod, and the motor 16 is used to drive the corresponding main bevel gear 7 to rotate, thereby realizing the rotation of one of the reels 11 at the corresponding position, and under the connection action of the belt, another reel 11 drives another main bevel gear 7 to rotate, and when the main bevel gear 7 rotates, the slave bevel gear 10 can be rotated, and under the connection action of the spring rod and the connecting handle 9, the brush 8 can be reciprocated up and down with the rotation of the slave bevel gear 10.

[0026] In order to adjust the direction of the ventilation duct 2 according to the wind direction: a guide plate 4 is fixedly connected to the top edge of the outer wall of the ventilation duct 2, the outer wall of the guide plate 4 is covered with a solar panel, and a transformer and a battery are built into the guide plate 4. The battery stores the electricity generated by light energy, and the stored electricity is regularly used to drive the motor 16 and the electric push rod 13. The guide plate 4 is hollow and the outer wall is an isosceles triangle. The isosceles triangle arrangement ensures that when the wind direction changes, the airflow blows on the side of the guide plate 4, and through the isosceles triangle arrangement on its side, the ventilation duct 2 swings until the tip of the guide plate 2 is aligned with the wind direction. At this time, the air inlet of the ventilation duct 2 faces the air outlet, and the airflow can enter the ventilation duct 2 through the filter 6, and then enter the room For ventilation, the ventilation pipe 2 is rotatably connected to the building wall 1, and a brake disc 15 is fixedly connected to the bottom edge of the outer tube wall of the ventilation pipe 2, an electric push rod 13 is fixedly connected to the building wall 1, and a brake pad 14 for rubbing against the brake disc 15 is fixedly connected to the telescopic end of the electric push rod 13, and a dustproof ring 5 for surrounding the electric push rod 13, the brake pad 14 and the brake disc 15 is also fixedly connected to the building wall 1, and the top of the dustproof ring 5 is rotatably connected to the bottom edge of the outer tube wall of the ventilation pipe 2. After the air inlet of the ventilation pipe 2 is aligned with the air outlet, the brake pad 14 is pressed against the brake disc 15 by extending the electric push rod 13, and the position of the ventilation pipe 2 is fixed by fixing the position of the brake disc 15, that is, the ventilation pipe 2 is prevented from swinging when the wind direction changes slightly.

[0027] Working principle: when the filter needs to be replaced, the motor 16 is used to drive the corresponding main bevel gear 7 to rotate, so as to realize the rotation of one of the reels 11 at the corresponding position. Under the connection of the belt, the other reel 11 drives the other main bevel gear 7 to rotate. When the main bevel gear 7 rotates, the slave bevel gear 10 can be rotated. Under the connection of the spring rod and the connecting handle 9, the brush 8 can be reciprocated up and down with the rotation of the slave bevel gear 10. When the two reels 11 rotate, the filter 6 is pulled so that the other part of the filter 6 covers the air inlet of the ventilation pipe 2, and the dust on the surface of the filter 6 entering the dust cover 3 is cleaned by the brush 8.
