Passive building energy conservation refers to energy-saving technology that reduces building energy consumption by means of non-mechanical electrical equipment intervention. Specifically, it refers to the reduction of heating, air conditioning, ventilation and other energy consumption required by the building through reasonable arrangement of building orientation, setting of sunshades, thermal insulation technology of building envelope structures, and design of building openings that are conducive to natural ventilation in building planning and design.

[0003] For example, Chinese patent CN209082759U, the utility model relates to a passive energy-saving wall, which includes a wall reinforced concrete structure, and an insulation layer, a structural layer, a supporting layer, a waterproof layer, a noise reduction layer and a roof panel are sequentially fixed on the outer side of the wall reinforced concrete structure. The passive energy-saving wall is easy to construct, and the installation between the structural layers is simple and firm.

[0004] The above patent still has certain defects. The wall construction of this patent is convenient, and the installation between the structural layers is simple and sturdy. High-rise buildings require a certain ventilation environment, which is mostly completed through windows, but the ventilation space of the windows is mostly closed in winter to prevent the outside cold air from pouring in.

[0034] The wall 2 is provided with a lifting groove for sliding connection between the lifting plate 101 and the spoiler 103. The cross section of the spoiler 103 is V-shaped. The V-shaped spoiler 103 prevents air from flowing directly into or out of the room after circulation.

A rotating hole for the auxiliary rod 108 to pass through is provided on the right side of the wall 2, and the auxiliary rod 108 is rotatably connected to the inside of the wall 2 through the rotating hole, so that when the auxiliary rod 108 is driven to rotate by the hand wheel 107, it can drive the take-up wheel 109 to rotate through the wall 2.

[0035] In this embodiment, the limiting assembly includes a connecting plate 104, a limiting spring 110 and a limiting block 111.

[0036] It should be noted that the baffle mechanism 1 fills the vents with evenly arranged baffles 103, so that the air cannot flow directly into or out of the room after circulation, thereby preventing cold air from quickly entering the room and lowering the indoor temperature in cold and windy weather, and also preventing the indoor air from quickly circulating outwards and losing heat.

[0037] See also Figure 4 In order to facilitate the staff to adjust the size of the vent, the ventilation mechanism 3 in this embodiment includes a sealing plate 301, a windshield plate 302, a threaded rod 303, a first gear 304, a first rotating rod 305, a second rotating rod 306, a second gear 307 and a handle 308. The first rotating rod 305 and the second rotating rod 306 are both rotatably connected to the top wall of the inner cavity of the wall 2. The top wall of the inner cavity of the wall 2 is provided with a second mounting groove and a third mounting groove. The second mounting groove and the third mounting groove are respectively fixed with a second bearing and a third bearing. The first rotating rod 30 5 is fixed inside the second bearing, the second rotating rod 306 is fixed inside the third bearing, the handle 308 is fixed to the bottom end of the second rotating rod 306, the second gear 307 is fixed to the outside of the second rotating rod 306, the first gear 304 is meshed with the outside of the second gear 307 and the first gear 304 is fixed to the outside of the first rotating rod 305, the threaded rod 303 is fixed to the bottom end of the first rotating rod 305, the sealing plate 301 and the wind shield plate 302 are both threadedly connected to the outside of the threaded rod 303, and a sealing gasket is fixed to the upper surface of the sealing plate 301.

[0038] In this embodiment, a vent is provided on the left side of the wall 2, and a receiving groove for sliding connection of the wind shield 302 is provided on the bottom wall of the inner cavity of the wall 2, so as to adjust the size of the vent opening and control the air circulation.

[0039] It should be noted that the ventilation mechanism 3 adjusts the size of the vent opening through the cooperation of the sealing plate 301, the wind shield plate 302, the threaded rod 303, the first gear 304, the first rotating rod 305, the second rotating rod 306, the second gear 307 and the handle 308, thereby controlling the air circulation amount, so that the user can adjust the air circulation amount according to weather conditions.

[0040] The working principle of the above embodiment is:

[0041] (1) When the air circulation rate needs to be slowed down, the hand wheel 107 is turned. The hand wheel 107 drives the take-up wheel 109 to rotate through the auxiliary rod 108, and at the same time releases the wire rope 106 downward. While the wire rope 106 extends downward, the baffle plate 103 falls downward and drives the lifting plate 101 to move downward together through the connecting plate 104, and straightens the wire rope 106. At the same time, the slider 105 moves downward together with the lifting plate 101 until the slider 105 slides down to the bottom of the limit groove and then stops turning the hand wheel 107. At this time, the evenly arranged baffle plates 103 fill the vents to block the air flowing through, making it difficult for the air to flow smoothly and quickly in a straight line. The baffle mechanism 1 fills the vents with the evenly arranged baffle plates 103, so that the air cannot flow directly into the room or out of the room after circulation, thereby preventing the cold air from quickly entering the room in cold and windy weather to lower the indoor temperature, and also preventing the indoor air from quickly circulating outward and losing heat.

[0042] (2) When the size of the vent needs to be adjusted, the spoiler 103 is raised, and then the handle 308 is rotated. The handle 308 drives the second gear 307 to rotate through the second rotating rod 306. The first gear 304 drives the first rotating rod 305 to rotate while the second gear 307 rotates. At the same time, the first rotating rod 305 drives the threaded rod 303 to rotate together. The sealing plate 301 and the wind shield plate 302 move downward and shrink to the inside of the storage hole as the threaded rod 303 rotates, thereby gradually opening the vent. When the vent is opened to a suitable size, the handle 308 can be stopped from being rotated. The ventilation mechanism 3 adjusts the size of the vent opening through the cooperation of the sealing plate 301, the wind shield plate 302, the threaded rod 303, the first gear 304, the first rotating rod 305, the second rotating rod 306, the second gear 307 and the handle 308, thereby controlling the air circulation, so that the user can adjust the air circulation size according to weather conditions.
