Description

Technical Field

[0001] This application relates to the field of building ventilation technology, and in particular to a low-carbon and energy-saving concealed ventilation structure for high-rise buildings. Background Technology

[0002] As the exterior wall cladding structure of modern large and high-rise buildings, curtain walls have become the mainstream choice due to their lightweight and aesthetically pleasing characteristics. One of their core functions is to block direct sunlight and reduce the direct transmission of solar radiation into the interior. However, in low-latitude regions, the summer sunshine hours are long and the radiation intensity is high. Although curtain walls can block direct sunlight from hitting the main building, they themselves will continuously absorb solar radiation energy, causing the surface and interior temperatures to rise rapidly. The curtain wall will continuously transfer the accumulated heat into the building interior through heat conduction and heat convection, raising the indoor temperature. This will force the building's cooling system to operate at high load for a long time, which will not only increase energy consumption but also significantly reduce cooling efficiency, making it difficult to meet the building's low-carbon and energy-saving usage requirements.

[0003] According to a search, patent document CN217811777U discloses a double-layer breathing energy-saving curtain wall, including a curtain wall panel with a cavity. The curtain wall panel has an inner side wall, an outer side wall, a top wall, a bottom wall, and two vertical side walls. The inner side wall of the curtain wall panel faces the interior, and the two vertical side walls of the curtain wall panel are respectively provided with ventilation holes facing horizontally. In this application, the cavity of the curtain wall panel can form an air passage with the outer space of the curtain wall panel, which is beneficial to accelerate the heat dissipation of the curtain wall panel and reduce the problem of the curtain wall affecting the building's cooling efficiency.

[0004] The aforementioned comparative documents also have the following shortcomings: The water inlet holes in the aforementioned comparative documents are located at the top of the curtain wall panel. Due to the installation of the curtain wall panels, the bottom of the upper curtain wall panel will block the water inlet holes at the top of the lower curtain wall panel. This installation layout will block the rainwater's path, and most of the rainwater will be intercepted by the upper curtain wall panel. Only a very small portion can fall into the water inlet holes, resulting in extremely low rainwater collection efficiency. It is difficult to effectively replenish the moisture in the cavity, and the heat dissipation function in the cavity that relies on water evaporation cannot be stably performed, thus weakening the heat dissipation effect. Utility Model Content

[0005] To overcome the above-mentioned shortcomings, this application provides a low-carbon and energy-saving concealed ventilation structure for high-rise buildings, which solves the problems existing in the prior art.

[0006] To achieve the above objectives, this application provides the following technical solution: a low-carbon and energy-saving concealed ventilation structure for high-rise buildings, comprising a back panel, a cover fixedly connected to one side of the back panel, an opening on one side of the cover, a rotating shaft rotatably connected inside the opening, a water replenishment component mounted on the rotating shaft, a connecting strip fixedly connected to one side of the cover, a scraper fixedly connected to the bottom of the connecting strip, a first guide plate fixedly connected to the inner wall of the cover, a plurality of second guide plates and a plurality of L-shaped water-retaining baffles fixedly connected to the inner wall of the cover, and a plurality of absorbent cotton pads mounted on one side of the back panel.

[0007] Preferably, the water replenishment component includes a fan-shaped water tank, which is coaxially and fixedly connected to the rotating shaft. The fan-shaped water tank has a water inlet and a water outlet, respectively. A filter screen is installed in the water inlet. A baffle is fixedly connected to the fan-shaped water tank, and a counterweight is fixedly connected to one side of the fan-shaped water tank.

[0008] Preferably, a limit rod is fixedly connected to the inner wall of the cover.

[0009] Preferably, multiple sets of ventilation holes are provided on both sides of the cover.

[0010] Preferably, a water outlet is provided on one side of the cover.

[0011] Preferably, the L-shaped water storage baffle has an overflow notch.

[0012] Preferably, one side of the L-shaped water storage baffle is fixedly connected to the back plate.

[0013] Compared with the prior art, the beneficial effects of this application are as follows: This application includes a cover, a rotating shaft, a water supply component, and a scraper. The water supply component is located in an opening on one side of the cover to prevent obstruction by the upper curtain wall. When a certain amount of rainwater accumulates in the water supply component, the component rotates via the rotating shaft to pour the rainwater into the cover. Afterward, the water supply component automatically resets, ensuring continuous circulation and collection of rainwater. While the water supply component is rotating, the scraper can scrape off impurities from the filter screen of the water supply component, preventing impurities from clogging the filter screen, reducing maintenance requirements, and enhancing the stability and durability of the ventilation structure of high-rise buildings under complex working conditions.

Detailed Implementation

[0016] The technical solution of this application will be further described in detail below with reference to specific embodiments.

[0017] like Figures 1-6 As shown, this application provides a technical solution: A low-carbon and energy-saving concealed ventilation structure for high-rise buildings includes a back panel 1, a cover 2 fixedly connected to one side of the back panel 1, an opening on one side of the cover 2, a rotating shaft 3 rotatably connected inside the opening, a water replenishment component on the rotating shaft 3, a connecting strip 4 fixedly connected to one side of the cover 2, a scraper 5 fixedly connected to the bottom of the connecting strip 4, a first guide plate 6 fixedly connected to the inner wall of the cover 2, multiple second guide plates 7 and multiple L-shaped water storage baffles 8 fixedly connected to the inner wall of the cover 2, a limit rod 14 fixedly connected to the inner wall of the cover 2, a water outlet 16 opened on one side of the cover 2, an overflow notch 17 opened on the L-shaped water storage baffle 8, and one side of the L-shaped water storage baffle 8 fixedly connected to the back panel 1. Specifically, the water replenishment component is installed inside an opening on one side of the cover 2 to prevent obstruction by the upper curtain wall. When a certain amount of rainwater accumulates in the water replenishment component, it rotates via the pivot 3 until it is stopped by the limit rod 14, allowing the rainwater to flow into the cover 2. Afterward, the water replenishment component automatically resets, ensuring continuous circulation and collection of rainwater. As the water replenishment component rotates, the scraper 5 can scrape off impurities from the component, preventing blockages, reducing maintenance requirements, and enhancing the ventilation structure of high-rise buildings under complex conditions. Stability and durability: Rainwater in the water replenishment component is poured onto the first guide plate 6, then flows along the first guide plate 6 to the second guide plate 7, and then flows through the second guide plate 7 into the L-shaped water storage baffle 8. The L-shaped water storage baffle 8, the back plate 1, and the cover 2 enclose a water storage tank. When the L-shaped water storage baffle 8 is full of rainwater, the excess rainwater flows through the overflow gap 17 to the next second guide plate 7, and then to the next L-shaped water storage baffle 8. When multiple L-shaped water storage baffles 8 are full, the rainwater is discharged through the outlet 16. The water replenishment component includes a fan-shaped water tank 10, which is coaxially and fixedly connected to the rotating shaft 3. The fan-shaped water tank 10 is provided with a water inlet and a water outlet. A filter screen 11 is installed in the water inlet. A baffle 12 is fixedly connected to the fan-shaped water tank 10. A counterweight block 13 is fixedly connected to one side of the fan-shaped water tank 10. Specifically, when there is no rainwater in the fan-shaped water tank 10, the counterweight 13 generates torque by its own weight, causing the baffle 12 to be tightly attached to the inner wall of the cover 2. After the rainwater is filtered through the filter screen 11, it enters the fan-shaped water tank 10. When the rainwater in the fan-shaped water tank 10 accumulates to a certain amount, the torque generated by the gravity of the rainwater exceeds the balance torque of the counterweight 13, driving the fan-shaped water tank 10 to rotate through the rotating shaft 3. The water outlet then turns to the inside of the cover 2, pouring all the filtered rainwater into the cover 2. After the rainwater is emptied, the torque of the counterweight 13 takes over again, causing the fan-shaped water tank 10 to rotate in the opposite direction and reset. Multiple absorbent cotton pads 9 are provided on one side of the back panel 1, and multiple sets of ventilation holes 15 are provided on both sides of the cover 2. Specifically, after the absorbent cotton pad 9 is soaked and dried in a nano-silver solution, its internal interconnected pores are uniformly filled with nano-silver particles with a particle size of 50-100nm. This structure can effectively inhibit the growth of bacteria and mold on the surface of the damp cotton pad, preventing the absorbent cotton pad 9 from becoming moldy and developing odors due to long-term contact with rainwater, thus ensuring the cleanliness and durability of the structure for long-term use. The multiple sets of ventilation holes 15 opened on both sides of the cover 2 can form a through-flow air circulation channel. When natural wind forms a convective airflow through the ventilation holes 15 on both sides of the cover 2, the airflow will continuously flow over the surface and surrounding area of ​​the absorbent cotton pad 9. At this time, the rainwater absorbed and stored in the absorbent cotton pad 9 comes into full contact with the flowing airflow. The disturbance effect of the airflow significantly accelerates the evaporation of water. The evaporation process will quickly absorb a large amount of heat from the surrounding environment, reducing the temperature inside the cover 2. This not only removes the heat from the curtain wall structure itself, but also indirectly cools the interior of the building, ultimately achieving the dual effects of efficient heat dissipation and low-carbon energy saving.

[0018] The working principle of this application is as follows: When there is no rainwater in the fan-shaped water tank 10, the counterweight 13 generates torque by its own weight, causing the baffle 12 to be tightly attached to the inner wall of the cover 2, so that the water inlet is on one side of the cover 2, preventing the upper curtain wall from blocking it. After the rainwater is filtered by the filter screen 11, it enters the fan-shaped water tank 10. When the rainwater in the fan-shaped water tank 10 accumulates to a certain amount, the torque generated by the gravity of the rainwater exceeds the balance torque of the counterweight 13, driving the fan-shaped water tank 10 to rotate through the rotating shaft 3 until it is blocked by the limit rod 14. The water outlet then turns to the inside of the cover 2, pouring all the filtered rainwater into the cover 2. After the rainwater is emptied, the torque of the counterweight 13 takes over again, causing the fan-shaped water tank 10 to rotate in the opposite direction and reset. When the fan-shaped water tank 10 rotates, the scraper 5 can scrape off the impurities on the filter screen 11, avoiding impurity blockage, reducing maintenance needs, and enhancing the stability and durability of the ventilation structure of high-rise buildings under complex working conditions. Rainwater in the water replenishment component is poured onto the first guide plate 6, then flows along the first guide plate 6 to the second guide plate 7, and then flows through the second guide plate 7 into the L-shaped water storage baffle 8. The L-shaped water storage baffle 8, the back plate 1, and the cover 2 enclose a water storage tank. When the L-shaped water storage baffle 8 is full of rainwater, the excess rainwater flows through the overflow gap 17 to the next second guide plate 7, and then to the next L-shaped water storage baffle 8. When multiple L-shaped water storage baffles 8 are full, the rainwater is discharged through the outlet 16. After being soaked and dried in a nano-silver solution, the absorbent pad 9 has nano-silver particles with a diameter of 50-100nm uniformly filling its interconnected pores. This structure can effectively inhibit the growth of bacteria and mold on the surface of the damp pad, preventing the absorbent pad 9 from becoming moldy and developing odors due to long-term contact with rainwater, thus ensuring the cleanliness and durability of the structure for long-term use. The multiple sets of ventilation holes 15 on both sides of the cover 2 can form a through-flow air circulation channel. When natural wind forms a convective airflow through the ventilation holes 15 on both sides of the cover 2, the airflow will continuously flow over the surface and surrounding area of ​​the absorbent pad 9. At this time, the rainwater absorbed and stored in the absorbent pad 9 comes into full contact with the flowing airflow. The disturbance effect of the airflow significantly accelerates the evaporation of water. The evaporation process will quickly absorb a large amount of heat from the surrounding environment, reducing the temperature inside the cover 2. This not only removes the heat from the curtain wall structure itself, but also indirectly cools the interior of the building, ultimately achieving the dual effects of efficient heat dissipation and low-carbon energy saving.
