Description

Technical Field

[0001] The utility model relates to the technical field of building ventilation, in particular to an energy-saving ventilation structure for building design. Background Art

[0002] Architectural design means that before a building is constructed, the designer, in accordance with the construction task, makes a comprehensive conception of the problems that exist or may occur during the construction process and use, formulates solutions and plans to solve these problems, and expresses them in drawings and documents as a common basis for material preparation, construction organization and the cooperation of various types of work in the production and construction work.

[0003] A patent with the announcement number CN116447737A discloses an energy-saving ventilation structure for architectural design, comprising a hood body, the hood body including curved blades and a central axis, the hood body rotatably connected to an exhaust duct, the bottom end of the exhaust duct fixedly connected to a base, the exhaust duct having a built-in lifting mechanism, the lifting mechanism used to connect and close the exhaust duct, the lifting mechanism including a slide rail, the slide rail being fixedly connected to a movable frame by bolts, the inner side of the slide rail being slidably connected to a support block, and the fresh air system is an independent air treatment system consisting of an air supply system and an exhaust system, which is divided into two types: ducted fresh air systems and non-ducted fresh air systems. Fresh air systems are generally used for ventilation in buildings, but using fresh air systems requires electricity. If a non-powered hood is used for ventilation, although it does not require electricity, when the external air quality is poor, such as in haze, polluted air can easily enter the room, causing indoor air pollution.

[0004] Existing factories generally install hoods on the roof of the factory for main ventilation and heat dissipation. However, the iron roof will produce a large amount of high-temperature gas under the sun, and the hood is to guide the natural air from the outside into the interior of the factory, and mix the low-temperature air from the outside with the high-temperature air inside the factory to cool the factory. However, the cooling speed of this method is relatively slow, and the amount of low-temperature gas from the outside entering the factory is relatively small. The efficiency and range of mixed cooling are relatively narrow and slow, and it can only cool the high-temperature gas around the iron tiles. Some high-temperature heat sources far away from the iron tiles cannot be effectively cooled. Utility Model Content

[0005] To this end, the technical problem to be solved by the present invention is to overcome the problem in the existing technology that the high-temperature air flow away from the iron tiles is poor, the heat dissipation efficiency cannot keep up with the heat dissipation speed of the iron tiles under high temperature exposure, and thus additional high-temperature gas cannot be used for effective cooling.

[0006] In order to solve the above technical problems, the utility model provides an energy-saving ventilation structure for building design, including an iron tile and a limiting ring arranged on the outer surface of the top of the iron tile, a support bar fixedly installed at the top edge position of the iron tile and the bottom surface of the limiting ring, an auxiliary iron tile is arranged on the top surface of the iron tile, and a heat dissipation gap is arranged between the iron tile and the auxiliary iron tile; a protective top is movably sleeved on the outer surface of the top of the auxiliary iron tile, and guide fan blades are fixedly installed on the outer surface of the protective top and at the top edge position of the auxiliary iron tile, and push fan blades are fixedly connected to the bottom edge position and the middle position of the protective top.

[0007] In one embodiment of the present invention, a limited guide plate is provided at the top edge of the iron tile and between the two groups of pushing blades.

[0008] In one embodiment of the present invention, supporting crossbeams are fixedly installed on the inner wall surface and the two side edges of the top of the iron tile.

[0009] In one embodiment of the present invention, the other end of the supporting beam on the top surface of the iron tile is fixedly mounted on the bottom inner wall of the auxiliary iron tile, and one end of the support bar is fixedly mounted on the inner wall of the auxiliary iron tile.

[0010] In one embodiment of the present invention, a drainage funnel is fixedly connected to the other end of the support bar and is movably sleeved on the outer surface of the protective top.

[0011] In one embodiment of the present invention, the bottom edge of the drainage funnel is arranged at the top edge of the limiting drainage plate.

[0012] In one embodiment of the present invention, the surface position of the limiting ring is set at the middle position of the top of the auxiliary iron tile, and an air guide strip is fixedly connected to the inner wall surface of the limiting ring, and the other end of the air guide strip is movably connected to the outer surface of the auxiliary iron tile.

[0013] In one embodiment of the present invention, a lateral drainage strip that is movably mounted on the bottom edge of the drainage funnel is fixedly installed on the top surface of the iron tile and the limiting drainage plate, and a drainage chute is provided on the inner wall surface of the lateral drainage strip.

[0014] The above technical solution of the utility model has the following advantages compared with the prior art:

[0015] The energy-saving ventilation structure for building design described in the present invention utilizes the heat dissipation gap between the iron sheet tiles and the auxiliary iron sheet tiles to increase the heat dissipation path of the iron sheet tiles and the auxiliary iron sheet tiles themselves under the sun exposure, and at the same time cooperates with the inclined surfaces on the outer surfaces of the iron sheet tiles and the auxiliary iron sheet tiles so that when the gas contacts the top surface of the iron sheet tiles and the auxiliary iron sheet tiles, the inclined surfaces of the iron sheet tiles and the auxiliary iron sheet tiles are used to change the flow path and flow direction of the external gas, and the gas in the changed path will be mixed with the gas at other positions. Under the condition that the distance and gas flow rate remain unchanged, the flow of the gas is changed. The dynamic path will speed up the flow of gas, so that the low-temperature gas outside will quickly pass through the heat dissipation gap between the iron tile and the auxiliary iron tile along the inclined surface of the iron tile, and be quickly discharged from the heat dissipation gap on the other side of the iron tile and the auxiliary iron tile along the path. Low pressure will be formed around the fast-flowing gas, and then the normal gas around it will flow quickly towards the low pressure. Then the fast-flowing low pressure will carry the high-temperature hot air to flow quickly to the outside, so that the high-temperature gas accumulated at the top edge of the iron tile will be quickly discharged.

[0016] The utility model describes an energy-saving ventilation structure for architectural design. When the flowing gas passes through the heat dissipation gap and the top surface of the auxiliary iron tile, the fast-flowing airflow will push the guide blades on the outer surface of the auxiliary iron tile, so that the protective top rotates with the limiting ring as the center, thereby driving the pushing blades at the bottom end of the protective top to rotate together, and the inclined surface on the pushing blade surface generates an upward driving force during rotation, which accelerates the rapid flow of the heat source around the inner side surface of the top of the iron tile, and at the same time drives the high-temperature airflow farther away from the inner cavity of the iron tile to flow rapidly, thereby quickly discharging the airflow.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0026] Reference Figure 1 - Figure 6 As shown, the utility model is an energy-saving ventilation structure for building design, including a metal tile 11 and a limiting collar 12 provided on the top outer surface of the metal tile 11, a support bar 13 fixedly installed at the top edge position of the metal tile 11 and the bottom surface of the limiting collar 12, an auxiliary metal tile 112 is provided on the top surface of the metal tile 11, and a heat dissipation gap is provided between the metal tile 11 and the auxiliary metal tile 112; a protective top 122 is movably sleeved on the top outer surface of the auxiliary metal tile 112, and guide blades 123 are fixedly installed on the outer surface of the protective top 122 and at the top edge position of the auxiliary metal tile 112, and push blades 124 are fixedly connected to the bottom edge position and the middle position of the protective top 122.

[0027] The heat dissipation gap between the iron sheet tile 11 and the auxiliary iron sheet tile 112 is used to increase the heat dissipation path of the iron sheet tile 11 and the auxiliary iron sheet tile 112 under the sun exposure. At the same time, the inclined surface on the outer surface of the iron sheet tile 11 and the auxiliary iron sheet tile 112 is used to change the flow path and flow direction of the external gas when the gas contacts the top surface of the iron sheet tile 11 and the auxiliary iron sheet tile 112. The gas that changes the path will mix with the gas at other positions. When the distance and gas flow remain unchanged, changing the flow path of the gas will speed up the process. The flow rate of the gas causes the low-temperature gas from the outside to quickly pass through the heat dissipation gap between the iron tile 11 and the auxiliary iron tile 112 along the inclined surface of the iron tile 11, and be quickly discharged from the heat dissipation gap on the other side of the iron tile 11 and the auxiliary iron tile 112 along the path. Low pressure is formed around the fast-flowing gas, which causes the normal surrounding gas to flow quickly in the direction of low pressure. The fast-flowing low pressure will then carry the high-temperature hot gas to flow quickly to the outside, thereby quickly discharging the high-temperature gas accumulated at the top edge of the iron tile 11.

[0028] When the flowing gas passes through the heat dissipation gap and the top surface of the auxiliary iron tile 112, the fast-flowing airflow will push the guide blades 123 on the outer surface of the auxiliary iron tile 112, causing the protective top 122 to rotate with the limiting ring 12 as the center, thereby driving the pushing blades 124 at the bottom end of the protective top 122 to rotate together, and the inclined surface on the surface of the pushing blades 124 generates an upward driving force during rotation, accelerating the rapid flow of the heat source around the inner side surface of the top of the iron tile 11, and at the same time driving the high-temperature airflow farther away from the inner cavity of the iron tile 11 to flow rapidly, thereby quickly discharging the airflow.

[0029] Reference Figure 1 - Figure 6As shown, in one embodiment of the present invention, a limited drainage plate is provided at the top edge of the iron tile 11 and between the two groups of pushing blades 124, and a supporting crossbeam 111 is fixedly installed on the inner wall surface and the two side edges of the top of the iron tile 11, and the other end of the supporting crossbeam 111 on the top surface of the iron tile 11 is fixedly installed on the bottom inner wall surface of the auxiliary iron tile 112, one end of the support bar 13 is fixedly installed on the inner wall surface of the auxiliary iron tile 112, and the other end of the support bar 13 is fixedly connected to a drainage device movably sleeved on the outer surface of the protective top 122. Funnel 131, the bottom edge position of the drainage funnel 131 is set at the top edge position of the limiting drainage plate, the surface position of the limiting ring 12 is set at the middle position of the top of the auxiliary iron tile 112, and the inner wall surface of the limiting ring 12 is fixedly connected with the wind guide oblique strip 121, and the other end of the wind guide oblique strip 121 is movably connected to the outer surface of the auxiliary iron tile 112. The iron tile 11 and the top surface of the limiting drainage plate are fixedly installed with a lateral drainage strip 113 that is movably connected to the bottom edge position of the drainage funnel 131, and a drainage inclined groove is provided on the inner wall surface of the lateral drainage strip 113.

[0030] Under the push of the fan blades 124, a part of the air flow will pass through the iron tile 11 and enter the interior of the drainage funnel 131. The drainage funnel 131 is small at the top and large at the bottom to compress the gas entering the drainage funnel 131. Under the condition that the capacity and speed remain unchanged, the compressed gas will generate a great pressure, thereby accelerating the flow speed of the gas. The gas that quickly passes through the drainage funnel 131 will generate a faster flow speed, so that some rainwater in the rainy season will be driven by the wind source and discharged from the gap at the top of the limiting ring 12. When the water falls into the inside of the iron tile 11, part of the falling water will be pushed out in the opposite direction under the push of the upward airflow; at the same time, the inclined surface on the top surface of the drainage funnel 131 guides the remaining dripping rainwater to the sides and surroundings for discharge, and at the same time, the lateral drainage strips 113 on the two side surfaces of the drainage funnel 131 collect the dripping water, and then the raised inclined surface on the inner wall of the lateral drainage strips 113 is used to guide the rainwater to the top surface of the iron tile 11 and discharge the water.

[0031] Working principle: The heat dissipation gap between the iron tile 11 and the auxiliary iron tile 112 is used to increase the heat dissipation path for the heat of the iron tile 11 and the auxiliary iron tile 112 themselves under the sun. At the same time, the inclined surfaces on the outer surfaces of the iron tile 11 and the auxiliary iron tile 112 are used so that when the gas contacts the top surface of the iron tile 11 and the auxiliary iron tile 112, the inclined surfaces of the iron tile 11 and the auxiliary iron tile 112 are used to change the flow path and flow direction of the external gas. The gas that changes the path will mix with the gas at other positions. When the distance and gas flow remain unchanged, changing the flow path of the gas will speed up the flow speed of the gas, so that the external low-temperature gas will quickly pass through the heat dissipation gap between the iron tile 11 and the auxiliary iron tile 112 along the inclined surface of the iron tile 11, and be quickly discharged from the heat dissipation gap on the other side of the iron tile 11 and the auxiliary iron tile 112 along the path. A low air volume will be formed around the fast-flowing gas. Pressure, thereby causing the surrounding normal gas to flow rapidly in the direction of low pressure, and the rapidly flowing low pressure will carry the high-temperature hot air to flow rapidly to the outside, thereby causing the high-temperature gas accumulated at the top edge of the iron tile 11 to be quickly discharged; when the flowing gas passes through the heat dissipation gap and the top surface of the auxiliary iron tile 112, the rapidly flowing airflow will push the guide blades 123 on the outer surface of the auxiliary iron tile 112, causing the protective top 122 to rotate with the limiting ring 12 as the center, thereby driving the pushing blades 124 at the bottom end of the protective top 122 to rotate together, and the inclined surface on the surface of the pushing blades 124 generates an upward driving force during rotation, thereby accelerating the rapid flow of the heat source around the inner side surface of the top of the iron tile 11, and at the same time driving the high-temperature airflow farther away from the inner cavity of the iron tile 11 to flow rapidly, thereby quickly discharging the airflow.

[0032] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
