Description

Technical Field

[0001] The utility model belongs to the technical field of green buildings, and in particular relates to a ventilation energy-saving device for green buildings. Background Art

[0002] Green building refers to a building that maximizes resource conservation throughout its entire life cycle, including energy conservation, land conservation, water conservation, and material conservation, protects the environment and reduces pollution, provides people with healthy, comfortable, and efficient use space, and coexists harmoniously with nature.

[0003] In order to increase the mobility of indoor air, ventilation devices are usually installed on the corresponding buildings. The ventilation devices are used to accelerate the flow of indoor and outdoor air, keep the indoor air fresh, and provide high-quality air for indoor occupants. Existing ventilation devices mostly use simple exhaust fans and other structures. The exhaust fans are used to directly connect the indoor and outdoor spaces and perform simple gas conversion. When the exhaust fans and other structures are in operation, they only rely on the rotation of the fan blades to drive the air flow, which consumes a lot of energy and is accompanied by noise. In addition to poor energy saving, they also generate noise pollution, which seriously does not conform to the application concept of green buildings.

[0004] Therefore, in view of the above-mentioned problems, this technical solution proposes a ventilation energy-saving device for green buildings. Utility Model Content

[0005] The purpose of the embodiment of the utility model is to provide a ventilation energy-saving device for green buildings, which aims to solve the problem.

[0006] The utility model is realized in this way. A ventilation energy-saving device for a green building comprises: an exhaust fan casing, an air intake casing, an indoor air intake pipe, an outdoor exhaust pipe, an indoor air intake pipe, and an outdoor exhaust pipe; the exhaust fan casing and the air intake casing are installed on the wall of the green building and are arranged in a waist-shaped structure, the indoor air intake pipe and the outdoor exhaust pipe, and the indoor air intake pipe and the outdoor exhaust pipe are connected and arranged on the indoor and outdoor side walls of the exhaust fan casing and the air intake casing respectively, the indoor air is output to the outside along the indoor air intake pipe, the exhaust fan casing, and the outdoor exhaust pipe, and the outdoor air is output to the outside along the outdoor exhaust pipe , the air intake casing, and the indoor air intake pipe are transported inward to realize the automatic conversion of the indoor air of the green building. The exhaust fan casing and the air intake casing are internally provided with wind drive components with the same direction of rotation. The wind drive components rotate outward together and are connected to a group of power mechanisms. The power mechanisms are driven by a group of power sources. When the wind drive components are running, they rotate at a lower decibel to realize the energy-saving and noise-reducing transmission conversion of indoor and outdoor air. Taking the wind drive components inside the exhaust fan casing as an example, the wind drive components include rotating shafts arranged on the upper and lower sides of the exhaust fan casing. The two rotating shafts are respectively Shoe-shaped fan blades I and II of the same size are fixedly installed. The initial distribution angle of shoe-shaped fan blades I and shoe-shaped fan blades II is ninety degrees. The indoor air intake pipe and the outdoor exhaust pipe are respectively connected to the middle position on both sides of the exhaust fan casing. The outer ends of the rotating shafts are respectively connected to the power mechanism. The power mechanism drives the shoe-shaped fan blades I and shoe-shaped fan blades II on the two rotating shafts to rotate in opposite directions. Then, by utilizing the structure and distribution position of shoe-shaped fan blades II and shoe-shaped fan blades I, when the shoe-shaped fan blades I and shoe-shaped fan blades II are separated toward one end of the indoor air intake pipe, a low pressure is formed. At this time, suction is generated at the indoor air intake pipe to draw in the gas. When the ends of the shoe-shaped fan blades I and II are closed toward the outdoor exhaust pipe, high pressure is formed to discharge the gas inside the exhaust fan casing. That is, the high and low pressure environments at the indoor air intake pipe and the outdoor exhaust pipe are utilized to realize automatic control of the flow of indoor and outdoor gas. In this process, only the simple swing of the shoe-shaped fan blades I and II is required, rather than the rotation speed of the fan blades to drive the air flow. That is, there is no need to consume too much energy and the noise generated is low, thereby realizing the energy-saving and environmental protection functions of the device.

[0007] Similarly, the operating principle of the wind drive component in the air intake casing is the same as that in the exhaust casing. It is just that the distribution position of the indoor air intake pipe and the outdoor exhaust pipe is converted to transmit the outdoor air to the indoor room.

[0008] The green building ventilation energy-saving device provided by the utility model can greatly improve the utilization rate of the servo motor power by setting a group of servo motors to simultaneously drive multiple shoe-shaped fan blades I and shoe-shaped fan blades II to rotate. At the same time, the pressure difference generated when the shoe-shaped fan blades I and shoe-shaped fan blades II rotate inside the exhaust fan casing and the air inlet casing is used to discharge air. Compared with the traditional fan-blade drive, it can greatly reduce energy consumption and reduce noise generation, thereby realizing the energy-saving and environmentally friendly ventilation function of the device.

DETAILED DESCRIPTION

[0014] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0015] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0016] like Figure 1-4As shown, a structural diagram of a ventilation and energy-saving device for a green building provided by an embodiment of the present invention includes: an exhaust fan casing 10, an air intake casing 11, an indoor air intake pipe 12, an outdoor exhaust pipe 13, an indoor air intake pipe 14, and an outdoor exhaust pipe 15; the exhaust fan casing 10 and the air intake casing 11 are installed on the wall of the green building and are arranged in a waist-shaped structure, the indoor air intake pipe 12 and the outdoor exhaust pipe 13, and the indoor air intake pipe 14 and the outdoor exhaust pipe 15 are connected and arranged on the indoor and outdoor side walls of the exhaust fan casing 10 and the air intake casing 11 respectively, and the indoor air is output to the outside along the indoor air intake pipe 12, the exhaust fan casing 10, and the outdoor exhaust pipe 13. The outdoor gas is transported inward along the outdoor exhaust pipe 15, the air inlet housing 11, and the indoor air inlet pipe 14, thereby realizing the automatic conversion of the indoor air of the green building. The exhaust housing 10 and the air inlet housing 11 are internally provided with wind drive components with the same direction of rotation. The wind drive components are connected to a group of power mechanisms 17 that rotate outward together. The power mechanism 17 is driven by a group of power sources. When the wind drive components are running, they rotate at a lower decibel to realize the energy-saving and noise-reducing transmission conversion of indoor and outdoor air. Taking the wind drive components inside the exhaust housing 10 as an example, the wind drive components include a rotating shaft 19 that is rotatably arranged on the upper and lower sides of the exhaust housing 10. The two rotating shafts 1 9 are respectively fixedly installed with shoe-shaped fan blades I 20 and shoe-shaped fan blades II 21 of the same size. The initial distribution angle of shoe-shaped fan blades I 20 and shoe-shaped fan blades II 21 is ninety degrees. The indoor air intake pipe 12 and the outdoor exhaust pipe 13 are respectively connected to the middle position on both sides of the exhaust fan housing 10. The outer ends of the rotating shaft 19 are respectively connected to the power mechanism 17. The power mechanism 17 drives the shoe-shaped fan blades I 20 and shoe-shaped fan blades II 21 on the two rotating shafts 19 to rotate in opposite directions. Then, by utilizing the structure and distribution position of the shoe-shaped fan blades II 21 and the shoe-shaped fan blades I 20, the shoe-shaped fan blades I 20 and shoe-shaped fan blades II 21 are directed toward one side of the indoor air intake pipe 12. When the side ends are separated, low pressure is formed. At this time, suction is generated at the indoor air intake pipe 12 to suck in the gas. When the shoe-shaped fan blade I 20 and the shoe-shaped fan blade II 21 are closed toward one end of the outdoor exhaust pipe 13, high pressure is formed to discharge the gas inside the exhaust fan casing 10. That is, the high and low pressure environment at the indoor air intake pipe 12 and the outdoor exhaust pipe 13 is utilized to realize the automatic control flow of indoor and outdoor gas. In this process, only the simple swing of the shoe-shaped fan blade I 20 and the shoe-shaped fan blade II 21 is required, rather than utilizing the rotation speed of the fan blades to drive the air flow, that is, no excessive energy is consumed, and the noise generated is low, thereby realizing the energy-saving and environmental protection function of the device;

[0017] Similarly, the operating principle of the wind drive assembly in the air intake casing 11 is the same as that in the exhaust casing 10, except that the distribution positions of the indoor air intake pipe 14 and the outdoor exhaust pipe 15 are converted to transmit outdoor air to the indoor room.

[0018] In the embodiment of the present utility model, a horizontal partition 16 is installed between the exhaust casing 10 and the air inlet casing 11. The partition 16 can prevent the mixing of the indoor air inlet pipe 12, the outdoor exhaust pipe 13, the indoor air inlet pipe 14, and the outdoor exhaust pipe 15 from entering and exiting the air, thereby affecting the quality of the intake air and the waste of the exhaust air; the indoor air inlet pipe 12, the outdoor exhaust pipe 13, the indoor air inlet pipe 14, and the outdoor exhaust pipe 15 are all equipped with a The clamping ring 30 is provided with a clamping groove at the air inlet and outlet of the exhaust casing 10 and the air inlet casing 11 corresponding to the clamping ring 30. The clamping ring 30 is engaged with the clamping groove to realize the detachable connection between the indoor air inlet pipe 12, the outdoor exhaust pipe 13, the indoor air inlet pipe 14, the outdoor exhaust pipe 15 and the exhaust casing 10 and the air inlet casing 11, so that the indoor air inlet pipe 12, the outdoor exhaust pipe 13, the indoor air inlet pipe 14, the outdoor exhaust pipe 15 can be replaced and the internal cleaning can be performed;

[0019] In order to improve the quality of the air input into the room and reduce the pollution-free nature of the gas discharged to the outdoors, a gas filtration and purification component is provided inside the outdoor exhaust pipe 13 and the outdoor exhaust pipe 15. The gas filtration and purification component includes a plurality of external filters 26 installed and distributed at intervals inside the outdoor exhaust pipe 13 and the outdoor exhaust pipe 15. The filter diameter of the external filter 26 decreases successively according to the direction of gas flow, and the gas is subjected to multi-stage filtration treatment. A plurality of activated carbon nets 28 are installed at equal intervals inside the outdoor exhaust pipe 13 and the outdoor exhaust pipe 15 located on the inner side of the external filter 26. The activated carbon nets 28 are used to remove odor and microscopic impurities from the gas.

[0020] In one example of the present invention, the power mechanism 17 includes a group of servo motors 22, and the output end of the servo motor 22 is connected to a driving tooth 23 through an output shaft 27. The upper and lower sides of the driving tooth 23 are engaged with driven teeth I 24, and the side of the driven tooth I 24 away from the driving tooth 23 is bonded with a driven tooth II 25. The side of the driven teeth I 24 and the driven teeth II 25 facing the inside of the exhaust fan casing 10 or the air inlet casing 11 is fixedly connected to the corresponding rotating shaft 19 through the connecting shaft 18, that is, the servo motor 22 is started to drive the driving tooth 23 to rotate, and then under the engagement between the driving tooth 23, the driven teeth I 24 and the driven teeth II 25, the shoe-shaped fan blades I 20 and the shoe-shaped fan blades II 21 at the end of the rotating shaft 19 are driven to rotate in opposite directions, thereby realizing the transmission of gas inside the exhaust fan casing 10 and the air inlet casing 11.

[0021] The above embodiment of the utility model provides a ventilation energy-saving device for green buildings. When in use, the exhaust fan housing 10 and the air inlet housing 11 are respectively installed on the wall of the green building, and then the indoor air inlet pipe 12, the outdoor exhaust pipe 13, the indoor air inlet pipe 14, and the outdoor exhaust pipe 15 are respectively connected to the indoor and outdoor. At the same time, an installation space is opened in the wall corresponding to the power mechanism 17, and the power mechanism 17 is stably installed. When running, the servo motor 22 is directly started to drive the active gear 23 to rotate, and then synchronously drives the driven gear I 24 and the driven gear I 25 to rotate. Gear II 25 rotates, thereby driving the shoe-shaped fan blades I 20 and shoe-shaped fan blades II 21 inside the exhaust fan housing 10 and the air inlet housing 11 to swing, and utilizing the distribution and contact swing between the shoe-shaped fan blades I 20 and the shoe-shaped fan blades II 21 to form suction at the indoor air intake pipe 12 and the outdoor exhaust pipe 15, and discharge blowing force at the outdoor exhaust pipe 13 and the indoor air intake pipe 14, thereby automatically converting the indoor and outdoor air flows, and then cooperating with the gas filtration and purification components in the outdoor exhaust pipe 13 and the outdoor exhaust pipe 15 to maintain the quality of the air conversion.
