Energy-saving ventilation device for green building

Abstract

The invention provides an energy-saving ventilation device for a green building. The energy-saving ventilation device comprises a through pipe, a connecting sleeve and an elbow pipe, and a bottom pipe is welded at the bottom of the through pipe; a side pipe is welded on one side of the through pipe, and a guide plate is welded on the top of the side pipe; a sleeve is installed on one side of the connecting sleeve by a bolt; a fan is installed on the inner side of the connecting sleeve; fan blades are installed on one side of the side pipe, and supporting rods are arranged on the tops of the fan blades; and baffles are installed on the inner sides of the bottom pipe and the side pipes. According to the energy-saving ventilation device for the green building, air can be conveyed upwards through rotation of the fan blades, airflow at the bottom is prevented from flowing back into the building on the top; therefore, the air volumes extracted from different floors are consistent, and it is guaranteed that uniform ventilation and exhaust operation are conducted on different floors in the building; when the sleeve is vibrated, the relative position between a heavy block and the sleeve can be kept almost unchanged, and therefore the working safety of a tin foil, a touch switch and power equipment is guaranteed; and the energy-saving ventilation device is suitable for energy-saving ventilation of the green building.

[0002] In order to ensure the air environment in the building, it is necessary to install building energy-saving ventilation equipment in buildings where people gather. The patent application number is CN202010419205.9, which discloses a building energy-saving ventilation device. The existing building energy-saving ventilation equipment is basically It has the advantages of large ventilation volume, fast ventilation speed, low energy consumption, convenient installation, firm structure, and long service life, and can meet the requirements for ventilation of buildings. However, for existing building energy-saving ventilation equipment, On the one hand, in order to save the consumption of electric energy, the air duct is used to discharge the air in the building by using the principle of the chimney’s wind pulling force. Since the wind pulling force of the chimney is positively correlated with the height, it is easy to cause the exhaust speed of high-rise buildings to be slow. And because the exhaust speed at the bottom is too fast, it is easy to cause the indoor air at the bottom to flow back into the top building, which is not conducive to ensuring the exhaust operation of the top building. On the other hand, when the atmospheric pressure is low on cloudy days, the natural exhaust When the air is not smooth, the suction of the exhaust fan needs to be used for ventilation. The suction of the exhaust pipe from top to bottom will gradually become smaller as the air in the building is pumped out, which will easily cause insufficient exhaust of the bottom building, which is not conducive to Ensure uniform ventilation and exhaust operations on different floors in the building. On the other hand, when the existing pressure control mechanism uses the pressure sensing mechanism to trigger the switch to control the exhaust fan, when it is vibrated, the switch trigger mechanism is easily affected by vibration. Influence, causing the switch to be turned on and off repeatedly, which is not conducive to ensuring the safety of the switch trigger mechanism and power equipment
