Description

A green building ventilation device

Technical Field

The utility model relates to the technical field of building ventilation, in particular to a green building ventilation device.

Background technique

Building ventilation is divided into natural ventilation and mechanical ventilation, which means that the dirty air in the building is discharged directly or purified to the outside, and fresh air is added to keep the indoor air environment in line with the hygienic standards. Its purpose is: ① to ensure the removal of indoor pollutants ② to ensure the thermal comfort of indoor occupants ③ to meet the needs of indoor occupants for fresh air.

A roof ventilator is a device used for ventilation of the roofs of buildings such as workshops, factories, and warehouses. It can exhaust the hot air and dirty air inside the building through natural wind or mechanical force, thereby achieving indoor air circulation and ventilation. At present, there are two types of roof ventilation: natural ventilation and mechanical ventilation. Natural ventilation relies on the wind on the roof to drive the fan blades to rotate. Although this ventilation method does not require electricity, it is greatly affected by the weather and the ventilation effect is difficult to guarantee. Mechanical ventilation relies on motors to drive exhaust fans for exhaust. However, existing mechanical ventilation relies heavily on traditional electricity, has high operating costs, is not energy-saving and environmentally friendly, and long-term use of external dust can easily enter the room through the ventilation device and pollute the indoor air environment.

Detailed ways

The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Please refer to Figures 1-2. In the embodiment of the utility model, a green building ventilation device includes a roof plate 1 and a ventilation shaft 2. The roof plate 1 is provided with the ventilation shaft 2. The ventilation shaft 2 is installed with a dustproof net tube 11. The dustproof net tube 11 is installed with a roof plate 4. The roof plate 4 is installed with a cover body 6. The top of the cover body 6 is installed with a solar power generation component 8. The top of the roof plate 4 and the top of the cover body 6 are both provided with heat dissipation holes 16. The heat dissipation holes 16 can quickly dissipate the heat accumulated in the cover body 6. The cover body 6 is installed with screws 7. The cover body 6 is connected to the roof by the screws 7. The board 4 is fixedly connected, the first motor 9 is installed on the top plate 4, the output shaft of the first motor 9 is fixedly connected to the exhaust fan blades 10 arranged in the dustproof mesh tube 11, and a battery 15 is installed on the top plate 4. The solar power generation component 8 is electrically connected to the battery 15, and the battery 15 is electrically connected to the first motor 9. It should be noted that the battery 15 is also connected to the traditional indoor socket through a wire. The socket is not powered at ordinary times. When solar power generation is insufficient, the staff can press the socket power switch to supply traditional AC power to the battery to meet the power needs in an emergency.

Please refer to Figures 1-3. Guide rods 3 are provided in front, behind and on one side of the dustproof mesh tube 11. The two ends of the guide rod 3 are fixedly connected to the ventilation shaft 2 and the top plate 4 respectively. A screw rod 5 is provided on the other side of the dustproof mesh tube 11. The bottom end of the screw rod 5 is rotatably connected to the bearing installed on the ventilation shaft 2, and the top end of the screw rod 5 is directly connected to the output shaft of the second motor 14 installed on the top plate 4. A screw nut 13 is installed on the screw rod 5. A cleaning ring 12 is installed on the screw nut 13 and the three guide rods 3. The cleaning ring 12 includes a ring body 1201 and bristles 1202.

The battery 15 is also connected to the timing switch 17 installed on the top plate 4, and the timing switch 17 is electrically connected to the second motor 14.

It should be noted that the solar power generation component 8 is an existing mature component, which mainly includes a solar panel, a bracket, an inverter and a solar controller. When working, under the control of the solar controller, the solar panel power converts DC power into AC power through the inverter and transmits it to the battery.

The working principle of the utility model is:

When in use, the electric energy generated by the solar power generation component 8 is automatically input into the battery 15 for storage, and then the first motor 9 is powered by the battery 15. The first motor 9 drives the exhaust fan blades 10 to rotate to draw the indoor air upward, thereby accelerating the indoor and outdoor air circulation. At the same time, the dustproof mesh tube 11 can prevent external dust from entering the ventilation shaft 2 and polluting the indoor air. The circuit between the battery 15 and the second motor 14 is controlled by the timing switch 17. When the second motor 14 is energized, it drives the screw rod 5 to rotate, and the screw rod 5 drives the cleaning ring 12 to move from top to bottom or from bottom to top along the guide rod 3. The dust on the surface of the dustproof mesh tube 11 is cleaned by the bristles 1202 on the cleaning ring 12 to prevent the dustproof mesh tube 11 from being blocked by dust.
