[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] This utility model provides a technical solution for an energy-saving ventilator for building construction.

[0031] like Figure 1 - Figure 6As shown, the device includes a ventilation duct 1, with a rotating ventilation ball 2 rotatably connected to the top of the ventilation duct 1. The rotating ventilation ball 2 includes a rotating base 21, a top plate 22, and an air inlet plate 23. The rotating ventilation ball 2 can rotate by utilizing the flow of natural wind in the environment. When natural wind blows over the rotating ventilation ball 2, it can drive the rotating ventilation ball 2 to rotate on the top surface of the ventilation duct 1 through the air inlet plate 23. At this time, a positive pressure is formed on the windward side of the rotating ventilation ball 2, and a negative pressure zone is formed on the leeward side. The wind pressure difference between the two, combined with the internal structural design of the device, allows fresh air to enter the ventilation duct 1 through the rotating ventilation ball 2, which helps to improve the indoor air quality.

[0032] The rotating base 21 is rotatably installed at the top of the ventilation duct 1, and the top plate 22 is set above the rotating base 21. A set of air inlet plates 23 is set between the rotating base 21 and the top plate 22. The two ends of the air inlet plates 23 are fixedly connected to the rotating base 21 and the top plate 22 respectively. The air inlet plates 23 are designed as streamlined arcs. By utilizing the height and curvature of the device body to form a large volume, the device can effectively improve its ability to collect and discharge air. When the natural wind in the environment is small, this design allows the ventilator to better collect indoor air and then discharge it outdoors, which facilitates ventilation operations inside and outside the building.

[0033] The ventilation duct 1 is equipped with a rotating rod 3. The top end of the rotating rod 3 is fixedly connected to the top plate 22, and the bottom end of the rotating rod 3 passes through the dustproof plate 5 and is rotatably connected to the dustproof plate 5. The top plate 22 and the dustproof plate 5 provide a limiting and fixing effect for the rotation of the rotating rod 3. When the rotating ventilation ball 2 rotates, it can drive the rotating rod 3 to rotate. The rotation of the rotating rod 3 can drive the guide plate 4 to rotate. At the same time, the rotation of the rotating rod 3 can also provide power for the cleaning operation of the cleaning plate 6, which simplifies the power structure of the device and improves the ventilation and energy-saving effect of the device.

[0034] A permanent magnet motor 11 is fixedly installed on the bottom surface of the dustproof plate 5. The bottom end of the rotating rod 3 is fixedly connected to the output shaft of the permanent magnet motor 11. When the wind speed in the external environment is low, the rotating ventilation ball 2 will not rotate. If the ventilation operation of the device needs to be started at this time, the permanent magnet motor 11 can be controlled. The permanent magnet motor 11 can drive the rotating rod 3 to rotate when it is started, thereby realizing the two control modes of automatic ventilation and electric ventilation of the device, improving the applicability of the device. The permanent magnet motor 11 is existing technology and will not be described in detail in this application. The output shaft of the permanent magnet motor 11 can drive the rotating rod 3 to rotate when it is powered on, and can rotate freely when it is not powered on, without hindering the rotation of the rotating rod 3.

[0035] A set of guide plates 4 are fixedly connected to the outer surface of the rotating rod 3, and a flashing groove 9 is fixedly connected to the inner wall of the ventilation pipe 1. The outer surface of the ventilation pipe 1 is provided with a drain outlet 10 that matches the flashing groove 9. The end of the guide plate 4 is fixedly connected to the rotating base 21. The rotating rod 3 and the guide plate 4 can fix and support the rotating ventilation ball 2. They have a specific tilt angle and area, which can guide the air to prevent air turbulence and ensure better exhaust effect. The flashing groove 9 can collect the rainwater on the inner wall of the ventilation pipe 1 into the groove and discharge it through the drain outlet 10 to prevent rainwater from entering the building through the ventilation pipe 1 and prevent rainwater from seeping into the building and causing damage to the building.

[0036] The inner wall of the ventilation duct 1 is fixedly connected with a dustproof plate 5. The dustproof plate 5 can block dust and small particulate matter carried in the air, preventing dust and other particles from entering the building interior along with the gas and causing pollution to the indoor environment. This improves the ventilation effect of the device and strengthens the protection performance of the indoor environment.

[0037] A cleaning plate 6 is slidably connected to the top surface of the dustproof plate 5. A dust removal port 8 is provided on the outer surface of the ventilation pipe 1. The dust removal port 8 is adapted to the cleaning plate 6. The bottom surface of the cleaning plate 6 has bristles adapted to the dustproof plate 5, which can clean the dust and other impurities blocked by the dustproof plate 5. The dust and other impurities are shoveled into the interior of the cleaning plate 6 by the protruding inclined surface of the bottom surface of the dustproof plate 5. The end of the cleaning plate 6 is slidably connected to the inner wall of the ventilation pipe 1, and the two have a certain degree of airtightness. When the cleaning plate 6 slides to clean the dust, the dust will be swept away and retained inside the cleaning plate 6 under the action of centrifugal force. When the end of the cleaning plate 6 passes through the dust removal port 8, the dust and other impurities inside the cleaning plate 6 will be discharged from the ventilation pipe 1 through the dust removal port 8 under the action of centrifugal force, thereby completing the automatic cleaning operation of the dustproof plate 5 and avoiding the dust blockage of the dustproof plate 5 after long-term use, which would affect the ventilation effect of the device.

[0038] The ventilation duct 1 is equipped with a transmission mechanism 7. The transmission mechanism 7 includes a reduction sleeve 701 sleeved on the outside of the rotating rod 3. The cleaning plate 6 is fixedly connected to the reduction sleeve 701. The reduction sleeve 701 is rotatably connected to the dustproof plate 5 and the rotating rod 3. The transmission mechanism 7 mainly serves to reduce speed, which can reduce the rotation speed of the rotating rod 3 and transmit it to the cleaning plate 6, so that the cleaning plate 6 rotates to perform cleaning operations. This simplifies the power structure of the device, improves the energy-saving effect of the device, and avoids the rotating ventilation ball 2 rotating too fast in windy conditions, which would cause the cleaning plate 6 to clean too frequently and thus reduce the service life of the device.

[0039] The transmission plate 702 is hinged to the inside of the reduction sleeve 701 via a pin. The transmission sleeve 703 is fixedly connected to the outer surface of the rotating rod 3. The rotation of the rotating rod 3 can drive the transmission sleeve 703 to rotate. The rotation of the transmission sleeve 703 can push the transmission plate 702 at a certain frequency. At this time, the transmission plate 702 can drive the reduction sleeve 701 to rotate, thereby driving the cleaning plate 6 to rotate. When the transmission sleeve 703 is pushed to a certain position, the transmission plate 702 will tilt. At this time, the transmission sleeve 703 will disengage from the transmission plate 702 and reset, so that it can be pushed by the transmission sleeve 703 again. When the transmission plate 702 is pushed, it can drive the reduction sleeve 701 to rotate at a certain angle, thereby driving the cleaning plate 6 to rotate, so that the cleaning plate 6 cleans the surface of the dustproof plate 5.

[0040] A set of springs 704 are fixedly connected to the outer surface of the transmission plate 702. Each spring 704 is fixedly connected to the reduction sleeve 701. The springs 704 provide support for the tilting and resetting of the transmission plate 702. The number of teeth on the surface of the transmission sleeve 703 and the area of ​​the transmission plate 702 are proportional to the cleaning speed of the cleaning plate 6. During production, the construction personnel can adjust the dust cleaning efficiency of the cleaning plate 6 according to the actual installation environment requirements of the device by changing the number of teeth on the surface of the transmission sleeve 703 or the area of ​​the transmission plate 702, thereby improving the applicability of the device.

[0041] Working principle: Construction workers first install the device in a suitable working position. When there is natural wind in the environment, the rotating ventilation ball 2 will rotate accordingly, and fresh air will be delivered to the ventilation duct 1 through the air inlet plate 23. Then, it will be delivered to the building interior through the ventilation duct 1. During the delivery process, the dustproof plate 5 will filter the dust and other impurities carried in the air to prevent dust from polluting the indoor environment. When the rotating ventilation ball 2 rotates, the rotating rod 3 will also rotate, thereby driving the transmission sleeve 703 to rotate. The rotation of the transmission sleeve 703 can drive the transmission plate 702 at a certain frequency, thereby driving the reduction sleeve 701 to rotate at a slower speed. The rotation of the reduction sleeve 701 can drive the cleaning plate 6 to rotate, thereby cleaning the surface of the dustproof plate 5. When the end of the cleaning plate 6 passes through the dust removal port 8, the cleaned dust and other impurities can be thrown out by centrifugal force, thereby avoiding the problem of dust accumulating on the dustproof plate 5 and causing blockage. This helps to ensure that the device can perform ventilation operations normally.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
