These blades have excellent flexibility and can be adjusted at multiple angles according to actual needs, so as to achieve precise control of air flow direction and flow. Therefore, the louver vent has a very wide range of applications. Whether it is commercial buildings, office spaces, or home environments, it can be seen almost anywhere a comfortable air environment is needed. In addition, the existing louver vents are usually designed to be circular in order to meet the aesthetic taste of modern people. For example, an ABS circular louver outlet disclosed in the publication number CN207585043U is a circular design.

[0026] The adjustment mechanism 3 can automatically open, close and adjust the direction of the blades according to the wind direction and rainfall. Figure 6The adjustment mechanism 3 also includes an adjustment chamber 31 opened inside the connecting ring 5, and the inner peripheral wall of the connecting ring 5 is rotatably connected to a plurality of rotating rods 32, and the outer wall of the rotating rod 32 is fixedly connected to a blade 33, one end of each of the plurality of rotating rods 32 passes through the inner wall of the connecting ring 5 and extends into the adjustment chamber 31, and the ends of the rotating rods 32 in the adjustment chamber 31 are fixedly connected to a second gear 35, and the inner wall of the adjustment chamber 31 is provided with a plurality of sliding grooves 36 corresponding to the position of the second gear 35, and the inner wall of the sliding groove 36 is slidably connected to a support frame 37, and the top of the support frame 37 is fixedly connected to a first tooth plate 38 respectively meshing with each second gear 35, and a connecting block 39 is fixedly connected between every two adjacent first tooth plates 38.

[0027] Among them, the inner wall of the adjustment chamber 31 is fixedly connected to the second motor 310, the output end of the second motor 310 is fixedly connected to the rotating rod 311, the outer wall of the rotating rod 311 is fixedly connected to the third gear 312, and the side wall of the first tooth plate 38 on the symmetry line of the connecting ring 5 is fixedly connected to the second tooth plate 34 meshing with the third gear 312.

[0028] The working principle of the present invention is as follows: In this case, the air inlet angle of the blade 33 can be automatically adjusted according to the wind direction. The specific detection and adjustment methods are as follows: When the wind blows from the upper left (upper left of the front side, upper left of the rear side), upper right (upper right of the front side, upper right of the rear side) or lower left (lower left of the front side, lower left of the rear side), lower right (lower right of the front side, lower right of the rear side)), the first wind measuring plate 111 will be moved. Different directions will correspond to different movement modes of the first wind measuring plate 111 (the above wind directions are as follows: Figure 1 direction as an example), as follows: When the wind blows from the upper left: the first wind measuring plate 111 will be blown by the wind, causing the left side of the first wind measuring plate 111 to lift upward, thereby driving the first conductive rod 113 to slide inside the first hemispherical resistor plate 115 toward the right side of the first hemispherical resistor plate 115, and then the current monitoring module in the PLC controller detects the current change through the first sliding rheostat. Since the hemispherical resistor plate is composed of a resistance wire surrounded by a thread, different currents will appear when the first conductive rod 113 contacts different positions inside the first hemispherical resistor plate 115. Therefore, different positions of the first conductive rod 113 are fed back through currents of different intensities, thereby feeding back the wind direction and wind strength. When the wind blows from the upper right, the movement trajectory of the first conductive rod 113 is opposite to the movement trajectory of the first conductive rod 113 when the wind blows from the upper left; When the wind blows from the upper left of the front side: the first wind measuring plate 111 is blown by the wind, which will cause the right rear side of the first wind measuring plate 111 to drop, and then drive the first conductive rod 113 to move in the first hemispherical resistor plate 115 to the upper left of the front side of the first hemispherical resistor plate 115, and the current monitoring module is also used to detect and feedback the wind direction and wind strength; When the wind blows from the upper left rear side, the movement trajectory of the first conductive rod 113 is opposite to that when the wind blows from the upper left front side; When the wind blows from the lower left, the movement trajectory of the first conductive rod 113 is consistent with the movement trajectory when the wind blows from the upper right; when the wind blows from the lower right, the movement trajectory of the first conductive rod 113 is consistent with the movement trajectory when the wind blows from the upper left; when the wind blows from the lower left of the front side, the movement trajectory of the first conductive rod 113 is consistent with the movement trajectory when the wind blows from the upper left of the rear side; when the wind blows from the lower left of the rear side, the movement trajectory of the first conductive rod 113 is consistent with the movement trajectory when the wind blows from the upper right of the front side.

[0029] Since the currents in different directions are consistent, additional auxiliary detection is required. Therefore, the piezoelectric pressure sensor on the first wind measuring plate 111 senses the pressure generated by the wind to distinguish between the upper wind and the lower wind.

[0030] The second wind measuring plate 112 can also measure different wind sources, but the difference between the first wind measuring plate 111 and the second wind measuring plate 112 is that the first wind measuring plate 111 cannot measure the wind coming from the left and right sides, and the second wind measuring plate 112 cannot measure the wind coming from the top and bottom. When the wind comes from the top and bottom, the first wind measuring plate 111 will drive the first conductive rod 113 to slide in the first hemispherical resistor plate 115 toward the front side of the first hemispherical resistor plate 115, and the first wind measuring plate 111 will drive the first conductive rod 113 to slide in the first hemispherical resistor plate 115 toward the rear side of the first hemispherical resistor plate 115. When the wind comes from the left and right sides, the second wind measuring plate 112 will drive the second conductive rod 114 to slide in the second hemispherical resistor plate 116 toward the front side of the second hemispherical resistor plate 116, and the second wind measuring plate 112 will drive the second conductive rod 114 to slide in the second hemispherical resistor plate 116 toward the rear side of the second hemispherical resistor plate 116.

[0031] Then the wind speed is detected by the wind speed detection component 12, and the specific detection process is as follows: The wind force drives the two wind wheels 125 in different directions to rotate, thereby driving the first detection rod 123 and the second detection rod 124 to rotate, and further driving the conductive rod 126 to rotate, and then cutting the magnetic field between the two permanent magnet plates 127 (the principle of cutting magnetic flux lines), and then transmitting the generated current to the capacitor through the conductive rod 126 for storage for indoor use. At the same time, the current monitoring module in the PLC controller detects the size of the generated current, and then the wind speed is fed back in real time.

[0032] When the wind speed is relatively low, the second motor 310 is started by controlling the PLC controller, and the second motor 310 drives the rotating rod 311 to rotate, thereby driving the third gear 312 to rotate, and the second tooth plate 34 is driven to move by the third gear 312, thereby driving the first tooth plate 38 to move synchronously, and then all the first tooth plates 38 are driven to move synchronously through the connecting block 39, thereby driving all the second gears 35 to rotate, thereby driving the rotating rod 32 to rotate, and further rotating and adjusting the blades 33, so that the blades 33 are turned upward, thereby allowing air to enter and exit normally. When the detected wind speed is too high or the wind strength is too high, the blades 33 cannot be opened to prevent the excessive wind speed from damaging the items in the building.

[0033] Then the PLC controller starts the first motor 9 according to the detected wind direction, and drives the first gear 8 to rotate through the first motor 9, thereby causing the annular rack 6 to drive the connecting ring 5 to rotate, thereby achieving the purpose of adjusting the air inlet between the blades 33 and the blades 33. For example, when the wind direction is blowing from the upper left front side, all the lower sides should be facing the upper left front side to facilitate air entry.

[0034] When it rains, rainwater is caught by the receiving frame 21 and then filtered by the filter plate 23. When the rainfall is small, the rainwater will be discharged through the drain pipe 29. When the rainfall is heavy, the rainwater will not have time to be discharged from the drain pipe 29, so it will be slowly stored in the receiving frame 21. Then, when the water level monitoring rod 22 detects that the rainwater is slowly accumulating, the PLC controller will control the blade 33 to close to prevent rainwater from entering the building. At the same time, the PLC controller will energize the regulating solenoid valve to make the regulating solenoid valve open wider to discharge the rainwater. By starting the electric hydraulic rod 26, the push plate 27, the cleaning plate 210, the connecting plate 28, and the sliding plate 25 are pushed forward to push out the impurities filtered on the filter plate 23.

[0035] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
