[0002] Aluminum alloy doors and windows are widely used in modern buildings. Their wind pressure resistance is an important indicator to ensure the safe use of doors and windows under severe weather conditions. In order to accurately evaluate the wind pressure resistance of aluminum alloy doors and windows, special measuring devices are required for testing.

[0003] A device for measuring the wind pressure resistance of aluminum alloy doors and windows in ultra-low energy consumption buildings disclosed in a patent application with reference publication number CN118482890A utilizes the internal wind pressure of a bellows to be released through a through hole. Since the through hole is located at a certain position of the aluminum alloy door and window, the wind pressure can be applied to a certain position of the aluminum alloy door and window for wind pressure measurement. In this way, the wind pressure resistance of the entire surface of the aluminum alloy door and window is measured in cooperation with the first air outlet pipe. This simultaneous point and surface measurement method can make the wind pressure resistance measurement of the aluminum alloy doors and windows more accurate. In addition, the time for measuring the wind pressure of the aluminum alloy doors and windows can be set according to the time when the sealing ball moves inside the second air outlet pipe and the second air outlet pipe is closed, thereby improving the diversity of wind pressure measurement.

According to the test requirements, the front blowing component 61 and the side blowing component 62 can be quickly and flexibly switched to test the aluminum alloy door and window. 9 can measure the wind pressure resistance in the required direction, and by adjusting the overlapping angle between the arc-shaped opening 637 and the arc-shaped groove 634, the wind pressure resistance of the aluminum alloy door and window 9 under the required wind pressure can be measured. It is convenient to use. Through the mutual cooperation between the communication box 121, the fan 122 and the temperature control mechanism 123, wherein the temperature control mechanism 123 is mainly composed of a heater and a refrigerator, the gas sucked by the fan 122 can be heated or cooled in advance, so that cold air, hot air or normal temperature air with a preset temperature is input into each wind pressure resistance measuring mechanism 6, so that the performance of the aluminum alloy door and window 9 under different temperature and wind pressure conditions can be evaluated.

[0028] The embodiment of the present invention further provides a method for measuring the wind pressure resistance of aluminum alloy doors and windows, using a device for measuring the wind pressure resistance of aluminum alloy doors and windows. The specific method includes the following steps: Step 1, open the sealing door 13, place multiple aluminum alloy doors and windows 9 in each measuring cavity through each placement groove 32, the front of the aluminum alloy door and window 9 contacts the rear of the corresponding two baffles 8, and then drive the limit mechanism 7 to limit the aluminum alloy door and window 9. In the process of driving the limit mechanism 7, start the servo motor 75 to drive the screw rod 74 to rotate, so that the H-shaped frame 73 moves forward, and the four T-shaped top rods 72 move forward accordingly, and cooperate with the corresponding two baffles 8 front and back to clamp and limit the aluminum alloy door and window 9; Step 2, then adjust each wind pressure resistance measuring mechanism 6 according to the measurement requirements, and adjust the wind blowing to the aluminum alloy door and window 9 to a preset force and a preset direction. During the adjustment of the wind pressure resistance measuring mechanism 6, when it is necessary to simulate the situation where the aluminum alloy door and window 9 encounters positive wind pressure in the actual environment, switch the positive blowing component 61 to the working state. During the process, the hand wheel 653 is used to drive the worm 652 to rotate, and the worm gear 638 and the adjustment disk 635 rotate accordingly. At the same time, observe the scale groove 655 pointed to by the indicator needle 654, so as to accurately adjust the rotation angle of the worm gear 638, that is, accurately adjust the arc When the arc-shaped opening 637 is completely overlapped with the lowest arc-shaped groove 634, the positive blowing assembly 61 is switched to the working state, and the wind generated by the wind conveying mechanism 12 will blow toward the aluminum alloy door and window 9 through the positive blowing assembly 61, and the wind pressure is minimum at this time. When it is necessary to simulate the wind pressure conditions of the aluminum alloy door and window 9 at different lateral angles in the actual environment, the corresponding side blowing assembly 62 is switched to the working state. During the process, the hand wheel 653 is used to drive the worm 652 to rotate, and the scale groove 655 pointing to the indicator needle 654 is observed. When the arc-shaped opening 637 is aligned with the scale groove 655 located in the middle of the two sides, the wind pressure is minimized. When one of the required arc grooves 634 is completely overlapped, the corresponding side blowing assembly 62 is switched to the working state, and then the latch 626 is pulled upward to release the lock between the hollow plate 2 621 and the horizontal plate 31, and the connecting shaft 2 623 is rotated. During the process, the scale groove 1 34 pointed by the pointer is observed, and the angle of the hollow plate 2 621 can be accurately adjusted, and the wind direction blown out through the blowing hole 2 622 can be accurately changed, that is, the wind direction blowing toward the aluminum alloy door and window 9 is changed, so that the wind pressure situation of the aluminum alloy door and window 9 at different lateral angles in the actual environment can be simulated, and the wind generated by the wind conveying mechanism 12 will pass through The corresponding side blowing assembly 62 blows sideways toward the aluminum alloy door and window 9, and the wind pressure is minimum at this time, and by adjusting the overlap angle between the arc-shaped opening 637 and the arc-shaped groove 634, the wind pressure resistance of the aluminum alloy door and window 9 under the required wind pressure can be measured, wherein since the power of the fan 122 remains unchanged, when the arc-shaped opening 637 and the arc-shaped groove 634 completely overlap, the wind pressure blown out through the blowing hole is minimum, and when the overlap angle between the arc-shaped opening 637 and the arc-shaped groove 634 gradually decreases, the airflow is forced to pass through a smaller space, thereby generating a higher pressure at the blowing hole, and the wind pressure blown out through the blowing hole gradually increases; Step 3, then start the wind conveying mechanism 12, use the fan 122 to draw in the external air through the air inlet pipe 124, and first pass through the temperature control mechanism 123, wherein the temperature control mechanism 123 is mainly composed of a heater, a refrigerator and a controller, the heater, the refrigerator and the controller are all prior arts known to those skilled in the art, the heater and the refrigerator can preheat or cool the gas sucked by the fan 122, and the controller controls when hot air is needed, the heater works, when cold air is needed, the refrigerator works, and when normal temperature air is needed, the heater and the refrigerator do not work, so that the input with preset temperature is input into each wind pressure resistance measuring mechanism 6 The cold wind, hot wind or normal temperature wind can evaluate the performance of the aluminum alloy doors and windows 9 under different temperature and wind pressure conditions. The wind adjusted to the preset temperature first enters the Huitong box 121, and then enters the corresponding vent 636 through each L-shaped tube 64, and then passes through the arc-shaped mouth 637, the arc-shaped groove 634 and the arc-shaped cover 632, and then enters the corresponding hose, and is blown out through the corresponding blowing holes, so that the wind blows to each aluminum alloy door and window 9 according to the preset force and preset direction. In the process, the wind force is measured by the wind pressure sensor 11, and the deformation of the aluminum alloy door and window 9 is measured by the displacement sensor 10 arranged at the rear of the aluminum alloy door and window 9, so that the wind pressure resistance of the aluminum alloy door and window 9 can be measured.
