With the rapid development of urbanization, high-rise buildings are becoming more and more common because they can provide more living and working space within a limited ground space. The wind environment analysis methods and devices for high-rise buildings mainly include computational fluid dynamics (CFD) simulation, wind tunnel experiments, field measurements, and evaluation and prediction software. These methods and devices can help architects and engineers predict the impact of wind on high-rise buildings, including wind pressure distribution, wind-induced vibrations, and other issues, to ensure the safety and comfort of the building.

In this way, air is provided to the corridors or indoors of each floor of the building. However, the wind pressure inside the air inlet of the air duct is close to the outdoor of the high-rise building, and the wind speed and pressure inside the air inlet of the air duct fluctuate greatly due to the influence of the high-altitude wind speed and pressure.

[0015] According to a high-rise building wind environment analysis device, a high-rise building wind environment analysis method is also provided, which mainly includes the following steps:

[0016] S1. Opening of the air inlet: The electric push rod is remotely controlled to push the rack to slide on the side wall surface of the air inlet frame. During the sliding process of the rack, each wind shield is pushed to flip inside the air inlet of the air inlet frame, so that each wind shield flips to a horizontal position, and the air inlet is opened and normally open.

[0017] S2, wind cup falling: when the wind speed needs to be detected, the threaded screw is driven to rotate by remotely controlling the servo motor, and the movable slider is pushed to slide vertically up and down on the surface of the side support box, and the wind cup is controlled to move downward from the storage groove on the top surface of the inner wall of the tuyere frame to a suitable height to detect the wind speed inside the tuyere frame;

[0018] S3, external wind speed and air volume detection: When the wind cup in the above step S2 moves to a suitable height, the extension arm is driven to swing to a vertical angle with the arc-shaped bending rod by controlling the servo motor 2, and the swing angle of the extension arm is locked by the electromagnetic relay on the side positioning plate 2, and the extension arm is extended outward, and the wind temperature meter at the top of the extension arm extends to the outside of the air outlet frame through the opened wind shield plate to detect the wind speed and air volume outside the air outlet frame;

[0019] S4, retracting the wind temperature meter: after the wind speed and air volume are detected in the above step S3, the extension arm is automatically shortened, and the wind temperature meter retreats to the inside of the air outlet frame by passing through the opened wind shield;

[0020] S5, extension arm return: after the extension arm is shortened in the above step S4, the electromagnetic relay on the second side positioning plate stops working, and the extension arm is driven by the second servo motor to rotate to a position parallel to the top arc-shaped bending rod;

[0021] S6, the wind cup and the extension arm rise and hide: the servo motor 1 drives the threaded screw to rotate, pushes the movable slider to rise and slide on the surface of the side support box, and controls the wind cup and the extension arm to rise to the storage groove on the top surface of the inner wall of the tuyere frame for hiding;

[0022] S7. Closing the air suction port: When the air suction port needs to be closed, the electric push rod is remotely controlled. The electric push rod pushes the rack to slide on the side wall surface of the air suction port frame. During the sliding process of the rack, each wind shield is pushed to flip inside the air suction port of the air suction port frame, so that each wind shield flips to a vertical position, and the air suction port is closed.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. The present invention installs an air vent frame at the air inlet position on the outer surface of the building side wall, uses the air vent frame as a shutter to protect the air inlet, and adopts a multi-faceted wind shield spliced ​​at the air inlet position of the air vent frame to form a cross-sectional wind window. Several wind shields in the air inlet are flipped synchronously, and there is no need for personnel to contact the air vent frame. The opening or closing of the cross-sectional wind window can be remotely controlled, thereby reducing the waste of personnel scheduling.

[0025] 2. When the wind speed needs to be detected, the threaded screw is driven to rotate by remotely controlling the servo motor, and the movable slider is pushed to slide vertically up and down on the surface of the side support box, and the wind cup is controlled to move downward from the storage slot on the top surface of the inner wall of the tuyere frame to a suitable height. When the outside air volume enters from the air inlet of the tuyere frame, the wind cup in the middle position of the inner wall of the tuyere frame is pushed to rotate. The wind cup adopts a three-cup integrated structure, which can sense even the slightest wind force. The wind speed required for starting is low, and the wind speed measurement is more accurate.

[0026] The starting wind speed is as low as <0.5m / s, and the maximum measuring range is 50m / s, which can better detect the wind speed and air volume inside the air outlet frame; the wind cup is made of aluminum alloy as a whole, with high product strength and long service life, which is very suitable for wind speed detection at high altitudes.

[0027] 3. When it is necessary to measure the wind speed inside the air outlet frame and the wind speed outside the air outlet frame at the same time, the extension arm is driven by servo motor 2 to swing to a perpendicular angle to the arc-shaped bent rod, and the electromagnetic relay on the side positioning plate 2 is started and stopped to adsorb and lock the swing angle of the extension arm, and the extension arm is extended outward, and the wind temperature meter at the top of the extension arm extends to the outside of the air outlet frame through the opened wind shield to detect the wind speed and air volume outside the air outlet frame; the position of the extension arm is adsorbed and locked by the electromagnetic relay on the side positioning plate 2, so that the wind temperature meter extended outside the air outlet frame is not easy to swing during the wind measurement process, thereby effectively protecting and stabilizing the wind temperature meter.

[0028] 4. The wind temperature meter described in the present invention is a thermal anemometer, which adopts a thin thermal probe that can be easily extended from between two adjacent horizontal windshields to the outside of the air outlet frame. The thermal anemometer is sensitive and is equipped with a four-section retractable extension arm. The four-section retractable extension arm can be extended to 400mm at the longest, and can be easily extended or retracted from between two adjacent windshields. Moreover, since the thermal probe of the thermal anemometer is thin and small in size, and the extension arm can be axially extended and retracted, the extension arm does not take up too much space when extended between two adjacent windshields, and has little effect on the air intake of the air intake.

[0029] 5. When the wind cup and the wind temperature meter are retracted, the present invention uses the four-section telescopic extension arm to retract, and can retract to a maximum length close to that of one section of the arm, and is driven by servo motor 2 to rotate to a position parallel to the arc-shaped curved rod at the top; then the servo motor 1 drives the threaded screw to rotate, pushing the movable slider to slide upward on the surface of the side support box, controlling the wind cup and the extension arm to rise to the storage groove on the top surface of the inner wall of the air outlet frame for hiding; while being able to effectively protect the wind cup, the wind temperature meter and the extension arm, it can reduce the impact on the air volume of the air intake port during daily air intake. At the same time, the extension arm is locked by the electromagnetic relay on the side positioning plate 1, thereby effectively improving the structural firmness hidden in the storage slot and preventing the air inlet from swinging due to the increased wind force caused by the narrow channel effect, thereby effectively improving the protection of the wind temperature meter. The present invention hides the wind cup and the wind temperature meter at the top of the inner wall of the air outlet frame, so that when the wind environment needs to be detected, it is convenient to realize automatic descending detection without manual approaching operation. When the wind environment does not need to be detected, it automatically rises and is stored without affecting the air intake of the air duct (3) of the building side wall (2).

[0063] The wind speed sensor cup 19 disposed at the top of the arc-shaped bent rod 21 is located in the middle of the left and right sides of the inner wall of the tuyere frame 1, so as to facilitate the wind cup 18 and the wind temperature meter 24 to perform accurate measurement.

[0064] A receiving groove 14 is provided on the top surface of the inner wall of the tuyere frame 1 , and the wind cup 18 , the wind speed sensor cup 19 and the wind temperature meter 24 are embedded in the receiving groove 14 on the top surface of the inner wall of the tuyere frame 1 .

[0065] Specifically, in the present embodiment, when it is necessary to measure the wind speed inside the air outlet frame 1, it is also necessary to measure the wind speed outside the air outlet frame 1. The servo motor 31 is used to drive the extension arm 23 to swing to a perpendicular angle to the arc-shaped bent rod, and the electromagnetic relay 34 on the side positioning plate 29 is started and stopped to adsorb and lock the swing angle of the extension arm 23. The extension arm 23 extends outward, and the wind temperature meter 24 at the top of the extension arm 23 passes through the opened wind shield 6 to extend to the outside of the air outlet frame 1 and detects the wind speed and air volume outside the air outlet frame 1. The electromagnetic relay 34 on the side positioning plate 29 adsorbs and locks the position of the extension arm 23, so that the wind temperature meter 24 extending outside the air outlet frame 1 is not easy to swing during the wind measurement process, thereby effectively protecting and stabilizing the wind temperature meter 24.

[0066] Specifically, in the present embodiment, the wind temperature meter 24 of the present invention is a thermal anemometer, which adopts a thin thermal probe that can be easily extended from between two adjacent horizontal wind shields 6 to the outside of the air outlet frame 1. The thermal anemometer is sensitive and is equipped with a four-section retractable extension arm 23. The four-section retractable extension arm 23 can be extended to 400 mm at the longest, and can be easily extended or retracted from between two adjacent wind shields 6. Moreover, since the thermal probe of the thermal anemometer is thin and small in size, and the axial extension of the extension arm 23 is cooperated, the extension arm 23 is extended between two adjacent wind shields 6 without occupying too much space, and the impact on the air intake of the air intake 12 is small.

[0067] Specifically, in this embodiment, when the wind cup 18 and the wind temperature meter 24 are retracted, the four-section telescopic extension arm 23 is used to retract them, and the maximum retraction length is close to that of one section arm 2301, and the servo motor 2 31 is used to drive the screw rod 17 to rotate to a position parallel to the arc-shaped bent rod at the top; the servo motor 13 is then used to drive the threaded screw 17 to rotate, and the movable slider is pushed to rise and slide on the surface of the side support box 15, and the wind cup 18 and the extension arm 23 are controlled to rise to the storage groove 14 on the top surface of the inner wall of the air outlet frame 1 to hide; while being able to effectively protect the wind cup 18, the wind temperature meter 24 and the extension arm 23, the suction is reduced during daily air intake. The air volume of the air vent 12 is affected. At the same time, the extension arm 23 is locked by the electromagnetic relay 34 on the side positioning plate 28, thereby effectively improving the structural firmness hidden in the storage slot 14, and preventing the air inlet from being affected by the narrow effect of the wind force increase and driving the extension arm 23 hidden in the storage slot 14 to swing, thereby effectively improving the protection of the wind temperature meter 24. The present invention hides the wind cup 18 and the wind temperature meter 24 at the top of the inner wall of the air vent frame 1, so that when the wind environment needs to be detected, it is convenient to realize automatic descent detection without manual approach operation. When the wind environment does not need to be detected, it automatically rises and is stored without affecting the air intake of the air duct 3 of the side wall 2 of the building.
