Description

Technical Field

[0001] The utility model relates to the field of bridge monitoring, in particular to a viaduct wind monitoring mechanism based on BIM technology. Background Art

[0002] With the continuous expansion of modern transportation networks, the safety and stability of viaducts, as important transportation facilities connecting cities and villages and crossing natural obstacles, are receiving more and more attention. Viaducts are generally built at higher positions and directly exposed to the natural environment. Therefore, their structural safety is easily affected by various natural factors, among which wind factors are particularly prominent. The use of BIM technology can build an accurate three-dimensional digital model, which contains the geometric, physical and functional information of the bridge, and provides an accurate data basis for wind monitoring agencies. In windy weather, in order to ensure the safe operation of the viaduct, the wind is also monitored in real time. In the existing technology, fan blades are used in conjunction with sensors to monitor the wind size in real time. Since the fan blades have inertia during rotation, when the wind becomes smaller, the inertia of the fan blades themselves will cause errors in the transmission signal received by the sensor, affecting the accuracy of the monitoring data. In view of this, a viaduct wind monitoring mechanism based on BIM technology is proposed. Utility Model Content

[0003] In order to solve at least one of the above-mentioned technical shortcomings, the utility model provides an elevated bridge wind monitoring mechanism based on BIM technology, including a mounting plate, a slidable wind measuring tube is connected to one side of the mounting plate, and a shell is arranged above the mounting plate, and a sensor is arranged above the shell.

[0004] Furthermore, a hemispherical air inlet surface is provided on one side of the wind measuring tube.

[0005] Furthermore, the wind measuring tube has a hollow structure.

[0006] Furthermore, liquid pipes arranged in a semicircular array are arranged above the shell, and matching monitoring liquid is arranged in the liquid pipes, and the inner wall of the liquid pipe is arranged tangent to the sensor.

[0007] Furthermore, a bottom extension tube connected to the liquid pipe is also provided at the bottom of the shell, a matching limit plate is provided on one side of the bottom extension tube, and the bottom extension tube is plugged into the wind measuring tube.

[0008] Furthermore, the inner diameter of the bottom extension tube is equal to the inner diameter of the disc at the head end of the wind measuring tube.

[0009] Furthermore, the sensor is a liquid level sensor, and the sensor is signal-connected to a terminal control device of the BIM.

[0010] Beneficial effect: A groove welded to the bottom of the shell is provided on the top of the mounting plate, and the mounting plate is installed at a suitable installation position of the viaduct by bolts. When wind comes from one side of the shell, the corresponding wind measuring tubes in the two sets of mirror-mounted wind measuring tubes will pass through the wind force in that wind direction, causing the wind inlet surface to be affected by wind resistance and move inward at the inner end of the bottom extension tube to cause the monitoring liquid in the liquid tube to rise, and transmit the data to the BIM terminal under the detection of the sensor, so as to achieve real-time monitoring of different wind directions.
