Embodiment Construction
[0035] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0036] The first embodiment of the present invention proposes a self-supply control system for adjusting the wind resistance performance of steel structure bridges, such as figure 2 As shown, multiple groups of hydraulic deflectors 2 are arranged at specified intervals at the bottom 1 of the steel structure bridge. In this embodiment, the deflectors 2 are arranged in an arc-shaped structure, which can reduce the space occupied by the deflectors and improve the wind passing efficiency at the same time. The deflector is controlled by a hydraulic control mechanism.
[0037] Such as figure 1 As shown, the control system of the present invention includes a wind force monitoring unit, a vibration monitoring unit, and a data processing module;
[0038] The wind monitoring unit is used to monitor the current wind environment of the steel structu...

The invention discloses a self-supply control system for wind resistance performance adjustment for a steel structure bridge, which belongs to the technical field of bridges. The bottom surface of thesteel structure bridge is provided with multiple groups of hydraulic guide plates at a specified interval, and the guide plate is controlled by a hydraulic control mechanism. The control system comprises a wind monitoring unit, a vibration monitoring unit and a data processing module, wherein the wind monitoring unit is used for monitoring the wind environment where the current steel structure bridge is located; the vibration monitoring unit is used for monitoring the vibration environment of the current steel structure bridge; and the data processing module is used for receiving data transmitted by the wind monitoring unit and the vibration monitoring unit and performing determination, and when the wind value of the current environment exceeds a threshold value, an angle signal for adjusting a rotation angle is sent to the hydraulic control mechanism. The whole bridge wind resistance structure of the system is simple, and through accurate control on the guide plate, the wind resistance performance of the steel structure bridge can be effectively improved.
Description
technical field [0001] The invention belongs to the technical field of steel structure bridges, in particular to a self-supply control system for adjusting the wind resistance performance of steel structure bridges. Background technique [0002] Steel structure bridges play an irreplaceable role in transportation, but the inspection and maintenance workload of bridges is extremely huge. On the one hand, the proportion of old bridges in my country is very large. These bridges have low design standards at the beginning, and at the same time lack the necessary Maintenance and repair, its aging phenomenon is becoming more and more serious, and the carrying capacity is significantly reduced, which gradually cannot meet the needs of modern transportation development. On the other hand, with the development of industrial construction, the frequency of transporting extra-large and extra-heavy equipment on roads and railways has been greatly increased. When those overweight vehicles pa...
