Staggered wind-shield walls capable of controlling wind speed

Abstract

The invention relates to staggered wind-shield walls capable of controlling the wind speed. The staggered wind-shield walls comprise a plurality of wind-shield wall bodies arranged among buildings, the multiple wind-shield wall bodies are arranged in a mutually staggered mode, a channel is reserved between every two adjacent wind-shield wall bodies, a wind speed regulating device capable of regulating the wind speed is arranged on each wind-shield wall body, each wind speed regulating device comprises a hollow frame, a plurality of rotating shafts rotatably connected to the frame and a drivingdevice driving the rotating shafts to rotate, and each rotating shaft is fixedly connected with a main body regulating tube. Therefore, according to the staggered wind-shield walls capable of controlling the wind speed, the main body regulating tubes are rotated through the rotating shafts, the angles of the main body regulating tubes are changed, and gaps between the main body regulating tubes can be opened or closed arbitrarily to adjust the degree of porosity between the main body regulating tubes in different wind environments, so that the optimal wind speed is ensured optimally by the wind-shield walls.

Description

technical field [0001] The invention relates to the field of disaster prevention construction engineering, in particular to a wind-speed-controllable staggered windshield wall. Background technique [0002] The layout of urban buildings in various ways affects the changes in the surrounding wind direction and flow velocity. The building wind environment not only affects the air quality, but also involves the safety and comfort of pedestrians. A complex of high and low buildings can easily form an artificial "street canyon", resulting in a canyon effect, resulting in an increase in local wind speed and endangering the safety of pedestrians. Traditional fence devices are generally fixed and play a certain role in enclosure, but they are not very effective in blocking the wind flow field. The experimental research shows that the porosity (the ratio of the pore area to the total area) has a significant effect on the average velocity field distribution of the flow around the fen...

Problems solved by technology

[0003] Now there are local high wind speeds in the aisles between high-rise residential buildings, and vegetation is generally used to block the property. Although it will reduce the wind speed to a certain extent, it is not conducive to the growth of vegetation, and the branches of vegetation may also be harmful to pedestrians. There are certain potential safety hazards, and the planting of vegetation requires a certain space, which reduces the scope of normal activities of residents
