However, traditional wind barriers are often static and cannot be adjusted, that is, the air permeability can only remain unchanged, and although some can be adjusted, it is very inconvenient to adjust. When encountering rare strong winds, the opening rate needs to be reduced to 0, and when there is no wind, the opening rate can be adjusted to the maximum. Therefore, traditional wind barriers cannot achieve the goal of conveniently and intelligently adjusting the air permeability, which is easy to cause many problems such as train driving safety issues and wind barrier fatigue damage.

[0028] The embodiments of the present invention are described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered by the claims.

[0029] Example:

[0030] A dynamically adjusted wind barrier device, reference Figure 1 A dynamically adjustable wind barrier device includes a wind barrier assembly arranged on both sides of a road; the wind barrier assembly includes a plurality of wind barriers 8 arranged in series; the wind barrier 8 is provided with a plurality of ventilation holes, and a blade 6 is rotatably arranged in the ventilation hole, and the blade 6 is used to open and close the ventilation hole. By rotating the blade, the ventilation hole can be completely opened perpendicular to the wind barrier, or the blade is located in the same plane as the hole of the wind barrier, so as to completely close the ventilation hole, thereby conveniently adjusting the air permeability of the wind barrier to adapt to different wind speed weather to ensure the driving safety of the train.

[0031] The ventilation holes are arranged in multiple rows on the wind barrier 8, and the ventilation holes in the same row overlap along their central axis in the vertical direction; the wind barrier 8 is also rotatably provided with multiple shafts 5 in the vertical direction, and the shafts 5 simultaneously pass through multiple ventilation holes in a row, so that the shafts 5 are fixedly connected to the blades 6 in the ventilation holes in the row and drive the blades 6 to rotate, see Figures 2 to 4 The blades in a whole row of ventilation holes are driven to rotate by the rotating shaft at the same time, so that the air permeability of the wind barrier can be adjusted quickly and conveniently, and the opening and closing degrees of ventilation holes in different rows can be kept different to adapt to complex crosswind conditions.

[0032] The ventilation hole is circular, and the blade 6 is circular to match the ventilation hole.

[0033] The wind barriers 8 are connected by the columns 2, and the wind barriers 8 are detachably mounted on the columns 2. The lower end of the columns 2 is provided with a base 1 for supporting the columns 2. The columns are used to detachably connect two adjacent wind barriers, which is convenient for use and for setting different numbers of wind barriers according to the situation. The base then stably fixes the columns on the ground.

[0034] The upper and lower ends of the columns 2 are further provided with cross beams 3 for connecting two adjacent columns 2, and the wind barrier 8 is fixedly arranged between the upper and lower cross beams 3 by bolts. The cross beams can effectively provide stability for the wind barrier.

[0035] The wind shield 8 includes a plurality of independent wind shields 4, which are detachably connected by rivets to form wind shields 8 of different lengths. By forming different wind shields with wind shields, the length of the wind shield assembly on one side can be finely adjusted.

[0036] See also Figure 1 and Figure 5 In this embodiment, a wind speed sensor 7 is also included, and the wind speed sensor 7 is arranged on the side of the wind barrier 8 unit away from the road. At least three wind speed sensors 7 are evenly arranged along the road direction. A collector, a control system and a motor are also included; the control system and the wind speed sensor 7 are electrically connected to the collector; the control system is electrically connected to the motor. The wind speed sensor is connected to the collector through a cable, and the wind field data is stored in a memory card inside the collector and input into the controller. The controller then outputs a corresponding signal of whether to adjust and how to adjust the blade angle of the wind barrier, and then the motor rotates the shaft to adjust the angle of the blade according to the signal of how to adjust the blade angle of the wind barrier, thereby adjusting the air permeability of the entire wind barrier.

[0037] The controller selects the wind field information on the most unfavorable side, removes the unreasonable data on this side, averages the remaining data, and outputs the average data as a motion signal to control the motor to adjust the blade angle, thereby realizing intelligent rotation of the blade.

[0038] The relationship between wind speed and blade opening angle is fitted using a linear function. In case of complex terrain conditions, other functional relationships can be used for fitting. The principle of fitting is to prevent crosswinds from posing a threat to the safety of high-speed train driving.

[0039] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
