Wind barrier
Technical Field
The utility model belongs to the field of traffic protection facilities, and particularly relates to a wind barrier.
Background
Tunnels and highways are important components of modern traffic infrastructure. However, under certain geographical and meteorological conditions, intersections, tunnel entrances, mountain highways, etc. are often severely affected by wind. In the running process of the high-speed train, the high-speed train is easily influenced by the action of lateral wind, the running of the train is unstable under the action of strong lateral wind, the derailment phenomenon of the train can be seriously caused, and the concept of a wind barrier is introduced for relieving the adverse effects.
The existing wind barriers are mostly applied to the field of bridges, and the wind barriers are relatively less researched when high-speed trains encounter a serious crosswind phenomenon through tunnel exits. Most of the existing wind barriers are fixed, namely, the porosity of the wind barriers is unchanged along the advancing direction of a train, but when the train runs at a high speed, the air resistance of the train can be increased along with the increase of the air resistance, so that the energy consumption is increased, and the running efficiency is reduced. On the other hand, stationary wind barriers are often made of durable materials, but may still require regular inspection and maintenance in case of external impact or severe weather conditions, which may be difficult. The requirements of light weight and construction convenience cannot be met, so that engineering cost is reduced, and fixation is not stable and rapid enough.
Therefore, it is necessary to provide a wind barrier suitable for solving the problems in the prior art, improving the convenience of construction of the wind barrier and reducing the cost, and providing a safer, more stable and more efficient traffic environment.

Detailed Description
Embodiments of the utility model are described in detail below with reference to the attached drawings, but the utility model can be implemented in a number of different ways, which are defined and covered by the claims.
Examples:
Referring to fig. 1 and 2, the wind barrier comprises wind barrier units 2 arranged on two sides of a road 1, wherein each wind barrier unit 2 comprises a plurality of upright posts 2.1 and a plurality of wind shields 2.2, the upright posts 2.1 are arranged on the ground at intervals along the length direction of the road 1, two adjacent upright posts 2.1 are connected through the wind shields 2.2, a plurality of mounting holes 2.3 are arranged on the upright posts 2.1 at intervals along the vertical direction, and two ends of each wind shield 2.2 are connected with two adjacent upright posts 2.1 through the mounting holes 2.3.
Through the interval setting mounting hole, the deep bead passes through the mounting hole stand and connects, has guaranteed the stability of connecting between the stand, and is convenient to connect, can also save material. The wind barrier with good stability is convenient to be quickly arranged on two sides of the road.
The setting of a plurality of mounting holes is convenient to set up the deep bead of different quantity subsequently, cooperates the structure of above-mentioned deep bead to even if need different air permeability, also need not to reprocess deep bead and stand, convenient quick construction and installation, application scope is wide.
The number of wind deflectors 2.2 varies between different uprights 2.1 and the number of wind deflectors 2.2 increases or decreases along the length of the road 1. The number of wind deflectors 2.2 between the plurality of uprights 2.1 is set in order of 20%, 40%, 60% and 80% air permeability. The ventilation rate between the upright posts is controlled by controlling the number of the wind shields, so that the wind barrier can be quickly and conveniently provided with gradual ventilation rate, and the gradual ventilation rate is beneficial to improving the wind prevention effect of the wind barrier and guaranteeing the service life of the wind barrier.
Due to the adoption of the gradual change type air permeability design, in the running process of the train, gradually increased air flow is allowed to pass through, the blocking of the wind barrier to the wind field is reduced, and the windproof effect is improved.
