The shape of the second barrier rib 401 is identical to that of the first barrier rib 301, and will not be described here.
The arrangement is that when wind blows to the first barrier blade 301, the wind blows to the second plate 3012 first and then gradually flows to the second plate 3012 and the third plate 3013, so that wind force is effectively reduced, the surface areas of the first barrier blade 301 and the second barrier blade 401 are large, the barrier effect on wind is facilitated, the wind force is reduced, and the stability of the first wind barrier 3 and the second wind barrier 4 is improved.
Optionally, the surface of the first barrier leaf 301 is provided with a plurality of ventilation holes 3015.
Referring to fig. 2, 3, 6 and 7, a plurality of ventilation holes 3015 are formed on the surfaces of the first barrier blade 301 and the second barrier blade 401, and the first barrier blade 301 and the second barrier blade 401 are arranged in a net structure by the plurality of ventilation holes 3015. The shape of the vent 3015 is one or more of round, waist-shaped, oval or square, in this embodiment, the vent 3015 is a combination of holes with various shapes, and the size of the vent 3015 is also provided with various specifications.
In this way, when natural wind blows on the first barrier blade 301 or the second barrier blade 401, the first barrier blade 301 and the second barrier blade 401 slow down the wind speed, and when wind blows on the bridge deck through the vent 3015, the wind speed is greatly reduced, and the running train is not easily affected. Meanwhile, as the ventilation holes 3015 are used for allowing natural wind to pass through, the bearing of the first barrier blades 301 and the second barrier blades 401 is reduced, the stability of the first barrier blades 301 and the second barrier blades 401 is improved, and the service lives of the first barrier blades 301 and the second barrier blades 401 are prolonged.
In the description of the present application, it should be understood that, in the drawings, the forward direction of "X" represents the right direction, the reverse direction of "X" represents the left direction, the forward direction of "Y" represents the front direction, the reverse direction of "Y" represents the rear direction, the forward direction of "Z" represents the upper direction, the reverse direction of "Z" represents the lower direction, and the directions or positional relationships indicated by the terms "X", "Y", "Z", etc. are those based on the description of the drawings, and are merely for convenience of description and simplification of description, rather than for indicating or implying that the device or element to be referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as limiting the present application. Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.
In the description of the present application, it should be noted that the azimuth or positional relationship indicated by the terms "upper", "lower", etc. are based on the azimuth or positional relationship shown in the drawings, and are merely for convenience of describing the present application and simplifying the description, and are not indicative or implying that the apparatus or element in question must have a specific azimuth, be constructed and operated in a specific azimuth, and thus should not be construed as limiting the present application. Unless specifically stated or limited otherwise, the terms "mounted," "connected," "coupled," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected, mechanically connected, electrically connected, directly connected, or indirectly connected via an intervening medium, or may be in communication between two elements. The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art according to the specific circumstances.
It should be noted that in the present application, relational terms such as "first" and "second" and the like are used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Moreover, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one does not exclude the presence of other like elements in a process, method, article, or apparatus that comprises an element.
The foregoing is only a specific embodiment of the application to enable those skilled in the art to understand or practice the application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the application. Thus, the present application is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
