As shown in Figure 1, a kind of hinge type wind barrier for high-speed railway bridge of the utility model embodiment, comprise at least two root posts 1, between column 1, leave spacing, column 1 bottom fix on the ground or base on, between adjacent two root posts 1, be provided with at least one in order to stop the assembly 2 that keeps out the wind of beam wind, the assembly 2 that keeps out the wind comprises that two in order to stop the blade 201 and in order to connect the connecting axle 202 of two blades 201 that keep out the wind of keeping out the wind of beam wind, the edges of boards of two blades 201 that keep out the wind connect in groups by connecting axle 202, at least a slice keep out the wind blade 201 can be along connecting axle 202 rotation.The utility model is for the hinge type wind barrier of high-speed railway bridge, by the mode of the assembly that keeps out the wind is set between two adjacent upright, utilize the rotating folding adjustable hinge formula wind barrier of two blades that keep out the wind and contact surface form and the ventilative rate of beam wind of the assembly that keeps out the wind.The blade that keeps out the wind changes rotating folding angle according to the wind-force size of beam wind, and during in the face of little air quantity beam wind, the blade that keeps out the wind that closes up state by rotation low-angle carries out changing ventilative time beam wind flow direction; During in the face of Wind Volume beam wind, two blade rotaries that keep out the wind are to the state being completely integrated, beam wind directly sees through by the gap of keeping out the wind between assembly, reduce Wind Volume beam wind for the wind action power of hinge type wind barrier, thereby reduce the effect that hinge type wind barrier passes to bottom bridge c, ensure the normal design of bridge c and operation, reduce the extra cost that opposing beam wind causes.
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5 and Fig. 6, it is also, connecting axle 202 two ends are connected on the column 1 of end.
It is also, is provided with in order to control the controller of keep out the wind blade 201 anglecs of rotation and rotary speed on connecting axle 202 and/or the blade 201 that keeps out the wind.
It is also, is provided with to respond to the wind sensor of wind-force on the assembly 2 that keeps out the wind; Wind sensor connects controller.
It is also, connecting axle 202 and/or the blade 201 that keeps out the wind are provided with the position-limit mechanism in order to the spacing distance between blade 201 ends and column 1 of keeping keeping out the wind.
It is also, the blade 201 that keeps out the wind is all laid along the direction perpendicular to column 1; Or keep out the wind blade 201 all with column 1 oblique.
It is also, the assembly 2 that keeps out the wind is provided with in order to the keep out the wind angle positioning of blade 201 anglecs of rotation of restriction.
It is also, angle positioning is at least one in alignment pin, locating clip, retainer spring, spring hinge, Location resilient piece.
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5 and Fig. 6, it is also, column 1 is along arranged in a straight line, and the arrangement straight line of column 1 is parallel with the rail on railroad bridge.
It is also, column 1 comprises the first column of arranging near rail and the second column of arranging away from rail.
It is also, the first column and the second column are intervally arranged.
During enforcement, by adjusting blade 201 anglecs of rotation of keeping out the wind, change the size of ventilative rate.Because its form is as butterfly hinge, herein by its called after " hinge-shaped wind barrier " (Hinge-Type Wind Barriers).
The utility model is for the hinge type wind barrier of high-speed railway bridge, and two blades 201 that keep out the wind are connected by hinge (connecting axle 202), and relatively rotate and change ventilative area with this around same axle, and rotation angle range is 0 °-90 °.When blade 201 anglecs of rotation of keeping out the wind are 0 °, be assumed to original state, be equivalent to arrange airfast wind barrier, now ventilative rate is 0, stops that incoming flow effect is maximum; When the angle of cut is 90 °, be equivalent to arrange horizontal paling form wind barrier, now in full open position, ventilative rate is maximum, and most incoming flows all can see through, and are conducive to high wind and do the protection of used time to wind barrier and bridge.Because the blade that keeps out the wind has certain thickness, its end is made into slope and can guarantees to pivot unimpeded, can close completely.Whole barrier, is arranged at a certain distance the rotatable blade 201 that keeps out the wind is installed between 1, two column 1 of column by anchor connection on the bridge floor edge of a wing.
This device is also to realize the object that changes wind barrier height by changing keep out the wind blade 201 height and blade 201 quantity of keeping out the wind of monolithic.Be to change angle and reach the object that changes ventilative rate and airflow direction water conservancy diversion.
The utility model is for the hinge type wind barrier of high-speed railway bridge, by the variation of the anglec of rotation, can also change the angle of cut of incoming flow and blade, fluid out of plumb act on keeps out the wind on blade 201, and produce contrary vertical velocity between two hinges (assembly 2 keeps out the wind), this partial velocity will be offset, consumption kinetic energy has reduced impact, has reduced the impact of incoming flow to wind barrier.
The utility model, for the hinge type wind barrier of high-speed railway bridge, has reduced the speed of fluid after wind barrier, thereby has reduced the impact to train, and it is better that aeroperformance is compared common wind barrier.
Can change blade angle according to the wind speed of incoming flow and the wind angle of attack etc., can be divided into active and two kinds of modes of passive type.For example, by establish monitoring wind field device at work point place, obtain wind field data, or on wind barrier sensor installation, and send data to electronic intelligence system and control the modes such as blade angle and realize ACTIVE CONTROL, be called active; Or forming spring hinge at axis of rotation mounting spring device, the mode that the wind-force by incoming flow directly blows top blade changes the modes such as blade angle and realizes passive rotation, is similar to the operating principle of swinging door, is called passive type.
When the anglec of rotation is little compared with hour ventilative rate, can stop to greatest extent incoming flow, be the running environment of a low wind speed of train creation.When the anglec of rotation is larger, allow incoming flow major part to see through, on bridge, during train operation or under high wind state, reduce the wind load of bridge and the wind load of wind barrier itself.
H is wind barrier height, and h is the blade height of keeping out the wind, and b is the vane thickness that keeps out the wind, and β is the anglec of rotation, and L is the spacing between column.These parameters all can be adjusted in conjunction with correlative study according to actual track.
The utility model is applicable to all kinds of high-speed railway bridges, particularly Longspan Bridge.Can improve this aeroperformance in strong wind of running train, bridge and barrier, improve the force-bearing situation of bridge construction and accessory structure thereof, barrier structure, improve fatigue life, improve the service level of whole rail track.
The utility model belongs to one of primary study content of project of national nature science fund project (51178471,51322808), for running train aeroperformance and safety traffic provide more accurate wind tunnel test means, thereby for the technical support that provides of bullet train safe operation is provided.
The foregoing is only preferred embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure transformation that utilizes the utility model description to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
