Detailed description of the invention
Below in conjunction with accompanying drawing illustrated embodiment, invention is illustrated further.
The rate of keeping out the wind of air partition is defined as the ratio of Windbreak barrier strip side elevation projected area and the gross area, keep out the wind rate α=(∑ hi)/(∑ hi+ ∑ di), as shown in fig. 1, wherein i is the number of blade (or barrier bar) of keeping out the wind, difference according to external environment, air partition can be regulated keep out the wind rate by hindering the rotation of bar, thus meeting the different requirements of bridge floor driving wind environment and bridge entirety aeroperformance.
Fig. 1 is the track structure of the present invention adjustable air partition structure of a kind of rate of keeping out the wind, and Fig. 2 show another kind embodiment rotary shaft structure of the present invention.As it can be seen, including: left column 101, right column 102 etc. and middle standing pillar 1, described each column can adopt rigid material to make, and is used for supporting swing arm two ends；The some swing arms 2 installed on described each column can adopt the material such as steel or alloy to make, and from the web traverse of column, is used for driving the rotation of the barrier bar 3 being fixed on swing arm；Barrier bar 3 can adopt the transparent materials such as steel, alloy material, transparent or semitransparent macromolecular material, glass plate to make；The power of system is provided by motor 4, is connected to supervisory control desk by controlling electric current wiring 5.
Need and motor power size according to design, can using two or more air partition unit adjacent between the first column 11 with the second column 12 as a basic rotating unit, controlling the rotation of air partition bar in this rotating unit by the actuating device being arranged in middle standing pillar 1, the attachment structure between adjacent rotated unit is as shown in Figure 5.
Furthermore, Figure 1A, B show an embodiment of the present invention caterpillar drive structure air partition schematic diagram, each of which root swing arm 2 centered position is provided with driven gear, the swing arm of gear both sides is fixed one section, two sections respectively or multistage barrier bar, each swing arm 2 and the barrier bar being fixed thereon constitute a basic rotating unit.
Some swing arms are erected in the web of column of both sides in parallel to each other, and the gear of each swing arm is arranged in the column 1 of centre.
Wherein drive mechanism 6 is composed as follows: each driven gear (includes gear 601) and is fixedly connected on swing arm or the motor of correspondence position, link together by crawler belt 602 and be accommodated in middle standing pillar 1 between each driven gear, rotated by motor driving bottom gears during use, realize rotating and then drive each swing arm accordingly and hindering the rotation of bar of each driven gear by crawler belt 602.
Owing to each driven gear drives by crawler belt 602, crawler belt 602 moves a segment distance, when the driven gear size on each swing arm and the number of teeth are identical, and each swing arm and the barrier rotatably identical angle of bar；When each driven gear size on swing arm or number of teeth difference, each swing arm and the barrier rotatably different angle of bar；Visible, the control to each air partition finite element rotation angle can be realized by arranging driven gear size on each swing arm or the number of teeth.
Fig. 2 is another kind embodiment rotary shaft drive mechanism air partition schematic diagram of the present invention, wherein drive mechanism 7 space and plan positional relationship are respectively as shown in figures 3 a and 3b, each driven gear (includes driven gear 701) and is fixedly mounted on the swing arm of correspondence, central rotating shaft 703 is arranged in column, can on chassis free moving.Corresponding each cyclic position has a driving gear respectively, and be meshed with the driven gear on the swing arm of relevant position, such as one of them driving gear 702 is arranged on central rotating shaft 703 and is meshed with driven gear 701, is arranged at the driving gear bottom central rotating shaft 703 and is meshed with the gear at motor place.During use, motor drives the rotation of central rotating shaft 703 by the engaged transmission of bottom gears, drives each driven gear (including driven gear 701) to rotate by the rotation of central rotating shaft 703；It is clear that can pass through arranging of intermeshing each driving gear and the size of driven gear and the number of teeth is realized each swing arm and be arranged at and hinder, on swing arm, the control that bar rotational angle is consistent or inconsistent.
In another embodiment, respectively as illustrated in figures 4 a and 4b, the separate type that can realize hindering up and down bar by the rotary shaft drive mechanism of shown improvement rotates for the rotary shaft drive mechanism locus of improvement and engaged transmission relation.In the structure shown here, driving gear, driven gear are fixed on central rotating shaft 703 and swing arm 2 equally respectively, central rotating shaft 703 is rotated with the realization of engaging of motor gear by bottom, it is different in that: driven gear and the driving gear of each position corresponding are in released state in an initial condition, it is necessary to by transition gear, mechanism realizes transmission；Such as, transition gear 704 is respectively at released state in an initial condition with driven gear 701 and driving gear 702, and transition gear 704 connects with corresponding telescopic cantilever device 705 and triggering device 706 and coordinates.Telescopic cantilever device positioned 705 and triggering device 706 are arranged on column；Trigger device 706 and be connected to supervisory control desk by controlling electric current wiring 5.
Trigger device switch under original state to be closed, namely each transition gear and driving gear, driven gear are in released state, barrier bar does not rotate, when need the barrier bar regulating some position keep out the wind rate time, namely these location triggered devices switch is opened, such as, after opening the switch triggering device 706, trigger elastic device in device and forward thrust is provided, the telescopic cantilever device positioned 705 driving this position forward extends out, and the position of transition gear 704 is pushed ahead the driven gear 701 with this position and driving gear 702 is simultaneously engaged.In this state, the power that motor 4 provides can drive the rotation hindering bar on driven gear 701 and this swing arm by gear engagement, and then regulates rate of keeping out the wind.When triggering device 706 and closing, trigger elastic device retraction in device 706, thus cantilever arrangement 705 is shunk, transition gear 704 separates with driven gear 701 and driving gear 702, the power that motor 4 provides is not transferred on driven gear 701, the swing arm connecting driven gear 701 will not rotate, and the air partition on this swing arm is without rotation.Same, arranging of the size to intermeshing each driving gear, driven gear and transition gear and the number of teeth can be passed through and realize the control that each swing arm and the barrier bar rotational angle that is arranged on swing arm is consistent or inconsistent.
Fig. 5 is bispin knock-off joint position view between the embodiment of the present invention adjacent air partition rotating unit, corresponding adjacent two the air partition rotating units of bispin knock-off joint.
Fig. 6 A, B, C, D illustrate several cross-sectional structures that column 1 can adopt, and are square-tube type, grooved, π type and T-shaped respectively.
