For achieving the above object, the technical scheme that the utility model adopts is following:
A kind of 35 kilovolts of outdoor bus bridges; Interconnected by a plurality of independent pontics and to form, each pontic includes cuboid pontic skeleton, said pontic skeleton the periphery backplate of six direction is set; The backplate of said six direction all adopts the aluminum metal material to make; On the relative position a plurality of ventilation holes are set respectively on the top backplate of said pontic skeleton and the end backplate, the centre position of said top backplate offers square aperture, and the edge that is higher than backplate surface, said top is set around the said square aperture; Top, said edge covers and is provided with lamina tecti; Said edge is provided with a plurality of ventilation holes, and the two ends of said top backplate exceed the upwards turnover of the part that is connected with side guard plate, adjacent two pontics and when connecing; Between adjacent two side guard plates of two pontics rubber blanket is set, the top backplate of adjacent two housings upwards turns down partial fixing and buckle is set above that.
Said lamina tecti through nutplate and bolt on the backplate of said top.
Be provided with sealing device between the edge of said lamina tecti and square aperture.
The inside and outside spray of the backplate of said pontic is provided with outdoor molding powder, and degree of protection can reach IP54.
Ventilation hole on the backplate of the said end is a counterbore.
The configuration design of the utility model pontic is flexible, and the pontic of aluminium material is in light weight, is convenient to installation and maintenance; The pontic rapid heat dissipation can the restricted internal temperature rise; The pontic degree of protection is high, can protect internal bus equipment to avoid the influence of extraneous adverse circumstances; Structural strength is high, and corrosion resistance is strong, long service life.

Fig. 3 is adjacent pontic of the utility model and the sketch map that connects;
Fig. 4 is the partial enlarged drawing of buckle part among Fig. 3;
Fig. 5 is the partial enlarged drawing that lamina tecti is connected with the square aperture edge among Fig. 1.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described in detail:
Like Fig. 1-shown in Figure 5, interconnect by a plurality of independent pontics in the present embodiment and form, each pontic includes cuboid pontic skeleton, said pontic skeleton the periphery backplate of six direction is set.The single-unit pontic is of a size of the high 900mm of the wide 1900mmX of long 975mmX, satisfies the outdoor insulative distance and is the requirement of 400mm, adopts full aluminium material processing, and single-unit pontic weight is 70Kg, is convenient to fixed installation, and its external form can be adjusted according to field condition.
When bus bridge normally moved, under the common influence of weather, illumination and bus temperature rise, bus bridge body and internal temperature rose very fast, and internal pressure raises fast.On the relative position a plurality of ventilation holes are set respectively on the top backplate 2 of said pontic skeleton and the end backplate 4; Ventilation hole on the backplate of the said end 4 is a counterbore, and the ventilation hole on the top backplate 2 can make the pontic internal pressure obtain rapid release, and the ventilation hole on the end backplate 4 can get into the fresh air in the environment; The inner air and outer air convection current; Thereby temperature in the reduction bridge, the ventilation hole on the end backplate 4 is a counterbore, even if owing to reasons such as condensation cause ponding in the bridge; Also can discharge smoothly, guarantee the safe operation of bus bridge.
Simultaneously, made full use of the characteristics that aluminum metal is inhaled rapid heat dissipation, on the one hand internal high temperature has been transferred on the pontic fast by bus, pontic and external environment are carried out heat transmission fast on the other hand, thereby guarantee that temperature is unlikely too high in the bridge; Because aluminum metal is the non-conductor of magnetic, also limits the vortes interference of current carrying bus to pontic to a certain extent, it is very high not cause bus bridge pontic temperature to rise.
The centre position of said top backplate 2 offers square aperture; The edge that is higher than said top backplate 2 surfaces is set around the said square aperture; Top, said edge covers and is provided with lamina tecti 3, and said lamina tecti 3 is fixed on the said top backplate 2 through nutplate 5 and bolt 6, is provided with sealing device 7 between the edge of said lamina tecti 3 and square aperture; Can adopt the ternary third foaming sealing strip, realize the compactness that is connected between lamina tecti 3 and the top backplate 2.Said edge is provided with a plurality of ventilation holes 10, even sleety weather, water can not got in the bridge by ventilation hole 10 yet.The split design of square aperture and lamina tecti 3; In the passage that confession maintainer turnover is provided; Guaranteed the compactness that contacts between lamina tecti 3 and the square aperture; Naturally reserve gap, the 6mm left and right sides between lamina tecti of placing 3 and the square aperture edge, be convenient to bolted after covering naturally, can make the pontic shell satisfy its anti-rainwater, anti-dust storm requirement.
The two ends of said top backplate 2 exceed the upwards turnover of part that is connected with side guard plate 1; And turning up the punching of face middle and upper part; Adjacent two pontics and when connecing; Between adjacent two side guard plates of two pontics rubber blanket 8 is set, the top backplate 2 upwards turnover parts of adjacent two housings are through bolt and buckle 9 is set above that, thereby can prevent that rainwater from being infiltrated by faying surface between two joint bridges.
The utility model has been taken all factors into consideration the influence of outdoor environment to bus bridge and inner current carrying bus; Aspect crossstructure intensity; The pontic skeleton adopts the aluminium angle steel of 50*50*5 to be welded; Backplate adopts 3.0 aluminium sheets and skeleton to carry out full weld and handles, and overall construction intensity can be born internal bus equipment and maintainer's weight fully simultaneously.Behind the welding forming, the outdoor molding powder of spray can effectively be resisted the erosion of extraneous adverse circumstances to pontic inside and outside the pontic backplate.In addition, because aluminum metal has extremely strong non-oxidizability, the lacquer painting even pontic is damaged in transportation and installation process can not produce significantly pontic yet and corrode, and degree of protection can reach IP54.
In sum, the utlity model has characteristics such as monnolithic case is attractive in appearance, structural strength is high, degree of protection is high, long service life.
Certainly; Above-mentioned explanation is not to be the restriction to the utility model; The utility model also be not limited in above-mentioned for example, variation, remodeling, interpolation or replacement that the technical staff in present technique field is made in the essential scope of the utility model also should belong to the protection range of the utility model.
