The outdoor intelligence monitoring and controlling device casing of special line for passenger trains
Technical field
The utility model relates to a kind of casing, specifically, relates to the casing of the outdoor intelligence monitoring and controlling device on a kind of special line for passenger trains.
Background technology
Special line for passenger trains is special high-grade railway; speed is fast; therefore require the various device performance high and stable; particularly be installed in outdoor electronic equipment; be in for a long time under high temperature or low temperature, rainwater, high humility, the fast strongly disturbing adverse circumstances of burn into; in order to guarantee the reliability service of electronic equipment, need make strict specification requirement to carrier (being outdoor case) is installed, could really realize the defencive function that electronics is provided with like this.
At above-mentioned situation, at present, common solution has two kinds: one. and adopt cold-rolled steel sheet to be welded, form the individual layer casing.Two. adopt the bending of double side zinc coating steel plate to be welded into outer container, built-in independent case body combines high-grade outdoor case.All there are various defectives more or less in above-mentioned two schemes, and scheme one is simple in structure, and is cheap, but can not well adapt to wild environment, can not realize the protection to electronic equipment well; Though it is effective that scheme two is protected, complex structure, and involve great expense, be not suitable for a large amount of uses.
The utility model content
The purpose of this utility model is to provide a kind of special line for passenger trains outdoor intelligence monitoring and controlling device casing, solves problems of the prior art, under the prerequisite that guarantees the protection effect, simplifies body structure, reduces production costs.
To achieve these goals, the technical solution adopted in the utility model is as follows:
The outdoor intelligence monitoring and controlling device casing of special line for passenger trains, it is characterized in that, comprise shell, be arranged at the inner casing of enclosure, and be arranged at be used on the inner surface of outer cover to support and fixedly inner casing be connected and fixed plate, on shell, also be provided with the cover plate that is used for closure.
Described cover plate flexibly connects by hinge and shell.
The edge of described cover plate also is provided with waterproof adhesive tape.
The inner surface of described cover plate also is provided with pressing plate, and is provided with sealing gasket between pressing plate and cover inner surface, and described sealing gasket is made by heat barrier foam.
The outer surface of described shell is provided with at least one mounting panel.
The copper earthing rod is set respectively on described shell and the inner casing.
Also be respectively equipped with water joint on described shell and the inner casing.
The described plate that is connected and fixed is made by the earlier oblique respectively crooked down edge direction bending parallel with bonding jumper again in the two ends of a bonding jumper.
The utility model utilization air is the non-conductor principle of heat, designed the structure that inside and outside double Shell is separated, and the mode of heat insulation and water resistance layer, adopt rational technology, make casing have characteristics such as excellent waterproof, heat insulation and dissipation, insulation, anticorrosion, anti-interference, easy installation.
The utility model is mainly used in the protection of the electrical outdoor subset of special line for passenger trains, has simple in structurely, easy for installation, and production cost is low, protects effective advantage, has very high practical value.

Embodiment
As Fig. 1~shown in Figure 3, the outdoor intelligence monitoring and controlling device casing of special line for passenger trains comprises shell 1, is arranged at the inner casing 2 of shell 1 inside, and be arranged at be used on shell 1 inner surface to support and fixedly inner casing 2 be connected and fixed plate 3, on shell 1, also be provided with the cover plate 4 that is used for closure 1.
Described shell 1 is welded by aluminum alloy materials bending, the outdoor molding powder of surface plastic spraying, in establish copper earthing rod 10, its function is: splendid attire inner casing 2, inner casing 2 is thoroughly separated with the external world, reach waterproof, protection against the tide, heat insulation, heat preservation effect.Described inner casing 2 also is welded by the aluminum alloy materials bending, in establish copper earthing rod 10, the surface sand-blasting oxidation, its function is: electronic equipment and related accessory are installed.
Described cover plate 4 also is welded by the aluminum alloy materials bending, is provided with reinforcement around it, is welded with grounding screw on the inner surface, simultaneously at the equal outdoor molding powder of plastic-blasting in each surface of cover plate 4.A side of cover plate 4 flexibly connects by hinge 5 and shell 1, and cover plate 4 is turned down to shell 1, can closure 1, make that shell and cover plate 4 are common to form an airtight casing.
The edge of described cover plate 4 also is provided with waterproof adhesive tape 6, is used for water-tight.
The inner surface of described cover plate 4 also is provided with pressing plate 7, and is provided with sealing gasket 8 between pressing plate 7 and cover plate 4 inner surfaces, and described sealing gasket 8 is made by heat barrier foam.Sealing gasket 8 can prevent and extraneous heat conduction, also can play the effect of water-tight.Pressing plate 7 is used for fixing sealing gasket 8.
The outer surface of described shell 1 is provided with at least one mounting panel 9.The outdoor molding powder of all mounting panel 9 surface plastic sprayings is used for whole casing 1 is fixedly mounted on the position of needs, can make different parts according to the actual requirements.
Also be respectively equipped with water joint 11 on described shell 1 and the inner casing 2.Water joint 11 is passages that External cable enters casing, also can play isolated box house simultaneously and contact with extraneous, plays the effect of water-tight.
The described plate 3 that is connected and fixed is made its surface sand-blasting anodic oxidation by an aluminium alloy by the earlier oblique respectively crooked down edge direction bending parallel with bonding jumper again in two ends.
