Description
Technical field
The utility model relates to the visual navaid light fixture in a kind of airport, is mainly arranged on the flight place on airport, provides visual navaid reference by the light sending different colours to pilot when taking off and land, and belongs to the visual navigational lighting aid technical field in airport.
Background technology
At present, voyage aid of the airport fitting structure is primarily of lamp body and lamp cylinder composition, and lamp body and lamp cylinder can integrally be installed also can partial installation, and lamp cylinder is arranged in cement concrete seat, lays isolating transformer and the connector with cable in lamp cylinder.
But this aid-to-navigation light lamps structure exists certain problem: one is that light fixture is bulky, too heavy, installation difficulty is large; Two is that lamp cylinder sealing difficulty is large, easily intakes, easily causes isolating transformer and joint to be immersed in water, reduce insulating properties, form short circuit; Three is that used fixed part and glass lamp shade contact area are too little, and pressure is too large, and glass lamp shade is fragile; Four is large with light fixture lamp cylinder cap separating difficulty after easy broken rod fractures, and is not easy to dismounting.
Therefore, need a kind of novel voyage aid of the airport light fixture of development badly, overcome above-mentioned drawback.
Summary of the invention
For above-mentioned existing technical problem, the utility model provides a kind of and installs simple constructability, and the visual navaid light fixture in airport that isolating transformer water resistance is good,
The utility model for achieving the above object, is achieved through the following technical solutions: the visual navaid light fixture in a kind of airport, connects to form from top to bottom successively primarily of glass lamp shade, protective cover, easy broken rod and lamp socket; Described lamp socket is the taper shape of a hollow, is fixed on screw rod pre-buried on concrete lamp socket bottom it; Described protective cover is the water-drop-shaped of hollow, is docked and forms, and accommodate isolating transformer and plug between upper and lower protective cover by upper protective cover and lower protective cover; Described isolating transformer profile is the drops identical with protective cover internal cavities shape; water droplet roundlet portion top surface is provided with the plug hole assigning outgoing line plug; water droplet great circle portion top surface is the step-like of the groove being provided with placing idle plug and cable, and water droplet great circle portion bottom surface is provided with inlet wire.This light fixture for citation form, first, totally eliminates the lamp cylinder that volume is larger with the omnibearing luminous light fixture in airport, improves former light fixture volume both bulk, the shortcoming of difficult installation; Secondly; isolating transformer profile in former lamp cylinder is slightly done to change; and between glass lamp shade and easy broken rod top, set up the protective cover of water-drop-shaped; replace the lamp cylinder laying isolating transformer; isolating transformer is all protected, and protective cover inner chamber designs according to isolating transformer profile.Moreover isolating transformer is placed on certain height, is conducive to waterproof, does not do encapsulation process bottom light fixture at needs, this light fixture reduces the difficulty of installation and maintenance, and decreases the impact of water on light fixture to a great extent.
Further, described upper protective cover end face is provided with waterproof boss, can prevent rainwater from entering glass lamp shade, avoid the damage that rainwater causes electric light source and cable with glass lamp shade after being connected.Further, the junction of glass lamp shade and upper protective cover is also placed with rubber washer, and pushes down fixing by annular clinching part.The contact area of rubber washer and these two fixed parts of annular clinching and glass lamp shade increases, and reduces the pressure of fixed part to glass lamp shade, is so just not easy to occur that fixed part damages the phenomenon of glass lamp shade by pressure.And, the effect of seal glass lampshade is also played in rubber washer and annular clinching, rainwater flows into after rubber washer from glass lamp shade and can continue to flow out, and can not stay in glass lamp shade, so lessens the possibility that the parts in glass lamp shade damage because of rainwater.
Further; be provided with the underpass hole that wears isolating transformer cable bottom described lower protective cover, and bottom surface is provided with a protective cover sleeve concentric with underpass hole, in order to connect easy broken rod upper end; the connection of protective cover and easy broken rod is simplified, facilitates and install and maintenance.And underpass bore dia is less than the diameter of lower protective cover sleeve, be convenient to when installing, determine that easy broken rod inserts the length of lower protective cover tube-in-tube structure.
Further, the bound fraction of described upper and lower protective cover is the faulting of slab ends structure coordinated, and can ensure that rainwater can not enter protective cover inside, avoid rainwater to cause damage to isolating transformer.And upper protective cover side is provided with the screw can fixing upper and lower protective cover, fixes upper and lower protective cover by screw-driving, make both easily dismountings, convenient installation, maintenance.
Further, described easy broken rod is the long tubular of hollow, and its lower end connects one with the sleeve of screw, for plug-in mounting lamp socket top; Cartridges sides is provided with sleeve screw, and for fixed lamp-socket top, and lamp socket top is also designed to the barrel shaped structure of the protrusion be connected with easy broken rod lower sleeve, and be convenient to both peaces and tear open, convenient for maintaining changes part.
Further, described plug comprises two column type copper posts and two plug bonds, and plug inserts in the jack of isolating transformer, and plug bond is connected to lamp socket by the upper through wires hole on upper protective cover.Plug position is also brought up in the protective cover of the isolating transformer on more than ground, decreases rainwater and seepage in underground to the impact at metallic conduction position.
To sum up, the utility model light fixture decreases the impact of water on light fixture to a great extent, reduce maintenance difficulties, improve the maintainability of light fixture and the reliability of airfield light guarantee, reach and simple, easy to maintenance, dependable performance, raising flight support ability object is installed.
