Abstract
The utility model relates to a dustproof device for illuminating lamps in tunnels, which is composed of an electric retractor, a crank slide bar mechanism, a restoring spring, a dustproof cover and sealing material, wherein the electric retractor and an illuminating lamp are connected in parallel. When the illuminating lamp is turned on, the power of the electric retractor is simultaneously switched on and the crank slide bar mechanism is used for pulling the dustproof cover to be opened. When the illuminating lamp is turned off, the power of the electric retractor is simultaneously switched off and the restoring spring is used for pulling and closing the dustproof cover. When the illuminating lamp does not work, the illuminating lamp is free from being polluted by dust and smoke. The utility model has the characteristics of electricity saving, simple structure, good seal and dustproof properties, etc., and is favorable for improving the illuminating effect.
Description
The utility model relates to a kind of tunnel illumination light fixture dustproof device that is used for.
Known tunnel illumination light fixture dust guard is to adopt permanent magnet that dust cap is held.In the time of need opening dust cap, act on push rod by electromagnet and back down it, make its suction that breaks away from permanent magnet, deadweight falls and opens by dust cap; When need close dust cap, by the motor-driven reduction gear,, draw dust cap that it is covered, and make the motor outage by one stroke switch control is spacing with rope by a rope sheave, and dust cap close up suction fully by permanent magnet.This dust guard can be controlled the Push And Release of dust cap on demand, but control mode is complicated, and required control element is many, and the fault that causes thus is also more, and the work of the work of motor and illuminating lamp is asynchronous, needs the powerup issue of otherwise address motor again.
The purpose of this utility model is the design tunnel illumination light fixture dust guard that a kind of structure is simpler, control is more convenient, fault rate is low.
The purpose of this utility model is achieved in that a tractizer is set in the light fixture side, this tractor work of also switching on simultaneously when illumination lamp ignition, its traction steel wire action is by the slide crank linkage, dust cap is opened, and houselights passes transparent glass to external exposure.When illuminating lamp is closed, the tractor outage, tractive force disappears, and by back-moving spring dust cap is retracted closure.
The utlity model has following advantage: 1) control mode is simple.Characteristics such as the tractor that this device adopts has the automatic blocking function, can work simultaneously with illuminating lamp, and it is long to have a stream time, and power consumption is little.Because the duty of tractor can be synchronous with the work of illuminating lamp, therefore simplified control mode greatly, reduced fault rate.The slide crank linkage is simple in structure, and reliable in action is easy to adjust, can be effectively the tractive force of tractizer be sent on the dust cap.Action was at the uniform velocity steady when dust cap was opened.Back-moving spring reasonable in design, its restoring force can retract cover plate effectively, and it is closely contacted with light fixture.2) dustproof effect is obvious, helps to improve the illuminating effect of illuminating lamp.Adopt encapsulant be glued at dust cap around, prevented the intrusion of flue dust effectively, to keep the cleaning of illuminating lamp, improve its illuminating effect.In addition, because dust cap adopts aluminum metallic material, its good reflection action also helps to improve illuminating effect.
Fig. 1 has described an embodiment of the present utility model.
As shown in Figure 1,, an electronic tractizer 9 is set in the light fixture side, when tractizer 9 energisings, makes it to open by crank 5, interlock slide bar 3 traction dust caps 7 by gripper shoe 6; When tractizer 9 outages, directly act on dust cap 7 by two back-moving springs 4 it is closed.The working power of tractizer 9 is in parallel with lighting lamp power, and synchronous working.The traction steel wire 10 of tractizer 9 is fixed in the groove of crank 5.The crank 5, the interlock slide bar 3 that are installed in tractizer 9 bottoms are connected with dust cap 7 sides by hinge seat 11.Two back-moving springs 4 are installed in the two ends of the pivot of dust cap 7 rotations, and spring 4 one ends make hook-shaped, the side of hooking dust cap 7.The draft travel that this dust guard is regulated interlock slide bar 3 by adjusting nut 1, thereby the opening degree of control dust cap 7.The edge on dust cap 7 planes is bonded at encapsulant 8 on the dust cap 7 with chemical glue.This lighting dust guard guarantees that by limiting bracket 2 movement parts do not collide with tunnel wall.
