Description

Lighting lamp cleaning device using a brush {omitted}

Lights such as tunnels and street lamps have a risk of safety accidents due to smoke or dust, so that the outer surface of the glass cover for protecting the light bulb becomes dirty and the illuminance is lowered.

In order to solve this problem, conventionally, there is a method of cleaning a lamp by lowering the lamp to the ground by connecting a line capable of directly moving up or down by using a ladder mounted on a vehicle or by transporting a string of light. Such a conventional method requires a lot of effort and time for cleaning, and also causes a lot of troubles in the flow of traffic.

In order to solve the above problems, the lamp cleaning apparatus using the brush of the present invention is equipped with a brush operated by a motor to be in close contact with the outer surface of the glass cover of the lamp, and operate the brush according to the set time of the timer Keep illuminance constant

In the cleaning device of a lighting lamp having a glass cover for bulb protection,

The present invention is a frame (1) formed with a rectangular through-hole in the same size as the glass cover in the center so that the light of the lamp is not disturbed, and

It is configured to be elastically in close contact with the outer surface of the glass cover of the lamp, and a fixed end (3) for fixing the power transmission linear member (2) such as belt or wire is formed at both ends and the side close to the motor (4) A brush (7) having protrusions (6) formed at left and right to operate switch 2 (5) at one end thereof;

The guide end is formed perpendicular to the longitudinal direction of the brush 7 so as to support the brush 7 when the brush 7 moves left and right in association with the fixed end 3 so that the fixed end 3 is in close contact with the groove. A guide 8 configured to slide in a fixed shape to the outer mold 1 and

A motor 4 fixedly mounted on the outer mold 1 and configured with a shaft wheel on the shaft so that the linear member 2 is wound to move the brush 7 from side to side;

A plurality of pulleys 9 installed at positions where the direction of movement of the linear member 2 of the outer mold 1 changes to maintain the movement of the linear member 2 and to smooth the movement thereof;

By changing the (+) and (-) poles of the DC current supplied to the motor 4 in conjunction with the converter 10, the rotation direction of the motor 4 is changed to change the movement direction of the brush 7 from left to right. Switch 1 (11) configured to switch from right to left,

A switch 2 (5) for stopping at both ends of the glass cover when the brush 7 stops according to the time setting of the timer 12;

Timer 12 for turning on and off the electricity supplied to the converter 10 according to the set time and on and off the current supplied to the DC power supply 13 to the contrary to the converter 10,

A conversion configured to change the rotational direction of the motor 4 by converting the alternating current into direct current and changing the positive and negative poles of electricity supplied to the motor 4 in conjunction with the switch 1 (11). Device 10,

DC power supply for supplying electricity to the motor (4) until the brush (7) stops at both ends in connection with the switch 2 (5) the current that is turned on and off opposite to the converter 10 in the timer (12) ( The invention relates to a lamp cleaning apparatus using a brush (7) characterized in that consisting of 13).

The switch 1 (11) is fixedly installed on the brush (7), the left and right flow is fixed by fixing the center of the rod-shaped pin 14 protruding both ends to the outside of the switch 1 (11) with a leaf spring (15) It is possible to intervene and form an electrical contact in the center of the pin 14, and the connection between the two contacts and the pin 14 formed in the left and right at intervals in the interior of the outer shape of the switch 1 (11) alternatively connected In this way, the flow of electricity through each connection can be configured in the opposite direction in association with the converter 10 so as to change the rotational direction of the motor 4 and the moving direction of the brush 7. The leaf spring 15 is fixed up and down in the center of the pin 14, and both ends of the protruding end of the pin 14 collides with the movement of the protruding plate 16, which is fixed to the outer frame according to the movement of the brush The pin 14 is configured to have a degree of elasticity that can flow left and right. The protrusion plate 16 is fixed to the same line as the switch 1 (11) on the left and right sides of the outer mold serves to flow the pin 14 of the switch 1 (11). In accordance with the connection of the switch 1 (11), the direction of the current supplied to the motor (4) is changed in conjunction with the converter 10, so that the rotation direction of the motor (4) is changed and the moving direction of the brush (7) linked to the left is left. To right or left to right.

The ratio of the moving distance of the shaft wheel and the linear member 2 can be adjusted by a method of constructing a plurality of gears or shaft wheels as necessary.

Switch 2 (5) is fixed to each one of the left and right center of the outer frame (1) so that the brush (7) stops at both ends of the glass cover, the coil spring (17) to maintain the on state when no external force is applied. When it interposes and hits the protrusion formed in the brush 7, it is comprised so that it may be in an off state according to a pushing force.

The timer 12 accepts external electricity and turns on and off the electricity supplied to the converter 10 and the electricity supplied to the DC power supply 13 according to the set time, but the converter 10 and the DC power supply 13 The on-off state of the electricity supplied to is always configured to be reversed.

Looking at the step of cleaning the lamp of the present invention step by step,

The timer 12 operates so that the current flowing to the converter 10 is turned on. The converter 10 converts alternating current into direct current so that the direct current is supplied to the motor 4 in association with the switch 1 (11). A first step in which the brush 7 is operated;

The brush 7 moves to the protruding plate 16 formed in the outer mold 1, and an impact is applied to the protruding pin 14 of the switch 1 11 so that the switch 1 11 has an impact force and a leaf spring. Step 2, in which the brush (7) moves in the opposite direction by changing the contact point by the action of (15) to change the positive and negative poles of the direct current supplied to the motor (4):

The brush 7 moves to the end of the outer mold 1 again and repeats the above two steps to reciprocate from side to side and clean the lamp;

According to the set time of the timer 12, the electricity supplied to the converter 10 is turned off and the electricity supplied to the DC power supply 13 is turned on so that the brush 7 switches off the switch 2 (5). 4 steps to move until the;

The switch 2 (5) collides with the protruding portion 6 of the brush 7 to be turned off, and is composed of five steps in which the brush 7 stops at the end of the glass cover.

In the first to third steps, since only the electric current flowing from the timer 12 to the converter 10 and the current flowing to the DC power supply 13 are off, the switch 1 (11) connected to the converter 10 is turned off. By the operation of the motor 4 is made, the switch 2 (5) does not have any action. In steps 4 and 5, since the electricity flowing from the timer 12 to the converter 10 is in an off state and only the current flowing in the DC power supply device 13 is on, the switch 1 11 does not have any action. The motor 4 is actuated by a switch 2 5 connected to the device.

The present invention may be applied to a manufacturing step of a lighting lamp to configure the outer mold 1 integrally with the outer shape of the lighting lamp, or may be applied to a conventionally made lighting lamp by manufacturing the outer mold 1 and binding.

By maintaining the illuminance of the lights installed in difficult places such as tunnel lights or street lights, it protects the driver's safety, facilitates the traffic flow and saves effort and time due to the cleaning of the tunnel lights.
