Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for cleaning transparent plates arranged on both sides of a road.

[0002]

Conventionally, light-transmitting plates have been arranged on both sides of a highway or the like from the viewpoint of preventing obstruction of sunshine and a view, and the number of places where the light-shielding plate is used tends to increase. It is in.

Dust, exhaust gas, and the like flying up as the vehicle travels tends to adhere to the transparent plate, and if the transparent plate becomes cloudy, its function will deteriorate.

Therefore, it is necessary to clean the transparent plate, but since it is provided on both sides of the road over a long distance, it is difficult to clean the transparent plate manually. .

Therefore, an object of the present invention is to provide a light-transmitting plate cleaning device that can clean the light-transmitting plate easily and cleanly.

[0006]

In order to solve the above problems, the invention described in claim 1 is carried out by moving the transparent plate by moving it along the transparent plate. A light-transmitting plate cleaning device, comprising: a detergent spraying unit for spraying a detergent onto the light-transmitting plate; a fine vibrating unit for bringing a fine vibration member into contact with the light-transmitting plate on which the detergent adheres while giving a slight vibration; The water jetting means for jetting water to the transparent plate is a transparent plate cleaning device sequentially arranged from the front side in the moving direction.

According to this structure, the detergent is sprayed onto the light-transmitting plate by the detergent spraying means so that the dirt is lifted from the light-transmitting board, and the fine-vibration means slightly vibrates the fine-vibration member to allow the detergent to adhere. Contact the light plate to remove dirt. Then, the water jetting means jets water to wash away the detergent and dirt.

In this way, the light-transmitting plate cleaning device can be automatically cleaned by moving the light-transmitting plate cleaning device along the light-transmitting plate, and the workability is good.

By moving the microvibration member on the translucent plate while applying microvibration, a part of the dirt adhering to the translucent plate is removed by only the microvibration and is not removed by the microvibration. By wiping with a fine vibrating member, the dirt can be removed very effectively. By the way, in order to remove stains only by spraying detergent and water without providing a microvibration means, a considerably high pressure is required, and a large amount of detergent and water are required. In addition, the stains are removed better than when the stains are removed with a rotating brush, and the contact with the transparent plate is soft and the scratches are small.

Moreover, a small force is sufficient to move the microvibration member in the state where it is in contact with the transparent plate. A large force is required to move the microvibration member simply in contact with the translucent plate without applying microvibration.

According to a second aspect of the present invention, in addition to the structure described in the first aspect, when there is an obstacle in the middle of the light transmitting plate, the fine vibration member is separated from the light transmitting plate. It is characterized by the provision of avoidance means for avoiding obstacles.

According to this, since the microvibration member is brought into contact with the light transmitting plate to vibrate slightly, if an obstacle is present during movement, it will collide with it. By providing the avoidance means in this way, the microvibration member can be satisfactorily microvibrated without hitting an obstacle.

[0013]

Embodiments of the present invention will be described below.

1 to 6 show an example of an embodiment of the present invention.

First, the structure will be described. Reference numeral 1 in FIG.
With a boom that is mounted on truck 2 and driven three-dimensionally,
A transparent plate cleaning device 4 is arranged at the tip of the boom 1.

As shown in FIG. 6 and the like, the transparent plate cleaning device 4 is mounted on the tip of the boom 1 so that the support column 5 can be slid in the arrow direction by the drive of the motor 6.
A support plate 7 is arranged at the tip of the support column 5, and the support plate 7 is provided with a base plate 9 via a spring 8.
Are arranged.

As shown in FIGS. 1 and 4, etc., the base plate 9 has a detergent injection double-headed gun 10 as "detergent injection means" for injecting detergent onto the transparent plate 51 from the front side in the traveling direction.
A vibrating machine 12 as a "fine vibrating means" for contacting the sponge 11 as a "fine vibrating member" to the light transmissive plate 51 to which the detergent is attached while giving a slight vibration, and a "water jet" for injecting water to the translucent plate 51. Water injection nozzles 13 as "means" are sequentially arranged.

More specifically, the detergent injection double-headed gun 10 is
As shown in FIG. 4 and FIG. 5, a pair is provided in the upper and lower sides, and the gun 10 is divided by the divider 14 to supply the detergent. Then, the detergent is sprayed (1.7 L / min) from the nozzle 10a of the detergent spray double-headed gun 10 at a predetermined spray angle, and sprayed over the entire vertical width of the transparent plate 51 between the pair of fixed frames 50. It is supposed to be done. Also, on both sides of this detergent injection double-headed gun 10,
A pair of water jump prevention plates 15 are provided.

Further, as shown in FIGS. 4 and 6, the vibrators 12 generate slight vibrations, and three vibrators 12 are arranged vertically. The sponge 11 having an L-shaped cross section is arranged in the vibrator 12 in the vertical direction. The sponge 11 is in contact with the transparent plate 51, and the vertical length of the sponge 11 is set to be the same as the vertical length of the transparent plate 51 between the pair of fixed frames 50.

Further, as shown in FIG. 4, the water jet nozzles 13 are arranged at four positions vertically, and by spraying (8.0 L / min) from each nozzle 13, the entire vertical width of the transparent plate 51 is obtained. Water is sprayed over the entire area. A pair of water jump prevention plates 16 are arranged on both sides of the water jet nozzle 13.

When the sponge 11 is in contact with the transparent plate 51, the distance L between the water splash prevention plates 15 and 16 and the transparent plate 51 is more than the height H of the fixed frame 50 as an "obstacle". It is set high.

Further, as shown in FIG. 1, the base plate 9 is provided with a notice sensor 18, a backward movement start sensor 19 and a holding sensor 20 sequentially from the front side in the traveling direction.

The warning sensor 18 is a limit switch, which is turned on when the fixed frame 50 comes into contact with the limit switch, and turns on a yellow lamp (not shown) to notify the driver that the fixed frame 50 is approaching. ing.

The backward movement start sensor 19 is fixed to the fixed frame 50.
By contacting with, the motor 6 is driven by the signal from here and is retracted in the direction away from the transparent plate 51 by a distance according to the height H of the fixed frame 50.

These reverse start sensor 19 and holding sensor 2
When the fixed frame 50 is located in the middle of the transparent plate 51, the sponge 11 is separated from the transparent plate 51 by 0, and the fixed frame 5 is removed.
"Avoidance means" for avoiding from 0 is configured.

Next, the operation will be described.

To clean the transparent plate 51, the boom 1 of the truck 2 is operated to move the sponge 11 of the transparent plate cleaning device 4.
(For example, cellulose sponge (trade name))
And the track 2 is run along the translucent plate 51 in this state for cleaning. That is, first, a detergent injection double-headed gun 10 atomizes a detergent (for example, Soot Clean (trade name)) and sprays it onto the transparent plate 51. As a result, the fine mist of the detergent is evenly attached to the soiled surface, and the surface active agent causes the soil to be quickly lifted up. Then, in order to more effectively exert the force of the sprayed detergent, the vibrating machine 12 vibrates the sponge 11 to remove dirt from the transparent plate 51. Further, high-pressure water (maximum 160 kg / m ² ) is atomized from the water jet nozzle 13 into a transparent plate 51.
Spray cleaning on. As a result, fine mist-like water hits the cleaning surface at high pressure and at high speed, and the floating dirt is efficiently washed off. In this case, since the mist of water particles is small, the impact force is small and the cleaning surface of the transparent plate 51 is not damaged.

In this way, by moving the light-transmitting plate cleaning device 4 along the light-transmitting plate 51, the light-transmitting plate 51 can be automatically cleaned, and the workability is good.

Further, by moving the sponge 11 on the transparent plate 51 while applying a slight vibration, a part of the dirt adhering to the transparent plate 51 is removed only by the slight vibration and is not removed by the slight vibration. By wiping off the dirt with the sponge 11, the dirt can be removed very effectively. By the way, without removing the sponge 11 or the like, in order to remove the stains only by spraying the detergent and water, it is necessary to apply a considerably high pressure,
In addition, a large amount of detergent and water are required, and the stain removal is better than when the stain is removed with a rotating brush, and the light-transmitting plate 51 is softly contacted with less scratches.

Moreover, a small force is sufficient to move the sponge 11 in a state of being in contact with the translucent plate 51. A large force is required to move the sponge 11 simply in contact with the translucent plate 51 without giving a slight vibration.

A fixed frame 50 as an "obstacle" is provided along the vertical direction during the movement of the sponge 11, but the fixed frame 50 is avoided as follows.

That is, when the detergent spraying double-headed gun 10 passes over the fixed frame 50 and the advance notice sensor 18 detects the fixed frame 50, a yellow lamp is turned on by a signal from the sensor 18 and the driver Can recognize that the fixed frame 50 has approached. As a result, the driver slightly slows down the speed of the truck 2.

Next, when the fixed frame 50 is detected by the backward movement start sensor 19, the motor 6 is generated by the signal from the fixed frame 50.
In the direction in which the fixing frame 5 is driven away from the transparent plate 51.
It is retracted a distance L corresponding to a height H of zero.

Further, by the holding sensor 20, the fixed frame 5
When the side surface 50a (rising surface) of 0 is detected, the retracted state of the sponge 11 and the like is maintained for a predetermined time (time for the sponge 11 portion to pass through the fixed frame 50) from this time, and the time After 6 seconds, the motor 6 automatically
Is driven and the sponge 11 and the like are advanced to come into contact with the translucent plate 51.

Therefore, even if there is the fixed frame 50 on the way, this can be avoided and the transparent plate 51 can be cleaned well.

Further, since the water splash prevention plates 15 and 16 are disposed on both sides of the detergent spraying double-headed gun 10 and the water spraying nozzle 13, the detergent and water are less likely to be scattered and workability is improved. is there.

In the above embodiment, in order to avoid the fixed frame 50, the entire transparent plate cleaning device 4 is moved, but only the sponge 11 and the vibrator 12 are moved to move the fixed frame 50. It can be avoided. Further, although the sponge 11 is used as the “fine vibration member”, the invention is not limited to this, and it goes without saying that a brush-like member may be used.

[0038]

As described above, according to the invention described in claim 1, by moving the transparent plate cleaning device along the transparent plate, the transparent plate is automatically cleaned. It can be performed and the workability is good.

By vibrating the translucent plate while slightly vibrating the microvibration member, it is possible to remove dirt very effectively, and the soft translucent plate is softly touched and scratch-free. A small force may be used to move the microvibration member in a state of being in contact with the transparent plate.

According to the invention described in claim 2, in addition to the effect described in claim 1, since the microvibration member is brought into contact with the translucent plate to vibrate slightly, a frame or the like is moved during the movement. If there is an obstacle, it will collide with it. Therefore, if the avoiding means is provided as in the present invention, the microvibration member does not hit the obstacle, and the microvibration of the translucent plate is favorably performed. It has the practically useful effect of being able to.
