The high-pressure cleaning nozzles 21A and 21B, the tilting devices 22 of the high-pressure cleaning nozzles 21A and 21B, the lifting and lowering device 23, the swiveling device 24, and the high-pressure cleaning nozzle 28 are controlled by control lines as shown in FIG. Are respectively connected to the control device 31. The control device 31 includes a storage device 31m and also includes a reading device (not shown) that reads data from the outside.
The control device 31 includes an operation panel 32 that can be manually set, a distance sensor (may be a distance sensor using sound or laser light) 33, and an optical sensor that can detect the strongest light direction within a predetermined range. 34, a speed detection device 35 for detecting the traveling speed, a camera 1, a camera 2 capable of changing a projection direction that can capture an arbitrary direction, and an illuminance sensor (illuminance meter) 36 are connected. The control device 31 is connected to a monitor 37 for monitoring the images of the cameras 1 and 2.

The speed detection device 35 is configured to detect the traveling speed of the vehicle 1, and can actually use the speedometer of the vehicle 1.

  Thus, according to the tunnel high-speed traveling cleaning apparatus configured as described above, the tunnel can be cleaned while traveling at a high speed by acting as follows.

When trying to wash while moving at high speed the lighting fixtures 44 arranged along the length of the tunnel on the ceiling of a certain tunnel, for example, a specific tunnel on a highway (for example, the Tennozan tunnel on the Meishin Expressway) Data relating to the length of the tunnel and the arrangement position of the luminaire 44 in the tunnel is read out from the storage device 31m stored in advance as data. Based on this data, an angle from the high-pressure washing nozzles 21A, 21B on the vehicle 1 having a known size traveling on the road surface to the lighting fixture 44 is calculated in the control device 31, and based on the calculation result. The control device 31 sets the degree of expansion and contraction of the high-pressure washing nozzles 21A and 21B, the tilting device 22, the elevating device 23, the turning device 24, the discharge pressure of the high-pressure pump 25, and the like. In this case, as a condition of this operation, the vehicle 1, a position apart about 50cm from the lane marker 45 of the tunnel end (see FIG. 2) as to travel along the lane marker 45, it is calculated. The numerical value “50 cm” is not particularly limited, and may be 0 cm, 30 cm, or 60 cm. Further, although the reference lane marker 45, may be used as the reference curb portion is good or sidewalk reference to the side wall 40 of the tunnel Tn.

  Then, the control device 31 can change the direction of the light sensor 34, the camera 1 (or the camera 2), and the illuminance sensor 36 in the state where the light fixture 44 that is the cleaning object is directed. A control operation is performed on each of these actuators.

  In this case, the operator can set the setting condition of the control device 31 by operating the operation panel 32, and can change the setting value set by the control device 31.

Then, in this state, the driver, the vehicle 1 in a state a predetermined distance from the side walls 40 of the tunnel Tn, i.e., caused to travel along the lane marker 45 in a state where a distance of about 50cm from the lane marker 45 . At this time, the distance sensor 33 detects the distance from the side wall 40 of the tunnel Tn, and the data is sent to the control device 31. Controller 31 calculates an error on the distance when traveling away 50cm from pre lane marker 45 with data relating to the sensed distance, only the error amount, the high-pressure cleaning nozzles 21A, 21B stretch about the tilt device The correction is made so that the high-pressure washing nozzles 21A and 21B are in an optimum state by correcting the inclination angle of 22 and the degree of elevation of the elevation device 23 or the degree of revolution of the revolution device 23. The light sensor 34 also detects the direction of the target lighting fixture 44 by light and reflects it in the correction of the tilting device 22, the lifting device 23, the turning device 23, and the like.
The vehicle 1 is operated with the high-pressure pump 25 and the water heater 26 on the assumption that the vehicle 1 is traveling at a predetermined speed, for example, 50 km / h, which is the legal minimum traveling speed. May be different. For this reason, when the speed detection device 35 detects the traveling speed of the vehicle 1 and transmits detection data relating to the speed to the control device 31, the control device 31 detects the legal minimum traveling speed of 50 km / h. The rotational speed of the high-pressure pump 25 is controlled in accordance with the traveling speed, so that the amount of high-pressure water corresponding to the speed is supplied. At that time, the heating state of the water heater 26 is also controlled in accordance with the amount of the high-pressure hot water supplied. Specifically, when traveling at 55 km / h, the rotational speed of the high-pressure pump 25 is increased by that amount, and the degree of heating of the water heater 26 is increased. Further, the direction of the high-pressure washing nozzle 21 is changed as necessary.
Such correction is performed at appropriate intervals (for example, every 1/10 seconds) until the cleaning operation is completed. Therefore, the high-pressure washing nozzles 21A and 21B can always properly wash the target portion of the lighting fixture 44.
As for the cleaning status, an image captured by the camera 1 (or the camera 2) is displayed on the monitor 37, so that the operator can visually recognize the cleaning status. In such a case, it is desirable that the operator is not the driver of the vehicle 1 but an operator dedicated to the cleaning work. However, the driver may be an operator.
Further, the illuminance sensor 36 is configured to measure the illuminance of the illuminating device 44 after cleaning and confirm the cleaning effect. That is, it is possible to check whether or not the illuminance necessary for this tunnel is secured. Therefore, when the illuminance after cleaning is not in a desired state, the operator manually changes the rotation speed, the tilt angle, the elevation degree, the turning direction, etc. of the high-pressure pump 25 by operating the operation panel 32. Manual correction.

Further, when cleaning the lane marker 45 of the tunnel Tn, the actuates the high-pressure cleaning nozzle 28 may be cleaned by the case of cleaning as well as high-pressure hot water of the luminaire. In such a case, the given data and the detection data from the distance sensor 33 and the optical sensor 34 also contribute to the correction. Then, such a case, the camera 2 by that you set to mirror the rear of the vehicle 1, can be viewed on the same monitor 37 the cleaning status of the lane marker 45. In such a case, as described above, the plurality of high-pressure cleaning nozzles 28 are arranged at different angles with respect to the traveling direction so as to face from the front to the rear, so that the cleaning can be performed effectively. It has become.
In any of the above-described cleaning operations, high-pressure hot water containing bubbles is ejected from the high-pressure cleaning nozzles 21 and 28, so that the cavitation effect enables effective cleaning without using a detergent or the like. It becomes.

  Further, as the shape of the nozzle 48 of the nozzles of the high-pressure washing nozzles 21 and 28, a rectangular shape in front view as shown in FIG. By forming a throttle part (venturi part: a throttle of about 10% to 25% in the cross-sectional area of the passage, about 20% in this embodiment), high-pressure hot water that is wide and does not diffuse even when the distance is long. What can be jetted is used. As a result, the high-pressure hot water can be jetted / cleaned on the object to be cleaned more effectively.

By the way, the camera 1 and the camera 2 are arranged at appropriate positions on the high-pressure cleaning device 20, for example, the camera 1 is at the front end of the ceiling surface 20u of the high-pressure cleaning device 20, and the camera 2 is behind the ceiling surface 20u of the high-pressure cleaning device 20. It is preferable to arrange at the end. However, other positions may be used.
The distance sensor 33 is preferably disposed on the side surface of the high-pressure washing apparatus 20, the optical sensor 34 is preferably disposed on the ceiling surface 20u of the high-pressure washing apparatus 20, and the illuminance sensor 36 is disposed on the high-pressure washing apparatus 20. It is preferable to arrange at the rear end on the ceiling surface 20 u of the cleaning device 20. However, other positions may be used.

Incidentally, in this embodiment, has been described washing and cleaning and lane markers 45 of the luminaire 44 as performed separately, it is also possible to perform course simultaneously.

  Further, in this embodiment, the embodiment in which two high-pressure cleaning nozzles 21 are arranged has been described. Further, a cleaning apparatus in which three or more high-pressure cleaning nozzles 21 are arranged may be used.

  Further, the high-pressure washing nozzle 28 is not limited to the above-described example, and is not limited to other embodiments, for example, four, and may be two or one. It may be 4 or more.
