Description

[Technical field]

[0001] The present invention relates to a device that guides the driver of a construction vehicle so that he or she can objectively check the cleaning status without having to get out of the driver's seat when using a vehicle mud removal and cleaning device. More specifically, the invention relates to a vehicle mud removal and cleaning guide device that efficiently guides the driver of a construction vehicle about the cleaning status of a vehicle mud removal and cleaning device that is designed to quickly wash away mud and other dirt that has adhered to the tires, bottom or sides of the body, of construction vehicles such as dump trucks, etc. [Background technology]

[0002] In the past, when construction vehicles left civil engineering or construction sites, if they left foreign objects such as mud, pebbles, etc. (hereinafter referred to simply as "mud") attached to the vehicle's tires or in the vicinity, the mud would fall from the exiting vehicle and pollute the environment around the site. For this reason, when leaving the site, tires and other parts are cleaned to prevent mud adhering to the vehicle from being carried away outside the site.

[0003] Conventionally, one method for removing mud from a vehicle is to wash off the dirty tires using a high-pressure washer. However, when using a high-pressure washer, a power source such as a power source or an engine is required, and personnel are also required to operate the high-pressure washer. In this case, if the driver of the construction vehicle were to operate the high-pressure washer himself, he would have to get off the driver's seat and operate the machine every time he left the site, which is troublesome.

[0004] In addition, in large vehicles such as construction vehicles, the driver's seat is located high up, making it difficult to get in and out of the vehicle, and increasing the number of times the driver gets in and out of the vehicle can lead to falls or jumps, which can result in injury. Moreover, in rainy weather, the soles of shoes and steps are wet, which further increases the risk of slipping and getting injured.

[0005] On the other hand, a conventional method is to create a puddle near the exit of the construction site for construction vehicles to pass through, and then have the tires plunge into the water to wash off the dirty tires. This method does not require electricity, and the driver of the construction vehicle does not need to get in and out of the vehicle each time, making it easy to deal with the situation. However, there is a risk that the mud that has penetrated into the tire grooves and adhered firmly to the bottom or sides of the vehicle body may not be removed sufficiently.

[0006] Therefore, a vehicle mud washing device has been proposed in which a pump is rotated by the self-propelled rotational force of the construction vehicle, and the pressure of a cleaning medium such as water sprayed from nozzles installed so as to hit each tire or the bottom or side of the vehicle body is used to quickly wash away mud adhering to tires, etc. (see, for example, Patent Documents 1 and 2). This vehicle mud washing device can thoroughly wash away mud that has strongly adhered to tires, etc., without requiring electricity, and enables the driver of the construction vehicle to deal with the task without having to get in and out of the vehicle each time to wash off dirt from the tires, etc.

[0007] However, in the past, when using a vehicle mud washing device to mechanically remove mud, appropriate vehicle speeds and washing times during idling are required depending on the state of the mud. That is, if the speed is too fast or there is an unevenness in the speed, there is a risk that the mud adhering to the tires cannot be sufficiently removed within a certain time. On the other hand, if the speed is too slow or the vehicle stops midway, there is also a risk that the mud adhering to the tires cannot be sufficiently removed within a certain time.

[0008] At this time, inspectors are sometimes assigned to check the cleaning progress, but in sites where there is a labor shortage, it is difficult to assign inspectors, so the driver handles the situation by determining the vehicle speed and cleaning time for himself. Therefore, even when a vehicle mud removal and washing device is used, the driver of the construction vehicle is forced to get out of the driver's seat to check the washing condition.

[Means for solving the problem]

[0011] In order to achieve the above-mentioned object, a first aspect of the present invention is a device that guides the driver of a construction vehicle about the cleaning status of a vehicle mud removal cleaning device that operates the construction vehicle idly on a group of rollers provided on a stand on which the front and rear tires of the construction vehicle are respectively placed, rotating a pump and using the pressure of the cleaning medium sprayed from nozzles installed so as to hit the underside and sides of the construction vehicle to wash off mud adhering to the construction vehicle, the vehicle mud removal cleaning guide device being characterized in that it comprises a speed measuring means for measuring the speed of the construction vehicle operating idly on the group of rollers, and an announcing means for notifying the driver of the cleaning status of the construction vehicle based on the measured speed.

[0012] In other words, the vehicle mud removal cleaning guide device of the present invention works by rotating the tires of a construction vehicle idly on a group of rollers mounted on the base of the vehicle mud removal cleaning device and measuring the vehicle speed at that time, and then determining the end time of cleaning when the mud adhering to the tires of the construction vehicle and the underside and sides of the vehicle will be washed away based on the outer diameter of the construction vehicle's tires and the number of tire rotations calculated from the vehicle speed, and providing this information to the driver of the construction vehicle as the cleaning status of the construction vehicle.

[0013] In the above vehicle mud washing guide device, the speed measuring means may be a rotation sensor which detects the number of rotations of the roller. The rotation sensor is preferably an alternating magnetic field sensor.

[0014] In the vehicle mud removal cleaning guide device, it is preferable that the notification means is a display device which outputs the cleaning state in a visually recognizable manner. In this case, the display device may include a light-emitting area, and the cleaning state may be output by a change in a light-emitting pattern in the light-emitting area. In addition, the light-emitting area may be configured with an LED unit, and the light-emitting pattern in the light-emitting area may be changed by at least one selected from turning on, turning off, blinking, changing the light color, and changing the brightness of the LED unit.

[0015] The light emitting area may preferably output the cleaning state using a bar graph meter in which the proportion of light emitted changes in a bar shape. The bar graph meter may be configured to emit light of a different color depending on the quality of the cleaning state. In the vehicle mud removal washing guide device, it is preferable that the display device outputs the washing state based on an optimum vehicle speed and washing time.

[0016] In the vehicle mud removal and cleaning guide device, it is desirable that the display device be installed in a position visible from the driver's seat of the construction vehicle. In the above vehicle mud removal washing guide device, it is preferable that the display device is provided with a canopy-shaped light-shielding frame around the periphery of the display area.

[0017] In the above vehicle mud removal cleaning guide device, it is preferable that the notification means can notify completion of cleaning together with the cleaning state. In the vehicle mud removal washing guide device, the notification means may be a sound generating device which outputs the washing state in an audible manner.

[0018] Furthermore, in the above vehicle mud removal washing guide device, it is preferable to further include a renewable energy power generation device that supplies power to the notification means. In this case, it is preferable that the renewable energy power generation device is a solar power generation device that generates power by utilizing sunlight. Effect of the Invention

[0019] According to this invention, guidance is provided to objectively check the cleaning status of construction vehicles based on appropriate vehicle speed and cleaning time, which enables efficient mud removal using a vehicle mud removal cleaning device, while also reducing the burden on site managers and reducing the manpower required for inspectors and other personnel performing cleaning confirmation work. Therefore, when the vehicle mud removal cleaning device is used, a device can be provided that guides the driver of the construction vehicle so that he or she can objectively check the cleaning condition without having to get out of the driver's seat.

[0021] First Embodiment DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a vehicle mud washing guide device according to the present invention will now be described with reference to the drawings. The vehicle mud removal and cleaning guide device (hereinafter simply referred to as the "guide device") according to the present invention is used together with a vehicle mud removal and cleaning device (hereinafter simply referred to as the "cleaning device") and is designed to guide the driver of the state in which tires, etc. are being cleaned in the cleaning device. In other words, the present invention allows the driver of a construction vehicle such as a dump truck (hereinafter simply referred to as the "vehicle") to objectively check the cleaning state of tires, etc., without having to get in and out of the driver's seat each time.

[0022] In addition, the embodiments described below are preferred specific examples of the present invention, and therefore various technical limitations are imposed thereon. However, the scope of the present invention is not limited to these embodiments unless otherwise specified in the following description.

[0023] As shown in FIG. 1, a guide device 10 in this embodiment is installed in the vicinity of a cleaning device 30, and includes at least a speed measurement unit 1, a notification unit 2, and a solar panel 3.

[0024] The speed measurement unit 1 is a device that measures the speed of a vehicle running idle on a group of rollers provided on a stand of the cleaning device 30, and is installed on the rotation axis (shaft) of one of the rollers in the group of rollers in the cleaning device 30. Such a speed measurement unit 1 can be, for example, a rotation sensor that detects the number of rotations of a roller. In other words, by detecting the number of rotations of the rollers rotated using the power of a vehicle idling on the group of rollers, the speed of the vehicle can be calculated from the number of rotations and the size (outer diameter) of the vehicle's tires.

[0025] Such a rotation sensor can be, for example, an alternating magnetic field sensor 1 capable of distinguishing between a south pole and a north pole. The alternating magnetic field sensor 1 is a device that attaches a magnet that generates alternating magnetic fields with south and north poles to the rotating shaft of a roller, detects the switching of the magnetic fields between the south and north poles, and measures the time between the changing pulse signals, thereby making it possible to calculate the speed of the construction vehicle. That is, the alternating magnetic field sensor 1 outputs a low digital signal when the magnet switches from a north pole to a south pole, and outputs a high digital signal when the magnet switches from a south pole to a north pole.

[0026] Therefore, the speed can be calculated based on the number of rotations per unit time of the magnet obtained from the detected signal. By using the alternating magnetic field sensor 1 as a rotation sensor, it is possible to reduce power consumption compared to other rotation sensors, such as a proximity sensor.

[0027] Here, we will explain the washing device 30. As described above, the washing device 30 is a device that quickly washes away mud adhering to vehicle tires and to the vicinity of the tires, such as the bottom and sides of the vehicle body, and may be the device disclosed in Japanese Patent No. 6629104 and Japanese Patent No. 6639957, which are exemplified as prior art. Therefore, a detailed description of the cleaning device 30 will be given in the above-mentioned patent publication, and only a brief description will be given here.

[0028] 7 and 8, the cleaning device 30 includes a frame body 31 on which a vehicle C travels for mud washing. The frame body 31 is made of a pair of left and right frames made of metal such as steel, and includes an entrance slope 32, a rear wheel stand 33, a central slope 34, a front wheel stand 35, and an exit slope 36.

[0029] The entrance slope 32 is arranged with an upward incline from the ground toward the rear wheel stand 33, and is the area where the vehicle C first runs out before mud cleaning, has a convex surface on the upper side, and is composed of a pair of slopes on the left and right.

[0030] The rear wheel stand 33 is an area for cleaning the rear wheels of the vehicle C, and is equipped with a group of rollers on which the rear wheels of the vehicle C, for example, dual tires, are placed, and is composed of a pair of rollers on the left and right. That is, in the rear wheel stand 33, two rollers are arranged in pairs with their axes perpendicular to the traveling direction of the vehicle C, and two roller groups are provided along the traveling direction of the vehicle C. Specifically, for example, the rear wheel drive roller groups each consisting of two rollers 331, 332 corresponding to the rear tires of the rear wheels and two rollers 333, 334 corresponding to the front tires of the rear wheels are provided on each side, making up a total of eight rollers in the rear wheel drive roller groups.

[0031] The central slope 34 is a horizontally arranged area spanning from the rear wheel stand 33 to the front wheel stand 35, and like the entrance slope 32, has a convex surface on the upper side and is composed of a pair of slopes, one on the left and one on the right.

[0032] The front wheel stand 35 is an area for cleaning the front wheel side of the vehicle C by removing mud, and is equipped with a group of rollers on which the front wheels of the vehicle C, for example, single tires, are placed, and is composed of a pair of rollers on the left and right. That is, the front wheel stand 35, like the rear wheel stand 33, is provided with roller groups each consisting of a pair of rollers arranged with their axes perpendicular to the traveling direction of the vehicle C. Specifically, for example, the front wheel drive roller groups each consisting of two rollers 351, 352 corresponding to the front wheel tires are provided on each side, making a total of four rollers.

[0033] The exit side slope 36 is arranged with a downward incline from the front wheel stand 35 toward the ground, and is the area where the vehicle C finally exits after being cleaned off. Like the entrance side slope 32, it has a convex surface on the upper side and is composed of a pair of slopes, one on the left and one on the right.

[0034] The manner in which mud is removed and washed from the vehicle C by the washing device 30 configured in this manner can be seen in FIG. First, as shown in FIG. 9(a), a vehicle C slowly advances from the entrance slope 32 onto the gantry body 1. Next, as shown in FIG. 9(b), the vehicle C moves until its front tires are placed on the front wheel stand 35 and its rear tires are placed on the rear wheel stand 33, and then stops. Then, the driver of vehicle C puts the gear into second gear, accelerates to about 20 km / h, and idles for about 10 seconds. Then, as the rear tires rotate, the first set of rollers from the entrance slope 32 becomes the driving shaft, and the rotation interlocking mechanism operates to idle the other tires on the rear side of vehicle C and the tires on the front side of vehicle C at the same time.

[0035] At this time, the pump is operated in conjunction with the rotation of the rear tires, and water as a cleaning medium supplied from the tank is sprayed toward the bottom of each tire of vehicle C, washing away mud adhering to the bottom of the tires. At the same time, water as a cleaning medium is also sprayed toward the sides of the vehicle body and the sides of the tires, washing away mud adhering to these parts. After that, the driver of vehicle C shifts the gear into neutral and brings the tires to a complete stop. When the tires come to a complete stop, the pump also stops.

[0036] Next, as shown in FIG. 9(c), the driver of vehicle C puts the vehicle into reverse and moves vehicle C backward by about 50 cm. Thereafter, as shown in FIG. 9(d), the driver of vehicle C puts the vehicle into first gear, for example, and slowly travels along the pedestal body 31, then travels forward from the exit slope 36, completing the series of operations.

[0037] 7 and 8, in this embodiment, the alternating magnetic field sensor 1 of the guide device 10 is attached to the rotation axis (shaft) of a roller 352 located at the front in the traveling direction of the vehicle C in a right-side roller group provided on the front wheel stand 35 of the cleaning device 30. Specifically, magnets 11 are attached to two opposing positions in the radial direction of the rotation axis, and the positions of the magnets 11 are detected by the alternating magnetic field sensor (Hall sensor) 1.

[0038] Therefore, the guide device 10 is used to guide the driver of vehicle C during the tire washing process shown in Figure 9(b) so that he or she can objectively check the washing condition of the tires, etc., without having to get in and out of the driver's seat each time.

[0039] The notification unit 2 is a device that notifies the cleaning status of tires, etc., based on the speed calculated from the number of rotations of the roller measured by the alternating magnetic field sensor 1. This notification unit 2 can be, for example, a display device that outputs the cleaning status in a visually recognizable manner. By visually notifying the cleaning status using the display device, the cleaning status can be efficiently grasped at a glance.

[0040] Such a display device can be, for example, a light-emitting device that has a light-emitting area and outputs the cleaning status by changing the light-emitting pattern in the light-emitting area. By displaying the cleaning status using the change in the light-emitting pattern in the light-emitting device, the cleaning status can be efficiently grasped in detail at a glance.

[0041] Furthermore, the light-emitting device may be, for example, an LED display board 2 whose light-emitting area is composed of one or more LED units, and which changes the light-emitting pattern in the light-emitting area by at least one selected from turning on, turning off, blinking, changing the light-emitting color, and changing the brightness of the LED units.

[0042] 2, the LED display board 2 of this embodiment includes a display unit 20, a control unit (display control microcomputer) 21 that controls the light emission pattern in the light emitting area, and a first LED module 22 that indicates the cleaning status and a second LED module 23 that indicates the completion of cleaning, each of which has a plurality of light emitting diodes (LEDs) mounted on a board. In the LED display board 2, the light emitting units of the first LED module 22 and the second LED module 23 are provided on the display unit 20 so as to be exposed.

[0043] The first LED module 22 outputs the cleaning state using a bar graph meter in which the proportion (degree) of light emitted in the light emitting area changes in a bar shape. That is, in the bar graph meter, the proportion of the light-emitting area that emits light changes (increases) in a bar shape as the cleaning state progresses. By displaying the cleaning status using a bar graph meter in this manner, the cleaning status can be grasped in detail and efficiently at a glance based on the change in the rate at which the light emitting areas sequentially emit light.

[0044] In addition, on the display unit 20, next to (to the left of) the first LED module 22, a cleaning time display 24 is provided to guide the cleaning (completion) state according to the position indicated by the light emitted by the first LED module 22. The display content of this cleaning time display 24 varies depending on the cleaning completion time to be set. In Figure 2, the bar graph meter shows the optimum cleaning time set to 10 seconds. Therefore, the cleaning time display 24 displays "START" at the bottom of the light emitting area, "5 seconds" in the middle of the light emitting area, and "10 seconds" at the top of the light emitting area.

[0045] In this manner, the first LED module 22 determines the optimum vehicle speed and optimum washing time for washing, and displays the washing state based on these. Therefore, the first LED module 22 determines the cleaning time required to complete cleaning from the vehicle speed measured by the alternating magnetic field sensor 1, and determines the vehicle speed required to complete cleaning from the set cleaning time, thereby providing guidance on the optimal conditions for efficient cleaning based on the vehicle speed and cleaning time.

[0046] The second LED module 23 outputs the completion of cleaning by means of an annular mark in which the light emitting area changes from an unlit state to a lit state. That is, the completion of cleaning can be determined when the bar graph meter (light emitting area) of the first LED module 22 is fully illuminated, and the second LED module 23 serves as an auxiliary means to provide easy-to-understand guidance.

[0047] In FIG. 2, the second LED module 23 notifies the user when cleaning is complete by using a double circle mark having a small annular light emitting portion and a large annular light emitting portion. Therefore, when the double circle mark is lit, it can be recognized that the cleaning has been properly completed. The LEDs constituting the light-emitting area of ​​the LED display board 2 may be of various shapes such as bullet type, surface mount type (SMD), chip on board (COB), etc., as well as LED light bulbs and LED fluorescent lamps.

[0048] The light emission patterns of the LED display panel 2 can be, for example, as shown in FIG. 3 to FIG. 3 indicates that the vehicle has been properly washed for 5 seconds while satisfying a predetermined speed condition. Specifically, if the proper washing conditions are a vehicle speed of 20km / h or more and a washing time of 10 seconds, counting the washing time starts when the vehicle speed exceeds 20km / h, the bar graph meter of the first LED module 22 rises, and half of the light-emitting area lights up, indicating that the vehicle has been properly washed for 5 seconds while maintaining the proper vehicle speed.

[0049] Fig. 4 also informs that the washing has been completed by satisfying a predetermined speed condition. Specifically, the washing is continued for another 5 seconds (total 10 seconds) while maintaining an appropriate vehicle speed from the state shown in Fig. 3, and the entire light-emitting area of ​​the bar graph meter of the first LED module 22 lights up and the double circle mark of the second LED module 23 lights up, indicating that the washing has been completed.

[0050] 5 also notifies the user that a certain speed condition is not met. Specifically, the vehicle maintains an appropriate vehicle speed until halfway through, but the speed becomes insufficient shortly before the completion of the wash, and the bar graph meter of the first LED module 22 stops rising without counting the wash time, and the light color is changed, indicating that the wash conditions are not appropriate.

[0051] In this way, the bar graph meter of the first LED module 22 changes only the color of light emitted depending on the quality of the cleaning state, without changing the proportion of the light-emitting area. Therefore, by displaying the cleaning status using changes in color emitted as a bar graph meter, the change in color emitted allows the user to efficiently grasp the cleaning situation in detail at a glance, including whether the cleaning status is good or bad.

[0052] The light-emitting area can be configured with, for example, an incandescent light bulb or a fluorescent light bulb, which are cheaper than LEDs, but LEDs are preferable because they can improve visibility and reduce power consumption compared to incandescent light bulbs and fluorescent lights. LEDs are also preferable because they can create various light-emitting patterns depending on the cleaning state and have a much longer life than incandescent light bulbs and fluorescent lights, reducing the effort required to replace the light bulbs. In addition, since incandescent light bulbs are being phased out, it is preferable to use LED light bulbs or LED fluorescent lights.

[0053] Such an LED display board 2 is connected to the alternating magnetic field sensor 1 and is attached to a support 12. Specifically, it is preferable that the LED display board 2 is installed at a position (height) that can be seen from the driver's seat of the vehicle. By being able to see the LED display board 2 from the driver's seat in this way, the driver can easily and efficiently grasp the cleaning status on the spot without getting off the driver's seat to check the cleaning status.

[0054] The LED display panel 2 is also provided with a visor-like light-shielding frame 25 around the periphery of the display area. This light-shielding frame 25 blocks sunlight shining onto the display area, making it easier to see the displayed cleaning status.

[0055] In addition, the solar panel 3 is a power generation facility that generates power by utilizing sunlight, which is a renewable energy source, and is equipped with a storage battery 4 that stores (charges) the generated power, and a charge / discharge controller 5 that controls the charging and discharging operation of the storage battery 4. That is, the guide device 10 is equipped with a solar power generation device composed of a solar panel 3, a storage battery 4, and a charge / discharge controller 5, and supplies power to the LED display board 2 using the solar power generation device. Such a solar cell panel 3 can be provided, for example, on the upper end of the support pole 12 to which the LED display board 2 is attached, thereby facilitating the supply of power from the solar cell panel 3 to the LED display board 2.

[0056] The guide device 10 may be one that supplies power to the LED display board 2 using a commercial power source, but by providing a solar power generation device using a solar panel 3, it can also be used with the cleaning device 30 that does not require power. In other words, there are few restrictions on where it can be installed, and it can be used even in locations where a power source cannot be used.

[0057] 6, in the guide device 10 of this embodiment, the power generated by the solar cell panel 3 is charged to the storage battery 4 under the control of the charge / discharge controller 5. The charge / discharge controller 5 also supplies the power stored in the storage battery 4 to the display control microcomputer 21 that controls the LED module 22 incorporated in the LED display board 2. That is, the LED display board 2 is electrically connected to a solar cell panel 3 (photovoltaic power generation device), and the LED module 22 is driven by power supplied from the solar cell panel 3. Also, the display content (light emission pattern) of the LED module 22 is controlled according to conditions set by a display control microcomputer 21 based on the vehicle speed measured by an alternating magnetic field sensor (Hall sensor) 1.

[0058] Further, in the guide device 10 of this embodiment, a first auxiliary marker 6 and a second auxiliary marker 7 are attached to the support pole 12. In FIG. 1, the first auxiliary sign 6 displays the words "Confirm cleaning", as well as the words "Speed ​​20km / h" indicating the optimum vehicle speed set on the LED display board 2, and the words "Keep for 10 seconds" indicating the optimum cleaning time. That is, the LED display board 2 informs the driver that the vehicle speed is set to 20 km / h or more and the washing time is set to 10 seconds as the appropriate washing conditions. This allows the driver to understand how to use the guide device 10 (conditions).

[0059] 1, the second auxiliary sign 7 displays the characters "Red light: insufficient speed", "Green light: good speed", and "Blue circle: cleaning completed" to explain the guidance on the LED display board 2. That is, on the LED display board 2, the bar graph meter of the first LED module 22 emits red light when the speed is insufficient, the bar graph meter of the first LED module 22 emits blue light when the speed is good, and the second LED module 23 emits blue light when cleaning is completed. This allows the driver to understand the guidance content on the LED display board 2.

[0060] As described above, when the washing device 30 is used, the guide device 10 of this embodiment measures the vehicle speed and provides guidance on the optimal vehicle speed and washing time, thereby making it possible to objectively grasp the washing condition for removing mud and other debris adhering to the vehicle body without the driver having to get in and out of the driver's seat.

[0061] In this embodiment, an example has been described in which the optimal vehicle speed is set to 20 km / h or more and the cleaning time is set to 10 seconds. However, the optimal conditions can be set appropriately based on the tire size (outer diameter), the shape and number of grooves, the condition of the mud at the construction site, etc.

[0062] Second Embodiment In addition, in the present invention, the cleaning state in which mud and the like adhering to the vehicle body is removed may be output by means other than a visually recognizable form. That is, it differs from the first embodiment described above in that, instead of a display device such as an LED display panel 2 as the notification section, it is provided with a sounding device that outputs the cleaning status in a manner that can be audibly recognized.

[0063] In the following description of the other embodiments, the differences from the first embodiment will be mainly described. Therefore, the same components as those in the first embodiment will be given the same names and the description thereof will be omitted, and they will be considered the same unless otherwise specified.

[0064] Although not shown in the figure, the guide device in this embodiment is installed together with the cleaning device regardless of the installation location as long as the sound can be heard, and is equipped with at least a speed measurement unit (e.g., an alternating magnetic field sensor), a sound-emitting device as an alarm unit, and a solar power generation device (solar cell panel).

[0065] The sound generating device may be an audio device or audio equipment that generates, as an auditory recognizable mode, a specific sound effect such as "beep, beep, beep...", a voice guidance such as "please speed up", an alarm sound such as music, etc. Also, a combination of specific sound effects, voice guidance, and alarm sounds may be used.

[0066] Therefore, by using an audio device or audio equipment that provides auditory (sound) information on the cleaning status instead of the LED display panel 2 in the first embodiment described above, the cleaning status can be grasped efficiently and easily even if the user is not paying attention to the alarm (performing other tasks or looking away). Furthermore, by using the audio device or audio equipment, the on-site staff in charge of the cleaning device can easily confirm whether the cleaning work has been completed properly.

[0067] In addition, this embodiment does not exclude the use of a display device in combination with the sounding device. Therefore, a display device may be used together with a sounding device, for example, the cleaning state may be notified by sounding using the sounding device, and the completion of cleaning may be notified by light emission using the display device. Conversely, the cleaning state may be notified by emitting light using a display device, and the completion of cleaning may be notified by emitting a sound using a sound generating device. That is, in the first embodiment described above, the second LED module 23 is used to emit light to indicate that cleaning is complete, but the completion of cleaning may also be indicated by emitting a buzzer sound, an alarm sound, a siren, audio guidance, or the like.

[0068] <Other embodiments> In the above-mentioned first embodiment, the cleaning status is indicated by using a bar graph meter on the LED display panel 2 as an example, but the present invention is not limited to this, and for example, it may be output by a countdown timer with changing numbers. In this way, by indicating the cleaning status using the change in the countdown numbers, not only can the user check that the cleaning is in progress, but the remaining time until the cleaning is completed can also be known, and the status can be efficiently grasped at a glance.

[0069] In the above-mentioned first embodiment, the second LED module 23 is used to inform the user that the cleaning is complete, but the present invention is not limited to this. For example, the cleaning completion may be notified by a lighting device that dynamically emits light, such as a rotating light. This changes the way of visual recognition, and the user can efficiently grasp the situation at a glance.

[0070] In addition, in the above-mentioned first embodiment, the solar cell panel (photovoltaic power generation device) 3 has been described as an example of the renewable energy power generation device, but the present invention is not limited to this, and examples include a wind power generation device, a hydroelectric power generation device, a geothermal power generation device, a biomass power generation device, etc. Therefore, it is desirable to appropriately select a renewable energy power generation device depending on the installation location (environment) of the cleaning device.

[0071] Furthermore, in the present invention, if the environment is one in which a communication network such as the Internet can be used, the notification unit may not use an LED display panel (display device) 2 or a sounding device, but may instead send push notifications of the cleaning status and cleaning completion information to a mobile device such as a smartphone or tablet computer used by the driver. This push notification may be provided from the cloud. [Industrial Applicability]
