Description

Technical Field

[0001] The present invention relates to a device for guiding the cleaning state objectively without the driver of a construction vehicle getting out of the driver's seat when using a vehicle mud removal cleaning device. Specifically, it relates to a vehicle mud removal cleaning guide device that efficiently guides the cleaning state of a vehicle mud removal cleaning device that is designed to wash away dirt such as mud adhering to each tire, the bottom surface, or the side surface of the vehicle body of construction vehicles such as dump trucks in a short period of time, to the driver of the construction vehicle.

Background Art

[0002] Conventionally, at construction sites such as civil engineering and construction sites, when a construction vehicle exits the site, if foreign substances such as mud and small stones adhering to the tires of the vehicle and the vicinity thereof (hereinafter simply referred to as "mud") are left as they are, the mud will fall from the exited vehicle, contaminating the surrounding environment of the site. Therefore, at the site, the tires are cleaned at the time of exit to prevent the mud adhering to the vehicle from being carried out of the site.

[0003] Conventionally, as a method of removing mud adhering to a vehicle, there is a method of washing away the dirty tires using a high-pressure washer. However, when using a high-pressure washer, a power source such as a power supply or an engine is required, and personnel to handle the high-pressure washer are also required. At this time, if the driver of the construction vehicle himself / herself becomes the person handling the high-pressure washer, he / she has to get out of the driver's seat and work each time when exiting the site, which is unavoidably troublesome.

[0004] In addition, in the case of a large vehicle such as a construction vehicle, since the driver's seat is at a high position, getting on and off is very difficult, and an increase in the number of times of getting on and off may induce falling or jumping off, thereby increasing the risk of injury. Moreover, in the case of rain, since the soles of the shoes and the steps are wet, the risk of slipping and getting injured due to the rain further increases.

[0005] On the other hand, a conventional method involves creating a puddle near the exit of the site for construction vehicles to pass through, allowing the tires to enter the water and wash away the dirt. This method does not require electricity and allows for convenient handling of the situation without requiring the driver of the construction vehicle to get in and out each time. However, there is a risk that it may not be able to adequately remove mud that has gotten into the tire grooves and is firmly attached, or mud that has adhered to the bottom or sides of the vehicle.

[0006] Therefore, a vehicle mud-removal and cleaning device has been proposed that uses the self-propelled rotational force of a construction vehicle to rotate a pump, and utilizes the pressure of a cleaning medium such as water sprayed from nozzles positioned to hit each tire or the bottom or side of the vehicle body to quickly wash away mud adhering to the tires, etc. (see, for example, Patent Documents 1 and 2). This vehicle mud-removing and washing device allows for thorough removal of heavily adhering mud and dirt from tires and other parts without requiring electricity, and also eliminates the need for construction vehicle drivers to repeatedly get in and out of the vehicle to clean the tires and other parts.

[0007] However, conventionally, when mechanically removing mud using a vehicle mud-removing washing device, an appropriate vehicle speed and washing time are required during the dry run, depending on the condition of the mud. In other words, if the speed is too high or uneven, 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 low or if the machine stops midway, there is also a risk that the mud adhering to the tires cannot be sufficiently removed within a certain time.

[0008] While it is sometimes possible to station supervisors to monitor the cleaning process, this is difficult in areas with labor shortages, and drivers are forced to make their own judgments regarding vehicle speed and cleaning time. Therefore, even when using a vehicle mud-removal washing device, the driver of a construction vehicle is required to get out of the driver's seat to check the washing status. [Prior art documents] [Patent Documents]

[0009] [Patent Document 1] Patent No. 6629104 [Patent Document 2] Patent No. 6639957 [Overview of the project] [Problems that the invention aims to solve]

[0010] The present invention was developed in view of the above-mentioned conventional circumstances, and aims to provide a device that guides the driver of a construction vehicle so that they can objectively confirm the cleaning status without having to get out of the driver's seat when using a vehicle mud-removal cleaning device. [Means for solving the problem]

[0011] To achieve the above objective, a first aspect of the present invention is a vehicle mud-removal washing guide device that guides the driver of a construction vehicle about the washing state of a vehicle mud-removal washing device, which uses the pressure of a washing medium ejected from nozzles installed so as to strike the underside and sides of the construction vehicle to wash off mud adhering to the construction vehicle by running the construction vehicle empty on a group of rollers provided on a frame on which the front and rear tires of the construction vehicle are respectively placed, thereby rotating a pump, and washing off mud adhering to the construction vehicle, comprising a speed measuring means for measuring the speed of the construction vehicle running empty on the group of rollers, and a notification means for guiding the driver about the washing state of the construction vehicle based on the measured speed.

[0012] In other words, the vehicle mud-removal and washing guide device of the present invention rotates the tires of a construction vehicle on a group of rollers mounted on the frame of the vehicle mud-removal and washing device, and measures the vehicle speed at that time. Based on the outer diameter of the tires of the construction vehicle and the number of tire rotations calculated from the vehicle speed, the device determines the time when the washing is complete, in which mud and soil adhering to the tires and the underside and sides of the vehicle will be washed off, and guides the driver of the construction vehicle with the washing status of the construction vehicle.

[0013] In the above-described vehicle mud-removal washing guide device, the speed measuring means may be a rotation sensor that detects the rotation speed of the roller. Furthermore, it is preferable that the rotation sensor be an alternating magnetic field sensor.

[0014] In the vehicle mud-removal washing guide device, it is preferable that the notification means is a display device that outputs the washing status in a manner that can be visually recognized. In this case, the display device may include a light-emitting region and output the cleaning state by changing the light-emitting pattern in the light-emitting region. Furthermore, the light-emitting region is composed of LED units, and the light-emitting pattern in the light-emitting region is changed by at least one of the following: turning on, turning off, blinking, changing the light-emitting color, and changing the brightness of the LED units.

[0015] The aforementioned light-emitting region may be configured to output the cleaning status using a bar graph meter, the rate at which light is emitted changes in a bar-like pattern. The bar graph meter should preferably change the color of the light it emits depending on the quality of the cleaning. Furthermore, in the above-mentioned vehicle mud-removal washing guide device, it is desirable that the display device outputs the washing status based on the optimal vehicle speed and washing time.

[0016] In the above-described vehicle mud-removal and washing guide device, it is desirable that the display device be installed in a position where it can be seen from the driver's seat of the construction vehicle. In addition, in the above-described vehicle mud removal cleaning guide device, it is desirable that the display device includes a shield-shaped light-shielding frame around the display area.

[0017] In the above-described vehicle mud removal cleaning guide device, it is desirable that the notification means can guide the completion of cleaning together with the cleaning state. In addition, in the above-described vehicle mud removal cleaning guide device, the notification means may be a sounding device that outputs the cleaning state in a manner that can be recognized aurally.

[0018] Furthermore, in the above-described vehicle mud removal cleaning guide device, it is desirable that a renewable energy power generation device for supplying power to the notification means be provided. At this time, it is desirable that the renewable energy power generation device be a solar power generation device that generates electricity using sunlight.

Effects of the Invention

[0019] According to the present invention, since guidance for objectively confirming the cleaning state of a construction vehicle is provided based on an appropriate vehicle speed and cleaning time, efficient removal of mud can be achieved using the vehicle mud removal cleaning device, while reducing the burden on the on-site manager and reducing the manpower of monitors and the like who perform cleaning confirmation work. Therefore, it is possible to provide a device that guides so that the cleaning state can be objectively confirmed without the driver of the construction vehicle having to get out of the driver's seat when using the vehicle mud removal cleaning device.

[0021] <First Embodiment> Hereinafter, an example of an embodiment of the vehicle mud-removal and washing guide device according to the present invention will be described with reference to the drawings. The vehicle mud-removal and washing guide device according to the present invention (hereinafter simply referred to as the "guide device") is used in conjunction with a vehicle mud-removal and washing device (hereinafter simply referred to as the "washing device"), and is designed to inform the driver of the status of the washing of tires, etc., by the washing device. In other words, the present invention enables the driver of a construction vehicle such as a dump truck (hereinafter simply referred to as the "vehicle") to objectively check the washing status of tires, etc., without having to get in and out of the driver's seat each time.

[0022] The embodiments described below are preferred examples of the present invention and are subject to various technical limitations. However, the scope of the present invention is not limited to these forms unless otherwise specified in the following description.

[0023] As shown in Figure 1, the guide device 10 in this embodiment is installed near the cleaning device 30 and comprises at least a speed measuring 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 without moving on a group of rollers mounted on the frame of the washing device 30, and is installed on the rotation axis (shaft) of any one of the rollers in the group of rollers of the washing device 30. Such a speed measuring unit 1 can be, for example, a rotation sensor that detects the rotation speed of a roller. In other words, by detecting the rotational speed of the rollers, which are rotated using the power of a vehicle running idle on a group of rollers, the vehicle's speed can be calculated from that rotational speed and the size (outer diameter) of the vehicle's tires.

[0025] Such a rotation sensor could be, for example, an alternating magnetic field sensor 1 capable of distinguishing between the south pole and the north pole. The alternating magnetic field sensor 1 is designed to calculate the speed of a construction vehicle by attaching a magnet that alternately generates S-pole and N-pole magnetic fields to the rotation axis of a roller, detecting the switching between the S-pole and N-pole magnetic fields, and measuring the time between the changing pulse signals. In other words, the alternating magnetic field sensor 1 outputs a Low digital signal when the magnet switches from the North pole to the South pole, and outputs a High digital signal when the magnet switches from the South pole to the North pole.

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

[0027] The cleaning device 30 will now be described. As mentioned above, the cleaning device 30 is a device that quickly washes off mud and dirt adhering to the tires of a vehicle, as well as to the bottom and sides of the vehicle body and other areas near the tires, and can be the same as those disclosed in the prior art publications No. 6629104 and No. 6639957, which were cited as examples. Therefore, a detailed explanation of the above-mentioned cleaning device 30 will be left to the disclosure in the aforementioned patent publication, and a brief explanation will be given here.

[0028] As shown in Figures 7 and 8, the washing device 30 includes a frame body 31 on which the vehicle C travels for mud removal and washing. This frame body 31 is constructed as a frame in pairs of left and right sections using metal materials such as steel, and includes an entrance side slope 32, a rear wheel frame 33, a central slope 34, a front wheel frame 35, and an exit side slope 36.

[0029] The entrance-side ramp 32 is positioned to slope upward from the ground towards the rear wheel base 33, and is the area from which the vehicle C first drives before mud removal and washing. It has a convex surface on its upper side and is composed of a pair of ramps on the left and right sides.

[0030] The rear wheel support 33 is an area for cleaning mud off the rear wheels of the vehicle C, and is equipped with a group of rollers on which the rear wheels of the vehicle C, such as double tires, are placed, and is composed of a pair of left and right supports. In other words, the rear wheel frame 33 has pairs of rollers arranged along an axis perpendicular to the direction of travel of the vehicle C, and two sets of roller groups are provided along the direction of travel of the vehicle C. Specifically, for example, there is a rear-wheel drive roller group consisting of two rollers 331 and 332 corresponding to the rear tires of the rear wheels and two rollers 333 and 334 corresponding to the front tires of the rear wheels, with a total of eight rollers in each of the left and right rear-wheel drive roller groups.

[0031] The central slope 34 is a horizontally positioned area extending from the rear wheel base 33 to the front wheel base 35, and, like the entrance-side slope 32, has a convex surface on its upper side and is composed of a pair of left and right sections.

[0032] The front wheel support 35 has an area for cleaning mud off the front wheels of the vehicle C, and is equipped with a group of rollers on which the front wheels of the vehicle C, such as single tires, are placed, and is composed of a pair of left and right supports. In other words, the front wheel base 35, like the rear wheel base 33, is equipped with a group of rollers, each consisting of two rollers arranged in a direction perpendicular to the direction of travel of the vehicle C. Specifically, for example, it is equipped with a front-wheel drive roller group consisting of two rollers 351 and 352 corresponding to the front tires on each side, for a total of four rollers in the front-wheel drive roller group.

[0033] The exit-side slope 36 is positioned to slope downward from the front wheel base 35 towards the ground, and is the area through which the vehicle C, after mud removal and washing, finally exits. Similar to the entrance-side slope 32, it has a convex surface on its upper side and is composed of a pair of left and right slopes.

[0034] The manner in which the vehicle C is cleaned of mud using the cleaning device 30 configured in this way can be seen in Figure 9. First, as shown in Figure 9(a), vehicle C slowly moves from the entrance-side ramp 32 onto the frame body 1. Next, as shown in Figure 9(b), vehicle C moves until the front wheels are on the front wheel support 35 and the rear wheels are on the rear wheel support 33, and then stops. Then, the driver of vehicle C, for example, puts the gear into second gear and accelerates to a speed of about 20 km / h, and idles for about 10 seconds. As a result, the rotation of the rotary-driven rear wheels causes the first set of rollers from the entrance-side slope 32 to act as the driving axis, and the rotational interlocking mechanism causes the other rear wheels and the front wheels of vehicle C to rotate simultaneously.

[0035] At the same time, the pump is activated in conjunction with the rotation of the rear wheels, and water supplied from the tank as a cleaning medium is sprayed onto the bottom of each tire of vehicle C, washing away the mud and dirt adhering to the bottom of the tires. Simultaneously, water as a cleaning medium is also sprayed onto the sides of the vehicle body and the sides of the tires, washing away the mud and dirt adhering to these parts. Afterward, the driver of vehicle C shifts the gear back to neutral, bringing the tires to a complete stop. The pump also stops automatically when the tires come to a complete stop.

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

[0037] In this embodiment, the alternating magnetic field sensor 1 of the guide device 10 is attached, for example, to the rotation axis (shaft) of the roller 352 located in front of the vehicle C in the direction of travel, in the right-side roller group provided on the front wheel base 35 of the washing device 30, as shown in Figures 7 and 8. Specifically, magnets 11 are attached to two opposing positions in the radial direction of the rotation axis, and the positions of these 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 so that they can objectively check the cleaning status of the tires, etc., without having to get in and out of the driver's seat each time during the tire cleaning process shown in Figure 9(b).

[0039] Furthermore, the notification unit 2 is a device that provides information on the cleaning status of tires, etc., based on the speed calculated from the rotation speed of the roller measured by the alternating magnetic field sensor 1. This notification unit 2 can, for example, be a display device that outputs the cleaning status in a way that can be visually recognized. By providing visual information on the cleaning status using a display device, the cleaning status can be efficiently grasped at a glance.

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

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

[0042] As shown in Figure 2, the LED display board 2 of this embodiment includes a display unit 20, a control unit (display control microcontroller) 21 that controls the light emission pattern in the light emission area, and a first LED module 22 that indicates the cleaning status and a second LED module 23 that indicates the completion of cleaning, with multiple light-emitting diodes (LEDs) mounted on the substrate. In the LED display board 2, the light-emitting parts of the first LED module 22 and the second LED module 23 are provided on the display unit 20 so that they are exposed.

[0043] The first LED module 22 outputs the cleaning status using a bar graph meter, in which the proportion (degree) of light emission in the light-emitting area changes in a bar shape. In other words, the bar graph meter shows that as the cleaning progresses, the proportion of light emitted in the light-emitting area changes (increases) in a bar-like pattern. By displaying the cleaning status using a bar graph meter in this way, the cleaning status can be efficiently grasped in detail at a glance by observing the sequential changes in the rate of light emission in the light-emitting region.

[0044] Furthermore, the display unit 20 has a cleaning time indicator 24 next to (to the left of) the first LED module 22, which indicates the cleaning (completion) status according to the position indicated by the illumination of the first LED module 22. The content of this cleaning time indicator 24 will differ depending on the set cleaning completion time. In Figure 2, the bar graph meter is set to an optimal cleaning time of 10 seconds. Therefore, the washing time display 24 has "Start" displayed 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 way, the first LED module 22 determines the optimal vehicle speed and optimal washing time for washing, and displays the washing status based on these. Therefore, the first LED module 22 identifies the washing time from the vehicle speed measured by the alternating magnetic field sensor 1 until the end of washing, and identifies the vehicle speed required to complete washing from the set washing time, thereby guiding the user to the optimal conditions for efficient washing based on the vehicle speed and washing time.

[0046] Furthermore, the second LED module 23 outputs the completion of cleaning by a ring-shaped mark in which the light-emitting area changes from an off state to an on state. In other words, the cleaning is complete when the bar graph meter (light-emitting area) of the first LED module 22 is fully illuminated, and the second LED module 23 provides supplementary and easy-to-understand guidance.

[0047] In Figure 2, the second LED module 23 indicates the completion of cleaning with a double circle mark featuring a small annular light-emitting section and a large annular light-emitting section. Therefore, the illumination of the double circle mark indicates that the cleaning process has been completed properly. Furthermore, the LEDs that constitute the light-emitting area in the LED display panel 2 can be of various shapes, such as bullet-shaped, surface-mount (SMD), and chip-on-board (COB), as well as LED bulbs and LED fluorescent lamps.

[0048] The light emission patterns of the LED display panel 2 can be shown, for example, in Figures 3 to 5. Figure 3 indicates that the vehicle is being properly cleaned for 5 seconds while meeting the specified speed conditions. Specifically, if the appropriate cleaning conditions are set to a vehicle speed of 20 km / h or more and a cleaning time of 10 seconds, the cleaning time count starts when the vehicle speed exceeds 20 km / h, the bar graph meter of the first LED module 22 rises, and half of the light-emitting area illuminates, indicating that the appropriate vehicle speed has been maintained for 5 seconds while cleaning is being performed.

[0049] Furthermore, Figure 4 indicates that the cleaning has been completed while meeting the predetermined speed conditions. Specifically, the vehicle is cleaned while maintaining an appropriate vehicle speed for an additional 5 seconds (a total of 10 seconds) from the state shown in Figure 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 cleaning is complete.

[0050] Furthermore, Figure 5 indicates that the predetermined speed conditions are not being met. Specifically, although the vehicle maintained an appropriate speed up to a certain point, it became too slow just before the washing was completed. As a result, the washing time was not counted, the bar graph meter on the first LED module 22 stopped rising, and the light color changed, indicating that the washing conditions were not appropriate.

[0051] Thus, the bar graph meter of the first LED module 22 changes only the color of the light emitted, without changing the proportion of the light-emitting area, depending on the quality of the cleaning. Therefore, by using changes in the color of the emitted light as a bar graph meter to display the cleaning status, it is possible to efficiently grasp the situation during cleaning, including whether the cleaning is good or bad, at a glance through the changes in the emitted light.

[0052] While the light-emitting area could be composed of, for example, incandescent bulbs or fluorescent lamps, which are less expensive than LEDs, LEDs are preferable because they offer improved visibility and reduced power consumption compared to incandescent bulbs and fluorescent lamps. Furthermore, using LEDs allows for the creation of various light-emitting patterns depending on the cleaning condition, and their much longer lifespan compared to incandescent bulbs and fluorescent lamps reduces the hassle of replacing bulbs, making them desirable. Moreover, since incandescent bulbs are being phased out, it is preferable to use LED bulbs or LED fluorescent lamps.

[0053] Such an LED display board 2 is connected to an alternating magnetic field sensor 1 and is mounted on a support column 12. Specifically, it is desirable that the LED display board 2 be installed at a position (height) that can be seen from the driver's seat of the vehicle. By making the LED display board 2 visible from the driver's seat in this way, the driver can easily and efficiently check the washing status on the spot without having to get out of the driver's seat to check the washing status.

[0054] Furthermore, the LED display panel 2 is equipped with a canopy-like light-shielding frame 25 around the display area. This light-shielding frame 25 blocks sunlight from shining on the display area, making the output cleaning status easier to see.

[0055] Furthermore, the solar panel 3 is a power generation facility that generates electricity using sunlight, which is a renewable energy source, and includes a storage battery 4 that stores (charges) the generated electricity, and a charge / discharge controller 5 that controls the charging and discharging operations of the storage battery 4. In other words, the guide device 10 is equipped with a photovoltaic power generation system consisting 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 photovoltaic power generation system. Such a solar panel 3 can be installed, for example, at the upper end of a support column 12 to which an LED display board 2 is attached, thereby facilitating the supply of power from the solar panel 3 to the LED display board 2.

[0056] Furthermore, while the guide device 10 may supply power to the LED display board 2 using commercial power, it can also be equipped with a solar power generation system using a solar panel 3 to accommodate a cleaning device 30 that does not require electricity. In other words, it has fewer restrictions on the installation location and can be used even in sites where power is unavailable.

[0057] In the guide device 10 of this embodiment, as shown in Figure 6, the power generated by the solar panel 3 is used to charge 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 microcontroller 21 that controls the LED module 22 incorporated into the LED display board 2. In other words, the LED display board 2 is electrically connected to the solar panel 3 (photovoltaic power generation device), and the LED module 22 is driven by the power supplied from the solar panel 3. Furthermore, the LED module 22's display content (light emission pattern) is controlled according to conditions set by the display control microcontroller 21 based on the vehicle speed measured by the alternating magnetic field sensor (Hall sensor) 1.

[0058] Furthermore, in the guide device 10 of this embodiment, a first auxiliary sign 6 and a second auxiliary sign 7 are attached to the support column 12. In Figure 1, the first auxiliary sign 6 displays the words "Wash Confirmation," along with the words "Speed ​​20km / h," which indicates the optimal vehicle speed set on the LED display board 2, and the words "Keep for 10 seconds," which indicates the optimal washing time. In other words, the LED display board 2 informs the driver that the appropriate washing conditions are set to a vehicle speed of 20 km / h or more and a washing time of 10 seconds. This allows the driver to understand how to use the guide device 10 (conditions).

[0059] Furthermore, in Figure 1, the second auxiliary sign 7 displays the words "Red light: Insufficient speed," "Blue light: Sufficient speed," and "Blue circle: Washing complete," which explain the guidance on the LED display board 2. In other words, the LED display board 2 indicates that the bar graph meter of the first LED module 22 lights up red when the speed is insufficient, the bar graph meter of the first LED module 22 lights up blue when the speed is sufficient, and the second LED module 23 lights up blue when washing is complete. This allows the driver to understand the guidance 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 guides the driver to the optimal vehicle speed and washing time, thereby allowing the driver to objectively understand the washing state in which mud and other debris adhering to the vehicle body is removed without having to get in and out of the driver's seat.

[0061] In this embodiment, the optimal vehicle speed was set to 20 km / h or higher and the washing time to 10 seconds, as an example. However, the optimal conditions can be appropriately set based on factors such as tire size (outer diameter), groove shape and number, and the condition of the mud at the construction site.

[0062] <Second Embodiment> Furthermore, in the present invention, the cleaning status, which involves removing mud and other debris adhering to the vehicle body, can be output by means other than a visually recognizable method. In other words, it differs from the first embodiment described above in that, instead of a display device such as the LED display board 2 as the notification unit, it is equipped with a sound-emitting device that outputs the cleaning status in a manner that can be recognized audibly.

[0063] In the other embodiments described below, the focus will be on the differences from the first embodiment described above. Therefore, components similar to those in the first embodiment will be given the same names, their descriptions will be omitted, and they will be considered the same unless otherwise specified.

[0064] Although not shown in the figures, the guide device in this embodiment is installed together with the cleaning device regardless of its installation location, as long as the sound is within audible range, and comprises at least a speed measuring unit (for example, an alternating magnetic field sensor), a sounding device as a notification unit, and a solar power generation device (solar panel).

[0065] The sound-emitting device can be an acoustic device or audio equipment that emits specific sound effects such as "beep, beep, beep...", voice guidance such as "increase your speed", or alarm sounds such as music, in an audibly recognizable manner. Alternatively, it may be a combination of specific sound effects, voice guidance, and alarm sounds.

[0066] Therefore, by using an acoustic device or equipment that provides auditory (sound) information about the cleaning status instead of the LED display board 2 in the first embodiment described above, the cleaning status can be efficiently and easily grasped even when attention is not focused on the notification unit (even when performing other tasks or looking away). Furthermore, by using the aforementioned sound device or audio equipment, the on-site personnel in charge of the cleaning equipment can easily confirm whether the cleaning process has been completed properly.

[0067] It should be noted that this embodiment does not exclude the use of a display device. Therefore, a display device may be used together with the sound-emitting device; for example, the cleaning status may be indicated by sound emitted by the sound-emitting device, and the completion of cleaning may be indicated by light emitted by the display device. Conversely, the cleaning status may be indicated by light emission using a display device, and the completion of cleaning may be indicated by sound emission using a sound-emitting device. In other words, in the first embodiment described above, the completion of cleaning was indicated by the emission of light using the second LED module 23, but the completion of cleaning could also be indicated by emitting a buzzer sound, alarm sound, siren, voice guidance, etc.

[0068] <Other Embodiments> In the first embodiment described above, the cleaning status was indicated using a bar graph meter on the LED display board 2 as an example. However, the present invention is not limited to this, and for example, the output may be provided by a countdown timer with changing numbers. By indicating the cleaning status using the changing numbers of the countdown, it is possible to not only confirm that cleaning is in progress but also to know the remaining time until cleaning is completed, allowing for an efficient and quick understanding of the situation at a glance.

[0069] Furthermore, while the first embodiment described above illustrates the use of a second LED module 23 to indicate the completion of cleaning as an example, the present invention is not limited to this. For example, the completion of cleaning may be indicated by a dynamically emitting light fixture, such as a rotating light. This changes the method of visual recognition, allowing the status to be grasped efficiently at a glance.

[0070] Furthermore, in the first embodiment described above, a solar panel (photovoltaic power generation device) 3 was explained as an example of a renewable energy power generation device. However, the present invention is not limited to this, and other examples include wind power generation devices, hydroelectric power generation devices, geothermal power generation devices, biomass power generation devices, etc. Therefore, it is desirable to appropriately select a renewable energy power generation device according to the installation location (environment) of the cleaning device.

[0071] Furthermore, in this invention, if a communication network such as the Internet is available, the notification unit may not use an LED display board (display device) 2 or a sounding device, but instead push notifications of the washing status and washing completion information to a mobile terminal such as a smartphone or tablet computer used by the driver. These push notifications may also be provided from the cloud. [Industrial applicability]

[0072] The vehicle mud-removal and washing guide device of the present invention is expected to be used in conjunction with a vehicle mud-removal and washing device that quickly washes off mud and soil adhering to the tires and other parts of construction vehicles. [Explanation of Symbols]
