Best Mode for Carrying Out the Invention

[0014] Next, with reference to the attached drawings, embodiments of the present invention will be described to facilitate understanding of the present invention. In the drawings, parts not relevant to the description may be omitted from illustration.

[0015] As shown in FIGS. 1 and 2, a high-pressure cleaning drone 10 according to an embodiment of the present invention includes a fuselage 20, rod-shaped members 40a and 40b, and a nozzle 50, and can spray a cleaning liquid from the nozzle 50 to clean a wall surface (an example of a cleaning target) W in front. However, the cleaning target is not limited to the wall surface W.

[0016] The fuselage 20 has a fuselage main body 202, propellers 204, and skids 206. The fuselage main body 202 is equipped with a controller (not shown) for controlling the fuselage 20, a battery (not shown), and a camera (not shown) capable of photographing the front of the fuselage 20.

[0017] The propellers 204 are provided at the tips of arms 210 extending radially from the fuselage main body 202, and generate lift by being driven by motors 212 respectively. The number of propellers 204 may be any number. That is, the high-pressure cleaning drone 10 is not limited to a quadcopter.

[0018] The skids 206 are provided at the lower part of the fuselage main body 202 and are landing devices for supporting the fuselage 20 on the ground.

[0019] The rod-shaped members 40a and 40b are a pair of rod-shaped members that can contact the cleaning target, and in plan view, they extend in front of and behind the fuselage main body 202 with a space in the left-right direction. The reason why the rod-shaped members 40a and 40b extend not only forward but also backward is that a better balance of the fuselage 20 can be maintained compared to the case where they extend only forward. The rod-shaped members 40a and 40b are attached to the skid 206 and are each extendable and retractable in the longitudinal direction.

[0020] The rod-shaped members 40a and 40b each have spherical contact portions 402a and 402b at their front ends that can come into contact with the object to be cleaned. The contact parts 402a and 402b are made of, for example, resin and are colored in a highly visible color. This highly visible color is, for example, yellow, orange, or red.

[0021] The tips of the contact portions 402a and 402b (the tips of the rod-shaped members 40a and 40b) are located a distance L1 forward of the tip position A of the rotating propeller 204 when viewed from above. In other words, the position of the tips of the rod-shaped members 40a and 40b is forward of the rotation range of the propeller 204 when viewed from above. The position of the contact portions 402a and 402b (dimension L1) can be adjusted according to the length of the nozzle 50 in the front-rear direction by extending and retracting the rod-shaped members 40a and 40b.

[0022] Furthermore, the rod-shaped members 40a and 40b each have contact portions 404a and 404b at their rear ends that can come into contact with obstacles.

[0023] The nozzle 50 can spray the cleaning solution forward. The nozzle 50 is detachably attached to the tip of the cleaning fluid supply pipe 502 for supplying cleaning fluid, and its tip is located a distance L2 behind the tip position A of the rotating propeller 204 when viewed from above.

[0024] The cleaning fluid supply pipe 502 is fixed to the rod-shaped members 40a and 40b so as to pass through the center of gravity in the central part of the machine body 20 when viewed from above. The cleaning fluid supply pipe 502 is provided so as to extend forward of the machine body 202 between the rod-shaped members 40a and 40b when viewed from above, and the central axis of the cleaning fluid supply pipe 502 and the central axes of the rod-shaped members 40a and 40b are set to be at substantially the same height. However, the height positions of these central axes may differ in the vertical direction by, for example, within a range of 100 mm or less. A high-pressure hose 504 extending from the high-pressure washer unit 60, which is installed on the ground, is connected to the cleaning fluid supply pipe 502.

[0025] Next, we will explain the high-pressure cleaning operation (high-pressure cleaning method) using the high-pressure cleaning drone 10. High-pressure cleaning will be carried out according to the following steps S1 to S4.

[0026] (Step S1) First, the high-pressure cleaning drone 10 and the high-pressure cleaning machine body 60 are transported to a location close to the object to be cleaned. Subsequently, one end of the high-pressure hose 504 is connected to the cleaning fluid supply pipe 502, and the other end is connected to the high-pressure washer body 60. Furthermore, if necessary, the rod-shaped members 40a and 40b are extended or retracted in the longitudinal direction to adjust the front-to-back position (dimension L1) of the contact portions 402a and 402b.

[0027] (Step S2) The operator uses a proportional controller to fly the high-pressure cleaning drone 10 toward the object to be cleaned.

[0028] (Step S3) Based on the operator's input, the cleaning solution is sprayed from the nozzle 50 and directed towards the wall surface W to be cleaned. At this time, the operator can use the highly visible contact points 402a and 402b as landmarks to bring the high-pressure cleaning drone 10 closer to the wall surface W. In other words, the dimension L3 (see Figure 1) can be reduced, thus improving cleaning efficiency.

[0029] If the high-pressure cleaning drone 10 is positioned too close to the wall W, the first point of contact will be the contact points 402a and 402b, rather than the propeller 204, allowing the operator to perform the cleaning work with peace of mind. Furthermore, since contact can be made at two points, 402a and 402b, which are spaced apart on the left and right, a more stable state of the aircraft 20 is maintained compared to when contact is made at only one point. In the case of contact at only one point, a moment is generated in the aircraft 20 centered on the contact point, which can cause the aircraft 20's attitude to become unstable. In addition, in situations such as when the dirt is not being removed well, it is also possible to intentionally bring the contact parts 402a and 402b into contact with the wall surface W for cleaning.

[0030] (Step S4) After cleaning is complete, the spraying of the cleaning fluid is stopped and the operator lands the high-pressure cleaning drone 10.

[0031] By performing the above steps S1 to S4, the cleaning work is carried out using the high-pressure cleaning drone 10.

[0032] As explained above, with the high-pressure cleaning drone 10, the contact points 402a and 402b of the rod-shaped members 40a and 40b come into contact with the object to be cleaned before the propellers 204, thus reducing the possibility of damaging the aircraft body 20. At the same time, cleaning efficiency is improved because the cleaning fluid can be sprayed from a position close to the object to be cleaned.

[0033] Although embodiments of the present invention have been described above, the present invention is not limited to the above-described forms, and any changes to the conditions, etc., that do not depart from the gist of the invention are all within the scope of application of the present invention.
