Description

Technical Field

[0001] The present application relates to the technical field of unmanned aerial vehicles, and more specifically, to a spray cleaning device for high-altitude cleaning unmanned aerial vehicles. Background Art

[0002] Photovoltaic glass panels are usually installed in open areas or on the roofs of factory buildings. If they are not cleaned for a long time, dust will inevitably accumulate on the photovoltaic panels, reducing their ability to receive light and causing the photovoltaic panels' power generation efficiency to drop.

[0003] Compared with traditional manual cleaning methods, drones can quickly cover large areas of photovoltaic panels. Photovoltaic projects above megawatt level are large in scale, and manual cleaning is time-consuming and labor-intensive. Drones can complete the cleaning task of photovoltaic panels in a shorter time. Photovoltaic power stations are usually set up in relatively open areas. Manual cleaning may face safety risks such as high-altitude operations. Drone cleaning can avoid people being directly in dangerous environments at high altitudes, reducing the probability of safety accidents.

[0004] However, when a drone is flying over water, the water will shake due to the inertia generated during the flight. Once the shaking of the water is too large, it will cause great interference to the normal flight of the drone.

DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0037] In order to make the purpose, technical solutions and advantages of the implementation methods of this application clearer, the technical solutions in the implementation methods of this application will be clearly and completely described below in conjunction with the drawings in the implementation methods of this application. Obviously, the described implementation methods are part of the implementation methods of this application, not all of the implementation methods. Based on the implementation methods in this application, all other implementation methods obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0038] Embodiment 1, as Figure 1-Figure 13 As shown, a spray cleaning device for a high-altitude cleaning drone according to an embodiment of the present application includes an aircraft 1, four legs 11 are evenly arranged on the bottom side of the aircraft 1, and high-definition probes 12 are respectively arranged on the bottom sides of the four rotors of the aircraft 1.

[0039] It should be noted that in the specific embodiment of the present application, the aircraft 1 is a four-wing UAV to ensure that it has a certain stability during water-carrying flight. At the same time, the high-definition probe 12 is used to detect the photovoltaic panel to ensure the efficiency and accuracy of cleaning.

[0040] Specifically, a spray washing device supporting a high-altitude cleaning drone in an embodiment of the present application also includes four legs 11 with a mounting seat 13 horizontally arranged, a water tank 2 is arranged on the upper side of the mounting seat 13, and the cross-section of the water tank 2 is two cones that are symmetrical up and down. This design of the water tank 2 can increase its internal volume within the installation range and increase the carrying capacity of the water body. A spray mechanism 3 connected to the water tank 2 is arranged on the bottom side of the mounting seat 13.

[0041] Among them, Figure 1-Figure 3 As shown, the mounting seat 13 includes a mounting plate 131 and a mounting frame 132 . The mounting frame 132 is evenly fixed to the mounting plate 131 in the circumferential direction, and one end of the mounting frame 132 away from the mounting plate 131 is fixed to the support leg 11 .

[0042] like Figure 4 and Figure 5 As shown, the water tank 2 includes a box body 21 , a water injection nozzle 22 is arranged on the side wall of the box body 21 , and a drain port 23 is arranged at the bottom end of the box body 21 .

[0043] The spray mechanism 3 includes a water pump 31 and an adjustment component 32 fixedly connected to the mounting base 13. The water pump 31 is connected to the water tank 2. The adjustment component 32 is provided with a spray head 33 connected to the water pump 31. Specifically, Figure 3 As shown, the adjustment component 32 includes a horizontal turntable 321, a first motor 322, a vertical turntable 323 and a second motor 324. The horizontal turntable 321 is rotatably arranged on the mounting base 13; the first motor 322 is arranged on the horizontal turntable 321 and provides power for the horizontal turntable 321; the vertical turntable 323 is arranged at the rotating end of the horizontal turntable 321; the second motor 324 is arranged on the vertical turntable 323 and provides power for the vertical turntable 323, and the nozzle 33 is mounted on the rotating end of the vertical turntable 323. It can be seen that the angle of the nozzle 33 can be changed by the horizontal turntable 321 and the vertical turntable 323 to facilitate the correction of the cleaning angle.

[0044] It should be noted that in the specific embodiment of the present application, the horizontal turntable 321 and the vertical turntable 323 are prior art, and the specific structure will not be repeated here. It is sufficient to change the angle in two planes.

[0045] Among them, a vertical suppression mechanism 4 is also coaxially arranged in the water tank 2, and the vertical suppression mechanism 4 includes a plurality of coaxially arranged annular enclosures, and the heights of the plurality of annular enclosures gradually decrease from the inside to the outside. The slope formed by the heights of the plurality of annular enclosures is adapted to the conical cross-section of the upper half of the water tank 2. The bottom ends of the plurality of annular enclosures are all provided with through holes, and a floating device is slidably arranged between two adjacent annular enclosures.

[0046] Among them, Figure 4-Figure 6As shown, the multiple annular enclosures are respectively the first baffle ring 41, the second baffle ring 42, the third baffle ring 43 and the fourth baffle ring 44 from the inside to the outside, and the upper end surface heights of the first baffle ring 41, the second baffle ring 42, the third baffle ring 43 and the fourth baffle ring 44 decrease successively, and the lower ends of the first baffle ring 41, the second baffle ring 42, the third baffle ring 43 and the fourth baffle ring 44 are all uniformly provided with multiple flow grooves 48 in the circumferential direction. It should be noted that the setting of the flow grooves 48 can make the water bodies between each enclosure connected, so as to avoid the water bodies from being unable to circulate in the water tank 2.

[0047] Furthermore, the floating devices slidably arranged between two adjacent annular enclosures are respectively a first floating ring 45, a second floating ring 46 and a third floating ring 47. The first floating ring 45 is slidably arranged between the first retaining ring 41 and the second retaining ring 42, the second floating ring 46 is slidably arranged between the second retaining ring 42 and the third retaining ring 43, and the third floating ring 47 is slidably arranged between the third retaining ring 43 and the fourth retaining ring 44.

[0048] A first outer retaining ring lower 411 and a first outer retaining ring upper 412 are fixedly provided on the outer wall of the first floating ring 45, and a second inner retaining ring lower 421 and a second inner retaining ring upper 422 are fixedly provided on the inner wall of the second retaining ring 42. The first outer retaining ring lower 411 and the second inner retaining ring lower 421 are of the same height, and the first outer retaining ring upper 412 and the second inner retaining ring upper 422 are of the same height. The first floating ring 45 is arranged between the first outer retaining ring lower 411, the second inner retaining ring lower 421, the first outer retaining ring upper 412 and the second inner retaining ring upper 422.

[0049] A second outer retaining ring lower 423 and a second outer retaining ring upper 424 are fixedly disposed on the outer wall of the second retaining ring 42, and a third inner retaining ring lower 431 and a third inner retaining ring upper 432 are fixedly disposed on the inner wall of the third retaining ring 43. The second outer retaining ring lower 423 and the third inner retaining ring lower 431 are of the same height, and the second outer retaining ring upper 424 and the third inner retaining ring upper 432 are of the same height. The second floating ring 46 is disposed between the second outer retaining ring lower 423, the third inner retaining ring lower 431, the second outer retaining ring upper 424 and the third inner retaining ring upper 432.

[0050] A third outer retaining ring lower 433 and a third outer retaining ring upper 434 are fixed on the outer wall of the third retaining ring 43, and a fourth inner retaining ring lower 441 and a fourth inner retaining ring upper 442 are fixed on the inner wall of the fourth retaining ring 44. The third outer retaining ring lower 433 and the fourth inner retaining ring lower 441 are of the same height, and the third outer retaining ring upper 434 and the fourth inner retaining ring upper 442 are of the same height. The third floating ring 47 is arranged between the third outer retaining ring lower 433, the third outer retaining ring upper 434, the third outer retaining ring lower 433 and the fourth inner retaining ring lower 441.

[0051] By setting the retaining rings on the adjacent enclosures, the floating rings between the adjacent enclosures are limited to prevent the floating rings from leaving the range of the enclosures under the action of buoyancy.

[0052] It should be noted that the materials of the first floating ring 45, the second floating ring 46 and the third floating ring 47 are selected so that they can float in the water body, and the floating rings are used to suppress the shaking of the water surface and the water body.

[0053] Among them, the first floating ring 45, the second floating ring 46 and the third floating ring 47 have the same structure, and multiple grooves 49 are evenly arranged on the inner and outer sides of the three. It can be understood that the design of multiple grooves 49 allows the water level to continue to rise after the floating ring floats to the highest point. This design can keep the water storage capacity in the water tank 2 unaffected.

[0054] The following describes the use process of a spray cleaning device for a high-altitude cleaning drone according to an embodiment of the present application with reference to the accompanying drawings:

[0055] Before use, water is poured into the water tank 2 through the water injection nozzle 22. After the water enters the water tank 2, since a plurality of flow slots 48 are provided at the bottom of each enclosure, the water can fill the entire water tank 2. As the water level rises, a plurality of floating rings will gradually rise with the water level between their respective corresponding enclosures under the action of buoyancy until they are blocked by the corresponding retaining rings. Since a plurality of grooves 49 are provided on the inner and outer sides of the floating rings, the water can smoothly pass through the corresponding floating rings, so that the water level can continue to rise. During use, the aircraft 1 is controlled to take off above the photovoltaic panel that needs to be cleaned, and the high-definition probe 12 detects the photovoltaic panel to determine the flight altitude, flight path, hovering position and other information, and then By adjusting the direction of the nozzle 33, the water in the water tank 2 is pumped to the nozzle 33 through the water pump 31 and sprayed to the photovoltaic panel to clean the photovoltaic panel (of course, in the specific embodiment of the present application, the spray cleaning device supporting the high-altitude cleaning drone is not limited to cleaning the photovoltaic panel). During the flight, due to inertia, the water in the water tank 2 will inevitably shake. At this time, a plurality of coaxially arranged first baffle rings 41, second baffle rings 42, third baffle rings 43 and fourth baffle rings 44 will divide the water to avoid the water from shaking significantly due to inertia when it forms a separate whole. Although the plurality of baffle rings divide the water in the water tank 2 A plurality of smaller cavities are formed, and the water body will still sway due to inertia in the small cavities. At this time, the first floating ring 45, the second floating ring 46 and the third floating ring 47 between the enclosures will further suppress the water surface and the water body by themselves. Because the floating rings can and can only undergo axial displacement between adjacent enclosures, the irregular direction of the force caused by the swaying of the water body will be suppressed by the floating rings. In particular, in the present application, because the rising height of each floating ring is different, some floating rings will be located on the water surface and some floating rings will be located in the water body. In this case, the water body is further divided at the corresponding floating ring positions. Such a design will enhance the suppression of water swaying. At the same time, because the height of each enclosure is different, the floating rings located at the third floating ring 47 are located at the fourth floating ring. Even if the water above the floating ring produces a certain amount of shaking, it will still be suppressed by the corresponding enclosure. As the nozzle 33 cleans the photovoltaic panel, the water in the water tank 2 will gradually decrease, and eventually the floating rings will be located on the water surface. At this time, the floating ring and the corresponding enclosure have a better effect of suppressing the shaking of the water. The high-definition probe 12 can monitor the cleaning effect in real time. If stubborn stains are found, the nozzle 33 can be aimed at the stubborn stains for cleaning in real time through the adjustment component 32. This design of the present application can well guarantee the stability of the aircraft 1 during the flight and the cleaning process, avoid the shaking of the water body from having an adverse effect on the flight of the aircraft 1, and can effectively improve the cleaning effect and cleaning efficiency to a certain extent.

[0056] In the related art, this high-altitude cleaning drone is equipped with a spraying device. Although a plurality of enclosures and corresponding floating rings are coaxially arranged in the water tank 2 to suppress the shaking of the water body, in order to ensure the volume inside the water tank 2, it is impossible to set too many enclosures and floating rings. Therefore, there will be a large amount of blank space, especially at the axis position. Due to the shape design of the water tank 2, the volume at the axis will also be the largest. Therefore, the effect of suppressing the shaking of the water body at the axis of the water tank 2 will decrease, which will more or less bring certain adverse factors to the flight of the aircraft 1.

[0057] Embodiment 2, according to some embodiments of the present application, such as Figure 7-Figure 11 As shown, a lateral restraining mechanism 5 is arranged at the axis center of the water tank 2, and the lateral restraining mechanism 5 includes a power member 51, a guide shaft 52 and a floating plate 53. The power member 51 is rotatably arranged at the drain outlet 23; the guide shaft 52 is coaxially fixed to the upper end surface of the power member 51; and a plurality of floating plates 53 are limitedly slidably arranged on the guide shaft 52.

[0058] Specifically, Fig. 9 As shown, the power member 51 includes an upper pressing block 511, a base 512, a special-shaped cavity 513 and an arc plate 514. The cross-section of the upper pressing block 511 is a cone with an inwardly concave arc on the side; the base 512 is rotatably connected to the drain outlet 23, the base 512 is tubular, and the cross-section of the tubular base 512 is a radially open setting at the upper end; the space between the upper pressing block 511 and the base 512 is the special-shaped cavity 513; a plurality of arc plates 514 are evenly arranged at the top of the special-shaped cavity 513 in the circumferential direction, and the plurality of arc plates 514 are respectively fixed to the upper pressing block 511 and the base 512.

[0059] Through the above design, it can be understood that the multiple arc plates 514 divide the special-shaped cavity 513 into multiple arc-shaped channels. In this way, when the water body passes through the multiple arc-shaped channels from the water tank 2 and enters the water pump 31, it will provide rotational power to the entire power component 51, and as the continuous water flow passes, it will eventually drive the entire power component 51 to rotate.

[0060] like Fig.10 As shown, the first slide groove 521, the second slide groove 522, the third slide groove 523 and the fourth slide groove 524 are evenly arranged axially on the side wall of the guide shaft 52, the bottom ends of the first slide groove 521, the second slide groove 522, the third slide groove 523 and the fourth slide groove 524 are flush, and the lengths of the first slide groove 521, the second slide groove 522, the third slide groove 523 and the fourth slide groove 524 increase successively and equally.

[0061] Furthermore, the structures of the multiple floating plates 53 are exactly the same in size, and the multiple floating plates 53 are provided with multiple arc-shaped through grooves 531 in the shape of concentric rings. It can be understood that the design of the arc-shaped through grooves 531 will allow water to pass through the floating plates 53. The axis of the multiple floating plates 53 is fixedly connected with a limit block 532, and the multiple limit blocks 532 are slidably adapted to the first slide groove 521, the second slide groove 522, the third slide groove 523 and the fourth slide groove 524 respectively.

[0062] It should be noted that, in the specific embodiment of the present application, the material selection of the plurality of floating plates 53 needs to enable the floating plates 53 to float in water.

[0063] Therefore, when it is used, the flow of water will drive the entire power member 51 to rotate, so the guide shaft 52 on the upper end surface of the power member 51 will follow the rotation, and the guide shaft 52 is provided with a plurality of floating plates 53 for sliding, and the plurality of floating plates 53 slide in the first slide groove 521, the second slide groove 522, the third slide groove 523 and the fourth slide groove 524 respectively. It can be understood that when the water in the water tank 2 is full, the plurality of floating plates 53 will form a Figure 4 In the state of the middle, the buoys 53 arranged at intervals will suppress the shaking of the water to a certain extent. Because the buoys 53 can and can only undergo axial displacement on the guide shaft 52 through the limit block 532, when the guide shaft 52 rotates, the multiple buoys 53 will be driven to rotate synchronously. In this way, the buoys 53 in the rotation process and the multiple arc-shaped through grooves 531 thereon will form a certain degree of cutting on the water body, and the shaking of the water body will be suppressed. The rotating buoys 53 will cause the water body to be subjected to a certain degree of centrifugal force, further suppressing the shaking of the water body. As the water body decreases during the cleaning process, the buoys 53 will gradually descend with the water surface. During the descent, the number of buoys 53 located at the water surface will gradually increase, and further suppress the shaking of the water body from the water surface direction. Therefore, multiple buoys 53 that can rise with the water surface will suppress the shaking of the water body at the axis of the water tank 2, reducing the adverse effects of the shaking of the internal water body of the entire water tank 2 on the stable flight of the aircraft 1.

[0064] In the related art, this high-altitude cleaning drone is equipped with a spraying device. The size of the water tank 2 is limited, and the water inside it should carry as much water as possible to reduce the number of times the aircraft 1 goes back and forth to replenish water. Therefore, the number and design of the vertical suppression mechanism 4 and the horizontal suppression mechanism 5 inside it will minimize the occupancy of the internal volume of the water tank 2. In this way, the water in the water tank 2 will inevitably shake to a certain extent during the flight of the aircraft 1, which will still have a certain impact on the stable flight of the aircraft 1.

[0065] Embodiment 3, according to some embodiments of the present application, such as Fig.12 and Fig.13 As shown, a boosting mechanism 6 is coaxially arranged at the top of the water tank 2, and the boosting mechanism 6 includes a boosting cabin 61, a boosting plate 62 and a rotating column 63. The boosting cabin 61 is coaxially fixed to the inner top of the water tank 2, and the boosting cabin 61 is cylindrical with openings at both ends; the boosting plate 62 is sealingly limited and slides on the boosting cabin 61; the rotating column 63 is threadedly connected to the top of the water tank 2, and the rotating column 63 is rotatably connected to the boosting plate 62.

[0066] Among them, the bottom end of the inner wall of the pressurized cabin 61 is coaxially fixed with a limiting ring 611.

[0067] Furthermore, the interior of the rotating column 63 is coaxially connected to a one-way valve 631 .

[0068] It should be noted that, in the specific embodiment of the present application, the direction of the one-way valve 631 is from outside to inside.

[0069] Therefore, it can be understood that before filling water into the water tank 2, the boosting plate 62 is raised to the top of the boosting chamber 61 by rotating the rotating column 63. After the water in the water tank 2 is injected to the limit (the water surface is below the boosting chamber 61, that is, there is space between the water surface and the boosting chamber 61), the water injection nozzle 22 is closed, and the rotating column 63 is rotated in the direction to drive the boosting plate 62 to move downward in the boosting chamber 61 until it moves to the limit ring 611. During this process, the volume in the water tank 2 gradually decreases, while the volume of the water body remains unchanged, so a gradually increasing pressure will be formed above the water surface, and the entire water body will be subjected to pressure from above. In this way, when using During use, the pressure above the water surface will also have a certain inhibitory effect on the shaking of the water body. With use, the water level will gradually drop, and the originally compressed space above the water surface will gradually recover and expand. At this time, the pressure on the water surface will gradually decrease. The design of the one-way valve 631 can prevent the water level from dropping and causing negative pressure to form inside the water tank 2, that is, to prevent the water body from being smoothly pumped by the water pump 31. The design of the present application suppresses the possible shaking of the water body to the greatest extent, ensures the stability of the aircraft 1 during the water-carrying flight, ensures the safety of the aircraft 1, and also improves the carrying capacity of the aircraft 1 to a certain extent.

[0070] It should be noted that the specific models and specifications of the aircraft 1, high-definition probe 12, water pump 31, nozzle 33, horizontal turntable 321, first motor 322, vertical turntable 323, second motor 324 and one-way valve 631 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail.

[0071] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
