DETAILED DESCRIPTION

[0027] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0028] The utility model proposes a cleaning device 100 and a cleaning system 1000, which can realize high-altitude operation, improve cleaning efficiency, and do not require manual cleaning, thereby improving safety.

[0029] Reference Figures 1 to 4 According to the cleaning device 100 in the embodiment of the utility model, the cleaning device 100 is mainly used to clean the top of a city subway entrance or passage entrance, as well as solar photovoltaic panels.

[0030] The cleaning device 100 includes a frame 10 , a lifting mechanism 20 , a transfer platform 30 and a cleaning module 40 .

[0031] The frame 10 has a walking assembly 11, and the lifting mechanism 20 is arranged on the frame 10 and can be extended and retracted in the up and down direction. The transfer platform 30 is connected to the lifting mechanism 20 and driven to be lifted and lowered by the lifting mechanism 20. The cleaning module 40 is located on the transfer platform 30 and can be driven away from the transfer platform 30 and driven to be lifted and lowered by the lifting mechanism 20; wherein the transfer platform 30 has an unfolded position for guiding the cleaning module 40 to move to the working area; specifically, during operation, the frame 10 can be moved to the working place by the walking assembly 11, and then the lifting mechanism 20 can drive the transfer platform 30 to lift To a predetermined height, it is convenient to clean the top area. There is a cleaning module 40 on the transfer platform 30. The transfer platform 30 can guide the cleaning module 40 to leave the transfer platform 30 in the expanded position and move it to the working area. After the cleaning module 40 is in place, it can work according to a predetermined procedure, that is, to clean the area located at the top. During this process, no manual cleaning is required, and the lifting and lowering of the cleaning module 40 can be achieved through the lifting mechanism 20; then, the cleaning module 40 can return to the transfer platform 30 along the original route after cleaning, and the transfer platform 30 can be driven down by the lifting mechanism 20.

[0032] Therefore, according to the cleaning device 100 in the embodiment of the utility model, high-altitude operations can be achieved, the cleaning efficiency can be improved, and manual cleaning is not required, thereby improving safety.

[0033] In the operation scene, for example, a city subway entrance, there are usually green belts planted near it and steps arranged, which makes it impossible for the cleaning device 100 to approach the operation site. Figure 1 to Figure 2 In some embodiments of the present invention, the cleaning device 100 further includes a lap joint mechanism 50, which is rotatably connected to the transfer platform 30 and has an unfolded state and a folded state, so that the cleaning device 100 can clean the working area.

[0034] During operation, the frame 10 is moved to the working site through the walking assembly 11, and the transfer platform 30 and the overlapping mechanism 50 are driven to be lifted to a predetermined height through the lifting mechanism 20. At this time, the transfer platform 30 can be switched to the expanded position, and the overlapping mechanism 50 can be switched to the expanded state. In the expanded state, the overlapping mechanism 50 is overlapped with the working area to construct a first driving channel 54 suitable for the cleaning module 40 to pass through. In this way, the cleaning module 40 can leave the transfer platform 30, move to the working area through the first driving channel 54, and clean the working area according to a predetermined procedure, and after cleaning, return to the transfer platform 30 along the first driving channel 54; then, the overlapping mechanism 50 can be switched to the folded state, and in the folded state, the overlapping mechanism 50 is stored in the transfer platform 30, thereby completing the cleaning of the working area by the cleaning device 100.

[0035] Further, refer to Figure 1 and Figure 2In some embodiments of the present invention, the overlapping mechanism 50 includes a first part 51 and a second part 52, the first part 51 is rotatably connected to the transfer platform 30, and the second part 52 is rotatably connected to the first part 51, so that the cleaning device 100 can clean the working area.

[0036] Among them, when the overlapping mechanism 50 switches to the folded state, the first part 51 can be rotated relative to the second part 52 so that the first part 51 and the second part 52 are folded up; when the overlapping mechanism 50 switches to the unfolded state, the first part 51 can be rotated relative to the second part 52 so that the first part 51 and the second part 52 are unfolded to form a first driving channel 54, which is suitable for the cleaning module 40 to pass through.

[0037] Of course, according to actual conditions, the overlapping mechanism 50 may also include a third part 53, a fourth part, etc.; in some specific examples, the overlapping mechanism 50 includes a first part 51, a second part 52 and a third part 53, the second part 52 is rotatably connected to the first part 51, and the third part 53 is rotatably connected to the first part 51. In the unfolded state, the first part 51, the second part 52 and the third part 53 are rotated to form a straight line shape, thereby constructing a first driving channel 54; in the folded state, the first part 51, the second part 52 and the third part 53 are folded in a "Z" shape; compared with the situation in which multiple parts are flipped and folded in the same direction in the related art, the embodiments of the utility model can facilitate the rapid unfolding and rapid folding of the overlapping mechanism 50.

[0038] Reference Figure 5 In some embodiments of the utility model, the overlapping mechanism 50 includes a main body 501 and a limiting portion 502. The main body 501 is rotatably connected to the transfer platform 30 and extends along a first direction. A first driving channel 54 is constructed on the surface. The limiting portion 502 is respectively arranged on two opposite sides of the main body 501 in the vertical direction along the first direction and protrudes from the surface of the main body 501. In this way, the cleaning module 40 can be limited to prevent the cleaning module 40 from falling from the overlapping mechanism 50.

[0039] Specifically, the main body 501 extends along the first direction, and the surface of the main body 501 constructs a first driving channel 54. In other words, the first driving channel 54 also extends along the first direction; and a limiting portion 502 may be provided on one side of the main body 501 vertically along the first direction, and a limiting portion 502 may also be provided on the other side vertically along the first direction, and the limiting portions 502 on both sides protrude from the surface of the main body 501; when the cleaning module 40 moves on the surface of the main body 501, it can be restricted by the limiting portion 502 to prevent the cleaning module 40 from falling from the overlapping mechanism 50, thereby improving the operating stability of the cleaning device 100.

[0040] The aforementioned overlapping mechanism 50 can be driven to switch between the unfolded state and the folded state by setting a driving member, or it can be switched manually; for example, referring to Figures 1 to 3 In some embodiments of the utility model, the cleaning device 100 also includes a lifting platform 60, which is connected to the lifting mechanism 20 and driven to rise and fall by the lifting mechanism 20 for carrying people; specifically, a technician can be located in the lifting platform 60 to control the lifting and falling of the lifting mechanism 20, and can manually drive the overlapping mechanism 50 to switch between a folded state and an unfolded state, so that the cleaning device 100 can clean the working area.

[0041] Reference Figure 1 and Figure 2 In some embodiments of the present invention, the cleaning device 100 further includes a rotating portion 70 and a supporting portion 80, one end of the rotating portion 70 is rotatably connected to the frame 10, and the other end is connected to the supporting portion 80; such an arrangement can improve the operating stability of the cleaning device 100.

[0042] Specifically, under normal circumstances, the rotating part 70 and the supporting part 80 are stored in the frame 10; when the cleaning device 100 is operating, in order to improve the operating stability of the cleaning device 100, the rotating part 70 can be driven to rotate relative to the frame 10 so that the supporting part 80 is swung out from the frame 10. At this time, the supporting part 80 can be supported on the road surface to provide better supporting performance for the cleaning device 100, thereby improving the operating stability of the cleaning device 100.

[0043] Further, refer to Figure 1 and Figure 2 In some embodiments of the present invention, the other end of the rotating part 70 is threadedly connected to the supporting part 80 for adjusting the height of the supporting part 80 from the ground so as to support it on the road surface; the cleaning device 100 arranged in this way can be suitable for road surfaces in different scenarios, thereby improving the applicability of the cleaning device 100.

[0044] After the rotating part 70 drives the supporting part 80 to swing out relative to the frame 10, since the other end of the rotating part 70 is threadedly connected to the supporting part 80, the technician can rotate the supporting part 80 to convert the rotational motion of the supporting part 80 into the linear motion of the supporting part 80, thereby adjusting the height of the supporting part 80 from the ground to support the supporting part 80 on the road surface. In other words, the supporting part 80 can be adjusted according to different road surface conditions so that the cleaning device 100 can be stably supported on the road surface, thereby improving the stability of the operation. In addition, referring to Figure 1 and Figure 2 In some specific examples, the rotating parts 70 include multiple, the supporting parts 80 include multiple, and the multiple supporting parts 80 are respectively arranged in a one-to-one correspondence with the multiple rotating parts 70 to further improve the supporting stability of the cleaning device 100 on the road surface.

[0045] In some embodiments of the present invention, the cleaning module 40 includes a contact cleaning module 40 and a non-contact cleaning module 40. The contact cleaning module 40 is used to sweep and clean the working surface; specifically, the contact cleaning module 40 can directly contact the surface of the object to be cleaned, and usually uses a brush, a wiping cloth or a sponge to clean; the non-contact cleaning module 40 is used to spray a medium toward the cleaning area to clean the working surface; specifically, the non-contact cleaning module 40 can avoid contact with the working surface, and spray the cleaning medium toward the working surface by using high-pressure gas or liquid to remove dirt and particles on the working surface, which is convenient for operation and avoids the safety risk of contacting the working surface.

[0046] Reference Figures 1 to 4 In some embodiments of the utility model, the lifting mechanism 20 may include a first lifting part 21, a second lifting part 22 and a driving part 23, the first lifting part 21 is arranged on the frame 10, the second lifting part 22 is slidably connected to the first lifting part 21 along the up-down direction, and the driving part 23 is configured to drive the second lifting part 22 to slide relative to the first lifting part 21; specifically, one of the first lifting part 21 and the second lifting part 22 may be provided with a slide groove, and the other may be provided with a slider, both of the slide groove and the slider extend along the up-down direction, and the slider is slidably embedded in the slide groove, so that under the driving action of the driving part 23, the second lifting part 22 can be lifted and lowered along the up-down direction relative to the first lifting part 21 to realize the lifting function of the lifting mechanism 20.

[0047] Of course, according to actual conditions, the lifting mechanism 20 may also include a third lifting part, a fourth lifting part, etc., to increase the lifting height of the lifting mechanism 20. In addition, compared with the scissor mechanism used in the related art to achieve lifting, the lifting mechanism 20 in the embodiment of the utility model can reduce the occupied space, making it easier for the cleaning device 100 to perform cleaning operations in a narrow space.

[0048] Reference Figures 1 to 4 According to the cleaning system 1000 in the embodiment of the utility model, the cleaning system 1000 includes a transfer device 200 and the cleaning device 100 in the above embodiment. The transfer device 200 includes a chassis 210. The cleaning device 100 is arranged on the transfer device 200. By applying the aforementioned cleaning device 100, high-altitude operations can be achieved, the cleaning efficiency is improved, and manual cleaning is not required, thereby improving safety; and through the transfer device 200, the cleaning range of the cleaning system 1000 can be increased.

[0049] Specifically, the cleaning device 100 can be set on the chassis 210 of the transfer device 200, and the cleaning device 100 can be transported by the transfer device 200, so that the cleaning device 100 can be operated at multiple work sites, thereby increasing the cleaning range of the cleaning system 1000; during operation, the transfer device 200 can first transport the cleaning device 100 to a road surface close to the work site, and lower the cleaning device 100 from the transfer device 200 to the road surface, and then the cleaning device 100 can be moved to the work site through the walking component 11, and the technician can be located on the lifting platform 60 to control the lifting mechanism 20 is lifted to lift the transfer platform 30 and the overlapping mechanism 50 to a predetermined height. At this time, the overlapping mechanism 50 can be switched to the unfolded state to construct a first driving channel 54 between the transfer receipt and the working area, so that the cleaning module 40 can be conveniently moved to the working area through the first driving channel 54. Subsequently, the cleaning module 40 can be cleaned according to a predetermined procedure, and after cleaning, it can return to the transfer platform 30 through the first driving channel 54 again. Then the overlapping mechanism 50 can be switched to the folded state, and the technician can control the lifting mechanism 20 to drive the transfer platform 30 and the overlapping mechanism 50 to descend.

[0050] Furthermore, the transfer device 200 also includes a bracket 220, which is connected to the chassis 210. The cleaning device 100 is placed on the bracket 220 and can be lowered from the bracket 220; specifically, the transfer device 200 walks on the road surface through the chassis 210, and transfers the cleaning device 100 through the bracket 220, thereby improving the cleaning range of the cleaning system 1000.

[0051] Furthermore, the transfer device 200 further includes a reversing ladder 230, which is rotatably connected to the bracket 220 and is used to construct a second driving channel 240 suitable for the rack 10 to pass through, and the rack 10 enters and leaves the bracket 220 through the second driving channel 240; specifically, the reversing ladder 230 is rotatably connected to the bracket 220 to rotate relative to the bracket 220; in a normal state, the reversing ladder 230 is erected on the bracket 220, at which time the cleaning device 100 can be placed on the bracket 220, and the cleaning device 100 can be placed on the bracket 220 by the erected reversing ladder 230. The ladder 230 restricts the cleaning device 100 from leaving the bracket 220, making it convenient for the transfer device 200 to transfer the cleaning device 100; when the cleaning device 100 needs to be lowered, the reversible ladder 230 can rotate relative to the bracket 220 so that the reversible ladder 230 abuts against the road surface, thereby constructing a second driving channel 240 between the road surface and the bracket 220. At this time, the cleaning device 100 can be lowered from the bracket 220 to the road surface through the second driving channel 240, and then the cleaning device 100 is pushed to the work site by the technician. In addition, after the cleaning device 100 completes cleaning, it can also be recovered from the road surface to the bracket 220 through the second driving channel 240 constructed by the reversible ladder 230.

[0052] Of course, according to actual conditions, the reversible ladder 230 can be extended and retracted relative to the bracket 220. When the cleaning device 100 is placed on the bracket 220, the reversible ladder 230 can be retracted in the bracket 220. When the cleaning device 100 needs to be lowered or lowered from the bracket 220, the reversible ladder 230 can extend from the bracket 220 and tilt toward the road surface to abut against the road surface, thereby constructing a second driving channel 240 between the road surface and the bracket 220 to facilitate the lowering and lowering of the cleaning device 100 from the bracket 220 to the road surface. The aforementioned reversible ladder 230 can be provided with a driving member on the chassis 210, and the driving member can drive the reversible ladder 230 to move relative to the bracket 220, thereby realizing the lowering and recovery of the cleaning device 100.

[0053] In some embodiments of the present invention, the transfer device 200 may further include a water system, which is disposed on the chassis 210 and is connected to the cleaning module 40 through a pipeline for supplying water to the cleaning module 40. This arrangement can provide cleaning liquid to the cleaning module 40, facilitating the cleaning operation of the cleaning module 40.

[0054] In detail, the water system includes a water tank 250 and a water pump. The water tank 250 is connected to the cleaning module 40 through a pipeline. The water pump is connected to the water tank 250 and is used to drive the water in the water tank 250 to flow to the cleaning module 40 to provide cleaning water for the cleaning module 40, thereby facilitating the cleaning operation of the cleaning module 40.

[0055] The utility model provides a cleaning system 1000, which can be used for cleaning the ceilings of buildings such as urban subway entrances and passageways, and can also be used for cleaning solar photovoltaic panels. The cleaning device 100 is mounted on a transfer device 200, and the transfer device 200 drags the information device to the roadside of the operation target. The cleaning device 100 is equipped with universal wheels (i.e., walking components 11) at the bottom, and the cleaning device 100 can be manually pushed to the vicinity of the operation target. The frame 10 of the cleaning device 100 is equipped with four legs (i.e., support parts 80 and rotating parts 70), and the legs need to be opened during operation to ensure the stability of the entire device. The elevator (i.e., the lifting mechanism 20) is fixed on the frame 10, and is made of aluminum alloy. The chain gear is driven by a motor to lift the operator, the cleaning module 40 and the aluminum alloy folding ladder (i.e., the lap mechanism 50) to the required height. The operator unfolds the folding ladder and puts it on the ceiling to be cleaned, and the cleaning module 40 can automatically travel to the ceiling with the help of the folding ladder to perform cleaning operations. The cleaning module 40 has two types: contact type and non-contact type to meet different ceiling shapes. The cleaning module 40 can perform automatic cleaning operations through a preset path through the program, or it can be manually operated through the remote control screen. During the cleaning process, the water source of the cleaning module 40 is taken from the water tank 250 of the transfer device 200, and the water hose reel can be extended to the working platform to directly supply water to the cleaning module 40.

[0056] In some specific examples of the present invention, the cleaning system 1000 may include: a chassis 210 of a transfer device 200, a cleaning device 100, a bracket 220, a connecting frame, and a folding ladder. The cleaning device 100 may include a cleaning module 40, a lifting platform 60, a lifting ladder, a frame 10, and legs.

[0057] Among them, the implementation path of the cleaning system 1000 is:

[0058] The cleaning device 100 is fixed on the bracket 220, and the bracket 220 is connected to the chassis 210 of the transfer device 200 through a connecting frame, and is transferred by the transfer device 200 to the vicinity of the work target. The cleaning device 100 can be pushed from the bracket 220 to the ground through the flip ladder 230. Four universal wheels are installed under the frame 10. The width of the cleaning device 100 meets the requirements of the pedestrian passage and can be manually pushed to the vicinity of the subway entrance. In order to improve the stability of the cleaning device 100, four legs need to be unfolded. The lifting platform 60 is installed on the end ladder of the lifting mechanism 20. The lifting mechanism 20 completes the lifting and lowering through the motor-driven chain transmission, and lifts the cleaning module 40, the folding ladder and the operator located on the lifting platform 60 to a suitable height. The operator opens the folding ladder and puts it on the ceiling. The cleaning module 40 has its own crawler walking mechanism, which is driven by a motor and can be run to the working ceiling through the folding ladder. The cleaning module 40 is connected to a water pipe, and the other end of the water pipe is connected to the water pipe reel of the transfer device 200, and the transfer device 200 provides water for cleaning operations.
