Description

Technical Field

[0001] This application belongs to the field of automation equipment technology, and more specifically, relates to a cleaning device. Background Technology

[0002] Streetlights used in outdoor environments need to be cleaned regularly. Due to the large vertical height of streetlights, manual cleaning requires the use of ladders or lifts for high-altitude operations, which is quite dangerous. Therefore, cleaning equipment is often used to replace manual labor.

[0003] The existing cleaning device includes a clamping structure, a cleaning brush, and a working box. The clamping structure is fitted around the periphery of the street light. The cleaning brush and the working box are both connected to the clamping structure. The working box is used to drive the clamping structure to move on the street light. The street light can be cleaned by the mutual friction between the bristles of the cleaning brush and the surface of the street light.

[0004] Because the cleaning brush can only clean a portion of the street light's outer perimeter along a straight line from bottom to top each time, the angle of the cleaning brush needs to be manually adjusted and the process repeated multiple times to clean the entire outer perimeter of the street light. Furthermore, the outer diameter of the street light changes from bottom to top. When the cleaning device rises to a certain height, a gap forms between the clamping structure and the surface of the street light, preventing the cleaning device from rising further. Therefore, the cleaning device suffers from low cleaning efficiency and poor applicability. Summary of the Invention

[0005] One of the objectives of this application is to provide a cleaning device that solves the technical problems of low cleaning efficiency and poor applicability caused by the existing cleaning device. The cleaning brush of the existing cleaning device can only clean part of the outer periphery of the street lamp in a straight line from bottom to top each time. The placement angle of the cleaning brush needs to be manually adjusted and the device needs to be raised and lowered many times to clean the complete outer periphery of the street lamp. In addition, the outer diameter of the street lamp will change from bottom to top. When the cleaning device rises to a certain height, a gap will be formed between the clamping structure and the surface of the street lamp, which will prevent the cleaning device from rising further.

[0006] To address the aforementioned technical problems, in a first aspect, one embodiment of this application provides a cleaning device. The cleaning device includes a sliding table mechanism, a cleaning mechanism, and a lifting mechanism. The sliding table mechanism includes a slide base and a slider, with the slider slidably mounted on the slide base along its circumference. The cleaning mechanism includes a first displacement component and a cleaning component. The opposite sides of the first displacement component are movably connected to the cleaning component and the slider, respectively. The first displacement component is used to drive the cleaning component to move radially along the slide base. Multiple lifting mechanisms are installed at intervals along the circumference of the slide base, and the multiple lifting mechanisms cooperate to drive the slide base to move vertically along its axial direction.

[0007] The beneficial effects of the cleaning device provided in this application are as follows: By setting up a sliding table mechanism, a cleaning mechanism, and a lifting mechanism to cooperate with each other, compared with the cleaning devices in the prior art, the sliding table mechanism of this application includes a slidingly assembled slide and a slider. The cleaning mechanism can rotate along the circumference of the slide with the slider, so that the cleaning mechanism can clean the entire outer circumference of the street lamp at a certain height. The lifting mechanism can drive the slide to move up and down, so that the cleaning mechanism can clean the entire height of the street lamp from bottom to top. Thus, the cleaning mechanism can continuously and thoroughly clean all parts of the street lamp, and the cleaning efficiency of the cleaning device is higher. The first displacement component can drive the cleaning component to move radially along the slide, so that the cleaning component can maintain close contact with the surface of the street lamp. The cleaning component can still be used normally in scenarios where the outer diameter of the street lamp changes or the surface of the street lamp is uneven, and the cleaning device has stronger applicability.

[0008] In one feasible technical solution, the first displacement component includes a first linkage mechanism and a first fixed seat and a second fixed seat respectively movably installed on adjacent sides of the first linkage mechanism. The first fixed seat is equipped with a first power device, which is used to drive the entire first linkage mechanism to produce telescopic deformation. The second fixed seat is slidably connected to the cleaning component.

[0009] In one feasible technical solution, the first displacement component further includes a first buffer, and the cleaning component is provided with a transition member that is slidably assembled with the second fixed seat. The first buffer member is used to brake the relative movement between the second fixed seat and the transition member.

[0010] In one feasible technical solution, the cleaning assembly includes a third fixed base and a first driving device and a roller respectively connected to opposite sides of the inner peripheral wall of the third fixed base, wherein the inside of the roller is formed with a receiving cavity for placing the first driving device.

[0011] In one feasible technical solution, the lifting mechanism includes a second displacement component and a crawling component. The opposite sides of the second displacement component are movably connected to the crawling component and the slide, respectively. The second displacement component is used to drive the crawling component to move radially along the slide.

[0012] In one feasible technical solution, the second displacement component includes a second linkage mechanism and a first support seat and a second support seat respectively movably mounted on opposite sides of the second linkage mechanism. The first support seat is equipped with a second power device, which is used to drive the entire second linkage mechanism to produce telescopic deformation. The first support seat is rotatably connected to the crawling component.

[0013] In one feasible technical solution, the second displacement component further includes a second buffer member, which is used to brake the relative movement between the second support and the second linkage mechanism.

[0014] In one feasible technical solution, the crawling assembly includes a third support base, a second driving device fixedly connected to the third support base, and a plurality of crawling wheels rotatably connected to the third support base, wherein the output end of the second driving device is connected to the plurality of crawling wheels in a transmission connection.

[0015] In one feasible technical solution, the slide has a ring-shaped structure and includes multiple guide rail assemblies connected end to end, with the ends of adjacent guide rail assemblies being detachably connected.

[0035] The following detailed description is provided in conjunction with specific accompanying drawings and embodiments:

[0036] Please refer to the following: Figure 1 , Figure 2 and Figure 5 This application provides a cleaning device, which includes a sliding table mechanism 10, a cleaning mechanism 20, and a lifting mechanism 30. The sliding table mechanism 10 includes a slide base 11 and a slider 12. The slider 12 is slidably mounted on the slide base 11 along the circumference of the slide base 11. The cleaning mechanism 20 includes a first displacement component 21 and a cleaning component 22. The opposite sides of the first displacement component 21 are movably connected to the cleaning component 22 and the slider 12, respectively. The first displacement component 21 is used to drive the cleaning component 22 to move radially along the slide base 11. Multiple lifting mechanisms 30 are installed at intervals along the circumference of the slide base 11. The multiple lifting mechanisms 30 cooperate to drive the slide base 11 to move up and down axially.

[0037] By setting up a sliding table mechanism 10, a cleaning mechanism 20, and a lifting mechanism 30 to work together, the sliding table mechanism 10 includes a sliding base 11 and a slider 12. The cleaning mechanism 20 can rotate along the circumference of the sliding base 11 with the slider 12, so that the cleaning mechanism 20 can clean the entire outer circumference of the street lamp at a certain height. The lifting mechanism 30 can drive the sliding base 11 to move up and down, so that the cleaning mechanism 20 can clean the entire height of the street lamp from bottom to top. This allows the cleaning mechanism 20 to continuously and thoroughly clean all parts of the street lamp, resulting in high cleaning efficiency. The first displacement component 21 can drive the cleaning component 22 to move radially along the sliding base 11, so that the cleaning component 22 maintains close contact with the surface of the street lamp. The cleaning component 22 can still be used normally in scenarios where the outer diameter of the street lamp changes or the surface of the street lamp is uneven, making the cleaning device more versatile.

[0038] In applications, the cleaning device is suitable not only for cleaning streetlights, but also for cleaning cylindrical structures such as utility poles and columns.

[0039] In application, the cleaning device is also equipped with a wireless control module. The cleaning mechanism 20 and the lifting mechanism 30 are respectively equipped with distance sensors. The sliding mechanism 10, the cleaning mechanism 20 and the lifting mechanism 30 are all electrically connected to the wireless control module. The user can operate the wireless control module from the ground with a remote control to make the cleaning device perform operations such as raising, lowering, rotating and cleaning.

[0040] In one embodiment, please refer to [the relevant documentation / reference]. Figures 2 to 4 The first displacement component 21 includes a first linkage mechanism 213 and a first fixed seat 211 and a second fixed seat 212 respectively movably installed on adjacent sides of the first linkage mechanism 213. The first fixed seat 211 is equipped with a first power device 214, which is used to drive the first linkage mechanism 213 to produce an extension and contraction deformation. The second fixed seat 212 is slidably connected to the cleaning component 22.

[0041] In application, the first fixed base 211 has a first sliding groove 2001 on each of its opposite sides and a first sliding shaft 2011 is slidably installed in the first sliding groove 2001. The second fixed base 212 has a second sliding groove 2002 on each of its opposite sides and a second sliding shaft 2012 is slidably installed in the second sliding groove 2002. The extension direction of the first sliding groove 2001 is perpendicular to the extension direction of the second sliding groove 2002. There are two first linkage mechanisms 213 arranged in parallel. The two ends of the first sliding shaft 2011 and the two ends of the second sliding shaft 2012 are rotatably connected to the two first linkage mechanisms 213 respectively. The first sliding shaft 2011 and the second sliding shaft 2012 are arranged in parallel to each other so that the whole of the first linkage mechanism 213 can deform radially in the slide 11 by being driven by the first power device 214.

[0042] Specifically, the first linkage mechanism 213 includes a first link 2131, a second link 2132, a third link 2133, a fourth link 2134, a fifth link 2135, a sixth link 2136, a seventh link 2137, and an eighth link 2138. One end of the first link 2131 is rotatably connected to the first sliding shaft 2011, the other end of the first link 2131 is rotatably connected to one end of the fourth link 2134, the other end of the fourth link 2134 is rotatably connected to one end of the fifth link 2135, the other end of the fifth link 2135 is rotatably connected to one end of the eighth link 2138, and the other end of the eighth link 2138 is rotatably connected to the second link 2131. The fixed base 212, one end of the second link 2132 is rotatably connected to the first fixed base 211, the other end of the second link 2132 is rotatably connected to one end of the third link 2133, the other end of the third link 2133 is rotatably connected to one end of the sixth link 2136, the other end of the sixth link 2136 and one end of the seventh link 2137 are rotatably connected to the second sliding shaft 2012, and the other end of the seventh link 2137 is rotatably connected to the middle of the eighth link 2138. The first link mechanism 213 has a simple structure, can save materials, and reduce the overall weight of the cleaning assembly 22, so as to reduce the energy consumption generated by the cleaning assembly 22 overcoming its own gravity.

[0043] In application, the first power device 214 can be a linear actuator, a cylinder, a hydraulic cylinder, or a lead screw and nut mechanism. The output end of the first power device 214 is connected to a first drive shaft 216. The two ends of the first drive shaft 216 are respectively rotatably connected to two second linkages 2132 so that the two first linkage mechanisms 213 can move synchronously.

[0044] In one embodiment, please refer to [the relevant documentation / reference]. Figures 2 to 4 The first displacement component 21 also includes a first buffer 215, and the cleaning component 22 is provided with a transition component 221 that is slidably assembled with the second fixed seat 212. The first buffer 215 is used to brake the relative movement between the second fixed seat 212 and the transition component 221.

[0045] In application, the adapter 221 has a third slide groove 2003 on each of its opposite sides, and a third slide shaft 2013 is slidably installed in the third slide groove 2003. The third slide groove 2003 is parallel to the second slide groove 2002. The two ends of the third slide shaft 2013 are rotatably connected to the second fixed seat 212. The adapter 221 has a hollow structure. A first brake shaft 225, which is parallel to the third slide shaft 2013, is also rotatably connected inside the adapter 221. The two ends of the first buffer 215 are connected to the third slide shaft 2013 and the first brake shaft 225, respectively. The cooperation between the third slide groove 2003 and the third slide shaft 2013 can form a flexible connection between the adapter 221 and the second fixed seat 212 to improve the accuracy of the cleaning assembly 22 during operation.

[0046] In application, the first buffer 215 can be a gas spring or a damper, and two third sliding shafts 2013 are provided at intervals. The first buffer 215 is connected to the one of the two third sliding shafts 2013 that is closer to the first brake shaft 225, so as to prevent the adapter 221 from flipping relative to the second fixed seat 212.

[0047] Specifically, when the cleaning device cleans the streetlights, there is a strong mutual impact between the cleaning component 22 and the streetlights. The shaking or swaying generated by the cleaning component 22 will be transmitted to the first displacement component 21, causing the first displacement component 21 to deviate. This results in the cleaning component 22 being unable to align with the target position for cleaning. By setting the first buffer 215 and the first brake shaft 225, the sliding of the third sliding shaft 2013 in the third slide groove 2003 can be braked to reduce the deviation of the first displacement component 21, thereby ensuring that the cleaning component 22 performs the cleaning operation accurately.

[0048] In application, the outer periphery of the third sliding shaft 2013 is also fitted with a first clamping member 217. The first clamping member 217 is made of elastic material and is used to limit the horizontal movement between the second fixed seat 212 and the adapter 221 to further ensure the connection stability.

[0049] In one embodiment, please refer to [the relevant documentation / reference]. Figures 2 to 4 The cleaning assembly 22 includes a third fixed base 223 and a first driving device 224 and a roller 222 respectively connected to opposite sides of the inner peripheral wall of the third fixed base 223. The inside of the roller 222 is formed with a receiving cavity for placing the first driving device 224.

[0050] In application, the third fixing seat 223 has a frame-like structure and is fixedly connected to the end of the adapter 221 away from the second fixing seat 212. The outer peripheral wall of the roller 222 is provided with bristles. The first driving device 224 can be an electric motor. The output end of the first driving device 224 is connected to the inner peripheral wall of the roller 222 so that the roller 222 can rotate around the central axis of the third fixing seat 223, thereby cleaning the street light.

[0051] In one embodiment, please refer to [the relevant documentation / reference]. Figures 5 to 7 The lifting mechanism 30 includes a second displacement component 31 and a crawling component 32. The two sides of the second displacement component 31 are movably connected to the crawling component 32 and the slide 11, respectively. The second displacement component 31 is used to drive the crawling component 32 to move radially along the slide 11.

[0052] In application, the number of lifting mechanisms 30 is three or more. Multiple lifting mechanisms 30 are evenly spaced around the circumference of the slide 11 to avoid the slide 11 from tilting or flipping, and to ensure that the lifting movement of the slide 11 is more stable.

[0053] In one embodiment, please refer to [the relevant documentation / reference]. Figures 5 to 7 The second displacement component 31 includes a second linkage mechanism 313 and a first support seat 311 and a second support seat 312 respectively movably mounted on opposite sides of the second linkage mechanism 313. The first support seat 311 is equipped with a second power device 314, which is used to drive the second linkage mechanism 313 to produce an extension and contraction deformation. The first support seat 311 is rotatably connected to the crawling component 32.

[0054] In application, the first support base 311 has first movable grooves 3001 on its opposite sides, and a first movable shaft 3011 is slidably installed in the first movable grooves 3001. The second support base 312 has collinear second movable grooves 3002 and third movable grooves 3003 on its opposite sides. A second movable shaft 3012 is slidably installed in the second movable groove 3002, and a third movable shaft 3013 is slidably installed in the third movable groove 3003. The extending direction of the first movable groove 3001 is perpendicular to the extending direction of the second movable groove 3002. The extension direction of the second movable groove 3002 is the same as the extension direction of the third movable groove 3003. There are two second linkage mechanisms 313 arranged in parallel. The two ends of the first movable shaft 3011, the two ends of the second movable shaft 3012, and the two ends of the third movable shaft 3013 are respectively rotatably connected to the two second linkage mechanisms 313. The first movable shaft 3011, the second movable shaft 3012, and the third movable shaft 3013 are arranged in parallel to each other so that the whole of the second linkage mechanism 313 can deform radially in the slide block 11 under the action of the second power device 314.

[0055] Specifically, the second linkage mechanism 313 includes a first connecting rod 3131, a second connecting rod 3132, a third connecting rod 3133, and a fourth connecting rod 3134. One end of the first connecting rod 3131 is rotatably connected to the first support base 311. The other end of the first connecting rod 3131 and one end of the fourth connecting rod 3134 are rotatably connected to the second movable shaft 3012. The other end of the fourth connecting rod 3134 is rotatably connected to the middle of the third connecting rod 3133. One end of the second connecting rod 3132 is rotatably connected to the first movable shaft 3011. The other end of the second connecting rod 3132 is rotatably connected to one end of the third connecting rod 3133. The other end of the third connecting rod 3133 is rotatably connected to the third movable shaft 3013. The second linkage mechanism 313 has a simple structure, which can save materials and reduce the overall weight of the crawling component 32, thereby reducing the energy consumption generated by the crawling component 32 overcoming its own gravity.

[0056] In application, the second power device 314 can be a linear actuator, a cylinder, a hydraulic cylinder, or a lead screw and nut mechanism. The output end of the second power device 314 is connected to a second drive shaft 316. The two ends of the second drive shaft 316 are respectively rotatably connected to two first connecting rods 3131 so that the two second linkage mechanisms 313 can move synchronously.

[0057] In one embodiment, please refer to [the relevant documentation / reference]. Figures 5 to 7 The second displacement assembly 31 also includes a second buffer 315, which is used to brake the relative movement between the second support 312 and the second linkage mechanism 313.

[0058] In application, the second support base 312 is rotatably connected to the second brake shaft 317, which is rotatably connected to the crawling component 32. The second brake shaft 317 is arranged parallel to the third movable shaft 3013 and is located at the end of the second support base 312 away from the first support base 311. The two opposite ends of the second buffer member 315 are respectively connected to the third movable shaft 3013 and the second brake shaft 317. The first movable groove 3001, the second movable groove 3002 and the third movable groove 3003 cooperate to generate multi-stage displacement between the first support base 311 and the second support base 312 to ensure the stability of the crawling component 32 during operation.

[0059] In applications, the second buffer 315 can be a gas spring or a damper.

[0060] Specifically, when the surface of the street lamp is uneven or the outer diameter of the street lamp gradually changes, the crawling component 32 will separate from the surface of the street lamp during operation, causing the crawling component 32 to be unable to continue to rise and fall. By driving the first movable shaft 3011 to slide in the first movable groove 3001 and the second movable shaft 3012 to slide in the second movable groove 3002, the second support seat 312 can generate a relatively large displacement, so that the crawling component 32 can be in close contact with the surface of the street lamp. Then, by the third movable shaft 3013 sliding in the third movable groove 3003, the second support seat 312 can continue to generate a relatively small displacement. There is relative movement between the second support seat 312 and the second linkage mechanism 313, and the second buffer 315 brakes the second support seat 312 to reduce the vibration generated by the crawling component 32 under inertia. After the adjustment effect of the second support seat 312, the crawling component 32 can adapt to the surface under different working conditions, thereby ensuring that the crawling component 32 can stably perform the rising and falling operation.

[0061] In application, a second clamping member 318 is also sleeved on the outer periphery of the second brake shaft 317. The second clamping member 318 is made of elastic material and is used to limit the horizontal movement between the second support 312 and the crawling component 32 to further ensure connection stability.

[0062] In one embodiment, please refer to [the relevant documentation / reference]. Figures 5 to 7 The crawling assembly 32 includes a third support base 321, a second drive device 323 fixedly connected to the third support base 321, and a plurality of crawling wheels 322 rotatably connected to the third support base 321. The output end of the second drive device 323 is connected to the plurality of crawling wheels 322 in a transmission connection.

[0063] In application, one side of the third support 321 is rotatably mounted on the second brake shaft 317, and the other side of the third support 321 is rotatably mounted with multiple rollers 324. The multiple rollers 324 correspond one-to-one with multiple crawling wheels 322. The crawling wheels 322 are sleeved on the outer circumference of the rollers 324. The ends of adjacent rollers 324 on the same side are connected by a driven transmission belt 325. The second drive device 323 includes a motor and a reducer. The output shaft of the motor is connected to the input hole of the reducer. The output shaft of the reducer, as the output end of the second drive device 323, is connected by a drive transmission belt 326 to the end of one of the multiple rollers 324. Through the synchronous rotation of the multiple crawling wheels 322, the crawling assembly 32 has stronger crawling power and stability.

[0064] In application, the third support 321 is also connected to a plurality of tensioning wheels 327 corresponding to a plurality of driven conveyor belts 325. Each tensioning wheel 327 is connected to the corresponding driven conveyor belt 325 for adjusting the tension of the driven conveyor belt 325, so as to make the transmission connection between the plurality of rollers 324 more stable.

[0065] In one embodiment, please refer to [the relevant documentation / reference]. Figures 8 to 9 The slide 11 has a ring-shaped structure and includes multiple guide rail assemblies 111 connected end to end. The ends of adjacent guide rail assemblies 111 are detachably connected.

[0066] In application, the guide rail assembly 111 has an arc-shaped structure, and the ends of adjacent guide rail assemblies 111 are connected by snap-fit ​​or bolts to facilitate the mounting of the slide 11 on streetlights with different outer diameters, thereby further improving the applicability of the cleaning mechanism.

[0067] In one embodiment, please refer to [the relevant documentation / reference]. Figures 8 to 9 The slider 12 has a bent block structure.
