DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0019] In order to solve the technical problem that the cleaning robot in the prior art is only fixed and hovered on the pole to be cleaned by climbing wheels, the pressure on the climbing wheels is too large, the climbing wheels are easily deformed after long-term use, and the cleaning robot cannot be stably fixed at the target position, the present invention provides a cleaning robot, which can realize the cleaning robot stably hovering on the pole to be cleaned, and the cleaning robot can stably clean the pole. The pole to be cleaned can be a cylindrical column such as a bridge pier.

[0020] See also Figure 1 , Figure 1 This is a structural schematic diagram of a cleaning robot in an embodiment of the present invention, the cleaning robot includes a first climbing component 1 and a second climbing component 2, the first climbing component 1 includes a first bracket 11 and a plurality of first telescopic members 12, the first bracket 11 is formed with a hollow first clamping hole 13, the plurality of first telescopic members 12 are arranged around the circumference of the first clamping hole 13, and can approach or move away from the center of the first clamping hole 13 when telescoping.

[0021] The second climbing component 2 includes a slide 24, a second bracket 21 and a plurality of second telescopic members 22. The slide 24 is connected to the first bracket 11. The second bracket 21 is slidably connected to the slide 24 and is formed with a hollow second clamping hole 23. The plurality of second telescopic members 22 are arranged around the circumference of the second clamping hole 23 and can move closer to or away from the center of the second clamping hole 23 when telescoping.

[0022] In this embodiment, the first climbing assembly 1 and the second climbing assembly 2 are two separate devices. When working, the two can slide up and down relative to each other to achieve climbing on the pole. When cleaning the pole, the first climbing assembly 1 and the second climbing assembly 2 are first sleeved on the pole to be cleaned through the first clamping hole 13 and the second clamping hole 23 respectively. The diameters of the first clamping hole 13 and the second clamping hole 23 are both larger than the diameter of the pole. Control multiple first telescopic members 12 and / or second telescopic members 22 to abut the pole so that the cleaning robot is fixed on the pole. When it is necessary to adjust the height of the cleaning robot on the pole, the first bracket 11 and the second bracket 21 can be controlled to slide up and down alternately through the slide 24, and multiple first telescopic members 12 and second telescopic members 22 alternately abut the pole. The present application uses multiple first telescopic members 12 and multiple second telescopic members 22 to abut the pole, which is obviously more stable, and the cleaning robot can stably clean the pole.

[0023] In one embodiment, see Figure 2The first telescopic member 12 and the second telescopic member 22 have the same structure, and both include a connected telescopic rod 121 and a gripping piece 122. The gripping piece 122 is in an arc shape with a convex side facing the telescopic rod 121. In this embodiment, the telescopic rod 121 is hydraulically controlled to achieve telescopic extension. When the telescopic rod 121 is extended, the telescopic rod 121 can drive the gripping piece 122 to move closer to the center of the first gripping hole 13 to abut against the rod. When the telescopic rod 121 is shortened, the telescopic rod 121 can drive the gripping piece 122 to move away from the center of the first gripping hole 13 to detach from the rod. Therefore, the first climbing component 1 can be fixed or separated on the rod by controlling the extension and retraction of multiple first telescopic members 12. Similarly, the second climbing component 2 can be fixed or separated on the rod by controlling the extension and retraction of multiple second telescopic members 22. In addition, the clamping piece 122 can be made of flexible materials with a large friction system such as rubber or silicone, so that the clamping piece 122 can maintain a stable connection with the pole when abutting the pole, and can also be fully attached to the surface of poles of different diameters through elastic deformation of the clamping piece 122.

[0024] In one embodiment, see Figure 2 The first climbing assembly 1 further includes a climbing auxiliary wheel 14, which is located in the first clamping hole 13 and can roll on the surface of the pole when the first bracket 11 is lifted or lowered along the pole. In this embodiment, when the first bracket 11 is lifted or lowered along the pole, the climbing auxiliary wheel 14 can roll on the surface of the pole to assist the first climbing assembly 1 to be lifted or lowered stably.

[0025] For further information, see Figure 2 The number of climbing auxiliary wheels 14 is multiple, and the multiple climbing auxiliary wheels 14 are arranged around the circumference of the first holding hole 13, and the multiple climbing auxiliary wheels 14 and the multiple first telescopic members 12 are arranged in a staggered manner. In this embodiment, by providing multiple climbing auxiliary wheels 14 and arranging the multiple climbing auxiliary wheels 14 around the circumference of the first holding hole 13, the multiple climbing auxiliary wheels 14 can be arranged around the circumference of the pole to abut against the pole, which helps to enhance the balance of the lifting of the first climbing assembly 1.

[0026] In one embodiment, see Figure 2The climbing auxiliary wheel 14 includes a telescopic slide bar 141 and a roller 142 connected to each other. The telescopic slide bar 141 can drive the roller 142 to approach or move away from the center of the first holding hole 13 when it is extended or retracted. In this embodiment, the telescopic slide bar 141 drives the roller 142 to approach or move away from the center of the first holding hole 13 by hydraulic means. When the first climbing assembly 1 needs to be raised or lowered, the telescopic slide bar 141 can be controlled to drive the roller 142 to move close to the center of the first holding hole 13 so that the roller 142 abuts against the outer wall of the pole. When the first climbing assembly 1 is raised or lowered, the roller 142 can roll up and down along the surface of the pole to guide the raising and lowering of the first climbing assembly 1.

[0027] Furthermore, the climbing auxiliary wheel 14 further includes a buffer spring (not shown in the figure), which is arranged between the telescopic slide bar 141 and the roller 142. When the roller 142 abuts against the pole, the roller 142 can drive the buffer spring to compress and accumulate elastic force through the reaction force, so that the roller 142 can closely abut against the pole and can play a buffering role on the telescopic slide bar 141.

[0028] In one embodiment, see Figure 2 The slide 24 includes a plurality of slide bars 241, which are fixedly arranged around the circumference of the first bracket 11, for example, by welding. The second bracket 21 is slidably connected to the plurality of slide bars 241. In this embodiment, a long strip of rack 242 is provided in each slide bar 241, and a driving gear 211 is provided at the portion where the second bracket 21 is connected to each slide bar 241, and the corresponding rack 242 is meshed through the driving gear 211. Each driving gear 211 is correspondingly connected to a motor, which can drive the driving gear 211 to rotate forward or reverse when receiving a control command.

[0029] When the first bracket 11 is fixed by abutting the rod through multiple first telescopic members 12, the multiple slide bars 241 remain fixed at this time. If the driving gear 211 is controlled by the motor to rotate forward, the driving gear 211 engages with the slide bar 241 to drive the second bracket 21 to approach the first bracket 11; when the driving gear 211 is reversed, the driving gear 211 engages with the slide bar 241 to drive the second bracket 21 away from the first bracket 11.

[0030] When the second bracket 21 is fixed against the pole by the plurality of second telescopic members 22, if the driving gear 211 is controlled by the motor to rotate forward, the driving gear 211 drives the sliding rod 241 to move by meshing with the sliding rod 241, and the first bracket 11 approaches the second bracket 21; when the driving gear 211 is reversed, the driving gear 211 drives the first bracket 11 away from the second bracket 21 by meshing with the sliding rod 241. Therefore, the height adjustment of the cleaning robot on the pole can be realized by alternately abutting the pole with the first telescopic member 12 and the second telescopic member 22, and controlling the motor to drive the driving gear 211 to rotate forward or reverse, so as to facilitate cleaning of various parts of the pole.

[0031] In one embodiment, see Figure 2 The first bracket 11 includes a fixed frame 111 and a movable frame 112. The movable frame 112 is rotatably connected to the fixed frame 111, and can drive its free end to connect or detach from the fixed frame 111 when rotating. When the free end of the movable frame 112 is connected to the fixed frame 111, the movable frame 112 and the fixed frame 111 are enclosed to form the above-mentioned first clamping hole 13. In this embodiment, when the first bracket 11 is inserted into the pole, the movable frame 112 can be rotated relative to the fixed frame 111 to open the first clamping hole 13, and the pole is inserted through the first clamping hole 13, and then the movable frame 112 is rotated relative to the fixed frame 111 to close the first clamping hole 13, thereby completing the connection between the first bracket 11 and the pole. Similarly, the second bracket 21 has the same structure as the first bracket 11, and is also connected to the pole in this way.

[0032] In one embodiment, see Figure 2 The first climbing assembly 1 further includes a hydraulic rod 15, which is arranged on the fixed frame 111 and connected to the movable frame 112. The hydraulic rod 15 can drive the movable frame 112 to rotate relative to the fixed frame 111 when reciprocating and retracting. In this embodiment, a first convex seat 113 is arranged on the outer side of the fixed frame 111, and a second convex seat 114 is arranged on the outer side of the movable frame 112. One end of the hydraulic rod 15 is rotatably connected to the first convex seat 113, and the other end is rotatably connected to the second convex seat 114. The structure is reasonably arranged and does not occupy the space of the first clamping hole 13. When the hydraulic rod 15 is shortened, it can drive the movable frame 112 to rotate and open the first clamping hole 13. When the hydraulic rod 15 is extended, it can drive the movable frame 112 to rotate and close the first clamping hole 13. The operation of the hydraulic rod 15 can be remotely controlled by a computer, and the operation is convenient.

[0033] In one embodiment, see Figure 2The first climbing assembly 1 further includes a locking tongue 16 and a locking buckle 17. The locking tongue 16 is arranged on the fixed frame 111, and the locking buckle 17 is arranged on the free end of the movable frame 112. When the free end of the movable frame 112 is connected to the fixed frame 111, the locking tongue 16 can be inserted into the locking buckle 17 to lock the movable frame 112. In this embodiment, when the free end of the movable frame 112 is connected to the fixed frame 111, the first clamping hole 13 is closed. At this time, the locking tongue 16 can be inserted into the locking buckle 17 to lock the movable frame 112 to prevent the movable frame 112 from rotating to open the first clamping hole 13. When the first bracket 11 is sleeved on the pole, the movable frame 112 can be locked by inserting the locking tongue 16 into the locking buckle 17 to avoid opening the first bracket 11 during the cleaning process of the pole.

[0034] It should be emphasized that the locking tongue 16 is disposed on the fixed frame 111, which can be understood as the locking tongue 16 being directly disposed on the fixed frame 111 or the locking tongue 16 being indirectly disposed on the fixed frame 111 through other components, for example Figure 1 The embodiment shown has two movable frames 112, which are rotatably connected to the two ends of the fixed frame 111, and two hydraulic rods 15, which are respectively arranged on both sides of the fixed frame 111 and respectively connected to the two movable frames 112. The two hydraulic rods 15 can drive the two movable frames 112 to rotate when telescoping to close or open the first clamping hole 113. In this embodiment, by providing two movable frames 112, when the first clamping hole 13 is opened, the entrance of the first clamping hole 13 is larger, and the rod can be more conveniently inserted, thereby improving the installation efficiency.

[0035] A locking tongue 16 is provided at the free end of one of the movable frames 112, and a locking buckle 17 is provided at the free end of the other movable frame 112. When the two movable frames 112 are rotated to connect the two free ends, the locking tongue 16 is inserted into the locking buckle 17 to lock the free ends of the two movable frames 112 and close the first clamping hole 13. It should be noted that the second climbing assembly 2 has the same structure as the first climbing assembly 1, and the second bracket 21 also has the same opening and closing structure and opening and closing method as the first bracket 11, so as to be connected or disconnected from the pole.

[0036] In one embodiment, see Figure 2The cleaning robot further comprises a cleaning assembly 3, which comprises a circular track 31, a water spray head 32 and a camera 33. The circular track 31 is arranged on the second bracket 21, and the water spray head 32 and the camera 33 are both slidably arranged on the circular track 31 and can rotate along the circular track 31. In the present embodiment, the circular track 31 is an open structure, which is formed by two arc tracks connected by rotation, and the two arc tracks are respectively connected to the fixed frame and the movable frame of the second bracket 21, so that when the fixed frame and the movable frame rotate to open the second holding hole 23, the two arc tracks can also be opened at the same time, and when the second holding hole 23 is closed, the two arc tracks can also be driven to sleeve the rod. As the water spray head 21 moves on the circular track 31, the water spray position of the rod can be adjusted, and the rod can be cleaned in all directions and thoroughly. The camera 33 is used to shoot the rod after cleaning to detect whether the rod is cleaned. If it is not cleaned, the water spray head 21 is controlled to continue to spray water on the rod for cleaning.

[0037] The circular track 31 has a chain, and the water sprinkler 32 and the camera 33 are both provided with corresponding motors and gears (not shown in the figure), and both are engaged with the chain through the gears. When the motor drives the gears to rotate, since the chain is fixed, the gears can drive the water sprinkler 32 and the camera 33 to reciprocate along the circular track 31 through the meshing reaction force.

[0038] A storage rack 25 is also provided at the bottom of the second bracket 21. The storage rack 25 is used to hang some other items, such as a water tank. The water tank is used to connect the water spray head 21 through a water pipe so that the water spray head 21 can obtain water in the water tank and spray water to clean the pole.

[0039] In order to better understand the present invention, the following Figures 1 to 4 The technical solution of the present invention is described in detail: The cleaning robot provided by the present invention has a first bracket 11 and a second bracket 21 which can be sleeved on a pole to be cleaned, such as a bridge pier, through a first clamping hole 13 and a second clamping hole 23. The second bracket 21 can be used to install a water spray head 32. The second bracket 21 can slide relative to the slide 24 to adjust the height of the water spray head 32, so that the water spray head 32 can spray water to clean multiple parts of the pole. When the cleaning robot needs to hover at a certain part of the pole, the multiple first telescopic members 12 can be controlled to be telescopic to approach the center of the first clamping hole 13, so that the multiple first telescopic members 12 abut against the pole. Similarly, the multiple second telescopic members 22 can be controlled to be telescopic to approach the center of the second clamping hole 23, so that the multiple second telescopic members 22 abut against the pole. Compared with the existing robot using climbing wheels to position on the pole, the present application uses multiple first telescopic members 12 and multiple second telescopic members 22 to abut against the pole, which is obviously more stable. The cleaning robot can stably clean the pole and can be used to clean the parts of the pole above the water surface and below the water surface adjacent to the water surface. When the cleaning robot cleans the underwater part of the pole, the water pressure of the water spray head 32 can be increased, and the underwater part of the pole can be sprayed with high-pressure water to remove the pollutants attached to the surface of the pole. Various components on the cleaning robot are components with waterproof function, so that the cleaning robot can be waterproof when operating underwater.

[0040] The specific implementation of the present invention described above does not constitute a limitation on the protection scope of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the protection scope of the claims of the present invention.
