Description

Technical Field

[0001] This utility model relates to the field of manhole cleaning technology, and in particular to a cleaning mechanism and cleaning device. Background Technology

[0002] To facilitate the inspection and maintenance of water supply and drainage systems in urban underground infrastructure, inspection wells are usually installed at the junctions of drainage pipes. However, these inspection wells can accumulate sediment over time, so they need to be cleaned regularly.

[0003] Existing technologies typically employ cleaning devices to clean the interior of inspection wells. The moving components of the cleaning mechanism in these devices are usually fixedly mounted on the bottom surface of a base and abut against the end face of the inspection well to drive the cleaning mechanism. Simultaneously, the auxiliary wheel assembly abuts against the outer wall of the inspection well to improve the stability of the cleaning mechanism's movement. However, when the cleaning device is applied to inspection wells of different sizes, the moving components, due to the limitations of their installation position, are prone to having a smaller gap between themselves and the auxiliary wheel assembly relative to the width of the inspection well's end face, resulting in reduced stability of the cleaning device's movement. Utility Model Content

[0004] The main purpose of this invention is to propose a cleaning mechanism that aims to solve the problem of poor motion stability in existing cleaning devices.

[0005] To solve the above problems, this utility model proposes a cleaning mechanism, comprising:

[0006] Base;

[0007] The motion assembly includes two sets of motion wheels, which are slidably disposed on the bottom surface of the base along the movement direction of the cleaning mechanism. The two sets of motion wheels are used to abut against the end face of the inspection well to drive the cleaning mechanism to move.

[0008] A cleaning assembly, comprising a first cleaning component and a second cleaning component, spaced apart from each other on the base; the first cleaning component is used to clean the end face of the inspection well, and the second cleaning component is used to clean the outer wall of the inspection well; and

[0009] An auxiliary wheel assembly, one end of which is mounted on the bottom surface of the base, and the other end of which is used to abut against the outer wall of the inspection well;

[0010] Both of the aforementioned motion wheel sets can slide in a direction perpendicular to the movement of the cleaning mechanism to adjust the horizontal distance between themselves and the auxiliary wheel assembly.

[0011] In one embodiment, the cleaning mechanism further includes two adjusting members and a mounting plate. The two adjusting members are installed at intervals on the bottom surface of the base along the movement direction of the cleaning mechanism, and an installation gap is formed between the two adjusting members and the base. The mounting plate extends along the movement direction of the cleaning mechanism and is disposed on the bottom surface of the base. The two sets of moving wheels are respectively installed at both ends of the mounting plate. One end of the mounting plate is slidably disposed in one of the installation gaps to drive the two sets of moving wheels to slide in a direction perpendicular to the movement of the cleaning mechanism, so as to adjust the horizontal distance between the two sets of moving wheels and the auxiliary wheel assembly.

[0012] In one embodiment, the cleaning mechanism further includes a fixing member, both of the adjusting members are provided with a plurality of first through holes along the direction perpendicular to the movement of the cleaning mechanism, and at least one second through hole is provided at both ends of the mounting plate in the length direction.

[0013] The mounting plate slides along the direction perpendicular to the movement of the cleaning mechanism to correspond the second through hole with a different first through hole, and the fixing member is sequentially threaded to the first through hole and the second through hole.

[0014] In one embodiment, the auxiliary wheel assembly includes a mounting component, a rotating component, an elastic tensioning component, and an auxiliary wheel set. One end of the mounting component is mounted on the base, and a connecting shaft is provided on one side of the mounting component. One side of the rotating component is movably connected to the connecting shaft. The elastic tensioning component is mounted on the connecting shaft, and its two extended ends are respectively connected to the rotating component and the mounting component. The auxiliary wheel set is connected to the other end of the rotating component and is used to abut against the outer wall of the inspection well. The rotating component can swing relative to the mounting component to drive the auxiliary wheel set to adjust the distance between it and the outer wall of the inspection well.

[0015] In one embodiment, the auxiliary wheel assembly includes a mounting rod and an auxiliary wheel, one end of the mounting rod being detachably connected to the other end of the rotating component, and the other end being inserted into the auxiliary wheel;

[0016] And / or, the cleaning mechanism includes at least two of the auxiliary wheel assemblies, which are spaced apart and connected to the base along the direction of movement of the cleaning mechanism.

[0017] In one embodiment, a side plate is vertically provided on the inner sidewall of the inspection well end face;

[0018] The cleaning assembly also includes two third cleaning assemblies, which are spaced apart from each other on the base. One of the third cleaning assemblies abuts against one side of the inspection well side plate to clean both sides of the inspection well side plate.

[0019] In one embodiment, the cleaning mechanism further includes a guide plate, which is mounted on the base and its surface abuts against one side of the back of the inspection well side plate.

[0020] In one embodiment, the cleaning mechanism further includes two guide rails, which are spaced apart on the bottom surface of the base. The guide plate includes a plate body and two mounting seats. One end of one mounting seat is connected to one end of the plate body in the length direction, and the other end is slidably mounted on one of the guide rails.

[0021] In one embodiment, the cleaning mechanism further includes two anti-collision members, which are spaced apart on both ends of the base along the movement direction of the cleaning mechanism.

[0022] This utility model also proposes a cleaning device, including a device body and a cleaning mechanism, wherein the cleaning mechanism is as described above, and the device body is installed on the end of the base away from the moving component.

[0023] This utility model proposes a cleaning mechanism, including a base, a motion component, a cleaning component, and an auxiliary wheel assembly. The motion component includes two sets of motion wheels, which are slidably mounted on the bottom surface of the base along the movement direction of the cleaning mechanism to drive its movement. One end of the auxiliary wheel assembly is mounted on the bottom surface of the base, and the other end is used to abut against the outer wall of the inspection well to improve the movement stability of the cleaning mechanism. When the cleaning mechanism is applied to an inspection well with a large end face width, the motion wheels can be slid outward relative to the auxiliary wheel assembly on the base to increase the horizontal distance between them. In this case, the motion component and the auxiliary wheel assembly can distribute the weight of the cleaning mechanism more evenly, ensuring that the cleaning mechanism can move stably. Conversely, when the cleaning mechanism is applied to an inspection well with a small end face width, the motion wheels can be slid inward relative to the auxiliary wheel assembly on the base to ensure that the cleaning mechanism can always move stably, thereby improving the movement stability of the cleaning mechanism.

If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0037] Existing technologies typically employ cleaning devices to clean the interior of inspection wells. The moving components of the cleaning mechanism in these devices are usually fixedly mounted on the bottom surface of a base and abut against the end face of the inspection well to drive the cleaning mechanism. Simultaneously, the auxiliary wheel assembly abuts against the outer wall of the inspection well to improve the stability of the cleaning mechanism's movement. However, when the cleaning device is applied to inspection wells of different sizes, the moving components, due to the limitations of their installation position, are prone to having a smaller gap between themselves and the auxiliary wheel assembly relative to the width of the inspection well's end face, resulting in reduced stability of the cleaning device's movement.

[0038] To address the aforementioned problems, this utility model proposes a cleaning mechanism that aims to solve the issue of poor motion stability in existing cleaning devices.

[0039] like Figures 1 to 3 and Figure 5 In one embodiment, the cleaning mechanism 100 includes a base 10, a motion component 20, a cleaning component 40, and an auxiliary wheel assembly 50. The motion component 20 includes two sets of motion wheels 21, which are slidably disposed on the bottom surface of the base 10 along the movement direction of the cleaning mechanism 100. The two sets of motion wheels 21 are used to abut against the end face 300 of the inspection well to drive the cleaning mechanism 100 to move. The cleaning component 40 includes a first cleaning component 41 and a second cleaning component 42, which are spaced apart from each other on the base 10. The first cleaning component 41 is used to clean the end face 300 of the inspection well, and the second cleaning component 42 is used to clean the outer wall 400 of the inspection well. One end of the auxiliary wheel assembly 50 is mounted on the bottom surface of the base 10, and the other end is used to abut against the outer wall 400 of the inspection well.

[0040] In this embodiment, the base 10 serves as the fundamental support structure for the entire cleaning mechanism 100, and its material can be stainless steel or aluminum alloy, etc. The base 10 provides a platform for the installation and fixation of other components, ensuring the stability and integrity of the entire cleaning mechanism 100 during operation. The motion wheel assembly 21 mainly includes a transmission rod 211, a drive motor (not shown), and multiple wheel hubs 212. One end of the transmission rod 211 is slidably connected to the bottom surface of the base 10. The connection method can be a threaded connection, which ensures installation stability and facilitates changing the relative position of the motion wheel assembly 21 and the base 10. Multiple wheel hubs 212 are arranged side by side at intervals on both sides of the other end of the transmission rod 211. The specific type of wheel hub 212 is not limited here. For example, when the end face 300 of the inspection well is horizontal, multiple wheel hubs 212 can be common cylindrical wheel hubs 212. When the outer side of the end face 300 of the inspection well has a rounded chamfer, the wheel hub 212 near the rounded chamfer can be replaced with a frustum-shaped wheel hub 212 to ensure that the wheel hub 212 can fit tightly with the rounded chamfer and improve the motion stability of the cleaning mechanism 100. The drive motor is located inside the transmission rod 211 and drives the hub 212 so that the hub 212 can rotate relative to the transmission rod 211, thereby driving the entire cleaning mechanism 100 to move.

[0041] The first cleaning component 41 is a rotary cleaning brush driven by a motor. The bristles of the cleaning brush are made of high-strength nylon material with good cleaning ability, and their length and hardness are specially designed to effectively remove dirt and debris from the end face 300 of the inspection well. The second cleaning component 42 is a spiral rotary cleaning brush, also driven by a motor, used to remove dirt from the outer wall 400 of the inspection well. One end of the auxiliary wheel assembly 50 is detachably connected to the base 10, and the wheel at the other end is used to abut against the outer wall 400 of the inspection well. During the movement of the cleaning mechanism 100, the auxiliary wheel assembly 50 can play a supporting and guiding role, preventing the cleaning mechanism 100 from shifting or shaking inside the inspection well.

[0042] When the cleaning mechanism 100 proposed in this utility model is applied to a manhole with a large end face width, in order to enable the moving wheel assembly 21 and the auxiliary wheel assembly 50 to more evenly distribute the weight of the cleaning mechanism 100, one end of the transmission rod 211 can be threadedly connected to the base 10 near the outer side of the manhole end face 300. This increases the horizontal distance between the moving wheel assembly 21 and the auxiliary wheel assembly 50, allowing the moving assembly 20 and the auxiliary wheel assembly 50 to distribute the weight of the cleaning mechanism 100 more evenly, ensuring stable movement of the cleaning mechanism 100. The reverse is also true, and will not be elaborated further here.

[0043] In other embodiments, when the outer side of the end face 300 of the inspection well has a rounded chamfer, the frustum-shaped hub 212 can always be tightly fitted with the rounded chamfer by changing the relative position of the moving wheel assembly 21 and the base 10, thereby improving the movement stability of the cleaning mechanism 100.

[0044] like Figures 1 to 3 and Figure 5 In one embodiment, the cleaning mechanism 100 further includes two adjusting members 30 and a mounting plate 60. The two adjusting members 30 are installed at intervals on the bottom surface of the base 10 along the movement direction of the cleaning mechanism 100, and an installation gap is formed between the two adjusting members 30 and the base 10. The mounting plate 60 extends along the movement direction of the cleaning mechanism 100 and is disposed on the bottom surface of the base 10. Two sets of moving wheels 21 are respectively installed at both ends of the mounting plate 60. One end of the mounting plate 60 is slidably disposed in an installation gap to drive the two sets of moving wheels 21 to slide along the direction perpendicular to the movement direction of the cleaning mechanism 100.

[0045] In this embodiment, the adjusting member 30 is a metal plate with an L-shaped end face. Its upright plate 31 is vertically connected to the bottom surface of the base 10, ensuring that the adjusting member 30 is installed on the base 10 as a whole. When the upright plate 31 is vertically connected to the bottom surface of the base 10, an installation gap is formed between the base plate 32 and the base 10. The mounting plate 60 is a metal plate. The mounting plate 60 connects the two motion wheel sets 21 into a whole. Compared with directly installing each motion wheel set 21 separately on the bottom surface of the base 10, it greatly enhances the structural stability of the motion component 20. During the movement of the cleaning mechanism 100, especially when the road surface inside the inspection well is uneven or encounters great resistance, the mounting plate 60 can effectively distribute the force, avoid damage to a single motion wheel set 21 due to excessive pressure, and extend the service life of the motion component 20.

[0046] The connection between the mounting plate 60 and the adjusting member 30 can be either snap-fit ​​or threaded. The length of the adjusting member 30 is greater than the width of the mounting plate 60. By threading or snapping the two ends of the mounting plate 60 to different positions of the two adjusting members 30, the distance between the two moving wheel sets 21 and the auxiliary wheel assembly 50 can be adjusted. Since the mounting plate 60 slides as a whole, the two moving wheel sets 21 move the same distance, ensuring the symmetry and accuracy of the adjustment of the moving wheel sets 21, and further improving the movement stability of the cleaning mechanism 100.

[0047] like Figures 1 to 3 and Figure 5 In one embodiment, the cleaning mechanism 100 further includes a fixing member, both adjusting members 30 are provided with a plurality of first through holes along the direction perpendicular to the movement of the cleaning mechanism 100, and at least one second through hole is provided at both ends of the mounting plate 60 in the length direction.

[0048] In this embodiment, the fixing member is a bolt, and both the first and second through holes are threaded holes. As described in the previous embodiment, when the vertical plate 31 of the adjusting member 30 is vertically connected to the bottom surface of the base 10, an installation gap is formed between the base plate 32 and the base 10. At this time, the base plate 32 has multiple first through holes spaced apart in the length direction, and at least one second through hole is opened at both ends of the mounting plate 60 in the length direction. By using the fixing member to thread the second through holes to different first through holes, the mounting plate 60 can slide along the length direction of the base plate 32 within the installation gap, that is, the motion wheel assembly 21 can move along the movement direction of the vertical cleaning mechanism 100. This achieves precise adjustment of the horizontal distance between the motion wheel assembly 21 and the auxiliary wheel assembly 50.

[0049] like Figures 1 to 3 and Figure 6 In one embodiment, the auxiliary wheel assembly 50 includes a mounting member 51, a rotating member 52, an elastic tensioning member 53, and an auxiliary wheel set 54. One end of the mounting member 51 is mounted on the base 10, and a connecting shaft 55 is provided on one side of the mounting member 51. One side of the rotating member 52 is movably connected to the connecting shaft 55. The elastic tensioning member 53 is mounted on the connecting shaft 55, and the two extended ends of the elastic tensioning member 53 are respectively connected to the rotating member 52 and the mounting member 51. The auxiliary wheel set 54 is connected to the other end of the rotating member 52 and is used to abut against the outer wall 400 of the inspection well. The tensioning member can swing relative to the mounting member 51 to drive the auxiliary wheel set 54 to adjust the distance between it and the outer wall 400 of the inspection well.

[0050] In this embodiment, the mounting component 51 is a metal connector to ensure a stable connection between the auxiliary wheel assembly 50 and the base 10. The connection method can be a threaded connection or a snap-fit ​​connection. While ensuring a stable connection between the auxiliary wheel assembly 50 and the base 10, it is easy to replace and disassemble, thus improving the practicality of the auxiliary wheel assembly 50. One end of the rotating component 52 is movably connected to the connecting shaft 55, allowing it to swing vertically relative to the base 10. The other end of the rotating component 52 is equipped with an auxiliary wheel assembly 54, which provides support and guidance, improving the motion stability of the cleaning mechanism 100. The elastic tensioning component 53 consists of two torsion springs symmetrically arranged at both ends of the connecting shaft 55. Each torsion spring has two extended ends connected to the mounting component 51 and the rotating component 52, respectively, so that when the rotating component 52 swings relative to the base 10, the torsion springs will also undergo torsional deformation. Specifically, when the auxiliary wheel assembly 50 is subjected to an external force from the outer wall 400 of the inspection well, it will push the rotating component 52 to swing toward the inner side of the base 10. At this time, the torsion spring will be torsioned and store elastic potential energy. When the external force disappears, the torsion spring will rely on the stored elastic potential energy to drive the rotating component 52 back to its initial position. The torsion spring provides an automatic reset function for the rotating component 52. When the cleaning mechanism 100 is located in a small inspection well, the torsion spring will use its own elastic force to keep the auxiliary wheel assembly 54 in proper contact with the outer wall 400 of the inspection well. When the cleaning mechanism 100 needs to be placed in a larger inspection well, the torsion spring can quickly pull the auxiliary wheel assembly 54 back to the appropriate position through its own restoring force, realizing the adaptive adjustment of the auxiliary wheel assembly 50, so that the auxiliary wheel assembly 54 can always be in contact with the outer wall 400 of the inspection well, further improving the movement stability of the cleaning device.

[0051] like Figures 1 to 3 and Figure 6 In one embodiment, the auxiliary wheel assembly 54 includes a mounting rod 541 and an auxiliary wheel 542. One end of the mounting rod 541 is detachably connected to the other end of the rotating member 52, and the other end is inserted into the auxiliary wheel 542.

[0052] In this embodiment, the auxiliary wheel 542 is used to directly contact and roll against the outer wall 400 of the inspection well. Its material is generally chosen to be wear-resistant and elastic, such as rubber or polyurethane, to reduce damage to the outer wall 400 of the inspection well and to provide better adhesion, ensuring the stable operation of the cleaning mechanism 100. The mounting rod 541 serves to connect the auxiliary wheel 542 and the rotating component 52. One end of the mounting rod 541 is detachably connected to the other end of the rotating component 52. This detachable connection can be a bolt connection, a snap-fit ​​connection, etc., facilitating the disassembly and replacement of the auxiliary wheel assembly 54 when needed. The other end of the mounting rod 541 is inserted into the auxiliary wheel 542, and the two can be connected through a slot or shaft hole mating structure, ensuring that the mounting rod 541 is securely connected to the auxiliary wheel 542, ensuring effective force transmission during movement and driving the auxiliary wheel 542 to rotate normally. The design of the auxiliary wheel assembly 54 allows maintenance personnel to easily replace the auxiliary wheel 542 by simply separating the rotating part 52 from the mounting rod 541 when the auxiliary wheel 542 is worn or damaged, without having to disassemble the entire motion mechanism extensively. This also allows the auxiliary wheel assembly 54 to be flexibly adjusted according to different cleaning tasks and pool wall conditions, thus improving the versatility and applicability of the cleaning mechanism 100.

[0053] like Figures 1 to 3 and Figure 6 In one embodiment, the cleaning mechanism 100 includes at least two auxiliary wheel assemblies 50, which are spaced apart from each other on the base 10 along the movement direction of the cleaning mechanism 100.

[0054] In this embodiment, the cleaning mechanism 100 includes multiple auxiliary wheel assemblies 50, which are spaced apart on the base 10 along the movement direction of the cleaning mechanism 100. The arrangement of multiple auxiliary wheel assemblies 50 enhances the movement stability of the cleaning mechanism 100 in complex environments. When one of the auxiliary wheel assemblies 50 encounters a special situation (such as a protrusion or depression) on the outer wall 400 of the inspection well pool, the other auxiliary wheel assemblies 50 can still maintain normal contact with the outer wall 400 of the pool, continuing to provide stable support and guidance for the cleaning mechanism 100. This ensures that the cleaning mechanism 100 will not affect its overall operation due to local instability, further improving the working stability of the cleaning mechanism 100 in complex environments.

[0055] like Figures 1 to 3 and Figure 5 In one embodiment, a side plate 500 is vertically arranged on the inner sidewall of the inspection well end face 300. The cleaning component 40 also includes two third cleaning components 43, which are spaced apart from each other on the base 10. One third cleaning component 43 abuts against one side of the inspection well side plate 500 to clean both sides of the inspection well side plate 500.

[0056] In this embodiment, the side plate 500 is a vertical plate-like structure set on the inner sidewall of the inspection well end face 300, generally made of sturdy materials such as concrete or metal. In practical applications, the inspection well side plate 500 may be set to separate different areas, enhance structural stability, or for other functional requirements. In this embodiment, the side plate 500 is installed on the inner circumference of the inspection well end face 300 and is perpendicular to the end face 300. The third cleaning component 43 includes a cleaning brush, a drive motor, and a mounting bracket. One end of the mounting bracket is connected to the bottom surface of the base 10, and the other end is connected to the cleaning brush. The drive motor is installed on the base 10 and can drive the mounting bracket and the cleaning brush to rotate through gear meshing or belt drive. The cleaning brush is a cylindrical cleaning brush, and its material can be high-strength nylon, so that the cleaning brush can effectively penetrate into the fine gaps and depressions on the surface of the inspection well side plate 500 for cleaning. Two third cleaning components 43 are spaced apart on the base 10. The spacing is designed according to the width of the inspection well side plate 500 to ensure that both sides of the inspection well side plate 500 can be fully covered and cleaned.

[0057] like Figures 1 to 5 In one embodiment, the cleaning mechanism 100 further includes a guide plate 70, which is mounted on the base 10 and the surface of the guide plate 70 abuts against one side of the inspection well side plate 500.

[0058] In this embodiment, the guide plate 70 is made of a high-strength, wear-resistant material, such as stainless steel or hard plastic, to ensure that the guide plate 70 is not easily deformed during long-term use and has good wear resistance. The shape of the guide plate 70 is designed according to the structure of the inspection well side plate 500 and the cleaning mechanism 100. The guide plate 70 can be installed on the base 10 by bolts or welding to ensure that the guide plate 70 will not loosen or shift during the operation of the cleaning mechanism 100. When the cleaning mechanism 100 is working, the surface of the guide plate 70 is in close contact with the side of the inspection well side plate 500 away from the cleaning mechanism 100, providing guidance for the movement of the cleaning mechanism 100 in the inspection well. Specifically, the guide plate 70 can guide the cleaning mechanism 100 to move accurately along the direction of the inspection well side plate 500. When the third cleaning component 43 cleans the inspection well side plate 500, due to the guiding effect of the guide plate 70, the cleaning brush can always maintain a suitable contact angle and pressure with the surface of the side plate 500, avoiding cleaning dead corners or over-cleaning, thereby improving the cleaning accuracy and ensuring that every part of the inspection well side plate 500 is effectively cleaned, thus improving the overall cleaning quality.

[0059] like Figures 1 to 5In one embodiment, the cleaning mechanism 100 further includes two guide rails 80. The guide plate 70 includes a plate body 71 and two mounting seats 72. One end of a mounting seat 72 is connected to one end of the plate body 71 in the length direction, and the other end is slidably mounted on a guide rail 80.

[0060] In this embodiment, two guide rails 80 are installed parallel to the base 10 along the movement direction of the cleaning mechanism 100 and are fixed by bolts or welding to ensure that the guide rails 80 will not be displaced during the operation of the cleaning mechanism 100. At the same time, both guide rails 80 are provided with sliding grooves. Both mounting seats 72 are block structures, one end of which is fixedly connected to one end of the panel body in the length direction. The connection method can be threaded connection, which ensures stable installation and facilitates disassembly. The other end has a slider that matches the sliding groove so that it can slide smoothly relative to the slide rail, thereby driving the panel body 71 to slide. The cooperation between the guide rail 80 and the mounting base 72 allows the plate body 71 to adjust the distance between itself and the inspection well side plate 500, enabling the plate body 71 to abut against side plates 500 of different widths. This improves the versatility of the guide plate 70, making it suitable for inspection wells of different sizes. It ensures that the third cleaning component 43 maintains a suitable contact angle and pressure with the surface of the side plate 500 in inspection wells of different sizes. Furthermore, the modular design of the guide plate 70 or guide rail 80 facilitates maintenance and replacement when they become worn or damaged. During maintenance, only the damaged guide plate 70 or guide rail 80 needs to be disassembled individually for repair or replacement, eliminating the need for large-scale disassembly of the entire cleaning mechanism 100, thus saving maintenance time and costs.

[0061] like Figures 1 to 3 In one embodiment, the cleaning mechanism 100 further includes two anti-collision members 90, which are spaced apart on the two end faces 300 of the base 10 along the movement direction of the cleaning mechanism 100.

[0062] In this embodiment, the anti-collision component 90 includes two elastic buffer rods 91 and one anti-collision rod 92. One end of the two elastic buffer rods 91 is connected to the bottom surface of the base 10 at a distance, and the other end of the two elastic buffer rods 91 is connected to the anti-collision rod 92. When the cleaning mechanism 100 moves inside the inspection well, it may collide with the internal structure or obstacles of the inspection well for various reasons. At this time, the anti-collision rod 92 can first contact the obstacle and absorb the impact force through the elastic buffer rods 91, thereby extending the service life of the cleaning mechanism 100 and reducing equipment maintenance costs.
