DETAILED DESCRIPTION

[0023] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Reference Figures 1 to 3

[0025] The multifunctional pipeline cleaning device comprises a main body 1, a cleaning mechanism (not shown in the figure) and a walking mechanism arranged at the front and rear ends of the main body 1. A traction member 11 for traction of the cleaning mechanism is arranged in the main body 1. The cleaning mechanism is connected to the traction member 11 so that the cleaning mechanism is driven to move and clean in the pipeline through the traction member 11. Of course, the cleaning mechanism in this embodiment can also adopt a mechanism with other functions, as long as the mechanism is connected to the traction member 11, and the cleaning mechanism in this embodiment is a cleaning mechanism conventionally used in the market, which will not be described in detail here.

[0026] Each walking mechanism includes a plurality of driving wheels 21 evenly distributed around one end away from the main body 1. Each driving wheel 21 can be radially retracted or expanded along the axis of the main body 1, and the surface of each driving wheel 21 abuts against the inner wall of the pipe (not shown in the figure). In this embodiment, the walking mechanism uses four driving wheels 21, but of course it is not limited to four. The specific number can be set according to actual conditions, which will not be described in detail here.

[0027] For the convenience of description, the following only describes the continuous relationship between a single driving wheel 21 and the main body 1, and the connection relationships between the other driving wheels 21 and the main body 1 are the same, which will not be described in detail here.

[0028] A connecting member 4 for connecting the driving wheel 21 and the main body 1 is provided between the two. One end of the connecting member 4 is hinged to the corresponding driving wheel 21 , and the other end is rotationally connected to the main body 1 through a rotating mechanism 3 .

[0029] The rotating mechanism 3 includes a pin shaft 31 and a torsion spring 32 sleeved on the outside of the pin shaft 31. The two end arms of the torsion spring 32 are respectively in contact with the main body 1 and the connecting member 4, that is, the connecting member 4 provided with the driving wheel 21 is in an expanded state under the action of the torsion spring 32; when the utility model is arranged in a pipeline and the inner diameter of the pipeline is small, the connecting member 4 provided with the driving wheel 21 is in a retracted state under the action of the torsion spring 32.

[0030] Furthermore, two connecting plates 43 are extended from one end of the connecting member 4 close to the main body 1 in a direction away from the driving wheel 21 . The two connecting plates 43 are symmetrically arranged on the connecting member 4 , and the torsion spring 32 is arranged between the two connecting plates 43 .

[0031] Both ends of the main body 1 are provided with grooves 12 for placing the driving wheel 21, and the groove 12 includes a first side wall 121 for limiting the rotation of the connecting member 4 along the axial direction of the main body 1, a second side wall 122 for limiting the rotation of the connecting member 4 along the axial direction away from the main body 1, and two third side walls 123 for connecting the first side wall 121 and the second side wall 122. The first side wall 121, the second side wall 122 and the two third side walls 123 form a groove 12 for placing two connecting plates 43 and the rotating mechanism 3, and the two connecting plates 43 and the two third side walls 123 are connected by a pin shaft 31.

[0032] Preferably, the second side wall 122 is provided with a first connection groove 41 for one end arm of the torsion spring 32 to be relatively fixedly connected, and the end of the connecting member 4 close to the main body 1 is provided with a second connection groove 42 for the other end arm of the torsion spring 32 to be relatively fixedly connected, and the connecting member 4 is in an unfolded state in the axial direction away from the main body 1 under the action of the torsion spring 32. The driving wheel 21 is unfolded under the action of the torsion spring 32, or the driving wheel 21 is folded inwardly under the action of being squeezed by the inner wall of the pipe.

[0033] In the present invention, when each driving wheel 21 is in an expanded state, the torsion force of the torsion spring 32 is 0, and when each driving wheel 21 is in a folded state, the torsion spring 32 is squeezed. Take the folded state to the expanded state as an example for explanation, when the inner diameter of the pipeline increases from small to large, the driving wheel 21 originally squeezed by the inner wall of the pipeline moves into a wider pipeline, at this time, the driving wheel 21 is not subjected to the external force of the inner wall of the pipeline, and the restoring force of the torsion spring 32 drives each driving wheel 21 to expand outward, so that each driving wheel 21 maintains the abutment with the inner wall of the pipeline; the advantage of the present invention is that: through the above structure, the shapes of each driving wheel 21 can be different when the pipeline is shaped or bent.

[0034] Preferably, a driving mechanism for driving the corresponding driving wheel 21 to rotate is also provided between each driving wheel 21 and the connecting member 4, and the driving mechanism includes a motor fixing frame 51 and a reduction motor (not shown in the figure) arranged on the motor fixing frame 51, and the output shaft of the reduction motor is connected to the shaft of the driving wheel 21 to drive the driving wheel 21 to rotate forward / reverse.

[0035] Preferably, a through slot (not shown) is provided at one end of the connecting member 4 close to the driving wheel 21 for placing the motor fixing frame 51, and the motor fixing frame 51 is arranged in the through slot and is buckled and connected to the connecting member 4. In order to facilitate the replacement of the reduction motor or the driving wheel 21

[0036] Preferably, a rubber pad is provided on the end surface of the driving wheel 21. The rubber pad can drive the wheel 21 to slide relative to the inner wall of the pipe on one hand; on the other hand, by providing a relatively thick rubber pad at the end of the driving wheel 21, when each driving wheel 21 is running on the curved pipe, the driving wheel 21 on the side that is in contact with the pipe wall can also adaptively expand and contract the compression amount of the rubber pad through the softness of the rubber pad itself, so as to facilitate better steering of the device.

[0037] Preferably, this embodiment further includes a control mechanism and a detection mechanism. The detection mechanism is arranged at one or both ends of the walking mechanism 1, and the detection module includes a camera and a fill light (not shown in the figure), the camera is a non-spherical lens camera for collecting high-definition video data, and the fill light is a ring LED light arranged around the camera. In this arrangement, the ring LED light provides a high-brightness light source, which can ensure that the brightness of the video collection area in the pipeline is greater than the visual inspection requirement, so that the camera 3 can collect clear image information.

[0038] The control mechanism is respectively connected to the camera and the reduction motor for communication. The control mechanism is used to control the reduction motor to rotate so that the walking mechanism moves in the pipeline, and to start the detection mechanism to detect the pipeline.

[0039] Further, the control mechanism includes an image transmission module, an image processing module, an alarm module, a data transmission module, a motion information acquisition module and an analysis and positioning module. The image transmission module is connected to the camera 3 and is used to receive the image data captured by the camera 3. The image processing module determines whether the inner wall of the pipeline is damaged according to the image data. The analysis and positioning module is connected to the image data processing module and is used to locate and analyze the position where the pipeline is damaged when the pipeline is detected to be damaged. Specifically, the camera 3 takes real-time photos of the interior of the pipeline and transmits the pipeline image to the image transmission module. The image transmission module then transmits the pipeline image to the image processing module. The image processing module processes and analyzes the pipeline image to determine whether the pipeline in the image is damaged. The motion information acquisition module is used to collect the motion state of the detection device in real time. Specifically, in order to facilitate the detection personnel to understand the location of the damage, when the image processing module detects that the pipeline is damaged, the analysis and positioning module locates and analyzes the damaged position of the inner wall of the pipeline. The alarm module and the data transmission module are both connected to the analysis and positioning module and are used to issue an alarm message when the pipeline is detected to be damaged. Specifically, in order to promptly inform the inspection personnel of the damage status of the pipeline, when damage to the pipeline is detected, the image processing module sends damage information to the positioning analysis module. After the positioning analysis module analyzes the position of the pipeline detection module, the damage information is sent to the alarm module. After receiving the damage information, the alarm module issues an alarm message. At the same time, the positioning analysis module sends the position information and damage information to the data transmission module. The data transmission module is wirelessly connected to the external device in advance, and the position information and damage information are sent to the external device by wireless transmission, so that the inspection personnel can promptly know the damage status and damage location of the pipeline.

[0040] By adopting the above-mentioned design scheme, the beneficial effect of the utility model is as follows: the torsion spring 32 is respectively in contact with the main body 1 and the driving wheel 21, and the driving wheel 21 is in an expanded state under the action of the torsion spring 32, so that when the diameter of the pipeline changes, the driving wheel 21 can be automatically retracted and expanded under the action of the elastic restoring force of the torsion spring 32, so that the driving wheel 21 and the inner wall of the pipeline maintain a large pressure, and there is an appropriate friction force between the driving wheel 21 and the inner wall of the pipeline, so that the driving wheel 21 maintains a better driving force, and the size of the device is reduced, which is convenient for collection and carrying.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
