When the movable pipeline obstacle clearing mechanism moves inside the pipeline, the obstacle breaking component can break the obstacles. Moreover, the bottom of the obstacle breaking component is higher than the bottom of the driving wheels, which can prevent the obstacle breaking component from hindering the normal movement of the movable pipeline obstacle clearing mechanism. Specifically, when the movable pipeline obstacle clearing mechanism moves inside the pipeline, if the obstacle breaking element encounters an obstacle, first, the obstacle breaking element will abut against the obstacle, and then, as the movable pipeline obstacle clearing mechanism continues to move forward in the pipeline, the elastic element will be slowly stretched, and the stretched elastic element will exert a greater force on the obstacle breaking element, thereby increasing the force exerted by the obstacle breaking element on the obstacle and improving the obstacle breaking effect. In addition, as the movable pipeline obstacle clearing mechanism continues to move forward in the pipeline, relative to the main body, the front end of the obstacle breaking element will slowly tilt downward. In this way, the direction of the force exerted by the obstacle breaking element on the obstacle will slowly tilt downward. When the subsequent obstacle breaking element breaks the obstacle, the front end of the obstacle breaking element will gradually shovel downward, so that more obstacles can be broken.

Specifically, when the movable pipeline obstacle clearing mechanism moves inside the pipeline, if the obstacle breaking element encounters an obstacle, first, the obstacle breaking element will first abut against the obstacle. Then, as the movable pipeline obstacle clearing mechanism continues to move forward in the pipeline, the elastic member will be slowly stretched, and the stretched elastic member will exert a greater force on the obstacle breaking element, thereby increasing the force exerted by the obstacle breaking element on the obstacle and improving the obstacle breaking effect. In addition, as the movable pipeline obstacle clearing mechanism continues to move forward in the pipeline, relative to the main body, the front end of the obstacle breaking element will slowly tilt downward. In this way, the direction of the force exerted by the obstacle breaking element on the obstacle will slowly tilt downward.

[0031] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation of the present utility model.

[0032] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model. In addition, the features defined with "first", "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, unless otherwise stated, the meaning of "a plurality" is two or more.

[0033] In the description of the present utility model, it should be noted that unless otherwise clearly defined and limited, the terms "installation", "connection", "coupling" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0034] As Figure 1 shown, a movable pipeline obstacle clearing mechanism 110 provided by the present utility model can move inside the pipeline and clear the obstacles 10 inside the pipeline.

[0035] As Figures 1 to 3 shown, the movable pipeline obstacle clearing mechanism 110 includes a traveling body 111, a front camera 112, and a barrier breaking assembly 113.

[0036] The traveling body 111 includes a main body 1111 and driving wheels 1112 provided on the main body 1111. The bottom of the driving wheels 1112 is lower than the bottom of the main body 1111.

[0037] It can be understood that the main body 1111 is the main load-bearing structure, and the driving wheels 1112 can rotate to drive the entire movable pipeline obstacle clearing mechanism 110 to move.

[0038] It should be noted that the driving wheels 1112 can perform various actions such as moving forward, backward, and changing direction.

[0039] The front camera 112 is provided at the front end of the main body 1111 and can collect images in front of the movable pipeline obstacle clearing mechanism 110, and the images can be displayed on a display panel in communication connection with the front camera 112.

[0040] Furthermore, a rear camera 117 is also provided on the main body 1111. The rear camera 117 can collect images behind the movable pipeline obstacle clearing mechanism 110, and the images can also be displayed on a display panel that is communicatively connected to the front camera 112.

[0041] Even further, a thermal imaging detection module 116 is also provided on the main body 1111. The thermal imaging detection module 116 can also collect images and display the images on a display device.

[0042] Specifically, the front camera 112, the rear camera 117, and the thermal imaging detection module 116 can collect images simultaneously and be displayed on the display device at the same time. The three images can be displayed in multiple display modes according to the actual on-site requirements. For example, in a one-main-two-sub display mode, one of the three images can be placed in the center of the main screen for display, and the other two can be arranged in a small frame on one side of the interface. This mode is suitable for detailed observation of a certain perspective. In a two-main-one-sub display mode, two of the images can be placed side by side in the main screen for display, and the other image can be placed on one side of the interface. This mode is convenient for comparing the three images to further confirm suspected defects. Among them, the display device is provided with functions of screenshot, video recording, and recording. When a defective position is found, screenshots, video recordings, and relevant information are taken and recorded, such as the distance of the defective position inside the pipeline and the type of defect identified by the camera, for easy repair or comparison during re-inspection.

[0043] Combined with Figure 1 and Figure 2 , it should be noted that a protective tube 115 is provided at the top of the main body 1111. The thermal imaging detection module 116 is provided inside the front end of the protective tube 115, and the rear camera 117 is provided inside the rear end of the protective tube 115.

[0044] It can be understood that the protective tube 115 can protect the thermal imaging detection module 116 and the rear camera 117, reducing the risk of the thermal imaging detection module 116 and the rear camera 117 being damaged.

[0045] As Figure 3 shown, the obstacle breaking component 113 is provided at the bottom of the main body 1111, and the bottom of the obstacle breaking component 113 is higher than the bottom of the driving wheel 1112.

[0046] It can be understood that when the movable pipeline obstacle clearing mechanism 110 moves in the pipeline, the obstacle breaking component 113 can break through the obstacle 10, and the bottom of the obstacle breaking component 113 is higher than the bottom of the driving wheel 1112, which can prevent the obstacle breaking component 113 from hindering the normal movement of the movable pipeline obstacle clearing mechanism 110.

[0047] Combined with Figure 3 and Figure 4 , wherein, the obstacle-breaking component 113 includes an elastic member 1132 connected to the main body 1111 and an obstacle-breaking element 1131 connected to the elastic member 1132. The rear end of the obstacle-breaking element 1131 is rotatably connected to the main body 1111. The bottom end of the elastic member 1132 is connected to the obstacle-breaking element 1131, and the top end of the elastic member 1132 is connected to the main body 1111.

[0048] As Figure 5 shown, it can be understood that when the movable pipeline obstacle-clearing mechanism 110 moves in the pipeline, if the obstacle-breaking element 1131 encounters an obstacle 10, first of all, the obstacle-breaking element 1131 will first abut against the obstacle 10. Then, as the movable pipeline obstacle-clearing mechanism 110 continues to move forward in the pipeline, the elastic member 1132 will be slowly stretched. The stretched elastic member 1132 will exert a greater force on the obstacle-breaking element 1131, thereby increasing the force exerted by the obstacle-breaking element 1131 on the obstacle 10 and improving the obstacle-breaking effect. In addition, as the movable pipeline obstacle-clearing mechanism 110 continues to move forward in the pipeline, relative to the main body 1111, the front end of the obstacle-breaking element 1131 will slowly tilt downward. In this way, the direction of the force exerted by the obstacle-breaking element 1131 on the obstacle 10 will slowly tilt downward. When the obstacle-breaking element 1131 breaks the obstacle 10 subsequently, the front end of the obstacle-breaking element 1131 will gradually shovel downward, so that more of the obstacle 10 can be broken.

[0049] Combined with Figure 4 and Figure 5 , further, the obstacle-breaking element 1131 includes a connecting portion 11311 and an obstacle-breaking portion 11312 connected in front of the connecting portion 11311. The connecting portion 11311 is rotatably connected to the main body 1111; the elastic member 1132 is a spring. The bottom end of the spring is connected to the obstacle-breaking portion 11312, and the top end of the spring is connected to the main body 1111.

[0050] It should be noted that the connecting portion 11311 can be rotatably connected to the main body 1111 by means of a hinge.

[0051] Further, the front portion of the obstacle-breaking element 1131 gradually tilts downward in the direction from the rear to the front, and the front end of the obstacle-breaking element 1131 is a sharp-corner structure. That is, the obstacle-breaking portion 11312 gradually tilts downward in the direction from the rear to the front, and the front end of the obstacle-breaking portion 11312 is a sharp-corner structure. In this way, when the obstacle-breaking portion 11312 breaks the obstacle 10, the pressure on the obstacle 10 is greater, which is beneficial to improving the obstacle-breaking efficiency.

[0052] As Figure 5As shown, in some embodiments, a receiving cavity 11111 is provided at the bottom of the main body 1111. The barrier-breaking component 113 is connected to the main body 1111 in a liftable manner, and the barrier-breaking component 113 includes a working position and a storage position; when the barrier-breaking component 113 is in the storage position, the barrier-breaking component 113 is located in the receiving cavity 11111; when the barrier-breaking component 113 is in the working position, the barrier-breaking component 113 is located below the receiving cavity 11111.

[0053] It can be understood that by lifting and lowering the barrier-breaking component 113, the position of the barrier-breaking component 113 can be switched, so that the barrier-breaking component 113 reaches the working position or the storage position. When the barrier-breaking component 113 is not required to break the obstacle 10 in the pipeline, for example, when the movable pipeline obstacle-clearing mechanism 110 travels on the ground, the barrier-breaking component 113 can be lifted to the storage position to prevent the barrier-breaking component 113 from colliding with the sundries on the ground. When the barrier-breaking component 113 is needed, the barrier-breaking component 113 can be lowered to the working position so that the barrier-breaking component 113 can break the obstacle 10 in the pipeline.

[0054] Specifically, the barrier-breaking component 113 further includes an intermediate connecting plate 1133. The rear end of the barrier-breaking element 1131 is rotatably connected to the intermediate connecting plate 1133. The top end of the elastic member 1132 is connected to the intermediate connecting plate 1133. The movable pipeline obstacle-clearing mechanism 110 further includes a lifting driving member 1134 for driving the intermediate connecting plate 1133 to lift and lower.

[0055] It can be understood that the lifting driving member 1134 can drive the entire barrier-breaking component 113 to lift and lower, so as to move the barrier-breaking component 113 to the working position or the storage position.

[0056] Among them, the lifting driving member 1134 can be an electric push rod. Of course, the lifting driving member 1134 can also be in other driving forms such as pneumatic or hydraulic.

[0057] As Figure 3 As shown, in some embodiments, blocking portions 1113 extending downward are provided on the left and right sides of the bottom of the main body 1111. The bottom of the blocking portion 1113 is higher than the bottom of the driving wheel 1112.

[0058] It can be understood that when the barrier-breaking component 113 breaks the obstacle 10, the blocking portion 1113 can play a role in blocking the broken obstacle 10, reducing the risk that the obstacle 10 splashes onto the driving wheel 1112 and hits the driving wheel 1112, causing a deviation in the moving direction of the movable pipeline obstacle-clearing mechanism 110.

[0059] As Figure 1As shown, in some embodiments, a collision prevention member 114 is connected to the front end of the main body 1111. The collision prevention member 114 has a collision prevention portion located in front of the front camera 112. The collision prevention portion is used to protect the front camera 112. Among them, the collision prevention member 114 can be a rigid collision prevention bracket, which can physically protect the front camera 112.

[0060] It should be noted that when the front camera 112 detects that the movable pipeline obstacle clearing mechanism 110 approaches an insurmountable obstacle 10, it can issue an alarm to prompt the operator to make a judgment or avoid it. If the operator does not give a timely response, automatic avoidance or shutdown operations can be performed.

[0061] Of course, to detect whether there is an insurmountable obstacle 10 in front of the movable pipeline obstacle clearing mechanism 110, it can also be known through a radar or other image sensing components.

[0062] As Figure 1 As shown, in some embodiments, a handle 118 is connected to the main body 1111. The handle 118 is rotatably connected to the main body 1111, and the handle 118 can be operably flipped upward or downward. In this way, it is convenient for the user to carry the movable pipeline obstacle clearing mechanism 110.

[0063] Specifically, when it is necessary to carry the movable pipeline obstacle clearing mechanism 110, the handle 118 can be turned up for easy carrying by the user. When it is not necessary to carry the movable pipeline obstacle clearing mechanism 110, the handle 118 can be turned down and folded to reduce the occupied space.

[0064] The present utility model also provides a pipeline maintenance device, including the above-mentioned movable pipeline obstacle clearing mechanism 110.

[0065] In the pipeline maintenance device of the present utility model, the movable pipeline obstacle clearing mechanism 110 can move inside the pipeline and clear the obstacles 10 inside the pipeline. The front camera 112 is arranged at the front end of the main body 1111 and can collect the images in front of the movable pipeline obstacle clearing mechanism 110, and the images can be displayed on the display panel communicatively connected to the front camera 112. When the movable pipeline obstacle clearing mechanism 110 moves inside the pipeline, the obstacle breaking component 113 can break the obstacles 10, and the bottom of the obstacle breaking component 113 is higher than the bottom of the driving wheel 1112, which can prevent the obstacle breaking component 113 from hindering the normal movement of the movable pipeline obstacle clearing mechanism 110. Specifically, when the movable pipeline obstacle clearing mechanism 110 moves inside the pipeline, if the obstacle breaking element 1131 encounters an obstacle 10, first, the obstacle breaking element 1131 will first abut against the obstacle 10, and then, as the movable pipeline obstacle clearing mechanism 110 continues to move forward in the pipeline, the elastic element 1132 will be slowly stretched, and the stretched elastic element 1132 will exert a greater force on the obstacle breaking element 1131, thereby increasing the force exerted by the obstacle breaking element 1131 on the obstacle 10 and improving the obstacle breaking effect. In addition, as the movable pipeline obstacle clearing mechanism 110 continues to move forward in the pipeline, relative to the main body 1111, the front end of the obstacle breaking element 1131 will slowly tilt downward, so that the direction of the force exerted by the obstacle breaking element 1131 on the obstacle 10 will slowly tilt downward. When the obstacle breaking element 1131 breaks the obstacle 10 subsequently, the front end of the obstacle breaking element 1131 will gradually shovel downward, so that more of the obstacle 10 can be broken.

[0066] In the description of this specification, the descriptions referring to terms such as "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples", etc. mean that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present utility model. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0067] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model, and the scope of the present utility model is defined by the claims and their equivalents.
