Description

Technical Field

[0001] The invention belongs to the field of drainage pipes, and in particular relates to an inspection robot with a dredging function for drainage pipes. Background Art

[0002] Drainage pipes refer to the system composed of pipes and their ancillary facilities that collect and discharge sewage, wastewater and rainwater. They include trunk pipes, branch pipes and pipes leading to treatment plants. No matter whether they are built on the streets or anywhere else, as long as they are used for drainage, they should be counted as drainage pipes.

[0003] For the unblocking of industrial drainage pipes, in order to clearly understand the blockage situation inside the pipes, a patrol robot will be used first to enter the drainage pipes for inspection, which can help the staff to clearly understand the blockage situation inside the pipes. Then, according to the blockage situation, unblocking tools will be used to perform unblocking operations.

[0004] In the related art, the inspection robot is generally composed of an integrated shell, on which a driving mechanism, a camera mechanism, a control mechanism, etc. are arranged. When in use, the staff uses an external controller to control the inspection robot to move inside the pipeline, and obtains the image of the inside of the pipeline through the camera mechanism. Therefore, most of them only have a single inspection function. When there are some small blockages inside the pipeline, they cannot handle the blockages because they do not have the unblocking function. At the same time, the blockages will also affect the movement of the inspection robot inside the pipeline, preventing it from continuing to move forward to complete the inspection task.

[0005] Therefore, it is necessary to provide a patrol robot with a dredging function for drainage pipes to solve the above technical problems. Summary of the invention

[0006] In view of this, the present invention aims to provide a patrol robot with a dredging function for drainage pipes, so as to solve the problem that the patrol robot does not have the dredging function.

[0007] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0008] A patrol robot with a dredging function for a drainage pipe comprises a shell and a dredging and cleaning structure and a moving structure arranged thereon. The dredging and cleaning structure comprises a rotating shaft, a driving motor, a first bevel gear and a cleaning piece. One end of the rotating shaft is located inside the shell, and the other end extends to the outside of the shell, and both ends of the rotating shaft are horizontally rotatably connected to the shell. A first bevel gear is arranged on the periphery of the rotating shaft. The driving motor is fixed on the shell and is located below the rotating shaft. A first bevel gear is arranged on the output end of the driving motor. The two first bevel gears are meshed on the periphery. The cleaning piece is vertically arranged on the free end of the rotating shaft. The moving structure comprises two driving pulleys and a floating fixed pulley, which are used to drive the shell to move in the pipe.

[0009] Furthermore, the cleaning piece includes a fixing frame and a scraper. The fixing frame is vertically arranged at the front end of the rotating shaft. A long hole is arranged at the upper end of the fixing frame. A positioning rotating piece is arranged on one side of the scraper. The positioning rotating piece is slidably connected to the long hole on the fixing frame.

[0010] Furthermore, the cleaning piece also includes a tension spring, which is located in the long hole on the fixing frame, one end of which is connected to the positioning rotating piece, and the other end of which is connected to the inner wall of the top end of the long hole.

[0011] Furthermore, the floating fixed pulley is arranged on the top of the shell, and an elastic sliding rod is arranged at the bottom of the floating fixed pulley. The elastic sliding rod includes a telescopic spring and a movable sliding rod. One end of the telescopic spring is fixedly connected to the bottom of the floating fixed pulley, and the other end is fixedly connected to the top of the movable sliding rod. The movable sliding rod is horizontally arranged inside the shell, and both ends are slidably connected to the inner walls on both sides of the shell.

[0012] Furthermore, the moving structure also includes a second bevel gear, a rotating member, and a third bevel gear. The second bevel gear is arranged on the periphery of the output end of the driving motor. The two rotating members are arranged inside the shell and symmetrically on both sides of the first rotating shaft. The rotating member is rotatably connected to the shell. A third bevel gear is arranged on the periphery of each rotating member, and the two third bevel gears are respectively meshed with the second bevel gear.

[0013] Furthermore, the driving pulleys are arranged on both sides of the bottom of the shell, a groove is arranged in the middle of each driving pulley, and a transmission belt is arranged on the groove for transmission connection between the driving pulley and the rotating member.

[0014] Furthermore, the shell is in the shape of a triangular prism, the two driving pulleys are respectively arranged at the side ridges of the bottom of the shell, and the floating fixed pulley is located at the side ridges of the top.

[0015] Furthermore, a detachable inspection panel is provided at the front end of the shell, a lighting lamp is provided outside the inspection panel, and a camera is also provided outside the shell for monitoring the internal environment of the pipeline.

[0016] Furthermore, the inspection robot also includes a collection structure, which includes a suction pump, a collection bucket, an absorption head and an output pipe. The collection bucket is movably arranged inside the shell, the absorption head opening is downwardly arranged at the bottom of the shell, the suction pump is arranged on one side of the inner wall of the shell, the suction pump input end is connected to one side of the absorption head, the suction pump output end is connected to the output pipe, and the free end of the output pipe is located at the top of the collection bucket.

[0017] Furthermore, the top of the collecting bucket is in an open state, and a lock buckle is fixedly provided on the outside of the collecting bucket for fixing the rope.

[0018] Compared with the prior art, the inspection robot with dredging function for drainage pipes described in the present invention has the following beneficial effects:

[0019] (1) The present invention discloses a patrol robot with a dredging function for drainage pipes. The dredging and cleaning structure is provided, and is mainly used to effectively clean the debris inside the pipes. The patrol robot has the function of automatically dredging the pipes. When patrolling the inside of the pipes, the cleaning element is driven to rotate by the motor, and finally rotates, and contacts with the inner wall of the pipes to effectively clean the inner wall of the pipes. The dredging operation of the pipes is completed while patrolling the inside of the pipes. There is no need to perform a separate dredging operation on the pipes. The patrol robot not only has the basic patrol function, but also changes the traditional design form, making it more worry-free when used.

[0020] (2) The present invention provides a patrol robot with a dredging function for drainage pipes. The mobile structure is arranged to cooperate with the dredging and cleaning structure. When the dredging and cleaning structure is in operation, the mobile structure is started synchronously, so that the patrol robot can move inside the pipe. On the one hand, the inner wall of the pipe is cleaned by the dredging and cleaning structure, so that the patrol robot can move smoothly in the pipe, thereby improving the patrol efficiency of the patrol robot and avoiding obstacles that affect the movement of the patrol robot. On the other hand, the use cost of the power structure is reduced. The two share a power structure, which reduces the internal mass of the patrol robot and reduces the pressure on the pipe during inspection, while greatly reducing the manufacturing cost.

[0021] (3) The inspection robot with dredging function for drainage pipes described in the present invention has two driving pulleys arranged at two side edges of the bottom of the shell so that when the inspection robot moves, its exterior will not contact the bottom of the inner wall of the pipe, and a certain gap will be formed between the two, so that the cleaned debris will not contact the outside of the shell, which can effectively prevent the debris from accumulating on the front side or bottom of the shell and affecting the movement of the inspection robot, making the inspection robot move more smoothly and safely.

[0033] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0034] First embodiment

[0035] like Figure 1-Figure 4 As shown, a patrol robot with a dredging function for a drainage pipe comprises: a shell 1; a dredging and cleaning structure 2, wherein the dredging and cleaning structure 2 is arranged in the shell 1, and the dredging and cleaning structure 2 is used to dredge and clean the inside of the pipe, the dredging and cleaning structure 2 comprises a rotating shaft 21 and a driving motor 22 for driving the rotating shaft 21 to rotate, one end of the rotating shaft 21 is rotatably connected to one side of the inner wall of the shell 1, and the other end of the rotating shaft 21 extends from the inside of the shell 1 to the outside thereof, the cleaning member 24 and the rotating shaft 21 are arranged in a vertical state, the driving motor 22 is arranged at the bottom of the shell 1, the outside of the rotating shaft 21 and the output end of the driving motor 22 are both installed with a first bevel gear 23, and the outsides of the two first bevel gears 23 are meshed, and one end of the rotating shaft 21 and located outside the shell 1 is installed with a cleaning member 24 for cleaning the blockage on the inner wall of the pipe; a moving structure 3, wherein the moving structure 3 is arranged on the shell 1, and the moving structure 3 is used to drive the shell 1 to move horizontally inside the pipe.

[0036] The dredging and cleaning structure 2 is mainly used for cleaning the internal blockages of the pipeline, wherein the rotating shaft 21 is horizontally arranged on the shell 1, and its left end is rotatably connected to one side of the inner wall of the shell 1, and can rotate on the shell 1. The driving motor 22 is externally connected to a power source, and its operation is controlled by an external controller. The driving motor 22 is located directly below the rotating shaft 21, and its output end is meshed with a first bevel gear 23 fixedly installed on the outside of the rotating shaft 21. When the driving motor 22 rotates, the rotating shaft 21 can be rotated synchronously; the cleaning member 24 is located at the front side of the shell 1, and maintains a vertical state with the rotating shaft 21. When the rotating shaft 21 rotates, the cleaning member 24 rotates on the inner wall of the pipeline at the same time, and the cleaning member 24 includes a fixed frame and a scraper, and the fixed frame is fixedly installed with the front end of the rotating shaft 21, and a long hole is provided on the upper end of the fixed frame, and a scraper is provided on one side. The positioning rotating member is slidably connected to the long hole on the fixed frame. Through the cooperation and sliding of the two, the scraper can slide in the vertical direction on the fixed frame. One end of the positioning rotating member is tightly fitted with one side of the fixed frame. The friction force generated when the positioning rotating member is tightly fitted with the outside of the fixed frame can effectively fix the position of the scraper, so that the scraper can maintain a stable state. The scraper is slidably connected to the outside of the fixed frame. A tension spring is arranged on the scraper. The tension spring is located in the long hole on the fixed frame, one end of which is connected to the positioning rotating member, and the other end is connected to the inner wall of the top of the long hole, so that the scraper has an outward thrust and has a position adjustment function. The length of the scraper can be adjusted according to the specific size of the pipeline, so that the outer side of the scraper can effectively contact the inner wall of the pipeline, and the impurities and blockages adsorbed on the inner wall of the pipeline can be effectively cleaned through the rotation of the scraper.

[0037] The movable structure 3 includes two driving pulleys 31, a floating fixed pulley 32, a second bevel gear 33 and a rotating member 34. The two driving pulleys are respectively mounted on both sides of the outside of the shell 1, the floating fixed pulley 32 is mounted on the top of the shell 1, and an elastic slide bar is provided at the bottom of the floating fixed pulley 32 to ensure the thrust of the floating fixed pulley 32 outward; the second bevel gear 33 is mounted on the outside of the output end of the driving motor 22; the rotating member 34 is rotatably mounted on the inside of the shell 1, and the two rotating members 34 are respectively located on the left and right sides of the outside of the rotating shaft 21, the outside of the rotating member 34 is connected to the outside of the driving wheel 31 through a transmission belt, and a third bevel gear 35 is installed on the outside of the rotating member 34, and the outsides of the two third bevel gears 35 are respectively meshed with the two sides of the outside of the second bevel gear 33; the movable structure 3 can be used in conjunction with the dredging and cleaning structure 2. When the driving motor 22 rotates, the two driving pulleys 31 can rotate, thereby allowing the inspection robot to move horizontally inside the pipeline. The driving pulley 31 is installed at the side edges on both sides of the bottom of the shell 1. When the inspection robot enters the pipeline, the two driving pulleys 31 can maintain a stable state inside the pipeline by contacting both sides of the inner wall of the pipeline. A groove is provided in the middle of the driving pulley 31, which is connected to the transmission wheel on the rotating member 34 through a transmission belt transmission, so that the rotating member 34 can drive the driving pulley 31 to rotate at the same time. The rotating member 34 is rotatably installed inside the shell 1, and the third bevel gear 35 outside it is adapted to the second bevel gear 33. Through the meshing of the two, when the second bevel gear 33 rotates, the two third bevel gears 35 can be driven to rotate at the same time, and finally the two driving pulleys 31 can rotate, realizing the simultaneous linkage effect of the dredging and cleaning structure 2 and the moving structure 3.

[0038] When the inspection robot moves, the dredging and cleaning structure 2 rotates synchronously. On the one hand, the inner wall of the pipeline is cleaned by the dredging and cleaning structure 2, so that the inspection robot can move smoothly in the pipeline, thereby improving the inspection efficiency of the inspection robot and avoiding obstacles that affect the movement of the inspection robot. On the other hand, the use cost of the power structure is reduced. The two share a power structure, which reduces the internal mass of the inspection robot and reduces the pressure on the pipeline during inspection, while greatly reducing the production cost. In addition, in order to allow the debris cleaned from the inner wall of the pipeline to fall to the bottom of the inner wall of the pipeline and avoid always following the rotation of the cleaning part 24, the inspection robot will stop moving after moving a certain distance, so that the cleaning part 24 is in a horizontal state. The specific movement cycle is adjusted by an external controller, and after the debris falls to the bottom of the inner wall of the pipeline, it can be washed away by the water inside the pipeline.

[0039] like Figure 1As shown, the overall shape of the shell 1 is set to a triangular prism, and the two driving pulleys 31 are respectively located at the side edges on both sides of the bottom of the shell 1, and the floating fixed pulley 32 is located at the side edge position of the top of the shell 1, and the two driving pulleys 31 and the floating fixed pulley 32 are in contact with the inner wall of the pipeline through the thrust of the spring, so that the shell 1 can stably move inside the pipeline; the shell 1 is set to a triangular prism shape, which can well adapt to the internal structure of the pipeline and can move at any angle. The two driving pulleys 31 and the floating fixed pulley 32 outside can provide effective support for the outside of the shell 1, so that it can stably move inside the pipeline; the front side of the shell 1 is installed with an inspection plate 4 for sealing the front side of the shell 1, and the outside of the inspection plate 4 is installed with a lighting lamp 5 for illuminating the inside of the pipeline, and the outside of the shell 1 is installed with a camera 6 for real-time monitoring of the internal environment of the pipeline; the lighting lamp 5 and the camera 6 are both connected to the power supply inside the shell 1, and are used for illuminating the inside of the pipeline and graphic monitoring, respectively, so that the staff can clearly see the internal situation of the pipeline from the outside.

[0040] The working principle of the inspection robot with dredging function for drainage pipes provided by the present invention is as follows: when in use, the inspection robot is placed inside the pipe so that the lighted driving pulley 31 and the floating fixed pulley 32 on its outside can contact the inner wall of the pipe respectively, and then the dredging cleaning structure 2 is started to make the driving motor 22 start to rotate, thereby making the two first bevel gears 23 start to rotate, and at the same time drive the rotating shaft 21 to rotate, and the rotating shaft 21 rotates so that the cleaning piece 24 can rotate, and the outside of the cleaning piece 24 contacts the inner wall of the pipe, which can clean up the debris on the inner wall of the pipe and finally fall into the pipe. The bottom position of the inner wall of the pipeline; while the driving motor 22 rotates, the second bevel gear 33 rotates at the same time, thereby driving the two third bevel gears 35 outside it to rotate, so that the two rotating members 34 can rotate, and the two driving pulleys 31 rotate through the rotation of the rotating member 34, so that the entire inspection robot can move inside the pipeline, and at the same time, the interior of the pipeline is illuminated by the lighting lamp 5, and the camera 6 monitors the internal situation of the pipeline and uploads it to the external controller in real time, thereby completing the inspection of the interior of the pipeline, and then controlling the driving motor 22 to rotate in the opposite direction, so that the inspection robot can move out of the pipeline.

[0041] Second embodiment

[0042] Based on the first embodiment of the present invention, a patrol robot with a dredging function for drainage pipes, the second embodiment of the present invention provides another patrol robot with a dredging function for drainage pipes, wherein the second embodiment does not hinder the independent implementation of the technical solution of the first embodiment.

[0043] Specifically, another inspection robot with a dredging function for drainage pipes provided by the present invention is different in that: a collecting structure 7 for collecting blockages in the pipe is arranged inside the shell 1, and the collecting structure 7 includes a suction pump 71, a collecting bucket 72 and an absorption head 73, the suction pump 71 is installed on one side of the inner wall of the shell 1, the collecting bucket 72 is movably installed inside the shell 1, and the absorption head 73 is installed at the bottom of the shell 1; the input end of the suction pump 71 is connected to one side of the absorption head 73 through a pipe, and the output end of the suction pump 71 is connected to an output pipe 74, and the other end of the output pipe 74 is located at the top of the collecting bucket 72; the top of the collecting bucket 72 is in an open state, and the outer side of the collecting bucket 72 is maintained on the same plane as the side outside the shell 1, and a lock buckle 8 for fixing a rope is fixedly installed on one side of the outside of the shell 1.

[0044] The collecting structure 7 is mainly used for collecting some of the cleaned debris that is difficult to be washed away by water. The suction pump 71 is connected to the power supply unit inside the shell 1, and its input end is connected to the absorption head 73 through a pipeline, so that the absorption head 73 has suction, and the absorption head 73 opens downward, and can suck the cleaned debris at the bottom of the pipeline, and the collecting bucket 72 is used to collect the sucked debris, and its top is open, and the output end of the suction pump 71 is located at the top of the collecting bucket 72 through the output pipeline 74, so that the absorbed garbage can directly fall into the collecting bucket 72, and the collecting bucket 72 extends from the inside of the shell 1 to the outside of the shell 1, and the collecting bucket 72 can be pulled from the outside to separate it from the inside of the shell 1, so as to clean the debris inside it. The collecting structure 7 is mainly used to collect the debris that has been cleaned up. For some debris that is difficult to be washed away by water, the suction pump 71 can be started to make it sucked by the absorption head 73 and then transported to the collecting bucket 72. When used in conjunction with the unblocking and cleaning structure 2, the unblocking ability of the inspection robot can be further increased, avoiding the use of other unblocking means to deal with the debris later, and the cleaning can be completed in one step, which is more worry-free when used; the lock buckle 8 is mainly used to install ropes. Before the inspection robot enters the pipeline, the rope is used to connect to the outside of the lock buckle 8. The rope is used to increase the safety protection of the inspection robot. When it fails and cannot move, the rope can be pulled to pull the inspection robot out.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
