Technical Field

[0001] This invention relates to the field of pipe external wall cleaning equipment technology, and in particular to a pipe external wall cleaning device. Background Technology

[0002] Pipelines are common channels for transporting gas and liquids, and are widely used in various fields. However, the outer walls of pipelines are easily contaminated with dirt and grime when exposed to the external environment for extended periods, which can affect their service life.

[0003] Currently, cleaning the outer walls of pipes mainly relies on manual labor, which is inefficient, labor-intensive, and yields unsatisfactory cleaning results. To improve efficiency, some pipes are cleaned using automated cleaning equipment; however, such equipment is often ill-suited for pipes of different sizes, thus hindering its widespread adoption.

[0004] Therefore, how to provide a cleaning device that can be adapted to various pipes is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to provide a cleaning device that can be adapted to various pipes, so as to solve the problems existing in the prior art.

[0006] To achieve the above objectives, the present invention provides a pipe outer wall cleaning device, comprising:

[0007] The chassis has front and rear openings and is hollow inside, allowing pipes to pass through it from front to back.

[0008] A traveling mechanism is disposed inside the housing and in contact with the outer wall of the pipe. The traveling mechanism is used to drive the housing to move along the length of the pipe.

[0009] A cleaning mechanism is installed inside the casing and in contact with the outer wall of the pipe. When the casing moves along the length of the pipe, the cleaning mechanism can brush the outer wall of the pipe.

[0010] An adjustment mechanism is disposed inside the housing and is connected to the traveling mechanism via a transmission connection. The adjustment mechanism is used to extend and retract the traveling mechanism radially along the pipeline.

[0011] Furthermore, the chassis includes a top plate and two side plates connected to both ends of the top plate. A tension spring is connected to one side plate, and a tension spring latch is connected to the other side plate. The tension spring and the tension spring latch are detachably connected.

[0012] Furthermore, the walking mechanism includes:

[0013] The drive wheel contacts the outer wall of the pipe. The drive wheel is connected to the output end of the first drive motor via a coupling. The first drive motor is fixedly installed inside the housing.

[0014] Driven wheel, in contact with the outer wall of the pipe, at least two driven wheels are provided and arranged along the circumference of the pipe; the adjusting mechanism is used to extend and retract the driven wheel along the radial direction of the pipe.

[0015] Furthermore, the adjustment mechanism includes:

[0016] The slide rail, wherein the driven wheel is rotatably mounted on an L-shaped fixed frame, and the L-shaped fixed frame is slidably connected to the slide rail along the radial direction of the pipe;

[0017] The spring is connected at one end to the L-shaped fixing bracket and at the other end to the chassis.

[0018] Furthermore, the cleaning mechanism includes:

[0019] A rotating brush head is rotatably mounted on a brush head support. A second drive motor is provided on the brush head support to drive the rotating brush head to rotate. There are multiple rotating brush heads distributed along the circumference of the pipe.

[0024] Furthermore, the cleaning mechanism also includes:

[0025] A sponge block is installed inside the casing, located behind the rotating brush head. The sponge block can slide and rub against the outer wall of the pipe along the length of the pipe to wipe away the cleaning water on the outer wall of the pipe.

[0026] Furthermore, the chassis includes a front chassis and a rear chassis, which are arranged sequentially along the length of the pipeline and connected by connectors and universal joints; the rotating brush head is disposed in the front chassis and the sponge block is disposed in the rear chassis.

[0042] In this embodiment, the chassis includes a top plate 4 and two side plates 5 connected to both ends of the top plate 4. The chassis as a whole and the connecting parts 6 of each structure in the equipment are all made of aluminum alloy. A tension spring 21 is connected to one side plate 5, and a tension spring latch 22 is connected to the other side plate 5. The tension spring 21 and the tension spring latch 22 are detachably connected. The tension spring 21 can pull the two side plates 5 towards the direction of the pipe, improving the equipment's enclosure of the pipe and also buffering the vibration and shaking generated during equipment operation.

[0043] In this embodiment, the traveling mechanism includes: a drive wheel 8, which contacts the outer wall of the pipe. The drive wheel 8 is connected to the output end of a first drive motor 11 via a coupling 10. The first drive motor 11 is fixedly mounted inside a housing. The first drive motor 11 is preferably a DC geared motor, which has the advantages of high efficiency, low noise, and fast response speed. A driven wheel 9 contacts the outer wall of the pipe. At least two driven wheels 9 are provided and arranged circumferentially along the pipe. An adjustment mechanism is used to extend and retract the driven wheels 9 radially along the pipe. Both the drive wheel 8 and the driven wheel 9 adopt a concave structure, which makes the drive wheel 8 and the driven wheel 9 fit more closely to the outer wall of the pipe, ensuring the stability of the equipment when moving along the length of the pipe.

[0044] In this embodiment, the adjustment mechanism includes: the slide rail 14 driven wheel 9 is rotatably mounted on the L-shaped fixed frame 12, the L-shaped fixed frame 12 is slidably connected to the slide rail 14 along the radial direction of the pipe; one end of the spring 13 is connected to the L-shaped fixed frame 12, and the other end is connected to the chassis.

[0045] In this embodiment, the cleaning mechanism includes: a rotating brush head 15, rotatably mounted on a brush head support 18, with a second drive motor mounted on the brush head support 18 to drive the rotating brush head 15 to rotate; multiple rotating brush heads 15 are distributed circumferentially along the pipe, and the specific number can be determined according to the outer diameter of the rotating brush head 15, ensuring that the coordinated action of each rotating brush head 15 can thoroughly clean the entire outer wall of the pipe; in this embodiment, six cleaning brush heads are arranged in the housing; a first telescopic mechanism 19 is arranged in the housing and connected to the brush head support 18, and is used to extend and retract the brush head support 18 radially along the pipe; a water storage bottle 16 is arranged on the housing, and the water storage bottle 16 is filled with cleaning water, which can be made by mixing cleaning agent and water; a nozzle 17 is arranged in the housing and connected to the water storage bottle 16, and a valve for opening and closing can be installed on the connected pipe; the nozzle 17 faces the pipe and is used to spray cleaning water onto the outer wall of the pipe. The sponge block 3 is installed inside the casing and is located behind the rotating brush head 15. The sponge block 3 can slide along the length of the pipe and rub against the outer wall of the pipe to wipe away the cleaning water on the outer wall of the pipe.

[0046] Example 2

[0047] The difference between this embodiment and embodiment 1 is that the chassis includes a front chassis 1 and a rear chassis 2. The structures of the front chassis 1 and the rear chassis 2 are basically the same. The front chassis 1 and the rear chassis 2 are arranged sequentially along the length of the pipeline. A connector 6 is provided on the top plate 4 of the front chassis 1 and the rear chassis 2. The two connectors 6 are connected by a universal joint 7. This design adopts a hinge connection method similar to a train carriage, so that the pipeline outer wall cleaning device can be continuous when turning, is not easy to tilt or overturn, and is easy to control climbing.

[0048] The rotating brush head 15 is located inside the front housing 1, and the sponge block 3 is located inside the rear housing 2. Correspondingly, the water storage bottle 16 is also located on the top plate 4 of the front housing 1. The second telescopic mechanism 26 is located inside the rear housing and connected to the sponge block 3. The second telescopic mechanism 26 is used to move the sponge block 3 closer to or away from the pipe.

[0049] Example 3

[0050] The difference between this embodiment and Embodiment 2 is that it also includes a drive module 23, an aviation battery 20, a preset program module 24, and a remote control module 25. The drive module 23 is mounted on the front housing 1 and the rear housing 2, while the other modules are mounted on the rear housing 2. The aviation battery 20 provides power to the drive module 23, which in turn drives all power equipment, including the first telescopic mechanism 19, the second telescopic mechanism 26, the first drive motor 11, and the second drive motor, etc. The preset program module 24 is used to set the overall running time of the equipment, the length of the pipeline to be cleaned, etc., which facilitates the automation of the cleaning work. The remote control module 25 is used to establish a communication connection between the equipment and a remote terminal device, which facilitates remote operation and monitoring of the cleaning progress by the operator.

[0051] The working process is described in detail below with reference to Example 2:

[0052] Install the front housing 1 and the rear housing 2 onto the pipe in sequence, and lock the lower tension spring 21 and tension spring buckle 22. Driven wheel 9 moves along slide rail 14 under the action of spring 13, its inner surface pressing against the outer wall of the pipe. At this time, both the driving wheel 8 and the driven wheel 9 are in close contact with the outer wall of the pipe. Both the front housing 1 and the rear housing 2 are equipped with a set of driving wheels 8 and driven wheels 9, and each driving wheel 8 and driven wheel 9 works synchronously.

[0053] Adjust the first telescopic mechanism 19 and the second telescopic mechanism 26 according to the actual outer diameter of the pipe so that the rotating brush head 15 can roll and brush the pipe, and the sponge block 3 can maintain appropriate friction with the pipe and move along the length of the pipe.

[0054] The first drive motor 11 and the second drive motor are started. Under the action of the drive wheel 8, the entire device moves along the length of the pipe. During the movement, the rotating brush head 15 performs roller cleaning on the outer wall of the pipe. While the rotating brush head 15 is cleaning, the nozzle 17 sprays cleaning water from the water storage bottle 16 onto the pipe surface, improving the cleaning effect of the rotating brush head 15. The device continues to move along the length of the pipe. When the sponge block 3 moves to the area that has been roller-brushed, it wipes away the residual cleaning water on the outer wall of the pipe, completing the cleaning work of the pipe.

[0055] In the description of this invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0056] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention.
