Description

Technical Field

[0001] This invention belongs to the field of spiral propeller technology, and in particular relates to an anti-entanglement spiral propeller structure for pipeline robots. Background Technology

[0002] With the development of industrial automation and intelligence, pipeline robots have been widely used in fields such as petroleum, natural gas, chemical industry, and municipal engineering. Pipeline robots are mainly used for the inspection, maintenance, and repair of pipeline interiors. Their main functions include cleaning the pipeline inner wall, corrosion detection, crack detection, and weld inspection. Due to the complex internal environment of pipelines, with various obstacles, bends, and pipe walls of different materials, pipeline robots often encounter various challenges during their movement. One major problem is the entanglement of the pipeline robot's propellers.

[0003] Currently, most common pipeline robot propellers employ traditional propeller-type structures, which present numerous problems in practical applications. For instance, in pipeline environments transporting entangled debris such as fibers, cables, and plastic bags, the propeller blades are easily entangled. Entanglement not only increases the propeller's operating resistance and reduces propulsion efficiency, but in severe cases, it can even cause the propeller to jam, rendering the pipeline robot unable to function properly, thus affecting the entire operation and causing significant economic losses. Furthermore, existing propeller structures lack flexibility in the distribution and control of propulsion force, making it difficult to adapt to complex working conditions with different pipe diameters, varying pipe wall conditions, and diverse operational requirements. Summary of the Invention

[0004] The purpose of this invention is to provide an anti-entanglement spiral propeller structure for pipeline robots. Through the action of a crushing blade, when there are entangled debris such as fibers, cables, or plastic bags inside the pipeline, the crushing blade rotates at high speed with a transmission rod driven by a second motor, shredding the debris and preventing it from entangled on the spiral shaft or propeller blades. This reduces propulsion resistance, prevents the propeller from jamming, and reduces the risk of propeller failure due to entanglement by crushing debris. This ensures the normal operation of the pipeline robot under complex working conditions, improves work efficiency and equipment reliability, and solves the problem that existing spiral propeller structures are not flexible enough in the distribution and control of propulsion force, making it difficult to adapt to complex working conditions with different pipe diameters, different pipe wall conditions, and different operational requirements.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A pipe robot anti-entanglement spiral propeller structure includes a push shell, a first motor is fixed inside the push shell, and a spiral shaft is fixed to the output shaft of the first motor.

[0007] A connecting rod is fixed to the inner ring of the spiral shaft, and an adjuster is fixed to both ends of the connecting rod;

[0015] Several tension springs are fixed to the bottom of the movable hole.

[0016] The present invention is further configured such that: one end of the tension spring is fixed with an adjusting plate, and one side of the adjusting plate is fixed with a cleaning rod;

[0017] A cleaning brush is fixed to one end of the cleaning rod, and a first handle is fixed to the side of the adjustment plate away from the cleaning rod.

[0018] The first handle passes through the movable hole.

[0019] The present invention is further configured such that: a positioning plate is fixed inside the adjusting shell, and limit plates are fixed on both sides of the positioning plate;

[0020] A support plate is fixed to one side of the positioning plate, and a threaded tube is fixed to the surface of the support plate.

[0021] The present invention is further configured such that: a threaded rod is threadedly connected inside the threaded tube, and a bearing is fixed at one end of the threaded rod;

[0022] An adjusting block is fixed to the outer ring of the bearing, and an inclined surface is opened on one side of the adjusting block;

[0046] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0047] In this invention, unless otherwise stated, the directional terms such as "up" and "down" generally refer to the directions shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" generally refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not intended to limit this invention.

[0048] For a specific implementation example, please refer to Implementation Example 1. Figure 1-8 This invention relates to an anti-entanglement spiral propeller structure for a pipeline robot, comprising a push shell 1, inside which a first motor 2 is fixed, and the output shaft of the first motor 2 is fixed to a spiral shaft 3; a connecting rod 4 is fixed to the inner ring of the spiral shaft 3, and adjusters 5 are fixed to both ends of the connecting rod 4; the adjuster 5 includes an adjusting shell 6, which is fixedly connected to the connecting rod 4; a mounting plate 7 is fixed to one side of the adjusting shell 6, and a second motor 8 is fixed to one end of the connecting rod 4; a through hole 9 is opened on the surface of the mounting plate 7, and the output shaft of the second motor 8 passes through the through hole 9; a connecting shell 10 is fixed to the output shaft of the second motor 8, and a connecting block 11 is movably connected inside the connecting shell 10; a first threaded hole 12 is opened on both sides of the connecting shell 10, and a second threaded hole 13 is opened on both sides of the connecting block 11, and bolts 14 are threadedly connected to the first threaded hole 12 and the second threaded hole 13; a transmission rod 15 is fixed to one side of the connecting block 11, and several breaking blades 16 are fixed to the outside of the transmission rod 15.

[0049] Specifically, a cleaning plate 17 is fixed to the top of the push shell 1, and several movable holes 18 are opened on the surface of the cleaning plate 17; several tension springs 19 are fixed to the bottom of the movable holes 18.

[0050] Furthermore, an adjusting plate 20 is fixed to one end of the tension spring 19, and a cleaning rod 21 is fixed to one side of the adjusting plate 20; a cleaning brush 22 is fixed to one end of the cleaning rod 21, and a first handle 23 is fixed to the side of the adjusting plate 20 away from the cleaning rod 21; the first handle 23 passes through the movable hole 18.

[0051] The operation process of this embodiment is as follows: The first motor 2 is turned on, and its output shaft drives the spiral shaft 3 to rotate. The rotation of the spiral blades generates forward thrust, driving the pipe robot to move inside the pipe. When the spiral shaft 3 rotates, if it encounters entangled debris such as fibers or cables inside the pipe, the adjusters 5 at both ends of the connecting rod 4 begin to function. The second motor 8 is started, and its output shaft drives the connecting shell 10 to rotate through the through hole 9. The connecting block 11 inside the connecting shell 10 is fixedly connected by bolts 14, thereby driving the transmission rod 15 and the outer crushing blade 16 to rotate at high speed. The crushing blade 16 can cut up debris entangled around the spiral shaft 3 or the pusher, preventing the blades from getting stuck and reducing the pushing resistance. The cleaning plate 17 is fixed to the top of the push shell 1, and the tension spring 19 in the movable hole 18 is in its natural state, causing the adjusting plate 20 and the cleaning rod 21 to be pulled away from the surface of the spiral shaft 3. The tension of the tension spring 19 ensures that the cleaning brush 22 does not contact the spiral shaft 3, preventing it from getting stuck. When the device finishes one operation, the spiral shaft 3 needs to be cleaned quickly. For initial cleaning of surface impurities such as dirt and debris, the first handle 23 can be manually pressed down to overcome the tension of the tension spring 19, causing the adjusting plate 20 to move the cleaning rod 21 and cleaning brush 22 towards the spiral shaft 3 until the cleaning brush 22 contacts the surface of the spiral shaft. The user should hold the first handle 23 in place. As the spiral shaft 3 rotates, the cleaning brush 22 can scrub away the surface impurities. After cleaning, release the first handle 23, the tension spring 19 will return to its original position, and the cleaning brush 22 will automatically disengage from the spiral shaft 3, avoiding affecting the normal operation of the propeller. This device uses the crushing blade 16 to cut up debris such as fibers, cables, and plastic bags when they are entangled in the pipeline. The crushing blade 16 rotates at high speed with the transmission rod 15 driven by the second motor 8, preventing the debris from entangled in the spiral shaft 3 or the propeller blades, reducing propulsion resistance, preventing the propeller from jamming, and reducing the risk of propeller failure due to entanglement by crushing debris. This ensures the normal operation of the pipeline robot under complex working conditions and improves work efficiency and equipment reliability.

[0052] For a specific embodiment two, please refer to Figure 4-6 Based on the first specific embodiment, a positioning plate 24 is fixed inside the adjusting shell 6, and limit plates 25 are fixed on both sides of the positioning plate 24; a support plate 26 is fixed on one side of the positioning plate 24, and a threaded tube 27 is fixed on the surface of the support plate 26; a threaded rod 28 is threadedly connected inside the threaded tube 27, and a bearing 29 is fixed at one end of the threaded rod 28; an adjusting block 30 is fixed on the outer ring of the bearing 29, and an inclined surface 31 is opened on one side of the adjusting block 30; a second handle 32 is fixed at one end of the threaded rod 28, and the second handle 32 penetrates the adjusting shell 6; a positioning frame 33 is fixed inside the adjusting shell 6, and a moving plate 34 is rotatably connected inside the positioning frame 33; a moving block 35 is fixed at one end of the moving plate 34.

[0053] Specifically, an adjusting roller 36 is rotatably connected to the end of the movable plate 34 away from the movable block 35, and the adjusting roller 36 is rolledly connected to the inclined surface 31.

[0054] Furthermore, an adjustment hole 37 is opened on one side of the adjustment shell 6; a moving rod 38 is fixed on one side of the moving block 35, and a scraper 39 is fixed at one end of the moving rod 38; an extension plate 40 is fixed on one side of the scraper 39.

[0055] The operation process of this embodiment is as follows: Before entering the pipeline, the device rotates the second handle 32, which drives the threaded rod 28 to rotate inside the threaded tube 27. Due to the action of the bearing 29, the rotation of the threaded rod 28 is converted into the linear movement of the adjusting block 30. The adjusting roller 36 rolls in contact with the inclined surface 31. When the adjusting block 30 moves, the inclined surface 31 pushes the adjusting roller 36, causing the moving plate 34 to rotate around the positioning frame 33. This, in turn, drives the moving block 35, the moving rod 38, and the scraper 39 to extend or retract towards the inner wall of the pipeline to adapt to pipelines of different diameters. After being adjusted to the appropriate position, during the advancement of the spiral shaft 3, the scraper 39 drives the extension plate 40 to stick tightly to the inner wall of the pipeline, scraping away viscous debris or deposits on the inner wall to prevent debris from accumulating and affecting the robot's movement or entanglement of the propeller, thus ensuring smooth operation.
