Description

Technical Field

[0001] This invention relates to the field of pipeline cleaning technology, and more particularly to a pipeline robot. Background Technology

[0002] Pipelines serve as fundamental infrastructure in industries such as water, natural gas, and oil. As pipelines age, they inevitably experience problems such as internal siltation and pipe damage, leading to various safety hazards. Therefore, regular pipeline safety inspections are essential.

[0003] Wheeled pipeline robots offer advantages such as high stability, flexible operation, high speed, and the ability to carry large loads. Multiple drive wheel sets are evenly distributed across the robot's body, each driven by a motor and equipped with a retractable mechanism. When performing inspection tasks, the pipeline robot can move forward through the pipeline by driving each drive wheel set. Furthermore, when encountering changes in pipeline diameter or bends, the extension or retraction of support components in the support mechanism can be adjusted to meet the needs of different working environments.

[0004] However, if some drive wheels malfunction while the pipeline robot is working inside the pipeline, it can easily prevent the robot from exiting the pipeline on its own, requiring human intervention to pull it out using traction ropes or other means. When a malfunction occurs, the support components may extend and press against the pipe wall, or the robot may encounter obstacles it had previously avoided during the extraction process, making extraction difficult or even permanently leaving it inside the pipeline. Power outages or other factors can also cause the drive wheels to stop operating. Summary of the Invention

[0034] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0035] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of the invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0036] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms do not 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 on the scope of protection of this invention.

Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0038] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0040] like Figure 1-9 As shown, the present invention provides a pipeline robot, comprising: a drive mechanism 1, a detection mechanism 2, a functional mechanism 3, an auxiliary wheel mechanism 4, and a universal joint mechanism 5.

[0042] The detection mechanism 2 and the functional mechanism 3 are evenly distributed in two rows of auxiliary wheel mechanisms 4 along the circumference; the functional mechanism rear connecting plate 303 on the functional mechanism 3 can still be connected to other functional mechanisms 3 through the universal joint mechanism 5, and the number of functional mechanisms 3 is gradually increased.

[0043] Example 2

[0044] like Figure 2-5As shown, the drive mechanism 1 of the present invention includes: an energy storage mechanism 11, a support mechanism 13 and a drive wheel mechanism 14.

[0046] The support mechanism 13 includes a central shaft 1308 and a central support 1301; the central shaft 1308 has a front end plate 1307 and a rear end plate 1302 at its two ends respectively; one end of the front end plate 1307 is connected to the energy storage mechanism 11; the central support 1301 is connected to the front end plate 1307 and the rear end plate 1302 by an inner sleeve 1303 and an outer sleeve 1304; the inner sleeve 1303 is located inside the outer sleeve 1304 and the two slide relative to each other; both ends of the inner sleeve 1303 are connected to the front end plate 1307 and the rear end plate 1302 by flanges 1309; the outer sleeve 1304... Both ends are connected to the central support 1301 via flanges 1309; several circular holes for connecting springs 1306 are evenly distributed on the outer periphery of the central support 1301; a support frame 1305 is provided at the top of the spring 1306; eight long connecting rods 1311 are connected to the two side walls of the support frame 1305 via pins 1310; four long connecting rods 1311 are distributed between the support frame 1305 and the front end plate 1307 and the rear end plate 1302; one side of the support frame 1305 is connected to a short connecting rod 1312 located on the protruding shaft of the outer sleeve 1304 via two long connecting rods 1311 to form a parallelogram structure.

[0048] The energy storage mechanism 11 is implemented as follows: During the movement of the pipeline robot, the impeller 1101 is rotated by the pressure difference on both sides. The impeller shaft has a thread and meshes with the threaded hole in the middle of the slide rail 1109. When the impeller 1103 rotates, the slide rail 1109 is constrained by the track 1102 and can only move back and forth on the track 1102. Thus, the rotational motion of the impeller 1101 is converted into the translational motion of the slide rail 1109. When the slide rail 1109 moves, the connecting plate 1103 mounted on it and the magnet 1104 fixed on the connecting plate 1103 also move. The magnet 1104 moves continuously in the coil 1105, cutting the magnetic field lines and generating a certain current according to Faraday's law of electromagnetic induction. The coil 1105 and the energy storage battery 1106 can be connected by a wire to store the generated electrical energy and connect to the geared motor 1401 through the wire, providing another power supply method when connected to an external power source.

[0049] The drive support mechanism 13 is implemented as follows: a spring 1306 in the circular hole on the central support 1301 presses against the support frame 1305 and the drive wheel mechanism 14. At the same time, the spring is telescopic to ensure that the drive mechanism can be applied to pipes of different diameters. The support frame 1305, the long connecting rod 1311, and the short connecting rod 1312 set on the outer sleeve 1304 form a parallelogram mechanism. Two sets of the parallelogram mechanism are respectively set between the front end plate 1307 and the support frame 1305 and between the rear end plate 1302 and the support frame 1305, and displacement compensation is performed during the extension and contraction of the spring. Optionally, a small spring is added between the inner sleeve 1303 and the outer sleeve 1304 to ensure the tension of the parallelogram mechanism formed by the connecting rod.

[0050] The drive wheel mechanism 14 is implemented as follows: the geared motor 1401 is determined by the clutch 1402 to connect to the bevel gear set 1407. When the clutch 1402 is connected, the geared motor 1401 drives the bevel gear set 1407, thereby driving the wheel axle 1406 and the drive wheel 1403 on the wheel axle 1406 to rotate, thereby driving the entire drive mechanism to move.

[0051] Example 3

[0052] like Figure 6-9 As shown, the detection mechanism 2 of the present invention includes: a first connecting plate 201, a second connecting plate 205, and a housing 206; the first connecting plate 201 and the second connecting plate 205 are respectively connected to the two ends of the housing 206; the housing 206 is divided into upper and lower parts; the upper and lower parts of the housing 206 are connected by a rotatable gear ring 203; a camera 207 is provided on the outside of the gear ring 203; a support rod 208 is provided at the center of the inside of the housing 206; the support rod 208 is internally connected to the first connecting plate 201 and the second connecting plate 205; a motor 204 is provided on the second connecting plate 205; the motor 204 is connected to a cylindrical gear 202 through a motor shaft; the cylindrical gear 202 meshes with the inside of the gear ring 203; the detection mechanism 2 drives the cylindrical gear 202 to rotate through the motor 204, thereby driving the cylindrical gear 202 to mesh with the gear ring 203 to rotate, so that the camera 207 on the gear ring 203 can perform 360° pipeline detection.

[0053] The functional mechanism 3 includes a third connecting plate 301, a body 302, and a fourth connecting plate 303; the two ends of the body 302 are respectively connected to the third connecting plate 301 and the fourth connecting plate 303; a number of auxiliary wheel mechanisms 4 are provided on the outside of the body 302; and sensors are provided inside the functional mechanism 3.

In each auxiliary wheel mechanism 4, the passive device outer sleeve 403 is electrically driven. The passive device outer sleeve 403 drives the passive device inner sleeve 402, and the moving fixed link 406, the moving link 405, and the passive wheel axle 404 form a parallelogram mechanism. When the passive device outer sleeve 403 is pulled up, the passive device inner sleeve 402 moves and extends at the same time to compensate for displacement, and at the same time drives the parallelogram mechanism on the other side. When the passive device outer sleeve 403 is lowered, the passive device inner sleeve 402 moves and retracts at the same time to compensate for displacement, and at the same time drives the parallelogram mechanism on the other side. The movement of the electrically driven passive device outer sleeve 403 ensures that the non-driven mechanism can adapt to different pipe diameters.
