Description

Technical Field

[0001] The present invention relates to the technical field of oil pipeline cleaning, and particularly to an oil pipeline cleaning robot. Background Art

[0002] Sediments, corrosion products, and other dirt gradually accumulate inside the oil pipeline, which will have a negative impact on the operating efficiency of the oil transportation system and the service life of the equipment. At present, most pigging devices rely on gas drive. By injecting compressed gas behind the pigging ball, when the gas pressure at the rear end exceeds the material pressure at the front end, the resulting pressure difference becomes the driving force for the pigging ball to move inside the pipeline. In contrast, the cleaning robot relies on its own propulsion mechanism to drive. When its cleaning component moves inside the pipeline, its shape contacts the inner wall of the pipeline, thereby pushing or scraping off dirt, rust, wax, and sediment on the inner wall. The oil pipeline cleaning robot generally consists of a robot main body, sensors, and a cleaning device. The robot main body can operate autonomously inside the pipeline. The sensors are used to detect the internal condition of the pipeline, and the cleaning device is responsible for cleaning the sediment and impurities inside the pipeline. During the cleaning process, the robot can collect data through the sensors and transmit it to the control center for the staff to monitor the pipeline status in real time.

[0003] However, when using the oil pipeline cleaning robot, some deficiencies have also been found. Most of the cleaning robots in the prior art adopt a fixed structure. Problems such as pipeline deformation, residual impurities, and the reduction of the inner diameter caused by wax deposition are likely to cause the robot to get stuck inside the pipeline. Once this happens, the subsequent removal work will become extremely difficult and costly. Therefore, this application proposes a new type of oil pipeline cleaning robot to address these needs. Summary of the Invention

Once this happens, the subsequent removal work will become extremely difficult and costly.

[0005] To solve the above technical problems, the present invention provides the following technical solutions:

A first mounting seat and a second mounting seat are slidably connected together on the plurality of auxiliary rods. A first fixed tube is rotatably connected between the first mounting seat and the second mounting seat. The first fixed tube is threadedly connected with the support column. The inner end of the top head is fixedly connected with a third mounting seat. A plurality of first support arms are hinged on the third mounting seat. One end of the plurality of first support arms away from the top head is hinged with a second support arm. One end of the second support arm away from the first support arm is hinged with a third support arm. One end of the third support arm away from the second support arm is hinged with the first mounting seat. A fitting rod is fixedly connected to the plurality of first support arms. The fitting rod cooperates with the second support arm and the third support arm to form a support component.

[0008] Optionally, there are multiple groups of support components, and the multiple groups of support components are arranged in a ring centered on the support column; the second leather ring, the first bending ring, the third cortex, the second bending ring, and the first leather ring are an integral elastic sleeve structure, and a plurality of guiding creases are arranged on the outer wall of the integral elastic sleeve structure.

[0009] Optionally, a plurality of fourth support arms are hinged on the second mounting seat. One end of each of the plurality of fourth support arms away from the second mounting seat is hinged with a pressing plate. Both ends of each of the plurality of pressing plates are hinged with a support plate. The plurality of support plates cooperate with each other through the plurality of pressing plates to form an annular support portion. Brush hairs are fixedly connected to the outer walls of the plurality of support plates. The plurality of brush hairs are arranged in a staggered manner, and the plurality of brush hairs pass through the third cortex. The connection between the brush hairs and the third cortex is an integral sealing structure; one end of the third mounting seat away from the top head is fixedly connected with a second fixed tube. One end of the third mounting seat is fixedly connected with a second fixed tube having the same size as the first fixed tube, and the second fixed tube abuts against the first fixed tube.

[0010] Optionally, the second rubber ring and the first rubber ring are on the same axis, and fixed rings are fixedly connected inside both the second rubber ring and the first rubber ring.

[0011] Optionally, fitting rods are fixedly connected to one ends of multiple first support arms close to the top head. The fitting rods are fixedly connected to the first leather ring, and multiple groups of support components support the integrated elastic sleeve structure. When the fitting rods are unfolded, they are in contact with the inner end of the top head.

[0012] Optionally, the first bending ring is located in the connection area between the second support arm and the first support arm, and the second bending ring is located in the area between the second support arm and the third support arm. The first bending ring and the second bending ring have the same diameter. End plates are fixedly connected to both ends of the second support arm. The two end plates respectively abut against the first support arm and the third support arm, and the two end plates respectively limit the rotation angles of the first support arm and the third support arm. Abutting blocks are fixedly connected to one ends of the first support arm close to the top head, and the abutting blocks are in contact with the top head.

[0013] Compared with the prior art, the present invention has at least the following beneficial effects:

[0014] In the above solution, by setting the cleaning and resetting component, the inner wall of the oil pipeline can be gradually cleaned, thereby improving the cleaning effect; during the contraction process of multiple support components, the support plate will be driven to fold, thereby reducing the volume of the cleaning and resetting component and facilitating the removal of the stuck device from the pipeline, solving the problem in the prior art that the cleaning robot has a fixed structure and is difficult to remove once it gets stuck; in addition, the integrated elastic sleeve structure becomes relatively smooth after contacting the sediment, which helps to reduce the friction force when the device gets stuck in the oil pipeline and further facilitates the reset of the support components.

[0015] By setting the integrated elastic sleeve structure and multiple guiding creases on the outer wall of the elastic sleeve, when the first support arm, the second support arm and the third support arm are reset, the integrated elastic sleeve structure can be synchronously driven to contract along the guiding creases. The elastic sleeve not only helps to protect the support arms and prevent the sediment from attaching and affecting the structure transmission effect, but also facilitates the overall cleaning of the device after the cleaning operation. Different from the traditional cleaning robot, each part of the integrated elastic sleeve structure will not be exposed in the pipeline, avoiding the attachment of sediment and scale and solving the problem of difficult cleaning.

[0016] By fixing the first leather ring to the fitting rod and the second leather ring to the third support arm, when the support components contract and reset, the elastic sleeve structure will fold and compress, and when the support components need to expand, the elastic sleeve structure will also expand accordingly, enabling the first bending ring and the second bending ring to be fully unfolded. After these two bending rings are unfolded, they can replace the function of the traditional leather bowl and push out the sediment in the pipeline. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] As Figures 1 to 13 shown, an embodiment of the present invention provides an oil pipeline cleaning robot, including a propulsion mechanism 1. One end of the propulsion mechanism 1 is provided with a steering column 3 and a support column 4. The propulsion mechanism 1 and the support column 4 are movably connected through the steering column 3. A magnetic line 2 is provided on the support column 4. The propulsion mechanism 1, the steering column 3 and the magnetic line 2 are all structures in the prior art cleaning robot and will not be elaborated herein in detail; it further includes a cleaning and resetting assembly connected to the support column 4, which is used for resetting and reducing the volume when the propulsion mechanism 1 cleans in the oil pipeline. The cleaning and resetting assembly includes a second push ring 7 and a pair of first push rings 6. The second push ring 7 is located between the pair of first push rings 6. The pair of first push rings 6 are used to push out the sediment on the inner wall of the oil pipeline, and the second push ring 7 is used to clean the sediment on the inner wall of the oil pipeline.

[0040] As Figure 2 、 Figures 6 to 13As shown, the cleaning and resetting assembly includes a component housing 23 fixedly connected between the support column 4 and the magnetic line 2. A remote drive mechanism is installed inside the component housing 23. The remote drive mechanism includes structures such as a drive motor, a battery, a remote control module, and a motor driver in the prior art. The forward and reverse rotation and rotation speed of the drive motor are controlled remotely, which will not be elaborated in detail here. A pair of first push rings 6 are respectively a first bent ring 11 and a second bent ring 12. A third cortex 10 is fixedly connected between the first bent ring 11 and the second bent ring 12. One end of the first bent ring 11 away from the third cortex 10 is fixedly connected to a second leather ring 9. A first rubber ring 14 is fixedly connected to the center of the second leather ring 9. One end of the second bent ring 12 away from the third cortex 10 is fixedly connected to a first leather ring 8. A second rubber ring 15 is fixedly connected to the center of the first leather ring 8; the second leather ring 9, the first bent ring 11, the third cortex 10, the second bent ring 12, and the first leather ring 8 form an integrated elastic sleeve structure. A plurality of guiding creases 13 are provided on the outer wall of the integrated elastic sleeve structure.

[0041] By providing the integrated elastic sleeve structure composed of the second leather ring 9, the first bent ring 11, the third cortex 10, the second bent ring 12, and the first leather ring 8, and by providing a plurality of guiding creases 13 on the outer wall of the elastic sleeve, when the first support arm 24, the second support arm 26, and the third support arm 27 are reset, the integrated elastic sleeve structure can be synchronously driven to contract along the guiding creases 13. The elastic sleeve not only helps to protect the support arms and prevent sediment attachment from affecting the structural transmission effect, but also facilitates the overall cleaning of the device after the cleaning operation. Different from traditional cleaning robots, each part of the integrated elastic sleeve structure will not be exposed in the pipeline, avoiding the attachment of sediment and dirt, and solving the problem of difficult cleaning; in addition, through the fixed connection of the first leather ring 8 with the fitting rod 25 and the second leather ring 9 with the third support arm 27, when the support component contracts and resets, the elastic sleeve structure will be folded and compressed; when the support component needs to expand, the elastic sleeve structure will also expand accordingly, enabling the first bent ring 11 and the second bent ring 12 to be fully unfolded. After these two bent rings are unfolded, they can replace the function of the traditional leather bowl and push out the sediment in the pipeline.

[0042] By setting up a cleaning and resetting component, when the component is used for cleaning operations, the propulsion mechanism 1 will drive the cleaning and resetting component to move along the inside of the oil pipeline. During the movement, the first bending ring 11 in the cleaning and resetting component will first contact the inner wall of the oil pipeline, thereby pushing out the sediment attached to the pipe wall; then, the bristles 32 at the rear end of the first bending ring 11 are in friction contact with the pipe wall, and this step helps to remove more stubborn and difficult-to-remove sediment; then, the second bending ring 12 connected to the rear end part of the bristles 32 continues to push out the sediment, thereby completing the entire cleaning process; in this process, since the first bending ring 11 and the second bending ring 12 are both made of elastic rubber material, they can fit the inner wall of the pipeline more flexibly, ensuring a closer contact with the pipe wall, which helps to effectively push the sediment out of the pipeline and improve the cleaning effect.

[0043] like Figures 3 to 6 As shown, the end of the support column 4 away from the component housing 23 is fixedly connected to the top head 5, and a plurality of auxiliary rods 17 are fixedly connected between the support column 4 and the top head 5. A first mounting seat 18 and a second mounting seat 19 are slidably connected to the plurality of auxiliary rods 17. A first fixed tube 20 is rotatably connected between the first mounting seat 18 and the second mounting seat 19, and the first fixed tube 20 is threadedly connected to the support column 4; a third mounting seat 22 is fixedly connected to the inner end of the top head 5, and a plurality of first support arms 24 are hinged on the third mounting seat 22, and a plurality of first support arms 24 are hinged on one end of the plurality of first support arms 24 away from the top head 5 to a second support arm 26, and a third support arm 27 is hinged on one end of the second support arm 26 away from the first support arm 24, and an end of the third support arm 27 away from the second support arm 26 is hinged to the first mounting seat 18, wherein the support The support column 4 and the auxiliary rod 17 are both fixed between the component shell 23 and the top head 5; during the cleaning process, if the robot is stuck in the pipeline, the support column 4 can be driven to rotate through the remote control structure, and the rotation of the support column 4 will drive the first mounting seat 18 and the second mounting seat 19 to move on itself. At the same time, the two mounting seats will guide the multiple support arm support components to shrink, and the support plates will be folded during the shrinkage of the multiple support components, thereby reducing the volume of the cleaning and resetting components, making it easier to remove the stuck device from the pipeline, solving the problem in the prior art that the cleaning robot is a fixed structure and is difficult to remove once it is stuck; in addition, the integrated elastic sleeve structure becomes smoother after contacting the sediment, which helps to reduce friction when the device is stuck in the oil pipeline, thereby facilitating the resetting of multiple support components.

[0044] like Figure 2 , Figure 9As shown, a plurality of fourth support arms 28 are hinged to the second mounting base 19. At one end of each of the plurality of fourth support arms 28 away from the second mounting base 19, a pressing plate 30 is hinged. At both ends of each of the plurality of pressing plates 30, a support plate 29 is hinged. Between the plurality of support plates 29, a ring-shaped support portion is formed by mutual cooperation through the plurality of pressing plates 30. A fitting rod 25 is fixedly connected to the plurality of first support arms 24. The fitting rod 25, the second support arm 26, and the third support arm 27 cooperate with each other to form a support member. There are multiple groups of support members, and the multiple groups of support members are arranged in a ring centered on the support column 4. By providing a plurality of fourth support arms 28, and the fourth support arms 28 are hinged to the plurality of support plates 29, and the plurality of support plates 29 are hinged to each other. On the outer walls of the plurality of support plates 29, a plurality of bristles 32 are fixedly connected. The bristles are of the prior art, such as steel wire bristles, etc. The plurality of bristles 32 are arranged in a staggered manner, and the plurality of bristles 32 pass through the third cortex 10. The connection between the bristles 32 and the third cortex 10 is an integrally sealed structure. By arranging the plurality of bristles in a staggered manner, the gaps between the plurality of bristles 32 are not on the same axis. Therefore, when cleaning the tube wall 32 of the bristles 32, the staggered plurality of bristles 32 can improve the cleaning effect and reduce the problem that the cleaning effect is affected by the sediment passing through the gaps between the bristles 32.

[0045] As Figure 13 shown, the second rubber ring 15 and the first rubber ring 14 are on the same axis, and a fixing ring 16 is fixedly connected inside both the second rubber ring 15 and the first rubber ring 14.

[0046] As Figure 3 、 Figure 4 shown, at one end of each of the plurality of first support arms 24 close to the top head 5, a fitting rod 25 is fixedly connected. The fitting rod 25 is fixedly connected to the first leather ring 8, and multiple groups of support members support the integrally elastic sleeve structure. When the fitting rod 25 is unfolded, it abuts against the inner end of the top head 5. By arranging the plurality of support plates 29 to be hinged to each other, and both ends of the support plate 29 are hinged to the adjacent two second support arms 26 respectively, and the inner wall of the support plate 29 is also hinged to the second mounting base 19 through the fourth support arm 28. Besides driving the support plate 29 to unfold, the second support arm 26 and the fourth support arm 28 also play a role in supporting the support plate 29, thereby improving the overall structural strength.

[0047] As Figure 5 、 Figure 7 shown, the first bending ring 11 is located in the connection area between the second support arm 26 and the first support arm 24, the second bending ring 12 is located in the area between the second support arm 26 and the third support arm 27, and the first bending ring 11 and the second bending ring 12 have the same diameter.

[0048] As Figure 8 、 Figure 10As shown, both ends of the second support arm 26 are fixedly connected with abutment plates 30, and the two abutment plates 30 abut against the first support arm 24 and the third support arm 27 respectively, and the two abutment plates 30 respectively limit the rotation angles of the first support arm 24 and the third support arm 27, and the first support arm 24 is fixedly connected with abutment block 31 at one end of the first support arm 24 close to the top head 5, and the abutment block 31 abuts against the top head 5. By setting the abutment plates 30 at both ends of the second support arm 26, since the two abutment plates 30 abut against the first support arm 24 and the third support arm 27 respectively, the first support arm 24 and the third support arm 27 are 27 will be restricted by the back plate 30 during the rotation process. To a certain extent, the back plate 30 also plays the role of supporting multiple supporting components. The end of the third mounting seat 22 away from the top head 5 is fixedly connected to the second fixed tube 21, and the one end of the third mounting seat 22 is fixedly connected to the second fixed tube 21 with the same size as the first fixed tube 20. The second fixed tube 21 and the first fixed tube 20 are in contact with each other. When the multiple supporting components are expanded and unfolded, the first fixed tube 20 will be in contact with the second fixed tube 21, thereby also playing the role of supporting the multiple supporting components.

[0049] In addition, the integrated elastic sleeve structure can be set as a double layer, and the double layer structure is fixed with buckles. The layer fixed on the support arm is the fixed layer, and the surface of the fixed layer is the replacement layer, which helps to replace the outer layer structure after it is worn.

[0050] The working principle of the technical solution provided by the present invention is as follows: when in use, the device is placed in the oil pipeline, and then the propulsion device is started. The propulsion device drives the cleaning and resetting assembly to move in the pipeline. The first curved ring 11 in the cleaning and resetting assembly will first contact the inner wall of the oil pipeline, thereby pushing out the sediment attached to the pipe wall; then, the bristles 32 at the rear end of the first curved ring 11 are in friction contact with the pipe wall. This step helps to remove more stubborn and difficult to remove sediments; then, the second curved ring 12 connected to the rear end part of the bristles 32 continues to push out the sediments, thereby completing the entire cleaning process.

[0051] During the cleaning process, if the robot is stuck in the pipe, the support column 4 is driven to rotate through the remote control structure. The rotation of the support column 4 will drive the first mounting seat 18 and the second mounting seat 19 to move on itself. At the same time, the two mounting seats will guide the multiple support arm support components to shrink. During the shrinkage of the multiple support components, the support plate will be folded, thereby reducing the volume of the cleaning and resetting assembly, making it easier to remove the stuck device from the pipe.

[0052] The present invention covers any alternatives, modifications, equivalent methods and solutions made to the essence and scope of the present invention. For the public to have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention. However, those skilled in the art can also fully understand the present invention without the description of these details. In addition, well-known methods, processes, procedures, components and circuits are not described in detail to avoid unnecessary confusion to the essence of the present invention.

[0053] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, multiple improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
