Description

Technical Field

[0001] The invention relates to the technical field of pipeline cleaning, and in particular to a device for cleaning and descaling the inner wall of a petroleum pipeline. Background Art

[0002] Grease scale in oilfield pipelines is generally composed of various impurities and sediments in the oil, such as minerals, wax, sand, salts, etc. These grease scales are gradually deposited on the inner wall of the pipeline as the oil flows. The current descaling methods are commonly mechanical cleaning and chemical cleaning. The mechanical cleaning method is generally to flush with a high-pressure water gun, and then use mechanical equipment such as scrapers or brushes to scrape the grease scale from the inner wall of the pipeline after flushing. Chemical cleaning is to use chemical solvents or cleaning agents to stay in the pipeline for a period of time to dissolve the grease scale, and then use clean water or other solvents to flush and remove the pipeline;

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Example 1: Please refer to Figures 1 to 8 As shown, the present invention is a device for cleaning and descaling the inner wall of a petroleum pipeline, comprising a support base 1, a processing frame 2 is fixedly connected to the upper surface of the support base 1, a partition plate 3 is fixedly connected inside the processing frame 2, a cleaning pipe 4 is movably sleeved inside the partition plate 3, and a control panel 5 is fixedly connected to the upper end of one side of the processing frame 2;

[0036] A servo motor 6 is fixedly connected to the upper surface of the processing frame 2, an adjusting shaft 7 is internally connected to the lower surface of the servo motor 6, and the lower end of the adjusting shaft 7 is rotatably connected to the partition plate 3, a guide slide 8 is sleeved on the outer portion of the adjusting shaft 7, and the guide slide 8 is slidably connected to the processing frame 2, the upper end of the cleaning pipe 4 is located below the guide slide 8 and is fixedly connected to a driven wheel 9, a cleaning scraper 10 is provided at the lower end of the cleaning pipe 4, a driving motor 11 is fixedly connected to the upper surface of the guide slide 8, and a driving wheel 12 is internally connected to the lower surface of the driving motor 11;

[0037] That is, when cleaning the oil pipe, first install the oil in the oil pipe, control the rotating motor 17 to drive the positioning seat 18 to work, and then drive the oil pipe to rotate, and at the same time, the servo motor 6 and the driving motor 11 run synchronously, and the servo motor 6 drives the adjusting shaft 7 to rotate, so that the adjusting shaft 7 drives the external guide slide 8 to move downward inside the processing frame 2, and at the same time, the guide slide 8 drives the cleaning pipe 4 to move downward inside the partition plate 3, and at the same time, the driving motor 11 drives the transmission wheel 12 to rotate, and through the transmission between the gears, the transmission wheel 12 drives the driven wheel 9 to rotate, and then the driven wheel 9 drives the cleaning pipe 4 to rotate, so as to achieve the effect of rotating and moving the cleaning pipe 4 downward, and the rotation direction of the cleaning pipe 4 is opposite to the rotation direction of the oil pipe;

[0038] In the embodiment of the present invention, the cleaning scraper 10 is connected to the cleaning pipe 4 via a hollow spring, and the cleaning scraper 10 is used to clean and descale the inner wall of the oil pipe;

[0039] A positioning sleeve 13 is movably sleeved on the outside of the cleaning pipe 4 and below the driven wheel 9. A moving slide 14 is fixedly connected to the end of the positioning sleeve 13 away from the cleaning pipe 4. A telescopic rod 15 is fixedly connected to the lower end of the moving slide 14. A cleaning plate 16 is fixedly connected to the end of the telescopic rod 15 away from the moving slide 14. That is, as the cleaning pipe 4 moves downward, the cleaning pipe 4 drives the moving slide 14 to move vertically downward inside the partition plate 3 through the positioning sleeve 13. The lower end of the cleaning plate 16 enters the inner wall of the oil pipe and squeezes the telescopic rod 15 at the same time, so that the cleaning plate 16 and the inner wall of the oil pipe are closely fitted, and the inside of the oil pipe is cleaned and descaled. At the same time, due to the self-rotation of the oil pipe, the cleaning effect of the cleaning plate 16 is improved.

[0040] In the embodiment of the present invention, a positioning spring is set inside the telescopic rod 15, that is, when the cleaning plate 16 is squeezed, the cleaning plate 16 drives the telescopic rod 15 to work, so that the spring inside the telescopic rod 15 is elastically deformed, and then the cleaning plate 16 can achieve the telescopic function, so as to clean the inside of the oil pipe;

[0041] A rotating motor 17 is fixedly connected to the upper surface of the support seat 1, and a positioning seat 18 is internally connected to the upper surface of the rotating motor 17 in a transmission manner. The outer portion of the positioning seat 18 is located above the processing frame 2 and is fixedly sleeved with a limiting gear 19. A support plate 20 is fixedly connected to the upper end of the positioning seat 18. A guide cylinder 21 is inserted into the inner portion of the support plate 20. An end of the guide cylinder 21 close to the guide slide 8 is fixedly connected to a limiting clamp 22. An end of the guide cylinder 21 away from the guide slide 8 is fixedly connected to a self-locking plate 23, and an end of the self-locking plate 23 away from the guide cylinder 21 cooperates with the limiting gear 19. A limiting spring is arranged between the support plate 20 and the limiting clamp 22 and on the outer portion of the guide cylinder 21. A through hole matching the moving slide 14 is provided inside the partition plate 3, and a water outlet is provided at the lower end of the cleaning pipe 4.

[0042] That is, when installing the oil pipe, the lower end of the oil pipe is placed on the support plate 20, and the limit clamp 22 drives the guide cylinder 21 to move inside the support plate 20, causing the limit spring to undergo elastic deformation, thereby causing the limit clamp 22 to clamp and position the middle oil pipe. At the same time, during the movement of the guide cylinder 21, the guide cylinder 21 drives the self-locking plate 23 to move, thereby separating the self-locking plate 23 from the limit gear 19 so that the positioning seat 18 can rotate. When the oil pipe is removed, the self-locking plate 23 self-locks the limit gear 19, which facilitates the stability of the subsequent oil pipe installation, and can not only achieve the clamping and positioning of the oil pipe, but also achieve the effect of stable installation, while providing auxiliary effect for the subsequent cleaning of the cleaning plate 16.

[0043] Embodiment 2: A supervision platform, a data collection unit, a control and supervision unit, a feedback self-checking unit and a management response unit are arranged inside the control panel 5;

[0044] When the supervision platform detects that the equipment starts to run, it generates a supervision instruction and sends the supervision instruction to the data acquisition unit. When the data acquisition unit receives the supervision instruction, it immediately collects the cleaning data of the equipment and sends the cleaning data to the control and supervision unit. After receiving the cleaning data, the control and supervision unit immediately performs a cleaning safety supervision evaluation and analysis on the cleaning data to determine whether the cleaning effect of the oil pipe meets the standard, so as to adjust the equipment in time to improve the cleaning effect of the equipment. The specific cleaning safety supervision evaluation and analysis process is as follows:

[0045] The time period when the equipment starts running is collected and set as the time threshold. The time threshold is divided into i sub-time periods, where i is a natural number greater than zero. The cleaning data of the equipment in each sub-time period is obtained. The cleaning data includes flushing water pressure, cleaning speed and downward movement speed. A rectangular coordinate system is established with the number of sub-time periods as the X-axis and the cleaning data as the Y-axis. The cleaning data curve is drawn by plotting points to obtain the maximum peak value and minimum trough value of the flushing water pressure, cleaning speed and downward movement speed. The difference between the maximum peak value and the minimum trough value of the flushing water pressure, cleaning speed and downward movement speed is analyzed and set as the water pressure interference value, the speed interference value and the movement speed interference value. The water pressure interference value, the speed interference value and the movement speed interference value are labeled SG, ZG and YG respectively. The cleaning effect risk coefficient is obtained according to the formula Q=SG×ZG×YG×f1, where f1 is the preset correction factor coefficient, f1 is greater than zero, and Q is the cleaning effect risk coefficient. The cleaning effect risk coefficient Q is compared and analyzed with the preset cleaning effect risk coefficient threshold value entered and stored internally:

[0046] If the ratio between the cleaning effect risk factor Q and the preset cleaning effect risk factor threshold is greater than 1, a risk signal is generated;

[0047] If the ratio between the cleaning effect risk coefficient Q and the preset cleaning effect risk coefficient threshold is less than or equal to 1, a stability signal is generated, and the risk signal and the stability signal are sent to the management response unit. After receiving the risk signal and the stability signal, the management response unit immediately performs the preset early warning operation corresponding to the risk signal and the stability signal, so as to clean and adjust the equipment in time to ensure the cleaning effect and cleaning stability of the equipment;

[0048] When a stable signal is generated, the feedback self-checking unit responds to the stable signal and collects the inner wall characteristic image of the oil pipe, and performs cleaning verification feedback analysis on the inner wall characteristic image to determine whether the inner wall of the oil pipe is cleaned, so as to reasonably perform secondary cleaning. The specific cleaning verification feedback analysis process is as follows:

[0049] The inner wall feature image of the oil pipe within the time threshold is obtained, and the inner wall feature image of the oil pipe is compared and analyzed with the qualified inner wall feature image after the oil pipe is cleaned, so as to obtain the difference value between the inner wall feature image of the oil pipe and the qualified inner wall feature image after the oil pipe is cleaned, and the difference value is discriminated:

[0050] If the difference value is less than the preset difference value threshold, a qualified signal is generated;

[0051] If the difference value is greater than or equal to the preset difference value threshold, a secondary cleaning signal is generated, and the qualified signal and the secondary cleaning signal are sent to the management response unit. After receiving the qualified signal and the secondary cleaning signal, the management response unit immediately performs the preset warning operation corresponding to the qualified signal and the secondary cleaning signal, so as to timely perform secondary cleaning on the inner wall of the oil pipe to ensure qualified cleaning of the inner wall of the oil pipe, thereby helping to improve the cleaning effect of the inner wall of the oil pipe;

[0052] In summary, when the oil pipe is installed, the lower end of the oil pipe is placed on the support plate 20, so that the limit clamp 22 drives the guide cylinder 21 to move inside the support plate 20, and at the same time, the limit spring is elastically deformed, so that the limit clamp 22 clamps and positions the middle oil pipe. At the same time, during the movement of the guide cylinder 21, the guide cylinder 21 drives the self-locking plate 23 to move, so that the self-locking plate 23 is separated from the limit gear 19, so that the positioning seat 18 can rotate. When the oil pipe is removed, the self-locking plate 23 self-locks the limit gear 19, which is convenient for the stability of the subsequent oil pipe installation, and can not only achieve the clamping and positioning of the oil pipe, but also achieve the effect of stable installation, and at the same time provide auxiliary effect for the subsequent cleaning of the cleaning plate 16;

[0053] After the oil pipe is installed, the rotating motor 17 is controlled to drive the positioning seat 18 to work, drive the oil pipe to rotate, the servo motor 6 and the driving motor 11 run synchronously, and the servo motor 6 drives the adjusting shaft 7 to rotate, so that the adjusting shaft 7 drives the external guide slide 8 to move downward inside the processing frame 2, and at the same time, the guide slide 8 drives the cleaning pipe 4 to move downward inside the partition plate 3. At the same time, the driving motor 11 drives the transmission wheel 12 to rotate, and through the transmission between the gears, the transmission wheel 12 drives the driven wheel 9 to rotate, and then the driven wheel 9 drives the cleaning pipe 4 to rotate, so as to achieve the effect of rotating and moving the cleaning pipe 4 downward, and the rotation direction of the cleaning pipe 4 is opposite to the rotation direction of the oil pipe;

[0054] As the cleaning pipe 4 moves downward, the cleaning pipe 4 drives the cleaning scraper 10 to clean and descale the inner wall of the oil pipe. At the same time, the cleaning pipe 4 drives the moving slide plate 14 to move vertically downward inside the partition plate 3 through the positioning sleeve 13, so that the lower end of the cleaning plate 16 enters the inner wall of the oil pipe, and at the same time, the telescopic rod 15 is squeezed to make the cleaning plate 16 fit closely with the inner wall of the oil pipe, and the inside of the oil pipe is cleaned and descaled. At the same time, due to the self-rotation of the oil pipe, the cleaning effect of the cleaning plate 16 is improved;

[0055] After cleaning, upon receiving the supervision instruction, the data acquisition unit immediately collects the cleaning data of the equipment and sends the cleaning data to the control and supervision unit. After receiving the cleaning data, the control and supervision unit immediately performs a cleaning safety supervision assessment and analysis on the cleaning data to determine whether the cleaning effect of the oil pipe meets the standard, so as to adjust the equipment in time to ensure the cleaning effect and cleaning stability of the equipment. Through information feedback, the feedback self-inspection unit responds to the stable signal and collects the characteristic image of the inner wall of the oil pipe, and performs a cleaning verification feedback analysis on the characteristic image of the inner wall to determine whether the inner wall of the oil pipe is clean, so as to perform secondary cleaning reasonably to ensure the qualified cleaning of the inner wall of the oil pipe, which in turn helps to improve the cleaning effect of the inner wall of the oil pipe.

[0056] The threshold is set to facilitate comparison. The threshold depends on the amount of sample data and the number of bases set by technicians in this field for each group of sample data; as long as it does not affect the proportional relationship between the parameter and the quantified value. The above formulas are obtained by collecting a large amount of data and performing software simulation, and a formula close to the true value is selected. The coefficients in the formula are set by technicians in this field according to the actual situation;

[0057] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.

7. The device for cleaning and descaling the inner wall of a petroleum pipeline according to claim 6, characterized in that: The cleaning safety supervision assessment and analysis process of the control and supervision unit is as follows: The time period when the equipment starts to run is collected and set as the time threshold. The time threshold is divided into i sub-time periods, where i is a natural number greater than zero. The cleaning data of the equipment in each sub-time period is obtained, and the cleaning data includes flushing water pressure, cleaning speed and downward movement speed. A rectangular coordinate system is established with the number of sub-time periods as the X-axis and the cleaning data as the Y-axis. The cleaning data curve is drawn by plotting points to obtain the maximum peak value and minimum trough value of the flushing water pressure, cleaning speed and downward movement speed. The difference between the maximum peak value and the minimum trough value of the flushing water pressure, cleaning speed and downward movement speed is analyzed and set as the water pressure interference value, the speed interference value and the movement speed interference value. The water pressure interference value, the speed interference value and the movement speed interference value are labeled SG, ZG and YG respectively. The cleaning effect risk coefficient is obtained according to the formula Q=SG×ZG×YG×f1, where f1 is the preset correction factor coefficient, f1 is greater than zero, and Q is the cleaning effect risk coefficient.
