Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline cleaning, and in particular relates to a high-pressure water cleaning device for a petroleum pipeline. Background Art

[0002] Cleaning of oil pipelines is an important maintenance task, which is crucial to ensure the smooth, safe and efficient operation of pipelines. Sediments on the inner wall of the pipeline will increase flow resistance and reduce transportation efficiency. Reduced transportation efficiency will lead to increased energy consumption and higher operating costs.

[0003] At present, there is a pipe inner wall jet cleaning device on the market with announcement number CN207507927U, which includes a fixed base and a rotating base connected to the fixed base. The fixed base is arranged on a supporting component, and the rear end of the fixed base is connected to a high-pressure hose. Nozzles are evenly arranged on the outer circumference of the rotating base, and the nozzles face the side and rear of the rotating base. The supporting component includes a bracket body and supporting legs evenly distributed around the bracket body in a circumference. One end of the supporting leg is hinged to the bracket body and the other end is provided with a walking wheel. A left-right rotation adjustment component is hinged between the front supporting leg and the rear supporting leg arranged on the same plane, which is used to adjust the state of the front and rear wheel legs to adapt to different pipe inner diameters. This new device can adapt to changes in the inner diameter of the pipe by adjusting the state of the supporting legs and replacing the connecting pipe where the nozzle is installed. It is convenient and fast, and is suitable for cleaning operations of pipes with various inner diameters.

[0004] But there is also a problem: when there are impurities in the pipe that have not been cleaned out, the rollers can easily get stuck. Utility Model Content

[0005] The utility model provides a high-pressure water cleaning device for a petroleum pipeline, which is used to solve the problem that a roller is easily stuck when traveling in a pipeline.

[0006] The present invention provides a high-pressure water cleaning device for oil pipelines, including a main body: the main body is used to be placed in the pipeline; a connecting rod: the connecting rod is matched with the main body; a thrust nozzle: the thrust nozzle is connected to the main body through the connecting rod, and the thrust nozzle is matched with the pipeline; a roller: a plurality of rollers are provided, and the plurality of rollers are distributed in a circle with the main body; a water pump; a water inlet pipe: one end of the water inlet pipe is connected to the water pump, and the other end is connected to the thrust nozzle. Adjustment mechanism: the adjustment mechanism includes: a vertical rod: the vertical rod is rotatably connected to the roller; a telescopic rod: one end of the telescopic rod is fixedly connected to the main body, and the other end is slidably connected to the inside of the vertical rod; an adjustment spring: one end of the adjustment spring is fixedly connected to the main body, and the other end is fixedly connected to the vertical rod, and the adjustment spring is coaxially arranged with the telescopic rod.

[0007] The principle of this solution is that when the pipeline needs to be cleaned, the device is placed inside the pipeline so that the roller contacts the inner wall of the pipeline, the roller support body is located in the center of the pipeline, the operator starts the water pump, the thrust nozzle is aimed at the pipeline obliquely, and the body moves forward due to the reaction force of the water flow while cleaning the inner wall of the pipeline. When the roller encounters impurities that have not been cleaned, the roller will expand and contract due to the adjustment of the spring, and the roller will roll over the impurities without getting stuck.

[0008] The beneficial effect of this solution is that: this solution enables the roller to adjust its length autonomously through the adjustment mechanism, thereby preventing the roller from being stuck due to impurities.

[0009] Furthermore, it also includes a rotating joint, the connecting rod and the main body are rotatably connected through the rotating joint, and the thrust nozzle is fixedly connected to the connecting rod at an angle of 30°-60°. The thrust nozzle is arranged at a position close to the tangential direction of the connecting rod. When the thrust nozzle sprays water, the recoil force can not only provide forward power, but also make the connecting rod rotate, so that the thrust nozzle can clean all directions of the inner wall of the pipeline.

[0010] Furthermore, it also includes a scraping mechanism, which includes a cleaning rod and a cleaning ball, wherein the cleaning rod is fixedly connected to the main body, and the cleaning rod is located between the connecting rod and the roller, and the cleaning ball is fixedly connected to the cleaning rod, and the cleaning ball cooperates with the pipeline. Oil stains often adhere to the inner wall of the oil pipeline, and it is not easy to remove them by water flushing. In this solution, when the thrust nozzle sprays water, the connecting rod will rotate, causing the cleaning rod to rotate, and the cleaning rod will drive the cleaning ball to rotate, and the cleaning ball will rotate and scrape the inner wall of the pipeline, and at the same time, the water flow sprayed by the thrust nozzle will flush the cleaning ball, thereby ensuring the service life of the cleaning ball.

[0011] Furthermore, it also includes a drill bit, which cooperates with the connecting rod. When the oil pipeline is blocked, if there is no device to break it in front, it is easy for the whole device to be unable to move forward. However, the drill bit of this solution is set on the connecting rod and is located at the front. When the thrust nozzle sprays water, the connecting rod rotates, and the rotation of the connecting rod drives the drill bit to rotate. When the pipeline is blocked, the drill bit can break up the blocking block in front, so that the whole device can pass.

[0012] Furthermore, it also includes a breaking nozzle, the drill bit is provided with an inner groove, the breaking nozzle is fixedly connected to the inner groove, and the breaking nozzle is connected to the water inlet pipe, and a solenoid valve is provided at the connection point between the breaking nozzle and the water inlet pipe, the head of the breaking nozzle is located outside the drill bit, and the breaking nozzle is aligned with the center of the pipe. If a more stubborn blockage is encountered, the operator can open the solenoid valve at this time so that the water pressure of the water pump is simultaneously provided to the breaking nozzle, so that the breaking nozzle sprays a high-pressure water line to break the blockage in front. After the breaking is completed, the solenoid valve is closed and the forward cleaning continues. This mechanism improves the cleaning ability of the blockage.

[0013] Furthermore, it also includes a control mechanism, which includes a contact block, a return spring, a controller and a push switch, the push switch is fixed on the inner groove, the push switch is electrically connected to the controller, the controller is electrically connected to the solenoid valve, one end of the return spring is fixedly connected to the breaking nozzle, and the other end is fixedly connected to the contact block, and the contact block cooperates with the push switch.

[0014] When the drill bit does not encounter a hard blockage, the drill bit will keep rotating. The rotation of the drill bit will cause the contact block to be affected by centrifugal force, so that the contact block contacts and presses on the push switch. The push switch sends an electrical signal, and the controller controls the solenoid valve to close.

[0015] When the drill bit encounters a hard blockage, the drill bit will be stuck in the blockage under the thrust of the thrust nozzle and then stop rotating. At this time, the contact block will return to its original position under the action of the reset spring. At this time, the push switch is not triggered, and the controller controls the solenoid valve to open, so that the water flow of the water pump is diverted to the breaking nozzle, and the breaking nozzle sprays a high-pressure water line to break the front.

[0016] This mechanism will automatically start the breaking nozzle only when encountering a hard blockage. Compared with the existing solution of constantly starting the breaking nozzle, this solution will not cause damage to the pipeline.

[0017] Furthermore, the drill bit is a plastic drill bit, which has lower strength than an alloy drill bit, thus preventing the drill bit from damaging the pipeline. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] Basically as attached Figure 1 As shown:

[0022] This solution provides a high-pressure water cleaning device for oil pipelines, including a main body 1, which is a cylindrical shell with a hollow interior to reduce the weight of the main body 1 and facilitate forward movement. The right end of the main body 1 is rotatably connected to a rotating joint 8, and 4x2 rollers 2 and an adjustment mechanism are arranged around the main body 1 at equal intervals. The main body 1 is smaller than the diameter of the pipeline 3 as a whole, and the rollers 2 contact the inner wall of the pipeline 3 under the action of the adjustment mechanism.

[0023] The vertical rod is connected to the roller in a rolling manner, and the adjustment mechanism includes an adjustment spring 5 and a telescopic rod 6. One end of the adjustment spring 5 is fixedly connected to the main body 1, and the other end is fixedly connected to the vertical rod. One end of the telescopic rod 6 is fixedly connected to the main body 1, and the other end is slidably connected to the vertical rod. The water pump is located outside the pipeline 3, one end of the water inlet pipe 4 is connected to the water pump, and the other end is connected to the rotating joint 8.

[0024] The connecting rod 11 is a hollow connecting rod, one end of which is connected to the rotating joint 8, and the other end is connected to the thrust nozzle 10. A cleaning rod 9 is also fixed between the thrust nozzle 10 and the main body 1. The cleaning rod 9 is parallel to the connecting rod 11, and a cleaning ball 7 is provided at the end of the cleaning rod 9. The cleaning ball 7 just contacts the inner wall of the pipe 3, and the thrust nozzle 10 can also spray the cleaning ball 7. The thrust nozzle 10 and the connecting rod 11 are 45 degrees, so that when the thrust nozzle 10 sprays water, it can drive the connecting rod 11 to rotate and provide a forward reverse thrust.

[0025] As attached Figure 2 As shown:

[0026] A drill bit 12 is fixedly connected to the top of the connecting rod 11. The drill bit 12 is a plastic drill bit 12 to prevent the drill bit 12 from damaging the pipeline 3. The drill bit 12 is provided with an inner groove, and a breaking nozzle 15 is fixed in the inner groove. The breaking nozzle 15 is connected to the thrust nozzle 10. The breaking nozzle 15 is provided with an electromagnetic valve 16. The water outlet of the breaking nozzle 15 is located outside the drill bit 12 and in front of the drill bit 12.

[0027] It also includes a control mechanism, which includes a contact block 13, a return spring 17, a controller and a push switch 14. The push switch 14 is fixed on the inner groove, the push switch 14 is electrically connected to the controller, the controller is electrically connected to the solenoid valve 16, one end of the return spring 17 is fixedly connected to the breaking nozzle 15, and the other end is fixedly connected to the contact block 13, and the contact block 13 and the push switch 14 are on the same horizontal line.

[0028] As attached Figure 1 , Figure 2 As shown:

[0029] The principle of this solution is that when the pipe 3 needs to be cleaned, the device is placed inside the pipe 3 so that the roller 2 contacts the inner wall of the pipe 3, the roller 2 supports the main body 1 in the center of the pipe 3, the operator starts the water pump, the thrust nozzle 10 is obliquely aimed at the pipe 3, and while cleaning the inner wall of the pipe 3, the main body 1 moves forward due to the reaction force of the water flow. At the same time, the thrust nozzle 10 also generates a rotational force, causing the connecting rod 11 to rotate, so that the thrust nozzle 10 can clean all directions of the inner wall of the pipe 3.

[0030] When the connecting rod 11 rotates, the cleaning rod 9 rotates, and the cleaning rod 9 drives the cleaning ball 7 to rotate. The cleaning ball 7 rotates and scrapes the inner wall of the pipe 3. At the same time, the water flow sprayed by the thrust nozzle 10 will flush the cleaning ball 7 to ensure the service life of the cleaning ball 7. At the same time, the rotation of the connecting rod 11 drives the drill bit 12 to rotate. When the pipe 3 is blocked, the drill bit 12 can break up the blockage in front so that the entire device can pass. When the drill bit 12 does not encounter a hard blockage, the drill bit 12 will keep rotating. The rotation of the drill bit 12 will cause the contact block 13 to be affected by centrifugal force, so that the contact block 13 contacts and presses on the push switch 14. The push switch 14 sends an electrical signal, and the controller controls the solenoid valve 16 to close.

[0031] When the drill bit 12 encounters a hard blockage, the drill bit 12 will be stuck in the blockage under the thrust of the thrust nozzle 10, and then stop rotating. At this time, the contact block 13 will return to its original position under the action of the reset spring 17. At this time, the push switch 14 is not triggered, and the controller controls the solenoid valve 16 to open, so that the water flow of the water pump is diverted to the breaking nozzle 15, and the breaking nozzle 15 sprays a high-pressure water line to break the front. When the roller 2 encounters impurities that have not been cleaned, the roller 2 will expand and contract due to the adjustment spring 5, and the roller 2 will roll over the impurities and will not get stuck.

[0032] The beneficial effects of this solution are as follows: 1. This solution enables the roller 2 to adjust its length autonomously through the adjustment mechanism, thereby preventing the roller 2 from getting stuck due to impurities. 2. The breaking nozzle 15 can help break up the blockage, thereby improving the cleaning ability of the blockage. 3. This mechanism will automatically start the breaking nozzle 15 only when encountering a hard blockage. Compared with the existing method of always starting the breaking nozzle 15, this solution will not cause damage to the pipeline 3.
