Description

Technical Field

[0001] The invention relates to the technical field of pipeline cleaning equipment, and in particular to an anti-blocking pipeline cleaning device. Background Art

[0002] In the process of transporting oil and gas through pipelines, it is necessary to periodically clean the pipelines. Generally, fluid is input into the pipeline to generate thrust so that the pig can complete the cleaning and dredging of the oil and gas pipelines.

[0003] However, during the construction of oil and gas pipelines, the direction of the pipeline will change due to factors such as rivers or geological changes, resulting in large bends or diameter changes in the oil and gas pipelines. Generally, when a pig passes through a bend or diameter change, it is very easy to get stuck. When the pig is not seriously stuck, the fluid pressure in the pipeline is often increased to push the pig through the bend or diameter change smoothly. However, the pig is easily damaged due to deformation caused by excessive pressure. When the pig is seriously stuck, it is necessary to cut the oil and gas pipeline to remove the pig, which seriously increases production costs.

[0004] That is to say, the pipe cleaning device in the prior art has the problem of being difficult to deform and being easily blocked. Summary of the invention

[0028] In order to solve the problems in the prior art that pipe cleaning devices are not easily deformed and easily get stuck, the present invention provides an anti-blocking pipe cleaning device.

[0029] like Figures 1 to 3As shown, the anti-blocking pipe cleaner includes a scraper 10, at least two cleaning members 20 and a connecting hose 30. The scraper 10 is used to scrape off dirt on the inner wall of the pipe; the cleaning member 20 is used to clean dirt on the inner wall of the pipe; the two cleaning members 20 are respectively connected to the two ends of the connecting hose 30, and the scraper 10 is arranged at one end of the cleaning member 20 away from the connecting hose 30.

[0030] During the operation of the anti-blocking pipe cleaner, the scraper 10 can scrape off the dirt on the inner wall of the pipe, and then the cleaning member 20 pushes the fallen dirt forward to achieve the effect of cleaning the inner wall of the pipe. In addition, two cleaning members 20 are used in the present application, the cleaning member 20 close to the scraper 10 performs the first cleaning, and the cleaning member 20 away from the scraper 10 performs the second cleaning, thereby achieving a double cleaning effect. At the same time, a connecting hose 30 is provided in the anti-blocking pipe cleaner in the present application, and the connecting hose 30 has the advantage of good shape change, and is not easy to get stuck when encountering turns and diameter changes, thereby reducing the risk of damage to the anti-blocking pipe cleaner.

[0031] Since the connecting hose 30 is retractable, it is in a contracted state at the straight pipe section, and is in an expanded state when passing through pipe elbows and other locations, which is conducive to the movement of the anti-blocking pipe cleaner at the location of the pipe elbow and reduces the risk of blockage.

[0032] Preferably, the connecting hose 30 is a stainless steel hose.

[0033] like Figure 1 As shown, the cleaning member 20 includes a shaft body portion 21 and a cleaning portion 22, wherein the cleaning portion 22 is disposed on the shaft body portion 21, and at least a portion of the cleaning portion 22 is connected end to end along the outer peripheral side of the shaft body portion 21. The shaft body portion 21 mainly plays a supporting role to support the cleaning portion 22, and the cleaning portion 22 is used to scrape off the loose dirt of the scraping member 10, and then during the movement of the anti-blocking pig, the cleaning portion 22 pushes the dirt to move.

[0034] like Figure 1 As shown, the shaft body 21 is a conical structure, the large diameter end of the conical structure is connected to the connecting hose 30, and the scraper 10 is connected to the small diameter end of the conical structure. Setting the shaft body 21 as a conical structure is conducive to the movement of the anti-blocking pig, and the conical structure can reduce the risk of clogging the pipeline.

[0035] Preferably, the shaft body 21 is a conical structure, and the cone apex of the conical structure is 45 degrees.

[0036] like Figure 1As shown, the cleaning part 22 includes a butterfly leather cup 221 and a guide assembly 222. The butterfly leather cup 221 is connected end to end around the circumference of the shaft body 21; the guide assembly 222 is arranged on the outer periphery of the shaft body 21, and the guide assembly 222 and the butterfly leather cup 221 are arranged at intervals along the axial direction of the shaft body 21. The guide assembly 222 is used to limit and guide the anti-blocking pig, so that the anti-blocking pig moves along the inner wall of the pipeline. The butterfly leather cup 221 has a certain degree of deformability. When encountering a turn or a diameter change, the butterfly leather cup 221 will also deform, and it is not easy to get stuck.

[0037] like Figure 3 As shown, the outer circumferential surface of the shaft body 21 has a plurality of mounting holes 211, and the plurality of mounting holes 211 are arranged at intervals around the circumference of the shaft body 21. The guide assembly 222 includes a plurality of guide members 223, and the plurality of guide members 223 are arranged in a one-to-one correspondence in the plurality of mounting holes 211. The guide members 223 are movably arranged in the mounting holes 211, so that when encountering a turn or a diameter change, the guide members 223 move in the mounting holes 211, which can play a good guiding role and reduce the risk of blocking.

[0038] like Figure 1 and Figure 3 As shown, the guide member 223 includes a guide cylinder 224, a spring 225 and a guide column 226. The guide cylinder 224 penetrates the mounting hole 211; the spring 225 is arranged in the guide cylinder 224, one end of the spring 225 is connected to the shaft body 21; the guide column 226 is movably arranged in the guide cylinder 224, and the other end of the spring 225 is connected to the guide column 226. The guide cylinder 224 provides an installation space for the spring 225 and the guide column 226, and at the same time provides protection and guidance for the movement of the guide column 226 and the spring 225, so as to avoid the situation that the guide column 226 and the spring 225 are stuck, and ensure the stability of the movement of the guide column 226.

[0039] exist Figure 1 and Figure 3 In the specific embodiment shown, the end of the guide post 226 away from the spring 225 is an arc surface. This arrangement is conducive to the movement of the guide post 226 along the inner wall of the pipeline. When the inner wall of the pipeline turns, the guide post 226 can also pass smoothly to reduce the risk of blocking.

[0040] The guide cylinder 224 can not only ensure that the anti-blocking pig does not tilt, but also the spring 225 connection increases the passability of the anti-blocking pig. The guide column 226 adopts an arc surface to reduce damage to the inner wall of the pipeline.

[0041] like Figure 1As shown, the first cleaning member of the two cleaning members 20 is connected to the scraping member 10, and the other of the two cleaning members 20 is the second cleaning member. The butterfly leather cup 221 of the first cleaning member is located between the guide assembly 222 of the first cleaning member and the scraping member 10, and the butterfly leather cup 221 of the second cleaning member is close to the connecting hose 30 relative to the guide assembly 222 of the second cleaning member. In other words, the butterfly leather cup 221 is always located in the forward direction relative to the guide assembly 222, or located on the side close to the scraping member 10, so that the butterfly leather cup 221 scrapes off the dirt on the inner wall of the pipe.

[0042] The diameter of the butterfly cup 221 of the first cleaning member is slightly smaller than the inner diameter of the pipe, and the diameter of the butterfly cup 221 of the second cleaning member is equal to the inner diameter of the pipe. A signal transmitter 212 is installed in the shaft body 21 of the second cleaning member.

[0043] like Figure 1 and Figure 2 As shown, the scraping member 10 includes a rotating portion 11 and at least one brush head 12, the rotating portion 11 is connected to the cleaning member 20; the brush head 12 is arranged on the outer peripheral surface of the rotating portion 11 to scrape off the dirt on the inner wall of the pipe. The rotating portion 11 drives the brush head 12 to rotate, and the brush head 12 cleans the inner wall of the pipe so that the dirt on the inner wall of the pipe is swept off, and then the dirt is pushed to the outside of the pipe under the action of the cleaning member 20.

[0044] like Figure 1 and Figure 2 As shown, the rotating part 11 includes a bearing 111 and a plurality of fan blade brush handles 112. The bearing 111 is arranged on the cleaning member 20; the plurality of fan blade brush handles 112 are arranged at intervals around the circumference of the bearing 111, and the plurality of brush heads 12 are arranged one by one at one end of the fan blade brush handle 112 away from the bearing 111. The bearing 111 drives the fan blade brush handle 112 to rotate, and then drives the brush head 12 to rotate to clean the inner wall of the pipeline. The brush head 12 is fixedly connected to the fan blade brush handle 112. The brush head 12 uses bristles made of polyurethane. The fan blade brush handle 112 is affected by oil flow or air flow during the forward process, which can cause the fan blade brush handle 112 to rotate. The bearing connection makes it easier for the rotation to occur. The fan blade brush handle 112 drives the brush head to rotate together. The bristles made of polyurethane can not only inhibit the corrosion of oil flow or air flow, but also reduce the damage to the inner wall of the pipeline, thereby extending the service life of the pipeline.

[0045] Among them, Figure 2 In the specific embodiment shown, there are eight fan blade brush handles 112, which effectively improves the brushing efficiency. At the same time, the fan blade brush handles 112 are reinforced by wire rings.
