Description

Pipe cleaning detection method TECHNICAL FIELD

[0001] A pipe cleaning detection method, in particular, a simple pipe cleaning detection method using a pressurizing device to push a high-pressure water or air to push a cleaning head to the inside of the cleaned pipe. BACKGROUND

[0002] Referring to FIG. 1A, a pipe 2, such as a pipe for various transportation or various production, is provided. After the pipe 2 is set up and used for a long time, the inner wall 20 of the pipe 2 is scaled 23 and blocked, which causes the liquid flowing in the pipe 2 to reduce the transportation and production efficiency.

[0003] The existing device for cleaning the inner wall 20 of the pipe 2 is disclosed in the inventor's previous research and development of Taiwan TW I599739 patent. Referring to FIG. 1A, the surface of the pipe cleaning head 1 has a plurality of scrapers 11. The pipe cleaning head 1 is pushed into the pipe 2 from the inlet end 21 of the pipe 2 by the pushing pressure 13 generated by the pressurizing device 12, and the pipe cleaning head 1 is pushed into the outlet end 22 of the pipe 2 from the inlet end 21 of the pipe 2 to clean the inner wall 20 of the pipe 2. When the condition of the inner wall 20 of the pipe 2 after cleaning is detected, referring to FIG. 1B, the same pressurizing device 12 is used to generate the pushing pressure 13 to push the viewing device 14 into the outlet end 22 of the pipe 2 from the inlet end 21 of the pipe 2. The viewing device 14 is provided with a camera 141 inside the memory to access the photographic image stored in the memory, and the inner wall 20 of the pipe 2 is observed to see if it is clean. The position of the inner wall 20 of the pipe 2 that is not clean is calculated to provide for further cleaning or replacement and repair. Since the camera 141 is used to take pictures at high speed, a high-quality camera 141 is required, which is relatively expensive. Moreover, when the viewing device 14 moves at high speed in the pipe 2, it may collide with the remaining dirt removed by the pipe cleaning head 1, causing the camera 141 to be obscured during the pushing process and unable to be viewed. Even if it is damaged, it needs to be replaced, which increases the trouble and cost. Therefore, a faster, simpler and less expensive detection method is developed.

[0028] The structure of the present application is combined and used as follows in conjunction with the accompanying drawings, and the purpose, technical content, characteristics and effects achieved by the present application should be easier to understand.

[0029] Please refer to Figure 2 and combine Figures 3 to 8, a pipeline cleaning detection method 3 is disclosed by the present application, which includes the following steps:

[0030] Step A: using a pressurizing device 7 to push a cleaning head into a pipeline 6 for cleaning, and then a first soft circular column 4 is inserted into the inlet end 61 of the pipeline 6;

[0031] Step B: the first soft circular column 4 is pushed from the inlet end 61 of the pipeline 6 to the outlet end 62 of the pipeline 6 by the propulsion pressure 71 generated by the pressurizing device 7 connected outside the inlet end 61 of the pipeline 6, and the first soft circular column 4 will scrape and remove the remaining dirt 8 left by the previous cleaning head and clean it out again;

[0032] Step C: a second soft circular column 5 is inserted into the inlet end 61 of the pipeline 6; and

[0033] Step D: the second soft circular column 5 is pushed from the inlet end 61 of the pipeline 6 to the outlet end 62 of the pipeline 6 by the propulsion pressure 71 generated by the pressurizing device 7 connected outside the inlet end 61 of the pipeline 6, and when the second soft circular column 5 passes through the pipeline 6, the outer surface of the second soft circular column 5 is observed, and when the outer surface of the second soft circular column 5 produces many damaged scratches, especially deeper grooves 52, it indicates that the previous cleaning head of the pipeline 6 has not removed the dirt 8 fixed on the inner wall 60 of the pipeline 6, and it needs to be cleaned again, if the outer surface of the second soft circular column 5 is not damaged or has shallow damage, it indicates that the pipeline 6 has been cleaned completely.

[0034] And its execution step B in the first soft round column 4 listed three preferred implementation state, the following detailed description. As shown in Figure 3 to Figure 5, the first soft round column 4 diameter is slightly larger than the inner diameter of the pipeline 6, one end of the convex cone 41, the other end forms a flat 42, so that the first soft round column 4 plug in the pipeline 6 inner wall 60 and with the pipeline 6 inner diameter form a tight state.

[0035] And its execution step C in the second soft round column 5 preferred implementation state, the following detailed description. As shown in Figure 6 and Figure 7, the second soft round column 5 diameter is slightly larger than the inner diameter of the pipeline 6, two ends respectively form a vertical plane 51, so that the second soft round column 5 plug in the pipeline 6 inner wall 60 and with the pipeline 6 inner diameter form a tight state.

[0036] In the implementation of the matching step, as shown in Figure 3 to Figure 5, when the pipeline 6 is detected, through step A in the pipeline 6 inlet end 61 in the first soft round column 4; when the execution step B, using water pressure or air pressure method of the pressurizing device 7 generated by the propulsion pressure 71, the first soft round column 4 from the pipeline 6 inlet end 61 to the pipeline 6 outlet end 62, when the first soft round column 4 through the pipeline 6, the slope 410 of the cone 41 and the pipeline 6 inner wall 60 form a space 411 can be brought out of the falling dirt 8, at the same time, fixed in the pipeline 6 inner wall 60 of the dirt 8 first impact extrusion of the slope 410 of the cone 41 and force is small than not easy to be damaged, so the first soft round column 4 is suitable for the selection of not easy to be damaged foaming material and its elasticity, strength and toughness is good, and can be used for a period of time; when the execution step C, as shown in Figure 6 and Figure 7, in the pipeline 6 inlet end 61 in the second soft round column 5; again through step D, as shown in Figure 6 to Figure 8, using water pressure or air pressure method of the pressurizing device 7 generated by the propulsion pressure 71, the second soft round column 5 from the pipeline 6 inlet end 61 to the pipeline 6 outlet end 62, when the second soft round column 5 through the pipeline 6, using the vertical plane 51, so that the dirt 8 fixed in the pipeline 6 inner wall 60 directly impact force is large, easy to let the second soft round column 5 outer surface produce many damaged scratch groove 52, especially have the deeper groove 52, indicating that the pipeline 6 previous cleaning head is not clean dirt 8 fixed in the pipeline 6 inner wall 60, need to be cleaned again, if the second soft round column 5 outer surface is not damaged or shallow injury, indicating that the pipeline 6 has been cleaned, benefit to the operator in the pipeline 6 after cleaning detection. Therefore, the second soft round column 5 is selected to be damaged easily foaming material and the strength is worse than the first soft round column 4.

[0037] Referring to FIG. 3 to FIG. 8, when the advancing pressure 71 of the pressurizing device 7 in the pipeline 6 encounters a large bend in the pipeline 6 during the advancement of the first soft circular cylinder 4, if the pressurizing device 7 is a water pressurizing device, the water pressure of the pressurizing device 7 can push the first soft circular cylinder 4 that is stopped in the pipeline 6 with a large bend forward. If the pressurizing device 7 is an air pressurizing device, when the first soft circular cylinder 4 encounters a large bend in the pipeline 6 and cannot advance, the pressurizing device 7 senses the stoppage and continues to pressurize. The pressurizing device 7 continues to pressurize until the first soft circular cylinder 4 is pushed through the large bend in the pipeline 6 and advances further. The space 411 of the first soft circular cylinder 4 can conveniently carry out the fallen dirt 8. At the same time, the dirt 8 fixed to the inner wall 60 of the pipeline 6 first impacts and presses the inclined surface 410 of the cone 41 and is less likely to be damaged under less force. Therefore, the first soft circular cylinder 4 is suitable to use foamed material that is not easily damaged and can be repeatedly used for a period of time. Then, the advancing pressure 71 of the pressurizing device 7 pushes the second soft circular cylinder 5 into the pipeline 6 from the inlet end 61 to the outlet end 62 of the pipeline 6, as shown in FIG. 8. When the second soft circular cylinder 5 passes through the pipeline 6, the vertical plane 51 is used to make the dirt 8 fixed to the inner wall 60 of the pipeline 6 directly impact under a large force, which easily causes many damaged scratches and grooves 52, especially deep grooves 52, on the outer surface of the second soft circular cylinder 5, indicating that the previous cleaning head of the pipeline 6 has not completely removed the dirt 8 fixed to the inner wall 60 of the pipeline 6 and needs to be cleaned again. If the outer surface of the second soft circular cylinder 5 is not damaged or has shallow damage, it indicates that the pipeline 6 has been completely cleaned. Therefore, the second soft circular cylinder 5 is selected to use foamed material that is easily damaged and has a lower strength than the first soft circular cylinder 4.

[0038] Referring to FIG. 9, which is an embodiment two of the first soft circular cylinder 4a of the present application. The first soft circular cylinder 4a of the present application is also used to detect the pipeline 6 to conveniently carry out the fallen dirt 8 that is scraped and discharged by the previous cleaning head. The structure and function of the first soft circular cylinder 4a are substantially the same as the first soft circular cylinder 4 disclosed in FIG. 4 and FIG. 5. The only difference is that the first soft circular cylinder 4a has a convex cone 41a at both ends. Both ends of the first soft circular cylinder 4a can be used. The diameter of the first soft circular cylinder 4a is slightly larger than the inner diameter of the pipeline 6. The first soft circular cylinder 4a fills the inner wall 60 of the pipeline 6 and forms a close fit with the inner diameter of the pipeline 6. The space 411 formed by the inclined surface 410a of the cone 41a and the inner wall 60 of the pipeline 6 can conveniently carry out the fallen dirt 8. At the same time, the dirt 8 fixed to the inner wall 60 of the pipeline 6 first impacts and presses the inclined surface 410a of the cone 41a and is less likely to be damaged under less force.

[0039] Referring to FIG. 10, it is an embodiment three of the first soft circular cylinder 4b of the present application. The first soft circular cylinder 4b is also used to detect the pipeline 6 to scrape the remaining dirt 8 discharged from the previous cleaning head and clean it out again. Its structure and function are substantially the same as the first soft circular cylinder 4 disclosed in FIG. 4 and FIG. 5, but the difference is that the two ends of the first soft circular cylinder 4b are respectively provided with a convex portion 41b in the shape of a circular arc. The two ends of the first soft circular cylinder 4b can be used, and its arrangement and function for detecting the pipeline 6 are the same as the first soft circular cylinder 4 disclosed in FIG. 3. Therefore, no further description is given here.

[0040] However, the above-mentioned preferred embodiments are intended to enable those skilled in the art to understand the content of the present application and to implement it, and are not intended to limit the scope of the present application. Therefore, any equivalent changes or modifications made in shape, structure and features according to the scope of the present application should be included in the scope of the patent application of the present application.
