Description

Technical Field

[0001] The present application relates to the technical field of pipeline detection, and particularly relates to a pressure pipeline detection device. Background Art

[0002] A pressure pipeline is a part of a pipeline. A pipeline is used to transport, distribute, mix, separate, discharge, measure, control, and stop the flow of fluids. Pressure pipelines need to be detected during production to prevent defective pipelines from entering the market.

[0003] After retrieval, the invention with the patent publication number CN117990486B discloses a pressure pipeline detection device that can perform hydrostatic tests on different types of pipelines to measure the compressive capacity of the pipelines. By driving a rotating plate to rotate with a driving member, the pipeline to be detected can be moved into a water tank, enabling the interior of the pipeline to be quickly filled with water. When detecting a pipeline with a larger inner diameter, the time required to fill the pipeline with water can be reduced, improving the detection efficiency. Since existing buried pressure pipelines are not only subjected to the internal pressure generated by the medium inside the pipe but also the external pressure caused by the compacted backfill soil and the vehicles above, and when the external of the pressure pipeline is squeezed, the internal pressure will further increase, making the pressure pipeline prone to rupture. However, in the prior art, there is no link to simulate and test this phenomenon, making it difficult to detect the actual compressive performance of the pressure pipeline. To reasonably improve this problem, the present application proposes a pressure pipeline detection device. Summary of the Invention

Detailed implementation manners

[0031] In order to make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application.

[0032] As Figures 1 - 6 shown, a pressure pipeline detection device proposed in an embodiment of the present application includes:

[0033] A water storage tank 1, the cross-section of the water storage tank 1 is rectangular, and a support frame 2 is installed at the bottom;

[0034] Sliding plates 3, the number of which is two, are respectively slidably matched with both sides of the water storage tank 1. The two sliding plates 3 are symmetrically arranged and are slidably matched with the water storage tank 1 in the vertical direction. The two sliding plates 3 are connected by a connecting frame 4. The tops of the two sliding plates 3 are detachably connected to the bottom of the connecting frame 4 by a bolt assembly. A overlapping part 5 for fixing the pressure pipeline is provided at the bottom of the connecting frame4. The pressure pipeline can be laid on the overlapping part 5 to restrict its movement. When the connecting frame 4 slides downward and the water body quickly fills the pressure pipeline, the pressure pipeline is not easily separated from the connecting frame 4;

[0035] There are two plugging plates 6, which are respectively slidably matched with both ends of the connecting frame 4. The two plugging plates 6 are respectively arranged on the opposite sides of the overlapping part 5 and slide along the length direction of the connecting frame 4. Sealing blocks 7 are laid on the opposite sides of the two plugging plates 6. The sealing blocks 7 are rubber blocks. A water pump 8 is installed in the water storage tank 1. An inlet hole 9 is formed on one of the plugging plates 6, and the inlet hole 9 penetrates through the sealing block 7. The output end of the water pump 8 is communicated with the inlet hole 9. A driving assembly 10 is arranged on the top of the connecting frame 4. The two plugging plates 6 can be driven to slide through the driving assembly 10. When the water body fills the pressure pipeline, the two plugging plates 6 can be driven to slide relatively through the driving assembly 10. At this time, the two sealing blocks 7 respectively seal both ends of the pressure pipeline to seal the pressure pipeline. Subsequently, the water body in the water storage tank 1 can be pumped out by the water pump 8, and the water body is injected into the pressure pipeline from the inlet hole 9 to apply pressure to the inside of the pressure pipeline;

[0036] A pressure applying assembly 11 is arranged in the water storage tank 1. The outside of the pressure pipeline can be pressured through the pressure applying assembly 11, and then the external pressure received when the pressure pipeline is in use can be simulated through the pressure applying assembly 11;

[0037] A detection assembly 12 is arranged in the water storage tank 1. The internal and external pressures of the pressure pipeline can be detected through the water storage tank 1, and the actual pressure resistance performance of the pressure pipeline can be detected through the detection assembly 12;

[0038] A driving mechanism 13 is installed on the water storage tank 1. The connecting frame 4 can be driven to slide vertically through the driving mechanism 13;

[0039] During use, the pressure pipeline can be placed on the overlapping part 5, and then the connecting frame 4 is driven to slide downward through the driving mechanism 13. At this time, the pressure pipeline to be detected can be moved into the water tank, so that the inside of the pressure pipeline is quickly filled with water. When detecting a pressure pipeline with a larger inner diameter, the time required to fill the inside of the pressure pipeline with water can be reduced, and the detection efficiency can be effectively improved. Subsequently, the two plugging plates 6 can be driven to slide relatively through the driving assembly 10, and both ends of the pressure pipeline are respectively sealed by the two sealing blocks 7 to seal the pressure pipeline. The water body in the water storage tank 1 is pumped out by the water pump 8, and the water body is injected into the pressure pipeline from the inlet hole 9 to apply pressure to the inside of the pressure pipeline. Finally, the external pressure received when the pressure pipeline is in use can be simulated through the pressure applying assembly 11, and the actual pressure resistance performance of the pressure pipeline can be detected through the detection assembly 12;

[0040] Through the mutual cooperation of the water storage tank 1, the sliding plate 3, the connecting frame 4, the overlapping part 5, the plugging plate 6, the sealing block 7, the water pump 8, the inlet hole 9, the driving assembly 10, the pressure applying assembly 11, the detection assembly 12 and the driving mechanism 13 in this application, the external pressure received when the pressure pipeline is in use can be simulated and detected. Compared with the prior art, the detection of the actual pressure resistance ability of the pipeline in this application is more accurate.

[0041] As Figure 2 , Figure 3 and Figure 6 shown, in some embodiments, the overlapping portion 5 includes two brackets 501. The two ends of the two sliding plates 3 are respectively connected through the two brackets 501. The two brackets 501 are away from each other. The pressure pipeline is movably arranged on the tops of the two brackets 501. The two ends of the pressure pipeline can be respectively arranged on the two brackets 501, so that it is not easy to separate from the connecting frame 4.

[0042] As Figure 2 , Figure 3 and Figure 6 shown, in some embodiments, the bracket 501 is V-shaped, and the V-shaped opening of the bracket 501 faces the connecting frame 4. Such a design can effectively fix pressure pipelines with different diameters. The sealing block 7 is frustum-shaped. When the two plugging plates 6 move relative to each other, the ends of the two sealing blocks 7 can respectively insert into the pipe orifices of the pressure pipeline. As the sealing block 7 continuously penetrates, under the action of the conical surface on the sealing block 7, pressure pipelines with different diameters can all move to be coaxial with the sealing block 7.

[0043] As Figures 4 - 6 shown, in some embodiments, the pressing assembly 11 includes mounting blocks 1101 constructed on the inner walls of both sides of the water storage tank 1. The mounting blocks 1101 on both sides are symmetrically arranged and extend relatively. The tops of the mounting blocks 1101 are all slidably fitted with movable plates 1102. The movable plates 1102 are slidably fitted along the length direction of the mounting blocks 1101. Arc-shaped plates 1103 are provided at the opposite ends of the two movable plates 1102. Flexible pads 1104 are provided on the opposite sides of the two arc-shaped plates 1103. The flexible pads 1104 are located on the inner arcs of the arc-shaped plates 1103. The flexible pads 1104 can be in contact and overlap with the outer sides of the pressure pipeline. The two movable plates 1102 are in linkage cooperation with the sliding plate 3 through a linkage assembly 1105. After the sealing block 7 seals the pressure pipeline, the sliding plate 3 can be driven to continue sliding downward. Under the action of the linkage assembly 1105, the two movable plates 1102 can be driven to slide relatively. At this time, the two flexible pads 1104 can respectively contact the two sides of the pressure pipeline to apply an external pressure.

[0044] As Figures 4 - 6As shown, in some embodiments, the arc-shaped plate 1103 is hinged to the movable plate 1102, and the arc-shaped plate 1103 and the movable plate 1102 are connected by a torsion spring 1106. The fixed end of the torsion spring 1106 is connected to the movable plate 1102, and the movable end of the torsion spring 1106 is connected to the arc-shaped plate 1103. The two arc-shaped plates 1103 can be driven to flip upward by the torsion spring 1106. With such a design, in the normal state, the distance between the tops of the two arc-shaped plates 1103 is relatively large, facilitating the pressure pipeline to enter the space between the two arc-shaped plates 1103. When the pressure pipeline enters between the two arc-shaped plates 1103 and contacts the bottoms of the two arc-shaped plates 1103, the two arc-shaped plates 1103 can rotate along with the pressure pipeline.

[0045] As Figures 3 - 6 shown, in some embodiments, the linkage assembly 1105 includes two lead screws 11051 rotatably installed on the opposite inner walls of the water storage tank 1. The lead screws 11051 are perpendicular to the inner wall of the water storage tank 1, and a spur gear 11052 is coaxially connected to the outside of the lead screw 11051. Rack teeth 11053 are formed on the sliding plates 3, and the rack teeth 11053 mesh with the spur gear 11052. When the sliding plates 3 slide downward, the lead screws 11051 can be driven to rotate through the spur gear 11052 and the rack teeth 11053. Fixed blocks 11054 are formed at the bottoms of the movable plates 1102, and the fixed blocks 11054 are in threaded cooperation with the lead screws 11051. When the lead screws 11051 rotate, the movable plates 1102 can be driven to slide towards the pressure pipeline through the fixed blocks 11054.

[0046] As Figure 2 、 Figure 4 、 Figure 5 and Figure 6 shown, in some embodiments, the detection assembly 12 includes a display screen 1201 installed on the top of the connecting frame 4, and a first pressure sensor 1202 is installed on the other sealing plate 6. The first pressure sensor 1202 is a water pressure sensor. The end of the first pressure sensor 1202 penetrates through the sealing plate 6 and the sealing block 7, thereby enabling the detection of the water pressure inside the pressure pipeline. The arc-shaped plate 1103 and the flexible pad 1104 are connected to each other through a second pressure sensor 1203. The second pressure sensor 1203 is a plate-type pressure sensor, which can detect the pressure applied outside the pressure pipeline. Both the first pressure sensor 1202 and the second pressure sensor 1203 are electrically connected to the display screen 1201, and the internal and external pressures of the pressure pipeline are displayed on the display screen 1201 for easy observation.

[0047] As Figure 1As shown, in some embodiments, the driving assembly 10 includes a rotating rod 1001 rotatably mounted on the top of the connecting frame 4. The axis of the rotating rod 1001 extends along the length direction of the connecting frame 4. Both ends of the rotating rod 1001 threadedly penetrate through two plugging plates 6 respectively, and the thread directions at both ends of the rotating rod 1001 are opposite. When the rotating rod 1001 rotates, it can drive the two plugging plates 6 to slide relatively or away from each other. A first motor 1002 for driving the rotation of the rotating rod 1001 is mounted on the top of the connecting frame 4. The first motor 1002 is a hollow shaft motor, and the middle part of the rotating rod 1001 is connected to its hollow shaft.

[0048] As Figure 2 , Figure 4 and Figure 6 As shown, in some embodiments, the driving mechanism 13 includes a second motor 1301 mounted on the support frame 2. The second motor 1301 is a servo motor and is located at the bottom of the water storage tank 1. The sliding plate 3 includes an inner plate 301 and an outer plate 302 that are parallel to each other. The sliding plate 3 is in a U-shape, and their tops are connected to each other. An opening 16 for passing through the mounting block 1101 and the movable plate 1102 is formed on the inner plate 301. A rack 11053 is arranged in the opening 16. A threaded rod 1302 is rotatably mounted on the support frame 2. The threaded rod 1302 is vertical, and the threaded rod 1302 is connected to the output shaft of the second motor 1301 through a bevel gear assembly 1303. The bevel gear assembly 1303 includes two bevel gears, which are respectively mounted on the threaded rod 1302 and the output shaft of the second motor 1301, and the threaded rod 1302 is in threaded cooperation with one of the outer plates 302. When the second motor 1301 works, it can drive the threaded rod 1302 to rotate through the bevel gear assembly 1303, so as to drive the sliding plate 3 to drive the connecting frame 4 to slide.

[0049] As Figure 1 and Figure 6 As shown, in some embodiments, a distance sensor 14 is mounted at the bottom of the other outer plate 302. The distance sensor 14 is a high-precision distance sensor 14 and is electrically connected to the display screen 1201. A fixing plate 15 is constructed on the support frame 2. The distance sensor 14 is movably lapped with the fixing plate 15. Through the mutual cooperation of the distance sensor 14 and the fixing plate 15, the sliding distance of the connecting frame 4 can be accurately measured, so as to accurately control the moving distance of the movable plate 1102.
