Description

Technical Field

[0001] This utility model relates to the field of water conservancy construction technology, specifically to a pipeline connection testing device for water conservancy and hydropower construction. Background Technology

[0002] During the construction of water conservancy projects, many gases or liquids need to be transported through pipelines. These pipelines are mainly divided into above-ground pipelines and underground pipelines. Above-ground pipelines are usually connected by fastening the flanges at the ends of the two pipelines with bolts and gaskets to seal them. However, for underground pipelines, because the flange diameter is larger and underground maintenance is inconvenient, the two pipelines are usually directly welded. Due to welding process and impurities, pipeline welding may produce certain gaps, pores, or cracks. Therefore, after pipeline welding, flaw detection is required to ensure integrity.

[0003] For example, a pipeline connection inspection device for water conservancy construction, disclosed in CN116593094B, includes an inspection cover fitted at the connection point of two pipeline bodies. The inspection cover consists of two C-shaped mounting covers, with their opposite ends connected by multiple sets of mounting components. A C-shaped partition is fixed inside each C-shaped mounting cover, forming a first air chamber and a second air chamber under the division effect of the partition. This pipeline connection inspection device for water conservancy construction, through the cooperation of the inflation component and the marking component, facilitates rapid and effective detection and judgment of the sealing condition of the two pipeline connections during the inspection process. Simultaneously, it automatically marks the locations of leaks at the pipeline connection, facilitating repair operations at any abnormal locations detected after the inspection.

[0004] The aforementioned patent proposes that by using the vent at the connection point, the gas rushing into the first air chamber continuously enters the detection chamber. Through the cooperation of the transmission component and the second connecting component, a marking pen is used to draw lines on the surface of the C-shaped mounting cover to automatically mark the location of the leak at the pipe connection point. However, in actual use, this structure is quite complex, and the marking component is difficult to remove. Over time, this will cause damage to the marking component and affect the subsequent detection results.

[0005] Therefore, we propose a pipeline connection testing device for water conservancy and hydropower construction to solve the problems mentioned above. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: Please refer to Figures 1-3 A pipeline connection testing device for water conservancy and hydropower construction includes a connecting pipe A1 and a connecting pipe B2 set at one end of the connecting pipe A1, and a connecting component 3 is installed between the connecting pipe A1 and the connecting pipe B2.

[0026] The connecting pipe A1 includes a pipe body A11 and a bent insert A14 installed at one end of the pipe body A11. A rubber layer A15 is installed on the outer surface of the bent insert A14.

[0027] The connecting pipe B2 includes a pipe body B21 and a bent insert B24 installed at one end of the pipe body B21. A rubber layer B25 is installed on the outer surface of the bent insert B24.

[0028] The connecting component 3 includes an installation tube 31, with a connecting ring C33 and a connecting ring D34 installed at both ends of the installation tube 31. Bending blocks 36 are installed on the inner walls of the connecting ring C33 on both sides of the installation tube 31, and the installation positions of the bending blocks 36 inside the connecting ring C33 and the connecting ring D34 are staggered. The installation positions of the bending inserts A14 and B24 are also staggered. The bending insert A14 can be inserted between the bending blocks 36 on one side, and the bending insert B24 can be inserted between the bending blocks 36 on the other side. The rubber layers A15 and B25 are deformed by compression, thus sealing the connection between the connecting tube A1 and the connecting component 3 and the connecting tube B2 and the connecting component 3.

[0029] The mounting tube 31 has an inner ring groove 32 inside its body, and the inner ring groove 32 penetrates the top end of the mounting tube 31. Both the top and bottom ends of the mounting tube 31 have operating holes 37, which communicate with the interior of the inner ring groove 32.

[0030] A connecting ring A12 is installed on the outer surface of the tube body A11 and on the side near the bent insert A14. A threaded hole A13 is opened through the outer side of the connecting ring A12.

[0031] A connecting ring B22 is installed on the outer surface of the tube body B21 and on the side near the connecting ring B22. A threaded hole B23 is opened through the outer side of the connecting ring B22.

[0032] The outer surface of the inner ring groove 32 is provided with a threaded hole C35. The bottom and top ends of the mounting tube 31 are provided with operating holes 37. The threaded hole C35 is internally connected with a bolt 4. The threaded holes C35 of the connecting ring C33 and the connecting ring D34 are aligned with the threaded holes A13 and B23 respectively. The bolt 4 is used to connect the connecting tube A1 and the connecting tube B2 to the connecting ring C33 and the connecting ring D34 respectively.

[0033] In this embodiment: Bending blocks A14 and B24 are respectively installed at one end of pipe body A11 and pipe body B21. Connecting ring A12 and threaded hole B23 pass through bending blocks A14 and B24 respectively, and are installed on the outside of pipe body A11 and pipe body B21. Pipe body A11 and connecting ring A12 are respectively installed at one end of connecting ring C33 and connecting ring D34. Because the bending blocks 36 installed inside connecting ring C33 and connecting ring D34 are staggered, the positions of bending blocks A14 and B24 installed at one end of pipe body A11 and pipe body B21 are also staggered. Bending block A14, carrying rubber layer A15, is inserted between the threaded holes C35 inside a set of connecting rings C33, and bending block B24, carrying rubber layer B25, is inserted into another... Between the threaded holes C35 on the inner side of the connecting ring C33, threaded holes A13 and B23 are aligned with the threaded holes C35 on the outer surfaces of the connecting ring C33 and the connecting ring D34, respectively. Multiple sets of bolts 4 are threaded into the interior of the threaded holes C35 and B23 and C35 and A13, respectively. That is, the bolts 4 are used to connect the two ends of the connecting member 3 to one end of the connecting pipe A1 and the connecting pipe B2, respectively, to complete the connection between the pipes. As the bolts 4 rotate, the connecting rings B22 and A12 move closer to one side of the connecting ring C33, causing the bent inserts B24 and A14 to press the rubber layer B25 towards one side of the inner ring groove 32, thus sealing the connection between the mounting pipe 31 and the bent inserts B24 and A14.

[0034] Example 2: This example is an improvement upon Example 1. For details, please refer to [link / reference]. Figures 2-4 An installation cylinder 321 is installed inside the inner ring groove 32. The top of the installation cylinder 321 has an opening 322. An inverted T-shaped rod 323 is slidably installed inside the installation cylinder 321. A connecting block 324 is installed at the top of the inverted T-shaped rod 323. A rubber pad 325 is installed at the top of the connecting block 324. A compression spring 326 is installed at the bottom of the installation cylinder 321 and between the bottom of the inverted T-shaped rod 323. After the external thrust disappears, the compression spring 326 uses its own restoring force to push the inverted T-shaped rod 323, the connecting block 324 and the rubber pad 325 upward. The rubber pad 325 enters the interior of the operating hole 37 to prevent external substances from entering the interior of the inner ring groove 32. The rubber pad 325 corresponds to the operating hole 37.

[0035] In this embodiment: When inspecting the pipe connection, the water pipe can be inserted into the operating hole 37 and the rubber pad 325 can be pressed down. The rubber pad 325 moves down from the inside of the operating hole 37, and the inverted T-shaped rod 323 is pressed down through the connecting block 324, which applies force to the compression spring 326, causing it to deform. The water in the water pipe flows into the inner ring groove 32. Since part of the inner ring groove 32 is not blocked by the bending block 36, when the connecting pipe A1 and the connecting pipe B2 are not tightly connected to the connecting member 3, the water will overflow from the unblocked inner ring groove 32. At this time, the connection can be inspected. After the inspection is completed, the operator can insert the bottom end of the installation pipe 31 into the operating hole 37 to facilitate the water in the inner ring groove 32 to flow out.

[0036] Working principle: Bolt 4 is used to connect the two ends of the connecting member 3 to one end of the connecting pipe A1 and the connecting pipe B2 respectively. The bent insert block B24 and the bent insert block A14 squeeze the rubber layer B25 towards one side of the inner ring groove 32 to seal the connection between the installation pipe 31 and the bent insert block B24 and the bent insert block A14. The water pipe is inserted into the operating hole 37, and the water in the water pipe is discharged into the inner ring groove 32. When the connecting pipe A1 and the connecting pipe B2 are not tightly connected to the connecting member 3, the water will overflow from the part of the inner ring groove 32 that is not blocked. Conversely, when the connecting pipe A1 and the connecting pipe B2 are tightly connected to the connecting member 3, the test is completed.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
