DETAILED DESCRIPTION

[0031] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0032] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0033] Embodiment 1:

[0034] A pipeline pressure test device, such as Figures 1 to 7As shown, it includes a water pool 1 and a mounting portion and a pressure-applying portion for fixing a pipeline assembly, a wave-making portion is installed at one end of the water pool 1, and the pressure-applying portion includes a hydraulic cylinder 9 and a top plate 12, the hydraulic cylinder 9 is fixed to the inner wall of the bottom of the water pool 1 by bolts, and the top plate 12 is fixedly connected to the output end of the hydraulic cylinder 9, a connecting plate 21 is welded to the bottom of the top plate 12, and an elastic member is slidably connected to a through hole opened on the surface of the connecting plate 21, and a gate plate 15 is fixed to one end of the elastic member, and a slideway 16 is welded to the outer wall of one side of the gate plate 15, a rectangular plate 19 is fixed to the inner wall of the bottom of the water pool 1 by bolts, and an intermediate rod 10 is slidably connected to the through hole opened on the surface of the rectangular plate 19, and a bracket 17 is welded to one end of the intermediate rod 10, and a support roller 18 is rotatably connected to the inner wall of the bracket 17, and a slide plate 20 is fixed to the other end of the intermediate rod 10 by bolts, and the slide plate 20 and the slideway 16 are slidably connected;

[0035] After the pipe assembly is fixed by the mounting part, a certain amount of water is injected into the pool 1. When the pipe assembly needs to be subjected to an overall pressure test under a dynamic environment, the hydraulic cylinder 9 is used to drive the connection plate 21 to rise. During this process, the gate plate 15 moves synchronously under the connection of the elastic member until the bottom of the gate plate 15 moves to the top of the pool 1. The wave-making part is used to impact the water in the pool 1, so that the water forms waves after being impacted to impact the pipe assembly immersed in the water. After repeated tests for several times, it is observed whether there is water leakage at the connection of the pipe assembly, and the pressure resistance performance of the pipe assembly from the outside is tested. This test method can simulate the impact of water flow on the pipe assembly when the pipe assembly is laid on the seabed or riverbed;

[0036] When it is necessary to perform a local pressure test on the pipeline assembly under a dynamic environment, the hydraulic cylinder 9 is used to indirectly drive the gate plate 15 to move downward. When the bottom of the gate plate 15 moves to the inner wall of the bottom of the pool 1, the gate plate 15 is stopped from being driven to move, and the water between the gate plate 15 and the pipeline assembly is drained. During the movement of the gate plate 15, the slide 16 slides along the slide plate 20. When the local pressure test is performed, when the wave-making part generates water waves, the gate plate 15 separates the wave-making part and the pipeline assembly, so that the water waves impact the gate plate 15. After the gate plate 15 is impacted, the elastic member is deformed. The force transmission property is used to make the elastic member finally indirectly drive the support roller 18 to perform an impact test on the local position on the pipeline assembly during the lateral movement. After repeated tests for many times, the connection of the pipeline assembly is observed in the same way to see if there is any leakage, so as to detect the local pressure test performance of the pipeline assembly. This detection method can simulate the impact of hard objects such as sand and gravel on the pipeline assembly on the pipeline assembly after the pipeline assembly is laid.

[0037] The elastic member includes a side plate 22 and a pressure sensor 23, the pressure sensor 23 is fixed to the outer wall of one side of the connecting plate 21 by screws, and the side plate 22 is fixed to the outer wall of one side of the pressure sensor 23 by screws, and a through hole opened on the surface of the side plate 22 is slidably connected with a T-shaped rod 14, and a spring 13 is clamped between the inner wall of one side of the T-shaped rod 14 and the outer wall of one side of the side plate 22, and the outer wall of the other side of the T-shaped rod 14 is fixedly connected to the gate 15;

[0038] When it is necessary to perform a local pressure test on the pipeline assembly in a dynamic environment, when the water waves generated by the wave-making part impact the gate 15, the spring 13 is deformed under the action of the impact force, thereby indirectly driving the support roller 18 to perform a local pressure test on the surface of the pipeline assembly during the lateral movement. By providing a pressure sensor 23, the instantaneous impact force on the surface of the pipeline assembly can be indirectly monitored, and the pressure resistance performance of the pipeline assembly can be judged by monitoring the value of the pressure sensor 23.

[0039] The wave-making part includes an electric cylinder 7 and a wave-making board 8. The electric cylinder 7 is fixed to the outer wall of one side of the pool 1 by bolts, and the wave-making board 8 is fixed to the output end of the electric cylinder 7 by pins.

[0040] When the electric cylinder 7 drives the wave-making board 8 to move quickly, the wave-making board 8 is used to impact the water in the pool 1, so that water waves are generated after the impact, and the impact force of the waves is used to perform a pressure test on the pipeline components.

[0041] The mounting portion includes a conical block 24 and a water inlet pipe 35, the water inlet pipe 35 is embedded in the outer wall of one side of the pool 1, and the conical block 24 and one end of the water inlet pipe 35 are rotatably connected through a joint, the mounting portion also includes a rotating column 28 and a limiting block 37, the rotating column 28 is rotatably connected to the outer wall of the other side of the pool 1, and a coil spring 27 is clamped between the rotating column 28 and the pool 1, and the limiting block 37 is welded to the outer wall of the rotating column 28, and the rotating column 28 and the outer wall of the limiting block 37 are slidably connected with a driving disk 41, and a hydraulic cylinder 29 is fixed to the outer wall of one side of the pool 1 by bolts, and the output end of the hydraulic cylinder 29 and the driving disk 41 are fixedly connected, the outer wall of one side of the driving disk 41 is rotatably connected with a rotating disk 38, and a moving rod 40 is welded to the outer wall of one side of the rotating disk 38, and one end of the moving rod 40 is fixed with a conical block 26 by screws;

[0042] When fixing the pipeline assembly, the hydraulic cylinder 1 29 can be used to drive the driving disk 41, the turntable 38 and the conical block 26 to move horizontally, adjust the straight-line distance between the conical block 26 and the conical block 1 24, and adapt to pipeline assemblies of different lengths.

[0043] The pipeline assembly includes two sets of pipeline bodies 25, and the two sets of pipeline bodies 25 are fixedly connected by bolts and nuts;

[0044] After the two pipeline bodies 25 are fixed, the two fixed pipeline bodies 25 are placed between the conical block 1 24 and the conical block 2 26 , and the conical block 1 24 and the conical block 2 26 are used to clamp and fix the pipeline bodies 25 .

[0045] A pressure gauge 36 is installed on the outer wall of the water inlet pipe 35, and a valve 2 34 is fixed to one end of the water inlet pipe 35 by bolts, and a tee pipe 33 is fixed to one end of the valve 2 34, and a valve 1 31 is fixed to the top of the tee pipe 33 by bolts, and the valve 1 31 and the pool 1 are connected by a connecting pipe 30, and a water pump 32 is fixed to the side of the tee pipe 33 by bolts;

[0046] When valve one 31 is opened and valve two 34 is closed, water can be injected into the pool 1 through the connecting pipe 30 by using the water pump 32. When valve one 31 is closed and valve two 34 is opened, water can be input into the pipeline assembly by using the water pump 32. The water pressure in the pipeline assembly is monitored by the pressure gauge 36, and then the pressure resistance performance of the pipeline assembly is tested from the inside.

[0047] One end of the T-shaped rod 14 is rotatably connected to a rolling ball 11, and the rolling ball 11 and the wave-making board 8 are used in conjunction with each other;

[0048] When it is necessary to perform a pressure test on the pipeline assembly in a static environment, ensure that the inside of the water pool 1 is in a water-free state. When the electric cylinder 7 is used to drive the wave-making plate 8 to move to fit the surface of the ball 11, the wave-making plate 8 is used to push the ball 11, so that the support roller 18 is indirectly pushed and moved to the outer wall of the pipeline assembly, thereby performing a pressure test on the outer wall of the pipeline assembly in a static environment.

[0049] A drain valve 42 is fixed to one end of the water pool 1 by bolts;

[0050] The water in the pool 1 can be drained by providing a drain valve 42 .

[0051] When using this embodiment, firstly, the pipe assembly is fixed by the mounting part, then the valve 1 31 is opened and the valve 2 34 is closed, and a certain amount of water is injected into the water pool 1 by the water pump 32. When the water covers the pipe assembly, the pipe assembly is first subjected to an overall pressure resistance test under a dynamic environment, and then the water in the water pool 1 is impacted by the wave-making part, so that the water forms water waves after being impacted to impact the pipe assembly immersed in the water, and after repeated tests for several times, whether there is water leakage at the connection of the pipe assembly is observed;

[0052] When the pipeline assembly is subjected to a local pressure test under a dynamic environment, the water between the gate plate 15 and the pipeline assembly is drained. When the wave-making part generates water waves, the gate plate 15 separates the wave-making part and the pipeline assembly, so that the water waves impact the gate plate 15. After the gate plate 15 is impacted, the spring 13 is deformed. By utilizing the force transmission property, the elastic member finally indirectly drives the support roller 18 to perform an impact test on a local position on the pipeline assembly during the lateral movement. After repeated tests for many times, observe whether there is water leakage at the connection of the pipeline assembly in the same way;

[0053] When it is necessary to perform a pressure test on the pipeline assembly in a static environment, ensure that the inside of the pool 1 is in a water-free state. When the electric cylinder 7 is used to drive the wave-making board 8 to move to fit the surface of the ball 11, the wave-making board 8 is used to push the ball 11, so that the support roller 18 is indirectly pushed and moved to the outer wall of the pipeline assembly, thereby performing a pressure test on the outer wall of the pipeline assembly in a static environment;

[0054] After the above test items are completed, when valve 1 31 is closed and the water inlet pipe 35 is opened, water can be input into the pipeline assembly using the water pump 32, and the water pressure in the pipeline assembly is monitored by the pressure gauge 36, and then the pressure resistance performance of the pipeline assembly is tested from the inside.

[0055] Embodiment 2:

[0056] A pipeline pressure test device, such as Figures 1 to 7 As shown, in order to maintain the comprehensiveness of the test, this embodiment makes the following supplements on the basis of embodiment 1: the top outer wall of the pool 1 is fixed with a support plate 3 by bolts, and a pulley rod 4 is rotatably connected between the two support plates 3, a connecting plate 5 is fixed with a bolt on one side outer wall of the support plate 3, and a pulley body 6 is rotatably connected to the outer wall of one side of the connecting plate 5, a reel 39 is fixed with a screw on one end of the rotating column 28, a steel wire rope 2 is wound around the circumferential outer wall of the reel 39, and the end of the steel wire rope 2 away from the reel 39 is fixed to the top outer wall of the top plate 12, and the steel wire rope 2 is guided by the pulley rod 4 and the pulley body 6;

[0057] When the pipeline assembly is subjected to an overall pressure test in a dynamic environment, in order to ensure that the water waves can perform pressure tests on different parts of the pipeline assembly in the circumferential direction, the transmission effect of the steel wire rope 2 is used to drive the reel 39 to rotate when the gate plate 15 moves to the top of the pool 1 and then continues to move, and the torsion of the coil spring 27 is used to keep the reel 39 always taut. The reel 39 drives the pipeline assembly to rotate synchronously during the rotation process, thereby adjusting the position of direct contact between the pipeline assembly and the water waves in the lateral direction;

[0058] When a local pressure test is performed on the pipeline assembly in a static environment, when the support roller 18 moves to fit the circumferential outer wall of the pipeline assembly, the ball 11 is used to make the electric cylinder 7 apply a lateral force to the support roller 18. During the process of the gate 15 moving in the vertical direction, the turntable 38 is driven to rotate by the wire rope 2, so that the support roller 18 applies pressure while the pipeline assembly keeps rotating, so that different positions in the circumferential direction of the pipeline assembly can be subjected to pressure tests in a static environment.

Any modification, equivalent substitution and improvement made by any technician familiar with the field within the technical scope disclosed by the present invention in combination with the prior art or public common sense, within the spirit and principle of the present invention, shall be covered by the protection scope of the present invention.
