DETAILED DESCRIPTION

[0018] The principles and characteristics of the utility model are described below in combination with the drawings, and the examples are only used to explain the utility model and not used to limit the scope of the utility model.

[0019] Example 1

[0021] The drainage mechanism 3 includes a water tank 31 located at one end of the top of the top plate 4. A first water pump 33 is located at one end of the top of the water tank 31. A first water pipe 32, penetrating a circular hole at the top of the water tank 31, is located at the input end of the first water pump 33. A second water pipe 34 is located at the output end of the first water pump 33. A rotary joint 35 is connected to the bottom of the second water pipe 34. A connecting pipe 36, rotatably connected to the bottom of the rotary joint 35 via a bearing, is rotatably connected to the inside of the circular hole at the top of the top plate 4. A fixing plate 8 is located at the lower end of the connecting pipe 36. The bottom of the connecting pipe 36 is connected to... The bottom of the hose 37 and the fixed plate 8 is provided with an electric push rod 9. The output end of the electric push rod 9 is provided with a pressure plate 10. The bottom port of the hose 37 passes through the pressure plate 10. It also includes a baffle 312 that is vertically installed on the top of the base plate 1. A second water pump 310 is provided on one side of the baffle 312. The input end of the second water pump 310 is provided with a fourth water pipe 39. The top of the fourth water pipe 39 is connected to a third water pipe 38 that is connected to the through hole at the top of the base plate 1. The output end of the second water pump 310 is provided with a fifth water pipe 311 that is connected to the water tank 31.

[0022] When a pressure pipeline needs to be tested, the pressure pipeline is placed vertically on the rotating plate 6 and clamped and fixed by the pressure plate 10. The first water pump 33 is started, and the first water pump 33 draws water from the water tank 31 through the first water pipe 32 and sends it to the connecting pipe 36 through the second water pipe 34 and the rotary joint 35. The water in the connecting pipe 36 enters the pressure pipeline through the hose 37 and the pressure plate 10. By observing whether there is water flowing out of the outside of the pressure pipeline, a sealing test is performed on the pressure pipeline. After the test is completed, the pressure plate 10 is reset. The pressure pipe is removed from the rotating plate 6. As the pressure pipe leaves the rotating plate 6, the water flows around the rotating plate 6 and is blocked by the baffle 312 on the bottom plate 1. It then enters the third water pipe 38 through the through hole at the top of the bottom plate 1. The second water pump 310 is started, and the second water pump 310 pumps the water in the third water pipe 38 into the fifth water pipe 311 through the fourth water pipe 39. The water is then sent to the water tank 31 through the fifth water pipe 311, which facilitates the recycling of water and prevents water from flowing around the staff after the pressure pipe is tested.

[0023] In practice, the pressure pipe is placed vertically on top of the rotating plate 6. Rubber pads are provided on the opposite side of the pressure plate 10 and the rotating plate 6 to increase the sealing performance when testing the pressure pipe. The pressure plate 10 and the rotating plate 6 abut against the top and bottom of the pressure pipe respectively, so that the pressure pipe forms a sealed space. The sealing performance of the pressure pipe is tested by pumping water into the pressure pipe.
