[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Please see Figures 1 to 8This utility model provides a technical solution: a pipeline pressure testing device, including a base plate 1, a pressure testing mechanism, and a support and fixing mechanism 6. The pressure testing mechanism includes a first adjusting plate 4, a second adjusting plate 5, a connecting pipe 7, and a conical rubber plug 8. The first adjusting plate 4 and the second adjusting plate 5 are symmetrically arranged at the top of both ends of the base plate 1 via a moving mechanism. The connecting pipe 7 is fixedly installed inside the top ends of the first adjusting plate 4 and the second adjusting plate 5. The conical rubber plug 8 is fixedly installed on the outside of one end of the connecting pipe 7 and is fixedly connected to the side walls of the first adjusting plate 4 and the second adjusting plate 5. The support and fixing mechanism 6 includes a fixing plate 11, an adjusting mechanism 12, a lifting plate 13, and a movable elastic plate. 14. The fixed plates 11 are symmetrically fixedly installed on the front and rear sides of the top of the base plate 1. The lifting plate 13 is slidably installed between the fixed plates 11 on the front and rear sides through the adjusting mechanism 12. The movable elastic plate 14 is symmetrically installed on the top sides of the lifting plate 13 through the torsion spring shaft. The pipe 10 is clamped between the conical rubber plugs 8 on both sides. The conical rubber plugs 8 on both sides are synchronously adjusted by the moving mechanism to facilitate the sealing of both ends of the pipe 10 by the conical rubber plugs 8 on both sides, thereby ensuring the sealing state between the device and the two ends of the pipe 10. This facilitates the subsequent pressure test of the pipe 10 by the cooperation of the connecting pipe 7, pressure sensor 9 and conical rubber plugs 8, thus improving the practicality of the device.

[0025] In this embodiment, the moving mechanism includes a first sliding groove 2 and a bidirectional screw 3. The first sliding groove 2 is symmetrically opened on both sides of the top of the base plate 1. The bidirectional screw 3 is rotatably installed inside the first sliding groove 2 and the base plate 1. A handwheel is fixedly installed at one end of the bidirectional screw 3 corresponding to the outer side of the base plate 1. The bottom ends of the first adjusting plate 4 and the second adjusting plate 5 are limited and slidably installed inside the first sliding groove 2 on both sides. The bottom ends of the first adjusting plate 4 and the second adjusting plate 5 are screwed to the outer sides of both ends of the bidirectional screw 3 through screw holes opened inside them. The first sliding groove 2 and the bidirectional screw 3 can limit the first adjusting plate 4 and the second adjusting plate 5, and can also rotate the handwheel and the bidirectional screw 3 to facilitate relative movement or movement to both sides of the first adjusting plate 4 and the second adjusting plate 5, which is convenient for subsequent clamping, fixing and separation of the pipe 10.

[0026] In this embodiment, pressure sensors 9 are fixedly installed at the other end of the connecting pipe 7 on the outer side of the first adjusting plate 4 and the second adjusting plate 5. The axes of the connecting pipe 7 and the conical rubber plug 8 on both sides are on the same horizontal straight line, which can ensure that the conical rubber plug 8 on both sides squeezes and seals the two ends of the pipe 10, thereby improving the sealing between the pipe 10 and the device, and facilitating the detection of pressure changes at both ends of the pipe 10 by the pressure sensors 9 at both ends.

[0027] In this embodiment, an arc-shaped surface is provided on the side wall of the top of the fixed plate 11. The arc-shaped surface is located on the top of the lifting plate 13. A limiting mechanism is provided between the two ends of the lifting plate 13 and the fixed plate 11. The limiting mechanism includes a second slide groove 15 and a slider 16. The slider 16 is symmetrically fixedly installed at both ends of the lifting plate 13. The second slide groove 15 is symmetrically opened on the inner walls of the two fixed plates 11. The slider 16 is slidably installed inside the second slide groove 15. A pad 17 is fixedly provided between the top of the lifting plate 13 and the two movable elastic plates 14. An arc-shaped groove is opened on the top of the pad 17. The pipe 10 is clamped and installed between the top of the pad 17 and the movable elastic plate 14. The adjusting mechanism 12 includes a fixed cylinder 18 and an adjusting screw 19. The fixed cylinder 18 is fixedly installed on the top of the base plate 1. The center position corresponds to the space between the two fixed plates 11. The adjusting screw 19 is screwed into the inside of the fixed cylinder 18. The adjusting screw 19 is limited to rotate and installed at the bottom middle position of the lifting plate 13. A fixing ring 20 is fixedly installed on the outer side of the upper end of the adjusting screw 19. By rotating and adjusting the fixing ring 20 and the adjusting screw 19, the lifting plate 13 can be adjusted to rise. The second sliding groove 15 and the slider 16 can support the lifting plate 13, which can improve the stability of the lifting plate 13. At the same time, the lifting plate 13 can drive the pad block 17 and the movable elastic plate 14 to rise, which can facilitate the support of the middle part of the pipe 10. The top of the fixed plate 11 can squeeze the movable elastic plate 14, so that the movable elastic plate 14 can rotate and tilt towards the position of the pipe 10, which can facilitate the clamping of the pipe 10, thereby improving the stability of the pipe 10.

[0028] When using this pipeline pressure testing device, the section of pipeline 10 to be tested is placed on top of the lifting plate 13 and the pad 17, inside the arc-shaped groove. The diameter of the pipeline 10 is smaller than the maximum distance between the two movable elastic plates 14. Rotating the fixing ring 20 and the adjusting screw 19 causes the lifting plate 13, the pad 17, and the movable elastic plate 14 to rise, facilitating the adjustment of the height of the pipeline 10 via the lifting plate 13 and the pad 17. During the rising process of the movable elastic plate 14, it can interact with the arc-shaped surface on the fixing plate 11 and squeeze the movable elastic plate 14, causing the movable elastic plate 14 to rotate and move closer to the pipeline 10, facilitating the compression and fixation of the pipeline 10, and improving the stability of the pipeline 10. This ensures that both ends of the pipeline 10 are opposite to the conical rubber blocks 8 on both sides. Rotating the handwheel and the double-acting screw 3 allows for the adjustment of the first adjustment on both sides. The first adjusting plate 4 and the second adjusting plate 5 move synchronously and adjust each other. The first adjusting plate 4 and the second adjusting plate 5 move relative to each other, and the first adjusting plate 4 and the second adjusting plate 5 simultaneously drive the connecting pipe 7 and the conical rubber plug 8 to move closer to each other and contact the two ends of the pipe 10. This allows the conical rubber plug 8 to be inserted into the interior of the two ends of the pipe 10, facilitating the compression and sealing of the two ends of the pipe 10 through the cooperation of the first adjusting plate 4, the second adjusting plate 5 and the conical rubber plug 8, so that the two ends of the pipe 10 are in a sealed state. Valves are installed at both ends of the connecting pipe 7 on both sides. The outlet of the booster pump or other equipment is fixedly connected to the connecting pipe 7 on one side, and water is supplied to the interior of the pipe 10 through the connecting pipe 7. The cooperation of the connecting pipe 7 and the pressure sensor 9 facilitates pressure testing of the pipe 10, which improves the practicality of the device. The pressure sensor 9 is a TXY general-purpose 2088 pressure transmitter.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
