[0004] Regarding the above related technologies, there are some deficiencies in this device. During actual use, the test position of the pressure vessel is located in a non - movable device. Once the vessel explodes during the test, the generated fragments will concentrate below the interior of the device. Due to the obstruction of mechanical components below the interior of the device, it increases the difficulty of cleaning after the accident and also affects the maintenance and safety of the equipment. Therefore, it is necessary to provide a pressure test device for pressure vessels to solve the above technical problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a pressure test device for pressure vessels to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A pressure test device for a pressure vessel, which includes:

[0008] A base plate and a pressure vessel, both sides of the top of the base plate are fixedly installed with vertical plates, sliding grooves are opened on the opposite sides of the two vertical plates, a fixed cavity is arranged inside the base plate, a threaded rod is rotatably installed inside the sliding groove, and the bottom end of the threaded rod sequentially penetrates the bottom of the inner wall of the sliding groove and the top of the base plate and extends into the fixed cavity to be rotatably connected with a bearing installed on the inner wall of the fixed cavity;

[0009] Adjusting blocks are sleeved on the outer walls of the two threaded rods, and the adjusting blocks are slidably connected to the sliding grooves.

[0028] Please refer to Figures 1-4 , an embodiment provided by the present utility model:

[0029] A pressure test device for a pressure-bearing container, which includes:

[0030] The substrate 1 and the pressure-bearing container 18 are provided. On both sides of the top of the substrate 1, vertical plates 2 are fixedly installed. Sliding grooves 8 are formed on the opposite sides of the two vertical plates 2. A fixed cavity 16 is arranged inside the substrate 1. A threaded rod 9 is rotatably installed inside the sliding groove 8. The bottom end of the threaded rod 9 sequentially penetrates the bottom of the inner wall of the sliding groove 8 and the top of the substrate 1 and extends into the fixed cavity 16, where it is rotatably connected to a bearing installed on the inner wall of the fixed cavity 16;

[0031] Adjusting blocks 14 are sleeved on the outer walls of the two threaded rods 9, and the adjusting blocks 14 are slidably connected to the sliding grooves 8. Connecting frames 3 are fixedly installed on the opposite sides of the two adjusting blocks 14. An explosion-proof box 10 is fixedly installed between the two connecting frames 3. A sealing mechanism 13 is arranged above the inside of the explosion-proof box 10. A driving mechanism is arranged inside the fixed cavity 16. An explosion-proof glass 12 is arranged on the front of the explosion-proof box 10. The setting of the explosion-proof glass 12 facilitates the staff to observe the situation inside the box through the explosion-proof glass 12. At the same time, the explosion-proof glass 12 can effectively prevent the fragments generated by explosion or impact from flying out of the box.

[0032] The sealing mechanism 13 includes an electric telescopic rod 7, and the electric telescopic rod 7 is fixedly installed on the top of the explosion-proof box 10. The driving end of the electric telescopic rod 7 penetrates the top of the explosion-proof box 10 and extends above the inside of the explosion-proof box 10. A pressing plate 20 is fixedly installed at the driving end of the electric telescopic rod 7. A pipe body 4 is fixedly inserted and installed on one side of the top of the pressing plate 20. The top end of the pipe body 4 penetrates the top of the inner wall of the explosion-proof box 10 and extends above the top of the explosion-proof box 10. The pipe body 4 is slidably connected to the explosion-proof box 10. A sealing gasket 19 is fixedly installed at the bottom of the pressing plate 20, and a pressure sensor 21 is fixedly installed at the bottom of the pressing plate 20.

[0033] In one embodiment, limit blocks 6 are fixedly installed above the opposite sides of the two vertical plates 2. Limit plates 5 are fixedly installed on both sides of the explosion-proof box 10. The limit blocks 6 are slidably connected to the limit plates 5 through the sliding grooves formed thereon, which improves the vertical movement stability of the explosion-proof box 10, and further enhances the connection stability between the explosion-proof box 10 and the vertical plates 2, which is beneficial to the stable use of the explosion-proof box 10.

[0034] In one preferred embodiment, the driving mechanism includes a worm 17, and the worm 17 is rotatably installed inside the fixed cavity 16. Worms 11 are fixedly installed on the outer walls of the bottom ends of the two threaded rods 9, and the worms 11 are meshed with the worm 17. A motor 15 is fixedly installed on one side of the substrate 1. The driving end of the motor 15 penetrates one side of the substrate 1 and extends into the fixed cavity 16 and is fixedly connected to one end of the worm 17, realizing the vertical movement of the explosion-proof box 10 in a mechanical driving manner.

[0035] In one embodiment, a plurality of stabilizing blocks 23 are fixedly installed at the bottom of the explosion-proof box 10. Corresponding slots 22 are provided at the top of the substrate 1 in terms of position and quantity, and the slots 22 are snap-connected to the stabilizing blocks 23, improving the firmness of the explosion-proof box 10 closed on the top of the substrate 1.

[0036] In one preferred embodiment, a threaded hole adapted to the threaded rod 9 is provided at the top of the adjusting block 14, and the adjusting block 14 is threadedly connected to the threaded rod 9 through the threaded hole provided at its top.

[0037] The working principle of the present utility model is as follows: All electrical components mentioned in the text are electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer for control, and the existing publicly disclosed power connection technology will not be elaborated in the text. During use, first control the motor 15 to start working. The driving end of the motor 15 drives the worm 17 to rotate. Through the meshing of the worm 17 and the worm wheel 11, the two worm wheels 11 rotate synchronously. The rotation of the worm wheel 11 drives the threaded rod 9 to rotate. Through the threaded transmission between the threaded rod 9 and the adjusting block 14, and the sliding relationship between the adjusting block 14 and the sliding groove 8, the two adjusting blocks 14 stably move vertically synchronously. The movement of the adjusting block 14 drives the explosion-proof box 10 to move through the connecting frame 3, so that the explosion-proof box 10 originally closed on the top of the substrate 1 moves up to a certain height. Then directly place the pressure-bearing container 18 on the top of the substrate 1 directly below the explosion-proof box 10. Subsequently, control the explosion-proof box 10 to move downward and close on the top of the substrate 1. At the same time, control the electric telescopic rod 7 to start working. The driving end of the electric telescopic rod 7 drives the pressing plate 20 to move vertically above the inside of the explosion-proof box 10, so that the pressing plate 20 moves downward and directly presses on the top opening of the pressure-bearing container 18. And through the setting of the sealing gasket 19 at the bottom of the pressing plate 20, the sealing effect of the pressing plate 20 on the top opening of the pressure-bearing container 18 is ensured, avoiding air leakage during subsequent experiments. At this time, connect the external end of the pipe body 4 outside the explosion-proof box 10 to a high-pressure pump, and conduct a pressure test on the pressure-bearing container 18 through the end of the pipe body 4 inside the pressure-bearing container 18. After the test is qualified, directly control the explosion-proof box 10 to move up, so that the explosion-proof box 10 loses the sealing effect on the pressure-bearing container 18, and then the pressure-bearing container 18 on the top of the substrate 1 can be directly taken away. If there is a problem with the quality of the pressure-bearing container 18 and it explodes during the test, the generated fragments will be blocked by the structure of the explosion-proof box 10 and restricted inside the explosion-proof box 10. This design effectively prevents the influence of the fragments on the external staff of the device, thereby improving the operation safety. The generated fragments will eventually concentrate in the top area of the substrate 1 inside the explosion-proof box 10. For the convenience of later cleaning, the explosion-proof box 10 is designed with a function of vertical movement. By controlling the vertical movement of the explosion-proof box 10, the explosion-proof box 10 is lifted upward, so that the top area of the substrate 1 is exposed. Since there is no obstruction of any mechanical components on the top of the substrate 1, the staff can clean the fragments on the top very conveniently and quickly. This design reduces the cleaning difficulty after the accident and ensures the normal maintenance and operation safety of the equipment.
