Description

Technical Field

[0001] The present disclosure relates to the technical field of pipeline detection, and in particular to a pressure pipeline detection device. Background Art

[0002] When compressing hydrogen, the pressure pipeline needs to be strictly inspected. If it is not inspected in time, an explosion may easily occur if a leak occurs. Therefore, the safety of the pressure pipeline is extremely important, and the inspection of the pressure pipeline is also extremely important. Due to the high pressure in the pipeline, it is easy to cause uneven pressure stress in various parts of the pipeline, and because the materials in various parts of the pipeline are not exactly the same, it is easy to cause expansion in different parts of the pipeline that is not easy to see with the naked eye. It needs to be inspected by detection equipment. The existing pressure pipeline measuring equipment is mostly an integrated design when in use, which is relatively bulky and very inconvenient to carry. It is not obvious enough to observe during inspection, resulting in low efficiency.

[0003] Current monitoring devices lack an alarm mechanism and a clamping assembly that can fit tightly against the pipe surface, which results in inaccurate detection results. At the same time, when the pressure is too high, an alarm cannot be issued in time to remind the detection personnel.

[0004] The existing disclosed portable pressure pipe detection device solution is convenient for picking up and carrying by providing a first detection ring and a second detection ring which can be placed separately from the first detection ring. The first detection ring and the second detection ring can be respectively sleeved on the outside of the pressure pipe body for fixing. By providing a clamping mechanism, the clamping mechanism can be evenly attached to the outside of the pressure pipe body, and the expansion condition of the outside of the pipe can be effectively detected, which is convenient for use. However, the alarm device of the device cannot send out an alarm in time to remind the detection personnel when the pressure is too high. Utility Model Content

[0039] The working steps of the pressure pipeline detection device of the embodiment of the present disclosure are as follows:

[0040] Step 1: During testing, rotate the lower clamp 503, put the device on the intake pipe 12 that needs to be tested, rotate the screw 4 and the bolt 504, so that the upper baffle 1 and the lower baffle 11 fit tightly with the intake pipe 12. When the pressure is too high, the intake pipe 12 will be deformed, and then pressure will be applied to the first pressure sensor 2 and the second pressure sensor 10. The first pressure sensor 2 and the second pressure sensor 10 transmit electrical signals to the pressure controller 301, and the excessive pressure alarm light 302 will sound.

[0041] Step 2: When in use, press the connecting plate 701 , the telescopic column 702 slides in the telescopic tube 703 , and the connecting plate 701 drives the limiting column 6 , and inserts the limiting column 6 into the limiting hole opened at one end of the lower clamping block 503 .

[0042] In summary, through the arrangement of the first pressure sensor 2, the alarm mechanism 3, the screw 4 and the clamping assembly 5, during detection, the lower clamp block 503 is rotated to put the device on the intake pipe 12 to be detected, and the screw 4 and the bolt 504 are rotated to make the upper baffle 1 and the lower baffle 11 fit tightly with the intake pipe 12. When the pressure is too high, the intake pipe 12 is deformed, and at this time, pressure is applied to the first pressure sensor 2 and the second pressure sensor 10. The first pressure sensor 2 and the second pressure sensor 10 transmit electrical signals to the pressure controller 301, and the alarm light 302 sounds when the pressure is too high, which is conducive to close contact with the surface of the intake pipe 12 to make the detection result more accurate. At the same time, when the pressure is too high, the alarm light 302 will sound an alarm to remind the detection personnel. Through the arrangement of the limit column 6 and the telescopic assembly 7, when in use, the connecting plate 701 is pressed, the telescopic column 702 slides in the telescopic tube 703, the connecting plate 701 drives the limit column 6, and the limit column 6 is inserted into the limit hole opened at one end of the lower clamping block 503, which is conducive to the rapid installation and disassembly of the device, provides convenience for the inspection personnel during inspection, and saves inspection time.
