[0025] In order to make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0026] Refer to Figures 1-4, the present utility model provides a technical solution: an acid and alkali resistant in-pipe monitoring device, including an installation rod 23, a monitoring mechanism 1 and a data collector 17. The monitoring mechanism 1 can comprehensively detect the oil pipe body 19 and understand the internal corrosion condition of the oil pipe body 19. The monitoring mechanism 1 includes a monitoring box 11. The monitoring box 11 is arranged on one side of the installation rod 23. Monitoring rods 15 are inserted through all four sides of the monitoring box 11. An installation ring 13 is fixed on the surface of the monitoring rod 15. A spring 14 is arranged at the bottom of the installation ring 13. A pressure sensor 25 is arranged inside the monitoring box 11. Through the mutual cooperation of the oil pipe body 19, the monitoring box 11, the installation rod 23, the monitoring rods 15 and the pressure sensor 25, when an operator needs to detect the inside of the oil pipe body 19, the operator can first put the monitoring box 11 into the oil pipe body 19 through the installation rod 23. When it is inserted to a proper position, the operator can stop the movement of the monitoring box 11. At this time, the four groups of monitoring rods 15 can be clamped into the oil pipe body 19. After the clamping is completed, then the installation rod 23 is taken out. At this time, the spring 14 drives the monitoring rods 15 to always fit with the inner cavity of the oil pipe body 19. When any one of the springs 14 is subjected to pressure, the pressure will be transmitted to the pressure sensor 25, enabling the pressure sensor 25 to sense the change in pressure and convert the pressure change into a signal, and transmit the information to the monitoring terminal, so as to comprehensively detect the oil pipe body 19 and understand the internal corrosion condition of the oil pipe body 19.

[0027] Refer to Figures 1-4, in a preferred embodiment, the data collector 17 is disposed on one side of the monitoring box 11. The surface of the mounting rod 23 is provided with an oil pipe body 19. The inner cavity of the oil pipe body 19 is provided with an acid and alkali resistant layer 18. The acid and alkali resistant layer 18 is made of acid and alkali resistant materials such as stainless steel, special alloy or coating to resist the corrosive medium that may exist inside the oil pipe body 19. Installation holes 12 are formed on all four sides of the monitoring box 11. The monitoring rod 15 is disposed inside the installation holes 12. The other end of the spring 14 is disposed inside the installation holes 12. A fixing ring 2 is provided on the other side of the monitoring box 11. A groove is formed inside the mounting ring 13, and a sealing ring 16 is disposed inside the groove. By providing the sealing ring 16, the sealing performance of the monitoring rod 15 can be improved. Through the mutual cooperation of the monitoring box 11, the oil pipe body 19, the mounting rod 23, the electric telescopic rod 21, the jack 22 and the data collector 17, when the operator needs to place the monitoring box 11 inside the oil pipe body 19, the operator can first place one end of the mounting rod 23 inside the fixed pipe, and then control the electric telescopic rod 21 to extend so that it is inserted into the jack 22. After completion, the monitoring box 11 is placed inside the oil pipe body 19. When placing, the data collector 17 can also be synchronously placed inside the oil pipe body 19, so that various parameters inside the oil pipe body 19 can be monitored and measured, improving the monitoring effect of the oil pipe body 19.

[0028] Referring to Figures 1-4 , in a preferred embodiment, jacks 22 are formed on both sides of the inner cavity of the fixing ring 2. By forming the jacks 22, it is convenient for the operator to limit the position of the mounting rod 23. A handle 24 is provided at one end of the mounting rod 23. Two groups of symmetrically arranged electric telescopic rods 21 are disposed inside the mounting rod 23. The electric telescopic rods 21 are disposed inside the jacks 22. The monitoring rods 15 are respectively disposed on all four sides of the pressure sensor 25. The size of the sealing ring 16 is adapted to the size of the installation hole 12. A limiting groove is formed inside the monitoring box 11. By providing the limiting groove, the pressure sensor 25 can be placed. The pressure sensor 25 is disposed inside the limiting groove. Both the data collector 17 and the pressure sensor 25 can transmit signals to the monitoring terminal, facilitating the operator to detect the oil pipe body 19.

[0029] Specifically, the working process or working principle of the acid-resistant and alkali-resistant oil pipe monitoring equipment is as follows: in the specific monitoring of the acid-resistant and alkali-resistant oil pipe, it is necessary to measure all aspects of the inside of the oil pipe, but the existing oil pipe inspection device can only measure the position of the oil pipe mouth, and cannot accurately measure the middle part of the oil pipe. The inspection is not comprehensive, which affects the monitoring effect and is inconvenient for the operator to use. Therefore, the technical solution can solve the above problems. When the operator needs to inspect the inside of the oil pipe body 19, the operator can first put the monitoring box 11 into the inside of the oil pipe body 19 through the installation rod 23. When it is inserted to the appropriate position, the operator can stop the movement of the monitoring box 11. At this time, the four groups of monitoring rods 15 can be inserted into the inside of the oil pipe body 19. When the insertion is completed, the operator can control the electric telescopic rod 21 to be retracted, release the limit on the installation rod 23 from the socket 22, and then take out the installation rod 23. At this time, the spring 14 drives The monitoring rod 15 is always in contact with the inner cavity of the oil pipe body 19. When any group of springs 14 is subjected to pressure, the pressure will be transmitted to the pressure sensor 25, so that the pressure sensor 25 can sense the change in pressure, convert the pressure change into a signal, and transmit the information to the monitoring terminal, so that the oil pipe body 19 can be fully inspected and the internal corrosion of the oil pipe body 19 can be understood. When the operator needs to put the monitoring box 11 into the interior of the oil pipe body 19, the operator can first put one end of the mounting rod 23 into the interior of the fixed pipe, and then control the electric telescopic rod 21 to extend so that it is inserted into the interior of the jack 22. When completed, the monitoring box 11 is put into the interior of the oil pipe body 19. When it is put in, the data collector 17 can also be put into the interior of the oil pipe body 19 simultaneously, so that various parameters inside the oil pipe body 19 can be monitored and measured, thereby improving the monitoring effect of the oil pipe body 19. At this point, all processes are completed.

[0030] It should be noted that the electric telescopic rod 21, the data collector 17 and the pressure sensor 25 are all electrically connected to the external power supply and are devices or equipment existing in the prior art, or are devices or equipment that can be realized in the prior art. Their power supply, specific composition and principles are clear to those skilled in the art, so they will not be described in detail.
