[0031] In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features known in the art are not described to avoid confusion with the present invention.

[0032] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside shown in the figures of the present invention, and are explained here together.

[0033] This embodiment provides Figures 1 to 4 The monitoring device for safety inspection of petrochemical equipment shown includes: a petroleum and petrochemical storage tank 1, an inspection liquid discharge pipe 8, a monitoring assembly 9, a liquid delivery guide pipe 15, and an inspection bearing assembly 10.

[0034] In this embodiment, the petroleum and petrochemical storage tank 1 is used to contain petroleum liquid and has a stirring motor 3 on the top. The output shaft of the stirring motor 3 is connected to an agitator (not shown in the figure) in the inner cavity of the petroleum and petrochemical storage tank 1. The agitator includes a stirring shaft and stirring blades welded to the outer wall of the stirring shaft; the stirring motor 3 drives the agitator inside the storage tank to rotate to keep the petroleum liquid evenly mixed, which helps to obtain more accurate samples and promotes consistency in temperature distribution.

[0035] In this embodiment, the inspection drain pipe 8 is connected to the upper part of the peripheral outer wall of the petroleum and petrochemical storage tank 1 and is connected to the inner cavity of the petroleum and petrochemical storage tank 1 through the end through a pipeline; the inspection drain pipe 8 extracts petroleum liquid samples from the petroleum and petrochemical storage tank 1 to the outside for further quality inspection.

[0036] In this embodiment, monitoring assembly 9 is positioned around test drain pipe 8 and monitors the quality of the petroleum liquid discharged from test drain pipe 8. Monitoring assembly 9 includes a liquid pump 13 and a thermometer 14 connected to the test drain pipe 8. Thermometer 14 measures the temperature of the petroleum liquid in test drain pipe 8, helping to assess whether the liquid is in suitable operating conditions. Liquid pump 13 is responsible for pumping liquid from petroleum and petrochemical storage tank 1 to test drain pipe 8 and is a key component in achieving automatic sampling.

[0037] In this embodiment, the infusion guide tube 15 vertically passes through the bottom of the free end of the inspection and drainage tube 8;

[0038] In this embodiment, the inspection carrying assembly 10 is arranged on one side of the petroleum and petrochemical storage tank 1 and is located directly below the infusion guide tube 15. The inspection carrying assembly 10 includes two inspection cups 20 that slide alternately in a linear manner. The petroleum liquid output from the infusion guide tube 15 falls into the required inspection cup 20.

[0039] In this embodiment, a visual recognition CCD camera 17 is further provided on the outer wall of the free end of the inspection discharge tube 8. The visual recognition CCD camera 17 detects and identifies the required inspection cup 20 which slides vertically directly below the infusion guide tube 15 to carry and output the falling petroleum liquid.

[0040] In this embodiment, the liquid pump 13 is used to pump the petroleum liquid in the petroleum and petrochemical storage tank 1 into the inspection drainage pipe 8. The detection head of the thermometer 14 monitors the temperature in the inspection drainage pipe 8, opens the solenoid valve in the infusion guide pipe 15, and the petroleum liquid is output from the infusion guide pipe 15 and falls into the required inspection cup 20. The two inspection cups 20 slide alternately under the infusion guide pipe 15 to hold petroleum liquid in different states or temperatures and whether or not it is stirred, thereby completing the inspection and monitoring of petrochemical products, replacing the operation of manually climbing and sampling the petroleum in different states. This not only enables real-time monitoring, but also helps to improve inspection efficiency.

[0041] In this embodiment, an L-mounting plate 16 is installed on the outer wall of the inspection drain pipe 8 away from the petroleum and petrochemical storage tank 1 by screws, and a visual recognition CCD camera 17 is longitudinally embedded in the end of the L-mounting plate 16 away from the inspection drain pipe 8, so that the lens end of the visual recognition CCD camera 17 faces downward.

[0042] In this embodiment, the inspection bearing assembly 10 further includes two symmetrically arranged supporting columns 11 and a linear guide member 12 fixedly installed between the top ends of the two supporting columns 11 .

[0043] In this embodiment, two slider supports 19 are symmetrically slidably connected to the top surface of the linear guide member 12 , and a guide motor 18 is installed at one end of the housing of the linear guide member 12 .

[0044] In this embodiment, each slider support 19 has clamping assemblies on both sides, which centripetally clamp the test cup 20. The support column 11 and linear guide 12 form a stable platform on which the slider support 19 can move, ensuring that the test cup 20 is accurately positioned below the infusion guide tube 15.

[0045] In this embodiment, side plates 23 are symmetrically welded on both sides of the top surface of each slider support 19, and the clamping assembly includes a clamping screw 21 centripetally passing through each side plate 23 and a clamping block 22 fixed to the screw end of the clamping screw 21.

[0046] In this embodiment, the two clamping screws 21 are screwed forward, driving the clamping block 22 to clamp against the outer wall of the test cup 20. The clamping screws 21 and the clamping block 22 work together to securely hold the test cup 20 by adjusting the side plates 23, preventing loosening due to mechanical movement.

[0047] In this embodiment, a top cover is installed on the top surface of the petroleum and petrochemical storage tank 1, an inverted U-shaped frame 2 is fixed in the middle of the top cover, a stirring motor 3 is installed on the top surface of the U-shaped frame 2, and auxiliary inlets 5 are provided on both sides of the top cover.

[0048] In this embodiment, a liquid inlet pipe 4 is connected to one side of the U-shaped frame 2 and extends through the top surface of the top cover. Multiple support legs 6 are symmetrically welded to the outer wall of the petroleum and petrochemical storage tank 1. A power distribution control box 7 is mounted on the outer wall of one of the support legs 6. The power distribution control box 7 contains a PLC for controlling the power on and off of various electronic components.

[0049] Working principle:

[0050] The monitoring device for safety inspection of petrochemical equipment first adds the petroleum liquid to be inspected into the petroleum and petrochemical storage tank 1 through the liquid inlet pipe 4. This process can be completed by a manual or automatic control system. Once the petroleum liquid in the tank reaches a predetermined amount, the stirring motor 3 starts and drives the stirrer (not shown in the figure) inside the tank to rotate to ensure that the petroleum liquid is evenly mixed. This step is very important for ensuring the consistency and representativeness of the sample. During the stirring process, the thermometer 14 continuously monitors the temperature of the petroleum liquid and feeds the data back to the monitoring system via wired or wireless communication, such as the PLC in the distribution control box 7. If a sample at a specific temperature is required, the system will adjust the operating conditions according to the settings.

[0051] When the petroleum liquid reaches the required state, the liquid pump 13 starts working, extracting the petroleum liquid from the petrochemical storage tank 1 and delivering it to the liquid infusion guide pipe 15 through the inspection drain pipe 8. At this time, the thermometer 14 continues to monitor the liquid temperature to ensure that the sample meets the requirements.

[0052] At the same time, the visual recognition CCD camera 17 identifies and confirms which test cup 20 has been moved to the position directly below the infusion guide tube 15. The guide rail motor 18 drives the rotation of the screw in the housing of the linear guide 12, and the screw drives the movement of the sliding block support 19 along the linear guide 12, accurately positioning the empty test cup 20 to the position ready to receive the liquid.

[0053] When the test cup 20 is in place, the clamping block 22 is tightly attached to the outer wall of the test cup 20 by screwing the clamping screw 21, so as to firmly fix the test cup 20 on the sliding block support 19, preventing displacement during sampling.

[0054] Subsequently, the electromagnetic valve in the infusion guide tube 15 is opened, and the petroleum liquid is guided to fall into the test cup 20. The visual recognition CCD camera 17 monitors the entire process to ensure that the liquid flows correctly into the target container. After completing a sampling, the guide rail motor 18 is actuated again to move the next empty test cup 20 below the infusion guide tube 15, and the above process is repeated to achieve continuous and alternating sampling operations. In this way, multiple samples can be collected at different time points, different temperatures or different stirring states.

[0055] The collected samples can be directly used for subsequent quality detection and analysis. Since the entire sampling process is automated, the influence of human factors is reduced, and the reliability and consistency of the detection results are improved.
