[0002] Oil fume monitoring is the basis for scientific management of oil fume and law enforcement supervision in the catering industry, and is also an important basic work for environmental protection. Its core goal is to provide data on the current status and changing trends of oil fume quality in the catering industry, so as to judge the quality of oil fume, evaluate the current major environmental problems, and provide services for environmental management.

[0003] The process of oil fume monitoring usually includes accepting the task, conducting on-site investigations and collecting data, designing monitoring plans, optimizing monitoring points, collecting samples, transporting and storing samples, pre-processing samples, conducting analytical tests, processing data, and conducting comprehensive evaluations.

[0004] In the existing online monitoring calibration test system, the ventilation duct is composed of multiple sections of pipes, and each section of the pipe is connected to a detection device on the outside, which makes assembly troublesome. Since the connection of multiple sections of pipes needs to ensure the sealing and stability of the connection, this may require more complicated connection processes and tools, increasing the difficulty and time of assembly; each section of the pipe is connected to a detection device on the outside, and each detection device needs to be installed and connected separately, which increases the complexity and workload of installation; and in actual use, the ventilation duct or detection device needs to be maintained or replaced. The existing design of multiple sections of pipes and multiple detection devices makes operation more difficult; at the same time, this design is not convenient for cleaning the inside of the pipe, affecting the accuracy of experimental detection.

[0005] Combining the above problems, we will find that it is difficult to avoid the above problems at the same time when using the existing ones on the market, and even if they can be solved, they need to be solved through external tools, which makes it impossible to achieve the desired effect. Therefore, we propose an online monitoring and calibration test system. Utility Model Content

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Example 1

[0035] The testing mechanism 1 includes a straight pipe 11, a curved pipe 12 and a smoke hood 13. The two ends of the curved pipe 12 are respectively connected to the straight pipe 11 and the smoke hood 13. The bottom of the straight pipe 11 is fixedly connected to a stable seat 14. The bottom of the stable seat 14 is equipped with a universal wheel 15. A push handle 16 is fixedly connected to one side of the stable seat 14. A device box 17 is installed inside the upper end of the stable seat 14. A testing device 18 is installed inside the device box 17. A detection interface is fixedly connected to the straight pipe 11. A plurality of the testing devices 18 are electrically connected to the corresponding detection interfaces.

[0036] A connecting groove 19 is provided on one side of the stabilizing seat 14, and a locking assembly 10 is provided on the other side of the stabilizing seat 14. The locking assembly 10 includes an electric telescopic rod 1001, and one outer end of the electric telescopic rod 1001 is fixedly connected to a servo motor 1002. The outer end of the driving shaft of the servo motor 1002 is fixedly connected to a threaded column 1003.

The two adjacent straight-through tubes 11 are snap-fitted together, and a sealing ring 1005 is provided at the snap-fitting position of the two straight-through tubes 11.

[0037] As a further limitation of the present invention, the curved tube 12 is divided into two sections, the two sections of the curved tube 12 being sealed together, and a stabilizing seat 14 is provided at the bottom of each section of the curved tube 12.

The other end of the straight tube 11 is provided with a locating hole, and the locating pin 1006 cooperates with the locating hole.

[0047] Embodiment three

[0048] Referring to Figure 1-8 The utility model provides a technical scheme: an online monitoring calibration test system, and the utility model makes corresponding improvement to the technical problem mentioned in the background art.

[0049] As a further limitation of the utility model, the smoke generating mechanism 2 includes a generating bin 21, and a gas passage 22 is arranged in the generating bin 21; two independent constant-temperature heating areas 23 are arranged on the inner bottom of the generating bin 21, and a vaporization generating chamber 24 is arranged on the top of each constant-temperature heating area 23. Temperature sensors 25 are arranged in each constant-temperature heating area 23 and vaporization generating chamber 24, which are used for monitoring temperature changes in real time; further including a temperature overrun alarm device, when the heating temperature exceeds the set safety threshold, an audible and visual alarm signal can be sent in time, and the heating power supply is automatically cut off. Two liquid storage tanks 26 are arranged at positions close to the two sides in the generating bin 21 respectively, which are used for storing emulsion one required for generating oil smoke particulate matters and emulsion two required for generating non-methane total hydrocarbon, and high-precision peristaltic pumps are arranged on the inner bottoms of the liquid storage tanks 26, which are used for conveying the emulsion to the corresponding vaporization generating chambers 24 at an accurate rate.

[0050] The vaporization chamber 24 is connected to the liquid storage tank 26 via a high-temperature resistant silicone tube 27 , and an operating door 28 is provided on the outer wall of the generating chamber 21 .

[0051] The specific implementation of this embodiment is as follows: A gas passage 22, a constant temperature heating zone 23, and a vaporization chamber 24 are provided within a generator chamber 21. The emulsion in a liquid storage tank 26 is transported to the vaporization chamber 24 via a high-precision peristaltic pump, where it is heated and vaporized by the constant temperature heating zone 23. Temperature sensors 25 within the constant temperature heating zone 23 and the vaporization chamber 24 monitor the temperature in real time. A temperature over-limit alarm device promptly issues an alarm and cuts off the power supply if the temperature exceeds a safety threshold.

[0052] During operation, the emulsion in the liquid storage tank 26 within the generating chamber 21 of the system's smoke generating mechanism 2 is precisely pumped to the vaporization chamber 24 via a high-precision peristaltic pump. The constant-temperature heating zone 23 heats and vaporizes the emulsion, producing smoke. The smoke then enters the testing mechanism 1, where the straight pipe 11 and curved pipe 12 form a ventilation duct. The detection interface within the straight pipe 11 is electrically connected to various testing devices 18, including a data reference unit, a high-precision flow and pressure measuring instrument, a temperature and humidity measuring instrument, and a sampling port for the device under test, enabling comprehensive smoke testing. The electric telescopic rod 1001 on one side of the stabilizing seat 14 pushes the threaded stud 1003 on the outside of the servo motor 1002 into the connecting groove 19 of the adjacent stabilizing seat 14. The servo motor 1002 drives the threaded stud 1003 to rotate, locking it with the connecting groove 19. The electric telescopic rod 1001 contracts, locking the adjacent straight tubes 11 in place. The sealing ring 1005 at the locking joint ensures a tight seal. The connection between the curved tubes 12, as well as between the curved tubes 12 and the straight tube 11, and between the straight tube 11 and the chassis 32 are similar. After testing, the smoke enters the exhaust mechanism 3, where the exhaust fan 31 in the chassis 32 draws it in. The purifier 33 at the air inlet purifies the smoke, and the purified gas is discharged through the exhaust pipe 34. Through the above process, the system achieves smoke generation, detection, and exhaust purification, solving the problems of cumbersome ventilation duct assembly, difficult maintenance, and poor detection accuracy, thereby improving work efficiency.
