Description

Technical Field

[0001] The present invention relates to the technical field of oil fume monitoring, in particular to a real-time monitoring and early warning system for restaurant oil fume. Background Art

[0002] With the rapid development of the catering industry, the problem of cooking fume emissions has become increasingly prominent, causing serious impacts on the environment and residents' health. To regulate the emission of cooking fume, relevant departments have strengthened the supervision of cooking fume purification, requiring catering companies to install cooking fume purification equipment and ensure its normal operation. However, traditional cooking fume monitoring methods mainly rely on manual inspections or regular testing, which makes it difficult to achieve real-time and continuous monitoring, resulting in low supervision efficiency and the inability to promptly detect cooking fume purification equipment failures or excessive emissions.

[0003] In existing technologies, some oil fume monitoring systems use fixed oil fume sensors to detect exhaust outlets and transmit the data to a backend server for analysis. However, these systems have the following drawbacks in practical applications:

[0004] 1. Existing systems typically only have data collection functions and lack real-time early warning mechanisms. This makes it difficult for catering companies to timely understand emission status and proactively take purification measures, making them vulnerable to penalties for exceeding emission standards.

[0005] 2. Oil smoke can easily enter the device through the gaps in the sensor installation, contaminating the circuit module (such as the main control unit), causing signal transmission abnormalities or equipment damage, affecting system stability;

[0006] 3. Fume sensors are exposed to high-concentration fume environments for a long time and are prone to oil accumulation or damage, requiring frequent cleaning or replacement. However, existing sensors are mostly fixed installation methods, and the disassembly and maintenance process is complicated, often requiring professional tools or technicians to operate, which increases maintenance costs and time.

[0060] See also Figure 1-14 A real-time monitoring and warning system for restaurant oil smoke includes an oil smoke detection device 100, a server 200, an alarm device 300, and a monitoring device 400. First, the oil smoke detection device 100 includes a device chassis 101, an oil smoke detection sensor 102, a lifting module 103, a mounting mechanism 104, an opening and closing mechanism 105, and a main control module 106.

That is, the sliding column 1034 is fixedly connected to the inside of the device chassis 101, the lifting platform 1032 is slidably connected to the sliding column 1034, and the first lead screw 1033 is threadedly connected to the lifting platform 1032. The motor 1031 is fixedly connected to the inside of the device chassis 101, and the motor 1031 is power-connected to the first lead screw 1033. The motor 1031 can drive the first lead screw 1033 to rotate, so that the lifting platform 1032 performs a lifting linear motion;

[0061] Furthermore, the lifting platform 1032 is fixedly connected with a mounting mechanism 104, which is used to fixedly connect the oil smoke detection sensor 102. In this embodiment, please refer to Figure 9 、 Figure 10 , the mounting mechanism 104 includes a mounting platform 1041, a limiting column 1042, a guide column 1043, and a spring 1044, that is, the mounting platform 1041 is fixedly connected to the lifting platform 1032, and the mounting platform 1041 is provided with a mounting slot 1045, and two groups of side frames 1046 are symmetrically fixedly connected to the mounting slot 1045 on the mounting platform 1041, each group of side frames 1046 is fixedly connected to a guide column 1043, and each group of guide columns 1043 is slidably connected to a moving plate 1047, and a spring 1044 is sleeved on the guide column 1043, one end of the spring 1044 is fixedly connected to the side frame 1046, and the other end is fixedly connected to the moving plate 1047, each group of moving plates 1047 is fixedly connected to the limiting column 1042, and a sliding opening is provided on the mounting platform 1041 to match each group of limiting columns 1042, and the limiting column 1042 passes through the sliding opening;

[0062] The top of the above-mentioned oil smoke detection sensor 102 is fixedly connected to the mounting portion 1021, and the mounting portion 1021 is provided with a limiting hole 1022. The mounting portion 1021 is embedded in the mounting groove 1045, and the limiting column 1042 penetrates the limiting hole 1022. In this way, the oil smoke sensor can be installed. When the oil smoke sensor needs to be disassembled, the moving plate 1047 can be moved so that the moving plate 1047 drives the limiting column 1042 to disengage from the limiting hole 1022. For further optimization, please refer to Figure 11 、 Figure 12, a push frame 1048 is fixedly connected to the top surface of the device chassis 101, and a guide platform 1049 is fixedly connected to the push frame 1048 corresponding to each group of moving plates 1047. The guide platform 1049 is provided with a guide slope 10491. When the lifting platform 1032 drives the installation mechanism 104 to rise, the moving plate 1047 can move along the guide slope 10491, and the guide slope 10491 can push the moving plate 1047 to move away from the installation groove 1045, so that the limit column 1042 can be automatically moved from the limit position. The interior of the hole 1022 is detached, which reduces operations and facilitates maintenance. Further optimization is that a positioning strip 1023 is provided on the mounting portion 1021, and a positioning groove 10492 is provided on the mounting platform 1041 to match the positioning strip 1023. When the positioning strip 1023 is embedded in the positioning groove 10492, the limiting column 1042 corresponds to the limiting hole 1022. This makes it easy to accurately install the oil smoke detection sensor 102 on the mounting platform 1041, avoiding the misalignment of the limiting column 1042 and the limiting hole 1022, which leads to the inability to fix;

[0063] Secondly, an inspection port 1011 is provided on the device chassis 101 corresponding to the oil smoke detection sensor 102, and an opening and closing mechanism 105 is provided at the inspection port 1011.

The above-mentioned lifting platform 1032 is fixedly connected to a rack 1056, and the gear 1055 is meshed with the rack 1056. In this way, when the lifting platform 1032 rises, the rack 1056 can drive the gear 1055 to move, and then the worm 1059 can be rotated. 59 drives the worm gear 1058 to rotate, so that the second lead screw 1053 rotates, and the traction platform 1054 can pull the closing plate 1051 to move linearly, so that the closing plate 1051 opens the inspection port 1011. At this time, the rising oil smoke detection sensor 102 is close to the inspection port 1011, so that the oil smoke detection sensor 102 can be removed for cleaning and replacement, without the need to disassemble the entire oil smoke detection device 100, and no additional tools are needed, which improves the convenience of maintenance. In addition, the above-mentioned pushing frame 1048 is close to the inspection port The repair opening 1011 allows the installation mechanism 104 to release the oil smoke detection sensor 102 when the oil smoke detection sensor 102 rises and approaches the inspection opening 1011. Of course, a movement opening is also provided on the device chassis 101 corresponding to the rack 1056, so that when the lifting platform 1032 rises, the rack 1056 has space to rise.

At this time, the sealing ring 1024 seals the insertion port 1014, which can prevent oil smoke from entering the interior of the device chassis 101 and damaging the internal components, especially the main control module 106, affecting the system stability and reducing the failure rate of the device;

[0066] Furthermore, a main control module 106 is provided inside the chassis.
