[0002] With the acceleration of urbanization and the rapid development of the catering industry, the issue of oil fume emissions has gradually become the focus of environmental governance. Catering oil fume is a complex mixture produced by cooking oil and ingredients during high-temperature cooking. Its main components include volatile organic compounds (VOCs), particulate matter, polycyclic aromatic hydrocarbons (PAHs) and other harmful substances. These pollutants not only have a serious impact on air quality, but may also cause harm to the health of surrounding residents, such as respiratory diseases and allergic reactions. Therefore, strict emission standards have been formulated, requiring restaurant owners to install purification equipment and monitoring systems to monitor and manage oil fume emissions in real time;

[0003] Most of the existing restaurant smoke exhaust monitoring systems adopt a fixed installation structure. The oil smoke sensor is directly exposed to the flue. After a long period of operation, a large amount of grease and impurities will adhere to the sensor surface, resulting in a decrease in the sensor's detection accuracy and inaccurate monitoring data. Therefore, it needs to be cleaned regularly. Conventional cleaning methods mostly rely on manual operation, which is labor-intensive. In addition, the oil smoke sensor is generally installed at a high height, making it difficult to maintain.

[0004] In addition, in terms of energy utilization, traditional smoke exhaust monitoring systems mostly rely on external power supply. Since the catering smoke exhaust system needs to operate around the clock, this external power supply method invisibly increases the energy consumption and electricity bill expenditure of the catering company.

[0036] Beneficial effects of the present invention:

[0037] 1. The monitoring box can be installed on the restaurant exhaust pipe. The purified oil smoke discharged from the restaurant exhaust pipe can enter the smoke guide tube. When the oil smoke is discharged, it can drive the wind power impeller to rotate, thereby realizing wind power generation. The generated electricity is stored in the battery, and the battery is used to power the oil smoke sensor.

The bottom end of the oil fume sensor is fixedly connected with a sealing bottom platform, and the top end is fixedly connected with a sealing top platform, and a sealing matching platform is provided in the monitoring hole to match the sealing top platform. When the lifting component drives the oil fume sensor to be located in the smoke guide tube, a seal is formed between the sealing top platform and the sealing matching platform. When the lifting component drives the oil fume sensor to be located in the monitoring hole, the sealing bottom platform can seal the monitoring hole, thereby preventing oil fume from entering the monitoring box, thereby protecting the battery and other components inside the monitoring box, and enhancing the service life of the device. When monitoring is not needed, the oil fume sensor can be stored to avoid long-term exposure to the outside world, which affects the service life;

[0040] 4. The lifting components and the high-pressure air pump are powered by a set of drive motors. That is, when the drive motor rotates forward, it drives the lead screw to rotate, thereby realizing the lifting and lowering movement of the lifting platform and the oil fume sensor thereon. When the drive motor rotates reversely, it drives the air pump body to work, thereby realizing the work of the cleaning components. This can reduce the number of motors, thereby reducing the failure rate of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0061] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0062] Example 1

[0063] A restaurant smoke exhaust monitoring system includes a monitoring box 100, a smoke exhaust monitoring mechanism, and a monitoring system. First, please refer to Figure 1-4 The monitoring box 100 is provided with a smoke inlet 101 and a smoke exhaust port 102, the smoke inlet 101 is fixedly connected to the restaurant smoke exhaust pipe, and a smoke exhaust monitoring mechanism is provided in the monitoring box 100, and the smoke exhaust monitoring mechanism is used to monitor the oil smoke exhausted from the restaurant smoke exhaust pipe;

[0064] The above-mentioned smoke exhaust monitoring mechanism includes a smoke guide tube 200, a wind power generation component 300, a lifting component 400, an oil smoke sensor 500 and a cleaning component 600, that is, a smoke guide tube 200 is fixedly connected in the monitoring box 100, and the smoke guide tube 200 is connected to the smoke inlet 101 and the smoke outlet. The monitoring box 100 is also provided with a wind power generation component 300, and a wind power generation impeller 301 in the wind power generation component 300 is located in the smoke guide tube 200. When the oil smoke is extracted by the fan and discharged outward, the oil smoke can drive the wind power generation impeller 301 to rotate, so that the wind power generation component 300 generates electricity;

[0065] Specifically, see Figure 1 , Figure 5 , Figure 6The monitoring box 100 is provided with a storage battery 302, and the wind power generation component 300 also includes a generator 303, a wind power generation controller 304, and a mounting frame 305, that is, the mounting frame 305 is fixedly connected to the inner wall of the smoke guide tube 200, and the mounting frame 305 is rotatably connected to the wind power generation impeller 301, and the first bevel gear 306 is fixedly connected to the axle of the wind power generation impeller 301, and the middle tube 201 is rotatably connected to the power input shaft 307, the bottom end of the power input shaft 307 is located in the middle tube 201, and the top end is located in the monitoring box 100, and the power input shaft 307 is rotatably connected to the middle tube 201. The bottom end of the wind turbine 107 is fixedly connected with a second bevel gear 308, and the second bevel gear 308 is meshed with the first bevel gear 306. A generator 303 is fixedly connected in the monitoring box 100, and the top end of the power input shaft 307 is connected to the generator 303. The generator 303 is electrically connected to the wind power generation controller 304, and the wind power generation controller 304 is electrically connected to the battery 302. In this way, when the wind power generation impeller 301 rotates, the generator 303 can be driven to work, and the electric energy generated by the generator 303 can be stored in the battery 302 through the wind power generation controller 304;

[0066] Further optimization, in order to improve the effect of wind power generation, the above-mentioned smoke guide tube 200 includes a middle tube 201 and end tubes 202 fixedly connected to both ends of the middle tube 201, and the two groups of end tubes 202 are fixedly connected to the smoke inlet 101 and the smoke exhaust port 102 respectively. The diameter of the middle tube 201 is smaller than the diameter of the end tube 202, and the diameter of the end tube 202 is greater than or equal to the diameter of the smoke inlet 101 and the smoke exhaust port 102. The mounting frame 305 is fixedly connected to the inner wall of the middle tube 201, so that the wind power impeller 301 is located in the middle tube 201. In this way, when the oil smoke passes through the end tube 202 and enters the interior of the middle tube 201, because the diameter becomes smaller, the wind speed when the oil smoke is discharged can be strengthened, thereby driving the wind power impeller 301 to rotate faster and increase the power generation;

[0067] Furthermore, a lifting component 400 is also provided inside the monitoring box 100, and the lifting component 400 includes a lifting platform 401, a driving motor 402, a lead screw 403 and a sliding column 404, that is, a sliding column 404 is fixedly connected inside the monitoring box 100, a lifting platform 401 is slidably connected to the sliding column 404, a lead screw 403 is threadedly connected to the lifting platform 401, a driving motor 402 is fixedly connected inside the monitoring box 100, the driving motor 402 is dynamically connected to the lead screw 403, a mounting frame 405 is fixedly connected to the lifting platform 401, and the oil smoke sensor 500 is fixedly connected to the mounting frame 405, so that the lead screw 403 can be driven to rotate by the driving motor 402, so that the lifting platform 401 is lifted and lowered, and the oil smoke sensor 500 is lifted and lowered;

[0068] Also, see Figure 5-8The smoke guide tube 200 is also fixedly connected with a smoke monitoring platform 203, and a monitoring hole 204 is provided on the smoke monitoring platform 203. The smoke sensor 500 corresponds to the monitoring hole 204. When the lifting platform 401 descends, the smoke sensor 500 can be driven to pass through the monitoring hole 204 and be located in the smoke guide tube 200. In this way, when the smoke is discharged through the smoke guide tube 200, the smoke sensor 500 can detect the smoke.

[0069] Furthermore, the oil fume sensor 500 is matched with the monitoring box 100 and is also provided with a cleaning component 600. After the lifting component 400 drives the oil fume sensor 500 to move into the monitoring hole 204, the cleaning component 600 can clean the oil fume sensor 500. Specifically, the cleaning component 600 includes a high-pressure air pump 601, a cleaning nozzle 602, and an air filter 603. That is, a plurality of cleaning nozzles 602 are fixedly connected in the monitoring hole 204, and a high-pressure air pump 601 is fixedly connected in the monitoring box 100. The compressed air pump 601, the air outlet of the high-pressure air pump 601 is connected to the plurality of cleaning nozzles 602 through an air pipeline 604, the air inlet of the high-pressure air pump 601 is fixedly connected to an air inlet pipeline 605, and the air inlet pipeline 605 is also fixedly connected to an air filter 603, so that the outside air can be drawn into the air filter 603 through the high-pressure air pump 601, and the filtered high-pressure air can be sprayed out through the cleaning nozzle 602, and the sprayed high-pressure air can wash the oil smoke sensor 500;

[0070] Optimizing, see Figure 7-9 The cleaning nozzle component 602 includes an annular tube 606 and a nozzle body 607 fixedly connected to the annular tube 606. The nozzle body 607 is tilted downward. The lifting component 400 can drive the oil smoke sensor 500 to be located inside the annular tube 606. Each group of annular tubes 606 is fixedly connected with a bronchial pipe 608. Multiple groups of bronchial pipes 608 are fixedly connected to a gas distributor 609. The gas pipeline 604 is fixedly connected to the gas distributor 609. In this way, the air generated by the high-pressure air pump 601 can be evenly distributed to each group of annular tubes 606 through the gas distributor 609. Then the air is ejected through multiple groups of nozzle bodies 607 to clean the oil smoke sensor 500. The nozzle is facing downward, so that the impurities cleaned can be washed to the bottom.

When the oil fume sensor 500 is located inside the monitoring hole 204, the sealing bottom platform 501 and the bottom of the oil fume monitoring platform 203 collide with each other to achieve the sealing of the monitoring hole 204. In this way, oil fume can be prevented from entering the monitoring box 100, so that the battery 302 and other components inside the monitoring box 100 are protected to enhance the service life of the device. When monitoring is not needed, the oil fume sensor 500 can be stored to avoid long-term exposure to the outside world and affect the service life.

[0072] Finally, see Fig.10 , the oil fume sensor 500 is matched with the monitoring system to realize the real-time monitoring of the exhaust oil fume, wherein the monitoring system includes a microcontroller 700, a motor controller 701, a communication module 702, a cloud server 703 and a monitoring PC terminal 704;

After the communication module 702 transmits the signal to the microcontroller 700, the microcontroller 700 can transmit the signal to the motor controller 701, so that the motor controller 701 controls the drive motor 402 to work, so as to realize the cleaning or storage of the oil smoke sensor 500, and the battery 302 provides power for all the above-mentioned components that need power.

[0075] Example 2

[0076] See also Fig.11 , a restaurant smoke exhaust monitoring system, based on Example 1, this embodiment further states that in order to reduce the number of driving sources and reduce device failures, a set of driving motors 402 are used to provide power for the high-pressure air pump 601 and the lifting component 400, namely:

[0077] The lead screw 403 in Example 1 adopts a reciprocating lead screw 403, while the high-pressure air pump 601 adopts an unpowered air pump body. The drive motor 402 and the lead screw 403 are dynamically connected through a first transmission member. The first transmission member includes a first ratchet member 801, a worm 802, a worm wheel 803, a gear A804, and a gear B805. That is, a worm wheel 803 is fixedly connected to the lead screw 403, a worm 802 is rotatably connected in the monitoring box 100, the worm 802 is meshingly connected with the worm wheel 803, the worm 802 is fixedly connected with the gear A804, an output main shaft 806 is fixedly connected to the drive motor 402, a gear B805 is fixedly connected to the output main shaft 806, the gear B805 is meshingly connected with the gear A804, the first ratchet member 801 Located on the worm 802, and the first ratchet wheel 801 is located on the power output side of the gear A804. When the driving motor 402 rotates in the forward direction, the power can be transmitted to the gear B805, and then the gear B805 drives the gear A804, and finally the worm 802 rotates to drive the worm wheel 803 to rotate, and finally the screw 403 rotates. By utilizing the self-locking effect of the worm wheel 803 and the worm 802, the packaging lifting platform 401 can be in a relatively stable state after the movement. When the screw 403 is a reciprocating screw 403, the screw 403 can make the lifting platform 401 move without changing the rotation direction. However, if the driving motor 402 rotates in the reverse direction, the screw 403 will not rotate under the action of the first ratchet wheel 801.

[0078] Furthermore, the air pump body is powered by a second transmission member, which includes a second ratchet member 901, a driving pulley 902, a driven pulley 903, and a transmission belt 904, that is, the above-mentioned output main shaft 806 is fixedly connected with a driving pulley 902, and a driven pulley 903 is fixedly connected to the pump shaft 905 of the air pump body.

A second ratchet member 901 is provided on the pump shaft 905, and the second ratchet member 901 is located on the power output side of the driven pulley 903. When the drive motor 402 rotates in the reverse direction, the power can be transmitted to the pump shaft 905, so that the air pump body works. However, if the drive motor 402 rotates in the forward direction, the air pump body does not work under the action of the second ratchet member 901.
