[0026] like Figure 1-Figure 11 As shown, a multi-sensor based odor gas monitoring device, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 7 , Figure 8 and Fig. 9 , including a supporting mechanism 1, a blocking mechanism 2 is installed at the top and bottom of the supporting mechanism 1, a lifting mechanism 3 is arranged outside the supporting mechanism 1, a monitoring mechanism 4 is installed at the front end of the lifting mechanism 3, a protective mechanism 5 is installed at the top of the monitoring mechanism 4, the supporting mechanism 1 is used to support the lifting mechanism 3 and the monitoring mechanism 4, the blocking mechanism 2 is used to block the front end of the supporting mechanism 1, the lifting mechanism 3 is used to drive the monitoring mechanism 4 to rise and fall, the monitoring mechanism 4 includes a protective box 401, a mounting plate 408 is fixedly connected to the inside of the protective box 401, and a plurality of gas sensors 410 with different functions are fixedly connected to the front of the mounting plate 408 near the top; The lifting mechanism 3 includes a carrying part 301, the rear end of the carrying part 301 is fixedly connected to a rear sealing part 302 by bolts, a gear 305 is movably installed inside the carrying part 301 and penetrating the rear end of the carrying part 301, a servo motor 303 is fixedly connected to one side of the carrying part 301, and the output shaft of the servo motor 303 is fixedly connected to the rotating shaft of the gear 305, a protective casing 304 is fixedly connected to one side of the carrying part 301 and located outside the servo motor 303 by bolts, and the supporting mechanism 1 includes a vertical pole 101, a plurality of tooth grooves 102 are opened at the front end of the vertical pole 101, and the gear 305 is meshed and connected with the vertical pole 101 through the tooth grooves 102.

[0027] Specifically, the lifting mechanism 3 and the monitoring mechanism 4 are supported by the supporting mechanism 1. When odor monitoring is performed, the servo motor 303 is started to drive the gear 305 to rotate, and the rotation of the gear 305 cooperates with the tooth groove 102 to drive the entire lifting mechanism 3 to rise and fall along the vertical pole 101, and drive the monitoring mechanism 4 to rise and fall during the lifting process. The monitoring mechanism 4 monitors the composition and concentration of odorous gases in the air, which makes it convenient for the monitoring mechanism 4 to monitor the odor of ambient air at different heights, expands the monitoring range, and makes the monitoring data more accurate and representative. In the process of lifting the lifting mechanism 3, the blocking mechanism 2 is driven to block the front end of the vertical pole 101 to prevent dust and moisture from entering between the gear 305 and the tooth groove 102, to prevent dust and moisture from polluting and corroding the gear 305 and the tooth groove 102, and to prevent the operation of the gear 305 from being obstructed.

[0028] Please refer to Fig. 9 and Fig.10 The sealing mechanism 2 includes a winding box 201, which is fixedly connected to the vertical pole 101. A central column 202 is fixedly installed in the center of the winding box 201. A clockwork spring 203 is arranged on the outside of the central column 202. A waterproof cloth 204 is wound around the outer ring of the clockwork spring 203. The middle part of the clockwork spring 203 is fixedly connected to the central column 202, the end of the clockwork spring 203 is fixedly connected to one end of the waterproof cloth 204, and the other end of the waterproof cloth 204 is fixedly connected to the mounting part 301.

[0029] Specifically, during the lifting and lowering process of the lifting mechanism 3, the carrying member 301 is lifted and lowered synchronously, and the waterproof cloth 204 is pulled out from the winding box 201 through the carrying member 301, and the front end of the vertical rod 101 is blocked to prevent dust and moisture from polluting and corroding the gear 305 and the tooth groove 102, which causes the operation of the gear 305 to be blocked. When the waterproof cloth 204 is recovered, the waterproof cloth 204 is rolled up through the spring spring 203, which makes it easy to collect the released waterproof cloth 204 into the winding box 201, so that the waterproof cloth 204 can be reused repeatedly.

[0030] Please refer to Figure 4 , Figure 5 and Fig.10The sealing mechanism 2 also includes a second magnetic strip 205 fixedly connected to both sides of the waterproof cloth 204, and the supporting mechanism 1 also includes a first magnetic strip 103 that passes through the front end of the vertical pole 101 and is located on both sides of a plurality of tooth grooves 102. The second magnetic strip 205 is magnetically connected to the first magnetic strip 103. A base 104 is fixedly installed at the bottom of the vertical pole 101, one of the winding boxes 201 is located at the top of the vertical pole 101, and the other winding box 201 passes through the front and rear ends of the vertical pole 101 and is close to the base 104.

[0031] Specifically, the base 104 is used in conjunction with external bolts to facilitate fixing of the support mechanism 1, thereby completing the installation of the foreign gas monitoring equipment. When the waterproof cloth 204 is released or recovered, the mutual attraction between the magnetic strip 1 103 and the magnetic strip 2 205 allows the waterproof cloth 204 to adhere closely to the vertical pole 101, thereby preventing dust and moisture from penetrating through the gap between the vertical pole 101 and the waterproof cloth 204.

[0032] Please refer to Figure 6 and Figure 7 The monitoring mechanism 4 also includes a heat dissipation window 402 that penetrates through the lower part of the box body on both sides of the protection box 401. The front end of the protection box 401 is hinged with a box door 403 through a hinge, and a control panel 409 is fixedly installed in the center of the front end of the mounting plate 408.

[0033] Specifically, when monitoring odorous gases, the box door 403 is opened, and the corresponding monitoring parameters are set through the control panel 409. When the electrical components inside the protective box 401 generate heat during operation, the heat is dissipated through the heat dissipation window 402 to prevent the operating temperature inside the protective box 401 from being too high, which would affect the service life of the electrical components.

[0034] Please refer to Figure 6 and Figure 7 The monitoring mechanism 4 also includes a wind speed sensor 404 fixedly installed on one side of the protection box 401, a wind direction sensor 405 fixedly installed on the other side of the protection box 401, an alarm 407 fixedly installed on one side of the top of the protection box 401, and a gas collector 406 fixedly installed on the other side through the top of the protection box 401.

[0035] Specifically, ambient air is collected through the gas collector 406, and the gas sensor 410 inside the protective box 401 monitors the composition and concentration of odorous gases in the air. The wind speed sensor 404 measures the wind speed to evaluate the diffusion speed of the odorous gas. The wind direction is measured by the wind direction sensor 405 to determine the source direction of the odorous gas, which helps to track the source of pollution and take corresponding control measures. When the concentration of the monitored odorous gas exceeds the set threshold, an alarm is sounded through the alarm 407 to remind relevant personnel to pay attention and take corresponding countermeasures.

[0036] Please refer to Figure 7The monitoring mechanism 4 includes a circuit board fixedly mounted on the back of the mounting plate 408, a signal processing and analysis module, a data storage module and a communication module.

[0037] Specifically, after the gas collected by the gas collector 406 is converted into an electrical signal through the gas sensor 410, the signal processing and analysis module is responsible for amplifying, filtering and converting the electrical signal output by the gas sensor 410, and then analyzing the signal through an algorithm to obtain the composition and concentration of the odor gas in the gas to be tested. The data storage module then stores and manages the data monitored by the odor gas monitoring equipment for easy viewing and analysis. At the same time, the communication module transmits the data monitored by the odor gas monitoring equipment to a remote server or data center in real time to realize remote monitoring and management.

[0038] Please refer to Figure 2 and Figure 8 The rear sealing member 302 is sleeved with the vertical pole 101, and the mounting member 301 is fixedly connected with the protective box 401 by bolts.

[0039] Please refer to Figure 1 , Figure 6 and Fig.11 The protection mechanism 5 includes a protection mesh cover 501 , and the protection mesh cover 501 is located outside the gas collector 406 .

[0040] Specifically, the protective mesh cover 501 is used to protect the gas collector 406 to prevent foreign objects from flowing with the wind and hitting the gas collector 406. At the same time, larger foreign objects are intercepted to prevent larger foreign objects from entering the gas collector 406 and causing blockage, thereby extending the service life of the gas collector 406.

[0041] Please refer to Figure 1 , Figure 6 and Fig.11 The protection mechanism 5 also includes an impeller 502 movably mounted on the top of the protection mesh cover 501 , and four scraping strips 503 are fixedly mounted on the outer periphery of the impeller 502 , and the inner surface of the scraping strip 503 is in contact with the outer surface of the protection mesh cover 501 .

[0042] Specifically, the impeller 502 is driven by wind to rotate, and the impeller 502 then drives the four scraping strips 503 to move along the surface of the protective mesh cover 501 to scrape off foreign matter attached to the surface of the protective mesh cover 501, thereby preventing the protective mesh cover 501 from being blocked by the presence of foreign matter and affecting the entry of ambient air into the gas collector 406.

[0043] Please refer to Figure 1 , Figure 6 and Fig.11 The protection mesh cover 501 is fixedly connected to the protection box 401 by bolts.

[0044] How it works The lifting mechanism 3 and the monitoring mechanism 4 are supported by the supporting mechanism 1. When odor monitoring is performed, the gas collected by the gas collector 406 is converted into an electrical signal through the gas sensor 410. The signal processing and analysis module is responsible for amplifying, filtering and converting the electrical signal output by the gas sensor 410, and then analyzing the signal through an algorithm to obtain the composition and concentration of the odor gas in the gas to be tested. The data monitored by the odor gas monitoring device is then stored and managed through the data storage module, which is convenient for viewing and analysis. At the same time, the data monitored by the odor gas monitoring device is transmitted to a remote server or data center in real time through the communication module to realize remote monitoring and management. After starting the servo motor 303, it drives the gear 305 to rotate, and the rotation of the gear 305 cooperates with the tooth groove 102 to drive the entire lifting mechanism 3 to rise and fall along the vertical pole 101, and drives the monitoring mechanism 4 to rise and fall during the lifting process. The measuring mechanism 4 monitors the composition and concentration of odorous gases in the air, so that the monitoring mechanism 4 can monitor the odor of the ambient air at different heights, expand the monitoring range, make the monitoring data more accurate and representative, and in the process of lifting and lowering the lifting mechanism 3, the carrying member 301 is lifted and lowered synchronously, and the waterproof cloth 204 is pulled out from the winding box 201 by the carrying member 301, and the front end of the vertical pole 101 is blocked, and the mutual attraction between the magnetic strip 103 and the magnetic strip 205 makes the waterproof cloth 204 close to the vertical pole 101, so as to prevent dust and moisture from penetrating from the gap where the vertical pole 101 and the waterproof cloth 204 meet, pollute and corrode the gear 305 and the tooth groove 102, and cause the operation of the gear 305 to be blocked, and when the waterproof cloth 204 is recovered, the waterproof cloth 204 is rolled up by the spring spring 203, so that the released waterproof cloth 204 can be easily collected into the winding box 201, so as to facilitate the repeated use of the waterproof cloth 204.
