Description

Technical Field

[0001] This utility model relates to the field of air monitoring technology, specifically to an intelligent lifting air composition monitoring device. Background Technology

[0002] With the acceleration of industrialization, air quality issues have received increasing attention from society. The various components in the air not only directly affect human health, but are also closely related to the ecological environment and climate change. Therefore, monitoring air composition is of paramount importance.

[0003] Current air composition monitoring devices generally have a structure similar to that described in the air quality monitor disclosed in patent application number "CN202020262871.1", encompassing the field of air monitoring. The air quality monitor includes a housing, an air detection sensor, an information acquisition module, a communication module, and a CAN bus transmission module. The housing has an air intake channel. The air detection sensor is located inside the housing and is used to detect the concentration of various components in the air. The information acquisition module converts the concentrations of various components detected by the air detection sensor into electrical signals. The information acquisition module and the communication module communicate via the CAN bus transmission module, and the electrical signals are transmitted to the communication module through the CAN bus transmission module. High-speed CAN bus is used for communication; the CAN bus uses differential signals to resist interference while also ensuring a high sampling rate, thereby improving data accuracy and quality. However, most existing air composition monitoring devices are fixed installations. In complex terrains such as urban building clusters, mountainous areas, and basins, air pollutants are distributed in highly differentiated ways due to the influence of temperature and wind direction. Existing devices can only monitor the air composition of the surrounding local area and cannot cover changes in air composition at different spatial gradients. The monitoring results cannot fully reflect the regional air characteristics.

[0004] Therefore, this invention proposes an intelligent lifting-type air composition monitoring device to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to provide an intelligent lifting-type air composition monitoring device to solve the problem that existing technologies can only monitor air in local areas and cannot reflect the air characteristics of different spatial gradients.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] An intelligent lifting-type air composition monitoring device includes a monitoring platform with an air sampling port. A gas analysis module is installed inside the monitoring platform. The air sampling port is connected to the gas analysis module through a pipe. The air sampling port is connected to a sampling probe. One end of the sampling probe has an air inlet, and the other end of the sampling chamber has an air outlet, which is connected to the air sampling port.

[0008] The monitoring platform has a base at its lower end, and a lifting assembly is provided between the base and the monitoring platform. The lifting assembly includes a lifting rod and a drive motor. The lifting rod includes an inner rod and an outer rod. The inner rod is sleeved inside the outer rod. A guide groove and a guide block are provided between the inner rod and the outer rod. The guide block is slidably connected in the guide groove. The drive motor is fixedly connected to the outer rod. A gear is connected to the output shaft of the drive motor. A rack that meshes with the gear is provided on one side of the inner rod.

[0009] Furthermore, a linear motor is connected between the sampling probe and the monitoring platform. One end of the linear motor is fixedly connected to the monitoring platform, and the other end is connected to the sampling probe. The sampling probe is connected to the air sampling port through a flexible tube, and a corrugated pipe is connected to the outer periphery of the flexible tube.

[0010] Furthermore, a limit switch is provided in the guide groove, the limit switch is connected to the top and bottom of the guide groove, and the limit switch is electrically connected to the drive motor.

[0011] Furthermore, a rain cover is connected to the top of the monitoring platform, and the rain cover is trapezoidal in shape.

[0012] Furthermore, an inspection door is connected to the side of the monitoring platform, and a sealing gasket is provided between the inspection door and the monitoring platform.

[0013] Furthermore, the monitoring platform is equipped with a temperature and humidity sensor and a pressure sensor, both of which are electrically connected to the gas analysis module.

[0014] Furthermore, a wind direction and speed sensor is connected to the monitoring platform, and the wind direction and speed sensor is electrically connected to the gas analysis module.

[0015] In summary, compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. When the drive motor of this utility model is working, it drives the gear to rotate. The gear meshes with the rack, thereby driving the inner rod to move up and down within the outer rod, realizing the lifting and lowering of the entire monitoring platform. To prevent excessive lifting and lowering of the inner rod, a limit switch is installed in the guide groove. The limit switch is connected to the top and bottom of the guide groove and is electrically connected to the drive motor. When the inner rod moves to the top or bottom of the guide groove, the limit switch is triggered, controlling the drive motor to stop working, thus achieving limit protection for the lifting and lowering process. It can drive the sampling probe to move linearly up and down, allowing the sampling probe to sample air at different heights within a local area. The gas analysis module analyzes the air collected at different heights, thus reflecting the air characteristics at different heights in the local area, achieving gradient monitoring of air at different heights in a local area.

[0017] 2. The monitoring platform of this utility model is equipped with a rain cover on its top. The rain cover is trapezoidal in shape and can effectively block rainwater, protecting the equipment inside the monitoring platform from rainwater corrosion. An inspection door is connected to the side of the monitoring platform, and a sealing gasket is installed between the inspection door and the monitoring platform. The sealing gasket ensures the airtightness of the inspection door when closed and facilitates the inspection and maintenance of the internal equipment by personnel. Temperature and humidity sensors, air pressure sensors, and wind direction and speed sensors are also connected to the monitoring platform. These sensors are all electrically connected to the gas analysis module. The temperature and humidity sensors monitor the temperature and humidity information in the environment, the air pressure sensors monitor the air pressure information in the environment, and the wind direction and speed sensors monitor the wind direction and speed information in the environment. This provides the gas analysis module with more comprehensive environmental data and improves the accuracy of air composition monitoring. Attached Figure Description

[0025] like Figure 1-4 As shown, an intelligent lifting air composition monitoring device includes a monitoring platform 1, an air sampling port 2 on the monitoring platform 1, a gas analysis module 3 inside the monitoring platform 1, and the air sampling port 2 connected to the gas analysis module 3 via a pipe. The air sampling port 2 is connected to a sampling probe 5, one end of the sampling probe 5 has an air inlet 6, and the other end of the sampling chamber has an air outlet 7, which is connected to the air sampling port 2. A linear motor 8 is connected between the sampling probe 5 and the monitoring platform 1, one end of the linear motor 8 is fixedly connected to the monitoring platform 1, and the other end is connected to the sampling probe 5. The sampling probe 5 and the air sampling port 2 are connected via a flexible hose 9, and a corrugated pipe 10 is connected to the outer periphery of the flexible hose 9.

[0026] Furthermore, a base 11 is provided at the lower end of the monitoring platform 1. A lifting assembly is provided between the base 11 and the monitoring platform 1. The lifting assembly includes a lifting rod and a drive motor 14. The lifting rod includes an inner rod 15 and an outer rod 16. The inner rod 15 is sleeved inside the outer rod 16. A guide groove 17 and a guide block 18 are provided between the inner rod 15 and the outer rod 16. The guide block 18 is slidably connected in the guide groove 17. The drive motor 14 is fixedly connected to the outer rod 16. A gear 19 is connected to the output shaft of the drive motor 14. A rack 20 that meshes with the gear 19 is provided on one side of the inner rod 15. A limit switch 21 is provided in the guide groove 17. The limit switch 21 is connected to the top and bottom of the guide groove 17 and is electrically connected to the drive motor 14.

[0027] Furthermore, a rain cover 22, trapezoidally shaped, is connected to the top of the monitoring platform 1. An inspection door 23 is connected to the side of the monitoring platform 1, with a sealing gasket 24 between the inspection door 23 and the monitoring platform 1. A temperature and humidity sensor 25 and a pressure sensor 26 are connected to the monitoring platform 1, both electrically connected to the gas analysis module 3. A wind direction and speed sensor 27 is also connected to the monitoring platform 1, electrically connected to the gas analysis module 3.

[0028] The working process of this utility model is as follows:

[0029] First, the device is fixed to the reference position of the target monitoring area by the base 11, which provides a stable support foundation for the entire device. When it is necessary to monitor the air composition at different heights, the drive motor 14 is started, and the output shaft of the drive motor 14 drives the gear 19 to rotate clockwise or counterclockwise. The gear 19 meshes with the rack 20 on the side of the inner rod 15, thereby driving the inner rod 15 to extend and retract vertically within the outer rod 16. The extension length of the inner rod 15 can be precisely adjusted by controlling the number of rotations of the drive motor 14. During the movement of the inner rod 15, the guide block 18 slides synchronously within the guide groove 17. The cooperation between the guide groove 17 and the guide block 18 ensures that the raising and lowering process of the inner rod 15 is smooth and avoids tilting. When the inner rod 15 rises to the top of the guide groove 17 or descends to the bottom of the guide groove 17, the limit switch 21 is triggered, sending a stop signal to the drive motor 14 to prevent excessive movement of the inner rod 15 that could cause mechanical damage.

[0030] The linear motor 8 then drives the sampling probe 5 to move longitudinally. The sampling probe 5 is connected to the air sampling port 2 via a flexible hose 9, and a corrugated pipe 10 is connected to the outer periphery of the flexible hose 9. During the air sampling process, after the sampling probe 5 moves to the target monitoring position, external air enters the sampling chamber through the air inlet 6 at one end of the sampling probe 5, flows along the internal channel of the sampling chamber, and exits from the air outlet 7 at the other end. It is then transported through the flexible hose 9 to the air sampling port 2 of the monitoring platform 1, and finally enters the gas analysis module 3. The temperature and humidity sensor 25 on the monitoring platform 1 collects ambient temperature and humidity data in real time, and the air pressure sensor 26 measures atmospheric pressure. The wind direction and speed sensor 27 is installed on the top of the monitoring platform 1 to monitor the ambient wind direction in real time.

[0031] The trapezoidal rain cover 22 on top of the monitoring platform 1 effectively prevents rainwater from directly wetting the equipment. The trapezoidal structure facilitates rapid water flow and prevents water accumulation. The sealing gasket 24 between the inspection door 23 and the monitoring platform 1 ensures the airtightness of the interior of the cabin.
