Description

[0001] The utility model relates to the technical field of air quality monitoring, in particular to an online monitoring device for ambient air quality. Background Art

[0002] Ambient air quality online monitoring equipment is a device that monitors outdoor air quality in real time. For example, an air monitor is a monitor that continuously measures the radioactive activity of aerosols, vapors or gases in the air. It is often equipped with an alarm device that will alarm when the radioactive activity exceeds a preset value. The air monitor system is a high-tech product that integrates optical, mechanical, electrical and computer technologies. It uses open optical path differential optical absorption spectroscopy to analyze the concentration of gaseous pollutants and uses an oscillating balance method to measure the concentration of particulate matter. Compared with traditional point instruments, it has the advantages of online continuous measurement, low price, reliable system operation, low operation and maintenance costs, easy installation, and no need for personnel supervision.

[0003] When the air monitor in the prior art is used in low temperature weather, supercooled air enters the gas collection tube. Due to the temperature difference between the cold air and the gas collection tube, the moisture in the cold air condenses into frost. Excessive accumulation of frost in the gas collection tube will cause deviations in the instrument's measurement data and even damage the monitoring instrument. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1 to Figure 5 As shown, the utility model proposes an online monitoring device for environmental air quality, including a protection box 1, an air monitoring system 2, a gas collecting pipe 3, a constant temperature mechanism 4, a moving mechanism 5 and an air supply and drying mechanism 6. The air monitoring system 2 is fixedly connected in the protection box 1, and two gas collecting pipes 3 are provided. The two gas collecting pipes 3 are fixedly connected to the top of the protection box 1, the constant temperature mechanism 4 is fixedly connected to the protection box 1, the moving mechanism 5 is fixedly connected to the bottom of the protection box 1, and the air supply and drying mechanism 6 is fixedly connected to the gas collecting pipe 3. When the equipment is working, the constant temperature mechanism 4 is turned on, and air enters the gas collecting pipe 3 and flows through the constant temperature mechanism 4 to adjust the temperature of the supercooled air and enter the air monitoring system 2 for analysis. At regular intervals, the air supply and drying mechanism 6 is started to blow out the hot air near the constant temperature mechanism 4 to dry the inside of the gas collecting pipe 3. During the process, the supercooled air will not directly enter the air monitoring system 2, thereby protecting the accuracy of the equipment and data.

[0025] Among them, the constant temperature mechanism 4 includes a power supply 7, a heating network 8 and a wire 9. The power supply 7 is fixedly connected in the protective box 1. Two heating networks 8 are provided. The two heating networks 8 are respectively fixedly connected in two gas collecting pipes 3. The wire 9 is fixedly connected between the heating network 8 and the power supply 7. When working, the power supply 7 is started first, and the heating network 8 is turned on through the wire 9 to make the heating network 8 dissipate heat, so that the air is heated to normal temperature air when it enters the gas collecting pipe 3, so as to prevent the air from being too cold and causing the moisture in the air to form frost and affect the measurement results.

[0026] Secondly, the moving mechanism 5 includes a folding plate 10, a rotating shaft 11 and wheels 12. The folding plate 10 is rotatably connected to the bottom end of the protective box 1, the rotating shaft 11 is rotatably connected between the folding plate 10 and the protective box 1, and four wheels 12 are provided. The four wheels 12 are rotatably connected to the folding plate 10. When the equipment needs to be moved, the folding plate 10 is flipped over and the wheels 12 are in contact with the ground, so that the equipment can be pushed with less effort. After moving, the folding plate 10 is flipped over again and the wheels 12 are folded, so that the equipment can be placed more stably on the ground, which greatly improves the freedom of the equipment.

[0027] Again, the air supply drying mechanism 6 includes a worm 13, a worm gear 14, a fan 15 and a motor 16. There are two worms 13, which are respectively rotatably connected to the two gas collecting pipes 3. There are two worm gears 14, which are respectively rotatably connected in the two gas collecting pipes 3. There are two fans 15, which are respectively rotatably connected in the two gas collecting pipes 3. There are two motors 16, which are respectively fixedly connected to the outer walls of the two gas collecting pipes 3. The air supply drying mechanism 6 is used to dry the inner wall of the gas collecting pipe 3. First, the motor 16 is started, and the motor 16 drives the worm 13 to rotate, and the worm 13 drives the worm gear 14 meshing therewith to rotate, and the worm gear 14 drives the fan 15 to rotate, blowing hot air into the gas collecting pipe 3 to dry the inside of the gas drying pipe, thereby preventing water droplets condensed due to temperature difference from entering the air monitoring system 2 and causing equipment failure, thereby having higher safety.

[0028] A partition 17 is provided on the back of the protective box 1 for easy transportation, and a plurality of spring rods 18 are provided inside the partition 17 for shock absorption, so that the device can be tipped over during transportation without worrying about damage due to bumps.
