Description

Technical Field

[0001] The utility model belongs to the technical field of air pollution detection, and particularly relates to an air pollutant concentration detection device. Background Technique

[0002] Air pollution is a phenomenon in which certain substances enter the atmosphere due to human activities or natural processes, presenting a sufficient concentration, lasting for a sufficient time, and thus harming human comfort, health and welfare or the environment. Air pollutants enter the atmosphere (input) from anthropogenic sources or natural sources, participate in the atmospheric circulation process, and after a certain residence time, are removed from the atmosphere through chemical reactions, biological activities and physical sedimentation in the atmosphere (output). If the output rate is less than the input rate, it will accumulate relatively in the atmosphere, causing the concentration of a certain substance in the atmosphere to increase. When the concentration rises to a certain level, it will directly or indirectly cause acute or chronic harm to people, organisms or materials, etc., and the atmosphere is polluted.

[0003] Currently, when the existing air pollutant concentration detection devices detect the concentration of air pollutants, due to the different weights of different pollutants, they will be distributed at different heights in the air. When detecting the concentration, it is necessary to adjust the height of the detection position to achieve the detection function of different pollutant concentrations. Moreover, for the existing detection devices, generally moving wheels are provided at their bottoms. Using an on-line monitoring device for ambient air pollutant concentration disclosed in CN202122570605.2 and a gas detection device for measuring the instantaneous concentration of air pollutants disclosed in CN202122403878.8, moving wheels are installed at the bottoms of the boxes. Although this improves the mobility of the equipment, since the device is used outdoors, it is not conducive to the stability of the equipment in the case of slopes or rough terrain. Therefore, we propose an air pollutant concentration detection device. Content of the Utility Model

[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-3, the present utility model provides a technical solution for an atmospheric pollutant concentration detection device: including a box body 1, a sleeve 4 and a lifting column 5. The top of the box body 1 is fixedly installed with the sleeve 4 by welding. A screw rod 3 is movably connected inside the sleeve 4 through a bearing. A motor 2 is fixedly installed at the center position of the inner top wall of the box body 1. The end of the output shaft of the motor 2 is fixedly connected to the bottom of the screw rod 3. A lifting column 5 is slidably connected inside the sleeve 4. A threaded groove 11 is opened inside the lifting column 5. The screw rod 3 extends into the threaded groove 11 and is helically connected thereto. Installation rods 6 are fixedly installed on both sides of the top of the lifting column 5. A wind speed and wind direction detector 7, a dust concentration detector 8, an ozone detector 9 and a harmful gas detector 10 are fixedly installed in sequence on the top of the installation rods 6.

[0021] Specifically, universal wheels 22 are provided around the bottom of the box body 1. The universal wheels 22 are fixedly installed around the bottom of the box body 1 through mounting seats. A through groove is opened at the bottom of the box body 1. A positioning cone 21 is provided inside the through groove. An electric push rod 20 is fixedly installed on the inner bottom surface of the box body 1. The bottom of the electric push rod 20 is fixedly connected to the positioning cone 21.

[0022] Specifically, limiting grooves 12 are opened on the surfaces of the inner side walls on both sides inside the sleeve 4. Limiting blocks 13 are fixedly welded on both sides of the bottom end of the lifting column 5. The limiting blocks 13 extend into the limiting grooves 12 and are slidably connected to their inner walls.

[0023] Specifically, transverse level gauges 18 are fixedly installed on both sides of the outer bottom end of the box body 1. A longitudinal level gauge 19 is fixedly installed at the center position of the bottom of the box body 1. Both the transverse level gauge 18 and the longitudinal level gauge 19 are electronic level gauges.

[0024] Specifically, a control panel 15 is fixedly inlaid on the inclined surface on one side of the box body 1. An electric control box 14 is installed inside the box body 1. The electric control box 14 is electrically connected to the control panel 15 through a wire.

[0025] Specifically, a wireless network transceiver 17 is arranged on one side of the inner top wall of the box body 1 close to the control panel 15. The wireless network transceiver 17 is electrically connected to the control panel 15 through a wire.

[0026] Specifically, a push rod 16 is further provided on the side of the box body 1 where the control panel 15 is located. Both ends of the push rod 16 are fixedly connected to the box body 1 by welding.

[0027] In this embodiment, during use, the box body 1 is moved to a suitable site through the push rod 16 and the universal wheels 22. Then, by operating the control panel 15, the electric push rod 20 is actuated to push the positioning cone 21 downward, so that the positioning cone 21 is inserted into the ground, thereby realizing the positioning of the box body 1. At the same time, the transverse level 18 and the longitudinal level 19 are used to judge whether the box body 1 is horizontal, and the extension lengths of the respective electric push rods 20 are automatically adjusted through the control component, so as to ensure that the box body 1 can be in a horizontal state. Finally, the motor 2 drives the screw rod 3 to rotate, which cooperates with the thread groove 11 to drive the lifting column 5 to extend upward, thereby driving the mounting rod 6 and the wind speed and direction detector 7, the dust concentration detector 8, the ozone detector 9 and the harmful gas detector 10 to adjust the height, so as to facilitate the concentration detection of pollutants in the air at different heights. During the height adjustment process, the lifting column 5 is limited by the limiting groove 12 and the limiting block 13, so that the lifting column 5 performs limited sliding lifting inside the sleeve 4, thereby preventing the lifting column 5 from moving with the screw rod 3 and losing the lifting function.
