Description

Technical Field

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

[0002] The main purpose of air pollution monitoring is to identify pollutants in the atmosphere, understand their distribution and diffusion patterns, monitor the emissions and control of pollution sources, thereby ensuring air quality, preventing air pollution, promoting the development of the environmental protection industry, and raising public awareness of environmental protection. By regularly or continuously monitoring the main pollutants in the atmosphere, it is possible to determine whether air quality meets national air quality standards, providing data for compiling air environmental quality assessment reports. The air pollution monitoring process includes three stages: sampling, analysis, and data processing. Commonly used sampling methods include air filter methods, gas absorption methods, and gas adsorption methods.

[0003] Existing air pollution detection devices have their detection heads directly exposed to the air. After prolonged use, a significant amount of dust accumulates at the intake detection head, especially in windy and dusty environments. Large particles of sand and dust can easily clog the inlet of the intake detection head, affecting the normal operation of the device. To address this, an air pollution detection device is proposed that uses inner and outer filters to filter the air drawn in by the intake detection head, while simultaneously using cleaning cotton to clean the inlet of the intake detection head, thus resolving the aforementioned problems. Utility Model Content

An inner support rod and an outer support rod are fixedly connected to the top of the detector. The inner support rod is located inside the outer support rod. Both the inner and outer support rods have four sets arranged in a cross shape. An inner filter screen is fixedly connected between two sets of inner support rods, and an outer filter screen is fixedly connected between two sets of outer support rods. A top plate is fixedly connected to the top of the inner and outer support rods. A cleaning component is provided at the top of the detector.

A folding rod is fixedly connected to the outer end of the sleeve. A cleaning cotton is fixedly connected to the outer end of the folding rod. The cleaning cotton is inclined.

[0007] Optionally, the aperture of the outer filter screen is larger than that of the inner filter screen. The folding rods are arranged in four groups and are equidistant from each other in a circle.

[0008] Optionally, the cleaning assembly further includes a fixed frame fixedly connected to the outer side of the top of the rotating shaft, a rotating plate fixedly connected to the bottom of the fixed frame, the rotating plate being rotatably connected to the inside of the top plate, a connecting rod fixedly connected to the bottom of the rotating plate, the connecting rod being disposed between the inner filter and the outer filter, and transverse bristles fixedly connected to both sides of the outer end of the connecting rod.

[0009] Optionally, the top end of the rotating shaft passes through the top plate and is fixedly connected to a connecting rod, and the outer end of the connecting rod is fixedly connected to a wind force detection device.

[0014] The working principle and beneficial effects of this utility model are as follows:

[0015] 1. In this utility model, the outer and inner filters filter the gas drawn in by the air intake detection head, preventing large particles from entering the interior of the air intake detection head and thus preventing blockage at the inlet of the air intake detection head.

[0027] Example 1

[0028] Reference Figures 1-3 This is the first embodiment of the present invention, which proposes an air pollution detection device, including a detector 1. An air intake detection head 2 is fixedly connected to the top of the detector 1. An inner support rod 3 and an outer support rod 4 are fixedly connected to the top of the detector 1. The inner support rod 3 is located inside the outer support rod 4. Both the inner support rod 3 and the outer support rod 4 are provided with four sets arranged in a cross shape. An inner filter screen 5 is fixedly connected between two sets of inner support rods 3. An outer filter screen 6 is fixedly connected between two sets of outer support rods 4. A top plate 7 is fixedly connected to the top of the inner support rod 3 and the outer support rod 4. A cleaning component 8 is provided at the top of the detector 1. The cleaning component 8 includes a rotating shaft 801 rotatably connected between the detector 1 and the top plate 7. A sleeve 802 is fixedly connected to the outer end of the rotating shaft 801. A bending rod 803 is fixedly connected to the outer end of the sleeve 802. A cleaning cotton 804 is fixedly connected to the outer end of the bending rod 803. The cleaning cotton 804 is inclined. The purpose of this setup is that during gas detection, the air intake head 2 generates suction, causing external gas to enter the cavity column formed by the four sets of inner support rods 3 through the outer filter 6 and the inner filter 5, thus preventing large particles of impurities from clogging the inlet of the air intake head 2. When the detection equipment is in a windy environment, the rotating shaft 801 drives the outer sleeve 802 to rotate on its own, causing the bending rod 803 at the outer end of the sleeve 802 to rotate inside the cavity column formed by the four sets of inner support rods 3. At this time, the cleaning cotton 804 at the outer end of the bending rod 803 cleans the inlet of the air intake head 2, preventing accumulated dust from affecting the accuracy of the atmospheric detection by the detector 1.

[0029] Optionally, the pore size of the outer filter 6 is larger than that of the inner filter 5. Four sets of folding rods 803 are arranged equidistantly in a circular pattern. The cleaning assembly 8 also includes longitudinal bristles 805 fixedly connected to the bottom of the folding rods 803, with the longitudinal bristles 805 located inside the hollow cylinder formed by the four sets of inner support rods 3. This arrangement aims to facilitate the filtration of impurities of different particle sizes, preventing large particles from entering the air intake detection head 2, since the pore size of the outer filter 6 is larger than that of the inner filter 5. Simultaneously, the rotating folding rods 803 drive the longitudinal bristles 805 to clean the dust at the top of the detector 1, preventing dust accumulation on the top of the detector 1.

[0030] Optionally, the cleaning assembly 8 also includes a fixing frame 806 fixedly connected to the outer side of the top of the rotating shaft 801. A rotating plate 807 is fixedly connected to the bottom of the fixing frame 806. The rotating plate 807 is rotatably connected to the inside of the top plate 7. A connecting rod 808 is fixedly connected to the bottom of the rotating plate 807. The connecting rod 808 is located between the inner filter screen 5 and the outer filter screen 6. Horizontal bristles 809 are fixedly connected to both sides of the outer end of the connecting rod 808. The purpose of this arrangement is that, during the rotation of the rotating shaft 801, the fixing bracket 806 at its outer end drives the rotating plate 807 to rotate inside the top plate 7. At this time, the rotating plate 807 drives the connecting rod 808 at its bottom end to rotate, thereby causing the transverse bristles 809 on both sides of the connecting rod 808 to swing between the inner filter screen 5 and the outer filter screen 6, thereby cleaning the inner filter screen 5 and the outer filter screen 6 respectively, preventing dust and debris from clogging the apertures of the inner filter screen 5 and the outer filter screen 6, thus preventing the air intake effect of the air intake detection head 2 from being affected.

[0031] Optionally, the top end of the rotating shaft 801 passes through the top plate 7 and is fixedly connected to a connecting rod 8010, and the outer end of the connecting rod 8010 is fixedly connected to a wind force detection device 8011. The purpose of this arrangement is that, in a windy environment, the wind force detection device 8011 is rotated by the wind force, thereby causing the rotating shaft 801 to rotate, which in turn drives the bending rod 803 at the outer end of the sleeve 802 and the connecting rod 808 at the bottom end of the rotating plate 807 to rotate, thereby cleaning the air intake detection head 2, the inner filter screen 5 and the outer filter screen 6 respectively.

[0032] Example 2

[0033] Reference Figures 1-5 This is the second embodiment of the present invention, which differs from the first embodiment in that:

[0034] Compared to Embodiment 1, the detector 1 further includes a hollow disc at its top, with a drain hole 9 at the top and a groove at its bottom. A shielding net 10 is fixedly connected inside the groove, and an exhaust fan 11 is fixedly connected to the upper side of the sleeve 802. The exhaust fan 11 is located inside the hollow cylinder formed by the four sets of inner support rods 3. The purpose of this arrangement is that the drain hole 9 facilitates the discharge of cleaned dust from the groove at the bottom of the hollow disc, and the shielding net 10 prevents insects from entering the hollow cylinder formed by the four sets of inner support rods 3. When the sleeve 802 at the outer end of the rotating shaft 801 rotates, the exhaust fan 11 at the outer end of the sleeve 802 rotates, and the generated airflow accelerates the discharge of cleaned dust from the drain hole 9 at the top of the hollow disc.

[0035] Optionally, a lightning rod 12 is snapped onto the top of the connecting rod 8010, and a bolt is threaded between the top of the connecting rod 8010 and the base plate of the lightning rod 12. The purpose of this arrangement is to prevent the detector 1 from being struck by lightning during thunderstorms, thereby preventing damage to the detector 1.

[0036] Optionally, a clamping plate 13 is fixedly connected to the bottom of the detector 1. The clamping plate 13 has symmetrically symmetrically formed grooves inside, and grippers 14 are symmetrically rotatably connected inside the grooves. The inner side of the clamping plate 13 and the cross-section of the grippers 14 are both arc-shaped. Anti-slip pads 15 are fixedly connected to the inner sides of both the clamping plate 13 and the grippers 14. The purpose of this arrangement is that, when installing the detector 1, the clamping plate 13 is snapped onto the outer end of the bracket, and the detector 1 is fixed using two sets of grippers 14. The anti-slip pads 15 enhance the friction between the clamping plate 13, grippers 14, and the bracket, thereby preventing the detector 1 from tilting due to bird strikes or wind, and avoiding any impact on the use of the detector 1.
