Description

Technical Field

[0001] The invention relates to the technical field of air particle pollutant monitoring, and in particular to an atmospheric particle early warning device for air pollution concentration monitoring. Background Art

[0002] As a key indicator of air pollution, atmospheric particulate matter has a profound impact on human health, the ecological environment and climate change. In the process of atmospheric environmental pollution control and prevention, it is necessary to use atmospheric particle early warning devices to monitor and warn of particle pollution in the air environment.

[0003] The prior art (application number: 202311393291.0, Chinese patent with application date of 2023-10-25) discloses an atmospheric environment particulate pollution monitoring device and a monitoring method, which relates to the field of particulate pollution monitoring devices, and solves the problem that catkins, poplar catkins, etc. in the air enter the processing unit and easily affect the detection results. The device includes a vertical pole, an LED display screen, a main unit, a support pole, a wind direction sensor, a temperature and humidity sensor, a wind speed sensor, a processing unit and an air intake unit. Catkins, poplar catkins, and animal hair will float around with the flow of air. When monitoring atmospheric environment particulate matter, the device can effectively prevent the detection of particulate matter. During detection, it is easy for impurities to float into the interior of the processing unit and adhere to the filter belt of the detection, thus affecting the problem of test results. The primary and secondary impurity removal components make the impurity removal effect better and improve the accuracy of the test results. However, although it can scrape off the willow catkins, poplar catkins and animal hair attached to the outside of the filter mechanism during use, the scraping mechanism is prone to adhere to impurities during use, thus affecting the long-term cleaning effect. Moreover, the simple scraping action cannot clean the impurities embedded in the filter holes, which can easily cause blockage and affect normal air suction sampling. There are certain usage defects.

The specific contents are as follows;

[0018] 1. A fixed tube and a movable tube are provided. By starting the motor to drive the gear to rotate, the gear can drive the gear ring to rotate through meshing action, so that the gear ring drives the movable tube to be raised and lowered through the threaded connection structure, so that the sampling head can sample and collect air at different heights, ensuring the comprehensiveness of the equipment monitoring data.

When the sampling is completed, the sealing film will move up and reset, thereby driving the cutting piece to reset, so as to cut the impurities stuck in the filter holes and ensure that the impurities on the outside of the filter can fall off.

[0020] 3. A rotating rod and an elastic membrane are provided. As the movable tube moves upward, the first pull rope will pull the winding wheel to rotate, so that the magnetic block on the winding wheel intermittently passes through the outside of the magnetic block on the movable ring, so that the movable ring can be elastically raised and lowered under the action of magnetic force. At this time, the movable ring will pull multiple rotating rods through the connecting rod to perform synchronous elastic rotation. At this time, the elastic membrane on the outside of the rotating rod can promote the flow of air outside the sampling head through the action of air pressure, thereby expanding the area range of the sampling head.

[0021] 4. A knocking piece and an elastic airbag are provided. When the rotating rod is reset, the knocking piece on its outer side can knock the filter to achieve auxiliary cleaning of the filter. When the movable tube moves down and resets, the movable plate will squeeze the elastic airbag, so that the air pressure inside the elastic airbag gradually increases. When the pressure reaches the threshold, the exhaust pipe automatically opens to supply air to the fixed tube, thereby achieving flushing of the inner walls of the fixed tube and the movable tube. At the same time, the air pressure inside the sampling head increases, causing the sealing film to move up, thereby driving the cutting disc to rotate in the opposite direction, and releasing the blockage of the filter again, thereby blowing off the impurities attached to the outside of the filter in the opposite direction, effectively avoiding blockage of the filter during long-term use.

[0035] The driving assembly includes a motor 7 fixedly mounted on the inner side of the first mounting seat 6, and a gear 8 is fixedly mounted on the output end of the motor 7, and a gear ring 9 is rotatably connected to the upper end of the fixed tube 3, and the gear ring 9 and the gear 8 are meshed and connected, the outer wall of the movable tube 4 and the inner wall of the gear ring 9 are respectively provided with threaded structures, and the movable tube 4 and the gear ring 9 are threadedly connected, and a slider 10 is symmetrically arranged on the outer side of the lower end of the movable tube 4, and a slide groove is provided on the inner wall of the fixed tube 3, and the slider 10 is vertically slidably adjusted in the slide groove.

[0036] The cleaning component includes a sealing film 12 which is sealed to the upper inner wall of the sampling head 5, and a spring is fixedly connected between the sealing film 12 and the upper inner wall of the sampling head 5, and the sealing film 12 is raised and lowered under the action of the change of air pressure inside the sampling head 5, and a lifting ring 13 is fixedly connected to the lower end of the sealing film 12, and a ball 1301 is embedded and installed on the outer wall of the lifting ring 13, and a rotating ring 14 is elastically rotatably installed on the inner wall of the sampling head 5, and a spiral guide groove 1401 is opened on the inner wall of the rotating ring 14, and during the lifting and lowering adjustment process of the lifting ring 13, the ball 1301 rolls along the guide groove 1401 to drive the rotating ring 14 to rotate and adjust.

[0037] A cutting blade 15 is evenly installed at the lower end of the rotating ring 14, and the cutting blade 15 is sharpened on both sides, and the cutting blade 15 slides against the inner wall of the filter screen 11 to cut impurities that pass through the filter hole, and at the same time, the cutting blade 15 blocks the filter hole of the filter screen 11 in the initial state, and a winding wheel 16 is arranged below the movable ring 19, and the winding wheel 16 is elastically rotatably installed on the upper outer side of the movable tube 4 through a vortex spring, and a first pull rope 17 is wound around the outer side of the winding wheel 16, and at the same time, the lower end of the first pull rope 17 is fixedly connected to the outer side of the first mounting seat 6, and the movable tube 4 moves upward during the process. The first pull rope 17 pulls the winding wheel 16 to rotate elastically. Magnetic blocks 20 are embedded and installed on the opposite surfaces of the winding wheel 16 and the movable ring 19, and the magnetic poles of the opposite surfaces of the two groups of magnetic blocks 20 are the same, and the initial positions of the two groups of magnetic blocks 20 are staggered. At the same time, a fixed ring 18 is connected to the top of the movable ring 19 through a spring, and the fixed ring 18 is fixedly installed on the upper outer side of the movable tube 4. During the elastic lifting process of the movable ring 19, the connecting rod 21 drives multiple rotating rods 22 to rotate elastically, and during the rotation of the rotating rod 22, the elastic membrane 23 drives the air flow near the sampling head 5.

[0038] By adopting the above technical solution, when it is necessary to sample and collect air in areas at different heights, the fan inside the device body 1 is started to generate negative pressure in the fixed tube 3 and the movable tube 4. At this time, negative pressure is generated inside the sampling head 5 at the same time, so that the sealing film 12 moves down along the inner side of the sampling head 5 under the action of the negative pressure, thereby driving the lifting ring 13 at the lower end of the sealing film 12 to move down synchronously, so that the ball 1301 set on the outer wall of the lifting ring 13 rolls along the guide groove 1401, thereby driving the rotating ring 14 to rotate, so that the cutting piece 15 at the lower end of the rotating ring 14 releases the blockage of the filter 11, ensuring that the filter 11 can normally inlet air, and realizing air sample collection, and at the same time starting the motor 7, so that the motor 7 drives the gear 8 at its output end to rotate synchronously , so that the gear 8 drives the gear ring 9 to rotate synchronously through meshing. At this time, the inner wall of the gear ring 9 will be threadedly connected with the movable tube 4, thereby driving the movable tube 4 to be raised and lowered on the inner side of the fixed tube 3. As the movable tube 4 moves upward, the first pull rope 17 pulls the winding wheel 16 to rotate, so that the winding wheel 16 rotates elastically. At this time, the magnetic block 20 on the outside of the winding wheel 16 will intermittently pass through the magnetic block 20 on the outside of the movable ring 19, so that the movable ring 19 is reciprocated and elastically raised and lowered under the action of magnetic force. At this time, the movable ring 19 will drive multiple rotating rods 22 to reciprocate through the connecting rod 21. At this time, the elastic membrane 23 on the outside of the rotating rod 22 can fan the air and accelerate the air flow near the sampling head 5, further expanding the sampling range of the sampling head 5.

[0039] Embodiment 2: The technical content disclosed in this embodiment is a further improvement on the above embodiment 1. The existing atmospheric particle warning device has a single cleaning method for the filter mechanism and cannot fully clean the impurities stuck in the filter holes. In order to further solve this technical problem, this embodiment discloses the following technical content, such as Figure 4-Figure 10 As shown; a base 26 is fixedly provided on the outer side of the fixed tube 3, and a movable plate 27 is provided on the inner side of the base 26 for lifting, and a recoil cleaning component for flushing the pipeline is connected between the movable plate 27 and the base 26.

[0040] A knocking piece 24 is fixedly installed on the outer side of the rotating rod 22, and the knocking piece 24 knocks the filter 11 during the rotation of the rotating rod 22. The recoil cleaning assembly includes an elastic air bag 28 connected between the movable plate 27 and the base 26, and the movable plate 27 and the inner wall of the upper end of the base 26 are fixedly connected with a spring, and the upper end of the elastic air bag 28 is fixedly connected with a second pull rope 25, and the upper end of the second pull rope 25 is connected to the outer side of the fixed ring 18. At the same time, a purifier 29 is also fixedly installed on the outer side of the base 26, and an intake pipe 30 is fixedly installed on the upper end of the purifier 29, and an air supply pipe 31 is connected between the purifier 29 and the elastic air bag 28, and an exhaust pipe 32 is connected between the elastic air bag 28 and the fixed pipe 3, a one-way valve structure is provided on the air supply pipe 31, and a pressure valve is provided on the exhaust pipe 32.

[0041] By adopting the above technical solution, when sampling, as the movable tube 4 moves upward, the fixed ring 18 will pull the movable plate 27 to move upward on the inner side of the base 26 through the second pull rope 25, so that the movable plate 27 stretches the elastic airbag 28, so that the elastic airbag 28 extracts the filtered clean air through the suction pipe 30 and the air delivery pipe 31, and when the sampling test is completed, the sealing film 12 will be reset, so that the cutting piece 15 will cut the impurities stuck in the filter holes of the filter screen 11 during the synchronous reset process, so as to facilitate the subsequent cleaning of the impurities stuck on the filter screen 11, and then the movable tube 4 is controlled to move downward. At this time, the movable plate 27 will move downward under the action of the spring force, thereby squeezing the elastic airbag 28, so that the elastic airbag 28 is inside. When the air pressure rises and exceeds the threshold of the pressure valve in the exhaust pipe 32 (the pressure threshold of the pressure valve in the exhaust pipe 32 is greater than the pressure threshold required for the sealing film 12 to move), the compressed gas in the elastic airbag 28 enters the fixed tube 3 through the exhaust pipe 32, thereby realizing backwashing of the fixed tube 3 and the movable tube 4, avoiding the influence of sampling residues on subsequent detection results. At the same time, the air pressure inside the sampling head 5 rises, so that the sealing film 12 drives the lifting ring 13 to move upward, thereby driving the rotating ring 14 to rotate again, so that the cutting blade 15 can release the blockage of the filter 11 again, so that the air can be blown out through the filter 11, thereby blowing off the debris attached to the outside of the filter 11, effectively improving the cleaning effect of the filter 11.
