DETAILED DESCRIPTION

[0015] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0016] Depend on Figure 1-8 gives: The present invention relates to a carbon emission air quality monitor device, comprising a housing 1, filter screens 2 are fixedly arranged at both ends of the housing 1, an annular plate 3 is fixedly arranged inside the housing 1, a gas sensor 4 is fixedly arranged on the annular plate 3, a rotating shaft 5 is rotatably arranged between two filter screens 2, an air intake fan blade 6 and an exhaust fan blade 7 are fixedly arranged at both ends of the rotating shaft 5, and a driving motor 8 for driving the rotating shaft 5 to rotate is fixedly arranged on one of the filter screens 2; With such a design, when in use, the carbon emission air quality monitor device is placed at a place that needs to be monitored, and the rotating shaft 5 can be driven to rotate by the driving motor 8, and the air intake blades 6 and the exhaust blades 7 are driven to rotate by the rotating shaft 5 respectively, so that the outside air enters the interior of the shell 1 through the air intake blades 6, and the gas in the air is detected by the gas sensor 4 in the detector in the shell 1, and then the air in the shell 1 is discharged through the exhaust blades 7 to realize the monitoring process, wherein the setting of the filter 2 can filter the dust in the air.

[0017] Considering that after a long period of use, a lot of dust will adhere to the surface of the gas sensor 4, which is easy to reduce the monitoring accuracy of the gas sensor 4, in order to solve this problem, an annular groove 9 is provided inside the annular plate 3, and an electromagnetic mechanism is provided in the annular groove 9. A dust removal mechanism is rotatably provided on the rotating shaft 5 near the annular plate 3. The dust removal mechanism includes a sensor dust removal assembly, and the sensor dust removal assembly includes a column 10 rotatably provided on the rotating shaft 5. The column 10 is evenly provided with mounting grooves 11. A mounting block 12 is slidably provided inside the mounting groove 11. A telescopic spring 28 is provided between the mounting block 12 and the mounting groove 11. Two arc plates 13 and a sensor cleaning brush 14 are also fixedly provided on the mounting block 12. The two arc plates 13 are distributed on both sides of the sensor cleaning brush 14, and the arc plates 13 cooperate with the electromagnetic mechanism through magnetic adsorption; With such a design, when it is necessary to clean the dust attached to the gas sensor 4, the electromagnetic mechanism generates magnetic force to adsorb the arc plate 13, so that the arc plate 13 moves toward the direction close to the annular plate 3. During this period, the arc plate 13 drives the mounting block 12 to move, so that the mounting block 12 squeezes the telescopic spring 28, and the mounting block 12 drives the sensor cleaning brush 14 thereon to gradually approach the gas sensor 4. When the column 10 drives the sensor cleaning brush 14 thereon to rotate, the dust on the gas sensor 4 can be cleaned by the rotated sensor cleaning brush 14.

[0018] There are four mounting grooves 11 and four mounting blocks 12. The arc-shaped plates 13 on the two mounting blocks 12 distributed in the horizontal direction are provided with arc-shaped grooves 15 inside. The arc-shaped grooves 15 are slidably matched with the corresponding arc-shaped plates 13 on the two mounting blocks 12 distributed in the vertical direction. Such a design can make the multiple arc plates 13 after being unfolded roughly form an annular enclosure. At the same time, when in use, the electromagnetic mechanism will also extend out and contact the enclosure, thereby forming an annular space between the multiple arc plates 13 and the electromagnetic mechanism, preventing dust from other areas from entering the annular space where the gas sensor 4 is located.

[0019] The electromagnetic mechanism includes a plurality of crescent plates 16 distributed along the circumference of the annular plate 3 and having an electromagnet inside. Two adjacent crescent plates 16 are fixed by an arc-shaped elastic pad 17. Each crescent plate 16 is fixed by a symmetrically arranged elastic rope 18 and an annular groove 9, and a breathable valve 19 is fixedly embedded on each crescent plate 16. The arc plate 13 is made of a magnetic material, and the arc plate 13 and the electromagnet inside the crescent plate 16 are magnetically adsorbed and matched. With such a design, when the electromagnet in the crescent plate 16 is energized to generate magnetism, the crescent plate 16 and the arc plate 13 are brought close to each other under the action of the magnetic force, thereby forming an annular space through multiple crescent plates 16, elastic pads 17, and multiple arc plates 13, so that the gas sensor 4 is located in the annular space.

[0020] Considering that the inner wall of the housing 1 will be covered with a lot of dust after long-term use, in order to solve this problem, the dust removal mechanism also includes two inner wall dust removal components for cleaning the inner wall of the housing 1. The two inner wall dust removal components are distributed on both sides of the sensor dust removal component and are fixedly arranged with the sensor dust removal component. With such a design, when in use, the rotating shaft 5 will drive the inner wall dust removal component to move, and the dust on the inner wall of the shell 1 will be cleaned by the inner wall dust removal component.

[0021] The inner wall dust removal assembly includes a mounting frame 20 rotatably arranged on the rotating shaft 5, and the mounting frame 20 is fixedly arranged with the I-shaped column 10, and the shape of the mounting frame 20 is U-shaped, and an inner wall cleaning brush 21 is fixedly arranged on the side of the mounting frame 20 close to the inner wall of the shell 1, and a filter cleaning brush 22 is fixedly arranged on the side of the mounting frame 20 close to the filter 2; wherein a rack 23 is arranged on the mounting frame 20, and a gear 24 is fixedly arranged on the rotating shaft 5, and the rack 23 is meshed with the gear 24, and a hydraulic driver for driving the rack 23 to move is arranged inside the column 10; With this design, when the arc plate 13 drives the mounting block 12 to move, the mounting block 12 moves the rack 23 through the hydraulic driver and then engages with the gear 24. At this time, when the rotating shaft 5 rotates, the rotating shaft 5 can drive the mounting frame 20 to rotate through the gear 24 and the rack 23 in sequence, and the mounting frame 20 drives the inner wall cleaning brush 21 and the filter cleaning brush 22 thereon to rotate, so that the inner wall cleaning brush 21 cleans the dust on the inner wall of the shell 1, and the filter cleaning brush 22 cleans the dust on the filter 2.

[0022] Specifically, the hydraulic driver includes two hydraulic rods 25, wherein the first hydraulic rod 25 is arranged in the mounting groove 11 in the column 10, the bottom end of the first hydraulic rod 25 is fixedly arranged with the corresponding mounting block 12, the top end of the first hydraulic rod 25 is fixedly arranged with the mounting groove 11, the second hydraulic rod 25 is fixedly arranged on the mounting frame 20 and fixedly arranged with the rack 23, the interior of the mounting frame 20 is provided with a through hole 26, and the interior of the first hydraulic rod 25 and the interior of the second hydraulic rod 25 are respectively fixedly connected with the two ends of the through hole 26 through a conduit; With such a design, when the mounting block 12 moves, the first hydraulic rod 25 is squeezed to shrink, and the hydraulic oil in the first hydraulic rod 25 enters the interior of the second hydraulic rod 25 through the through hole 26, so that the second hydraulic rod 25 extends. The second hydraulic rod 25 drives the rack 23 to move and meshes with the gear 24 to realize the driving process.

[0023] Specifically, two ends of the mounting frame 20 close to the rotating shaft 5 are fixedly provided with integral connecting rings 27 , and the two connecting rings 27 are rotatably matched with the rotating shaft 5 .

[0024] Working principle: This device has two operating states. The first operating state is the conventional low-speed monitoring state. The specific process is as follows: The rotating shaft 5 is driven to rotate by the driving motor 8, and the air intake blades 6 and the exhaust blades 7 are driven to rotate by the rotating shaft 5 respectively, so that the outside air enters the interior of the housing 1 through the air intake blades 6, and the gas in the air is detected by the gas sensor 4 in the detector in the housing 1, and then the air in the housing 1 is discharged through the exhaust blades 7 to realize the monitoring process, wherein the setting of the filter 2 can filter the dust in the air; The second operating state is an unconventional high-speed dust removal state, and the specific process is as follows: First, the electromagnet in the crescent plate 16 in the electromagnetic mechanism is energized, and the electromagnet generates magnetism to attract the magnetic arc plate 13, so that the crescent plate 16 and the arc plate 13 are close to each other, and the arc plate 13 also drives the mounting block 12 to move. During the movement, one of the mounting blocks 12 squeezes and contracts the first hydraulic rod 25 in the mounting groove 11. Under the pressure transmission of the liquid, the hydraulic oil in the first hydraulic rod 25 enters the second hydraulic rod 25 on the mounting frame 20 through the through hole 26 and stretches it, so that the second hydraulic rod 25 drives the rack 23 to mesh with the gear 24. Secondly, the rotating shaft 5 is driven to rotate by the driving motor 8, and the rotating shaft 5 drives the mounting frame 20 to rotate in turn through the gear 24 and the rack 23, so that the dust on the inner wall of the shell 1 and the dust on the filter 2 can be cleaned by the inner wall cleaning brush 21 and the filter cleaning brush 22 on the mounting frame 20 respectively; at the same time, the mounting frame 20 will also drive the column 10 to rotate, and under the action of centrifugal force and magnetic force, the mounting block 12 extends out of the mounting groove 11, and the mounting block 12 drives the arc plate 13 to move, so that the multiple arc plates 13 are unfolded, and at the same time, under the action of magnetic force, the crescent plate 16 will also extend out of the annular groove 9 After that, it contacts with the arc plate 13, thereby forming an annular space for isolating the gas sensor 4 during the dust removal process through the crescent plate 16 and the arc plate 13. At this time, the dust on the filter screen 2 and the dust on the inner wall of the shell 1 will be discharged through the space between the column 10 and the arc plate 13 after cleaning, and will not enter the annular space where the gas sensor 4 is located. The sensor cleaning brush 14 on the mounting block 12 will clean the dust on the gas sensor 4 during the rotation process. At this time, the annular space is inlet through the air permeable valve 19, so that the dust cleaning of the two does not affect each other, so as to improve the cleaning effect; Finally, after the dust is cleaned, the drive motor 8 is turned off, and under the action of the telescopic spring 28, the mounting block 12 returns to its original position. At this time, the first hydraulic rod 25 extends and the second hydraulic rod 25 contracts, so that the rack 23 and the gear 24 are disengaged, so that the mounting frame 20 and the column 10 no longer rotate, and the conventional low-speed monitoring state can be entered.
