[0040] Compared with the prior art, the present invention has the following beneficial effects:

[0041] 1. The gas flows into the collecting part through its own fluidity. With the driving of the switching mechanism, the collecting part previously loaded with the gas to be detected rotates to the docking slot opened on the outside of the fixed disk, and the docking slot docks with one of the detection parts. The gas flows from the collecting part through the docking slot into the detection part, and the gas is detected by the detection part.

[0042] 2. When the gas collecting frame rotates to the docking groove opened on the fixed disk, the through groove opened on the outside of the gas collecting frame is aligned with the docking groove. At this time, the sliding plate moves and resets under the action of the second spring, and the gas inside the gas collecting frame is discharged into the detection part to detect the gas. By setting up multiple collection parts, the gas is collected in batches, which improves the accuracy of gas detection and avoids errors.

[0043] 3. Push the cleaning brush to one side of the filter plate to scrape the particles on the filter plate to avoid blocking the filter holes of the filter plate. When the gas collecting frame rotates to the dust cover, the filter plate is downward. When the sliding plate pushes the articulated frame to move, the filtered matter on the filter plate is discharged through the dust cover, thereby ensuring that the gas is filtered in the best state during each gas collection process. At the same time, manual cleaning is avoided and automatic cleaning is performed during each switching process.

[0044] 4. During the rising process of the sleeve, the guide rod fixedly connected on the outside rotates under the limit of the spiral groove opened on the inner side of the limit ring, so that the cleaning pad cleans the outside of the detection probe to ensure the accuracy of the detection probe during the next detection. When the sleeve rises to a certain height, the gas is discharged through the air outlet groove, and the standard gas is used to calibrate the detection probe to ensure that the detection probe is normal before each detection to avoid detection errors.

DETAILED DESCRIPTION

[0059] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0061] like Figures 1 to 12 As shown, an intelligent long-life gas detector includes the following embodiments:

[0062] Embodiment 1: Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the detector housing 1 includes a cover plate 101 disposed on the outer side of the detector housing 1, a mounting frame 2 is fixedly connected to the inside of the detector housing 1, a gas flow pipe 201 for air intake is disposed inside the mounting frame 2, and a dust collecting cover 204 is fixedly connected to the outer side of the mounting frame 2 for displaying gas data of gas detection, and also includes:

[0063] A fixed circular frame 3, the fixed circular frame 3 is fixedly connected to the inside of the installation frame 2, and a connecting pipe 301 is fixedly connected between the fixed circular frame 3 and the gas flow pipe 201, and a rotating cylinder 4 is rotatably connected inside the fixed circular frame 3, and a plurality of collecting parts for gas collection are arranged inside the rotating cylinder 4;

[0064] The fixed disk 7 is fixedly connected to one side of the fixed circular frame 3, and the fixed disk 7 is in contact with one side of the rotating cylinder 4. A docking groove 8041 for gas circulation is provided on the outer side of the fixed disk 7. A connecting disk 801 for gas detection is provided on the side of the fixed disk 7 away from the fixed circular frame 3, and a plurality of detection parts are provided on the outer side of the connecting disk 801;

[0065] The switching mechanism is arranged on one side of the fixed disk 7. When detecting, the switching structure drives the rotating cylinder 4 and the connecting disk 801 to rotate relative to each other, so that the gas inside the multiple collecting parts enters different detection parts through the docking groove 8041 in batches for detection.

[0066] In specific implementation, when the equipment is installed indoors, external gas flows in through the gas circulation pipe 201, and by fixing the connecting pipe 301 between the fixed circular frame 3 and the gas circulation pipe 201, the gas can enter the fixed circular frame 3 through the connecting pipe 301. When testing, by starting the switching structure, the switching mechanism drives the rotating cylinder 4 to rotate, so that the collecting part on the rotating cylinder 4 rotates to the connecting pipe 301. At this time, the gas flows into the collecting part through its own fluidity. With the driving of the switching mechanism, the collecting part previously loaded with the gas to be detected rotates to the docking groove 8041 opened on the outside of the fixed disk 7, and the docking groove 8041 is docked with one of the detection parts. The gas flows from the collecting part through the docking groove 8041 into the detection part, and the gas is detected by the detection part. When the detection is completed, the switching mechanism causes the rotating cylinder 4 and the connecting disk 801 to rotate in opposite directions. At this time, the collecting part with the gas to be detected and the new detection part rotate to the two ends of the docking groove 8041, thereby ensuring that the previous gas will not affect the detection result and ensuring the accuracy of the detection data during each detection.

[0067] In this embodiment, Figure 8 and Fig. 9 As shown, the switching mechanism includes:

[0068] An L-shaped support plate 1003, the L-shaped support plate 1003 is fixedly connected to one side of the fixed plate 7;

[0069] A transmission rod 1006, the transmission rod 1006 passes through the fixed plate 7 and is fixedly connected to the rotating cylinder 4, and one end of the transmission rod 1006 away from the rotating cylinder 4 is fixedly connected to the first bevel gear 1001;

[0070] The third bevel gear 1005 is disposed on the opposite side of the first bevel gear 1001, and the third bevel gear 1005 is fixedly connected to the connecting plate 801 through a support rod, and the support rod passes through the L-shaped support plate 1003 and is rotatably connected to the L-shaped support plate 1003;

[0071] The second bevel gear 1002 is meshed with the first bevel gear 1001 and the third bevel gear 1005 . A driving motor 1004 is fixedly connected to the outer side of the L-shaped support plate 1003 . The output shaft of the driving motor 1004 is fixedly connected to the second bevel gear 1002 .

[0072] In specific implementation, when it is necessary to rotate the rotating cylinder 4 and the connecting disk 801 relative to each other, the driving motor 1004 is started, and the output shaft of the driving motor 1004 drives the second bevel gear 1002 to rotate. The rotation of the second bevel gear 1002 simultaneously drives the first bevel gear 1001 and the third bevel gear 1005 to rotate, so that the first bevel gear 1001 drives the transmission rod 1006, and the transmission rod 1006 drives the fixedly connected rotating cylinder 4 to rotate, thereby achieving the switching of the collecting part, and the third bevel gear 1005 drives the connecting disk 801 to rotate through the support rod, and the connecting disk 801 drives the detection part corresponding to the multiple collecting parts to rotate, so that the collecting part and the detection part are relatively switched.

[0073] Embodiment 2: Figure 5 , Figure 6 and Figure 7 As shown, the collection unit:

[0074] The gas collecting frame 5 is fixedly connected to the inside of the rotating cylinder 4, and an air inlet opening 400 is provided on one side of the gas collecting frame 5, which is used to detect that the gas enters the inside of the gas collecting frame 5 through the air inlet opening 400. A through groove 501 is provided on the outside of the gas collecting frame 5. When the gas collecting frame 5 rotates to the docking groove 8041, the gas flows out through the docking groove 8041;

[0075] The filter plate 502 is fixedly connected to the inside of the gas collecting frame 5 and is used to filter particles in the gas;

[0076] The sliding plate 503 is arranged inside the gas collecting frame 5 and on one side of the filter plate 502. A plurality of telescopic rods 506 and a second spring 507 are fixedly connected between the sliding plate 503 and the gas collecting frame 5. The second spring 507 is sleeved on the outside of the telescopic rod 506.

[0077] The winding disk 504 is arranged outside the rotating drum 4, and the winding disk 504 is connected to the rotating drum 4 through a torsion spring. A traction rope 5051 is wound around the outside of the winding disk 504, and one end of the traction rope 5051 passes through the rotating drum 4 and the gas collecting frame 5 in sequence and is fixedly connected to the sliding plate 503;

[0078] The transmission gear 505 is fixedly connected to one side of the winding disk 504 .

[0079] A fixing ring 202 is fixedly connected to one side of the interior of the installation frame 2 , and two arc-shaped racks 203 are fixedly connected to the outer side of the fixing ring 202 . The two arc-shaped racks 203 are arranged opposite to each other, and the transmission gear 505 is meshed and connected with the arc-shaped racks 203 .

[0080] In specific implementation, when the switching mechanism drives the rotating cylinder 4 to rotate, the gas collecting frame 5 fixedly connected inside the rotating cylinder 4 moves to the connecting pipe 301, and an air inlet opening 400 is provided on the gas collecting frame 5, and the gas enters the gas collecting frame 5 through the air inlet opening 400, and then a sliding plate 503 is provided inside the gas collecting frame 5, and when the gas collecting frame 5 rotates to the connecting pipe 301 along with the rotating cylinder 4, the transmission gear 505 engages with the arc-shaped rack 203, and when the transmission gear 505 engages with the arc-shaped rack 203, the transmission gear 505 drives the winding disk 504 to rotate, and the winding disk 504 drives the traction rope 5051 wound on the outside to be wound, and the traction rope 5051 pulls the sliding plate 503 to move inside the gas collecting frame 5, so that the sliding plate 503 compresses the second spring 507 and the telescopic rod 506, The gas is rushed into the gas collecting frame 5, so as to collect the gas. When the air inlet opening 400 is closed by the fixed circular frame 3, the transmission gear 505 and the arc rack 203 are disengaged from the meshing, and the winding disk 504 is connected to the rotating cylinder 4 by a torsion spring. At this time, the winding disk 504 is reset, and because there is gas inside the gas collecting frame 5, the sliding plate 503 remains stationary. When the gas collecting frame 5 rotates to the docking groove 8041 opened on the fixed disk 7, the through groove 501 opened on the outside of the gas collecting frame 5 is aligned with the docking groove 8041. At this time, the sliding plate 503 moves and resets under the action of the second spring 507, and the gas inside the gas collecting frame 5 is discharged into the detection part, and the gas is detected. By setting up multiple collection parts, the gas is collected in batches, the accuracy of gas detection is improved, and errors are avoided.

[0081] In this embodiment, Figure 6 and Figure 7 As shown, the filter plate 502 is provided with a cleaning member on the outside, and the cleaning member includes:

[0082] Two limiting rods 5022, the two limiting rods 5022 are fixedly connected to the inside of the gas collecting frame 5;

[0083] Two cleaning brushes 5021, the two cleaning brushes 5021 are arranged opposite to each other, and the two ends of the two cleaning brushes 5021 are respectively slidably connected to the outside of the two limiting rods 5022, the outside of the two limiting rods 5022 are sleeved with two first springs 5023, and the two ends of the two first springs 5023 are respectively fixedly connected to the gas collecting frame 5 and the cleaning brush 5021;

[0084] The articulated frame 5026 is rotatably connected to the bottom of the cleaning brush 5021, and a limiting shaft 5027 is fixedly connected to the outer side of the articulated frame 5026. A vertical groove is opened on the outer side of the gas collecting frame 5, and the limiting shaft 5027 extends to the inside of the vertical groove. When the sliding plate 503 pushes the articulated frame 5026, it rises along the vertical groove through the limiting shaft 5027, so that the articulated frame 5026 pushes the cleaning brush 5021 to move to both sides of the gas collecting frame 5.

[0085] The outside of the fixed circular frame 3 is fixedly connected to a dust collecting cover 204 for collecting filtered materials.

[0086] During specific implementation, when the gas enters the gas collecting frame 5 through the connecting pipe 301, the gas contains particulate matter. A large amount of particulate matter affects the subsequent detection part, causing detection errors and damage to the detection part, affecting the normal service life. Therefore, a filter plate 502 is fixedly connected to the inside of the gas collecting frame 5, and the particulate matter is filtered through the filter plate 502. Two cleaning brushes 5021 are arranged on the filter plate 502. Both ends of the bottom of the cleaning brush 5021 pass through the filter plate 502 and are slidably connected to the filter plate 502. In order to ensure the filtering effect of the filter plate 502, elastic sealing sheets are arranged between the two ends of the cleaning brush 5021 and the gas collecting frame 5. When the cleaning brush 5021 compresses the sealing sheet, it prevents the gas from passing through the gap between the cleaning brush 5021 and the filter plate 502. When moving, each time the gas After the body is discharged, the sliding plate 503 rises, and the sliding plate 503 contacts the hinged frame 5026 rotatably connected to the bottom of the cleaning brush 5021, so that the hinged frame 5026 rises, and the limiting shaft 5027 fixedly connected to the outside of the hinged frame 5026 rises linearly along the vertical groove, thereby pushing the cleaning brush 5021 to move to one side of the filter plate 502, scraping the particles in the filter plate 502 to avoid blocking the filter holes of the filter plate 502. When the gas collecting frame 5 rotates to the dust collecting hood 204, the filter plate 502 moves downward, and when the sliding plate 503 pushes the hinged frame 5026 to move, the filtered matter on the filter plate 502 is discharged through the dust collecting hood 204, thereby ensuring that the gas filtration is in the best state during each gas collection process, while also avoiding manual cleaning and automatically cleaning during each switching process.
