Description

Technical Field

[0001] This utility model relates to the field of sampling probe technology, specifically a sampling probe for flue gas monitoring. Background Technology

[0002] Many factories generate a lot of flue gas during production. When emitting, they need to comply with relevant emission standards. Before emission, the flue gas needs to be monitored. The existing flue gas emission monitoring sampling probes can basically meet the daily needs, but there are still some shortcomings that need to be improved.

[0003] Publication number CN221280737U discloses a sampling probe for flue gas emission monitoring. When using the sampling probe, the top cover can be rotated to the flue gas collection hole, allowing the flue gas collection hole to be exposed to the outside world and effectively monitor flue gas emissions. However, this patent still has the following problems in actual use:

[0004] When using the sampling probe, the top cover can be rotated to the flue gas collection hole, exposing the flue gas collection hole to the outside world, allowing the flue gas collection hole to effectively monitor flue gas emissions. However, there is no screen installed at the flue gas collection hole, which allows dust in the flue gas to directly enter the probe through the flue gas collection hole, resulting in a large amount of dust adhering to the probe surface, thus reducing the accuracy of flue gas monitoring.

[0005] A sampling probe for flue gas monitoring is proposed to address the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide a sampling probe for flue gas monitoring, in order to solve the problem mentioned in the background art. Currently, when using a sampling probe, the top cover can be rotated to the flue gas collection hole to expose the flue gas collection hole to the outside world, allowing the flue gas collection hole to effectively monitor flue gas emissions. However, no screen is installed at the flue gas collection hole, which allows dust in the flue gas to directly enter the probe through the flue gas collection hole, resulting in a large amount of dust adsorbed on the probe surface, thus reducing the accuracy of flue gas monitoring.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a sampling probe for flue gas monitoring, comprising a body, a protective plate, and a screen, wherein the top surface of the body is fixedly connected to the protective plate;

[0008] A drive motor is fixedly installed in the middle of the top surface of the protective plate. A smoke inlet is opened on the surface of the protective plate. Several locking grooves are symmetrically opened on both sides of the smoke inlet. Several connectors are symmetrically installed on both sides of the screen. A locking rod is connected through the inside of the connector. The locking rod is engaged with the locking groove.

[0009] Also includes:

[0010] Several stabilizing plates are fixedly installed on the surface of the protective plate;

[0011] Among them, the internal part of the stabilizing plate is connected by a limit rod;

[0012] The surface of the limiting rod is fitted with a compression spring.

[0013] Preferably, a bonding plate is fixedly connected to one side surface of the compression spring, and the other side surface of the compression spring is fixedly connected to a stabilizing plate, with the limiting rod penetratingly connected to the bonding plate.

[0014] Preferably, the surface of the bonding plate away from the compression spring is bonded to the connector.

[0015] Preferably, a connecting rod is fixedly connected to one side surface of the drive motor output end that passes through the protective plate, a connecting plate is fixedly connected to the bottom surface of the connecting rod, and a fixing rod is fixedly connected to the bottom surface of the connecting plate.

[0016] Preferably, a perforated plate is fixedly connected to the bottom surface of the fixing rod, the bottom surface of the perforated plate is rotatably connected to the body, and the two sides of the perforated plate are fitted and connected to the protective plate.

[0017] Preferably, a baffle is connected through one side surface of the protective plate, a plurality of mounting parts are fixedly installed on the surface of the baffle, a fixing bolt is fixedly installed on the surface of the mounting parts, and a cleaning sticker is adhesively connected to one side surface of the baffle.

[0018] Preferably, a limiting groove is formed on one side of the surface of the locking rod, and the limiting groove is engaged with the limiting rod.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: This sampling probe for flue gas monitoring, by setting a locking groove, a screen, a connecting piece, a locking rod, a stabilizing plate, a limiting rod, a compression spring, a fitting plate, and a limiting groove, can filter dust in the flue gas, thereby reducing dust from entering the interior of the probe and preventing dust from affecting the probe. Simultaneously, by setting a drive motor, a connecting rod, a connecting plate, a fixing rod, and a perforated plate, when the probe is not in use, the perforated plate is offset from the flue gas inlet, thus preventing flue gas from entering the interior of the probe. The specific details are as follows:

[0020] 1. By setting up a locking groove, screen, connector, locking rod, stabilizing plate, limiting rod, compression spring, bonding plate, and limiting groove, when the screen needs to be disassembled and cleaned after long-term use, pulling the limiting rod allows the bonding plate to move. The movement of the bonding plate compresses the compression spring, causing it to deform. After the limiting rod is pulled to a certain position, it separates from the limiting groove, allowing the screen to be disassembled and cleaned. During screen installation, after the locking rod on the screen engages with the locking groove, loosening the limiting rod allows the sliding plate to return to its original position under the action of the compression spring. The sliding plate and limiting rod are fixedly connected, so when the sliding plate returns to its original position, it also moves the limiting rod back to its original position, thus engaging the limiting rod with the limiting groove, completing the screen installation.

[0021] 2. By setting up a drive motor, connecting rod, connecting plate, fixing rod, and perforated plate, when the main body is not in use, the drive motor is started through the control terminal, so that the output end of the drive motor drives the connecting rod to rotate. The rotation of the connecting rod drives the connecting plate to rotate. The rotation of the connecting plate drives the fixing rod to rotate. The rotation of the fixing rod drives the perforated plate to rotate. Thus, the perforated plate is misaligned with the smoke inlet, thereby preventing smoke from entering the interior of the main body.

[0022] 3. By setting up a baffle, mounting parts, fixing bolts, and a cleaning sticker, when the perforated plate rotates, it rotates to the position of the cleaning sticker, allowing the cleaning sticker to adhere to the dust on the perforated plate, thereby preventing clogging. When disassembling the cleaning sticker, the fixing bolts are used to separate it from the protective plate and the main body, making it easy to replace. When installing the baffle, one side of the baffle is engaged with one side of the protective plate, and the fixing bolts secure the baffle to the protective plate and the main body, thus facilitating subsequent cleaning of the perforated plate surface.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-5 This utility model provides a technical solution: a sampling probe for flue gas monitoring, including a body 1, a protective plate 2, and a screen 6. The top surface of the body 1 is fixedly connected to the protective plate 2; a drive motor 3 is fixedly installed in the middle of the top surface of the protective plate 2; a smoke inlet 4 is opened on the surface of the protective plate 2, and several locking grooves 5 are symmetrically opened on both sides of the smoke inlet 4; several connecting pieces 7 are symmetrically installed on both sides of the screen 6, and a locking rod 8 is connected through the inside of the connecting piece 7, and the locking rod 8 is engaged with the locking groove 5; it also includes: several stabilizing plates 17 are fixedly installed on the surface of the protective plate 2; wherein, a limiting rod 18 is connected through the inside of the stabilizing plate 17; wherein, a compression spring 19 is sleeved on the surface of the limiting rod 18, such as Figure 1-5 As shown, by setting the locking groove 5, screen 6, connector 7, locking rod 8, stabilizing plate 17, limiting rod 18, compression spring 19, bonding plate 20 and limiting groove 21, the dust in the flue gas can be filtered, thereby reducing the amount of dust entering the interior of the main body 1 and avoiding the impact of dust on the main body 1. At the same time, by setting the drive motor 3, connecting rod 9, connecting plate 10, fixing rod 11 and perforated plate 12, when the main body 1 is not in use, the perforated plate 12 is offset from the smoke inlet 4, thereby preventing the flue gas from entering the interior of the main body 1.

[0031] A bonding plate 20 is fixedly connected to one side surface of the compression spring 19, and a stabilizing plate 17 is fixedly connected to the other side surface of the compression spring 19. A limiting rod 18 is connected through the bonding plate 20. The side surface of the bonding plate 20 away from the compression spring 19 is bonded to the connecting piece 7. Figure 4 As shown, when the screen 6 needs to be disassembled and cleaned after prolonged use, pulling the limiting rod 18 causes the bonding plate 20 to move. This movement of the bonding plate 20 compresses the compression spring 19, causing it to deform. Simultaneously, after the limiting rod 18 is pulled to a certain position, it separates from the limiting groove 21. Then, by pulling the screen 6, the locking rod 8 on the screen 6 separates from the locking groove 5. This allows the screen 6 to be disassembled and cleaned. When installing the screen 6, after the locking rod 8 on the screen 6 is engaged with the locking groove 5, the limiting rod 18 is loosened, allowing the slide plate to return to its original position under the action of the compression spring 19. The slide plate and the limiting rod 18 are fixedly connected through the screen, so when the slide plate returns to its original position, it can also drive the limiting rod 18 to return to its original position, thereby engaging the limiting rod 18 with the limiting groove 21, thus completing the installation of the screen 6.

[0032] A connecting rod 9 is fixedly connected to one side surface of the protective plate 2 through the output end of the drive motor 3. A connecting plate 10 is fixedly connected to the bottom surface of the connecting rod 9. A fixing rod 11 is fixedly connected to the bottom surface of the connecting plate 10. A perforated plate 12 is fixedly connected to the bottom surface of the fixing rod 11. The bottom surface of the perforated plate 12 is rotatably connected to the body 1. Both sides of the perforated plate 12 are fitted and connected to the protective plate 2. Figure 3 As shown, the drive motor 3 is started by the control terminal, which causes the output of the drive motor 3 to drive the connecting rod 9 to rotate. The rotation of the connecting rod 9 causes the connecting plate 10 to rotate. The rotation of the connecting plate 10 causes the fixing rod 11 to rotate. The rotation of the fixing rod 11 causes the perforated plate 12 to rotate. This causes the perforated plate 12 to be misaligned with the smoke inlet 4, thereby preventing smoke from entering the interior of the main body 1.

[0033] A baffle 13 is connected through one side surface of the protective plate 2. Several mounting parts 14 are fixedly installed on the surface of the baffle 13, and fixing bolts 15 are fixedly installed on the surface of the mounting parts 14. A cleaning sticker 16 is adhesively connected to one side surface of the baffle 13. Figure 3 , 5As shown, when the perforated plate 12 rotates, it rotates to the cleaning sticker 16. At this point, the cleaning sticker 16 can adhere to the dust on the perforated plate 12, thereby preventing the perforated plate 12 from becoming clogged. At the same time, when disassembling the cleaning sticker 16, it is easy to replace the cleaning sticker 16 by separating it from the protective plate 2 and the main body 1 by fixing bolt 15. When installing the baffle 13, one side of the baffle 13 is engaged with one side of the protective plate 2, and the baffle 13 is installed on the protective plate 2 and the main body 1 by fixing bolt 15. This makes it easier to clean the surface of the perforated plate 12 with the cleaning sticker 16.

[0034] A limiting groove 21 is formed on one side of the surface of the locking rod 8, and the limiting groove 21 is engaged with the limiting rod 18, such as... Figure 4 As shown, the screen 6 can be installed by engaging the limiting groove 21 with the limiting rod 18.

[0035] Working principle: Before using this type of flue gas monitoring sampling probe, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 5 As shown, the system first includes a locking groove 5, a screen 6, a connector 7, a locking rod 8, a stabilizing plate 17, a limiting rod 18, a compression spring 19, an adhesive plate 20, and a limiting groove 21. When the screen 6 needs to be disassembled and cleaned after prolonged use, pulling the limiting rod 18 causes the adhesive plate 20 to move. This movement of the adhesive plate 20 compresses the compression spring 19, causing it to deform. Simultaneously, after the limiting rod 18 is pulled to a certain position, it separates from the limiting groove 21, allowing the screen to... By pulling the screen 6, the locking rod 8 on the screen 6 is separated from the locking groove 5, which allows the screen 6 to be disassembled and cleaned. At the same time, when installing the screen 6, after the locking rod 8 on the screen 6 is engaged with the locking groove 5, the limiting rod 18 is loosened, which allows the slide plate to return to its original position under the action of the compression spring 19. At the same time, the slide plate and the limiting rod 18 are fixedly connected through, so when the slide plate returns to its original position, it can also drive the limiting rod 18 to return to its original position, thereby engaging the limiting rod 18 with the limiting groove 21, thus completing the installation of the screen 6.

[0036] Secondly, by setting up a drive motor 3, a connecting rod 9, a connecting plate 10, a fixing rod 11, and a perforated plate 12, when the main body 1 is not in use, the drive motor 3 is started through the control terminal, so that the output end of the drive motor 3 drives the connecting rod 9 to rotate. The rotation of the connecting rod 9 drives the rotation of the connecting plate 10, which in turn drives the rotation of the fixing rod 11. The rotation of the fixing rod 11 then drives the rotation of the perforated plate 12. This causes the perforated plate 12 to be misaligned with the smoke inlet 4, thereby preventing smoke from entering the interior of the main body 1.

[0037] Finally, by setting up the baffle 13, mounting part 14, fixing bolt 15, and cleaning sticker 16, when the perforated plate 12 rotates, the perforated plate 12 rotates to the position of the cleaning sticker 16, so that the cleaning sticker 16 can stick to the dust on the perforated plate 12, thereby preventing the perforated plate 12 from becoming clogged. At the same time, when disassembling the cleaning sticker 16, the fixing bolt 15 is separated from the protective plate 2 and the main body 1, making it easy to replace the cleaning sticker 16. When installing the baffle 13, one side of the baffle 13 is engaged with one side of the protective plate 2, and the fixing bolt 15 is used to install the baffle 13 on the protective plate 2 and the main body 1, so that the cleaning sticker 16 can be used to clean the surface of the perforated plate 12.

[0038] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
