Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment technology, and in particular to an auxiliary support device for a flue gas monitor. Background Technology

[0002] Boilers, heating furnaces, and other furnace equipment generate large amounts of flue gas during operation, which contains pollutants such as sulfur dioxide, nitrogen oxides, carbon monoxide, and particulate matter. Existing flue gas monitoring instruments typically take samples by inserting a probe into the chimney, and rely on fixed devices or manual methods to maintain the probe in the sampling position.

[0003] However, in actual use, these monitoring instruments often need to operate continuously for several hours to obtain stable and complete data. Due to the lack of a reasonable fixing structure, traditional fixing structures usually only insert strips of cloth or other materials to secure the monitor at the flue gas monitoring port. However, because the flue gas monitor is too long, fixing only one end can cause the monitor to shift, leading to it falling or malfunctioning. In some fields, workers still rely on handheld or temporary supports to hold the probe at the flue gas monitoring port, which not only increases the workload but may also cause the monitoring data to be unstable due to human vibration. At the same time, prolonged manual support poses safety hazards, especially in high-temperature, high-altitude, or toxic gas environments, which can easily cause personnel fatigue or even accidents. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of existing flue gas monitors, which require manual support for fixation. This is problematic because prolonged manual support during monitoring can lead to fatigue and inaccurate data. Furthermore, traditional fixing structures typically only insert strips of cloth or similar materials at the flue gas monitoring port for fixation. However, due to the long length of the flue gas monitor, fixing only one end can cause the monitor to shift, potentially leading to it falling or malfunctioning. Therefore, this utility model provides an auxiliary support device for flue gas monitors.

[0005] In a first aspect, the present invention provides an auxiliary support device for a flue gas monitor, including a support ring structure, the support ring structure being connected to a flue gas monitoring port device, a flue gas monitor being connected to the middle of the support ring structure, a support rod being provided below the flue gas monitor, the support rod being arranged parallel to the flue gas monitor, and one end of the support rod being connected to the support ring structure; The support rod has a bracket at one end facing the flue gas monitor, and the bracket is used to mount the flue gas monitor.

[0006] This utility model provides an auxiliary support device for a flue gas monitor. By setting a support ring structure at the flue gas monitoring port and connecting the flue gas monitor through the support ring structure, the monitor can be stably positioned at the sampling location, avoiding the labor intensity and safety risks caused by prolonged manual handling. Furthermore, a support rod arranged parallel to the monitor is located below the support ring structure, and a bracket is provided at the end of the support rod to support the monitor. This not only improves the load-bearing stability of the monitor but also effectively reduces the stress on the support ring, preventing displacement or tilting of the monitor during long-term operation, thereby ensuring the continuity of the sampling process and the accuracy of the data. The device has a simple overall structure, is easy to install, and improves the safety and reliability of flue gas monitoring operations. Compared to fixing the flue gas monitor with cloth strips, this application uses a multi-point fixing method, which improves the stability of the flue gas monitor.

[0007] Preferably, the support ring structure includes a support ring that is snapped into the flue gas monitoring port device. The support ring has a first through hole, the size of which is adapted to the size of the flue gas monitor. The support ring also has a second through hole, the size of which is adapted to the size of the support rod.

[0008] By setting a first through hole on the support ring that matches the size of the flue gas monitor, the monitor can be reliably snapped into the support ring structure, ensuring the installation stability of the monitor; at the same time, a second through hole on the support ring that matches the size of the support rod allows the support rod to be firmly connected to the support ring, thereby further enhancing the overall support effect.

[0009] Preferably, the support ring structure further includes a sealing plate, the sealing plate including a sealing flange, and the sealing flange being connected to the flue gas monitoring port device; The sealing flange has a sealing element in the middle, and the sealing element has a third through hole for connecting the flue gas monitor. The sealing element also has a fourth through hole for connecting the support rod.

[0010] By incorporating a sealing plate within the support ring structure and connecting it to a sealing flange on the sealing plate for connection with the flue gas monitoring port device, the sealing performance of the flue gas monitoring port device can be ensured during installation, preventing flue gas leakage and improving the safety of the working environment. Furthermore, the sealing element is equipped with third and fourth through holes adapted to the flue gas monitoring instrument and the support rod, respectively, allowing for reliable installation of the monitoring instrument and the support rod in a sealed state, thus achieving a combination of support and sealing functions.

[0011] Preferably, the outer wall of the sealing flange is provided with a snap fastener, which is used to connect the sealing flange to the flue gas monitoring port device.

[0012] By setting snaps around the outer wall of the sealing flange, the sealing flange can be easily and quickly snapped into connection with the flue gas monitoring port device.

[0013] The flue gas monitoring port device in this application is a flange structure.

[0014] Preferably, the buckle includes an extension arm, one end of which is connected to the sealing flange and the other end is rotatably connected to a clamping plate. When the sealing flange needs to be installed, the clamping plate is moved so that the flue gas monitoring port device comes into contact with the sealing flange surface. Then the clamping plate is moved again so that the clamping plate comes into contact with the side of the flue gas monitoring port device away from the sealing flange. By setting a number of buckles circumferentially on the sealing flange, the movement of the sealing flange can be constrained by the clamping plate after it is moved, thereby realizing the connection between the sealing flange and the flue gas monitoring port device.

[0015] Preferably, the strut includes a support rod, one end of which passes through the fourth through hole and connects to the second through hole; The bracket is slidably connected to the other end of the support rod.

[0016] By sequentially passing the support rod through the fourth and second through holes, multi-point limiting and fixing of the support rod to the seal and support ring are achieved, thereby enhancing the stability of the support rod during use and avoiding loosening or displacement caused by single-point connection. Furthermore, the other end of the support rod is slidably connected to the bracket, allowing the bracket position to be adjusted according to the length of the flue gas monitor, increasing versatility.

[0017] Preferably, the bracket includes a bracket groove, the opening of which is oriented toward the support rod, and a pulley is provided in the bracket groove toward the support rod.

[0018] By providing a bracket groove on the bracket with the groove opening towards the support rod, the insertion and positioning of the support rod can be facilitated, simplifying the installation process. Furthermore, by installing pulleys in the bracket groove facing the support rod, a sliding connection is formed between the support rod and the bracket. This not only reduces the stress on the support rod but also facilitates adjustment of the bracket along the support rod's direction, thereby enabling adjustment of the flue gas monitor's installation position.

[0019] Preferably, the bracket groove has a snap-fit ​​groove on the side away from the support rod, and the snap-fit ​​groove is used to snap the flue gas monitor.

[0020] By setting a snap-fit ​​groove on the side of the bracket slot away from the support rod, the flue gas monitor can be quickly installed and securely fixed to the bracket through a snap-fit ​​method. At the same time, the snap-fit ​​structure facilitates disassembly and replacement in the later stage, improves maintenance efficiency, ensures the positional stability and reliability of the flue gas monitor during the detection process, and thus improves the accuracy of the monitoring results.

[0021] Preferably, the support ring body is a rubber structural component.

[0022] Preferably, the side of the snap-fit ​​groove facing the flue gas monitor has a flexible layer.

[0023] By setting a flexible layer on the side of the snap-fit ​​groove facing the flue gas monitor, the monitor can be buffered and protected during snap-fit ​​fixing, avoiding wear or damage to the monitor surface due to hard contact.

[0024] Preferably, the flue gas monitor includes a monitoring rod, one end of which is connected to the support ring structure and the other end is connected to a monitoring head.

[0025] Preferably, the flue gas monitor is equipped with a temperature sensor at one end of the flue gas monitoring port device.

[0026] By installing a temperature sensor at one end of the flue gas monitoring port of the flue gas monitor, the flue gas temperature at the monitoring port can be monitored in real time, providing a basis for the correction and comprehensive analysis of monitoring data such as flue gas concentration and flow rate, thereby improving the accuracy of monitoring results.

[0027] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model provides an auxiliary support device for a flue gas monitor. By setting a support ring structure at the flue gas monitoring port and securing the flue gas monitor to the device via the support ring structure, the monitor can be stably positioned at the sampling location, avoiding the labor intensity and safety risks associated with prolonged manual handling. Furthermore, a support rod located below the support ring structure is arranged parallel to the monitor, and a bracket is provided at the end of the support rod to support the monitor. This not only improves the load-bearing stability of the monitor but also effectively reduces the stress on the support ring, preventing displacement or tilting of the monitor during prolonged operation, thereby ensuring the continuity of the sampling process and the accuracy of the data. The device has a simple overall structure, is easy to install, and can improve the safety and reliability of flue gas monitoring operations. Attached Figure Description

[0036] Example 1 like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The auxiliary support device for a flue gas monitor shown includes a support ring structure 1, which is located inside the flue gas monitoring port device and is snapped into the flue gas monitoring port device. The flue gas monitor 2 is snapped into the support ring structure 1. A support rod 3 is also snapped into the lower part of the support ring structure 1. The support rod 3 is located below the flue gas monitor 2 and is arranged parallel to the flue gas monitor 2. A bracket 31 is provided on the side of the support rod 3 facing the flue gas monitor 2. The bracket 31 is used to support the flue gas monitor 2. Specifically, one end of the flue gas monitor 2 is snapped into the support ring structure 1 and the other end is fixed by the bracket 31 to ensure that the flue gas monitor 2 is in a horizontal position. Furthermore, the support ring structure 1 includes a support ring 11 located inside the flue gas monitoring port device. The support ring 11 has a first through hole 111, the size of which is adapted to the size of the flue gas monitor 2, so that the monitoring end of the flue gas monitor 2 can be inserted into the chimney through the first through hole 111 to absorb the flue gas. The support ring 11 also has a second through hole 112, the size of which is adapted to the size of the support rod 3, so that one end of the support rod 3 can be engaged in the second through hole 112, ensuring the stability of the support rod 3 when supporting the flue gas monitor 2 in the future. Furthermore, the support ring structure 1 also includes a sealing flange 121, which is connected to the flue gas monitoring port device. The sealing flange 121 has a sealing element 122 in the middle. The sealing element 122 has a third through hole 1221 for the flue gas monitor 2 to pass through, and a fourth through hole 1222 for the support rod 3 to pass through. The flue gas monitor 2 is fixed by the support ring 11 and the first through hole 111 and the third through hole 1221 on the sealing element 122, which improves the stability of the flue gas monitor 2. The support rod 3 is fixed by the support ring 11 and the second through hole 112 and the fourth through hole 1222 on the sealing element 122, which improves the stability of the support rod 3 and facilitates the subsequent support of the flue gas monitor 2 by the support rod 3.

By providing the snap fastener 1211 on the outer wall of the sealing flange 121, the sealing flange 121 can be easily and quickly snapped into connection with the flue gas monitoring port device. Figure 2 and Figure 4 As shown; Optionally, the buckle 1211 includes an extension arm, one end of which is fixedly connected to the side of the sealing flange 121 facing the flue gas monitoring port device, and the other end of which is rotatably connected to a clamping plate. The clamping plate can rotate around the extension arm. During installation, the sealing flange 121 is first placed against the end of the flue gas monitoring port device, so that the sealing flange 121 and the flue gas monitoring port device form surface-to-face contact; then the clamping plate is moved to rotate around the extension arm, so that one end of the clamping plate abuts against the surface of the flue gas monitoring port device away from the sealing flange 121. With this structure, when multiple clamping plates are all moved into place, multiple limiting points are formed around the flue gas monitoring port device, which can effectively prevent the sealing flange 121 from detaching or shifting relative to the flue gas monitoring port device.

[0039] In one or more embodiments, the bracket 31 includes a bracket groove 311, the opening of which faces the support rod 32. A pulley 3111 is provided in the bracket groove 311 facing the support rod 32. By providing the bracket groove 311 on the bracket 31 and having its opening facing the support rod 32, the support rod 32 can be easily inserted and positioned, simplifying the installation process. Furthermore, the pulley 3111 in the bracket groove 311 facing the support rod 32 creates a sliding connection between the support rod 32 and the bracket 31. This not only reduces the stress on the support rod 32 but also facilitates adjustment of the bracket 31 along the support rod 32, thereby enabling adjustment of the installation position of the flue gas monitor 2. Furthermore, the bracket groove 311 has a snap-fit ​​groove 312 on the side away from the support rod 32. The snap-fit ​​groove 312 is used to snap the flue gas monitor 2. By providing the snap-fit ​​groove 312 on the side of the bracket groove 311 away from the support rod 32, the flue gas monitor 2 can be quickly installed and securely fixed to the bracket 31 through a snap-fit ​​method. At the same time, the snap-fit ​​structure facilitates disassembly and replacement in the later stage, improves maintenance efficiency, and ensures the positional stability and reliability of the flue gas monitor 2 during the detection process, thereby improving the accuracy of the monitoring results. Figure 5 As shown; Furthermore, the support ring 11 body is a rubber structural component, and the side of the snap-fit ​​groove 312 facing the flue gas monitor 2 is provided with a flexible layer.

[0040] In one or more embodiments, the flue gas monitor 2 is provided with a temperature sensor at one end facing the flue gas monitoring port device. By setting a temperature sensor at one end of the flue gas monitor 2 at the flue gas monitoring port device, the flue gas temperature at the flue gas monitoring port device can be monitored in real time, providing a basis for the correction and comprehensive analysis of monitoring data such as flue gas concentration and flow rate, thereby improving the accuracy of monitoring results.

In this embodiment, the support rod 32 is configured as a single unit, and the entire bracket 31 is cylindrical to allow the support rod 32 to pass through. A through hole communicating with the support groove is provided on the side wall of the bracket 31, and a limiting screw 5 is also provided in the through hole.
