[0020] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention. Example

[0021] like Figures 1 to 3 As shown, where Figure 1 This is a schematic diagram of the overall structure of the flue gas emission monitoring device. Figure 2 This is a schematic diagram showing the installation position of sealing gasket 104. Figure 3This is a cross-sectional view of the mounting base 103. This utility model provides a flue gas emission monitoring device, including a flue gas duct 101, a monitoring component 102, and an installation component. The installation component includes a mounting base 103, a sealing gasket 104, a monitoring probe body 105, a hexagonal block 106, a connecting cable 107, a filter component, and a wiring component. The filter component includes a connecting pipe 108 and a filter pipe 109. The wiring component includes a wiring pipe 110 and a fixing component. The fixing component includes a positioning plate 111 and a connecting rod 112. The aforementioned solution solves the problem of cumbersome operation during the installation or removal of the monitoring probe body 105 in existing monitoring devices, resulting in long installation or removal times and inconvenience. It is understood that the aforementioned solution allows for faster installation or removal of the monitoring probe body 105, making it more convenient to use.

[0022] In this embodiment, the monitoring component 102 is installed on the flue gas duct 101. The monitoring component 102 can directly adopt the monitoring module structure disclosed in the prior art CN221238829U. Since its working principle and internal structure are already existing technologies, they will not be described in detail here.

[0023] The mounting base 103 is detachably connected to the flue gas duct 101 and is located at the monitoring port of the flue gas duct 101. The sealing gasket 104 is detachably connected to the mounting base 103 and is disposed on the end face of the mounting base 103 away from the flue gas duct 101. The monitoring probe body 105 is threadedly connected to the mounting base 103 and abuts against the sealing gasket 104. The hexagonal block 106 is integrally formed with the housing of the monitoring probe body 105 and is located on the housing of the monitoring probe body 105 away from the mounting base 103. The connecting cable 107 is electrically connected to the monitoring probe body 105 and the monitoring component 102 respectively. The filter component is detachably disposed on the end of the mounting base 103 away from the monitoring probe body 105. The wiring component is disposed on the left side of the monitoring component 102 and is detachably connected to the connecting cable 107. The mounting base 103 has a U-shaped cross-section. After its front circular portion slides into the monitoring port on the flue gas duct 101, the disc is fixed by bolts. The bolt holes do not penetrate the flue gas duct 101. Both sides of the internal cavity of the mounting base 103 are threaded cavities, which facilitates the installation of the filter component and the monitoring probe body 105. The housing of the monitoring probe body 105 is provided with an external threaded mounting end and a hexagonal block 106. The mounting base 103 is provided with a mounting groove, which facilitates the embedding and installation of the sealing gasket 104. The sealing gasket 104 is made of high-temperature resistant rubber and is used to seal the contact surface between the monitoring probe body 105 and the mounting base 103 after the monitoring probe body 105 is installed. The monitoring probe body 105 is connected to the monitoring component 102 through the connecting cable 107. The filter component is used to filter the flue gas and reduce impurities on the collection part of the monitoring probe body 105. The cable routing component is used to assist in setting the connecting cable 107.

[0024] Secondly, the connecting pipe 108 is threadedly connected to the fixing base 103 and is located on the side of the fixing base 103 away from the monitoring probe body 105; the filter pipe 109 is integrally formed with the connecting pipe 108 and has several filter holes arranged in a ring at intervals, and the collection part of the monitoring probe body 105 extends into the filter pipe 109. The external thread end on the connecting pipe 108 can be directly installed in the threaded cavity on the side of the fixing base 103 away from the monitoring probe body 105. The filter pipe 109 is used for flue gas filtration to reduce impurities on the collection part of the monitoring probe body 105. When cleaning the filter pipe 109 regularly, simply remove the fixing bolts of the fixing base 103, then remove the fixing base 103, and then remove the connecting pipe 108 for cleaning. The monitoring probe body 105 does not need to be disassembled during cleaning.

[0025] Then, the cable conduit 110 is sleeved on the outside of the connecting cable 107 and vertically positioned on the left side of the monitoring component 102; the fixing component is located on the monitoring component 102 near the cable conduit 110. The cable conduit 110 can be directly sleeved on the outside of the connecting cable 107, and the fixing component is used to fix the cable conduit 110.

[0026] Finally, the positioning disk 111 is connected to the housing of the monitoring component 102, and two are vertically arranged; the connecting rod 112 is welded and fixed to the positioning disk 111 and the cable tray 110 respectively. The positioning disk 111 is fixed by bolts, and the two ends of the connecting rod 112 are welded and fixed to the positioning disk 111 and the cable tray 110 respectively, thereby ensuring good stability. The length of the connecting cable 107 between the monitoring probe body 105 and the top inlet of the cable tray 110 is set so that the cable will not break when the fixing seat 103 is removed after the fixing bolts of the fixing seat 103 are loosened.

[0027] To address the problem of cumbersome installation and disassembly of existing monitoring devices, which result in lengthy installation and disassembly times and inconvenience, this invention directly mounts the monitoring component 102 onto the flue gas duct 101 and electrically connects it to the monitoring probe body 105 via the connecting cable 107, thus forming a monitoring structure. During monitoring, the monitoring probe body 105 contacts the flue gas and collects data. The data is then fed back to the monitoring component 102 for processing to complete the monitoring. Furthermore, the solid... The mounting base 103 is provided with a threaded cavity, which facilitates direct installation of the external threaded end on the housing of the monitoring probe body 105. The housing of the monitoring probe body 105 is integrally provided with the hexagonal block 106, which can be directly installed or removed by rotating it with a wrench. Compared with the existing technology that uses multiple sets of latches and buckles for fixing, the monitoring probe body 105 will be easier to operate quickly during installation and removal. This solves the problem that the existing monitoring devices are cumbersome to operate during the installation or removal of the monitoring probe body 105, resulting in long installation or removal time and inconvenience.

[0028] Example 2:

[0029] like Figure 4 and Figure 5 As shown, where Figure 4 This is a schematic diagram of the overall structure of the flue gas emission monitoring device. Figure 5This is a schematic diagram of the structure of the threaded rubber plug 201. Based on the first embodiment, this utility model provides a flue gas emission monitoring device. The cable assembly also includes a threaded rubber plug 201. The threaded rubber plug 201 is threadedly connected to the cable conduit 110 and slidably connected to the connecting cable 107, and is located at the inlet and outlet of the cable conduit 110, respectively. The threaded rubber plug 201 has a T-shaped cross-section and is made of rubber with a certain elastic hardness, which is beneficial for having a certain elastic deformation buffering capacity. The internal circular cavity is set according to the outer diameter of the connecting cable 107, which facilitates the pulling and passing of the connecting cable 107. The inlet and outlet of the cable conduit 110 are both set as threaded cavities, which facilitates the installation of the threaded rubber plug 201.

[0030] In this embodiment, by installing the threaded rubber plugs 201 at the inlet and outlet of the cable conduit 110, the edges of the inlet and outlet of the cable conduit 110 can be prevented from scratching the outer sheath of the cable when the connecting cable 107 is pulled, thereby improving the working safety of the connecting cable 107.
