[0002] The existing flue gas particle concentration monitor needs to be installed on the wall to monitor the particles in the floating flue gas. Before installing the flue gas particle concentration monitor, it is necessary to punch holes in the wall first, and then set a bracket on the back of the instrument, and connect it to the hole with bolts to fix it. After multiple disassembly and assembly operations, the bolts will cause wear to the holes used for wall connection, affecting the stability of the installation of the flue gas particle concentration monitor, which is very inconvenient. Utility Model Content

[0003] Based on the above description, the utility model provides a flue gas particle concentration monitor to solve the problem that the existing flue gas particle concentration monitor will cause wear on the holes used for wall connection after multiple disassembly and assembly operations through bolts, thereby affecting the installation stability.

[0005] On the basis of the above technical solution, the present invention can also be improved as follows.

[0006] Furthermore, the positioning partition is in the shape of an isosceles trapezoid, and a side of the positioning partition away from the monitor is provided with rectangularly distributed assembly holes, and two sides of the inner wall of the positioning partition away from each other are provided with openings, which are distributed in a rectangular shape and are located outside the assembly holes.

[0007] Furthermore, the tensioning structure is composed of a sleeve plate and a tensioning belt. The sleeve plate is installed on the side of the positioning partition away from the monitor, and is arranged on the outside of the assembly hole in a circular shape with the center of the assembly hole as the center. The sleeve plate is annular, and the center of the circle coincides with the center of the assembly hole.

[0008] Furthermore, one end of the sleeve plate away from the monitor extends obliquely to the inner side of the assembly hole and is parallel to each other. The outer side of the sleeve plate is provided with anti-slip grooves, and the tensioning belt is installed between the ends of the sleeve plates that are close to each other and away from the monitor.

[0009] Furthermore, a gasket is installed on the side of the positioning partition away from the monitor, the gasket is annular and is located outside the sleeve, and the center of the gasket coincides with the center of the assembly hole.

[0010] Furthermore, the threaded rod is installed in a rectangular shape on one side of the monitor close to the positioning partition, and passes through the assembly hole to extend to the inner side of the sleeve plate, and the center of the threaded rod overlaps with the center of the assembly hole.

[0011] Furthermore, the positioning member is composed of a positioning pin, which is conical and spirally arranged on the outside. The positioning pin is installed on the outside of the threaded rod, and the end with a smaller diameter extends to the inside of the sleeve plate.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0013] The utility model uses a sleeve plate and a tensioning belt, in conjunction with a threaded rod and a locating pin. The sleeve plate is connected by the tensioning belt and is cylindrical in a normal state. The plugging operation with the hole in the wall is not affected. When the monitor is installed through the sleeve plate and the hole, the depth of the locating pin inserted into the inner side of the sleeve plate can be rotated and adjusted. The sleeve plate is affected by the cone shape of the locating pin and expands to different degrees until it fits and clamps with the inner wall of the hole in the wall to form a fixation. The operation is simple during the process, no props are required to assist, and no wear is caused to the hole, thereby ensuring the service life of the hole and the stability of subsequent installation and use of the equipment.

[0020] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0022] See also Figure 1-4 The utility model discloses a flue gas particulate matter concentration monitor, comprising a monitor 1, a positioning baffle 2 is installed on the surface of the monitor 1, a tensioning structure is arranged on the outer side of the positioning baffle 2, a threaded rod 6 extending to the inner side of the tensioning structure is installed on the surface of the monitor 1, a conical positioning piece is installed on the outer side of the threaded rod 6, the positioning piece moves horizontally along the outer side of the threaded rod 6 by rotation, and expands and reinforces the tensioning structure to different sizes.

[0023] See also Figure 1 The positioning partition 2 is in an isosceles trapezoidal shape. A rectangular assembly hole 21 is provided on the side of the positioning partition 2 away from the monitor 1. Openings 22 are provided on the two sides of the inner wall of the positioning partition 2 away from each other. The openings 22 are in a rectangular shape and are located on the outside of the assembly hole 21. The setting of the openings 22 allows the staff to reach into the inside of the positioning partition 2 from the side and rotate and adjust the positioning pin 7 on the outside of the threaded rod 6.

[0024] See also Figure 2 The tensioning structure is composed of a sleeve plate 3 and a tensioning belt 4. The sleeve plate 3 is installed on the side of the positioning partition plate 2 away from the monitor 1, and is arranged on the outside of the assembly hole 21 in a circular shape with the center of the assembly hole 21 as the center. The sleeve plate 3 is annular, and the center of the circle coincides with the center of the assembly hole 21. The end of the sleeve plate 3 away from the monitor 1 extends obliquely to the inner side of the assembly hole 21 and is parallel to each other. The outer side of the sleeve plate 3 is provided with anti-slip grooves 31. The anti-slip grooves 31 can increase the friction between the outer side of the sleeve plate 3 and the inner wall of the wall hole when it fits, and enhance the stability of the sleeve plate 3 after expansion and clamping. The tensioning belt 4 is installed between the sleeve plates 3 that are close to each other and away from the end of the monitor 1. The tensioning belt 4 can have a gathering effect on the sleeve plate 3 outside the assembly hole 21. When the sleeve plate 3 is expanded and used, the tensioning belt 4 can gather the sleeve plate 3 into a cylindrical shape, which is convenient for the sleeve plate 3 outside the assembly hole 21 to be inserted into the wall hole next time.

[0025] See also Figure 1A gasket 5 is installed on the side of the positioning partition 2 away from the monitor 1. The gasket 5 is annular and located on the outside of the sleeve 3. The center of the gasket 5 coincides with the center of the assembly hole 21. The sleeve 3 is arranged at an angle. The ends of the sleeves 3 that are close to each other need to be inserted into the hole in the wall. The ends of the sleeves 3 that are away from each other will protrude outside the hole due to their larger area. When the monitor 1 is installed, the gasket 5 will advance the end of the sleeve 3 that is away from each other to contact the wall, so as to avoid conflict between the end of the sleeve 3 that is away from each other and the hole in the wall, thereby ensuring the stability of the installation of the monitor 1.

[0026] See also Figure 4 The threaded rod 6 is rectangular and is installed on one side of the monitor 1 close to the positioning partition plate 2, and extends through the assembly hole 21 to the inner side of the sleeve plate 3. The center of the threaded rod 6 overlaps with the center of the assembly hole 21. The positioning piece is composed of a positioning pin 7. The positioning pin 7 is conical and spirally arranged on the outside. The positioning pin 7 is installed on the outside of the threaded rod 6, and the end with a smaller diameter extends to the inner side of the sleeve plate 3. When the sleeve plate 3 on the outside of the assembly hole 21 is inserted into the inner side of the wall hole, the positioning pin 7 can be rotated to adjust the depth of the positioning pin 7 inserted into the inner side of the sleeve plate 3. The conical setting of the positioning pin 7 allows the positioning pin 7 to be inserted into the inner side of the sleeve plate 3 and squeezed. The sleeve plate 3 can gradually expand until the sleeve plate 3 fits the inner wall of the hole to form a clamping, thereby fixing the monitor 1. Under the influence of the spiral setting on the outside of the positioning pin 7, the control of the expansion size of the sleeve plate 3 is more accurate, which increases the adaptability of the sleeve plate 3 to the inner wall of the hole. This fixing method will not cause wear to the wall hole, thereby ensuring the service life of the wall hole.

[0027] When the monitor 1 needs to be fixed, first align the assembly hole 21 with the hole in the wall, then insert the sleeve 3 outside the assembly hole 21 into the hole in the wall until the gasket 5 fits with the wall. Then the staff extends their hand along the opening 22 to the inside of the positioning partition 2 to control the positioning pin 7 to rotate on the outside of the threaded rod 6. The conical positioning pin 7 moves from small to large toward the inside of the sleeve 3 until the positioning pin 7 squeezes the sleeve 3, so that the sleeve 3 expands and fits the inner wall of the hole in the wall to fix the monitor 1.
