[0029] The present application is further described below in detail through specific embodiments in conjunction with the accompanying drawings.

[0030] like Figure 1 and Figure 2As shown, a leakage monitoring probe with anti-wear, anti-corrosion and anti-ash deposition in a high-sulfur and high-ash flue gas environment comprises a monitoring probe body 1 and an assembly seat 2, wherein the assembly seat 2 can be detachably assembled in a reserved mounting hole of a ceiling, and is characterized in that a hanging pipe 3 is mounted on the upper end of the monitoring probe body 1, the upper end of the hanging pipe 3 extends upward and is plugged into the assembly seat 2, a limiting component 5 which can be elastically contracted toward the inside thereof is mounted on the upper end of the hanging pipe 3, a driving component 6 for driving the limiting component 5 to move is mounted inside the lower end of the hanging pipe 3, and the hanging pipe 3 is assembled with the assembly seat 2 by clamping through the limiting component 5;

[0031] like Figure 2 As shown, the limiting assembly 5 includes a turntable 51, a limiting plate 52, and a connecting rod 53. The turntable 51 is rotatably mounted on the upper end of the inner cavity of the hanging tube 3 and driven by the driving assembly 6. When the driving force of the driving assembly 6 is lost, the turntable 51 can be reversely rotated and reset. The limiting plate 52 is arranged on the outer wall of the upper end of the hanging tube 3. One end of the limiting plate 52 is clamped with the inner wall of the assembly seat 2. The other end of the limiting plate 52 slides and extends into the hanging tube 3 and is connected to the turntable 51 through the connecting rod 53. The two ends of the connecting rod 53 at the other end of the limiting plate 52 are respectively hinged to the turntable 51 and the limiting plate 52.

[0032] The assembly seat 2 includes an upper cover ring 21, a lower cover ring 22 and a connecting pipe 23. The upper cover ring 21 and the lower cover ring 22 are respectively installed at the upper and lower ends of the connecting pipe 23. The connecting pipe 23 is sleeved in the reserved hole of the ceiling. The upper cover ring 21 and the lower cover ring 22 are both made of deformable plastic materials. After the clamping assembly, they are restored to their original state, so that the upper cover ring 21 and the lower cover ring 22 are respectively clamped on the upper and lower end surfaces of the ceiling, thereby completing the stable assembly of the assembly seat 2 and the ceiling;

[0033] The inner wall of the upper cover ring 21 is provided with a limit groove 14 adapted to the limit plate 52. The limit plate 52 is plugged into the limit groove 14, so that the upper end of the hanging pipe 3 can be combined with the upper cover ring 21, thereby completing the hanging operation of the monitoring probe body 1;

[0034] It should be noted that the lower end surface of the upper cover ring 21, the upper end surface of the lower cover ring 22 and the outer peripheral surface of the connecting pipe 23 are all provided with sealing gaskets 15, and the sealing gaskets 15 are in close contact with the ceiling, which can improve the installation firmness and sealing of the assembly seat 2, and to a certain extent prevent the leaked smoke from escaping outward through the reserved holes.

[0035] During installation, the turntable 51 is driven to rotate by the driving component 6, and the two ends of the connecting rod 53 are respectively hinged to the turntable 51 and the limit plate 52, so that the turntable 51 drives one end of the connecting rod 53 to tilt, and the other end of the connecting rod 53 drives the limit plate 52 to slide and shrink to the inside of the hanging tube 3, and then through the connection between the upper end of the hanging tube 3 and the assembly seat 2, by loosening the driving component 6, the turntable 51 loses the driving force of the driving component 6 and rotates in the opposite direction and resets, thereby driving the connecting rod 53 to reset, and then driving the limit plate 52 to slide and extend to the outside of the hanging tube 3 again, and the limit plate 52 is snap-fitted and assembled with the assembly seat 2 to complete the quick assembly of the hanging tube 3 and the assembly seat 2, and then complete the hanging of the monitoring probe body 1, without the need for threaded rotation assembly, the actual operation is simple and convenient, avoiding the problem of wiring entanglement caused by rotation assembly, and bringing convenience to later inspection and maintenance work.

[0036] Specifically, Figure 3 As shown, there are multiple limit plates 52 and they are evenly distributed along the circumference of the outer wall of the hanging pipe 3. The number of connecting rods 53 is consistent with the number of limit plates 52 and corresponds one to one. The setting of multiple limit plates 52 can improve the assembly tightness and stability between the upper end of the hanging pipe 3 and the assembly seat 2.

[0037] Specifically, Figure 4 As shown, an inlet and outlet 8 adapted to the limit plate 52 is opened on the outer periphery of the upper end of the hoisting pipe 3, the limit plate 52 is arranged in the inlet and outlet 8, and the outer wall of the limit plate 52 is slidably connected to the inner wall of the inlet and outlet 8, so as to facilitate the horizontal extension and retraction of the limit plate 52;

[0038] Furthermore, if Figure 4 As shown, the inner wall of the upper end of the hoisting pipe 3 is installed with slide rails 7 located on both sides of the inlet and outlet 8, and the two sides of the limit plate 52 are respectively slidably connected to the adjacent slide rails 7, which can improve the stability of the horizontal extension and retraction of the limit plate 52.

[0039] Specifically, Figure 5 As shown, the driving assembly 6 includes a rotating column 61, a gear 62, a rack 63, a button 64, and a connecting plate 65. The rotating column 61 is rotatably mounted on the lower end of the inner cavity of the hanging tube 3, the turntable 51 is mounted on the upper end of the rotating column 61, the gear 62 is mounted on the lower end of the rotating column 61 and meshed with the rack 63, the button 64 is slidably sleeved on the outer periphery of the bottom end of the hanging tube 3, one end of the button 64 extends into the hanging tube 3 and is connected to one end of the rack 63 away from the rotating column 61 through the connecting plate 65, and the connecting plate 65 is reset by the rebound assembly;

[0040] A movable hole adapted to and corresponding to the button 64 is provided on the outer periphery of the lower end of the hanging pipe 3, and the button 64 is slidably sleeved in the movable hole, so that the button 64 can drive the connecting plate 65 and the rack 63 to move;

[0041] In the specific design, the number of limit plates 52 is four, the maximum rotation degree of the turntable 51 is ninety degrees, the outer circumference of the gear 62 has 12 teeth, and the maximum forward distance of the rack 63 is three teeth. When the rack 63 moves the maximum distance, the gear 62 rotates a quarter of a circle, that is, the gear 62 rotates ninety degrees, and the turntable 51 can be rotated ninety degrees to achieve normal telescopic adjustment of the four limit plates 52.

[0042] Furthermore, the number of the rebound components is two, and the two rebound components are symmetrically distributed on both sides of the button 64, which can improve the actual adjustment stability;

[0043] Further, the rebound assembly includes a fixed block 9, a fixed rod 10, and a spring 11. The number of the fixed blocks 9 is two and they are arranged opposite to each other. The fixed rod 10 and the rack 63 are parallel to each other, and the two ends of the fixed rod 10 are respectively fixedly connected to the two fixed blocks 9. The end of the connecting plate 65 is slidably mounted on the fixed rod 10. The spring 11 is mounted on the fixed rod 10, and the two ends of the spring 11 are respectively connected to the connecting plate 65 and the end surface of one of the fixed blocks 9.

[0044] When the button 64 drives the connecting plate 65 to move, the two ends of the connecting plate 65 slide horizontally along the fixing rod 10 and squeeze the spring 11. When the button 64 is released, the spring 11 returns to its original state and drives the connecting plate 65 and the button 64 to retreat and reset, so that the rack 63 drives the gear 62 to rotate in the opposite direction, and the rotating column 61 drives the rotating disk 51 to rotate in the opposite direction, thereby making the limiting plate 52 extend outward so that the limiting plate 52 is engaged with the assembly seat 2.

[0045] Furthermore, a stabilizing plate 12 is installed at one end of the connecting plate 65 away from the rack 63, and the stabilizing plate 12 and the rack 63 are symmetrically distributed on both sides of the gear 62. A cover plate 13 is installed on the side of the stabilizing plate 12 close to the gear 62. The cover plate 13 is pressed on the upper end surface of the gear 62 and there is a gap with the rotating column 61. The upper end surface of the gear 62 is slidably connected to the cover plate 13, which can improve the meshing transmission stability between the rack 63 and the gear 62.

[0046] Specifically, the shell of the monitoring probe body 1 is made of ceramic-based composite material or silicon carbide material, which can improve the wear and corrosion resistance, and the surface of the shell has a nano-level wear-resistant and corrosion-resistant coating, such as aluminum oxide or titanium dioxide coating, to further enhance the protection performance.

[0047] Specifically, a micro motor is installed inside the lower end of the monitoring probe body 1, and the output end of the micro motor extends downward to the outside of the monitoring probe body 1 and is installed with a cleaning brush 4. The bristle part of the cleaning brush 4 is in contact with the lower filter screen of the monitoring probe body 1. The cleaning brush 4 is driven by the micro motor to move circumferentially along the lower filter screen of the monitoring probe body 1, so that the lower filter screen can be cleaned regularly to prevent dust accumulation from affecting heat dissipation.

[0048] The technical features of the above embodiments may be arbitrarily combined (as long as there is no contradiction in the combination of these technical features). To make the description concise, not all possible combinations of the technical features in the above embodiments are described; these embodiments that are not explicitly written should also be considered to be within the scope of this specification.
