Abstract
Description
Technical Field
[0001] This utility model relates to the field of probe protection technology, and in particular to a probe protection device. Background Technology
[0002] In the metallurgical field, probe protection devices play a crucial role. Because metallurgical equipment operates in environments involving high temperatures, high pressures, dust, and potential chemical corrosion, probe protection devices must not only protect the probes from physical damage but also ensure their accuracy and reliability. This is especially true for probes used for continuous monitoring of flame combustion within boiler furnaces, where their stability and durability directly impact the safe and stable operation of the boiler. Traditional probe protection devices have limitations in design and function. For example, many devices cannot be length-adjusted to accommodate different furnace dimensions, resulting in ineffective coverage of the entire monitoring area in practical applications. Furthermore, the protective effect of these devices during and after use is often unsatisfactory. During use, the probe may suffer impacts or wear due to the complex environment within the furnace; after use, due to the lack of effective protection mechanisms, the probe may be damaged by accidental collisions or improper storage. Therefore, a probe protection device is needed. Utility Model Content

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0024] Example 1:
[0025] like Figure 1 and Figure 6 As shown, a probe protection device includes a telescopic mechanism 2. Support components 1 are symmetrically and fixedly connected to the upper part of the outer surface of the telescopic mechanism 2 away from its axis. A turntable 5 is rotatably connected to the upper end of the support component 1. A turntable 6 is rotatably connected to the inner cavity of the turntable 5. A protective mechanism 3 is fixedly connected to the lower end of the telescopic mechanism 2. A probe head 4 is fixedly connected to the inner cavity of the protective mechanism 3.
[0026] The probe head 4 described above is covered with a protective shell made of quartz glass for heat insulation, which can effectively block heat transfer, protect the internal electronic components of the probe from high temperature damage, and effectively reduce the risk of performance degradation or failure due to overheating. This utility model will not be described in detail here.
[0027] In use, first open the furnace cover to be detected, then adjust the length of the support assembly 1 according to the size of the furnace body, and then place the two sides of the support assembly 1 on the upper edge of the furnace body. Then, rotate the turntable 5 according to the size of the furnace body to drive the internal structure of the telescopic mechanism 2 to rotate. Under the action of the internal structure of the telescopic mechanism 2, the protective mechanism 3 is driven to descend into the furnace body. Then, the protective mechanism 3 drives the probe head 4 to descend into the furnace body. Then, rotate the turntable 6 to drive the internal structure of the protective mechanism 3 to rotate. The operation of the internal structure of the protective mechanism 3 makes the surface of the probe head 4 exposed, so that it can monitor the flame combustion in the furnace. The internal structure of the protective mechanism 3 can effectively resist and buffer the splashing slag, falling materials or other mechanical parts impacted by the furnace, and can provide a solid barrier when the probe is working. After use, remove the entire device from the furnace body, and then rotate the turntable 6 again to make the internal structure of the protective mechanism 3 retract to provide a safe storage environment for the probe head 4.
[0028] Example 2:
[0029] In order to achieve the goal of adjusting the height of probe head 4 according to different furnace body sizes, refer to Figure 2 and Figure 3 In this scheme, the support component 1 includes two support blocks 11. The two support blocks 11 are respectively fixedly connected to the upper part of the outer surface of the telescopic mechanism 2 away from its axis. The lower end of each of the two support blocks 11 is provided with a sliding groove 14. The inner cavity of each of the two sliding grooves 14 is slidably connected with a slider 12. The lower end of each of the two sliders 12 is fixedly connected with a locking block 13.
[0030] When in use, first open the boiler cover, then slide the slider 12 in the inner cavity of the groove 14 according to the diameter of the furnace body, and then drive the two locking blocks 13 to symmetrically lock into the edge of the furnace body through the two sliders 12, so that the entire device is fixed above the furnace body.
[0031] Furthermore, the telescopic mechanism 2 includes a support tube 21, which is fixedly connected to one end of two support blocks 11 that are close to each other. A threaded rod 23 is rotatably connected to the upper wall of the inner cavity of the support tube 21. A round tube 22 is threadedly connected to the outer surface of the threaded rod 23. A rotating rod 24 is rotatably connected to the inner cavity of the threaded rod 23.
[0032] The upper end of the threaded rod 23 extends through the upper wall of the support tube 21 to the outside and is fixedly connected to the lower end of the turntable 5. The upper end of the rotating rod 24 extends through the upper wall of the inner cavity of the threaded rod 23 to the outside and is fixedly connected to the lower end of the turntable 6.
[0033] When it is necessary to extend the probe 4 into the furnace body to a suitable height, the rotating turntable 5 drives the threaded rod 23 to rotate. As the threaded rod 23 rotates, it drives the threaded tube 22 on the outer surface to slide downward. Then, the tube 22 descends, driving the lower protective mechanism 3 to move downward, thereby achieving the purpose of lowering the probe 4 to a suitable height in the furnace body.
[0034] Example 3:
[0035] The only difference between this embodiment and embodiment 1 or 2 is that, as referenced... Figure 4 In this scheme, the protective mechanism 3 includes a fixed disk 31 and a rotating disk 35. The fixed disk 31 is fixedly connected to the lower end of the circular tube 22. The lower end of the fixed disk 31 has a plurality of T-shaped grooves 32 arranged in an annular array. T-shaped blocks 33 are slidably connected to the inner cavities of the plurality of T-shaped grooves 32. The ends of the plurality of T-shaped blocks 33 away from the axis of the fixed disk 31 on the same side extend through the inner wall of the T-shaped groove 32 on the same side to the outside. A protective plate 37 is fixedly connected to the side of the plurality of T-shaped blocks 33 away from the axis of the fixed disk 31 on the same side. The rotating disk 35 is fixedly connected to the lower end of the rotating rod 24. The outer surface of the rotating disk 35 has a plurality of arc-shaped grooves 36 arranged in an annular array. A sliding rod 34 is fixedly connected to the side of the lower end of the plurality of T-shaped blocks 33 near the axis of the fixed disk 31.
[0036] Furthermore, the lower ends of several of the slide rods 34 are slidably connected to the inner cavity of the arc-shaped groove 36 on the same side, and the ends of several of the guard plates 37 away from the axis of the fixed plate 31 are fixedly connected to a buffer assembly 38.
[0037] When the probe 4 reaches the appropriate height, the rotating turntable 6 drives the rotating rod 24 to rotate, which in turn drives the rotating disk 35 to rotate. As the rotating disk 35 rotates, it causes several arc-shaped grooves 36 on its surface to rotate around the axis of the rotating disk 35. This movement of the arc-shaped grooves 36 causes the sliding rod 34 to move away from the axis of the rotating disk 35 within the arc-shaped groove 36. This causes the sliding rod 34 to drive several T-shaped blocks 33 to slide outward within the T-shaped groove 32, which in turn causes several protective plates 37 to move outward around the axis of the fixed disk 31. This creates gaps between adjacent protective plates 37, allowing the probe 4 to monitor the combustion of the flame inside the furnace through these gaps. The several buffer components 38 effectively resist and buffer the molten slag splashing from inside the furnace, effectively protecting the probe 4.
[0038] Furthermore, in order to prevent the molten slag in the furnace from damaging the probe head 4, refer to Figure 5The buffer assembly 38 includes a plurality of fixed boxes 381, each fixedly connected to one end of the protective plate 37 away from the axis of the fixed disk 31. A plurality of spring pieces 382 are fixedly connected to the inner cavity of each of the fixed boxes 381, and an arc-shaped plate 383 is fixedly connected to the end of each spring piece 382 away from the axis of the fixed disk 31 on the same side. The arc-shaped plates 383 are slidably connected to the inner cavity of the fixed boxes 381 on the same side.
[0039] Thus, through the action of several protective plates 37, several fixed boxes 381 extend outward, and through the action of several spring pieces 382, the molten slag splashing inside the furnace can be effectively buffered when it impacts the surface of the arc plate 383, providing a solid barrier when the probe head 4 is working.
