Description

Technical Field

[0001] This utility model is a wide-range flue gas temperature measuring device, belonging to the technical field of flue gas temperature measuring equipment. Background Technology

[0002] In the field of industrial process measurement, flue gas temperature measuring devices (such as thermocouples, resistance temperature detectors (RTDs), and their assembled temperature probes) are key monitoring components for equipment such as boilers, furnaces, and chemical reactors. Their performance and stability are directly related to production safety, energy efficiency control, and environmental emissions. The core sensing part of these measuring devices is usually located at the end of the probe. The structure is precise and fragile, especially some high-temperature protective sleeves made of ceramic materials, which have poor impact resistance. During transportation, storage, or waiting for installation, they are easily damaged by bumps, drops, or contact with dust and moisture, leading to inaccurate measurements or even complete scrapping.

[0003] Currently, common protective methods (such as wrapping with bubble wrap or covering with ordinary plastic caps) have problems such as weak protection, easy detachment, and inconvenience in disassembly and assembly. This often results in the probe being damaged before it is put into use, increasing user costs and maintenance workload. There is an urgent need for a wide-range flue gas temperature measurement device to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a wide-range flue gas temperature measurement device to solve the problems mentioned in the background. This utility model has a reasonable structure and good practicality. By setting up a quick-release protective component, it provides reliable terminal protection for the flue gas temperature probe in non-use states such as transportation and storage, effectively preventing the probe tip from being damaged by bumps during circulation, ensuring the accuracy and lifespan of the internal sensor. Its convenient feature of being able to be installed and disassembled by hand significantly improves operational efficiency.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a wide-range flue gas temperature measuring device, comprising a measuring device body, a protective sleeve, and a clamping rod. A probe is provided on the right side of the measuring device body, and a flange is fixedly sleeved on the outer side of the probe. Multiple equidistant grooves are provided on the outer circumference of the flange. A circular shell is fixed to the right end of the protective sleeve, and a circular rod is rotatably mounted on the left side of the circular shell. A protrusion is fixed to the right end of the circular rod. Multiple sets of circular hole blocks are fixed in a circumferential array on the annular side of the protective sleeve, and each set of circular hole blocks is linearly arranged. A first spring is fixed to the side of each of the circular hole blocks away from the protective sleeve. The clamping rod is L-shaped, and a notched circular rod is fixed to the lower right end of the clamping rod. A U-shaped plate is slidably sleeved on the outer side of the notched circular rod. A roller is rotatably mounted inside the notch at the lower end of the notched circular rod. A circular ring is fixedly sleeved on the lower outer end of the notched circular rod, and a second spring is fixed above the circular ring and sleeved on the outer side of the notched circular rod. The upper end of the second spring is fixed to the U-shaped plate.

[0006] Furthermore, a reset torsion spring is fixed to the left end of the protrusion block and sleeved on the outside of the round rod. The left end of the reset torsion spring is fixedly connected to the round shell, and an anti-slip knob is installed on the right end of the protrusion block.

[0007] Furthermore, multiple guide rods are fixed below the clamping rod, and the clamping rod is provided with multiple U-shaped plates that are circumferentially fixed at equal intervals to the right end of the inner wall of the circular shell.

[0008] Furthermore, the outer circumference of the circular shell is provided with multiple transition holes at equal intervals, and the multiple circular rods pass through the multiple transition holes respectively.

[0009] Furthermore, the multiple guide rods are slidably installed in the circular holes of the multiple circular hole blocks, and the ends of the multiple first springs away from the circular hole blocks are respectively fixed to the locking rods.

[0010] Furthermore, a sealing ring is fixed to the left end of the protective sleeve.

[0011] The beneficial effects of this utility model are as follows: This utility model provides a wide-range flue gas temperature measuring device. Because it incorporates a flange, protective sleeve, round shell, anti-slip knob, locking rod, protrusion block, round hole block, first spring, guide rod, notched round rod, U-shaped plate, ring, second spring, roller, round rod, and reset torsion spring, our design improvements and practical use have shown that this device has a reasonable structure and good practicality.

Detailed Implementation

[0014] 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.

[0015] Please see Figures 1-7 This utility model provides a technical solution: a wide-range flue gas temperature measuring device, including a measuring device body 1, a protective sleeve 4, and a locking rod 8. A probe 2 is provided on the right side of the measuring device body 1, and a flange 3 is fixedly sleeved on the outside of the probe 2. Multiple locking grooves 7 are equidistantly arranged on the outer circumference of the flange 3. A circular shell 5 is fixed to the right end of the protective sleeve 4, and a circular rod 19 is rotatably mounted on the left side of the circular shell 5. A protrusion 10 is fixed to the right end of the circular rod 19. Multiple sets of circular hole blocks 11 are fixed in a circumferential array on the annular side of the protective sleeve 4, and each set of circular hole blocks 11 is linearly arranged. A first spring 12 is fixed to the side of each of the multiple circular hole blocks 11 away from the protective sleeve 4. The locking rod 8 is L-shaped, and a notched circular rod 14 is fixed to the lower right end of the locking rod 8. A U-shaped plate 15 is slidably sleeved on the outside of the notched circular rod 14. A roller 18 is rotatably installed in the notch at the lower end of the notched circular rod 14. A ring 16 is fixedly sleeved on the lower outside of the notched circular rod 14. A second spring 17 is fixed above the ring 16 and sleeved on the outside of the notched circular rod 14. The upper end of the second spring 17 is fixed to the U-shaped plate 15. This design solves the problems of the existing probe protection methods, such as weak protection, easy detachment, and inconvenient disassembly and assembly, which often result in the probe being damaged before it is put into use, increasing user costs and maintenance workload.

[0016] As the first embodiment of this utility model: a reset torsion spring 20 is fixed to the left end of the protrusion 10 and sleeved on the outside of the round rod 19. The left end of the reset torsion spring 20 is fixedly connected to the round shell 5. An anti-slip knob 6 is installed on the right end of the protrusion 10. The reset torsion spring 20 provides the automatic reset torque for the protrusion 10. When the operator releases the anti-slip knob 6, the reset torsion spring 20 can drive the protrusion 10 to automatically return to the initial position, realizing quick and automatic unlocking. Multiple guide rods 13 are fixed below the locking rod 8. Multiple U-shaped plates 15 are equidistantly fixed to the right end of the inner wall of the round shell 5. Multiple transition holes 9 are equidistantly provided on the outer circumference of the round shell 5. Multiple round rods 19 pass through multiple transition holes 9 respectively. The guide rods 13 provide precise guidance for the radial movement of the locking rod 8, ensuring that the locking rod 8 can only slide in a straight line and will not deflect or jam, making the locking and unlocking actions smooth and reliable. Multiple clamping rods 8 are set and evenly distributed on the circular shell 5 through the U-shaped plate 15, which can form a multi-point and uniform clamping force, ensuring that the connection between the protective sleeve 4 and the flange 3 is firm and stable, and will not loosen or tilt due to single-point force. The transition hole 9 provides a channel for the circular rod 19 to pass through the wall of the circular shell 5.

[0017] Multiple guide rods 13 are slidably installed in the circular holes of multiple circular hole blocks 11. The ends of multiple first springs 12 away from the circular hole blocks 11 are fixed to the locking rod 8. The first springs 12 ensure that the locking rod 8 can be tightly engaged in the locking groove 7 in the locked state, providing continuous locking force. A sealing ring is fixed to the left end of the protective sleeve 4. The sealing ring is installed at the port of the protective sleeve 4. When the protective sleeve 4 is fitted onto the probe rod 2, it effectively seals the gap between the protective sleeve 4 and the probe rod 2. This prevents dust, moisture, and other contaminants from entering the interior of the protective sleeve 4, protecting the precision components at the end of the probe rod 2.

[0018] As a second embodiment of this utility model: Figure 1 This demonstrates the locked state of the protective sleeve 4. When the protective sleeve 4 needs to be removed, the anti-slip knob 6 is turned clockwise, causing the protrusion 10 and the round rod 19 to rotate. The return torsion spring 20 is twisted by force, and the multiple rollers 18 remain in contact with the surface of the protrusion 10 under the elastic force of the multiple second springs 17. As the protrusion 10 rotates, the multiple rollers 18 roll. When the protruding part of the protrusion 10 contacts the multiple rollers 18, the multiple notched round rods 14 will move along the corresponding transition holes 9. When the multiple second springs 17 are moved, they will be squeezed by the ring 16 and the U-shaped plate 15. When the multiple notched round rods 14 move upward, they will drive the corresponding locking rods 8 to move. At this time, the multiple first springs 12 are stretched, and the multiple locking rods 8 are disengaged from the multiple locking slots 7. Keeping the protrusion 10 stationary, the protective sleeve 4 can be removed. Loosen the anti-slip knob 6, and the reset torsion spring 20 will drive the protrusion 10 to reset. The multiple rollers 18 will contact the concave surface of the protrusion 10, thereby allowing the multiple locking rods 8 to return to their initial state.

[0019] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
