Their failure will directly lead to equipment damage, production interruption, and system performance degradation. In harsh working conditions such as high temperature and corrosion, it is especially necessary to overcome the technical bottlenecks of protection, heat dissipation, and response speed.

[0003] In the existing technology, temperature monitoring devices deployed in high-temperature, dusty, humid or corrosive environments such as mechanical equipment, power equipment and industrial pipelines generally suffer from problems such as sacrificing heat conduction efficiency in the sealing structure and lag in response due to the lack of effective integrated protection design, which leads to the degradation of measurement accuracy and ultimately affects the temperature monitoring results. Utility Model Content

[0004] The purpose of this invention is to provide a temperature monitoring structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a temperature monitoring structure, comprising a protective box and a temperature detection unit, wherein the temperature detection unit is fixedly installed inside the protective box, the protective box is provided with two sets of symmetrically distributed first mounting frames, each first mounting frame having a ventilation window, a cover fixedly installed inside the first mounting frame, a blower head fixedly installed inside the cover, a second mounting frame fixedly installed on the first mounting frame, a rotating frame rotatably installed on the second mounting frame, a filter screen embedded in the rotating frame, the filter screen corresponding to the cover, the cover fitting against the inner side of the filter screen, a third mounting frame fixedly installed on the second mounting frame, a mounting ring rotatably installed on the third mounting frame, a brush rotatably installed on the mounting ring, the brush fitting against the outer surface of the filter screen.

[0006] As a further preferred embodiment of this technical solution, a first toothed ring is sleeved on the rotating frame, and a drive wheel is rotatably mounted on the second mounting frame, the drive wheel being engaged with the first toothed ring.

[0007] As a further preferred embodiment of this technical solution, a second toothed ring is sleeved on the mounting ring, a first toothed rack is slidably mounted in the third mounting frame, the first toothed rack is meshed with the second toothed ring, a sliding rod is fixedly mounted in the third mounting frame, and a connecting rod is rotatably mounted on the first toothed rack.

[0008] As a further preferred embodiment of this technical solution, the first rack is slidably sleeved with the slide rod, and a spring is sleeved on the slide rod. The spring is provided in two sets, and the two sets of springs are symmetrically distributed. The two ends of the two sets of springs are respectively fixedly connected to the first rack and the third mounting frame.

[0009] As a further preferred embodiment of this technical solution, a crank is rotatably mounted within the third mounting frame, and the crank is rotatably connected to the end of the connecting rod away from the first rack via a rotating shaft.

[0010] As a further preferred embodiment of this technical solution, a gear is sleeved on the brush, a second rack is slidably installed inside the mounting ring, the second rack is meshed with the gear, a cylinder is fixedly installed inside the mounting ring, the second rack is fixedly connected to the output end of the cylinder piston rod, and a scraper corresponding to the brush is fixedly installed on the third mounting frame, with the brush and scraper fitting together.

[0011] This utility model provides a temperature monitoring structure, which has the following beneficial effects:

[0012] (1) Through the synergistic effect of the rotatable filter and the blower head, this utility model can effectively protect the protective box from dust, impact and air, while significantly improving the thermal response speed and measurement accuracy of the temperature detection unit. The symmetrically arranged filter structure provides the necessary physical protection and air circulation channel for the protective box. The rotatable design of the filter, together with the built-in blower head, can efficiently remove the dust attached to the inner surface of the filter, effectively avoiding the problem of reduced heat conduction efficiency and accumulated thermal resistance at the shell interface caused by dust accumulation in traditional sealed protection, thereby ensuring that the temperature detection unit can quickly and accurately perceive the environment.

[0013] (2) This utility model achieves deep cleaning of the outer surface of the filter screen and continuous effective operation of the brush by using a combination of oscillation and rotation brush mechanism and its self-cleaning design. The brush oscillates along the outer surface of the filter screen under the drive of the mounting ring. Its own rotational motion not only enhances the cleaning effect, but more importantly, through cooperation with the fixed scraper, it automatically scrapes off the dust and dirt accumulated on the brush during the oscillation process, effectively preventing the brush from clogging itself, ensuring the continuous unobstructed air passage of the filter screen and the maintenance-free nature of the entire cleaning system during long-term operation.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] This utility model provides a technical solution: such as Figure 1 and Figure 2 As shown, in this embodiment, a temperature monitoring structure includes a protective box 1 and a temperature detection unit 2. The temperature detection unit 2 is fixedly installed inside the protective box 1. The protective box 1 has two symmetrically distributed first mounting frames 3. The first mounting frames 3 have ventilation windows 4. A cover 5 is fixedly installed inside the first mounting frames 3. A blower head 6 is fixedly installed inside the cover 5. A second mounting frame 7 is fixedly installed on the first mounting frames 3. A rotating frame 8 is rotatably installed on the second mounting frame 7. A filter screen 9 is embedded in the rotating frame 8. The filter screen 9 is correspondingly set with the cover 5, and the cover 5 is attached to the inner side of the filter screen 9. The third mounting frame 12 is fixedly installed on the second mounting frame 7. The mounting ring 13 is rotatably installed on the third mounting frame 12. The brush 21 is rotatably installed on the mounting ring 13 and is attached to the outer surface of the filter screen 9. The first toothed ring 10 is sleeved on the rotating frame 8. The drive wheel 11 is rotatably installed on the second mounting frame 7 and is engaged with the first toothed ring 10. The symmetrically arranged filter screen 9 can rotate under the drive of the rotating frame 8. When the surface of the filter screen 9 is covered with dust due to the ventilation requirements of the protective box 1, the fixedly installed blower head 6 continuously or periodically blows high-pressure gas into its inner side. By utilizing the relative movement between the rotating filter screen 9 and the blown airflow, the dust particles accumulated on the inner surface of the filter screen 9 are efficiently peeled off and removed, ensuring that the airflow channel required by the temperature detection unit 2 inside the protective box 1 is unobstructed, while maintaining its effective protection against impact, dust and rapid thermal response capabilities.

[0021] like Figure 3 and Figure 4As shown, a second toothed ring 14 is sleeved on the mounting ring 13. A first rack 15 is slidably mounted inside the third mounting frame 12, and the first rack 15 meshes with the second toothed ring 14. A slide rod 16 is fixedly mounted inside the third mounting frame 12. A connecting rod 18 is rotatably mounted on the first rack 15, and the first rack 15 is slidably sleeved with the slide rod 16. A spring 17 is sleeved on the slide rod 16. Two sets of springs 17 are provided, and the two sets of springs 17 are symmetrically distributed. The two ends of the two sets of springs 17 are fixedly connected to the first rack 15 and the third mounting frame 12, respectively. A crank 19 is rotatably mounted inside the third mounting frame 12, and the crank 19 is connected to the connecting rod 18 via a rotating shaft. The end of rod 18 away from the first rack 15 is rotatably connected. A gear 22 is sleeved on the brush 21. A second rack 23 is slidably installed inside the mounting ring 13, and the second rack 23 meshes with the gear 22. A cylinder 24 is fixedly installed inside the mounting ring 13, and the second rack 23 is fixedly connected to the output end of the piston rod of the cylinder 24. A scraper 20 corresponding to the brush 21 is fixedly installed on the third mounting frame 12, and the brush 21 is fitted with the scraper 20. The mounting ring 13 reciprocates under the action of a drive mechanism such as crank 19-connecting rod 18-first rack 15, driving the brush 21 on it to sweep along the outer surface of the filter screen 9. At the same time, the brush 21 itself rotates around its axis under the drive of the gear 22 and second rack 23 mechanism, enhancing the brushing effect on the outer surface of the filter screen 9. During the reciprocating swing of the brush 21, its bristles continuously adhere to and scrape against the scraper 20 fixedly installed on the third mounting frame 12, automatically removing the dust and dirt accumulated on the brush 21 itself, realizing real-time self-cleaning of the brush 21, and ensuring long-term effective cleaning performance.

[0022] This utility model provides a temperature monitoring structure, the specific working principle of which is as follows: The symmetrically arranged filter screens 9 can rotate under the drive of the rotating frame 8. When dust is adsorbed on the surface of the filter screen 9 due to the ventilation requirements of the protective box 1, the fixedly installed blower head 6 continuously or periodically blows high-pressure gas into its inner side. By utilizing the relative movement between the rotating filter screen 9 and the blown airflow, the dust particles accumulated on the inner surface of the filter screen 9 are efficiently peeled off and removed, ensuring that the airflow channel required by the temperature detection unit 2 inside the protective box 1 is unobstructed, while maintaining its effective protection, namely anti-collision, dustproof and rapid thermal response capabilities. The mounting ring 13 reciprocates under the action of the drive mechanism, namely the crank 19, connecting rod 18 and first rack 15 mechanism, driving the brush 21 on it to sweep along the outer surface of the filter screen 9. At the same time, the brush 21 itself rotates around the axis under the drive of the gear 22 and second rack 23 mechanism, enhancing the brushing effect on the outer surface of the filter screen 9. During the reciprocating swing of the brush 21, its bristles continuously adhere to and scrape against the scraper 20 fixedly installed on the third mounting frame 12, automatically removing the dust and dirt accumulated on the brush 21 itself, realizing real-time self-cleaning of the brush 21, and ensuring long-term effective cleaning performance.
