[0037] The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0038] Referring to Figures 1-5 The embodiment discloses a protective structure for protecting an infrared thermal imager body 13, specifically an online infrared thermal imager protective cabin structure, which comprises a cabin body 22, a gas conveying device and a protective cover 9 mounted on the cabin body 22, an outer cabin 6 is formed between the protective cover 9 and the cabin body 22, an inner cabin 7 is arranged in the cabin body 22, and a heat insulation cavity 29 is arranged between the outer cabin 6 and the inner cabin 7.

[0039] The thermal imager body 13 and a temperature and humidity sensor 14 are mounted in the inner cabin 7, a front end cover 3 corresponding to the thermal imager body 13 is arranged on the cabin body 22; a gas cylinder 15 is mounted in the outer cabin 6, a shutter cover 1 is connected to the driving end of the gas cylinder 15, and the gas cylinder 15 is used for driving the shutter cover 1 to rotate; a first connector 16 for connecting with the gas outlet end of the gas conveying device is mounted on the outer cabin 6.

[0040] The front end cover 3 is provided with a purge groove 28 in communication with the heat insulation cavity 29, the gas outlet end of the first connector 16 is connected with a three-way connector, and the three-way connector is used for inputting gas into the heat insulation cavity 29 and the gas cylinder 15.

[0041] In the embodiment, the temperature and humidity sensor 14 installed in the inner cabin 7 is used to detect the temperature and humidity of the inner cabin 7 and send the detected data to the control system arranged at the remote end. The temperature and humidity sensor 14 is a conventional detection device in the prior art, and the specific structure and connection relationship with the control system are not described here. The front end cover 3 is provided with a slot corresponding to the lens installed in the thermal imager body 13. The slot is provided with a lens protection sheet 18 and a compression ring 4. The lens protection sheet 18 is installed in the slot through the compression ring 4 and protects the lens. The shutter cover 1 is used to shield the slot, thereby further protecting the lens. The gas supply device inputs the filtered and pressure- maintained gas flow into the three-way joint through the first joint 16. The gas outlet end of the three-way joint is connected with the heat insulation cavity 29 and the air cylinder 15 respectively. The gas flow output by the gas supply device is sequentially divided into the air cylinder 15 and the heat insulation cavity 29 through the first joint 16 and the three-way joint. The gas entering the air cylinder 15 can drive the air cylinder 15 to rotate the shutter cover 1, thereby driving the shutter cover 1 to open and close through the air cylinder 15, so that the shutter cover 1 is opened when the thermal imager body 13 monitors and takes pictures, and is closed when it does not work, thereby realizing opening and closing with use and stopping. The thermal imager body 13 is better shielded and isolated, and physical protection is more effectively provided. The gas flow entering the heat insulation cavity 29 can accelerate the air flow around the inner cabin 7 and the outer cabin 6, quickly take away the hot air emitted around the inner cabin 7 and the outer cabin 6, introduce cold air with lower temperature at the same time, maintain a larger temperature difference, improve the heat dissipation efficiency, and effectively cool the inner cabin 7 and the outer cabin 6. The gas flow input into the heat insulation cavity 29 is blown out through the blowing groove 28 arranged on the front end cover 3 after dissipating heat from the inner cabin 7 and the outer cabin 6, blows off the dust adhered to the lens installed in the thermal imager body 13, and avoids that the dirty lens affects the monitoring effect of the thermal imager body 13. The air cylinder 15 is installed with an air cylinder bracket 10, and the air cylinder 15 is installed in the outer cabin 6 through the air cylinder bracket 10. In the embodiment, the gas supply device is a conventional gas source device in the prior art, and the air cylinder 15 is a conventional rotary swing air cylinder 15 in the prior art.

The second joint 17 is used to connect the circuit of each element in the outer cabin 6 and the inner cabin 7. The first joint 16 and the second joint 17 are metal gland heads with waterproof, dustproof and sealing functions in the prior art, thereby effectively improving the moisture-proof and dust-proof effect of the protective cabin.

[0043] In some embodiments, the first joint 16 and the second joint 17 are respectively connected with a corrugated pipe 21, and the corrugated pipe 21 is connected with a junction box 23 at the end away from the first joint 16 and the second joint 17. The corrugated pipe 21 is a metal pipe easy to bend and install. A gas pipe for connecting with the air inlet end of the first joint 16 is installed in the corrugated pipe 21 installed on the first joint 16, and the end of the gas pipe away from the first joint 16 is connected with a gas supply device. A core wire for connecting with elements in the outer cabin 6 and the inner cabin 7 is installed in the corrugated pipe 21 connected with the second joint 17, and the end of the core wire away from the outer cabin 6 and the inner cabin 7 is connected with the junction box 23. The corrugated pipe 21 connecting the cabin body 22 and the junction box 23 can facilitate the installation of the cabin body 22 and the protective cover 9, and the corrugated pipe 21 can prevent the gas pipe and the core wire from deforming, breaking or loosening, thereby ensuring the safe and stable transmission of the gas flow and the power. The corrugated pipe 21 for connecting with the first joint 16 is provided with a gas path support 11, and the gas path support 11 is installed in the outer cabin 6 and used for supporting and fixing the corrugated pipe 21.

The rotating unit 24 is rotatably mounted on the fixed base plate 26 through the center pin 25. The rotating unit 24 is designed with a scale with a division value of 5 degrees, supporting the cabin 22 to rotate around the center pin 25 within a range of 180 degrees. The rotating unit 24 is provided with a first arc-shaped groove, and the fixed base plate 26 is provided with a first fixed bolt hole corresponding to the first arc-shaped groove. A first fixed bolt is installed in the first fixed bolt hole for fixing the rotating unit 24 rotated to a predetermined angle. The fixed base plate 26 is designed with a second arc-shaped groove, so that the protective cabin can rotate along the second arc-shaped groove. The fixed base plate 26 is provided with a second fixed bolt hole, and a second fixed bolt is installed in the second bolt hole for fixing the fixed base plate 26.

[0048] In some embodiments, the inner cabin is provided with a guide ring corresponding to the thermal imager body 13. The guide ring can guide and position the lens installed in the thermal imager body 13, so that the thermal imager body 13 can be accurately focused and positioned during use, improving the imaging quality.

[0049] In some embodiments, the universal support 19 is provided with a limiting groove, and the bottom end of the cabin 22 is provided with a limiting hole for cooperating with the limiting groove. A limiting bolt is installed in the limiting hole. In this embodiment, the limiting groove is in a rice-shaped groove structure. The intersection of the rice-shaped groove structure allows the cabin 22 to be finely adjusted in position in multiple directions, such as horizontal, vertical, or diagonal directions. Through the cooperation of the limiting bolt and the rice-shaped groove structure, the user can easily adjust the planar position of the cabin 22 to meet the positioning requirements of different working conditions.

[0050] In some embodiments, the cabin 22 is connected with a mounting plate 12, and the thermal imager body 13 and the temperature and humidity sensor 14 are mounted on the mounting plate 12. A clearance area is formed between the mounting plate 12 and the cabin 22, which is used to accommodate the limiting bolt to facilitate the installation of the limiting bolt to fix the cabin 22.

[0051] In some embodiments, the exhaust end of the purge groove 28 is connected with a wind deflector 30, which is inclined to the direction of the lens installed in the thermal imager body 13. In this embodiment, the airflow blown out of the purge groove 28 contacts the wind deflector 30 and flows towards the lens installed in the thermal imager body 13 under the guidance of the wind deflector 30, thereby further improving the cleaning effect and efficiency of the airflow on the dust adhering to the lens.
