Description

Technical Field

[0001] This application relates to the field of optoelectronic equipment protection technology, specifically to an infrared camera shield. Background Technology

[0002] With the large-scale construction of new energy power plants (such as solar thermal and photovoltaic), remote infrared monitoring systems have become a key operation and maintenance tool. However, in areas with high temperatures and strong sunlight in summer (such as northwestern my country), infrared cameras are exposed to strong solar radiation for a long time, causing the internal temperature of their external protective housing to rise sharply.

[0003] In existing technologies, conventional protective covers mostly use metal or ordinary engineering plastic shells. Although they have basic waterproof and dustproof functions, they generally have the following problems: severe heat accumulation: the protective cover heats up significantly after absorbing solar radiation, and the internal temperature often exceeds the camera's operating limit (generally 50°C), causing frequent equipment shutdowns or shortened lifespan; unblocked heat conduction path: if the sun visor is in direct contact with the protective cover, heat will be conducted to the camera's core components through the metal bracket; simple heat dissipation design: relying solely on ventilation holes for passive heat dissipation, lacking synergistic optimization with the sun visor structure, resulting in low heat dissipation efficiency; poor adaptability: lacking modular design, it is impossible to adjust the sun visor intensity according to the season or time of day.

[0004] Therefore, a technical solution is needed: a new type of protective cover structure that is easy to maintain, to solve the operational problems of outdoor infrared equipment in extreme heat environments. Utility Model Content

[0005] This application aims to provide an infrared camera shroud that solves the problems of excessive internal temperature caused by solar radiation, unblocked heat conduction paths, low heat dissipation efficiency, and poor adaptability in existing camera shrouds. Through an innovative space isolation shading design, it achieves significant cooling and improved long-term operational stability.

[0006] According to one aspect of this application, an infrared camera shroud is provided, comprising: A first protective cover, the first protective cover being used to house an infrared camera; The second protective cover is disposed above the first protective cover, and the second protective cover is fixed to the first protective cover at multiple points; The third protective cover includes at least one set of side baffles, and the third protective cover is fixed to the second protective cover at multiple points; An air insulation layer is formed between the first shield, the second shield, and the third shield.

[0007] According to some embodiments, the second protective cover has a semi-circular arc structure.

[0008] According to some embodiments, the set of side baffles includes a first side baffle and a second side baffle, the first side baffle and the second side baffle are respectively installed on the upper left and right sides of the second protective cover, and the first side baffle and the second side baffle form an inverted V shape.

[0009] According to some embodiments, the first lateral baffle and the second lateral baffle are foldable structures.

[0010] According to some embodiments, the third shield is made of metal and has a smooth, silver surface.

[0011] According to some embodiments, the third shield is made of engineering plastic, and the surface of the third shield is coated with a heat-reflective coating.

[0029] With the large-scale construction of new energy power plants (such as solar thermal and photovoltaic), remote infrared monitoring systems have become a key operation and maintenance tool. However, in areas with high temperatures and strong sunlight in summer (such as northwestern my country), infrared cameras are exposed to strong solar radiation for a long time, causing the internal temperature of their external protective housing to rise sharply.

[0030] For example, measured data from the Tangshan Haitai 100MW solar thermal power plant showed that the peak temperature inside the original protective cover reached 47.2℃, which was 7.1℃ higher than the ambient temperature, seriously affecting the stability of the equipment. Through the heat conduction path, the temperature of the outer shell of the protective cover exceeded 60℃, and was directly conducted to the front and sides of the camera core component protective cover through the metal bracket, thus absorbing the full spectrum of direct solar radiation.

[0031] Therefore, there is an urgent need for a new type of protective cover structure that is structurally sound, provides efficient heat insulation, and is easy to maintain, in order to solve the operational challenges of outdoor infrared equipment in extreme thermal environments.

[0032] The following description, in conjunction with the accompanying drawings, illustrates exemplary embodiments of this application.

[0033] Figure 1 A schematic diagram of an infrared camera housing according to an example embodiment is shown.

[0034] See Figure 1 According to an example embodiment, the infrared camera housing includes a first housing 101, a second housing 201, and a third housing 301. The first housing 101 houses the infrared camera. The second housing 201 is positioned above the first housing 101 and is fixed to the first housing 101 at multiple points. The third housing 301 includes at least one set of lateral baffles and is fixed to the second housing 201 at multiple points. The specific fixing points are adjusted according to the size of the second housing 201 and the third housing 301. For example, two screw supports are provided on each of the left and right sides of the first housing 101, and the third housing 301 is fixed to the second housing 201 at four points, and the second housing 201 is fixed to the first housing 101 at four points. An air insulation layer is formed between the first housing 101, the second housing 201, and the third housing 301.

[0035] According to some embodiments, the second protective cover 201 has a semi-circular arc structure and is made of lightweight aluminum alloy. A structural schematic diagram of the second protective cover can be found [link to schematic diagram]. Figure 2 .

[0036] According to some embodiments, the third shield is made of metal and has a smooth, silver surface. If the third shield is made of engineering plastic, its surface is coated with a heat-reflective coating. The heat-reflective coating is an aluminum-based or ceramic-based solar radiation reflective material, and a high-reflectivity aluminum-based material surface spraying treatment is performed to enhance the solar radiation reflectivity.

[0037] According to some embodiments, the set of side baffles 301 includes a first side baffle 3011 and a second side baffle 3013. The first side baffle 3013 and the second side baffle 3013 are respectively installed on the upper left and right sides of the second protective cover 201, and the first side baffle 3011 and the second side baffle 3013 form an inverted V shape. The included angle between the first side baffle and the second side baffle is 60° to 90°. The first side baffle and the second side baffle are foldable structures. A schematic diagram of the structure of the first side baffle can be found [see attached diagram]. Figure 3 According to some embodiments, the side baffle has a single panel size of 200×150mm and is fixed to the first shield with M2 / M3 long screws. The side baffle is used to isolate lateral radiation, and an air insulation layer of ≥2cm is reserved between the side baffle and the second shield. The gap of the air insulation layer is maintained by bolt fulcrums, and the thermal conductivity of the bolts is ≤0.3 W / (m·K), ensuring that an air insulation layer is formed between the third shield and the second shield, realizing physical isolation of the heat conduction path.

[0038] According to some embodiments, the first protective cover is made of lightweight aluminum alloy, with an operating temperature range of -20℃ to +50℃, suitable for high-temperature and strong-light outdoor environments. The first protective cover 101 includes a first shielding ring 1011, which is an annular metal ring positioned in front of the lens window of the first protective cover 101. The width of the first shielding ring can be designed according to the size of the infrared temperature measuring camera, for example, 50mm, and the thickness is 1.5mm. It is fixed at four points using M3 screws to block direct sunlight and reduce heat accumulation in front of the window.

[0039] According to some embodiments, the third shield can adopt a modular design, with each component detachably installed via standardized threaded connectors, supporting rapid assembly or disassembly based on seasonal or ambient temperature changes. The shading configuration can be flexibly adjusted according to ambient temperature, solar radiation intensity, and seasonal changes, improving system adaptability and maintenance efficiency. The third shield achieves plug-and-play installation via M2 / M3 standard threaded holes and pre-embedded nuts. Regarding seasonal mode switching: the summer mode can be set to full shading configuration for maximum coverage; the winter mode can remove some side baffles to reduce wind load and allow for moderate warming to prevent condensation.

[0040] This embodiment forms an air insulation layer between the first, second, and third shields, creating a physically isolated "thermal bridge blocking structure." Because air has an extremely low thermal conductivity (approximately 0.026 W / (m·K)), this gap effectively suppresses the conduction of solar radiation heat through the metal to the infrared camera body. Furthermore, the high-reflectivity coating reflects the heat radiated by the shields back into the environment, further reducing net heat exchange and avoiding the thermal bridge effect that makes traditional shading structures increasingly hotter.

[0041] According to some embodiments, the first shield has ventilation holes at the top and / or bottom to form a natural convection heat dissipation channel from bottom to top; the edge of the second shield is in a guide arc shape to guide external airflow to accelerate through the shield surface and improve the overall heat exchange efficiency.

[0042] According to some embodiments, the mounting structure between the third protective cover and the first protective cover has a reserved expansion interface for subsequent integration of micro fans, temperature and humidity sensors or active heat dissipation modules to achieve intelligent temperature control upgrades.

[0043] The infrared camera shroud proposed in this application was tested, and the testing procedure is as follows: Phase 1: Benchmarking (Original Shield) 1. Keep the protective cover in its original state and install it on the concrete block of the infrared camera.

[0044] 2. Choose a sunny date with an outdoor temperature above 40°C.

[0045] 3. Configure the thermometer, verify the time is correct, clear historical data, and keep it powered on. (Complete before 9:00 AM)

[0046] 4. Fix the thermometer to the base of the infrared camera and record temperature data continuously for 48 hours.

[0047] 5. Take out the thermometer at the same time the next day and export the temperature data.

[0048] Phase Two: Testing of Protection Solutions

[0049] 1. Install the infrared camera housing of this application.

[0050] 2. Choose a sunny date with an outdoor temperature above 40°C.

[0051] 3. Configure the thermometer, verify the time is correct, clear historical data, and keep it powered on. (Complete before 9:00 AM)

[0052] 4. Fix the thermometer to the base of the infrared camera and record temperature data continuously for 48 hours.

[0053] 5. Take out the thermometer at the same time the next day and export the temperature data.

[0054] The data records are shown in Table 1.

[0057]

[0058]

[0059] Based on the temperature monitoring data in the table, a detailed analysis was conducted on the cooling effect of the new infrared camera housing: Comparison of highest temperatures: July 28th highest temperature: 47.2℃ (occurred at 17:13 and 17:23); July 30th highest temperature: 43.7℃ (occurred at 17:23 and 17:33), cooling effect: 3.5℃ decrease.

[0060] Average temperature comparison: Based on data from the entire day, the average temperature on July 28 was approximately 42.3℃; the average temperature on July 30 was approximately 38.9℃, with an average temperature drop of approximately 3.4℃.

[0061] Overall temperature variation range: July 28 (before the modification), the temperature variation range inside the protective cover was 35.2℃~47.2℃; July 30 (after the modification), the temperature variation range inside the protective cover was 33.8℃~43.7℃.

[0062] Based on the temperature data from the experiment, the following conclusions can be drawn: the infrared camera housing proposed in this application can effectively cool the camera around the clock. After modification, the housing showed a significant cooling effect during all monitoring periods; the effect was more pronounced during high-temperature periods, with a cooling range of 3.5-5.1℃ during the afternoon high-temperature period. The temperature change was more gradual after the modification, and the temperature fluctuation was reduced, indicating improved thermal stability of the housing. The maximum cooling range was 5.1℃, and the continuous cooling capability maintained a cooling effect of more than 3℃ throughout the day.

[0063] Peak temperature control successfully reduced the highest temperature from 47.2℃ to 43.7℃. Based on data analysis, the newly modified infrared camera housing did indeed have a significant effect on reducing the internal temperature of the equipment. The infrared camera housing modification project using this application achieved significant temperature control results, providing a more suitable temperature environment for equipment operation.

[0064] This technical solution, through scientific testing and rigorous process control, has achieved closed-loop verification from theoretical design to engineering implementation. Actual test data shows that the optimized sunshade and heat dissipation shield significantly outperforms traditional structures in key indicators such as maximum temperature control, temperature difference reduction, and operational stability. It possesses quantifiable, replicable, and scalable technical advantages, making it suitable for thermal management upgrades in the protection of infrared imaging equipment in outdoor high-sunlight environments such as solar thermal power plants, photovoltaic power plants, forest fire prevention, or traffic monitoring.
