Description

Technical Field

[0001] The present invention relates to the technical field of infrared monitors, and in particular to a coal mine infrared monitor and its monitoring system. Background Art

[0002] Dust on the lens of an infrared thermal imager will affect infrared imaging. Dust will reduce the light transmittance and clarity of the infrared thermal imager, thereby affecting the imaging quality. Specifically, dust will block the passage of light through the lens, resulting in a decrease in the brightness and contrast of the image, and even possible blurring and distortion. Dust on the lens of the infrared thermal imager will affect the use effect, that is, dust and dirt will reduce the light transmittance of the lens, thereby affecting the measurement accuracy and image quality of the infrared monitor. Specifically, the dust on the lens will cause the obstruction of infrared energy transmission, thereby affecting the accuracy of temperature measurement. In addition, dust will also cause spots or blurring in the captured image, affecting the clarity and detail performance of the image.

[0003] The coal mine production environment is relatively complex. Although it is mostly an underground environment with high humidity, there are still a large amount of dust. These dusts will fall on the lens of the infrared thermal imager, thereby affecting the normal use of the infrared thermal imager. Moreover, during the coal mine processing process, there may also be steam, which will directly form an obstacle layer in front of the infrared thermal imager. In the prior art, a cleaning structure is set in front of the lens, but each time it is cleaned, it will directly block the lens of the infrared thermal imager, affecting the real-time monitoring results of the infrared thermal imager.

[0048] In summary, during use, the protective component 5 is installed inside the installation component 6, and the cleaning component 4 is arranged on the side wall of the protective component 5. The protective component 5 is used to protect the internal infrared thermal imager 3, so that the dust in the coal mine working area is isolated by the protective component 5, avoiding the situation that the monitoring effect is not accurate enough due to the direct contact between the dust and the infrared thermal imager 3. During use, the heat dissipation mechanism 7 can blow air to dissipate heat from the infrared thermal imager 3 inside the protective component 5. During the blowing process, the air flow acts on the turbine blades 62, causing the entire installation mechanism to rotate under the influence of the air flow. The installation mechanism drives the protective component 5 to rotate, so that the surface of the protective component 5 can come into contact with the cleaning component 4, realizing the self-cleaning function. By setting the detachable sealing plate 24, structures such as the infrared thermal imager 3 and the cleaning component 4 can be installed through this opening position, and after installation, it is blocked by the sealing plate 24. The installation component 6 is used to install the protective component 5 during use. The bottom end of the protective component 5 contacts the first bearing sleeve 65. Therefore, the second bearing sleeve 68 and the first bearing sleeve 65 provided can reduce the friction force during rotation. The transparent cover 51 of the protective component 5 is made of germanium glass, and the infrared thermal imager 3 is covered inside. It should be noted that since the infrared thermal imager 3 needs to emit infrared rays during use, ordinary transparent glass or other materials will have an attenuation effect on infrared light. Therefore, germanium glass is used here. It has good light transmission performance in the 2-16μm band, and its chemical properties are stable, not easy to react with metal oxides, acidic substances, air and water. Moreover, by coating an optical film on the germanium glass, the transmittance of infrared rays can be greatly increased, and the surface reflectivity can be reduced. When installing the transparent cover 51, it only needs to be inserted into the inside of the rotating cylinder 61, and then the convex block 53 and the groove 63 on the rotating cylinder 61 are engaged with each other to complete the installation. When the heat dissipation mechanism 7 blows air into the inside, it will directly act on the turbine blades 62 to make them rotate, and then the air flow will enter the inside of the transparent cover 51 through the air inlet hole 64, so as to cool the infrared thermal imager 3 inside the transparent cover 51. During use, the heat dissipation mechanism 7 can directly start the heat dissipation fan 71 to introduce the external air flow into the connecting cylinder 74, and then enter the upper accommodation cavity 21 from the connecting cylinder 74. After acting on the turbine blades 62, it enters the transparent cover 51 through the air inlet hole 64. The top filter screen 75 provided can play the role of filtering dust. By opening the air outlet hole 28 at the bottom of the installation area 25, the air flow entering the inside of the transparent cover 51 can come out from the air outlet hole 28, realizing the purpose of taking away the heat. The position of the air outlet hole 28 is provided with a rotatable turning plate 76. The turning plate 76 rotates through the rotating shaft 78 and is connected by a torsion spring 77. When heat dissipation is required, the wind speed of the heat dissipation fan 71 will become stronger, so that the air flow entering the inside of the transparent cover 51 can blow the turning plate 76 outwards, realizing the purpose of opening the air outlet hole 28. When heat dissipation is not required, the wind speed of the heat dissipation fan 71 remains stable, and there will be no large air flow to cause the turning plate 76 to open.Thus, the air outlet hole 28 is in a state of being closed by the rotating plate 76, and no dust will enter the interior. During the use of the cleaning component 4, water is added into the interior of the water storage cavity 23, so that the water can enter the water guide pipe 44. The diameter of the water guide pipe 44 is relatively small, and a thin water flow enters the water guide pipe 44 from the interior of the water storage cavity 23, and then enters the interior of the water guide shell 43, and is absorbed by the cleaning sponge 41. The cleaning sponge 41 is in contact with the transparent cover 51. The transparent cover 51 is installed on the rotating cylinder 61 and rotates by means of the cooling fan 71 and the turbine blade 62. Thus, the transparent cover 51 can pass through the cleaning sponge 41, thereby achieving the purpose of automatic cleaning. The cleaning sponge 41 absorbs the water flow in the water guide pipe 44 little by little to enhance the cleaning effect on the transparent cover 51. When the cleaning sponge 41 is completely soaked with water, it can also play a certain plugging function, preventing the water in the water storage cavity 23 from flowing down unrestrictedly. The provided scraping strip 42 can scrape the transparent cover 51 after being cleaned by the cleaning sponge 41, thereby reducing the situation of water stains on the surface, making the transparent cover 51 in front of the infrared thermal imager 3 in a relatively clean state, and reducing the situation where the use of the infrared thermal imager 3 is affected due to dust accumulation on the surface of the transparent cover 51. The bottom of the transparent cover 51 is tightly connected to the sealing sleeve 67. When the transparent cover 51 rotates, the first bearing sleeve 65 can play a role in reducing friction, and the sealing sleeve 67 can play a sealing function to prevent water stains from flowing in when the cleaning sponge 41 is cleaning the transparent cover 51. By providing the arc-shaped hole 26, the water stains on the transparent cover 51 can flow down from the position of the arc-shaped hole 26. The provided inclined surface 66 can reduce the accumulation of water stains. The communication module transmits the ambient temperature monitored by the infrared temperature measurement module and the temperature of the infrared thermal imager itself monitored by the internal temperature measurement module to the PC terminal for the worker to view in real time. The alarm module is used to issue an alarm reminder when the monitoring result of the ambient temperature exceeds the set value. The infrared temperature measurement module is arranged inside the infrared thermal imager and is used to monitor the temperature of the environment in the monitoring area and obtain an infrared monitoring image. The internal temperature measurement module is used to monitor the temperature inside the infrared thermal imager 3 itself and is electrically connected to the control module. The cooling fan 71 is also electrically connected to the control module. Thus, when the temperature inside the infrared thermal imager 3 itself monitored exceeds the set value, the control module can control the cooling fan 71 to accelerate heat dissipation.
