Description

Technical Field

[0001] The invention relates to the technical field of infrared monitors, in particular to an infrared monitor for coal mines and a monitoring system thereof. Background Art

[0002] In coal mine production, several kilometers long coal conveyor belts are used to transport coal to the destination. During the transportation process, belt deviation, belt tearing, belt scratching, belt overload, belt friction, coal spontaneous combustion and belt fire and breakage, resulting in boiler coal shortage, unit shutdown, ore compression and even major safety accidents are common. Using infrared temperature measurement technology, a stable, complete and accurate mine belt transportation status monitoring and accident warning system has been established. It can dynamically monitor the operating parameters of the mine belt in transportation, monitor the regional temperature during belt transportation in real time, collect and analyze various temperature index parameters, and realize the visualization of hidden fault areas, including motor temperature, belt speed, belt deviation, belt tearing, belt fire and other high-temperature anomaly identification and detection, and diagnose and identify the system according to the analysis results. Infrared thermal imagers are already common infrared monitoring technology for coal mines.

[0003] Dust on the infrared thermal imager's lens will affect infrared imaging. Dust will reduce the light transmittance and clarity of the infrared thermal imager, thus affecting the image quality. Specifically, dust will hinder the passage of light through the lens, resulting in a decrease in the brightness and contrast of the image, and may even cause blurring and distortion. Dust on the infrared thermal imager's lens 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, dust on the lens will cause the transmission of infrared energy to be blocked, thereby affecting the accuracy of temperature measurement. In addition, dust will also cause spots or blurs in the captured image, affecting the clarity and detail of the image. The production environment of coal mines is relatively complex. Although most of them are underground environments with high humidity, there is still a lot of dust. This dust will fall on the lens of the infrared thermal imager, thus affecting the normal use of the infrared thermal imager. In addition, the coal mining process may also contain 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, the lens of the infrared thermal imager will be directly blocked, affecting the real-time monitoring results of the infrared thermal imager.

[0048] In summary, during use, the protective member 5 is installed inside the mounting assembly 6, and the cleaning assembly 4 is arranged on the side wall of the protective member 5. The protective member 5 is used to protect the internal infrared thermal imager 3, so that the dust in the working area of ​​the coal mine is isolated by the protective member 5 to avoid the situation where the monitoring effect is not accurate enough due to direct contact between the dust and the infrared thermal imager 3. During use, the heat dissipation mechanism 7 can be used to blow and dissipate heat for the infrared thermal imager 3 inside the protective member 5. During the blowing process, the airflow acts on the turbine blades 62, so that the entire mounting mechanism is affected by the airflow and rotates. The mounting mechanism drives the protective member 5 to rotate, so that the surface of the protective member 5 can contact with the cleaning assembly 4 to achieve the self-cleaning function. By setting a detachable sealing plate 24, it can The infrared thermal imager 3 and the cleaning component 4 and other structures are installed using the opening position, and after the installation is completed, they are sealed using the sealing plate 24. The installation component 6 is used to install the protective member 5 during use. The bottom end of the protective member 5 is in contact with the first bearing sleeve 65, so the second bearing sleeve 68 and the first bearing sleeve 65 provided can reduce the friction during the rotation process. The transparent cover 51 of the protective member 5 is made of germanium glass, and the infrared thermal imager 3 is covered inside. It is worth noting that since the infrared thermal imager 3 needs to radiate infrared rays during use, the use of transparent glass of ordinary materials or other materials will have an attenuation effect on the infrared light, so germanium glass is used here, which has good light transmittance in the 2-16μm band, and has stable chemical properties and is not easy to react with metal oxides. The transparent cover 51 can react with compounds, acidic substances, air and water, and an optical film is coated on the germanium glass, which can greatly increase the transmittance of infrared rays and reduce the surface reflectivity. When installing the transparent cover 51, it only needs to be inserted into the inside of the rotating cylinder 61, and then the protrusion 53 and the groove 63 on the rotating cylinder 61 can be engaged with each other to achieve installation. When the heat dissipation mechanism 7 blows air into the inside, it will directly act on the turbine blades 62 to make it rotate, and then the airflow will enter the inside of the transparent cover 51 through the air inlet 64, thereby cooling the infrared thermal imager 3 inside the transparent cover 51. When the heat dissipation mechanism 7 is in use, the heat dissipation fan 71 is directly started to guide the external airflow into the connecting cylinder 74, and then the connecting cylinder 74 enters the upper accommodating chamber 21 to act on the turbine blades 62. The air on the blades 62 then enters the transparent cover 51 through the air inlet 64. The top filter 75 can filter the dust. The air outlet 28 is opened at the bottom of the installation area 25, so that the airflow entering the transparent cover 51 can come out from the air outlet 28, so as to take away the heat. A rotatable rotating plate 76 is arranged at the position of the air outlet 28. The rotating 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 cooling fan 71 will become stronger, so that the airflow entering the transparent cover 51 can blow the rotating plate 76 outward, so as to open the air outlet 28. When heat dissipation is not required, the wind speed of the cooling fan 71 remains stable, and there will be no large airflow causing the rotating plate 76 to open.The air outlet 28 is thus closed by the rotating plate 76, and no dust enters the interior. When the cleaning assembly 4 is in use, water is added to the interior of the water storage chamber 23 so that the water can enter the water guide pipe 44. The water guide pipe 44 has a small diameter, and a small water flow enters the water guide pipe 44 from the interior of the water storage chamber 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, which is mounted on the rotating cylinder 61 and rotated by the cooling fan 71 and the turbine blades 62, so that the transparent cover 51 can pass through the cleaning sponge 41 and enter the water guide shell 43. To achieve the purpose of automatic cleaning, the cleaning sponge 41 absorbs the water flow in the water pipe 44 little by little to enhance the cleaning effect of the transparent cover 51. When the cleaning sponge 41 is completely soaked in water, it can also play a certain blocking function, and will not allow the water in the water storage chamber 23 to flow down without restriction. The scraper 42 can scrape the transparent cover 51 after the cleaning sponge 41 cleans it, thereby reducing the 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 accumulation of dust on the surface of the transparent cover 51, which affects the use of the infrared thermal imager 3 The bottom of the transparent cover 51 is tightly connected with the sealing sleeve 67. When the transparent cover 51 rotates, the first bearing sleeve 65 can reduce the friction, and the sealing sleeve 67 can play a sealing function to prevent the cleaning sponge 41 from flowing into the transparent cover 51 when cleaning the transparent cover 51. By setting the arc hole 26, the water stains on the transparent cover 51 can flow down from the position of the arc hole 26. The 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 temperature monitor itself monitored by the internal temperature measurement module to the PC terminal. The terminal is used for real-time viewing by workers. The alarm module is used to send out an alarm when the ambient temperature monitoring result exceeds the set value. The infrared temperature measurement module is set inside the infrared temperature monitor. The infrared temperature measurement module 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 connected to the control module by electrical signals. The cooling fan 71 is also connected to the control module by electrical signals. Therefore, when the temperature inside the infrared thermal imager 3 itself exceeds the set value, the control module can control the cooling fan 71 to accelerate the heat dissipation.
