Description

Technical Field

[0001] The utility model relates to the technical field of temperature monitoring of surrounding rock in mine roadways, and particularly relates to a monitoring device for the heat-adjusting circle of surrounding rock in a metal mine roadway. Background Art

[0002] During the process of mine exploitation, with the increase of the exploitation depth, the high-temperature problems faced by the mine become more and more serious. These problems are mainly concentrated in the following aspects:

[0003] Increase in geothermal temperature: The deeper the exploitation depth of the mine, the higher the geothermal temperature will be. The increase in geothermal temperature directly leads to the increase in the temperature of the surrounding rock of the mine roadway, thereby affecting the air flow temperature inside the mine.

[0004] Increase in the temperature of the surrounding rock of the roadway: With the increase of the mine depth, the rate of increase in the temperature of the surrounding rock also accelerates. This not only makes the working environment in the roadway more severe, but also leads to the increase in the air flow temperature, further deteriorating the air quality and working conditions in the mine.

[0005] Mine heat damage problems: The heat dissipation of the surrounding rock is the main reason for the increase in the air flow temperature in the mine, especially in the horizontal roadway, and the heat dissipation effect of the surrounding rock is more significant. With the increase of the exploitation depth, the proportion of heat dissipation of the surrounding rock also increases, resulting in the aggravation of the mine heat damage problems.

[0006] Production difficulties and safety threats: Under high-temperature conditions, the labor productivity of miners will decrease, and at the same time, it will pose a threat to the life safety of underground workers. The high-temperature environment not only affects work efficiency, but also may cause health problems such as heat stroke, increasing the risk of accidents.

[0007] Basis for heat parameter prediction and air conditioning: Understanding the temperature distribution law in the heat-adjusting circle of the surrounding rock is of great significance for predicting the heat dissipation amount from the surrounding rock to the air flow, calculating the heat parameters of the roadway air flow, and air conditioning in the mine.

[0008] Therefore, the high-temperature problems faced by the mine are becoming increasingly serious when the exploitation depth increases, and the enhancement of the heat dissipation effect of the surrounding rock is the main reason, which poses a significant threat to the safe production of the mine and the health of miners.

[0037] The following will disclose multiple embodiments of the present utility model with illustrations. For the sake of clear description, many physical details will be described together in the following narrative. However, it should be understood that these physical details are not used to limit the present utility model. That is to say, in some embodiments of the present utility model, these physical details are unnecessary.

[0038] In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement.

[0039] Please refer to Figure 1 、 Figure 2 、 Figure 3 As the mining depth of the mine increases, the ground temperature continuously rises, and the temperature of the surrounding rock 3 of the roadway and the air flow temperature will also continuously increase, thus causing production difficulties. Under high-temperature conditions, the increase in the air flow temperature in the deep mine will make the working environment worse, reduce the labor productivity of miners, and pose a threat to the life safety of underground workers.

[0040] Mine heat damage has increasingly become an urgent problem affecting the safe and efficient production of mines. Among the heat sources in mines, the increase in the dry and wet temperatures of the air flow in the horizontal roadway is mainly caused by the heat dissipation of the surrounding rock 3; and as the mining depth increases, the proportion of heat dissipation from the surrounding rock 3 is larger. Therefore, studying the temperature distribution law in the heat regulation circle of the surrounding rock 3 is the basis for mastering the heat dissipation amount of the surrounding rock 3 to the air flow, predicting and calculating the thermal parameters of the roadway air flow, and air conditioning in the mine.

[0041] Based on this, the present application provides a monitoring device for the heat regulation circle of the surrounding rock of a metal mine roadway, including a PPR pipe 4 inserted into the inner side of a borehole 9, and an infrared temperature measuring device 8 installed on the inner side of the PPR pipe 4;

[0042] One end of the infrared temperature measuring device 8 is provided with a wire 5, and the other end of the wire 5 is connected to a monitoring component 1, and the outer side of the monitoring component 1 is installed at the end of the surrounding rock 3;

[0043] The outer side of the PPR pipe 4 is attached to the inner wall of the drill hole 9 through the expansion foam 7;

[0044] A fixed distance is maintained between the infrared temperature measuring device 8 and the inner side of the PPR pipe 4, and the hole air 10 is filled at this distance for cooperating with the infrared temperature measuring device 8 to detect the temperature.

[0045] One or more drill holes 9 are formed on the inner wall of the surrounding rock 3, and these drill holes 9 are used to place the monitoring device; a temperature measuring hole 6 is formed inside the drill hole 9 for detecting the temperature of the surrounding rock 3. The diameter and depth of the drill hole 9 should be designed according to the actual situation of the mine and the monitoring requirements to ensure that the heat adjustment circle area of the surrounding rock 3 can be accurately covered.

[0046] The temperature measuring hole 6 is formed inside the drill hole 9, and these temperature measuring holes 6 are used to detect the temperature of the surrounding rock 3. The number and distribution of the temperature measuring holes 6 should cover different positions of the surrounding rock 3 in order to obtain representative temperature data.

[0047] The PPR pipe 4 (polypropylene pipe) is inserted inside the drill hole 9. The PPR pipe 4 has good high temperature resistance and corrosion resistance and is suitable for the mine environment. The length and diameter of the PPR pipe 4 should be designed according to actual needs to ensure that the infrared temperature measuring device 8 can be accommodated.

[0048] The infrared temperature measuring device 8 is installed inside the PPR pipe 4 for non-contact detection of the temperature of the surrounding rock 3. The infrared temperature measuring device 8 can quickly and accurately measure the temperature change of the surrounding rock 3 without directly contacting the surrounding rock 3.

[0049] One end of the infrared temperature measuring device 8 is connected to the monitoring component 1 through the wire 5. The monitoring component 1 is installed at the end of the surrounding rock 3 and is responsible for receiving and processing the data transmitted by the infrared temperature measuring device 8. The monitoring component 1 can include a data recorder, a display and a communication module to transmit the data to the mine control system.

[0050] The outer side of the PPR pipe 4 is attached to the inner wall of the drill hole 9 through the expansion foam 7. The expansion foam 7 has good heat insulation performance, can effectively reduce the heat conduction inside and outside the drill hole 9, and maintain the accuracy of the temperature measurement inside the PPR pipe 4.

[0051] A fixed distance is maintained between the infrared temperature measuring device 8 and the inner side of the PPR pipe 4, and the hole air 10 is filled at this distance. As a medium for heat conduction, the air can cooperate with the infrared temperature measuring device 8 to detect the true temperature of the surrounding rock 3 and avoid measurement errors caused by direct contact at the same time.

[0052] By drilling holes 9 in the inner wall of the surrounding rock 3 and using PPR pipes 4 and infrared temperature measuring devices 8, the accurate measurement of the temperature of the surrounding rock 3 can be achieved. This method avoids the limitations of traditional temperature measurement methods and can more accurately reflect the actual temperature state of the surrounding rock 3. The use of PPR pipes 4 and the filling of expansion foam 7 can effectively cope with the high temperature and corrosive environment in the mine, improving the durability and reliability of the equipment. The infrared temperature measuring device 8 is connected to the monitoring component 1 through a wire 5, which can monitor the temperature of the surrounding rock 3 in real time and transmit the data to the mine control system. This helps the mine management personnel to timely understand the temperature change situation and make corresponding adjustments and decisions.

[0053] Due to the adoption of non-contact temperature measurement technology, the infrared temperature measuring device 8 has low maintenance requirements and relatively low failure rates. This reduces the maintenance cost and equipment downtime, improving the operation efficiency of the mine. Accurately monitoring the temperature of the surrounding rock 3 can help the mine management personnel predict and prevent heat damage problems caused by high temperature, thereby improving the safety of the miners' working environment and reducing the accident risk caused by high temperature.

[0054] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 , and sealant mud 2 is filled parallel to the inner wall of the surrounding rock 3 on the outside of the drill hole 9 to prevent the air 10 in the hole from flowing.

[0055] One or more drill holes 9 are opened on the inner wall of the surrounding rock 3. The size of the drill hole 9 should match the outer diameter of the PPR pipe 4, and ensure that the depth of the drill hole 9 is sufficient to accommodate the entire measuring device.

[0056] Sealant mud 2 is filled in the space between the inner wall of the drill hole 9 and the surrounding rock 3. The sealant mud 2 is a material with excellent sealing performance, which can effectively prevent the air 10 in the hole from flowing. Its main components usually include clay, minerals, and cement, etc., and have good fluidity and hardening performance.

[0057] Insert the PPR pipe 4 into the drill hole 9. The outside of the PPR pipe 4 is in close contact with the sealant mud 2 to ensure that there is no gap between the pipe and the sealant mud 2, thereby effectively isolating the air circulation between the outside air and the inside of the drill hole 9.

[0058] Install the infrared temperature measuring device 8 inside the PPR pipe 4. The infrared temperature measuring device 8 maintains a fixed distance from the inner side of the PPR pipe 4, and the air 10 in the hole is filled at this distance for temperature measurement. The outside of the PPR pipe 4 is attached to the inner wall of the drill hole 9 through the expansion foam 7 to further enhance the sealing and heat insulation properties.

[0059] One end of the infrared temperature measuring device 8 is connected to the monitoring component 1 through a wire 5. The monitoring component 1 is installed at the end of the surrounding rock 3 and includes a temperature measuring display screen and a power supply device, which is responsible for receiving and processing the data transmitted by the infrared temperature measuring device 8. The monitoring component 1 can include data recording, display, and communication modules to ensure accurate data transmission and processing.

[0060] The filling of the sealing mud 2 effectively prevents the circulation of the air 10 in the hole, reducing the interference of the external air on the temperature measurement in the drill hole 9. This sealing measure ensures the accuracy and stability of the measurement data.

[0061] The sealing performance of the sealing mud 2 prevents the air convection inside and outside the drill hole 9, reducing the error in temperature measurement. When used in conjunction with the infrared temperature measuring device 8, it can more accurately reflect the actual temperature of the surrounding rock 3.

[0062] Due to the sealing characteristics of the sealing mud 2, the temperature environment inside the drill hole 9 is more stable, reducing the temperature drift caused by changes in the external environment. This helps in the long-term stable monitoring and analysis of the temperature changes of the surrounding rock 3.

[0063] During the filling process of the sealing mud 2, the loss of the air 10 in the hole is effectively prevented, enabling the infrared temperature measuring device 8 to measure in a stable air environment. This is crucial for obtaining the true temperature data of the surrounding rock 3.

[0064] The use of the sealing mud 2 reduces potential problems caused by air flow, such as moisture, corrosion, etc., thereby increasing the lifespan and reliability of the measuring device. This also reduces the maintenance cost and downtime of the equipment.

[0065] Accurate temperature measurement can provide real-time and reliable data, helping the mine management personnel to conduct effective heat hazard analysis and preventive measures. This improves the production efficiency and safety management level of the mine.

[0066] Please refer to Figure 4 、 Figure 5 、 Figure 6 and Figure 7 , the PPR pipe 4 includes a pipe body 41. One or more ribs 43 are arranged in a circular array on the outer side of the pipe body 41 with the central axis of the pipe body 41 as the center. A filling groove is arranged between every two ribs 43, and the filling groove is in contact with the expansion foam 7.

[0067] Two symmetrically arranged strip holes 42 are opened on the outer side of the pipe body 41. Slide rails 44 are symmetrically arranged on both sides of the inner wall of the strip holes 42, and a plastic plate 45 is slidably connected to the inner side of the slide rails 44.

[0068] The main function of the pipe body 41 is to accommodate the infrared temperature measuring device 8 and ensure the stability and accuracy of the temperature measuring device.

[0069] The purpose of setting the convex strips 43 is to increase the contact area between the pipe body 41 and the hole-sealing mud 2, thereby improving the fitting property between the pipe body 41 and the inner wall of the drilling hole 9.

[0070] A filling groove is arranged between every two convex strips 43. The function of the filling groove is to accommodate the expanding foam 7. The design of the filling groove ensures the uniform distribution of the expanding foam 7 and enhances the sealing performance and heat insulation performance of the PPR pipe 4.

[0071] Two symmetrically arranged strip-shaped holes 42 are formed on the outer side of the pipe body 41. The main function of the strip-shaped holes 42 is to provide space for the sliding connection of the plastic plate 45 and at the same time allow the installation and operation of the monitoring component 1.

[0072] Slide rails 44 are arranged on both sides of the inner wall of the strip-shaped hole 42. The plastic plate 45 is slidably connected to the inner side of the slide rails 44. The slide rail 44 system enables the plastic plate 45 to slide within the strip-shaped hole 42, thereby realizing the adjustment and fixation of the plastic plate 45.

[0073] The plastic plate 45 is slidably connected to the slide rails 44 and is used to cover or seal the strip-shaped hole 42 to protect the internal infrared temperature measuring device 8 from the external environment. The adjustment and fixation of the plastic plate 45 can be carried out as needed to ensure the reliability and stability of the measuring device.

[0074] The design of the convex strips 43 and the filling grooves can effectively increase the contact area and fitting property between the PPR pipe 4 body and the hole-sealing mud 2. This structure improves the sealing performance, reduces the air circulation in the drilling hole 9, and thus ensures the accuracy of temperature measurement.

[0075] The filling of the expanding foam 7 in the filling groove improves the heat insulation performance of the PPR pipe 4. This helps to keep the temperature inside the pipe body 41 stable, reduces the interference of the external temperature on the internal infrared temperature measuring device 8, and thus improves the temperature measurement accuracy.

[0076] The design of the strip-shaped holes 42 and the slide rail 44 system provides a convenient operation space, making the installation, adjustment, and maintenance of the monitoring component 1 more convenient. The slide rail 44 system allows the sliding and adjustment of the plastic plate 45, so that the infrared temperature measuring device 8 can be easily replaced or maintained when needed.

[0077] The plastic plate 45 can effectively protect the infrared temperature measuring device 8 from the external environment, such as dust, moisture, etc. through the slide rail 44 system. This helps to extend the service life of the device and maintain its stable measurement performance.

[0078] Please refer to Figure 4 、 Figure 5 、 Figure 6 and Figure 7, a centering component 12 is arranged inside the pipe body 41. The middle part of the centering component 12 is clamped with the infrared temperature measuring device 8 to keep the infrared temperature measuring device 8 in a centered position.

[0079] The centering component 12 includes two symmetrically arranged arc-shaped plates 123. An accommodating cylinder 124 is arranged on the outer side of the arc-shaped plate 123, and a telescopic rod 122 is installed inside the accommodating cylinder 124.

[0080] One end of the telescopic rod 122 is provided with a contact block, and this contact block contacts with the inner wall of the pipe body 41 to limit the infrared temperature measuring device 8.

[0081] The centering component 12 includes two symmetrically arranged arc-shaped plates 123. The arc-shaped plates 123 are used to fit the inner wall of the PPR pipe 4 body, so that the infrared temperature measuring device 8 can be stably centered inside the pipe body 41. The curvature of the arc-shaped plates 123 should match the inner diameter of the pipe body 41 to ensure a tight fit.

[0082] One accommodating cylinder 124 is arranged on the outer side of each arc-shaped plate 123. The accommodating cylinder 124 is used to accommodate and fix the telescopic rod 122. Its design purpose is to provide a stable structural support, so that the telescopic rod 122 can slide freely inside while maintaining the stability of the overall structure.

[0083] The telescopic rod 122 is installed inside the accommodating cylinder 124. The telescopic rod 122 can perform telescopic movement inside the accommodating cylinder 124 to adjust and fix the position of the infrared temperature measuring device 8. The length of the telescopic rod 122 can be adjusted as needed to ensure that the infrared temperature measuring device 8 can be accurately located at the center of the pipe body 41.

[0084] One end of the telescopic rod 122 is provided with a contact block, and the contact block contacts with the inner wall of the pipe body 41 to limit the position of the infrared temperature measuring device 8 and ensure that it remains in the central area of the pipe body 41. The design of the contact block enables it to closely fit the inner wall of the pipe body 41 to prevent the infrared temperature measuring device 8 from shifting or shaking.

[0085] By adjusting the length of the telescopic rod 122, the position of the temperature measuring device can be accurately adjusted according to the size of the infrared temperature measuring device 8 and the inner diameter of the pipe body 41. The design of the arc-shaped plates 123 and the accommodating cylinders 124 provides stable support to ensure that there will be no shaking or deviation during the adjustment process.

[0086] The design of the centering component 12 ensures that the infrared temperature measuring device 8 remains centered inside the pipe body 41. This centered design helps to improve the measurement accuracy of the temperature measuring device and avoid measurement errors caused by position deviation.

[0087] The combined design of the arc-shaped plate 123, the receiving cylinder 124, and the telescopic rod 122 enhances the stability of the infrared temperature measuring device 8 within the pipe body 41. The tight contact between the contact block and the inner wall of the pipe body 41 prevents the displacement or vibration of the temperature measuring device, thereby improving the overall stability and reliability of the equipment.

[0088] The adjustment function of the telescopic rod 122 allows users to easily adjust the position of the infrared temperature measuring device 8 according to actual needs. This adjustment ability makes the installation and maintenance work easier and improves the operation convenience of the equipment.

[0089] Maintaining the centered position of the infrared temperature measuring device 8 helps to obtain more accurate temperature data. The temperature measuring device is at the center of the pipe body 41, reducing the error caused by the measurement angle deviation, thereby improving the temperature measurement accuracy.

[0090] The design of the centering component 12 can adapt to infrared temperature measuring devices 8 of different sizes and specifications. By adjusting the length of the telescopic rod 122, it is possible to adapt to a variety of different models and sizes of temperature measuring devices, improving the versatility of the equipment.

[0091] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 , a spring 125 is provided between the telescopic rod 122 and the receiving cylinder 124, and both ends of the spring 125 are in contact with one end of the telescopic rod 122 and the inner bottom of the receiving cylinder 124 respectively.

[0092] A soft board 121 is provided on the inner side of the arc-shaped plate 123, and the soft board 121 is in contact with the outer side of the infrared temperature measuring device 8.

[0093] A spacing is maintained between the two ends of the two arc-shaped plates 123, and a temperature measuring area 11 is provided at this spacing, and the temperature measuring area 11 corresponds to the plastic plate 45 one by one.

[0094] The centering component 12 includes two arc-shaped plates 123, and soft boards 121 are provided on the inner sides of these arc-shaped plates 123. The inner curvature of the arc-shaped plate 123 matches the inner diameter of the pipe body 41 to ensure that the soft board 121 can be in good contact with the outer side of the infrared temperature measuring device 8.

[0095] A spacing is maintained between the two ends of the two arc-shaped plates 123. This spacing design is used to provide a temperature measuring area 11, enabling the infrared temperature measuring device 8 to perform effective measurements within this area.

[0096] The flexible board 121 inside the arc-shaped board 123 is made of a soft material and has good elasticity, enabling it to closely fit the outer side of the infrared temperature measuring device 8. The function of the flexible board 121 is to improve the stability and sealing performance of the contact surface, ensuring that the measurement data of the infrared temperature measuring device 8 is not interfered with by the outside world.

[0097] A spring 125 is arranged between the telescopic rod 122 and the receiving cylinder 124. One end of the spring 125 contacts one end of the telescopic rod 122, and the other end contacts the inner bottom of the receiving cylinder 124. The function of the spring 125 is to provide additional pressure, enabling the telescopic rod 122 to stably hold the infrared temperature measuring device 8 at the central position of the pipe body 41.

[0098] The elasticity of the spring 125 can be adjusted as needed to adapt to infrared temperature measuring devices 8 of different sizes, ensuring its stability within the pipe body 41.

[0099] A temperature measuring area 11 is arranged at the spacing maintained between the two arc-shaped boards 123. The temperature measuring area 11 is the position where the infrared temperature measuring device 8 performs temperature measurement, corresponding one-to-one with the plastic board 45 inside the pipe body 41. This design ensures that the measurement area of the infrared temperature measuring device 8 matches the position of the plastic board 45, thereby improving the measurement accuracy.

[0100] Install the spring 125 between the telescopic rod 122 and the receiving cylinder 124, and adjust the elasticity of the spring 125 to adapt to different operation requirements. The flexible board 121 inside the arc-shaped board 123 contacts the outer side of the infrared temperature measuring device 8, and through the action of the spring 125, the temperature measuring device is stabilized within the set temperature measuring area 11.

[0101] The design of the temperature measuring area 11 ensures that the infrared temperature measuring device 8 can perform measurements at an accurate position. At the same time, the design of the plastic board 45 can correspond one-to-one with the temperature measuring area 11, further improving the overall measurement accuracy of the device.

[0102] The setting of the flexible board 121 contacts the outer side of the infrared temperature measuring device 8, ensuring a stable contact surface for the infrared temperature measuring device 8, reducing the interference of external factors on the measurement data, and thus improving the measurement accuracy.

[0103] The use of the spring 125 provides stable pressure, keeping the telescopic rod 122 and the infrared temperature measuring device 8 in the central position. In this way, the stability of the temperature measuring device within the pipe body 41 is significantly improved, reducing the measurement errors caused by the deviation of the device position.

[0104] The design of the arc-shaped board 123 and the temperature measuring area 11 ensures the accurate position of the infrared temperature measuring device 8 within the pipe body 41. The maintained spacing provides a dedicated measurement area, aligned with the position of the plastic board 45, further enhancing the reliability of the temperature measurement data.

[0105] The elasticity of the spring 125 can be adjusted according to different measurement requirements to adapt to infrared temperature measuring devices 8 of different specifications and models.
