Description

Technical Field

[0001] The utility model relates to the field of negative pressure sensors, in particular to a novel mining pipeline negative pressure sensor. Background Art

[0002] Mining pipelines are pipeline systems specially designed for transporting various fluids underground in coal mines. They play a vital role in the production and safety of coal mines. The types of mining pipelines include but are not limited to water supply and drainage pipelines, gas extraction pipelines, ventilation pipelines, etc. They are responsible for transporting key resources and emissions such as water, air, and gas. When monitoring ventilation tunnels, negative pressure sensors are needed to monitor negative pressure, display the differential pressure value of the measured point in real time, and realize telemetry and detection automation to ensure the normal operation of the ventilation system in the mine and the safety of the gas extraction pipeline.

[0003] During the monitoring process of existing negative pressure sensors, there is usually a certain amount of water vapor inside the ventilation tunnel. After long-term use, a certain amount of water vapor is easily condensed on the surface of the detection rod, interfering with the sensor's signal transmission and detection information, resulting in inaccurate measurement results and reducing the detection accuracy inside the ventilation tunnel.

[0004] Therefore, for the above-mentioned existing negative pressure sensors, after long-term use, a certain amount of water vapor is likely to condense on the surface of the detection rod, interfering with the sensor's signal transmission and detection information, resulting in inaccurate measurement results and reducing the detection accuracy inside the ventilation tunnel. A new type of mining pipeline negative pressure sensor can be designed. The detection rod can be heated after long-term use to prevent water vapor from condensing on the sensor surface, avoid detection errors caused by water vapor, ensure the accuracy of the negative pressure sensor readings, and improve the overall monitoring effect.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] See also Figures 1-4 The utility model provides an embodiment: a new type of mining pipeline negative pressure sensor 201, including a connecting platform 1 and an auxiliary detection component; the outer end of the connecting platform 1 is equipped with an auxiliary detection component for assisting the sensor installation and detection, the auxiliary detection component includes a negative pressure sensor 201, a transmission block 202, a detection rod 203, a fixing frame 204, a heating rod 205, a connecting rod 206, a docking joint 207, a connecting block 209, a battery shell 210, and a transmission rod 211. The negative pressure sensor 201 is located below the connecting platform 1, and a transmission block 202 is provided at the lower end of the negative pressure sensor 201. Two groups of detection rods 203 are provided at the bottom of the transmission block 202. A fixing frame 204 is provided at the rear end of the transmission block 202, and a heating rod 205 is provided inside the fixing frame 204.

[0023] See also Figure 1-Figure 2In this embodiment, a battery shell 210 is provided on the outside of the negative pressure sensor 201, and two groups of batteries are provided inside the battery shell 210. A connecting block 209 is provided at the rear end of the negative pressure sensor 201. The two groups of batteries are electrically connected to the negative pressure sensor 201 through the connecting block 209. By using two groups of batteries, a certain amount of power is provided to the negative pressure sensor 201 as a backup power supply when the connector is short-circuited or power is cut off, ensuring that the negative pressure sensor 201 can still work normally when the main power supply system fails, providing key data for mine safety and extending the effective working time of the sensor. A transmission rod 211 is provided at the bottom of the battery shell 210, and a connector 212 is provided at one end of the transmission rod 211 away from the battery shell 210. A sealing strip is provided on the inner side of the connector 212. By laying a sealing strip inside the connector 212 of the transmission rod 211, the erosion of the connector 207 by moisture and pollution is reduced, the sensor is prevented from power outages and short circuits, and the overall safety is improved.

[0024] See also Figure 1-Figure 3 In this embodiment, a connecting rod 206 is provided at the upper end of the negative pressure sensor 201, and one end of the connecting rod 206 is provided with a threaded head. The connecting rod 206 is combined with the threaded head to be threadedly fixed to the inner wall of the ventilation tunnel, thereby reducing the risk of shaking and falling off, ensuring the long-term stable operation of the sensor, and ensuring the stability and measurement accuracy of the sensor to obtain the best monitoring effect. A plurality of docking joints 207 are provided on the inner wall of the connecting plate 1, and a threaded ring is provided inside the docking joint 207. By adopting a plurality of docking joints 207, the installation angle of the negative pressure sensor 201 is adjusted and fixed, so that it can adapt to different ventilation tunnel structures and monitoring requirements to ensure that it is correctly aligned with the measuring point, ensuring that the sensor can effectively capture the changes in wind flow pressure and improve the accuracy of the data.

[0025] See also Figure 2-Figure 4 In this embodiment, a plurality of sets of positioning bolts 208 are provided inside the connecting plate 1, and the connecting plate 1 is fixedly connected to the tunnel wall through the positioning bolts 208. By preferentially selecting the installation position of the sensor, the sensor is accurately positioned on the inner wall of the ventilation tunnel, reducing the displacement caused by tunnel vibration or external impact, and facilitating the subsequent installation and fixation of the sensor. The outer wall of the negative pressure sensor 201 is symmetrically provided with a plurality of sets of connecting sleeves 213, and the interior of the connecting sleeves 213 is provided with limiting holes. By using the connecting sleeves 213 to fix different equipment according to different detection and use requirements, it adapts to different monitoring environments and conditions, so that the sensor can be used in different systems, thereby improving the versatility of the equipment.

[0026] When working, first prioritize the installation position of the negative pressure sensor 201, and use the positioning bolts 208 in combination with the connecting plate 1 to preliminarily fix it on the inner wall of the ventilation tunnel to reduce displacement caused by tunnel vibration or external impact. After the connecting plate 1 is installed, use multiple sets of docking joints 207 to adjust and fix according to the installation angle of the negative pressure sensor 201 to ensure that it is correctly aligned with the measuring point and ensure that the sensor can effectively capture the change in wind flow pressure. After selecting the installation position, use the connecting rod 206 to connect the threaded head and the docking joint 207 to reduce the risk of shaking and falling off, and ensure the long-term stable operation of the sensor. After the sensor is installed, use the transmission rod 211 in combination with the connecting head 212 to dock with the power supply to power the negative pressure sensor 201 and start the ventilation detection. For the internal situation of the tunnel, when water vapor condenses on the surface of the detection rod 203 after long-term use, the two sets of heating rods 205 are controlled to heat the detection rod 203 to prevent water vapor from condensing on the sensor surface, thereby avoiding detection errors caused by water vapor, and enabling the sensor to provide accurate data in harsh environments, thereby improving the overall monitoring effect. When the connector 212 is short-circuited or power is cut off, two sets of batteries are used to provide a certain amount of power to the negative pressure sensor 201 as a backup power supply, ensuring that the negative pressure sensor 201 can still operate normally when the main power supply system fails, and provide key data for mine safety. After the power is restored, the battery power is replenished while the negative pressure sensor 201 is powered to prepare for subsequent emergencies, thereby ensuring the long-term stable operation of the negative pressure sensor 201.

[0027] Through the above steps, when the negative pressure sensor 201 is used for detection in the ventilation tunnel, two sets of heating rods 205 are used to heat the detection rod 203 to prevent water vapor from condensing on the sensor surface, avoid detection errors caused by water vapor, ensure the accuracy of the readings of the negative pressure sensor 201, and enable the sensor to provide accurate data in harsh environments, improve the overall monitoring effect, and enhance the sensor's adaptability to harsh environments. Secondly, two sets of batteries are used to provide a certain amount of power as a backup power supply for the negative pressure sensor 201 when the connector is short-circuited or the power is cut off, ensuring that the negative pressure sensor 201 can still work normally when the main power supply system fails, providing key data for mine safety and extending the effective working time of the sensor.
