Description

Technical Field

[0001] This disclosure relates to the field of tunnel ventilation equipment technology, and in particular to a wind guide device and a tunnel ventilation system. Background Technology

[0002] In underground mining, branch roadways are often opened on the main underground roadway to form a "Y"-shaped roadway, depending on the progress and requirements of underground mining. These branch roadways are typically end-of-line roadways. To ensure mining safety, relevant regulations require a ventilation system to be installed in the main roadway. However, because the branch roadway (end-of-line roadway) is at an angle to the main roadway, fresh air from the ventilation system cannot be effectively exhausted into the branch roadway (end-of-line roadway), thus creating a safety hazard. Therefore, existing technology typically uses windbreaks to separate the branch roadway (end-of-line roadway) into an intake duct and an exhaust duct, guiding fresh air from the main roadway into the intake duct and exhausting it through the exhaust duct, thus creating airflow in the branch roadway (end-of-line roadway). However, using windbreaks presents the following problems: 1. Windbreaks divide branch roadways (end-of-line roadways) into intake and exhaust ducts, affecting the working faces within the branch roadways. In particular, when safety risks arise within the roadways, windbreaks can hinder the escape of workers.

[0003] 2. The windbreaks installed at the intersection of the main roadway and the branch roadway (end-block roadway) are directly placed on the windward side of the ventilation airflow in the main roadway. Due to the obstruction of the windbreaks, the stability of the airflow will be affected, causing problems such as airflow turbulence, and the windbreaks will not be able to guide the airflow to the branch roadway (end-block roadway) effectively.

[0004] Based on the above, the existing technology needs further improvement. Summary of the Invention

[0005] One of the technical problems this disclosure aims to solve is how to avoid the wind deflector affecting the working surface and personnel escape, as mentioned above, and how to improve the air guiding effect.

[0006] To address the aforementioned technical problems, this disclosure provides an air guiding device and a roadway ventilation system, comprising: a separation mechanism, which includes multiple separation units arranged in a row within the blocked roadway to divide the blocked roadway into an air inlet and an air outlet. Each separation unit includes two parallel first columns and a first roller shutter door, with the opposite ends of the roller shutter door slidably mounted on the two first columns to separate or connect the air inlet and air outlet ducts; and an air guiding mechanism, located at the intersection of the blocked roadway and the main roadway, which includes two parallel second... The system consists of columns, a bottom beam, a top beam, a second roller shutter door, and a guide plate. The two ends of the bottom beam are connected to the bottom ends of the two second columns, and the two ends of the top beam are connected to the top ends of the two second columns. The two opposite ends of the second roller shutter door are slidably mounted on the two second columns. One end of the guide plate is slidably connected to the top beam and the bottom beam, and the other end is connected to the ends of the top beam and the bottom beam on the same side via two telescopic rods to adjust the angle between the guide plate and the second roller shutter door, so as to guide the air from the main roadway into the air intake duct. The second column away from the telescopic rods is connected to the first column adjacent to the guide plate mechanism.

[0007] In some embodiments, both the bottom beam and the top beam are provided with slide rails, and one end of the air guide plate is provided with two sliders, which are slidably disposed in the two slide rails respectively.

[0010] In some embodiments, the partition unit further includes two first slide rails, which are arranged parallel to each other on the bottom plate of the end-blocking roadway and perpendicular to the extension direction of the end-blocking roadway. The bottom ends of the two first columns of the partition unit are slidably arranged on the two first slide rails respectively. The air guiding mechanism further includes a second slide rail, which is arranged on the bottom plate at the junction of the end-blocking roadway and the main roadway and is parallel to the first slide rail. The bottom beam is slidably connected to the second slide rail.

[0011] In some embodiments, lighting lamps are provided on both the partition unit and the air guide mechanism.

[0012] In some embodiments, an air detector is provided on the air guide plate.

[0013] In some embodiments, a walkie-talkie is provided on the first column.

[0015] On the other hand, this disclosure also provides a tunnel ventilation system, including the air guiding device of the tunnel ventilation system described above.

[0026] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0027] As mentioned in the background section above, existing technologies typically use baffles to divide branch roadways (end-of-line roadways) into intake and exhaust ducts, directing fresh air from the main roadway into the intake duct and exhausting it through the exhaust duct, thus creating airflow in the branch roadway (end-of-line roadway). However, using baffles can affect the working face within the branch roadway. In particular, when safety risks arise in the roadway, baffles can hinder the escape of workers, and they can also cause turbulence, resulting in poor airflow guidance from the baffles to the branch roadway (end-of-line roadway). Based on the above, the inventors of this application provide an air guiding device and a roadway ventilation system in one or more embodiments. The air guiding device effectively solves the problem of poor air guiding effect to branch roadways (end-of-way roadways) in the prior art through the air guiding plate. When the first and second roller shutters are lowered, the branch roadway (end-of-way roadway) is divided into an air inlet duct and an air outlet duct, realizing the flow of fresh air in the branch roadway (end-of-way roadway). When the first and second roller shutters are retracted, the requirements of the working face of the branch roadway (end-of-way roadway) are met, and the problem of personnel being unable to evacuate quickly in the event of a safety accident is also solved. Thus, one or more problems in the prior art are solved.

[0028] To address the aforementioned technical problems, this invention provides an air guiding device and a roadway ventilation system, such as... Figures 1-3 As shown, it includes: a partitioning mechanism 1, which includes multiple partitioning units 2 arranged in a row within the blocked passageway 3 to divide the blocked passageway 3 into an air inlet duct 4 and an air outlet duct 5. Each partitioning unit 2 includes two parallel first columns 6 and a first roller shutter door 7, with the opposite ends of the roller shutter door slidably mounted on the two first columns 6 to separate or connect the air inlet duct 4 and the air outlet duct 5; and a guide air mechanism 8, which is located at the intersection of the blocked passageway 3 and the main passageway 9. The guide air mechanism 8 includes two parallel second columns 10, a bottom beam 11, a top beam 12, a second roller shutter door 13, and a guide plate 14. The bottom beam 10... The two ends of 1 are respectively connected to the bottom ends of the two second columns 10, the two ends of the top beam 12 are respectively connected to the top ends of the two second columns 10, the two opposite ends of the second roller shutter door 13 are slidably mounted on the two second columns 10, one end of the air guide plate 14 is slidably connected to the top beam 12 and the bottom beam 11, and the other end of it is connected to the ends of the top beam 12 and the bottom beam 11 on the same side by two telescopic rods 15, so as to adjust the angle between the air guide plate 14 and the second roller shutter door 13, so as to guide the air from the main roadway 9 into the air inlet duct 4. The second column 10 away from the telescopic rod 15 is connected to the first column 6 adjacent to the air guide mechanism 8.

[0029] Specifically, during normal production, the first roller shutter 7 and the second roller shutter are in the lowered state. Through the sliding of the air guide plate 14 on the top beam 12 and the bottom beam 11, and the extension and retraction of the telescopic rod 15, the air guide plate 14 and the second roller shutter 13 are positioned at a suitable angle. This allows the fresh air in the main tunnel 9 to be effectively discharged into the air inlet duct 4 and then discharged from the air outlet duct 5, thus creating airflow within the end-of-tunnel 3 and ensuring the ventilation needs of the end-of-tunnel 3 are met. Furthermore, to ensure better airflow within the end-of-tunnel 3, an exhaust fan can be added at the end of the end-of-tunnel 3 (the bend where the air inlet duct 4 and the air outlet duct 5 intersect). To further prevent the formation of turbulence and eddies in the fresh air of the main roadway 9 at the air guide mechanism 8 (turbulence and eddies can cause dust accumulation and dust disasters), multiple ventilation holes can be opened on the second roller shutter door 13. In this way, some of the fresh air is discharged into the other side of the second roller shutter door 13 through the ventilation holes. This also solves the safety problem caused by the second roller shutter door 13 being located on the fresh air passage of the main roadway 9 (blocking the fresh air) and causing excessive wind pressure difference on both sides.

[0030] When connecting the air inlet duct 4 and the air outlet duct 5 according to production needs, and when removing the obstruction of the air guide mechanism 8 on the main roadway 9, the first roller shutter door 7 and the second roller shutter door 13 are retracted. Simultaneously, through the sliding of the baffle plate on the top beam 12 and the bottom beam 11, and the extension and retraction of the telescopic rod 15, the baffle plate forms a 90-degree angle with the second roller shutter door 13 (at this time, the baffle plate is close to the side wall of the main roadway 9 and parallel to it), thus resolving the obstruction of the air guide plate 14 on the main roadway 9. By connecting the air inlet duct 4 and the air outlet duct 5, and removing the obstruction of the air guide mechanism 8 on the main roadway 9, the requirements for equipment and personnel passage and the working face are met. Furthermore, in the event of a disaster, workers can evacuate promptly, avoiding casualties caused by the obstruction of the separation mechanism 1 and the air guide mechanism 8 hindering personnel evacuation.

[0031] Furthermore, the first column 6, the second column 10, the top beam 12 and the bottom beam 11 can be made of steel structure, with fireproof material coated on their surface, and the roller shutter door can be made of fireproof aluminum composite panel.

[0032] Compared with the prior art, the air guiding device of the roadway ventilation system of this application effectively solves the problem of poor air guiding effect to the blocked roadway 3 in the prior art through the air guiding plate 14. When the first roller shutter 7 and the second roller shutter 13 are lowered, the blocked roadway 3 is divided into the air inlet duct 4 and the air outlet duct 5, realizing the flow of fresh air in the blocked roadway 3. When the first roller shutter 7 and the second roller shutter 13 are retracted, the requirements of the working face of the blocked roadway 3 are met, and the problem of personnel being unable to evacuate quickly in the event of a safety accident is also solved.

[0033] In some embodiments, both the bottom beam 11 and the top beam 12 are provided with slide rails (not shown in the figure), and one end of the air guide plate 14 is provided with two sliders (not shown in the figure), which are slidably disposed in the two slide rails respectively. The cooperation between the sliders and the slide rails ensures that the air guide plate 14 slides stably on the bottom beam 11 and the top beam 12.

[0034] In some embodiments, both the top beam 12 and the bottom beam 11 are provided with driving mechanisms, and the driving ends of the two driving mechanisms are respectively connected to two sliders that slide within the slide rail (not shown in the figure). Specifically, the driving mechanism can be a motor, which drives the sliders to slide within the slide rail, saving manpower.

[0035] In some embodiments, a wind pressure sensor (not shown in the figure) is installed on the air guide plate 14. The wind pressure sensor can monitor the wind pressure in the main roadway 9 in real time to ensure the ventilation requirements in the main roadway 9 and the end-block roadway 3. Furthermore, a wind pressure sensor can also be added at the end of the end-block roadway 3 (the bend where the air inlet duct 4 and the air outlet duct 5 meet) to accurately monitor the ventilation volume in the end-block roadway 3.

[0036] In some embodiments, such as Figure 1 As shown, the partition unit 2 also includes two first slide rails 16, which are parallel to each other on the bottom plate of the end-blocking channel 3 and perpendicular to the extension direction of the end-blocking channel 3. The bottom ends of the two first columns 6 of the partition unit 2 are slidably mounted on the two first slide rails 16. The air guiding mechanism 8 also includes a second slide rail 17, which is mounted on the bottom plate at the junction of the end-blocking channel 3 and the main channel 9 and is parallel to the first slide rails 16. The bottom beam 11 is slidably connected to the second slide rail 17. By sliding the partition mechanism 1 on the first slide rail 16 and the air guiding mechanism 8 on the second slide rail 17, the positions of the partition mechanism 1 and the air guiding mechanism 8 can be changed, thereby adjusting the size of the air inlet duct 4 and the air outlet duct 5, and thus meeting the requirements of different working surfaces in the production process.

[0037] In some embodiments, both the partition unit 2 and the air guide mechanism 8 are equipped with lighting lamps. The lighting lamps meet the lighting requirements within the blocked tunnel 3.

[0038] In some embodiments, an air detector is installed on the air guide plate 14. Turbulent airflow can easily occur at the air guide plate 14, potentially leading to gas accumulation. The air detector allows for real-time monitoring of gas concentration, ensuring safe production.

[0039] In some embodiments, a walkie-talkie is installed on the first column 6. The walkie-talkie facilitates communication between the staff of the blocked tunnel 3 and the outside world.

[0040] In some embodiments, the air guide plate 14, the first roller shutter door 7, and the second roller shutter door 13 are all provided with an antistatic coating. The antistatic coating avoids safety accidents caused by static electricity.

[0041] In some embodiments, the air guide device further includes a control mechanism electrically connected to a drive mechanism, a wind pressure sensor, and an air detector, thereby achieving production automation.

[0042] The present invention also provides a tunnel ventilation system, including the air guiding device of the tunnel ventilation system described above. In summary, compared with the prior art, this disclosure provides a wind guide device and a roadway ventilation system. The wind guide device effectively solves the problem of poor wind guiding effect to the blocked roadway 3 in the prior art through the wind guide plate 14. When the first roller shutter 7 and the second roller shutter 13 are lowered, the blocked roadway 3 is divided into an air inlet duct 4 and an air outlet duct 5, realizing the flow of fresh air in the blocked roadway 3. When the first roller shutter 7 and the second roller shutter 13 are retracted, the requirements of the working face of the blocked roadway 3 are met, and the problem of personnel being unable to evacuate quickly in the event of a safety accident is also solved.

[0043] The embodiments of this disclosure have now been described in detail. To avoid obscuring the concept of this disclosure, some details known in the art have not been described. Those skilled in the art can fully understand how to implement the technical solutions disclosed herein based on the above description.
