Description

Technical Field

[0001] This invention relates to the field of tunnel ventilation technology, specifically a mobile tunnel face dust transport blocking system. Background Technology

[0002] In tunnel excavation, explosive blasting is often used as a tunneling method. However, this method generates a large amount of dust at the working face, which permeates the tunnel and is difficult to eliminate.

[0003] Therefore, after blasting operations, the tunnel's ventilation system will be forced to perform dust extraction for a certain period of time to remove the dust generated at the tunnel face, thereby ensuring the physical and mental health of personnel entering the tunnel afterwards.

[0004] However, once dust is generated, it spreads throughout the tunnel. The ventilation system cannot completely remove all dust within the mandatory operating time. The presence of residual dust undoubtedly increases the risk of workers contracting dust-related occupational health diseases. Furthermore, the obstruction of vision caused by residual dust increases the probability of accidents, placing workers in a dangerous environment and increasing the economic burden on the company. Therefore, we provide a mobile tunnel face dust transport blocking system. Summary of the Invention

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0043] Please see Figures 1 to 13This invention provides a technical solution: a mobile tunnel face dust transport blocking system, comprising a single-ended tunnel 1, a tunnel face 2, a compressed air system 3, an exhaust system 4, a mobile tunnel dust blocking device 5, a blocking device controller 6, and ground indicator markers 7. The single-ended tunnel 1 is a tunnel under construction, and the tunnel face 2 is the tunnel section under construction. The compressed air system 3 is located on one side wall of the single-ended tunnel 1, and forces fresh air into the tunnel face 2 to ensure that there is qualified fresh air near the tunnel face 2. The compressed air system 3 includes a tunnel forced-in fan 31 and a first air duct 32. The tunnel forced-in fan 31 is connected to the first air duct 32, and the end of the first air duct 32 is close to the tunnel face 2. The distance between the first air duct 32 and the tunnel face 2 is the safe distance for blasting operations. The ventilation system 4 is located on the opposite wall of the single-ended tunnel 1. It concentrates and removes the dust generated by blasting operations near the working face 2 to the outside of the tunnel. The ventilation system 4 includes a tunnel exhaust fan 41 and a second ventilation duct 42. The tunnel exhaust fan 41 is connected to the second ventilation duct 42. The air inlet of the tunnel exhaust fan 41 is close to the working face 2. The distance between the tunnel exhaust fan 41 and the working face 2 is the safe distance for blasting operations. The tunnel mobile dust blocker 5 is installed on the ground of the single-ended tunnel 1 and is located on the central axis of the single-ended tunnel 1. The tunnel mobile dust blocker 5 can automatically reach the working location, detect the dust concentration at the working location, and generate a dust barrier to enter the optimal working state. It can also collect information about the working environment and transmit it to the blocker controller. 6. The tunnel mobile dust blocking device 5 includes a drive system 501, a platform 502, an airflow baffle 503, a first infrared ranging sensor 504, a second infrared ranging sensor 505, a vision sensor 506, a barrier generator 507, a first dust monitor 508, a second dust monitor 509, a control center 510, and a battery 511. The platform 502 is installed above the drive system 501 and is a flat cylindrical shape, serving as the central support for the other components of the tunnel mobile dust blocking device 5. The airflow baffle 503 is installed at both ends of the platform 502 and is embedded within it. It can extend to both sides to the tunnel wall, blocking the gap between the sides of the platform 502 and the ground, preventing dust from passing through the gap. The first infrared ranging sensor 504 is installed on the airflow baffle 503 on the left side of the platform 502 to measure the distance from the left airflow baffle to the left tunnel wall. The second infrared ranging sensor 505 is installed on the airflow baffle 503 on the right side of the platform 502 to measure the distance between the right airflow baffle 504 and the tunnel wall. The vision sensor 506 is installed at the center in front of the platform 502 to capture visual information in front of the tunnel mobile dust blocking device 5. The barrier generator 507 is installed in the center of the platform 502. The barrier generated by the barrier generator 507 is a wind barrier that also blocks the movement of dust, isolating the dust in the space between the working face 2 and the barrier. The dust is then extracted from this space by the exhaust system 4.The first dust monitor 508 is installed at the front left of the platform 502. It monitors the dust concentration in front of the wind barrier generated by the barrier generator 507, collects the monitored dust concentration data, and transmits the dust concentration data to the information display screen 63 of the barrier controller 6. This allows personnel to remotely understand the dust concentration information in the environment where the tunnel mobile dust barrier 5 is located. The second dust monitor 509 is installed at the rear left of the platform 502. It monitors the dust concentration behind the wind barrier generated by the barrier generator 508, collects the monitored dust concentration data, and transmits the dust concentration data to the information display screen 63 of the barrier controller 6. This allows personnel to remotely understand the dust concentration information in the environment where the tunnel mobile dust barrier 5 is located. The control center 510 is installed at the rear center of the platform 502. The battery 511 provides sufficient power to the tunnel mobile dust barrier 5 to support the operation of the instrument. The barrier controller 6 includes a controller body 61, control buttons 62, and an information display screen. The display screen 63 and vision sensor 506 capture visual information about the environment in which the mobile dust barrier 5 is located, transmitting this information to the information display screen 63 of the barrier controller 6. This allows personnel to understand the visual information in the environment where the mobile dust barrier 5 is located. When the automatic control of the mobile dust barrier 5 malfunctions, the control button 62 controls the movement of the drive system 501, the extension and retraction of the airflow baffle 503, and the operation of the barrier generator 507. It also controls the rotation of the vision sensor 506 to collect visual information from different angles. The environmental information collected by the mobile dust barrier 5 is displayed on the information display screen 63. Ground indicator markers 7 are placed on the tunnel surface. Ground indicator markers 7 include movement markers 71 and stop markers 72. The indicator markers 7 are captured by the vision sensor 506 and processed by the control center 510 to control the movement and stop of the mobile dust barrier 5, enabling the mobile dust barrier 5 to automatically move to the designated location.

[0044] The drive system 501 includes a first wheel 5011, a second wheel 5012, a third wheel 5013, a fourth wheel 5014, a first drive motor 5015, a second drive motor 5016, a third drive motor 5017, and a fourth drive motor 5018. The first wheel 5011 is connected to the first drive motor 5015, and is driven by the first drive motor 5015. The second wheel 5012 is connected to the second drive motor 5016, and is driven by the second drive motor 5016. The third wheel 5013... 013 is connected to the third drive motor 5017, which drives the third wheel 5013 to rotate. The fourth wheel 5014 is connected to the fourth drive motor 5018, which drives the fourth wheel 5014 to rotate. The first wheel 5011, the second wheel 5012, the third wheel 5013, and the fourth wheel 5014 do not need to rotate left or right. According to the movement needs, the tunnel mobile dust blocking device 5 can move in eight directions (front, back, right, upper left, lower left, upper right, and lower right) under the coordinated action of the four wheels.

[0045] The airflow baffle 503 includes an outer airflow baffle 5031 and an inner airflow baffle 5032. The inner airflow baffle 5032 is embedded in the outer airflow baffle 5031. The height of the outer airflow baffle 5031 is the same as the height of the platform 502. The height of the inner airflow baffle 5032 is the distance between the bottom of the platform 502 and the ground. When the outer airflow baffle 5031 extends to the tunnel wall, the inner airflow baffle 5032 extends downward from the outer airflow baffle 5031 to the ground and contacts the ground.

[0046] The barrier generated by the barrier generator 507 is a wind barrier. The barrier generator 507 includes a bottom body 50701, a middle body 50702, a top body 50703, a top closing plate 50704, a middle partition 50705, an air inlet 50706, an air outlet 50707, a first roller 50708, a second roller 50709, a third roller 50710, a fourth roller 50711, a fifth drive motor 50712, and a sixth drive motor 50713. The bottom body 50701 is a single, integral body, installed in the center of the platform 502. The middle body 50702 is a modular body, composed of six body shells. When the tunnel is mobile... When the dust blocking device 5 is not in operation, the six middle-layer housings surround the outer side of the bottom housing and are on the same horizontal plane as the bottom housing. When the tunnel-moving dust blocking device 5 is in operation, the six middle-layer housings will move upward from the position of the bottom housing 50701. When the bottom of the middle-layer housing reaches the top of the bottom housing, the middle-layer housings will move inward and align with the position of the bottom housing, forming the middle housing 50702. The top housing 50703 is a combined housing, which is composed of six housings. When the tunnel-moving dust blocking device 5 is not in operation, the six top housings surround the outer side of the middle housing and are on the same horizontal plane as the middle housing.When the tunnel-type mobile dust blocking device 5 is in operation, after the six top-level housing shells are assembled with the middle-level housing 50702, they move upwards from the position of the middle-level housing 50702. When the bottom of the top-level housing shells reaches the top of the middle-level housings, the top-level housing shells move inwards to align with the position of the middle-level housings, thus forming the top-level housing 50703. The top closing plate 50704 is located at the top of the housing and moves upwards with the middle-level housing 50702 and the top-level housing 50703, so that the housing of the barrier generator 507 is in a completely closed state. The middle partition 50705 contains two interlayer partitions, which move upwards with the middle-level housing 50702 and the top-level housing 50703. The upward movement simultaneously separates the first roller 50708, the second roller 50709, the fifth drive motor 50712, the third roller 50710, the fourth roller 50711, and the sixth drive motor 50713, ensuring their operation does not interfere with each other. The air inlet 50706, located on the middle section of the machine body 50702 near the tunnel entrance, allows outside air to enter the barrier generator 507. The air outlets 50707, located on both sides of the machine body facing the tunnel wall, discharge the outside air processed by the rollers, forming a barrier to prevent dust movement. The first roller 50708 is located below the fifth drive motor 50712, and the second roller 50709... 9 is located above the fifth drive motor 50712. The fifth drive motor 50712 drives the first roller 50708 and the second roller 50709 to rotate, treating the outside air entering through the air inlet 50706 and discharging it through the air outlet 50707. This forms a wind barrier on the left side of the barrier generator 507, blocking dust movement. The third roller 50710 is located below the sixth drive motor 50713, and the fourth roller 50711 is located above the sixth drive motor 50713. The sixth drive motor 50713 drives the third roller 50710 and the fourth roller 50711 to rotate, treating the outside air entering through the air inlet 50706 and discharging it through the air outlet 50707. This forms a wind barrier on the left side of the barrier generator 507, blocking dust movement. A wind barrier is formed on the right side of 7 to block the movement of dust. After the first roller 50708, the second roller 50709, the third roller 50710, the fourth roller 50711, the fifth drive motor 50712, and the sixth drive motor 50713 are assembled in the body of the barrier generator 507, they will be pushed upward to the center of the middle body. When the tunnel mobile dust blocking device 5 arrives at the working location and enters the working state, the middle body 50702 and the top body 50703 of the barrier generator 507 are pushed upward, so that the bottom body 50701, the middle body 50702, and the top body 50703 become one unit. The top closing plate 50704 rises to the top of the body, so that the body reaches the closed state.Air enters the barrier generator 507 through the air inlet, and the drive motor rotates the rollers, causing the air inside the barrier generator 507 to rotate. The air is then discharged through the air outlet 507, forming an air barrier that can block dust movement and confine the dust within a certain space.

[0047] The first dust monitor 508 includes a first monitor body 5081, a first normal signal light 5082, a first warning signal light 5083, and a first prohibition signal light 5084. The first normal signal light 5082 is located on the top of the first monitor body 5081, the first warning signal light 5083 is located on one side of the first normal signal light 5082, and the first prohibition signal light 5084 is located on the other side of the first warning signal light 5083. The first monitor body 5081 reflects the dust concentration detected by the first dust monitor 508. The first normal signal light 5082 indicates that the dust concentration is at a safe and acceptable normal level. The first warning signal light 5083 indicates that the dust concentration is about to exceed the safety limit. The first prohibition signal light 5084 indicates that the dust concentration has exceeded the safety limit and that personnel in the current environment will be harmed.

[0048] The second dust monitor 509 includes a second monitor body 5091, a second normal indicator light 5092, a second warning indicator light 5093, and a second prohibition indicator light 5094. The second normal indicator light 5092 is located on the top of the second monitor body 5091, the second warning indicator light 5093 is located to one side of the second normal indicator light 5092, and the second prohibition indicator light 5094 is located to the other side of the second warning indicator light 5093. The second monitor body 5091 reflects the dust concentration detected by the second dust monitor 509. The second normal indicator light 5092 indicates that the dust concentration is at a safe and acceptable normal level, the second warning indicator light 5093 indicates that the dust concentration is about to exceed the safety limit, and the second prohibition indicator light 5094 indicates that the dust concentration has exceeded the safety limit and that personnel in the current environment will be harmed.

[0049] The control center 510 includes a control center body 5101, a motherboard 5102, and a central processing unit 5103. The control center body 5101 is the exterior of the control center 5100, and the motherboard 5102 is installed inside the control center body 5101. The central processing unit 5103 is located above the motherboard 5102. The control center 510 centrally processes the information collected by the first infrared ranging sensor 504, the second infrared ranging sensor 505, the vision sensor 506, the first dust monitor 508, and the second dust monitor 509, so that the control center 510 controls the drive system 501 to automatically run to the designated location, controls the airflow baffle 503 to automatically extend and retract to a suitable position close to the tunnel wall, and controls the barrier generator 507 to automatically run to generate an air barrier of appropriate strength that can block the movement of dust.

[0050] In summary, this mobile tunnel face dust transport blocking system works by deploying ground indicator markers 7 at a safe distance from the blasting operation site within the tunnel. The visual sensor 506 in the mobile dust blocking device 5 detects these markers, and the control center 510 processes the information, automatically driving the mobile dust blocking device 5 to move along the ground indicator markers 7 to the designated working position. When blasting personnel carry explosives to the face for blasting operations, the airflow baffle 503 of the mobile dust blocking device 5 automatically extends to both sides of the tunnel wall under the combined action of the first infrared ranging sensor 504, the second infrared ranging sensor 505, and the control center 510. The middle body 50702, the top body 50703, and the top closing plate 50704 of the barrier generator 507 advance upwards according to a prescribed procedure, completing the full closure of the assembly. After the first dust monitor 508 detects that the dust concentration in the environment exceeds the standard, the control center 510 controls the first roller 50708... The second roller 50709, the third roller 50710, the fourth roller 50711, the fifth drive motor 50712, and the sixth drive motor 50713 operate to form an air barrier covering the entire tunnel cross-section on both sides of the air outlet 50707, blocking dust movement. If the air barrier generated by the barrier generator 507 is insufficient, causing dust to diffuse to the barrier, it will be detected by the second dust monitor 509. The control center 510 will adjust the air barrier generated by the barrier generator 507 based on the monitoring data from the second dust monitor 509. The strength of the wind barrier is such that it can completely block the movement of dust. When the dust concentration detected by the first dust monitor 508 reaches the normal level, the control center 510 controls the airflow baffle 503 and the barrier generator 507 to return to the initial state, and controls the tunnel mobile dust blocking device 5 to return to the starting point. If the automatic control of the control center 510 malfunctions during the operation of the tunnel mobile dust blocking device 5, the staff can operate the blocking device controller 6 to intervene in the tunnel mobile dust blocking device 5.
