Description

Technical Field

[0001] The present invention relates to the technical field of tunnel construction dust reduction, and in particular to an intelligent spray dust reduction system for a high-altitude tunnel working space. Background Art

[0002] High-altitude tunnels refer to tunnels built in areas with higher altitudes. These tunnels are usually located in high mountains, plateaus or under extreme climatic conditions, and face special environmental challenges such as low oxygen, cold, and frozen soil. The construction of high-altitude tunnels not only needs to overcome the limitations of the natural environment, but also needs to solve special problems caused by high altitudes, such as altitude sickness, hypoxia, low temperature, and frozen soil stability.

[0003] Tunnel dust reduction refers to the generation of large amounts of dust during the construction and operation of tunnels due to operations such as drilling, blasting, and loading and unloading of slag. This dust not only poses a threat to the health of construction workers, possibly causing diseases such as pneumoconiosis and silicosis, but the flammable and explosive dust may also cause explosion accidents. In addition, the dust will also pollute the surrounding environment and affect air quality and visibility.

[0004] The existing tunnel spray dust reduction device pressurizes water through a high-pressure pump, and then generates water mist through a high-pressure nozzle to absorb fine dust in the air and humidify the internal space of the tunnel, thereby achieving the purpose of dust reduction. However, during dust reduction, due to special engineering problems in high-altitude areas, low temperature, and low-pressure working environment, the ventilation in the tunnel is poor, the air circulation is slow, and in the cold construction environment, it is easy for water mist to fall on the road surface together with dust. With the effect of low temperature, a thin layer of ice is formed. When subsequent personnel and vehicles enter, the road surface is easy to slip, posing a threat to the personal health of workers and the driving safety of vehicles. At the same time, with the As the workers move forward on the work surface, the dust reduction device is heavy and complicated to move due to the large number of facilities and heavy equipment. It cannot quickly and effectively follow up on the construction of the next work surface, resulting in low work efficiency. Workers inhale dust in the air, which endangers their personal safety. In addition, the transportation of water sources in the plateau is complicated and cannot be recycled, resulting in reduced fogging efficiency of the device and shortened effective working time. At the same time, when dealing with sudden fires and dust explosions inside the tunnel, there is no mobile water source to quickly respond to emergencies, which can easily affect construction costs. Therefore, the present application provides a high-altitude tunnel working space intelligent spray dust reduction system to meet the needs. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide an intelligent spray dust reduction system for high-altitude tunnel working space to solve the existing tunnel spray dust reduction device, which pressurizes water through a high-pressure pump, and then generates water mist through a high-pressure nozzle to absorb fine dust in the air and humidify the internal space of the tunnel, thereby achieving the purpose of dust reduction. However, when performing dust reduction, due to special engineering problems in high-altitude areas, low temperature, and low-pressure working environment, the ventilation in the tunnel is poor, the air circulation is slow, and in the cold construction environment, the water mist is easily caused to fall onto the road surface together with the dust, and a thin layer of ice is formed under the action of the low temperature. When subsequent personnel and vehicles enter When entering, the road surface is easy to slip, posing a threat to the personal health of workers and the driving safety of vehicles. At the same time, as the workers advance on the work surface, the dust reduction device is heavy and complicated to move due to the large number of facilities and heavy equipment. It cannot quickly and effectively follow up the construction of the next work surface, resulting in low work efficiency. Workers inhale dust in the air, which harms their personal safety. In addition, the transportation of water sources in the plateau is complicated and cannot be recycled, resulting in a decrease in the fogging efficiency of the device and a shortened effective working time.

[0016] Optionally, the booster pump, electric push rod, centrifugal pump, dust suction fan and dust indicator are all electrically connected to the control center.

[0017] Compared with the prior art, the present invention has at least the following beneficial effects:

[0018] In the above scheme, by setting up a spray dust reduction component, utilizing the cooperation between the telescopic rod, the booster pump, the extension rod, the gear shaft, the cover plate and the atomizing nozzle, when the worker is working at a certain position, the height of the device is adjusted by adjusting the telescopic rod, so that the spray dust removal component can increase the upper and lower distance between it and the air, and then the extension rod is extended to the worker's working position, and the booster pump is electrically conducted through the control center to control the flow rate of the water flow, so that the atomizing nozzle sprays water mist to form water mist of different dust particle sizes for spraying, so that it can quickly merge with the dust and suspended particles contained in the tunnel air, and then fall to the bottom through the influence of its own blending gravity. At the same time, as the working surface advances, the rotation direction of the gear shaft can be adjusted to increase the spraying angle and area range of its own water mist, so as to improve the effect of tunnel dust reduction, keep the dust content of the working surface low, protect the personal health of workers, and improve the state of the working environment.

[0019] By setting up a dust recovery component, using a recovery plate, an electric push rod, a guide pipe, a nozzle pipe, a dust suction fan, a dust indicator and a dust collection bin, when the spray dust reduction component is in operation, the recovery plate can form a vortex air area at the bottom through the siphon fan wheel at the bottom of itself, and quickly absorb the suspended matter that falls to the bottom, preventing the water mist from falling to the ground and causing icing, keeping the tunnel floor dry, avoiding the occurrence of unexpected situations such as slipping, and in the hot summer, improving the temperature and humidity of the tunnel working surface, providing a comfortable construction environment for the workers, and mobilizing the workers' enthusiasm for work. At the same time, the electric push rod is electrically connected to the control center The connection can adjust the moving coverage distance of the recovery plate according to the spraying area and distance of the atomizing nozzle, so as to absorb the water mist in the air to the greatest extent and avoid the occurrence of ground icing. At the same time, due to the slow air circulation inside the tunnel and the poor dust fluidity, the dust suction fan will generate suction to this area, restraining the dust and suspended particles in the air from pouring into the operating area of ​​the device, accelerating the rapid fusion of water mist and dust, improving the efficiency of dust reduction operations, and providing a good air environment for construction operations. It protects the physical and mental health of workers, increases the working time of workers in a good environment, shortens the construction period, and improves the construction efficiency.

[0020] At the same time, a dust removal and filtering component is set up, so that the recovery disk recycles water, and the output end of the nozzle pipe sprays the water splashing threaded disk. Under the action of its own threaded section, it drives the rotary filter to rotate on the rotating shaft disk. At the same time, the guide pipe at the other end sprays the collected liquid through one end of the filter to the filtrate pipe at the other end, and filters it through the rotary filter to improve the purity of the water source. At the same time, the water droplets generated by the water splashing threaded disk inside the dust removal box absorb and drop the dust sucked into the dust removal box by the dust suction fan, thereby improving the efficiency of dust reduction. When the filtrate pipe transports the filtered liquid and flows back to the telescopic pipe, the diversion pipe diverts the liquid inside the filtrate pipe, so that a small part of the water source flows into the hollow brush rod, and the rotating filter screen is cleaned by the brush. The water utilization and purification construction process improves the water utilization rate and saves water. At the same time, it extends the operating time of the device, increases the effectiveness of the internal environment protection of the tunnel, and improves the operating efficiency. At the same time, the use of emergency fire water pipes also provides a controllable prevention for the occurrence of emergencies. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] like Figures 1 to 11 As shown, an embodiment of the present invention provides an intelligent spray dust reduction system for a high-altitude tunnel working space, comprising a vehicle body 1, a water tank 2 is installed on the top of the vehicle body 1, a dust washing pool 3 is installed at one end of the top of the vehicle body 1, an emergency fire water pipe 4 is installed at the front end of the water tank 2, a water inlet 10 is installed on the top of the water tank 2, a connecting seat 11 is installed at one end of the water tank 2, a dust removal box 9 is installed at one end of the connecting seat 11, and a control center 5 is installed at the front end of the dust removal box 9; it also includes a spray dust reduction component 6, the interior of the connecting seat 11 is sleeved with the spray dust reduction component 6, and the spray dust reduction component 6 is used to perform directional spraying on the dust generated inside the tunnel; it includes a dust recovery component 7, one end of the dust removal box 9 is installed with the dust recovery component 7, and the dust recovery component 7 is used to absorb suspended matter generated by water absorption in the tunnel; it includes a dust removal filter component 8, the interior of the dust removal box 9 is rotatably connected with the dust removal filter component 8, and the dust removal filter component 8 is used to clean the filter screen and filter the water with dust at the same time.

[0042] As an implementation method in this embodiment, Figures 3 to 5As shown, the vehicle body 1 and the bottom end of the dust absorption component 7 are on the same horizontal plane, the bottom of the water storage tank 2 is connected to one end of the dust washing pool 3, and the spray dust reduction component 6 includes a telescopic rod 61, which is installed inside the connecting seat 11. The inside of the telescopic rod 61 is hollow, and a booster pump 62 is installed on the top of the telescopic rod 61. An extension rod 63 is installed at one end of the telescopic rod 61. The extension rod 63 consists of a telescopic long rod and a vertical fixed rod. A latch gear shaft 64 is installed at the bottom of the extension rod 63. The bottom of the latch gear shaft 64 is rotatably connected to a covering plate 65. The top of the covering plate 65 is connected to the two ends of the bottom of the extension rod 63. An atomizing nozzle 66 is installed at the bottom of the covering plate 65. When the telescopic rod 63 is extended, the atomizing nozzle 66 is installed at the bottom of the covering plate 65. The rod 61 rises to the inner wall of the tunnel and stops. At this time, the workers can move freely from the bottom. When the telescopic rod 61 stops, the extension rod 63 extends toward the construction surface and stops at a certain distance from the construction surface to prevent the device from being too close to the construction surface and affecting the workers' working environment. Then, the rotation angle of the gear shaft 64 is adjusted to rotate the cover plate 65 installed at the bottom of the gear shaft 64 and stop rotating after being perpendicular to the ground. When the cover plate 65 is perpendicular to the ground, the booster pump 62 is started through the control center 5 to pressurize the water pipe, so that the water flow is sprayed into the air from the inside of the water storage tank 2 through the atomizing nozzle 66 to absorb and drop the dust and suspended particles inside the tunnel.

[0043] As an implementation method in this embodiment, Figures 6 to 8As shown, the dust recovery component 7 includes a recovery plate 71, which is mounted at one end of the dust removal box 9. The recovery plate 71 is provided with multiple groups, and the multiple groups of recovery plates 71 are slidably connected, and multiple groups of siphon impellers are arranged inside the recovery plate 71, and water pipes are arranged at the bottom of the multiple groups of siphon impellers. An electric push rod 72 is installed at the bottom of the recovery plate 71, and an outlet pipe 74 is installed at one end of the recovery plate 71. A centrifugal pump 73 is installed on the top of the outlet pipe 74. One end of the outlet pipe 74 is connected to the water pipe at the bottom of the multiple groups of siphon impellers, a guide pipe 75 is installed at one end of the outlet pipe 74, and a nozzle pipe 76 is installed at the other end of the outlet pipe 74. One end of the dust removal box 9 A dust suction fan 77 is installed, a dust indicator 79 is installed at one end of the dust suction fan 77, a dust detection rod 78 is installed on one side of the output end of the dust suction fan 77, a conical funnel tube 710 is installed at the bottom of the dust removal box 9, a dust collecting bin 711 is installed at the bottom of the conical funnel tube 710, and the dust collecting bin 711 is arranged at the bottom of the vehicle body 1. When the recovery plate 71 completely covers the ground channel, the spray amplitude radius of the atomizing nozzle 66 is correspondingly covered, so that the recovery plate 71 can capture and absorb the water mist and dust at the bottom of the air to a great extent. At this time, the control center 5 starts the centrifugal pump 73, and the centrifugal pump 73 generates a strong suction force to the recovery plate 71. The bottom water pipe of the siphon fan wheel generates suction, and the siphon fan wheel rotates to generate suction, so that a siphon airflow is generated at the top position of the recovery plate 71. At this time, the recovery plate 71 quickly recovers the water mist, dust and suspended particles on the top of the recovery plate 71. After the water is recovered, it is discharged through the outlet pipe 74 to the inside of the guide pipe 75 and the nozzle pipe 76 at both ends for continuous transportation. When the atomizing nozzle 66 is operating, the dust suction fan 77 is in operation. At this time, the suction force of the dust suction fan 77 pulls the dust and suspended particles inside the tunnel toward the output end of the dust suction fan 77, thereby increasing the contact area between the dust and the water mist in the tunnel and improving the purification efficiency. The dust detection rod 78 detects the dust content entering the output end of the dust suction fan 77, and the data detected by the dust detection rod 78 is transmitted to the dust indicator 79. When the dust indicator 79 receives the data, the control center 5 adjusts the pressure in the pipeline by the booster pump 62 and the size of the water mist particles of the atomizing nozzle 66 through the data in the dust indicator 79, so that the water mist can quickly merge with the dust inside the tunnel, and fall to the bottom through the action of its own gravity. The dust absorbed by the dust suction fan 77 enters the dust removal box 9, settles downward and falls to the conical funnel tube 710, and then slides to the dust collecting bin 711 at the bottom for collection.

[0044] As an implementation method in this embodiment, Figures 7 to 10As shown, the dust removal filter assembly 8 includes a rotating shaft disk 83, which is installed on the top inner wall of the dust removal box 9. A rotating disk filter 82 is installed on the surface of the rotating shaft disk 83. A splashing threaded disk 81 is installed on the outer surface of the rotating disk filter 82. The surface of the splashing threaded disk 81 is installed in the spraying direction of the output end of the nozzle pipe 76. A hollow brush rod 84 is installed on the top inner wall of the dust removal box 9. Multiple groups of brushes are arranged on the surface of the hollow brush rod 84. The multiple groups of brushes fit the filter part on the rotating disk filter 82. A lead ball 85 is installed on the bottom of the hollow brush rod 84. The surface of the disc filter 82 is provided with a filtrate tube 86, and the filtrate tube 86 is provided with multiple groups. The open ends of the multiple groups of filtrate tubes 86 are attached to one end of the rotary disc filter 82 and are on the same axis. The inner wall of the filtrate tube 86 is installed with a diverter tube 87. The top opening of the diverter tube 87 is one-third of the inner wall size area of ​​the filtrate tube 86. The bottom of the diverter tube 87 is installed on the top of the hollow brush rod 84. When the water of the nozzle pipe 76 is sprayed to the dust removal filter assembly 8, the water column is sprayed to the surface of the water splashing threaded disc 81, which is affected by its own threaded section, so that it has the power to rotate, and at the same time When the water column is sprayed onto the surface of the water splashing threaded disk 81, the water diffuses to the surroundings to reduce the dust inside the dust removal box 9. When the water splashing threaded disk 81 rotates, the turntable filter 82 installed inside the water splashing threaded disk 81 rotates on the surface of the rotating shaft disk 83 on the inner wall of the dust removal box 9. At this time, one end of the guide pipe 75 is attached to the turntable filter 82. At the same time, one end of the filtrate pipe 86 is attached to the other end of the turntable filter 82. The water column sprayed from the guide pipe 75 penetrates the turntable filter 82 and flows into the filtrate pipe 86. After being filtered by the turntable filter 82 for multiple times, the water column passes through The filtered water source flows into the top of the telescopic rod 61 and continues to transport water to the atomizing nozzle 66. At the same time, the diverter pipe 87 installed inside the filtrate tube 86 partially intercepts the water and transports it to the inside of the hollow brush rod 84. The water flows along the brush gap to the surface of the brush, and the brush on the surface of the hollow brush rod 84 fits the surface of the filter in the turntable filter 82. The hollow brush rod 84 is vertically downward under the influence of the gravity of the lead ball 85 at the bottom. When the turntable filter 82 rotates, multiple groups of brushes on the surface of the hollow brush rod 84 continuously scrub the rotating surface of the filter.

[0045] As an implementation method in this embodiment, Fig.11 As shown, the booster pump 62 , the electric push rod 72 , the centrifugal pump 73 , the dust suction fan 77 and the dust indicator 79 are all electrically connected to the control center 5 .

[0046] The working principle of the technical solution provided by the present invention is as follows:

[0047] First, move the spray dust suppression device body 1 to the position of the tunnel construction face and stop, connect it to the water inlet 10 through an external water source, and fill the water tank 2 with water. At the same time, close the dust washing pool 3 and the water outlet of the emergency fire hose 4 connected to the bottom of the water tank 2 to prevent water loss, then start the control center 5, check the connectivity with each electronic component, start the spray dust suppression component 6, adjust the telescopic rod 61 on the connecting seat 11, and make the telescopic rod 61 rise to the inner wall of the tunnel and stop. At this time, workers can move freely from the bottom. When the telescopic rod 61 stops, the extension rod 63 extends toward the construction work surface and stops at a certain distance from the construction work surface to prevent the device from being too close to the construction surface and affecting the working environment of the workers. Then, the rotation angle of the gear shaft 64 is adjusted to rotate the cover plate 65 installed at the bottom of the gear shaft 64 and stop rotating after being perpendicular to the ground. When the cover plate 65 is perpendicular to the ground, the booster pump 62 is started through the control center 5 to pressurize the water pipe, so that water flows from the inside of the water storage tank 2 into the air through the atomizing nozzle 66, so as to absorb and drop the dust and suspended particles inside the tunnel.

[0048] When the water mist of the atomizing nozzle 66 absorbs the dust and suspended particles in the air and then falls to the dust recovery component 7, the control center 5 determines the moving distance of the electric push rod 72 by the extension distance of the extension rod 63, so that the recovery plate 71 completely covers the ground channel and covers the spray amplitude radius of the atomizing nozzle 66 accordingly, so that the recovery plate 71 can capture and absorb the water mist and dust at the bottom of the air to a great extent. At this time, the control center 5 starts the centrifugal pump 73, and the centrifugal pump 73 generates a strong suction force, which generates suction force on the bottom water pipe of the siphon fan wheel inside the recovery plate 71. At this time, the siphon fan wheel rotates to generate suction force, so that a siphon airflow is generated at the top position of the recovery plate 71. At this time, the recovery plate 71 quickly recovers the water mist, dust and suspended particles on the top of the recovery plate 71. After the water is recovered, it is discharged to the inside of the guide pipe 75 and the nozzle pipe 76 at both ends through the outlet pipe 74 for continuous transportation. When the head 66 is in operation, the dust suction fan 77 is in operation. At this time, the suction force of the dust suction fan 77 pulls the dust and suspended particles inside the tunnel toward the output end of the dust suction fan 77, thereby increasing the contact area between the dust and the water mist in the tunnel and improving the purification efficiency. At the same time, the dust detection rod 78 detects the dust content entering the output end of the dust suction fan 77, and the data detected by the dust detection rod 78 is transmitted to the dust indicator 79. When the dust indicator 79 receives the data, the control center 5 adjusts the pressure in the pipeline of the booster pump 62 according to the data in the dust indicator 79, and adjusts the size of the water mist particles of the atomizing nozzle 66, so that the water mist can quickly merge with the dust inside the tunnel, and fall to the bottom through the action of its own fusion gravity. The dust absorbed by the dust suction fan 77 enters the dust removal box 9, settles downward and falls to the conical funnel tube 710, and then slides to the dust collecting bin 711 at the bottom for collection.

[0049] When the water source adsorbed in the air passes through the nozzle pipe 76, the water of the nozzle pipe 76 is sprayed to the dust removal filter assembly 8, and the water column is sprayed to the surface of the splashing threaded disk 81. Under the action of its own threaded section, it has the power to rotate. At the same time, when the water column is sprayed to the surface of the splashing threaded disk 81, the water diffuses to the surroundings to reduce the dust inside the dust removal box 9. When the splashing threaded disk 81 rotates, the turntable filter 82 installed inside the splashing threaded disk 81 rotates on the surface of the rotating shaft disk 83 on the inner wall of the dust removal box 9. At this time, one end of the guide pipe 75 is attached to the turntable filter 82. At the same time, one end of the filtrate pipe 86 is attached to the other end of the turntable filter 82. The water column penetrates the turntable filter 82 and flows into the filtrate pipe 86. After being filtered by the turntable filter 82 for multiple times, the filtered water source flows into the top of the telescopic rod 61 and continues to supply water to the atomizing nozzle 66. At the same time, the diversion pipe 87 installed inside the filtrate pipe 86 partially intercepts the water and transports it to the inside of the hollow brush rod 84. The water flows along the brush gap to the surface of the brush, and the brush on the surface of the hollow brush rod 84 fits the surface of the filter in the turntable filter 82. The hollow brush rod 84 is vertically downward under the influence of the gravity of the lead ball 85 at the bottom. When the turntable filter 82 rotates, the brushes on the surface of the multiple groups of hollow brush rods 84 continuously scrub the rotating filter surface.
