Description

Technical Field

[0001] The invention relates to the technical field of tunnel construction, and in particular to a tunnel construction dust prevention and suppression device. Background Art

[0002] With the rapid development of highway tunnels in my country, the number and mileage of tunnel projects have increased dramatically. At present, the main construction method of tunnels in my country is drilling and blasting. After the tunnel is blasted, a large amount of dust will be generated in the face. Due to the limited ventilation capacity, the dust in the tunnel cannot be discharged in time, which will greatly reduce the visibility in the tunnel, affecting the construction safety and posing a great threat to the health of the construction workers. In addition, there are frequent slag discharge and concrete transport vehicles in the tunnel cross passage, which generates many pollution sources such as exhaust gas and vehicle dust, and the air quality in the tunnel is poor, which affects the safety of vehicle traffic, so that the difficulty of construction is increased, the danger increases, and the respiratory health of the workers is seriously affected.

[0003] At present, the common method of dust treatment is to lay air ducts in the tunnel and use high-pressure fans to blow away the dust. However, when the tunnel is long, this method has a very poor dust reduction effect. Alternatively, spray pipelines are laid in the tunnel to carry out water sprinkling operations, which collides with the dust in the air and condenses into large particles. The water molecules fall under the action of their own gravity, thereby playing a certain role in reducing the dust.

[0004] However, the installation position of the existing atomizing nozzles is fixed, and the space inside the tunnel is large, so the space for the water curtain formed by the atomizing nozzle spray is limited. In addition, the dust content in different areas of the tunnel is different, and it is impossible to accurately reduce the dust in areas with higher content. The overall spraying is relatively scattered, making it difficult for the water mist and dust to fully contact and combine, which not only leads to poor dust reduction effect, but also serious waste of water resources.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] For example, see Figure 1-7 The present invention provides a tunnel construction dust prevention and suppression device, comprising a pipe body 1, an outer wall of the pipe body 1 is rotatably connected to an outer cover ring 2, and an outer wall of the outer cover ring 2 is fixedly connected to a flow shell 3, and a side wall of the flow shell 3 is fixedly connected to a cylinder 4;

[0032] A swing injection mechanism 5 is provided on one end surface of the outer cover ring 2 .

[0033] Further, the swing spray mechanism 5 includes a driving motor 501, and the output shaft at one end of the driving motor 501 is fixedly connected to a driving disk 502, and the outer wall of the driving disk 502 is fixedly connected to collision columns 503 at equal distances, and the end surface of the outer cover ring 2 facing the driving motor 501 is fixedly connected to a fixing column 504 at equal distances corresponding to the collision column 503, and a cavity 8 is opened inside the outer cover ring 2, and a through hole 505 is opened on the outer wall of the tube body 1 corresponding to the cavity 8, and the tube body 1 is connected to the inner wall of the cavity 8 through the through hole 505, and the bottom of the flow shell 3 is threadedly connected to an atomizing nozzle 9, and the atomizing nozzle 9 is connected to the inner wall of the cavity 8 through the flow shell 3;

[0034] Furthermore, the dust detector 601, the fan 602, the coil 605, the adsorption column 604 and other components are all existing technology products and can be purchased and used in major markets. Therefore, the specific working principles of the above components will not be further described here;

[0035] In this embodiment, in actual use, according to the specific conditions of tunnel construction and the characteristics of dust distribution, several positions of the equipment can be reasonably arranged on the pipe body 1 to cooperate with the swing direction to ensure that the spray range covers the entire construction area. Then, when performing dust removal, first open the valve of the pipe body 1 to allow water to circulate and transport in the pipe body 1, and then the outer cover ring 2 is rotatably connected to the outer wall of the pipe body 1, and a cavity 8 is opened inside the outer cover ring 2, and a through hole 505 is opened on the outer wall of the pipe body 1 corresponding to the cavity 8, and at the same time, the pipe body 1 is connected to the inner wall of the cavity 8 through the through hole 505, and the bottom of the circulation shell 3 is threadedly connected with an atomizing nozzle 9, and the atomizing nozzle 9 is connected to the inner wall of the cavity 8 through the circulation shell 3, so that the water can pass through the through hole 505 into the cavity 8, and then the water is atomized and sprayed out through the atomizing nozzle 9 at the bottom of the circulation shell 3, so as to realize spray dust reduction;

[0036] Then, during the spraying process, the driving disc 502 is fixedly connected to the output shaft at one end of the driving motor 501, and the outer wall of the driving disc 502 is fixedly connected to the collision columns 503 at equal distances, and the outer cover ring 2 is fixedly connected to the collision columns 503 at equal distances at one end surface facing the driving motor 501, so that the driving motor 501 can drive several collision columns 503 on the outer wall of the driving disc 502 to move in a circle and contact and collide with the fixed columns 504, so that when the driving disc 502 rotates forward and reverse, the outer cover ring 2 can be synchronously driven to rotate forward and reverse at a certain angle, so that the atomizing nozzle 9 on the circulation shell 3 can swing and spray, and then a large-scale atomizing spray can be performed in the tunnel space, which is conducive to ensuring that the spray range covers the entire tunnel construction area;

[0037] As described above, when dust removal is performed, the driving motor 501 can drive the driving disk 502 to rotate forward and reverse at a certain angle, thereby driving the atomizing nozzle 9 on the circulation shell 3 to swing and spray, and then a large-scale atomizing spray can be performed in the tunnel space, which is beneficial to ensure that the spray range covers the entire tunnel construction area, so as to effectively control the dust on the construction site, reduce the impact of dust on the health of construction workers, and at the same time reduce the wear of dust on mechanical equipment and improve construction efficiency.

[0038] Embodiment 2: Based on the above embodiment, a measurement auxiliary mechanism 6 is provided on the outer wall of the tube body 1 .

[0039] Further, the measurement auxiliary mechanism 6 includes a dust detector 601, and one side of the dust detector 601 is fixedly installed on the outer wall of the cylinder 4, a fan 602 is fixedly installed on the top of the cylinder 4 corresponding to the dust detector 601, and a filter plate 10 is arranged inside the cylinder 4 corresponding to the fan 602, a mounting shell 603 is fixedly connected to the outer wall of the tube body 1, and an adsorption column 604 is fixedly installed inside the mounting shell 603, and a coil 605 is installed on the outer wall of the adsorption column 604, and a support frame 606 is arranged on the outer wall of the tube body 1 corresponding to the drive motor 501, and one end of the drive motor 501 is fixedly installed on a side wall of the support frame 606;

[0040] In this embodiment, first, one side of the dust detector 601 is fixedly installed on the outer wall of the cylinder 4, and the top of the cylinder 4 is fixedly installed with a fan 602 corresponding to the dust detector 601, and the inside of the cylinder 4 is provided with a filter disc 10 corresponding to the fan 602, so that the fan 602 can generate suction at the bottom opening of the cylinder 4 to suck in external dust, and then the dust detector 601 can sense and detect the dust flowing through the inner wall of the cylinder 4, and the filter disc 10 can be used to block and filter the dust to avoid damage to the fan 602;

[0041] Then, during the detection process, the cylinder 4 is fixedly connected to the circulation shell 3, so that when the circulation shell 3 is swayed, the bottom direction of the cylinder 4 is synchronously changed to detect the dust content in different directions. Then, the outer wall of the tube body 1 is fixedly connected with the mounting shell 603, and the interior of the mounting shell 603 is fixedly installed with an adsorption column 604, and the outer wall of the adsorption column 604 is installed with a coil 605. At the same time, the outer wall of the tube body 1 is provided with a support frame 606 corresponding to the driving motor 501, and one end of the driving motor 501 is fixedly installed on a side wall of the support frame 606, so that during the detection process, the dust detector 601 can be used to control the adsorption column 604. 04 cooperates with the coil 605 to generate a magnetic force to adsorb the support frame 606. At this time, a connecting rod 607 is fixedly connected to the top of the support frame 606, and a rubber block 608 is fixedly connected to the bottom of the other end of the connecting rod 607, and a side wall of the rubber block 608 fits with one end face of the outer cover ring 2, so that the rubber block 608 can be squeezed with one end face of the outer cover ring 2 through the suction force of the adsorption column 604. Furthermore, the dust content detected by the dust detector 601 is proportional to the current intensity of the coil 605, that is, the higher the dust content, the greater the adsorption intensity of the adsorption column 604, so that the rubber block 608 has a stronger extrusion force on the outer cover ring 2;

[0042] Next, on the basis of the above, the plurality of fixed columns 504 are all made of the same hard material, while the plurality of collision columns 503 are all made of flexible material, and the hardness of each collision column 503 is different, so that when the dust content is low, the adsorption force of the adsorption column 604 is small, so that the extrusion force of the rubber block 608 on the outer cover ring 2 is small, and when the plurality of collision columns 503 contact and collide with the fixed column 504, most of the collision columns 503 can successfully drive the fixed column 504 to move, that is, the outer cover ring 2 rotates faster at this time, and when the dust content is high, at this time The adsorption force of the adsorption column 604 is relatively large, so that the rubber block 608 has a relatively large extrusion force on the outer cover ring 2. At this time, when a plurality of collision columns 503 contact and collide with the fixed column 504, only a small number of collision columns 503 can successfully drive the fixed column 504 to move, so that the rotation speed of the outer cover ring 2 is relatively slow, so that when the directions of dust with different contents are detected, the swing rate of the circulation shell 3 can be slowed down, and then the atomization spray can be performed for a longer time for the directions of dust with different contents, so that the water mist can better contact and mix with the dust with higher content;

[0043] Then, a slider 609 is fixedly connected to the bottom of the support frame 606, and a slide groove 16 is opened on the outer wall of the tube body 1 corresponding to the slider 609, and the outer wall of the slider 609 slides in contact with the inner wall of the slide groove 16, and at the same time, a first spring 610 is fixedly connected to one end of the slider 609 facing the adsorption column 604, and the other end of the first spring 610 is fixed to the inner wall of the slide groove 16. Further, the slider 609 is T-shaped, that is, the slider 609 can only slide in the slide groove 16 and cannot be taken out, thereby ensuring the stability of the support frame 606 during movement, and at the end of adsorption, the first spring 610 can be used to drive the support frame 606 to reset;

[0044] By doing as above, during dust removal, the fan 602 and the dust detector 601 can be used to detect the dust content in different directions when the circulation shell 3 is swinging and moving, and the adsorption column 604 and the rubber block 608 cooperate to slow down the swinging rate of the circulation shell 3 when the directions of dust contents of different contents are detected, so that atomization spraying can be performed for a longer time in the directions of dust contents of different contents, so that the water mist can better contact and mix with the dust with higher content, which is beneficial to improve the dust reduction effect of the present equipment.

[0045] Embodiment 3: Based on the above embodiment, a flow auxiliary mechanism 7 is provided on the inner wall of the cylinder 4 .

[0046] Further, the flow auxiliary mechanism 7 includes a rotating rod 701, and the outer wall of the rotating rod 701 is rotatably connected to the inner center of the filter disc 10, the outer wall of one end of the rotating rod 701 facing the fan 602 is fixedly connected with a wind turbine blade 702, and the outer wall of one end of the rotating rod 701 away from the fan 602 is symmetrically fixedly connected with a scraper rod 703, the upper surfaces of the two scraper rods 703 are fitted and slid with the bottom surface of the filter disc 10, the inner wall of the cylinder 4 is provided with a movable groove 11 corresponding to the filter disc 10, and the outer wall of the filter disc 10 is fitted and slid with the inner wall of the movable groove 11;

[0047] In this embodiment, when dust removal is performed, the outer wall of the rotating rod 701 is rotatably connected to the inner center of the filter disc 10, and the outer wall of one end of the rotating rod 701 facing the fan 602 is fixedly connected with a wind turbine blade 702, and the outer wall of one end of the rotating rod 701 away from the fan 602 is symmetrically fixedly connected with a scraper rod 703, and at the same time, the upper surfaces of the two scraper rods 703 are fitted and slid with the bottom surface of the filter disc 10, so that the wind force passing through the filter disc 10 can be used to drive the wind turbine blade 702 to rotate, and then synchronously drive the two scraper rods 703 to continuously clean the surface of the filter disc 10, so as to avoid affecting the detection accuracy of the dust detector 601;

[0048] Then, on the basis of the above, a movable groove 11 is opened through the inner wall of the cylinder 4 corresponding to the filter disc 10, and the outer wall of the filter disc 10 slides in contact with the inner wall of the movable groove 11, so that when the cleaning effect of the scraper 703 on the filter disc 10 cannot keep up with the rate of dust coverage, at this time, as several filter holes of the filter disc 10 are blocked, the air flow rate increases, driving the filter disc 10 to rise, and then a slide bar 705 is fixedly connected to the top surface of the filter disc 10, and a through groove 12 is opened through the top of the cylinder 4 corresponding to the slide bar 705, and the outer wall of the slide bar 705 slides in contact with the inner wall of the through groove 12, so that the slide bar 705 can be driven by the filter disc 10 The shaft 706 is connected to the fan 602 through the circulation housing 3, and the first gear 707 is fixedly connected to the outer wall of one end of the shaft 706 facing the fan 602, and one side of the first gear 707 is meshed with the top outer wall of the slide bar 705. At the same time, the second gear 708 is fixedly connected to the outer wall of the end of the shaft 706 away from the fan 602, and the rack 709 is meshed on one side of the second gear 708, so that the first gear 707 can be synchronously driven to rotate when the slide bar 705 rises, and then the second gear 708 can drive the rack 709 to descend through the shaft 706;

[0049] Then, a support rod 710 is fixedly connected to the top of the rack 709, and a sealing plugging column 711 is fixedly connected to the top of the support rod 710, and a flow control plate 13 is fixedly connected to the inner wall of the flow shell 3, and a flow hole 14 is penetrated and opened in the inner center of the flow control plate 13 corresponding to the sealing plugging column 711, and at the same time, the outer wall of the sealing plugging column 711 fits and slides with the inner wall of the flow hole 14, and the top of the sealing plugging column 711 is truncated. Therefore, when the rack 709 is lowered, the sealing plugging column 711 can be driven to lower through the support rod 710, so that the flow rate of water from the flow hole 14 is increased, and then the injection flow rate can be increased. Similarly, after increasing the flow rate and reducing the dust content, the cleaning effect of the scraper rod 703 on the filter disc 10 will catch up with the covering rate, so that the filter disc 10 returns to its original position under the elastic force of the second spring 704, so that the water flow rate returns to a normal value, so as to achieve the effect of saving water resources;

[0050] By doing as above, during dust removal, the circulating wind can synchronously drive the wind turbine blades 702 to rotate, so that the surface of the filter disc 10 can be cleaned in time by the scraper rod 703, avoiding affecting the detection accuracy of the dust detector 601, which is beneficial to improving the accuracy during precise injection. When the dust content is too high and the filter disc 10 is still blocked, the rise of the filter disc 10 can be used to drive the sealing column 711 to descend, so that the injection flow rate can be synchronously increased as the dust increases, and the injection flow rate can be synchronously reduced when the dust content decreases, so as to achieve the effect of saving water resources.

[0051] Working principle: First, open the valve of the pipe body 1 to allow water to flow and transport in the pipe body 1, so that the water passes through the through hole 505 and enters the cavity 8, and then the water is atomized and sprayed out through the atomizing nozzle 9 at the bottom of the circulation shell 3 to achieve spray dust reduction;

[0052] Then, during the spraying process, the driving motor 501 drives several collision columns 503 on the outer wall of the driving disk 502 to move in a circle and contact and collide with the fixed column 504, so that when the driving disk 502 rotates forward and reverse, the outer cover ring 2 can be synchronously driven to rotate forward and reverse at a certain angle, so that the atomizing nozzle 9 on the flow shell 3 can swing and spray, and then a large-scale atomizing spray can be performed in the tunnel space;

[0053] Then, during the detection process, the cylinder 4 is fixedly connected to the circulation shell 3, so that when the circulation shell 3 is swaying, the bottom direction of the cylinder 4 is synchronously changed to detect the dust content in different directions. During the detection process, the dust detector 601 can control the magnetic force generated by the adsorption column 604 and the coil 605 to adsorb the support frame 606, so that the rubber block 608 is squeezed with one end surface of the outer cover ring 2;

[0054] When the dust content is low, the adsorption force of the adsorption column 604 is small, so that the extrusion force of the rubber block 608 on the outer cover ring 2 is small. At this time, when a plurality of collision columns 503 contact and collide with the fixed column 504, most of the collision columns 503 can successfully drive the fixed column 504 to move, that is, the rotation speed of the outer cover ring 2 is fast at this time. When the dust content is high, the adsorption force of the adsorption column 604 is large, so that the extrusion force of the rubber block 608 on the outer cover ring 2 is large. At this time, when a plurality of collision columns 503 contact and collide with the fixed column 504, only a small number of collision columns 503 can successfully drive the fixed column 504 to move, so that the rotation speed of the outer cover ring 2 is slow, so that when the directions of dust with different contents are detected, the swing rate of the circulation shell 3 can be slowed down;

[0055] Then, when dust removal is performed, the wind force passing through the filter disc 10 can be used to drive the wind turbine blades 702 to rotate, thereby synchronously driving the two scraper rods 703 to continuously clean the surface of the filter disc 10, thereby avoiding affecting the detection accuracy of the dust detector 601;

[0056] Then, when the cleaning effect of the scraper rod 703 on the filter disc 10 cannot keep up with the rate of dust coverage, at this time, as several filter holes of the filter disc 10 are blocked, the air flow rate increases, driving the filter disc 10 to rise, so that the filter disc 10 can drive the slide bar 705 to rise, and when the slide bar 705 rises, it can synchronously drive the first gear 707 to rotate, and then through the shaft rod 706, the second gear 708 can drive the rack 709 to descend, so that when the rack 709 descends, the support rod 710 can drive the sealing plug 711 to descend, so that the flow of water from the flow hole 14 increases, and then the injection flow can be increased;

[0057] Similarly, after increasing the flow rate and reducing the dust content, the cleaning effect of the scraper rod 703 on the filter disc 10 will catch up with the covering rate, so that the filter disc 10 returns to its original position under the elastic force of the second spring 704, and the water flow returns to normal, thereby achieving the effect of saving water resources.

[0058] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
