[0002] The subway is a form of railway transportation, referring to an urban rail transit system mainly operating underground, namely the abbreviation of "subway" or "underground railway". In order to match the construction environment and consider the construction and operation costs, many such systems may turn into ground or elevated sections outside the city center. The subway is an urban rail transit system that covers various underground and above-ground exclusive rights of way, high density, and high traffic volume in urban areas. During the construction process of the subway underground, a large amount of dust will be generated, which will affect the health of construction workers. For this reason, the prior art provides dust removal devices.

[0003] In the existing atomizing dust reduction device for subway construction dust removal, during use, due to different construction locations and construction conditions, the amount of dust generated and its distribution are also different. A single and quantitatively atomizing dust reduction device cannot meet the needs of the actual site and will cause waste of resources such as water resources, and it is more inconvenient to use. Therefore, in view of the above current situation, there is an urgent need to develop an atomizing dust reduction device for subway construction dust removal to overcome the deficiencies in current practical applications.

Detailed implementation manners

[0045] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0046] The following describes the specific implementation of the present invention in detail in conjunction with specific embodiments.

[0047] Please refer to Figures 1-5 , a fogging dust reduction device for subway construction dust removal provided by an embodiment of the present invention includes a base 1, and further includes:

[0048] A support cylinder 4, the support cylinder 4 is rotatably installed on the base 1, and a water tank 7 is fixedly installed on the top of the support cylinder 4;

[0049] A lifting and recycling ring box 5, the lifting and recycling ring box 5 is sleeved on the support cylinder 4 and is slidably connected to the support cylinder 4, and the lifting and recycling ring box 5 is also communicated with the water tank 7 through a recycling telescopic pipe 6; and

[0050] A fogging dust reduction mechanism, the fogging dust reduction mechanism is respectively connected to the lifting and recycling ring box 5 and the water tank 7. Among them, the fogging dust reduction mechanism includes an atomizing dust removal plate 9, a dust reduction component, a recycling component and an adjusting component;

[0051] The adjusting component is respectively connected to the lifting and recycling ring box 5 and the water tank 7, an atomizing dust removal plate 9 is installed on the adjusting component, the dust reduction component is respectively connected to the water tank 7 and the atomizing dust removal plate 9, and the recycling component is respectively connected to the lifting and recycling ring box 5 and the atomizing dust removal plate 9.

[0052] When it is necessary to reduce dust at the subway construction site, first of all, through the set base 1, where the base 1 can be in the form of a steel framework, and the entire dust reduction device can be fixed in a designated area, such as an area with a large amount of dust generated, by means of bolt connection. Then, through the set lifting and recycling ring box 5 and water tank 7, where corresponding pumping equipment, valve parts and other components are provided in both the lifting and recycling ring box 5 and the water tank 7 to provide power for the clear water to circulate in the entire dust reduction device. This will not be elaborated here too much. And through the set recycling telescopic pipe 6, the clear water recycled in the lifting and recycling ring box 5 can flow back into the water tank 7 at a certain speed. Driven by the pumping equipment, the clear water in the water tank 7 first enters the atomizing dust removal plate 9, and the dust in the air is removed from dust through the set dust reduction components. The excess clear water then flows back into the lifting and recycling ring box 5 through the recycling components and finally flows back into the water tank 7 again through the recycling telescopic pipe 6. Under the normal working state of the equipment, the clear water is in a stable dynamic circulation process, and the overall weight of the lifting and recycling ring box 5 will not change significantly. When the amount of dust in the air is large, the amount of clear water introduced into the atomizing dust removal plate 9 will be increased accordingly. At this time, when the amount of clear water entering the lifting and recycling ring box 5 is greater than the discharge amount, the previous dynamic balance will be destroyed, and the increased clear water will drive the lifting and recycling ring box 5 to move downward on the support cylinder 4. During the downward movement of the lifting and recycling ring box 5, through the set adjustment components, where the adjustment components are located between the lifting and recycling ring box 5 and the water tank 7 and will move on the support cylinder 4 due to the change in the weight of the lifting and recycling ring box 5. When the lifting and recycling ring box 5 moves downward, the atomizing dust removal plate 9 will rotate by a certain angle, so that the spraying direction of the atomizing dust removal plate 9 can be adjusted. The operation is simple, and the water volume and spraying direction can be adjusted according to the actual amount of dust and the dust distribution situation, so as to meet the needs of the actual construction site, save resources, reduce the amount of dust, ensure the air quality of the construction environment, and provide convenience for the staff.

[0053] In an embodiment of the present invention, please refer to Figure 1 , and further includes: a driving motor 2, the driving motor 2 is fixedly installed on the base 1; and

[0054] a transmission member 3, the transmission member 3 is respectively connected to the driving motor 2 and the support cylinder 4.

[0055] Please refer to Figure 1 and Figure 5 , and further includes: a sleeve 27, the sleeve 27 is fixedly installed on the lifting and recycling ring box 5;

[0056] a telescopic rod 26, one end of the telescopic rod 26 is sleeved in the sleeve 27 and is slidably connected to the sleeve 27;

[0057] The support spring 28 is located within the sleeve 27, and both ends of the support spring 28 are fixedly connected to the telescopic rod 26 and the sleeve 27 respectively; and

[0058] A position control component, which is respectively connected to the support cylinder 4 and the telescopic rod 26.

[0059] Please refer to Figure 5 , the position control component includes:

[0060] An adjustment cylinder 22, which is fixedly installed on the support cylinder 4;

[0061] An adsorption piston plate 24, which is slidably installed within the adjustment cylinder 22, and the adsorption piston plate 24 is fixedly connected to the end of the telescopic rod 26; and

[0062] An electromagnet one 23 and an electromagnet two 25, both of which are fixedly installed within the adjustment cylinder 22, and both the electromagnet one 23 and the electromagnet two 25 are detachably connected to the adsorption piston plate 24.

[0063] During the operation of the dust reduction component, when the drive motor 2 is started, the support cylinder 4 can be driven to rotate on the base 1 under the transmission of the transmission member 3. Among them, the transmission member 3 can adopt a structure of meshing transmission between gears, and the support cylinder 4 is installed on the base 1 through a rotating base, so that the entire dust reduction device can be in slow rotation, increasing the contact area between the dust reduction device and the air, improving the dust reduction effect. At the same time, when the increase in the amount of clear water in the lifting and recycling ring box 5 becomes larger, the overall weight of the lifting and recycling ring box 5 increases accordingly. At this time, when the weight of the lifting and recycling ring box 5 overcomes the elastic force of the multiple support springs 28, the lifting and recycling ring box 5 will move downward to achieve the adjustment of the spraying direction. In addition, when it is necessary to adjust the spraying direction but not increase the water volume, at this time, the electromagnet one 23 and the electromagnet two 25 can be made to change the direction of the current passing through them, so that the electromagnet two 25 generates a magnetic repulsive force on the adsorption piston plate 24, while the electromagnet one 23 generates a magnetic attractive force on the adsorption piston plate 24. Under the combined action of the two forces, the adsorption piston plate 24 can be moved downward, and a part of the telescopic rod 26 can be extended into the adjustment cylinder 22, so as to artificially reduce the height of the lifting and recycling ring box 5 to achieve the purpose of adjusting the spraying direction. Among them, a magnet is fixedly installed on the surface of the adsorption piston plate 24 to cooperate with the electromagnet one 23 and the electromagnet two 25 for work.

[0064] In an embodiment of the present invention, please refer to Figure 1 and Figure 2 , the adjustment component includes:

[0065] The limiting groove plate 15 is fixedly installed on the lifting and recycling ring box 5;

[0066] The first support rod 13 and the second support rod 29, the first support rod 13 and the second support rod 29 are both fixedly installed on the water tank 7, and the second support rod 29 is clamped in the limiting groove plate 15 and is slidably connected with the limiting groove plate 15;

[0067] The dust removal frame 14 is rotatably connected to the first support rod 13 and the second support rod 29 respectively, and the dust removal frame 14 is also fixedly connected to the atomizing dust removal plate 9; and

[0068] The movable connecting rod 17, the two ends of the movable connecting rod 17 are respectively hinged to the lifting and recycling ring box 5 and the dust removal frame 14.

[0069] When the weight of the lifting and recycling ring box 5 increases, the lifting and recycling ring box 5 will move downward on the support cylinder 4. At the same time, under the guiding action of the clamping between the limiting groove plate 15 and the second support rod 29, it can ensure that the lifting and recycling ring box 5 moves vertically downward. At this time, the lifting and recycling ring box 5 can pull the dust removal frame 14 to rotate between the first support rod 13 and the second support rod 29 through the movable connecting rod 17, and the rotation direction is counterclockwise rotation, so as to change the spraying direction of the atomizing dust removal plate 9. In addition, under the action of the rotation of the dust removal frame 14, the contact area between the atomizing dust removal plate 9 and the air can be enlarged, thereby increasing the dust removal range and being beneficial to improving the dust removal effect.

[0070] In an embodiment of the present invention, please refer to Figure 1 、 Figure 3 and Figure 4 , the dust removal assembly includes:

[0071] The atomizer housing 12 is fixedly connected to the atomizing dust removal plate 9 and the dust removal frame 14 respectively, and the atomizer housing 12 is also fixedly connected to the water tank 7 through the second connecting hose 11;

[0072] The atomizing channel 20 is opened on the atomizing dust removal plate 9 and is communicated with the atomizer housing 12; and

[0073] The number of the spray heads 10 is multiple, the spray heads 10 are evenly distributed on the atomizing dust removal plate 9, and the multiple spray heads 10 are all communicated with the atomizing channel 20.

[0074] Please refer to Figure 1 and Figure 3, further comprising: a flow guide member 18, which is fixedly installed on the atomizer housing 12, communicates with the atomizer housing 12, and is installed on the side wall of the flow guide member 18 close to the atomization dust removal plate 9; and

[0075] spray holes 19, the number of the spray holes 19 is multiple, the multiple spray holes 19 are evenly distributed on the flow guide member 18, and the spray holes 19 are arranged facing the atomization dust removal plate 9.

[0076] Please refer to Figure 1 and Figure 4 , the recovery assembly includes:

[0077] a recovery filter tank 16, which is fixedly connected to the atomization dust removal plate 9 and the dust removal frame 14 respectively;

[0078] a connecting hose 8, the two ends of the connecting hose 8 are respectively connected to the lifting recovery ring box 5 and the recovery filter tank 16; and

[0079] a filter screen 21, which is laid between the atomization dust removal plate 9 and the recovery filter tank 16.

[0080] During the dust reduction process, under the pressure of the pumping equipment, the clear water in the water tank 7 can enter the atomizer housing 12 through the connecting hose 11. Among them, an atomizer and a bypass pipe are provided in the atomizer housing 12, and the clear water entering the atomizer housing 12 can be divided into two directions. One part of the clear water is atomized and is transported from the atomization channel 20 to a plurality of nozzles 10 for spraying to settle the dust in the air. The other part of the clear water will enter the flow guide member 18 through the bypass pipe and spray out from the spray holes 19. The flow guide member 18 can be in the form of a hollow triangular prism. Since the flow guide member 18 is installed close to the atomization dust removal plate 9, a flowing water film can be formed on the side wall of the atomization dust removal plate 9. Therefore, during the rotation of the atomization dust removal plate 9, because the equipment is in an area with a large amount of dust, the dust in the air close to the equipment can be adsorbed, and the dust is washed into the recovery filter tank 16 for collection, which is beneficial to further improving the dust reduction effect. When the excess clear water flows back into the recovery filter tank 16, the dust will be filtered on the filter screen 21, and the filtered clear water will flow back into the lifting recovery ring box 5 through the connecting hose 8 and be reused again, avoiding the waste of water source.

[0081] It should be noted that in the present invention, unless otherwise clearly defined and limited, terms such as "sliding", "rotating", "fixing", "provided with", etc. should be understood in a broad sense. For example, it can be a welded connection, a bolt connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0082] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution.
