Description

Technical Field

[0001] This invention relates to the field of dust suppression technology, specifically to a dust suppression spraying device for water conservancy projects. Background Technology

[0002] Water conservancy engineering dust suppression spraying devices are environmental protection equipment used in water conservancy engineering construction. They are mainly used in high-dust-generating operations such as earthwork excavation, sand and gravel screening and processing, and concrete mixing plants. The device atomizes water into fine droplets through an atomizing mechanism, and then uses a power conveying component to deliver the atomized droplets to the dust-generating area. The collision and adsorption between the droplets and dust particles cause the dust to agglomerate and settle, making the dust particles heavier and settling more easily. This effectively controls the dust concentration at the construction site. The delivery distance and coverage of the atomized droplets directly determine the efficiency and effectiveness of dust control.

[0003] Current dust suppression spraying devices for water conservancy projects use fans to generate airflow to transport atomized droplets. While this can extend the droplet transport distance, the atomized droplets tend to agglomerate into large particles during transport. The atomization coverage cannot be flexibly adjusted, making it difficult to dynamically adapt the dust suppression intensity according to the dust concentration and diffusion range at the construction site. This results in incomplete dust suppression in some areas, thus affecting the dust suppression effect.

[0004] To address the above problems, a dust suppression spraying device for water conservancy projects is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a dust suppression spraying device for water conservancy projects. By using this invention, the problem in the background is solved: when using a dust suppression spraying device for water conservancy projects, although the airflow generated by the fan can extend the droplet delivery distance, the atomized droplets easily agglomerate into large particles during delivery, making it difficult to flexibly adjust the atomization coverage area and dynamically adapt the dust suppression intensity according to the dust concentration and diffusion range at the construction site, resulting in incomplete dust suppression in some areas and thus affecting the dust suppression effect.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A dust suppression spraying device for water conservancy projects includes a mobile frame.

A water pumping component is mounted inside the mobile frame. An atomizing rotating component is rotatably mounted inside the telescopic component. A pulse component is mounted inside the airflow conveying component.

[0007] Furthermore, the rotating assembly includes a rotating seat rotatably connected to the top of the movable frame, and two V-shaped bearing plates are fixedly connected to the top of the rotating seat, with mounting sleeves fixedly connected to one end of each V-shaped bearing plate.

[0008] Furthermore, the airflow conveying assembly includes a fixed cylinder fixedly connected to the mounting sleeve, a mounting frame fixedly connected to one end of the fixed cylinder, an electric fan mounted on one side of the mounting frame, and the electric fan being disposed inside the fixed cylinder.

[0009] Furthermore, the telescopic assembly includes a first connecting ring fixedly connected to the outer wall of the fixed cylinder. Two electric push rods are installed opposite each other on one side of the first connecting ring. The movable ends of the two electric push rods are fixedly connected to a second connecting ring. A sliding cylinder is fixedly connected to the inner wall of the second connecting ring. Two sliding rods are fixedly connected opposite each other on one side of the second connecting ring. Both sliding rods are slidably connected to the first connecting ring. An annular frame is fixedly connected to one end of the sliding cylinder. The inner wall of the sliding cylinder is slidably connected to the outer wall of the fixed cylinder.

[0010] Furthermore, one end of the sliding cylinder is set to be tapered.

[0011] Furthermore, the limiting component includes several fixed rods fixedly connected to one side of the first connecting ring, and the other end of the several fixed rods is fixedly connected to a limiting ring. Several limiting rods are evenly fixedly connected to one side of the limiting ring, and each of the several limiting rods has a through groove.

[0012] Furthermore, the pump assembly includes a water tank fixedly connected to the movable frame, a support frame fixedly connected to the top of the water tank, a centrifugal pump installed on the top of the support frame, an inlet pipe connected to the inlet of the centrifugal pump and connected to the water tank, and a flexible hose connected to the outlet of the centrifugal pump and connected to the annular frame.

[0013] Furthermore, the atomizing rotating assembly includes several fixed shafts fixedly connected within the annular frame. Atomizing nozzles are rotatably connected to the outer walls of each fixed shaft. Several through holes are opened through one side of the annular frame. A connecting rod is fixedly connected to one end of each atomizing nozzle. Several water inlet slots are opened through the connecting rod. A rotating shaft is rotatably connected to one end of the connecting rod. A lifting rod is fixedly connected to the outer wall of the rotating shaft. Several lifting rods are slidably connected to the annular frame. An arc-shaped fixing sleeve is fixedly connected to one end of each lifting rod. Arc-shaped sliding rods are slidably connected to both sides of the arc-shaped fixing sleeve. Several arc-shaped sliding rods are slidably connected to several inclined slots respectively.

[0014] Furthermore, a number of conical corrugated pipes are fixedly connected to one side of the annular frame, and the other end of the conical corrugated pipes is fixedly connected to the outer wall of the atomizing nozzle, with the positions of the conical corrugated pipes corresponding to the through holes.

[0015] Furthermore, the pulse assembly includes a first conical ring and a second conical ring fixedly connected to the inner wall of the fixed cylinder. An electromagnetic ring is installed inside the first conical ring, and a magnetic ring is installed inside the second conical ring. The electromagnetic ring and the magnetic ring are coaxially arranged. An installation ring is fixedly connected to the inner wall of the fixed cylinder. Several moving rods are slidably connected inside the installation ring. One end of each of the moving rods is fixedly connected to the second conical ring. A spring is fixedly connected to one side of the installation ring, and the other end of each of the springs is fixedly connected to the moving rod. The springs are sleeved on the outer wall of the moving rod.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: By coordinating the telescopic component and the atomizing rotating component, the telescopic component can drive the atomizing rotating component to move when it retracts, causing the atomizing nozzle to rotate outward, thereby achieving a geometric expansion of the atomization coverage area and an increase in the atomization delivery distance. Through the cooperation between the limiting component and the atomizing rotation component, the arc-shaped slide bar of the atomizing rotation component can be provided with inclined groove limiting guidance, so that multiple atomizing nozzles can rotate evenly and synchronously, avoiding mechanical interference when the nozzles rotate, ensuring smooth adjustment, and allowing the atomization coverage area to expand in a regular shape; Through the cooperation between the airflow conveying component and the telescopic component, the conical sliding cylinder of the telescopic component can gather the high-speed airflow generated by the airflow conveying component, increase the airflow outlet velocity to enhance the pushing force on the atomized droplets, reduce the energy loss of the airflow along the way, and further improve the atomization conveying distance and dust suppression accuracy. By combining the pulse component and the airflow delivery component, a high-intensity pulsed air wave can be generated to perform secondary shearing on the atomized droplets, making their particle size smaller. At the same time, the disturbed airflow expands the droplet diffusion range, improving the adsorption and capture effect of fine particulate dust, and adapting to the dust suppression needs of dust with different particle sizes. By coordinating the telescopic components, atomizing rotation components, and pulse components, it is possible to simultaneously increase the atomization coverage and conveying distance, as well as precisely refine the atomized droplet size. This leverages the synergistic effect of telescopic linkage and pulse shearing, adapting to complex dust conditions and maximizing dust suppression efficiency. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] To address the technical problem of dust suppression spraying devices in water conservancy projects, which use fans to generate airflow to transport atomized droplets, although this can extend the droplet delivery distance, the atomized droplets easily agglomerate into large particles during transportation. This makes it difficult to flexibly adjust the atomization coverage area and dynamically adapt the dust suppression intensity according to the dust concentration and diffusion range at the construction site, resulting in incomplete dust suppression in some areas and thus affecting the overall dust suppression effect. Figures 1-8 As shown, the following preferred technical solutions are provided: like Figure 1As shown, a dust suppression spraying device for water conservancy projects includes a mobile frame 1. The mobile frame 1 can support and fix various components, while facilitating the movement of the device, enabling flexible movement and stable placement of the device in different construction areas of the water conservancy project. A controller is installed on one side of the mobile frame 1, which can control various electrical components. The controller is existing technology and is not shown in the figure. A rotating component 2 is rotatably installed on the top of the mobile frame 1. The rotating component 2 can drive the dust suppression device installed on its top to rotate, realizing the angle adjustment of the dust suppression device and expanding the dust suppression coverage area. An airflow conveying component 3 is installed inside the rotating component 2. The airflow conveying component 3 can generate and directionally convey high-speed airflow, providing the power basis for the subsequent conveying of atomized droplets. A telescopic component 4 is slidably installed on the outer wall of the airflow conveying component 3. A limit component 5 is installed on one side of the telescopic component 4. A water pumping component 6 is installed inside the mobile frame 1. Figure 5 As shown, an atomizing rotating component 7 is rotatably installed inside the telescopic component 4. The water pumping component 6 can draw water from the source and pressurize it to be delivered to the atomizing rotating component 7. The water is then atomized and sprayed out by the atomizing rotating component 7, thereby meeting the liquid pressure and flow rate required for atomization. The airflow channel of the dust suppression device is shortened by the contraction of the telescopic component 4. During the contraction of the telescopic component 4, the atomizing rotating component 7 can rotate inside the telescopic component 4, thereby increasing the atomization distance and expanding the atomization coverage area, thus enhancing the dust suppression effect.

[0021] In use, the user moves the dust suppression device to the location where dust needs to be suppressed by pushing the mobile frame 1. Then, the controller causes the airflow delivery component 3 to generate a high-speed airflow, and the water pump component 6 pumps out the water required for atomization. The water is then atomized and sprayed out by the atomizing rotation component 7, which effectively adsorbs and settles the dust in the water conservancy construction area, completing the basic dust suppression operation. When the dust suppression angle needs to be adjusted slightly during the dust suppression process, the user rotates the rotation component 2 to make it rotate on the mobile frame 1, thereby flexibly adapting to small-range changes in the direction of dust diffusion and improving the accuracy and flexibility of dust suppression.

[0022] Scenario 1: Based on the dust suppression requirements of the water conservancy project construction area, if it is necessary to expand the dust suppression coverage area or increase the delivery distance of the atomized droplets, the telescopic component 4 is retracted to the position corresponding to the dust suppression requirements by using the control program of the controller operated by the user. This position can be adaptively preset by the controller. At the same time, during the retraction of the telescopic component 4, the atomizing rotating component 7 will move synchronously. During the movement of the atomizing rotating component 7, through the limiting guide of the limiting component 5, the atomizing rotating component 7 can gradually rotate to a position away from the axis of the telescopic component 4, thereby achieving a geometric expansion of the atomization coverage area and an increase in the atomization delivery distance. This is suitable for dust control needs of large areas and long distances. Compared with the existing technology that requires manual adjustment of the nozzle angle and airflow channel length and has low adjustment efficiency and poor adaptability, the telescopic component 4 and the atomizing rotating component 7 can achieve adaptive adjustment through linkage, improving the efficiency and automation of dust suppression operations, while ensuring the stability of the dust suppression effect after adjustment.

[0023] like Figure 7 As shown, the airflow delivery component 3 is equipped with a pulse component 8, which can generate pulsed air waves to shear atomized droplets to make their particle size smaller, and the air wave frequency can be adjusted to adapt to different atomization requirements.

[0024] Scenario 2: Based on the dust suppression requirements of the water conservancy project construction area, if it is necessary to improve the adsorption and capture effect of fine particulate dust, the user operates the controller program to energize the attraction structure within the pulse assembly 8, gradually attracting the driven structure within the pulse assembly 8 and compressing the elastic structure within the pulse assembly 8. When the driven structure within the pulse assembly 8 moves to fit against one side of the attraction structure within the pulse assembly 8, the controller de-energizes the attraction structure within the pulse assembly 8, causing the attraction structure within the pulse assembly 8 to release its attraction to the driven structure within the pulse assembly 8, and the elastic structure within the pulse assembly 8... The reset mechanism drives the driven structure within the pulse assembly 8 to reset rapidly. During the reset process, the airflow within the air delivery assembly 3 is rapidly compressed, forming a high-intensity pulsed air wave. This wave performs secondary shearing on the atomized droplets, making their particle size smaller. Simultaneously, the disturbed airflow further expands the droplet diffusion range. Compared to existing technologies where the atomized droplet size is relatively coarse, the adsorption capacity for fine dust particles is limited, and the atomization effect is fixed and cannot be dynamically adjusted, this technology can achieve precise refinement of the atomized droplet size and flexible control of the atomization effect, improving the efficiency of fine dust treatment and adapting to the dust suppression needs of different particle sizes.

[0025] Simultaneously, the controller can adjust the frequency and speed of the attracted structure within the pulse component 8 to attract the driven structure within the pulse component 8. This frequency and speed can be adaptively preset by the controller, thereby achieving the regulation of the frequency and speed of pulsed air wave generation. It can match different dust concentrations and dust particle sizes as needed, and flexibly adjust the fineness and diffusion effect of the atomized droplets according to the real-time changes in dust at the construction site, further enhancing the intelligent adaptability of the device, while avoiding unnecessary energy and water consumption, and balancing dust reduction efficiency and economic efficiency.

[0026] Scenario 3: When Scenario 1 and Scenario 2 are used in combination, the atomization coverage and conveying distance can be improved at the same time, and the atomized droplet particle size can be precisely refined. This forms a comprehensive and refined synergistic treatment of dust. Compared with the existing technology, which cannot simultaneously take into account the problems of large-scale long-distance dust suppression and fine particulate dust capture, and the independent adjustment and poor adaptability of each dust suppression function, this technology can give full play to the synergistic effect of telescopic linkage and pulse shearing, improve the device's adaptability to the complex dust conditions at water conservancy construction sites, and maximize the dust suppression effect.

[0027] The rotating assembly 2 includes a rotating seat 21 rotatably connected to the top of the movable frame 1. A snap-fit ​​structure is provided on one side of the rotating seat 21, which can fix the rotating seat 21 and thus achieve convenient fixation of the dust removal angle. At the same time, the snap-fit ​​structure is existing technology and is not shown in the figure. Two V-shaped bearing plates 22 are fixedly connected to the top of the rotating seat 21, and an installation sleeve 23 is fixedly connected to one end of the two V-shaped bearing plates 22.

[0028] like Figure 2 and Figure 7 As shown, the airflow conveying assembly 3 includes a fixed cylinder 31 fixedly connected to the mounting sleeve 23. One end of the fixed cylinder 31 is fixedly connected to the mounting frame 32. An electric fan 33 is installed on one side of the mounting frame 32. The electric fan 33 is located inside the fixed cylinder 31.

[0029] The telescopic assembly 4 includes a first connecting ring 41 fixedly connected to the outer wall of the fixed cylinder 31. Two electric push rods 42 are installed opposite each other on one side of the first connecting ring 41. The movable ends of the two electric push rods 42 are fixedly connected to a second connecting ring 43. A sliding cylinder 45 is fixedly connected to the inner wall of the second connecting ring 43. Two sliding rods 44 are fixedly connected opposite each other on one side of the second connecting ring 43. Both sliding rods 44 are slidably connected to the first connecting ring 41. An annular frame 46 is fixedly connected to one end of the sliding cylinder 45. The inner wall of the sliding cylinder 45 is slidably connected to the outer wall of the fixed cylinder 31. A sealing ring is provided inside the sliding cylinder 45 to seal the sliding connection between the inner wall of the sliding cylinder 45 and the outer wall of the fixed cylinder 31, preventing high-speed airflow from leaking through the gap, ensuring concentrated airflow delivery to maintain sufficient pushing force, and ensuring stable dust suppression effect.

[0030] like Figure 3 As shown, one end of the sliding cylinder 45 is set as a cone, which can gather the high-speed airflow conveyed by the airflow conveying component 3, increase the airflow outlet velocity to enhance the pushing force on the atomized droplets, and guide the airflow to more concentratedly carry the droplets for diffusion, reduce the energy loss of the airflow along the way, and further improve the atomization conveying distance and dust reduction accuracy.

[0031] like Figures 2-4 , Figure 6 and Figure 7 As shown, the limiting component 5 includes several fixed rods 51 fixedly connected to one side of the first connecting ring 41, and the other end of the several fixed rods 51 is fixedly connected to a limiting ring 52. Several limiting rods 53 are evenly fixedly connected to one side of the limiting ring 52, and the several limiting rods 53 are all provided with inclined grooves 54.

[0032] like Figure 1 and Figure 2 As shown, the water pump assembly 6 includes a water tank 61 fixedly connected to the movable frame 1. A support frame 62 is fixedly connected to the top of the water tank 61. A centrifugal pump 63 is installed on the top of the support frame 62. The inlet of the centrifugal pump 63 is connected to an inlet pipe 65, which is connected to the water tank 61. One end of the inlet pipe 65 extends to the bottom of the inner wall of the water tank 61. The outlet of the centrifugal pump 63 is connected to a flexible hose 64. The flexible hose 64 is made of high-strength polyurethane or nylon reinforced material, which can reduce the occurrence of bending. It also has high pressure resistance, corrosion resistance and good elasticity and flexibility, adapting to the dynamic movement of the telescopic assembly 4, and avoiding damage and leakage of the flexible hose 64 due to the extension or movement of the device. The flexible hose 64 is connected to the annular frame 46.

[0033] like Figure 5 and Figure 6 As shown, the atomizing rotation assembly 7 includes several fixed shafts 71 fixedly connected within the annular frame 46. Atomizing nozzles 72 are rotatably connected to the outer walls of each fixed shaft 71. Several through holes are formed on one side of the annular frame 46. The diameter of the atomizing nozzles 72 is smaller than the diameter of the through holes, providing sufficient space for the rotation of the atomizing nozzles 72. A connecting rod 73 is fixedly connected to one end of each atomizing nozzle 72. Several water inlet grooves 74 are formed through the connecting rod 73, allowing the water inlet grooves 74 to... The high-pressure water source inside the annular frame 46 is stably delivered to the atomizing nozzle 72 to achieve continuous water supply. At the same time, it is adapted to the rotation of the atomizing nozzle 72 and will not cause the water supply to be interrupted due to the rotation of the nozzle. One end of the connecting rod 73 is rotatably connected to the rotating shaft 75. The outer wall of the rotating shaft 75 is fixedly connected to the lifting rod 76. Several lifting rods 76 are slidably connected to the annular frame 46. A sealing ring is provided on the inner wall of the annular frame 46 to prevent water from leaking through the connection between the annular frame 46 and the lifting rod 76.

[0034] Several lifting rods 76 are each fixedly connected to an arc-shaped fixing sleeve 77 at one end. Arc-shaped sliding rods 78 are slidably connected to both sides of the arc-shaped fixing sleeves 77, accommodating changes in the diameter of the ring formed by the arc-shaped fixing sleeves 77 and the arc-shaped sliding rods 78. This also adapts to the sliding trajectory of the arc-shaped sliding rods 78 within the inclined grooves 54, preventing jamming during linkage and ensuring smooth adjustment of the atomizing rotating assembly 7. Several arc-shaped sliding rods 78 are slidably connected to several inclined grooves 54 respectively. The arc-shaped fixing sleeves 77 and the arc-shaped sliding rods 78 form a ring, enabling... Several lifting rods 76 slide synchronously along the inclined grooves 54 of the limiting rods 53, driving several atomizing nozzles 72 to rotate evenly and synchronously, ensuring that the atomization coverage area expands in a regular shape, while improving the overall stability and linkage coordination of the atomizing rotation assembly 7. Several limiting rods 53 are arranged in an array to form a circle, which is adapted to the annular layout of the atomizing rotation assembly 7, providing full circumferential and uniform limiting guidance for the sliding of several arc-shaped sliding rods 78, ensuring that when the telescopic assembly 4 moves, all atomizing nozzles 72 rotate synchronously and evenly in the circumferential direction.

[0035] The staggered arrangement of several limiting rods 53 and several atomizing nozzles 72 can prevent mechanical interference between the atomizing nozzles 72 and the limiting rods 53 when the atomizing nozzles 72 rotate to adjust their angle, ensuring smooth rotation of the nozzles. At the same time, it does not affect the limiting rods 53's limiting and guiding of the arc-shaped slide bar 78, ensuring the linkage stability between the atomizing rotation assembly 7 and the limiting assembly 5.

[0036] Several conical corrugated tubes 9 are fixedly connected to one side of the annular frame 46, and the other end of the conical corrugated tubes 9 is fixedly connected to the outer wall of the atomizing nozzle 72. The conical corrugated tubes 9 correspond to the positions of the through holes. The conical corrugated tubes 9 are made of aging-resistant rubber or silicone-reinforced material, which can adapt to the rotation of the atomizing nozzle 72, and have good rigidity and elasticity. The connection is equipped with a sealing structure to prevent water from seeping out from the connection between the atomizing nozzle 72 and the annular frame 46. The other end of several conical corrugated tubes 9 is fixedly connected to one side of the annular frame 46.

[0037] In use, the user moves the dust suppression device to the location where dust needs to be suppressed by pushing the mobile frame 1. Then, the controller rotates the electric fan 33, which generates a high-speed airflow. The high-speed airflow passes through the fixed cylinder 31 into the sliding cylinder 45 and is discharged. The centrifugal pump 63 draws water from the water tank 61 through the water inlet pipe 65, and through the hose 64 into the annular frame 46. The water is then atomized and sprayed out by the atomizing nozzle 72, effectively adsorbing and settling the dust in the water conservancy construction area, thus completing the basic dust suppression operation. When the dust suppression angle needs to be adjusted slightly during the dust suppression process, the user pushes and pulls the two V-shaped bearing plates 22 to rotate the rotating seat 21 on the mobile frame 1, thereby flexibly adapting to small-range directional changes in dust diffusion and improving the accuracy and flexibility of dust suppression.

[0038] Scenario 1: Based on the dust suppression requirements of the water conservancy project construction area, if it is necessary to expand the dust suppression coverage area or increase the delivery distance of the atomized droplets, the user operates the controller program to cause the two electric push rods 42 to retract, driving the second connecting ring 43 to move. This causes the sliding cylinder 45 to slide on the outer wall of the fixed cylinder 31. At this time, the overall length of the sliding cylinder 45 and the fixed cylinder 31 becomes shorter. Simultaneously, during the sliding of the sliding cylinder 45, it synchronously drives the annular frame 46, several atomizing nozzles 72, several lifting rods 76, several arc-shaped fixed sleeves 77, and several arc-shaped sliding rods 78 to move synchronously. During the movement, the arc-shaped sliding rods 78, guided by the limiting groove 54, can gradually slide within the arc-shaped fixed sleeves 77. Simultaneously, the diameter of the annular ring formed by the arc-shaped fixed sleeves 77 and the arc-shaped sliding rods 78 gradually... The reduction in size causes several arc-shaped fixed sleeves 77 to correspondingly push several lifting rods 76 to slide into the annular frame 46, thereby pushing the connecting rod 73 to rotate inward by a certain angle. This causes several atomizing nozzles 72 to rotate at a certain angle away from the axis of the sliding cylinder 45 on the outer wall of several fixed shafts 71. The rotation angle range of the atomizing nozzles 72 is reasonably set, which can positively enhance the dust suppression effect, thereby achieving a geometric expansion of the atomization coverage area and an increase in the atomization delivery distance. This is suitable for large-area and long-distance dust control needs. Compared with the existing technology, which requires manual adjustment of nozzle angle and airflow channel length and has low adjustment efficiency and poor adaptability, the telescopic component 4 and the atomizing rotation component 7 can achieve adaptive adjustment, improving the efficiency and automation of dust suppression operations, while ensuring the stability of the dust suppression effect after adjustment.

[0039] To address the technical challenge of effectively controlling fine particulate dust, such as... Figure 7 and Figure 8 As shown, the following preferred technical solutions are provided: like Figure 8 As shown, the pulse assembly 8 includes a first conical ring 81 and a second conical ring 84 fixedly connected to the inner wall of the fixed cylinder 31. By setting one side of the first conical ring 81 and the second conical ring 84 to be conical, and with the conical surface facing the airflow direction, the airflow in the airflow conveying assembly 3 can be gathered, enhancing the concentration and velocity of the airflow when it passes through. At the same time, the inner diameter of the second conical ring 84 is larger than that of the first conical ring 81, which can form a gradual airflow channel, adapting to the generation and transmission of pulsed air waves, and improving the pressure intensity when the airflow is squeezed.

[0040] An electromagnetic ring 82 is installed inside the first conical ring 81, and a magnetic ring 85 is installed inside the second conical ring 84. The electromagnetic ring 82 and the magnetic ring 85 are coaxially arranged, and the distance between the electromagnetic ring 82 and the magnetic ring 85 is set reasonably to ensure that the electromagnetic ring 82 generates sufficient attraction to drive the magnetic ring 85 to move when energized, and that the magnetic ring 85 can smoothly return to its original position under the action of the spring 87 after the power is cut off, ensuring that the pulse assembly 8 stably generates pulsed air waves. An installation ring 83 is fixedly connected to the inner wall of the fixed cylinder 31. Several moving rods 86 are slidably connected inside the installation ring 83. One end of each of the moving rods 86 is fixedly connected to the second conical ring 84. A spring 87 is fixedly connected to one side of the installation ring 83, and the other end of each spring 87 is fixedly connected to the moving rod 86. The spring 87 is sleeved on the outer wall of the moving rod 86. The attraction structure, driven structure, and elastic structure in the pulse assembly 8 are the electromagnetic ring 82, the magnetic ring 85, and the spring 87, respectively.

[0041] Scenario 2: Based on the dust suppression requirements of the water conservancy project construction area, if it is necessary to improve the adsorption and capture effect of fine particulate dust, the electromagnetic ring 82 is energized by the user-operated controller program, gradually attracting the magnetic ring 85 and compressing the spring 87. When the magnetic ring 85 moves to fit against one side of the electromagnetic ring 82, the controller de-energizes the electromagnetic ring 82, releasing the electromagnetic ring 82 from the magnetic ring 85. The spring 87 then resets the magnetic ring 85 quickly. During the reset process of the magnetic ring 85, the airflow inside the fixed cylinder 31 is quickly compressed, forming a high-intensity pulsed air wave. This wave performs secondary shearing on the atomized droplets, making their particle size smaller. At the same time, the disturbed airflow further expands the droplet diffusion range. Compared with the existing technology, which has a coarser atomized droplet size, limited adsorption capacity for fine particulate dust, and a fixed atomization effect that cannot be dynamically adjusted, this technology can achieve precise refinement of the atomized droplet size and flexible control of the atomization effect, improving the efficiency of fine particulate dust treatment and adapting to the dust suppression needs of different particle sizes.

[0042] Simultaneously, the controller can adjust the frequency and speed of the electromagnetic ring 82 attracting the magnetic ring 85, thereby achieving the control of the frequency and speed of pulsed air wave generation. It can match different dust concentrations and dust particle sizes as needed, and can flexibly adjust the fineness and diffusion effect of atomized droplets according to the real-time changes of dust at the construction site, further enhancing the intelligent adaptability of the device, while avoiding unnecessary energy and water consumption, and balancing dust reduction efficiency and economic efficiency.

[0043] Scenario 3: When Scenario 1 and Scenario 2 are used in combination, the atomization coverage and conveying distance can be improved at the same time, and the atomized droplet particle size can be precisely refined. This forms a comprehensive and refined synergistic treatment of dust. Compared with the existing technology, which cannot simultaneously take into account the problems of large-scale long-distance dust suppression and fine particulate dust capture, and the independent adjustment and poor adaptability of each dust suppression function, this technology can give full play to the synergistic effect of telescopic linkage and pulse shearing, improve the device's adaptability to the complex dust conditions at water conservancy construction sites, and maximize the dust suppression effect.
