[0014] Also included is a method for using a dust suppression device for road and bridge construction:
[0015] The support placement platform is flexibly transported to the designated location, and the concentrated spray state or dispersed spray state of the conical atomizing bucket can be adjusted according to the use requirements before use;
[0016] Conical atomizing bucket dispersed spray state: by contracting the first telescopic rod and pulling back each conical arc plate hinged on the top of the outer tube body to unfold, the atomizing nozzles of each conical arc plate can spread the spray to all sides, achieving uniform dust reduction over a wide range;
[0017] Conical atomizing bucket centralized spraying state: the first telescopic rod is extended to push the conical arc plates hinged on the top of the outer tube to tighten and splice each other to form a complete cone shape, so that the atomizing nozzles on the conical arc plates can be concentrated, and the water mist sprayed by the atomizing nozzles can be gathered to concentrate dust reduction at specific locations where high-density water mist is required;
[0018] And while using the above two states, the angle of rotation of the movable shell and the conical atomizing bucket is adjusted forward and backward through the guide push component, so that the two conical atomizing buckets in the spray state can disperse the spray or concentrate the spray in the specified direction; and the driving mechanism drives the outer tube body to rotate back and forth horizontally on the upper side of the movable shell, so that no matter whether the conical atomizing bucket is in the dispersed spray state or the concentrated spray state, it can change the spray angle and direction following the rotation of the outer tube body.
[0019] By adopting the above technical solution, the present invention has the following advantages:
[0020] The present invention significantly improves the adaptability, operability, use effect and efficiency of the dust reduction equipment through its ingenious structure and innovative design. The conical protective frame is set to drive the flexible transportation of the conical water tank and the supporting placement platform to ensure that the equipment can be quickly positioned according to the operation requirements and adapt to the changing working environment such as roads and bridges. The designed conical atomizing bucket can switch between concentrated spray and dispersed spray states, so that the equipment can not only cover a large area to achieve uniform dust reduction, but also perform high-density water mist spraying for specific areas to meet different dust reduction requirements. At the same time, a guide push component and a drive mechanism are designed for coordinated use, so that the conical atomizing bucket can not only disperse or concentrate the spray in a specified direction, but also change the spray angle through the horizontal reciprocating rotation of the outer tube body, so as to ensure the accuracy and efficiency of the dust reduction operation.
[0021] Moreover, based on the above technical solution, an inner tube body is designed inside the outer tube body, and a fan is installed in the inner tube body. Therefore, when the conical atomizing bucket sprays, the airflow generated by the fan significantly enhances the thrust of the water mist. On the one hand, it can ensure that the spray can cover the designated area farther and more concentratedly, especially in the concentrated spray state of the conical atomizing bucket, the high-density water mist can be uniformly blown to the target direction to achieve a more effective dust reduction effect; on the other hand, the airflow of the fan works in coordination with the atomizing nozzle to improve the dispersion and uniformity of the atomized water droplets. Even in the concentrated spray mode, the water mist can be kept fine and uniform, thereby improving the dust reduction efficiency. Combined with the adjustment of the above-mentioned guide push component and the drive mechanism, the airflow direction and intensity of the fan can be controlled. The device can accurately adjust the spray angle and coverage of the water mist according to actual needs; on the other hand, since the bottom of the inner tube body is connected to the inside of the movable shell, the fan can simultaneously transport the heat generated by the electrical accessories of the movable shell to the outside when working, thereby improving the heat dissipation effect of the equipment, and the heat dissipated hot air acts on the water mist, which can make it produce a better dust reduction effect and improve the use effect and efficiency of the equipment; at the same time, an LED light ring is designed on the top of the inner tube body to improve the lighting effect at night, especially when the conical atomizing bucket is in a concentrated spray state and spraying water mist at night, the LED light ring cooperates with the reflective surface on the inside of the conical atomizing bucket to reflect and concentrate light, thereby more conveniently and accurately illuminating the position where water mist dust reduction is required;
[0022] The partition cavity is also connected to the inner side of the movable shell, and the bottom of the movable shell is hollowed out and corresponds to the top of the inverted conical water guide groove and the water inlet. In this way, part of the water mist flows along the partition cavity during the spraying process of the conical atomizing bucket. Through this design, part of the liquid condensed from the water mist can flow downward along the partition cavity and be recycled into the conical water tank, thereby improving its recycling rate.
[0023] In addition, the conical protective frame designed on the outside of the conical water tank can not only play the role of pushing, pulling, transporting and protecting the conical water tank, but also the user can step upwards along the annular steel ring of the conical protective frame to facilitate the maintenance and replacement of the upper parts of the equipment.

DETAILED DESCRIPTION
[0036] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.
[0037] like Figure 1-10As shown in the figure, the present invention provides a technical solution for a dust suppression device for road and bridge construction, including a supporting and placing platform 3, a movable shell 4 rotatably installed on the upper side of the supporting and placing platform 3 with front and rear axes, and an outer tube body 5 rotatably installed on the upper side of the middle of the movable shell body 4, the top of the outer tube body 5 is movably connected with a conical atomizing bucket 6, the conical atomizing bucket 6 is composed of three conical arc plates 61 distributed in a circular array, and the bottom of each conical arc plate 61 is hinged to the top of the outer tube body 5, a mounting frame 62 is fixedly welded to the middle part of the inner side of the conical arc plate 61, and two outwardly arranged atomizing nozzles 63 are installed on each mounting frame 62; three first telescopic rods 66 are hinged to the middle part of the outer tube body 5, and the telescopic ends of the three first telescopic rods 66 are respectively connected to the middle part of the outer sides of the three conical arc plates 61. The cone arc plate 61 is extended to control the concentrated spray state of the cone atomizing bucket 6, and the cone arc plate 61 is expanded to control the dispersed spray state of the cone atomizing bucket 6 by contracting and pulling back the first telescopic rod 66; the concentrated spray state and dispersed spray state of the cone atomizing bucket 6 can be switched, so that the device can not only cover a large area to achieve uniform dust reduction, but also carry out high-density water mist spraying for specific areas to meet different dust reduction needs, and the left and right sides of the supporting placement platform 3 are respectively provided with guide pushing components 7 for pushing the movable shell 4 to rotate back and forth and adjust the spray direction of the cone atomizing bucket 6, and one side of the movable shell 4 is provided with a device for driving the outer tube body 5 to rotate horizontally and adjust the cone atomizing bucket 6. The driving mechanism for controlling the spray direction of the bucket 6, through the coordinated use of the guide pushing component 7 and the driving mechanism, enables the conical atomizing bucket 6 to not only disperse or concentrate the spray in the specified direction, but also change the spray angle through the horizontal reciprocating rotation of the outer tube body 5, thereby ensuring the accuracy and efficiency of the dust reduction operation; specifically, the guide pushing component 7 includes a second telescopic rod 74 hinged on the left and right sides of the supporting placement platform 3 and an arc rod 71 fixed on the left and right sides of the supporting placement platform 3, an arc groove 72 is provided in the middle of the arc rod 71, the arc rod 71 and the arc groove 72 are centered on the bearing for the forward and backward rotation of the movable shell 4, and the left and right sides of the movable shell 4 are respectively provided with sliding ear blocks 43 that can slide in the arc groove 72, and the second telescopic rod 74 is extended to the left and right sides of the movable shell 4. The retracted end is rotatably connected to one side of the sliding ear block 43, and the sliding ear block 43 is controlled and pushed to slide forward or backward along the arc-shaped slide groove 72 by the extension and contraction of the two second telescopic rods 74. The movable shell 4 is rotated and flipped forward or backward, so that the outer tube body 5 and the conical atomizing bucket 6 are synchronously rotated forward to adjust the direction, and the spray is dispersed or concentrated in the specified direction. The arc rod 71 plays a guiding role in the rotation of the movable shell 4, making it more stable when rotating. The arc rods 71 on the upper and lower sides of the arc-shaped slide groove 72 are respectively rotatably embedded with a plurality of balls 73, and each ball 73 rolls against the sliding ear block 43 to reduce friction, so that the sliding ear block 43 can slide and displace on the arc-shaped slide groove 72 more flexibly and smoothly;
[0038] The driving mechanism includes a rotating motor 41 embedded in the upper side of the movable shell 4, a driving gear 411 is installed at the shaft end of the rotating motor 41, and the driving gear 411 is arranged inside the movable shell 4, and a driven gear 51 is fixedly provided on the outer side of the bottom of the outer tube 5, and the driving gear 411 is meshed with the driven gear 51 for transmission. The driving gear 411 is driven by the rotating motor 41, so that the driving gear 411 meshes with the driven gear 51 for transmission, so that the outer tube 5 can rotate horizontally on the movable shell 4, and cooperate with the above-mentioned movable shell 4 to be able to rotate forward as a whole, which means that the device can accurately aim at the dust source, and at the same time, by adjusting the spray angle, it can cover more hard-to-reach areas, greatly improving the accuracy and efficiency of the dust reduction operation, as well as the flexible controllability of the equipment.
[0039] In this embodiment, the inner tube body 8 is interspersed with the inner side of the outer tube body 5 at intervals, and a spacing cavity 10 is formed therebetween. The bottom of the inner tube body 8 is fixedly connected to the inner side of the movable shell 4 through a support rod, ensuring the stability of the structure and the smoothness of the airflow. An LED light ring 81 is installed on the top edge of the inner tube body 8. The LED light ring 81 is located on the inner side of the conical atomization bucket 6. This layout not only saves space, but also ensures that the light can directly illuminate the atomization area. The inner side of the conical arc plate 61 of the conical atomization bucket 6 is a reflective surface, and the reflective surface can be an orange peel pattern or a scale pattern. The function is to reflect the light of the LED light ring 81 on the inner wall of the conical atomization bucket 6. Especially when working at night or in a low-light environment, when the conical atomization bucket 6 is in a concentrated spray state, the reflective surface can concentrate and reflect the light to illuminate the spray area, ensuring that the operator can clearly see the position of the water mist dust reduction, thereby improving the accuracy and safety of the dust reduction operation.
[0040] At the same time, a fan 82 is installed on the inner side of the inner tube body 8, and the outer tube body 5 and the lower side of the inner tube body 8 are provided with air inlet vents 11 distributed in a circular array. The air inlet vents 11 are located below the fan 82 and are connected to the partition cavity 10. The fan 82 installed on the inner side of the inner tube body 8 works together with the air inlet vents 11 on the lower side of the outer tube body 5 and the inner tube body 8 to form an effective air circulation effect; the air inlet vents 11 are distributed in a circular array to ensure uniform air intake, and are directly connected to the partition cavity 10 through the bottom of the fan 82, thereby enhancing the efficiency of air flow. The design of the fan 82 has the following use effects: first, the airflow generated by the fan 82 significantly enhances the thrust of the water mist, which can ensure that the spray can cover the designated area farther and more concentratedly, especially in the concentrated spray state of the conical atomizing bucket 6, the high-density water mist can be uniformly blown to the target direction to achieve a more effective dust reduction effect;
[0041] Secondly, the airflow of the fan 82 works in coordination with the atomizing nozzle 63 to improve the dispersion and uniformity of the atomized water droplets. Even in the concentrated spray mode, the water mist can be kept fine and uniform, thereby improving the dust reduction efficiency. In combination with the adjustment of the above-mentioned guide push component 7 and the drive mechanism, the airflow direction and intensity of the fan 82 are controllable, so that the device can accurately adjust the spray angle and coverage of the water mist according to actual needs;
[0042] Finally, since the bottom of the inner tube body 8 is connected to the interior of the movable shell 4, the fan 82 can simultaneously transport the heat generated by the electrical components inside the movable shell 4 to the outside when working, thereby improving the heat dissipation effect of the equipment. The hot air during heat dissipation acts on the water mist, which can produce a better dust reduction effect and improve the use effect and efficiency of the equipment. When the movable shell 4 rotates and flips forward, the bottom is separated from the supporting placement platform 3, allowing the inside of the movable shell 4 to be completely connected to the external air, allowing the fan 82 to have a larger air intake and increase the air output.
[0043] In the above technical solution, a water pump 44 is installed on the inner side of the movable shell 4, and the inner tube body 8 and the partition cavity 10 are both connected to the inner side of the movable shell 4, so that the airflow generated by the fan 82 not only helps the atomization process, but also cooperates with the lighting function of the LED light ring 81. The airflow of the fan 82 can accelerate the diffusion of water mist and blow dust at the designated position, while the lighting of the LED light ring 81 ensures that the operator can clearly observe the spraying situation under any lighting conditions, especially at night or in low-light environments. The combination of the fan and lighting significantly improves the visibility and operating efficiency of the equipment; at the same time, by connecting a water outlet hose 64 on one side of each atomizing nozzle 63, the water outlet hose 64 is inserted through the partition cavity 10 and connected to the water outlet flange of the water pump 44, and the distance of the water outlet hose 64 needs to meet the dispersed spray State and the length of the outer tube body 5 when it rotates, so that the water outlet hose 64 can move inside the partition cavity 10, when the conical atomizing bucket 6 is changed from the concentrated spray state to the dispersed spray state, its water outlet hose 64 can be pulled up along the partition cavity 10 Part of the length, and when the conical atomizing bucket 6 is changed from the dispersed spray state to the concentrated spray state, the water outlet hose 64 can go down along the partition cavity 10 into the inside of the movable shell 4, and the water inlet end of the water pump 44 is connected to a water inlet hose 65, which passes through the inverted cone-shaped water guide groove 31 and the water inlet 9 and is arranged inside the conical water tank 1 for pumping water, and the length of the water inlet hose 65 is also relatively long, so that when the movable shell 4 is rotated and flipped forward and the outer tube body 5 is rotated horizontally, the water inlet end at the bottom is always kept in communication with the inside of the conical water tank 1, and water is not easily cut off.
[0044] Among them, the bottom of the movable shell 4 is hollow. Since the bottom of the inner tube body 8 is connected to the interior of the movable shell 4, the fan 82 can synchronously transmit the heat generated by the water pump 44 and the rotating motor 41 inside the movable shell 4 and the LED light ring 81 installed on the top of the inner tube body 8 to the outside when working, thereby improving the heat dissipation effect of the equipment. At the same time, the hot air can act on the water mist. The hot air can accelerate the evaporation process of the water mist. Because the kinetic energy of water molecules increases under high temperature environment, it is easier to change from liquid to gas, thereby improving the evaporation efficiency. With the rapid evaporation of the water mist, negative ions and smaller water droplets will be generated. These water droplets can more effectively absorb dust particles in the air, thereby improving the dust reduction efficiency and enhancing the dust reduction effect.
[0045] In the present embodiment, it also includes a conical water tank 1 and a conical protective frame 2 for placing and fixing the conical water tank 1, the supporting placement platform 3 is fixedly installed on the conical water tank 1 and the top of the conical protective frame 2, and the conical water tank 1 and the supporting placement platform 3 are flexibly transported by the conical protective frame 2 to ensure that the equipment can be quickly positioned according to the working requirements, and the conical protective frame 2 can effectively improve the structural stability and strength of the conical water tank 1, and effectively support the supporting placement platform 3; wherein a water inlet 9 is provided on the top of the conical water tank 1, and an inverted conical water guide groove 31 connected to the bottom of the water inlet 9 is provided in the middle of the supporting placement platform 3, the inverted conical water guide groove 31 is connected to the inner side of the movable shell 4, and the inverted conical water guide groove 31 is located below the movable shell 4, so that during the spraying process of the conical atomizing bucket 6, part of the water condensed from the water mist can flow along The liquid flows into the inner side of the movable shell 4 along the partition cavity 10, and flows downward through the movable shell 4 and falls into the inverted cone-shaped water guide groove 31. Since the inverted cone-shaped water guide groove 31 is in an inverted cone shape, the received liquid can be guided to the water receiving port 9 and then recycled into the conical water tank 1, so that the liquid can be collected and the waste of resources can be reduced. It is further provided that the bottom surfaces of each air inlet port 11 are inclined inwardly, so when the outer tube body 5 is in vertical use, the liquid can flow along the inner wall of the outer tube body 5, and under the action of the inclined surface of the bottom of the air inlet port 11, it is not easy to flow out to the outside. Of course, the front part of the outer tube body 5 can choose not to open the air inlet port 11, and open the air inlet port 11 in a circular shape on the left, right and rear sides. Therefore, when the outer tube body 5 tilts forward, the inner wall of the front part can be used as a guide surface, which makes it difficult for the liquid in the partition cavity 10 to flow out from the air inlet port 11.
[0046] Among them, a push-pull handle 21 is fixedly installed on the rear side of the conical protective frame 2, a bottom plate 22 is fixedly provided at the bottom of the conical protective frame 2, the conical water tank 1 is fixedly placed on the upper side of the bottom plate 22, and a plurality of walking wheels 23 are installed on the lower side of the bottom plate 22 for rapid transportation to a designated position, and three annular steel rings 24 are welded on the outer side of the conical protective frame 2, which fit tightly to the side surface of the conical water tank 1. These annular steel rings 24 are layered upward according to the shape of the conical protective frame 2, and the upper layers of the annular steel rings 24 have smaller diameters. Therefore, it can not only provide protection, but also allow users to step on it, making it convenient for maintenance and replacement of spare parts on the top.
[0047] The present invention also includes a specific method for using the dust suppression device:
[0048] By holding the push-pull handle 21, the user can flexibly transport the conical water tank 1, the supporting placement platform 3 and the above components on the entire conical protection frame 2 to the designated position. Before spraying, the user can adjust the concentrated spray state or the dispersed spray state of the conical atomizing bucket 6 according to the use requirements, and can also adjust the state during spraying. The spray is mainly carried out by the water pump 44 inside the movable shell 4 to pump water in the conical water tank 1 and transport it to the atomizing nozzle 63 inside the conical atomizing bucket 6 to spray water mist;
[0049] When adjusting the dispersed spray state of the conical atomizing bucket 6: the first telescopic rod 66 is retracted and each conical arc plate 61 hinged on the top of the outer tube body 5 is pulled back to unfold, so that the atomizing nozzle 63 of each conical arc plate 61 can spread the spray to four sides, thereby achieving uniform dust reduction over a wide range;
[0050] When the conical atomizing bucket 6 is adjusted to a concentrated spray state: the first telescopic rod 66 is extended to push the conical arc plates 61 hinged on the top of the outer tube body 5 to tighten and splice each other to form a complete conical shape, so that the various atomizing nozzles 63 on the conical arc plates 61 can be concentrated, and the water mist sprayed by the atomizing nozzles 63 can be gathered to concentrate dust reduction at specific locations where high-density water mist is required;
[0051] And while using the above two spraying states, the two second telescopic rods 74 of the guide push assembly 7 are extended and retracted to control the sliding ear block 43 to slide forward or backward along the arc-shaped slide groove 72, wherein the sliding ear block 43 is in sliding contact with the balls 73 on the upper and lower sides of the arc-shaped slide groove 72 to reduce the friction force, so that the movable shell 4 can be flexibly and smoothly rotated forward or backward, so that the outer tube body 5 and the conical atomizing bucket 6 can be synchronously rotated forward to adjust the direction, and the conical atomizing bucket 6 can be used in the specified direction in two states of dispersed spray or concentrated spray;
[0052] Then, the driving mechanism drives the driving gear 411 by rotating the motor 41, so that the driving gear 411 meshes with the transmission driven gear 51, and the outer tube body 5 reciprocates horizontally on the movable shell 4. No matter whether the conical atomizing bucket 6 is in a dispersed spray state or a concentrated spray state, it can change the spray angle and direction to be used by following the rotation of the outer tube body 5, and cooperate with the above-mentioned movable shell 4 to rotate forward as a whole, so that the conical atomizing bucket 6 of the device can be accurately aimed at the dust source, and at the same time, by adjusting the spray angle, more hard-to-reach areas can be covered, which greatly improves the accuracy and efficiency of the dust reduction operation, as well as the flexible controllability of the device;
[0053] And by turning on the fan 82 and the LED light ring 81 to cooperate with the above-mentioned conical atomization bucket 6, the airflow generated by the fan 82 significantly enhances the thrust of the water mist in the concentrated spray state, which can ensure that the spray can cover the designated area farther and more concentratedly, and achieve a more effective dust reduction effect; at the same time, it can transport the hot air inside the movable shell 4 to the external conical atomization bucket 6, and then dissipate the heat inside the movable shell 4 while also allowing the hot air to act on the water mist, which is beneficial to further improve the sedimentation effect of the water mist; and the lighting function of the LED light ring 81 can be used in conjunction with the fan 82 and the spliced conical atomization bucket 6, and the airflow of the fan 82 can accelerate the diffusion of the water mist and blow dust at the designated position, and the inner side of the conical atomization bucket 6 is provided with a reflective surface, which can reflect and concentrate light at night, so as to accurately correspond to the required dust reduction position, and ensure that the operator can clearly observe the spray situation under low light conditions, significantly improving the visibility and operating efficiency of the equipment.
