Description

Technical Field

[0001] This invention relates to the field of dust suppression device technology, specifically a dust suppression device for road and bridge construction. Background Technology

[0002] Dust pollution is a critical problem that needs to be solved during road and bridge construction. The excavation, material transportation and loading / unloading, and concrete mixing processes all generate a large amount of dust particles, which causes the air quality at and around the construction site to deteriorate rapidly.

[0003] Patent CN219252062U relates to the field of road technology. This road dust suppression device includes a mobile frame with a support frame fixedly connected inside. A water tank is mounted on the top of the mobile frame, a fixed frame is mounted on the top of the support frame, and a connecting plate is mounted on the top of the fixed frame. An atomizing nozzle is fixedly connected to one end of the connecting plate. A water pump is fixedly connected inside the water tank, and a connecting pipe is fixedly connected to the outside of the atomizing nozzle. The connecting plate is connected to the fixed frame via a connector. When the angle of the atomizing nozzle needs to be adjusted, rotating a handle causes a fixedly connected worm gear to rotate, which in turn drives a meshing worm wheel to rotate. The worm wheel then drives a rotating rod, which in turn adjusts the angle of the fixedly connected connecting plate. The atomizing nozzle treats dust at different heights. Although this device allows for nozzle position adjustment, it is prone to water mist dispersion during spraying in windy conditions, making it difficult to guarantee the spraying effect and area. Therefore, a dust suppression device for road and bridge construction is proposed to solve the aforementioned problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a dust suppression device for road and bridge construction, which addresses the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: a dust suppression device for road and bridge construction, comprising an electric slide rail, an installation plate mounted on the moving end of the electric slide rail, a threaded rod rotatably connected to the inner wall of the installation plate, a telescopic rod fixedly connected to the bottom of the installation plate, a fixed plate fixedly connected to the telescopic end of the telescopic rod, a spraying device rotatably connected to the inner wall of the fixed plate, an atomizing mechanism for agitating water into mist provided at the bottom of the fixed plate, a spray head mounted at the bottom of the spraying device, gears fixedly connected to both sides of the spraying device, a water tank fixedly connected to the bottom of the electric slide rail, and a conveying pipe fixedly connected to the inner wall of the water tank. When the dust suppression equipment needs maintenance or adjustment, the threaded rod is rotated by a motor, which moves the spray head to the corresponding position, allowing adjustment of the spray height to improve the efficiency of road dust suppression. When equipment malfunctions, it reduces the number of steps required for maintenance by operators, improving work efficiency. Distillation water return channels are provided on the front and rear sides of the electric slide rail for distillation and water collection. The telescopic rod has wind baffles hinged to its fixed section on both sides via torsion springs. Telescopic rods are hinged to both sides of the wind baffles, and an arc-shaped rack is slidably connected to the telescopic end of the telescopic rod. When wind blows towards the equipment, the wind baffles drive the spraying device to rotate against the wind. Spraying against the wind reduces wind interference with the water mist, allowing the water mist to cover the target area more evenly, thus improving spraying efficiency. This not only improves spraying efficiency and reduces drift but also enhances the equipment's adaptability and stability. The mounting plate moves via an electric sliding mechanism. Along the track's movement trajectory, a motor is fixedly connected to the top of the mounting plate, and the motor's output end is fixedly connected to the top of the threaded rod. The circumferential surface of the threaded rod is threadedly connected to the inner wall of the fixed plate. The water tank is used to store water resources for dust suppression spraying. The conveying pipe is used to transport the water from the tank to the interior of the spraying device. The spray head is used to spray and suppress dust. The top of the arc-shaped rack is hinged to the bottom of the telescopic rod, and the bottom of the arc-shaped rack meshes with the circumferential surface of the gear. The wind baffle is used to block the incoming wind. Preferably, the atomizing mechanism includes a connecting frame, with an atomizing plate rotatably connected to the inner wall of the connecting frame. A gear two is fixedly connected to the end of the atomizing plate near gear one. When the spraying device oscillates, gear one drives the atomizing plate to oscillate, atomizing the water into a mist, thus increasing the spraying area and the density of the atomized particles. This allows for better capture of airborne dust, stronger dust suppression, and higher efficiency. It also further conserves water resources, reduces equipment maintenance costs, and improves the comfort and air quality of the working environment to some extent. A C-shaped frame is fixedly connected to the bottom of the spraying device. A threaded rod two is rotatably connected to the inner wall of the C-shaped frame. Gear three is fixedly connected to both ends of the threaded rod two. A scraper rod is threaded onto the circumferential surface of the threaded rod two. A limiting rod is fixedly connected to the inner wall of the frame, and a semi-circular rack is fixedly connected to the bottom of the fixed plate. During spraying, the spraying device swings to drive the scraper to scrape the bottom of the spray head, which can remove dust and impurities from the nozzle surface, prevent clogging, and ensure spraying effect. This not only increases the flexibility of the nozzle, but also generates tangential motion force when it hits the guide plate, so that the nozzle can spray in a fan shape within the range of the limiter, while further reducing the maintenance cost of the equipment. The top of the connecting frame is fixedly connected to the bottom of the fixed plate. The circumferential surface of the second gear meshes with the circumferential surface of the first gear. The atomizing plate is used to beat the water mist into a mist. The circumferential surface of the limiting rod contacts the inner wall of the scraper. The scraper moves on the movement trajectory of the spray head. The circumferential surface of the semi-circular rack meshes with the circumferential surface of the third gear.

[0006] Preferably, the distilled water recovery mechanism includes a fixed frame, a storage box fixedly connected to the inner wall of the fixed frame, a condenser plate fixedly connected to the inner wall of the storage box, and a fixed pipe fixedly connected to the inner wall of the storage box. During dust suppression spraying, water is condensed by the condenser plate and collected inside the storage box. The water is then transported to a water tank via the fixed pipe. This effectively reduces water waste, improves water utilization, saves water resources, increases energy reuse efficiency, reduces environmental pollution, extends equipment lifespan, and lowers maintenance costs. A telescopic hinge rod is hinged to the top of the fixed plate, and a positioning block is hinged to the bottom of the telescopic hinge rod. The positioning block is located away from... A push plate is fixedly connected to one side of the telescopic hinge rod. While spraying, the atomizing plate drives the push plate to push out the water on its outer surface, preventing dust from adhering to the water molecules on the circumference of the atomizing plate. This improves the beating effect of the atomizing plate, extends the service life of the equipment, and reduces maintenance costs. It not only improves dust reduction efficiency and water resource utilization but also optimizes the working environment. The front and rear sides of the mounting plate are fixedly connected to the fixing frame. The storage box is used to collect distilled and condensed water. The condensing plate is used to condense and collect the distilled water. The side of the fixing pipe away from the storage box is fixedly connected to the inner wall of the water tank, and the fixing pipe is used to transport the collected water into the interior of the water tank. The inner wall of the push plate is in contact with the outer surface of the atomizing plate.

[0007] The present invention, by adopting the above technical solution, can bring the following beneficial effects: 1. This dust suppression device for road and bridge construction utilizes the coordinated operation of an electric slide rail, mounting plate, threaded rod, telescopic rod, fixing plate, water tank, delivery pipe, spraying device, windbreak plate, telescopic tie rod, arc rack, gear, and spraying head. When the dust suppression equipment requires maintenance or adjustment, the motor drives the threaded rod to rotate, which in turn moves the spraying head to the corresponding position. Adjusting the spraying height improves the efficiency of road dust suppression. When equipment malfunctions, it reduces the number of steps required for maintenance, increasing work efficiency. When wind blows towards the equipment, the windbreak plate rotates the spraying device to the opposite wind direction. Spraying against the wind reduces wind interference with the water mist, allowing the water mist to cover the target area more evenly, thereby improving spraying efficiency. This not only improves spraying efficiency and reduces drift but also enhances the adaptability and stability of the equipment.

[0008] 2. This dust suppression device for road and bridge construction operates in coordination with the connecting frame, gear 2, and atomizing plate. When the spraying device swings, gear 1 drives the atomizing plate to swing, agitating the water into a mist. This results in a larger spraying area and denser atomized particles, which can capture airborne dust, suppress dust more effectively, and increase efficiency. It also saves water resources, reduces equipment maintenance costs, and improves the comfort of the working environment and air quality to a certain extent.

[0009] 3. This dust suppression device for road and bridge construction utilizes the coordinated operation of a C-shaped frame, a threaded rod, a limiting rod, a scraper, a semi-circular rack, and a gear. While spraying, the spraying device swings, causing the scraper to scrape the bottom of the spray head, removing dust and impurities from the nozzle surface, preventing clogging, and ensuring effective spraying. This not only increases the flexibility of the nozzle but also generates tangential force upon impact with the guide plate, allowing the nozzle to spray in a fan shape within the limiter's range, further reducing equipment maintenance costs.

[0010] 4. This dust suppression device for road and bridge construction, through the coordinated operation of a fixed frame, storage box, condensation plate, and fixed pipe, allows water to be collected inside the storage box by condensation of the condensation plate while spraying dust. The water is then transported to the water tank through the fixed pipe. This effectively reduces water waste, improves water utilization, saves water resources, improves energy reuse efficiency, reduces environmental pollution, extends the service life of the equipment, and lowers maintenance costs.

[0011] 5. This dust suppression device for road and bridge construction, through the coordinated operation of the push plate, positioning block, and telescopic hinge rod, sprays water while the atomizing plate drives the push plate to push the water on its outer surface, preventing dust from adhering to the water molecules on the circumference of the atomizing plate, improving the beating effect of the atomizing plate, extending the service life of the equipment, reducing maintenance costs, improving dust suppression efficiency and water resource utilization, and optimizing the working environment.

[0014] 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.

[0015] Please see Figures 1-7 One embodiment of the present invention is: a dust suppression device for road and bridge construction, including an electric slide rail 1, an installation plate 2 installed on the movable end of the electric slide rail 1, a threaded rod 3 rotatably connected to the inner wall of the installation plate 2, a telescopic rod 4 fixedly connected to the bottom of the installation plate 2, a fixed plate 5 fixedly connected to the telescopic end of the telescopic rod 4, a spraying device 10 rotatably connected to the inner wall of the fixed plate 5, an atomizing mechanism 6 for agitating water into mist provided at the bottom of the fixed plate 5, a spraying head 14 installed at the bottom of the spraying device 10, gears 13 fixedly connected to both sides of the spraying device 10, a water tank 8 fixedly connected to the bottom of the electric slide rail 1, and a conveying pipe 9 fixedly connected to the inner wall of the water tank 8; During bridge construction or daily traffic operation, the electric sliding rail 1 can be activated. The electric sliding rail 1 moves the mounting plate 2 reciprocally via its movable end. This reciprocating movement of the mounting plate 2 drives the water tank 8, which in turn drives the delivery pipe 9. Simultaneously, the mounting plate 2 moves the telescopic rod 4 reciprocally. The telescopic rod 4, through its telescopic end, drives the fixed plate 5, which in turn drives the spraying device 10. The spraying device 10 then drives the spray heads 14 to reciprocate. At this point, activating the spraying device 10 again causes the spray heads 14 to spray and suppress dust, achieving ground dust control. The integration of water-based dust suppression and aerial spraying improves the overall dust suppression effect. When maintenance or adjustment is required, the motor on the top of the mounting plate 2 can be started. The motor will drive the threaded rod 3 to rotate through the output end. The rotation of the threaded rod 3 will connect with the inner wall of the fixing plate 5 through the circumferential surface, thereby moving the fixing plate 5. The fixing plate 5 will drive the spraying device 10 to move, and the spraying device 10 will drive the spray head 14 to the corresponding position. The spraying height can be adjusted to improve the efficiency of road dust suppression. When the equipment malfunctions, the number of operation steps for operators during maintenance is reduced, thus improving work efficiency. The electric slide rail 1 is equipped with a distillation water recovery mechanism 7 for distillation and water collection on both the front and rear sides. The fixed section of the telescopic rod 4 is hinged with a wind baffle 11 on both the front and rear sides by a torsion spring. The wind baffle 11 is hinged with a telescopic pull rod 15 on both sides. The telescopic end of the telescopic rod 4 is slidably connected with an arc-shaped rack 12. The mounting plate 2 moves on the movement trajectory of the electric slide rail 1. The top of the mounting plate 2 is fixedly connected with a motor. The output end of the motor is fixedly connected with the top of the threaded rod 3. The circumferential surface of the threaded rod 3 is threadedly connected to the inner wall of the fixed plate 5. The water tank 8 is used to store water resources for dust suppression spraying. The conveying pipe 9 is used to transport the water inside the water tank 8 to the inside of the spraying device 10. The spray head 14 is used to spray dust suppression. The top of the arc-shaped rack 12 is hinged to the bottom of the telescopic pull rod 15. The bottom of the arc-shaped rack 12 meshes with the circumferential surface of the gear 13. The wind baffle 11 is used to block the wind blowing in. This device is installed on the bridge top. Because the bridge top is at a high position, it generates greater wind pressure. When the wind blows towards the device, the wind deflector 11 will block the oncoming wind. When the wind is blocked, the wind deflector 11 will swing. The swing of the wind deflector 11 will drive the telescopic rod 15 to move through the hinge point. The movement of the telescopic rod 15 will drive the arc-shaped rack 12 to slide at the telescopic end of the telescopic rod 4 through the hinge point. The sliding of the arc-shaped rack 12 will mesh with the circumferential surface of the gear 13 at the bottom, thereby driving the gear 13 to rotate. The rotation of the gear 13 will drive the spraying device 10 to rotate. At this time, the rotation direction of the spraying device 10 will be opposite to the oncoming wind. Spraying against the wind can reduce the interference of the wind on the water mist, so that the water mist covers the target area more evenly, thereby improving the spraying efficiency. It can not only improve the spraying efficiency and reduce drift, but also enhance the adaptability and stability of the equipment.

[0016] Working principle: When the dust suppression equipment needs maintenance or adjustment, the motor drives the threaded rod 3 to rotate, which in turn moves the spray head 14 to the corresponding position. This allows for adjustment of the spray height, improving the efficiency of road dust suppression, reducing the number of steps required for maintenance, and increasing work efficiency. When the wind blows towards the equipment, the wind baffle 11 drives the spraying device 10 to rotate against the wind. Spraying against the wind reduces the interference of the wind on the water mist, allowing the water mist to cover the target area more evenly, thereby improving spraying efficiency.

[0017] Please see Figures 1-7 Based on the above embodiments, in another embodiment of the present invention, the atomizing mechanism 6 includes a connecting frame 61, an atomizing plate 63 is rotatably connected to the inner wall of the connecting frame 61, and a gear 62 is fixedly connected to one end of the atomizing plate 63 near the gear 13. As the spraying device 10 swings, the rotation of gear 13 meshes with the circumferential surface of gear 2 62, thereby driving gear 2 62 to rotate. The rotation of gear 2 62 drives the atomizing plate 63 to swing back and forth. At this time, the spray head 14 will spray water. The swinging of the atomizing plate 63 will agitate the water sprayed by the spray head 14 into a water mist, thereby making the spraying area larger and the atomized particles denser. This can capture floating dust in the air, suppress dust more effectively, and increase efficiency. At the same time, it further saves water resources, reduces equipment maintenance costs, and improves the comfort of the working environment and air quality to a certain extent.

[0018] A C-shaped frame 64 is fixedly connected to the bottom of the spraying device 10. A threaded rod 65 is rotatably connected to the inner wall of the C-shaped frame 64. Gears 69 are fixedly connected to both ends of the threaded rod 65. A scraper 67 is threadedly connected to the circumferential surface of the threaded rod 65. A limit rod 66 is fixedly connected to the inner wall of the C-shaped frame 64. A semi-circular rack 68 is fixedly connected to the bottom of the fixing plate 5. The top of the connecting frame 61 is fixedly connected to the bottom of the fixing plate 5. The circumferential surface of gear 62 meshes with the circumferential surface of gear 13. The atomizing plate 63 is used to atomize water mist. The circumferential surface of the limit rod 66 contacts the inner wall of the scraper 67. The scraper 67 moves on the trajectory of the spray head 14. The circumferential surface of the semi-circular rack 68 meshes with the circumferential surface of gear 69. While spraying, the oscillating of the spraying device 10 will cause the C-shaped frame 64 to oscillate, which in turn causes the threaded rod 65 to oscillate. The threaded rod 65, in turn, causes the gear 69 to oscillate. When the gear 69 oscillates, it meshes with the circumferential surface of the semi-circular rack 68, thereby causing the gear 69 to rotate. This rotation of the gear 69 will then cause the threaded rod 65 to rotate. The rotating threaded rod 65 will then contact the inner wall of the scraper 67 through the threaded groove on its circumferential surface, thus moving the scraper 67 forward. The swinging motion will cause the scraper 67 to move to the left, and when it moves backward, it will cause the scraper 67 to move to the right, thereby scraping the bottom of the spray head 14. This can remove dust and impurities from the nozzle surface, prevent clogging, and ensure the spraying effect. It not only increases the flexibility of the nozzle, but also generates tangential force when it hits the guide plate, so that the nozzle can spray in a fan shape within the range of the limiter. At the same time, it further reduces the maintenance cost of the equipment. The limit rod 66 will limit the scraper 67 to prevent the scraper 67 from deviating.

[0019] Working principle: When the spraying device 10 swings, the gear 13 drives the atomizing plate 63 to swing, agitating the water into a mist, thereby increasing the spraying area and making the atomized particles more concentrated. This allows for the capture of airborne dust, resulting in stronger dust suppression and higher efficiency. Simultaneously, the swinging of the spraying device 10 drives the scraper 67 to scrape the bottom of the spray head 14, removing dust and impurities from the nozzle surface to prevent clogging, ensure spraying effect, and further reduce equipment maintenance costs.

[0020] The distilled water recovery mechanism 7 includes a fixed frame 71, a storage box 72 fixedly connected to the inner wall of the fixed frame 71, a condenser plate 73 fixedly connected to the inner wall of the storage box 72, and a fixed pipe 74 fixedly connected to the inner wall of the storage box 72. While spraying to suppress dust, the water vapor around the equipment becomes heavy due to the spraying from the spray head 14. At this time, the water vapor evaporates under the sun and is condensed by the condenser plate 73, which then condenses at the bottom of the condenser plate 73. After the water condenses, it slowly flows into the storage box 72 for collection. Once the water is collected, it is transported from the storage box 72 to the water tank 8 through the fixed pipe 74 for spraying. By condensing and recycling the water, water waste can be effectively reduced, water utilization can be improved, water resources can be saved, energy reuse efficiency can be improved, environmental pollution can be reduced, the service life of the equipment can be extended, and maintenance costs can be reduced. The top of the fixed plate 5 is hinged with a telescopic hinge rod 77, and the bottom of the telescopic hinge rod 77 is hinged with a positioning block 76. A push plate 75 is fixedly connected to the side of the positioning block 76 away from the telescopic hinge rod 77. The front and rear sides of the mounting plate 2 are fixedly connected to the fixed frame 71. The storage box 72 is used to collect the distilled and condensed water. The condensing plate 73 is used to condense and collect the distilled water. The side of the fixed pipe 74 away from the storage box 72 is fixedly connected to the inner wall of the water tank 8, and the fixed pipe 74 is used to transport the collected water into the interior of the water tank 8. The inner wall of the push plate 75 is in contact with the outer surface of the atomizing plate 63. While spraying, the reciprocating oscillation of the atomizing plate 63 will cause the push plate 75 to oscillate as well. At this time, telescopic hinge rods 77 are hinged on both sides of the push plate 75. The telescopic hinge rods 77 will oscillate with the push plate 75. The other end of the telescopic hinge rod 77 is hinged to the bottom of the fixed plate 5. Thus, the push plate 75 will push the water on the outer surface of the atomizing plate 63 through the hinge, avoiding dust from adhering to the water molecules on the circumference of the atomizing plate 63. This improves the beating effect of the atomizing plate 63, extends the service life of the equipment, and reduces maintenance costs. It not only improves dust reduction efficiency and water resource utilization, but also optimizes the working environment.

[0021] Working principle: While spraying to suppress dust, water is condensed by the condenser plate 73 and collected inside the storage box 72. The water is then transported to the water tank 8 through the fixed pipe 74, which can effectively reduce water waste and improve water utilization. At the same time as spraying, the atomizing plate 63 drives the pusher plate 75 to push the water on its outer surface, preventing dust from adhering to the water molecules on the circumference of the atomizing plate 63, improving the beating effect of the atomizing plate 63 and extending the service life of the equipment.

[0022] This invention provides a dust suppression device for road and bridge construction. Many methods and approaches exist for implementing this technical solution; the above description is merely a preferred embodiment of the invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this invention, and these improvements and modifications should also be considered within the scope of protection of this invention. All components not explicitly stated in this embodiment can be implemented using existing technologies.
