Description

Technical Field

[0001] This utility model relates to the field of urban road cleaning technology, and in particular to an urban road dust suppression device. Background Technology

[0002] Dust is inevitable during outdoor construction on urban roads, especially in summer when the temperature is high and the climate is dry. Excessive dust inhalation can have a significant impact on the health of workers, so dust suppression devices need to be used regularly.

[0003] An existing dust suppression device for urban roads (publication number: CN220990167U) has at least the following drawbacks: The device uses a motor to drive a rotating plate to rotate, which in turn drives the plug-in column to rotate, causing the guide rail and the movable column to move horizontally. Two sets of limit blocks squeeze the squeezing column, which in turn causes the bracket to drive the nozzle to rotate. However, the height of the oscillating nozzle is fixed, and the spraying range is limited, making it difficult to spray dust in higher areas, resulting in poor dust suppression effect. Therefore, we propose this utility model. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a dust suppression device for urban roads.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A dust suppression device for urban roads includes a primary platform with an installation groove on its top surface. A secondary platform is connected to the installation groove via a spline. A tertiary platform is connected to the secondary platform with a movable groove on its top surface via a spline. A fog cannon body is mounted on the top surface of the tertiary platform. A lifting structure is provided inside the installation groove. The lifting structure includes a fixed groove on the bottom surface of the installation groove. A screw is rotatably mounted inside the fixed groove. A threaded hole is provided on the bottom surface of the secondary platform. The screw is threadedly connected to the threaded hole on the bottom surface of the secondary platform. A worm gear is fixed to the outer circular wall of the screw.

[0007] As a further embodiment of this utility model, a connecting groove is provided on one side of the primary platform, which is connected to the fixed groove. A worm gear is rotatably installed inside the connecting groove. A drive motor is fixed on one side of the primary platform, and the output end of the drive motor is fixed to one end of the worm gear. Two sliding holes are provided on the outer circular wall of the secondary platform, which are arranged opposite to each other. A connecting strip is slidably installed inside each of the two sliding holes. One end of each connecting strip is fixed to the outer circular wall of the tertiary platform, and the other end of each connecting strip is fixed to the inner bottom surface of the mounting groove.

[0008] As a further embodiment of this utility model, the sliding hole is provided with a plurality of rollers that rotate inside. The plurality of rollers are evenly distributed along the depth direction of the sliding hole, and the outer circular wall surfaces of the plurality of rollers are all in contact with the bottom surface of the connecting belt.

[0009] As a further embodiment of this utility model, a first gear is rotatably mounted on the top surface of the three-level platform, a second gear meshes with one side of the first gear, the top surface of the first gear is fixed to the bottom surface of the fog cannon body, a servo motor is fixed on the top surface of the three-level platform, and the output end of the servo motor is fixed to the second gear.

[0010] As a further embodiment of this utility model, the top surface of the three-level platform is provided with a through hole, and a connecting shaft is rotatably arranged inside the through hole. The top end of the connecting shaft is fixed to the bottom surface of the first gear, and an anti-detachment ring is fixed to the outer circular wall of the connecting shaft. A limit groove is provided on the inner circular wall of the through hole, and the anti-detachment ring and the limit groove are rotatably arranged inside the through hole.

[0011] As a further embodiment of this utility model, a stabilizing groove is provided on the inner bottom surface of the fixing groove, and the bottom end of the screw is rotatably connected to the inside of the stabilizing groove.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This dust suppression equipment, through its lifting structure, allows operators to activate a drive motor that rotates a screw. The screw's rotation lifts the secondary platform. As the secondary platform rises, the connecting belt, fixed to the bottom of the mounting slot, pulls the tertiary platform upwards within the movable slot. This tertiary platform's rise increases the height of the fog cannon, enabling it to effectively suppress dust in higher areas, expanding the cannon's spray range, and improving the device's dust suppression efficiency.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] like Figures 1-4 As shown, a dust suppression device for urban roads includes a primary platform 1. The top surface of the primary platform 1 has an installation groove 101. A secondary platform 2 is connected to the installation groove 101 via a spline. The top surface of the secondary platform 2 has a movable groove 201. The movable groove 201 is connected to the tertiary platform 3 via a spline. A fog cannon body 301 is mounted on the top surface of the tertiary platform 3. A lifting structure is provided inside the installation groove 101. The lifting structure includes a fixed groove 102 located on the bottom surface of the installation groove 101. A screw 103 is rotatably mounted inside the fixed groove 102. A threaded hole is provided on the bottom surface of the secondary platform 2. The screw 103 is threadedly connected to the threaded hole on the bottom surface of the secondary platform 2. A worm gear 104 is fixed on the outer circular wall of the screw 103.

[0023] like Figures 1-4 As shown, in this embodiment, a connecting groove 106 is provided on one side of the primary platform 1, which communicates with the fixing groove 102. A worm gear 105 is rotatably installed inside the connecting groove 106. A drive motor is fixed on one side of the primary platform 1, and the output end of the drive motor is fixed to one end of the worm gear 105. Two sliding holes 202 are provided on the outer circular wall of the secondary platform 2, which are arranged opposite to each other. A connecting belt 203 is slidably installed inside each of the two sliding holes 202. One end of each connecting belt 203 is fixed to the outer circular wall of the tertiary platform 3, and the other end of each connecting belt 203 is fixed to the inner bottom surface of the mounting groove 101. The connecting belt 203 is made of nylon woven material. Through the setting of the lifting structure, the operator starts the drive motor to drive the screw 103 to rotate. The rotation of rod 103 drives the secondary platform 2 to rise. When the secondary platform 2 rises, the other end of the connecting belt 203 is fixed to the bottom of the mounting groove 101, causing the connecting belt 203 to pull the tertiary platform 3 to rise within the movable groove 201. The rise of the tertiary platform 3 increases the height of the fog cannon body 301. When descending, the drive motor reverses, and the screw 103 reverses, driving the secondary platform 2 to descend. The connecting belt 203 releases its pull on the tertiary platform 3, and the tertiary platform 3 descends under its own weight, completing the descent of the fog cannon body 301. This achieves the adjustment of the height of the fog cannon body 301, allowing it to effectively suppress dust in higher areas, expanding the spraying range of the fog cannon body 301, and improving the dust suppression effect of the device.

[0024] like Figures 1-4 As shown, in this embodiment, a plurality of rollers 302 are rotatably arranged inside the sliding hole 202. The plurality of rollers 302 are evenly distributed along the depth direction of the sliding hole 202, and the outer circular wall surfaces of the plurality of rollers 302 are all in contact with the bottom surface of the connecting belt 203. When the connecting belt 203 pulls the three-stage platform 3 to rise and fall, the connecting belt 203 slides in the sliding hole 202. The plurality of rollers 302 make the sliding of the connecting belt 203 smoother, reduce the wear of the connecting belt 203, and improve the service life of the connecting belt 203.

[0025] like Figures 1-4 As shown, in this embodiment, a first gear 4 is rotatably mounted on the top surface of the three-stage platform 3. A second gear 401 meshes with one side of the first gear 4. The top surface of the first gear 4 is fixed to the bottom surface of the fog cannon body 301. A servo motor is fixed on the top surface of the three-stage platform 3. The output end of the servo motor is fixed to the second gear 401. When the fog cannon body 301 is spraying after height adjustment, the operator can start the servo motor to drive the second gear 401 and the second gear 4 to rotate, so that the first gear 4 drives the fog cannon body 301 to rotate, thereby facilitating the operator to control the spraying angle of the fog cannon body 301.

[0026] like Figures 1-4 As shown, in this embodiment, a through hole 5 is provided on the top surface of the three-level platform 3. A connecting shaft 501 is rotatably arranged inside the through hole 5. The top end of the connecting shaft 501 is fixed to the bottom surface of the first gear 4. An anti-detachment ring 502 is fixed on the outer circular wall of the connecting shaft 501. A limiting groove 503 is provided on the inner circular wall of the through hole 5. The anti-detachment ring 502 and the limiting groove 503 are rotatably arranged inside the through hole 501. When the first gear 401 is rotating, the connecting shaft 501 and the anti-detachment ring 502 can prevent the first gear 4 from shifting position during rotation.

[0027] like Figures 1-4 As shown, in this embodiment, a stabilizing groove 6 is provided on the inner bottom surface of the fixing groove 102. The bottom end of the screw 103 is rotatably set inside the stabilizing groove 6. The stabilizing groove 6 can fix the position of the rotating screw 103 and prevent the screw 103 from shifting.

[0028] Working Principle: In use, the operator starts the drive motor, which rotates the screw 103. The rotation of the screw 103 causes the secondary platform 2 to rise. As the secondary platform 2 rises, the other end of the connecting belt 203 is fixed to the bottom of the mounting slot 101, causing the connecting belt 203 to pull the tertiary platform 3 upward within the movable slot 201. The rise of the tertiary platform 3 increases the height of the fog cannon body 301. During descent, the drive motor reverses, and the screw 103 reverses, causing the secondary platform 2 to descend. The connecting belt 203 releases its pull on the tertiary platform 3, which descends under its own weight, completing the descent of the fog cannon body 301. This allows for height adjustment of the fog cannon body 301, enabling it to effectively disperse dust in higher areas. For dust suppression, when the connecting belt 203 pulls the three-stage platform 3 to rise and fall, the connecting belt 203 slides in the sliding hole 202. Several rollers 302 make the sliding of the connecting belt 203 smoother, reduce the wear of the connecting belt 203, and improve the service life of the connecting belt 203. During spraying operations, the operator can start the servo motor to drive the second gear 401 and the second gear 4 to rotate, so that the first gear 4 drives the fog cannon body 301 to rotate, which makes it easier for the operator to control the spraying angle of the fog cannon body 301. When the first gear 401 is rotating, the connecting shaft 501 and the anti-detachment ring 502 can prevent the first gear 4 from shifting position during rotation. The position of the rotating screw 103 can be fixed by the stabilizing groove 6 to prevent the screw 103 from shifting.
