Description

Technical Field

[0001] This invention relates to the field of dust suppression technology, and in particular to a dust suppression device for indoor use in building construction. Background Technology

[0002] At construction sites, the use of various mechanical equipment such as drilling machines, cutting machines, and crushers to cut, grind, or crush building materials generates a large amount of dust. Furthermore, the movement and stacking of cement, sand, lime, and other loose materials without proper covering or control measures also produces dust. Dust poses potential hazards to human health and the environment. Inhaling large amounts of dust can lead to respiratory illnesses such as respiratory irritation, allergic reactions, asthma exacerbations, and pneumoconiosis. High dust concentrations in the air can also reduce visibility and increase the risk of accidents. Therefore, implementing effective dust control measures is crucial for protecting the health of construction workers and maintaining environmental quality.

[0003] Chinese invention patent CN117983003A discloses a dust suppression device for building construction, which sprays a mixture of water and surfactant through a water spray assembly. This allows dust to come into contact with the mixture, increasing the contact area and adhesion between the water and dust, thereby improving the dust suppression effect. However, the fixed nozzle position limits the spray range and makes it difficult to adapt to the constantly changing dust distribution at the construction site, potentially preventing the water mist from effectively covering key dust-generating areas. Chinese invention patent CN118384639A discloses an automatic dust suppression device for building construction sites, which uses intermittent multi-directional spraying at mid-to-high levels and continuous dust collection at low levels to suppress dust. Dust control, low-level continuous dust collection can attract surrounding dust and improve the dust reduction efficiency of atomized spraying. However, it still has shortcomings in use. Its water mist spraying radiates outward from the device as the center. To achieve a better dust reduction effect, the device needs to be moved to the central area where dust is generated, i.e., the construction area. The water mist continuously sprayed by the device may affect the construction work of on-site operators, especially when the water mist is sprayed directly at the construction workers, which may interfere with their vision and work. Although the water mist radiating outward from the device as the center can effectively reduce the dust concentration in the central part of the construction area, it cannot effectively isolate the dust, causing the dust in the edge of the construction area to easily spread outward to the non-construction area. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a dust suppression device for indoor use in building engineering that can freely adjust the direction of water mist spraying and isolate dust.

[0005] Technical Solution: A dust suppression device for indoor use in building construction includes a cabinet with a flip-top and a water storage tank placed inside the cabinet. At least two sliders are slidably mounted on the top of the cabinet, and a corrugated pipe connects the sliders to the water storage tank. The device also includes a protective pipe rotatably mounted on the top of the sliders. A mounting seat with a limit bolt is fixedly mounted on the top of the protective pipe. A spray pipe with an atomizing nozzle mounted on the top is rotatably mounted on the mounting seat. The limit bolt restricts the rotation of the spray pipe. A water delivery hose extending downwards into the water storage tank is connected to the bottom of the atomizing nozzle. The device further includes a support platform fixedly mounted on the top of the cabinet. A sliding plate and a toothed plate are slidably mounted on the support platform. Two sliding rods symmetrically rotate and penetrate the sliding plate on the side wall of the toothed plate. A spur gear meshes with the teeth of the toothed plate at the lower part of the protective pipe. A cylinder with its movable end fixedly connected to the sliding plate is fixedly mounted on the support platform.

[0006] To further explain, the protective tube includes an inner tube and an outer tube sleeved on the inner tube. The inner tube is rotatably connected to the slider. The spur gear is disposed on the inner tube portion of the protective tube. The mounting base is disposed at the top end of the outer tube portion of the protective tube.

[0007] Further explanation: It also includes two top blocks I symmetrically fixedly disposed on the side wall of the toothed plate and an elastic element disposed between the toothed plate and the slide plate. The slide rod passes through the top block I and rotates with the top block I. Top blocks II are also fixedly disposed on the two slide rods. The top block I and the top block II are in contact.

[0008] To further explain, the end of the top block I facing the top block II is set to be concave, and the end of the top block II facing the top block I is set to be convex, and the convex part and the concave part fit together.

[0009] To further explain, it also includes a limiting frame that is slidably mounted on the cabinet. The lower part of the limiting frame is provided with insert rods at equal intervals, and the insert rods can be inserted into the slider and limit the slider.

[0010] Further explanation: It also includes a guide rail fixedly mounted on the upper surface of the cabinet and a slide block slidably mounted in the guide rail. A servo motor with a bushing fixed to the end of the output shaft is mounted on the slide block, and a flat key shaft is slidably mounted in the bushing. A slide groove is opened on the upper part of the limiting frame, and a toggle member is provided in the slide groove. The toggle member can slide along the slide groove and can also rotate in the slide groove. The front and rear ends of the toggle member are fixedly connected to the flat key shaft and the slide rod, respectively.

[0011] Further explanation: It also includes lead screws rotatably mounted on the left and right side walls of the cabinet and lifting frames rotatably connected to the top ends of the two lead screws, the lifting frames abutting against the bottom end of the outer tube of the protective tube.

[0012] To further explain, it also includes an exhaust fan installed at the bottom of the cabinet and two dust collection frames connected to the exhaust fan via pipes.

[0013] The beneficial effects are as follows: This invention, through a sliding slider and protective tube, and a rotatable and adjustable spray pipe and atomizing nozzle, uses a cylinder to drive the sliding plate to move, which in turn drives the toothed plate to move and mesh with a spur gear, causing the protective tube to rotate. This allows for flexible adjustment of the spray direction and position according to different needs of the construction area, forming a water mist wall that can isolate dust, improving dust suppression and preventing dust from spreading to non-construction areas. The inner and outer tube design of the protective tube allows for variations in spray height, adapting to different construction environments and increasing the equipment's applicability. The concave-convex structure design of top blocks I and II, when the protruding and recessed parts do not match, holds the toothed plate in place, and with the spur gear, fixes the angle of the protective tube. A limit frame locks the slider position, ensuring that the water mist spray angle remains constant during operation, thus guaranteeing spray position accuracy. The servo motor and key shaft design simplify operation and reduce the need for manual intervention. The lifting frame allows for easy adjustment of the protective tube height, further enhancing the overall performance of the equipment. Attached Figure Description

[0026] Please see Figure 1 , Figure 2 and Figure 9 This invention provides an indoor dust suppression device for building construction, comprising a cabinet 1 with a flip-top cover 11 installed on the front and a water storage tank 2 placed inside the cabinet 1. (See attached image) Figure 2 Two sliders 12 are slidably mounted on the top of the cabinet 1, and a corrugated pipe 21 connects the sliders 12 to the water tank 2. The sliders 12 can slide on the top of the cabinet 1, and the corrugated pipe 21 deforms accordingly as the sliders 12 slide, ensuring that there is always a channel for water to flow between the sliders 12 and the water tank 2; see Figure 1A protective tube 3 is provided on the top of the slider 12. The protective tube 3 consists of an inner tube 31 and an outer tube 32 sleeved on the inner tube 31. The inner tube 31 is rotatably connected to the slider 12 and connected to the corresponding corrugated pipe 21. A hollow mounting base 4 is fixedly provided on the top of the outer tube 32. A spray pipe 41 is rotatably connected to the mounting base 4, and a limit bolt 42 is rotatably connected to the side wall of the mounting base 4. After the angle of the spray pipe 41 is adjusted by rotation, the limit bolt 42 can be tightened clockwise to limit the spray pipe 41. An atomizing nozzle 43 is installed on the top of the spray pipe 41. When the spray pipe 41 is rotated, the angle of the atomizing nozzle 43 will also change. When the spray pipe 41 is kept vertical, the atomizing nozzle 43 can spray water mist outward with itself as the center. When the spray pipe 41 is oriented in a certain direction, the atomizing nozzle 43 can form a water mist wall on the vertical plane, which can both adsorb and treat dust and prevent dust diffusion. (See reference...) Figure 9 The bottom of the atomizing nozzle 43 is connected to a water supply hose 44, which passes through the nozzle 41, the protective pipe 3 and the corrugated pipe 21 in sequence, and extends downward into the water storage tank 2.

[0027] In this embodiment of the invention, depending on the specific conditions of the construction site, the two sliders 12 are moved away from or closer to each other, and the spray pipe 41 is rotated so that the spray pipe 41 and the atomizing nozzle 43 face the construction area. The atomizing nozzle 43 is activated to generate a water mist wall, which separates the construction area from the non-construction area while treating dust. If there is no distinction between the construction area and the non-construction area inside the building, the spray pipe 41 can also be kept vertical, with the atomizing nozzle 43 as the center, to spray water mist outward.

[0028] Please see Figure 3 and Figure 4 In this embodiment of the invention, a support platform 5 is also fixedly installed on the front of the upper surface of the cabinet 1. A slide plate 51 and a toothed plate 52 are slidably installed on the support platform 5. Two sliding rods 521 that pass through the slide plate 51 are symmetrically rotatably installed on the front side wall of the toothed plate 52. With the connection of the sliding rods 521, the slide plate 51 and the toothed plate 52 can move to the left or right synchronously. A spur gear 53 is fixedly installed on the inner tube 31 of the two protective tubes 3. The spur gear 53 meshes with the teeth on the toothed plate 52. A cylinder 54 is also installed on the right side of the support platform 5. The movable end of the cylinder 54 is fixedly connected to the right end of the slide plate 51. When the cylinder 54 is activated, its movable end is extended, and the slide plate 51 and the toothed plate 52 will be pushed to slide to the left. The toothed plate 52 then drives the spur gear 53 to rotate clockwise, and the inner tube 31 rotates clockwise accordingly, so that the orientation of the nozzle 41 and the atomizing nozzle 43 changes accordingly.

[0029] Please see Figure 5 and Figure 6In this embodiment of the invention, two top blocks I6 are symmetrically fixed on the front sidewall of the toothed plate 52. A slide rod 521 is inserted into the top block I6 and rotates with it. Top blocks II61 are also fixed on the two slide rods 521. The front end of the top block I6 is recessed, and the rear end of the top block II61 is protruding. The recessed end of the top block I6 and the protruding end of the top block II61 are in contact and fit together. The toothed plate 52 and the slide plate 51 are also provided with elastic elements 62, which are springs. The invention also includes a limiting frame 7 slidably mounted on the cabinet 1. Insert rods 71 ​​are evenly spaced at the lower part of the limiting frame 7. The insert rods 71 ​​can be inserted into the slider 12 and limit the slider 12 to ensure that the slider 12 cannot slide freely when the equipment is working. Initially, the protruding end of the top block II61 is not embedded in the recessed end of the top block I6. At this time, the top block I6 and the top block II61 are in contact. Next, the toothed plate 52 and the spur gear 53 are in a meshing state, and the elastic element 62 is in a stretched state. At this time, if the moving end of the cylinder 54 remains stationary, the spur gear 53 and the inner tube 31 cannot rotate, and the orientation of the nozzle 41 and the atomizing nozzle 43 remains fixed, which can ensure the stability of the equipment during operation. If it is necessary to adjust the position of the slider 12 and the nozzle 41 and the atomizing nozzle 43, the limit bracket 7 must first be moved to disengage the insert rod 71 from the slider 12. At this time, due to the restriction of the toothed plate 52, the slider 12 still cannot slide freely. The slide rod 521 needs to be rotated until the protruding end of the top block II 61 is embedded in the recessed end of the top block I 6. At this time, due to the engagement of the two, the toothed plate 52 has space to move forward. When the elastic element 62 returns to its original state, it will pull the toothed plate 52 forward, thereby disengaging the toothed plate 52 from the spur gear 53. At this time, the position of the slider 12 can be freely adjusted.

[0030] Please see Figure 5 and Figure 7 In this embodiment of the invention, a guide rail 8 is also installed on the upper surface of the cabinet 1. A slide block 81 is slidably arranged on the guide rail 8. A servo motor 82 is installed on the top of the slide block 81. A bushing 83 is fixedly connected to the end of the output shaft of the servo motor 82. A flat key shaft 84 is slidably arranged inside the bushing 83. A spring is provided between the flat key shaft 84 and the bushing 83. The flat key shaft 84 can not only rotate synchronously with the bushing 83, but also slide inside the bushing 83. A slide groove 72 is provided on the upper part of the limit frame 7. A toggle member 85 is provided inside the slide groove 72. The toggle member 85 can not only slide along the slide groove 72, but also rotate inside the slide groove 72. The front and rear ends of the toggle member 85 are fixedly connected to the flat key shaft 84 and the slide rod 521 located on the right, respectively.

[0031] In this embodiment of the invention, the servo motor 82 drives the slide bar 521 to rotate, thereby enabling the top block II 61 and the top block I 6 to rotate and connect without manual rotation. After the top block II 61 and the top block I 6 are connected, when the toothed plate 52 moves forward, it will push the actuating member 85 forward through the slide bar 521, thereby pushing the limit frame 7 forward and disengaging the insertion rod 71 from the slider 12, further simplifying the operation of the equipment. In addition, the guide rail 8 and the slide base 81 are designed to slide, and the actuating member 85 can slide in the slide groove 72. This ensures that when the cylinder 54 pushes the slide plate 51 and the toothed plate 52 to move left and right, there will be no obstruction.

[0032] Please see Figure 2 and Figure 8 In this embodiment of the invention, screw rods 9 are rotatably installed on the left and right side walls of the cabinet 1. The top ends of the two screw rods 9 are rotatably connected to a lifting frame 91. The lifting frame 91 abuts against the bottom end of the outer tube 32 of the protective tube 3. Rotating the screw rods 9 clockwise can lift the lifting frame 91, thereby raising the outer tube 32 of the protective tube 3 upward, so that the atomizing nozzle 43 is in a higher position, which can treat the dust at a higher position. It also includes an exhaust fan 10 installed at the bottom of the cabinet 1 and two pipes connected to the exhaust fan 10. Starting the exhaust fan 10 can suck up the dust deposited on the construction ground, further reducing the dust concentration in the construction area.
