Description

Technical Field

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

[0002] During construction, a large amount of dust is generated in the construction area, posing a threat to the health of workers and surrounding residents. Therefore, it is necessary to reduce dust in the construction area.

[0003] When suppressing dust in construction areas, water mist is typically sprayed using a fog cannon. Since the fog cannon needs to cover a large area, its position needs to be adjusted during spraying. Because the water pipe connected to the fog cannon is not easily adjusted with its position, water is sprayed onto its surface, causing a large number of water droplets to adhere to it. Since these droplets may contain various impurities, if they are not removed, they can easily produce unpleasant odors and corrode the pipe surface after it is retracted, thus reducing its lifespan. Summary of the Invention

[0004] This invention provides a dust suppression device for green building construction. When the water pipe is being rolled up, the water suction component absorbs the moisture on the surface of the water pipe, making it easy to remove water droplets adhering to the surface of the water pipe. This solves the problem mentioned in the background technology that if water droplets are not treated on the surface of the water pipe, impurities in the water after the water pipe is rolled up will not only easily produce odors, but also cause corrosion to the surface of the water pipe, thereby reducing the service life of the water pipe.

[0010] As an optional solution of the dust suppression device for green building construction described in this invention, the adjusting component includes a second gear rotatably disposed inside the sliding column, a first rack meshing with the second gear fixed at the end of the core rod, and a second rack meshing with the second gear fixed on the surface of the lifting plate, wherein the first rack and the second rack are misaligned.

[0011] As an optional embodiment of the dust suppression device for green building construction described in this invention, the adjusting component includes a first hydraulic oil tank and a second hydraulic oil tank opened inside the sliding column. A first piston plate is slidably disposed in the first hydraulic oil tank, and an abutment rod is fixed on the first piston plate.

[0014] As an optional solution of the dust suppression device for green building construction described in this invention, a support plate is fixed to the surface of the side plate, a second servo motor is fixed to the top of the support plate, a reciprocating screw is fixed to the output end of the second servo motor, the two ends of the reciprocating screw are rotatably connected to the support plate and the side plate respectively, a moving plate is threaded onto the reciprocating screw, a horizontal plate is fixed to the end of the moving plate, and the positioning seat and the limiting plate are fixed to the horizontal plate.

[0015] The present invention has the following beneficial effects: 1. This dust suppression device for green building construction uses a water-absorbing component to absorb water droplets on the surface of the water pipe during the pipe winding process, reducing the impact of water droplets and impurities on the pipe surface. The water-absorbing component rotates while absorbing water, improving the absorption effect. Furthermore, the rotation of the water-absorbing component drives a first sliding rod to slide along a first sliding groove. The first sliding rod drives a first limiting ball to slide along a first track groove, allowing the first sliding rod to reciprocate left and right. This reciprocating motion of the first sliding rod drives a squeezing plate to periodically squeeze the absorbent, facilitating the removal of moisture from the absorbent component and further improving its absorption effect.

[0016] 2. In this dust suppression device for green building construction, when the water-squeezing plate squeezes the water-absorbing component, the first sliding rod drives the core rod to move synchronously. The core rod drives the second limiting ball to slide along the second track groove. When the second limiting ball slides to the third leftward part of the second track groove, the second limiting ball can drive the core rod to move horizontally relative to the first sliding rod. Through the action of the adjusting component, the core rod can drive the lifting column to move downward, which in turn drives the connecting rod to move downward. The connecting rod drives the water-squeezing plate to move downward, so that the water-squeezing plate squeezes the water-absorbing component from top to bottom. This not only increases the fullness of the water-absorbing component being squeezed, but also facilitates the squeezing of water from the inside out of the water-absorbing component, reducing the situation where the squeezed water re-adheres to the surface of the water pipe, and further improving the water absorption effect.

[0017] 3. In this dust suppression device for green building construction, when the water-squeezing plate moves downward to squeeze the water-absorbing component, the downward movement of the lifting column fills the fourth hydraulic oil tank with hydraulic oil from the third hydraulic oil tank. This allows the fourth piston plate to drive the pull rod to move, which in turn pulls the extension plate to move. The extension plate extends beyond the inside of the water-squeezing plate, ensuring that the end of the extension plate always moves along the end of the water-absorbing component. Through the cooperation of the water-squeezing plate and the extension plate, the range of water being squeezed by the water-absorbing plate is increased, and the squeezing dead angle is reduced. This improves the adequacy of water drainage by the water-absorbing component and further enhances its water absorption effect. Attached Figure Description

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.

[0034] Example 1, please refer to Figures 1-14 A dust suppression device for green building construction includes a fog cannon 1, a side plate 2 fixed on the surface of the fog cannon 1, a winding machine 3 for winding a water pipe 46 fixed on the side plate 2, a positioning seat 4 that can be raised and lowered on the outside of the water pipe 46, an installation seat 5 rotatably provided on the inside of the positioning seat 4, and a water-absorbing component 6 fixed on the inner surface of the installation seat 5. A positioning plate 7 is provided on the outer side of the mounting base 5, which rotates synchronously with the water-absorbing component 6. A squeezing plate 8 is slidably provided on the inner side of the positioning plate 7. A limiting plate 9 is provided on the outer side of the positioning plate 7, which moves synchronously with the positioning base 4. A first sliding groove 10 is provided on the limiting plate 9. A first sliding rod 11 is slidably provided in the first sliding groove 10. The squeezing plate 8 squeezes the water-absorbing component 6 through the first sliding rod 11 inside the first sliding groove 10, causing the water-absorbing component 6 to drain water. A toothed ring 12 is fixed on the outer surface of the mounting base 5. A rotating groove 13 for the toothed ring 12 to rotate is opened inside the positioning base 4. A first servo motor 14 is fixed on the inner wall of the rotating groove 13. A first gear 15 that meshes with the toothed ring 12 is fixed at the output end of the first servo motor 14. A second slide rod 16 is fixed on the outer surface of the toothed ring 12. The end of the second slide rod 16 is fixed to the positioning plate 7, and the second slide rod 16 is slidably connected to the positioning base 4. A strip block 17 is fixed on the surface of the positioning plate 7. A second sliding groove 18 is opened on the surface of the strip block 17. A sliding column 19 is slidably arranged in the second sliding groove 18. A connecting rod 20 is arranged between the sliding column 19 and the water squeezing plate 8. The end of the first sliding rod 11 is fixed to the sliding column 19. A first limiting ball 21 is fixed to the end of the first sliding rod 11. A first track groove 22 for the first limiting ball 21 to slide is opened inside the first sliding groove 10. A support plate 41 is fixed to the surface of the side plate 2. A second servo motor 42 is fixed to the top of the support plate 41. A reciprocating screw 43 is fixed to the output end of the second servo motor 42. The two ends of the reciprocating screw 43 are rotatably connected to the support plate 41 and the side plate 2, respectively. A moving plate 44 is threaded onto the reciprocating screw 43. A horizontal plate 45 is fixed to the end of the moving plate 44. The positioning seat 4 and the limiting plate 9 are fixed to the horizontal plate 45.

[0035] In this technical solution, during dust suppression in construction, one end of the water pipe 46 is first connected to a water source. The water pipe 46 is then unwound by the winding machine 3 to increase its length, making it easier for the fog cannon 1 to move to different locations. The fog cannon 1 then sprays water onto the construction site to suppress dust. The fog cannon 1 can spray water, and the winding machine 3 can wind and unwind the water pipe 46. Both the fog cannon 1 and the winding machine 3 are existing technologies and are not the innovations of this application, so they will not be described in detail. In this application, the positioning seat 4, mounting seat 5, water-absorbing component 6, positioning plate 7, water-squeezing plate 8, and limiting plate 9 are all designed as semi-circular structures, and each is configured in two sets. The two sets of positioning seats 4, mounting seats 5, water-absorbing components 6, positioning plates 7, water-squeezing plates 8, and limiting plates 9 can form a complete circular structure. When winding the water pipe 46, the water pipe 46 is first placed between the two sets of water-absorbing components 6. Then, the second servo motor 42 drives the reciprocating screw 43 to rotate. The reciprocating screw 43 drives the moving plate 44 to move. The moving plate 44 drives the horizontal plate 45 to move. The horizontal plate 45 drives the positioning seat 4 and the limiting plate 9 to move. The positioning seat 4 drives the mounting seat 5 and the positioning plate 7 to move. The mounting seat 5 drives the water-absorbing component 6 to move. The positioning seat 4, mounting seat 5, water-absorbing component 6, positioning plate 7, squeezing plate 8, and limiting plate 9 are connected to form a complete circular structure. At this time, the two sets of water-absorbing components 6 wrap around the water pipe 46. When the winding machine 3 winds up the water pipe 46, the water-absorbing components 6 can absorb the moisture on the surface of the water pipe 46, increasing the dryness of the surface of the water pipe 46. In order to increase the water absorption effect of the water-absorbing components 6 on the surface of the water pipe 46, when the water pipe 46 is wound up, the first servo motor 14 drives the first gear 15 to rotate, the first gear 15 drives the gear ring 12 to rotate, the gear ring 12 drives the mounting seat 5 to rotate, and the mounting seat 5 drives the water-absorbing component 6 to rotate, so that the water-absorbing component 6 can rotate while absorbing water, resulting in a better water absorption effect. The absorbent component 6 can be an absorbent sponge. After the absorbent component 6 absorbs water, if the water inside the absorbent component 6 cannot be discharged in time, the absorbent component 6 will have reduced absorbency, thus reducing the absorbency effect. Therefore, when the absorbent component 6 rotates, the toothed ring 12 rotates, which drives the second slide rod 16 to rotate. The second slide rod 16 drives the positioning plate 7 to rotate. The positioning plate 7 drives the strip block 17 to rotate. The strip block 17 drives the sliding column 19 to rotate. The sliding column 19 drives the first slide rod 11 to slide along the first slide groove 10. The first slide rod 11 drives the first limiting ball 21 to slide along the first track groove 22, so that the first slide rod 11 pushes the sliding column 19 to move. The sliding column 19 drives the squeezing plate 8 to move towards the absorbent component 6, so that the squeezing plate 8 squeezes the absorbent component 6 and squeezes out the water inside the absorbent component 6. In this technical solution, the first trajectory groove 22 includes a first translation part 221, a first left translation part 222, a second translation part 223, and a first right translation part 224 that are connected together. The first left translation part 222 is arranged as follows: Figure 3 At position a shown, the first left-moving part 222 is located inside the lower limiting plate 9. Both sides of the absorbent 6 are equipped with squeezing plates 8, and their working principles are the same. The following explanation uses the right-side squeezing plate 8 as an example. Specifically, when the first sliding rod 11 drives the first limiting ball 21 to slide from the first left-moving part 222 of the first translation part 221 and along the first left-moving part 222, the first limiting ball 21 drives the first sliding rod 11 to move to the left. The first sliding rod 11 drives the sliding column 19 to move to the left along the second sliding groove 18. The sliding column 19 pushes the squeezing plate 8 to the left through the connecting rod 20, causing the squeezing plate 8 to squeeze the absorbent 6. The water inside the absorbent 6 is squeezed out. Then the first limiting ball 21 slides along the second translation part 223, and the squeezing plate 8 squeezes the absorbent 6 to the deepest position. When the first limiting ball 21 slides along the first right translation part 224, the first limiting ball 21 drives the first sliding rod 11 to reset to the right. The first sliding rod 11 drives the sliding column 19 to reset. The sliding column 19 drives the squeezing plate 8 to reset to the right through the connecting rod 20, thus completing the squeezing work. The squeezing work starts from point a and ends at most when rotating one-eighth of a circle. In addition, the squeezing work is carried out at a lower point a. By utilizing the gravity of the water, the water at the squeezing point can fall directly out and the squeezing effect is better. In this technical solution, the mounting base 5 is designed with a mesh structure. When the water-absorbing component 6 is squeezed, the squeezed water can be easily discharged through the mesh on the mounting base 5, reducing the problem of inconvenient discharge of squeezed water. In addition, a limiting groove 47 is opened inside the mounting base 5, and a limiting block 48 is fixed on the surface of the toothed ring 12. The limiting block 48 is slidably disposed in the limiting groove 47. When the toothed ring 12 rotates, it can drive the limiting block 48 to slide along the limiting groove 47, making the rotation of the toothed ring 12 more stable. Furthermore, the limiting groove 47 limits the limiting block 48, so that the toothed ring 12 will not separate from the mounting base 5.

[0036] In Example 2, when the squeezing plate 8 squeezes and drains water from the absorber 6, if the squeezing plate 8 and the absorber 6 have the same cross-section, the squeezed water will be discharged along the periphery of the absorber 6. Therefore, the water squeezed out from above the absorber 6 will re-adhere to the surface of the water pipe 46, increasing the moisture content of the water pipe 46 surface. However, if a squeezing plate 8 with a smaller cross-section than the absorber 6 is used, insufficient squeezing may occur. To address this problem, this example is an improvement based on Example 1. For details, please refer to... Figures 1-14The first sliding rod 11 has a core rod 23 that can move back and forth. The sliding column 19 has a slide rail 24 for the connecting rod 20 to slide. The sliding column 19 has a lifting groove 25 inside. The lifting plate 26 is slidably arranged in the lifting groove 25. The end of the connecting rod 20 is fixed to the lifting plate 26. An adjustment component 27 is provided between the core rod 23 and the lifting plate 26. The adjustment component 27 drives the lifting plate 26 to rise and fall by moving the core rod 23 left and right. The end of the core rod 23 is fixed with a second limiting ball 28, and the inside of the limiting plate 9 is provided with a second track groove 29 for the second limiting ball 28 to slide. The adjusting assembly 27 includes a second gear 271 rotatably disposed inside the sliding column 19, a first rack 272 that meshes with the second gear 271 fixed at the end of the core rod 23, and a second rack 273 that meshes with the second gear 271 fixed on the surface of the lifting plate 26, with the first rack 272 and the second rack 273 being misaligned.

[0037] In this technical solution, such as Figure 12 As shown, the cross-section of the squeezing plate 8 in this application is smaller than that of the water-absorbing member 6. When the squeezing plate 8 squeezes and drains water from the water-absorbing member 6, it only squeezes a small portion of the member, reducing the amount of water squeezed out and thus reducing the amount of water that is squeezed out and re-attaches to the surface of the water pipe 46. Because the squeezing plate 8 is small, it can only squeeze a small portion of the water-absorbing member 6, which will result in insufficient squeezing and prevent the water inside the water-absorbing member 6 from being fully discharged. Therefore, the second trajectory groove 29 includes a third translation part 291, a second left translation part 292, a third left translation part 293, and a fourth translation part 294 that are connected together. The second right-shifting section 295 and the third right-shifting section 296, when the first limiting ball 21 slides along the first translation section 221 and the first left-shifting section 222, the second limiting ball 28 slides along the third translation section 291 and the second left-shifting section 292 of the second track groove 29. The first sliding rod 11 and the core rod 23 move synchronously, maintaining their relative positions. When the first limiting ball 21 slides along the second translation section 223, the second limiting ball 28 first slides along the third left-shifting section 293, causing the second limiting ball 28 to move to the left relative to the first limiting ball 21, thereby causing the core rod 23 to move to the left relative to the first sliding rod 11. Figure 9 and Figure 10 As shown, the core rod 23 moves to the left, causing the first rack 272 to move to the left. The first rack 272 drives the second gear 271 to rotate. The rotation of the second gear 271 drives the second rack 273 to move downward. The second rack 273 drives the lifting plate 26 to move downward. The lifting plate 26 drives the connecting rod 20 to move downward. The connecting rod 20 drives the squeezing plate 8 to move downward. Figure 12As shown, the water-squeezing plate 8 moves downward, so that the water-squeezing plate 8 squeezes the water-absorbing member 6 from top to bottom. This not only increases the fullness of the water-absorbing member 6 being squeezed, but also makes it easier to squeeze the water inside the water-absorbing member 6 from the inside out, reducing the situation where the squeezed water re-adheres to the surface of the water pipe 46. In this technical solution, by misaligning the first rack 272 and the second rack 273, collisions between the first rack 272 and the second rack 273 during movement are avoided. Furthermore, the first rack 272 can pass through the sliding column 19 during leftward movement, and the position where the first rack 272 passes through the sliding column 19 is also misaligned with the slide rail 24, so that the first rack 272 will not affect the lifting and lowering movement of the connecting rod 20.

[0038] Example 3: This example presents another technical solution for adjusting component 27. For details, please refer to [link / reference]. Figures 1-14 The adjusting component 27 includes a first hydraulic oil groove 274 and a second hydraulic oil groove 275 opened inside the sliding column 19. A first piston plate 276 is slidably arranged in the first hydraulic oil groove 274. An abutment rod 277 is fixed on the first piston plate 276. An abutment block 278 that abuts against the abutment rod 277 is fixed at the end of the core rod 23. The abutment block 278 is slidably arranged in the sliding column 19. A second piston plate 279 is elastically arranged in the second hydraulic oil groove 275. A first transmission rod 2710 is fixed between the second piston plate 279 and the lifting plate 26.

[0039] In this technical solution, the first hydraulic oil tank 274 and the second hydraulic oil tank 275 are connected, and a first spring 2711 is fixed between the second piston plate 279 and the inner wall of the second hydraulic oil tank 275; Figure 14 As shown, when the core rod 23 moves to the left relative to the first sliding rod 11, the core rod 23 drives the abutment block 278 to move to the left, causing the abutment block 278 to abut against the abutment rod 277, causing the abutment rod 277 to move upward. The abutment rod 277 drives the first piston plate 276 to move upward, filling the hydraulic oil inside the first hydraulic oil tank 274 into the second hydraulic oil tank 275, causing the second piston plate 279 to move downward. At the same time, the first spring 2711 is stretched, causing the first spring 2711 to store force. The downward movement of the second piston plate 279 drives the first transmission rod 2710 to move downward. The first transmission rod 2710 drives the lifting plate 26 to move downward, causing the lifting plate 26 to drive the connecting rod 20 to move downward. The connecting rod 20 drives the squeezing plate 8 to move downward, causing the squeezing plate 8 to squeeze the water-absorbing component 6 from top to bottom.

[0040] In Example 4, because the cross-section of the squeezing plate 8 is smaller than that of the suction member 6, when the squeezing plate 8 squeezes water from the inside out along the suction member 6, the end of the squeezing member cannot reach the end of the suction member 6, resulting in a squeezing dead angle and reducing the squeezing drainage effect. To address this problem, this example is an improvement based on Example 2 or Example 3. For details, please refer to... Figures 1-14 An extension plate 30 is slidably provided at the end of the dewatering plate 8. A pull rod 31 is fixed on the surface of the extension plate 30. A moving groove 32 is provided inside the positioning plate 7. A longitudinal plate 33 is fixed at the end of the pull rod 31. The longitudinal plate 33 is elastically disposed in the moving groove 32. The pull rod 31 pulls the extension plate 30 out of the dewatering plate 8 by retracting into the moving groove 32. The sliding column 19 has a third hydraulic oil groove 34 inside, and a third piston plate 35 is slidably arranged inside the third hydraulic oil groove 34. A second transmission rod 36 is fixed between the third piston plate 35 and the lifting plate 26. The positioning plate 7 has a fourth hydraulic oil groove 37 inside, and an oil guide pipe 38 is arranged between the fourth hydraulic oil groove 37 and the third hydraulic oil groove 34. A fourth piston plate 39 is slidably arranged inside the fourth hydraulic oil groove 37, and a third transmission rod 40 is fixed between the fourth piston plate 39 and the longitudinal plate 33.

[0041] In this technical solution, when the dewatering plate 8 moves downward, the lifting plate 26 drives the third piston plate 35 to move downward via the second transmission rod 36. The downward movement of the third piston plate 35 causes the hydraulic oil inside the third hydraulic oil tank 34 to be pumped into the fourth hydraulic oil tank 37 through the oil guide pipe 38. Figure 13 As shown, at this time, the fourth piston plate 39 moves to the right, causing the fourth piston plate 39 to drive the third transmission rod 40 to move to the right. The third transmission rod 40 drives the longitudinal plate 33 to move to the right. A second spring 49 is fixed between the longitudinal plate 33 and the inner wall of the positioning plate 7. The longitudinal plate 33 moves to the right and stretches the second spring 49, causing the second spring 49 to store force. At the same time, the longitudinal plate 33 moves to the right and drives the pull rod 31 to move to the right. The pull rod 31 drives the extension plate 30 to move to the right. Through the extension plate 30, when the squeezing plate 8 moves downward, the extension plate 30 extends, so that the end of the extension plate 30 always moves horizontally along the end of the water suction member 6, which facilitates the squeezing of the entire part of the water suction member 6, thereby reducing the squeezing dead angle and further improving the drainage effect of the water suction member 6. In this technical solution, the extension plate 30 is set as a spring sheet with a certain elasticity. When the pull rod 31 pulls the extension plate 30 to the right and moves the extension plate 30 out of the interior of the dewatering plate 8, the elasticity of the extension plate 30 allows the extension plate 30 to produce a certain arc deformation, thus avoiding jamming.
