Technical Field

[0001] This utility model relates to the field of dust suppression technology in building construction, specifically a dust suppression device for dust generated during building construction. Background Technology

[0002] Construction dust is a significant source of urban air pollution. Large amounts of particulate matter are generated during various stages of construction, including earthwork excavation, foundation construction, material transportation, concrete mixing, and building demolition. This dust not only contains ordinary soil particles but may also contain chemical components such as cement, lime, and ceramic dust, causing serious pollution to the construction site and its surrounding environment.

[0003] Currently, common dust suppression measures at construction sites mainly include traditional methods such as water truck spraying, fixed spray systems, and dust netting. While water trucks are convenient to move, they suffer from significant water waste, short-lasting dust suppression effects, and high operating frequency. Especially in hot and dry weather conditions, water evaporates rapidly, requiring repeated spraying to maintain the dust suppression effect. Fixed spray systems, although capable of continuous operation, have limited coverage, often require extensive piping installation, resulting in high costs, and are difficult to reposition flexibly according to the construction progress.

[0004] Therefore, this utility model provides a dust suppression device for construction dust to solve the above-mentioned problems. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1-4 As shown, this utility model provides a dust suppression device for construction dust, including a movable base 1, a lifting mechanism 2 on the top of the movable base 1, a platform 3 on the top of the lifting mechanism 2, a transfer mechanism 4 on the top of the platform 3, and a dust suppression mechanism 5 on the top of the transfer mechanism 4. The dust suppression mechanism 5 includes a water storage pan 501. Multiple water outlet pipes 502 are equidistantly arranged on the top of the water storage pan 501. The bottom end of the water outlet pipes 502 is located inside the water storage pan 501. One end of the water outlet pipe 502 is detachably connected to a nozzle 503. An atomizing plate 504 is arranged inside the nozzle 503. A toothed ring 505 is fixedly connected to the outer wall of the water storage pan 501. A gear 506 is meshed with the outer wall of the toothed ring 505. The inner wall of the gear 506 is connected to the output end of the first motor 507. By setting up a lifting mechanism 2, a transfer mechanism 4, and a rotatable dust suppression mechanism 5, the three-dimensional adjustable spray height, horizontal position, and spray angle are realized. The operating position can be flexibly adjusted according to the distribution of dust sources at the construction site, which significantly improves the dust suppression coverage and precise dust suppression capability.

[0018] The transfer mechanism 4 includes a slide 401, which is formed on the top of the table panel 3. A slider 402 is slidably connected to the inner wall of the slide 401. A lead screw 403 is threadedly connected to the inner wall of the slider 402. The outer wall of the lead screw 403 is rotatably connected to the inner wall of the table panel 3. One end of the lead screw 403 passes through the table panel 3 and is connected to the output end of the second motor 404. The second motor 404 is fixedly connected to one end of the table panel 3.

[0019] The other end of the table panel 3 is fixedly connected to a bearing seat 7, and a bearing 6 is installed inside the bearing seat 7. The bearing seat 7 is rotatably connected to the lead screw 403 through the bearing 6. By setting the bearing seat 7 and the bearing 6, the lead screw 403 can play an auxiliary support role during rotation, ensuring the stability of the lead screw 403 rotation. At the same time, it can also reduce the friction generated when the lead screw 403 rotates, ensuring the efficiency of the lead screw 403 rotation and avoiding the situation of rotation jamming.

[0020] The lifting mechanism 2 includes two guide frames 201, both of which are fixedly connected to the top of the movable base 1. A guide block 202 is slidably connected to the inner wall of the guide frame 201. The top of the guide block 202 is fixedly connected to the bottom of the platform 3. A plurality of first lifting cylinders 203 are fixedly connected to the top of the movable base 1. The top of the first lifting cylinder 203 is connected to the bottom of the platform 3.

[0021] The bottom of the mobile base 1 is equipped with walking wheels 8 and a driver that drives the walking wheels 8 to move. The top of the platform 3 is provided with a guide groove 9. The platform 3 is slidably connected to the moving block 10 through the guide groove 9. The top of the moving block 10 is fixedly connected to the bottom of the first motor 507. With the mobile base 1, walking wheels 8 and driver, it has good mobility and can be quickly transferred to different work areas to adapt to changes in the construction progress. It solves the problem of complex installation and difficulty in relocation of fixed spraying systems.

[0022] A water tank 11 is fixedly connected to the top of the mobile base 1, and a rotary joint 12 is provided on the top of the water storage pan 501. A water pump is installed inside the water tank 11. The water tank 11 is connected to one end of the corrugated expansion pipe 13 through the water pump. The other end of the corrugated expansion pipe 13 is connected to the rotary joint 12. The use of the corrugated expansion pipe 13 to connect the water tank 11 and the rotating water storage pan 501 ensures the continuity of water supply and avoids the pipe from getting tangled or broken during movement and rotation, thereby improving the reliability and service life of the equipment.

[0023] Working principle: In use, move the device to the construction dust area and activate the drive of the walking wheels 8 for positioning. The first lifting cylinder 203 of the lifting mechanism 2 pushes the platform 3 upward, adjusting the dust suppression mechanism 5 to a suitable height. The second motor 404 drives the lead screw 403 to rotate, causing the slider 402 and the dust suppression mechanism 5 to move horizontally along the slide groove 401, achieving lateral positioning of the dust-generating point. The first motor 507 is activated, and through the meshing transmission of the gear 506 and the gear ring 505, it drives the water storage pan 501 and its multiple nozzles 503 to rotate as a whole, expanding the water mist coverage area. The water pump in the water tank 11 pumps water into the water storage pan 501 through the corrugated expansion pipe 13 and the rotary joint 12. The water flows through the outlet pipe 502 to the nozzles 503, where it forms a micron-level water mist under the action of the atomizing plate 504, adsorbing and settling dust in the air. The entire dust suppression process can be automatically controlled, providing continuous and efficient dust suppression.
