Technical Field

[0001] The present invention relates to the technical field of dust control, and in particular to a dust reduction device for vehicles passing through a construction site. Background Art

[0002] Construction projects are a general term for all types of buildings and engineering facilities that provide the material and technological foundation for human life and production. Construction projects are organized, purposeful, and large-scale economic activities. Based on their physical attributes, construction projects can be categorized into three types: architectural engineering, civil engineering, and mechanical and electrical engineering. They are projects that generate comprehensive production capacity or maximize project benefits during the reproduction of fixed assets. Construction projects refer to the construction of new or the renovation of existing fixed assets.

[0003] Construction site vehicles often carry large amounts of dirt and dust when entering and exiting. If they are driven directly onto the road, this dirt will fly up during travel, causing air pollution and increasing the level of inhalable particulate matter in the air, which is harmful to residents' health. Furthermore, if construction site vehicles carry dirt on the road, it will cause surrounding roads to become dirty and messy, seriously affecting the overall aesthetics of the city. Therefore, dust-prone construction site vehicles need to be treated to reduce dust. To prevent dust pollution and protect and improve the quality of the atmospheric environment, it is necessary to formulate dust pollution prevention and control implementation plans and implement effective measures to minimize and control the adverse environmental impacts of construction dust, striving to achieve harmony between construction and the environment.

[0004] Conventional technology typically uses water pools or flushing equipment at construction site entrances and exits to control dust generated by vehicles passing through the site. However, these methods are not very effective, as even dried tires still generate dust while driving within the construction site, causing air pollution. Summary of the Invention

[0027] like Figures 1 to 8 As shown, a dust suppression device for vehicles passing through a construction site includes:

[0028] The liquid storage container 2 is detachably connected to one side of the construction vehicle 1 and is used to store a flushing liquid. The flushing liquid is clean water or a dust suppressant dilution liquid. When the dust suppressant dilution liquid is used as the flushing liquid, the high molecular polymer molecules in the dust suppressant dilution liquid form a three-dimensional network structure, which captures dust particles through charge affinity and locks them in the network. After drying, the polymer solidifies into a continuous protective film on the dust surface, isolating the air from the dust, preventing secondary dusting, and achieving a better dust reduction effect.

[0029] A spray pipe 3 and a plurality of atomizing nozzles 4. The spray pipe 3 is detachably connected to the front end of the construction vehicle 1. The spray pipe 3 is provided with a plurality of spray holes. The spray pipe 3 is used to moisten the road ahead of the construction vehicle 1. The plurality of atomizing nozzles 4 are detachably connected near each tire of the construction vehicle 1. The liquid discharge direction of the atomizing nozzle 4 is toward the tire adjacent thereto. The atomizing nozzle 4 is used to moisten the corresponding tire.

[0030] The pump body has a liquid inlet end connected to the liquid storage container 2, and a liquid outlet end connected to the spray pipe 3 and the atomizing nozzle 4.

[0031] In order to facilitate the installation of the liquid storage container 2 and the multiple atomizing nozzles 4, the liquid storage container 2 and the multiple atomizing nozzles 4 can be connected to the construction vehicle 1 by magnetic attraction, that is, magnets are installed on the liquid storage container 2 and the multiple atomizing nozzles 4.

[0032] In order to facilitate the removal of the liquid storage container 2 and the multiple atomizing nozzles 4, the liquid storage container 2 and the multiple atomizing nozzles 4 can be adsorbed on the construction vehicle 1 through a switch magnet. When the switch magnet is turned on, magnetic force is generated, and when the switch magnet is turned off, the magnetic force disappears.

[0033] During specific use, before the construction vehicle 1 enters the construction site, the liquid storage container 2 is installed on the side of the construction vehicle 1, the spray pipe 3 is installed at the front end of the construction vehicle 1, and the atomizing nozzle 4 is installed near each tire. When the construction vehicle 1 is driving in the construction site, the pump body transports the flushing liquid in the liquid storage container 2 to the spray pipe 3 and multiple atomizing nozzles 4. The flushing liquid is sprayed out from the various spray holes of the spray pipe 3 to moisten the road, which is beneficial to reducing the dust raised by the construction vehicle 1 when it is moving. Multiple atomizing nozzles 4 perform atomization dust removal near each tire of the construction vehicle 1 to further reduce dust generation.

[0034] In order to achieve the purpose of synchronous movement of the construction vehicle 1 and dust reduction, preferably, the pump body includes a first mounting plate 5, a second mounting plate 6 and a negative pressure chamber 11 fixedly connected to the liquid storage container 2, the first mounting plate 5 is rotatably connected to a friction wheel 7 for friction contact with one of the tires of the construction vehicle 1, the friction wheel 7 is coaxially provided with a driving spur gear 8, the second mounting plate 6 is rotatably connected to a driven spur gear 9 meshing with the driving spur gear 8, the driven spur gear 9 is adjustably provided with an eccentric pin 10, the eccentric pin 10 is rotatably connected to a connecting rod 12, the connecting rod 12 is rotatably connected to a piston rod 13, the piston rod 13 is provided with a piston 14 slidingly connected to the negative pressure chamber 11, the negative pressure chamber 11 is provided with a liquid inlet pipe 15 connected to the liquid storage container 2 and a liquid outlet pipe 16 connected to the spray pipe 3 and each atomizing nozzle 4, and the liquid inlet pipe 15 and the liquid outlet pipe 16 are respectively provided with a one-way valve.

[0035] Specifically, when the construction vehicle 1 is traveling, the tire of the construction vehicle 1 drives the friction wheel 7 to rotate, the friction wheel 7 drives the driving spur gear 8 to rotate, the driving spur gear 8 drives the eccentric pin 10 to rotate via the driven spur gear 9, and the eccentric pin 10 drives the piston 14 to perform piston movement inside the negative pressure chamber 11 via the connecting rod 12 and the piston rod 13. Since the one-way valve on the liquid inlet pipe 15 only allows liquid to flow from the liquid storage container 2 to the negative pressure chamber 11, and the one-way valve on the liquid outlet pipe 16 only allows liquid to flow from the negative pressure chamber 11 to the liquid outlet pipe 16, the flushing liquid in the liquid storage container 2 is continuously transported to the spray pipe 3 and each atomizing nozzle 4. The flushing liquid is sprayed from each spray hole of the spray pipe 3 to moisten the road, which is beneficial to reducing dust raised by the construction vehicle 1 when traveling. The multiple atomizing nozzles 4 perform atomizing dust removal near each tire of the construction vehicle 1, further reducing dust generation. When the construction vehicle 1 stops, the pump body also stops working, saving flushing liquid and being energy-saving and environmentally friendly.

[0036] In order to save flushing fluid, preferably, a rectangular groove 17 is radially provided on the driven spur gear 9, a trapezoidal screw rod 18 is rotatably connected to the upper portion of the rectangular groove 17, a screw nut 19 is threadedly connected to the trapezoidal screw rod 18 and is slidably connected to the rectangular groove 17, and an eccentric pin 10 is provided on the screw nut 19.

[0037] Specifically, by rotating the trapezoidal screw 18 clockwise or counterclockwise, under the guidance of the rectangular groove 17, the trapezoidal screw 18 drives the screw nut 19 to move along the length direction of the rectangular groove 17. By adjusting the eccentricity of the eccentric pin 10, the stroke of the piston 14 is adjusted, and then the flow rate of the flushing liquid is adjusted, which has the effect of saving flushing liquid and extending the dust reduction time.

[0038] In order to achieve the purpose of improving the dust reduction effect, preferably, the driven spur gear 9 is coaxially provided with a driving bevel gear 26, the internal rotation of the liquid storage container 2 is connected to the stirring shaft 27, a plurality of stirring paddles 28 are provided on the stirring shaft 27, and a driven bevel gear 29 meshing with the driving bevel gear 26 is provided on the stirring shaft 27.

[0039] Specifically, when the flushing liquid is a dust suppressant dilution liquid, the driven spur gear 9 will drive the active bevel gear 26 to rotate during the rotation process, and the active bevel gear 26 will drive the stirring paddle 28 on the stirring shaft 27 to rotate through the driven bevel gear 29. The stirring paddle 28 stirs the dust suppressant dilution liquid in real time to prevent the dust suppressant dilution liquid from precipitating, improve the uniformity of the dust suppressant dilution liquid, and improve the dust reduction effect.

[0040] In order to achieve the purpose of improving the dust reduction effect, it is preferred that it also includes a mounting base 20 that is detachably connected to the construction vehicle 1, the spray pipe 3 is slidably connected to the mounting base 20, and the liquid outlet pipe 16 is provided with a water wheel shell 21 fixedly connected to the mounting base 20. The internal rotation of the water wheel shell 21 is connected to the impeller 22, and the water wheel shell 21 is coaxially provided with a turntable 23. The turntable 23 is eccentrically connected to the eccentric block 24, and the spray pipe 3 is provided with a drive groove 25 adapted to the eccentric block 24.

[0041] Specifically, to facilitate installation of mounting base 20, mounting base 20 can be magnetically connected to construction vehicle 1. Specifically, a magnet is attached to mounting base 20. To facilitate removal of mounting base 20, mounting base 20 can be attached to construction vehicle 1 using a switch magnet. When the switch is on, the magnet generates magnetic force, and when the switch is off, the magnetic force disappears. While construction vehicle 1 is in motion, flushing fluid enters water wheel housing 21 through outlet pipe 16. Impeller 22 rotates under the impact of the water flow, driving eccentric block 24 on turntable 23. Eccentric block 24 drives spray pipe 3 in a reciprocating motion via drive slot 25, expanding the dust reduction range and improving the dust reduction effect.

[0042] Preferably, the liquid storage container 2 is provided with a liquid inlet, and the liquid inlet is detachably connected to a sealing cover.

[0043] When the present invention is in use, the liquid storage container 2 is mounted on the side of the body of the construction vehicle 1 by magnetic attraction, the mounting base 20 is mounted on the front end of the construction vehicle 1, and the atomizing nozzle 4 is mounted near each tire. After the flushing liquid is added to the liquid storage container 2 through the liquid inlet, the liquid inlet is sealed with a sealing cover, and the trapezoidal screw 18 is rotated clockwise or counterclockwise to adjust the flow rate of the flushing liquid. When the construction vehicle 1 is driving in the construction site, the tire of the construction vehicle 1 drives the friction wheel 7 to rotate, and the friction wheel 7 drives the active spur gear 8 to rotate, and the active spur gear 8 drives the eccentric pin 10 to rotate through the driven spur gear 9. During the rotation process, the driven spur gear 9 will drive the active bevel gear 26 to rotate, and the active bevel gear 26 drives the stirring paddle 28 on the stirring shaft 27 to rotate through the driven bevel gear 29. The stirring paddle 28 stirs the dust suppressant dilution liquid in real time, and the eccentric pin 10 drives the piston 14 in the negative pressure chamber through the connecting rod 12 and the piston rod 13. The interior of the body 11 performs piston motion. Since the one-way valve on the liquid inlet pipe 15 only allows liquid to flow from the liquid storage container 2 to the negative pressure chamber 11, and the one-way valve on the liquid outlet pipe 16 only allows liquid to flow from the negative pressure chamber 11 to the liquid outlet pipe 16, the flushing liquid in the liquid storage container 2 is continuously transported to the spray pipe 3 and each atomizing nozzle 4. The flushing liquid enters the water wheel housing 21 through the liquid outlet pipe 16. The impeller 22 rotates under the impact of the water flow. The rotating impeller 22 drives the eccentric block 24 on the turntable 23 to rotate. The eccentric block 24 drives the spray pipe 3 to reciprocate left and right through the driving groove 25, thereby expanding the dust reduction range of the spray pipe 3. The flushing liquid is sprayed from each spray hole of the spray pipe 3 to moisten the road, which is beneficial to reducing dust raised by the construction vehicle 1 when it is moving. The multiple atomizing nozzles 4 perform atomization dust removal near each tire of the construction vehicle 1 to further reduce dust generation. When the construction vehicle 1 stops, the pump body also stops working.

[0044] Compared with the prior art, the present invention cooperates with a construction vehicle 1, a liquid storage container 2, a spray pipe 3, spray holes, multiple atomizing nozzles 4 and a pump body. Before the construction vehicle 1 enters the construction site, the liquid storage container 2 is installed on the side of the construction vehicle 1, the atomizing nozzles 4 are installed near each tire, and the spray pipe 3 is installed at the front end of the construction vehicle 1. When the construction vehicle 1 is driving in the construction site, the pump body transports the flushing liquid in the liquid storage container 2 to the spray pipe 3 and the multiple atomizing nozzles 4. The flushing liquid is sprayed from the various spray holes of the spray pipe 3 to moisten the road, which is beneficial to reducing dust raised by the construction vehicle 1 when it is moving. The multiple atomizing nozzles 4 perform atomization dust removal near each tire of the construction vehicle 1, further reducing dust generation, with strong timeliness and good dust prevention effect.
