[0025] 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.

[0026] Reference Figures 1-5 As shown, this utility model provides a dust suppression device for construction, including a housing 1, a mist cannon shell 2 on the top of the housing 1, a slot 21 in the middle of the mist cannon shell 2, a fan 3 inserted into the inner wall of the slot 21, filter plates 22 fixedly connected to the inner walls of both ends of the mist cannon shell 2, a drive shaft 23 rotatably connected to the center of the filter plate 22, a cross plate 24 fixedly sleeved at one end of the drive shaft 23, the cross plate 24 fitting into the inner slot of the fan 3, the other end of the drive shaft 23 passing through the interior of the filter plate 22 and fixedly connected to a scraper 25, the inner side of the scraper 25 contacting the outer side of the filter plate 22, a fixing ring 27 fixedly sleeved at the end of the drive shaft 23 near the filter plate 22, a first spring 28 movably connected to one side of the fixing ring 27, one end of the first spring 28 fixedly connected to one side of a sliding ring 29, the sliding ring 29 slidably connected to the outer surface of the drive shaft 23, one side of the sliding ring 29 contacting the inner side of the filter plate 22, and a pull ring 26 fixedly connected to the end of the filter plate 22 away from the cross plate 24.

[0027] In this embodiment, after the fan 3 is started, it generates a strong wind, which draws air in from one end of the fog cannon housing 2, filters it through the filter plate 22, and blows it out from the other end, forming a directional airflow to blow the dust-suppressing water mist to a distance to achieve the purpose of dust suppression. When the fan 3 rotates, its internal slot drives the cross plate 24 that is fitted with it to rotate. The cross plate 24 drives the drive shaft 23 to rotate together. When the drive shaft 23 rotates, it drives the scraper 25 to rotate. The scraper 25 can scrape off the dust and other impurities intercepted on the filter plate 22 to prevent the filter plate 22 from being blocked and to ensure smooth airflow.

[0028] When it is necessary to disassemble the fan 3 for maintenance, pull the pull ring 26. The pull ring 26 drives the drive shaft 23 to move outward, thereby causing the cross plate 24 to disengage from the internal slot of the fan 3.

[0029] As the drive shaft 23 moves outward, it drives the first spring 28 and the sliding ring 29 to move through the fixed ring 27. One side of the sliding ring 29 is in contact with the inner side of the filter plate 22. Therefore, the sliding ring 29 slides relative to the outer surface of the drive shaft 23 under the obstruction of the filter plate 22, and squeezes the first spring 28 to make it contract.

[0030] After the repaired fan 3 is installed, the pull ring 26 is released, and the first spring 28 rebounds. Because one side of the sliding ring 29 is in contact with the inner side of the filter plate 22, the first spring 28 drives the drive shaft 23 to move towards the fan 3 through the fixed ring 27. At this time, the cross plate 24 will re-embed into the internal slot of the fan 3, so that the fan 3 and the drive shaft 23 are reconnected. When the fan 3 rotates, it can drive the drive shaft 23 to rotate through the cross plate 24, thereby driving the scraper 25 to clean the filter plate 22 and maintain the normal operation of the dust suppression device.

[0031] This design, on the one hand, uses the rotation of fan 3 to drive cross plate 24, which in turn drives drive shaft 23 to rotate, causing scraper 25 to rotate and scrape off dust and impurities on filter plate 22, preventing filter plate 22 from clogging and ensuring smooth airflow. It eliminates the need for frequent manual cleaning of filter plate 22, saving labor costs and ensuring the continuous and stable operation of the dust suppression device. On the other hand, by pulling pull ring 26, drive shaft 23 can be moved, allowing cross plate 24 to disengage from the internal slot of fan 3, facilitating disassembly of fan 3 for maintenance. The operation is simple and convenient, shortening maintenance time and improving the maintenance efficiency of the dust suppression device.

[0032] In a further embodiment, a pull rod 4 is provided in the middle of the fog cannon housing 2, and a limiting rod 41 is symmetrically provided on one side of the pull rod 4. One end of the limiting rod 41 passes through the middle of the fog cannon housing 2 and extends to the upper slot of the fan 3. A second spring 42 is sleeved on the outer surface of the limiting rod 41, and the two ends of the second spring 42 are respectively connected to one side of the pull rod 4 and one side of the middle of the fog cannon housing 2.

[0033] In this embodiment, when installing the fan 3, simply pull the lever 4 outward to make one end of the limiting rod 41 leave the slot 21 and stretch the second spring 42. Then insert the fan 3 into the slot 21. Finally, release the lever 4. The elastic force of the second spring 42 will drive the lever 4 to automatically engage with the upper slot of the fan 3 through the lever 4, thus completing the installation.

[0034] This design allows the fan 3 to be easily inserted into or removed from the fog cannon housing 2 without complicated operations and tools, greatly improving the efficiency of fan 3 installation and removal, and facilitating routine maintenance, repair or replacement of the fan 3.

[0035] In a further embodiment, the box 1 is provided with an angle adjustment mechanism 5 and a water supply mechanism 7. An equipment room 11 is opened at the top inside the box 1, and a water storage room 12 is opened at the bottom inside the box 1. A maintenance door 13 is movably connected to one side of the equipment room 11.

[0036] A motor 51 is fixedly installed on the rear side of the inner wall of the equipment room 11. A small gear 52 is fixedly sleeved on the output shaft of the motor 51. A gear ring 53 is meshed on the outer surface of the small gear 52. The gear ring 53 is fixedly sleeved on the bottom end of the turntable 54. The turntable 54 is rotatably connected to the top of the box 1. A support plate 55 is symmetrically connected to the top of the turntable 54. A fog cannon shell 2 is rotatably connected to the opposite side of the support plate 55.

[0037] An electric push rod 6 is movably connected to the bottom rear side of the fog cannon housing 2, and the bottom end of the electric push rod 6 is movably connected to the top of the support plate 55.

[0038] In this embodiment, when the angle needs to be adjusted, the motor 51 is started, and its output shaft drives the pinion 52 to rotate. The pinion 52 drives the turntable 54 to rotate through the gear ring 53, which can realize the 360° horizontal rotation of the fog cannon shell 2. When the electric push rod 6 extends and retracts, it can push the fog cannon shell 2 to adjust the angle in the vertical direction.

[0039] By controlling the operation of motor 51 and electric push rod 6, the spray angle of the fog cannon can be adjusted remotely or automatically without manual adjustment. This not only saves manpower but also ensures the safety of operators in complex or dangerous construction environments. The dust suppression device can accurately cover various areas according to different dust distributions at the construction site, greatly improving the dust suppression effect.

[0040] In a further embodiment, a water pump 71 is fixedly installed on the front side of the inner wall of the equipment room 11, and a water pump pipe 72 is fixedly connected to the input end of the water pump 71. The bottom end of the water pump pipe 72 passes through the bottom wall of the equipment room 11 and extends into the interior of the water storage chamber 12.

[0041] The output end of the water pump 71 is fixedly connected to a water delivery pipe 73, and the bottom end of the water delivery pipe 73 passes through the top wall of the equipment room 11 and is fixedly connected to a flexible hose 74.

[0042] One end of the hose 74 passes through the outer wall of the fog cannon housing 2 and is fixedly sleeved with an annular water distribution pipe 75. The annular water distribution pipe 75 is fixedly installed on the inner wall of the front side of the fog cannon housing 2, and several nozzles 76 are threadedly connected to the inner surface of the annular water distribution pipe 75.

[0043] In this embodiment, the water pump 71 is started, and the water pump 71 draws water from the water storage chamber 12 through the water pump pipe 72. After the water is pressurized by the water pump 71, it is transported through the water delivery pipe 73. The water enters the hose 74 from the water delivery pipe 73, and then is transmitted through the hose 74 to the annular water distribution pipe 75 inside the fog cannon housing 2. The annular water distribution pipe 75 distributes the water evenly to each nozzle 76, and finally the water is sprayed out by the nozzle 76 to form a water mist for dust suppression.

[0044] The design of the annular water distribution pipe 75 and multiple nozzles 76 allows water to be evenly distributed and sprayed, enabling the water mist to evenly cover the dust suppression area, effectively improving dust suppression efficiency and avoiding situations where local dust cannot be effectively suppressed. The flexible hose 74 is flexible and can adapt to changes in position when the angle of the fog cannon housing 2 is adjusted, ensuring that water supply is not affected. This ensures that the device can supply water and suppress dust normally under different spray angles, enhancing the adaptability and flexibility of the device.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
