[0024] refer to Figure 1 and Figure 5 Both ends of the protection roller 14 are rotatably connected with damping blocks 15 , and a plurality of damping grooves 16 are provided inside the extension frame 13 , and the plurality of damping grooves 16 are slidably connected with the plurality of damping blocks 15 , respectively.

[0025] As a technical optimization solution of the present invention, by setting the damping block 15 and the damping groove 16, the displacement trajectory of the protective roller 14 can be restricted, and a damping force can be provided for its movement, thereby absorbing the impact force.

[0026] refer to Figure 1 and Figure 5 A damping buffer 17 is fixedly connected to the inside of the damping groove 16 , and the damping buffer 17 is fixedly connected to the damping block 15 . A spring 18 is sleeved on the surface of the damping buffer 17 , and the spring 18 is used in conjunction with the damping buffer 17 .

[0027] As a technical optimization scheme of the utility model, by setting the damping buffer 17 and the spring 18, the elastic deformation of the spring 18 when subjected to an external force can be utilized to absorb the energy of the external force, and the elastic deformation of the spring 18 can be converted into mechanical energy through the damping buffer 17, thereby suppressing the repeated bouncing of the spring 18 after absorbing the impact, and attenuating the inherent vibration of the spring 18, thereby achieving buffering and shock absorption of the protective roller 14.

[0028] refer to Figure 2 and Figure 3 A plurality of refraction grooves 19 are formed on the surface of the noise reduction frame 3, and the plurality of refraction grooves 19 are evenly arranged.

[0029] As a technical optimization solution of the utility model, by setting a plurality of refraction grooves 19, when noise is transmitted into the refraction grooves 19, the refraction grooves 19 can be used to refract the sound waves, thereby extending the diffusion path of the sound waves and achieving a noise reduction effect.

[0030] refer to Figure 2 and Figure 3 The bottom of the water tank 7 extends to the interior of the storage chamber 2 and is connected to a retractable water inlet pipe 20.

[0031] As a technical optimization solution of the utility model, the provision of a retractable water inlet pipe 20 facilitates the provision of water to the interior of the water storage tank 7 .

[0032] refer to Figure 1 The cross-sectional area of ​​the combined pattern of several protective rollers 14 covers the surface of the noise reduction frame 3.

[0033] As a technical optimization solution of the utility model, by setting the cross-sectional area of ​​the combined pattern of several protective rollers 14 to cover the surface of the noise reduction frame 3, it can ensure that several protective rollers 14 can wrap the noise reduction frame 3, so that external objects will contact the protective rollers 14 first when colliding.

[0034] The working principle and use process of the utility model are as follows: when the staff uses the air dust prevention device in the construction project, the device is first installed to the designated position, and the retractable water inlet pipe 20 is connected to the external water supply system. When the dust needs to be reduced at the construction site, the lifting motor 6 can be started according to the construction needs, which can drive the threaded rod 5 to rotate, so that the threaded block 8 can be raised, and then the water tank 7 can be driven to rise, so that the diverter 11 and the atomizing nozzle 12 can be driven to rise to the designated height, and then the water pump 9 is started to provide water for the water pumping pipe 10, so that the diverter 11 and the atomizing nozzle 12 can be diverted and atomized to the water body, so as to achieve the effect of dust reduction. At the same time, the noise generated by the construction can be isolated by the noise reduction frame 3, and the sound waves can be refracted by the refraction groove 19, so as to be able to The diffusion path of the sound wave is extended, thereby improving the noise reduction effect. When foreign objects collide with the protective roller 14, since the protective roller 14 is in the shape of a rotatable drum, when the foreign objects come into contact with the protective roller 14, the rotatable characteristic of the protective roller 14 can be used to unload the force to a certain extent. At the same time, the two ends of the protective roller 14 drive the damping block 15 to squeeze the damping buffer 17 and the spring 18 in the damping groove 16. At this time, the spring 18 undergoes elastic deformation when subjected to external force, thereby absorbing the energy of the external force, and converts the elastic deformation of the spring 18 into mechanical energy through the friction between the damping groove 16 and the damping block 15, and the damping buffer 17, thereby suppressing the repeated bouncing of the spring 18 after absorbing the impact, and attenuating the inherent vibration of the spring 18, thereby achieving buffering and shock absorption of the protective roller 14, thereby protecting the device.
