DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Example

[0030] Reference Figure 1-6 As shown, a dust prevention device for construction engineering includes a dust prevention plate 1, which is used efficiently by spraying water to remove dust, ensuring that the dust on the construction site will not be too large and affect the health of construction workers. The dust reduction principle is as follows: Wetting and condensation: by atomizing water into tiny water droplets, these water droplets quickly diffuse in the air and collide with dust particles in the air, thereby wetting and condensing the dust particles. Increased mass and diameter: water vapor gathers around the dust particles, increasing the mass and diameter of the dust particles, which helps the collision between the dust particles, thereby reducing the rebound force and promoting the sedimentation of the dust particles. Intercepting and capturing dust: Dust particles with larger mass and diameter are affected by gravity and inertia. When the distance between the water mist particles and the center of mass of the dust particles is less than their radius, the two will stick together, thereby intercepting the dust particles. Influence of inertia coefficient: For dust particles with a diameter greater than 0.5-1 μm, the relative speed between them and the water droplets and the diameter of the water droplets will affect the inertia coefficient of the dust, making it easier to remove dust. Diffusion capture: Dust particles with a diameter of less than 0.2μm mainly perform Brownian motion and can be diffused and captured by water mist particles. Micron-sized water mist particles: The water spray dust reduction system produces micron-sized water mist particles of the same size as dust particles, which increases the air humidity and absorbs a large amount of air latent heat, playing a cooling role. Gravity sedimentation: The sprayed water droplets adhere to the solid dust in the air, increasing its gravity and causing it to fall freely. Interception and dust replenishment: When solid particles such as dust collide with water droplets, the dust particles will be wetted and intercepted. Material wetting: After the material is wetted, the fine dust adheres to the large particles with water as a binder, preventing the generation of dust. High-pressure pump: Use a high-pressure pump to pressurize the water to 50-70 kg, and send it to the high-pressure nozzle through a high-pressure pipeline for atomization, forming a floating water mist. These micron-sized water mist particles can quickly absorb various dust particles of different sizes in the air.

The water supply mechanism includes a water tank 211, a water pump 212 and a water inlet 215. A water pump 212 is installed at the top of the water tank 211, and the input end of the water pump 212 is connected to the inside of the water tank 211, and the output end is connected to the delivery pipe 214. A water inlet 215 is provided at the top of the water tank 211, and the water inside the water tank 211 can be passed into the delivery pipe 214 by turning on the water pump 212. A plurality of groups of water spray ports 216 are provided at the top of the delivery pipe 214, and water can be sprayed outward through the plurality of water spray ports 216. The outer wall of the delivery pipe 214 is sleeved with a movable sleeve 313 corresponding to the water spray port 216, and a sealing layer 314 is fixed to the inner wall of the bottom end of the movable sleeve 313. The sealing layer 314 is made of rubber material, and the rubber material has a good sealing effect, ensuring that dust does not directly enter the water spray port 216 when the equipment is not in use, and has a good protective effect. The outer wall of the movable sleeve 313 is fixed with a connecting block 312, and the rear end of the dustproof plate 1 is slidably connected with a movable plate 311 fixed with several groups of connecting blocks 312. By sliding the movable plate 311, multiple connecting blocks 312, movable sleeves 313 and sealing layers 314 can be driven to move at the same time. This moving method is simpler and more efficient.

[0032] The side wall of the dustproof plate 1 is fixed with a limiting sleeve 213, which is sleeved on the outer wall of the delivery pipe 214. The setting of the limiting sleeve 213 can play a good supporting effect, and is convenient for supporting and positioning the delivery pipe 214. A filter sleeve 217 is sleeved inside the water inlet 215, and a pad 218 supported by the top of the water inlet 215 is fixed on the top of the filter sleeve 217. A plurality of groups of filter holes 219 are opened inside the filter sleeve 217, and the filter holes 219 can filter impurities in the water. The staff can pull the pad 218 upwards to remove the filter sleeve 217 and clean the impurities inside it.

[0033] The outer wall of the moving plate 311 is fixed with a rack plate 315, the rear end of the dustproof plate 1 is fixed with a mounting plate 316, the top of the mounting plate 316 is installed with a motor 317, the output end of the motor 317 is connected with a rotating rod 318, the end of the rotating rod 318 away from the motor 317 is fixed with a rotating gear 319 meshing with the rack plate 315, after the motor 317 is turned on, the rotating rod 318 and the rotating gear 319 are driven to rotate, the rotating gear 319 can mesh with the rack plate 315, and push the rack plate 315 to move back and forth horizontally, and achieve automatic driving of multiple movable sleeves 313 to move synchronously, the operation is more automated, and it is more time-saving and labor-saving to use. A sliding block 320 is fixed to the side of the moving plate 311 away from the rack plate 315, and the rear end of the dustproof plate 1 is provided with a sliding groove 321 that is distributed horizontally and slides with the sliding block 320. The sliding groove 321 and the sliding block 320 are set to ensure that the lateral movement of the rack plate 315 is sufficiently stable.

[0034] Working principle: when the water outlet 216 needs to be protected, the motor 317 is turned on to drive the rotating rod 318 and the rotating gear 319 to rotate, and the rotating gear 319 drives the rack plate 315 to move horizontally, and drives the movable plate 311, the connecting block 312, the movable sleeve 313 and the sealing layer 314 to move to the left. At this time, each movable sleeve 313 and the sealing layer 314 can cover each water outlet 216, and the sealing layer 314 can fit tightly to the outer wall of the conveying pipe 214. At this time, dust will not enter the inside of the water outlet 216, thereby playing a better protective role.

[0035] When it is needed, water is added into the water tank 211 through the water inlet 215, and the water enters through the filter sleeve 217 and the filter hole 219. The filter hole 219 has a good filtering effect. Then the water pump 212 is turned on to drive the water inside the water tank 211 to flow into the delivery pipe 214. At this time, the water can be sprayed outward through multiple water spray ports 216 to achieve a better dust prevention effect.
