By setting the bolts 4, the device can be quickly and firmly fixed, so that it can work stably.

[0025] The input end of the power of the water pump 303 passes through the water tank 301 and extends to the interior of the water tank 301. The output end of the power of the water pump 303 passes through the water tank 301 and extends to the interior of the fixed frame 302. The front and back sides of the noise reduction barrier body 2 are fixedly connected to two reinforcement blocks 5. The bottom surface of each reinforcement block 5 is fixedly connected to the upper surface of the base 1. By setting the reinforcement block 5, the connection effect between the base 1 and the noise reduction barrier body 2 can be further increased, so that it can be connected and fixed more stably.

[0026] The output end of the power of the water pump 303 is fixedly connected to a two-way pipe 304, and the top of the two-way pipe 304 is fixedly connected to two sealed rotary joints 307. By setting the sealed rotary joint 307, the main function of the sealed rotary joint 307 is to input the liquid from one side of the pipe into the rotating or reciprocating equipment, and then discharge it from the equipment, while ensuring the sealing of the connection. The right side of the noise reduction barrier body 2 is fixedly connected to a connecting block 6, and three connecting holes 7 are provided on the front of the connecting block 6. By setting the connecting block 6 and the connecting holes 7, a platform for connecting and fixing the noise reduction barrier bodies 2 can be provided, thereby facilitating fixation during connection.

[0030] The working principle of the present utility model is: when in use, the staff first transports the device to a suitable location for use, and then turns on the power of the water pump 303 and the double-headed rotating motor 309 so that it can be in a powered state. Then the staff firmly fixes the device with four bolts 4, and then inserts the connecting block 6 of one noise reduction barrier body 2 into the interior of the connecting frame 8 of another noise reduction barrier body 2, and fixes it with the pin 9 and the nut 10. Then the staff injects an appropriate amount of water into the interior of the water tank 301 through the water injection pipe 11. Then, when the staff is performing construction work, the noise reduction barrier body 2 can play a part in the noise reduction work. At the same time, the staff turns on the water pump 303 and the double-headed rotating motor 309, and the water pump 303 is turned on. After it is turned on, the water inside the water tank 301 can be extracted and transmitted through the two-way pipe 304. The two-way pipe 304 transmits the extracted water to the inside of the rotating cylinder 305 through the sealed rotary joint 307. At the same time, with the cooperation of the atomizing nozzle 306, the extracted water is sprayed out, so as to process the dust in the surrounding air. At the same time, the double-headed rotating motor 309 can start to rotate after it is turned on. The rotation of the double-headed rotating motor 309 can drive the two worms 310 to rotate. When the worm 310 rotates, it can drive the worm gear 308 to rotate. At the same time, the rotating cylinder 305 can be driven by the worm gear 308 to rotate in cooperation with the sealed rotary joint 307, thereby further increasing the water spraying area and further improving the dust reduction effect.
