DETAILED DESCRIPTION

[0022] As Figures 1-5 shown, an environmentally friendly watering device for municipal construction, comprising an engineering vehicle 1, the front end of the vehicle compartment of the engineering vehicle 1 is provided with a water tank 2, and the rear end is provided with a watering device. The water tank 2 is connected with the water pump 3 through a pipeline, and the water pump 3 is connected with the watering device through a water inlet pipe 6.

[0023] The watering device comprises a base 4, the upper end of the base 4 is symmetrically provided with a support 5, the upper end of the support 5 is provided with a U-shaped frame 9, one side of the outer side wall of the U-shaped frame 9 is provided with a rotating shaft 14, and the rotating shaft 14 penetrates through the support 5 and is connected with a hand wheel 15. The other side of the outer side wall of the U-shaped frame 9 away from the rotating shaft 14 is provided with a shaft hole, and a transmission shaft is rotatably installed in the shaft hole. The top of the support 5 is provided with a tightening screw 16, and the end of the tightening screw 16 penetrates into the support 5 and abuts against the rotating shaft 14. Specifically, the transmission shaft and the rotating shaft 14 together support the U-shaped frame 9, by rotating the hand wheel 15, the installation angle of the U-shaped frame 9 on the support 5 can be adjusted, after the adjustment is completed, the U-shaped frame 9 is fixed by the tightening screw 16 abutting against the rotating shaft 14, if adjustment is needed, the fixing of the tightening screw 16 is contacted.

[0024] One end of the rotating shaft is provided with a pinion 11, the other end penetrates out of the support 5 and is connected with a motor 12, and the motor 12 is fixed on the outer side wall of the support 5 through a motor mounting seat 13. The pinion 11 is engaged with an external gear 10, the external gear 10 is installed on the outer side wall of an air duct 7, and the air duct 7 is rotatably installed at the bottom center position of the U-shaped frame 9 through a support fixing structure. The top of the air duct 7 is provided with a fan blade 8, by starting the motor 12, the pinion 11 is rotated, and then the external gear 10 is rotated, the air duct 7 rotates around the support fixing structure at the center position as the axis, and then the fan blade 8 at the top rotates.

[0025] An annular pipe 17, connected to the water supply pipe 6, is rotatably installed at the end of the air duct 7 furthest from the fan blades 8. Several atomizing nozzles 19 are distributed circumferentially on the annular pipe 17. When water spraying is needed, the atomizing nozzles 19 are turned on. Due to the rotation of the fan blades 8, air containing atomized water droplets is drawn into the air duct 7. After acceleration and reversal, the air velocity at the liquid surface is increased, accelerating the diffusion of gas molecules. The air is then expelled from the fan blades 8, i.e., from the air duct 7, achieving the purposes of dust reduction, cooling, and air humidification, thus improving the construction environment.

[0026] The supporting and fixing structure includes a plurality of fixing rods 21 circumferentially distributed on the inner side wall of the air duct 7. The other end of each fixing rod 21 is fixedly connected to a support rod 20, and the other end of the support rod 20 is rotatably connected to the bottom center of the U-shaped frame 9. That is, the bottom of the U-shaped frame 9 serves to support the air duct 7, but does not hinder the rotation of the air duct 7, nor does it rotate with the air duct 7.

[0027] There is a gap between the external gear 10 installed around the outer periphery of the air duct 7 and the U-shaped frame 9 to avoid affecting the rotation of the air duct 7 and to provide a certain space for its rotation.

[0028] A plurality of pipe clamps 18 are circumferentially distributed on the inner wall of the air duct 7. The annular tube 17 slides in contact with the pipe clamps 18, meaning that the pipe clamps 18 rotate with the air duct 7 while the annular tube 17 remains stationary. Each pipe clamp 18 has an opening 1802, the width of which is greater than the outer diameter of the water supply pipe 6 and the outer diameter of the atomizing nozzle 19. This allows the pipe clamp 18 to pass smoothly through the water supply pipe 6 and the atomizing nozzle 19 without obstruction when rotating with the air duct 7. Furthermore, to improve the lubrication of the pipe clamps 18 and the annular tube 17 and reduce the coefficient of friction, the annular tube 17 can be made of metal with a smooth surface, and the opening 1802 is smaller than the outer diameter of the annular tube 17. A limiting groove 1801 is formed on the inner wall of the pipe clamp 18, and a limiting protrusion 1701 matching the limiting groove 1801 is installed on the annular tube 17, providing a certain limiting effect and making its relative rotation more stable and smooth.

[0029] The operation process of this utility model is as follows:

[0030] First, the water pump 3 is started, and the water in the water tank 2 enters the annular pipe 17 through the water inlet pipe 6 and is atomized and sprayed out from the atomizing nozzle 19. Then, the motor 12 is started, the pinion 11 rotates, and the external gear 10 meshing with it rotates, so that the air duct 7 rotates, and the fan blades 8 at the top of the air duct 7 rotate accordingly. Finally, the rotation of the fan blades 8 draws in the air with atomized water droplets in the air duct 7, and after acceleration and reversal, the air velocity on the liquid surface is increased, the diffusion of gas molecules is accelerated, and the air is discharged from the fan blades 8, thus achieving the purpose of dust reduction, cooling, and air humidification, and improving the construction environment.

[0031] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
