[0021] The following is combined with Figure 1 - Figure 5 This application is described in further detail.

[0022] Reference Figure 1 - Figure 3 A dust suppression device for a construction site comprises a gun mist dust suppressor 1 and a frame 11 arranged on the gun mist dust suppressor 1, and a water tank 12 arranged in the frame 11. The gun mist dust suppressor 1 is provided with a water inlet pipe 13 connected to the water tank 12. The water tank 12 is provided in two. The water inlet pipe 13 can be connected to the two water tanks 12 at the same time. Two water tanks 12 are provided. Both water tanks 12 can be connected to the water inlet pipe 13 separately, and the water tanks 12 can be removed separately. Water can be taken from the other water tank 12 during the operation of one water tank 12. At this time, the gun mist dust suppressor 1 does not need to stop working to achieve continuous dust suppression. The interiors of the two water tanks 12 are switched. The form is interconnected with the inside of the water inlet pipe 13, a docking component 4 is arranged between the two water tanks 12 and the water inlet pipe 13, a bottom plate 2 is arranged at the bottom of the water tank 12, and a side plate 21 for limiting the water tank 12 is arranged on the side of the bottom plate 2, a vertical rod 22 is fixed to the bottom of the bottom plate 2, and a rotating moving wheel 23 is arranged at the lower end of the vertical rod 22, and a guide component 3 cooperating with the water tank 12 is provided on the frame 11, and the docking component 4 completes the docking through the guide component 3 and the vertical rod 22 and the moving wheel 23 at the lower end of the water tank 12, and a locking component 5 for stably connecting the water tank 12 to the frame 11 is arranged between the bottom plate 2 and the frame 11, and the docking component 4 is stably connected through the locking component 5.

[0023] Reference Figure 2 The guide component 3 includes a guide groove 31 provided on the frame 11. The guide groove 31 is set in a "V" shape, and the large-diameter end faces the outside of the frame 11. The frame 11 is also provided with a positioning groove 32 that communicates with the guide groove 31. The width of the positioning groove 32 is equal to the diameter of the vertical rod 22. The guide component 3 can accurately and conveniently introduce the water tank 12 into the frame 11, so that the docking component 4 and the locking component 5 can be accurately matched.

[0024] Reference Figure 3 - Figure 4The docking component 4 includes a three-way valve 41 connected to the water inlet pipe 13 through an interface and a docking pipe 42 connected to the other two interfaces of the three-way valve 41, and also includes a straight-through valve 43 connected to the water outlet of the water tank 12 and a docking sleeve 44 connected to the straight-through valve 43. The docking pipe 42 is plug-connected with the docking sleeve 44, and a sealing ring 45 is provided on the inner side of the docking sleeve 44 to seal the two. The docking component 4 is docked by moving the water tank 12 and using the guide component 3, which has the advantage of convenient operation and no deliberate docking and detachment of the docking component 4 is required.

[0025] Reference Figure 4 - Figure 5 The locking component 5 includes a positioning block 51 fixed to the lower end of the base plate 2 and a limiting groove 52 opened at the bottom of the frame 11, as well as a block 53 slidably arranged in the frame 11 and a foot pedal 54 fixed at the lower end of the block 53. The foot pedal 54 is also located at the lower end of the frame 11. A locking spring 55 is arranged between the block 53 and the foot pedal 54 and the frame 11. The contact surfaces of one end of the block 53 and the positioning block 51 are both chamfered, and the other ends are both flat. The block 53 locks the positioning block 51 in the limiting groove 52 under the action of the locking spring 55. The locking component 5 can be automatically engaged when the water tank 12 is installed, and can be disengaged by simply stepping down the foot pedal 54. It has the advantages of convenient operation and high reliability.

[0026] Working principle: Before using the cannon fog dust suppressor 1, step on the foot pedal 54 downward, the foot pedal 54 pulls the block 53 downward and disengages from the positioning block 51, the locking spring 55 is compressed accordingly, the water tank 12 is pulled outward, the moving wheel 23 rolls on the ground, the water tank 12 is removed alone, and then the other water tank 12 is also removed at the same time, and both water tanks 12 are filled with water;

[0027] When the water tank 12 is installed back, the vertical rod 22 enters the guide groove 31 to guide it into the positioning groove 32. At this time, the docking sleeve 44 and the docking tube 42 are in a concentric state, and the water tank 12 continues to be pushed. The vertical rod 22 moves along the positioning groove 32, and the docking sleeve 44 moves axially toward the docking tube 42. The docking sleeve 44 is sleeved on the outside of the docking tube 42, and the sealing ring 45 forms a seal between the two. During this movement of the water tank 12, the positioning block 51 also squeezes the block 53 downward, and the vertical rod 22 reaches the bottom of the positioning groove 32. The butt tube 42 and the docking sleeve 44 are completely connected. At this time, the positioning block 51 is locked by the block 53 under the action of the locking spring 55, and the water tank 12 is fixedly installed on the gun fog dust suppressor 1. The water tank 12 with water inlet is adjusted by the three-way valve 41, and the gun fog dust suppressor 1 is directly started to work;

[0028] When the water in one water tank 12 is used up, the three-way valve 41 is turned to switch the water tank 12 that is inlet. At this time, the used water tank 12 can be taken out separately to be filled with water, and the cannon fog dust suppressor 1 and the other water tank 12 continue to work together.

[0029] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
