[Specific implementation method]

[0025] like Figures 1 to 4 As shown, in this embodiment, the foldable spray dust suppression device mainly includes two bracket components, a fixing component, and a spray device.

[0026] Each bracket assembly includes an upper bracket 16, a front bracket 3 and a rear bracket 2. The upper bracket 16 is provided with a U-shaped fixing groove 161 for fixing the main water inlet pipe 1. When the upper bracket 16 rotates, it can drive the main water inlet pipe 1 to rotate together. The rear bracket 2 is provided with a U-shaped groove 21, which is semi-engaged with the U-shaped fixing groove 161 of the upper bracket. The front bracket, the rear bracket, the two side edges of the upper bracket and the rear side edge of the rear bracket are all provided with a fixing boss 6. The front side edge of the front bracket is also provided with a sliding groove 11 and a receiving groove 112, and the sliding groove 11 is provided with a plurality of grooves 111 along the up and down directions.

[0027] The fixing assembly includes two side fixing rods 7, a rear end fixing rod 5, an X-shaped folding plate 12, and a movable folding plate 4. The two side fixing rods 7 are used to cooperate with the fixing bosses on the two side edges of the front bracket and the rear bracket to lock the relative position between the front bracket and the rear bracket. The rear end fixing rod 5 is used to cooperate with the fixing bosses on the rear side edges of the rear end brackets of the two bracket assemblies to lock the relative position between the two bracket assemblies. The X-shaped folding plate 12 includes two X-shaped fixing plates that cross, and the two fixing plates are connected to rotate by the movable joint in the middle. One end of the two fixing plates is respectively pivoted to the front end brackets of the two bracket assemblies, and the other end has a T-shaped truncated cone structure 121, which can cooperate with the groove 111 in the sliding card slot 11 to realize the folding and unfolding between the two bracket assemblies. The movable folding plate 4 is pivoted in the receiving groove 112 of the front bracket and can be flipped upward to cooperate with the fixing boss of the upper bracket after flipping up to fix the upper bracket at a set angle.

[0028] When the upper bracket is rotated to a proper spray angle, the movable folding plate 4 is rotated upward and connected to the fixed boss 6 on the upper bracket 16 to ensure stable fixation. The upper bracket 16 can be set to have a 15-degree rotation angle above the horizontal plane and a 90-degree rotation angle below the horizontal plane. The front bracket 3 is fixed and rotatably connected at the position below the U-shaped groove 21, and the front bracket 3 and the rear bracket 2 form a certain angle, and the angle size is constrained not to be greater than 60 degrees.

[0029] The spray device is mainly composed of a main water inlet pipe 1, a spray pipe 14, and a spray nozzle 13. The spray device is composed of three spray pipes 14, and each spray pipe 14 has six spray nozzles 13. The spray nozzles 13 can be replaced according to different scenes and needs, and different spray nozzles 14 spray droplets of different sizes.

[0030] The universal wheel 9 is installed at the bottom of the bracket assembly through a rotating connection, and can realize 360-degree full-scale rotation in the horizontal plane. It is also equipped with a brake device, which can fix the position of the universal wheel during the spray dust reduction process, thereby effectively preventing the equipment from deviating from the spray direction due to displacement.

[0031] The method of using the foldable spray dust suppression device is described as follows.

[0032] When using the device, the device should be placed in an area where dust reduction is required, and a stability test should be performed before use. Confirm whether the universal wheel 9 and the brake device 8 can operate normally. Brake the universal wheel 9. Expand the front bracket 3 and the rear bracket 2 around the area as the center. During the expansion process, the lower end of the X-shaped folding plate 12 will slide upward along the sliding card slot 11, and according to the size of the left and right spacing, the T-shaped cone structure 121 at the lower end of the X-shaped folding plate 12 will be fixed to the groove 111 of the sliding card slot 11. After the fixation is completed, the rear end fixing rod 5 needs to be installed on the fixing boss 6 of the rear end bracket 2 to prevent the bracket from shifting left and right during use. The front bracket 3 and the rear end bracket 2 will rotate driven by the coaxial center. When the two are expanded to a predetermined angle, the fixing rods 7 on both sides need to be installed. The fixing rods 7 on both sides should be precisely matched with the concentric circles of the fixing boss 6, and the inner sides of the fixing rods 7 on both sides should be close to the innermost end of the fixing boss 6 to ensure that the bracket assembly is stable front and back and does not shift. Fix the main water inlet pipe 1 in the U-shaped fixing slot of the upper bracket 16, and adjust the spray direction of the upper bracket 16. At this time, the movable folding plate 4 needs to be flipped upward and matched with the fixed boss at the corresponding position of the upper bracket. Connect the main water inlet pipe 1 to the water pipe system through the joint, start the water supply and adjust the switch of the water stop valve 14, and observe whether the water pressure on the pressure gauge 15 is within the normal range. After completing the above operations, the device can be put into use according to actual needs.

[0033] After use, the following steps can be followed: disassemble the spray device and open the valve of the water stop valve 17 to release the residual water in the spray pipe 14 and the main water inlet pipe 1 to ensure that the spray device remains dry; release the brake stop device 8 of the universal wheel 9 so that the universal wheel 9 can rotate freely; remove the rear end fixing rod 5 of the rear end bracket 2, and pull the front end bracket 3 and the rear end bracket 2 to the left and right sides so that the lower end of the X-shaped folding plate 12 is out of the groove; drag the lower end of the X-shaped folding plate 12 to the bottom of the sliding card slot to complete the left and right folding of the front end bracket 3 and the rear end bracket 2; remove the fixing rods 7 on both sides, rotate the front end bracket 3 and the rear end bracket 2 to fit together, and place the rear end bracket 2 flat on the ground; gently lift the upper end bracket 16, and move the movable folding plate 4 obliquely backward to disengage the groove of the movable folding plate 4 from the fixed boss 6; after disengagement, rotate the movable folding plate 4 downward to reset it to the receiving groove 112 of the front end bracket; flip the upper end bracket 16 downward to make it fit closely with the front end bracket 3 to complete the folding operation of the bracket.

[0034] It should be noted that the above specific implementation methods are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to examples, those skilled in the art should understand that the technical solutions of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
