[0035] During specific implementation, a rotating seat 18 is provided at the bottom of the support rod 21, and two rotating shafts 8 are symmetrically arranged on the rotating seat 18. The rotating seat 18 can be rotatably inserted into the interior of the mounting seat 7, and is rotatably connected to the two side walls of the mounting seat 7 through the two rotating shafts 8, so that the rotating seat 18 can rotate in the mounting seat 7, thereby driving the support rod 21 to rotate in the mounting seat 7.

[0036] See also Figure 1 and Figure 3 The construction dust suppression device further comprises: two docking plates 9 and two locking members 10. The top surfaces of the two side walls of the mounting seat 7 are provided with first arcuate grooves, and each first arcuate groove is recessed from the top surface to the bottom surface of the side wall.

There are also two second threaded holes on the top surface of each side wall of the mounting seat 7, and the two second threaded holes are respectively placed on both sides of the first arc-shaped groove. Correspondingly, there are four locking members 10.

[0041] It can be seen that in this embodiment, the support rod 21 is rotatably connected to the two side walls of the mounting seat 7 through the two rotating shafts 8, and the structure is simple and easy to implement.

[0042] See also Figure 1 , Figure 3 and Figure 4In each of the above embodiments, the locking mechanism includes: two locking assemblies 3. The two locking assemblies 3 are respectively arranged on both sides of the support rod 21, each locking assembly 3 is horizontally arranged between the two side walls of the mounting seat 7, and each locking assembly 3 blocks the space between the opposite side walls of the mounting seat 7. Specifically, the support rod 21 rotates between the two side walls of the mounting seat 7, and when the support rod 21 rotates to a vertical state, the two locking assemblies 3 block and lock the support rod 21. In this way, the two locking assemblies 3 and the two side walls of the mounting seat 7 block and position the bottom of the support rod 21, so that the support rod 21 remains in a vertical state. After the two locking assemblies 3 cancel the locking and blocking of the support rod 21, the support rod 21 can be rotated to a horizontal state, which is convenient for repairing the support rod 21 and the sprayer 5 and other components without disassembling the entire device, which is convenient for daily maintenance of the device.

[0043] Each locking assembly 3 includes a locking plate 31 and a locking bolt 32. The locking plate 31 is placed on one side of the mounting seat 7 and is perpendicular to the two side walls of the mounting seat 7. A protrusion 33 is provided on the inner side of the locking plate 31. The protrusion 33 is sandwiched between the two side walls of the mounting seat 7, and the protrusion 33 is in contact with the support rod 21. Specifically, the cross-sectional size of the protrusion 33 matches the distance between the two side walls of the mounting seat 7, and the locking plate 31 and the protrusion 33 form a T-shaped structure.

[0044] The locking plate 31 is provided with a third threaded hole, which penetrates the locking plate 31 and the protrusion 33. Specifically, the third threaded hole is provided at the locking plate 31 corresponding to the protrusion 33, and the third threaded hole penetrates the locking plate 31 and the protrusion 33 from the outside of the locking plate 31. The locking bolt 32 is screwed into the third threaded hole, and the end of the locking bolt 32 abuts against the support rod 21. In this way, when the support rod 21 rotates to a vertical state, the two protrusions 33 block and position the support rod 21 from both sides of the support rod 21, and the two protrusions 33 accurately position the support rod 21 with the two side walls of the mounting seat 7. After being screwed into the corresponding third threaded holes, the two locking bolts 32 abut against the support rod 21, and the two locking bolts 32 lock the support rod 21, preventing the support rod 21 from rotating between the two side walls of the mounting seat 7, so that the support rod 21 remains in a vertical state in the mounting seat 7.

[0045] In a specific implementation, the two protrusions 33 clamp the rotating seat 18 at the bottom of the support rod 21, and then the rotating seat 18 is locked by two locking bolts 32, so that the rotating seat 18 and the support rod 21 are kept in a vertical state together.

[0046] In specific implementation, fourth threaded holes can be provided on the two opposite side walls of the rotating seat 18 and corresponding to the two locking bolts 32. The two locking bolts 32 correspond to the two fourth threaded holes one by one. The two locking bolts 32 are screwed into the corresponding third threaded holes and then screwed into the corresponding fourth threaded holes. In this way, the two locking bolts 32 are screwed into the two fourth threaded holes, thereby fixing the two locking bolts 32 and the rotating seat 18 relatively, so that the rotating seat 18 remains in a vertical state.

The second end of the water pipe 12 is detachably connected to the connecting ring 19, which is disposed on the support plate 4, and the connecting ring 19 is connected and communicated with each sprayer 5. The first end of the water pipe 12 is used to be connected to an external water source, and the external water source transports water into the water pipe 12, and then transports it into the connecting ring 19, and then transports it to each sprayer 5.

[0048] Each positioning sleeve 13 is arranged at intervals on one side of the sleeve 22 along the height direction of the sleeve 22. Preferably, each positioning sleeve 13 is evenly distributed along the height direction of the sleeve 22. The water pipe 12 is sequentially passed through each positioning sleeve 13, and each positioning sleeve 13 positions the water pipe 12. Specifically, each positioning sleeve 13 includes: a positioning rod and a positioning ring, the first end of the positioning rod is vertically connected to the side wall of the sleeve 22, the second end of the positioning rod is connected to the positioning ring, the inner diameter of the positioning ring is larger than the outer diameter of the water pipe 12, and the water pipe 12 is passed through the positioning ring.

[0049] In specific implementation, since the height of the support device 2 is adjustable, the length of the water pipe 12 has a preset margin, so that when the height of the support device 2 is adjusted, it does not affect the use of the water pipe 12. Of course, when adjusting the height of the support device 2, the support device 2 can also be rotated to a horizontal state, and after the height of the support device 2 is adjusted, the water pipe 12 is replaced so that the length of the water pipe 12 matches the height of the adjusted support device 2.

[0050] It can be seen that in this embodiment, water is supplied to each sprayer 5 through the water pipe 12 to ensure normal spraying and dust reduction of the sprayer 5, and each positioning sleeve 13 can position the water pipe 12 to ensure that the water pipe 12 is parallel to the height direction of the support device 2, thereby ensuring the stable operation of the water pipe 12.
