[0027] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0030] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0031] Reference Figures 1-7 This is one embodiment of the present invention, which provides a water spraying device for construction sites, including a fog cannon 1, a rotating movable support 11 installed at the bottom of the fog cannon 1, a rotating chassis 12 installed at the bottom of the rotating movable support 11, an angle adjustment component 13 installed at the top of the rotating chassis 12, a nozzle 15 provided at the end of the fog cannon 1, and a fixed pipe 14 connected to the nozzle 15. When the fixed pipe 14 and the nozzle 15 are tilted up and down with the angle adjustment component 13, the piston rod 322 is reciprocated by the fog cannon 1. A conversion block 2 is installed at the end of the fixed pipe 14. A gas connection pipe 21 is installed on one side of the outer wall of the conversion block 2. The top of the conversion block 2 is connected to one end of the fixed pipe 14. A fixed sleeve 26 is provided inside the conversion block 2. A rotating shaft 22 is installed inside the fixed sleeve 26. A flow groove 23 is opened inside the rotating shaft 22. The top of the flow groove 23 is connected to the fixed pipe 14. A drive assembly 24 for rotating the rotating shaft 22 is installed at the bottom of the conversion block 2. A water inlet pipe 25 is installed on one side of the outer wall of the conversion block 2. The water inlet pipe 25 is kept connected to the fixed pipe 14 when the fog cannon 1 is working and is cut off by the rotating shaft 22 before the nozzle 15 is lowered to the lowest point. When the nozzle 15 of the fog cannon 1 is lowered to the lowest point, the sliding pressing strip 244 on one side of the conversion block 2 contacts the outer wall of the angle adjustment assembly 13. 44 moves along the support bar 243 under pressure, and the sliding pressing bar 244 moves, causing the embedded convex ball 246 to move. The embedded convex ball 246 moves along the spiral arc groove 242, causing the rotating block 241 to rotate. The rotation of the rotating block 241 causes the rotating shaft 22 to rotate, which closes the spray channel originally formed by the fixed pipe 14, the water inlet pipe 25 and the flow channel 23, and converts it into a flow channel of the fixed pipe 14, the flow channel 23 and the gas connection pipe 21. At this time, the gas in the gas tank 3 is quickly sprayed out along the flow channel of the fixed pipe 14, the flow channel 23 and the gas connection pipe 21. Finally, the airflow is sprayed out from the nozzle 15. At this time, the gas quickly squeezes out the water at the nozzle 15 at the fixed pipe 14 and the nozzle 15, effectively draining the water around the fixed pipe 14 and the nozzle 15, effectively preventing the nozzle 15 from being damaged due to freezing in winter.

[0032] Specifically, the fixed sleeve 26 is provided with a through hole, and the two ends of the through hole are connected to the gas connection pipe 21 and the water inlet pipe 25 of the conversion block 2, respectively. After the rotating shaft 22 rotates 180°, the through hole makes the gas connection pipe 21 and the fixed pipe 14 instantly connected.

[0033] Furthermore, the drive assembly 24 includes a rotating block 241 installed at the bottom of the rotating shaft 22. The outer wall of the rotating block 241 is provided with a spiral arc groove 242. A support bar 243 is installed at the bottom of the conversion block 2. A sliding pressing bar 244 is movably connected to the support bar 243. A support spring 245 is installed at the top of the sliding pressing bar 244, and the top of the support spring 245 is fixedly connected to the bottom of the conversion block 2. An embedded protruding ball 246 is installed on the outer wall of the sliding pressing bar 244, and the embedded protruding ball 246 is embedded in the spiral arc groove 242. When the sliding pressing bar 244 is pressed to the top by the angle adjustment assembly 13, the support spring 245 is compressed to the limit and the position of the rotating shaft 22 is locked.

[0034] Furthermore, the sliding press bar 244 is located on the top side of the angle adjustment component 13. When the angle adjustment component 13 lowers the height of one side of the nozzle 15, the sliding press bar 244 can press against one side of the outer wall of the angle adjustment component 13. When the support spring 245 is in its original state, the flow groove 23 is located on the side of the water inlet pipe 25. At this time, the water inlet pipe 25 is connected to the fixed pipe 14. When the sliding press bar 244 moves to the top side, the flow groove 23 rotates towards the side of the gas connection pipe 21. The moment the nozzle 15 drops to the lowest point, the sliding press bar 244 completes the switching and triggers the gas tank 3 to exhaust.

[0035] Furthermore, an air storage tank 3 is installed on the top of the rotating chassis 12, and a pressure injection pipe 31 is installed on the outer wall of the air storage tank 3. A pressure injection column 32 is installed at one end of the pressure injection pipe 31. The pressure injection column 32 pressurizes the gas into the air storage tank 3 as the fog cannon 1 pitches and cycles until the injection pressure is reached.

[0036] Furthermore, a piston plate 321 is installed on the inner wall of the injection column 32, and a piston rod 322 is installed on the top of the piston plate 321. One end of the piston rod 322 extends out of the top of the injection column 32, and a movable connecting rod 323 is installed on the top of the piston rod 322. One end of the movable connecting rod 323 is movably connected to the bottom side of the fog cannon 1 through a pin. The vertical stroke of the piston rod 322 is synchronized with the pitch angle of the fog cannon 1 to achieve continuous injection.

[0037] Furthermore, an air inlet valve 4 is installed on the inner wall of the injection column 32, and one end of the air inlet valve 4 extends out of the outside of the injection column 32, while an air outlet valve 41 is installed on the inner wall of the other side of the injection column 32.

[0038] Furthermore, a fixing bracket 42 is installed on the inner wall of the air outlet valve 41, a fixing spring 43 is installed on one side of the outer wall of the fixing bracket 42, a sealing plate 45 is installed on one end of the fixing spring 43, and a mating ring 44 is installed on the inner wall of the air outlet valve 41.

[0039] Furthermore, the fixed spring 43 applies tension to the sealing plate 45, causing one side of the sealing plate 45 to fit against the mating ring 44, thereby realizing the one-way air outlet function of the air intake valve 4.

[0040] Furthermore, the exhaust valve 41 and the intake valve 4 have the same structure, so that when the piston plate 321 moves upward, air begins to enter through the intake valve 4, and when the piston plate 321 moves downward, the intake valve 4 naturally closes to prevent air leakage. The two valves alternately open and close to ensure that the gas in the storage tank 3 only enters and does not exit until the nozzle 15 finishes purging. During the movement of the fog cannon 1, its piston rod 322 is pulled up and down repeatedly by the fog cannon 1. When the piston rod 322 moves downward, it drives the piston plate 321 to move. The downward movement of the piston plate 321 causes the gas in the injection column 32 to be squeezed into the injection pipe 31 through the intake valve 4 and stored in the storage tank 3 through the injection pipe 31. When the piston plate 321 moves upward, the intake valve 4 opens and the exhaust valve 41 closes. At this time, the external gas automatically replenishes the inside of the injection column 32, so that the inside of the storage tank 3 achieves cyclic injection, eliminating the need for gas tanks for gas supply, and making this gas supply structure maintenance-free.

[0041] Operation process: When the fog cannon 1 is in use, the rotating chassis 12 drives the fog cannon 1 to rotate, and the angle adjustment component 13 drives the fog cannon 1 to adjust the angle, thereby completing multi-angle spraying and effectively watering and dust suppression on the construction site. During the use of the fog cannon 1, when the fog cannon 1 is moved, its piston rod 322 is pulled up and down by the fog cannon 1. When the piston rod 322 moves downward, the piston rod 322 moves and drives the piston plate 321 to move. The downward movement of the piston plate 321 makes the injection... Gas inside the pressure column 32 is forced into the injection pipe 31 through the air inlet valve 4 and stored in the air tank 3 through the injection pipe 31. When the piston plate 321 moves upward, the air inlet valve 4 opens and the air outlet valve 41 closes. At this time, external gas is automatically replenished inside the pressure column 32, so that the injection action can be continuously performed as the angle of the fog cannon 1 is adjusted. After the fog cannon 1 is used up, the angle adjustment component 13 drives the nozzle 15 of the fog cannon 1 to move downward, so that the nozzle 15 and the liquid droplets attached to the fog cannon 1 are... As the water drips naturally and reaches its lowest point at the nozzle 15 of the fog cannon 1, the sliding pressing strip 244 on one side of the conversion block 2 contacts the outer wall of the angle adjustment component 13. Under pressure, the sliding pressing strip 244 moves along the support strip 243. This movement causes the embedded convex ball 246 to move, which in turn moves along the spiral groove 242, causing the rotating block 241 to rotate. The rotation of the rotating block 241 then rotates the rotating shaft 22, causing the original fixed pipe 14, water inlet pipe 25, and flow... The spray channel formed by the through groove 23 is closed and converted into a flow channel of fixed pipe 14, flow groove 23 and gas connection pipe 21. At this time, the gas in the gas storage tank 3 is quickly sprayed out along the flow channel of fixed pipe 14, flow groove 23 and gas connection pipe 21. Finally, the airflow is sprayed out from the nozzle 15. At this time, the gas quickly squeezes out the water at the nozzle 15 at the fixed pipe 14 and the nozzle 15, effectively draining the water around the fixed pipe 14 and the nozzle 15, effectively preventing the nozzle 15 from being damaged due to freezing in winter.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
