DETAILED DESCRIPTION

[0025] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0026] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0027] like Figure 1-5 As shown, an embodiment of the utility model provides a fire-fighting spraying drone, which is composed of a main body mechanism 10 and a spraying mechanism 20.

[0028] The main body 10 includes a drone body 11, a fixing frame 12 and a mounting tube 15. The fixing frame 12 is fixedly connected to one side of the drone body 11. One side of the fixing frame 12 is respectively fixedly connected with a first fixing plate 13 and a second fixing plate 14. The mounting tube 15 is fixedly connected to one side of the first fixing plate 13 and is used to install a water supply structure. One side of the mounting tube 15 is fixedly connected to the second fixing plate 14. A water tank 19 is provided on one side of the interior of the mounting tube 15, and water is supplied through the water tank 19. A sealing cover 18 is threadedly connected to one side of the mounting tube 15. The sealing cover 18 limits the water tank 19 to prevent the water tank 19 from escaping from the mounting tube 15, so as to facilitate the replacement of the water tank 19.

[0029] In one embodiment, in order to reduce the impact of water sloshing in the water tank 19 on the stability of the drone body 11, partitions 31 are evenly distributed and fixedly connected to one side of the interior of the water tank 19, and a through hole 32 is integrally formed on one side of the partition 31. The partition 31 separates the water flow inside the water tank 19, thereby reducing the impact of the force generated by water sloshing on the overall stability.

[0030] In one embodiment, a buffer pad 17 is fixedly connected to one side of the interior of the installation tube 15 , and the buffer pad 17 is used to limit the water tank 19 and reduce the impact of the shaking of the water tank 19 on the installation tube 15 and the fixing frame 12 .

[0031] The spraying mechanism 20 includes a mounting plate 21, a nozzle 22 and a booster pump 23. The nozzles 22 are equidistantly mounted on one side of the mounting plate 21. A spray pipe 33 is mounted on one side of the mounting plate 21. The spray pipe 33 is connected to the nozzle 22. The booster pump 23 is mounted on one side of the first fixed plate 13. The water outlet of the booster pump 23 is connected to a connecting pipe 24. One end of the connecting pipe 24 is connected to the spray pipe 33. The water inlet of the booster pump 23 is connected to a water intake pipe 28. Water is pumped out of the water tank 19 through the water intake pipe 28. Both the water intake pipe 28 and the connecting pipe 24 are deformable hoses. A connecting sleeve 27 is mounted on one side of the water intake pipe 28. The connecting sleeve 27 is clamped with the water tank 19. A connecting sleeve 27 is provided to straighten the water intake pipe 28 for connection with the water tank 19. The water intake pipe 28 is communicated with the water tank 19. The two sides of the mounting plate 21 are fixedly connected with the rotating shaft 25. One end of the rotating shaft 25 is rotatably connected to the fixing frame 12. Two orifice plates 16 are fixedly connected to the two sides of the fixing frame 12. The angle between the two orifice plates 16 is 90°, which limits the rotation angle of the mounting plate 21. One side of the mounting plate 21 is symmetrically threaded with bolts 26. One end of the bolt 26 is threadedly connected to the orifice plate 16. The bolt 26 cooperates with the orifice plate 16 to fix the use angle of the mounting plate 21 after rotating the mounting plate 21, so as to change the spraying direction of the sprinkler 22.

[0032] In one embodiment, in order to prevent water leakage at the connection, a sealing ring 29 is sleeved on one side of the connection sleeve 27 .

[0033] The utility model is in operation: when it is necessary to spray from above, the mounting plate 21 is rotated to make the mounting plate 21 fit with the orifice plate 16 in the horizontal direction, the mounting plate 21 and the orifice plate 16 are fixed by bolts 26, and the nozzle 22 is directed downward for spraying, the water tank 19 is installed in the mounting tube 15, the water intake pipe 28 enters the water tank 19, and the water tank 19 is connected to the connecting sleeve 27, the blocking cover 18 is connected to the mounting tube 15, and the position of the water tank 19 is fixed. When spraying, the drone body 11 drives the spraying mechanism 20 to move upward, the booster pump 23 is started to pump water from the water tank 19 through the water intake pipe 28, and the water is sprayed through the connecting pipe 24 in cooperation with the spraying pipe 33 and the nozzle 22. When it is necessary to spray a high-rise building sideways, the mounting plate 21 is rotated to make the mounting plate 21 fit with the orifice plate 16 in the vertical direction, and the mounting plate 21 is fixed by bolts 26, so that the nozzle 22 faces the building, and the building can be sprayed from the side for fire extinguishing.

[0034] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
