[0050] See Figures 1 to 3 This embodiment provides a water spraying device for a sprinkler truck, including a support frame 10, a main nozzle 20, a nozzle assembly 30, and a drive mechanism 40.

[0051] The support frame 10 is connected to the bottom of the truck head. Specifically, the support frame 10 is located at the bottom of the truck head, in front of the front wheels of the sprinkler truck.

[0052] The main nozzle 20 is rotatably connected to the support frame 10. The main nozzle 20 is horizontally positioned and contains a high-pressure water flow. The main nozzle 20 is positioned horizontally relative to the water truck. Specifically, both ends of the main nozzle 20 are located on the sides of the two front wheels of the water truck. The nozzle assembly 30 is connected to the main nozzle 20 and is used to spray water outwards (i.e., spray water downwards or forwards simultaneously). The drive mechanism 40 is used to drive the main nozzle 20 to rotate.

[0053] In this embodiment, during the normal forward movement of the sprinkler truck, the external water pipe connected to the main nozzle 20 fills the main nozzle 20 with high-pressure water. The main nozzle 20 rotates, and the nozzle assembly 30 connected to the main nozzle 20 sprays water forward and to both sides simultaneously. When there are pedestrians on the roadside, the main nozzle 20 rotates, and the nozzle assembly 30 rotates. After the nozzle assembly 30 rotates horizontally, its end gradually tilts downward, greatly reducing the coverage area of ​​the water sprayed by the nozzle assembly 30, thereby avoiding water splashing onto pedestrians and ensuring that the water spraying operation can continue.

[0054] In one embodiment, the water spraying device of the sprinkler truck further includes an inlet pipe 50 and a sealed pipe 51 closed at one end. The main nozzle 20 includes a central pipe 21 and two connecting pipes 22.

[0055] The central tube 21 is connected to the nozzle assembly 30. Two connecting tubes 22 are connected to both ends of the central tube 21, respectively.

[0056] The inlet pipe 50 is rotatably connected to and communicates with one of its connecting pipes 22 at the end furthest from the central pipe 21, and the sealed pipe 51 is rotatably connected to and communicates with the other connecting pipe 22 at the end furthest from the central pipe 21; the drive mechanism 40 is used to drive the two connecting pipes 22 to rotate. The rotation center line of the sealed pipe 51 and the connecting pipe 22 is the same as the rotation center line of the central pipe 21.

[0057] In this embodiment, the inlet pipe 50 is used to input high-pressure water flow, and the connection pipe 22 and the inlet pipe 50, as well as the connection pipe 51, are all dynamically sealed. The drive mechanism 40 drives the connection pipe 22 to rotate, thereby causing the nozzle assembly 30 on the middle pipe 21 to simultaneously face forward or tilt downward, thus changing the coverage area of ​​the water sprayed from the nozzle assembly 30.

[0058] In one embodiment, the drive mechanism 40 includes a sleeve 41, a mounting bracket 42, a motor 43, a rotating shaft 44, and a drive tube 45.

[0059] The sleeve 41 is coaxially rotatably mounted on the middle pipe 21. The mounting bracket 42 is connected to the sleeve 41. The motor 43 is connected to the mounting bracket 42. The rotating shaft 44 is rotatably connected to the mounting bracket 42, and its end is coaxially connected to the output end of the motor 43. The upper end of the drive pipe 45 is rotatably connected to the support frame 10, and its lower end is coaxially mounted on the outside of the rotating shaft 44. The inner wall of the drive pipe 45 is threadedly connected to the outer wall of the rotating shaft 44. The support frame 10 is located between the inlet pipe 50 and the sealed pipe 51.

[0060] In this embodiment, the motor 43 rotates through the rotating shaft 44, thereby enabling the rotating shaft 44 to move axially within the drive tube 45, which in turn causes the water inlet pipe 50 and the sealed pipe 51 on opposite sides of the middle tube 21 and the connecting pipe 22 to rotate, thereby enabling the nozzle assembly 30 on the middle tube 21 to spray water forward or downward.

[0061] In one embodiment, the gun head assembly 30 includes a first gun head 31 and two second gun heads 32.

[0062] The first nozzle 31 is connected to the middle part of the central tube 21. The ends of the second nozzle 32 are connected to flexible tubes 33. The two flexible tubes 33 are connected to the two ends of the central tube 21 respectively.

[0063] The axes of the first gun head 31 and the second gun head 32 are parallel to each other and both perpendicular to the axis of the central tube 21. The second gun head 32 is rotatably connected to the central tube 21, and the drive mechanism 40 rotates the second gun head 32.

[0064] In this embodiment, the first nozzle 31 can spray water directly forward, and the two second nozzles 32 can spray water directly forward from both ends of the central pipe 21. The sprayed water spreads and covers the road. In addition, the drive mechanism 40 can drive the two second nozzles 32 to rotate at a certain angle, so that the second nozzles 32 can spray water towards the left front and right front of the sprinkler truck, thereby expanding the coverage area of ​​the sprayed water.

[0065] In one embodiment, the water spraying device of the sprinkler truck further includes two connecting rods 52. The two connecting rods 52 correspond to two second nozzles 32 respectively, and the middle part of the connecting rod 52 is rotatably connected to the central tube 21. One end of the connecting rod 52 is connected to the outer wall of the second nozzle 32.

[0066] The drive mechanism 40 also includes a connecting shaft 46 and two guide posts 47.

[0067] The connecting shaft 46 is connected to the support frame 10, and the axis of the connecting shaft 46 is located on the rotation center line of the central tube 21. Two guide posts 47 are coaxially connected to the connecting shaft 46, and the two guide posts 47 correspond to the two connecting rods 52 respectively.

[0068] A spiral groove 48 is formed on the outer wall of the guide post 47. Specifically, the spiral groove 48 is a groove formed along a spiral trajectory. The end of the connecting rod 52 away from the second nozzle 32 is inserted into the corresponding spiral groove 48 and is fitted with it with a clearance. When the middle tube 21 rotates downward relative to the sealed tube 51, the end of the connecting rod 52 located in the spiral groove 48 is guided by the spiral groove 48 and approaches the sealed tube 51 or the water inlet tube 50 on the same side.

[0069] In this embodiment, when it is necessary to reduce the coverage area of ​​the water sprayed from the first nozzle 31 and the second nozzle 32, the middle tube 21 is adjusted to rotate downward, so that the first nozzle 31 and the second nozzle 32 face the road surface. At this time, the connecting rod 52 rotates on the middle rod, and the end of the connecting rod 52 away from the second nozzle 32 is guided by the spiral groove 48 to approach the sealed tube 51 or the water inlet pipe 50 on the same side. This causes the second nozzle 32 at the other end of the connecting rod 52 to return to its original position. After the second nozzle 32 is coaxial with the hose 33, it faces the road surface downward and is no longer tilted.

[0070] Numerous specific details are set forth in this specification. However, it will be understood that embodiments of this invention may be practiced without these specific details. In some instances, well-known methods, structures, and techniques have not been shown in detail so as not to obscure the understanding of this specification.

[0071] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
