[0017] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] In a specific embodiment of the present invention, Figures 1 to 3 As shown, a fog cannon adjusting device is specifically disclosed, and the fog cannon adjusting device is arranged at the upper end of the fog cannon body 1. The fog cannon adjusting device includes an adjusting nozzle 2, a ring 3 and an electric push rod 4. The adjusting nozzle 2 includes a bottom plate 21 and three arc plates 22. The bottom plate 21 is fixedly connected to the top of the fog cannon body 1. A hole connected to the fog cannon body 1 is opened on the bottom plate 21; the three arc plates 22 are sequentially arranged on the bottom plate 21 along the circumferential direction to form a nozzle.

[0019] The bottom of the outer wall of each arc plate 22 is movably connected to the bottom plate 21; the arc plate 22 and the bottom plate 21 are movably connected via a connecting mechanism, the connecting mechanism includes a fixing member 6 and a connecting member 7, the connecting member 7 is rotatably connected to the fixing member 6, the connecting member 7 is fixed to the bottom of the outer wall of the arc plate 22, and the fixing member 6 is fixed to the bottom plate 21.

[0020] A connecting plate 5 is provided on the outer wall of each arc plate 22, and the connecting plate 5 is welded and fixed to the arc plate 22. A waist-shaped hole is provided on the connecting plate 5, and the ring 3 is inserted into the waist-shaped hole, and the ring 3 slides in the waist-shaped hole.

[0021] The bottom plate 21 is also provided with a plurality of auxiliary fixing plates 8 for carrying the circular ring 3. The auxiliary fixing plates 8 are provided with waist-shaped holes perpendicular to the end surface of the bottom plate 21. The circular ring 3 is inserted into and slides in the waist-shaped holes. The number of the auxiliary fixing plates 8 is equal to that of the connecting plates 5. The auxiliary fixing plates 8 and the connecting plates 5 are alternately arranged along the same circumference.

[0022] The electric push rod 4 is tilted, and an angle is formed between the electric push rod 4 and the vertical line of the fog cannon body 1, and the range of the angle is 20-45°. One end of the electric push rod 4 is connected to the fog cannon body 1, and the other end is connected to the ring 3. There are two electric push rods 4, and the two electric push rods 4 are symmetrically arranged on both sides of the fog cannon body 1. A push rod support 9 is fixedly arranged on the outer side wall of the fog cannon body 1, and the electric push rod 4 is movably connected to the push rod support 9; a fixed bracket 10 is fixedly arranged on the ring 3, and the electric push rod 4 is fixedly connected to the fixed bracket 10.

[0023] The electric push rod 4 pushes the ring 3 to slide in the waist-shaped hole. When the electric push rod 4 is in a normal contraction state (such as Figure 2 As shown), the electric push rod 4 drives the ring 3 to be placed at the bottom of the arc plate 22, and the three arc plates 22 are tilted outward to adjust the nozzle 2 to be in the open state; when the electric push rod 4 is extended (as shown Figure 1 As shown), the electric push rod 4 pushes the ring 3 to drive the three arc plates to swing inward, and the side edges of the three arc plates 22 are fitted together to form a conical cylinder nozzle.

[0024] The working process of the present invention is as follows: the battery of the fog cannon sanitation vehicle provides the power source of the electric push rod 4. Under the action of the electric push rod 4, the ring 3 moves in the connecting plate 5 and the auxiliary fixing plate 8. When the electric push rod 4 is in a normal state, the electric push rod 4 drives the ring 3 to be placed at the bottom of the waist-shaped hole. The three arc plates 22 are driven by the connecting plate 5 and swing outward at the same time through the rotating shaft 7, so that the regulating nozzle 2 is in an open state, thereby realizing the short-range or low-place flushing and maintenance of the fog cannon; when the electric push rod 4 is in a maximum stretching state, the three arc plates 22 are driven by the connecting plate 5 and swing inward at the same time through the rotating shaft 7. The sides of the three arc plates 22 are fitted together to form a conical cylinder, so that the regulating nozzle 2 is in a closed state, thereby realizing the long-range or high-place flushing and maintenance of the fog cannon. Through this device, the long-range high-place flushing and short-range low-place flushing functions of the fog cannon sanitation vehicle can be realized.

[0025] The above disclosure is only a preferred embodiment of the present invention, which certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope of the present invention.
