[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] like Figures 1 to 6 As shown, a fog cannon vehicle with easy replacement of fan blades includes a vehicle body 1 and a fog cannon mechanism installed at one end of the vehicle body 1, the fog cannon mechanism includes a fan assembly 2, a gun barrel 3 and a drive motor 4, one end of the fan assembly 2 is connected to the output end of the drive motor 4, the other end of the fan assembly 2 is connected to the gun barrel 3, one end of the gun barrel 3 is fixedly connected with a high-pressure nozzle 8, the high-pressure nozzle 8 is connected to an external water tank, a support frame 5 is installed under the fan assembly 2, the gun barrel 3 and the drive motor 4, and the bottom of the support frame 5 is connected to one end of the vehicle body 1.

[0025] like Figure 1 As shown, a fog cannon vehicle that is easy to replace fan blades in the utility model is similar to the structure of the existing fog cannon vehicle, such as the fog cannon vehicle disclosed in the patent publication number CN210357680U. The main improvement of the utility model is to make the fog cannon vehicle always maintain the best working state, such as Figures 1 to 6As shown, in the utility model, a fog cannon vehicle with easy replacement of fan blades is used. When in use, the external water tank at one end of the vehicle body 1 transports water to the high-pressure nozzle 8, and the water is sprayed out to form water mist. The driving motor 4 drives the fan assembly 2 to rotate. The wind force generated by the fan assembly 2 blows the water mist in the gun barrel 3 located at the front end of the fan assembly 2, so that the water mist covers and floats forward, cleans and purifies the air, and alleviates haze. When the fan blades 204 need to be replaced, the support frame 5 at the bottom of the gun barrel 3 and the vehicle body 1 are separated, and then the fan assembly 2 is replaced. The support frame 5 at the bottom of the component 2 is separated from the vehicle body 1, and the U-shaped connecting plate 6 between the fan assembly 2 and the barrel 3 is removed so that the fan assembly 2 and the barrel 3 can be separated, and the fixing ring 7 on the outside of the driving motor 4 and the rotating rod 203 in the fan assembly 2 is loosened, and the rotating rod 203 and the driving motor 4 are separated. The fan assembly 2 can be completely removed from the vehicle body 1, and the rotating rod 203 and the fan blades 204 can be repaired, inspected or replaced to keep the fog cannon vehicle in the best working condition at all times.

[0026] like Figures 1 to 4 As shown, the fan assembly 2 includes a shell 201, a rotating rod 203 and fan blades 204. The rotating rod 203 is provided inside the shell 201, and the fan blades 204 are fixedly connected to the outside of the rotating rod 203. One end of the rotating rod 203 is embedded and connected with the output end of the driving motor 4.

[0027] Specifically, through this setting, the rotating rod 203 is connected to the output end of the driving motor 4, and the driving motor 4 also provides a supporting effect for the rotating rod 203, so that the rotating position can be kept fixed in the shell 201, avoiding the fan blades 204 and the inner wall of the shell 201 from scratching.

[0028] like Figure 5 As shown, the output end of the driving motor 4 is fixedly connected to a rotating shaft 401 , one end of the rotating shaft 401 is provided with a slot 402 , and one end of the rotating rod 203 is fixedly connected to a plug-in strip 205 that is engaged with the slot 402 .

[0029] Specifically, this arrangement can strengthen the connection between the rotating rod 203 and the rotating shaft 401, so that the rotating rod 203 and the rotating shaft 401 maintain a vertical connection, and the fan blades 204 remain in the middle position in the shell 201. When the driving motor 4 drives the fan blades 204 to rotate, the fan blades 204 avoid tilting, thereby maintaining stable wind output.

[0030] like Figure 5 As shown, a fixing collar 7 is sleeved at the connection between the rotating rod 203 and the rotating shaft 401 , and an external bolt passes through the fixing collar 7 , and the rotating rod 203 and the rotating shaft 401 are fixedly connected by the external bolt.

[0031] Specifically, by setting up the fixing ring 7, the stability of the connection between the rotating rod 203 and the rotating shaft 401 can be improved, and the connection between the rotating rod 203 and the rotating shaft 401 can be prevented from loosening due to long-term rotation. Under the premise that the parts in the fan assembly 2 are easy to replace, the fan assembly 2 can stably provide wind power to the barrel 3.

[0032] like Figures 1 to 5 As shown, a connecting ring 202 is installed at one end of the shell 201, and a bottom ring 301 is installed at the bottom of the barrel 3. The surface of the connecting ring 202 and the surface of the bottom ring 301 are fitted and connected, and the surface of the connecting ring 202 and the bottom ring 301 are equal in thickness and diameter. A U-shaped connecting plate 6 is installed at the connection between the connecting ring 202 and the bottom ring 301, and external bolts pass through the U-shaped connecting plate 6. The connecting ring 202 and the bottom ring 301 are fixedly connected by external bolts.

[0033] Specifically, through this arrangement, the fan assembly 2 and the gun barrel 3 are fixed together by the U-shaped connecting plate 6. After the connecting ring 202 and the bottom ring 301 are connected together, the inner wall of the U-shaped connecting plate 6 and the two sides of the connecting ring 202 and the bottom ring 301 are fitted together, so that the connecting ring 202 and the bottom ring 301 are fixed together by the U-shaped connecting plate 6, and then the connection stability is further improved by external bolts. Multiple U-shaped connecting plates 6 are fixed on the outside of the connecting ring 202 and the bottom ring 301 to improve the stability of the connection between the fan assembly 2 and the gun barrel 3.

[0034] like Figure 6 As shown, a protection grille 9 is installed at the bottom of the housing 201 , and a rotating rod channel 901 is opened at the center of the protection grille 9 .

[0035] Specifically, by setting up the protective grille 9, foreign objects can be prevented from entering the fan assembly 2, causing damage to its internal parts and affecting the normal operation of the fan assembly 2, and the rotating rod 203 can pass through the rotating rod channel 901 and connect to the drive motor 4, while protecting the fan assembly 2 without affecting the rotation of the fan blades 204.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
