By limiting the friction discs 917 by the limit disc 913, the linkage and decoupling between the first driving fan 905 and the second driving fan 906 can be controlled. The blades of the first driving fan 905 and the second driving fan 906 are in opposite directions. A mounting frame 901 is fixedly installed in the spray cannon barrel 1, and a fixed motor 902 is fixedly installed on one side of the mounting frame 901.

[0046] The specific implementation method is as follows: by providing an air supply component 9, the fixed motor 902 drives the rotating main shaft 908 and the sun gear 911, and the planetary gear 916 and the linkage gear ring 910 are cleverly coordinated to achieve the synchronous reverse rotation of the first drive fan 905 and the second drive fan 906. The torque offset effect generated by the reverse airflow maintains the dynamic balance of the system, effectively solving the airflow deflection problem caused by the operation of a single fan, effectively reducing equipment vibration and energy loss, enhancing the diffusion range and uniformity of the spray, and significantly improving the stability and direction control accuracy of the wind power delivery of the spray cannon 1. At the same time, through the clutch limit mechanism composed of the friction disk 917 and the limit disk 913, the first drive fan 905 and the second drive fan 906 are synchronously rotated in reverse or driven separately, realizing flexible switching between dual-fan and single-fan modes, meeting the dual-fan cooperative supercharging requirements under high-power conditions, and adapting to energy-saving operation in low-load scenarios. The use of the planetary gear 916 structure not only ensures the stability and reliability of power transmission, but also avoids energy loss through the mechanical self-locking mechanism, thereby improving overall energy efficiency.
[0047] The direction adjustment component 2 includes a water supply ring 204, which is connected to one side of the spray barrel 1.

An adjusting screw 209 is connected to the screw seat 208 in a transmission manner. The outer surface of the adjusting screw 209 is rotatably connected to a fixing bracket. One side of the fixing bracket is connected to one side of the water supply ring 204. The adjusting screw 20 9 The end away from the screw seat 208 is connected to a transmission gear 210, and one side of the multiple transmission gears 210 is meshed with a transmission gear ring 211. One side of the transmission gear ring 211 is connected to a drive gear ring 203, and the drive gear ring 203 is rotatably connected to the outer surface of the water supply ring 204. The top of the spray barrel 1 is fixedly installed with a drive motor 201 through a mounting plate.

One side of the atomizing nozzle 206 is connected to a telescopic hose 205, and the end of the telescopic hose 205 away from the atomizing nozzle 206 is connected to the side of the water supply ring 204.
[0048] The specific implementation method is as follows: by setting the direction adjustment component 2, the driving motor 201 drives the atomizing nozzle 206 to deflect around the connecting seat through the driving gear 202, the driving gear ring 203, the transmission gear ring 211, the transmission gear 210, the adjustment screw 209, the screw seat 208 and the direction adjustment connecting rod 207, so that the atomizing nozzle 206 is deflected, thereby changing the spray direction and range of the atomizing nozzle 206. By cooperating with the linkage adjustment mechanism of the multiple atomizing nozzles 206 distributed in an annular shape, the synchronous and precise control of the spray angle of the atomizing nozzle 206 is achieved. The atomizing nozzle 206 deflects outward, which has the advantages of uniform multi-directional coverage and dead-angle atomization diffusion. The atomizing nozzle 206 deflects inward to concentrate the spray to enhance penetration, thereby achieving dynamic matching of the spray shape and coverage area, which can be well applied to various application scenarios such as dust removal and haze reduction, cooling and humidification, and disinfection and epidemic prevention. The driving motor 201 is a self-locking motor with a self-locking function when it stops.
[0049] The flow stabilizing component 8 includes an outer shell 803 arranged at the center position inside the spray cannon barrel 1. The outer surface of the outer shell 803 is connected to a plurality of fixed flow stabilizing plates 801 distributed in a circular array. The other side of the fixed flow stabilizing plate 801 is connected to the inner wall of the spray cannon barrel 1. One side of the outer shell 803 is rotatably connected to a rotating circular block 804. The outer surface of the rotating circular block 804 is connected to a plurality of rotating flow stabilizing plates 802 distributed in a circular array. The other end of the rotating flow stabilizing plate 802 is in contact with the inner wall of the spray cannon barrel 1. A cavity is opened inside the outer shell 803, and an adjustment motor 805 is fixedly installed in the cavity. One end of the output shaft of the adjustment motor 805 extends to the outside of the cavity and is connected to one side of the rotating circular block 804.
[0050] The specific implementation method is: by setting a flow stabilizing component 8, the rotating circle 804 and the rotating flow stabilizing plate 802 are driven to rotate, so that the rotating flow stabilizing plate 802 moves from the position in contact with the fixed flow stabilizing plate 801 to the center position of the two fixed flow stabilizing plates 801, thereby increasing the number of flow stabilizing structures in the spray gun barrel 1, effectively improving the overall flow stabilizing effect on wind force, significantly reducing the generation of air vortices, ensuring that the airflow is more stable and uniform, improving the working efficiency and accuracy of the spray gun, while reducing energy consumption and noise, extending the service life of the equipment, easy operation and strong adaptability, suitable for a variety of working conditions, adjusting the motor 805 to a self-locking motor with a self-locking function when stopped.
[0051] Working principle: When in use, the staff turns on the fixed motor 902 and the external water supply device 4. The external water supply device 4 transports water to the water supply ring 204 through the delivery hose 3, and makes the water sprayed out through the atomizing nozzle 206 after being atomized. During this process, the driving motor 201 rotates, the driving motor 201 drives the driving gear 202 to rotate, the driving gear 202 drives the driving gear ring 203 to rotate, the driving gear ring 203 drives the transmission gear ring 211 to rotate, the transmission gear ring 211 drives the transmission gear 210 to rotate, the transmission gear 210 drives the adjusting screw 209 to rotate, the adjusting screw 209 drives the screw seat 208 to move, the screw seat 208 drives the adjusting connecting rod 207 to move, and the adjusting connecting rod 207 drives the atomizing nozzle 206 to deflect around the connecting seat, so that the atomizing nozzle 206 is deflected, thereby changing the spraying direction and range of the atomizing nozzle 206, thereby meeting different rescue scenarios.
[0052] At the same time, the fixed motor 902 drives the rotating main shaft 908 to rotate, and the rotating main shaft 908 drives the second driving fan 906 to rotate. At this time, the limit plate 913 is driven by the movable cylinder 903 to contact the friction plate 917 located on the lower connecting plate 914, so that the linkage plate 915 is in a locked state. At this time, the fixed motor 902 drives the sun gear 911 to rotate through the rotating main shaft 908, and the sun gear 911 drives the planetary gears 916 to rotate. The planetary gears 916 drive the linkage gear ring 910 to rotate, and the linkage gear ring 910 drives the rotating sleeve 907 to rotate. The rotating sleeve 907 drives the first driving fan 905 to rotate, and the rotation direction of the first driving fan 905 is opposite to that of the second driving fan 906, so that the first driving fan 90 5 and the second driving fan 906 rotate synchronously in the opposite direction and deliver wind force to the spray cannon barrel 1. When the movable cylinder 903 drives the limit plate 913 to move to the side of the upper connecting plate 909, and the limit plate 913 limits the side of the friction plate 917 on the side of the upper connecting plate 909, the linkage gear ring 910 is in a locked state. At this time, the fixed motor 902 drives the sun gear 911 to rotate by rotating the main shaft 908, and the sun gear 911 drives the planetary gears 916 to rotate on the linkage gear ring 910. Since the linkage gear ring 910 is in a locked state, the planetary gears 916 drive the linkage disk 915 to rotate in the limiting slot seat 912. At this time, the first driving fan 905 is locked, and the second driving fan 906 is driven alone to provide wind force.
[0053] When the wind is too strong, the staff starts the adjustment motor 805, and the adjustment motor 805 drives the rotating block 804 to rotate, and the rotating block 804 drives the rotating flow stabilizing plate 802 to rotate, so that the rotating flow stabilizing plate 802, which was originally in contact with the fixed flow stabilizing plate 801, moves to one side, and the rotating flow stabilizing plate 802 rotates to the center position of the two fixed flow stabilizing plates 801, so that the flow stabilizing structures in the spray barrel 1 become more, thereby improving the overall flow stabilizing effect on the wind and avoiding the occurrence of air vortices.
[0054] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
