[0018] The water-based fire extinguisher disclosed herein can achieve the following technical effects:
[0019] This disclosure provides a water-based fire extinguisher, comprising a trolley, a fire extinguisher, a first motor, a first support plate, an electric push rod, a second support plate, a second motor, a third support plate, and an electric gripper. The trolley includes a platform parallel to the ground, which supports related components of the mounting device. The fire extinguisher is detachably mounted on the trolley and includes a spray nozzle for spraying foam to extinguish the fire. The first motor is mounted on the bottom surface of the platform, with its rotating end passing through and perpendicular to the platform, providing driving force for rotational movement. The first support plate is mounted on the rotating end of the first motor and located above the platform, rotating under the drive of the first motor. The electric push rod is mounted on the top surface of the first support plate, with its moving end perpendicular to the platform, providing driving force for linear movement. The second support plate is mounted on the moving end of the electric push rod and moves up and down under its drive. The second motor is mounted on the second support plate, with its rotating end passing through the plate and parallel to the vehicle body. It provides driving force to achieve linear movement.

[0020] In use, after the electric gripper clamps the spray gun, controlling the first motor will rotate the first support plate. This ultimately rotates the spray gun horizontally, allowing for angle adjustment. Controlling the electric push rod will raise or lower the second support plate, ultimately raising or lowering the spray gun, thus adjusting the height of the electric push rod. Controlling the second motor will rotate the third support plate, ultimately rotating the spray gun vertically, allowing for angle adjustment. Therefore, the elevation angle of the spray gun can also be adjusted, allowing for direct targeting of the fire and improving extinguishing effectiveness. Furthermore, after the electric gripper releases the spray gun, it can be handheld for extinguishing small fires.

[0039] Combination Figures 1 to 6As shown, this embodiment of the present disclosure provides a water-based fire extinguisher 20, including a cart 10, a fire extinguisher 20, a first motor 30, a first support plate 40, an electric push rod 50, a second support plate 60, a second motor 70, a third support plate 80, and an electric gripper 90. The cart 10 includes a platform 11 parallel to the ground, which supports related components of the mounting device. The fire extinguisher 20 is detachably mounted on the cart 10 and includes a spray gun 21 for spraying foam to extinguish a fire. The first motor 30 is mounted on the bottom surface of the platform 11, with its rotating end passing through and perpendicular to the platform 11, providing driving force to achieve rotational movement. The first support plate 40 is mounted on the rotating end of the first motor 30 and located above the platform 11, rotating under the drive of the first motor 30. An electric push rod 50 is mounted on the top surface of the first support plate 40. The moving end of the electric push rod 50 is perpendicular to the vehicle plate 11 and provides driving force to achieve linear movement. A second support plate 60 is mounted on the moving end of the electric push rod 50 and moves up and down under the drive of the electric push rod 50. A second motor 70 is mounted on the second support plate 60. The rotating end of the second motor 70 passes through the second support plate 60 and is parallel to the vehicle plate 11, providing driving force to achieve linear movement. A third support plate 80 is mounted on the rotating end of the second motor 70 and rotates under the drive of the second motor 70. An electric gripper 90 is mounted on the third support plate 80 and is used to clamp or release the spray gun 21.
[0040] This embodiment of the water-based fire extinguisher 20 provides the following features: When the electric gripper 90 clamps the spray gun 21, controlling the first motor 30 to operate rotates the first support plate 40. This ultimately rotates the spray gun 21 horizontally, allowing for angle adjustment. Controlling the electric push rod 50 raises or lowers the second support plate 60, ultimately raising or lowering the spray gun 21, thus adjusting the height of the electric push rod 50. Controlling the second motor 70 rotates the third support plate 80, ultimately rotating the spray gun 21 vertically, allowing for angle adjustment. Therefore, the elevation angle of the spray gun 21 can also be adjusted, allowing for direct fire suppression and improved extinguishing effectiveness. Furthermore, when the electric gripper 90 releases the spray gun 21, it can be held by hand for fire suppression, making it suitable for small fires.
[0041] Optionally, combined Figure 1 , Figure 4 and Figure 5 As shown, the cart 10 also includes wheels 12 and handles 13. The wheels 12 are respectively installed at the four corners of the cart platform 11, and are used to abut against the ground. The handles 13 are installed on the top surface of the cart platform 11, and the fire extinguisher 20 is detachably installed on the handles 13.
[0042] In this embodiment, the wheels 12 at all four corners are used to abut against the ground, facilitating the movement of the entire device. The handles 13 are used for gripping, allowing for manual pushing of the entire device.
[0043] Optionally, combined Figure 1 , Figure 4 and Figure 5 As shown, the fire extinguisher 20 also includes a carbon steel canister 22, a valve 23, and a hose 24. The carbon steel canister 22 is detachably mounted on the handle 13 and contains AFFF aqueous film-forming extinguishing agent and nitrogen-generated foam. The valve 23 is mounted on top of the carbon steel canister 22 for releasing the extinguishing agent. The hose 24 is installed between the valve 23 and the nozzle 21 for delivering the extinguishing agent.
[0044] In this embodiment of the present disclosure, after the valve 23 is opened, the extinguishing agent in the carbon steel tank 22 can be delivered to the interior of the spray gun 21 through the hose 24, and finally sprayed out through the spray gun 21 to extinguish the fire.
[0045] Optionally, combined Figure 1 , Figure 4 and Figure 5 As shown, the fire extinguisher 20 also includes a fixed clamp 25 and a movable clamp 26.
