[0013] S1: When the ground temperature rises due to a fire in the forest and it is inconvenient for firefighters to enter the forest, the device can be placed in the forest. When the frame moves, the moving wheels will rotate. The rotation of the moving wheels will cause the transmission shaft on the moving wheels to drive the transmission rod to rotate. The rotation of the transmission rod will then drive the sleeve rod to rotate. The rotation of the sleeve rod will cause the cooling spray pipe to rotate in the cover frame. The water flow sprayed from the cooling spray pipe will be sprayed out through the openings provided on the cover frame, and then spray and cool the road surface where the moving wheel has moved, extinguishing the fire on the ground and having the effect of cooling the forest surface, so that firefighters can follow the rear of the frame into the forest without being burned by the fire on the forest surface. The cooling spray pipe is located beside the moving wheel, and while spraying and cooling the forest surface, the water splashed to the ground will contact the surface of the moving wheel, thereby cooling the moving wheel to avoid damage to the moving wheel caused by high temperature and affecting the movement of the moving wheel.

[0014] S2: When the frame moves and the cooling spray pipe rotates to extinguish the fire on the forest surface, due to the high temperature in the forest, in order to prevent the fire from spreading to the part extinguished by the frame, the telescopic rod will drive the cover frame to move horizontally, and the movement of the cover frame will cause the annular groove to drive the limit frame to deflect, and the limit frame will cause the sleeve rod to deflect on the transmission rod to adjust the spray angle of the cooling spray pipe, so that the cooling spray pipe can spray toward the side of the frame, extinguish the fire beside the frame, and prevent the fire from spreading toward the frame;

[0015] S3: When the frame moves, the water in the water tank enters the cooling box through the control valve, and the cooling box discharges the water downward through a number of cooling nozzles to cool the ground at the bottom of the frame, so that the firefighters can follow the frame into the forest. While the frame is moving, the rotating motor will drive the rotating frame to rotate, and the rotation of the rotating frame will drive the connecting frame to rotate, and the connecting frame will drive the swing frame to swing back and forth. The reciprocating swing of the swing frame causes the swing rod to deflect back and forth on the bearing frame, and the deflection of the swing rod will cause the fan blade to move back and forth continuously. When the fan blade When moving toward the outside of the frame, the resistance block at the rear end of the fan blade plate will contact the latch teeth in the arc-shaped slide under the pressure of the torsion spring, and the latch teeth will drive the resistance block to deflect, and the resistance block will drive the bracket to deflect, and the deflection of the bracket will drive the fan blade plate to tilt on the mounting frame, and then when the fan blade plate moves toward the outside of the frame, the tilting movement of the fan blade plate can blow the flame outside the frame outward, thereby preventing the fire from extending in the direction of the frame, and when the fan blade plate moves toward the direction of the frame driven by the swing rod, it can avoid guiding the flame outside the frame in the direction of the frame.

[0017] In the present invention, when the ground temperature rises due to a fire in the forest and it is inconvenient for firefighters to enter the forest, the device can be placed in the forest, and the moving wheels will rotate when the frame moves. The rotation of the moving wheels will cause the transmission shaft on the moving wheels to drive the transmission rod to rotate, and the rotation of the transmission rod will drive the sleeve rod to rotate. The rotation of the sleeve rod will cause the cooling spray pipe to rotate in the cover frame, and the water flow sprayed from the cooling spray pipe will be sprayed through the openings provided on the cover frame, and then the road surface where the moving wheels have moved will be sprayed and cooled, and the fire on the ground will be extinguished to cool the forest surface, so that the firefighters can follow the rear of the frame into the forest without being burned by the fire on the forest surface. The cooling spray pipe is located beside the moving wheel, and the water splashed to the ground while spraying the forest surface to cool it will contact the surface of the moving wheel, so that the moving wheel is cooled to avoid damage to the moving wheel caused by high temperature and affecting the movement of the moving wheel.

[0018] In the present invention, after the frame moves and the cooling spray pipe rotates to extinguish the fire on the forest surface, due to the high temperature in the forest, in order to prevent the fire from spreading to the part of the frame that has been extinguished, the telescopic rod will drive the cover frame to move in the horizontal direction. The movement of the cover frame will cause the annular groove to drive the limit frame to deflect, and the limit frame will cause the sleeve rod to deflect on the transmission rod to adjust the spray angle of the cooling spray pipe, so that the cooling spray pipe can spray toward the side of the frame, extinguish the fire on the side of the frame, and prevent the fire from spreading toward the frame.

[0019] In the present invention, when the frame moves, the water in the water tank enters the cooling box through the control of the control valve, and the cooling box discharges the water downward through a plurality of cooling nozzles to cool the ground at the bottom of the frame, so that the firefighters can follow the frame into the forest. While the frame is moving, the rotating motor drives the rotating frame to rotate, and the rotation of the rotating frame drives the connecting frame to rotate, and the connecting frame drives the swing frame to swing back and forth.

6. The method for using a forest fire extinguisher based on surface cooling according to claim 5 comprises the following steps: S1: When the ground temperature rises due to a fire in the forest and it is inconvenient for firefighters to enter the forest, the device can be placed in the forest. When the frame (1) moves, the moving wheel (11) rotates. The rotation of the moving wheel (11) causes the transmission shaft on the moving wheel (11) to drive the transmission rod (21) to rotate. The rotation of the transmission rod (21) drives the sleeve rod (22) to rotate. The rotation of the sleeve rod (22) causes the cooling spray pipe (24) to rotate in the cover frame (32). The water flow sprayed from the cooling spray pipe (24) passes through the opening ( 34) is sprayed out, thereby spraying and cooling the road surface where the moving wheel (11) moves, extinguishing the fire on the ground and having the effect of cooling the forest surface, so that firefighters can follow the rear of the frame (1) into the forest without being burned by the fire on the forest surface, and the cooling spray pipe (24) is located beside the moving wheel (11), thereby spraying and cooling the forest surface, and the water splashed onto the ground will contact the surface of the moving wheel (11), thereby cooling the moving wheel (11) to prevent the high temperature from damaging the moving wheel (11) and affecting the movement of the moving wheel (11); S2: After the frame (1) moves the cooling spray pipe (24) to rotate and extinguish the fire on the forest surface, the telescopic rod (31) drives the cover frame (32) to move horizontally to prevent the fire from spreading to the part extinguished by the frame (1) because the temperature in the forest is relatively high. The movement of the cover frame (32) causes the annular groove (33) to drive the limit frame (23) to deflect. The limit frame (23) causes the sleeve rod (22) to deflect on the transmission rod (21) and adjust the spray angle of the cooling spray pipe (24), so that the cooling spray pipe (24) can spray toward the side of the frame (1), extinguish the fire on the side of the frame (1), and prevent the fire from spreading toward the frame (1); S3: When the vehicle frame (1) moves, water in the water tank (12) enters the cooling box (54) through the control of the control valve (52), and the cooling box (54) discharges the water downward through a plurality of cooling nozzles (55) to cool the ground at the bottom of the vehicle frame (1), so that the firefighters can follow the vehicle frame (1) into the forest. While the vehicle frame (1) is moving, the rotating motor (61) drives the rotating frame (62) to rotate, and the rotation of the rotating frame (62) drives the connecting frame (63) to rotate, and the connecting frame (63) drives the swing frame (64) to swing back and forth. The swing frame (64) swings back and forth to cause the swing rod (65) to deflect back and forth on the supporting frame (51), and the deflection of the swing rod (65) causes the fan blade (67) to continuously move back and forth. When the fan blade (67) moves toward the vehicle frame (1), the fan blade (67) moves back and forth. When the fan blade plate (67) moves toward the outside of the frame (1), the abutment block (691) at the rear end of the fan blade plate (67) contacts the latching tooth (693) in the arc-shaped slideway (692) under the pressure of the torsion spring, and the latching tooth (693) drives the abutment block (691) to deflect, and the abutment block (691) drives the bracket (68) to deflect, and the deflection of the bracket (68) drives the fan blade plate (67) to tilt on the sleeve frame (66), and then when the fan blade plate (67) moves toward the outside of the frame (1), the tilting movement of the fan blade plate (67) can blow the flame outside the frame (1) outward, thereby preventing the fire from extending in the direction of the frame (1), and when the fan blade plate (67) moves toward the direction of the frame (1) driven by the swing rod (65), it can prevent the flame outside the frame (1) from being guided in the direction of the frame (1).
