the reset mechanism (8) comprises a driving plate (81), a sliding column (82), a sliding barrel (83), a second spring (84), a pressing plate (85) and a connecting shaft (86), the surface of the rotating shaft (73) is fixedly connected with the driving plate (81), the side wall of the driving plate (81) is fixedly connected with the pressing plate (85) with the inverted U-shaped structure in section, the bottom of the pressure plate (85) rotates the connecting shaft (86), the top of the sliding column (82) is rotatably connected with the sliding column (82), the sliding column (82) is connected with the inner part of the sliding cylinder (83) on the surface of the fixed plate (41) in a sliding way, the second spring (84) is placed in the sliding barrel (82), the top of the second spring (84) is abutted against the bottom of the sliding column (82), and one end of the driving plate (81) is fixedly connected with the spray head (51);

when the water tank is used, firstly, when the water in the water tank (2) is insufficient, the cover (31) is rotated to open the connecting column (33), so that water can be injected into the water tank (2) to continuously irrigate the bridge, the rotation of the wheels (15) is realized after the engine (13) is started, and the handle (11) is held by a hand during irrigation to control the walking direction of the whole structure; then, after the first switch (63) is powered on, the rotating rod (93) rotates to rotate the rotating plate (91) at three hundred sixty degrees clockwise, the linkage plate (92) horizontally and reciprocally pulls the swinging plate (77), and finally the swinging plate (77) drives the toothed plate (74), the surface of the fixed plate (41) is welded into a fixed frame (78) with an inverted U-shaped structure, the surface of the fixed frame (78) is rotationally connected with the swinging plate (77) with a fan-shaped structure, the top of the swinging plate (77) is fixed into a sliding rail (76) with an arc-shaped structure, the side wall of the sliding rail (76) is provided with a sliding groove (75), the toothed plate (74) with the arc-shaped structure is slidably connected inside the sliding groove (75), the gear (72) is meshed with the toothed plate (74), after the driving mechanism (9) is powered on, the swinging plate (77) horizontally swings, and the toothed plate (74) further reciprocates inside the sliding groove (75), therefore, the gear (74) rotates the rotating shaft (73) clockwise and anticlockwise, the rotating rod (93) rotates clockwise and anticlockwise and then the driving plate (81) moves up and down in the movable groove (42), and further, when the integral structure walks, the spray head (51) moves in an arc shape to uniformly spray water on the bridge, so that water resources are saved; finally, the second switch (64) is opened to realize the movement of the electric push rod (56), the electric push rod (56) pushes the wrench (55) to realize the piston (59b) to push the water in the water bin (59a) to the inside of the connecting pipe (53), because the internal pressure of the water tank (2) is higher, the internal water of the water bin (59a) can not flow to the inside of the water tank (2) from the suction pipe (57), the internal water of the connecting pipe (53) is sprayed to the spray head (51) from the spray pipe (52) to realize the irrigation of the bridge, when the electric push rod (56) leaves the wrench (55), the first spring (59) is reset to slide the piston (59b) to one end of the water cylinder (58) away from the suction pipe (57), the air outlet hole (32) on the top of the cover (31) sucks air to suck the water in the water tank (2) from the suction pipe (57) to the interior of the water bin (59a) to wait for the next pushing of the wrench (55) to realize continuous irrigation.

2.
