[0058] Embodiment 4

[0059] like Fig. 9 and Fig.10 As shown, Fig. 9 is a structural side view of the water tank; Fig.10 It is a structural front view of the water tank.

[0061] The first reinforcing rod 11 and the third reinforcing rod 13 are arranged in parallel, and the setting height of the first reinforcing rod 11 is lower than the setting height of the third reinforcing rod 13, so that the parallel second reinforcing rod 12 and the fourth reinforcing rod 14 are arranged obliquely, and the viewing angle portion 4 is arranged on the first reinforcing rod 11 to form the head of the curtain wall cleaning drone of the present invention, and the nozzle 33 end of the cleaning pipe 32 is arranged corresponding to the first reinforcing rod 11.

[0065] Under the tilting action of the second reinforcing rod 12 and the fourth reinforcing rod 14, when the water tank 2 is placed on the second reinforcing rod 12 and the fourth reinforcing rod 14, it will slide toward the viewing angle 4 under the action of its own gravity, and the water tank 2 will be initially fixed on the fuselage frame 1 under the positioning action of the snap-in groove 41. The positioning contact surface 211 and the two groove walls of the snap-in groove 41 are inclined, which is more conducive to guiding the front end surface of the water tank 2 to the bottom surface of the snap-in groove 41, thereby ensuring that the fixed state of the water tank 2 is stable.

[0066] Generally, the two sides of the water tank 2 are symmetrically provided with stabilizing blocks 22, which are provided below the corresponding support plates 355, and the extending direction of the stabilizing blocks 22 is consistent with the inclination direction of the bottom surface of the support block 21, and the thickness of the stabilizing blocks 22 gradually decreases in the direction away from the bottom surface of the support block 21.
