[0022] like Figures 1 to 4 As shown, a rotating motor 11 is fixedly installed at the bottom end of the rotating frame 5, and a driving gear 12 is fixedly installed at the output end of the rotating motor 11 through the rotating frame 5. A gear ring 13 is fixedly installed on the upper surface of the fixed ring 3, and the gear ring 13 is meshed and connected with the driving gear 12.

[0023] The driving gear 12 rotates by the operation of the rotating motor 11 , and the engagement of the gear ring 13 with the driving gear 12 drives the rotating frame 5 to rotate along the outer track of the radome body 1 .

[0025] When the rotating frame 5 rotates along the outer track of the radome body 1, the annular slider 4 limits the rotation of the bottom end of the rotating frame 5, and the top of the rotating frame 5 is supported and limited by the mutual rotation of the fixing rod 15 and the fixing tube 14.

[0026] like Figures 1 to 4 As shown, the top and bottom of the rotating frame 5 are rotatably installed with a first fixed pulley 16 and a second fixed pulley 17 respectively, and a lifting motor 18 is fixedly installed on the outer side of the lower end of the rotating frame 5 corresponding to the position of the second fixed pulley 17, and the output end of the lifting motor 18 is fixedly connected to one end of the second fixed pulley 17, and a transmission rope 19 is frictionally installed between the first fixed pulley 16 and the second fixed pulley 17, and the transmission rope 19 is fixedly connected to the moving frame 8.

[0027] The operation of the lifting motor 18 will drive the second fixed pulley 17 to rotate, and the friction between the transmission rope 19 and the first fixed pulley 16 and the second fixed pulley 17 will drive the transmission rope 19 to move, thereby driving the movable frame 8 to slide along the trajectory of the positioning groove 7, and the forward and reverse rotation of the lifting motor 18 will drive the water-absorbing sponge 10 to absorb the water on the outside of the radar cover body 1.

[0035] When the device is in use, the driving gear 12 rotates through the operation of the rotating motor 11, and the engagement of the gear ring 13 with the driving gear 12 will drive the rotating frame 5 to rotate along the outer track of the radome body 1. At the same time, the operation of the lifting motor 18 will drive the second fixed pulley 17 to rotate, and the friction between the transmission rope 19 and the first fixed pulley 16 and the second fixed pulley 17 will drive the transmission rope 19 to move, thereby driving the moving frame 8 to slide along the track of the positioning groove 7, and the forward and reverse rotation of the lifting motor 18 will drive the water-absorbing sponge 10 to absorb the water on the outer side of the radome body 1, so as to clean the surface of the radome body 1.
