The first motion mechanisms 3 and the second motion mechanisms 4 includes a plurality of synchronizing wheels 5 wrapped with a flexible track 6. Grooves 19 are provided on a surface of the flexible track 6 and are configured to increase a frictional force. The synchronizing wheels 5 are also connected to the drive mechanism. The cleaning module includes a plurality of brushes 10 which are stretchable and are provided at the other opposite sides of the pressure casing 1. Each of the brushes 10 is provided with a stretchable rod 18, and the stretchable rod 18 is connected to the drive mechanism. The pressure casing 1 is further provided with a searchlight 13, a camera 14 and a sonar sensor 8. The mending module is provided at a bottom of the main body and includes a plurality of mending blocks and a storage device 15 which is configured to store and launch the mending blocks; and the storage device 15 is connected to the drive mechanism. The motion module is further provided with a plurality of waterjet propellers 9 which are arranged at sides of the pressure casing 1. In this embodiment, four first motion mechanisms 3 are symmetrically provided at opposite sides of the pressure casing 1; one second motion mechanism 4 is respectively provided in a middle of two first motion mechanisms 3 at each of the opposite sides of the pressure casing 1; the drive mechanism connected to the storage device 15 and the stretchable rod 18 of each of the stretchable brushes 10 is a hydraulic drive mechanism.

(11) In the invention, the above-mentioned intelligent robot should be used in pairs. During operating, two intelligent robots are slowly placed at inner and outer sides of the net cage, respectively. The two intelligent robots are correlated to each other through sonar sensors 8 to obtain a driving robot and a driven robot, and the control system controls the operation of the drive system so as to control the movement of the synchronizing wheels 5, so that the two intelligent robots are synchronized. When the intelligent robots are moved to a certain position by the water ballast tank, the waterjet propellers 9 are used to finely adjust the position of the intelligent robots. A control system on an aquaculture skiff controls the two intelligent robots through the attraction module and the motion module to conveniently achieve mending and cleaning of the net cage, and self cleaning of the cleaning module in sequence. During the operation, the aquaculture skiff moves with the two intelligent robots. When the cleaning and amending are completed, the two intelligent robots are withdrawn by automatically adjusting ballast water in the water ballast tank to float. The mending of the net cage includes the discovering and the mending of breakages. In a certainly muddy water, the breakage on the net cage is observed using the searchlight 13 and the camera 14 on the pressure casing 1. Through the cooperation of the motion module and the attraction module, the two intelligent robots are moved to the breakage at the same time, and corresponding mending blocks are launched to mend the breakage, respectively. Similarly, through the cooperation of the motion module and the attraction module, the brushes 10 of the cleaning module achieve a targeted cleaning for mussels and water plants on the net cage.

Embodiment 2

(12) This embodiment is based on Embodiment 1. The brushes 10 of the cleaning module are provided at the other opposite sides of the pressure casing 1, and adjacent brushes 10 rotate in an opposite direction. As shown in FIGS. 4 and 5, the cleaning module is further provided with a plurality of circular holes 11 arranged on the pressure casing 1, and a diameter of the circular holes 11 is slightly larger than an outer diameter of the brushes 10. A comb-shaped annular self-cleaning device 12 is correspondingly provided on each of the circular holes 11, so that each of the brushes 10 contacts the annular self-cleaning device 12 during the stretching to remove dirt on each of the brushes 10. The dirt is kept out of the main body to achieve the self cleaning of the brushes 10.

Embodiment 3

(13) The intelligent robot of this embodiment is based on Embodiment 2. The mending blocks are mending blocks 16 with pins or mending blocks 17 with pinholes. When broken holes are found on the net cage, the two intelligent robots are located at the inner and outer sides of the net cage launch two corresponding mending blocks at the same time. As shown in FIGS. 6 and 7, one mending block is a mending block 16 with pins, and the other mending block is a mending block 17 with pinholes, so that the two mending blocks are connected through the connection of pins and pinholes to mend the breakage on the net cage. When the breakage to be mended is large, several mending blocks can be employed to carry out the mending.

Embodiment 4

(14) The above-mentioned intelligent robot should be used in pairs; two intelligent robots are respectively placed at inner and outer sides of the net cage. The two intelligent robots are correlated to each other via sonar sensors 8 and attract each other via a magnetic force to clamp the net cage. Each of the two intelligent robots is provided with a set of first motion mechanisms 3 and second motion mechanisms 4. A traveling path of flexible tracks 6 of the first motion mechanisms 3 is perpendicular to that of the second motion mechanisms 4. When the flexible tracks 6 of the first motion mechanisms 3 of the two intelligent robots walk, the brushes 10 rotate to clean surfaces of the net cage; meanwhile, the flexible tracks 6 of the second motion mechanisms 4 of the two intelligent robots are retracted into the pressure casing 1 along a direction perpendicular to the bottom of each of the two intelligent robots through a stretchable device, so that the friction between the second motion mechanisms and the net cage is eliminated. After a round of cleaning on the net cage, the flexible tracks 6 of the second motion mechanisms 4 of the two intelligent robots are extended to abut each other till flexible tracks 3 of the first motion mechanisms 3 separate with each other and fail to clamp the net cage. The two intelligent robots are moved laterally for a width of each of the two intelligent robots, and the flexible tracks 6 of the second motion mechanisms 4 are withdrawn. Then the flexible tracks 6 of the motion mechanisms 3 used in pairs tightly clamp the net cage to start a next round of cleaning.

(15) The ballast water in the water ballast tank is adjusted by air compression to suspend the intelligent robot in water, avoiding to the damage for the net cage caused by sinking or floating of the intelligent robot.

(16) The above-mentioned embodiments are merely preferred embodiments of the invention, which are only illustrative, and are not intended to limit the scope of the invention.
