[0039] The utility model serves as a bridge for underwater robot communication by setting a float communication component 10 for receiving and sending signals. When the float communication component 10 receives a signal, it is transmitted to the underwater robot through the connecting cable 30, so that the underwater robot can complete the operation according to the signal. At the same time, the signal of the underwater robot can also be transmitted to the float communication component 10 through the connecting cable 30, and then transmitted to the terminal by the float communication component 10, thereby completing the signal transmission between the underwater robot and the terminal.

[0040] At the same time, one end of the connecting cable 30 is connected to the floating communication component 10, and the other end passes through the threading port 202, threading groove 203, matching tube 204 and connecting tube 201 on the winding drum 200 of the cable winding assembly 20, and is finally connected to the underwater robot.

[0054] Preferably, the rotational connection between the connecting pipe 201 and the protection box 209 can be sealed by a dynamic sealing method in the prior art.

[0055] In order to further prevent water from entering the driving motor 205 and causing the connecting cable 30 to be unable to be normally collected and released, this embodiment is modified on the basis of the above embodiment. The difference from the above embodiment is that a sealing box 210 is provided on the other side of the mounting part 23, and the sealing box 210 is mounted on the outside of the driving motor 205 and fixedly connected to the mounting part 23.

[0057] Preferably, a limiting member 211 is provided on the protection box 209 , and a through opening 212 is provided on the limiting member 211 .

[0058] One end of the connecting cable 30 needs to pass through the through opening 212 on the limiting member 211 . This method can play a certain limiting and guiding role on the connecting cable 30 , making it easier for the winding reel 200 to collect and release the connecting cable 30 .

[0059] like Figures 8 to 9As shown, in order to conveniently protect the wireless communication module 102 and prevent the wireless communication module 102 from getting wet, this embodiment is modified on the basis of the above embodiment. The difference from the above embodiment is that the float communication component 10 includes a float body 100, a protective cover 101 and a wireless communication module 102, the wireless communication module 102 is arranged on the top of the float body 100, the protective cover 101 is sleeved on the outside of the wireless communication module 102, and is sealed and connected to the float body 100, one end of the connecting cable 30 passes through the float body 100 and is connected to the wireless communication module 102, and the wireless communication module 102 is used to enable the underwater robot to receive and send signals.
