One end of the data line 31 is connected to the detecting element 2 by a wire, and the other end is provided with a floating ball 32. The density of the levitated ball 32 is lower than the density of the body of water in which it is located.
The data line 31 is wound on the telescopic mechanism 33 and automatically extends and retracts in the water body, so that the floating ball 32 is kept on the surface of the water body. The telescopic mechanism 33 is arranged at the top of the explosion-proof box body 1, the suspension ball 32 is kept on the water surface A under the buoyancy of the water body, and the signal transmitting unit is arranged in the suspension ball 32 and used for interacting the detection data of the detection element 2 with the outside.
Under the rewinding force of the telescopic mechanism 33, the part of the data line 31 in the water is kept as straight as possible to avoid an excessive movement range of the floating ball 32 on the water surface a.
The top of telescopic mechanism 33 is provided with arc support 34, and the arcwall face is towards surface of water A. The arc support bracket 34 is provided with a through hole for passing through the data line 31. The levitating ball 32 is positioned above the arcuate support 34. The arc-shaped support frame 34 is mainly used for preventing the floating ball 32 from impacting the telescopic mechanism 33 when being recovered, and meanwhile, the data wire 31 also penetrates through the surface where the telescopic mechanism 33 is connected with the explosion-proof box body 1 and extends into the explosion-proof box body 1.
