[0027] It should be noted that, including a slide groove 52 installed in the PU tube fixed sealing round block 3, a rubber pipe 51 is installed in the slide groove 52, and a groove 53 is opened in the rubber pipe 51. When the water flows into the telescopic block 51, the rubber pipe 51 will move into the PU tube fixed sealing round block 3 through the slide groove 53. During the movement, the water originally in the PU tube fixed sealing round block 3 will be squeezed out from the drainage hole 4, thereby achieving the purpose of drainage.

[0028] In the specific implementation process, Figure 5 The circulating oil filling mechanism 7 shown includes an oil inlet hole 71 installed on the upper surface of the shell 1, and a circulating pipe 74 is opened below the oil inlet hole 71. The oil inlet hole 71 is threadedly connected to a first rotating cover 72, and a second sealing ring 73 is installed between the first rotating cover 72 and the circulating pipe 74. An oil outlet hole 75 is opened on the other side of the circulating pipe 74, and the oil outlet hole 75 is threadedly connected to a second rotating cover 76. A third sealing ring 77 is installed between the second rotating cover 76 and the circulating pipe 74.

[0029] It should be noted that an oil inlet hole 71 is installed on the upper surface of the shell 1, and a circulation pipe 74 is provided below the oil inlet hole 71. The oil inlet hole 71 is threadedly connected to a first rotating cover 72, and a second sealing ring 73 is installed between the first rotating cover 72 and the circulation pipe 74.

A third sealing ring 77 is installed between the second rotating cover 76 and the circulation pipe 74. In order to prevent the underwater pressure from damaging the shell 1, the circulation pipe 74 installed inside the shell 1 will keep the internal and external pressures of the shell 1 the same underwater, thereby ensuring the normal use of this device.

[0030] In the specific implementation process, Figure 3 As shown, a first sealing ring 6 is installed at the connection between the housing 1 and the PU tube fixed sealing round block 3.

[0031] It should be noted that a first sealing ring 6 is installed at the connection between the housing 1 and the PU tube fixed sealing round block 3, and the material of the first sealing ring 6 is fluororubber.

[0032] In the specific implementation process, Figure 3 As shown, a closed space 10 is defined between the waterproof layer 9 and the insulating layer 11 .

[0037] It should be noted that a push handle 2 is installed above the housing 1, and the handle 2 can effectively support the staff underwater.

[0038] The working principle of this embodiment is as follows: during specific use, when water flows into the telescopic block 51, the telescopic block 51 will move into the PU tube fixed sealing round block 3 through the slide groove 53. During the movement, the water flow originally in the PU tube fixed sealing round block 3 will be squeezed out from the drainage hole 4 to achieve the purpose of drainage. In order to prevent the underwater pressure from damaging the shell 1, the circulation pipe 74 installed inside the shell 1 will keep the pressure inside and outside the shell 1 the same underwater, thereby ensuring the normal use of this device. When the underwater information device contacts the information receiving hole 12, the underwater information will be transmitted through the communication hose 13 to reach the box body 8 of the communication module. The communication hose 13 is used as a protection device for the information receiving hole 12 and the box body 8 of the communication module. Wireless (M105) or wired (waterproof insulated wire) and other devices can be installed in the box body 8 of the communication module to transmit the underwater information to the surface.
