[0029] A bracket is provided on the gear plate 2 . The bracket is U-shaped and includes a bottom plate 5 and a first side plate 6 and a second side plate 7 vertically arranged on the bottom plate 5 . Specifically, the bracket opening is arranged upward, and the bottom plate 5 of the bracket is fixedly connected to the gear plate 2 .

[0030] The bracket is provided with a reel 8, specifically, the reel 8 is located between the first side plate 6 and the second side plate 7, the reel 8 is cylindrical in shape and hollow inside. The reel 8 is provided with an axial hole at the center of the end surface (i.e., the first end surface) of the first side plate 6, in which a transfer shaft 10 is rotatably mounted through a second bearing 9, the transfer shaft 10 is cylindrical in shape, and the section of the transfer shaft 10 located outside the reel 8 passes through the first side plate 6 and is fixedly connected to the first side plate 6.

[0032] like Figure 4 As shown, the section of the adapter shaft 10 located inside the reel 8 is rotatably covered with a sleeve 12, and the sleeve 12 is fixedly connected to the reel 8, that is, the reel 8 can synchronously drive the sleeve 12 to rotate while rotating. A plurality of oil injection holes 13 are arranged on the wall of the sleeve 12 at intervals along the length direction. In this embodiment, three oil injection holes 13 are preferably arranged.

The hydraulic oil is injected from the oil injection pipe 15 into the corresponding annular oil injection groove 14, and then into the corresponding oil injection hole 13. Since the sleeve 12 is rotatable, there is a gap between the sleeve 12 and the adapter shaft 10. In order to prevent the hydraulic oil in the annular oil injection groove 14 from leaking out of the gap, a sealing ring 16 is provided on both sides of each annular oil injection groove 14 to play a role of rotary sealing. In addition, an oil collection pipe 17 is provided in the adapter shaft 10 along the length direction.

[0033] An oil pipe fixing flange 18 is fixedly provided inside the reel 8, and an oil collection pipeline 19 and three oil injection pipelines 20 are fixedly installed on the oil pipe fixing flange 18.

The oil injection path of the oil injection line is the oil injection pipeline 15, the annular oil injection groove 14, the oil injection hole 13, the oil injection pipeline 20 and the oil injection hose 223 in sequence. In addition, the flow of each oil injection line can be controlled as needed. During the operation of the oil suction machine, the oil spill on the sea surface passes through the oil collection hose 222, the oil collection pipeline 19 and the oil collection pipeline 17 in sequence, and finally enters the oil storage device. During the oil collection process, the pipeline assembly can also be automatically retracted and released according to the oil collection process, which is convenient to use.
