[0002] The statements in this section merely mention the background technology related to the present utility model and do not necessarily constitute the prior art.

[0003] The guiding device during the laying of the submarine cable needs to be supported by a guiding frame, which is driven by a motor to lift and lower the submarine cable. However, the motor-driven method to lift and lower the submarine cable causes energy loss, is inconvenient to utilize sea waves, and has insufficient support stability when guiding the submarine cable. During the laying of the submarine cable to the landing section, it may pass through some ecological protection red land or offshore aquaculture farms. If the direction of the submarine cable at sea is not changed according to the actual situation, the friction of the submarine cable will be damaged, and the ecological protection land or offshore aquaculture farms will be damaged.

[0009] As an embodiment, a limiting mechanism for limiting the float is provided outside the column, and the limiting mechanism includes a first limiting plate and a second limiting plate fixed to the column, and the first limiting plate and the second limiting plate are located at two ends of the float.

[0010] As an implementation mode, the first limiting plate is fixed on the top of the column, and the second limiting plate is fixed to the column at the lower part of the lower limiting ring, so that the second limiting plate and the first limiting plate cooperate to limit the float.

[0011] As an embodiment, an auxiliary positioning member is provided at the lower part of the column, and the auxiliary positioning member includes a limiting sleeve movably sleeved at the lower part of the column and a support plate distributed in a ring array welded on the outer surface of the limiting sleeve, a guide tube is welded at the end of the support plate, and an auxiliary insertion rod is movably installed inside the guide tube.

[0012] As an embodiment, the auxiliary positioning member and the pillars located below the auxiliary positioning member are both inserted into the beach.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] First, through the upper limiting ring on the upper part of the float and the lower limiting ring on the lower part of the float, the float, the upper limiting ring and the lower limiting ring cooperate to guide the submarine cable, and the guide roller rotatably installed on the edge of the lower limiting ring makes it easier for the guide roller to support the submarine cable to change the routing direction of the submarine cable.

[0018] Second, the float is installed by rotating on the upper part of the column, and the float has a hollow structure, which makes it easy for the float to float through the sea water in the shallows.

[0019] Thirdly, the float is limited by the limit mechanism of the column external device for limiting the float position, so as to prevent the float from being separated from the column due to sea surface fluctuations, thereby making it easier for the float to guide the submarine cable.
