Description

Technical Field

[0001] The utility model belongs to the technical field of hydraulic ship locks, in particular to a hull protection mooring hook. Background Art

[0002] Ship lock refers to a type of "navigation structure". In natural rivers, due to the regulation of flow and channelization of navigation, and in canals due to the limitations of terrain conditions and water surface slope, a stepped longitudinal section must be formed to form a concentrated water surface drop, so special navigation structures must be used to allow ships to pass through the drop directly; ship lock mooring hooks are devices used inside the ship lock to fix passing ships. During the process of filling and draining the lock chamber, since the ship is floating in the water, the rising or falling water flow will have an impact on the ship in the lock chamber. At this time, the mooring hook plays the role of fixing the ship; mooring hooks are generally arranged at equal intervals along the height of the lock wall, and are designed to be able to withstand the shape and size of the predetermined load to meet the use requirements. Its structure should be simple, strong, durable, and easy to maintain. At the same time, the mooring hook should also be equipped with a reliable locking device to ensure that it will not be accidentally loosened when bearing loads. In addition, the mooring hook should have an obvious mooring hole for easy mooring.

[0003] In contrast, a Chinese patent with authorization announcement number CN217174688U discloses a shear-type cable release device for a floating mooring post of a ship lock, comprising a mooring rod, a shear shaft, a rotating shaft and a mooring rod support frame; the shear shaft and the rotating shaft are arranged on the mooring rod and cooperate with the mooring rod support frame; the shear shaft is located above the rotating shaft.

[0004] After the above patent is overloaded and the mooring post is released, it is necessary to manually restore the mooring post to the state before the mooring post is released, so as to facilitate the mooring of the next passing ship. Therefore, a new device needs to be designed. Utility Model Content
