DETAILED DESCRIPTION

[0022] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0024] Moon pool gates are devices specially designed to control the deployment and recovery of sonar or other equipment, usually installed on the bottom of automated ships. Their design takes into account the complexity of the marine environment and the needs of automated ship operations, ensuring that the sonar can be stably lowered underwater and quickly and accurately recovered when needed. The structure of the moon pool gate usually includes a release system, a recovery system and a control system. Through the coordinated work of these systems, automated ships can effectively complete sonar detection tasks.

[0025] In actual operation, the automated ship slowly lowers the sonar underwater through the moon pool door to perform sonar detection or measurement. The design of the moon pool door makes the sonar lowering process more stable, avoiding unexpected situations caused by waves or currents. At the same time, the moon pool door can also ensure that the sonar maintains a good posture and position during underwater work to ensure the accuracy and reliability of the measurement data.

[0026] In response to the demand for underwater equipment deployment and recovery functions, the existing manual mechanical control and electrical semi-automatic control sliding and pulling moon pool door solutions are implemented to achieve unmanned and autonomous deployment and recovery of acoustic instruments, optical instruments, UUVs, ROVs and other platforms.

[0027] Regarding the above-mentioned related technologies, the inventor believes that the industry has carried out some automation work in the automatic deployment and recovery devices, but there are still major deficiencies and it is impossible to achieve fully autonomous deployment and recovery.

[0028] In order to achieve fully autonomous deployment and recovery, the present application provides an automatic push-pull moon pool door device that meets the needs of a hanging device.

A hoisting assembly 3 for driving the dipping sonar 2 to move up and down is arranged on the bottom plate 1, and the hoisting assembly 3 is used to hoist and drive the dipping sonar 2. A driving assembly is arranged on the bottom plate 1, and the driving assembly controls the movement and opening and closing of the hoisting assembly 3 and the sealed hatch 11.

[0031] Driving components for opening the sealed hatch 11 are arranged on both sides of the sealed hatch 11. In some embodiments, the driving components may be hydraulic driving components or pneumatic components. The driving components are arranged horizontally, and the driving components drive the sealed hatch 11 to move horizontally, thereby driving the interior of the automated ship to be relatively connected to the outside through the horizontal movement of the sealed hatch 11. When the sealed hatch 11 is opened, the dipping sonar 2 located inside the automated ship can be protruded from the outside of the automated ship through the position where the sealed hatch 11 is opened, and when the dipping sonar 2 is retracted from the outside of the automated ship, the sealed hatch 11 is closed through the driving components.

[0032] A slide rail 4 is horizontally arranged on the bottom plate 1, and the slide rail 4 is fixedly connected to the bottom plate 1, and the sealed cabin door 11 is located on the slide rail 4 and is relatively slidably connected.
