[0027] The present invention will be further described in detail below through specific embodiments. The following embodiments are only descriptive and not limiting, and should not be used to limit the protection scope of the present invention.

[0028] like Figure 1-3The illustrated marine exploration equipment deployment device includes: a swing arm assembly 13, a telescopic arm assembly 11, and a marine exploration equipment docking assembly 12, as well as a rotating base assembly 10 supporting the swing arm assembly 13. The swing arm assembly 13 employs a four-bar linkage structure to provide swing for the telescopic arm assembly 11. A telescopic cylinder is mounted on the upper part of the telescopic arm assembly 11 for its telescopic movement. A pulley system is mounted on the lower part for changing the direction of the composite cable. The marine exploration equipment docking assembly 12 is connected to the pulley bracket in front of the telescopic arm assembly 13 via two upper lifting lugs and a shaft, and a spring damping pair consisting of six sets of compression springs and guide rods is used in the middle.

[0029] like Figure 4-5 As shown, the slewing base assembly 10 includes: a base 1, a hydraulic pump 2, a bell-shaped housing 3, a motor 4, a hydraulic motor 5, a reducer 6, a pinion 7, a slewing bearing 8, and a slewing base 9.

[0030] The base 1 is used to install the hydraulic pump 2 and the motor 4 and to store hydraulic oil; the hydraulic pump 2 is mounted on the base 1 and connected to the hydraulic motor 5 through a pipe; the bell-shaped cover 3 is installed between the hydraulic pump 2 and the motor 4; the motor 4 is mounted on the base 1 and connected to the hydraulic pump 2 through a coupling; the hydraulic motor 5 is connected to the hydraulic pump 2 through a pipe and connected to the pinion 7 through a reducer 6; the reducer 6 is installed between the hydraulic motor 5 and the pinion 7; the pinion 7 meshes with the internal gear ring of the slewing bearing 8; the internal gear ring of the slewing bearing 8 meshes with the pinion 7, and the outer ring is mounted on the fixed base 1; the slewing base 9 is mounted on the inner ring of the slewing bearing 8, and the slewing bearing 8 enables rotation.

[0031] The hydraulic motor 5 receives the hydraulic power generated by the hydraulic pump 2 and converts it into mechanical energy. After being adjusted by the reducer 6, it drives the pinion 7 to rotate. The pinion 7 meshes with the internal gear ring of the slewing bearing 8, ultimately driving the slewing base 9 to achieve smooth 360° rotation.

[0032] This device is compatible with various marine exploration equipment (such as CTDs, ROV14 underwater robots, underwater cameras, etc.). It can be used for marine scientific research to obtain the vertical distribution of seawater physicochemical parameters. It can also be used for environmental monitoring to track pollutant diffusion or temperature anomalies. Furthermore, it can be used for resource exploration to assist in seabed topographic mapping and biological surveys.

[0033] The method of using this device is as follows:

[0034] Deployment Phase: After the cable passes through the pulley system, the equipment to be deployed is installed at the end of the marine exploration equipment docking assembly. Simultaneously, the winch releases the cable as the telescopic boom swings, and the main boom swings from inside the ship's side to outside, lowering the equipment into the water at a controlled speed. The marine exploration equipment is then lowered to the target depth for measurement using a pre-programmed procedure or manual operation.

[0035] Recovery Phase: The cable is wound up at a constant speed. Once the equipment reaches the appropriate recovery area, the telescopic cylinder is used to adjust the main boom's position for recovering the marine exploration equipment, preventing collisions caused by ship swaying. Then, the telescopic boom is fully retracted, and the luffing cylinder is used to swing the main boom from outside the ship's side to inside, placing the equipment on the main deck at an appropriate speed.

[0036] The docking assembly for marine exploration equipment at the front end of the main arm can mitigate the impact when the marine exploration equipment comes into contact with the deployment and retrieval system.

[0037] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the utility model, and these all fall within the protection scope of the present utility model.
