Description

Technical Field

[0001] The invention relates to the field of marine equipment, and in particular to a marine adaptive hydraulic stabilizing device. Background Art

[0002] When a ship docks or transfers materials or personnel between two ships, the hull moves violently due to the swaying, swaying, heaving, rolling, pitching, and bowing of the waves. In response to the needs of loading and unloading cargo and getting people on and off ships, people have built port terminals and related supporting equipment such as port machinery. When the hull is large and the wind and waves in the port are small, the operation is relatively stable and safe. However, when small and medium-sized ships operate in bad weather or temporary simple docks, the hull moves greatly relative to the dock ground, posing a great safety hazard.

[0003] At present, no effective solution specifically for this problem has been found. Some technologies use anti-roll equipment and shock absorbers, but the response is slow, the equipment requires a large area, and is mostly used in large ships. For example, the patent name: A ship-borne stabilizing platform with load-bearing capacity, patent number: CN112303446A; some stabilizing devices are limited to ensuring that a certain ship-borne equipment is not affected by the movement of the hull when it is running, and are auxiliary devices for the ship-borne equipment, such as "Design and Implementation of a Ship-borne Laser Rangefinder Stabilizing Platform", but do not involve how to safely transfer goods and personnel between two relatively moving objects. Summary of the invention

[0004] In view of the deficiencies of the prior art, the present invention provides a ship-based adaptive hydraulic stabilizer, which can ensure the safety and comfort when loading and unloading cargo and getting on and off personnel.

[0005] In order to achieve the above technical objectives, the present invention is implemented through the following technical solutions:

[0006] A ship-use adaptive hydraulic stabilization device includes a magnetic suspension system, a control drive system, four hydraulic cylinders, a stabilization platform, three sensors, and a target. The magnetic suspension system is installed on the deck of the ship, the control drive system is installed above the magnetic suspension system, one end of the four hydraulic cylinders is connected to the control drive system, and the other end is connected to the stabilization platform. The three sensors are installed on the stabilization platform, and their distribution positions are not in a straight line. The target is installed on the ground of the dock.

[0007] Furthermore, the target is portable and can be deployed and raised.

[0008] Furthermore, the magnetic levitation system can suspend the main equipment in the air and break contact with the hull. Three sensors are installed on the stabilization platform, which can continuously identify and capture the target and measure the relative distance and angle to the target. The control drive system can calculate the vertical relative distance between the three sensors and the target based on the distance and angle data sent by the sensor, and drive the hydraulic cylinder to continuously adjust the position and angle of the stabilization platform so that the three sensors and the target can reach relative stillness in the vertical direction.

[0009] Furthermore, the target is installed on the docked ship, and the main equipment is installed on the dock ground, or the target is installed on ship A, and the main equipment is installed on ship B, and similar scenarios.

[0010] The present invention proposes a ship-based adaptive hydraulic stabilization device that can convert the uncontrolled violent and large relative motion between two objects into a controllable slow acceleration and deceleration process to achieve a relatively stable and safe effect. The present invention is applied in the scene of ship loading and unloading, and can minimize the impact of ship movement on operations. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The technical solution of the present invention is further described below according to specific embodiments. The protection scope of the present invention is not limited to the following embodiments, which are listed for illustrative purposes and do not limit the present invention in any way.

[0014] Figure 1 This is a schematic structural diagram of an embodiment of the present invention, which is a ship-based adaptive hydraulic stabilization device, including a magnetic suspension system 1, a control drive system 2, four hydraulic cylinders 3, a stabilization platform 4, three sensors 5, and a target 6.

[0015] The magnetic suspension system 1 can suspend the main equipment in the air, solving the influence of sway and pitch on the stabilizing platform. The three sensors 5 installed on the stabilizing platform 4 can continuously identify and capture the target 6, and send the distance and angle information to the control and driving system 2. The control and driving system 2 solves the three sets of distance and angle information to obtain the vertical distance of the three sensors 5 relative to the target 6, and adjusts the actions of the four hydraulic cylinders 3 respectively, finally making the three sensors 5 and the target 6 almost relatively still in the vertical direction, solving the influence of the hull's sway, roll, pitch and bow on the stabilizing platform.

[0016] When the ship's adaptive hydraulic stabilization device is working, the target 6 is first removed from the ship and installed at a suitable position on the dock. The relative height of the target and the stabilization platform is adjusted to ensure that the sensor 5 can be effectively identified, and then the adaptive mode can be turned on.

[0017] According to the requirements of ship loading and unloading at the dock, the structure has two working conditions:

[0018] When cargo and personnel are boarding the ship from the dock, the ship's adaptive hydraulic stabilization device is activated. When the stabilization platform 4 is almost stationary relative to the dock ground, a ladder is set up between the dock and the stabilization platform 4, so that cargo and personnel can reach the stabilization platform safely and comfortably. Then, the ladder is disconnected from the stabilization platform 4, and the structure slowly locks the hydraulic cylinder, turns off the magnetic suspension function, makes the stabilization platform 4 stationary relative to the ship, and the cargo and personnel are transferred from the stabilization platform 4 to the ship deck, thus completing the loading process.

[0019] When the cargo and personnel are to disembark, they are first transferred to the stabilizing platform 4, and a ship-used adaptive hydraulic stabilizing device is started to slowly bring the stabilizing platform 4 to a position almost stationary relative to the dock ground. A ladder is set up between the dock and the stabilizing platform 4, and the cargo and personnel can then safely and comfortably reach the dock to complete the unloading.

[0020] The function of the present invention is to convert the violent and large relative motion between the ship and the dock ground into a controllable slow acceleration and deceleration process, so as to achieve a relatively stable and comfortable effect.

[0021] The above is an implementation example. In actual use, the target 6 and the sensor 5 of the present invention are flexibly arranged, and the following usage scenarios are common:

[0022] 1. Install the main equipment on the ship, and temporarily install the target 6 on the dock when docking;

[0023] 2. Install the main equipment at the dock. When the ship docks, temporarily install the target 6 on the ship;

[0024] 3. When transferring cargo between ships at sea, the main equipment is installed on Ship A and target 6 is installed on Ship B.

[0025] The embodiments described in the present invention are exemplary only, and various other substitutions, changes and improvements can be made within the scope of the present invention. Therefore, the present invention is not limited to the above embodiments, but only limited by the claims.
