Description

Technical Field

[0001] This invention relates to the field of ship simulation test equipment technology, and in particular to a test device for ship berthing. Background Technology

[0002] In modern maritime transportation systems, ship berthing is a core element ensuring safe docking and efficient cargo loading and unloading. The smoothness of ship berthing directly affects the overall operational efficiency of a port and is closely related to the safety of the ship itself and the terminal facilities. To improve the efficiency of ship berthing operations and reduce potential safety risks, it is necessary to conduct ship berthing simulation tests during the ship design phase to verify the feasibility and safety of the design scheme.

[0003] Existing ship berthing test technologies still face numerous insurmountable technical bottlenecks. One of the most prominent challenges is the limitation of existing ship and marine engineering test pools in terms of wave generation capabilities. Specifically, most test pools can only generate waves in a single direction or within a limited angle range, failing to meet the simulation requirements of multi-directional wave environments under complex sea conditions. Furthermore, specialized equipment with multi-directional wave generation capabilities is not only structurally complex but also extremely expensive to produce and maintain, which significantly restricts the conduct of related tests.

[0004] Therefore, there is an urgent need for a testing device for ship berthing to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a test device for ship berthing, which can realize multi-wave berthing tests and reduce the cost of ship berthing tests.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The present invention provides a test device for ship berthing, including a rotating support assembly. The bottom end of the rotating support assembly is fixedly disposed at the bottom of the marine engineering test pool, and the top end of the rotating support assembly is fixedly disposed with a dock model or slipway model for simulating the berthing target. The rotating support assembly is configured to drive the dock model or slipway model to rotate to adjust the angular position relative to the wave direction.

[0028] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0029] like Figures 1 to 2 As shown, this embodiment provides a test apparatus for ship berthing. The apparatus includes a rotating support assembly 100, the bottom of which is fixedly mounted on the bottom of a marine engineering test tank. A dock model or slipway model simulating the berthing target is fixedly mounted on the top of the rotating support assembly 100. The rotating support assembly 100 is configured to drive the dock model or slipway model to rotate and adjust its angular position relative to the wave direction. This configuration allows the dock model or slipway model to be rotated to any specified angular position as needed, effectively adapting to the ship berthing test research requirements under different wave directions in a marine engineering test tank. It is easy to operate, has a wide range of applications, and does not rely on wave-generating equipment to produce multi-directional waves, thus significantly reducing the overall cost of ship berthing tests and improving test efficiency and flexibility.

[0030] It should be noted that in the physical model test of ship berthing, the ship model simulates the motion and forces of the active berthing party, while the dock model or slipway model simulates the passive berthing target. Together, they constitute a complete "ship-dock system", which allows researchers to systematically and repeatedly study in the experiment: safety under different berthing angles and speeds, the effectiveness of the hull fender system, the configuration and load of the mooring system, and berthing strategies under complex environmental loads (multi-directional wind, waves, and currents).

[0031] Specifically, this embodiment provides the following exemplary technical solution: the rotating support assembly 100 includes a rotating platform 1 and a slewing bearing 2. The slewing bearing 2 is cylindrical, and its bottom end is fixedly installed at the bottom of the marine engineering test pool. The rotating platform 1 is rotatably connected to the top end of the slewing bearing 2, and the dock model or slipway model is fixedly installed on the rotating platform 1. This configuration, employing a combined rotating fit structure, allows the rotating platform 1 to support the dock model or slipway model, while its center is supported by the slewing bearing 2. The rotating platform 1 can rotate around its central axis on the slewing bearing 2, further improving the reliability of the test process.

[0032] Optionally, to improve the smoothness of rotation of the rotating platform 1, the rotating support assembly 100 further includes several pulleys, which are arranged circumferentially below the edge of the rotating platform 1. Furthermore, to prevent unnecessary rotation of the rotating platform 1 during the test, after the rotating platform 1 has rotated to a specified angle position, several positioning blocks can be placed under the rotating platform 1 to increase its frictional resistance and fix it in place, thus ensuring the stability of the test process.

[0033] In this embodiment, in order to more accurately measure the stress on the hull fenders and the legs of the dock model or slipway model under the action of waves in different directions, and to reduce the influence on the flow field, the rotating platform 1 is provided with a number of first grooves and a number of second grooves. The first grooves are used to insert the legs of the dock model or slipway model, and the second grooves are used to set pressure sensors.

[0034] It should be noted that different numbers and specifications of first and second grooves can be set according to the wharf model or slipway model with different numbers of pile legs, and multiple wharf models or slipway models can be tested at the same time.

[0035] In other embodiments, force sensors, pressure sensors, displacement sensors, etc., can be installed on the dock model or slipway model to directly measure the impact force, fender reaction force, and minute deformation of the model when the ship berths.

[0036] Optionally, the test apparatus for ship berthing also includes a transition platform 3, in which the rotating platform 1 is embedded, and the upper surface of the rotating platform 1 and the upper surface of the transition platform 3 are at the same horizontal plane. In this configuration, the transition platform 3 is arranged around the rotating platform 1 and at the same height as the rotating platform 1 to ensure the uniformity of the flow field.

[0037] Optionally, the test apparatus for ship berthing further includes several support frames 4, which are arranged sequentially at intervals along the length of the transition platform 3. Each support frame 4 is fixedly mounted on the lower end face of the transition platform 3. The support frames 4 are supported between the bottom of the marine engineering test pool and the transition platform 3, so that the height of the transition platform 3 is the same as the height of the rotating platform 1. The length direction of the support frames 4 is perpendicular to the wave direction. Further, the support frames 4 are T-shaped.

[0038] In this embodiment, the test apparatus for ship berthing further includes a first oblique plate 5 and a second oblique plate 6. The first oblique plate 5 is fixedly connected to one end of the transition platform 3, and its length direction is perpendicular to the wave direction. The first oblique plate 5 has a first inclined surface that is inclined downwards. The second oblique plate 6 is fixedly connected to the other end of the transition platform 3, and its length direction is perpendicular to the wave direction. The second oblique plate 6 has a second inclined surface that is inclined downwards. This configuration allows the first oblique plate 5 and the second oblique plate 6 at both ends to smoothly connect the marine engineering test pool and the rotating platform 1, thereby avoiding excessive influence on the flow field and ensuring the accuracy of the test.

[0039] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
