Description

Technical Field

[0001] The invention relates to the technical field of ship engineering, and in particular to a bracket for fixing force measurement of a ship model and a ship model force measurement device. Background Art

[0002] As a major water conservancy country, my country's inland waterway shipping is a strategic basic industry and a key component of the country's comprehensive transportation system and comprehensive utilization of water resources. It has the advantages of large transportation volume, long transportation distance, low energy consumption, low cost, small land occupation and light pollution. The construction of navigation buildings is an important means to achieve river channelization and connect different water systems. As the most important navigation hub building, the ship lock occupies a very important position in inland waterway shipping. Therefore, in the design and operation of the ship lock, it is of great significance to ensure the safe passage of ships. Relatively speaking, ships moored in the lock chamber are greatly affected by the filling and discharge of the lock chamber. Since the external loads on the ship are transmitted to the mooring facilities through the cable, the ship's mooring force can represent the ship's mooring conditions. The mooring force is generated by the water flow force, which includes the local force generated by the turbulence of the water flow, the velocity force generated by the longitudinal flow velocity, and the wave force generated by the surface waves in the lock chamber. Affected by factors such as the non-constant water flow in the lock chamber and the berthing position of the ship, the ship's mooring force is divided into transverse mooring force and longitudinal mooring force. If the mooring force exceeds the allowable value in the specification, it may cause safety accidents such as cable breakage and capsizing. Therefore, it is of practical significance to strengthen the systematic research on the mooring force of ships in the lock chamber. The safety of ships passing through the lock, especially the mooring safety of ships in the lock chamber during water transfer, has always been the most concerned issue in the design and research of the lock.

[0003] Ship mooring force detection is one of the important measures to ensure the safety of ships during mooring at the dock or pilot channel. The size of the mooring force directly affects whether the ship can be stably docked at the dock or pilot channel, especially under conditions of strong winds and waves or significant tidal changes. Therefore, the correct evaluation and monitoring of mooring force is of great significance for preventing accidents and ensuring the safety of personnel and property. Due to the complexity of lock hydraulics, the ship mooring force is usually measured through lock physical model research tests. Lock physical model research tests are an important test method for studying the navigation performance and hydrodynamic performance of ships. By scaling down the entire or part of the actual ship to make a ship model and conducting corresponding tests, it occupies a very important position in ship design and research.

[0004] The utility model patent with the patent number CN212567757U discloses a device for measuring the ship mooring force in the lock chamber during the filling and discharge process of a laboratory ship lock, including a measuring component, a lock component and a cable tension collection system, wherein the measuring component is fixed on the upper surface of the test ship, and the measuring component includes a fixed baffle, a tension and pressure sensor, a force transmission frame, a guard string, a slider and a slideway bracket, wherein the fixed baffle is fixed on the upper surface of the test ship, the tension and pressure sensor is installed on the right side of the fixed baffle, the force transmission frame is fixed on the right side of the tension and pressure sensor, and the guard string is fixed inside the force transmission frame. However, the truss described in the patent is horizontally fixed above the lock chamber and fixed to the lock wall, and the upper end of the column is fixed on the truss, and the column passes through the hull of the test ship (5). Since the truss and the column are relatively fixed, the measurement position for the ship model is also relatively fixed, and the position of the ship model in the lock cannot be changed, and thus the force conditions of the ship model at different positions in the lock chamber cannot be measured, that is, it cannot meet more test requirements, and there are certain limitations.
