A wave-prevention and wave-suppression device for the entrance of the harbor basin

Abstract

The invention discloses a wave prevention and elimination device used for a harbor basin entrance. The wave prevention and elimination device comprises a sealed rectangular buoyant box. A plurality of vertical guide piles are connected to the rectangular buoyant box in a penetrating mode. One end of each vertical guide pile is vertically piled into the bottom of a harbor basin, and the other end of the vertical guide pile stretches out of the rectangular buoyant box. The exterior of the portion, stretching out of the rectangular buoyant box, of each vertical guide pile is wound by a spiral conducting wire tube. The conducting wire tubes are made of elastic materials. A plurality of box bodies are arranged in the rectangular buoyant box. A inflating and deflating valve is arranged at the upper end of each box body. The inflating and deflating valves are connected to a inflating and deflating pipeline. The inflating and deflating pipeline is connected to an air pump. The air pump is connected outwards to the conducting wire tubes. A water filling and draining valve is connected to the lower end of each box body. The water filling and draining valves are connected to a water filling and draining pipeline. The water filling and draining pipeline is connected outwards to the exterior of the rectangular buoyant box. The wave prevention and elimination device has a wave prevention function at the harbor basin entrance, ships can get in and out of the harbor basin conveniently, the design wave height of relative buildings in the harbor basin is effectively decreased, and ship mooring stability is achieved.

Description

Technical field [0001] The invention relates to a wave-preventing and wave-eliminating device used for the entrance door of a harbor basin, and belongs to the technical field of port hydraulic structures. Background technique [0002] The function of the breakwater is to provide good berthing conditions for the port area, block the impact of waves, maintain the stability of the water surface in the port, and facilitate ship loading and unloading operations. An opening is formed between the heads of the breakwater, which serves as a passage for ships to come and go. However, although the port site is selected to avoid the strong wave direction, the diffraction phenomenon generated during wave propagation cannot be ignored. Therefore, wave propagation phenomenon still exists in the harbor basin under normal working conditions. Poor wave conditions in the harbor basin will require higher design wave heights for hydraulic structures in the harbor basin, which can easily lead to prob...

AI Technical Summary

Problems solved by technology

However, although the location of the port is designed to avoid the direction of strong waves, the diffraction phenomenon generated during wave propagation cannot be ignored, so there are still wave propagation phenomena in the harbor basin under normal working conditions

Unfavorable wave conditions in the harbor basin will require a higher design wave height for the hydraulic structures inside the harbor basin, which will easily lead to problems such as increased difficulty in engineering construction, high engineering costs, and difficult maintenance and operation of buildings and auxiliary facilities in the later period. Unfavorable wave conditions can also easily have adverse effects on ships berthing

[0003] In related fields related to port hydraulic structures, little attention has been paid to the structural type of wave-proof and wave-dissipating components at the port gate. The design has low hydrophilicity and requires large-scale equipment support to realize it, so it is difficult to apply it to the engineering site
