Description

Technical Field

[0001] This utility model belongs to the field of port engineering technology, and in particular relates to a dynamic opening and closing environmental protection device for a wharf wave-breaking hole. Background Technology

[0002] Existing wave breakers at wharves mostly employ a perforated structure, primarily functioning to release pressure on the wharf surface and prevent wave impact from damaging the foundation structure. However, the existing structures of wave breakers at bulk cargo wharves have revealed the following problems: First, materials and wastewater from washing are directly discharged into the sea through the wave breakers, violating environmental regulations; second, while temporary sealing with fillers can solve the pollution problem in the short term, it hinders the pressure relief function of the wave breakers and increases structural safety hazards. Therefore, there is an urgent need for an innovative device that can meet environmental protection requirements while retaining the function of the wave breakers. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a dynamic opening and closing environmental protection device for a wharf wave-breaking hole. Through an adaptive opening and closing structure, it achieves the dual goals of environmental compliance and wharf structural safety, and solves the problem of synergistic optimization of pollutant discharge into the sea and the pressure relief function of the wave-breaking hole in bulk cargo terminal operations.

[0004] The purpose of this utility model is achieved through the following technical solution: a dynamic opening and closing environmental protection device for a wharf wave-breaking hole, comprising:

[0005] The pressure relief base is a platform with the same cross-sectional shape as the wave-breaking hole. It has a pressure relief hole and a through groove in the center to accommodate a central pin. The central pin passes through the through groove and passes through the pressure relief base. A closing cover plate and a limiting base plate are installed at both ends.

[0006] The sealing cover is installed on one side of the large-area bottom surface of the pressure relief base, and has the same shape as the large-area bottom surface of the pressure relief base. It can fit snugly against the inner wall of the pressure relief base through the sealing groove and sealing ring.

[0007] The limiting base plate is installed on one side of the small-area bottom surface of the pressure relief base.

[0008] Furthermore, the cross-section of the pressure relief base includes a circle or a square.

[0009] Furthermore, the sealing ring is made of a seawater corrosion resistant material, and the depth of the sealing groove is one-third of the thickness of the sealing cover plate.

[0010] Furthermore, the inclination of the pressure relief base is consistent with the inclination of the inner wall of the wave-breaking hole to be installed, and it is connected to the dock structure by welding.

[0011] Furthermore, the area of ​​the limiting base plate is larger than that of the through groove but smaller than that of the bottom surface of the pressure relief base on the mounting side.

[0012] Furthermore, the length of the center pin is greater than that of the through groove, allowing it to move freely along the direction of the through groove.

[0013] Furthermore, when the cross-section of the pressure relief base is not circular, the center pin is provided with a sliding limiting structure, and the through groove is provided with a positioning groove corresponding to the sliding limiting structure to limit the rotation of the center pin.

[0014] The outstanding and beneficial technical effects of this utility model compared to the prior art are:

[0015] This utility model is vertically fixed inside the wave-breaking hole at the wharf. The wave-breaking hole is an inverted frustum-shaped opening on the wharf surface, typically used to relieve pressure on the wharf surface during severe weather, preventing excessive stress. In calm conditions, the weight of the sealing plate and the pre-tightening force of the sealing ring achieve a seal, preventing pollutants from leaking out. During strong winds and waves, the impact force of the waves and the wind lift the sealing plate to release pressure. This device resolves the contradiction between environmental protection and functionality in traditional wave-breaking holes, featuring a simple structure that combines environmental friendliness and safety.

[0036] Combination Figure 8 In (a)-(c), the pressure relief base 1 is trapezoidal, the outer upper diagonal diameter of the pressure relief base 1 is consistent with the outer upper diagonal diameter of the wave-breaking hole, and the inclination of the cone is consistent with the inclination of the inner wall of the wave-breaking hole, so as to ensure that it can fit against the inner wall of the wave-breaking hole.

[0039]

[0040]

[0041]

[0042] in, The recommended seawater density (according to the "Port and Waterway Hydrology Code" (JTS 145-2015) is usually taken as...) ); acceleration due to gravity ; To obtain the water depth at high tide (the vertical distance from the bottom of the pier to the still water surface), consult the latest nautical charts issued by the local maritime authorities, obtain the water depth data below the reference level, and then overlay it with the real-time tide level (tide forecast required). To determine the wave height, the significant wave height and period are inverted using wind field data (wind speed, wind area, wind time) through empirical formulas (such as the SMB method): ,in For wind speed, This refers to the length of the wind zone, or refer to the regional wave rose diagram or extreme wave height statistics table in the "Hydrological Specifications for Ports and Waterways" (JTS 145-2015); wave number ( (Where the wavelength is calculated from the dispersion relation); This represents the total water depth from the seabed to the still water surface (used for wave theory calculations).

[0043] The wind pressure it withstands can be approximated by the following formula:

[0044]

[0045] The dynamic opening and closing environmental protection device has the following load-bearing capacity:

[0046]
