Description

Technical Field

[0001] The utility model belongs to the field of port docks and relates to a floating dock, in particular to a floating dock lifting and adjusting structure in a stable water surface environment with a large water level difference. Background Art

[0002] Floating docks are highly adaptable to large water level differences, primarily due to their dock surface, which is not fixed like gravity-type or high-pile structures, but can instead rise and fall with water level fluctuations. Most passenger terminals in my country are pontoon docks, such as the Wuhan Zhonghua Road Passenger Terminal along the Yangtze River, the Wuhan Ferry Yellow Crane Tower Terminal, the Chongqing Chaotianmen Terminal, the Chongqing Cuntan Cruise Terminal, and the Taizhou Maritime Passenger Transport Center Terminal on the Jiaojiang River. Some specialized tourist terminals, located on inland rivers and lakes where water level fluctuations are minimal and hydrological conditions are relatively good, have simpler structures, often consisting of pontoon or float structures, such as the Qianfengyang Station and Nanyang Village Station, which accommodate cruise ships on the Changxing Beautiful Waterway.

[0003] A floating structure refers to a floating structure used for mooring cruise ships and for boarding and disembarking passengers. It mainly includes pontoons, anchors, and connecting bridges. A pontoon consists of a pontoon, a pontoon frame, and a pavement. In the Jiangsu and Zhejiang regions, where water networks are dense and water transportation is highly developed, floating structures have particularly demonstrated their uniqueness and adaptability. However, these regions also face the problem of large differences in river water levels between flood and dry seasons. Although the difference between the design high and low water levels is fully considered during the design, extreme flooding and dry seasons still occur, exceeding the design high and low water levels, resulting in excessive stress on the guiding structure of the floating dock, affecting its service life. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the guiding structure of a floating dock is subjected to great stress when the actual water level is higher than the designed high water level or lower than the designed low water level under extreme hydrological conditions. The utility model provides a floating dock lifting and adjusting structure in a stable water surface environment with a large water level difference. The floating dock can be smoothly lifted, lowered, floated and guided within the designed water level range, and the stress on the guiding structure can be reduced under extreme water level conditions, thereby avoiding damage to the floating dock.

[0005] The utility model discloses a technical scheme that solves its technical problem is: a big water level difference smooth water surface environment under floating wharf lifting adjustment structure, including the floating box wharf, the one side of floating box wharf sets the locating pile, the one side liftable of floating box wharf is set on the locating pile, the floating box wharf includes the floating box frame, and the floating box frame is embedded with the floating box body, and the clearance of adjacent floating box body is provided with the gasbag that can charge and discharge, the locating pile is sleeved with the sliding frame, the floating box wharf is fixed on the sliding frame, the floating box wharf is connected through upper and lower two connecting points with the sliding frame, wherein lower connecting point adopts articulated axle connection, and upper connecting point adopts detachable pin shaft or bolt connection.

[0006] The device is especially suitable for the Jiangnan region with large water level difference, and the water level data of the region is used as the design basis of the design high water level and the design low water level. However, the Jiangnan region still has flood period higher than the design high water level and dry period lower than the design low water level or even lower than the warning water level. Under the special hydrological conditions of the above flood period and dry period, the floating wharf of the present scheme does not have the use condition, and at this time, the use of the floating wharf is not considered, and the protection of the floating wharf itself is mainly considered.

[0007] During normal use, the floating box serves as the main source of buoyancy of the floating wharf, and the gasbag serves as the supplementary source of buoyancy, which together provide the buoyancy of the floating wharf, so that the floating wharf can maintain sufficient buoyancy under full load condition. During the flood period, the actual water level is higher than the design high water level, and at this time, the floating limit structure limits the floating wharf from continuing to rise, and the floating wharf will be submerged in water, and the buoyancy acting on the floating wharf is greater than the self-weight of the wharf. The buoyancy will act on the sliding guide sliding frame, and at this time, the gasbag is deflated to reduce the buoyancy acting on the floating wharf, thereby reducing the force acting on the sliding frame. During the dry period, when the floating wharf is lowered to the warning water level, the upper connecting point of the floating wharf and the sliding frame is disconnected, and when the water level continues to drop, the outer end of the floating wharf swings downward around the lower connecting point. At this time, the gasbag maintains the inflated state, so that the outer end of the floating wharf floats on the water surface, reducing the influence of the self-weight on the sliding frame. When the water level rises again, the upper connecting point of the floating wharf and the sliding frame is fixed again.

[0008] As a preferred, the sliding frame is uniformly provided with a plurality of guide wheels around the locating pile, and the guide wheels are divided into upper and lower two layers and arranged at the top and bottom of the sliding frame, respectively.

[0009] As a preferred, the number of the guide wheels in the upper and lower two layers is consistent and aligned.

[0010] As a preferred, a chain is arranged between the upper part of the sliding frame and the upper part of the floating wharf. The chain can provide traction protection when the upper connecting point of the floating wharf and the sliding frame is disconnected, and provide a pulling stress point during the re-fixing process, facilitating the alignment of the upper connecting point.

[0011] As preferred, the middle part of the positioning pile is a limiting section, the upper part and the lower part of the positioning pile are common sections, the outer diameter of the positioning pile of the limiting section is smaller than that of the common section, and a limiting step is formed at the joint of the limiting section and the common section.

[0012] As preferred, the highest point of the limiting section is flush with the designed high water level, and the lowest point of the limiting section is the warning water level which is lower than the designed low water level.

[0013] As preferred, the floating box body adopts high-density polyethylene floating box.

[0014] As preferred, the upper surface of the floating box frame is paved with a wharf surface layer.

[0015] The utility model is suitable for the Jiangnan area with large water level difference, ensures the smooth lifting of the floating box wharf under normal water level, and protects the lifting guide structure of the floating box wharf under extreme hydrological conditions.

[0022] The utility model will be further described below in combination with the drawings.

[0023] Embodiment: a floating wharf lifting adjusting structure under large water level difference and stable water surface environment, like Figure 1 、 4The structure is shown. The structure includes a pontoon wharf, a positioning pile 1 is arranged on one side of the pontoon wharf, and the one side of the pontoon wharf is sleeved on the positioning pile in a liftable manner. The pontoon wharf includes a pontoon frame 5, and a wharf surface layer 7 is arranged on the upper surface of the pontoon frame. A pontoon body 6 is embedded in the pontoon frame, and a gas bag 8 that can be inflated and deflated is arranged in the gap between adjacent pontoon bodies.

[0024] As shown in the figure, Figures 1-3 The positioning pile 1 has a limiting section 2 in the middle, and the upper part and the lower part of the positioning pile are ordinary sections. The outer diameter of the limiting section 2 of the positioning pile 1 is smaller than the outer diameter of the ordinary section of the positioning pile, and a limiting step is formed at the junction of the limiting section and the ordinary section. The highest point of the limiting section 2 is flush with the designed high water level, and the lowest point of the limiting section is the warning water level, which is lower than the designed low water level. A sliding frame 3 is sleeved on the limiting section 2 of the positioning pile 1, the pontoon wharf is fixed on the sliding frame 3, and the pontoon wharf is connected with the sliding frame 3 through upper and lower connecting points. The upper and lower connecting points are arranged at the pontoon frame end of the pontoon wharf, and the lower connecting point 10 is connected by a hinged shaft, and the upper connecting point 9 is connected by a detachable pin shaft or a bolt. A lock chain 11 is arranged between the upper part of the sliding frame 3 and the upper part of the pontoon wharf. A plurality of guide wheels 4 are uniformly arranged around the limiting section 2 of the positioning pile 1 of the sliding frame 3. The guide wheels 4 are arranged in two layers, i.e. the top layer and the bottom layer, and are arranged at the top and the bottom of the sliding frame 3 respectively. The number of the guide wheels 4 in the upper and lower layers is consistent and aligned.

[0025] As shown in the figure, Figure 1 When the wharf is in normal operation, the pontoon serves as the main source of buoyancy of the pontoon wharf, and the gas bag serves as the supplementary source of buoyancy, which together provide the buoyancy of the pontoon wharf, so that the pontoon wharf can maintain sufficient buoyancy under full load conditions. In the figure, the pontoon wharf and the sliding frame at the designed high water level are represented by solid lines, and the pontoon wharf and the sliding frame at the designed low water level and the warning water level are represented by dashed lines. Here, there is only one pontoon wharf, and the figure only shows that the pontoon wharf can be adjusted between different heights, and is not intended to represent multiple pontoon wharfs arranged above and below.

[0026] As shown in the figure, Figure 3 During the flood period, the actual water level is higher than the designed high water level. At this time, due to the limitation of the floating limiting structure, the floating wharf cannot continue to rise, and the pontoon wharf will be submerged in water, which is not suitable for open use. The buoyancy acting on the pontoon wharf is greater than the self-weight of the wharf, and the buoyancy will act on the sliding guide sliding frame. At this time, the gas bag is deflated to reduce the buoyancy acting on the pontoon wharf, thereby reducing the force acting on the sliding frame.

[0027] As shown in the figure, Figure 2As shown, in dry season, when the pontoon pier drops to the warning water level, the pontoon pier is not suitable for open use. At this time, the upper connecting point of the pontoon pier and the sliding frame is disconnected, and when the water level continues to drop, the outer end of the pontoon pier swings downward around the lower connecting point. At this time, the air bag remains inflated, so that the outer end of the pontoon pier floats on the water surface, reducing the effect of self-weight on the sliding frame. When the water level rises again, the upper connecting point of the pontoon pier and the sliding frame is fixed again.
