Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of waterway engineering, in particular to a multi-dock large water level difference ship sewage receiving and conveying system. BACKGROUND

[0002] Since 2000, China has successively issued a number of regulations to prevent and control ship pollution, promoting the prevention and control of ship pollution in inland rivers. In 2021, the "Yangtze River Protection Law" was implemented, providing legal guidance for the prevention and control of ship pollution in the Yangtze River. In 2020, the Chongqing Maritime Bureau proposed the concept of "zero discharge", that is, on-board storage and on-shore disposal to achieve no pollution on shore. In the same year, Chongqing revised the "Water Pollution Prevention Ordinance" and included on-shore centralized disposal of sewage. In 2022, the Yangtze River Maritime Bureau promoted "zero discharge" in Anhui and above. The "Guidelines for the Design of On-shore Sewage Receiving Facilities in Inland River Ports" stipulates that the design of receiving facilities should match the conditions of the wharf. Ship sewage storage tanks are usually equipped, but the ship pump has low lift and can only be delivered to the wharf face. In wharfs with little change in water level, ship pumps or self-priming pumps can be used to deliver sewage to the wharf storage device, and then to the designated location by water pump. These measures and technical provisions provide specific implementation paths for the prevention and control of ship pollution.

[0003] The water level in the reservoir area changes greatly, and the submerged range can reach more than 30 meters. To adapt to the water level change in the reservoir area, the wharf structure usually adopts a multi-layer platform pile foundation structure form, and the ship can be berthed at the corresponding berth of the platform at different water levels. The ship pump has a low lift for delivering ship sewage; the self-priming pump is limited by the suction distance and requires a high degree of vacuum for the suction pipe. When the suction pipe is long, self-priming operation is not convenient, and improper operation may result in failure to suck the sewage. When the submerged water level in the reservoir area is low, neither the ship pump nor the self-priming pump alone can meet the requirements of receiving and conveying ship sewage in layers and at different berths. At the same time, since the lower wharf face will be submerged, it is not suitable to set up power supply equipment.

[0004] In summary, the existing wharf structure cannot meet the requirements of receiving and conveying ship sewage in layers and at different berths. SUMMARY

[0005] The purpose of the present application is to overcome the above technical deficiencies and provide a multi-dock large water level difference ship sewage receiving and conveying system, which has a simple structure, high safety, can adapt to the berthing requirements of water level difference change and multi-dock, is convenient to operate and maintain, has low investment cost, and has good economic, environmental and social benefits.

[0030] The purpose of this application is to overcome the above-mentioned technical deficiencies and propose a sewage receiving and transportation system for multi-berth large water level difference wharves. The system has a simple structure, high safety, can adapt to changes in water level difference and the berthing requirements of multi-berth wharves, is easy to operate and maintain, has low investment costs, and has good economic, environmental and social benefits.

[0031] To achieve the above-mentioned technical objectives, the present application adopts the following technical solution:

[0032] This application provides a system for receiving and transporting sewage from ships at a multi-berth, large-water-difference wharf, such as... Figure 1 and Figure 2 As shown, Figure 1 This is a pipeline diagram of a ship sewage receiving and conveying system provided in an embodiment of this application for a multi-berth, large-water-difference wharf;

[0033] Figure 2 This is a schematic diagram of the plan position of a multi-berth, large-water-difference wharf ship sewage receiving and transport system provided in an embodiment of this application.

[0034] A multi-berth, large-water-difference wharf ship sewage receiving and transport system includes multiple berthing platforms 1 and a ship sewage receiving barge 3.

[0035] A multi-level berthing platform 1, with multiple berthing platforms 1 arranged at intervals, each level of the berthing platform 1 including multiple ship berths 2, each ship berth 2 being equipped with a first connecting pipe 21 and a second connecting pipe 22; and

[0036] The ship sewage receiving barge 3 includes a first temporary storage tank 33, a second temporary storage tank 34, and two built-in lift pumps. The first temporary storage tank 33 is connected to the first water inlet pipe 31, the second temporary storage tank 34 is connected to the second water inlet pipe 32, and the two built-in lift pumps are respectively connected to the first temporary storage tank 33 and the second temporary storage tank 34.

[0037] This embodiment of the application, by setting up a first main receiving pipe 23 and a second main receiving pipe 24 layer by layer on the berthing platform 1, allows ships to connect to the first main receiving pipe 23 and the second main receiving pipe 24 to adapt to changes in water level. Simultaneously, a ship sewage receiving pontoon 3, adaptable to changes in water level, is also provided. This enables a multi-berth, large-water-difference wharf to receive and transfer ship sewage through the corresponding berth pipelines on the wharf berthing platform 1 at different water levels and berths, meeting the requirements for stratified and berth-specific reception and transportation of ship oily wastewater and domestic sewage in special wharf configurations; it also fully utilizes the pump head and solves the problem of… This invention addresses the problem of insufficient pump head or self-priming pump suction head under large water level differences, while also solving the problem of limited selection of sewage lift pumps at docks. The suction head of self-priming pumps is no longer a limiting factor, and operation is convenient. It simplifies the operation for dock workers, enabling multiple berths to share a single sewage lift pump without dock workers moving the ship's sewage receiving facilities or sewage lift pumps. It is simple to operate, requires low daily maintenance, has low investment costs, and reduces the operating costs of ship transshipment when the floodwater level is low. It has good economic, environmental, and social benefits.

[0038] In some embodiments of this application, each of the mooring platforms 1 further includes a first trunk receiving pipe 23 and a second trunk receiving pipe 24. A plurality of first connecting pipes 21 arranged on the same layer are all connected to the first trunk receiving pipe 23, and a plurality of second connecting pipes 22 arranged on the same layer are all connected to the second trunk receiving pipe 24.

[0039] In this embodiment, a networked sewage receiving system is formed. When a ship is docked at a berth, the ship's sewage is introduced into the corresponding first main receiving pipe 23 or second main receiving pipe 24 through the first connecting pipe 21 or the second connecting pipe 22. The main receiving pipes centrally transport sewage collected from multiple berths on the same deck to the first temporary storage tank 33 or the second temporary storage tank 34 on the ship's sewage receiving pontoon 3. The temporary storage tanks temporarily store sewage, and built-in lift pumps extract the sewage from the temporary storage tanks and lift it to the sewage treatment facilities on the dock or transport it to a designated treatment location by other means.

[0040] The centralized management and transportation of sewage via the main receiving pipe improves system efficiency and reliability. It reduces direct connections between each berth and the sewage receiving barge, simplifying system complexity and facilitating operation and maintenance. The system design is adaptable to large water level variations, ensuring effective operation under different water level conditions.

[0041] In some embodiments of this application, the ship sewage receiving barge 3 further includes a first inlet pipe 31 and a second inlet pipe 32. The first inlet pipe 31 is connected to one end of the first main receiving pipe 23 and the first temporary storage cabinet 33, respectively. The second inlet pipe 32 is connected to one end of the second main receiving pipe 24 and the second temporary storage cabinet 34, respectively.

[0042] In this embodiment, the inlet pipe is directly connected to the main receiving pipe and the temporary storage cabinet, simplifying the sewage flow path and improving the conveying efficiency. The inlet pipe adopts a flexible hose design, which has good compatibility and can adapt to the sewage discharge requirements of different water levels and different ship types, ensuring stable system operation.

[0043] In some embodiments of this application, the first connecting pipe 21, the second connecting pipe 22, the first water inlet pipe 31 and the second water inlet pipe 32 include flexible hoses, and the first trunk receiving pipe 23 and the second trunk receiving pipe 24 include rigid pipes.

[0044] In this embodiment, after the ship docks at its berth, the main receiving pipe (rigid pipe) centrally transports sewage from multiple berths to the ship's sewage receiving pontoon 3. The main receiving pipe uses rigid pipe, providing a stable transport channel, reducing pressure loss, and improving transport efficiency. Rigid pipe has high structural strength, can withstand large pressures and flow rates, and is suitable for long-term use.

[0045] Hose hoses (first connecting pipe 21 and second connecting pipe 22) are used to connect the ship's sewage outlet to the main receiving pipe of the berthing platform 1. Sewage is transported to the main receiving pipe through the hoses, which have good flexibility and bendability to facilitate docking with the ship's sewage outlet.

[0046] In some embodiments of this application, the first trunk receiving pipe 23 and the second trunk receiving pipe 24 extend horizontally along the longitudinal direction of the wharf.

[0047] In this embodiment, the first trunk receiving pipe 23 and the second trunk receiving pipe 24 are arranged along the longitudinal horizontal direction of the berthing platform 1, that is, along the length of the berthing platform 1, parallel to the shoreline. Multiple first connecting pipes 21 and second connecting pipes 22 on each berthing platform 1 are respectively connected to the horizontally extending first trunk receiving pipe 23 and second trunk receiving pipe 24, thereby collecting the ship sewage from each berth into the trunk receiving pipe. Sewage flows from each berth into the trunk receiving pipe through the first connecting pipes 21 and second connecting pipes 22, and collects in the horizontal direction.

[0048] In some embodiments of this application, two lift mains 4 and two transfer mains 5 are also included. The two lift mains 4 are respectively connected to the first temporary storage cabinet 33 and the second temporary storage cabinet 34. Each lift main 4 includes multiple water inlets 41, which are arranged layer by layer. The transfer mains 5 are connected to the lift mains 4.

[0049] In this embodiment, the first temporary storage tank 33 and the second temporary storage tank 34 in the ship sewage receiving barge 3 collect sewage. The built-in lift pump draws the sewage from the temporary storage tanks and lifts it to the lift main pipe 4. After the sewage is lifted to the corresponding height through the lift main pipe 4, it is then transported to a sewage treatment facility or other treatment location on shore through the transfer main pipe 5.

[0050] The design of the booster trunk line 4 and the transfer trunk line 5 provides an efficient sewage transport channel, ensuring that sewage can be transported to the shore quickly and stably.

[0051] The system's design helps reduce pollution to the aquatic environment and meets environmental protection requirements.

[0052] In some embodiments of this application, the water inlets 41 in two adjacent lifting main pipes 4 are arranged layer by layer and correspond one to one, and the two corresponding water inlets 41 are arranged on the same layer and are respectively connected to the first temporary storage cabinet 33 and the second temporary storage cabinet 34.

[0053] In this embodiment, the inlets 41 of two adjacent riser pipes 4 are located on the same floor, forming a corresponding pair. This avoids cross-contamination between domestic sewage and oily wastewater during the transfer process.

[0054] In some embodiments of this application, the ship sewage receiving barge 3 further includes a first outlet pipe 35 and a second outlet pipe 36. The two inlets 41 arranged on the same floor are respectively connected to the first temporary storage cabinet 33 through the first outlet pipe 35 and to the second temporary storage cabinet 34 through the second outlet pipe 36.

[0055] In this embodiment, the layered inlets 41 enable the stratified collection of sewage from different berths, adapting to ship sewage discharge under different water level conditions.

[0056] Specifically, depending on the water level, the sewage receiving pontoon 3 is located at different heights. The pontoon is connected to two water inlets 41 on the same level as the pontoon through the first water outlet pipe 35 and the second water outlet pipe 36.

[0057] In some embodiments of this application, the first water outlet pipe 35 and the second water outlet pipe 36 include flexible hoses.

[0058] In this embodiment, these hoses have good flexibility and bendability, making it easy to connect with the sewage outlet of the barge and the inlet 41 of the lift pipe 4.

[0059] In some embodiments of this application, the lifting main pipe 4 extends vertically along the wharf pile foundation, that is, along the elevation direction of the berthing platform. The transfer main pipe 5 extends horizontally along the wharf approach bridge direction and along the width direction of the berthing platform.

[0060] In this embodiment, the oily wastewater and domestic sewage in the first temporary storage tank 33 and the second temporary storage tank 34 are pumped into two lifting main pipes 4 by built-in lifting pumps. The sewage rises in the lifting main pipes 4 and is discharged to a designated location on shore through the transfer main pipe 5 at or near the top of the lifting main pipes 4.

[0061] Optionally, the transfer trunk line 5 extends horizontally in the first direction, parallel to the wharf plane, to facilitate connection between the ship's sewage receiving barge 3 and onshore sewage treatment facilities or other treatment locations.

[0062] After extending horizontally for a certain distance, the transfer trunk line 5 extends vertically in a second direction, which is perpendicular to the first direction and parallel to the wharf plane. The transfer trunk line 5 repeats the above-mentioned horizontal and vertical extension process, forming a spiral path at the same elevation.

[0063] Through this circular path design, the transfer trunk line 5 forms a compact layout in space, reducing the footprint and making the system more compact and efficient.

[0064] The circulation path design of transfer trunk line 5 can greatly reduce the footprint, which is especially important in space-constrained dock environments.

[0065] The compact layout improves space utilization efficiency, enabling the system to efficiently complete the tasks of wastewater collection and transportation within a limited space.

[0066] Compared with the prior art, the beneficial technical effects of the technical solution provided in this application include:

[0067] This embodiment of the application, by setting up a first main receiving pipe 23 and a second main receiving pipe 24 layer by layer on the berthing platform 1, allows ships to connect to the first main receiving pipe 23 and the second main receiving pipe 24 to adapt to changes in water level. Simultaneously, a ship sewage receiving pontoon 3, adaptable to changes in water level, is also provided. This enables a multi-berth, large-water-difference wharf to receive and transfer ship sewage through the corresponding berth pipelines on the wharf berthing platform 1 at different water levels and berths, meeting the requirements for stratified and berth-specific reception and transportation of ship oily wastewater and domestic sewage in special wharf configurations; it also fully utilizes the pump head and solves the problem of… This invention addresses the problem of insufficient pump head or self-priming pump suction head under large water level differences, while also solving the problem of limited selection of sewage lift pumps at docks. The suction head of self-priming pumps is no longer a limiting factor, and operation is convenient. It simplifies the operation for dock workers, enabling multiple berths to share a single sewage lift pump without dock workers moving the ship's sewage receiving facilities or sewage lift pumps. It is simple to operate, requires low daily maintenance, has low investment costs, and reduces the operating costs of ship transshipment when the floodwater level is low. It has good economic, environmental, and social benefits.
