Description

Technical Field

[0001] The invention relates to the technical field of water transport engineering, and in particular to a ship sewage receiving and conveying system at a multi-berth large water level difference terminal. Background Art

[0002] Since 2000, my country has successively issued a number of laws and regulations on the prevention and control of pollution from ships to promote the prevention and control of pollution from inland ships. In 2021, the Yangtze River Protection Law was implemented, providing legal guidance for the prevention and control of pollution from ships on the Yangtze River. In 2020, the Chongqing Maritime Safety Administration proposed the concept of "zero emission", that is, storage on board and disposal on shore to achieve the goal of not bringing pollutants ashore. In the same year, Chongqing revised the "Regulations on the Prevention and Control of Water Pollution" to include centralized disposal of sewage on shore. In 2022, the Yangtze River Maritime Safety Administration promoted "zero emission" in Anhui and above. The "Guidelines for the Design of Onshore Reception Facilities for Inland Ports of Ship Water Pollutants" stipulates that the design of reception facilities should match the conditions of the terminal. Ship sewage storage cabinets are usually equipped, but the ship pump has a low head and can only be transported to the dock surface. At docks where the water level does not change much, ship pumps or self-priming pumps can be used to transport sewage to the dock storage device, and then pumped to the designated location. These measures and technical regulations provide a specific implementation path for the prevention and control of ship pollution.

[0003] The water level in the reservoir area varies greatly each year, and the flooding range can reach more than 30 meters. In order to adapt to the water level changes in the reservoir area, the dock structure usually adopts a multi-layer platform pile foundation structure, so that ships can berth at the corresponding berths of the platform at the corresponding elevation at different water levels. The head of ship pumps for transporting ship sewage is relatively low; self-priming pumps are limited by the suction range and have high requirements for the vacuum level of the suction pipe. When the suction pipe is long, the self-priming operation is inconvenient, and improper operation may result in the situation where sewage cannot be sucked up. When the flooding water level in the reservoir area is low, the use of ship pumps or self-priming pumps alone cannot achieve the requirements of receiving and transporting ship sewage in layers and berths. At the same time, since the lower dock surface will be flooded, it is not suitable to set up power connection equipment.

[0004] In summary, the existing wharf structure cannot meet the requirements of receiving and transporting ship sewage in layers and berths. Summary of the invention

[0005] The purpose of this application is to overcome the above-mentioned technical deficiencies and propose a ship sewage receiving and conveying system for a multi-berth large water level difference terminal, which has a simple structure, high safety, can adapt to changes in water level differences and the berthing requirements of multi-berth terminals, is easy to operate and maintain, has a low investment cost, and has good economic, environmental and social benefits.

[0021] The purpose of this application is to overcome the above-mentioned technical deficiencies and propose a ship sewage receiving and conveying system for a multi-berth large water level difference terminal, which has a simple structure, high safety, can adapt to changes in water level differences and the berthing requirements of multi-berth terminals, is easy to operate and maintain, has a low investment cost, and has good economic, environmental and social benefits.

[0022] In order to achieve the above technical objectives, this application adopts the following technical solutions: The present application provides a system for receiving and conveying sewage from ships at a multi-berth large water level difference terminal, such as Figure 1 and Figure 2 As shown, Figure 1 This is a pipeline schematic diagram of a ship sewage receiving and conveying system for a multi-berth large water level difference terminal provided in an embodiment of the present application; Figure 2 It is a schematic diagram of the plan position of a ship sewage receiving and conveying system at a multi-berth large water level difference terminal provided in an embodiment of the present application.

[0023] A ship sewage receiving and conveying system for a multi-berth large water level difference wharf comprises a plurality of berthing platforms 1 and a ship sewage receiving pontoon 3: A multi-layer berthing platform 1, wherein the multi-layer berthing platforms 1 are arranged at intervals, each layer of the berthing platform 1 comprises a plurality of ship berths 2, and each of the ship berths 2 is provided with a first connecting pipe 21 and a second connecting pipe 22; and The ship sewage receiving pontoon 3 includes a first temporary storage cabinet 33, a second temporary storage cabinet 34 and two built-in lifting pumps. The first temporary storage cabinet 33 is connected to the first water inlet pipe 31, the second temporary storage cabinet 34 is connected to the second water inlet pipe 32, and the two built-in lifting pumps are respectively connected to the first temporary storage cabinet 33 and the second temporary storage cabinet 34.

[0024] The embodiment of the present application sets the first trunk receiving pipe 23 and the second trunk receiving pipe 24 on the berthing platform 1 layer by layer, so that the ship can adapt to the change of water level and connect the first trunk receiving pipe 23 and the second trunk receiving pipe 24. At the same time, a ship sewage receiving pontoon 3 that can adapt to the change of water level is set, so that the multi-berth large water level difference wharf can receive and transfer ship sewage through the corresponding berth pipeline of the wharf berthing platform 1 at different water levels and different berths, and meet the requirements of receiving and transporting oily sewage and domestic sewage of ships in layers and berths in special wharf forms; make full use of the ship pump head, solve the problem It solves the problem of insufficient ship pump head or self-priming pump suction under large water level difference, and also solves the problem of limited selection of dock sewage lifting pumps. The suction head of the self-priming pump is no longer a limiting factor, and the operation is easy; it simplifies the operation of dock staff, and the requirement of sharing a set of sewage lifting pumps for ships at multiple berths is achieved without the dock staff moving the ship sewage receiving facilities or sewage lifting pumps; it is simple to operate, with low daily maintenance requirements and low investment costs, and reduces the operating costs of ship water transit transportation when the flooding water level is low, with good economic, environmental and social benefits.

[0025] In some embodiments of the present application, each of the berthing platforms 1 also includes a first main receiving pipe 23 and a second main receiving pipe 24, and multiple first connecting pipes 21 arranged on the same layer are all connected to the first main receiving pipe 23, and multiple second connecting pipes 22 arranged on the same layer are all connected to the second main receiving pipe 24.

[0026] In this embodiment, a networked sewage receiving system is formed. When a ship is docked at a berth, the sewage of the ship is introduced into the corresponding first trunk receiving pipe 23 or second trunk receiving pipe 24 through the first connecting pipe 21 or the second connecting pipe 22. The trunk receiving pipe centrally transports the sewage collected from multiple berths on the same floor to the first temporary storage cabinet 33 or the second temporary storage cabinet 34 on the ship sewage receiving pontoon 3. The temporary storage cabinet temporarily stores sewage, and the built-in lifting pump extracts the sewage from the temporary storage cabinet and lifts it to the sewage treatment facility on the dock or transports it to the designated treatment site by other means.

[0027] Through the main receiving pipe, centralized management and transportation of sewage is achieved, which improves the efficiency and reliability of the system. The direct connection between each berth and the sewage receiving pontoon is reduced, which simplifies the complexity of the system and facilitates operation and maintenance. The system design can adapt to the changes of large water level differences and ensure effective operation under different water level conditions.

[0028] In some embodiments of the present application, the ship sewage receiving pontoon 3 also includes a first water inlet pipe 31 and a second water inlet pipe 32, the first water inlet pipe 31 is respectively connected to one end of the first main receiving pipe 23 and the first temporary storage cabinet 33, and the second water inlet pipe 32 is respectively connected to one end of the second main receiving pipe 24 and the second temporary storage cabinet 34.

[0029] In this embodiment, the water inlet pipe is directly connected to the main receiving pipe and the temporary storage cabinet, which simplifies the sewage flow path and improves the transportation efficiency. The water inlet pipe adopts a hose design with good compatibility, which can adapt to the sewage discharge requirements of different water levels and different types of ships, ensuring the stable operation of the system.

[0030] In some embodiments of the present 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 hoses, and the first trunk receiving pipe 23 and the second trunk receiving pipe 24 include hard pipes.

[0031] In this embodiment, after the ship docks at the berth, the main receiving pipe (hard pipe) centrally transports sewage from multiple berths to the ship sewage receiving pontoon 3. The main receiving pipe adopts a hard pipe, which provides a stable transportation channel, reduces pressure loss, and improves transportation efficiency. The hard pipe has a high structural strength, can withstand large pressure and flow, and is suitable for long-term use.

[0032] The hoses (the first connecting pipe 21 and the second connecting pipe 22) are used to connect the sewage outlet of the ship and the main receiving pipe of the berthing platform 1. The sewage is transported to the main receiving pipe through the hoses, which have good flexibility and bendability, and are convenient for docking with the sewage outlet of the ship.

[0033] In some embodiments of the present application, the first trunk receiving pipe 23 and the second trunk receiving pipe 24 extend horizontally along the longitudinal direction of the wharf.

[0034] 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, the length direction of the berthing platform 1 is parallel to the shoreline. The multiple first connecting pipes 21 and the second connecting pipes 22 on each berthing platform 1 are respectively connected with the horizontally extending first trunk receiving pipe 23 and the second trunk receiving pipe 24, so that the sewage of the ships on each berth is collected into the trunk receiving pipe. The sewage flows from each berth into the trunk receiving pipe through the first connecting pipe 21 and the second connecting pipe 22 and is collected in the horizontal direction.

[0035] In some embodiments of the present application, two lifting main pipes 4 and two transfer main pipes 5 are further included. The two lifting main pipes 4 are respectively connected to the first temporary storage cabinet 33 and the second temporary storage cabinet 34. Each of the lifting main pipes 4 includes a plurality of water inlets 41. The plurality of water inlets 41 are arranged layer by layer. The transfer main pipe 5 is connected to the lifting main pipe 4.

[0036] In this embodiment, the first temporary storage tank 33 and the second temporary storage tank 34 in the ship sewage receiving pontoon 3 collect sewage, and the built-in lifting pump extracts the sewage from the temporary storage tank and lifts it to the lifting main pipe 4. After the sewage is lifted to a corresponding height through the lifting main pipe 4, it is transported to the sewage treatment facility or other treatment location at a designated location on the shore through the transfer main pipe 5.

[0037] The design of the lifting main pipe 4 and the transfer main pipe 5 provides an efficient sewage transportation channel, ensuring that the sewage can be transported to the shore quickly and stably.

[0038] The design of the system helps to reduce pollution to the aquatic environment and meets environmental protection requirements.

[0039] In some embodiments of the present application, the water inlets 41 in two adjacent lifting mains 4 are arranged layer by layer and correspond one to one, and the corresponding two 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.

[0040] In this embodiment, the water inlets 41 of two adjacent lifting main pipes 4 are arranged at the same level, forming a pair of corresponding relationships, so as to avoid the domestic sewage and the oily sewage from crossing each other during the transfer process.

[0041] In some embodiments of the present application, the ship sewage receiving pontoon 3 also includes a first outlet pipe 35 and a second outlet pipe 36, and the two water inlets 41 arranged on the same floor are respectively connected to the first temporary storage cabinet 33 through the first outlet pipe 35 and connected to the second temporary storage cabinet 34 through the second outlet pipe 36.

[0042] In this embodiment, the water inlets 41 arranged layer by layer can realize the stratified collection of sewage from different berths and adapt to the discharge of ship sewage under different water level conditions.

[0043] Specifically, the height of the ship sewage receiving pontoon 3 is different according to different water levels, and the pontoon is connected to two water inlets 41 on the same level as the pontoon through a first outlet pipe 35 and a second outlet pipe 36 .

[0044] In some embodiments of the present application, the first water outlet pipe 35 and the second water outlet pipe 36 include hoses.

[0045] In this embodiment, these hoses have good flexibility and bendability, and are convenient for docking with the sewage outlet of the pontoon and the water inlet 41 of the lifting main pipe 4 .

[0046] In some embodiments of the present application, the lifting main pipe 4 extends vertically along the wharf pile foundation, that is, extends along the elevation direction of the berthing platform. The transfer main pipe 5 extends horizontally along the wharf approach bridge direction and extends along the width direction of the berthing platform.

[0047] 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 mains 4 respectively by built-in lifting pumps, and the sewage rises in the lifting mains 4 and is output to a designated location on the shore through the transfer mains 5 at the top of the lifting mains 4 or near the top.

[0048] Optionally, the transfer trunk pipe 5 first extends horizontally along a first direction, parallel to the dock plane, to facilitate the connection between the ship sewage receiving pontoon 3 and the sewage treatment facilities or other treatment locations on shore.

[0049] After extending horizontally for a certain distance, the transfer main pipe 5 extends vertically along a second direction, which is perpendicular to the first direction and parallel to the wharf plane. The transfer main pipe 5 repeats the above horizontal extension and vertical extension process to form a spiral path at the same elevation.

[0050] Through the design of this circulation path, the transfer main pipe 5 forms a compact layout in space, reducing the floor space and making the system more compact and efficient.

[0051] The circulation path design of the transfer main pipe 5 can greatly reduce the occupied area, which is particularly important in a dock environment with limited space.

[0052] The compact layout improves space utilization efficiency, allowing the system to efficiently complete sewage collection and transportation tasks within a limited space.

[0053] Compared with the prior art, the technical solution provided by this application has the following beneficial technical effects: The embodiment of the present application sets the first trunk receiving pipe 23 and the second trunk receiving pipe 24 on the berthing platform 1 layer by layer, so that the ship can adapt to the change of water level and connect the first trunk receiving pipe 23 and the second trunk receiving pipe 24. At the same time, a ship sewage receiving pontoon 3 that can adapt to the change of water level is set, so that the multi-berth large water level difference wharf can receive and transfer ship sewage through the corresponding berth pipeline of the wharf berthing platform 1 at different water levels and different berths, and meet the requirements of receiving and transporting oily sewage and domestic sewage of ships in layers and berths in special wharf forms; make full use of the ship pump head, solve the problem It solves the problem of insufficient ship pump head or self-priming pump suction under large water level difference, and also solves the problem of limited selection of dock sewage lifting pumps. The suction head of the self-priming pump is no longer a limiting factor, and the operation is easy; it simplifies the operation of dock staff, and the requirement of sharing a set of sewage lifting pumps for ships at multiple berths is achieved without the dock staff moving the ship sewage receiving facilities or sewage lifting pumps; it is simple to operate, with low daily maintenance requirements and low investment costs, and reduces the operating costs of ship water transit transportation when the flooding water level is low, with good economic, environmental and social benefits.

[0054] Those skilled in the art will appreciate that the various operations, methods, steps, measures, and schemes in the processes discussed in this application may be alternated, modified, rearranged, decomposed, combined, or deleted.
