A construction method of a small inland river lithium battery power ship with modular design comprises the following steps:
step 1: designing and constructing superstructure modules; the integral appearance design mainly aims at the part above a waterline, and provides an integral appearance design scheme and an upper building interior scheme by a professional industrial design unit, and provides a plurality of upper building design schemes in advance; the superstructure module and the hull module adopt many-to-many compatibility design, namely the same superstructure module can be adapted to different main hulls, and vice versa; the superstructure module is produced by a special manufacturer and integrally transported to a shipyard;

and 4, step 4: assembling modules of the power ship; after the ship is launched, the position of the lithium battery pack is manually moved to adjust the gravity center of the whole ship and the optimal ship posture, and finally the lithium battery pack is fixedly installed; and finishing the construction of the whole ship.
And (3) when the superstructure module is designed and constructed in the step (1), the butt joint structure interface of the superstructure and the ship body and the cable piping system interface adopt standardized interface design.
When the superstructure module in the step 1 is designed and built, the weight gravity center control is mainly considered so as to facilitate the weight gravity center control of the whole ship; the ship body module splicing device is convenient to splice with ship body modules of more types.
As shown in fig. 1, firstly, modular design and construction of an upper building are carried out; the invention introduces the industrialized design of the appearance of the whole ship and the modular design of the superstructure. The functional area, the outward appearance, the decoration, functional area realization etc. that are the shipowner's demand above the main deck. For small-size lithium cell boats and ships, whole appearance design mainly is to the part above the waterline, has not influenced basically to indexes such as hull line shape, navigational speed. And the interface between the upper building of the inland river lithium battery ship and the main ship body is relatively simple, so that the technical industrial design unit can be released to provide an integral appearance design scheme and an upper building interior scheme, and various upper building design schemes are provided in advance. The shipowner can develop alone on the basis of special requirements. Such as theme development design for usage characteristics. The superstructure and hull modules are designed to be many-to-many compatible. That is, the same superstructure module can be adapted to different main hulls and vice versa; the superstructure module is produced by a special manufacturer and is integrally transported to a shipyard, so that the outfitting workload of the shipyard is greatly reduced, the components and the labor work cooperate, the overall length is taken, and the comprehensive efficiency is improved.
Secondly, carrying out modularized design and construction on the ship body; the area below the main deck for ensuring the performance of the ship is provided, namely the chassis design, the load capacity, the navigational speed, the stability and the maneuverability are realized in the area through the comprehensive balance design. The design unit of the main ship body ensures various performances of the main ship body. And for small inland river ships, the cabin below the main deck is mainly used for a propulsion system, and the modular design does not influence the functional realization of the upper part of the ship.
The method comprises the following steps of (1) designing four-way gravity center adjustment of the lithium battery pack; after determining the types of the superstructure and the chassis module, the shipowner can consider the weight and gravity center allocation in the module splicing process, but the weight statistical error and the inaccurate modeling in the actual construction process still cause a large error of the weight and gravity center allocation. And the error can be found only after the ship is launched, and the position and the model of most equipment are difficult to adjust because large-scale hoisting equipment cannot enter the cabin after the ship is launched, and the posture of the ship body can be adjusted only by adding a weight conventionally. The weight of the ship is increased invisibly, and the energy consumption during the use is also increased. The lithium batteries are relatively more flexible in arrangement, can be intensively or dispersedly arranged, can be arranged at most positions of the bilge deck, and the proportion of the weight of the batteries in the ship type to the total weight of the whole ship is larger, so that the lithium batteries are the best choice for the final gravity center allocation of the whole ship. Before the ship is launched, the lithium battery pack is designed into a non-fixed installation form and is initially and simply fixed on the I-shaped steel slide rail;
and finally, manually moving the position of the lithium battery pack after the ship is launched to achieve the optimal trim ship posture. And then fixed and installed.
Example (b):
the whole ship is divided into an upper building module and a ship body module. The design of the appearance, interior installation and the appearance coordination of the whole ship of the superstructure is responsible for professional industrial design units. The hull part is taken care of by the ship design unit.
The small-sized battery boat for inland rivers is mainly divided into a work boat and a sightseeing boat. Various superstructure and hull module designs are pre-provided for the shipowner's choice.
The task range of the working ship is engineering operation, emergency rescue and relief work, reception and the like. The environmental protection monitoring superstructure module, the fire prevention superstructure module, the hoisting and fishing superstructure module and the like can be provided. The task range of the sightseeing ship is sightseeing, and a 50 passenger position module, a 100 passenger position module, a 200 passenger position module and the like are provided. Each module can be made of different materials, including steel, aluminum alloy, composite materials and the like. For small inland river working/sightseeing ships, the superstructure is mostly 1-2 floors, the requirement on total strength is not high, and various light composite materials can be considered. The ship design unit puts forward specific requirements on indexes such as the weight, the gravity center, the lateral and transverse wind area and the like of the superstructure module. When the ship body is built, an interface of an upper building butted with a main ship body structure and a cable piping system interface are reserved.
In order to meet the purpose of many-to-many compatibility design, the interfaces of the butt joint structure and the cable piping system interface are designed by adopting standardized interfaces. And considering that the weight and the gravity center of the whole ship are controllable after docking, the upper building modules need to pay attention to the gravity center control of the weight, namely the gravity center of each upper building module needs to be controlled on a longitudinal central line as far as possible, and the weight and the vertical gravity center do not exceed the requirements of a total design unit.
The tonnage of the lithium battery power boat is mostly not more than 500 tons, and the boat body is divided into three types, namely large, medium and small, according to the tonnage.
A work boat: large (200-
Sightseeing boat: large (300-
The key of the design of the lithium battery power boat is to reduce the weight of the whole boat, improve the propelling efficiency and reduce the battery usage. Therefore, when the hull module is designed, an optimal propulsion system is configured for different hull chassises. Different chassis are equipped with different power packs to satisfy propulsion system and hull optimal match.
Designing and building a working flow, referring to fig. 1, after selecting an superstructure and a chassis module by a shipowner, a ship design unit adjusts a docking interface and finely adjusts the weight and gravity center of the whole ship; and the upper building design unit carries out final overall appearance design coordination. The superstructure module is produced by a special manufacturer and integrally transported to a shipyard, and finally assembled with the hull module.
The four-way gravity center adjustment design layout of the lithium battery pack is shown in fig. 2. And a special battery cabin is arranged on the bottom layer of the ship according to the standard requirement. According to the invention, two groups of longitudinally arranged and transversely arranged I-shaped steel or metal structures with similar shapes are pre-arranged in the battery compartment to serve as simple slide rails, and the battery cabinet is arranged on the slide rails of the battery compartment according to the initial gravity center design position when entering the compartment and is simply and fixedly arranged. After the ship is launched, the position of the battery cabinet is manually moved along the slide rail according to actual needs so as to achieve the best gravity center adjusting effect. Because of this type of vessel, trim adjustment is much more than list, only one set of battery cabinets is arranged on the transverse i-rails.
The design of the four-direction gravity center adjusting slide rail and the base of the battery cabinet is shown in figure 3. The battery cabinet adopts channel steel or similar metal structure as the mounting base, and is designed into two parallel front and back or left and right according to the arrangement direction of the slide rails. Two sets of I-steel that set up according to the base interval are as simple and easy slide rail, and the battery cabinet arranges on the slide rail, according to focus adjustment needs, adopts interim assembly pulley or other simple and easy equipment can the manual regulation battery cabinet position. And finally, fixedly welding the base and the slide rail, and removing the redundant slide rail.
