Description

Technical Field

[0001] The present invention relates to a technology in the field of ship engineering, in particular to a relay-type transport inlaid inland electric cargo ship. Background Art

[0002] The waterway transportation industry produces significant carbon emissions and is a key area for energy conservation and emission reduction. Currently, my country has over 100,000 inland vessels, most of which are old, polluting traditional vessels. Facing severe environmental pressures, energy transformation is urgent. The rapid development of the energy storage battery industry has made it possible to use large-capacity energy storage battery equipment for inland cargo vessels. However, due to limitations in battery energy density, long-distance navigation requires mid-trip charging or battery box replacement. This time-consuming process significantly reduces shipping efficiency and places high demands on docks, waterways, and auxiliary vessels, presenting inherent disadvantages in terms of both economic efficiency and practical implementation. Therefore, conventional inland electric cargo ships, which simply replace internal combustion engines with batteries, have yet to be widely adopted due to their limited endurance. Summary of the Invention

[0003] In order to solve the problem that the existing technology only relies on connecting parts to limit the relative movement between hulls, relative movement is easily generated when the connection load increases, resulting in additional resistance and significantly reduced maneuverability, the present invention proposes a relay-type transport embedded inland electric cargo ship, which has the ability to quickly and reliably connect and quickly detach the power ship and cargo barge. The power ship can be quickly replaced without the cooperation of other auxiliary ships, which greatly reduces the power replenishment time and has high transportation efficiency; the power ship and the cargo barge are matched through a U-shaped structure, which can not only play a guiding role to facilitate connection, but also play a limiting role to provide a stable and reliable connection, so that the power ship and the cargo barge form a stable whole after connection, and the resistance performance and maneuverability are similar to those of the whole ship; the technology of rapid connection and detachment makes it feasible to replace the power ship to drive the cargo barge during navigation, realize the unlimited endurance of the electric cargo ship, and achieve long-distance transportation.

[0004] The present invention is achieved through the following technical solutions:

[0005] The present invention relates to a relay-type transport inlaid inland electric cargo ship, comprising: a power ship, a cargo barge and a connecting mechanism, wherein: the stern of the cargo barge is provided with a U-shaped groove whose shape matches the bow shape of the power ship, and its guiding function enables the power ship to sail smoothly and quickly on its own and complete the matching with the cargo barge. The limiting function of the U-shaped groove combined with the connecting mechanism of the end and the side can ensure a stable and reliable connection between the power ship and the cargo barge. After the connection, the appearance is a complete inland transport ship with a smooth hull line as a whole.

[0006] The inclined bow of the power boat can reduce sailing resistance, giving it good independent sailing performance. At the same time, there is a matching inclined surface at the docking point with the cargo barge, which plays a guiding and limiting role during connection. Combined with the connection limiting structure on the deck surface, the power boat and the cargo barge can be quickly and stably connected.

[0007] Technical Effects

[0008] The present invention combines a powerboat and a cargo barge into a smooth, linear hull. U-shaped slots at the bow of the powerboat and at the stern of the cargo barge are matched, providing a stable and reliable connection through hull positioning and connection structures. The bottom of the powerboat's bow is tilted to match the inclined end surface of the slot at the stern of the cargo barge. Compared with existing technologies, the present invention has better overall hydrodynamic performance and saves energy. The U-shaped slots on the hull and the inclined surface of the connection structure limit the position, enabling a stable and reliable connection and good maneuverability. The matching of the U-shaped slots and the inclined surface of the connection provides guidance, facilitating rapid connection. The powerboat can be flexibly configured with the cargo barge, enabling rapid connection and disconnection. This solves the problem of battery-powered ships being unable to quickly charge and replace batteries, and enables unlimited range cargo transportation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0015] like Figure 1 As shown, this embodiment involves a relay-type transport inline electric cargo ship, including: a power ship, a cargo barge and a connecting mechanism, wherein: the connecting mechanism can adopt existing technologies, such as hydraulic cylinder pushing, winch traction, pins, etc.

[0016] like Figure 2As shown, the power boat deck is of U-shaped structure, which matches the deck slot at the rear of the cargo barge; the bottom surface of the bow of the power boat is inclined inward, which matches the inclined surface of the end surface of the slot at the rear of the cargo barge; a battery box 1 is provided at the middle and rear part of the power boat deck, a living cabin 2 and a cab 3 are provided at the middle and front part, a propeller 4 is provided at the stern, and a ballast tank 5 is provided in the cabin.

[0017] The bow of the power boat is provided with a longitudinal connection mechanism 6, and the two sides of the stern are provided with transverse limit devices 7, and the connection can be achieved by using existing technology.

[0018] like Figure 5 As shown, the stern of the cargo barge is provided with a U-shaped groove 8 whose shape matches the bow shape of the power ship, so that after the power ship and the cargo barge are connected, the appearance is a complete inland transport ship with a smooth hull line as a whole.

[0019] The cargo barge is provided with a pump room 9 and a ballast tank 10 in its cabin, an anchoring device 11 is provided on the bow deck, mooring devices 12 and a large open cargo hold 13 are provided on both sides.

[0020] like Figure 1 As shown, after the barge is moored at the dock and loaded with cargo, a fully charged ballast boat approaches the barge, guided through the U-shaped slot at the rear of the barge and into the barge's slot. It then connects to the barge via a longitudinal connection mechanism, adjusting the overall draft and buoyancy of the two vessels. After connecting the two stoppers, the dock mooring is released and the voyage begins. After reaching the relay station, the vessel docks, disengages the longitudinal connection mechanism and transverse stoppers, and the ballast boat exits the barge's slot to recharge. Another fully charged ballast boat repeats the aforementioned interlocking action, relaying the entire vessel to the next stop. Depending on the voyage range and designed battery capacity, multiple relay stations can be set up, allowing the barge to maintain uninterrupted operation until it reaches its destination. During unloading, the ballast boat can detach and recharge. If the barge is empty on the return trip, it can be ballasted while unloading to ensure the propeller is submerged. The fully charged ballast boat adjusts its ballast to the appropriate draft and begins the new voyage, following the aforementioned procedures.

[0021] Simulation analysis shows that when the draft of the cargo barge and powerboat are the same, the connection can be successful even with a maximum trim difference of 4°. When the trim difference is no more than 1° and the draft difference at the connection is no more than 0.5m, the connection can also be successful. From the moment the powerboat approaches the stern of the cargo barge, in calm weather, the powerboat and cargo barge can be reliably connected within half an hour, and detached in just 5 minutes.

[0022] The above-mentioned specific implementation can be partially adjusted in different ways by those skilled in the art without departing from the principles and purpose of the present invention. The scope of protection of the present invention shall be based on the claims and shall not be limited by the above-mentioned specific implementation. All implementation schemes within its scope shall be subject to the constraints of the present invention.
