Description

Technical Field

[0001] The present invention relates to the technical field of electric ships, and more specifically, to an electric ship with a quick-install solid-state battery module. Background Art

[0002] Electric ships refer to ships that use electricity as the main or auxiliary power source. Such ships are usually equipped with battery packs, electric motors and related electric propulsion systems to achieve navigation and control of the ship. With the increasing global awareness of environmental protection, electric ships, as a clean energy ship, have received more and more attention. The use of electric ships can reduce fuel consumption and greenhouse gas emissions, and help alleviate global climate change problems. They have broad market prospects in the fields of tourism, passenger transport, logistics, etc., especially in inland rivers, lakes, coastal waters, etc. Electric ships are favored for their environmental protection, economy and flexibility.

[0003] However, the existing electric ships have the following defects: First, the core of electric ships lies in their high-efficiency battery modules, but the installation and disassembly process of these key components is relatively cumbersome, resulting in maintenance personnel facing difficult and time-consuming operations when conducting daily inspections, replacements or upgrades. This complexity not only increases operating costs, but may also delay the normal operation time of the ship and affect the overall efficiency; Second, when electric ships are sailing in waters, they will inevitably encounter wind and waves, causing the hull to be bumpy. This dynamic environment poses a severe test to the battery module. The delicate structure inside the battery module may become loose, worn or even damaged under continuous vibration and impact, thereby affecting the performance and life of the battery; Third, during navigation, especially in severe weather conditions, if the battery module is not effectively fixed, it is very easy to become unstable due to vibration, which increases the risk of battery damage; Fourth, the existing electric ships have deficiencies in the safety protection design of the battery module, lack of effective fire warning, initial fire extinguishing and isolation mechanisms. Once there is a problem with the battery module, it is often difficult to quickly and effectively control the situation, posing a major threat to personnel safety, ship structure and environment.

[0032] Refer to Figures 1-7 , this embodiment provides an electric ship with a quick - install solid - state battery module, including a hull 1. A first installation groove 2 is opened on the hull 1. The battery module 3 is loaded into the groove through the opening of the first installation groove 2. Second installation grooves 4 are respectively opened on the inner walls of the left - and - right opposite sides of the first installation groove 2. The length direction of the second installation groove 4 is perpendicular to the length direction of the first installation groove 2. And a shock - absorbing plate 5 is fixedly connected to the innermost groove wall of the second installation groove 4. A first spring 6 is fixedly connected to the outer - facing side of the shock - absorbing plate. The other end of the first spring 6 is fixedly connected to a first pressing plate 7.

[0033] More specifically, the cross - section of the shock - absorbing plate 5 is arched and bolt holes are opened at the edge of the shock - absorbing plate. A second bolt 12 passes through the bolt hole and is threadedly connected to the innermost groove wall of the second installation groove.

[0034] In the above, the shock - absorbing plate 5, the first spring 6 and the first pressing plate 7 installed in the second installation groove 4 are the shock - absorbing and stabilizing structure of the battery module 3.

The vertical vibrations are absorbed by the second springs 8 and the battery module 3 is stabilized by the second pressing plate 9. The shock-absorbing plates 5 are fixed in the second installation grooves 4 through second bolts 12.

[0049] During the travel, through the integrated battery management system, the working state of the battery module is comprehensively monitored. Once potential dangerous situations such as abnormal high temperature are detected, the emergency response mechanism will be immediately activated. The pipeline 10 is connected to the flame retardant storage tank, and is controlled to conduct through the valve, and the flame retardant substance is accurately sprayed through the nozzle 11 to quickly and effectively control the fire or high temperature threat and ensure the safe operation of the battery module 3.
