Abstract

The present invention relates to an electric propulsion ship that has developed an optimum arrangement for the power generation source of the electric propulsion ship of the prior patent registration 10-1077726.
In the present invention, a battery belonging to a relatively heavy object in a small ship is arranged on the upper surface of the main platform or necessary adjustments, a crew room, etc., not the bottom of the ship.
When placed in the bottom by such an arrangement is very difficult to maintain, especially after a certain time of use after charging, there is also a difficulty in replacement and observation of the state of the battery.
The present invention can be used as a main supply power of the propulsion motor by installing a first battery unit on the upper surface of the main platform, and can be directly used as a power source for driving various essential equipment such as a display input unit, a source, etc. of the control room.
Therefore, only the battery of the required part can be replaced, not the entire battery, and maintenance is possible without having to approach the bottom of the ship.

Description

Electric powered ship easily exchanging the batteries}

The present invention relates to an electric propulsion ship having a catamaran structure. The present invention relates in particular to an electric propulsion ship having a catamaran structure which is easily configured to maintain and maintain a battery, which is a main power supply source of the electric propulsion ship.

The present invention relates to an electric propulsion ship that has developed an optimum arrangement for the power generation source of the electric propulsion ship of the prior patent registration 10-1077726.

In electric propulsion ships such as patents, all the power for the operation of the ship is using the battery. Unlike ships using internal combustion engines, when batteries are replaced after a certain period of time, these batteries are dismantled and manually remanufactured by a person approaching the place where they are placed at the bottom of the ship in order to exchange multiple batteries at once. Ejecting to the outside. In the same way, the assembly of a new battery is also manually approached and replaced at the bottom of the ship.

The battery bottom arrangement of the battery is generally intended to have stability by placing a heavy object on the bottom of the ship so as to bias the center of gravity of the ship to the bottom of the ship as much as possible.

The electric miniature vessel of the pre-registered patent is an optimized hull in consideration of the fact that the twin-hull hull is economically capable of relatively large output and low speed due to the disadvantage of the electric motor.

However, it took considerable effort and time to replace the batteries placed at the bottom of the ship, and continued to expose the disadvantages. In other words, unlike normal ships, when fuel is injected into the fuel inlet, all the work is not completed, but the charging line should be connected to the battery to perform a long time charging operation. The battery must be replaced.

The present inventors have developed the electric propulsion vessel using the storage battery after the catamaran shown in Figures 1 and 2 as a basic hull, and the battery storage unit on the vessel bottom (bb in Figure 2) for supplying sufficient battery power In the following numerous run cycles, I found that much effort was needed to replace and repair the batteries.

In particular, the electric propulsion ship approached under the basic concept of securing the stability of the ship largely due to the battery placed at the bottom is catamaran, not single-acting. Studied.

The present invention is to provide an electric propulsion ship that is easy to use and easy to replace the device by arranging the battery which is small and heavy electric propulsion ship in the position of the top or power source rather than the bottom of the ship do.

In the present invention, a heavy battery, which was disposed at the bottom of the ship, is arranged in an exposed form on the deck of the ship.

The invention particularly facilitates replacement and repair by placing the battery in an easily accessible location on the deck.

The present invention, in particular, to arrange the battery by utilizing the space where the work hardly occurs, such as the lower chair and the back of the cabin.

According to the present invention, it is easy to maintain and maintain a battery, which is a main power source of heavy weight, on the top of a vessel, based on stability, which is an advantage of catamarans, in that maintenance is difficult due to the arrangement on the bottom of the ship.

It relates to an electric propulsion ship, characterized in that the battery storage unit which is the power generating source of the ship is disposed above the odd line (WL) of the ship.

The microprocessor MC and the battery bb are mounted inside the left and right buoyancy portions of the body portion of the present invention. However, it is not necessary to limit the positional configuration if such a microprocessor is installed on the main platform as described above instead of the left and right buoyancy unit.

Left and right propulsion motors (11) (11a) are connected to the output shaft of the intermediate power converter to enable left and right turning adjustment. If necessary, the direction of the left and right propulsion motors 11 and 11a is controlled by directly operating the drive device without installing the intermediate power converter.

In the present invention, the arrangement of the battery is that the weight center of the heavy weight in the relatively small catamaran vessel based on the total weight of the vessel is placed in the center of gravity, and the risk of overturning the vessel as a fairly dangerous ubiquitous in terms of the general vessel It made high structure impossible installation.

Furthermore, the present invention provides a battery storage unit for the first battery unit 102 of the ship's main platform 5, the second battery unit 105 for power supply of the cockpit monitor and other accessories and the chair bottom of the ship and other cargo Distributed to the third battery portion 110 to be loaded in the lower portion of the space for loading and the like.

This configuration is a stable structure by the buoyancy generating unit disposed on the left and right sides of the catamaran of the present invention that in the case of a conventional ship, it was impossible to install due to various problems due to eccentricity, which may occur while the heavy goods are placed on the deck, especially at the rear. The heavy battery can be placed closest to the propulsion motor.

This battery's proximity arrangement eliminates unnecessary power transmission losses due to shorter power transmission lines. If the power consumption is different for each propulsion motor, it is possible to maximize energy efficiency by replacing or recharging only the necessary batteries.
