Description

전기추진 선박{Ship powered by the electric energy}Ship powered by the electric energy}

본 발명은 전기추진선박에 관한 것이다.The present invention relates to an electric propulsion ship.

본 발명은 특히 좌우분리구성된 추진모터에 의하여 좌우회전시 조타(操舵)장치가 필요없이 작동가능한 전기추진선박에 관한 것이다.The present invention relates in particular to an electric propulsion ship operable without the need for a steering device during left and right rotation by a propulsion motor configured to be left and right separated.

선박은 부양, 추진, 구조강도, 복원, 내항 그리고 조종기능이 일체로 되었을 때 선박으로 기본적인 기능이 발휘되어진다. 이러한 기능중 일반적으로 선박의 추진은 디젤이나 휘발유와 같은 화석연료를 연소시켜 작동하는 내연기관의 동력으로 추진기능을 발휘하며, 조종기능은 별도의 또 다른 조차장치에 의지하고 있다.A ship is to serve its basic functions as a ship when propulsion, propulsion, structural strength, restoration, inboard and steering functions are integrated. Of these functions, the propulsion of ships is usually driven by the power of internal combustion engines that operate by burning fossil fuels such as diesel and gasoline, and the steering function relies on even a separate device.

이러한 내연기관에 의한 선박은 후미에 추진모터와 프로펠러가 설치되고 이것의 추진력과 함께 설치된 조타장치에 의하여 좌우회전이 가능하다.A ship by such an internal combustion engine is provided with a propulsion motor and a propeller at the rear and can be rotated left and right by a steering device installed with its propulsion force.

따라서 내연기관의 작동에 필요한 엔진과 부대설비 그리고 연료 등의 다양한 구조물이 필요하다. 또한 조타장치로 회전하므로 부득이 선회각도가 넓을 수 밖에 없다.Therefore, various structures such as engine, auxiliary equipment, and fuel are required for the operation of the internal combustion engine. In addition, the rotation angle is inevitably wide due to the steering device.

일부 전기를 동력원으로 구동하는 선박이 있기는 하지만 내연기관의 작동불능시에 대체용, 즉 비상용으로 사용하는 것이 대부분이다. 요트와 같은 경우에도 역시 주 추진동력은 바람이며 기타 여러 선박류도 주 동력이라기 보다는 보조동력원으로 전기력을 이용하고 있다.
Some ships use some electricity as a power source, but most of them are used as replacements, i.e. for emergency use, when the internal combustion engine is inoperable. In the case of yachts as well, the main propulsion power is wind, and many other vessels use electric power as an auxiliary power source rather than the main power.

기존의 선박이 조타장치를 별도로 설치하는 경우 회전시에 많은 에너지 낭비가 있으므로 회전에 필요한 조타장치와 부대 조종설비를 전부 생략하도록 하였다.If the existing ship is equipped with a steering device separately, a lot of energy is wasted during the rotation, so all steering and auxiliary control equipment necessary for rotation are omitted.

기존의 선박은 또한 조타장치와 복잡한 구동시설에 의하여 무게가 증가하면서 조타장치가 진행중에 저항요인으로 작용하여 에너지낭비가 많다. 따라서 순수한 전기력만으로 배를 운항하기에 어려움이 많은 것을 순수한 전기력만으로 운행가능한 선박을 제공하고자 한다.Existing ships also have a lot of energy waste due to the increase in weight due to the steering system and the complex driving system, which act as resistance factors during the steering. Therefore, it is to provide a ship capable of operating only pure electric power of a lot of difficulties in operating a ship with pure electric power alone.

본 발명은 좌우에 쌍으로 배치되어진 별도의 추진모터를 설치하여 이들을 중앙연산장치로 통합제어하므로써 좌우회전이 손쉽게 가능하게 하였다.The present invention by installing a separate propulsion motor arranged in pairs on the left and right by the central control unit integrated control to enable easy left and right rotation.

본 발명은 좌우회전을 위한 조타장치를 삭제하여 무게의 감소와 회전에 따른 에너지 낭비 그리고 회전반경이 최소화하게 하였다.The present invention eliminates the steering device for the left and right rotation to reduce the weight and energy waste and rotation radius by the rotation.

본 발명은 파워트리거신호, 핸드브레이크신호, 핸들의 작동시 발생하는 앵글센서의 신호, 트로틀밸브신호, 전후진신호, 현재좌표신호, 밧데리전원신호들이 마이크로프로세서에 의하여 통합연산되어져, 좌우회전이 용이하며, 특히 구동을 위한 에너지 소모가 극소화한 전기추진선박이 가능하게 되었다.According to the present invention, the power trigger signal, the hand brake signal, the angle sensor signal generated when the steering wheel is operated, the throttle valve signal, the forward and backward signal, the current coordinate signal, and the battery power signal are integrated by a microprocessor, so that the left and right rotations are easy. In particular, electric propulsion ships with minimal energy consumption for driving are now possible.

본 발명은 특히 좁은 항구 혹은 좁은 수로에서 제자리에서 360도회전도 가능하여 다양한 종류의 선박에 적용이 가능하다.In particular, the present invention can be applied to various types of ships by being able to rotate 360 degrees in place in a narrow port or narrow waterway.

본 발명은 또한 복잡하면서도 진행중에 저항으로 작용하는 조타장치자체가 없어 효율이 높아지게 되었다.The present invention is also complicated and there is no steering device itself acting as a resistance during the process, the efficiency is increased.

본 발명의 선박은 또한 필요시 선박에 설치되어지는 태양광발전패널을 함께 병용하여 비교적 원거리운행도 가능하게 할 수 있다.The ship of the present invention can also be used in combination with a photovoltaic panel that is installed on the ship, if necessary, to allow relatively long distance operation.

본 발명은 조타장치가 없이 중앙연산장치에 의하여 좌우회전이 용이하면서 에너지 낭비가 없는 전기추진선박에 관한 것이다.The present invention relates to an electric propulsion ship that is easy to turn left and right by a central computing device without a steering device and does not waste energy.

Adjustment,

상기한 조정부의 핸들과 악셀부의 신호, 현재 진행중인 배의 속도, 방향 그리고 추진구동부의 추진모터의 방향 신호를 입력받아 연산후 추진모터에 제어신호를 송신하도록 하는 제어부로 구성되어진 전기추진 선박에 관한 것이다.It relates to an electric propulsion ship composed of a control unit for receiving the signal of the steering wheel and the axel section of the control unit, the speed and direction of the current ship and the direction signal of the propulsion motor of the propulsion drive unit and transmits a control signal to the propulsion motor after the calculation. .

본 발명에서 보디부의 좌우부력부는 내부가 중공구조이거나 혹은 내부가 발포합성수지와 같은 다공성의 발포체 혹은 금속제의 중공구조물들이 이용가능하며이, 부력을 주는 동시에 선박에 대한 구조적 기능을 겸비하는 것이다이렇게 구성된 좌우의 부력부는 메인플렛폼(5)의 좌우측단부(6)(7)의 하부 체결부(8)(9)에 의하여 체결과 해체가 임의로 가능하게 하였다. 메인플렛폼은 가장 흔한 구조물로 목재, 합성수지재 혹은 금속재를 이용하여 좌우의 부력부를 서로 일체화하는 것이면 특별히 제한을 둘 필요는 없다. 메인플렛폼의 상부에는 승선을 위한 공간과 조종공간 그리고 조작장치들이 배치되어진 조정부가 설치되어지도록 구성한다.In the present invention, the left and right buoyancy portion of the body portion is a hollow structure or the inside of the porous foam or metal hollow structures, such as a foamed synthetic resin is available, which gives a buoyancy and also has a structural function for the ship The buoyancy portion was able to be arbitrarily fastened and disassembled by the lower fastening portions 8 and 9 of the left and right end portions 6 and 7 of the main platform 5. The main platform is the most common structure, and if the buoyancy parts of the left and right are integrated with each other by using wood, resin, or metal, there is no need to limit in particular. The upper part of the main platform is configured to be equipped with a control unit in which a space for boarding, control space and control devices are arranged.

이렇게 구성된 보디부의 좌우부력부의 내부에는 마이크로프로세서(MC)와 밧데리(bb)들이 적재되어진다. 그러나 이러한 마이크로프로세서가 좌우부력부가 아니라 상기한 메인플렛폼에 설치되어져 동일한 기능을 한다면 위치적 구성을 제한할 필요는 없다. 본 발명에서의 또 다른 특징은 상기한 밧데리가 재충전가능한 것으로, 보디부의 상측에 설치되어지는 태양광발전장치로부터 에너지를 충전할 수 있도록 하는 것이다. 전기를 에너지원으로 일정한 거리를 진행하고 나서 정지중일 경우 보디부의 갑판상면을 덮고 있는 태양광판넬을 최대한 확장하여 밧데리에 대한 충전작업을 가능하게 하는 것이다. The microprocessor MC and the battery bb are mounted in the left and right buoyancy portions of the body portion configured as described above. 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. Another feature of the present invention is that the battery is rechargeable, so that it is possible to charge energy from the photovoltaic device installed above the body portion. After a certain distance from the electricity source to the energy source, the solar panel covering the top surface of the deck of the body portion is extended to the maximum to enable the charging operation for the battery.

이러한 마이크로프로세서는 파워트리거신호(P), 핸들의 작동시 발생하는 앵글센서(S)의 신호, 트로틀밸브신호(Th), 전후진신호(F)(I), 핸드브레이크신호(H)들이 인버터(IV1)(IV2)의 입력포트에 입력되어지며, 상기한 입력신호들을 이 인버터(IV1)(IV2)에서 연산하여 출력포트(M1)(M2)(M3)과 (M4)(M5)(M6)로 출력하여 좌.우추진모터(11)(11a)를 조정하며, The microprocessor includes a power trigger signal (P), an angle sensor (S) signal generated during operation of the handle, a throttle valve signal (Th), forward and backward signals (F) (I), and a hand brake signal (H).

To adjust the left and right propulsion motors 11 and 11a.

상기한 인버터(IV)(IV2)는 라인컨트랙터(LC)를 중간에 배치하여 동력밧데리(bb)에 신호연결되어지며, The inverter (IV) (IV2) is arranged in the line contractor LC in the middle is connected to the signal to the power battery (bb),

상기한 출력포트(M1)(M2)(M3)과 (M4)(M5)(M6)에는 동일한 엔코더1과2(E1)(E2)가 설치되어져 상기한 좌.우추진모터(11)(11a)의 회전속도와 방향에 대한 신호를 입력하도록 제어부를 구성한다.The same encoders 1 and 2 (E1) and E2 are provided at the output ports M1, M2, M3 and M4, M5 and M6, and the left and right propulsion motors 11 and 11a are provided. The control unit is configured to input a signal about the rotation speed and the direction of.

본 발명에서 추진구동부의 죠인트부(12)는 인버터1과 2에서 송출되어오는 제어신호에 의하여 작동하는 직류 혹은 교류모터 혹은 스텝모터와 같은 구동장치(12a)를 설치하며, 이 모터의 출력축에 별도의 워엄기어, 베벨헬리컬기어 혹은 랙크앤드피니언 기어와 같은 중간동력변환장치(12b)로 구성된다. 중간동력변환장치의 출력축에 좌.우추진모터(11)(11a)가 연결되어져 좌우선회조정이 가능하게 한다. 필요에 따라서는 상기한 중간동력변환장치를 설치하지 않고 직접 구동장치를 작동시켜 좌.우추진모터(11)(11a)의 방향을 제어하는 것도 가능하다.In the present invention, the joint part 12 of the propulsion drive part is provided with a driving device 12a such as a direct current or an alternating current motor or a step motor, which is operated by control signals transmitted from inverters 1 and 2, and is separately provided on the output shaft of the motor.

If necessary, it is also possible to control the direction of the left and right propulsion motors 11 and 11a by directly operating the drive device without installing the above-described intermediate power converter.

이상의 구성에 따른 본 발명의 동작관계를 설명한다.The operation relationship of the present invention according to the above configuration will be described.

도 5 에 도시하듯이 모터(11)(11a), 인버터1,2(IV1)(IV2), 밧데리(bb),라인컨트랙터로 구성되어 있듯이, 인버터1,2는 구동체인 모터와 체결되고, 구동 전원인 밧데리직류 전원와 연결되어 있다. 밧데리는 인버터 제어기와 노이즈감전 방지노이즈제어기 회로 보호를 위하여 라인컨트랙터(LC)에 의하여 절연 제어된다. 그리고 이라인컨트랙터에 제어신호가 입력되면 온(on)된다. 스위치(P)이 온되면 제어신호를 위한 제어기 전원이 통전(通電)되면서 인버터1,2 가 동작한다. 스위치가 온되고 나서 반드시 라인컨트랙터에 제어 신호를 인가해서 밧데리 주 전원을 인가한다. 즉스위치가 동작된 후 라인컨트랙터에 제어 신호를 인가하는 순서로 되어야 한다. 인버터1 과 인버터2 는 서로 통신하여 상태를 점검한다. As shown in Fig. 5, the motors 11 and 11a, the inverters 1 and 2 (IV1) and IV2, the battery bb, and the line contractor, the inverters 1 and 2 are engaged with the motor, which is the drive chain, and driven. It is connected to battery DC power. The battery is insulated and controlled by the line contractor LC for the protection of the inverter controller and the noise control circuit. When the control signal is input to the line contractor, the control signal is turned on. When the switch P is turned on, the inverters 1 and 2 operate while the controller power supply for the control signal is energized. After the switch is turned on, always apply the control signal to the line contractor to supply the battery main power. That is, after the switch is operated, the control signal should be applied to the line contractor. Inverter 1 and inverter 2 communicate with each other to check their status.

도 5에 도시하듯이 전진, 후진 제어 단자는 예를 들어 전진인 경우 두 개 모터가 동시에 같은 시계 방향으로 회전한다. 후진의 경우라면 두 개 모터가 동시에 같은 반 시계 방향으로 회전한다.As shown in Figure 5, the forward and reverse control terminals , for example, in the case of the forward two motors rotate in the same clockwise direction at the same time. In reverse, both motors rotate in the same counterclockwise direction.

속도 세기 신호는 두 개 모터의 회전속도를 똑같이 제어한다. 구체적으로는 가변저항과 같은 장치를 설치하여 악셀레이터의 답압력이나 회전각도에 따른 저항의 변이로 모터에 대한 전원의 공급을 조절하여 속도를 제어한다. The speed velocity signal controls the rotation speed of the two motors equally. Specifically, by installing a device such as a variable resistor to control the speed by adjusting the supply of power to the motor by the variation of the resistance according to the response pressure or rotation angle of the accelerator.

아래 구간에서는 위의 속도 세기 신호에 지배된다. 즉 예를 들어 1000rpm 으로 모터 두 대가 모두 회전한다면 앵글센서(22a)에서 각도는 1000rpm 이내에서 회전하는 것이다.The lower section is governed by the velocity velocity signal above. That is, for example, if both motors rotate at 1000 rpm, the angle in the angle sensor 22a rotates within 1000 rpm.

도시하듯이 구간C의 경우 중립에 위치하는 일정 구간이다.As shown, section C is a certain section located in neutral.

이 구간에서는 후진 제어단자와 속도제어 신호에 의해서 제어된다. This section is controlled by the reverse control terminal and the speed control signal.

b구간에서는 c구간 이후 모터1 과 2가 같은 속도로 동시에 회전하다가 모터2(11a)가 감속하기 시작한다. 즉 모터 11a가 감속하므로 모터 11 보다 모터 11a의 속도가 느리므로 모터의 속도 불균형에 의해 보트는 직진하지 못하고 좌로 움직이게 된다.In section b, after motor c and motor 2 rotate simultaneously at the same speed, motor 2 (11a) starts to decelerate. That is, since the motor 11a is decelerated, the speed of the motor 11a is slower than that of the motor 11, so the boat cannot move straight due to the speed imbalance of the motor.

d 구간에서는 c구간 이후 모터들이 같은 속도로 동시에 회전하다가 모터11a가 감속하기 시작한다. 즉 모터11a가 감속하므로 모터11보다 모터11a가 속도가 느리므로 모터의 속도 불균형에 의해 보트는 직진하지 못하고 보트가 우로 움직이게 된다.In section d, after section c, the motors rotate at the same speed and motor 11a starts to decelerate. That is, since the motor 11a decelerates, the motor 11a is slower than the motor 11, so the boat cannot move straight due to the speed imbalance of the motor.
