Speed-regulated solar yacht

Abstract

The invention discloses a speed-regulated solar yacht which comprises a solar photovoltaic panel, a charging switch circuit, a storage battery, a motor switch circuit and a direct-current series excited motor which are connected in sequence, wherein the direct-current series excited motor is used for driving screw propellers. The speed-regulated solar yacht is provided with a charging-discharging controller, a speed regulation pedal, a sensor and a speed regulation controller, wherein the charging-discharging controller is used for collecting the output voltage of the storage battery and outputting control signals to the charging switch circuit, the sensor is used for sensing the stroke of the speed regulation pedal, and the speed regulation controller is used for collecting the signals of the sensor and outputting control signals to the motor switch circuit. When the speed of the solar yacht needs to be regulated, the operator presses the speed regulation pedal so that the sensor ends voltage signals to a voltage detection circuit in the speed regulation controller, the voltage detection circuit receives and identify the voltage signals and sends the voltage signals to a pulse width modulation circuit, and the pulse width modulation circuit changes the duty ratio of the working current of the direct-current series excited motor through the motor switch circuit. Therefore, the solar yacht is changed in speed to adapt to the needs of different occasions and users.

Description

technical field [0001] The invention relates to a yacht or a cruise ship, in particular to a yacht powered by solar cells. Background technique [0002] Solar energy is clean energy, and commonly used solar photovoltaic panels (solar panels) are formed by connecting solar cell components in series and parallel and then packaging them. Solar panels use the photoelectric effect to directly convert the sun's light energy into electrical energy, then output direct current, which can also be stored in batteries and released when needed. [0003] In a solar power generation system, a solar controller (solar charge and discharge controller) can be used in order to control the multi-channel solar battery array to charge the battery and the battery to supply power to the load. [0004] In order to make full use of solar energy and give full play to its advantages, many vehicles use solar energy as power. For example, existing yachts used for sightseeing and entertainment on the wate...

Problems solved by technology

[0006] However, the existing small yachts generally have a fixed speed, and the speed is fixed after starting, and the speed cannot be adjusted according to the needs, which is inconvenient to use.
