Description

  The present invention relates to a small sailing vessel mainly for leisure purposes.

  In recent years, small-sized vessels for marine leisure such as fishing and cruising have been increasingly value-added, such as good ride comfort and increased storage space.

  On the other hand, since ships cannot draw electricity from the outside through transmission lines unlike houses, etc., the cabins of many small ships are not equipped with air conditioning equipment for cooling and heating, and the disadvantage that comfort is significantly lost was there.

  In other words, a comfortable cabin environment is indispensable in order to realize high added value for small ships. For that purpose, one of the problems is how to supply power to the air conditioning equipment of the cabin.

  As an improvement measure, there is an invention related to a portable air conditioner using a heat storage agent from the viewpoint of power saving (Patent Document 1).

  On the other hand, there is an invention in which a solar cell module is attached to a part of a hull from the viewpoint of power self-sufficiency and used as one of power sources (Patent Documents 2 and 3).

  The invention according to Patent Document 1 has a problem that the heat storage agent such as dry ice and ice must be transported each time, and the heat storage agent is consumed, so that the duration is limited.

  In order to generate power by sunlight, a solar cell module having a sufficient light receiving area is necessary, and the installation direction and the inclination angle are also important factors in relation to the position of the sun. In residential solar power generation of less than 10 kilowatts, a solar cell module installation area of 25 to 40 m2 (square meter) is required to generate 4 kilowatts, and the amount of power generation depends on the installation direction and inclination angle of the module. It differs 3 times or more (Non-Patent Document 1).

  That is, in the case of an air conditioner with a rated power of 1000 watts, an installation area of about 6 to 10 m 2 is required under the best installation conditions in order to generate 1000 watts. It is necessary to secure. This is a case of a silicon-based solar cell module that is general as a residential solar cell. In the case of a solar cell of a type with low conversion efficiency (for example, a dye-sensitized solar cell), a larger area is required. In order to secure such an area in a small ship with limited space, there is a problem that the stern part as shown in Patent Document 2 and the outer surface part of the cabin as shown in Patent Document 3 are not sufficient. In a ship, there is a problem that the shadow of a prop or sail hinders power generation. Further, these inventions cannot efficiently utilize the sea surface reflected light on the sea surface where the amount of reflected sunlight is large. The greater the incident angle of sunlight to the sea surface (the angle between the traveling direction of sunlight and the sea surface perpendicular) (the more sunlight enters at an angle closer to the sea surface), the greater the solar reflectance of the sea surface (so-called Fresnel). In particular, it is necessary to have an efficient solar light receiving structure in such a time zone where the solar altitude is obtained. Sea surface reflected light cannot be used at the solar panel installation position on the outer surface of the cabin as shown in Patent Document 3, and in the stern support as shown in Patent Document 2, when the sun is in the bow direction, the hull or support There is a problem that the sail or the like hinders the reception of the sea surface reflected light and the direct light.

  An object of the present invention is to provide a small sailing ship that supplies electric power necessary for cabin air conditioning by solar power generation in view of the above-described drawbacks of the prior art.

In order to achieve the above object, the present invention provides the following.
(1) A small sailing ship for leisure use, etc., comprising a power generation unit, a power storage unit, and a cabin air conditioning unit, and the power generation unit generates power with a sail part provided with a solar cell on a part of or the entire surface. A small sailing vessel characterized by that. (2) A small sailing ship characterized in that the power generation unit includes a sunlight reflection mechanism for collecting sunlight. (3) The small sailing ship, wherein the power generation unit includes a monitoring control mechanism connected to the power storage unit and the cabin air conditioning unit.

  Since the small sailing vessel according to the present invention is configured as described above, the following effects can be obtained. (1) By generating solar power in the power generation unit and supplying power to the power storage unit and the cabin air conditioning unit, it is possible to perform independent operation of the cabin air conditioning at sea, and to increase the comfort of the cabin. In addition, by providing a solar cell on the sail, it is possible to secure a power generation area necessary for cabin air conditioning even in a small ship with limited space for solar power generation. The main shipboard structure other than sail-related parts is located at a lower position than the solar power generation part, so that direct light and sea surface reflected light can be received efficiently. (2) The solar power generation unit is equipped with a solar light reflection mechanism that condenses sunlight, so that solar light is collected in the solar power generation unit regardless of changes in solar altitude and sail direction, and the amount of solar radiation required for power generation Can be secured. (3) Since the power generation unit includes a monitoring control mechanism connected to the power storage unit and the cabin air conditioning unit, the power generation amount, the power storage amount, and the power supply amount to the cabin air conditioning unit are monitored, and a desired power generation amount is obtained. If it does not reach, the sunlight reflecting part can be controlled to increase the sunlight irradiated to the power generation part.
