Description

  The present invention relates to theft prevention of a power generation unit including a solar battery panel.

  A power generation device including a solar cell panel has been proposed, and Patent Document 1 discloses a device capable of adjusting the degree of inclination of a power generation unit including a solar cell panel.

JP 2005-317588 A

  However, when the solar cell panel is tilted, a part of the solar cell panel protrudes to a high position. Therefore, even when the solar cell panel is placed on the roof, the solar cell panel may be seen from below, and there is a fear of theft. In particular, when a solar cell panel is used on the roof of a mobile house, since power consumption is small, a relatively small solar cell panel is often used, and it is necessary to consider theft prevention.

  Accordingly, an object of the present invention is to provide a power generation unit including a solar cell panel in consideration of theft prevention, or a mobile house having the power generation unit.

  The power generation unit according to the present invention allows a high-voltage current to flow based on a solar cell panel, a first frame that holds the solar cell panel, a second frame, a first battery, and power supplied from the first battery. The first frame and the second frame are made of a conductive material, and the first frame and the second frame are in a state where the first frame and the second frame are not in contact with each other. Holds the solar cell panel, one of the output terminals of the power box is connected to the first frame, and the other of the output terminals of the power box is connected to the second frame.

  A person who touches the first frame and the second frame receives a high-voltage current generated in the power box and receives an electric shock. The power generation unit is fixed with screws, etc., and is connected to indoor devices via cables, etc., so it does not come off easily, but the screws are released and the cables are cut at appropriate places. Then, it is possible to remove the power generation unit from the movable unit. However, when the power generation unit includes a power box as described above as in the present invention, it is not easy to carry and theft due to electric shock when the first frame and the second frame are touched. Can be prevented.

  Preferably, the first battery and the power box are arranged at a position hidden behind the solar cell panel or inside the first frame or the second frame.

  Since the configuration for electric shock (power box, etc.) is hidden inside the first frame, etc., even if the wiring cable for indoor use that is relatively easy to see is cut, the power supply to the power box continues. For those who do not know the structure, it is not easy to avoid electric shock.

  Preferably, the first battery stores electric power generated in a partial region of the solar cell panel.

  In this case, it is possible to prevent theft without worrying about running out of the battery. Further, the solar cell panel can be efficiently used separately for driving a power box for preventing theft and for driving a normal electric product.

  The mobile house according to the present invention provides a high voltage current based on a solar cell panel, a first frame that holds the solar cell panel, a second frame, a first battery, and a power supply from the first battery. A power generation unit having a power box that is an impact voltage generating mechanism for flowing, wherein the first frame and the second frame are made of a conductive material, and the first frame and the second frame are not in contact with each other. 1 frame and 2nd frame hold | maintain a solar cell panel, one of the output terminals of a power box is connected to a 1st frame, and the other of the output terminal of a power box is connected to a 2nd frame, In order to adjust the azimuth angle and elevation angle of the part, the roof is provided with a movable part that holds the power generation part in a movable state.

  A person who touches the first frame and the second frame receives a high-voltage current generated in the power box and receives an electric shock. The power generation unit is fixed with screws, etc., and is connected to indoor devices via cables, etc., so it does not come off easily, but the screws are released and the cables are cut at appropriate places. Then, it is possible to remove the power generation unit from the movable unit. In particular, a mobile house that can be moved by using a truck or a crane has a relatively small power generation unit, so that it can be easily removed and stolen, and it is necessary to consider theft prevention. However, when the power generation unit includes a power box as described above as in the present invention, it is not easy to carry and theft due to electric shock when the first frame and the second frame are touched. Can be prevented.

  In addition, it is possible to receive sunlight at an appropriate incident angle as compared with a mode in which the power generation unit is laid at the reference position and angle adjustment is not performed, and power generation can be performed with high power generation efficiency.

  Preferably, the movable unit is configured to electrically adjust the azimuth angle and elevation angle of the power generation unit, and the control unit drives the movable unit based on information on a place where the mobile house is installed and information on time Is further provided.

  Thereby, even if a house moves, it becomes possible to use a power generation part with the optimal power generation efficiency in the place. In addition, since the angle adjustment is automatically performed by the movable part, the user can easily optimize the degree of inclination of the power generation part.

  More preferably, the control unit drives the movable unit so that the light receiving surface of the solar cell panel of the power generation unit faces south based on the information regarding the location during the sunshine hours, and outside the sunshine hours, The movable part is driven so that the power generation part is fixed with the light receiving surface of the solar cell panel facing upward and approaching the roof of the movable house.

  When power generation based on sunlight cannot be performed, such as at night, the power generation unit can be hardly seen from a low place, and the possibility of the power generation unit being stolen can be reduced.

  In addition, preferably, the control unit, during the sunshine hours, is based on the location information and the time information, the incident angle of sunlight on the light receiving surface of the solar cell panel of the power generation unit (incident light and light receiving surface method). The movable part is driven so that the angle formed with the line becomes smaller, and outside the sunshine hours, the power generation part is fixed with the light receiving surface of the solar panel of the power generation part facing up and approaching the roof of the mobile house As described above, the movable part is driven.

  As a result, it is possible to control the degree of inclination of the power generation unit so as to track sunlight and always generate power with high power generation efficiency. In addition, when power generation based on sunlight cannot be performed at night or the like, it is possible to reduce the possibility of the power generation unit being stolen by making the power generation unit difficult to see from a low place.

  Preferably, the control unit has high power generation efficiency based on the voltage of the second battery that stores the power generated by the power generation unit and information on the power consumption of the electrical product used in the subsequent stage of the second battery. If it is determined that charging is necessary, and if it is determined that it is not necessary, the light-receiving surface of the solar panel of the power generation unit faces up and approaches the roof of the mobile house The movable part is driven so that the power generation part is fixed.

  In this case, the power generation efficiency is lower than when the angle is adjusted, but the power consumed by the electrical product is small, so there is no problem of insufficient power supply for driving the subsequent electrical product, and the low efficiency Therefore, since the power generation unit is not visible, there is a merit that the risk of the power generation unit theft is reduced.

  Preferably, the first battery accumulates electric power generated in a partial area of the solar cell panel, and electric power supplied to the control unit and the movable unit is generated in the remaining area of the solar cell panel. Based on.

  In this case, it is possible to efficiently use the solar cell panel separately for driving a power box for preventing theft and driving a normal electric product.

  In addition, preferably, an operation unit used for manually setting the elevation angle of the power generation unit is further provided, and when the elevation angle of the power generation unit is set by the operation unit, the control unit is configured to provide information on the set elevation angle. Based on the above, the movable part is driven.

  For example, when the elevation angle is set to a high angle, it becomes possible to wash away the dirt on the surface of the power generation unit (particularly the solar cell panel) with rainwater.

  A mobile house according to the present invention moves a power generation unit in order to adjust the azimuth and elevation angle of a power generation unit including a solar cell panel, a second battery that stores power generated by the power generation unit, and the power generation unit. It is a mobile house that can be carried with a movable part that is held in a possible state and a control part, and the control part is based on information about a place where the mobile house is installed and information about time The movable unit is driven, and the control unit generates power generation efficiency based on the information on the voltage of the second battery that stores the power generated by the power generation unit and the power consumption of the electrical product used in the subsequent stage of the second battery. If it is determined that it is not necessary to charge in a high state, and if it is determined that it is not necessary, or outside the sunshine hours, the light-receiving surface of the solar panel of the power generation unit The power generation unit is fixed while approaching the roof. As described above, to drive the movable portion.

  When power generation based on sunlight is not possible, such as at night, or when power generation is not necessary, it is possible to reduce the possibility of the power generation unit being stolen by making the power generation unit less visible from a low place.

  As described above, according to the present invention, it is possible to provide a power generation unit including a solar cell panel in consideration of theft prevention or a mobile house having the power generation unit.

It is a block diagram of the mobile house in 1st Embodiment. It is a perspective view of a mobile house in the state where a power generation part was put in a standard position. It is a perspective view of a mobile house in the state in which the inclination degree (1st angle (theta) 1 and 2nd angle (theta) 2) of the electric power generation part was adjusted. It is a block diagram of the mobile house in 2nd Embodiment. It is a flowchart which shows the drive control procedure in 2nd Embodiment. It is a block diagram of a mobile house when it has an operation part.

  Embodiments according to the present invention will be described below with reference to the drawings. The mobile house 1 in the first embodiment includes a power generation unit 20 (solar cell panel 21, first frame 22a, second frame 22b, first charge controller 24, first battery 25, switch 26, power box 27), first 2 charge controller 44, the 2nd battery 45, the divider | distributor 47, and the 1st movable part 51a are provided.

  The house body used in the mobile house 1 can be carried using a crane or a truck, such as a unit house or an assembly-type house. The first movable part 51a is attached to the roof, and the power generation part 20 is mounted thereon. It is attached. Other devices (second charge controller 44, second battery 45, distributor 47) are arranged in a room of the house body. However, the form which arrange | positions some of these apparatuses outside the house main body may be sufficient.

  The power generation unit 20 is a power generation device that converts light energy, such as sunlight, into electrical energy by the solar cell panel 21. A partial region (first region) of the solar cell panel 21 is connected to the first charge controller 24 via the first cable C1 and the second cable C2, and the electric power generated in the first region is 1 Used for charging the battery 25 and driving the power box 27. The remaining area of the solar cell panel 21 (wider than the second area and the first area) is connected to the second charge controller 44 via the third cable C3 and the fourth cable C4, and power is generated in the second area. The electric power thus used is used for charging the second battery 45 and for driving the electrical product in the subsequent stage of the distributor 47.

  The first frame 22a has a U-shape when viewed from the front, and the second frame 22b has an inverted U-shape when viewed from the front (a U-shape when viewed from the back). The solar cell panel 21 is held from the side surface so that the second frame 22b surrounds the outer shape of the solar cell panel 21. Both the first frame 22a and the second frame 22b are made of a conductive material, and the first frame 22a and the second frame 22b are not in contact with each other, for example, the insulating material 24 is sandwiched therebetween. The first frame 22a and the second frame 22b hold the solar cell panel 21.

  The first charge controller 24 is a charge / discharge controller that monitors the voltage of the first battery 25 and prevents overcharging from the first region of the solar cell panel 21 of the power generation unit 20 to the first battery 25. Instead of the first charge controller 24, a blocking diode that prevents a backflow phenomenon in which current flows from the first battery 25 to the first region of the solar cell panel 21 of the power generation unit 20 may be provided.

  The first battery 25 stores the electric power generated in the first region of the solar cell panel 21 of the power generation unit 20. The switch 26 is used for manual operation for controlling on / off of power supply to the power box 27.

  The power box 27 supplies a high-voltage current to the fifth cable C5 and the sixth cable 6 based on the power supplied from the first battery 25 (or the power generated in the first region of the solar cell panel 21 of the power generation unit 20). This is a mechanism for generating an impact voltage flowing in the cable C6. The anode terminal (one of the output terminals) of the power box 27 is connected to the first frame 22a via the fifth cable C5, and the cathode terminal (the other of the output terminals) of the power box 27 is connected via the sixth cable C6. And connected to the second frame 22b.

  The first charge controller 24, the first battery 25, the switch 26, the power box 27, the first cable C 1, the second cable C 2, the fifth cable C 5, and the sixth cable C 6 are on the back surface of the solar panel 21 or the first frame. It is arranged at a position hidden inside 22a or the second frame 22b. In particular, in order to make it difficult to find a device (such as the power box 27) for causing an electric shock to the person who touched the first frame 22a and the second frame 22b, it is desirable to hide them inside the first frame 22a and the like. Furthermore, it is desirable to arrange the switch 26 at a position where a person other than the user (constructor) does not know.

  When the switch 26 is in the ON state, a person who contacts the first frame 22a and the second frame 22b receives a high-voltage current generated in the power box 27 and receives an electric shock.

  The power generation unit 20 is fixed to a later-described movable unit (first movable unit 51a or second movable unit 51b) by screwing or the like, and is connected to an indoor device (third cable C3 and fourth cable C4). Since it is connected to the second charge controller 44), it cannot be easily removed. However, if the screwing is released and the third cable C3 and the fourth cable C4 are cut at appropriate locations, the power generation unit 20 can be moved. It is possible to remove from the part.

  In particular, the mobile house 1 that can be moved using a truck or a crane has a relatively small size of the power generation unit 20 to be used. Therefore, it is easy to remove and steal, and it is necessary to consider theft prevention.

  When the power generation unit 20 used in the present embodiment (first embodiment, second embodiment) includes the power box 27 as described above, the first frame 22a and the second frame 22b are touched. Because of the electric shock, it is not easy to carry around and it is possible to prevent theft.

  In particular, since the configuration for electric shock (such as the power box 27) is concealed inside the first frame 22a, etc., it is possible to connect an indoor wiring cable (the power generation unit 20 and the second charge controller 44) that are relatively easy to see. Even if the third cable C3 and the fourth cable C4) are disconnected, the power supply to the power box 27 continues, so it is not easy to avoid an electric shock for those who do not know the structure.

  In addition, if the power used in the power box 27 is configured to use power generated by the power generation unit 20 or charged in the first battery 25 as in the first embodiment, there is a risk of running out of the battery. Has no merit. Further, the solar cell panel 21 can be efficiently used separately for driving the anti-theft power box 27 (first region) and driving a normal electric product (second region). The size of the first area is set only for the area necessary for driving the power box 27, and the rest is used as the second area.

  However, the power may be supplied to the power box 27 using another power source such as a dry battery. In this case, it is necessary to periodically replace the power source (dry cell) in consideration of running out of the battery, but the power generated in all regions (first region + second region) of the solar cell panel 21 is They are all used for charging the second battery 45 and driving the electrical appliances after the distributor 47.

  The second charge controller 44 is a charge / discharge controller that monitors the voltage of the second battery 45 and prevents overcharge from the second region of the solar cell panel 21 of the power generation unit 20 to the second battery 45. Instead of the second charge controller 44, a configuration may be provided in which a blocking diode that prevents a backflow phenomenon in which a current flows from the second battery 45 to the second region of the solar cell panel 21 of the power generation unit 20 may be provided.

  The second battery 45 stores the electric power generated in the second region of the solar cell panel 21 of the power generation unit 20. The distributor 47 distributes the electric power generated by the power generation unit 20 (or the electric power stored in the second battery 45) and supplies the electric power to a plurality of DC-driven electric products (not shown, such as audio and lighting equipment).

  The first movable portion 51a includes a first rotating mechanism 51a1 and a first angle adjusting mechanism 51a2, and holds the power generation unit 20 in a movable state in order to adjust the azimuth angle and elevation angle of the power generation unit 20 ( (See FIG. 2).

  The first rotation mechanism 51a1 manually rotates on a horizontal plane parallel to the roof of the house body (rotates about an axis perpendicular to the roof) with the placed object (power generation unit 20) placed, for example, A turntable mechanism is conceivable. The amount of rotation in the azimuth direction by the first rotation mechanism 51a1 is defined as a first angle θ1 (see FIG. 3).

  The first angle adjustment mechanism 51a2 can manually change the angle (elevation angle) between the object to be placed and the horizontal plane. For example, a hinge mechanism can be considered. The amount of rotation in the elevation direction by the first angle adjustment mechanism 51a2 is defined as a second angle θ2.

  When viewed from above, when the side forming the outer shape of the power generation unit 20 placed on the first movable unit 51a and the side forming the outer shape of the roof are in a substantially parallel or substantially vertical positional relationship, the first When the rotation mechanism 51a1 is at the reference position (θ1 = 0) and the power generation unit 20 placed on the first movable part 51a is in a positional relationship substantially parallel to the roof, the first angle adjustment mechanism 51a2 is at the reference position. Suppose that there is (θ2 = 0, see FIG. 2). When the first rotation mechanism 51a1 and the first angle adjustment mechanism 51a2 are at the reference positions, the light receiving surface of the solar cell panel 21 faces upward, and the power generation unit 20 approaches the roof of the mobile house 1.

  Further, the first movable portion 51a has a lock mechanism (not shown) that can maintain the state where the power generation unit 20 is held at the desired first angle θ1 and the second angle θ2.

  When the house body is assembled or moved, the second angle θ2 is fixed to zero (θ2 = 0), that is, the power generation unit 20 is fixed in a state parallel to the roof. In this case, the first angle θ1 is not particularly limited, but it is preferable that the power generation unit 20 is fixed at the above-described reference position so that a part of the outer shape of the power generation unit 20 does not protrude from the outer shape of the roof. (Θ1 = 0).

  Until the main body of the house is installed at a predetermined position, the power generation unit 20 on the roof can be held in the reference position, so that the power generation unit 20 attached to the roof is less likely to come into contact with other obstacles. In this state, the house body can be moved. For this reason, it becomes possible to raise work efficiency compared with the form which installs power generation part 20, after a house main part is installed.

  After installing the house body, the power generation unit 20 (light-receiving surface of the solar panel 21) faces south at the place where the mobile house 1 is installed, and the incident angle of sunlight (incidence) when the sun is at the highest position. So that the angle between the light and the normal of the light receiving surface of the solar cell panel 21 is small (the angle between the incident light of sunlight and the light receiving surface of the solar cell panel 21 is nearly vertical). The installer adjusts the degree of inclination of the power generation unit 20 (first angle θ1, second angle θ2).

  Specifically, the first angle adjusting mechanism 51a2 is used to raise the power generation unit 20 obliquely so that the second angle θ2 is about 30 degrees, and the normal line of the light receiving surface of the solar cell panel 21 as viewed from above. The power generation unit 20 is rotated using the first rotation mechanism 51a1 so that the first rotation mechanism 51a1 faces south, and the first rotation mechanism 51a1 and the second angle adjustment mechanism 51a2 of the first movable unit 51a are in this state using the lock mechanism. Do not move.

  For this reason, the first movable unit 51a has an azimuth detecting device such as a azimuth magnet that can detect the azimuth and a scale indicating the angle of the second angle θ2 in order to inform the user which direction is south. It is desirable to have a device.

  The second angle θ2 may be about 30 degrees when installed in Japan, but more strictly, a value obtained by subtracting 3 degrees from the latitude at which the house body is installed (for example, in the case of 34 degrees north latitude, It is desirable to set θ2 = 31 degrees.

  As a result, it is possible to receive sunlight at an appropriate incident angle and to generate power with high power generation efficiency, compared to a mode in which the power generation unit 20 is laid at the reference position and angle adjustment is not performed. Become.

  Next, a second embodiment will be described. In the first embodiment, the form in which the angle of the power generation unit 20 is manually adjusted using the first movable part 51a has been described. However, in the second embodiment, the second movable part 51b is used to automatically generate electric power automatically. The angle of the unit 20 is adjusted. Hereinafter, a description will be given focusing on differences from the first embodiment.

  The mobile house 1 in the second embodiment includes a power generation unit 20 (solar cell panel 21, first frame 22a, second frame 22b, first charge controller 24, first battery 25, switch 26, power box 27), first 2 charge controller 44, the 2nd battery 45, the divider | distributor 47, the detection part 48, the control part 49, and the 2nd movable part 51b are provided (refer FIG. 4).

  The house body used in the mobile house 1 can be carried using a crane or a truck, such as a unit house or an assembly house. The second movable part 51b is attached to the roof, and the power generation part 20 is mounted thereon. It is attached. Other devices (the second charge controller 44, the second battery 45, the distributor 47, the detection unit 48, and the control unit 49) are arranged in a room of the house body. However, the form which arrange | positions some of these apparatuses outside the house main body may be sufficient.

  The power generation unit 20 is a power generation device that converts light energy, such as sunlight, into electrical energy. A partial region (first region) of the solar cell panel 21 is connected to the first charge controller 24 via the first cable C1 and the second cable C2, and the electric power generated in the first region is 1 Used for charging the battery 25 and driving the power box 27. The remaining area of the solar cell panel 21 (wider than the second area and the first area) is connected to the second charge controller 44 via the third cable C3 and the fourth cable C4, and power is generated in the second area. The electric power thus used is used for charging the second battery 45 and driving the electrical products (including the detection unit 48, the control unit 49, and the second movable unit 51b) in the subsequent stage of the distributor 47.

  The configurations of the power generation unit 20, the second charge controller 44, the second battery 45, and the distributor 47 are the same as those in the first embodiment.

  The second movable unit 51b includes a second rotating mechanism 51b1 and a second angle adjusting mechanism 51b2, and holds the power generation unit 20 in a movable state in order to adjust the azimuth angle and elevation angle of the power generation unit 20.

  The second rotating mechanism 51b1 is a device that rotates electrically on a horizontal plane parallel to the roof of the house body (rotates about an axis perpendicular to the roof) with the placed object (power generation unit 20) placed, for example, A turntable mechanism in which the mounting surface is rotated electrically can be considered. The amount of rotation in the azimuth direction by the second rotation mechanism 51b1 is defined as a first angle θ1.

  The second angle adjusting mechanism 51b2 can electrically change the angle (elevation angle) between the mounted object and the horizontal plane. For example, a hinge mechanism that is electrically driven and rotates around the hinge portion can be considered. The amount of rotation in the elevation direction by the second angle adjustment mechanism 51b2 is defined as a second angle θ2.

  As viewed from above, when the side forming the outer shape of the power generation unit 20 placed on the second movable portion 51b and the side forming the outer shape of the roof are in a substantially parallel or substantially vertical positional relationship, When the rotation mechanism 51b1 is at the reference position (θ1 = 0) and the power generation unit 20 placed on the second movable part 51b is in a positional relationship parallel to the roof, the second angle adjustment mechanism 51b2 is at the reference position. Suppose that there is (θ2 = 0, see FIG. 2). When the second rotation mechanism 51b1 and the second angle adjustment mechanism 51b2 are at the reference position, the light receiving surface of the solar cell panel 21 faces upward, and the power generation unit 20 approaches the roof of the mobile house 1.

  The detection unit 48 includes an azimuth detection device such as a geomagnetic sensor that measures the azimuth, and a positioning device such as GPS that measures the latitude and longitude, and information on the location where the mobile house 1 is installed includes azimuth information and latitude and longitude information Is output to the control unit 49.

  Based on the azimuth information and the latitude / longitude information, the control unit 49 turns the power generation unit 20 (the light receiving surface of the solar cell panel 21) toward the south at the place where the mobile house 1 is installed, and when the sun is at the highest position. The degree of inclination of the power generation unit 20 (the first angle θ1 and the second angle) so that the incident angle of sunlight becomes small (the angle formed between the incident light of sunlight and the light receiving surface of the solar cell panel 21 becomes nearly vertical). θ2) is calculated, and the second rotation mechanism 51b1 and the second angle adjustment mechanism 51b2 are driven so as to obtain such a degree of inclination.

  As a result, it is possible to receive sunlight at an appropriate incident angle and to generate power with high power generation efficiency, compared to a mode in which the power generation unit 20 is laid at the reference position and angle adjustment is not performed. Become. In addition, since the adjustment of the first angle θ1 and the second angle θ2 is automatically performed by the second movable unit 51b including the second rotation mechanism 51b1 and the second angle adjustment mechanism 51b2, the user can easily perform the power generation unit. The degree of inclination of 20 can be optimized.

  The control unit 49 also includes information on the voltage of the second battery 45 and transition of current flowing in the distributor 47 (information on power consumption of electrical products such as the second movable unit 51b connected to the subsequent stage of the second battery 45). ) Is detected, and based on these pieces of information, it is determined whether charging is required in a state where power generation efficiency is increased.

  For example, from the transition of the current flowing through the distributor 47, when the usage amount (power consumption) of the electrical product in the subsequent stage of the second battery 45 is small, the calculated first angle θ1 and second angle are used to increase the power generation efficiency. It is not necessary to rapidly charge the power generation unit 20 by adjusting the inclination of the power generation unit 20 to be θ2. For this reason, power generation is performed with the power generation unit 20 in the reference position.

  In this case, the power generation efficiency is lower than that in the case where the inclination degree is adjusted. However, since the power consumed by the subsequent electrical product of the second battery 45 is small, the power supply is insufficient for driving the subsequent electrical product. In addition, since the power generation unit 20 cannot be seen from a low place, there is a merit that the risk of the power generation unit 20 being stolen is reduced.

  In addition, the control unit 49 determines whether the current time is within the sunshine hours using the built-in clock function and the latitude / longitude information from the detection unit 48, and the power generation unit 20 is outside the sunshine hours. May be returned to the reference position. Specifically, the control unit 49 stores in advance a table indicating the relationship between the latitude / longitude information and time information and the position of the sun at the date and time of the point, and the latitude / longitude information, time information, and the table are stored in the table. Based on this, it is determined whether or not the current time is within sunshine hours. This is to reduce the possibility of the power generation unit 20 being stolen by making it difficult to see the power generation unit 20 from a low place when power generation based on sunlight cannot be performed such as at night.

  When the house body is assembled or moved, the second angle θ2 is fixed in a zero state, that is, the power generation unit 20 (the light receiving surface of the solar cell panel 21) is fixed in parallel with the roof or the horizontal plane. In this case, the first angle θ1 is not particularly limited, but it is preferable that the power generation unit 20 is fixed at the above-described reference position so that a part of the outer shape of the power generation unit 20 does not protrude from the outer shape of the roof. (Θ1 = 0). At this time, the maintenance of the state held at the reference position is preferably not performed by electrical drive but is performed using a mechanical lock mechanism that does not consume power.

  After installing the house body, the power generation unit 20 (light receiving surface of the solar cell panel 21) faces south in the installation location, and the incident angle of sunlight becomes small when the sun is at the highest position (sunlight The control unit 49 and the second movable unit 51b are arranged so that the inclination of the power generation unit 20 (the first angle θ1 and the second angle θ2) so that the angle formed between the incident light and the light receiving surface of the solar cell panel 21 is nearly vertical. ).

  Specifically, the control unit 49 drives the second angle adjustment mechanism 51b2 to raise the power generation unit 20 diagonally so that the second angle θ2 having the above-described inclination degree is reached, and the solar cell panel 21 as viewed from above. The control unit 49 drives the second rotation mechanism 51b1 to rotate the power generation unit 20 by the first angle θ1 so that the normal line of the light receiving surface of the second direction faces south, and in this state, the second rotation of the second movable unit 51b. The mechanism 51b1 and the second angle adjustment mechanism 51b2 are prevented from moving.

  Thereby, even if a house moves, it becomes possible to use the electric power generation part 20 with the optimal electric power generation efficiency in the place, and the electric power generation of high electric power generation efficiency is not required based on the charge state of the 2nd battery 45, etc. If it is determined that the power generation unit 20 is in a time zone where power generation cannot be performed based on sunshine hours, etc., the power generation unit 20 is placed in the reference position so that the power generation unit 20 is difficult to see from a low place. You can also.

  Note that the inclination degree (first angle θ1, second angle θ2) of the power generation unit 20 is controlled so that the incident angle of sunlight on the light receiving surface of the solar cell panel 21 is always reduced during the sunshine hours. May be. Specifically, the control unit 49 stores in advance the table (indicating the relationship between the latitude / longitude information and time information and the position of the sun at that date and time), and the latitude / longitude information and time information Based on the table, an optimum inclination degree (first angle θ1, second angle θ2) of the power generation unit 20 is calculated every certain time (for example, in units of several minutes), and the second rotation mechanism 51b1 and the second angle are calculated. The adjustment mechanism 51b2 is driven.

  For example, from sunrise to noon, the degree of inclination (first angle θ1 and second angle θ2) is controlled so that the azimuth angle of the power generation unit 20 faces from east to south and the elevation angle becomes small. Are controlled so that the azimuth angle of the power generation unit 20 is directed from south to west and the elevation angle is increased (first angle θ1, second angle θ2). Further, since the solar altitude (angle formed by sunlight and the horizon) changes throughout the year, the degree of inclination (second angle θ2) is controlled so that the elevation angle is small in summer and the elevation angle is large in winter. As a result, it is possible to control the degree of inclination of the power generation unit 20 so as to track sunlight, and to always generate power with high power generation efficiency.

  Next, drive control of the second movable portion 51b will be described using the flowchart of FIG. Such drive control is performed at regular intervals.

  In step S11, the control unit 49 acquires information regarding the voltage of the second battery 45, and determines whether or not electric power sufficient to drive the second movable unit 51b is accumulated. If the accumulated power is not sufficient and the second movable part 51b cannot be driven, the procedure is terminated. If the power generation unit 20 generates power within the sunshine hours, the power is gradually stored in the second battery 45, and thus the procedure proceeds to step S12 while this procedure is repeated several times.

  In step S12, the control unit 49 determines whether or not the current time is within the sunshine hours based on the latitude / longitude information and the time information and the above-described table. If it is within daylight hours, the process proceeds to step S13, and if it is not within daylight hours, the process proceeds to step S15.

  In step S <b> 13, the control unit 49 determines information regarding the voltage of the second battery 45 and information regarding power consumption of an electric product such as the second movable unit 51 b connected to the subsequent stage of the second battery 45. ) Is detected, and based on these pieces of information, it is determined whether charging is required in a state where power generation efficiency is high. If it is determined that charging with high power generation efficiency is necessary, the process proceeds to step S14, and if it is determined that charging is not necessary, the process proceeds to step S15.

  In step S14, the control unit 49 calculates the first angle θ1 and the second angle θ2 from the latitude / longitude information and the like, and drives the second movable unit 51b so as to be the first angle θ1 and the second angle θ2. When this drive control interval (fixed time) is short, such as a few minutes, the control unit 49 calculates the optimum degree of inclination of the power generation unit 20 during the drive control time (current time). However, when it is long, such as several hours, the control unit 49 calculates the degree of inclination of the power generation unit 20 so that the light receiving surface of the solar cell panel 21 faces south at the installation location of the mobile house 1.

  In step S15, the control unit 49 moves the movable house so that the first angle θ1 and the second angle θ2 become zero, that is, the power generation unit 20 is at the reference position, and the light receiving surface of the solar cell panel 21 faces upward. The 2nd movable part 51b is driven so that the electric power generation part 20 may be fixed in the state which approached 1 roof.

  The power generation unit 20 may use only a normal solar battery panel in both the first embodiment and the second embodiment. However, from the viewpoint of theft prevention, the above-described theft prevention is considered. It is desirable to use the structure having the above structure (solar cell panel 21, first frame 22a, second frame 22b, first charge controller 24, first battery 25, switch 26, power box 27).

  In addition, the structure of the first movable portion 51a and the second movable portion 51b can be any mechanism that can adjust the first angle θ1 corresponding to the azimuth angle and the second angle θ2 corresponding to the elevation angle. The invention is not limited to such a biaxial rotation mechanism.

  In addition, the first angle θ1 and the second angle θ2 of the second movable portion 51b are automatically set based on latitude and longitude information from the detection portion 48, and further, information on these angles is manually set. It is also possible to have a configuration having an operation unit 53 to perform (see FIG. 6).

  When the user inputs an arbitrary first angle θ1 or second angle θ2 via the operation unit 53, the control unit 49 determines the first angle θ1 or the second angle θ2 based on the input information about the first angle θ1 or the second angle θ2. 2 The movable part 51b is driven. For example, when the second angle θ2 is set to a high angle of about 50 degrees and the first angle θ1 is set so that rain from obliquely hits the surface of the power generation unit 20, the elevation angle becomes high, and rainwater causes the power generation unit 20 to It becomes possible to wash away dirt on the surface (particularly the solar cell panel 21). When the manual setting of the first angle θ1 and the second angle θ2 using the operation unit 53 is canceled (or a predetermined time has elapsed), the drive control of the second movable unit 51b by the control unit 49 is performed by the detection unit 48. Return to automatic control based on information from.
