Description

  The present invention relates to a mobile solar power generation device capable of changing an installation location.

  In recent years, there has been an increasing demand for mobile solar power generation devices that can change the installation location, and various types of structures and functions have been proposed. There are "mobile solar power generator", "movable solar battery" described in Patent Document 2, or "mobile solar system" described in Patent Document 3 (hereinafter collectively referred to as "solar power generator").

  In the “photovoltaic power generation apparatus” described in Patent Document 1, since the photovoltaic power generation panel can be raised and lowered, the attitude of the photovoltaic power generation panel can be adjusted according to the height of the sun. In order to change the orientation of the photovoltaic panel, the entire device must be swung on the installation surface, so it is difficult to follow the direction of the sun, which changes greatly from sunrise to sunset.

  On the other hand, in the “photovoltaic power generation device” described in Patent Documents 2 and 3, since the wheels are provided on the structure that supports the photovoltaic power generation panel so that it can be raised and lowered, the orientation of the horizontal photovoltaic power generation panel can be changed. Although relatively easy, it is not suitable for a photovoltaic power generation apparatus that requires a large photovoltaic panel.

  In other words, the “solar power generation device” described in Patent Documents 2 and 3 is a system that supports the weight of the entire device by wheels that directly contact the installation surface, and therefore has a large and heavy solar power generation panel. As a result, the weight of the entire device is concentrated only on the wheel, and after installation at a predetermined location, the installation surface may be recessed due to a load applied concentrated on the installation surface from the wheel, which may impair stability.

  The problem to be solved by the present invention is that the installation location can be moved, the attitude of the photovoltaic power generation panel can be changed according to the direction of the sun, and the stability after installation is also good. It is to provide a power generation device.

  The solar power generation device of the present invention includes a circular track that can be placed on an installation surface, a pedestal that supports the photovoltaic power generation panel in a undulating manner, and the pedestal that rotatably supports the circular track along the circular track. A rotating member or a sliding member interposed between the circular track and the gantry is provided.

  With such a configuration, the solar power generation device is carried to a predetermined installation place, a circular track is placed on the installation surface, a mount is placed thereon, and the inclination angle and direction of the solar power generation panel are set. It can be operated just by adjusting. That is, the photovoltaic power generation apparatus according to the present invention can be used by simply carrying it to an arbitrary installation location and performing the above-described operation, and thus the installation location can be moved.

  In addition, the solar power generation panel supported by the gantry so that it can be raised and lowered not only can change the inclination angle, but also can rotate along the circular orbit along with the gantry, so that the solar panel corresponds to the direction of the sun. The posture of the power generation panel can be changed.

  Furthermore, since the weight of the gantry supporting the photovoltaic power generation panel is applied to the installation surface in a state of being distributed over the entire circular track via the rotating member or the sliding member, the installation surface is dented or sunk due to the concentration of the load. The stability after installation is also good.

  Here, it is desirable to provide a detachable locking means for preventing rotation of the gantry with respect to the circular track.

  With such a configuration, since the gantry after rotating along the circular track and adjusting the orientation of the photovoltaic power generation panel can be locked by the locking means so as not to rotate from the position, The posture of the power generation panel can be stably maintained. Further, if the locking means is released, the gantry can be rotated along the circular track, so that it is easy to readjust the direction of the photovoltaic power generation panel.

  In addition, a liquid tank capable of storing and discharging liquid can be provided on the gantry.

  With such a configuration, after installing the photovoltaic power generation device, by injecting a liquid such as water into the liquid tank, the liquid tank can function as a weight of the gantry, which is effective for improving stability. It is. In addition, if the liquid in the liquid tank is discharged, the weight is reduced, so that the workability at the time of moving, installing, or removing the solar power generation device is not hindered.

  Furthermore, a rotating body that movably supports the solar power generation device can be provided on the circular track. With such a configuration, workability when the solar power generation device is transported to the planned installation surface is improved.

  According to the present invention, it is possible to provide a photovoltaic power generation apparatus that can move the installation location, can change the attitude of the photovoltaic power generation panel corresponding to the direction of the sun, and has good stability after installation. Can do.

  A photovoltaic power generation apparatus 100 shown in FIG. 1 includes a circular track 10 that can be placed on an installation surface F, a gantry 20 having a quadrangular plan view shape that supports a rectangular photovoltaic power generation panel 30 in a undulating manner, And a plurality of wheels 21 which are rotating bodies mounted between the circular track 10 and the gantry 20 so as to be movable along the circular track 10. The plurality of wheels 21 are rotatably supported by support portions 26 protruding from corner portions of the gantry 20.

  The solar power generation panel 30 has a front edge portion 31 rotatably attached to the upper surface of the front edge portion 22 of the gantry 20 via a hinge member 32. The upper end portion of the rod-shaped stay member 23 is pivotally supported at a portion near the corner portion 33 on the back surface of the photovoltaic power generation panel 30 so that the up-and-down movement is possible. The lower end portion of the stay member 23 is a female screw portion (not shown). Are supported by a slider 24 having a zigzag).

  The slider 24 is screwed into a male screw member 27 that is rotatably arranged in a horizontal direction orthogonal to the front edge portion 31 of the photovoltaic power generation panel 30, and the male screw member 27 that protrudes from the rear edge portion 28 of the gantry 20. An operation handle 29 for rotating the male screw member 27 is provided at the rear end.

  When the operation handle 29 is rotated forward / reversely, the photovoltaic power generation panel 30 undulates along the arrow A direction. The photovoltaic power generation panel 30 can rise and fall within the range of the upright standing state and the horizontally lying down state, and can be held at an arbitrary inclination angle within this range.

  The support portion 26 protruding from the corner portion of the gantry 20 is provided with a detachable locking means 19 for preventing the wheels 21 from moving along the circular track 10. The locking means 19 holds the guide tube 19a fixed to the support portion 26, the locking rod 19b inserted into the guide tube 19a so as to be movable up and down, and the locking rod 19b in the locking position and the release position, respectively. And a stopper (not shown). When a rotational force along the direction of the circular track 10 is applied to the gantry 20 in a state where the locking means 19 is released, the gantry 20 has an arrow centered on the vertical center line C (the center line of the circular track 10). It rotates in the direction of line B.

  Here, the usage of the solar power generation device 100 will be described. The solar power generation device 100 is carried to the installation planned place, the circular track 10 is mounted on the installation surface F, and the gantry 20 is mounted with the wheels 21 in contact therewith. Thereafter, the horizontal direction of the photovoltaic power generation panel 30 is set appropriately by rotating the gantry 20 in the direction of the arrow B, the locking rod 19 of the locking means 19 is lowered, and the lower end thereof is circular. When engaged with the track 10 and held by a stopper (not shown), the gantry 20 is fixed at that position.

  Then, if the operating handle 29 on the rear edge portion 28 side of the gantry 20 is rotated and the photovoltaic power generation panel 30 is raised and lowered in the direction of arrow A so that the inclination angle is appropriately set, the photovoltaic power generation device 100 is ready for operation. In addition, adjustment of the direction and inclination angle of a photovoltaic power generation panel can also be performed in the reverse procedure to the above.

  As described above, the solar power generation device 100 can be used by moving it to an arbitrary installation location and performing the above-described operation, so that the installation location can be moved. Further, the photovoltaic power generation panel 30 supported by the gantry 20 so as to be able to undulate can not only change the inclination angle but also rotate along the circular orbit 10 together with the gantry 20, so that it corresponds to the direction of the sun. Then, the attitude of the photovoltaic power generation panel 30 can be changed.

  Furthermore, since the weight of the gantry 20 that supports the photovoltaic power generation panel 30 is applied to the installation surface F in a state of being distributed over the circular track 10 through the plurality of wheels 21, the weight is concentrated on the installation surface F due to the concentration of the load. And subsidence can be suppressed, and stability after installation is also good.

  Further, by providing the detachable locking means 19 that prevents the wheels 21 from moving along the circular track 10, the direction of the photovoltaic power generation panel 30 is adjusted by rotating along the circular track 10. Since the rear base 20 can be locked by the locking means 19 so as not to rotate from the position, the posture of the photovoltaic power generation panel 30 can be stably maintained. Further, if the locking rod 19b is lifted and detached from the circular track 10 and the locking means 19 is released, the gantry 20 can be rotated along the circular track 10, so that the orientation of the photovoltaic power generation panel 30 is restored. Adjustment is also easy.

It is. Further, if the liquid in the liquid tank 40 is discharged, the weight is reduced, so that the workability at the time of moving, installing, or removing the photovoltaic power generation apparatus 200 is not hindered.

  Since the plurality of liquid tanks 40 are connected to each other by the communication pipe 41, the liquid is injected into and discharged from the whole of the plurality of liquid tanks 40 by injecting and discharging the liquid into any one of the liquid tanks 40. be able to.
