The mobile stand-alone photovoltaic power generation system according to the present invention includes a container 10, a photovoltaic module 20, and an energy storage device 30. The container 10 has a space therein and is opened through the opening / closing door 11, but only one side of the container 10 may be opened, but more preferably, the opening and closing doors 11 are installed at both sides in a horizontal direction. That is, the container 10 according to the present embodiment includes a main body having a rectangular box shape in which a bottom surface 10b, a ceiling surface 10a, and both sides are coupled, and a receiving space is formed therein, and both ends of the main body.

Each of the guide plates 12 and 13 has guide grooves 12a and 13a formed in the longitudinal direction, and a plurality of guide grooves 12 are formed in parallel at regular intervals and are installed on the ceiling surface 10a. And guide grooves 12a and 13a corresponding to each other in the second guide plate 13 installed on the bottom surface 10b are formed on the same vertical surface.

The photovoltaic module 20 is inserted into the guide grooves 12a and 13a of the first and second guide plates 12 and 13 to be accommodated at a predetermined interval in the receiving space inside the container 10.

At this time, the guide groove 13a and the bottom surface 10b of the second guide plate 13 installed on the bottom surface 10b do not have a step, but when the step occurs as in the present embodiment, When the photovoltaic module 20 is moved to the outside from the first and second guide plates 12 and 13, the photovoltaic module 20 is impacted by the step between the guide groove 13a and the bottom surface 10b. In order to prevent this from being applied, first inclined portions 14 are formed at the front and rear ends of the second guide plate 13 to form an inclined surface between the guide groove 13a and the bottom surface of the container 10b. .

In addition, when the photovoltaic module 20 is loaded on the first and second guide plates 12 and 13, the photovoltaic module 20 is prevented from being randomly moved along the guide grooves 12a and 13a. The configuration for doing so is added. Various configurations may be adopted as such a configuration, but in the present embodiment, insertion grooves 15 are formed at the front and rear ends of the second guide plate 13 in the transverse direction, and the insertion grooves 15 The stopper 16 is inserted into the insertion groove 15 to support the front and rear ends of the photovoltaic module 20 to limit movement.

In addition, when the photovoltaic module 20 is drawn out of the container 10, the step between the guide groove 13a and the bottom surface 10b of the second guide plate and the bottom surface of the container 10 ( Since a step is formed between 10b) and the ground, the step 2 must be overcome in order not to apply an impact to the photovoltaic module 20 by the step. At this time, the step between the guide groove 13a of the second guide plate and the bottom surface 10b is eliminated by the first inclined portion 14 as described above, and the bottom surface 10b of the container 10 is removed. ) And the ground are eliminated by the second inclined portion 17 formed on the stopper 16.

That is, the stopper 16 is formed with a second inclined portion 17, when the photovoltaic module 20 is loaded into the container 10 is inserted into the insertion groove 15 is a photovoltaic module ( When the solar cell module 20 is prevented from being moved and the solar cell module 20 is withdrawn, the container 10 is removed from the insertion groove 15 to enable the movement of the solar cell module 20 as well as the container 10. Located at the bottom of the opening, the photovoltaic module 20 can be safely unloaded through the second inclined portion 17 with respect to the step between the bottom surface 10b of the container 10 and the ground.

The photovoltaic module 20 is seated and accommodated in the container 10 and is drawn out through the opening and closing door 11. The photovoltaic module 20 includes a photovoltaic panel 21, a support frame 22 supporting the photovoltaic panel 21, and two mounted on top and bottom ends of the support frame 22, respectively. One or more wheels 26.

The wheels 26 are moved in the guide grooves 12a and 13a of the first and second guide plates 12 and 13 to enable easy withdrawal of the photovoltaic module 20 and accommodated therein. In the state, since the transverse movement is limited by the guide grooves 12a and 13a at the top and bottom of the support frame 22, it is possible to maintain an upright state.

In particular, since the wheel 26 is installed at the top as well as the bottom of the support frame 22, the solar power generation module 20 when the solar power generation module 20 deployed from the outside into the container 10 Even if the vertical position of the device changes, it is possible to draw in and out by cloud movement.

In addition, the wheel 26 is preferably made of a material having elasticity, which can absorb the shock applied to the photovoltaic module 20 at the time of withdrawal and deployment of the photovoltaic module 20. Rather, some elastic deformation is introduced into the guide grooves 12a and 13a of the first and second guide plates 12 and 13 to enable stable storage without lateral fluctuations.

In addition, the support frame 22 of the photovoltaic module 20 includes a leg portion 27 for placing the photovoltaic panel 21 at a predetermined inclination angle. The leg portion 27 is mounted on the upper and lower ends of the support frame 22 to separate the photovoltaic module 20 from the ground, and the long leg 27a having a relatively long length is mounted on the upper end thereof. At the bottom, a short leg 27b having a relatively short length is mounted.

By the long legs 27a and the short legs 27b, the solar panel 21 may be inclined with respect to the ground. Since the inclination angle of the solar panel 21 is determined by the length and angle of the long leg 27a and the short leg 27b with respect to the solar panel 21, the length and the angle can be adjusted. This may apply.

However, in the present embodiment, a configuration in which the solar panel 21 may be disposed at a specific inclination angle with respect to the ground is illustrated, and the solar panel 21, the long leg 27a and the short leg ( A configuration is adopted in which 27b) can maintain its angle.

In detail, the support frame 22 is equipped with a bracket 23 having a 'c' shape, and when the long leg 27a or the short leg 27b is inserted into the bracket 23, the bracket 23 is inserted into the support frame 22. The rotary pin 24 is inserted into the through-hole formed in the. In this case, a first friction piece 28 is mounted on one surface of the long leg 27a and the short leg 27b, and a second friction piece 25 corresponding to the first friction piece 28 is mounted on the bracket 23. ) Is mounted. The first and second friction pieces 28 and 25 have ends that form a curved surface to one side, as shown in a cross-sectional view along the line A-A 'in FIG. 6 (a) (FIG. 6 (b)). First and second locking pieces 28a and 25a are formed in the recesses. Therefore, before the long leg 27a and the short leg 27b are unfolded, the first and second friction pieces 28 and 25 are disposed to overlap each other, and the long leg 27a and the short leg 27b are unfolded. As the first friction piece 28 rotates together with the rotation of the long leg 27a and the short leg 27b, the first friction piece 28 comes into contact with each other as it passes over the second friction piece 25, thereby increasing the frictional force between the ends. The first and second locking pieces 28a, 25a of the two are bound together to limit further rotation. This binding can be released by the external force in the opposite direction of rotation, it can be operated only by the force of the operator without a separate tool.

In addition, as shown in FIG. 7, the photovoltaic module 20 may be configured in pairs, and in this case, the wheels 26 for moving the pair of photovoltaic modules 20. Since 4 is more stable movement and uprights are possible.

An energy storage system (ESS) 30 is electrically connected to the photovoltaic module 20 to store electricity produced by the photovoltaic module 20, and includes a battery (BATTERY) ( 31), a power conversion device (PCS) 32 and an energy management solution (EMS) 33. The energy storage device 30 is also applicable to a configuration well known to those skilled in the art, detailed description thereof will be omitted.

Next, the operation of the mobile independent solar power generation system according to the present invention will be described.

The photovoltaic module 20 loaded and stored in the container 10 is inserted into the guide grooves 12a and 13a of the first and second guide plates 12 and 13, and the photovoltaic module 20 is provided. Since the wheels 26 mounted on the upper and lower portions of the wheels 26 are inserted while partially elastically deformed, they maintain a stable upright state without lateral fluctuations.

In addition, the stopper 16 is inserted into the insertion groove 15 formed at the front and rear ends of the second guide plate 13, so that the arbitrary movement of the photovoltaic module 20 in the front and rear is limited, thereby preventing the departure from the movement. (See FIG. 2 (a)).

In this state, after moving and positioning the container 10 to a position for producing electric power, the photovoltaic module 20 is drawn out from the container 10 and deployed. That is, the opening and closing door 11 of the container 10 is opened, and the stopper 16 is removed from the insertion groove 15, and then the guide grooves 12a and 13a in the first and second guide plates 12 and 13. When moving the photovoltaic module 20 along the) is moved to the outside while moving the cloud by the wheels 26 mounted on the top and bottom.

At this time, the step between the guide groove 13a and the bottom surface 10b of the second guide plate is eliminated by the first inclined portion 14, and the step between the bottom surface 10b of the container 10 and the ground. Is eliminated by the second inclined portion 17 formed in the stopper 16 (see FIGS. 2B and 2C).

The photovoltaic module 20 drawn outward is disposed to be inclined with respect to the ground, and for this purpose, the long legs 27a and the short legs 27b constituting the leg portions 27 are rotated with respect to the support frame 22. Maintain a constant angle. That is, when the long leg 27a or the short leg 27b is rotated with respect to the support frame 22, the first friction piece 28 formed on the long leg 27a and the short leg 27b also rotates together with the rotation thereof. Through this, the friction force is generated while the surface contact with the second friction piece 25 of the bracket 23 mounted on the support frame 22 increases and eventually the first and second locking pieces at the end of each friction piece In addition to limiting further rotation by mutually binding by 25a, arbitrary reverse rotation is also limited by frictional force.

As such, the photovoltaic module 20 may smoothly receive sunlight from an energy storage device 30 including a battery 31, a power converter, and an energy management solution installed inside the container 10. It is expanded to a position, and the arrangement form is illustrated by (d) of FIG. 1 and FIG.

And the developed photovoltaic module 20 is connected to the energy storage device 30 so that the power produced can be supplied to the energy storage device (30).

In the case of moving the photovoltaic power generation system that is developed as described above to generate power, the clouds through the wheels 26 are folded by folding the leg portions 27 of the photovoltaic module 20 in the reverse order to the above-described development order. It is accommodated in the container 10 by movement ((d)-(c)-(b)-(a) in FIG. 2). Then, all the facilities for producing electric power are contained in the container 10, and such a container 10 is constructed in an easy structure for movement and storage of storage, and is mounted on a vehicle and moved to a desired position, Can be loaded and stored at storage.
