1 and 2, a one-axis-driven photovoltaic power generation system having an inclined structure according to a preferred embodiment of the present invention includes a pole 10 and a pole which are fixed on a ground such as a photovoltaic power generation site. (10) is provided on the lower portion of the photovoltaic panel 20 and the photovoltaic panel 20 installed at the top of the rotation to rotate the photovoltaic panel 20 while changing the angle of incidence of the sun to the photovoltaic panel 20 Includes device 30.

The pole 10 is vertically erected and the lower end is fixed and installed on the upper end of a predetermined weight block by a fastening means such as an anchor bolt. Preferably, the pole 10 may be made of a metal tubular body with a round outer circumference, such as a conventional street lamp post, and may be configured with various other materials and shapes.

When the photovoltaic power generation site is a place where trees exist, such as a mountainous area, a forest, a fallow, etc., when constructing a photovoltaic system, a plurality of poles 10 are arranged to be spaced apart from each other at a predetermined interval so that trees can be located in the vicinity. Can. In addition, as a photovoltaic power generation site to which the present invention can be applied, if at least one predetermined weight block is buried and only a small vacant lot capable of erecting a pole 10 on the weight block is secured around the factory or residential area, Various places can be employed, such as around the park.

The solar panel 20 is installed on the top of the pole 10 to produce solar electricity. The solar panel 20 is fixed to the inclined surface of the flange 31 formed obliquely at one end of the rotating device 30 of the rotating device 30 and is installed to be inclined with respect to the ground.

The solar panel 20 is disposed to be inclined so that the installation angle θ1 with respect to the ground is inclined toward the ground, and rotated by the rotating device 30 so that the inclination angle and the azimuth angle with respect to the sun can be adjusted. The installation angle θ1 of the solar panel 20 is determined by the inclined angle of the inclined surface of the flange 31 formed obliquely at the top of the rotating device 30.

The rotating device 30 is connected to the rear of the solar panel 20 and gradually rotates the solar panel 20 around an axis of rotation (rotation center) A1 inclined with respect to the ground. To this end, the rotating device 30 preferably includes a driving motor 35 arranged such that the rotating shaft is inclined upwardly from the ground. The drive motor 35 of the rotating device 30 may be disposed such that the rotation shaft provided thereon coincides with the rotation axis A1, but it goes without saying that the present invention is not limited to this configuration. Alternatively, various known gear assemblies for power transmission may be added between the drive motor 35 and the solar panel 20.

The bending part 40 is provided at the lower portion of the rotating device 30 and is configured to arrange the rotating device 30 at a predetermined angle with respect to the pole 10, so that the incident angle of sunlight during rotation of the solar panel 20 It acts to change. The bending part 40 may be provided by partially bending (bending) the upper part of the pole 10 connected to the rotating device 30 at a predetermined bending angle θ2. Alternatively, the bending portion 40 may be provided by providing an extension portion of a predetermined length at the lower end of the rotating device 30 and slightly bending the extension portion at a predetermined bending angle θ2.

The direction in which the bending portion 40 is bent is preferably opposite to the inclined direction of the solar panel 20. According to this configuration, as the photovoltaic panel 20 gradually rotates in one direction by the rotating device 30, the inclination angle of the photovoltaic panel 20 naturally changes, so that the inclination angle can be set differently for each time zone. That is, when the installation angle (θ1) with respect to the ground of the solar panel 20 is, for example, 30° and the bending angle (θ2) of the bending unit 40 is set to 15°, the solar panel 20 is, for example, It can be arranged to be tilted at a gentle angle of inclination of 15° (= 30°-15°) at noon time. When the solar panel 20 is rotated by the rotating device 30 to move toward the east in the morning or toward the west in the evening, the angle changes so that the angle is inclined at a relatively steep inclination angle of 30° toward the ground. The solar panel 20 may be arranged at an inclination angle corresponding to the incident amount of each unit.

In this regard, in FIGS. 3(a) to 3(e), the rotating device 30 rotates clockwise in a bent state by the bending part 40, so that the inclination angle and azimuth angle of the solar panel 20 gradually decrease over time. An example of adjustment is shown. Specifically, in (a) of FIG. 3, when the solar panel 20 is, for example, facing east, by the rotating device 30 and the bending part 40, it is inclined at a steep inclination angle of 30°. ), the photovoltaic panel 20 rotates clockwise to change the inclination angle more gently, and in FIG. 3(c), the photovoltaic panel 20 moves 15° toward the south at noon when the sun is high. The state in which the inclination angle is changed to be gently inclined is illustrated. In addition, in (d) of FIG. 3, when the solar panel 20 is further rotated, the inclination angle is changed to be more inclined, and in FIG. The state in which the inclination angle is changed to incline in degrees is shown. As described above, when the solar panel 20 rotates horizontally in the clockwise direction, the tilt angle of the solar panel 20, that is, the incident angle of the sun changes automatically, the rotating device 30 is bent against the pole 10 It is a result of rotating in a bent state by the unit 40.

As described above, the solar panel 20 is gradually rotated by the driving motor 35 of the rotating device 30 so that the azimuth angle of the solar panel 20 is adjusted, and at the same time, the sunlight on the ground by the bending unit 40 is applied. The angle of incidence of the sun may be adjusted by changing the inclination angle of the panel 20.

The first tubular body 33 is a pipe-like structure connected to the lower end of the flange 31 and having a circular circumferential surface. The first tubular body 33 and the flange 31 may be integrally formed, or alternatively, it is also possible that the flange 31 at the top of the first tubular body 33 is integrated by welding.

The second tubular body 34 is a pipe-like structure assembled to be located under the first tubular body 33 and having a circular circumferential surface. A circular slot into which the upper pipe structure of the pole 10 can be fitted may be added to the lower end of the second tubular body 34. As the pole is fitted into the hollow, the second tubular body 34 is fixed to the top of the pole 10.

Since the bearing is interposed between the first tubular body 33 and the second tubular body 34, structurally stable and smooth rotation can be achieved. The bearing has an upper ring connected to the first tubular body 33 to rotate integrally, and a lower ring assembled to the lower portion of the upper ring and connected to the second tubular body 34, and the upper ring Multiple balls may be interposed between the lower rings.

In addition, as shown in FIG. 4, the rotating device 30 includes a rotating gear 62 substantially connected to the first tubular body 33 and a fixed gear 61 substantially connected to the second tubular body 34. Wow, the driving motor 35 is installed to be connected to the fixed gear 61 to provide a rotational force to the rotating gear 62, and is disposed under the rotating gear 62 to rotate integrally with the rotating gear 62 A count switch 63 and a limit switch 60 fixed to the fixed gear 61 to maintain contact with the rotating count plate 63 when the rotating gear 62 rotates are provided.

The rotating gear 62 is installed to be rotated relative to the fixed gear 61 by receiving the rotational force from the driving motor 35. The rotating gear 62 and the fixed gear 61 may be composed of various known gear assemblies.

The drive motor 35 is preferably fixed to the center of the second tubular body 34 to be coaxial with the second tubular body 34 to provide rotational force to the rotating gear 62.

The rotating count plate 63 is fixed to the lower portion of the rotating gear 62, rotates simultaneously with the rotating gear 62, and has an uneven pattern consisting of a valley (or groove) and a floor (or protrusion) structure while going circumferentially at the bottom. It is formed of.

The limit switch 60 has one side fixed to the fixed gear 61 and the other side contacting the rotating count plate 63 to maintain contact with the uneven pattern simultaneously with the rotation of the rotating count plate 63. Therefore, as the rotation count plate 63 rotates, an on/off signal is repeatedly output from the limit switch 60.

5 and 6, the contact portions of the first tubular body 33 and the second tubular body 34 include

first contact points

36a, 36b and second contact points for transmission of power and/or signals ( 38a, 38b) are installed. The

first contact points

36a, 36b and the

second contact points

38a, 38b are each composed of at least one conductor ring, and are fixed to the first tubular body 33 and the second tubular body 34, respectively, to face up and down. Is placed. While the first tubular body 33 rotates with respect to the second tubular body 34, the

first contacts

36a, 36b are elastically biased downward by the coil spring 37, and the

second contacts

38a, 38b ). Alternatively, one of the first contact and the second contact is configured as a roll, and the other is composed of a conductor ring that the roll can roll, so that the first contact and the first contact are made when the first tubular body 33 is rotated. The two contacts can be configured to maintain contact while rolling relatively.

Alternatively, as shown in FIG. 7, a wire 39 for transmitting power or a signal may be connected between the first tubular body 33 and the second tubular body 34.

The microcomputer determines the daily rotation amount of the solar panel 20 based on a predetermined illuminance sensor, a seasonal rotation setting time, and GPS time information provided by the satellite communication module, and turns the driving motor 35 on. It can be applied to on/off control to perform rotation control. The microcomputer may be embedded in the rotating device 30 or the pole 10 and may be embedded in a separate enclosure.

The micom recognizes that the day is bright when the illuminance value of the sunlight output from the illuminance sensor exceeds a predetermined value, and operates the driving motor 35 of the rotating device 30 to operate the solar panel for a predetermined rotation step and/or time. (20) is gradually rotated in one direction in seconds.

The path through which the solar panel 20 rotates is preferably set to be sufficiently exposed to the sun as much as possible in consideration of the amount of sunlight. If the solar panel 20 is rotated at a constant speed for a predetermined time using the rotating device 30 disposed on the upper portion of the bending part 40, the solar panel ( Compared to the case where 20) is stationary toward one side, the amount of solar power generated can be increased.

The micom drives and senses the rotation of the solar panel 20 step by step from the operation of the limit switch 60 that is turned on/off by a change in the uneven pattern according to the rotation of the rotation count plate 63. Here, the first step of the rotation of the solar panel 20 is that one cycle of the rotation count plate 63, that is, the limit switch 60 touches any one of the grooves included in the uneven pattern, and then touches the next groove. It can be defined by counting.

Particularly, the micom controls the driving motor 30d of the bending part 40 to set the number of rotation steps differently for each season to control the amount of rotation per day (rotation angle) for the solar panel 20 differently. Can. When considering the seasonal sunshine, it is desirable to perform the rotation control by setting the number of rotation stages the most for the summer in the four seasons (setting the most rotation) and the setting for the winter the least (setting the least rotation). Specifically, the micom sets the number of rotation steps of the rotation count plate 63 to 1-11 steps in spring/autumn, 0-12 steps in summer, and 2-10 steps in winter to perform rotation control. To this end, the data of the rotation step setting value is stored in the memory of the microcomputer.

In addition, the main controller communicates with each of the micom by wire and wireless to manage different solar panels 20 and rotating devices 30, so that the entire solar panels 20 are substantially in the same pattern. Control to rotate.

Additionally, the main controller detects the wind direction during rainy weather and performs control to rotate the solar panel 20 in a direction facing the raindrops. That is, by directly exposing the surface of the photovoltaic panel 20 to raindrops, fine dust or foreign substances accumulated on the surface of the photovoltaic panel 20 can be effectively removed.

On the other hand, the present invention can keep the trees around the pole 10 supporting the solar panel 20, so it is possible to construct an eco-friendly solar power generation facility while minimizing natural damage. Trees located around the pole 10 can also act as a windbreak forest, so the solar panel 20 can be installed more stably.

The solar panel 20 may be rotated at a predetermined time and speed by the rotating device 30 during operation of the single-axis-driven photovoltaic power generation system having an inclined structure to increase the amount of photovoltaic power generation.

The photovoltaic panel 20 is gradually rotated in a direction inclined with respect to the ground around the rotation axis A1 by the rotating device 30 so that the azimuth angle can be adjusted and the incident angle to the sun can be adjusted.

A rotating count plate 63 is fixed to a lower portion of the rotating gear 62 provided in the rotating device 30 to rotate integrally with the rotating gear 62, and a limit switch 60 is provided to the lower portion of the rotating count plate 63. By continuously maintaining contact, the uneven pattern of the rotating count plate 63 can be detected to detect the amount of rotation step by step. The micom controls the rotating device 30 based on the output signal of the limit switch 60 which is turned on/off by a change in the uneven pattern according to the rotation of the rotating count plate 63, thereby inclining the solar panel 20. It drives the rotation in the direction and the horizontal direction step by step and detects whether the solar panel 20 rotates in seconds without error and reflects it in the control operation.

That is, when maintenance or cleaning of a specific lighting unit 13a or CCTV camera 14a is required, the administrator may selectively lower only the lighting unit 13a or CCTV camera 14a to perform the operation. Alternatively, it is also possible that the lighting unit 13a and the CCTV camera 14a are elevated and controlled in groups. In this case, it is possible to perform control for collectively elevating a plurality of CCTV cameras 14a. In addition, if necessary, it is also possible to control all the lighting units 13a and the CCTV cameras 14a to be lifted together at once.

The elevating operation for the elevating type lighting module 13 and the elevating type camera module 14 may be individually performed by wired or wireless communication. When using wireless communication, Wi-Fi or LTE may be used as a wireless communication standard.

The photovoltaic panel 20 is installed on the top of the pole 10 to supply solar power to the elevated lighting module 13 and the elevated camera module 14. The elevating lighting module 13 and the elevating camera module 14 may be basically configured to receive power from a commercial power grid and receive emergency power from the solar panel 20 during a power failure.

Preferably, the microcomputer installed on one side of the pole 10 controls the operating time and speed of the drive motor of the rotating device 30 in conjunction with an illuminance sensor. The microcomputer recognizes that the day is darkened or brightened from the output value (illuminance value) of the illuminance sensor or the set time. For example, when the sun illuminance value exceeds a predetermined value, the microcomputer recognizes that the day is bright and operates the driving motor to gradually rotate the solar panel 20 in one direction for a predetermined time. The path through which the solar panel 20 rotates is preferably set to be sufficiently exposed to the sun as much as possible in consideration of the amount of sunlight. If the photovoltaic panel 20 is rotated at a constant speed for a predetermined time, the amount of photovoltaic power generated compared to the case where the photovoltaic panel 20 is stationary toward one side, even if a photovoltaic tracking device having a complicated structure is not used separately Can increase.

As illustrated in FIG. 12, the detection sensor 90 for the operation of the lighting unit 13a is installed on the outer wall 100 of the building at a position spaced apart from the pole 10. When a pedestrian approaching the detection sensor 90 is detected, the detection signal is wirelessly transmitted to the lighting control unit of the elevating-type lighting module 13 so that the lighting unit 13a is automatically turned on. As described above, since the detection sensor 90 is disposed at a position spaced apart from the pole 10, it is possible to detect an approach without error even if the pedestrian is on either side of the pole 10. Alternatively, the detection sensor 90 is a predetermined ring-shaped mount detection sensor 90 is fixed around the outer surface of the pole 10, as shown in Figure 18 when the pedestrian is detected when the detection signal is elevated Wireless transmission to the lighting module (13). At this time, Wi-Fi, LTE, Bluetooth, etc. may be used as the wireless communication standard.

The lighting control unit (not shown) embedded in the elevation lighting module 13 performs control to selectively turn on the lighting unit 13a when the detection sensor 90 outputs a detection signal. Preferably, the lighting control unit of the elevating-type lighting module 13 may perform an automatic on/off control that turns on the lighting unit 13a when a pedestrian approaches or moves and turns off automatically after a certain period of time. At this time, the on/off time may be set by receiving input through wired or wireless communication from the administrator.

Additionally, the lighting control unit may automatically output an alarm sound, a warning message, or music when a pedestrian approach is detected.
