Description

Solar Power Device with Seasonal and Daily Tracking {SOLAR POWER DEVICE WITH SEASONAL AND DAILY TRACKING}

The present invention relates to a solar power generation device capable of seasonal and daily tracking.

In recent years, as depletion of fossil energy and environmental problems have emerged, renewable energy industries such as solar and wind power generation are growing. Photovoltaic power generation converts the light energy of sunlight incident on a solar panel into electrical energy. The efficiency of solar power generation is greatly affected by the angle and amount of sunlight incident on a solar panel. When the angle of incidence between the solar panel and sunlight is at right angles, it is possible to generate power with maximum efficiency.

Accordingly, a tracking device capable of tracking an elevation angle and an azimuth angle of the solar panel along the trajectory of the sun is used in the photovoltaic device. Such a tracking device is effective in increasing solar power generation efficiency by controlling the rotation and inclination angle of the solar panel according to the movement of the sun, but it is difficult to apply due to the high cost of sensor parts for detecting the position and movement of the sun. cases are occurring. In addition, in the case of such a power method, power consumption is generated to operate the device, and there may be cases in which power generation efficiency is not substantially improved compared to stationary photovoltaic power generation. In some cases, complex algorithms and mechanical structures are involved, resulting in frequent breakdowns or difficult management problems during use.

Therefore, there is a demand for a new type of photovoltaic power generation device that considers both power generation efficiency and cost.

Embodiments of the present invention are intended to provide a solar power generation device capable of seasonal and daily tracking.

A central angle tube disposed in the vertical direction; and a back frame intersecting the central square tube at the center of the panel and disposed in the left and right directions, wherein the angle adjusting unit includes a cylinder fixing part protruding from one side of the back frame, and one side of the central square tube. A pair of cylinder brackets protruding apart from each other and having a pair of cylinder fixing holes formed at corresponding positions so as to penetrate the pair of cylinder brackets; and a seasonal cylinder having one side connected to the cylinder fixing part and the other side connected to the cylinder bracket by a fastening member penetrating the cylinder fixing hole and capable of adjusting the elevation angle of the panel. may be provided.

The photovoltaic device according to embodiments of the present invention can perform daily tracking and seasonal tracking, and thus can have higher power efficiency than a fixed photovoltaic device. Daily tracking is automatically controlled, but seasonal tracking can be manually operated by a worker, thereby reducing failure factors by minimizing power devices. Due to the drainage structure formed on the bag frame, drainage can be smoothly performed even in strong typhoons and rainwater inflow, and water can be prevented from entering the rotation control unit. In addition, the foldable photovoltaic device can mitigate the impact applied when folding through the configuration of the locking control unit. When the panel is folded by the configuration of the panel protection unit, the panel is automatically covered with a protection pad, thereby protecting the panel from external influences when the solar power generation device is moved.

One side of the angle adjusting unit 130 is connected to the central angle tube 112a and the other side is connected to the back frame 114 to serve to adjust the elevation angle of the panel P according to the change of the season. The angle adjusting unit 130 may include a seasonal cylinder 131, a cylinder fixing unit 132 and a cylinder bracket 133. Adjustment of the elevation angle of the panel P according to the season may be achieved through manipulation of the season cylinder 131 of the angle adjusting unit 130 or direct manipulation of the panel P.

Alternatively, when the panel P is directly manipulated, the seasonal cylinder 131 is adjusted correspondingly to this, so that the elevation angle of the panel P can be adjusted.

At this time, the elevation angle may refer to an angle between a direction perpendicular to the plane of the panel P and the bottom surface. It is possible to adjust the elevation angle of the panel P by setting the elevation angle of the panel P high in summer, low in winter, and midway between summer and winter in spring and autumn.

The cylinder fixing part 132 may be illustrated in an approximate 'c' shape. Holes are formed at corresponding positions on both side surfaces of the cylinder fixing part 132, and one side of the seasonal cylinder 131 may be penetrated.

The seasonal cylinder 131 and the cylinder bracket 133 may be penetrated and fixed by a fastening member (not shown) penetrating the cylinder fixing hole 133a and the seasonal cylinder 131 .

Therefore, the season cylinder 131 is connected through the cylinder fixing part 132 and the cylinder bracket 133 to support the panel P at a certain angle according to the season. When adjusting the angle of the panel P in response to the change of the season, the angle of the panel P can be adjusted to a predetermined angle by a worker manipulating the seasonal cylinder 131 . Alternatively, seasonal adjustment may be possible by directly manipulating the panel P. The season cylinder 131 is adjusted to correspond to the elevation angle adjustment of the panel P, so that the panel P can be tracked by season.

The operation of the photovoltaic device 100 as described above is as follows. Daily tracking of the photovoltaic device 100 is possible due to the rotation control unit 120 to which the swing drive is applied. By using the power device included in the rotation control unit 120, the panel P rotates without a separate manipulation, and the photovoltaic device 100 can generate power while tracking it daily.

In addition, seasonal tracking may be possible through the angle adjusting unit 130 . The angle adjusting unit 130 may adjust the elevation angle of the panel P according to the change of the season. In detail, when changing the altitude angle of the panel P, the operator can operate the seasonal cylinder 131. By adjusting the seasonal cylinder 131 to change the altitude angle of the panel P to a desired angle, it is possible to track the photovoltaic device 100 by season in response to the change of the season. Alternatively, seasonal adjustment may be possible by directly manipulating the panel P. When the altitude angle is adjusted for each season through manipulation of the panel P, the season cylinder 131 is adjusted to correspond thereto, so that tracking for each season is possible.

In addition, when rainwater such as a typhoon or precipitation flows in, it is possible to prevent foreign substances from entering the rotation control unit 120 by the drainage structure of the back frame 114 . Unlike other configurations, the rotation control unit 120 is applied with a swing drive including a power device. Therefore, since the continuous inflow of foreign substances such as rainwater may cause failure and malfunction, a configuration for preventing this may be required. Therefore, by applying the first modification and the second modification of the drainage structure of the bag frame 114, it is possible to prevent foreign substances from entering the rotation control unit 120.

In the case of the drainage structure of the first modified example of the bag frame 114, when rainwater such as typhoon and precipitation enters, rainwater moves to the lower plate 114-2 through the drainage hole 114a disposed in the upper plate 114-1. It can be. Rainwater moved to the lower plate 114-2 may be drained to the outside along the inclined portion 114b formed to incline inwardly and outwardly with respect to the center of the lower plate 114-2. At this time, a rib for reinforcing is disposed at the center of the lower plate 114-2 above the rotation control unit 120 to prevent rainwater from flowing toward the rotation control unit 120. That is, rainwater may pass through the drain hole 114a of the upper plate 114-1, move to the inclined portion 114b of the lower plate 114-2, and be drained to the outside.

Meanwhile, in the case of the drainage structure of the second modified example of the bag frame 114, when rainwater such as typhoon and precipitation enters, rainwater can be moved downward through the drainage hole 114d disposed in the upper plate 114-3. . When rainwater moves to the inclined portion 114e disposed between the upper plate 114-3 and the lower plate 114-4, it is disposed from one end of the upper plate 114-3 to one end of the lower plate 114-4. Rainwater is drained to the side along the inclined portion 114e. At this time, since the inclined portion 114e is disposed to be inclined from one end of the upper plate 114-3 to one end of the lower plate 114-4, it is possible to prevent drainage of rainwater toward the center of the back frame 114. . In addition, reinforcing ribs extending from the bag frame 114 are disposed at the center to effectively prevent rainwater from entering the rotation control unit 120 . That is, rainwater may pass through the drainage hole 114d of the upper plate 114-3 and move to the inclined portion 114e of the lower plate 114-4 to be drained to the outside in a lateral direction.

In particular, it is mobile for military use and easy to use, and has the advantage of being easy to prepare for natural disasters such as typhoons.

In this embodiment, the panel frame 218 is disposed on both sides of the panel P, and the lock control unit 240 may be formed on the panel frame 218. Therefore, when the panel P is folded, the impact of the panel P can be alleviated by the lock control unit 240 and the panel P can be fixed and supported in a locked state. Looking at the detailed structure, a cylindrical protruding member 241 formed with a concave portion may be provided on the upper part of the panel frame 218 disposed on both sides of the upper panel P1. An insertion part 242 may be provided at the lower part of the panel frame 218 disposed on both sides of the corresponding lower panel P2 .

In addition, the second elastic member 245 may be disposed on the innermost side of the insertion part 242 in a shape corresponding to the end of the protruding member 241 .

Looking at the operation process in detail, when the panel P is converted to a folded state based on the hinge part 216, the protruding member 241 starts to be inserted into the insertion part 242, and the spring inside the insertion part 242 (243) is pushed and contracted by the protruding member (241). When the protruding member 241 is continuously inserted while the spring 243 is contracted, and the spring 243 is positioned up to the concave portion of the protruding member 241, the contracted spring 243 is relaxed. At this time, the first elastic member 244 disposed at the end of the spring 243 supports the concave portion of the protruding member 241 and supports and fixes the protruding member 241 . Also, in this process, the end of the protruding member 241 is supported in contact with the second elastic member 245, and the impact is mitigated by the first elastic member 244 and the second elastic member 245, and the panel P It can be safely switched to this folded state.

When the panel P is converted from a folded state to an open state, the protruding member 241 can be removed by pulling a handle (not shown) disposed outside the panel frame 218 to contract the spring 243. .

In addition, when the panel P is moved in a folded state, the panel P can be safely protected by including the panel protection unit 250 capable of protecting the panel P. A first wire 251 is fixed to the top of the pair of panel frames 218 of the upper panel P1, and a second wire 252 is attached to the pair of panel frames 218 of the lower panel P2. It is connected to the protection pad 253 disposed on and may be arranged in a donut shape. The first wire 251 extends and is connected to the second wire 252, and a weight 251a may be disposed at an end of the first wire 251. In addition, a plurality of rolling parts 218b may be disposed at an edge of the panel frame 218 of the lower panel P2, and a second wire 252 may be disposed at the rolling part 218b. A support jaw 218a may be provided at the lower end of the lower panel P2.

Referring to FIG. 7, the operation process will be described in detail. In the state of (a) of FIG. 7 in which the panel P is not folded, when the panel P is converted to the folded state, the first wire ( The first wire 251 is moved toward the ground by the weight 251a connected to the end of the first wire 251. The second wire 252 connected to the first wire 251 also rotates around the panel frame 218 connected to the lower panel P2 without departing in the other direction by the rolling part 218b. At this time, the second wire 252 and both sides are connected and the protective pad 253 disposed on the rear surface of the lower panel P2 rotates through the spacer 217 and can be moved to the upper surface of the lower panel P2. .

As shown in (c) of FIG. 7 , when the panel P is completely folded, the protection pad 253 contacts the support protrusion 218a and the protection pad 253 does not move any more and is between the panels P. will be located in Therefore, the protective pad 253 may serve to protect each panel P during movement between the upper panel P1 and the lower panel P2. When the panel P is converted to the open state, the protective pad 253 may move to the rear surface of the lower panel P2 and be disposed in the original state.

As described above, the photovoltaic device according to embodiments of the present invention can perform daily tracking and seasonal tracking, and thus can have higher power efficiency than a fixed photovoltaic device. At this time, if a device that uses a lot of power or a device with complex mechanical components is added to the photovoltaic device, power generation efficiency may be lowered or difficulties in management due to failure may occur. Therefore, daily tracking is automatically controlled, but seasonal tracking can be manually operated by an operator, thereby reducing failure factors by minimizing power devices. Seasonal tracking is possible by adjusting the angle of the panel for each season as needed by the operator.

In addition, the photovoltaic device according to embodiments of the present invention can drain smoothly even in strong typhoons and inflow of rainwater by the drainage structure formed on the back frame, and can prevent water from entering the rotation control unit. . The rotation control unit disposed on the rear side of the panel rotates the panel by a motor connected to the swing drive for daily tracking. At this time, when water is introduced into the motor and the drive due to typhoon or rainwater, it may cause a failure. In the case of solar panels, when repairs are required due to frequent failures, not only power generation efficiency is lowered, but also there is a problem in that demand for solar panels may be lowered due to difficulties in management. Therefore, by forming a structure such as a drain hole and an inclined portion so that water can be drained away from the rotation control unit in the back frame, it is possible to prevent the rotation control unit from malfunctioning due to water.

In addition, the foldable photovoltaic device can mitigate the impact applied when folded through the configuration of the locking control unit. Among the photovoltaic devices of this embodiment, since the foldable photovoltaic device is a heavy object, it is necessary to alleviate the impact when folded. Therefore, while the protruding member formed with a plurality of curves is inserted into the insertion portion including the spring and the elastic member, the panel is not closed at once, but stops and closes as much as the number of the curved portions, and shock can be alleviated. In addition, when the photovoltaic device is moved in a folded state, it may also play a role in preventing the panel from being opened or moved. Since the spring and the elastic member support the protruding member in the folded state of the panel, it is possible to prevent the panel from being opened or moved when the panel is moved using a vehicle or crane.

In addition, in the case of a foldable solar power generation device, when the panel is folded by the configuration of the panel protection unit, a protective pad is automatically covered on the panel, thereby protecting the panel from external influences when the solar power generation device is moved. When the panels are moved in a folded state, since the panels come close to each other, there is a need to prevent damage to the panels. At this time, the panel can be safely protected and moved by the panel frame having a step with the panel and the panel protection unit disposed on the upper surface of the panel. When the panel is folded, the protective pad connected to the wire moves from the back side of the panel to the top side of the panel to safely protect the panel. Accordingly, when the panel is moved, damage to the panel can be prevented, and the photovoltaic device can be easily moved.

The present invention can be variously modified and changed by the like, and this will also be said to be included within the scope of the present invention.
