Description

Solar power generator

The present invention relates to a solar power generation device.

First, the solar system 10 of Patent Document 1 has a solar cell panel 12 to which a large number of solar cells 11 are attached, a position sensor unit 13 that receives sunlight to detect the position of the sun, and a wind force that detects wind force. A total of 14 and a pair of winches 15 that rotate the solar cell panel 12 so that the cell surface of the solar cell 11 faces the sun based on the detection signal from the position sensor unit 13. The central portion of the winch 15 is supported by a double-sided drum 17a provided at the upper end of the suspension member 17 extending above the solar cell panel 12, and both ends thereof are the solar cell panel. The left and right ends of 12 are connected to each other.

In this solar system 10, since the solar cell panel 12 can swing in a seesaw manner, it is possible to increase the amount of power generation per day, but there are the following drawbacks.
(A) Since the solar cell panel 12 is arranged via the pair of bearings 16a provided on the top of the roof a and the rotating shaft 12a penetrating the bearings, the mounting of the solar cell panel 12 is very troublesome. (B) Since a pair of suspending members (long poles) 17 need to be fixedly erected on the upper surface of a base (storage box) 16 for storing a pair of winches 15, the winch 15 is set to the sun. It cannot be easily attached to the battery panel 12. Therefore, it takes time to assemble. (C) Since the solar cell panel 12 is suspended by the suspension member 17 and the pair of winches 15, the solar cell panel 12 needs to be held in a horizontal state during strong wind. (D) A plurality of solar cell panels 12 cannot be connected in a horizontal series. Therefore, in order to rotate the plurality of solar cell panels 12, each drive source is required (reference numeral is that of Patent Document 1).

Next, in the device of Patent Document 2, a belt pulley for transmitting the power of a drive source is rotatably supported by a center portion of a fixed base, and a pair of support members are vertically fixed to the belt pulley. A pair of short tubular bearings are fixed to the upper end of the support member, and a horizontal shaft fixed to the center of a solar panel mount is fitted into the pair of short tubular bearings.
In this device, the mount for the solar panel can be displaced in the horizontal direction, so that the amount of power generation can be increased. However, since the horizontal shaft has to be fitted and inserted in the short tubular bearing, there is the same problem as in Patent Document 1. Further, since this device does not swing the mount for the solar panel in a seesaw type, the amount of power generation cannot be sufficiently increased.

Patent Document 1: Japanese Patent No. 3195783 Patent Document 2: Japanese Patent Laid-Open No. 57-188965

The main problem of the present invention is that the device can be manufactured at low cost and that the device can be easily assembled in the field in a short time. Also, the solar panel is not damaged by strong wind. Furthermore, it is possible to increase the amount of power generation per day. A secondary object of the invention is to ensure that the chain engages the drive and driven sprockets in a non-slip manner when the towing member is a chain. In addition, it is possible to rotate the solar panels of a plurality of photovoltaic power generators with one drive source.

The solar power generation device includes a base portion installed on a flat surface, a leg-shaped support portion extending upward from a substantially central portion of the base portion, and a fixedly provided upper end portion of the leg-shaped support portion, and A solar panel pedestal having a horizontal fitting portion that opens upward, and a rotating portion that is fixedly projectingly provided in a substantially central portion of the back surface thereof and that is freely fitted to the horizontal fitting portion. And a drive source which is provided on the pedestal and whose start and stop are controlled by a control signal of a control unit, and one end of which is attached to a first fixture on one side of the solar panel. And is disposed below the solar panel with the other end attached to the second fixture on the other side of the solar panel, and the middle part thereof engages with the drive transmission part on the drive source side. One indexing member and the pedestal, , Characterized in that it comprises a plurality of detecting means for detecting one of the inclined posture and the other inclined posture of the solar panel, respectively.

In the above configuration, an intermediary rotating body is provided on the base portion via a support plate, and the intermediary rotating body engages with a midway portion of the index member and changes a direction of the index member. To do. Further, the rotating portion is a long rod member, and at least the first solar panel and the second solar panel apart from the first solar panel are provided on the upper end portion of the long rod member. It is characterized by

Further, the elongated index member is a chain, and the chain comprises an upper driven sprocket (26A) fixedly provided on the horizontal shaft portion of the rotating portion, and a pair of left and right driven sprockets as a reference. A pair of left and right driven sprocket (26, 26) and a pair of left and right attachments for engaging the drive sprocket (18) of the drive source installed on the support base (17A) of the base between the lower driven sprocket (26, 26). It is characterized in that it is connected to the tools (23, 24). In addition, a mounting plate that can be integrally connected to a solar panel of another solar power generation device is fixed to a protruding end portion of the horizontal shaft portion of the rotating portion.

”Here,“ turning ”means swinging the solar panel to a predetermined angle in a seesaw fashion. The "upper end portion of the leg-shaped support portion" also includes a portion near the upper end portion or the upper surface. Further, here, the “central portion” also includes a portion near the central portion.

The main components are a pedestal having a horizontal fitting portion at the upper end, a solar panel having a rotating portion that freely fits in the horizontal fitting portion, and a traction member arranged below the solar panel. And a control unit for controlling the rotation direction of the drive source, which is provided on the base portion of the pedestal and applies power to the pulling member, so that the device can be manufactured at low cost.

Also, the solar panel can be freely placed on the horizontal fitting part of the pedestal and the traction member can be appropriately arranged, so that the device can be easily and quickly assembled on site. In addition, since both ends of the solar panel are connected and supported by both ends of the pulling member, the solar panel does not “rattle” due to strong wind, so it is not easily damaged. Further, since the tilted posture of the solar panel can be changed within the range of the required angle, the amount of power generation per day can be increased.

Note that if other constituents are added to the independent claim, for example, when the traction member is a chain, the chain is securely engaged with the drive sprocket and the driven sprocket so as not to slip. Also, when the intermediary rotating body is integrally provided on the horizontal shaft of the horizontal fitting portion of one solar panel, by connecting to the horizontal shaft of the horizontal fitting portion of another solar panel via the mounting plate, It is possible to rotate the solar panels of a plurality of photovoltaic power generators with one drive source.

1 to 10 are explanatory views showing a solar power generation system X according to the first embodiment of the present invention. First, in order to understand the basic principle of the present invention, an explanation will be given with an example in which each of the cradle 1 and the solar panel 11 is one. Here, with reference to FIG. 2, the sides on which the

short rods

2a, 2a are present are referred to as left and right. Similarly, with reference to FIG. 2, the side where the

long rods

2b and 2b exist is referred to as the front and rear.

By the way, reference numeral 1 is a frame-structured pedestal installed on a flat surface F such as a mountain area, a site, a rooftop, a ship, and a turntable. As shown in FIG. 2, the pedestal 1 includes a rectangular frame-shaped base portion 2 placed on the flat surface F in a substantially horizontal state, and a pair of left and right

short rods

2a, 2a forming the base portion 2. A pair of left and right leg-shaped

support portions

3, 3 whose lower end portions are fixed to the central portion via mounting fittings 3a, and a cross section in which both left and right end portions are fixed to the upper end portions of these leg-shaped

support portions

3, 3. It has a V-block-shaped (embodiment) horizontal fitting portion 4 (see FIG. 3).

In the embodiment, further, the pedestal 1 is connected to each end of the horizontal fitting portion 4 and each end of the pair of front and rear

long rods

2b and 2b orthogonal to the pair of

short rods

2a and 2a. The slanted receiving part 5 for the solar panel of the book, and the horizontal connecting rods 6 fixed to the substantially central portions of the

long rods

2b, 2b, respectively, are provided at the approximately central portion of one side wall of the connecting rod 6. Is connected to a substantially rectangular mounting base 7.

≪Additional remarks about cradle 1. The pedestal 1 has a frame structure using fixing means such as welding and a fixing tool so as to be manufactured at low cost. However, the base portion 2, the leg-shaped support portion 3, the inclined receiving portion 5 and the like may have a wide plate shape. In this case, a guide hole or a notch for a pulling member, which will be described later, is formed at an appropriate position of the inclined receiving portion 5. Further, the lower end portion of the leg-shaped support portion 3 is fixed to the short rod 2a via the fitting 3a, but may be welded.

One horizontal fitting part 4 is provided on the pair of left and right leg-shaped supporting parts 3, but a plurality of horizontal fitting parts 4 may be provided. For example, the pair of horizontal fitting portions 4 may be provided separately from each other so as to face the left and right leg-shaped support portions 3, respectively.

Further, the horizontal fitting portion is a wedge-shaped fitting groove that opens upward in the embodiment, but has a shape in which the horizontal shaft-shaped rotating portion 12 of the solar panel described later is detachably fitted. If it exists, for example, it may have a recessed cross section, a semicircular cross section, a U-shaped cross section, a Y-shaped cross section, or an inverted trapezoidal cross section.

The material of the horizontal fitting portion 4 may be either metal or synthetic resin as long as it can support the solar panel. The length of the leg-shaped support portion 3 is preferably set within the range of 20 to 45 degrees, for example, depending on the region where the inclination angle of the solar panel is inclined.

Next, the solar panel 11 will be described. Although a detailed illustration of the solar panel 11 is omitted, the solar panel 11 includes, for example, a grid-shaped pedestal 11a, a large number of solar cells 11b arranged on the upper surface of the pedestal 11a in the left / right and front / back directions, and the pedestal 11a as appropriate. And an output terminal 11c provided at the location.
In the embodiment, the solar panel 11 preferably has a rectangular shape, but the shape is not limited and may be, for example, a track shape in plan view, a square shape, an elliptical shape, or the like.

Thus, as shown in FIG. 1, the solar panel 11 of the present invention is fixedly provided on the rear surface of the pedestal 11a substantially in the center thereof and is detachably attached to the horizontal fitting portion 4 of the cradle 1 described above. The rotating portion 12 having the horizontal shaft portion that fits in the above is provided in a single number (in the present embodiment) or in a plurality apart from each other (when there are a plurality of horizontal fitting portions 4).

By the way, since the solar panel 11 is required to swing the left and right ends in a seesaw manner by a predetermined amount with reference to FIG. 1, the rotating portion 12 has a length that protrudes a required amount downward from the back surface of the solar panel 11. It is composed of a plate-like hanging piece 12a and a horizontal shaft 12b having an end face substantially circular shape integrally provided at the lower end portion of the hanging piece 12a. The horizontal shaft 12b may be solid, hollow, or pipe-shaped. The diameter of the horizontal shaft 12b is appropriately set in consideration of the width of the inclined or vertical facing receiving

surfaces

4a, 4a forming the horizontal fitting portion 4.

Next, the control unit 15, the driving source 16 and the like will be described with reference to FIGS. 4 and 5. The control unit 15, the drive source 16, the speed reducer 17, and the drive transmission unit 18 are arranged in parallel on the upper surface of the base unit 2 of the pedestal 1 or the mounting base 7. In the embodiment, the drive source 16 is a geared motor. The drive transmission portion 18 is a sprocket that is continuously engaged with the engaging portion of the pulling member 19.

Therefore, the control unit 15 acquires the detection signals respectively detected by the first detection unit 21 and the second detection unit 22 as shown in FIG. 8 via the input unit 15a. The control unit 15 has an arithmetic processing unit, a storage unit that stores a main program, a work program, and the like, a clock unit, and a determination unit, and outputs the determination result to the drive source 16 via the output unit 15b. Since each detection signal of the first detection means 21 and the second detection means 22 is a "stop signal" for the control unit 15 to stop the drive source 16, the control unit 15 determines a predetermined value based on the count information from the clock unit. After a lapse of time, the rotation direction of the drive source 16 is controlled to "from forward rotation to reverse rotation" or "from reverse rotation to forward rotation". Therefore, the drive source 16 is controlled by the control signal of the control unit 15 and its start and stop.

Next, the plurality of detection means 21 and 22 will be described with reference to FIGS. 1 and 6. Here, the detection means attached to one sidewall of the lower end portion of the left side inclined receiving portion 5 is referred to as "first detecting means 21", while the lower end portion of the right side inclined receiving portion 5 is referred to in FIG. The detection means attached to one side wall is referred to as "second detection means 22". As the detecting

means

21 and 22, limit switches having

sensing levers

21a and 22a for mechanically detecting a stop signal are adopted. Note that other detection means (for example, an optical sensor, a magnet switch, etc.) may be used instead of the limit switch.

Next, with reference to FIGS. 1 and 7, the manner of attaching the pulling member 19 such as a wire or a chain will be described. As the elongated index member 19, a chain that is securely engaged with the circumferential engagement portion of the drive transmission portion (drive sprocket) 18 is adopted.
Then, one end of the chain 19 (the left side of the drawing with reference to FIG. 1) is attached to the ring-shaped first fixture 23 on one side of the solar panel 11, while the other end (the right side of the drawing) is attached. It is attached to a second ring-shaped fixture 24 on the other side of the solar panel, and its midway portion engages with the drive sprocket 18.

By the way, the secondary subject of the present invention is to securely engage the engaging portion of the chain 19 with the drive transmission portion 18 and the intermediary rotating body 26, and / or to easily adjust the tension of the chain 19. That is what you can do.

First, in order to securely engage the chain 19 with the respective engaging portions of the drive transmission portion (drive sprocket) 18 and the intermediary rotating body (following sprocket) 26, one end of the solar panel 11 is opposed. The support plate 25 is fixed to an appropriate portion, and the driven sprocket as the intermediary rotating body 26 is pivotally supported on the support plate 25. Further, the position of the drive transmission portion 18 is brought close to the second attachment 24 at the other end of the solar panel 11.

The left and right midway portions of the chain 19 are engaged with the drive transmission portion (drive sprocket 18) of the drive source 16 near the second attachment 24 and the intermediary rotating body (driven sprocket) 26 from below. ..

Therefore, the drive sprocket 18 and the driven sprocket 26 play a role of changing the direction of the chain 19 obliquely upward, so that the chain 19 can be securely engaged with the drive sprocket 18 and the driven sprocket 26 so as not to slip.
Next, when the tension of the chain 19 is easily adjusted, a pair of

turnbuckles

27 and 28 are attached to one end or both ends (embodiment) of the chain 19, respectively. Then, hook

portions

29 and 30 are provided on the protruding end portions of the upper and lower screw rods that form the

turnbuckles

27 and 28, respectively.

Therefore, in the embodiment, the intermediary rotating body 26 is provided on the base portion 2 of the pedestal 1 via the support plate 25, and the intermediary rotating body 26 engages with the middle portion of the index member 19 and the index member 19 is provided. Change the direction of.

Next, the left and right ends are attached to the left and right fixtures 23 of the solar panel 11 with the pulling member 19 engaged with the respective engaging portions of the drive transmission portion (drive sprocket) 18 and the intermediary rotating body (driven sprocket) 26. , 24 are engaged with each other. Therefore, at the work site, the assembly is very simple, and the solar power generation device X can be installed on the flat surface F in a short time.

FIG. 9 is a schematic explanatory diagram of a state where the solar panel 11 is tilted in one direction. On the other hand, FIG. 10 is a schematic explanatory view of a state in which the solar panel 11 is tilted in the other direction, for example, at noon (12:00) after a predetermined time has elapsed. When returning from the state of FIG. 10 to the state of FIG. 9, depending on the program recorded in the storage unit of the control unit 15, the clock unit of the control unit 15 counts based on the stop signal of the second detection unit 22. After a predetermined time (for example, 6 hours) after that, the drive source (geared motor) 16 is reversely rotated.

With the above configuration, the solar panel 11 can be easily mounted on the pedestal 1, and the solar panel 11 can be swung in a seesaw manner via the tow portion arranged below the solar panel 11. The device can be manufactured at low cost because the longer the horizontal shaft-shaped rotating portion 12 is, the more solar panels 11 can be attached to the upper end portion of the rotating portion 12. The amount of power generation per day can be increased.

Although not particularly shown, in the first embodiment, when the sun rises or falls with the installation position of the photovoltaic power generator X as a reference, the cradle 1 is appropriately adjusted according to the season. It is preferable to rotate in the horizontal direction to a certain angle. In such a case, a turntable (not shown) is provided at the lower end of the pedestal 1, and a transmission gear portion is provided on the outer peripheral portion of the turntable. On the other hand, a gear box is provided near the turntable, The drive gear of the box is meshed with the transmission gear portion. Then, the drive gear on the drive source side can be rotated manually or electrically in response to a change in the position of the sun.

Further, in the embodiment, the control unit 15 and the drive source 16 use the power source obtained from the solar panel 11. Therefore, since the electricity obtained from the solar panel 11 is used as a power source, the solar power generation device X can be installed in a desired place such as a mountain area, a river area, or a field.
