Description

[Technical field]

[0001] The present invention relates to a solar power generator capable of preventing theft and tampering with a solar cell module, and a pole-type solar power generation device using the same. [Background technology]

[0002] Conventionally, there is known a pole with a solar cell, in which a solar cell module is attached substantially vertically to the peripheral wall of the pole body and which has the function of generating electricity by utilizing at least scattered light from sunlight among scattered light and direct light (see Patent Document 1).

[0003] Such a pole with solar cells requires a small installation area, so that the installation location is not limited, and it is also excellent in terms of scenery. However, an expensive solar cell module is installed on the peripheral wall of the pole body, and this solar cell module can be a target for theft and vandalism. If the solar cell module is firmly attached to prevent such theft, the removal work of the solar cell module may become complicated during regular maintenance or replacement due to failure. Furthermore, there are other solar cell modules that use a curved solar cell module to improve design and power generation efficiency, but the installation structure of such a curved solar cell module is more complicated, so it is difficult to easily remove the solar cell module during regular maintenance while preventing theft.

[0004] [Patent Document 1] Japanese Patent Application Publication No. 10-233236 Summary of the Invention [Problem to be solved by the invention]

[0005] In view of the above-mentioned situation, the present invention aims to solve the problem by providing a solar power generator and a pole-type solar power generation device that can prevent theft and vandalism of the solar cell module, and that allows the solar cell module to be easily removed for regular maintenance or replacement. [Means for solving the problem]

[0006] The solar generator of the present invention comprises a main body having at least a curved area for mounting a solar cell module, the solar cell module being flexible and mounted in the mounting area of ​​the main body, a pressing member covering the end of the solar cell module which can be changed by sliding it relative to the main body between a locked state in which it cannot be attached or detached and an unlocked state in which it can be attached or detached, an operating unit which operates the sliding movement of the pressing member, and a protective cover which covers at least the operating unit in the locked state.

[0007] According to this configuration, when the pressing member is in the locked state, the operating part is protected by a protective cover that covers the operating part, making it impossible for persons other than those involved to easily remove the solar cell module, thereby preventing theft or tampering with the solar cell module.

[0008] In addition, the pressing member may have an engaging portion and the main body portion may have an engaged portion that engages with the engaging portion, and the pressing member may slide relative to the main body portion, and the engaging portion may engage with the engaged portion, thereby achieving the locked state.

[0009] According to this configuration, the pressing member can be put into the locked state by sliding the pressing member with a simple configuration.

[0010] Furthermore, an inclined surface may be formed on at least one of the engaging portion or the engaged portion, and the inclined surface may bring the pressing member closer to the main body portion as the pressing member slides in the direction toward the locked state.

[0011] According to this configuration, the pressing member and the main body portion can be brought closer together by sliding the pressing member, and the pressing member can be easily and firmly fixed to the main body portion, thereby firmly holding the solar cell module positioned between them.

[0012] Furthermore, the pressing members may be provided at the ends of two opposing sides of the solar cell module.

[0013] According to this configuration, by providing the solar cell module on two opposing edge portions, the solar cell module can be fixed more firmly, and the risk of theft, etc. can be further reduced.

[0014] In addition, the device may further include a plate-shaped member between the pressing member and the solar cell module, the plate-shaped member exerting an elastic force in a direction separating the pressing member and the solar cell module from each other when the pressing member is in a locked state.

[0015] According to this configuration, the solar cell module is pressed against the main body portion by the elastic force of the plate-like member in the locked state, thereby making it possible to fix the solar cell module more firmly.

[0016] Furthermore, the operating portion may be disposed on one end side of the pressing member, and a fastening member for fixing the pressing member so as to be unable to slide may be provided on the other end side.

[0017] According to this configuration, the retaining member provided on the opposite side to the operating portion can prevent the pressing member from sliding, so that a higher anti-theft effect can be achieved with a simple configuration.

[0018] The present invention may also be a pole-type solar power generation device including the above solar power generator, in which the operating part is disposed at the top of the pressing part in an installed state.

[0019] According to this configuration, the operation unit is provided at a high position, which further improves the anti-theft effect. Effect of the Invention

[0020] The solar power generator and the pole-type solar power generation device solar cell configured as described above can prevent theft and vandalism of the solar cell module, and can easily remove the solar cell module for regular maintenance or replacement.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0022] Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings, but the present invention is not limited to the form shown in the accompanying drawings and includes all embodiments that satisfy the requirements described in the claims. Figures 1 to 5 show the configuration of a pole-type solar power generation device 1 as an example of an embodiment of the present invention.

[0023] As shown in Figures 1 and 2, a pole-type solar power generation device 1 according to a first embodiment of the present invention includes a solar power generator 2. This solar power generator 2 includes a main body 4 having at least a portion of a curved surface in the area for mounting a solar cell module 3, a flexible solar cell module 3 mounted in the mounting area of ​​the main body 4, a pressing member 5 covering the end of the solar cell module 3, which can be changed between a locked state in which it cannot be attached or detached and an unlocked state in which it can be attached or detached by sliding it relative to the main body 4, an operating unit 6 for operating the sliding movement of the pressing member 5, and a protective cover 7 for covering at least the operating unit 6 in the locked state.

[0024] Here, with regard to the pole-type solar power generation device 1, the term "pole type" includes a single cylindrical one that is erected almost vertically as shown in the figure, and also broadly includes polygonal or elliptical pillars such as square pillars, two or more connected pillars instead of one, ones with a slight erection angle adjusted according to the terrain or use, and ones that can be folded, extended, or stored underground, etc. Accessories such as lights are provided on the top of the pole-type solar power generation device 1, and a battery that stores the power generated by the solar cell module 3, a power controller, etc. are housed inside.

[0025] The solar cell module 3 is a flexible rectangular sheet having a power generation area on the outer surface side that generates power from sunlight, and is attached so as to be wrapped around the outer peripheral surface of the main body 4. Two solar cell modules 3, 3 are attached to the main body 4, and each of the left and right ends is fixed to the main body 4 by pressing the left and right ends with a pressing member 5 and a plate-shaped member 11. At this time, one pressing member 5 and one plate-shaped member 11 are provided to cover the sides of the two adjacent solar cell modules 3, so two pressing members 5 and two plate-shaped members 11 are used for each of the two solar cell modules 3, 3, and the two solar cell modules 3, 3 are attached to the main body 4. In addition, the solar cell module 3 has a non-power generation area formed on the periphery that does not generate power, and this non-power generation area is covered by the pressing member 5 and the plate-shaped member 11. Therefore, although a part of the solar cell module is covered by the pressing member 5 and the plate-shaped member 11, the power generation efficiency does not decrease, and there is no problem such as damage to the power generation area of ​​the solar cell module 3. Even if not configured as described above, if part or all of the pressing member 5 or the plate-like member 11 are made transparent, it is possible to configure the solar cell module 3 without reducing the power generation efficiency even when it covers the solar cell module 3. Furthermore, the solar cell module 3 refers to any device that converts light energy such as sunlight into electrical energy, regardless of its mechanism or method, and includes all silicon-based, compound-based, organic-based, perovskite-type, and the like.

[0026] The main body 4 is formed in a generally cylindrical shape, with the solar cell module 3 wrapped around its outer periphery. Accessories such as lights are provided on the upper side of the main body 4, and legs are provided on the lower side, forming a pole-type solar power generation device 1, which is an example of a stand-alone device. As described above, the solar cell module 3 is fixed to the main body 4 using the pressing member 5 and the plate-like member 11.

[0027] The pressing member 5 is a long and narrow strip-shaped member made of metal, and an operating section 6 is attached to the upper end of the pressing member 5, and a plurality of engagement sections 8, 8, ... are provided at approximately equal intervals in the middle of the inside. The pressing member 5 is fixed to the main body 4 so as to cover the end of the solar cell module 3, thereby attaching the solar cell module 3 to the main body 4. In addition, since the pressing member 5 is provided at the ends of two opposing sides of the solar cell module 3, which is approximately rectangular, the solar cell module 3 can be efficiently and stably fixed to the main body 4. Furthermore, the pressing member 5 is provided perpendicular to the approximately cylindrical main body 4, and holds the main body 4 with a straight portion having a curved surface, making the pressing member 5 a straight member and enabling the pressing member 5 to slide with a simple configuration.

[0028] The multiple engaging portions 8, 8, ... provided on the pressing member 5 are adapted to respectively engage with the multiple engaged portions 9, 9, ... provided on the main body portion 4. Specifically, the engaging portions 8 are formed of plate-like members that are substantially inverted L-shaped in side view, and in the locked state, the tips of the engaging portions 8 are inserted into slits that are the engaged portions 9 of the main body portion 4, and when the pressing member 5 is slid upward relative to the main body portion 4, the engaging portions 8 and the engaged portions 9 are in an engaged state in which they do not move in directions away from each other.

[0029] As shown in FIG. 4, the engagement portion 8 of the pressing member 5 has an inclined surface 10 formed thereon. When the pressing member 5 slides in the direction to be locked, the inclined surface 10 comes into contact with the engaged portion 9 of the main body 4, and as the sliding movement proceeds, the pressing member 5 is drawn toward the main body 4 along the inclined surface 10. In addition, since a plurality of the engagement portions 8 are provided and the inclined portions 10 are all formed at substantially the same angle, the pressing member 5 is attached so that each portion is pressed against the main body 4 in the same manner by the action of the inclined portions 10, 10, ... with the engaged portion 9, and therefore the product has good assembly accuracy. As described above, the specific shape of the inclined portions 10 is all substantially the same shape, which has the advantage of making the manufacturing process easier, but the configuration is not limited to this, and the shape may be different depending on the position, for example, to absorb manufacturing errors or to adjust the force holding the solar cell module 3. In addition, the engagement portions 8 are not limited to being arranged in a straight line, but may be arranged in two rows or in other arrangements.

[0030] A plate-like member 11 is provided between the pressing member 5 and the solar cell module 3, which, in the locked state, exerts a force in a direction separating the pressing member 5 from the solar cell module 3. An operating unit 6 for operating the sliding movement of the pressing member 5 in the up and down direction is provided at the upper end of the pressing member 5, and a fastening member 12 for fixing the pressing member 5 so that it cannot slide is provided at the lower adjustment end.

[0031] As shown in FIGS. 3 and 4, the operation unit 6 is composed of an adjustment screw portion 13 provided at the upper end of the pressing member 5 and a base portion 14 provided at the upper end of the main body portion 4.

[0032] The adjustment screw part 13 is composed of a bolt 13a and two nuts (adjustment nut 13b, fixed nut 13c), and the bolt 13a is provided substantially vertically on the upper surface of the upper end of the pressing member 5, which is bent substantially vertically outward. The base part 14 is a plate-shaped part provided on the cover member attached to the upper end of the main body part 4 so as to protrude further outward from the outer circumferential surface of the main body part 4, and has a hole for inserting the bolt 13a. The adjustment nut 13b is provided on the upper side of the base part 14 of the bolt 13a inserted into the hole of the base part 14, and the fixed nut 13c is provided on the lower side of the base part 14. Therefore, when the adjustment nut 13b is tightened against the bolt 13a in the unlocked state of FIG. 3(a), the adjustment nut 13b is pressed against the base part 14, and the bolt 13a pulls the pressing member 5 upward, and as a result, the pressing member 5 slides relative to the main body part 4. In this state, the fixing nut 13c is tightened until it abuts against the base portion, resulting in the locked state shown in Fig. 3(b). At this time, the inclined surface 10 provided on the outer surface of the engaging portion 8 abuts against the engaged portion 9 of the main body portion 4, and a force acts on the pressing member 5 and the main body portion 4 in a direction that brings them closer together. As a result, in the locked state, the pressing member 5 and the main body portion 4 are firmly connected, and the solar cell module 3 sandwiched between them is also firmly fixed.

[0033] The operation unit 6 is covered by the protective cover 7 so that it cannot be seen from the outside. The protective cover 7 has a cylindrical shape with a lid and is placed on the operation unit 6 from above to cover the upper end of the main body 4 including the operation unit 6. Since the operation unit 6 is covered by the protective cover 7, the operation unit 6 is not exposed to the public and cannot be easily touched in this state, so that the pressing member 5 cannot be slid, and as a result, the compatible battery module 3 can be prevented from being stolen. This is also apparent from the outside, and the product as a whole is configured to be less likely to be the target of vandalism, etc., and can be used stably for a long period of time. The protective cover 7 covers the operation unit 6 in both the locked and unlocked states of the pressing member 5, making it safer, but it is not limited to this configuration, and the protective cover 7 may be configured to cover at least the operation unit 6 in the locked state, and may be configured in this way to make it simpler.

[0034] A plate-like member 11 is provided between the main body 4 and the pressing member 5. This plate-like member 11 is formed in a strip shape, and the cross section in the short direction is bent in two small steps so that the center protrudes outward. The plate-like member 11 having such a cross section is attached between the main body 4 and the pressing member 5 in a state in which the pressing member 5 is pressed against the main body 4. In other words, the solar cell module is pressed against the main body by the elastic force of the plate-like member 11 generated between the main body and the pressing member in the locked state, so that the solar cell module 3 is fixed more firmly. In addition, the plate-like member 11 is provided with the same number of slit-like holes 15, 15, ... at positions corresponding to the multiple engaging portions 8, 8, ... of the pressing member 5, so that the engaging portions 8 are inserted into these holes 15 and engaged with the engaged portions 9 of the main body 4.

[0035] As shown in Fig. 5, a fastening member 12 is attached to the lower end of the pressing member 5. This fastening member 12 fixes the main body 4 and the pressing member 5 via a plate-like member 11, and in this embodiment, a special bolt is used. This fastening member 12 prevents the pressing member 5 from sliding relative to the main body 4, and in combination with the operating part 6 at the upper end, it provides a higher crime prevention effect.

[0036] In this embodiment, a pole-type solar power generation device is shown as an example of a method of using a solar power generator, but the solar power generator according to the present invention is not limited to such use and can be widely applied to products using flexible solar cell modules in general, and can be used for things that are partially or entirely curved, such as the roofs of buildings and garages and the bodies of automobiles. In addition, there are no restrictions on the materials of the components of the solar power generator, including whether they are constructed as a single unit, and they can be widely adopted, but they may be made strong by using metal, lightweight by using synthetic resin, or made of other materials or a combination of multiple materials. Furthermore, general fixing products such as adhesive tape can be used appropriately to attach each member, including temporary fixing and auxiliary purposes. [Explanation of symbols]
