Description

The present invention relates to an installation for solar power generation that can be used in both the snowy season and the non-snowy season.

In recent years, research on solar power generation as an environmentally friendly energy source has been promoted, and solar cell modules are arranged in various places for power generation. Generally, the solar cell module 401 is configured by sealing solar cells in an outer frame such as glass, and as shown in FIG. 4, a support column 403 is vertically set on a base 402 and held on the support column. Or are held and installed between a plurality of standing columns.

However, in areas where there is a lot of snow, such as Hokkaido and Tohoku, the power generation efficiency is reduced due to snow and frost on the solar cell module due to snow accumulation, and the solar cell module and the light using it are snowy. It will even be buried in the wall, and it will not work at all.
In order to prevent the solar cell module from being buried in the snow and to ensure the function and performance of the power generation, it can be installed at a high place or with a solar power generation system in order to correspond to the area and time of recording 1m class snowfall. Increasing the height of things can be cited as a countermeasure.
However, when a solar power generation installation or a solar light using the same is used for a garden light, it is unlikely that the garden light is installed at a high place, apart from the solar power generation installation. The purpose of the garden light is not to illuminate a wide area from a high place, but to illuminate the ground and the vicinity from a low place close to the ground. For this reason, the device itself has a low illuminance to illuminate a wide range, and in this respect is different from a streetlight.
And solar power installations and garden lights that are so tall that they cannot be buried in snow become large, for example, 2M-class street lights, and the brightness of the garden lights becomes darker. Not suitable for installation. Especially in the non-snowy season such as summer, it is unsightly that there is an installation with a high height, and it is inconvenient to use a stepladder etc. because it is out of reach for maintenance of the solar cell module. That said, it is uneconomical and inefficient to use two types of solar power generation installations and garden lights for the snowy season and non-snowy season.
For this reason, it is difficult for ordinary households and the like in areas with a lot of snow to use garden lights in winter as in other areas.

Some conventional solar power generation installations have taken into consideration measures against snow accumulation, but are lacking in the viewpoint of measures against burying solar cell modules in snow.
For example, as a conventional snow cover measure, the installation angle of the solar cell module is slanted or vertical, and the angle can be adjusted to prevent snow cover and to prevent snowfall and snowfall. There is what I did.
In invention of patent document 1, the installation method of the solar cell module which can adjust the angle of a solar cell module is introduced by extending and contracting some of the support | pillars provided in order to support a solar cell module group. . However, only the adjustment of the angle of the solar cell module cannot cope with the solar cell module being buried in snow.

In invention of patent document 2, the solar cell power supply device and the street lamp as an Example are introduced. The invention is a structure that is not easily affected by wind, and uses a secondary battery for increasing the charging efficiency in winter, but since there is no countermeasure against burying in snow, it is attached to a high place to avoid burying, It is necessary to attach the solar cell module to a street light that is so tall that it is not affected by the amount of snow. In this respect, there is exactly the above problem, and it is difficult to use it in ordinary households.

The invention of Patent Document 3 uses a mobile support solar system with support legs and struts that expand and contract. However, the extension mechanism in this invention makes the solar system horizontal when the support legs are inclined or uneven. As for the support, the purpose of the support is to fold and make it compact for the movement and storage of the solar system itself. It is clear that it is buried in snow.

Due to the above background, it is suitable for use in solar power generation facilities with high convenience that can be used in both snow and non-snow seasons in areas with a large amount of snow, and for use in ordinary households using such facilities. Solar light is desired.

It is a figure which shows one embodiment of the photovoltaic power generation installation thing by this invention. It is a figure which shows the example of the support | pillar expansion-contraction mechanism of the solar power generation installation by this invention. It is a figure which shows one embodiment of the photovoltaic power generation installation of this invention provided with illumination.

Furthermore, the solar power generation installation of the present invention and the solar light using the solar power generation installation are strengthened by increasing the amount of the solar power generation installation, tilting / vertical installation of the solar cell module, snow / frost on the solar cell module. -The effect can be enhanced by adding a transparent coating to prevent icing and dirt.

FIG. 1 is a diagram showing an embodiment of a photovoltaic power generation installation according to the present invention. A column composed of cylindrical columns (lower) 101 and columns (upper) 102 having different diameters extends upward, and the columns are expanded and contracted by sliding the column (upper) 102 up and down. The solar cell module 401 is preferably attached to the top or top of the side of the support (upper) 102 in order to avoid being buried in snow.
1-A is a solar cell module 401 mounted obliquely with respect to a vertical column, 1-B, 1-C are solar cell modules 401 mounted vertically, and 1-A, 1 -B attaches the solar cell module 401 to one column, and 1-C holds it between two columns. By attaching the solar cell module 401 diagonally or vertically, it is possible to enhance the sliding effect of snow and water droplets adhering to the surface of the solar cell module 401.
On the surface of the attached solar cell module 401, it is preferable to apply a coating agent that is resistant to snow accretion, frost formation, freezing, and dirt adhesion, or to install a replaceable film on which the coating is applied. When snow or frost adheres to the surface of an object, the adhered portion accumulates and grows on the nucleus, and dirt attached to the surface of the object also causes frost to adhere to the nucleus and grow.
Therefore, a material having water repellency, water slidability, snow slidability, and a property that makes it difficult to get dirt is desirable as a coating agent. Fluorine compounds and silicon compounds are well known as this material, and titanium oxide can also be used as a photocatalyst. Titanium oxide is hard to peel off and has a high snow-proofing effect, and also has anti-frosting properties because it has super hydrophilicity that can decompose dirt and wash it away with rainwater.
In addition, since a coating is given on the solar cell module 401, this coating must transmit sunlight as much as possible in order not to reduce the power generation efficiency. If at least the coating agent is transparent, visible light can be transmitted, but it is desirable to transmit light having a spectrum other than visible light. In this respect, since titanium oxide absorbs ultraviolet rays, it can be said that the power generation efficiency based on ultraviolet rays decreases.
As an example of the coating agent, the invention of Patent Document 4 is excellent in storage stability, does not repel or shift when applied to a substrate, and is dried in a short time at 100 ° C. to 250 ° C., producing a uniform and interference color. Titanium oxide film forming liquid that can form a titanium oxide film that is difficult, transparent, high in hardness, and has excellent adhesion, wear resistance, durability, and photocatalytic activity. It can also add durability against snow, freezing, and condensation. It seems.
Titanium oxide, fluorine-based and silicon-based sprays are also commercially available.
In the maintenance of the coating, the coating of Patent Document 4 requires drying at a high temperature, and it is difficult for the user to perform the maintenance directly. Therefore, it is suitable to replace the coating film. Is unnecessary. Commercially available sprays are convenient because they can be coated by the user, but at least annually, it should be treated immediately before snow falls.

FIG. 2 is a diagram showing an example of a column expansion / contraction mechanism of a photovoltaic power generation installation according to the present invention.
2-A is a pin lever type, and the expansion and contraction of the support column pulls up the support column (upper) 102 and opens a plurality of locking tools 201 attached to the support column (lower) 101 at different heights on the side surface of the support column (upper) 102. The height of the support is fixed by inserting it into the provided locking tool insertion port 202. The shape of the locking tool 201 is not limited as long as it can be inserted into the locking tool insertion port 202 and fixed, such as a pin, metal fitting, or chain.
2-D shows such an example. A pin-shaped locking tool 201 is inserted into a locking tool insertion port 202 between the support (upper) 102 and the support (lower) 101.
2-B is a ratchet type and is often used for walking sticks. The push button 203 provided at the lower part of the side surface of the support (upper) 102 protrudes to the outside through a plurality of adjustment holes 204 formed at different heights on the side of the support (lower) 101. Stretching of the column is performed by pulling up the column (upper) 102 as in 2-A, but the column (upper) 102 is pulled up while pushing the push button 203 into the column (lower) 101. When the height position of the push button 203 becomes equal to the height position of the adjustment hole 204, the push button 203 goes out through the adjustment hole 204 and fixes the height of the column.
In 2-E, a push button 203 provided on the support (upper) 102 passes through a hole opened in the support (upper) 102 and is fixed to the inner wall of the support (upper) 102 via a bent leaf spring 208. Has been. For this reason, if the push-in button 203 is pushed, it will be retracted, and if it is released, it will return. The ratchet can be realized by various other means.
2-C is a jump type and is often used for umbrellas. A gas spring operation button 205 is attached to a side surface of the support (lower) 101, and the gas spring operation button 205 is connected to a gas spring 206 with a lock built in the support (lower) 101 with a wire. A partition 207 is installed on the gas spring 206 with lock at the boundary with the support (upper) 102 inside the support (lower) 101. While the gas spring operation button 205 is being pressed, the piston rod of the gas spring with lock 206 is extended, and when the gas spring operation button 205 is released, the piston rod can be fixed at its length. When the piston rod of the gas spring with lock 206 extends, the front end in the extension direction of the gas spring 206 with lock pushes up the partition 207 and pushes up the column (upper) 102. According to this method, the column can be fixed at an arbitrary height, and since it is not necessary to make a hole on the side surface of the column (lower) 101 except for passing the gas spring operation button 205, the appearance is good. In addition, if the gas spring has a piston rod with various extension speeds and uses a slow extension speed, there is no risk of injury by hitting the head or other body due to the rapid expansion and contraction of the column.
As an extension mechanism other than the above, although not shown, a winch mechanism with a handle such as a volleyball extension pole, means using a transmission means such as a switch, a power source, a control electric circuit, a motor and a gear, and a belt are also possible. .
In addition, as shown to 2-F, in order to slide smoothly with the support | pillar (lower) 101 and the support | pillar (upper) 102, it is convenient to provide the rotary wheel 209 which touches and rolls on both wall surfaces.
Furthermore, it is important to reduce the weight load that lifts the support (upper) 102 with the solar cell module when expanding and contracting, as shown in 2-G, between the support (lower) 101 and the support (upper) 102. It is preferable to provide a push-up mechanism 210 by a spring or hydraulic pressure or air pressure that pushes up the support (upper) 102. In 2-H, a support column 211 is provided on a column (lower) 101, and a column (upper) 102 and a balance weight 213 that is a weight are connected to the support column 211 via a pulley 212. In this case, the weight of the support (upper) 102 including the solar cell module and the weight of the balance weight 213 are balanced, so that the support (upper) 102 can be moved up and down with a small force.

FIG. 3 is a diagram showing an embodiment of the photovoltaic power generation installation of the present invention provided with illumination. As an external appearance, the solar cell module 401 is attached to the upper part of the column of the illuminating lamp. It is desirable that the lighting 301 and the solar cell module 401 are installed at a position as high as possible, even if there is expansion and contraction of the column, from the viewpoint of avoiding burying in snow. Further, when the lighting 301 is installed so as to emit light downward, even when the snow 301 is not piled up and the lighting 301 is away from the ground, the feet can be brightly illuminated.
For example, in the 3-A shape, the illumination 301 and the solar cell module 401 are arranged vertically, and it is difficult to attach the solar cell module 401 to the upper part of the column. Moreover, if the solar cell module 401 is attached to the top, it will snow, and if it is attached near the top, the illumination 301 will be hidden behind the solar cell module 401.
In that respect, in the shape of 3-B, the lighting 301 is installed on the opposite side of the solar cell module 401 attached to the upper portion of the support column (upper) 102 by extending a branch from the support column. Each 401 can be attached to the top of the column. Although not shown, a method of curving the tip of the 3-B column (upper) 102 to the side opposite to the installation surface of the solar cell module 401, or a tip of each column (upper) 102 with the tip of the bifurcated fork. Also by means of attaching the lighting 301 and the solar cell module 401 to each other, they can be installed without interfering with each other.
In addition, although the support | pillar showed the state by which the support | pillar (upper) was inserted in the support | pillar (lower) in the figure, the reverse case is also possible. The support (lower) may or may not have a foundation to support it.

Since it is configured as described above, the solar power generation installation according to the present invention and the solar light using the solar power installation are adjusted by the height of the struts to prevent the solar cell module from being buried in the snow during the snowfall period, and to be maintained. Reduces labor during work and prevents the appearance impression from deteriorating when there is no snow.
And if it is equipped with lighting, it becomes a solar light that can be adjusted in height according to the snow conditions and time of use area, and can be used as a garden light that can adjust the effect of light irradiation by adjusting the height.
Furthermore, the solar power generation installation of the present invention and the solar light using the solar power generation installation are strengthened by increasing the amount of the solar power generation installation, tilting / vertical installation of the solar cell module, snow / frost on the solar cell module. -The effect can be further enhanced by adding a transparent coating to prevent icing and dirt.
Therefore, the solar power generation installation of the present invention and the solar light using the same can be used throughout the year even in an area with a large amount of snow. It contributes to the spread of solar lights and is extremely industrially useful.
