Description

The present invention relates to a mounting base for a solar cell module and a solar power generation device.
In more detail, the frame uses a lip-shaped grooved steel for the frame and the strut, and a concrete secondary product having a predetermined shape for the base member, and connects the frame, the strut, and the base member. The present invention relates to a structure in which a surface having an opening of a lip-shaped channel steel and a plane portion other than the opening are connected using a fixing auxiliary member.

In recent years, solar power generation has been attracting attention from the viewpoint of preventing global warming, and it is expected that solar power generation facilities will be popularized by the “surplus power purchase system for solar power generation” started in FY2009. ing.
In addition, the nuclear power plant accidents caused by the Great East Japan Earthquake caused a series of shutdowns of the nuclear power plant, resulting in shortage of power in each region. Therefore, the introduction or introduction of solar power generation facilities in companies, local governments or general households is being studied more than ever.

  In addition to those installed on the roof, the photovoltaic power generation equipment is also installed on the ground. As an example of a member used when installing on the ground, a solar panel (“Solar A platform for battery modules (also called “battery modules”) has been proposed.

  A solar panel pedestal according to Patent Document 1 includes a plurality of support columns erected on a base, a plurality of beam members fixed to the plurality of support columns in a posture substantially parallel to the surface of the base, and an upper surface of each beam member A plurality of angle-adjusting brackets that are attached to each other, and a gantry frame that is fixed to each angle-adjusting bracket at an angle corresponding to the arrangement angle of the solar panel and on which each solar cell module is mounted and attached. An angle adjustment mechanism capable of fixing the gantry frame at an arbitrary height position with respect to the angle adjustment fitting is provided.

  The solar panel gantry having the above-described configuration can be easily assembled without requiring a precise angle setting in advance when arranging the solar cell modules in a plane, and can be easily assembled at the construction site. It can be adjusted.

Registered Utility Model Gazette No. 3171824

On the other hand, the solar panel mount of Patent Document 1 is
(1) Since the shape of the gantry frame is special and not a general-purpose product, new equipment investment is required for manufacturing, and the economic burden on the practitioner until mass production is made is large. It takes a long time to procure, and the construction period including the material procurement period becomes longer.
(2) A structure in which a foundation portion (foundation base Ra) of the gantry is provided separately for each column (see FIG. 1 and FIG. 2 of Patent Document 1), and the structure is an operation for arranging the foundation portion. Takes time and effort to adjust the position in the vertical and horizontal directions.
(3) Structurally, each separated base part is likely to be displaced from the position where it was originally installed due to vibration or the like, and if the basic part is displaced, there is a possibility that the solar panel mount itself may be distorted.
There was a problem.

In order to solve the above-mentioned problem (1), the present inventor is light in weight and can be obtained and handled from commercially available general-purpose products in order to avoid a new capital investment in manufacturing a mount for a solar cell module. We focused on the fact that the use of easy-to-lip channel steel (hereinafter referred to as “lip channel steel”) makes it easier to obtain materials and expands the range of delivery dates and price options.
Furthermore, in order to solve the problems (2) and (3), the present inventor has also conceived a structure in which the separated base portions are connected in either or both of the vertical and horizontal directions.

  However, since the gantry using the lip channel steel is relatively light and the solar cell module is easily blown by the wind, the solar power generation apparatus using the gantry is shifted from the installation position with the gantry by the strong wind, There is a possibility of tipping over.

  Moreover, although the solar power generation device is installed outdoors and is unavoidable to be exposed to rain and snow, since the lip groove steel has an opening extending over the entire length on one surface, For the purpose of rust prevention, it is necessary to prevent rainwater from entering and collecting in the opening.

  In order to solve this problem, it is required to assemble the lip groove steel so that at least the opening is not on the upper side, that is, the opening is on the lower side as much as possible. However, for example, when assembling the pedestal frame on the upper end of the support, there is a problem that if the opening is on the lower side, there is no object for forming the bolt through hole in the opening, so that the connection with the support is not successful.

(Object of invention)
Therefore, the object of the present invention is a pedestal for solar cell modules using lip groove steel and concrete secondary products that are general-purpose products as each member constituting the pedestal, and its installation work is simple. In addition, when connecting the surface having the opening of the lip groove shape steel and a plane portion other than the opening, the fixing auxiliary member is used so that the opening can be attached without directing it upward. Is to provide.

  The present invention is to provide a solar power generation apparatus in which a solar cell module is installed on the gantry.

The means of the present invention taken to achieve the above object are as follows.
(1) The present invention includes a frame on which the solar cell module is placed, a plurality of support columns that support the frame, and a plurality of base members to which the lower ends of the support columns are fixed. The grooved steel with a lip is formed of a web part, a flange part extending in a direction orthogonal to the web part from both ends of the web part, and the web part from a tip of the flange part. A concrete secondary product having a columnar body lying on the side with a lip portion extending in parallel and an opening between the tips of the opposing lip portions, each of the foundation members being triangular, square, trapezoidal or semicircular in cross-sectional view The support is fixed to each of both ends thereof, and arranged in such a manner that the longitudinal direction of each base member is parallel to either the vertical or horizontal direction of the frame, and constitutes the frame. The grooved steel with a lip is disposed with the opening facing downward, and inside the grooved steel with the lip, a fixing auxiliary member having a contact portion that contacts the back side surfaces of the two lips is provided. The fixing auxiliary member faces the opening between the tips of the opposing lip portions, the contact portion of the fixing auxiliary member is brought into contact with the inner side surfaces of the two lips, and the fixing auxiliary member is pulled toward the support column side. By this, it is a mounting base for solar cell modules including having fixed the grooved steel with a lip | rip of the said flame | frame to the upper part of the said support | pillar.

(2) In the invention, the fixing auxiliary member is plate-shaped, and the contact portion is a notched portion obtained by cutting out the plate thickness of the lip over the entire length of both sides of the fixing auxiliary member, and between the notched portions. Protrusions that fit into the openings between the tips of the opposing lip portions are formed, and when both lips of the grooved steel with lips are brought into contact with the notches, the surface side of both lips and the protrusions The surface side may be the same height.

(3) The present invention is a photovoltaic power generation apparatus in which a solar cell module is installed on the mounting table.

  The “solar cell module” referred to in the present specification and the claims of the present application is, for example, a plurality of cells (single elements of a solar cell) connected in series or in parallel and protected with resin, tempered glass, a metal frame or the like. It is also referred to as “panel” and is used to include strings (panels or modules arranged in series and connected in series) and arrays (strings connected in parallel). In addition, a device or member used in solar power generation such as a storage battery or a power conditioner may be included. In addition, the "solar power generation device" referred to in the present specification and the claims of the present application is used to indicate a combination of a solar cell module and a gantry thereof.

  The “frame” referred to in the present specification and claims of the present application is a structure that is assembled directly through the upper portion of the column, for example, an L-shaped angle (hereinafter referred to as “angle material”), etc. Also good.

  The “base member” in the present specification and the claims of the present application refers to the strength with which each column can be installed (or each column via an angle member), the weight that prevents the solar cell module from being blown by the wind, and availability. In order to satisfy the requirement of being easy and inexpensive, a commercially available concrete secondary product with a predetermined shape is preferable, and a high nut (also referred to as a spacer nut or long nut) embedded in the upper or upper surface is caught for convenience of transportation. However, the present invention is not limited to this. For example, it may be fixed to the hole formed in the base member using an anchor bolt, or when the base member is formed. A known technique such as an embodiment in which an anchor bolt is embedded may be used.

  Examples of the shape of the “fixing auxiliary member” referred to in the present specification and the claims of the present application include, but are not limited to, a square plate, and other shapes such as a circle, an oval, a polygon, and the like. Even if it is the well-known shape of this, it is sufficient to have the said contact part formed wider than the opening part of a lip channel steel.

(Work)
The operation of the platform for the solar cell module and the photovoltaic power generation apparatus according to the present invention will be described.

In the invention of (1) or (2), the gantry arranges each base member such that either the longitudinal or lateral direction of the frame is parallel to the longitudinal direction of the base member, and the lower part of each column is the base member. It adheres at intervals in the longitudinal direction.
A plurality of lip channel steels are combined at the top (or top) of the strut (eg, in a horizontal grid) to form a frame.

When the lip groove steel constituting the frame is placed with the opening facing downward, an auxiliary fixing member is placed inside the lip groove steel so that it faces the opening between the tips of the opposite lip portions. Then, the contact portion of the fixing auxiliary member is brought into contact with the inner side surfaces of both lips, and the fixing auxiliary member is pulled toward the support column side, thereby fixing the grooved steel with a lip of the frame to the upper portion of the support column.
In addition, the use of the fixing auxiliary member according to the present invention includes the connection between the lip groove steels other than the frame and the upper portion of the column, and the plane portion other than the opening and the surface having the opening of the lip groove steel. It is also included to use the fixing auxiliary member when connecting the two.

  In the invention of (2), when using the fixing auxiliary member, the protrusion formed on the fixing auxiliary member is fitted into the opening between the tips of the opposing lip portions, and the lip groove is formed in both notches. When the back side surfaces of both lips of the shape steel come into contact with each other, the surface side of the both lips and the surface side of the protrusion are at the same height.

  In addition, it becomes a solar power generation device by installing a solar cell module on the mounting base in any one of said (1) thru | or (2).

  Since the platform for the solar cell module according to the present invention is configured by using lip groove steel and concrete secondary products, which are general-purpose products, it is easy to procure members as compared with the case of using dedicated products. Therefore, it can be expected to shorten the work period including the material procurement period, and to reduce labor and cost.

  In addition, since the foundation member is a concrete secondary product, it has a weight that will not be blown by the wind. When installing the foundation member and each column, the length of each foundation member is the same as the longitudinal or lateral direction of the frame. Since it is only necessary to arrange the columns so that the directions are parallel to each other and install the columns, the position adjustment at the time of setting each column is simpler and the work efficiency is better than that in which individual foundation members are provided for each column. In addition, since it is the form with which the base member under the support | pillar was connected, the intensity | strength of the mount frame with respect to a vibration or rocking | fluctuation improves compared with what has separated the base member.

  When installing a solar power generation device, if the installation location is a factory ruins, etc., soil inspection and notification may be required when digging the land depending on the laws and regulations concerning contaminated soil. Although it has been a cause of labor and cost increase, the present invention can be expected to reduce labor and cost, and to shorten the period until permission is granted, since it is not necessary to dig up by simply placing the base member on the ground.

  In the invention using the fixing auxiliary member in the invention of (2), the surface side of both lips of the lip channel steel and the surface side of the protrusion are the same height, so that the contact between the lip channel steels The area is increased, the load at the time of fixing is dispersed, and the load on the specific part is reduced.

(9th step)
A gantry M is formed by the first to eighth steps. Note that the order of the steps can be arbitrarily changed except those that cannot be changed due to the procedure of the assembly work.
The solar power generation device P is completed by mounting and fixing the solar cell module S on the beam 1 of the gantry M formed.

(Work)
The operation of the solar cell module mount M and the solar power generation device P will be described.

  Since the gantry M is configured by using lip groove steel and concrete secondary products, which are general-purpose products, it is easy to procure members, compared to the case of using a dedicated product, It can be expected to shorten the construction period, and save labor and costs. In particular, for the purpose of selling electricity, the initial cost required for installation has never been less, but it can be expected that the initial cost will be low if it is a general-purpose product such as a lip groove steel.

  When assembling the gantry M, each component member is connected using a bolt 71 and a nut 72 (only the bolt 71 depending on the location). Through the use of fixing auxiliary members 6a and 6b, the surface of the lip channel steel having the opening and the plane portion other than the opening are connected. That is, since the gantry M is formed without a welding operation, the operation can be performed even when there is no welding engineer or there is no welding tool. Further, according to the angle members 5a to 5g in which the insertion holes for attaching the respective members are provided in advance, it is not necessary to adjust the attachment positions of the respective members.

Since the foundation member 3 is a concrete secondary product, the foundation member 3 has a weight that does not allow it to be blown by the wind. In addition, when installing the long and short struts, the base member 3 only needs to be installed in parallel with a space in the longitudinal direction with respect to the gantry M, so that a separate base member is provided for each strut. In comparison, the position adjustment at the time of installing each column is simple and the work efficiency is good.
Further, since the foundation member 3 is connected in the short direction of the gantry M, the strength of the entire gantry against vibration or swinging is improved as compared with those in which the foundation members are separated from each other.

  In addition, when installing solar power generation equipment, if the installation location is a factory ruins, etc., soil inspection and notification may be required when digging the land depending on the laws and regulations concerning contaminated soil, and foundation work is performed However, since the photovoltaic power generation apparatus P according to the present invention simply disposes the base member 3 on the ground and does not need to be dug down, the time until the labor and cost are reduced and the permit is granted. Shortening can be expected.

  The strength of the gantry M is further improved by providing the brace 41 with the brace 41, the cane 42, and the horizontal member 43, which are reinforcing members.

  The terms and expressions used in the present specification and claims are for illustrative purposes only, and are not intended to be limiting in any way. The features described in the present specification and claims and their terms There is no intention of excluding some equivalent terms and expressions. It goes without saying that various modifications are possible within the scope of the technical idea of the present invention.
