Description

  The present invention relates to a photovoltaic panel pedestal connecting portion cover (hereinafter simply referred to as a “connecting portion”) that covers a connecting portion between a foundation pile of a mounting base for a photovoltaic power generation panel (solar panel) and a column connected to the foundation pile. And a photovoltaic power generation panel mount using the connecting portion cover.

  Since the Fukushima nuclear power plant accident caused by the Great East Japan Earthquake, renewable energy (natural energy, clean energy) including solar power generation has attracted attention. Conventionally, solar panels used for photovoltaic power generation have been mainly installed on the roof. However, the establishment of a “Fixed Purchase System” that obliges electric utilities to procure electricity generated from renewable energy sources (solar, wind, hydropower, geothermal, biomass) at a fixed price determined by the government for a certain period of time. As a result, field-type solar power generation facilities installed on the ground (for example, idle land, mountain forest, golf course ruins, etc.) have begun to spread. In order to install the photovoltaic power generation facility on the ground, a gantry (solar panel gantry) is provided on the ground, and the solar panel is installed and fixed thereon.

  There are various types of foundations for solar panel mounts, including concrete foundations as well as methods for driving steel frames into the soil and screw piles with spiral wings (screws) around the piles. Can be mentioned.

  In any method, it is common to construct a pedestal by connecting a column on a foundation provided in the ground and connecting a frame material such as a pipe or a rod to the column (for example, Patent Document 1 and Non-Patent Document 1).

  The foundation pile and the support column need to be securely connected to prevent them from coming off, and it is necessary to prevent rainwater and dust from entering from the connecting portion. Moreover, it is necessary to prevent the foundation pile and the column from being disconnected. Conventionally, there are various methods for connecting the foundation pile and the column. As a main method, there is a method of connecting with screws and pins and further hardening the periphery of the screws and pins with mortar, concrete or the like.

  In any of the above connection methods, it takes time and effort to perform the construction at the installation site of the gantry, and the construction is troublesome, resulting in a high cost. In particular, with mortar and concrete hardening methods, it takes time to pack mortar and concrete, mortar and concrete crack and break due to aging, and rainwater and dust enter and rust is generated. There is a concern that the pin will slip out.

  In order to solve the above-mentioned problems, there is a demand for a material and a structure that can prevent the pins from coming off even after long-term use and prevent rainwater and dust from entering.

  The object of the present invention is to easily cover the outer periphery of the connecting part of the foundation pile and the column connected by the connecting tool, and to cover the outer periphery of the connecting part, to prevent the connecting tool from falling off, and to reduce the manufacturing cost and the construction cost. Another object of the present invention is to provide an inexpensive connection part cover and a photovoltaic power generation panel mount using the connection part cover.

  The connecting part cover of the present invention is a cover used for connecting a support pillar on a foundation pile inserted into the ground, and covers the outer periphery of the connecting part between the foundation pile and the support pillar connected thereto. A bottom opening that can be placed on the foundation pile from above is formed on the bottom surface of the cover body, and a foundation pile fitting space that can be placed on the outer periphery of the foundation pile is formed in the cover body. A column insertion hole that can insert a column is opened on the upper surface, and a connector fitting space that can be put on a connector (for example, a pin) that connects the foundation pile and the column inserted therein is formed in the cover body. The foundation pile fitting space and the column insertion hole communicate with each other vertically, and the connector fitting space communicates with the foundation pile fitting space beside the foundation pile fitting space and is opened at the bottom surface of the cover body. The foundation pile fitting space on the outer periphery of the foundation pile Cover the foundation pile, the strut, and the connecting tool by covering the connecting tool fitting space to the connecting tool that connects the support pillar and the foundation pile inserted from the pillar insertion hole to the foundation pile fitting space. The connector can be prevented from falling off.

  The connection cover of the present invention can be made of resin. In addition, the diameter of the support hole can be made somewhat larger or substantially the same as the outer diameter of the support so that there is no gap between the support hole and the support post inserted into it. In this case, when the diameter of the column insertion hole is gradually narrowed from the upper side to the lower side (lower taper), and the column is inserted into the column insertion hole, the outer peripheral surface of the column gradually becomes closer to the column insertion hole. Thus, it is possible to prevent a gap from being formed between the column and the column insertion hole. In addition, when an elastic packing is fitted to the inner periphery of the column insertion hole, and the column is inserted into the packing, the outer peripheral surface of the column closely contacts the packing, that is, between the column and the packing, that is, the column insertion hole. It is also possible to prevent a gap between them.

  In the photovoltaic power generation panel mount of the present invention, a foundation pile with spiral wings is inserted into the ground, and a pillar is connected on the foundation pile, and the photovoltaic panel is installed and fixed by the pillar and other members It is a photovoltaic power generation panel stand constructed so that the foundation pile is covered with resin at least at the outer periphery of the insertion part into the ground. It is connected and the outer periphery of the connection part of a foundation pile and a support | pillar is coat | covered with the said connection part cover.

The connecting portion cover of the present invention has the following effects.
(1) Cover the outer periphery of the foundation pile with the foundation pile fitting space, and simply put the fitting fitting space on the coupler that connects the pillar and the foundation pile inserted from the pillar insertion hole to the foundation pile fitting space. Moreover, the outer periphery of the connection part of a foundation pile and a support | pillar and a connection tool can be coat | covered easily, and construction cost is also cheap.
(2) By covering the connecting portion cover of the present invention, the connecting tool that connects the foundation pile and the support column is prevented from falling off, and a reliable connection can be secured over a long period of time.
(3) Since mortar, concrete, etc. are not used, even if it uses for a long period of time, it is hard to deteriorate over time, and the waterproofness and dustproof of a connection part can also be ensured over a long period of time.

The photovoltaic power generation panel mount of the present invention has the following effects.
Since the connection part of a foundation pile and a support | pillar and the outer periphery of a connection tool are coat | covered with the said connection part cover, the connection of a connection part is reliable, and it becomes a mount stand excellent in waterproof, dustproof, and rust prevention.

(Embodiment of connecting part cover)
An example of an embodiment of the connecting portion cover of the present invention will be described with reference to FIGS. FIG. 1 shows an example of use of a connecting portion cover. A support pillar 2 is inserted into a foundation pile 1 inserted into the ground and connected with a retaining pin (connector) 3, and the foundation pile 1, support pillar 2, and connection tool 3. The connection part cover 4 is put on the outer periphery of the connection part.

  Details of the connecting portion cover 4 of FIG. 1 are shown in FIGS. The connecting portion cover 4 is formed with a bottom opening 6 that can be placed on the foundation pile 1 from above on the bottom surface of the cover body 5, and the foundation pile fitting that can be placed on the outer periphery of the foundation pile 1 in the cover body 5. A space 7 is formed, and a column insertion hole 9 into which the column 2 can be inserted is opened on the upper surface 8 of the cover body 5, and a connecting tool 3 that connects the foundation pile 1 and the column 2 inserted in the cover body 5. A connector fitting space 10 that can be covered is formed.

  The foundation pile fitting space 7 and the column insertion hole 9 communicate with each other vertically. The foundation pile fitting space 7 is a vertically long hole having an inner diameter that is slightly larger than the outer diameter of the foundation pile 1, opens to the bottom surface 11 of the cover body 5, and covers the outer periphery of the foundation pile 1 from the bottom opening 6. It is made to be able to. The column insertion hole 9 is a hole having an inner diameter that is slightly larger than or substantially the same as the outer diameter of the column 2, penetrates through the upper surface 8 of the cover body 5, and communicates with the foundation pile fitting space 7. When inserted, the foundation pile fitting space 7 can be inserted.

  The connector fitting space 10 is formed on the left and right sides of the foundation pile fitting space 7 and communicates with the foundation pile fitting space 7, and the bottom surface of the cover body 5 from a position slightly below the upper surface 7 a of the foundation pile fitting space 7. 11 to the bottom surface 11. The shape is a horizontally long rectangular shape, and is formed in a shape of a horizontally long rectangular hole that can be covered outside the connector 3.

  The cover body 5 can be made of various materials such as resin, rubber, and metal. When it is made of metal, a material coated or covered with a material (for example, resin) that is not harmful to the ground E into which the foundation pile is inserted is preferable. By the way, in the case of metal, if the surface is galvanized to prevent corrosion, there is a risk that zinc, which is a harmful substance, will elute into the ground E and contaminate the soil due to long-term installation.

(Usage example 1 of the connection part cover of this invention)
The connection part cover 4 of this invention can be covered on the outer periphery of the foundation pile 1, the support | pillar 2, and the connection tool 3 in the procedure shown to Fig.3 (a)-(d). The procedure is shown below.
1. As shown to Fig.3 (a), the foundation pile fitting space 7 of the connection part cover 4 is covered on the foundation pile 1 from the top.
2. As shown in FIG. 3B, the support column 2 is inserted through the support column insertion hole 9 of the connecting portion cover 4. At this time, the foundation pile 1 that covers the foundation pile fitting space 7 is inserted to the inside.
3. As shown in FIG.3 (c), the connection part cover 4 is lifted upwards rather than the connection part 12 of the foundation pile 1 and the support | pillar 2, and the horizontal hole 13 of the foundation pile 1 and the horizontal hole 14 of the support | pillar 2 are lined up horizontally. Alignment, the connecting tool 3 is inserted into both the lateral holes 13 and 14, the support 2 is fixed to the foundation pile 1, and the removal of the support 2 is prevented (the foundation pile 1 and the support 2 are connected).
4). As shown in FIG. 3 (d), the connecting portion cover 4 that covers the foundation pile 1 and the support column 2 is lowered, and the connector fitting space 10 is put on the outer periphery of the connector 3. Thereby, the connection part of the foundation pile 1 and the support | pillar 2 can be coat | covered, and the dropping of the connection tool 3 which connects the foundation pile 1 and the support | pillar 2 is also prevented.

(Usage example 2 of the connection part cover of this invention)
The connection part cover of this invention can be covered on the outer periphery of the foundation pile 1, the support | pillar 2, and the connection tool 3 in the procedure shown to Fig.4 (a)-(d).
1. As shown to Fig.4 (a), the support | pillar 2 is inserted into the foundation pile 1 from the top.
2. As shown in FIG. 4 (b), the horizontal holes 13 of the foundation pile 1 and the horizontal holes 14 of the support column 2 are aligned in a horizontal direction, and the connector 3 is inserted into both the horizontal holes 13, 14, so 2 is stopped and the column 2 is prevented from coming off (the foundation pile 1 and the column 2 are connected).
3. As shown in FIG. 4C, the connecting portion cover 4 is put on the support 2.
4). As shown in FIG. 4 (d), the connecting portion cover 4 that covers the foundation pile 1 and the column 2 is lowered, and the connector fitting space 10 is put on the outer periphery of the connector 3. Thereby, the connection part of the foundation pile 1 and the support | pillar 2 can be coat | covered, and the dropping of the connection tool 3 which connects the foundation pile 1 and the support | pillar 2 is also prevented.

  The connecting part cover 4 of the present invention covers the outer periphery of the connecting part of the foundation pile 1 and the support column 2 to prevent rainwater and the like from entering the foundation pile 1 and to prevent the foundation pile 1 from being rusted and corroded. Therefore, it is desirable to prevent rainwater from entering between the column insertion hole 9 of the cover body 5 and the column 2 inserted into the column insertion hole 9. For this purpose, the diameter of the column insertion hole 9 should be the same as the outer diameter of the column 2 so that there is no gap between the column insertion hole 9 and the column 1 inserted therein. If the diameter of the hole 9 is made the same as the outer diameter of the support 2, it becomes difficult to insert the support 2. Therefore, as shown in FIG. 5A, the diameter of the support insertion hole 9 is gradually narrowed from the top to the bottom. When the column 2 is inserted into the column insertion hole 9, the outer peripheral surface of the column 2 gradually comes into close contact with the column insertion hole 9, and there is a gap between the column 2 and the column insertion hole 9. You can make it impossible. If possible, an elastic rubber or resin packing 21 is fitted to the inner peripheral edge of the column insertion hole 9 as shown in FIG. 5B, and the column 2 is inserted into the packing 21. , The outer peripheral surface of the column 2 can be brought into close contact with the packing 21 so that there is no gap between the column 2 and the packing 21, that is, between the column insertion holes 9.

  Since the connecting portion cover 4 of the present invention prevents the connecting tool 3 that connects the foundation pile 1 and the support column 2 from dropping off, the connecting tool fitting space 10 is surely covered on the outer periphery of the connecting tool 3. To.

  As described above, the connection portion cover 4 of the present invention can cover the outer periphery of the foundation pile 1, the support column 2, and the connection tool 3, and can at least perform the functions of waterproofing, dustproofing, rust prevention, and preventing the connection tool from falling off. Other shapes, sizes, wall thicknesses, etc. can be used as long as the shape and structure are easy to mold resin. For example, when the thickness of the cover main body 5 is reduced in order to reduce weight, reduce costs, etc., the outer peripheral surface of the cover main body 5 can be reinforced by providing ribs or irregularities.
