Description

  The present invention relates to a gantry for supporting a solar panel and an installation method thereof.

  Recently, renewable energy is in the spotlight. One of them is power generation using solar panels, but if you want to install solar panels outside the roof, point them to the sun with a mount on the ground etc. (An angle of about 30 ° from the ground is suitable) Must be installed. The ground on which the gantry is installed is flat, but such land has high asset value, so it may not pay for solar power generation, which is not always efficient due to day and night, weather, etc. In addition, it may be better to use such land for other effective use. Furthermore, in order to generate electric power efficiently, it is better for the gantry to track the sun, but if an expensive tracking device is attached, it is often not profitable with solar power generation. Therefore, many solar panels are supported by a fixed base and receive sunlight.

  To that end, it is important to select a place where the gantry is installed, but if it is a place other than the above, it is basically a slope or slope facing south. Slopes and slopes include natural mountains, hills, hills or artificial railways, highways and river embankments, dams and ponds. In addition, although it divided into slope and slope here, both are slopes, and slope means a natural thing in slopes, such as a mountain, and a slope is artificial such as a river dike. In the following, both slopes and slopes are included. Since the former is natural, it is uneven, the slope is not uniform, and there are rocks. Also, grass and miscellaneous trees are prosperous, but the price is extremely cheap and it can be said that it is inexhaustible. On the other hand, the latter also exists in many ways, but once it is leveled, the slope is uniform (thus, it is more suitable for use than the slope). However, the length of the slope is not so long, and there are many restrictions, so it is often not easy to use for photovoltaic power generation.

  Since solar power generation uses a solar panel, a stand for supporting it is required. There are various types of mounts, and many are supported on the ground with legs and piles. Also, there are some that fix the four corners of the pedestal with things like pins, but all of them are large to some extent. Therefore, the present invention considers the slope where the land cost is the cheapest and has not yet been noticed as the place of photovoltaic power generation as the primary place. The “Tagata mount” and “ladder mount” with the simple structure described below are designed to be installed even on slopes as the main mount.

  In addition, if this stand is installed, the sunlight is shielded, so that the grass does not grow. On the other hand, the slope is mowing regularly, but this is dangerous and expensive, but this grass protection effect can reduce this. By the way, each stand requires a wiring path for collecting current, but a portion where a solar panel with a predetermined width does not exist in a direction perpendicular to the maximum inclination line of the inclination, that is, a groove is formed, What is necessary is just to make this continue by each mount as a wiring groove. If the groove is left as it is, it can be covered with an openable / closable lid if it is exposed to sunlight or gets wet in the rain.

JP 2010-138630 A

  The present invention intends to install a solar panel by utilizing slopes and slopes that have not been conventionally used, and makes it easy and inexpensive to mount the solar panel, and can be installed efficiently. It is what I did.

  Accordingly, the present invention provides a cross frame made of a steel material having two linear portions extending in a cross shape around the center block in the gantry supporting the solar panel according to claim 1. The “Tagata mount” is made up of a square frame that is placed on a cross frame with steel materials wrapped around it, and the solar panel is supported by the square frame of the “Tagata mount” and fixed to the center block. It provides a solar panel gantry characterized in that the “Tagata gantry” is fixed on the ground by piercing it into the ground. In addition, as a modification, the frame is a frame for supporting a solar panel according to claim 7, and a “ladder-shaped frame” is formed by extending a plurality of horizontal beams over two or three or more vertical beams, A solar panel gantry is provided, characterized in that the solar panel is supported in a partitioned space in the “ladder-type gantry”.

  In the present invention, the “Tagata mount” is installed on a slope or a slope as described in claim 5 as an installation method for the former type of mount, and the “Tagata mount” is entirely grounded to the ground. As a method of installing the latter type of gantry, the “ladder type gantry” is arranged on a slope or a slope. At least the upper, middle, upper and lower ends of the “ladder-type mount” are grounded, a fixing block is attached to this part, and a fixing rod is inserted into this fixing block and inserted into the ground. The “ladder-type mount” is fixed.

  According to the first aspect of the present invention, since the cross frame positioned below has a linear portion on the light, even if there is unevenness on the ground, the cross frame extends straightly by being bitten or bridged. That is, almost no leveling is required, so it can be installed at low cost even on slopes. In addition, since a rectangular frame having steel material only on the periphery is placed on the cross frame positioned above, the entire frame (even if a solar panel is added) is very light. Therefore, as in claim 5, the center center block can be supported only by supporting it with a single fixing rod, and with this, labor and materials can be omitted, and installation can be made at low cost. In this case, the orientation of the gantry can be adjusted by changing the direction in which the fixing bar is inserted.

  The above-described rectangular frame is similar to the Chinese character “Ta” when viewed from above, and in this respect, this is referred to as a “Tagata mount”. If the “Tagata platform” is fixed on the ground by the above method, it will be shaped like a cocoon with an umbrella supported by a single shaft, making it very simple. On the other hand, since the thing of Claim 7 has a shape like a ladder, it is referred to as a “ladder-shaped mount”, which is also simple in structure, and according to the installation method as in Claim 9, It can be easily installed even on slopes with poor conditions. In both methods, the solar panels float from the ground and are not grounded in principle (including those that are partly in contact with the ground), so they do not get wet or become dirty with mud. In addition, it has a herbicidal effect because it is not exposed to sunlight under the frame.

It is a perspective view of the mount frame which consists of a cross frame and a square frame. It is a top view of a mount. It is XX sectional drawing of FIG. It is YY sectional drawing of FIG. It is a top view of the state which spread the mount. It is side surface sectional drawing of the state which covered the volt | bolt with the bag cap. It is the top view and side view of the gantry of another example. It is the top view and side view of the gantry of another example. It is a top view of the mount frame of another example. It is a partial top view of the mount frame of another example.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a side sectional view of a gantry A according to the present invention, FIG. 2 is a plan view, and FIG. 3 is a sectional view taken along the line XX in FIG. 2, but this gantry is installed on a slope facing south. The cross frame 1 is composed of a cross frame 1 and a quadrilateral frame 2. The cross frame 1 is literally a cross-section of steel materials. In this example, L-shaped steel with two flat bars and protruding pieces facing downward and outward. The rectangular frame 2 is formed of L-shaped steel with a protruding piece facing inward and upward in a square shape, and the inside is hollow. Then, the quadrangular frame 2 is fixed on the cross frame 1 (a steel material around the quadrangular frame 2 is welded to the end of the cross frame 1) to form a frame. In this regard, when this frame is viewed from above, it is shaped like a Chinese character “ta” and is characterized by a lot of space. Therefore, it is light and it is possible to put a foot into this space (before or after laying the solar panel), and laying and inspection work is easy. Both frames 1 and 2 are referred to as “Tagata mount” A.

  The size of the “Tagata mount” A is not limited, but about 1.9 m (half) square is suitable from the weight and shape, and handling is convenient. Moreover, the crossing board 3 which opened the hole 3a may be provided in the base near the edge part of the space between the two steel materials of the cross frame 1. FIG. This is because a pin is inserted into the hole 3a when installed to suppress positional deviation. A center block 4 is provided at the center of the gantry, that is, the center of the space between the two steel members (the cross frame 1, that is, the center of the “Tagata gantry” A). The center block 4 is fitted into this part from above and fixed by welding or the like. The shape, size, height, and the like of the center block 4 are not limited, but the height is preferably the same as that of the cross frame 1. In this example, the upper and lower surfaces are flush with the cross frame 1, and the hollow body is the center block 4.

  In the rectangular frame 2, a solar panel integrated group (hereinafter referred to as a solar panel 5) in which commercially available solar panels are uniformly stacked is placed on an inward protruding piece at the end of the rectangular frame 2. (Of course, fixing with fixing bolts etc.) Therefore, the solar panel 5 is usually provided so as to be lifted from the ground (not grounded), but when the “Tagata mount” A is provided to be inclined, it may be partially grounded. In this case, the solar panel 5 may employ two or four blocks. The two blocks are installed with a flat bar space (this is referred to as groove 6) between them, and the four blocks are the space between the groove 6 and the two L-shaped steels (this is this). Is set between the grooves 7). There is also a single solar panel 5, but in that case, a space for a fixing rod to be described later is secured at least in the center block 4.

  By the way, although the solar panel 5 requires the wiring 8 for collecting electricity, the groove | channel 6 is utilized in this example. That is, as shown in FIG. 3, the wiring 8 is provided in the groove 6. In this example, the wiring 8 is directly placed on the ground. However, it is usually preferable to insert a hook (not shown) and turn the wiring 8 in order to prevent damage and leakage. The reason why the groove 6 is used as a wiring groove is that the groove 6 is orthogonal to the maximum slope line of the slope, so that the wiring is continuous for a long time and the connection operation is convenient. In this case, since it is necessary to surpass rain dew, a lid 9 that can be opened and closed is provided. The lid 9 is fixed by a hinge 10 so that it can be opened outwardly in the grooves 6 on both sides with the center block 4 as a boundary. In addition, if the lid 9 is closed, naturally the sunlight does not hit and no grass grows in this part. In the case of a single solar panel 5, the groove 6 or the like does not exist, so the back surface or the like is used.

  The above-mentioned “Tagata mount” A supports the solar panel 5 and lays it on the ground, but the laying area is inclined or horizontal, and there is no limitation on the top and bottom and the length. However, there are many slopes, but if it is a mountain slope, it is necessary to cut some undergrowth. In the present invention, it is installed in a considerably large laying area on the slope facing south. FIG. 5 is a cross-sectional view taken along the line YY of FIG. 2. A fixing rod 11 is passed through the front and back of the center block 4, a screw portion 11 a formed thereon is passed through the hole 4 a, and a nut 12 is screwed and fixed. At this time, the length of the screw portion 11a may be about the height of the “Tagata mount” A (the lid 9 does not interfere as shown in FIG. 3). The fixing rod 11 may be pierced into the ground as it is, but in order to strengthen it, a pillar of concrete 13 may be formed around and embedded therein. When the “Tagata platform” A is supported in this way, it is just like a cocoon with an umbrella supported by a single shaft, which saves materials and makes installation and removal work very easy. It is also a feature.

  By the way, as described above, the “Tagata platform” A may be tilted separately from the angle of the slope so that sunlight can be received efficiently. In this case, the fixing rod 11 is inserted in a different direction. Adjustment of the direction and interval of the “Tagata platform” A is performed individually, but at a point where the topography does not change much, the same direction may be sufficient for a group of adjacent ones. However, if the neighboring object is shaded, it is in a bad condition, and the direction of the fixing rod 11 varies in a place where the unevenness of the lower slope is severe. In addition, depending on the tilt angle, a part of the ground will be grounded. In that case, the normal hip along the maximum slope line is usually grounded, but in some cases, the shoulder should be grounded. There is also.

 In any case, two or more points are grounded, and fixing (support) is more stable. In addition, if a model of the quadrangular frame 2 is prepared in advance, the tilt angle and the sticking direction of the fixing rod 11 are determined using the model, and then the real quadrangular frame 2 is installed, the laying is easier. become. On the other hand, although it is grass prevention, the optimum installation that maximizes the grass prevention function is to make the pedestal fully adhere to the ground, but it is impossible on the slope. However, a slight gap or the like has a sufficient herbicidal effect. In addition, by installing a weedproof sheet or the like (not shown) between the stands, it is possible to prevent a considerable area of the entire installation area.

 In this example, the end face of the rectangular frame 2 has a hinge 10 or the like and cannot be in close contact with the adjacent one, so that a spacer 14 is interposed therebetween. In addition, it connects with the L-shaped steel of an edge part with the simple connector 15 inserted from the top (connector 15 is not necessarily required). The use of the spacers 14 and the connecting tool 15 has an advantage that a group of “Tagata mounts” A can be integrated, and the effect of preventing the entire shift when receiving a large external force such as a storm is great. According to such an installation, the “Tagata platform” A, that is, the solar panel 5 substantially coincides with the inclination of the slope and becomes an appropriate angle.

  In this example, the groove 6 is the wiring groove as described above, but the lid 9 is opened and closed during maintenance or the like. In addition, according to this example, although the groove | channel 7 between L-shaped steel will be exposed, it is suitable to insert and cover the cover of the separate insertion / extraction type like clogs (illustration omitted). According to this, not only light shielding but also a person can ride on this, which is convenient for laying and maintenance. The work is performed by hanging a person in a robe and dropping it from above. At this time, if there is a place in the “Tagata mount” group A, the posture is more stable and the work is easy. By doing so, the amount of power generation suitable for the laying area is expected, and at the same time, the bottom of the gantry A is shielded from light so that it also has a weedproof function. In this respect, the larger the laying area, the higher the effect.

  By the way, since these screw part 11a and nut 12 are exposed to an open-air, there exists a possibility of corroding. Therefore, as shown in a partial side sectional view of FIG. 6, a screw washer 16 having a spherical surface 16a recessed on the upper surface through a threaded portion 11a on the center block 4 and a screw formed on the outer periphery is placed. A coupler-type nut 17 having a bottom surface formed on the spherical surface 16a and a screw for tightening the screw portion 11a in the center is fitted, and the screw portion 11a is tightened. Then, the bag cap 18 is put on the screw of the screw washer 16. According to this, the fixing rod 11 and the nut 12 are not corroded by rain dew. The spherical surface 16a of the screw washer 16 and the spherical surface 17a of the coupler type nut 17 are brought into contact with each other, so that the misalignment between the hole 4a and the fixing rod 11 is complemented.

  This “Tagata mount” A is stated to be installed on the slope, but the larger the installation area, the larger the power generation and the higher the herbicidal effect. In this case, it is suitable to use the groove 6 as a wiring groove as described above, but in this case, the wiring 8 must pass through the center block 4 as well. Therefore, a wiring hole 4b is made in this portion of the center block 4. FIG. 5 is a plan view in which the “Tagata mount” A is installed in a considerably large area and the solar panel 5 is installed. However, since the “Tagata mount” A and the solar panel 5 are not so heavy, they are continuously arranged. Even in the case of laying down, the fixed rods 11 may not be necessary for all “Tagata mounts” A. For example, the fixing rod 11 may be provided on every other “Tagata mount” A. However, since the “Tagata platform” A without the fixing rod 11 should not be moved by wind or the like, in this example, it is connected to the adjacent “Tagata platform” A by a simple connector 19.

  As described above, since the quadrangular frame 2 constituting the “Tagata mount” A is mounted on the cross frame 1 made of a thin plate surface, it slightly floats from the ground. Moreover, since the two flat bars of the cross frame 1 and the protrusions of the L-shaped steel are thin, they bite into a slight rise and bridge the upper side against a dent and pass straight. In this respect, ground leveling is not necessary, so the installation cost is low. Also, if there are large rocks that cannot be cut off on the ground, they will remain as they are in a quarter space block, and a spacer (not shown) that is long enough to cross them will be placed under the center block 4. And the rectangular frame 2 may be further raised.

  The above is a basic form, but the present invention may take various modified forms. For example, although it is the “Tagata mount” A, it may be an X shape instead of a cross, or a shape other than a quadrangle. However, it is preferable that there is a gap and is lightweight. One member, for example, a square lattice plate may be used. In this case, it is preferable to use a steel plate vertically for the reason described above. Furthermore, although the number of fixing rods is one, it may be two or more. However, if there are too many, it will take time for construction, so it is necessary to consider that point. Of course, the terrain can be flat.

  7 and 8 are a plan view and a side view of another example of the gantry, but in this example, the vertical beam 20 and the horizontal beam 21 are crossed into a cross to form a ladder. This is referred to herein as a “ladder-type mount” B. And the space by the vertical beam 20 and the horizontal beam 21 in a ladder is made into the rectangular frame 22 which supports the solar panel 5 (it does not drop in a bottom). In the case of this example, the upper and lower end portions are grounded to enhance the fixation, but only the upper end may be used, or it may be floated in the air. At least the upper end of the horizontal rail 21 is attached to the fixing block 23 instead of the center block 4, and the fixing rod 24 is inserted into the ground through the hole 23a and fixed. Although the size and shape of the rectangular frame 22 are not limited, for example, the width of the vertical beam 20 is 1.7 m, and the distance between the horizontal beams 21 (two in this case) is 0.9 m. . Since the “ladder-shaped mount” B in this example has a large area, even if there is a depression or a rock or earth protrusion on the way, only that depression or protrusion is sufficient.

  According to this, the rectangular frame 22 is 1.7 m × 0.9 m, and if it is set to an angle at which sunlight is received at a right angle, 240 W of power can be generated in fine weather. In addition, if the dimension of the vertical beam 20 is 6 m, five rectangular frames 22 can be taken. In addition, the thing of FIG. 8 attaches the fixing block 23 to the upper end and lower end of the crosspiece 21, and inserts the fixing rod 24 in each, and fixes both ends, and fixation is strengthened more. Note that the fixing rod 24 (and the fixing block 23) for fixing is not limited to the upper end. Also, two or more “ladder-type mounts” B may be connected in the vertical direction. In this case, the upper fixing block 23 at the lower end and the fixing block 23 at the upper lower end are overlapped, and one fixing rod 24 is inserted. If it is included, the structure is simple and cheap. Of course, the upper end and the lower end can be bent up and down and left and right around the fixing rod 24, so that the installation location is not restricted by the topography.

  FIG. 9 is a plan view of still another example. In this example, a number of vertical bars 21 are arranged side by side, and the intermediate interval is widened. The fixing rod 24 is inserted into the ground with fixing blocks 23 attached to the four corners of the upper and lower ends. However, when the four corners cannot be used, it may be fixed only by the fixing block 23 at the upper end, or the fixing block 23 may be attached somewhere in the middle. Further, the upper and lower connections are the same as described above. In this example, there is an advantage that a single “ladder-type mount” B can be laid in a wide area. In this "ladder-type mount" B, 25 240W units can be installed, and 6KW power generation is possible.

  Furthermore, what is shown in FIG. 10 is a case where the “ladder-type mount” B is extended, but the upper and lower meats at the lower end of the upper vertical rail 20 are shaved (only on the side surface) at the upper end of the lower vertical rail 20. Insert a core or the like and insert the core into the upper vertical rail 20 (this connection method is an example and is not limited to this, but the width of the vertical rail 20 can be the same) is there). According to this, the pin 25 can be bent up and down, and the desired “ladder-type mount” B can be extended as much as possible regardless of the terrain.

  By the way, whether it is the above-mentioned “Tagata mount” or “ladder-type mount”, the fixing rods 11 and 24 for fixing the same are assembled with scaffolding at the place, and workers are arranged here. Usually, it is based on the scaffolding method of working with a driving machine. However, recently, a scaffolding method that is often used may be used. The scaffolding method is characterized by the fact that the work cost can be reduced by standing a fence around the destination, carrying the above machine with a rope, etc., and suspending a person or machine with a robe. .
