Description

  The present invention relates to a solar power module mounting system used for installing a solar power generation module.

  In order to install a solar power generation module, it is often installed on a frame in which a steel frame is assembled. Since the photovoltaic power generation module fixed to the steel frame frame is greatly affected by the wind, it is necessary to firmly fix the frame. Therefore, a means for driving the anchor bolt into the installation position and fixing the gantry is employed. However, when the installation position of the photovoltaic power generation module is on the roof, the anchor bolt is driven to cause a crack in the waterproof layer on the roof, resulting in a problem of rain leakage.

  Further, a fixing means using a weight instead of the anchor bolt is employed. As this weight, for example, a frame is fixed to a concrete block or the like. By using such a weight, the anchor bolt or the like can be fixed without being driven.

  Furthermore, the gantry described in Patent Documents 1 and 2 uses the gantry itself as a weight. This gantry relates to a gantry in which a solar power generation module is assembled in advance, and in the installation work, the solar power generation module is transported and installed together with the gantry.

  According to the conventional gantry, there is a disadvantage that the waterproof layer on the roof is cracked by using the anchor bolt. In addition, if a weight such as a block is used on the roof, the load on the roof will be extremely heavy, and in existing buildings where solar power generation modules are not planned to be installed in advance, the durability should be insufficient. There is also a risk that it will not be possible.

  Furthermore, as described in Patent Documents 1 and 2, when a weight base is installed on the roof, the load on the roof becomes extremely heavy, so that not only a problem occurs in durability, but also a state where a photovoltaic power generation module is assembled in advance. Therefore, heavy machinery is indispensable for this installation work. Therefore, there is an inconvenience that the work cost becomes very large due to the large-scale transportation such as transporting heavy machinery and securing the crane movement range for the solar power generation module installation work. In addition, the number of high-rise buildings is increasing year by year, and it is becoming increasingly difficult to carry the work using heavy equipment on the high-rise building roof.

  Therefore, the present invention was created to solve the above-mentioned problems, and it is possible to rationalize the installation work with a light weight, and furthermore, it is a light that can be installed with high stability against strong winds while being lightweight. The purpose is to provide a power generation module gantry system.

In order to achieve the above-mentioned object, the first means of the present invention is to install one or a plurality of power generation modules P in a state where the light receiving surface is inclined on the gantry 10 that is placed on the installation surface by combining the frames. The gantry system is configured to form a cover body 20 that covers a gap opened from the periphery of the inclined power generation module P to the installation surface, and to mount the cover body 20 so as to be inclined outward from the periphery of the power generation module P. The gantry 10 is provided with a foundation frame 11 arranged in parallel to the horizontal installation surface, a linking frame 12 that supports the power generation module P and connects the foundation frames 11, and a power generation unit provided behind the foundation frame 11. And a support frame 13 that supports the rear end portion of the module P, and the cover body 20 is inclined to the outside from the side surface of the power generation module P and extended toward the horizontal installation surface. With a 21, and a rear surface cover 22 is inclined from the rear surface of the power generation module P outward extended toward the horizontal installation surface, configured to power generation module P is pressed against the installation surface by a wind pressure blowing the power generation module P It is to have done.

The base frame 11 of said frame 10 of the second means, upflow Ri preventing piece protrudes before and after the power generation module P that is placed on the cradle 10, the power generation module P is prevented from being blown up with your gantry 10 11A.

  In the gantry 10 of the third means, the width of the support frame 13 is formed to be a width on which the left and right ends of the power generation modules P in parallel are placed, and the two power generation modules are mounted on the support frame 13. The left and right ends of P are configured to be mounted simultaneously or one power generation module P and the cover body 20 are mounted at the same time, and the power generation module P is either in a single state, in parallel or in a column state on the gantry 10 Or a combination of parallel and column.

The fourth means is constructed such that a weather resistant rubber is laid between the gantry 10 and the horizontal installation surface, and the gantry 10 is placed on the weather resistant rubber.

The fifth means is to apply a waterproof caulking agent to the horizontal installation surface and to adhere the mount 10 placed on the caulking agent with the caulking agent. Means.

As in claim 1 of the present invention, by forming the cover body 20 covering the gap from the side surface of the power generation module P installed on the gantry 10 to the installation surface, and mounting the cover body 20 around the gantry 10, It is possible to reduce the lift applied to the power generation module P by suppressing the inflow of wind under the gantry 10 and to make the wind pressure blown to the power generation module P press the power generation module P against the installation surface. As a result, installation that is extremely stable against strong winds while being lightweight is possible. Moreover, since the present invention assembles and uses lightweight members, the installation work can be streamlined. Furthermore, the structure of the gantry 10 is a gantry 10 that is extremely simplified. Therefore, transportation and assembly work are facilitated, and the power generation module P can be easily installed even on the roof of a high-rise building. In addition, since the present invention can be installed in an extremely light weight, it is possible to install an existing building without a plan to install a solar power generation module in advance without worrying about load resistance .
Further, since the side cover 21 and the rear cover 22 are provided as the cover body 20, the wind pressure blown to the power generation module P is converted into an efficient force that presses the power generation module P against the installation surface. As a result, it is possible to perform installation that is lightweight but extremely stable against strong winds, and it is not necessary to use anchor bolts as in the past .

  As in claim 2, the base frame 11 is provided with a blow-up preventing piece 11 </ b> A that protrudes forward and backward of the power generation module P placed on the gantry 10 and prevents the power generation module P from being blown up together with the gantry 10. By providing this, the rising prevention piece 11A enhances the stability of the gantry 10. Therefore, even when strong wind blows from the front, rear, left and right of the power generation module P, the power generation module P is peeled off from the installation surface together with the gantry 10. There is no fear.

  According to claim 3, the power generation module P is configured to be mounted on the support frame 13 of the frame 10 of the present invention at the same time, or the power generation module P and the cover body 20 are simultaneously mounted. Or since it installs in the state of either parallel or a column, or the state which combined the parallel and the column, the arbitrary number of power generation modules P can be installed according to the breadth and shape of an installation position.

As described in claim 4 , by installing a weather resistant rubber between the gantry 10 and the horizontal installation surface and placing the gantry 10 on the weather resistant rubber, the horizontal installation surface such as a rooftop is not damaged. Can be installed. As a result, even when the waterproof layer is provided on the horizontal installation surface, the power generation module P can be installed without causing slight damage to the waterproof layer.

By applying a waterproof caulking agent to a horizontal installation surface and adhering the gantry 10 placed on the caulking agent with the caulking agent as in claim 5 , The installation surface can be integrated and a high waterproof effect can be obtained. In addition, the adhesive force of the caulking agent is added to the pressing force of the power generation module P by the wind pressure, thereby exhibiting a firmer fixing force.

  As described above, according to the present invention, it is possible to rationalize the installation work with a light weight, and to realize an object such that the installation can be extremely stable against a strong wind while being lightweight.

  Hereinafter, an embodiment of the system of the present invention will be described. The gantry system of the present invention is a gantry system in which the solar power generation module P is installed on a rooftop or other horizontal installation surface. The basic configuration of this gantry system is composed of a gantry 10 combined with a frame and a cover body 20 attached to the gantry 10 (see FIG. 1).

  The gantry 10 is formed of a metal material such as iron, aluminum, and stainless steel, or a synthetic resin material such as reinforced plastic, and includes a base frame 11, a connection frame 12, and a support frame 13 (see FIG. 3).

  The base frame 11 is a pair of members arranged on the left and right on the horizontal installation surface, and the connecting frame 12 connects the tip of the base frame 11. The base frame 11 is provided so as to protrude before and after the power generation module P placed on the gantry 10, and the protruding portion is used as a blow-up preventing piece 11 </ b> A, so that the power generation module P is blown up together with the gantry 10. Can be prevented (see FIGS. 1 and 2).

  The connection frame 12 is a member that supports the front end portion of the power generation module P while connecting the front end portion of the base frame 11 (see FIGS. 2 and 4). The connecting frame 12 in the illustrated example is configured so as to close the gap between the front end portion of the power generation module P and the installation surface.

  The support frame 13 is a member that supports the rear end of the power generation module P on the rear upper surface of the base frame 11 (see FIG. 4). And the width | variety of the support frame 13 is formed in the width | variety which mounts the left-right edge part of the two power generation modules P of a parallel state simultaneously. A pair of the power generation module P or the power generation module P and the cover body 20 are attached to the support frame 13 at the same time. The power generation module P is supported by the support frame 13 with the light receiving surface inclined. The inclination angle of the power generation module P by the support frame 13 can be freely set, for example, horizontally, 5 degrees, 10 degrees, 20 degrees, and the like. It is possible to set the angle at which the so-called down force that is pressed is used to the maximum extent.

  On the other hand, since the foundation frame 11 has a structure that is simply placed on the horizontal installation surface, the installation state of the power generation module P can be arbitrarily changed by changing the number and length of the foundation frames 11. For example, when a pair of basic frames 11 are installed on the horizontal installation surface, one power generation module P can be installed (see FIGS. 5 to 7). In this way, when the single power generation module P is mounted on the gantry 10, the side cover 21 closes the gap generated at both ends of the power generation module P.

  Moreover, when installing the 2nd power generation module P in series, two power generation modules P can be arrange | positioned forward and backward only by extending the length of a pair of base frame 11 (refer FIG. 8). . On the other hand, when the second power generation module P is installed in parallel, the three basic frames 11 are arranged in parallel, and the power generation module P is installed thereon (see FIGS. 9 to 11). Moreover, as shown in FIG. 9, by adjusting the number and length of the basic frames 11, a plurality of power generation modules P can be installed in a parallel and column combination state.

  The cover body 20 is formed of a metal material such as a highly corrosion-resistant plated steel plate, a galvanium steel plate, iron, aluminum, stainless steel, or a synthetic resin material such as reinforced plastic, from the side surface of the power generation module P installed on the gantry 10 to the installation surface. It is a member that covers the gap. The illustrated cover body 20 further includes a side cover 21 and a rear cover 22 (see FIG. 1). The side cover 21 is a cover inclined outward from the side surface of the power generation module P and extended toward the horizontal installation surface (see FIG. 2), and the rear cover 22 is inclined outward from the rear surface of the power generation module P and installed horizontally. It is the cover extended toward the surface (see FIG. 1). By attaching these cover bodies 20 to the periphery of the gantry 10, the inflow of wind under the gantry 10 is suppressed to reduce the lift applied to the power generation module P, and the wind pressure blown to the power generation module P is reduced by the power generation module P. Is pressed against the installation surface.

  The assembly procedure of the system of the present invention is as follows (see FIG. 3). First, a plurality of basic frames 11 are arranged in parallel on the left and right of the horizontal installation surface. Next, the leading ends of the basic frames 11 are connected by the connecting frame 12. Further, a support frame 13 is erected on the rear upper surface of the base frame 11. Then, the power generation module P is supported and fixed on the connection frame 12 and the support frame 13 (see FIG. 4). At this time, when a plurality of power generation modules P are connected in parallel, the ends of the two power generation modules P are placed and fixed on the support frame 13 (see FIG. 9).

  Subsequently, a cover body 20 that covers the gap from the side surface of the power generation module P installed on the gantry 10 to the installation surface is mounted around the gantry 10 (see FIG. 1). By covering the gap formed on the side surface of the power generation module P with the cover body 20 in this manner, the wind pressure sprayed on the power generation module P is converted into a pressing force that fixes the power generation module P to the installation surface.

  At this time, by laying weather resistant rubber between the gantry 10 and the horizontal installation surface, the stability of the gantry 10 can be improved and the roof surface can be protected. Further, instead of this weather-resistant rubber, a waterproof caulking agent may be applied to the horizontal installation surface, and the mount 10 placed on the caulking agent may be bonded with the caulking agent. Furthermore, it is also possible to use an anchor bolt as an auxiliary fixture depending on the situation.

  In addition, each structure of this invention is not limited to the example of illustration, In the range which does not change the summary of this invention, it can change freely.

  According to the present invention, it is suitable for installation mainly on a horizontal installation surface such as a rooftop of a building, but in addition to this, the power generation module P can be installed in any place such as use on the ground.
