Description

Cable support structure for photovoltaic solar panels}

The present invention, by connecting the photovoltaic panel arrays including a plurality of photovoltaic panels arranged in the transverse direction in the longitudinal direction by a connecting bar, ensures sufficient power generation efficiency while achieving stable dynamic characteristics and excessive shaking or vibration of the photovoltaic panel It is for a cable fixed solar panel support structure that can prevent.

Recently, as interest in the energy business using renewable energy resources has increased, interest in solar power, an eco-friendly energy resource, has been steadily increasing.

Photovoltaic power generation is a power generation method that directly converts sunlight into electrical energy using a solar cell. It has no merit of resource depletion and no pollution by not emitting environmental pollutants.

For such photovoltaic power generation, a solar cell, a storage battery, and a power conversion device are required.

Conventionally, a frame support structure as shown in FIG. 1 was used to support a solar panel constituting a solar cell (Registration Patent No. 10-1864438).

However, such a frame support structure is inefficient in terms of material utilization due to its complicated configuration. In addition, since there are many joints between members, the construction cost is high and the column spacing is tight, which is disadvantageous for utilization of the lower space. In addition, when installed on soft ground, warpage may occur in the frame and solar panels due to uneven settlement. As a result, the cost of the foundation or pile is excessive, such as the cost of the foundation construction being larger than that of the superstructure.

Accordingly, in order to improve the disadvantages of the frame support structure as described above, a technology for a cable support structure supporting a solar panel by a cable as shown in FIG. 2 has been developed (Registration Patent No. 10-1273292).

The cable support structure has advantages of low material consumption, simple construction of the joint, and little influence on the solar panel due to uneven settlement.

However, there are many shakes caused by wind, and there is a risk of collapse due to divergent vibration, that is, flutter.

In addition, the load is concentrated on the solar panels on the front side, which are directly affected by the wind load, causing excessive horizontal force in some posts, and horizontal movement, that is, sway, occurs unevenly.

In order to solve these problems, it is possible to minimize the influence of wind by installing a solar panel horizontally to the ground, or consider a method of preventing a sway by hanging a separate suspension cable.

However, when the solar panel is horizontally installed, the power generation efficiency is greatly reduced as the incident angle of the solar light changes, and if a separate suspension cable is installed, unnecessary space is required and the utilization of the land is reduced.

In addition, since the anchor cable 414 for supporting the load of the solar panel must be extended to the outside of the end column 420, this also has a problem of deteriorating the utilization of the site.

In order to solve the above problems, the present invention supports a cable-mounted photovoltaic panel capable of reducing the effects of vibration and wind load of the photovoltaic panel while securing sufficient power generation efficiency while mounting and supporting a plurality of rows of photovoltaic panels on a cable. I want to provide structure.

The present invention is to provide a cable-mounted solar panel support structure that can fully utilize the site by minimizing the portion protruding outside the support structure for supporting the solar panel.

Being an intermediate prop; It provides a cable fixed solar panel support structure, characterized in that consisting of.

The present invention according to another preferred embodiment provides a cable-fixed solar panel support structure characterized in that the intermediate struts located on the same line in the longitudinal direction are interconnected by a support bar connecting a plurality of intermediate struts.

According to the present invention has the following effects.

First, the main pillar of the photovoltaic panel array in which a plurality of inclined photovoltaic panels are disposed in the transverse direction is fixed to the ground at both ends of the photovoltaic panel array to support a pair of cables on which the photovoltaic panel is mounted. Therefore, it is possible to realize a large span soy due to the cable support structure, and it is possible to reduce the construction load by reducing the load on the foundation and secure the open feeling of the lower space. In addition, since the solar panels are inclined, sufficient power generation efficiency can be secured, and there is no damage due to uneven settlement of the main prop.

Second, since the connecting bar connects the entire photovoltaic panel arrays in the longitudinal direction, the wind load can be evenly distributed to the entire photovoltaic panel array. Accordingly, it is convenient to design and construct all the solar panel arrays of all columns by designing and constructing them at the same level. In addition, a plurality of rows of photovoltaic panel arrays are connected to each other to synchronize their behavior, thereby realizing stable dynamic characteristics to prevent excessive shaking or divergent vibration of the photovoltaic panel.

Fifth, since the cable can be supported by the main support composed of the compression support member and the tension support member, there is no portion protruding outward of the main support. Accordingly, it is efficient because it can be used as far as possible near the boundary of the site.

3 to 6, in the cable fixed solar panel support structure of the present invention, a solar panel array 1 in which a plurality of solar panels 10 inclined to one side is disposed in the horizontal direction is vertically arranged. It is provided with a plurality of rows, each of which is fixed to the ground at both ends of the pair of main posts 11, the upper cable 12 and the lower cable 13 and the upper cable (12) connecting the pair of main posts (11) 12) and the photovoltaic panel array (1) consisting of the photovoltaic panel (10) in which a plurality of pieces are horizontally mounted on top of the lower cable (13); Connecting the lower cable 13 in the longitudinal direction across the plurality of rows of solar panel arrays 1, the connecting bar 21 supporting the tension and compressive force and one end coupled to the upper cable 12, the other end A support frame (2) composed of a support bar (22) coupled to the connection bar (21); And a cable fixing member 172 that is fixed to the ground by being coupled to the upper end of the support body 171 and the support body 171 in the longitudinal direction, so that the upper cable 12 and the lower cable 13 surround the outer circumferential surface and are fixed. It is composed of at least one intermediate post (17) provided between the pair of main posts (11); It is characterized by consisting of.

In the present invention, in the photovoltaic power generation structure including the plurality of rows of photovoltaic panels 10, the photovoltaic panels 10 are supported while supporting the photovoltaic panels 10 by cables 12 and 13 but securing sufficient power generation efficiency. ) To provide a cable fixed solar panel support structure that can reduce vibration and wind load.

In the cable fixed solar panel support structure of the present invention, a plurality of solar panel arrays 1 in which a plurality of solar panels 10 inclined to one side are disposed in the horizontal direction are provided in the longitudinal direction.

The photovoltaic panel array 1 is configured by arranging a plurality of photovoltaic panels 10 inclined to one side in a horizontal direction.

Each solar panel 10 is arranged to be inclined to one side so as to sufficiently receive the incident angle of sunlight.

A plurality of such solar panel arrays 1 are provided in the longitudinal direction.

In the present invention, the east-west direction is based on the northern hemisphere, and the north-south direction is described as the longitudinal direction.

Accordingly, the solar panel 10 may be arranged to be inclined in the longitudinal direction to face south.

The inclination angle of the solar panel 10 is preferably set in a range of 10 to 30 °, and more preferably configured in a range of about 20 °.

The solar panel array 1 includes a main post 11, an upper cable 12 and a lower cable 13, and a solar panel 10.

The main post 11 is provided with a pair so as to be located at both ends of the solar panel array (1).

The lower end of the pair of main pillars 11 are respectively fixed to the ground at both ends of the solar panel array 1.

The upper cable 12 and the lower cable 13 connect a pair of main posts 11.

Accordingly, the main post 11 is fixed to the ground at both ends of the solar panel array 1 to support a pair of cables 12 and 13.

The pair of cables 12 and 13 are arranged to be spaced apart from each other, and can be arranged to have a height difference according to the inclination angle of the solar panel 10.

Since the cables 12 and 13 are not affected by the relative displacement, there is no damage due to uneven settlement of the main prop 11.

In the present invention, since the cable support structure is adopted for the support of the solar panel 10, it is possible to realize a large span compared to the frame support structure. Therefore, it is possible to reduce the construction cost by reducing the load on the foundation, and increase the open feeling of the lower space.

The photovoltaic panel 10 is mounted in a plurality in the transverse direction on the upper portion of the upper cable 12 and the lower cable 13.

The lower cable 13 of the solar panel array 1 includes a support frame 2 including a connecting bar 21 connecting the lower cable 13 in the longitudinal direction across a plurality of rows of solar panel arrays 1. ).

Normally, a large load is applied to the solar panels 10 of the solar panel array 1 disposed at the foremost or rearmost side by the wind load. Therefore, these solar panel arrays 1 must be designed to be stronger than other solar panel arrays 1.

However, in the present invention, by connecting the entire solar panel array 1 in the longitudinal direction with a connecting bar 21, it is possible to distribute the wind load evenly to the entire solar panel array (1). Accordingly, it is convenient to design and construct the solar panel array 1 of all rows by designing the same level and constructing the same.

In addition, the connecting bar 21 connects a plurality of rows of solar panel arrays 1 to each other to synchronize their behavior. Accordingly, stable dynamic characteristics can be realized to prevent excessive shaking or divergent vibration of the solar panel 10.

To this end, the connecting bar 21 is preferably formed of a member capable of supporting both tensile and compressive forces.

The connecting bar 21 may use a lightweight steel frame with an open cross-section, such as C-shaped steel, for weight reduction.

The connecting bar 21 does not directly support the solar panel 10 but is coupled to the lower cable 13 between the solar panels 10.

In the present invention, the wind load is evenly distributed to the solar panel array 1 of a plurality of rows by the connection bar 21. Accordingly, uneven sway can be prevented, and rope tension and point reaction force can be reduced.

In addition, since the behavior of the solar panel array 1 of a plurality of columns is synchronized with each other for sway and rotational displacement, it is possible to prevent excessive shaking and divergent vibration of the solar panel 10 by implementing stable dynamic characteristics.

In addition, the simple structure makes it possible to simplify materials and maximize economic efficiency by minimizing the number of parts.

As shown in FIGS. 5 and 6, the support frame 2 may further include a support bar 22 having one end coupled to the upper cable 12 and the other end coupled to the connection bar 21. have.

Basically, when the lower cables 13 of a plurality of rows are connected in the longitudinal direction by the connecting bar 21, the lateral load can be efficiently and evenly distributed. However, in this case, the photovoltaic panel 10 itself in each row rotates around the lower cable 13, so that the photovoltaic panel 10 may be shaken.

Accordingly, the support frame 2 is configured to further include the support bar 22.

Therefore, one end of the support bar 22 is fixed to the upper cable 12 of each column of the solar panel array 1, and the other end of the support bar 22 is coupled to the connection bar 21 to thereby perform the solar panel 10 ) Can control the rotational displacement.

The support bar 22 may be formed to be inclined upward to the front side to support the rear of the solar panel 10 by axial force, and may be arranged to face the vertical direction.

7 is a perspective view showing a deployment state of the fixing clip, and FIG. 8 is a perspective view showing a coupling relationship between the fixing clip and the cable.

7, the upper cable 12 and the lower cable 13 are fixed to the upper end and the lower end of the solar panel 10 by a fixing clip 14, respectively, the fixing clip (14) is formed in the center of the other side of the first fixing plate 141 and the first fixing plate 141 having a cutout portion 142 formed at one center, and is bent toward the first fixing plate 141 to the cutting portion 142 Consists of a second fixing plate 143 to be inserted, the first fixing plate 141 and the second fixing plate 143 are fixed to the side ends of the solar panel 10 by fastening members, and the cables 12, 13 The second fixing plate 143 may be configured to be fixed to the inside of the bent portion.

The upper cable 12 and the lower cable 13 should be spaced apart from each other as much as possible to improve the resistance to wind. Accordingly, the upper cable 12 and the lower cable 13 can be fixed to the upper and lower sides of the solar panel 10 by using the fixing clips 14.

The fixing clip 14 is composed of a first fixing plate 141 on one side and a second fixing plate 143 on the other side, and can be manufactured by cutting and bending an iron plate.

The second fixing plate 143 is bent to be inserted into the cutout portion 142 formed at the center of one side of the first fixing plate 142.

When the second fixing plate 143 is bent, it is preferable to bend the ends of the first fixing plate 141 together so that the cables 12 and 13 can be fixed over a relatively wide width.

The cables 12 and 13 are inserted into and fixed inside the bent second fixing plate 143.

When the cut-out portion 142 is formed in the same shape and size as the second fixing plate 143, material loss during manufacturing of the fixing clip 14 can be minimized.

Since the first fixing plate 141 and the second fixing plate 143 have some elasticity, the first fixing plate 141 and the second fixing plate 143 are opened and fixed by inserting cables 12 and 13 inside the bend. The clips 14 and cables 12 and 13 can be coupled to each other.

At this time, the construction method is a fastening member such as a bolt or a screw to the first fixing plate 141 and the second fixing plate 143 of the fixing clip 14 while the fixing clip 14 is first fitted to the cables 12 and 13. It can proceed in the order of fixing to the frame side end of the solar panel 10.

Alternatively, the first fixing plate 141 of the fixing clip 14 is fixed to the side of the frame outside the solar panel, and the cables 12 and 13 are inserted by opening the first fixing plate 141 and the second fixing plate 143. After that, the second fixing plate 143 may be fixed to the frame side end of the solar panel as a fastening member.

Alternatively, before bending the second fixing plate 143, fix the first fixing plate 141 of the fixing clip 14 to a frame side of the solar panel with a fastening member such as a bolt or a screw, and then connect the cables 12, 13 It is located on the front of the fixing clip (14). Then, the second fixing plate 143 is bent 180 ° toward the cutting portion 142 to be inserted into the cutting portion 142, and then the second fixing plate 143 is fixed to the frame side end of the photovoltaic panel with a fastening member and the cable ( 12, 13) can also be fixed.

The fastening member may be a bolt, a screw or the like.

The first fixing plate 141 and the second fixing plate 143 may be formed by pre-forming a fastening hole 144 into which a fastening member is inserted.

As described above, when the cables 12 and 13 are fixed by the fixing clip 14, the configuration is simple and the material cost is reduced. In addition, since the upper cable 12 and the lower cable 13 can be easily fixed to the solar panel 10, the workability is excellent.

Fig. 9 is a front view showing the coupling details of the main post, and Fig. 10 is a perspective view showing the coupling relationship between the cable fixing member and the cable of the main post.

9 and 10, the main support 11 is provided in the longitudinal direction, the upper cable 12 and the lower cable 13 is fixed to the cable fixing member 111, the cable fixing member ( 111) is coupled to the lower portion of the compression support member 112 to support the compression force and the cable fixing member 111 and the compression support member 112 is configured to have a predetermined angle with the compression support member 112 It can be configured as a tensile support member 113 to support the tensile force.

The main support 11 may be composed of a cable fixing member 111, a compression support member 112 and a tension support member 113.

Here, the cable fixing member 111 may be provided in the longitudinal direction, the compression support member 112 and the tension support member 113 in the transverse direction.

The cable fixing member 111 is provided in the longitudinal direction, and the upper cable 12 and the lower cable 13 are fixed.

The cable fixing member 111 may be configured to be inclined to correspond to the inclination angle of the solar panel 10.

The compression support member 112 is coupled to the lower portion of the cable fixing member 111 to support the compression force.

The compression support member 112 may be arranged such that the lower portion is inclined in the transverse direction.

The tensile support member 113 is coupled to the nodes of the cable fixing member 111 and the compression support member 112, and is configured to have a predetermined angle with the compression support member 112 to support the tensile force.

The compression support member 112 and the tension support member 113 may form a truss to support the lateral force by the cables 12 and 13.

The tensile support member 113 may be arranged such that the lower portion is inclined outward in the lateral direction, but may be configured to be perpendicular to the ground so that there is no portion protruding outward from the cable fixing member 111.

In this case, by installing a support bar 18 on the outside of the tension support member 113 to interconnect the plurality of main posts 11, it is possible to resist the longitudinal bending moment occurring in each main post 11 have.

In the conventional method of fixing the cable by fixing it to the anchor, the distance between the anchor and the pillar must be quite spaced, so the length of the extension of the cable to the outside of the pillar is long and requires a lot of space. Accordingly, there is a disadvantage that the efficiency of using the land decreases.

However, in the present invention, since the cables 12 and 13 are supported only by the main post 11 made of the compression support member 112 and the tension support member 113, space is not required outside the main post 11. Accordingly, it is efficient because it can be used as far as possible near the boundary of the site.

10, the upper cable 12 and the lower cable 13 can be fixed by winding each end around the cable fixing member 111.

To this end, the cable fixing member 111 may be provided with a fixing ring 114 for fixing the positions of the cables 12 and 13.

Therefore, fixing the cables 12 and 13 is very simple and economical.

The helical pile 16 is a helical rotating plate coupled to the outer circumferential surface of the shaft, and is a pile that exhibits not only compressive load support but also strong support against tensile force.

Since the helical pile 16 can be constructed by rotational rotation, there is no embedding, noise and vibration. It is also easy to construct inclined.

Thus, if the compression support member 112 and the tension support member 113 are directly supported by the helical pile 16 capable of supporting both the compression force and the tensile force, there is no need for a concrete foundation structure for existing cable anchoring. Accordingly, it is possible to greatly simplify the basic construction, thereby reducing construction costs, and simplifying construction and management by simplifying material types.

The helical pile 16 may be placed about 4m in the ground, and the main prop 11 can be sufficiently supported by installing a single file without additional joints.

When the helical pile 16, which is a deep pile, is used, an effect of reducing inequality can be obtained.

The helical pile 16 is preferably compressed into the ground at the same angle as the compression support member 112 and the tension support member 113, respectively.

Accordingly, the compression support member 112 and the tension support member 113 can transmit the load to the helical pile 16 only by the axial force.

A joint plate 161 may be integrally provided on the upper end of the helical pile 16. And the compression support member 112 and the tension support member 113 may be provided with a bonding plate 115 at the bottom, respectively.

Accordingly, the bonding plates 161 and 115 that face each other can be fixed by bolts or welding to join each member.

11 is a perspective view showing an intermediate strut supporting the upper and lower cables.

As illustrated in FIG. 11, between the pair of main posts 11, at least one intermediate post 17 supporting the upper cable 12 and the lower cable 13 may be provided.

Accordingly, the position of the upper cable 12 and the lower cable 13 is fixed to the cable fixing member 172 by frictional force, and displacement of the upper cable 12 and the lower cable 13 is allowed to some extent.

Therefore, even when a large tension acts on the upper cable 12 and the lower cable 13, it is possible to relieve the load with the cables 12 and 13 of the neighboring span.

In addition, it is possible to fix the upper cable 12 and the lower cable 13 without a complicated fixing member, so the coupling details and construction are simple.
