Description

[0001] Structures for solar panel installation [

The present invention relates to a structure for mounting a solar panel on the ground, and more particularly, to a structure capable of minimizing the airflow required for installing a solar panel, The present invention relates to an installation structure for a solar panel, which is equipped with a function of cleaning a solar panel.

Solar panels use solar energy to produce electricity in the form of plates in which a number of cells form one module. Such a solar panel is installed together with the structure on the roof or mountain slope of a building having excellent solar radiation conditions. That is, the structure for installing the solar panel is generally composed of a column that is set up at a predetermined height from the ground, and a support frame that is assembled horizontally with respect to the columns to fix the solar panel.

Here, the solar panel is directly exposed to the sunlight, and due to wind, dust, and rain or snow, various foreign substances adhere to the surface. That is, when foreign matter adheres to the surface, there is a problem that the amount of light incident on the solar panel is reduced and the power generation efficiency is lowered. Conventionally, the cleaning of the photovoltaic panel depends on only a manual operation depending on a certain period or condition, so that waste of manpower and time is serious. Therefore, there is a trend toward more efficient cleaning of the solar panel.

For example, Korean Patent Registration No. 10-1116706 entitled " Cleaning Panels of Solar Panels ", Korean Patent Registration No. 10-1033443, " Photovoltaic Panel Cleaning Device of Photovoltaic Generators ", Korean Unexamined Patent Publication No. 10-2013-0124660 Korean Unexamined Patent Application Publication No. 10-2014-0129740 "Solar Cell Module Cleaning Device ", Korean Patent Registration No. 10-1367247" Solar Panel Cleaning Device ", Korean Registered Patent Gazette 10-1451288 "Photovoltaic Panel Cleaning Device ", Korean Patent Registration No. 10-1417992" Photovoltaic Panel Cleaning and Cooling Device ".

The proposed cleaning system consists of a bogie that travels back and forth to the structure that installs the solar panel, and a nozzle that injects washing water into the solar panel on the bogie. And a plurality of motors and guides for moving the bogie. Therefore, by removing the foreign matter on the surface with the washing water sprayed while the bogie reciprocates on the solar panel, the manpower and time required for washing can be minimized.

However, since the motor for moving the bogie and the pump for spraying the washing water must be operated at the same time, the energy required for the washing is considerable. Particularly, when the solar panel is installed on a large scale, there is a problem that energy consumed increases exponentially. That is, there is an ineffective closed end where the energy consumed for foreign matter removal is significantly higher than the power generation efficiency deteriorated by the foreign matter attached to the solar panel.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention relates to a structure for installing a solar panel SP on the ground, and is a solar panel installation structure having a support 10, a cleaning part 20 and an operation part 30 as main components as shown in Fig. 1 . The present invention has a function of automatically cleaning a solar panel (SP) with only a small amount of energy, together with a structure capable of doubling the clamping force while minimizing the airflow required for installing the solar panel (SP) do.

The supporting part 10 according to the present invention is a structure which is constructed so that a plurality of solar panels SP can be arranged from the ground as shown in FIG. 1 and includes a column 11, a support 12, 15 and outer and inner brackets 17, 18, respectively.

The column 11 is vertically fixed to the concrete laid on the ground so as to support the solar panel SP apart from the ground. The column 11 has a height at which the solar panel SP can be inclined at an angle suitable for the incidence angle of sunlight. The support 12 is horizontally mounted on the upper end of the column 11 to guide the plurality of mounts 15 to be mounted. Here, the column 11 and the support base 12 may be fastened with balls and nuts, and may be integrally welded in some cases.

The shelf 15 is formed in a shape of a cross-shaped profile bent to have a length enough to accommodate one or more solar panels SP, and is mounted so as to have a width to mount the solar panel SP on the top of the support table 12 do. An outer bracket 17 and an inner bracket 18, which press and fix the solar panel SP, are mounted on the upper end of the mounting table 15 with balls and nuts.

3A, the shelf 15 is bent in a cross shape so as to have a slot 15a into which the solar panel SP can be inserted at both ends thereof, and the outer bracket 17 is attached to the outer side of the solar panel SP and the inner bracket 18 is bent into a T shape so as to simultaneously press a pair of inner solar panels SP as shown in FIG. 3C.

That is, it is not formed through separate processing or welding, but is formed integrally by bending a plate material, so that it is easy to manufacture and has excellent durability. The solar panel SP is horizontally inserted into the slot 15a of the mounting table 15 while the outer and inner brackets 17 and 18 are assembled to the upper end of the mount 15, Reassemble the brackets (17) and (18) to complete the installation. Therefore, the fastening and fastening can be doubled while minimizing the number of mounting with the custom-made brackets 17 and 18 as well as being quick and convenient to install by the slot 15a.

The cleaning unit 20 according to the present invention removes foreign matter adhering to the surface of the solar panel SP and comprises a spray tube 21 and a nozzle 25 as shown in FIG. A connection port is formed at one end of the spray tube 21, and the washing water flows from the outside. The spraying tube 21 is installed at a predetermined distance from the upper end of the solar panel SP across the holder 15 in cooperation with the operation part 30 to be described later. Here, the outer surface of the spray tube 21 has a plurality of nozzles 25 for spraying the washing water flowing into a position facing the solar panel SP. The nozzle 25 switches the washing water to be sprayed at a high pressure so that the foreign matter adhering to the solar panel SP is removed.

At this time, the spray tube 21 integrally includes a plurality of nozzles 25 arranged in a row on the outer circumference and a rotary shaft 21a for sealing both ends so that the washing water is simultaneously branched. The rotary shaft 21a serves to close both ends of the spray tube 21 and to induce rotation so as to switch the spray angle of the nozzle 25 in conjunction with the operation part 30. [ The reason for switching the spraying angle of the nozzle 25 will be explained together with the operation part 30 described later.

1 and 2, the pair of operating parts 30 according to the present invention moves the cleaning part 20 so that the entire solar panel SP installed on the supporting part 10 can be cleaned, 4, a flow plate 31, an engagement plate 32, and a control plate 35 are provided.

The flow plate (31) moves along the holder (15) by the driving force of washing water sprayed to both ends of the spray tube (21). That is, the flow plate 31 has a plurality of rollers 31a that rotate in engagement with the slots 15a of the cradle 15. [ Here, it is preferable that the flow plate 31 has a shape that minimizes the weight while having sufficient strength to support the cleaning portion 20. [ The stopper plate 32 is attached to both ends of the holder 15 to prevent the flow plate 31 from being separated.

The control panel 35 interlocks with the engagement plate 32 on the inside of the flow plate 31 to switch the direction of injection of the nozzle 25. [ The control plate 35 has a rotation groove 35a at the center thereof for receiving the rotation shaft 21a of the injection tube 21 so as to protrude outwardly. A crank wheel 36 which rotates in engagement with the protruding rotary shaft 21a, a yoke 37 which moves left and right by engaging with the crank wheel 36, and a yoke 37 which hits the engaging plate 32, A push rod 38 is mounted. Here, the control panel 35 is mounted with a guide block 35b for guiding the linear movement of the pushrod 38. [

A crankshaft 36a is formed at a position spaced apart from the center by a predetermined distance from the center of the crank wheel 36. The yoke 37 has a rectangular working groove 36a which receives the crankshaft 36a vertically The control rod 35 is connected to the control rod 35 by a control bolt 38a for limiting the flow distance of the yoke 37. [ That is, when the plunger 38 and the yoke 37 move to the right, the crank wheel 36 also makes a right turn. On the other hand, when the plunger 38 and the yoke 37 move to the left, they turn to the left by the crank wheel 36. [ However, when the crankshaft 36a is positioned downward from the concentricity of the crank wheel 36, the rotation is reversed in the direction of movement of the plunger 38 and the yoke 37. [

When the crank wheel 36 rotates by this operation, the injection angle of the nozzle 25 is changed while the injection tube 21 rotates in the same direction. Here, the rotation range of the crank wheel 36 (the injection angle of the nozzle 25) is proportional to the movement amount of the plunger 38. That is, the adjustment bolt 38a fastened to the push rod 38 is blocked by the guide block 35b to prevent movement. Accordingly, the spray angle of the nozzle 25 can be adjusted according to the position of the adjustment bolt 38a fastened to the push rod 38.

Meanwhile, the control plate 35 may further include a leaf spring 39 that engages with the yoke 37 to propel the flow. The plate spring 39 induces propulsion in the direction in which the yoke 37 is moved by the plunger 38 with its own tension. Then, the moved yoke 37 holds the position against the small external force due to gravity or vibration.

Hereinafter, a process of washing the solar panel SP by the operation of the washing unit 20 and the operating unit 30 according to the present invention will be described. First, the support portion 10 is installed on the ground in consideration of geographical characteristics and azimuth angle. The supporting portion 10 is installed at an angle that is optimized to the incidence angle of sunlight as shown in FIG. Therefore, the cleaning part 20 and the operation part 30 are held downward by gravity by the inclined supporting part 10. [

In other words, normally, the plunger 38 is blocked by the retaining plate 32 located on the left side as shown in FIG. 5 and moved to the right along with the yoke 37. The movement of the yoke 37 causes the crank wheel 36 and the spray tube 21 to turn to the right and the nozzle 25 is switched to an angle opposite to the rotation of the spray tube 21. [ If the solar panel SP is to be cleaned in this state, it is connected to a hose which pressurizes the washing water to the connection port provided in the spray tube 21. [ Where the wash water can be pumped from the pump or pumped by the drop of the tank installed at a relatively high position.

When the preparation for cleaning is completed, the valve provided in the hose is opened to pressurize the washing water to the spray tube (21). The pressurized washing water is sprayed at a high pressure through the nozzle 25 to remove foreign substances from the solar panel SP. Here, the driving force for moving to the right side is generated at the same time by the washing water sprayed from the nozzle 25 which is turned to the left. That is, the cleaning unit 20 and the operation unit 30 are moved to the right side by the driving force, and the entire solar panel SP is cleaned.

6, the plunger 38 is blocked by the fastening plate 32 located on the right side and is instantaneously moved to the left side together with the yoke 37 so that the injection tube 21 is switched to the right side. That is, as the propulsion direction of the injection tube 21 is reversed, the washing unit 20 and the operation unit 30 are returned to their original positions. The foreign matter of the solar panel SP is removed by the washing water sprayed even in the returning process. The returned washing unit 20 and the operating unit 30 continuously repeat the process of returning to the right while the angle of the spray tube 21 is originally changed and returning when the movement is completed.

When it is determined that the cleaning of the solar panel SP is completed, the valve provided in the hose is closed. The washing unit 20 and the operation unit 30, which have lost the propulsive force, are gradually lowered down by the gravity and held in a fixed state. Since the propulsive force varies depending on the injection angle of the nozzle 25, the propulsive force can be adjusted by the adjustment bolt 38a in consideration of the installation angle of the support portion 10. [

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as defined by the appended claims. It is therefore intended that such variations and modifications fall within the scope of the appended claims.
