A floating solar light power generator with protective support

The present invention relates to a water-based photovoltaic device system having a protection support, and more particularly, to a water-based photovoltaic device system having a protection support for supporting and protecting the water-based photovoltaic device on the mooring floor. It is about.

In general, a photovoltaic device refers to a power generation system that produces electricity on a large scale by using solar energy by unfolding a panel on which solar cells are attached.

Photovoltaic devices are semi-permanent, easy to maintain, and use of pollution-free solar energy sources, which can be regarded as devices with renewable energy production and eco-friendly features.

Since photovoltaic power generation has a limited amount of solar energy per unit area, installation in the form of a condensing panel is required, while a considerable area of installation space is required.

Such photovoltaic devices are generally installed on land. However, in the case of photovoltaic devices installed on land, there are many difficulties in constraining the installation space. It is a state.

Of course, it is possible to prepare a space to install the photovoltaic device by clearing the mountain, but this requires a lot of land purchase costs and civil engineering costs, there is a problem that does not meet environmentally friendly development in terms of damaging the forest.

In addition, when the photovoltaic device is installed on land, the solar cell module may be overheated by geothermal heat in summer, and thus the photovoltaic power generation efficiency may decrease.

As an alternative to the constraints of the installation space as described above, a photovoltaic device installed in the water is considered.

The water photovoltaic device is installed in such a way as to float the light collecting panel through floating bodies in the water environment such as rivers, lakes, rivers, ponds, dams and reservoirs, thereby overcoming installation space restrictions on land.

In particular, since the water-based photovoltaic device can utilize the shared water owned by the state or local government, the cost of securing land on land can be greatly reduced, which leads to the cost of generating power compared to other renewable energy sources. It can be reduced to a competitive level.

On the other hand, the water photovoltaic device should be fixed so as not to move out of the set range at the installation place by the external force such as the flow of water or wind in the state floating on the water surface.

If the floating structure of the water-based photovoltaic system floats, the alignment between the sun and the solar cell module is misaligned and the amount of power generated is reduced, and the water-based photovoltaic device may be damaged by hitting other objects.

In order to prevent such a problem, the conventional water-based photovoltaic device as shown in Figure 1, the floating body 10 is formed to be floating on the water surface having a predetermined size area, and the floating body 10 The light collecting panel 20 and the floating body 10 provided on the upper portion

It is composed of a support rope 30 for fixing and a fixed block 40 of the weight installed on the bottom surface of the water to fix one end of the support rope (30).

As a result, the floating photovoltaic device can be stably floated on the water surface at all times due to the support rope 30 fixedly supporting the floating body 10. Can be produced by

However, the conventional water-based photovoltaic device described above has the following problems.

During a drought or the like, when the water level of the mooring is excessively low or the bottom of the mooring is exposed to the moor, the float 10 may damage the power generator structure while touching the underwater floor.

That is, not only the bottom of the reservoir, rivers, lakes, etc., but also because a variety of foreign matter, such as stones can sink, causing the floating body 10 is damaged by the deviation of the support load while contacting the foreign matter. It can be.

In addition, there is a problem that the loss of components for photovoltaic power generation by the impact generated when the floating body 10 is in contact with the foreign matter of the mooring bottom.

In addition, when the water photovoltaic device touches the bottom of the mooring base, the bottom of the mooring base may be uneven so that the direction of the light collecting panel 20 may be displaced from the sun.

Accordingly, there is a problem that requires additional work to vary the position of the water photovoltaic device.

Republic of Korea Registration No. 10-1162473

The present invention has been made to solve the above problems, an object of the present invention is to provide a support means on the bottom of the mooring pond mooring the water photovoltaic device even if the water level of the mooring site is reduced or the bottom of the mooring is revealed Water photovoltaic power generation with protective support installed at the water photovoltaic mooring station by means of preventing the floats of the water photovoltaic device from touching the water floor, thereby preventing damage to the water photovoltaic device and damage to components. It is to provide a device system.

In order to achieve the above object, the present invention provides a water-based photovoltaic device comprising a floating body floating on the water of the mooring place, and a light collecting panel installed on the floating body, the bottom of the mooring projecting upward from the bottom The plurality of support posts are installed, the water level of the mooring site is reduced, even if the floating body is lowered, the support post is provided with a water support system having a protective support, characterized in that the floating body is installed so that it can be horizontally seated do.

At this time, the support post, it is preferably composed of a fixed base fixed to the bottom of the mooring base, the mounting portion is installed on the upper end of the fixing base and having a larger diameter than the diameter of the fixing base, and a buffer pad provided on the mounting portion.

In this case, it is preferable that the fixing base includes a hollow fixing part fixed to the bottom of the mooring base and a lifting part elastically supported in the fixing part and provided with a seating part.

In addition, it is preferable that a net is further installed between the support post and the float.

The water photovoltaic device system provided with the protection support according to the present invention has the following effects.

First, since the support posts protrude upwards and are installed at the same height on the bottom of the floating mooring pond, the aquatic solar power generating apparatus does not reach the bottom of the mooring base even if the water level of the mooring site decreases. It is stable in a horizontal state.

Accordingly, even if the water level of the mooring site is reduced, the water-based photovoltaic device does not cause damage due to contact with the mooring floor.

Second, the net is installed between the water photovoltaic device and the support post, there is an effect that can prevent parts loss caused by the impact on the water photovoltaic device.

In other words, the net's elastic force acts as a buffer, so that the offshore photovoltaic device can be lowered gradually, and even if the parts of the offshore photovoltaic device are separated, the net can accommodate it, thus preventing secondary damage and loss of parts. It is.

Third, by forming an elastic body on the support post to elastically support the aquatic photovoltaic device, there is an effect of stably supporting the aquatic photovoltaic device regardless of the bottom shape of the aquatic photovoltaic device.

For example, even if the structure is installed on the bottom of the water photovoltaic device so that the bottom of the water photovoltaic device does not provide a flat surface, the support post is supported while supporting the bottom of the water photovoltaic device. Regardless of the shape of the bottom of the photovoltaic device, it can be stably supported.

Fourth, even if the water in the mooring place decreases, the water-based photovoltaic device is mounted on the support post while maintaining the floating state, so that the angle change with the sun does not occur significantly, so that the power generation efficiency can be maintained without deterioration. have.

The terms or words used in this specification and claims are not to be construed as limiting in their usual or dictionary meanings, and the inventors may properly define the concept of terms in order to best explain their invention in the best way possible. It should be interpreted as meaning and concept corresponding to the technical idea of the present invention.

Hereinafter, with reference to the accompanying Figures 2 to 4 will be described with respect to the water-based photovoltaic device system having a protective support according to a preferred embodiment of the present invention.

The water-based photovoltaic system with protection support is designed to prevent the water-based photovoltaic device floating on the mooring floor from touching the mooring floor even if the water in the mooring evaporates or runs out due to various factors such as dry season. Prevented.

Accordingly, it is possible to prevent damage that may occur due to the water-based photovoltaic device is in contact with the mooring bottom.

At this time, the mooring refers to a reservoir, a lake, a river, or the like, in which floating bodies of the water photovoltaic device are floating.

The water-based photovoltaic system having a protective support includes a support post 100, which is installed at the mooring bottom as shown in FIG. 2.

The support post 100 is installed to protrude upward from the mooring bottom and is provided in plurality.

The height of the support post 100 may be a height such that the floating body 10 does not reach the bottom of the mooring base, and the plurality of support posts 100 peaks should be installed in the same manner.

This is to allow the floating body 10 to be seated while maintaining the horizontal state that was floating in the mooring place when it is seated on the support post 100.

The support post 100 is preferably composed of a fixing table 110, a seating portion 120, and a buffer pad 130.

Fixing unit 110 is a portion that is fixed to the mooring base, and may be configured to be easily embedded in the mooring bottom.

At this time, although not shown, the fixture 110 may be composed of a screw.

When the fixing stand 110 is composed of a screw, not only the support post 100 can be easily installed on the bottom of the mooring base, there is an advantage that the support post 100 can be easily dismantled.

The seating part 120 is a portion in which the floating body 10 is seated and is in contact with the bottom surface of the floating body 10.

The seating portion 120 is formed flat, it is preferable that the floating body is formed to have a large diameter compared to the diameter of the fixing base 110 to be seated in a stable sense.

The buffer pad 130 serves to mitigate the impact in the process of the floating body 10 is seated on the seating portion (120).

The buffer pad 130 is installed on the seating unit 120, and preferably made of the same shape as the top surface of the seating unit 120.

The material of the buffer pad 130 is not particularly limited and may be any material that can alleviate the impact.

In addition, the configuration in which the shock absorbing pad 130 is installed in the seating part 120 is also not particularly limited.

As such, the support post 100 is installed on the bottom of the mooring base as shown in FIG. 2.

When the water in the moor is drained or evaporated, the water level decreases, and the floating body 10 descends in conjunction with the water level.

Then, when the water level decreases more and lower than the highest point of the support post 100, the floating body 10 is naturally seated on the buffer pad 130 of the seating portion 120 as shown in FIG.

Even when the floating body 10 is seated on the support post 100, only the height of the floating body 10 is variable, and since the angle with the sun is not largely changed, even if there is no water in the mooring place, Production can continue to be effective.

Meanwhile, the net 200 may be further installed between the support post 100 and the water photovoltaic device.

The net 200 is to make the floating body 10 fall more stably.

In addition, the net 200 plays a role of minimizing component loss that may occur in the process of the floating body 10 is seated on the support post (100).

That is, even if a part is separated from the aquatic photovoltaic device, since the part can be accommodated in the net 200, it is possible to prevent the parts loss of the aquatic photovoltaic device.

The tension of the net 200 is preferably such that the floating body 10 can be lowered slowly compared to the speed at which the water level is lowered.

Accordingly, the floating body 10 may be slowly seated on the support post 100 as compared with the speed at which the water level decreases.

If the tension of the net 200 is excessively tensioned, since the float 10 is not lowered and is seated only on the net 200, the load of the float 10 continuously acts only on the net 200, so that time passes. Broken nets can cause water-based photovoltaic devices to fall to mooring floors.

In addition, when the tension of the net 200 is excessively loose, the floating body 10 is interlocked with the water level together with the net 200 and is immediately seated on the support post 100 so that the configuration of the net 200 may be meaningless. .

Accordingly, the tension of the net 200 will be preferable if the floating body can be lowered more slowly than the rate of water level decrease.

The net 200 may be fixed to the structure surrounding the mooring place, as shown in Figure 4b, or may be fixed by driving a pile or the like.

On the other hand, the floating photovoltaic device floating body 10, as described so far, although the floating body 10 itself may be a floating material, it may be configured by installing a buoyancy body (11) separately in the structure.

In this case, the bottom of the floating body 10 is not formed evenly due to the buoyancy body 11, the floating body 10 may be damaged by losing balance in the process of being seated on the support post (100).

Accordingly, an offshore photovoltaic device system having a protective support for horizontally supporting the offshore photovoltaic device regardless of the bottom shape of the float 10 is provided.

This is presented as another embodiment of the present invention, and will be described with reference to the accompanying FIGS. 5 and 6.

Prior to the description, the same components as in the preferred embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted.

The support post 100 is composed of a fixing table 140, a seating portion 120, and a buffer pad 130.

At this time, the fixing stand 140 is composed of a fixing part 141 and the lifting unit 142, as shown in FIG.

The fixing portion 141 is a portion fixed to the bottom of the mooring base, and has a hollow interior.

Sliding grooves 141a are formed in both upside and downsides of the fixing part 141 as shown in FIG. 6.

Sliding groove 141a is for guiding the lifting of the lifting unit 142, a detailed description will be described later.

The lifting unit 142 is configured to support the floating body 10 and is installed to be elevated in the inside of the fixing unit 141.

At this time, the lifting unit 142 is elastically supported inside the fixing unit 141.

Accordingly, the spring 150 that can elastically support the lifting unit 142 is installed in the fixing unit 141 as shown in FIG.

A seating part 120 is installed at an upper end of the elevating part 142, and a close contact piece 142a in close contact with the spring 150 is installed at a lower end of the elevating part 142.

The close contact piece 142a corresponds to the width of the spring 150 and corresponds to the gap between the sliding grooves 141a.

At this time, guide protrusions 142b positioned in the sliding grooves 141a are formed at both sides of the close contact piece 142a.

When the lifting unit 142 is lifted by the above configuration, the guide protrusion 142b is lifted along the sliding groove 141a to smoothly lift the lifting unit 142.

As such, the fixing stand 140 of the support post 10 includes the fixing part 141 and the elevating part 142, so that the water-based photovoltaic device is stable even when the bottom shape of the floating body 10 is uneven. Can be supported horizontally.

That is, as shown in Figure 5, the lifting portion 142 of the support post 100 corresponds to the outer line of the structure of the floating body 10, the height is freely variable as the water photovoltaic device balances It can be seated on the support post 100 in a maintained state.

At this time, in consideration of the weight of the water photovoltaic device, it is understood that the elastic force of the spring 150 can be adjusted.

As described so far, in the water-based photovoltaic device system provided with the protection support according to the present invention, even if the water of the mooring place is drained by various factors such as water harvesting and discharge, the floating body of the water-based photovoltaic device is placed on the bottom of the mooring place. Stable to the support post without touching.

Accordingly, it is possible to prevent damage to the water photovoltaic device and to continuously generate electricity regardless of the water level.

Although the present invention has been described in detail with respect to the described embodiments, it will be apparent to those skilled in the art that various modifications and variations are possible within the technical scope of the present invention, and such modifications and modifications are within the scope of the appended claims.
