Description

  The present invention relates to a floating water solar power generation apparatus suitable for installation on the surface of lakes, dam lakes, pools, rivers, seas, and the like, particularly in park ponds.

  A solar power generation device not only requires a large area for expanding a solar cell panel (solar cell module), but also requires a large amount of cost for installation, so a solar cell on a float that floats on the water due to problems such as installation location. A type of power generation device with a panel has been developed.

  Conventional water float solar power generators consist of a water float made by connecting a plurality of resin foams wrapped in a vinyl chloride skin sheet, and a large solar cell panel mounted on each resin foam unit. An area-capable one (Patent Document 1), and a plate-shaped support base is installed on a plurality of floating bodies, a solar cell panel is installed on the support base, and a weight for stabilization is suspended from the center of the support base. And the like for strong wind resistance (Patent Document 2).

  However, as is generally true for conventional solar power generation devices, dust adheres to the solar cell panel on the top surface, and the power generation efficiency is thereby reduced, so it takes time and effort to clean up the dust. In addition, in the snowy area, there was a disadvantage in that it snowed in the winter and caused a state where power generation was impossible. In addition, although the solar cell panel has a problem that the power generation efficiency is reduced even by heat storage, the above-described conventional floating float type solar power generation device has not solved the problem caused by such a natural environment.

  In view of the above circumstances, this device can rationally remove dirt, heat storage, or snowfall that causes a decrease in power generation efficiency or inability to generate power, and is suitable for beautification of the environment. It was an issue to provide.

  In order to solve the above-described problems, the present invention provides a concave hole that extends below the water surface in the center of the float table floating on the water surface, and a solar cell panel is stretched over the float table in whole or most. It is installed so that the fountain sucks and blows out the water below the surface of the water into the concave hole and flows down on the solar cell panel, and the fountain is always immersed in the water to suck the water below the surface of the water. A horizontal axis that supports the fountain in a recessed hole of the float table so that the fountain can fall over, and the fountain by overturning around the horizontal axis. A floating float type solar power generation device is provided, in which the horizontal axis that pivotally supports the fountain is attached to the upper portion of the recessed hole so that the water is lifted up or in the upper portion of the recessed hole.

  Since the floating float solar power generator is configured as described above, the power generated by the solar panel is used for the power to operate the fountain, and the fountain water is used by the water below the surface where the float table floats. And it falls on the solar panel. Also, when the water level becomes low, the fountain rolls around the high horizontal axis located at the top of the concave hole and retreats from the pond bottom.

  As described above, according to this device, not only dirt on the fountain dropped on the solar cell panel is removed, but also overheating due to solar heat storage is prevented in the summer, and snow is accumulated in the winter. Therefore, it is possible to rationally remove the situation where power generation efficiency is reduced or power generation is not possible using the energy of the water below the surface of the water and solar energy, and the monument function that the fountain rises in the center makes it possible to It has the excellent effect of being suitable for beautifying the environment. The “recovery of the power generation capacity of the solar battery panel 3 by watering” is as shown in the graph (FIG. 7) and Table 1 in Example 1 described later, and the effect by this is remarkable. In addition, there is an excellent effect that the fountain can be evacuated from the bottom of the pond when the pond is dried up.

It is a perspective view which shows the use condition of the water float type solar power generation device of this invention. It is a top view which shows the attachment state of the fountain in the center part of the same float type solar power generation device. It is a longitudinal cross-sectional view of the same part. It is a top view which shows the arrangement | sequence of the installation member which receives a float table and a solar cell panel on it. It is a longitudinal cross-sectional view which shows the structure which supports a solar cell panel on a float table. It is explanatory drawing which shows a water float type solar power generation device systematically. It is a graph which shows about "recovery of the power generation capability of the solar cell panel 3 by watering" in use of the same floating type solar power generation device. It is a top view which shows an example of the arrangement | sequence of a solar cell panel.

  In this device, the floating float type solar power generation device P has a solar cell panel 3 disposed on the float table 1 and is equipped with a fountain 5 or the like. However, as shown in FIG. , A connection box 30, a power conditioner 32, a power receiving / transforming facility 34, a pump power control panel 36, a data collecting device 40, a liquid crystal display device 41, etc., of which at least the power receiving / transforming facility 34 or after the broken line in FIG. Equipped on the onshore management tower.

  The fountain 5 is provided for the purpose of melting snow, etc. in addition to cleaning to remove dirt on the solar cell panel 3 and cooling of solar heat. In order to secure these effects and increase the efficiency, the upper surface of the solar cell panel 3 is configured so that the water of the fountain easily flows and is inclined from the central part to the periphery so as to prevent the water from staying. It is desirable.

  The shape and structure of the float table 1 and the arrangement of the solar cell panels 3 constituting the knitted group 3a (array) vary. FIG. 1 and FIG. 7 show different cell arrangement examples. In addition, although not shown, an anchor is attached to the float table 1 so as not to be washed away by a strong wind or the like.

  The power generation by the solar panel 3 is used for the power of the fountain 5 and the surrounding lighting, but once it is collected in the management tower, surplus power is sold to an electric power company or stored.

  FIG. 1 to FIG. 6 show an example of a floating float type solar power generation device P installed on the surface of water W of a park pond, which is diagonally placed on a square plate-like float table 1. Solar cell panels 3 are arranged for each of the four sections that are roughly divided, and a fountain 5 that uses the water W of the pond is provided at the center.

  The float table 1 is formed by connecting a large number of blocks 2, 2,... Made of foamed resin vertically and horizontally (see FIG. 4), and has a rectangular concave hole 7 at the center. For the mutual connection, a large number of connecting pieces formed in a dovetail shape at both ends are used, dovetail grooves are provided on the side surfaces of the blocks 2 and 2, and the side surfaces are joined to each other via the connecting pieces.

  The installation structure for supporting the solar cell panel 3 is formed by arranging channel-shaped lower connecting members 9 a, 9 a, and upper connecting members 9 b, 9 b,... In parallel along the diagonal lines of the float table 1. The lower connecting member 9a is connected to the block 2 with the stud 11 and the upper connecting member 9b is connected to the lower connecting member 9a with the screw 13. As a result, the float table 1 is in a stable assembled state, so that the solar cell panel 3 is stably supported on the upper connecting member 9b.

  The solar cell panel 3 is composed of knitted groups 3a, 3a, 3a, 3a as four solar cell arrays arranged like a lotus leaf around the concave hole 7, that is, with the fountain 5 at the center. The mounting members 17, 17,... Are arranged vertically and horizontally on the upper connecting member 9b, and the adjacent solar cell panels 3 and 3 are connected to each other with the mounting members 17, 17. The attachment member 17 is formed with receiving portions 19 and 20 of the solar cell panels 3 and 3 at the lower portion, and one of the receiving portions 19 is fixed to the upper connecting member 9b with a screw 21.

  The fountain 5 is constructed by installing a water guide pipe 25 on a water absorption pump 23 (with a built-in motor) immersed in the water W of a pond and attaching a nozzle 27 to the upper end thereof. (Refer to the one-dot and two-dot chain lines.) When the water level becomes low, it rolls over from the bottom of the pond by rollover. For attachment of the fountain 5, the support device is configured in the recessed hole 7 by a stainless steel channel member. A stainless steel member is used for each of the above channel members.

  2 and 3 show how the fountain 5 is attached. The pair of front and rear longitudinal members 31 and 31 are screwed to the left and right side surfaces of the concave hole 7, and the pair of front and rear support members 33 and 33 are secured to the left and right longitudinal members. The square mounting frame 35 is screwed onto the support members 33, 33, and the horizontal shaft 29 described above is installed on the mounting frame 35. A chain 37 is attached between the water absorption pump 23 and the support member 33 to hold the water absorption pump 23 in a continuous manner.

  FIG. 6 shows an overall system configuration of the floating float type solar power generation device P. The direct current from the solar cell panel 3 is collected in one circuit by the junction box 30 and then sent to the power conditioner 32. Then, the alternating current is divided into the pump power control panel 36 and the power company side 38 in the power receiving / transforming equipment 34. Further, the pump power control panel 36 is divided into an ordinary fountain form and a snowmelt fountain form, and the fountain 5 operates effectively in response to environmental changes.

As described above, the floating float solar power generation device P of the present invention is not only a monument, but can maintain its power generation capability by cooling the solar panel 3 using the water of the lake water that floats it. It has the ability. The results of demonstrating the effectiveness of this watering by looking at the power generation process for one day for the above-mentioned floating float solar power generation device P are presented as a graph (FIG. 7) and a table (Table 1). Both are measured by installing them in a pond in a prefectural park in Imizu City, Toyama Prefecture.

(About graph)
FIG. 7 shows the intensity of sunlight (kw / sq.m.) And the amount of power generation (kwh) for each hour of the floating float solar power generator P installed on the pond on April 25, 2010, along with changes in the outside temperature. The fountain 5 was operated intermittently for 5 minutes every 2 hours at 7 o'clock, 9 o'clock, 11 o'clock, 13 o'clock, and 15 o'clock. In addition, a continuous line shows the value of direct current | flow, and a broken line shows the value converted into alternating current, respectively.

  From this, the relationship with the fountain 5 appears remarkably in the time zone around noon when the sunlight is strong. That is, when the fountain 5 is operated at 11:00, the power generation amount suddenly increases in a V shape, and when the fountain 5 is stopped, it gradually decreases from the peak, and at the 13:00 fountain, it reaches the peak again. Since it is in the process of decreasing, the amount of power generation has also dropped rapidly from the peak due to the fountain stop.

  In addition, in the beginning of the morning and the latter half of the afternoon, since there is little heat storage of the solar cell panel 3 due to the small amount of sunlight, the effect of watering is not so much seen.

(About power generation effect table by fountain operation)
Table 1 shows an experiment conducted on the same pond as in the case of the above graph, and measured in the same manner as above from 9:00 to 17:00 on April 28, 2010. That is, the fountain 5 was operated intermittently for 5 minutes every 2 hours at 9:00, 11:00, 13:00, and 15:00. And the amount of power generated every hour is recorded, but when the fountain is operated every hour at 9 o'clock, 10 o'clock, 11 o'clock, 12 o'clock, 13 o'clock, 14 o'clock, 15 o'clock, 16 o'clock The estimated value and the estimated value without fountain operation are shown simultaneously. The reason for the estimated value is that the same floating float solar power generator P cannot be used for simultaneous measurement under different conditions of the fountain time. For this, a value was obtained by calculation of a computer from an actual measurement every two hours.

  If it is every hour as seen from Table 1, the operation frequency of the water absorption pump 23 increases (from 4 times to 7 times) and the power consumption for that increases (from 1.833 kwh to 3.208 kwh), The actual power generation amount after subtracting this from 91.644 kwh to 95.291 kwh is about 15% up to 20% up in comparison with no fountain. I found it good. Therefore, the monument function can be maintained without sacrificing the power generation efficiency. In other words, this table shows that it can contribute to environmental beautification as well as power generation.

  FIG. 8 shows different examples of the arrangement of the blocks 2, 2... Of the float table 1 and the arrangement of the knitted group 3 a of the solar cell panel 3, but the other is as described above.
