Description

In the present invention, a solar cell module is arranged on the surface of a floating cover that also serves as an anti-algae measure laid in a water treatment facility such as a water purification plant or a sewage treatment plant, thereby effectively utilizing clean energy.

The cover laid in the water treatment facility is made of FRP, synthetic wood, sandwich panel, aluminum, concrete cast board, tent material, etc. for the purpose of deodorization, algae prevention, fall prevention, and prevention of dangerous materials. In recent years, solar power generation has become widespread for reducing carbon dioxide, and in addition to the conventional purpose, a solar power generation system combined with a solar cell module has begun to be used as a cover. A solar cell module mounting method was devised to provide a design that organically combines the cover function and power generation. In water treatment facilities, due to installation restrictions, provide a panel structure that floats on the surface of treated water that can not be fixed to the housing and can be designed to avoid the use of girders that account for a large specific gravity in the material cost. It is.

Japanese Patent Application Laid-Open No. 2004-228262 or Japanese Patent Application Laid-Open No. 2004-228263 proposes a float type cover panel device. The float according to the present invention has a frame structure, and the solar cell module requires a self-supporting strength and a light shielding function in addition to the original power generation function, and a separate water shielding function film is also required. In addition, since the adjacent floats are fastened by connecting flanges, they have some flexibility in the arrangement direction but do not have a sliding function, and the degree of freedom in the arrangement direction is greatly restricted. Furthermore, since the solar cell module is tilted in one direction, it may be difficult to obtain an appropriate sunlight incident angle depending on the construction direction of the water treatment facility.

The solar power generation device according to the present invention solves the above-mentioned problems and includes the following components.
The FRP levitation body is required to ensure buoyancy, to fix the solar cell module and to the load, to have a light shielding function, and to be easily installed in a water treatment facility.
In view of the above, the floating body of FIG. 1 is provided.
The buoyancy and strength can be designed with the minimum weight because the hat-type rib structure installed at the bottom of the panel can be designed according to the specifications and conditions of each water treatment facility.
The panel body is provided with a stepped flange on the adjacent side, the upper section has a stepped cross-sectional shape when placed on the upper side, and the upper panel and the lower panel are alternated when placed side by side by removing the stepped portion of the lower panel. Installed. This wrapping part realizes perfect light shielding and secures the degree of freedom of panel arrangement.
Since this collar is also provided at the end of the water treatment facility that contacts the chassis, an elastic sheet is fixed to this part with a bolt or the like to ensure an interference function with the chassis and a light shielding function. Dimensional constraints can be relaxed.
Furthermore, although the orientation and angle of incidence with the sun are important factors for securing the power generation function, it is possible to set the optimum positional relationship by using a sheet-like amorphous silicon type for the solar power generation module. .

With the panel device according to the present invention, the FRP floating body does not require reinforcement for imparting high rigidity, and the minimum shape can be designed, so that further weight reduction is possible.
Moreover, further weight reduction can be realized by employing a sheet-like amorphous silicon solar cell.
If a sheet-like solar cell is used, restrictions on the positional relationship with the sun can be greatly relaxed, leading to an increase in power generation.
Structurally, panel devices that are in parallel can be installed freely without sacrificing the light shielding effect in the floating state, and interference with the housing of the water treatment facility can be suppressed.
By disposing the solar cell modules in an uneven manner, the degree of inferiority due to the orientation of the water treatment facility can be alleviated and the degree of freedom can be secured even with respect to the incident angle of the sun.

As a necessary element of the panel device, there is a concavo-convex structure that forms a curved surface on which a solar cell module is mounted at the center portion using an outer peripheral portion constituted by a flat surface and a buoyancy generating hollow body positioned below the base member as a base member.
In addition, a vertical arrangement structure cross section for the arrangement of the floating bodies is taken at the outer peripheral portion. With this structure, the upper panel and the lower panel can be arranged alternately.
The other end of the peripheral member is secured with a ridge that can fix the elastic sheet.
In addition, a gap for the junction box and a handle for removal are required.

One panel has a molding width of 1000 mm and a length of 3500 mm, and a flat portion having a width of 100 mm is set on the outer peripheral surface thereof. The central part has an arch structure with a curvature radius of 15000 mm, and a step of 25 mm is provided to accommodate the solar cell module.
On both sides of the arch, a space for the junction box was secured and a handle was attached. A step was provided in the width direction of the outer peripheral surface, and the upper and lower panels were separated according to the cutting position.
(2) A space having a hat structure was set at the lower part of the outer peripheral plane portion to which buoyancy was applied. The size of the cross section was balanced with its own weight, and a 50 × 100 mm foam was overlaid and integrated with the main body panel.
The buoyancy is 38 kg with respect to 35 kg of own weight, and the hat structure sinks about 90 mm.
3 Solar cell module A flexible solar cell module with a mounting width of 700 mm and a length of 3000 mm was fixed with rivets and wired in series with a waterproof connector.
