But sunshade can solar energy power generation's sunshade ball

Technical Field

The invention relates to an evaporation-preventing and water-saving sun-shading ball, in particular to a sun-shading ball which can reduce the water temperature and prevent microorganisms from increasing, can shade sun and can generate power by solar energy.

Background

According to related reports, 9600 million sun-shading balls are thrown into a los angeles reservoir by emergency measures in order to cope with extreme arid weather locally in the city of los angeles in California USA, so that water evaporation of the reservoir is reduced, 3 hundred million gallons of water is saved for agricultural irrigation every year, and simultaneously algae generation and water damage of drinking water under sunlight are avoided. A large number of black spheres are put into water to block sunlight, but the black spheres absorb heat to enable the temperature of the water to rise, so that microorganisms in the water body can increase, and the water quality is poor.

Disclosure of Invention

In order to solve the technical problem, the invention provides a sunshade ball capable of shading sun and generating power by solar energy, which comprises a ball body capable of floating on the water surface, wherein the surface of the upper half part of the ball body is pasted with a solar panel, a circle of strip-shaped parts with suction are arranged around the middle waist part of the ball body, and a counterweight part is arranged inside the lower part of the ball body.

Furthermore, the sphere is hourglass-shaped, the lower part of the sphere is a hemisphere, and the volume of the upper part of the sphere is smaller than that of the lower part of the sphere.

Further, the component forming the sphere is a PVC material.

Further, carbon black is added to the spherical material.

Further, the solar panel is a spherical solar panel.

Further, sand is filled in the counterweight.

Furthermore, the middle of the ball body and the upper part of the weight part are designed to be hollow.

Further, the strip is an annular magnetic tape.

Has the advantages that:

the ball body is sealed by PVC material and sand filled at the bottom to form a balance weight. Most of the hollow state in the sphere. The solar power generation board is attached to the upper half part of the sphere. And placing the container to a place (countless) where water sources need to be protected. Not only protects the water source, but also generates electricity, and is green and environment-friendly.

The spherical solar panel has the advantages that the light receiving surface is always upward under the action of the balance weight in the sphere, namely the solar panel, and the light receiving body (upper hemisphere) is always upward. Secondly, it can be maintained normally in case of fluctuation. The superposition Rohan effect can not be caused by large wind waves.

Detailed Description

The present application is not limited to the following examples, and specific implementations may be determined according to the technical solutions and practical situations of the present application.

Embodiment 1, as shown in fig. 1, but sunshade ball of sunshade solar energy power generation includes can float at the surface of water spheroid 2, spheroid 2 is the ball type, spheroid 2 includes that the upper surface pastes solar panel 4, and middle waist is around being provided with the strip 3 that the round has suction, be provided with counterweight 1 below the spheroid. The component of the sphere is PVC material, and the sphere is a high-density polyethylene sphere, and carbon black is added into the sphere material. As shown in fig. 2, the sphere 2 may be configured as an hourglass shape, the lower part is a hemisphere, and the upper part has a smaller volume than the lower part, so as to form a tumbler. The stability in water is better, and the wind and wave resistance can be better.

In embodiment 2, as shown in fig. 1, the spherical solar panel 4 is attached to the upper half part of the sunshade ball capable of sunshade and solar power generation, and photoelectric conversion is realized through the solar panel 4, so that heat is prevented from being transferred to the water body, and the increase of the growth of microorganisms in the water body is avoided. Meanwhile, the laying area of the solar panel is increased, and the method is an economical and practical laying method for water solar floating solar power generation.

Embodiment 3, the weight member 1 may be provided as sand or other material with suitable density. The baffle is arranged above the counterweight 1, the filler in the counterweight 1 can be fixed in the counterweight cavity, and when the counterweight is used, the PVC ball can be punched, quantitative sand is injected, and then sealing is performed. The middle of the ball body and the upper part of the counterweight part 1 are designed to be hollow. The light receiving surface is under the action of the balance weight in the sphere, and the light receiving body (upper hemisphere) is always upward. Secondly, it can be maintained normally even in case of fluctuation. The Grosham effect cannot be caused by the large wind waves. Set up the counterweight in spheroid inside, and do not select the mode of the external rope system heavy object of spheroid, be favorable to placing and hide the sun ball and twine by aquatic alga or fabric stone etc. lead to the spheroid skew, can not make the solar panel face up all the time. The hollow arrangement of spheroid is favorable to increasing buoyancy, and is favorable to isolated heat.

Embodiment 4, as shown in fig. 2, but the middle waist maximum diameter department of solar energy power generation's sunshade ball is equipped with the circular tape that has suction in the big periphery department, can make the sunshade ball adsorb together, can increase spheroidal stability on one hand, even the strong wind condition, make the photoreceptor have the one side that has solar panel 4 all the time up, on the other hand lay in a large number on the water, can gather together, form a whole, can be more rigorous to carry out the sunshade, improve the sunshade effect, and be favorable to reducing the administrative work in later stage.

The black plastic is irradiated by the sun for a long time and is subjected to mutual friction and collision to cause the aging of the plastic, and a plurality of plastic particles are released into water to cause the standard exceeding of a plasticizer. The strip-shaped parts 3 can reduce mutual collision and friction among the black plastics, and the throwing and the collecting are convenient. The spherical solar panel covers the black plastic balls, so that the black plastic balls are prevented from being irradiated by the sun for a long time, the aging of the black plastic balls is reduced, and the release of plastic particles into water is reduced.

The solar panel 4 is generally formed by a solar panel, and the solar panel 4 faces upwards and does not contact the water surface, so that secondary damage to the water body is avoided. The spheres are adsorbed together by the annular magnetic tape, and a large number of sun-shading spheres are connected in series or in parallel to form a solar cell matrix with larger output power. The sun-shading balls with the solar panels 4 are numerous, and the sun-shading balls are thrown in water areas such as reservoirs and the like, which have wide areas, stable runoff, low wind speed, good illumination conditions, small water level change, good development conditions, no large-scale shipping, ecological non-sensitive areas and the like. A storage battery pack, a controller and an inverter are arranged on the shore of a water area or in a manner of bearing by a PVC floating body. The solar cell module is used for converting solar energy into electric energy to supply to a load to work or charge the storage battery pack, the controller is used for protecting the charging and discharging of the storage battery pack, the storage battery pack is used for storing the electric energy, and the inverter is used for converting direct current into alternating current.

The above description is intended to be illustrative of the preferred embodiment of the present invention and should not be taken as limiting the scope of the invention, which is defined by the appended claims.
