Abstract

The present invention relates to the construction of a solar power plant using a phenomenon of a light condensing effect in which the illuminance of a light source is 25-30% higher and brighter than the illuminance of direct sunlight in front of the sun when direct sunlight and reflected light incident from all directions are concentrated and combined within a given appropriate interval space. According to the present invention, provided are a space part, a reflector structure, and a transparent screen window. In the space part, double-sided solar cell plates or transparent double-sided solar cell plates are stacked in layers or zigzags at appropriate intervals to be stacked vertically, and a space between reflected light and direct light becomes a space of light collection point so that the solar cell generates power. The reflector structure converts direct sunlight into orthogonal reflected light. The transparent screen windows are installed on the entire front of a structure to prevent contamination of the double-sided solar cell plates and reflectors located in an internal space of the solar power plant and to control the temperature of the internal space. In order to secure the direct sunlight light source despite the movement of the solar light source, an automatic tracking movement function for moving horizontally and vertically is included to allow the front surface of the power plant structure to face the light source head-on. In addition, a system has a function to reduce and restore an external size of the structure to supplement the safety of the power plant structure in response to change in external weather conditions, that is, a function which enables folding and unfolding of structure plates composed of the screen window and the reflector. Among power sources required for the power plant structure to automatically track the solar light source and required for folding and unfolding operation functions to secure the safety of the structures, natural power sources can be applied as a main power source. Accordingly, solar power generation is possible even in narrow places or spaces in which solar light sources are captured.

Description

{Moving solar generating plant system with vertical multi-layer solar cell array using reflective sun-light collection effect.}

The present invention relates to a photovoltaic power plant construction type and method, and the current construction form and method is a built-in method by laying the solar cell panels, which are key components, on a flat surface with a certain slope at an appropriate place to receive sunlight from a solar light source. It is installed and fixed, or it is attached to a given wall or roof surface in a flat plane. Therefore, in order to achieve proper capacity generation, it is necessary to occupy the required amount of floor area for flat installation in proportion to the size of the target capacity. Depending on the location of the installation site, the power generation capacity is inevitably limited due to the limitation of the flat floor area. Therefore, in the present invention, while evaluating the current solar power plant construction type as a passive power generation type according to the location of the place, it is intended to present a solar power plant construction format that can actively generate power regardless of the limitations of the place and the limitation of the location. will be. I think the key to solving this problem lies in using the unlimited vertical space area. To this end, the present invention relates to a solar power plant construction form and method in the form of a rectangular parallelepiped structure of a multi-layered dense form or a zigzag multi-layered compact form of the above solar cell plates in the vertical direction.

For example, in the case of constructing a flat solar power plant with 20 solar panels (3m ² ) measuring 1m x 3m in size, the required site area is at least 70 ^~ 80m2. In the case of a construction method by design, only about 15 to 16 m ² is required.

If the number of solar cells is additionally increased to 40 or 60, the current method requires at least a flat area of 140 to 160 m ² or 210 to 240 m ² , but in this design, only the height of the power plant structure is increased in the vertical direction. However, the required area does not increase.

In this case, the solar cell board of the present invention is based on a double-sided solar cell board capable of photovoltaic power generation on both upper and lower surfaces.

Existing photovoltaic power generation method should be direct sunlight, which is the light source of the sun, but in the present invention, in the shape of a rectangular parallelepiped structure, a reflector that spreads out at an angle of 45 degrees from the edge of the rear is attached to all four sides except the front side. Installed, and as the direct sunlight incident on these reflectors is bent and reflected by 90 degrees, the reflected light reflected from the left and right upper and lower reflectors passes between the solar cells placed in a horizontal layer or zigzag form at appropriate intervals, and also It is a photoelectric effect generated by a light-collecting effect light source that is secured by concentrating solar light along with direct sunlight incident between the front gaps.

In order to confirm the intensity of the brightness of the solar light concentration effect among the five (5) above, the present inventor first performed the triple (3) type concentration effect twice in a simple experiment. That is, open the left and right sides (40x11cm) and front (20x11cm) of a rectangular box measuring 20cm x 40cm x 11cm in height, attach the above-mentioned reflectors to the left and right sides, and face the open front in a straight line with the light source Therefore, as shown in the photo below, left and right reflected light shining into the inner space of the experiment box and direct sunlight entering the front are concentrated in three (3) layers, and the intensity of the light that becomes brighter was measured and confirmed with an illuminometer. As a result, it showed a brightness state with a concentration effect intensity that far exceeded the measured illuminance of direct sunlight measured with a straight front focus with the sun, the light source, at almost the same location.

The experimental result data shows that the illuminance of direct sunlight at 14:40 on December 14, 2020 (Monday) was 920Fc, and the illuminance of three (3) triples was 1200Fc, showing about 23.4% of the condensing effect. (Friday) The illuminance of direct sunlight around 14:30 was 870Fc, whereas the illuminance of three (3) layers was 1050Fc, showing about 20.7% of the condensing effect.

Accordingly, the present invention is based thereon. If the test box is more precise and the reflector is replaced with a high reflector, it is judged that the condensing effect can be expected to be at least 25~30%.

In addition to this, the reflector structures attached to the upper and lower surfaces of the rectangular parallelepiped power generation structure seem to be only a single-sided light source reflector limited to the upper and lower surfaces of the solar panel placed on the top and bottom, but now it is a transparent double-sided solar panel. In the situation where the manufacturing technology is complete, even the reflected light of the upper and lower reflectors can be transmitted and illuminated to the inner space of the transparent solar cell panels. The intensity of the brightness and the condensing effect will increase more and more. The present invention is also based on reflection of such situation development.

As described above, the photovoltaic power plant structure construction method made in the present invention concentrates as much sunlight as possible between the solar cell plates placed in layers or in a zigzag form. It is limited to the front of the structure body and the reflector spread out at an angle of 45 degrees to the left and right. In addition, the light source moves from east to west, and the moving light source angle also varies by season. In order to overcome these limitations, movement and angle differences and to secure the maximum and best solar light source, the front of the power plant structure must always face the sun, the light source, in a straight line. In order to do this, the front of the power plant structure according to the present invention, which is a unit structure shape, must be capable of automatic tracking movement along the trajectory of the sun, which is the light source.

In addition, in order to prevent and block contamination of the surfaces of the solar cell plates and reflectors located in the inner space of the unit structure of the power plant according to the present invention by snow, rain, fine dust, etc., a blinding window is installed over the entire opening through which light enters the unit structure of the power plant.

In addition, in order to increase the power generation capacity of the solar power plant according to the present invention, it is necessary to increase the vertical height of the unit structure. Accordingly, the size of the reflector and the front window structure positioned on the left and right upper and lower surfaces also increases in proportion to the increase in height. In this case, such a structure should be a structure capable of folding/unfolding the outer plate of the shielding window and reflector structure so that it can actively cope with external weather conditions such as snow, rain and wind, and environmental changes after sunset.

In addition, in order to improve the power generation capability of the power plant according to the present invention, the surface of the reflector is made to be a high reflector so that the direct sunlight incident on the front of the power plant is reflected at right angles without loss from the reflector.

In addition, the basic materials of the solar cell plates and reflectors, which are constituent materials of the photovoltaic power plant according to the present invention, are relatively lightweight materials. The unit structure made of these lightweight materials is vulnerable to changes in external weather conditions, especially the wind pressure, so that it can have a skeletal structure that can be prepared for overcoming it and an appearance made of light and strong plates.

The structure shape of the photovoltaic power plant according to the present invention is a unit structure as described above, so it is placed on one pedestal while maintaining an inclination angle of about 30 degrees, a basic angle of which the front light emitting window can face the solar light source. Inside this pedestal, a cylindrical shaft device that can rotate 180 degrees left and right while sufficiently supporting the entire load of the structure is installed. The device is installed in separate spaces on the left and right sides of the cylindrical shaft and is connected to the lower support surface of the structure. As such, it is characterized in that it enables automatic tracking movement along the trajectory of the sun, a light source, when connected to a detection sensor that enables these devices to operate automatically, and only when power is supplied.

In addition, the material of the window covering the entire front of the power plant structure is a transparent ultra-thin fluororesin film (ETFE) material, which weighs 1/100 of that of glass, has a light transmittance of 20% higher than that of glass, and is said to have superior insulation effect than glass. The standard for attachment is that the entire front of the power plant body, which is a rectangular parallelepiped shape, is fixedly attached to the body structure, and the left and right reflector light intake windows can be folded/unfolded. It is characterized in that it is possible to reinforce the rib in the form of dividing it into an appropriate size.

In addition, the reflective plate structure, which is a right-angled isosceles triangular tetrahedron, consists of plates attached to and connected to the structural skeleton forming the left, right, upper and lower side structures of the power plant body. To make it fold/unfold, the length of the body in the vertical and vertical direction should be about 10~15mm (thickness of the skeleton) longer than the length in the horizontal direction, and a small Kia motor is used to operate the folding/unfolding function. In the order of folding, the first front blinding window is folded 90 degrees to the side of the body based on the vertical vertical frame at the front of the body, and secondly, the main reflector is folded at 45 degrees based on the vertical vertical frame at the rear of the body to the side of the body The third one is to make the lower cover of the upper and lower reflectors of the reflector fold about 90 degrees based on the horizontal lower skeleton on the side of the body so that it is in close contact with the main reflector, and the fourth upper reflector cover overlaps the lower reflector cover. It is characterized in that it is folded into a shape.

In addition, since the constituent materials of the power plant structure are plate-shaped materials, the durability strength that can respond to wind pressure caused by changes in external atmospheric conditions is considered relatively weak. As a countermeasure against this, the structural materials and structural frame of the reflector structure should be strengthened to be able to withstand the wind pressure up to a certain level only with its own durability strength. The entire skeleton of the power plant structure is connected up and down left and right using the rectangular parallelepiped external frame frame, which is the main body of the power plant, as the central base skeleton, and the rear skeleton of the main body is inclined at an angle of about 30 degrees so that the power plant structure faces the solar light source. It is fixed in the form of attaching to the structure of a sturdy support stand so that it can be placed as a pedestal. The solid support structure becomes the foundation for the safety support of the power plant structure that is attached to one side and is fixed, and at the same time has a counterweight function to achieve weight balance based on the central axis of left and right rotation attached to the lower surface. Make sure that all necessary equipment is built-in. The central axis of the left and right rotation is connected to another fixed base base support structure, and the inner space of this base support structure is characterized in that a hand-wound mechanism that can generate natural power and an energy storage system (ESS) are arranged.

Power plant structures also need power to operate actively. This power also requires the power to enable the power plant structure to automatically track the trajectory of the solar light source and move left and right, the hydraulic system for angle adjustment to focus with the solar light source, and the power required to operate the folding/unfolding function of the reflector structure in preparation for wind pressure. do. If this is divided, it is called regular power because continuous power is required for automatic tracking of left and right movement, and the hydraulic system for angle adjustment and folding/unfolding operation of the reflector can satisfy its functions by instantaneous operation when necessary, so it can be called temporary power. , in this case, the regular power is supplied by the physical energy of the large spring spring, which is the power of the large clock, and the temporary power is characterized by using its own stored electrical energy.

Compared to the current solar power plant construction method requiring a flat site as wide as the size and area of the solar panel as the solar panel is installed and fixed in a flat manner, the present invention is vertically layered or zigzag As it is constructed in the form of a multi-layered compact rectangular parallelepiped structure, the required area is dramatically reduced. If the area is 3 to 4 times the size of the selected solar panel, it is possible to construct a power plant with a significant level of power generation capacity, so it can be built on a small space site or on the roof, roof, ceiling space, and balcony of all buildings. In addition, although the current method is exposed to snow and rain or fine dust, the inside of the power plant of the present invention is protected from the above pollutants by blocking the outside space with a blind window, so it is considered to be superior to the present in power plant maintenance and durability.

In addition, transparent thin-film solar cells have been developed and are also called double-sided solar cells.

In this case, in the current power generation method that uses direct sunlight as a power generation energy source, it is considered that only one side of the power generation is possible. Since the present invention is a power generation method using solar reflected light, it is considered that it can be more effective to utilize the above double-sided solar cell plates because it is an invention on the premise of application of double-sided solar cells.
