Description

Solar power device

The present invention relates to a solar power device, and more particularly, the angle of inclination of the solar panel freely and easily according to the south middle elevation of the sun so that the solar light and the solar panel located at the south middle elevation which changes with the season at right angles. Not only can the angle of inclination of the solar panel be kept constant even under typhoons or strong winds, but it is not damaged, and algae can not discharge the excrement while staying. Even if the installation is easy to adjust the inclination angle of the solar panel, relates to a solar power device.

Modern society can be said to be maintained by electric energy, and electric energy is mainly obtained by hydro, thermal and nuclear power, which has the advantage that there is no emission of pollutants, but since it must be abundant in quantity, it is necessary to build a hydro power plant. While nuclear power is difficult to treat radioactive pollution and waste radioactive materials, nuclear power plants that generate electricity by burning fossil fuels are located in hydroelectric power plants and radioactive pollution such as nuclear power plants. The advantage is that there is no problem.

However, due to industrial development, environmental pollution is getting worse, and in particular, global warming, which is accelerating with air pollution, can cause catastrophe around the world. Therefore, the UNFCCC is trying to regulate the CO2 emissions of each country. It was adopted at the United Nations Conference on Environment and Development (UNCED) in June 1992.

Carbon dioxide, which affects the global warming as described above, is mainly generated during the combustion of fossil fuels. Thus, in order to reduce the consumption of fossil fuels, carbon dioxide has no pollution, such as solar energy, wind power, and tidal power. Much research is being done on technologies that can be converted into electrical energy.

However, there is a positional constraint that the difference between tidal and tidal waves must be large in order to use tidal power, and that strong winds must be continuously blown in order to use wind power. As an ideal energy source, there are few positional restrictions except in the polar regions.

Such solar energy may be used in the form of thermal energy directly obtained from sunlight, electrical energy converted from the thermal energy obtained, or electrical energy generated from solar panels irradiated with sunlight. The solar power generation apparatus using a solar panel that can be used in small electronic products such as a clock and the like is as follows.

A solar power generator is a device that obtains electricity by irradiating solar light to a solar cell. A solar cell is a device in which a p-type semiconductor and an n-type semiconductor are bonded. Photons are absorbed to generate a pair of electrons and holes, and electricity is obtained by moving the electrons and holes to the n-type semiconductor and p-type semiconductor side, respectively.

The solar power generation apparatus using the solar panel combined with a plurality of solar cells as described above, the solar power unit, according to the method of receiving the solar panel, the direct light-type direct irradiation of solar light to the solar panel, reflector or Fresnel lens It can be classified into a condensed light type so that the collected solar light is irradiated to the solar panel using a light, and the like, and there is a fixed type in which the solar panel does not move and a tracking type in which the solar panel moves along the sun.

However, the condensing type and the tracking type are not only complicated in structure but also expensive, but are suitable as a large-scale electric power plant, but direct light-receiving and fixed solar power generators are widely used in small-scale devices including street lamps.

Conventional small-scale solar generators (hereinafter referred to as "solar generators"), which are direct light-receiving and stationary, are fixedly installed so that the light receiving surface of the solar panels faces the south-high elevation of the sun, and the solar panels are fixed. Because of its efficiency is disadvantageous.

That is, the south mid-high elevation of the sun changes with the season, but in the conventional solar power generation system, since the solar panel is fixed at the south mid-high elevation at a specific point in time, when the light receiving surface of the solar panel and the south mid-high elevation do not form a right angle, There is a disadvantage that the efficiency is further reduced.

In order to solve the shortcomings of the fixed solar measuring device as described above, a device for manually adjusting the tilt angle of the solar panel according to the middle and middle angles of the sun has been posted in Korean Patent No. 660043.

The registered patent is such that the horizontal rotating shaft coupled to the solar panel is rotatably supported by a plurality of struts, and combines the first coupling plate through which the fixed coupling hole is formed in the upper surface of the opposite sides of each strut perpendicular to the rotation shaft, A plurality of fan-shaped second coupling plates facing each first coupling plate adjacent to each other and having a plurality of rotational coupling holes therethrough are coupled to the rotating shaft.

The registered patent, by rotating the rotary shaft to match any one of the plurality of rotation coupling holes provided in the fixed coupling hole of the first coupling plate and the second coupling plate, and then bolts / matched fixed coupling hole and the rotary coupling hole By fixing with a coupling member such as a nut, it is possible to adjust the inclination angle of the solar panel up and down.

In other words, by rotating the rotating shaft to change the position of the rotary coupling hole coinciding with the fixed coupling hole is a structure that makes it easier for people to control the solar panel.

However, the registered patent is provided with a pair of first coupling plate in a plurality of struts, the second coupling plate is 1: 1 correspond to each first coupling plate, a plurality of pairs of fixed and rotating coupling holes matched with each other Since one person can not be fixed at the same time as a coupling member, when one person adjusts the inclination angle of the solar panel, there is a disadvantage that a lot of work time by having to be fixed sequentially from one side to the other side.

In addition, when one person dismantles the coupling member for adjusting the angle of the solar panel, one side to the other side must be disassembled one by one in turn. In this case, it takes a lot of time, and the angle of the solar panel in the state where all the coupling members are disassembled. When adjusting the wind is not easy to adjust the angle of the solar panel due to the wind pressure, of course, there is a disadvantage that it is difficult to fix the solar panel using the coupling member after the angle adjustment is completed.

In other words, if the wind pressure acting on the solar panel is large, while the angle is adjusted as well as the angle adjustment, while holding the fixed coupling hole and the rotary coupling hole as the coupling member, while holding the solar panel firmly so as not to rotate by the wind pressure coupling member The fixed coupling hole and the rotary coupling hole must be combined using the bar. In particular, when the wind pressure applied to the solar panel is large, it is not easy for one person to control the inclination angle of the solar panel.

In addition to the above, there are a number of devices for adjusting the inclination angle of the solar panel according to the south middle altitude of the sun, such as the "inclined angle adjustable solar photovoltaic device" of Korean Patent Publication No. 840400, but the conventional devices are solar panels or solar panels As a structure for directly rotating the mounted base (hereinafter referred to as "solar panel"), there are the following problems.

Conventional solar panels are provided with a rotating shaft on the back, and the rotation axis is rotated to adjust the inclination angle of the solar panel, the side of the solar panel in the north-south longitudinal direction of the rear side of the solar panel is coupled in the east-west longitudinal direction, The rotating shaft is rotatably coupled to the support, and both the east and west longitudinal ends of the solar panel are supported by the rotating shaft, but the north and south longitudinal ends are not supported at all.

Therefore, in case of typhoon or strong wind, the inclination angle of the solar panel can be changed not only by the strong wind pressure on both ends of the solar cell, which is not supported, but also the deformation or damage of the both sides of the solar panel. Can be.

In addition, when the height of the solar panel is installed high, there is a problem that can not easily rotate the solar panel.

That is, the conventional solar panel is a rotating shaft is provided on the back of the solar panel, a method of adjusting the inclination angle of the solar panel using the rotating handle provided on the rotating shaft, when the solar panel is installed higher than the height of the human solar panel back In order to rotate the rotary handle provided on the rotary shaft of the hassle that there must be a pedestal, ladder and the like.

In addition, there is a problem that the edges of the solar panels are installed or the edges of the solar panels are dirty or damaged by the excrement discharged while the birds temporarily stay at the edges of the solar panels while not being smooth.

The present invention was devised to solve all the problems of the conventional inclination-adjustable solar power generator, and one person can easily adjust the inclination angle of the solar panel, even when the wind pressure acting on the solar panel is strong. It is an object of the present invention to provide a solar cell apparatus that can be prevented or minimized, such as a change in the inclination angle, damage or deformation of the panel.

In addition, it is another object of the present invention to provide a solar power generation device that can not easily sit and adjust the inclination angle of the solar panel without the help of a ladder, even if the solar panel is installed higher than the height of the person.

The object of the present invention is to establish a horizontal rotating shaft coupled to the base sufficiently below the base, not the back of the base on which the solar panel is mounted, a plurality of connecting members connecting the base and the rotating shaft, and the edge of the base. Is achieved by a plurality of bird control bars and the like.

The solar cell apparatus of the present invention can easily adjust the inclination angle of the solar panel by the force of one person, and even when the wind pressure imparted to the solar panel by the wind is large, a large portion of the base on which the solar panel is mounted is supported by the connecting member. Therefore, the inclination angle of the solar panel is maintained stably, and there is an advantage of preventing or minimizing deformation or damage of the solar panel and the base due to wind pressure.

In addition, since the rotating shaft is installed below the base of the base, even when the base with the solar panel is mounted higher than the height of the person, the connecting rod can be placed in a place where a person can reach the bar. There is an advantage that it is possible to easily adjust the inclination angle of the solar panel by rotating the rotating shaft without mobilizing the support means such as.

In addition, since the algae can not fly to the edge of the solar panel by the bird extinguishing bar erected on the edge of the expectation, there is an advantage that the pollution or damage of the solar panel by the bird droppings is prevented or minimized.

The present invention relates to a solar power generation apparatus, which makes it possible to easily adjust the inclination of the solar panel according to the south mid-high angle of the sun in a fixed installation state.

In the solar power generation apparatus of the present invention, a rotating shaft is coupled to a base of a plate on which a solar panel is mounted, and a rotating shaft is coupled to a lower pillar of the base, and the rotary shaft and the base are not directly connected to each other. There is a feature of the invention in the structure connected by.

That is, the solar power generator of the present invention is installed with the base and the rotating shaft spaced apart from each other in the upper and lower parts of the post, so that the length of the connecting member can be extended even when the base equipped with the solar panel is installed higher than the height of a person. If you do, you can place the axis of rotation in a place where people can easily reach it.

And unlike the conventional solar power generation apparatus in which the north-south longitudinal center portion is rotatably coupled and supported by the shore for adjusting the inclination angle, and both ends of the north-south longitudinal direction are not supported by the shore, Since both ends in the longitudinal direction can be supported, the installation state and the inclination of the base can be stably maintained even when the wind pressure acting on the base is large.

The solar power generation device of the present invention as described above, and the props erected on the floor; A base rotatably coupled to the upper end of the support; A solar panel mounted on an upper surface of the base; A rotational shaft coupled horizontally along the east-west direction so as to be rotatable to the lower post of the base; A rotating shaft driving means provided on the rotating shaft; A plurality of connecting members connecting the rotating shaft and the base; And the like.

At this time, the rotating shaft driving means for rotating the rotating shaft, a variety of forms and structures are possible, representatively, the structure of the handle is directly coupled to the outer peripheral surface of the rotating shaft, the handle having a axial direction perpendicular to the rotating shaft and a gear using a bevel gear For example, the coupling structure.

The most important idea in the apparatus of the present invention configured as described above is that the rotary shaft for rotating the base and the base is coupled to the prop in a state spaced up and down, and the rotary shaft and the base are coupled through a separate connecting member, The rotation of the rotary shaft is transmitted to the base through the connecting material.

The base and the rotating shaft are rotatable in the state of being coupled to the upper and lower parts of the support, wherein the base is rotated at both ends of the north-south direction with the center of rotation in the north-south direction as the center of rotation. When rotated in a state positioned on a horizontal plane, one of the south side and the north side of the base around the center of rotation of the base closer to the axis of rotation below the base, the other side is away from the axis of rotation.

That is, the axis of rotation rotates at a fixed position, but when the base rotates, both sides rotate around the center of rotation, where the distance between the north and south ends of the base changes and the axis of rotation changes. When the base and the rotating shaft are connected as the connecting member, the base and the rotating shaft cannot be rotated and fixed.

However, it is not possible to use a connecting material made of a flexible material whose length varies with the rotation of the base, the connecting member comprising: a horizontal connecting member fixed to both ends of the rotating shaft; A vertical connecting member whose both ends are rotatably coupled to the base and the horizontal connecting member; There is a structural feature of the present invention to constitute such.

At this time, when the base is in a horizontal state, the horizontal connecting member is parallel to the base by making a horizontal at a right angle with the rotation axis, and the vertical connecting member coupled to both ends of the base and the horizontal connecting member so as to be rotatable. It is coupled in a vertical direction to form a right angle with all the connecting members.

Therefore, the upper and lower coupling portions of the vertical connecting member and the horizontal connecting member parallel to each other and placed on the horizontal plane of the upper and lower virtual positions are positioned on the same vertical line. In this state, when the base and the rotation axis rotate by the same angle, The gap between the bottom of the base and the top of the horizontal connecting member becomes narrow.

However, since the upper and lower coupling portions of the vertical coupling member rotatably coupled to the base and the horizontal coupling member move by the same amount, the same distance can be maintained on the vertical line moved to one side.

At this time, the vertical connecting member remains vertical, but the base and the vertical connecting member and the angle between the vertical connecting member and the horizontal connecting member and the vertical connecting member are at right angles as the base and the horizontal connecting member are inclined by the rotation. Acute angle (or obtuse angle) is achieved.

The connection structure of the base, the rotating shaft, the horizontal connecting member and the vertical connecting member as described above is a case where the base with respect to the support and each rotary coupling portion of the rotating shaft is located on the same vertical line.

However, the base for the support and each rotary joint of the rotating shaft may be made so as not to be located on the same vertical line. In this case, with the base, the rotating shaft and the horizontal connecting member being horizontal, the vertical connecting member is horizontally connected with the base. It is not coupled in the direction perpendicular to the member but is coupled in an inclined direction.

At this time, the imaginary straight line connecting the base with respect to the support and the rotation center of each of the rotating shafts is parallel to the imaginary straight line (or axial direction of the longitudinal connecting member) connecting the center of rotation of both ends of the longitudinal connecting member with respect to the base. do.

That is, both ends (or upper and lower ends) of the vertical connecting member must be rotatably coupled to the base and the respective portions of the horizontal connecting member, which are separated by the same distance from each rotation center of the base and the rotating shaft, so that the rotation of the rotating shaft is horizontal It can be delivered to the base through the connecting member and the longitudinal connecting member.

At this time, the axial direction of the rotary shaft 14 is most preferably to match the east-west direction.

And the connecting member 16 for connecting the rotating shaft 14 and the base 12 is composed of a horizontal connecting member 16A and a vertical connecting member 16B, the horizontal connecting member 16A is a rotating shaft 14 Longitudinal centers are fixedly coupled to both ends of the rotational shaft 14 so as to be parallel to the base 12 in a horizontal state at a right angle to the horizontal direction, and both ends of the vertical connecting members 16B face each other along a vertical direction. To be rotatably coupled to the base 12 and the horizontal connecting member 16A, respectively.

In addition, it may be preferable to use a turnbuckle as the vertical connection member 16B. In this case, the solar panel 13 is rotated without rotating the rotating shaft 14 by reducing the length of one turnbuckle and extending the length of the other turnbuckle. ), And by using a turnbuckle it is possible to accurately adjust the level of the base 12 relative to the rotation axis 14 as needed.

At this time, each of the upper end of the plurality of vertical connection member 16B is coupled to a portion corresponding to each other 1: 1 on both sides of the rotation center of the base 12, the lower end of the vertical connection member 16B and the base It is preferable to be coupled to the portion of the opposite horizontal connecting member 16A, but it is not necessary to satisfy this condition.

According to the size of the base 12, one or more horizontal connecting members 16A may be coupled to the center between both ends of the rotating shaft 14, and the horizontal length of which is relatively short on both sides of the rotating shaft 14. There is no particular limitation on the coupling structure of the rotating shaft 14 and the horizontal connecting member 16A, such that the connecting members 16A may be coupled to one another or staggered with each other.

However, bird droppings are acidic, which not only pollutes the surrounding environment but also causes corrosion of the device, and when the bird droppings are on the surface of the solar panel, the solar cell does not produce electricity. It is preferable to establish a plurality of bird elimination bar 17 at the edge of the base 12 so that birds do not sit on.

The spacing between the bird elimination bar 17 depends on the type of bird, the bird is not sitting because the two bird elimination bar 17 interferes with the wing of the bird.

At this time, in the state in which the base plate 12 on which the solar panel 13 is mounted is inclined, it may be difficult for the bird to sit on the lower end of the base plate 12 and the inclined sides of the base plate 12. Although it may be erected on the entire edge of the base 12 to be installed, one side of the edge, that is, the base 12 may be installed only on the upper part in the inclined state, optionally installed only on a part of the entire edge of the base as needed May be
