Description

Solar energy module having non-power waste remover, and sun location tracking apparatus of solar heat or photovoltaic collectors having the Same}

The present invention relates to a solar energy module having a non-powered foreign matter removal unit, and a solar collector or a solar position tracking device of the solar collector having the same, and more particularly, to be easily installed to have a simple and simple structure. Of course, it is possible to remove the foreign matter remaining on the surface of the solar module while operating without power without a separate power source, and as a result, a solar energy module having a non-powered foreign matter removal unit that can be expected to improve the amount of solar power generation, and It relates to a solar position tracking device provided with a solar collector or a solar collector.

Due to the depletion of chemical energy such as coal and petroleum and environmental pollution due to the use of chemical energy, efforts are being made to develop alternative energy. One of them is photovoltaic power generation using solar energy. Photovoltaic power generation is a technology that converts solar energy into electrical energy.

Briefly, the basic principle is that when solar light is irradiated to a solar cell composed of a pn junction semiconductor, electron and hole pairs are generated by light energy, and electrons and holes move across the n and p layers. The electromotive force is generated by the photovoltaic effect through which the current flows, and the result of the current flowing to the externally connected load is used.

In this way, in order to convert the solar energy without pollution into electrical energy, above all, development of a technology for collecting solar heat or collecting solar light by tracking the position of the sun is required. That is, since the position of the sun continuously changes according to rotation and revolution, a solar collector or a solar position tracking device of a solar collector is required as a means for collecting and concentrating a larger amount of solar energy per unit time.

The solar position tracking device of a solar collector or solar collector, which is known or already in commercial preparation, supports a number of solar energy modules for collecting or concentrating solar energy (including solar and solar light), and solar energy modules. A plurality of torque tubes, a support for supporting the torque tubes with respect to the ground, a drive strut coupled to the plurality of torque tubes to rotatably support the plurality of solar energy modules, and being fixed to each other; Torque arms and a drive unit for driving the drive strut and the torque arm. Accordingly, when the drive unit is operated to drive the drive strut and the torque arm, the solar energy module rotates in conjunction with the drive unit to collect solar energy.

On the other hand, the solar module is installed in the outdoor space due to the nature of converting the radiant energy of the sun into electrical energy. In order to produce a large amount of electrical energy per unit area, it is common to install as many large solar modules as possible in a given space.

However, when the solar energy module is installed in the outdoor space as described above, foreign matters such as sand or dust come into contact with the surface of the solar energy module, thereby causing the surface of the solar energy module to be contaminated. In particular, if the solar module is installed in a place such as a sandy windy desert, this problem will be doubled.

On the other hand, the surface of the solar module is generally made of glass (glass may be common or plastic) to absorb the sun's radiant energy. When the surface of the solar module is contaminated, the radiant energy is reflected or absorbed. Since the amount of radiant energy can only be reduced, the result is a loss of solar power.

Therefore, the solar energy module is installed with a rather complicated structure such as an electric motor as a power source, a power transmission device operated by the power of the electric motor, and a foreign material removal brush connected to the power transmission device to substantially remove foreign materials. Consideration can be given to removing foreign matter that may remain on the surface of the energy module.

However, given the fact that dozens or hundreds of solar modules are installed in a large outdoor space instead of just a few solar modules to produce electrical energy, a complex structure is difficult to install, especially an electric motor. The use of a separate power source and the removal of foreign matter remaining on the surface of the solar module based on the artificial on / off operation of the electric motor will be less effective and difficult to commercialize. Is required.

The object of the present invention is that it can be easily installed to have a simple and simple structure, as well as to remove foreign substances remaining on the surface of the solar module while operating without power without a separate power source, resulting in improved solar power generation. It is to provide a solar energy module having a non-powered foreign matter removal unit that can be expected, and the solar position tracking device of the solar collector or solar collector having the same.

It is achieved by a solar energy module having a non-powered foreign matter removal unit.

Here, the non-powered foreign material removal unit, the foreign material removal member for the exposed end is in contact with the surface of the solar module module to remove the foreign material; And a moving support for movably supporting the foreign material removing member with respect to the solar energy module main body such that the foreign material removing member moves along the surface of the solar energy module main body.

The moving support may include a rail provided on a side wall of the solar energy module body; And the foreign matter removal member is detachably coupled, the end is coupled to the rail may include a slider for sliding the rail along the longitudinal direction.

A sliding moving member sliding along the rail on the rail may be further coupled to an end of the slider.

The slider may include a sliding horizontal bar coupled to the foreign material removing member and disposed parallel to the surface of the solar module module; And a sliding vertical bar bent in a direction crossing the longitudinal direction of the sliding horizontal bar at an end of the sliding horizontal bar.

The rail may further include a sliding movement blocking groove for temporarily preventing the sliding movement of the sliding movement member when the rotation angle of the solar energy module body is smaller than a predetermined angle.

The sliding movement blocking groove may be processed into an arc shape.

The rails may be provided symmetrically on both side walls of the solar energy module body.

The rail may be separately coupled to a frame forming an outer edge of the solar energy module body.

The rail may be integrally formed with a frame forming an outer edge of the solar energy module body.

In the drawings, the support 10 is shown as a rod-type of a cross-section circular shape, but the scope of the present invention is not limited thereto.

The torque tubes 20, 50, and 60, that is, the first to third torque tubes 20, 50 and 60, which are coupled to the support 10 in a rotatable manner, are solar modules for collecting or concentrating solar energy. It is a part which supports (3) rotatably. In this embodiment, three (three rows) of the first torque tube 20, the second torque tube 50, and the third torque tube 60 are disclosed along the X-axis direction of FIG. 1.

However, since the scope of the present invention is not limited thereto, four (four rows) along the X-axis direction of FIG. 1 in addition to the three (three rows) of the first to third torque tubes 20, 50, and 60. The above torque tubes may be provided, and in some cases, only two (two rows) of the first and second torque tubes 20 and 50 may be provided.

The solar energy module 3 of the present embodiment collects solar heat when solar energy is solar heat, and collects solar light when solar energy is solar light. Of course, as will be described later, in the present embodiment, since the solar energy module 3 must move according to the position of the sun, the solar energy module 3 of the present embodiment mainly serves to condense sunlight, It may be applied or used as a means of collecting.

For reference, the solar energy module 3 refers to a solar cell module made of a rigid material and structure that can withstand climate after solar cells composed of pn junction semiconductors are connected in series or in parallel. However, since the scope of the present invention is not necessarily limited thereto, the surface of the solar module 3, that is, the surface of the solar module main body 5 may be glass, as described above, but plastic, in particular, convex. It may be a lens.

The first to third torque tubes 20, 50 and 60 in this embodiment are made of square steel pipes. This is only an example of the rectangular steel pipe considering that the first to third torque tubes (20, 50, 60) is a member directly coupled to the solar energy module 3, the torque tube for supporting the solar energy module (3) There is no limitation on the shape as long as it can function as.

Considering that the solar position tracking device 1 of the solar collector or the solar collector according to the present embodiment is installed in a sparse and spacious space, the first to third torque tubes 20, 50, 60 are Long lengths should be used. However, it is not easy to manufacture a steel pipe with an infinite length in production.

The driving unit 30 serves to directly drive and rotate the first torque tube 20 among the first to third torque tubes 20, 50 and 60. The driving unit 30 includes a first torque arm 31 coupled to the first torque tube 20, and a driving unit 33 connected to the first torque arm 31 to rotate the first torque tube 20. ).

The first torque arm 31 is coupled to the first torque tube 20 in a direction crossing the longitudinal direction of the first torque tube 20, and the first torque tube 20 when the drive unit 33 operates. Together they make some rotational movements about the ground.

The drive part 33 is a structure which directly rotates the 1st torque arm 31. FIG. The first torque arm 31 is rotated by the driving of the driving unit 33, and thus the first torque tube 20 may be rotated.

As shown in FIG. 1, the driving unit 33 is disposed between the first torque tube 20 and the second torque tube 50. However, since the scope of the present invention is not limited thereto, the driving unit 33 may be disposed between the second torque tube 50 and the third torque tube 60.

As such, as the driving unit 33 is disposed between the first torque tube 20 and the second torque tube 50, the area loss and structural constraints caused by the use of a conventional driving unit (not shown) are properly adjusted. It can be solved. That is, in the related art, due to the structure in which the driving unit 33 may not be disposed between the first to third torque tubes 20, 50, and 60, an area loss and structural constraints have occurred. However, in this embodiment, the driving unit 33 is the first torque tube 20 and the second torque tube 50 by the organic mechanism of the first interlocking connection unit 40 and the second interlocking connection unit 70 which will be described later. By being able to be disposed between) it is possible to solve the conventional problems. In the present embodiment, the drive unit 33 is provided as a tracker including a screw jack 35 for pushing or pulling the first torque arm 31, but is not necessarily limited thereto.

When the first torque tube 20 is rotated by the driving unit 33, the first interlocking connection unit 40 is adjacent to the first torque tube 20 in cooperation with the rotation of the first torque tube 20. 2 is a structure for connecting the first torque tube 20 and the second torque tube 50 so that the torque tube 50 rotates.

The second interlocking connection unit 70 serves to allow the third torque tube 60 to be organically rotated in association with the rotation of the first torque tube 20. The second interlocking connection unit 70 has a first torque arm 31 of the first torque tube 20 so that the third torque tube 60 can rotate in conjunction with the rotation of the first torque tube 20. And a third torque arm 61 coupled to the third torque tube 60. The second interlocking connection unit 70 is coupled to the lower end of the first torque arm 31 and one end of the screw jack 35 at one end, and the lower end coupled to the lower end of the third torque arm 61 at the other end. The connecting shaft 71 is provided.

When the first torque arm 31 is rotated by the screw jack 35 of the driving unit 33, the second interlocking connection unit connected to the lower end of the first torque arm 31 and one end of the screw jack 35 ( The lower connection shaft 71 of the 70 is also organically operated based on the first torque arm 31 and rotates the third torque tube 60 to couple the solar energy module 3 coupled to the third torque tube 60. Will be able to rotate.

Meanwhile, the solar energy module 3 is coupled to the first to third torque tubes 20, 50, and 60, respectively, in a state in which rotation is prevented by the module rotation preventing unit (not shown).

For reference, a fourth or more torque tube (not shown) including a second torque tube 50 and a third torque tube 60 to be arranged in the X-axis direction in which the solar energy module 3 is continuously arranged, although not shown in the drawing, is illustrated. Module rotation stopping units (not shown) provided in the) is also the same as the module rotation blocking unit (not shown) described above, and the description and description thereof will be omitted.

The module rotation preventing unit (not shown), in addition to the role of coupling the solar energy module 3 to the first torque tube 20, in particular, any rotation of the solar energy module 3 coupled to the first torque tube 20. It serves to block. Here, the arbitrary rotation means that the solar energy module 3 rotates in the forward and reverse directions on the ground.

Meanwhile, hereinafter, FIGS. 2 to 7 illustrate a non-powered foreign matter removing unit 100 partially coupled to the solar energy module 3 to remove foreign matter remaining on the surface of the solar energy module main body 5 as described above. This will be described with reference.

Figure 2 is an enlarged view of the main portion of Figure 1, Figure 3 is a partially enlarged view of "A" of Figure 2, Figure 4 is a perspective view of the main portion of the non-powered foreign material removal unit, Figures 5 to 7 are each shown in Figure 1 Figures showing the operation of the non-powered foreign matter removal unit according to the operation of the solar collector or the solar position tracking device of the solar collector.

2 to 4, the solar energy module 3 according to the present embodiment is partially coupled to the solar energy module main body 5 and the solar energy module main body 5. It includes a non-powered foreign matter removal unit 100 for removing the foreign matter remaining on the surface of the solar energy module main body 5 while operating in a non-powered in conjunction with the rotational motion of the energy module main body (5).

The surface of the solar module main body 5 may be a conventional glass or convex lens as described above in the solar collector or the solar position tracking device of the solar collector, or may be provided in plastic. The surface of the solar module main body 5 in this embodiment is glass.

In the non-powered foreign matter removing unit 100 for removing the foreign matter remaining on the surface of the solar energy module main body 5, the exposed end exposed to the surface side of the solar energy module main body 5 is the surface of the solar energy module main body 5. The foreign material removing member 110 to remove the foreign material while being in contact with the foreign material removing member 110 and the foreign material removing member 110 so as to slide on the surface of the solar module main body 5. It includes a movable support 130 to support the movable.

Prior to the description of the foreign material removing member 110, the moving support 130 of the non-powered foreign material removing unit 100 will be described with reference to the rail 131 provided on the side wall of the solar module main body 5. In addition, the foreign material removing member 11 is detachably coupled, the end is coupled to the rail 131 includes a slider 133 which is slidably moved along the longitudinal direction of the rail 131.

The slider 133 has a sliding horizontal bar 133a coupled to the foreign material removing member 110 and disposed parallel to the surface of the solar module main body 5, and a sliding horizontal bar 133a at the end of the sliding horizontal bar 133a. Sliding vertical bar (133b) is bent in the direction crossing the longitudinal direction of the).

The sliding horizontal bar 133a of the slider 133 is generally formed in the shape of a rectangular parallelepiped or a cylindrical long rod, but this type of the sliding horizontal bar 133a is not limited thereto but may be formed in various forms. In this embodiment, it is formed in the shape of a long rod of a rectangular parallelepiped.

In the sliding horizontal bar 133a, a coupling groove (not shown) is formed at one side facing the solar energy module main body 5, and the foreign material on the surface of the solar energy module main body 5 is removed in the coupling groove (not shown). The foreign material removing member 110 may be combined. Since the foreign material removing member 110 that is heavily soiled or worn at the end should be removable, the foreign material removing member 110 may have a structure that is easily detached and coupled to a coupling groove (not shown) of the sliding horizontal bar 133a.

The slider 133 is further coupled to both ends thereof a sliding moving member 135 which is slidably moved along the rail 131 on the rail 131. The sliding moving member 135 may be slidingly moved along the rail 131 on the rail 131 as a plastic injection molding.

However, since the scope of the present invention is not limited thereto, a non-motor rolling wheel (not shown) may be applied as a sliding moving member 135, which is cloudlessly moved along the rail 131 on the rail 131. In this case, the non-powered rolling wheel may be coupled to the rail 131 so as to be able to move in a rolling state coupled to the end of the sliding vertical bar (133b), bearing between the non-powered rolling wheel and the sliding vertical bar (133b) It is better to intervene (not shown) to allow smooth rotation of the non-powered rolling wheel. Of course, even if there is no bearing, the non-powered rolling wheel can be sufficiently clouded in conjunction with the rotational motion of the solar module main body 5, but if the bearing is interposed between the non-powered rolling wheel and the sliding vertical bar (133b) The rolling movement of the moving wheel is much smoother, and the friction between the non-powered rolling wheel and the sliding vertical bar 133b may be minimized.

The sliding vertical bar 133b, which is bent in a direction crossing the longitudinal direction of the sliding horizontal bar 133a at both ends of the sliding horizontal bar 133a and the sliding moving member 135 is coupled as described above, is a sliding moving member ( The size of the cross-section combined with the 135 is larger than the sliding moving member 135 to prevent the sliding moving member 135 from being separated from the rail 131 and to prevent dust and contaminants from sliding from the outside. It is effective to block the inflow to).

The rails 131 are provided symmetrically on both side walls of the solar module main body 5. After the rail 131 is manufactured separately, the rail 131 may be further coupled to a frame (not shown) forming an outer edge of the solar module main body 5, or a frame forming an outer edge of the solar module main body 5. It may be formed integrally with. The former may be advantageous if the solar module main body 5 is already manufactured, and the latter may be advantageous if the solar module main body 5 is being manufactured.

In this embodiment, the rail 131 is formed integrally with the frame forming the outer edge of the solar module module 5, the sliding movement member 135 on the two outer surface symmetrical of the four sides of the frame ) Is provided by forming the groove 131 ′ which is openable to engage.

 On the other hand, the sliding moving member 135 is a sliding movement along the rail 131 based on the inclination of the solar module main body 5 during the rotation of the solar module main body 5 causes the foreign material removing member 110 to solar energy Remove foreign substances from the surface of the module main body (5). In this case, in the state where the rotation angle of the solar energy module main body 5 is the largest, for example, 45 degrees, the foreign material removal member 110 causes the solar energy module main body 5 to slide quickly and quickly. It is good for efficiency to remove the foreign material of the surface.

Otherwise, even though the rotation angle of the solar energy module main body 5 is relatively small, when the sliding movement member 135 slides, the sliding movement speed of the sliding movement member 135 is too slow or stops in the middle. It is highly likely to reduce the efficiency of foreign matter removal as a result.

In order to prevent this phenomenon, the rail 131 has a sliding movement blocking groove 131a which temporarily blocks the sliding movement of the sliding movement member 135 when the rotation angle of the solar module main body 5 is smaller than the predetermined angle. ) Is prepared.

As described above, the sliding movement blocking groove 131a is provided to temporarily prevent the sliding movement of the sliding movement member 135 and may be processed into an arc shape.

This temporarily stops the sliding movement of the sliding movement member 135 until the rotation angle or the inclination of the solar energy module main body 5 capable of the sliding movement blocking groove 131a becomes a predetermined value, for example, 45 degrees. This is because it is difficult to prevent the sliding movement of the sliding member 135 even though the rotation angle of the solar module main body 5 has become the maximum inclination.

Therefore, in the present embodiment, the sliding movement blocking groove 131a is processed into an arc shape. In this case, the diameter of the sliding movement blocking groove 131a may be smaller than the diameter of the sliding movement member 135. As such, the size of the diameter of the sliding movement blocking groove 131a is smaller than the diameter of the sliding movement member 135, which is advantageous for temporarily preventing the sliding movement of the sliding movement member 135.

However, the scope of the present invention need not be limited thereto. That is, the sliding movement of the sliding movement member 135 is prevented until the rotation angle and the slope of the solar energy module body 5 are smaller than a predetermined value, and then the sliding movement of the sliding member 135 is slid at a predetermined angle, that is, the maximum angle, for example, an angle of 45 degrees. If only the sliding movement of the moving member 135 can be allowed, the sliding movement stopping groove 131a may be deformed in various sizes or depths, and also in shape or shape, out of the arc shape shown.

On the other hand, the foreign material removing member 110 in contact with the surface of the solar module main body 5 to remove foreign substances on the surface of the solar energy module main body 5 may be used in various ways, such as a vehicle cleaning brush or a wiper rubber for cleaning the vehicle glass. Can be prepared. However, when the wiper rubber for washing the vehicle glass is used as the foreign material removing member 110, the brush may be selected as the foreign material removing member 110 in this embodiment because the smooth operation may not be performed by the frictional force.

Hereinafter, the operation of the solar position tracking device of the solar collector or the solar collector as described above with reference to FIGS. 5 to 7, and the operation of the non-powered foreign matter removal unit 100 in conjunction with this will be described.

5 to 7, since the solar energy module main body 5 is preferably disposed in a direction inclined to be orthogonal to orthogonal to the irradiation direction of sunlight shining from the east direction, the first torque arm 31 is provided. And the third torque arm 61 are positioned while forming a constant angle with respect to the ground. Looking at the operation, as the screw jack 35 of the drive unit 33 is operated by moving backward by a predetermined length, the first torque arm 31 is inclined as shown in FIG.

As such, the first to third torque tubes 20, 50, and 60 are rotated by the operation of the driving unit 33, so that the solar energy module body coupled to the first to third torque tubes 20, 50, and 60 is rotated. 5 is rotated in an inclined direction as shown in FIG. 5, and thus is aligned to be orthogonal to the irradiation direction of sunlight shining from the east direction, so that a large amount of solar energy can be collected or collected.

When the solar energy module body 5 is rotated as shown in FIG. 5, the non-powered foreign matter removal unit 100 is operated in conjunction with this. That is, the foreign matter removing member 110 of the non-powered foreign matter removing unit 100, which is partially coupled to the solar energy module main body 5, is moved in the direction of the solid arrow from the dotted line in conjunction with the rotational movement of the solar energy module main body 5; The foreign substance remaining on the surface of the solar module main body 5 is removed. At this time, the foreign material removing member 110 is located on the side facing the ground.

6, when the sun is positioned at noon as shown in FIG. 6, as the screw jack 35 of the driving unit 33 moves forward by a predetermined length, the first torque arm 31 is substantially up and down as shown in FIG. 6. It is arranged perpendicular to the direction.

When the first torque arm 31 rotates, at the same time, the second and third torque tubes 50 and 60 are also connected to the first torque tube by the first interlocking connection unit 40 and the second interlocking connection unit 70. By being rotated in coordination with 20), the angle of the solar energy module main body 5 is maintained in a horizontal state while being aligned to be orthogonal to the irradiation direction of sunlight shining at noon.

And the position of the non-powered foreign matter removal unit 100 at this time is not significantly different from before the sun is located at noon. The solar module main body 5 has been rotated so as to be horizontal to the ground due to the rotation of each torque arm according to the positional movement of the sun, but the inclination of the non-powered foreign matter removal unit 100 is not changed. The non-powered foreign matter removal unit 100 does not move.

On the other hand, the non-powered foreign material removal unit 100 is a sliding movement blocking groove formed in the rail 131, although the non-powered foreign material removal unit 100 may be moved to a minute degree due to the vibration caused by the rotation of the solar module main body 5 ( Since 131a is formed, the non-powered foreign matter removing unit 100 does not move in a direction opposite to the initial position.

When the sun is located in the approximately west direction as time elapses again, it is preferable that the solar energy module main body 5 is arranged in a direction which is inclined at a constant angle so as to be orthogonal to the irradiation direction of sunlight shining from the west direction. Therefore, the first torque arm 310 is positioned while forming a constant angle with respect to the ground.

Looking at the operation, as the screw jack 35 of the drive unit 33 is advanced by a predetermined length of operation, the first torque arm 31 is disposed inclined as shown in FIG. At the same time, the third interlocking connection unit 70, which is connected to the lower end of the first torque arm 31 and one end of the screw jack 35, is also organically operated based on the first torque arm 31. By rotating the 60, the third torque tube 60 also rotates in coordination with the first torque tube 20.

As such, the first to third torque tubes 20, 50, and 60 are rotated by the operation of the driving unit 33, so that the solar energy module body coupled to the first to third torque tubes 20, 50, and 60 is rotated. 7 is rotated in an inclined direction as shown in FIG. 7, and thus is aligned so as to be orthogonal to the irradiation direction of sunlight emitted from the west direction, so that a large amount of solar energy can be collected or collected.
