Description

BIPV type solar power window module {PHOTOVOLTAIC WINDOW MODULE OF BIPV TYPE CAPABLE OF ANGLE CONTROL}

The present invention relates to a window module having a solar cell panel, and more particularly, to a window module for a solar power generation system having a BIPV type module.

The use of various renewable energy sources such as solar power, wind power, wave power, and geothermal heat is increasing in order to solve environmental and cost problems caused by energy production using fossil fuels or nuclear power.

Among them, solar power generation has the advantages of having fewer restrictions on the installation site compared to other renewable energy sources such as wind power, relatively simple construction, and easy adjustment of the power generation scale, so it is easy to apply it using residential spaces such as houses or apartments. can see.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

1 is a front view of an embodiment of a solar power window module of the present invention. 2 is a side view of one embodiment of a solar power window module of the present invention;

The BIPV photovoltaic window module of the present invention includes a frame portion 10 and a link portion 20 comprising a pair of links 20A and 20B that are rotatably installed on both sides of the frame portion 10 inside. , and a solar panel unit 30 comprising a plurality of solar panels 31 hinged for each of the links 20A and 20B.

The frame portion 10 is formed in a substantially rectangular shape and a pair of frame pin portions 11 protruding in the width direction from both side frames in the front view are formed.

The frame pin portion 11 is positioned approximately in the middle of the side frame and is formed to have a rectangular cross-section.

A pair of rod-shaped frame stoppers 12 extending in the width direction are installed in the middle upper portion of the frame part 10 .

On the other hand, when the frame part 10 is installed as an outer wall of a new building itself for BIPV use, the flat glass 13 may be installed at the front end of the frame part 10 .

Each link (20A, 20B) is formed in a rod shape, and the inside of the link (20A, 20B) is a panel pin portion receiving portion 22 so as to be hinged with the panel pin portion 32 of each solar panel 31 in the height direction. ) is formed in plurality.

In the photovoltaic panel unit 30 , a plurality of photovoltaic panels 31 are arranged in a height direction, and a general photovoltaic panel of a known configuration is used as the photovoltaic panel 31 .

A panel fin part 32 is formed in the middle in the height direction on both sides of each solar panel 31 , and a link fin part receiving part 33 having a groove formed thereon is formed behind the central part of the upper end.

The first torsion unit 40 is installed outside the position where the uppermost solar panel 31 is installed in each of the links 20A and 20B.

Figure 3 is a view showing a torsion unit in one embodiment of the solar power window module of the present invention.

The first torsion unit 40 is basically made of a first torsion rubber 42 having a rectangular first receiving groove 41 formed therein.

The first torsion part 40 is formed to form a square pipe 43 on the outside of the receiving groove 41 or to add a cylindrical housing 44 integrally formed on the outside of the torsion rubber 42 as necessary. can be

The stopper link unit 50 includes a pair of stopper links 50A and 50B installed at the rear of the solar panel 31 installed at the uppermost end.

Each stopper link (50A, 50B) has a width direction extension 51 extending in the width direction to the inner rear surface of the solar panel 31, and the uppermost solar panel 31 in the width direction extension portion 51. ), a height direction extension part 52 extending downward in the height direction, and a stopper pin part installed under the height direction extension part 52 and inserted into the receiving groove 41 and having a rectangular cross section. (53) consists of

Since the stopper pin part 53 is inserted and fastened into the first receiving groove 41 of the first torsion part 40, each stopper link 50A, 50B is connected to each link 20A, 20B.

A second torsion unit 60 is installed at a position where the frame pin unit 11 is formed in each of the links 20A and 20B.

The second torsion unit 60 is also made of a second torsion rubber 62 having a rectangular second accommodating groove 61 formed therein, similarly to the first torsion unit 40 , and, if necessary, a second accommodating groove 61 . ) may be formed to form a square pipe 63 on the outside or to add a cylindrical housing 64 integrally formed on the outside of the torsion rubber 62 .

However, the elastic modulus of the second torsion rubber 62 is formed to be smaller than the elastic modulus of the torsion rubber 42 of the first torsion part 40 , so that the deformation rate is greater in the second torsion part 60 .

That is, the first torsion unit 40 is configured to be more easily deformed than the second torsion unit 60 .

A guide link 70 is installed in the height direction from the center of each solar panel 31 , and each guide link 70 is a link pin portion hinged with the link pin portion receiving portion 33 formed in each solar panel 31 . (71) is formed.

On the other hand, an actuator 80 is installed on the upper portion of the frame portion 10 to press the solar panel 31 located at the uppermost end.

The actuator 80 includes a cylinder 81 containing a working fluid f and a plunger 82 operated by the working fluid f.

The driving method of the actuator 80 may be formed by a known electric type, hydraulic type, etc. operated by a driving source (not shown) such as a motor.

Alternatively, when the working fluid f filled in the rear of the plunger 82 inside the cylinder 81 is used as the working fluid f with a high coefficient of thermal expansion that expands according to the outside temperature, the working fluid f Since it becomes possible to drive the plunger 82 by thermal expansion, it becomes possible to operate the actuator 80 without a separate driving source.

Next, the operation of the photovoltaic window formed in this way will be described.

5 is a view showing the first step of angle adjustment in an embodiment of the solar power window module of the present invention.

When the actuator 80 is not operated, the photovoltaic window remains in the state of FIG. 2 .

In the first step of adjusting the solar panel angle, as shown in FIG. 5 , when the actuator 80 is driven, the upper part of the uppermost solar panel 31 is pressed while the uppermost solar panel 31 is centered on the panel fin part 32 . As seen from the side, it rotates counterclockwise, and the rotation is stopped by the width direction extension part 51 of the stopper link 50 installed at the rear of the uppermost solar panel 31 .

As the panel pin part 32 of the uppermost solar panel 31 rotates, the photovoltaic panel 31 rotates and the link pin part accommodating part 33 also rotates while moving downward and connected to the link pin part accommodating part 33. The guide link 70 moves downward.

Due to the downward movement of the guide link 70, all the solar panels 31 combined with the guide link 70 rotate counterclockwise to form an angle.

Figure 6 is a view showing the second step of angle adjustment in an embodiment of the solar power window module of the present invention.

In the second step of adjusting the angle of the solar panel, as shown in FIG. 6 , when the actuator 80 is further driven, the uppermost panel 31 is further rotated together with the stopper link 50 and a pair of link units 20 are It rotates around the frame pin part 11 .

The pair of link units 20 are rotated while the rotation is stopped by the frame stopper 12 .

The reason why the pair of link units 20 rotate around the frame pin unit 11 instead of the stopper pin unit 53 is as follows.

In the first torsion part 40 in which the stopper pin part 53 is installed, the elastic modulus of the first torsion rubber 42 is formed to be greater than the elastic modulus of the second torsion rubber 62 in the second torsion part 60, This is because the deformation rate of the second torsion rubber 62 becomes larger and elastically deforms before the first torsion rubber 42 .

Accordingly, in the second step of angle adjustment, the link portion 20 is further rotated, thereby making it possible to increase the angle of the solar panel portion 30 compared to the first step of angle adjustment.

7 is a view showing three steps of angle adjustment in one embodiment of the solar power window module of the present invention.

In the third step of adjusting the angle of the solar panel, when the actuator 80 is further driven, the topmost solar panel 31 rotates further while the pair of link units 20 are fixed by the frame stopper 12. do.

As the guide link 70 is moved further downward by the rotation of the uppermost solar panel 31, the entire solar panel 30 is further rotated.

Therefore, in the third step of angle adjustment, although the link portion 20 is in a fixed state, the solar panel portion 30 is additionally rotated to increase the angle of the solar panel portion 30 compared to the second step of angle adjustment. thing becomes possible

That is, in the present invention, it is possible to adjust the angle of the solar panel 30 in three stages by driving the actuator.

Therefore, in the present invention, the photovoltaic panel can be adjusted in three stages, so that the solar power generation efficiency is improved by adjusting the angle of the photovoltaic panel to correspond to the mid-high altitude of the sun.

In particular, in the photovoltaic window module of the present invention, the angle of the photovoltaic panel unit 30 is further rotated in a state in which the link unit 20 is fixed in rotation by the frame stopper 12 in the third step of angle adjustment.

That is, it has the advantage that it is possible to maximize the angle of the solar panel in the interior of a certain thickness in the depth direction, and this advantage does not occupy a lot of indoor space when the window module is installed indoors or on the exterior wall of the building have

These advantages have greater meaning when considering the possibility that the standard of solar power generation windows can be developed into modularization for BIPV in the future.

When the plunger 82 is retreated again by controlling the driving force of the actuator 80 , the solar panel unit 30 is restored to its original angle by the elastic restoring force of the first torsion rubber 42 and the second torsion rubber 62 . will do

On the other hand, when a working fluid having a high coefficient of thermal expansion is used as the working fluid in the actuator 80 , it is possible to adjust the angle of the solar panel 30 without a separate driving source.

It is preferable to lay the angle of the vertically arranged solar panel unit 30 in the summer when the sun's mid-high altitude is high. In the summer, the outdoor temperature is generally high.

Therefore, the working fluid f with a high coefficient of thermal expansion filled in the front of the plunger 82 expands at a high temperature, so the plunger 82 moves to the rear of the window module and rotates the solar panel unit 30 to generate the sun. It acts to lay down the light panel unit 30 .

Conversely, in the case of the winter solstice when the sun's mid-solar altitude is low, it is preferable not to lay down the installation angle of the solar panel part 30 much, but since the outside air temperature is generally low, the working fluid (f) is contracted so that the plunger 82 is closed to the window. By moving to the front of the module, the photovoltaic panel unit 30 acts as a room “‡ in which it is erected again.

Therefore, even without a separate control unit, it is possible to control the angle of the solar panel unit 30 by itself according to the temperature of the season.

8 is a view showing a state in which the solar power window module of the present invention is installed in an existing building. 9 is a view showing a state in which the solar power window module of the present invention is installed in a new building.

On the other hand, since the photovoltaic window module of the present invention is formed in a modular manner through a frame as shown in FIG. 8 , it is possible to install it in the inner space of a window frame installed inside in the case of an existing building.

When additionally installed in an existing building, it is preferable to install it under the field of view to prevent the view from being blocked by the solar panel part of the window module.

In addition, in the case of a new building, as shown in FIG. 9 , by forming the window module in which the glass 13 is installed in front of the window module from the beginning as the outer wall of the building, it is constructed in an integrated BIPV method in a building having an outer wall of glass windows It has the effect of making it possible.
