Description

Solar power type roll blind with improved power generation efficiency

The present invention relates to a solar power-type roll blind with improved power generation efficiency, and more specifically, a double-layered roll-type curtain composed of a light-transmitting part and a power-generating part is configured to perform power generation while controlling the sunshade desired by the user. It relates to a solar power type roll blind with improved power generation efficiency.

Recently, as the depletion of existing energy resources such as petroleum and coal is predicted, interest in renewable energy to replace them is increasing, and solar power generation that generates electrical energy from solar energy is drawing attention.

Accordingly, energy-saving eco-friendly buildings are in the spotlight, and in order to construct such buildings, efforts to reduce the consumption of electric energy are required. In other words, as part of these efforts, attempts are being made to supplement the generated energy with the energy consumed by buildings by implementing a photovoltaic function on blinds that simply served to block light.

For example, Republic of Korea Patent Publication No. 10-1256638 (invention name: solar power blinds) and Republic of Korea Patent Registration No. 10-1470119 (invention name: blind type solar power generation device and control method) are proposed. . According to the proposed document, it is possible to reduce energy consumption due to the use of electric energy by providing not only a sunshade function but also a power generation function, and to help operate an energy-saving eco-friendly building.

However, in the case of the former, since the solar panel covers the entire window for power generation, the amount of light transmitted through the room cannot be controlled, thereby blocking the entire room. On the contrary, in the latter case, it was possible to control the motor to move the solar panel independently in a predetermined pattern for opening or mining.

However, since an expensive motor needs to be configured for each solar panel, there is a problem in that purchase or construction costs are increased, and there is a problem in that it is difficult to control and maintenance is not practical.

The present invention was created to more actively solve the above-mentioned problems, and a double-layered roll-type curtain composed of a light-transmitting light-transmitting sheet and a photovoltaic power-generating sheet is provided, and the user desires the power along with power generation. In addition, the solar panel roll blind with improved power generation efficiency can be maximized to maximize the overall power generation efficiency by inducing the angle of the power generation sheet to be varied according to the illumination of the sun with only the control panel that induces straight unfolding of the curtain. I'm trying to do that.

In order to achieve the above problem, the configuration of the solar power type roll blind with improved power generation efficiency proposed in the present invention is as follows.

Hereinafter, with reference to the accompanying drawings, the configuration of the present invention and the effects and effects thereof will be collectively described.

Advantages and features of the present invention, and methods for achieving them will be clarified with reference to embodiments described below in detail together with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, and may be implemented in various different forms, and only the present embodiments allow the disclosure of the present invention to be complete, and common knowledge in the technical field to which the present invention pertains. It is provided to completely inform the person having the scope of the invention, and the present invention is only defined by the scope of the claims. And throughout the specification, the same reference numerals refer to the same components.

The present invention relates to a solar power type roll blind with improved power generation efficiency, and the power generation efficiency with the power generation efficiency of which is mainly composed of the main body 10, the curtain 20, and the control plate 30 as shown in FIGS. 1 and 2 is improved. It is a roll blind (100).

The blind of the present invention is composed of a double layer of a roll-type curtain composed of a light-transmitting light-transmitting sheet and a photovoltaic power-generating sheet. The main point is to minimize the production cost while maximizing the overall power generation efficiency by inducing the angle of the sheet to be varied according to the illumination of the sun.

The main body 10 is installed horizontally at the top of the window to embed the curtain 20 and the control plate 30, and is largely composed of the frame 11 and the roller 15 as shown in FIGS. 1 and 2. The frame 11 is a profile having a length corresponding to at least the width of the window, and the roller 15 is rotatably embedded in the frame 11 while the curtain 20 is wound.

In the frame 11, a cover piece 11a extending toward the indoor side is integrally formed, and at one inner side, a connecting groove 11b fixing one end of the curtain 20 is formed, and at the top, it is formed on a wall or ceiling of a window. A fitting groove 11c is formed to induce detachment of the bracket (not shown) to be fixed.

And the closing piece 12 for concealing the roller 15 is fastened to both sides of the frame 11. Inside the closing piece 12, a rotating shaft 13 for fixing the roller 15 to be rotated is interposed, and a driving wheel 14 is attached between the closing piece 12 on one side and the rotating shaft 13. The driving wheel 14 is connected to the operation line 14a to receive the rotational force from the user to rotate the roller 15.

The roller 15 is interposed in the rotating shaft 13 and a winding groove 15a is formed on the outer surface to fix the other end of the curtain 20. That is, as shown in FIGS. 3 and 4, one end of the curtain 20 is fixed to the connecting groove 11b, and the other end is wound on the outer surface of the roller 15 while being fixed to the winding groove 15a. Therefore, the curtain 20 is unfolded in the U shape by the rotation of the roller 15 and unfolded in a double layer.

The curtain 20 is a membrane that selectively shades sunlight, and is composed of a light-transmitting sheet 21 and a power-generating sheet 25 as shown in FIGS. 1 and 2. The light-transmitting sheet 21 is a portion through which light is transmitted and is formed of a fabric or a transparent resin plate. And the power generation sheet 25 is composed of flexible battery cells that block light and convert it into electrical energy. The light-transmitting sheet 21 and the power-generating sheet 25 are arranged in succession so as to intersect in order, and thus constitute a single curtain 20.

Here, the curtain 20 is wound on the roller 15 while being fixed to the frame 11 as shown in FIGS. 3 and 4 and unfolded in a U-shape to unfold in a double layer. That is, when the light-transmitting sheet 21 and the power generating sheet 25 arranged on the inside and the outside are shifted from each other, the entire window is blocked as shown in FIG. 5 to block the field of view.

Conversely, when the light-transmitting sheet 21 and the power generation sheet 25 are in a state in which they match each other, as shown in FIG. 6, the light-transmitting sheet 21 can transmit light to secure a field of view. In any case, light is irradiated onto the power generation sheet 25 to simultaneously unfold the curtain 20 and generate power.

At this time, the curtain 20, the light transmitting sheet 21 and the power generating sheet 25, as shown in Figure 7, the reflective sheet 26 is further attached to reflect light on one portion of the inner surface facing each other. That is, the light that has passed through the outer transmissive sheet 21 is refracted and scattered by the reflective sheet 26 and is re-incident to the power generation sheet 25 to improve overall power generation efficiency.

Here, the reflective sheet 26 is illustrated as being attached to both the light-transmitting sheet 21 and the power generating sheet 25, but may be attached to either the light-transmitting sheet 21 or the power-generating sheet 25 only.

The control plate 30 is a rod interposed between the double plies of the curtain 20 as shown in FIGS. 1 and 2, and imparts a load that induces the straight unfolding of the curtain 20. The control plate 30 has a predetermined thickness as shown in FIGS. 3 and 4 and protrudes to the same or greater length than the width of the curtain 20, and has a width W greater than the spacing between double plies according to the unwinding of the curtain 20. Is formed.

That is, the throttle 30 is rolled according to the unwinding of the curtain 20 and varies the unfolding angle of the curtain 20 according to the illumination of sunlight. Here, the control plate 30 is preferably formed to a size that varies the unfolding angle of the curtain 20 within a range of ± 15 ° according to a position where the width W coincides with or perpendicular to the curtain 20.

For example, in the process of unfolding the curtain 20, when the throttle 30 is rolled in a posture with the width W as shown in FIG. 3, the unfolding angle of the curtain 20 becomes 0 ° or -15 °, and the throttle 30 4) when the width (W) is rolled in a posture facing horizontally as shown in FIG. 4, the unfolding angle of the curtain 20 becomes + 15 °.

Therefore, the user unfolds the curtain 20 in a desired awning state, and then adjusts the angle of the curtain 20 by varying the posture of the control plate 30 through fine adjustment. It is possible to maximize the amount of power generation by adjusting the angle of the curtain 20 to an angle suitable for a time zone or a season.

At this time, the control plate 30 is preferably attached to the reflective piece 31 that reflects light on one or both sides as shown in FIG. 8A. That is, as shown in FIG. 9, the light passing through the outer transmissive sheet 21 is refracted and scattered by the reflective piece 31, and is re-incident to the power generating sheet 25, thereby improving the overall power generation efficiency.

In addition, the control plate 30 is preferably attached to the friction pad 35 to suppress the sliding on one side or both side width (W) as shown in Figure 8b. The friction pad 35 is made of a soft rubber material to increase the frictional force with the curtain 20. Therefore, a smooth rolling motion ensures accuracy according to the adjustment.

In addition, the control plate 30, as shown in Figure 8c, it is preferable that the guide piece 36 is further attached to wrap around both sides of the curtain 20 to prevent departure. The guide piece 36 can prevent the deviation in the rolling process due to the contact deviation with the curtain 20 to ensure safety in use.

On the other hand, the blind 100 according to the present invention is provided on each of the curtain 20 and the control plate 30 as shown in FIG. 10, and further includes a guiding means 40 for automatically controlling the unfolding angle at the point where the curtain 20 is completely released. can do.

The guide means 40 is adsorbed according to the magnetic force of the electromagnet 41 on the inner surface of the power generation sheet 25 facing each other according to the amount of power generation, and the width (W) of the control plate 30. It consists of a reacting magnetic body (45).

That is, even though an initial posture is set because the control plate 30 rolls according to the unfolding of the curtain 20, the width W of the control plate 30 is as shown in FIG. 3 in a state where the curtain 20 is fully extended according to the user's operation. There is a possibility to have a vertical position.

Therefore, the user has to rewind the curtain 20 in order to improve the power generation efficiency, so that the width W of the control plate 30 must be changed to a posture facing horizontally. However, by winding the curtain 20, another problem occurs that does not cover the lower portion of the window.

That is, when the curtain 20 is fully unfolded, the electromagnet 41 and the magnetic body 45 are adsorbed to each other even when the width W of the control plate 30 has a vertical posture, and the posture has the best angle of solar efficiency Is switched to. Here, the electromagnet 41 outputs a magnetic force proportional to the amount of power generated, and is separated from the adsorbed magnetic body 45 as the amount of power generated offsets during the process of winding the curtain 20.

At this time, the electromagnet 41 is shown as attached only to the fully extended portion of the curtain 20, but may be arranged as a whole at predetermined intervals in some cases. In this case, even if the user does not adjust the unfolding angle of the curtain 20 individually, the electromagnet 41 outputs magnetic force according to the amount of power generation, thereby changing the posture of the control plate 30.

In this way, the present invention is a light-transmitting sheet and a roll-type curtain composed of a photovoltaic power generation sheet in a double layer, so that the user can control the sunshade and develop power. In addition, it is possible to maximize the power generation efficiency while minimizing the production cost by inducing the angle of the power generation sheet to be varied according to the illumination of the sun with only a control plate that induces straight unfolding of the curtain by adding weight. In addition, a sufficient amount of power generation can be expected to store energy consumed by other devices by refracting the light transmitted through the curtain by the reflective sheet and the reflective piece to the inner surface of the power generation sheet. In addition, the friction pad smoothly induces the rolling of the throttle as the curtain unwinds and winds up to improve the accuracy of operation, and the guide side can be secured in use by preventing deviation without being affected by contact deviation with the curtain. The guide means can adjust the rolling position of the control panel to adjust the opening angle of the curtain at all times, regardless of the height of the window or the user's arbitrary adjustment.

The present invention can be used for roll blinds capable of shading control and photovoltaic power generation by using a roll-shaped curtain comprising a light-transmitting light-transmitting sheet and a photovoltaic power-generating sheet.
