Description

Photovoltaic sunshade component for building

Technical Field

The utility model belongs to the technical field of photovoltaic equipment, and in particular relates to a photovoltaic sunshade component for buildings.

Background technique

Building shading is a necessary measure to avoid direct sunlight into the interior, prevent the building's outer envelope from being overheated by the sun, thereby preventing local overheating and glare, and protecting various indoor items. Reasonable design of building shading can improve indoor comfort in summer and reduce building energy consumption. At present, many buildings have responded to the national call to develop and install photovoltaic sunshades, which not only provide shading for the building, but also effectively use light energy for energy conversion and utilization.

Most of the existing photovoltaic sunshades on the market have the following problems when in use:

1. The angle of the photovoltaic sunshade cannot be adjusted during use. When the light angle changes, the sunshade cannot always maximize the use of light;

2. The photovoltaic sunshade is installed in a relatively fixed manner and cannot be folded, so the area of light entering the room cannot be adjusted at different time periods. For example, when the sunlight is not so glaring in the morning and evening, the photovoltaic sunshade can be folded to allow more sunlight to enter the room and increase indoor lighting. When the sunlight is strong at noon, the photovoltaic sunshade is opened to block the glaring sunlight. Therefore, it is not flexible to use and has poor practicality.

To this end, a photovoltaic sunshade component for building is proposed.

In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

Example 1

Referring to Figures 1 to 5, this embodiment provides a photovoltaic sunshade component for construction, including: a bracket group fixedly connected to the eaves of a building 1, the bracket group including a mounting base plate 2 fixedly connected to the eaves, a plurality of supporting oblique bars 3 are rotatably connected to the mounting base plate 2, the ends of the supporting oblique bars 3 away from the mounting base plate 2 are rotatably connected to the supporting cross bars 4, support columns 5 are fixedly connected to both ends of the supporting cross bars 4, and the other ends of the supporting columns 5 are fixedly connected to the outer wall of the building 1, a sliding groove 6 is provided in the center of the supporting oblique bars 3, a plurality of sliding blocks 7 are slidably connected in the sliding groove 6, a scissor assembly is hinged on the sliding block 7, photovoltaic panels 8 are fixedly connected to both sides of the scissor assembly, and the end of the scissor assembly close to the eaves is transmission-connected to a telescopic assembly; a plurality of supporting oblique bars 3 are fixedly connected to the top ends with rotating gears 9, the rotating gears 9 are fixedly connected to the telescopic assembly at one end away from the supporting oblique bars 3, and the rotating gears 9 are transmission-connected to the rotating assembly.

The bracket group forms a sunshade frame through the support inclined strip 3, the support horizontal strip 4, the support column 5 and the eaves, providing a basis for the installation of the photovoltaic panel 8. The support inclined strip 3 is provided with a sliding groove 6, and the sliding block slides in the sliding groove 6. The scissor assembly can be guided to extend and retract in the direction of the support inclined strip 3 through the sliding block. The photovoltaic panel 8 is fixed to both sides of the scissor assembly and can be extended and retracted with the extension of the scissor assembly, so that the user can adjust the size of the shading area of the photovoltaic panel 8, which is more practical; the rotating assembly can drive the rotating gear 9 to rotate slightly, thereby driving the support inclined strip 3 and the telescopic assembly connected thereto to rotate slightly together, and the rotation of the support rack 18 can rotate the scissor assembly located thereon, so that the photovoltaic panel 8 fixed to the scissor assembly is tilted, and then the photovoltaic panel 8 can be rotated according to the angle of the sun rising in the east and setting in the west, so that the photovoltaic panel 8 can receive more light. The photovoltaic sunshade of the present application can be extended and retracted to change the shading area. The user can choose the area of light entering the room according to the weather of the day and the light intensity at different times, and can also rotate the angle with the sun rising in the east and setting in the west, so as to obtain more light. The photovoltaic panel 8 is electrically connected to a corresponding inverter and a battery, etc., and the electrical energy converted from light energy is stored in the battery. Meanwhile, the electrical energy in the battery can be used as the power of the rotating assembly and the telescopic assembly, thereby saving energy and reducing emissions.

A further optimized solution is that the scissors-type assembly includes a forward frame bar 10 and a reverse frame bar 11 which are in the shape of scissors and hinged to each other, and mounting bars 12 are vertically fixed to both sides of the forward frame bar 10, and the photovoltaic panel 8 is fixed to the mounting bars 12. The hinge point between the reverse frame bar 11 and the bottom end of the forward frame bar 10 is also hinged to the slider 7, and the end of the reverse frame bar 11 close to the eaves is fixed with a first connecting rod 13, and the end of the first connecting rod 13 away from the reverse frame bar 11 is transmission connected to the telescopic assembly.

The forward frame 10 faces the sun, so installing the photovoltaic panel 8 on the forward frame 10 is more conducive to the photovoltaic panel 8 absorbing light energy. The forward frame 10 and the reverse frame 11 form a scissors structure. For details, please refer to the scissors structure of the scissors lift. The photovoltaic panel 8 fixed thereon can be expanded in plane or contracted vertically. The hinge point between the reverse frame 11 and the bottom end of the forward frame 10 is also hinged to the slider 7. The slider 7 can guide the extension and retraction direction of the scissors assembly to avoid shaking; the first connecting rod 13 is fixed to the reverse frame 11 at a certain angle.

To further optimize the solution, several telescopic components are arranged corresponding to the scissor-type components. The telescopic component includes a telescopic groove 14 fixedly connected to the roof of the building 1, a telescopic block 15 is slidably connected in the telescopic groove 14, the top of the telescopic block 15 extends out of the telescopic groove 14 and is hinged with a second connecting rod 16, and the end of the second connecting rod 16 away from the telescopic block 15 is hinged to the first connecting rod 13, the telescopic groove 14 is cylindrical in outer surface, the telescopic groove 14 is coaxial with the supporting cross bar 4, and a corresponding rotating groove 22 is provided on the outer rotation sleeve of the telescopic groove 14. The bottom surface of the rotating groove 22 is fixedly connected to the top surface of the building 1 through the vertical rod 23, and the first telescopic rod 17 is fixedly connected to one end of the rotating groove 22. The movable end of the first telescopic rod 17 passes through the rotating groove 22 and the side wall of the telescopic groove 14 and is rotatably connected to the side wall of the telescopic block 15; the end of the telescopic groove 14 away from the first telescopic rod 17 is fixedly connected to a connecting column 24, and the connecting column 24 passes through the rotating groove 22 and is fixedly connected to the rotating gear 9.

The first telescopic rod 17 pushes the telescopic block 15, causing the telescopic block 15 to slide in the telescopic groove 14, thereby pushing the second connecting rod 16 and the end hinged to the telescopic block 15 forward or backward. The forward and backward movement of the second connecting rod 16 drives the first connecting rod 13 to rotate around the hinge point of the slider 7, thereby causing the scissors assembly to extend or retract; the telescopic groove 14 is cylindrical, and a rotating groove 22 is arranged on its outer surface. When the rotating gear 9 rotates, it can drive the telescopic groove 14 to rotate in the rotating groove 22, so that the telescopic groove 14 and its internal telescopic block 15 and the second connecting rod 16 rotate synchronously with the supporting oblique bar 3.

A further optimized solution is that the rotating assembly includes a rack 18, which is meshedly connected to a plurality of rotating gears 9, and a rack groove 19 is slidably connected to the bottom end of the rack 18, and the bottom of the rack groove 19 is fixedly connected to the top of the building 1; one end of the rack 18 is fixedly connected to a second telescopic rod 20, and the second telescopic rod 20 is fixedly connected to the top of the building 1.

The second telescopic rod 20 can drive the rack 18 to slide left and right in the rack groove 19, so that the rotating gear 9 meshing with the rack 18 rotates, and then the supporting inclined bar 3 and the telescopic assembly rotate, so that the photovoltaic panel 8 rotates around the central axis of the supporting inclined bar 3.

According to a further optimization scheme, the top of the photovoltaic panel 8 is longer than the top of the forward frame bar 10 , and the bottom is shorter than the bottom of the forward frame bar 10 .

In order to avoid interference between the photovoltaic panels 8 and the scissors assembly during the extension and retraction process, the bottom end is made shorter than the bottom end of the forward frame bar 10. When unfolding, the bottom end of the photovoltaic panel 8 can be avoided from interfering with the scissors assembly. The top end of the photovoltaic panel 8 is longer than the top end of the forward frame bar 10, which can make up for the missing part of the bottom end and expand the area of the photovoltaic panel 8.

According to a further optimized solution, the first telescopic rod 17 is a multi-stage telescopic rod, and the photovoltaic panel 8 is a flexible photovoltaic panel 8 .

When the multi-stage telescopic rod is retracted to a constant length, the travel is longer, and the flexible photovoltaic panel 8 is light and has a certain degree of flexibility, making the telescopic rotation more convenient.

To further optimize the solution, rotating columns 21 are fixedly connected at both ends of the supporting oblique bars 3, and the rotating columns 21 are rotatably connected to the mounting base plate 2 and the supporting horizontal bars 4. The top of the rotating column 21 at the top of the supporting oblique bars 3 passes through the mounting base plate 2 and is fixedly connected to the rotating gear 9.

According to a further optimized solution, the first telescopic rod 17 and the second telescopic rod 20 are both electrically connected to a control component.

The control component controls the start and stop of the first telescopic rod 17 and the second telescopic rod 20, thereby controlling the extension and rotation of the photovoltaic sunshade component. The control component can be installed at the bottom of the building 1 for easy use.

As shown in Figure 6, the difference between this embodiment and embodiment 1 is that this embodiment is applicable to multi-story buildings, such as residential buildings. During installation, a fixing plate 25 can be fixed above the window that needs shading, and the mounting base plate 2, rack groove 19 and other structures installed on the roof in embodiment 1 are installed on the fixing plate 25. In addition, the support column 5 needs to be longer than that in embodiment 1 so that the support column 5 can be fixedly installed on the outer wall of the building.
