Description

Technical Field

[0001] The utility model relates to the technical field of buildings, in particular to an automatically controlled high-rise building sunshade. Background Art

[0002] Building sunshades are generally used in hot seasons to prevent the sun from shining on buildings and causing the temperature inside the building to rise. Since high-rise buildings are not blocked by objects, they are exposed to the sun for a longer time and are more dependent on sunshades. The existing patent (application number 202023205398.2) provides a high-rise building balcony sunshade that can adjust the shading area according to needs, but the patent still has at least the following shortcomings when used:

[0003] 1. The utility model needs to manually adjust the sun visor when in use. At the same time, the sun's irradiation angle is different at different times. The sun visor cannot be controlled at all times during manual adjustment. Therefore, we need an automatically controlled sun visor;

[0004] 2. When the sun is irradiated, the temperature rises due to heat radiation. When the sunshade in the utility model is exposed to the sun, its own temperature rises, and heat transfer and heat radiation will be carried out in the building, which will still cause the indoor temperature to rise. Therefore, we need a sunshade that can avoid heat radiation;

[0005] 3. Since there is strong wind outside high-rise buildings, in order to avoid the sunshades being damaged by strong winds, the sunshades of high-rise buildings are generally installed indoors. The sunshades will take up a lot of space when used indoors, so we need a space-saving sunshade. Utility Model Content

[0006] The main purpose of the utility model is to provide an automatically controlled high-rise building sunshade, which can effectively solve the problems in the background technology.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0008] An automatically controlled high-rise building sunshade comprises a shell and a sunshade, wherein a mounting seat is arranged on the top of the shell, a motor for driving a rotating shaft is arranged on the side of the shell, a telescopic rod is arranged in front of the shell, a light sensor with an adjustable angle is arranged at the end of the telescopic rod, a rotating shaft is arranged inside the shell, a sunshade is rolled up on the rotating shaft, and a drop rod is arranged at the bottom of the sunshade.

[0009] Further: one side of the shading plate is provided with a reflective coating for reflecting light radiation.

[0010] Further: the reflective coating is a metal coating or a reflective film.

[0011] Further: the side of the shading plate provided with the reflective coating faces the side of the housing on which the light sensor is installed.

[0012] Further: the motor is installed on a radial side of the rotating shaft outside the shell, and the motor is transmission-connected to the rotating shaft.

[0013] Further: a rotating base is provided at the end of the telescopic rod, and the light sensor is installed on the rotating base.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. The sun visor in this application is controlled by a controller plus a sensor. It can automatically unfold to block the sunlight when the light is strong, and automatically close the sun visor when the light is insufficient, providing lighting for the room without the need for manual adjustment at all times.

[0016] 2. An anti-radiation layer is set on the outer layer of the sun visor to prevent sunlight radiation when the sun visor is exposed to the sun, avoid thermal radiation from heating the sun visor, keep the sun visor at a lower temperature at all times, and effectively reduce the indoor temperature.

[0017] 3. Install the sun visor on the roof area and set the sun visor to a retractable structure. When the sun visor is not needed, the sun visor will automatically fold into the installation area on the roof, effectively saving indoor space. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Example

[0026] See also Figure 1-3 The utility model provides a technical solution for automatically controlling the sunshade of a high-rise building:

[0027] An automatically controlled high-rise building sunshade comprises a shell 1 and a sunshade 7, wherein a mounting seat 2 is arranged on the top of the shell 1, a motor 3 for driving a rotating shaft 6 is arranged on the side of the shell 1, a telescopic rod 5 is arranged in front of the shell 1, a light sensor 4 with an adjustable angle is installed at the end of the telescopic rod 5, a rotating shaft 6 is installed inside the shell 1, a sunshade 7 is rolled up on the rotating shaft 6, and a drop rod 8 is arranged at the bottom of the sunshade 7.

[0028] In this embodiment, a light sensor 4 is installed on the shell 1, and the light sensor 4 is installed on the telescopic rod 5 by a rotating base. When in use, the angle of the light sensor 4 is adjusted so that the light sensor 4 can face the sun and can better monitor the light intensity. A fixed value is set for the light sensor 4. When the light intensity detected by the light sensor 4 is greater than the fixed value, the motor 3 starts to rotate clockwise. Since a drop rod 8 is installed under the sunshade 7, the sunshade 7 will drop when the motor 3 rotates; when the light intensity detected by the light sensor 4 is less than the fixed value, the motor 3 can rotate counterclockwise, driving the rotating shaft 6 to roll up the sunshade 7 and retract it into the shell 1. The automatic opening and closing of the sunshade is achieved by installing the light sensor 4, and the sunshade can be automatically deployed when the light is strong without manual adjustment.

[0029] In this embodiment, a reflective coating 9 is provided on one side of the sunshade 7. The reflective coating 9 is provided on the surface of the sunshade 7 to reflect light. The metal reflective film can reflect most of the heat of sunlight, especially the light in the visible and near-infrared regions. The metal reflective film with good performance can reflect up to 85% or even more of the heat of sunlight, thereby reducing the temperature rise inside the building. The reflective coating 9 is provided on the surface of the sunshade 7 to solve the problem of secondary radiation heat transfer of the heat-absorbing sunshade, that is, they will not release the heat again after absorbing it, but directly reflect it, thereby achieving a better heat insulation effect and effectively preventing the indoor temperature of the high-rise building from being irradiated by light. In this embodiment, the motor 3 adopts the HANPOSE 42HS80 drive integrated stepper motor, which has a simple structure and a holding torque of 0.9 Nm. The light sensor 4 adopts the digital light intensity sensor module driven by the BH1750 of the zave store, and realizes the control of the motor 3 by connecting with the main control board.

[0030] In this embodiment, the shell 1 is installed on the indoor roof by hoisting, the side on which the light sensor 4 is installed is installed toward the window, and the shell 1 is installed as close to the window as possible. The mounting seat 2 arranged on the top of the shell 1 can be fixed by installing expansion screws. Installing the sunshade 7 on the indoor roof not only avoids the risk of damage to the sunshade caused by outdoor wind of high-rise buildings, but also does not occupy indoor use space.

[0031] In summary, the utility model installs a light sensor 4 on the shell 1 to monitor the light intensity, and automatically controls the motor 3 according to the monitored light intensity, so that the sunshade can be automatically deployed when the light is strong without manual adjustment; a reflective coating 9 is provided on one side of the sunshade 7 to reflect sunlight, thereby reducing the temperature rise inside the building, solving the problem of secondary radiation heat transfer of the heat-absorbing sunshade and achieving a better insulation effect; the utility model installs the shell 1 on the indoor roof by hoisting, which not only avoids the risk of damage to the sunshade by the outdoor wind of the high-rise building, but also does not occupy the indoor usable space.

[0032] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
