Embodiment 1

[0035] refer to Figure 4 , the exterior wall 2 includes several layers of walls 201 that are horizontally divided;

[0036] The walls 201 of several layers are filled with deformable layers 202 for flexible adaptation to the external environment, and proper deformation and restoration according to the external temperature. A plurality of support columns 203 are vertically arranged inside the wall 201 of each layer for stabilizing the wall 201 and enhancing its stability. The deformable layer 202 is made of materials whose volume will change due to the influence of temperature, such as wool, asbestos fiber, diatomaceous earth and other materials.

[0037] The lower surface of the outer wall 2 is provided with a cavity, which is used to accommodate the inner wall 1, and the height of the cavity is greater than the height of the inner wall 1, so as to avoid thermal expansion and contraction, which cannot work situation. The height of the linear driver one 3 is smaller than th...

Embodiment 2

[0040]The sunlight collecting end comprises a solar altitude positioning sensor, a solar azimuth positioning sensor, an illumination sensor and a time zone sensor, and the solar altitude positioning sensor, a solar azimuth positioning sensor, an illumination sensor and a time zone sensor are electrically connected to the input end of the control terminal , to obtain information about sun angle, altitude, light intensity and time zone position. The sun altitude positioning sensor indicates the angle of the sun through continuous and discrete signal outputs. The light sensor uses an advanced photoelectric conversion module to convert the light intensity value into a voltage value, and then convert the voltage value into 0~2V or 4~20mA through the conditioning circuit.

[0041] The control terminal includes a calculation unit and a comparison unit inside, the calculation unit calculates the sun altitude angle according to the received sensor information, and sends the calculation...

Abstract

The invention discloses a passive sunshade wall based on a solar elevation angle, and relates to the technical field of wall sunshade. A structure in which an inner wall and an outer wall are matched is arranged, the height of the outer wall is adjusted by calculating the solar elevation angle, sunlight is prevented from directly entering a courtyard wall, and a movable sunshade plate is arranged at the top of the outer wall, so that purpose of sunshading is further achieved in a matched mode; a multi-layer structure is arranged on the inner wall, the fireproof and damp-proof functions are achieved, a frame type structure is adopted for the outer wall, the firmness and stability of the movable wall are enhanced, a deformation layer is arranged, the movable wall can flexibly adapt to irradiation of different sunshine, and plasticity and adaptability are high; According to the passive sunshade wall based on the solar elevation angle, the structure of the wall is changed according to the collected and calculated solar elevation angle, sunlight is blocked outside a courtyard wall, and the technical effect of passive sunshade is achieved.

Description

technical field [0001] The invention relates to the technical field of wall sunshade, in particular to a passive sunshade wall based on the sun elevation angle. Background technique [0002] In people's rich leisure life, enjoying the cool outdoors has always been a way that people are willing to adopt. This method can greatly reduce the energy loss caused by electric cooling, but outdoor cooling also has problems such as excessive temperature, solar radiation and excess absorption. Technical disadvantages of UV light. [0003] The altitude angle of the sun refers to the angle between the incident direction of sunlight and the ground plane at a certain point on the earth. Professionally speaking, the solar altitude angle refers to the angle between the sun's rays at a certain place and the cut surface of the earth's surface that passes through the place and connects to the center of the earth. When the sun altitude angle is 90°, the solar radiation intensity is the largest...
