Technical Field

The invention belongs to the field of buildings, and particularly relates to a dimming and cooling roof mechanism for a building.

Background

With the development of cities, the population density is higher and higher, so that the land resources are more and more precious, and high-rise buildings can only be continuously built to increase the usable area.

However, as the height of the building is higher and higher, the distance from the building to the sun is closer, so that the illumination intensity of the top floor is higher, especially in hot summer, sunlight can directly enter the room through the skylight, so that not only can intense discomfort be brought to residents, but also indoor building materials, furniture and the like can be damaged, in addition, the indoor temperature can be rapidly increased due to continuous irradiation of the sunlight, the temperature can only be reduced by using an air conditioner and the like, and the energy consumption is higher.

Therefore, we propose a dimming and cooling roof mechanism for building to solve the above problems.

Disclosure of Invention

The invention aims to provide an energy-saving and environment-friendly dimming and cooling roof mechanism for a building, aiming at the problems of strong illumination of a top-level building and excessive temperature in the daytime.

In order to achieve the purpose, the invention adopts the following technical scheme: a light-adjusting and temperature-reducing roof mechanism for buildings comprises a transparent and disc-shaped shell, clear water is filled in the shell, the upper side wall of the shell consists of a transparent circular plate and an annular plate which are arranged at the center of the shell, the annular plate is provided with a light transmitting area and a light shading area in a staggered manner, a fixed shaft is fixedly connected in the shell along the axis direction, an external thread is arranged on one end of the fixed shaft, the external thread is sleeved with a rotating plate in a threaded manner, the rotating plate is fixedly connected with a plurality of light shading sheets in the circumferential direction, each light shading sheet corresponds to each light transmission area one by one, the upper end of the rotating plate is provided with a light sensing floating ring, the light sensing floating ring expands when being illuminated, the rotating plate is driven to spirally rise along the external thread under the buoyancy action of the light sensation floating ring so that each shading sheet rotates to the position right below each light-transmitting area, the upper end of the fixed shaft extends out of the shell and is provided with a deformation mechanism for offsetting the volume change of the light sensation floating ring.

The invention has the following beneficial effects: through the arrangement of the water injection hollow shell, the water with larger specific heat capacity can be utilized to absorb the illumination heat in the daytime, so that the situation of too fast temperature rise can not be caused while enough illumination is obtained indoors, and at night, the water body absorbing heat gradually releases heat and can also play the effects of heating and heat preservation indoors;

through setting up the light sense floating collar, when receiving illumination, the light sense floating collar inflation produces great buoyancy to drive the rotor plate and rise, under the mating reaction in anti-dazzling screen and anti-dazzling area, can make the incident light of the upper end of casing sheltered from.

In foretell for building adjust luminance cooling roof mechanism, the light sense floating collar is made by transparent, elasticity silica gel material, the airtight setting of light sense floating collar, the light sense floating collar intussuseption is filled with silver bromide powder and copper oxide powder, utilizes the silver bromide to see the light and decomposes and produce gaseous characteristic for light sense floating collar volume grow, buoyancy increases to can drive the rotor plate and upwards float.

In foretell for building adjust luminance cooling roof mechanism, deformation mechanism is including connecting the elasticity bellows in the fixed axle upper end, be equipped with the opening of intercommunication elasticity bellows and casing inside on the fixed axle, can offset the influence that the volume change of light sense floating collar brought for the internal and external pressure balance of casing.

In foretell for building adjust luminance cooling roof mechanism, the upper end fixedly connected with threaded rod of elasticity bellows, threaded rod external screw thread connection has the swivel sleeve, the swivel sleeve rotates the upper surface of connection at the casing, many clean strips of the outer fixedly connected with of swivel sleeve, the lower extreme of clean strip and the upper surface laminating of casing can utilize elasticity bellows drive threaded rod rebound for the swivel sleeve drives clean strip and takes place to rotate, thereby cleans the upper surface of casing, reduces piling up of dust, thereby improves the transmittance.
