Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and particularly relates to an electric induction sunshade photovoltaic ceiling system and its working method. Background Art

[0002] With the intensification of global climate change, the impact of direct sunlight on the internal environment of buildings is becoming increasingly significant. Especially in summer, intense direct sunlight can cause the indoor temperature to rise, thereby increasing the use of equipment such as air conditioners and consuming a large amount of energy. To solve this problem, electric sunshade devices have emerged. They can control the opening and closing of sunshade devices electrically, effectively block direct sunlight, reduce the indoor temperature, and reduce energy consumption. At the same time, the installation technologies of photovoltaic panels and ceiling panels are also constantly developing, and various new materials and design methods are emerging in an endless stream to meet different energy-saving and decorative requirements.

[0003] Existing electric sunshade devices mainly control the opening and closing of sunshade devices manually or remotely. Its main components include sunshade cloth, a reel, a motor, etc. The sunshade cloth is usually made of fire-resistant materials and can effectively block direct sunlight and reduce the indoor temperature. The reel is used to store the sunshade cloth, and the motor is used to drive the reel to rotate to realize the unfolding and retraction of the sunshade cloth.

[0004] There are still some problems with existing electric sunshade devices and ceiling installation technologies:

[0005] (1) In terms of operation, most existing electric sunshade devices require manual or remote control operation, which is inconvenient and does not achieve induction automation.

[0006] (2) In terms of modularity and versatility, the materials and sizes of existing sunshade cloth are fixed and cannot be adjusted according to actual needs.

[0007] (3) In terms of integration, existing sunshade devices and ceiling systems are usually independent and do not achieve an integrated design, which affects the overall aesthetics and coordination.

[0008] (4) In terms of energy utilization, sunshading and solar energy utilization are not fully combined.

[0009] (5) The fire resistance of existing sunshade devices and ceiling systems is insufficient, posing certain safety hazards.

[0010] (6) In terms of maintenance, existing photovoltaic panels do not have a quick-release device, and maintenance and replacement are relatively troublesome.

[0011] The Chinese utility model patent with the authorization announcement number CN218264518U discloses "a large-space gradient flip-type sunshade ceiling", which includes a hoop system one, a hoop system two, a flip unit and a non-flip unit. Circular trays are nested in the middle of the tops of the hoop system one and the hoop system two, and a roof structure ball is locked on the circular tray by high-strength bolts; flip units are arranged below the left and right sides of the hoop system one, and non-flip units are arranged below the front and back sides of the hoop system one. Diagonal corners on the left and right sides of the top of the non-flip unit are provided with the hoop system two. It uses multi-curved perforated aluminum plates as the basic sunshade component units to form an indoor ceiling structure. By simulating and analyzing calculations and respectively determining the flip angles of single plates, it effectively reduces energy consumption, and completely eliminates the direct sunlight through the diffuse reflection method, effectively avoiding the "glare" phenomenon and improving the indoor comfort. However, its structural form is relatively complex, and there are the following deficiencies in actual use: (1) In terms of operation, there is no electric induction element, so automatic control cannot be achieved. (2) In terms of modularization and versatility, this structure is only applicable to large spaces and cannot be used in all building spaces. (3) In terms of integration, its ceiling system is independent and not organically combined with production equipment such as photovoltaic energy-saving panels. (4) In terms of energy utilization, sunshading and solar energy utilization are not fully combined. (5) In terms of cost, since its structure occupies a large top space, it is necessary to increase the height of the building to meet the space requirements, resulting in a higher construction cost.
