Description

Technical Field

[0001] The present invention relates to the field of photovoltaic curtain walls, and in particular to a curtain wall photovoltaic grid capable of automatically adjusting light intensity and an installation method thereof. Background Art

[0002] As demand for architectural design increases, a variety of grille designs have gradually developed based on traditional glass curtain walls. However, current grille designs in the industry all connect to rear embedded panels and longitudinal and transverse keels via adapters. Once the installation angle is determined with this anchoring connection method, it cannot be adjusted later. In situations where sunlight is strong or insufficient, the angle of the transverse grille cannot be adjusted to actively improve indoor lighting. Furthermore, when snow accumulates on the grille in winter, it can cause stress on the mounting components of the transverse grille.

[0003] Furthermore, with national policies requiring low-carbon, environmentally friendly, and energy-efficient buildings, the introduction of integrated photovoltaics (IPV) in buildings holds promise for achieving the vision of zero-energy buildings. Currently, IPV in buildings primarily involves photovoltaic solar panels on roofs and photovoltaic curtain walls. While rooftop photovoltaic panels have a high solar energy conversion rate, their limited roof area makes them suitable only for venue-type buildings. Photovoltaic curtain walls, due to their vertical facades, have a narrow angle with the sun, resulting in limited energy conversion. Summary of the Invention

[0004] The purpose of the present invention is to provide a curtain wall photovoltaic grid and an installation method that automatically adjusts the light intensity, so as to solve the technical problems in the prior art of indoor light difference and force concentration caused by the inability to adjust the angle, and poor energy conversion effect caused by the small angle with the sun.

[0005] To achieve the above-mentioned purpose, the present invention provides a curtain wall photovoltaic grille that automatically adjusts the light intensity, including a photovoltaic grille, a fixed splint, a rotating splint and a drive motor. The bottom of the fixed splint is connected to the concrete structure, and the photovoltaic grille is installed on the outside of the rotating splint. The fixed splint and the rotating splint are connected by a splint shaft. A grille gear is provided in the middle position of the splint shaft. A motor shaft is also installed at the lower end of the installation position of the fixed splint and the splint shaft. A motor gear is installed in the middle position of the motor shaft, and a drive motor is installed below the motor gear.

[0006] Furthermore, the bottom of the fixed splint is installed on the concrete structure through chemical anchors arranged on both sides. A stepped table is opened at the upper end of the fixed splint, and a splint shaft slot and a motor shaft slot are opened on the stepped table. The position of the splint shaft slot is lower than that of the motor shaft slot.

[0007] Furthermore, the fixed splints on the concrete structure are arranged in pairs, and the stepped surfaces of the two matching fixed splints are arranged opposite to each other. The splint shaft slots and the motor shaft slots opened on the stepped surfaces are located on the same axis, and an installation gap is left between the fixed splints.

[0008] Furthermore, the rotating splint is a T-shaped support structure, which consists of a fixed plate and an adapter plate. The photovoltaic grid is fixedly connected to the fixed plate of the rotating splint through multiple grid anchors, and a light sensor is reserved in the middle of the photovoltaic grid.

[0009] Furthermore, an opening slot and a shaft mounting hole are provided on the adapter plate of the rotating splint. The opening slot is arranged in the middle position of the shaft mounting hole. The splint shaft is inserted into the shaft mounting hole. The grille gear installed on the splint shaft is embedded in the opening slot.

[0010] Furthermore, the length of the shaft mounting hole is smaller than the length between the shaft grooves of a pair of fixed clamping plates, and the adapter plate of the rotating clamping plate is inserted into the middle gap between the two fixed clamping plates.

[0011] Furthermore, a driving motor is installed at the lower end of the motor shaft, the driving motor drives the motor gear to rotate, and the driving motor is also provided with a signal processor.

[0012] Furthermore, the motor gear and the grille gear are meshed with each other.

[0013] A method for installing a curtain wall photovoltaic grid with automatic light intensity adjustment includes the following steps: S1, measuring and setting out: Based on the design elevation control point positions, a three-dimensional layout robot is used to determine the installation design elevation and control point positions of the fixed clamping plates on the left and right sides of each floor; based on the installation point positions and the dimensional parameters of the fixed clamping plates, the installation edge lines of the rear embedded plates are popped out;

[0014] S2. Single-sided fixed cleat installation: Install the single-sided fixed cleat, adjust its verticality and horizontality, and after ensuring that the installation deviation meets the design requirements, fix the fixed cleat to the concrete structure with chemical anchor bolts, and ensure that the bearing capacity meets the design requirements;

[0015] S3. Install the drive motor 4 and the signal processing integrated circuit: Insert the motor shaft into the motor shaft slot of the fixed clamping plate on one side, and use two upper and lower chemical anchor bolts to fix the drive motor and the signal processing integrated circuit to the concrete structure;

[0016] S4. Installation of the photovoltaic grid and the rotating clamping plate: The photovoltaic grid is fixed with three grid anchor bolts. The grid anchor bolts penetrate the upper and lower sides of the grid. The grid gear is placed in the middle opening. The clamping plate shaft is inserted into the shaft mounting hole and passes through the grid gear. Both ends of the clamping plate shaft extend a certain distance beyond the rear end of the rotating clamping plate to facilitate the installation of the fixed clamping plate.

[0017] S5. Lift the photovoltaic grid and install the fixed splint on the other side: Lift the photovoltaic grid with the rotating splint installed to the same level as the fixed splint on one side, and plug the splint shaft on the rotating splint into the splint shaft slot of the fixed splint on one side. At the same time, mesh the grid gear in the middle of the rotating splint with the motor gear. While ensuring the horizontal installation position, align the splint shaft slot of the fixed splint on the other side with the splint shaft and plug them in. After ensuring the installation position is correct, fix the splint in the same way as S2.

[0018] S6. Matching installation of sensors, remote controls and signal processors: The light sensor collects light intensity and solar angle parameters, and drives the motor according to the correspondence between the optimal solar angle and photovoltaic energy conversion set in the signal processor, driving the photovoltaic grid to rotate and achieve optimal photovoltaic energy collection and conversion.

[0019] Based on the above technical solution, the present invention can achieve the following beneficial effects: The present invention provides a curtain wall photovoltaic grille with automatic light intensity adjustment and installation method, which automatically or manually adjusts the angle between the grille and the curtain wall according to the intensity of sunlight throughout the day. This not only increases the daylighting area through the grille, but also achieves photovoltaic energy conversion through the automatic light intensity adjustment system. Furthermore, the grille angle can be actively adjusted based on user perception to achieve daylighting or sunshade. BRIEF DESCRIPTION OF THE DRAWINGS
