In summer, by turning on the water curtain circulation system, a water curtain, that is, a water film, can be formed on the glass water curtain wall 1, and the water flow of the water curtain can take away hot air to cool down the room.

In this implementation, each opening operation part includes a drive motor (not shown), a transmission mechanism (not shown), a pusher 4 and an opening device 5, and the drive motor drives the pusher 4 through the transmission mechanism. One end moves, and one end of the pusher 4 is connected with the middle part of the opening device 5, and the opening device is symmetrically arranged up and down, and the solar glass 31 is installed on the top of the opening device 5, and the lower side glass 32 Installed on the lower part of the opening device 5, the top of the upper part of the opening device 5 is movably connected with the upper end of the corresponding metal frame 2, and the bottom end of the lower part of the opening device 5 is movably connected with the lower end of the corresponding metal frame 2 , the opening device 5 forms a linkage body of the solar cell panel 31 and the lower side glass 32 , and the pusher 4 opens or closes the corresponding solar cell panel 31 and the lower side glass 32 through the opening device 5 .

The worm gear is made of tin bronze material, which can reduce the friction system of the worm gear pair transmission composed of the turbine and the worm, so as to improve the transmission efficiency. The material of the worm is quenched and tempered 45# steel. The worm adopts a trapezoidal tooth profile, and the pitch can be selected as 5mm to ensure that the thread lead angle is a self-locking angle.

In this embodiment, a total of six switch buttons control three rows of windows. When a switch is pressed, a signal is given to the programming controller (hereinafter referred to as PLC). At this time, the PLC will output the signal according to the programmed logic program. The corresponding intermediate relay is switched on and off, and then the driving power of the corresponding driving motor is switched on and off.

Fourth, the system has high security, and the driving motor is a DC motor, so there is no potential safety hazard.

Please continue to refer to Fig. 1 and Fig. 2, preferably, this embodiment also includes a heating collector 7 and an air valve 8, the air inlet of the heating collector 7 communicates with the air insulation space through the air valve 8 , the air outlet of the heating collector 7 communicates with the fresh air pipe. In winter, a part of the sunlight is converted into electrical energy by the solar panel 31, and a part of the sunlight passes through the solar panel 31 to heat the air in the air-tight heat insulation space, by setting the heating collector 7 (such as an air pump) The heated air in the air-insulated space can be sent to the fresh air duct for indoor heating.

The solar panel 31 is connected to the switchboard of the local grid through a grid-connected inverter and some power protection devices, and its power is mixed with grid power to supply power to the load, and excess or insufficient power is regulated through the local grid. The grid-connected photovoltaic system abandons the battery as an energy storage device, and can flexibly configure the photovoltaic system according to the power load, which can range from several kilowatts to hundreds of kilowatts. Due to the seamless connection with the mains, it can be switched to the mains mode in a very short time in bad weather or at night to ensure the normal supply of electricity for users. The power supply system is generally single-phase 220V or three-phase 380V. When the output terminal of the inverter and the public grid are connected in parallel at the low-voltage end, the automatic control device samples the parameters such as voltage, phase, and frequency of the public grid, and adjusts the output of the inverter in real time with the sampled values to ensure that the grid-connected photovoltaic power generation system and Synchronous operation of the public grid.

During the research and development process, the solar panel 31 was initially considered to use a conventional single-glass solar cell, but the following two problems were found after research:

(1) Since the TPT anti-aging film on the back panel is non-transparent and the two sides of the curtain wall system are closed vegetation curtain walls, it will seriously affect the indoor lighting of the case;

(2) After calculation, the structure of the single-glass solar cell cannot meet the strength requirements of the closed cabin switch and wind pressure in terms of strength.

Therefore, preferably, the solar cell panel 31 adopts a double-glass light-transmitting frameless solar cell module, adopts a double-sided glass structure, and is installed by a point method. In this embodiment, the double-glass light-transmitting frameless solar cell module is composed of upper and lower glass, the periphery of the upper and lower glass is sealed by rubber strips, the upper glass is made of solar cell glass, and the lower glass is made of solar cell glass. Glass can adopt general tempered glass. The use of double-glass transparent frameless solar cell modules can be well combined with building exterior walls and ceilings. While satisfying the function of solar power generation, it can also meet the effects of lighting, shading and beautiful decoration inside the building.

The solar panel 31 in this embodiment forms an AC grid-connected system through a grid-connected inverter to provide energy for the power equipment of the water curtain circulation system—the circulating water pump. The whole system is in the "low voltage grid-connected" mode, and does not feed back power to the external public power grid through high voltage and other means. The system requirements: in the case of good weather irradiation conditions, the system can partially meet the power supply of circulating water pumps; in bad weather conditions Part of the electricity can be provided under certain conditions, and the insufficient part is automatically supplemented by the mains supply; the system automatically switches to the mains mode at night. In order to demonstrate energy-saving and environmental protection technologies and reflect the awareness of public participation, the system will also display the working status of the system through data collection and display equipment, including intuitive data such as power generation.

The selection of the glass thickness of the solar panel 31, for the selection of the glass thickness, if the selection is too large, the self-weight of the whole system will be too large, and the deflection under the external load will not meet the requirements; if the selection is too small, the rigidity of the entire structure will not be enough. It is difficult to meet the stress requirements when closing. After multiple rounds of calculation and analysis, it was finally decided to adopt a 6mm+6mm form of 400w (400W with a light transmittance of 25%, and 500W with a light transmittance of 20%) double-glass light-transmitting frameless modules. That is, the thickness of the upper and lower glass blocks in the double-glass light-transmitting frameless solar cell module is 6mm, and when the light transmittance of the upper glass is 25%, the power is 400W, and the light transmittance of the upper glass is 25%. At 20%, the power is 500W. The component size meets tooling requirements. The photovoltaic grid-connected inverter adopts a 6KW photovoltaic solar grid-connected inverter imported from abroad. The AC grid-connected power distribution cabinet is equipped with AC digital ammeters and surge protectors. The power generation system is equipped with data acquisition and communication display equipment, including industrial control machine and LCD display, and data acquisition and display software provided by photovoltaic grid-connected inverter manufacturers. The interface adopts RS485/RS232 interface. The grid-connected power distribution system adopts a single-phase 220V system, uses the reserved line in the A2 cabinet of the underground machine room, and adopts the method of reverse power transmission to the busbar to realize grid-connected connection with the mains.

The main functions of the power generation system composed of the solar panel, grid-connected inverter and some power protection devices are as follows:

(1) Under good sunshine conditions, the system meets part of the power demand of the circulating water pump, the power equipment of the water curtain circulation system;

(2) In poor sunshine conditions or at night, the system can automatically switch to the common mains mode to ensure the power demand of public lighting (automatic switching time is less than 20MS);

(3) The system adopts the maximum power point tracking technology (MPPT) to realize the maximum utilization of solar power generation;

(4) The system has the functions of grid voltage and frequency automatic detection and diagnosis, fault display and alarm, and has the function of manual setting of working voltage and frequency;

(5) The system has the function of anti-islanding effect, and can automatically disconnect the connection with the mains when there is an abnormality at the mains end to ensure safety;

(6) The system has data acquisition and communication display functions, and can display parameters such as current system voltage, operating current, system current power, system current power generation and cumulative power generation, which is convenient for visual observation of system operation;

(7) Except for the AC grid-connected cabinet and display equipment, the rest of the equipment of the system is waterproof outdoor type, with good field installation and maintainability;

(8) The system has a long service life, the solar battery has a service life of more than 25 years, and the service life of other electrical equipment is more than 15 to 20 years.

Finally, the heated air in the air-insulated space is sent to the fresh air duct for indoor heating. That is, by staying in the solar radiation of the glass water curtain wall 1, the heat emitted behind the solar cell panel 31 and the consumption of the glass water curtain wall 1, the air that stays in the airtight compartment between the solar cell panel 31 and the glass water curtain wall 1 is preheated. The preheated air is added to the fresh air through the duct to heat the room.

In summer mode:

Firstly, the opening angle of the window is controlled according to the height of the sun, so that sunlight irradiates the solar panel 31; the higher the sun, the greater the opening angle of the solar panel 31.

Next, the solar panel 31 converts sunlight into electricity and provides it to the electrical equipment of the system (such as a programmable controller for a drive motor, an indoor air conditioner, etc.);

Finally, the water curtain circulation system is turned on, and the hot air in the air-insulated space is taken away by the water flow to cool down the room.
