Interior sunshade thermal insulation system
The internal shading and thermal insulation system can improve the ecological environment of greenhouses in multiple ways. During summer, shading curtains reflect some sunlight, allowing diffused light to enter the greenhouse and evenly illuminate plants, protecting crops from intense light burns while also lowering the greenhouse temperature. By choosing different curtains, various shading rates can be achieved to meet the different sunlight requirements of various crops. In winter nights, the internal shading and thermal insulation system effectively prevents infrared rays from escaping, reducing ground radiation heat loss and minimizing heating energy consumption, significantly lowering the operation costs of the greenhouse. The shading curtains can maintain indoor humidity control and appropriate thermal levels, preserving the optimal growing environment for plants.

Working Principle
Press the control box's start switch button to activate the motor. The motor drives the drive shaft through a transmission mechanism, which in turn moves the drive rod parallel to the curtain line via connecting components. The drive rod slowly unfolds one end of the curtain until it fully extends, at which point it triggers the stroke limit switch, stopping the motor and ending the journey. The control box is equipped with manual control. To stop mid-operation, press the stop button to halt the operation.
Basic System Composition
1) Control Box and Motor - This box is equipped with two sets of contact devices for unfolding and folding the screen, allowing manual start and stop. It can also achieve automatic parking through a stroke switch. It is capable of accepting computer control. The motor comes with built-in working limit switches and reliable operation. 2) Rack and Pinion - Utilizes imported Dutch rack and pinion, ensuring reliable quality and smooth operation. 3) Transmission - The transmission section consists of an imported Dutch reduction motor and its accessories, delivering power through the reduction motor and the connected drive shaft.
The drive shaft is made of φ42×3.5 seamless steel tube, connected to the motor in the middle, and the rest is evenly connected to the rack subassembly/rack base, converting circular motion into smooth linear motion. The pull/push rod is φ32×2 galvanized steel tube, with each set of racks connected to one row, extending longitudinally to approximately match the length of the greenhouse. The driving rod connected to the pull/push rod is made of aluminum profile, arranged horizontally, pulling the curtain open and closed, making the curtain look flat and beautiful during operation. 4) Curtain Wire: The double-layer curtain wire is made of domestic transparent polyester, with minimal deformation. 5) Curtain: The Shanghai Ruixue aluminum foil sunshade curtain is selected: sealed type, sun shading rate of about 50%, warranty period of 5 years, lifespan of 8 years. 6) Insulation Pocket: Additional insulation pockets are added on both sides of the internal sunshade to improve the thermal insulation performance of the greenhouse and save heating costs. 7) Control Zones: The sunshade control is divided into three control zones: tropical rainforest plant area, succulent and cacti plant area, and seasonal flower plant area.
