A wind turbine blade of basalt carbon fibre composite variable density material combination
ActiveCN120667306BImplement a modular designRealizing land transportation problemsThermodynamicsTurbine blade
A wind turbine blade made of basalt carbon fiber composite variable density material combination, including at least one blade unit assembled along the length direction of the blade, the density gradient increases from the blade tip to the blade root through the gradient distribution of material density and / or the gradient distribution of hollow structure, and adjacent blade units are detachably connected through non-threaded connection structure. The modular design of the blade solves the problem of land transportation of oversized blades, and the non-threaded connection (hand disassembly) improves the efficiency of on-site installation and eliminates the risk of thread loosening. Lightweight blade tip reduces starting torque, facilitates handling and assembly, and improves wind speed and power generation efficiency.

An air conditioner mounting bracket installed on a shipping container
ActiveCN224278425Uquick installationprecise positioningLarge containersTank wagonsSteel frameSpot welding
This utility model discloses an air conditioner mounting bracket for installation on a shipping container. The utility model features a modular first mounting component consisting of an indoor air conditioner unit, a first frame, an insulation cover, and a protective cover. A positioning component is also included. During installation, the first mounting component can be moved to the designated position simply by adjusting the position of the positioning tube using the first and second guide parts, enabling rapid installation. Compared to existing technologies that involve on-site welding and assembly, modular installation is faster and more accurate, significantly improving on-site installation efficiency. Furthermore, both the first and second guide parts are detachably installed to the container body via a second support part. Therefore, after the first frame is spot-welded to the container's steel frame, the insert plate can be pulled out from the first clamping block, allowing the first and second guide parts to be disassembled and reused repeatedly, reducing operating costs and facilitating widespread adoption.
