2results about How to "Reduce bending load" patented technology

The application discloses an anti-typhoon wind turbine blade emergency system and method, wherein a heating assembly is arranged at the proximal end of the blade root section of the blade tip section close to the paddle, a positioning device is arranged at the distal end of the blade root section of the blade tip section away from the paddle, after the current wind speed of the environment where the fan is located detected by a wind speed detection device exceeds the design wind speed, the control device determines that a typhoon is coming, switches the working mode of the fan to the anti-typhoon mode, collects the paddle of the fan to the safe position through the variable pitch system, starts the variable pitch brake, and stops the brake to stop the machine, after detecting that the wind speed of the environment where the fan is located exceeds the limit design wind speed, the working mode of the fan is switched to the limit anti-typhoon mode, the standby power supply is started, the heating assembly is controlled to heat the blade tip section, the blade tip positioning signal distance is detected through the positioning device, and after the blade tip positioning signal distance becomes large, it is determined that the blade tip falls off, so that the blade tip section is broken at the specified cross section, and the overall bending load is reduced.

The present invention relates to a reactor (100, 200) for carrying out a chemical reaction, having a reactor vessel (10) and one or more reaction tubes (20), wherein one or more electrical input elements (41) are directed into the reactor vessel (10) for electrically heating the one or more reaction tubes (20), wherein each of the one or more electrical input elements (41) has a rod-shaped segment (43), and the rod-shaped segment (43) passes through the wall (14) of the reactor vessel (10) at a respective wall channel (15). A connecting chamber (60) is provided, into which the rod-shaped segment (43) protrudes, the connecting chamber (60) being arranged outside the reactor vessel (10) and adjacent to the wall (14) of the reactor vessel (10) through which the rod-shaped segment (43) passes in its wall channel (15). A gas feeding device (80-82) is provided, which is configured to load an inert gas into a connecting chamber (60), wherein a wall channel (15) is designed to be permeable, such that at least a portion of the inert gas fed into the connecting chamber (60) flows into the reactor vessel (10), the wall channel (15) having a rod-shaped section (43) therein that is longitudinally movable. The corresponding method is also the subject of this invention.
