1results about How to "Overcome static friction" patented technology

This invention relates to the field of security monitoring technology and discloses an engineering security monitoring device, including a cylindrical shell with an air inlet and an air outlet at both ends. An electrical component is placed inside the air outlet. A heat-conducting plate is located on the side of the electrical component near the center of the cylindrical shell, and the heat-conducting plate is thermally connected to the heat-generating part of the electrical component. A heat-conducting strip is provided on the side of the heat-conducting plate. The device also includes an active heat dissipation mechanism and an air inlet adjustment mechanism. The active heat dissipation mechanism includes a main shaft rotatably connected to the side of the heat-conducting plate and heat dissipation blades located at the end of the main shaft. This invention cleverly overcomes the static friction of the blades through an energy storage and release start-up design, ensuring reliable triggering of forced heat dissipation at high temperatures. It has a simple structure and is easy to install, making it particularly suitable for outdoor scenarios without power supply or where wiring is difficult.
