8results about How to "Save weight" patented technology

This invention relates to the field of battery technology, and more particularly to a battery device. The battery device includes a battery pack comprising a plurality of batteries arranged along a first direction. The terminal assemblies of the batteries are located on surfaces other than the top surface of the batteries, and an insulating film is disposed on the top of the battery pack. Through this design, the present invention utilizes the insulating film to prevent contact between the battery pack and the cover or other structures located above the battery pack when the batteries expand and deform, or when the cover deforms due to vibration of the battery device, thus reducing safety hazards. Furthermore, since the insulating film is easier to form than the insulating plate, especially as the size increases (the forming difficulty of the insulating plate increases), and the insulating film is thinner, it can save top space and weight of the battery device. In addition, the insulating film is a flexible material and is easier to compress, further reducing the space occupied.

This utility model relates to the field of dust control technology, and in particular to a dust control facility for construction sites, including a handcart. The handcart is equipped with a dust control mechanism for dust control. The dust control mechanism includes: a spray assembly, including a frame fixed on the handcart, a circular plate fixed to the front end of the frame, an arc-shaped tube fixed to the front end of the circular plate via a fixing bracket, a plurality of circumferentially distributed atomizing nozzles installed at the front end of the arc-shaped tube, a cylinder seat fixed to the front end of the circular plate, and a fan blade installed inside the front end of the cylinder seat; a water supply assembly, mounted on the frame and used for water supply; and a drive device, mounted on the frame and used for power supply. Through the circumferential layout of the arc-shaped tube and the circumferential distribution of the atomizing nozzles, the water mist spray range expands in a ring shape. Combined with the airflow propulsion effect of the fan blades, the dust control facility significantly improves the capture efficiency and settling speed of airborne dust.
