This utility model discloses a sealed food storage container, including a container body, a lid that fits with the container body, and a flexible sealing ring. The lid is a downward-opening cover structure. An annular groove with the opening facing downwards is provided around the outer edge of the container body's opening. The upper part of the sealing ring is embedded in the annular groove, while the lower part of the sealing ring protrudes outside the annular groove, sealing with the inner wall of the lid when the lid is placed on the container body's opening. This sealed food storage container achieves a seal while preventing the sealing ring from contacting the food inside the container, thus effectively preventing food stains from remaining on the sealing ring and preventing contamination of the food inside the container. Therefore, frequent disassembly and cleaning of the sealing ring is unnecessary, reducing the user's maintenance burden. Furthermore, since the edge of the lid and the sealing ring are not located within the internal space of the container body, the container body can achieve a larger effective volume with the same external dimensions, fully accommodating food and improving its internal space utilization.

This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and more particularly to an inspection UAV for power distribution network maintenance. The UAV includes a UAV body with symmetrically fixed arms on both sides. A propeller is rotatably mounted on the top of each arm. A camera is mounted on the front end of the UAV body. A support mechanism is also present at the bottom of the UAV body, providing support during landing and significantly improving operational stability in complex environments, protecting internal precision sensors and the camera from mechanical damage. A protective mechanism is also present at the front end of the UAV body, protecting the camera with a protective cover and effectively blocking the direct impact of the propeller's downwash airflow on the camera during landing. This utility model significantly improves the efficiency and safety of power grid operation and maintenance through the cooperation of the support and protective mechanisms.

This utility model relates to the field of shielding film technology and discloses a rewinding device for shielding film production, including a base, with a motor fixedly connected to one side of the outer wall of the base. In this utility model, the airflow generated by the air pump enters the inner cavity of the guide roller through a connecting pipe and is discharged through an exhaust hole to form a stable air film. This air film provides flexible support, offering uniform lifting force to the shielding film to maintain a stable transmission height and path. It also reduces the direct contact area between the shielding film and the guide roller, fundamentally reducing the amount of static electricity generated by solid friction, significantly reducing the probability of dust and impurity adsorption, and effectively preventing stains or impurity indentations on the product surface. Simultaneously, when the motor drives the lead screw to rotate, the rotational motion can be converted into linear motion through a slider, enabling flexible adjustment of the axial position of the guide roller and ensuring that the air film always acts on the central area of ​​the shielding film, guaranteeing support stability.

The utility model provides a kind of solar unmanned aerial vehicle base station, scraper is through the upper end of water storage box, scraper is slid on the upper end of water storage box by sliding block, the lower end of scraper and the upper end of bearing two are perpendicular direction sliding friction, blade is 360 ° rotation on the upper end of filter plate by bearing two, boss is inverted conical, the lower end of boss and the upper end of filter plate are slidingly attached, blade, boss and bearing two are equipped with multiple groups, evenly arranged on the upper end of filter plate, when water storage box is inclined swing in perpendicular direction, sliding block is slid in the sliding slot inside water storage box, sliding block drives scraper to slide on the upper end of water storage box, scraper can clean impurity on the upper end of filter plate when sliding, using the lower end of scraper and the upper end of bearing two are perpendicular direction sliding friction, scraper can assist bearing two rotation, scraper drives blade rotation by bearing two, blade lower end boss can clean filter plate surface impurity, simultaneously can reduce the blockage of filter plate internal hole by boss.

This utility model relates to the field of sorting technology and discloses an intelligent supply chain logistics automated sorting device, including a conveyor and a conveyor belt installed on the surface of the conveyor. A sorting machine is fixedly installed on one side of the conveyor, and a collection box is fixedly installed at one end of the conveyor. A pushing component is installed on one side of the collection box, and an adjusting seat is fixedly installed on one side of the collection box. A scraping component is installed on one side of the adjusting seat and contacts the conveyor belt. A cleaning component is installed on one side of the collection box, and a collection box is slidably connected to one side of the collection box. The pushing component can push dirt and other debris out of the collection box and into the collection box for collection. The cleaning component can clean the surface of the pushing component, preventing dirt and other debris from adhering to the surface of the conveyor belt. Therefore, through the dual action of actively cleaning the surface of the conveyor belt and passively intercepting falling debris, dirt and other debris can be prevented from adhering to the surface of the conveyor belt.
