This invention discloses an optical imaging lens, comprising an outer cover, a lens barrel, and a plurality of lenses disposed within the lens barrel. The front end of the lens barrel includes an object-side opening, and the rear end includes an image-side opening. The inner diameter of the object-side opening is smaller than the inner diameter of the image-side opening. The outer cover is conical and disposed on the outer surface of the front end of the lens barrel. The outer cover includes an object-side opening and an image-side opening, the maximum outer diameter of which is smaller than the maximum outer diameter of the image-side opening. The length of the outer cover along the optical axis is greater than 40% of the length of the lens barrel along the optical axis.

This utility model discloses a bending-resistant sound barrier column, including a base, a bending-resistant structure installed at the top of the base, and a protective structure installed at the top of the bending-resistant structure. The bending-resistant structure includes a pre-embedded steel plate set at the top of the base, with screw holes on the surface of the pre-embedded steel plate. Screws are installed inside the screw holes, with a main nut installed at the top of the screw and a secondary nut installed at the top of the main nut. A straight side plate is installed at the top of the pre-embedded steel plate, and a column is installed on one side of the straight side plate. Longitudinal reinforcing plates are installed on both sides inside the column. This utility model allows for precise adjustment of the preload by tightening the main nut and secondary nut using a torque method. The contact surfaces of the main nut and secondary nut generate additional frictional resistance, effectively resisting loosening between the internal and external threads. The straight side plate and the arc-shaped side plate are welded to both sides of the column to form a streamlined surface, reducing wind resistance or fluid resistance.

This application discloses an explosion-proof and noise-reducing valve shell structure for nuclear power plants, belonging to the field of valve technology. It mainly includes: a valve shell with water pipes connected to both ends, an installation pipe connected to the upper end of the valve shell, an explosion-proof assembly mounted on the valve shell, the explosion-proof assembly including two explosion-proof covers fitted onto the valve shell, each explosion-proof cover having a limiting hole at both ends, a main reinforcement assembly mounted on the explosion-proof covers, the main reinforcement assembly including reinforcing semi-rings mounted at both ends of the explosion-proof covers, the lower ends of the reinforcing semi-rings embedded in the limiting holes, and an auxiliary reinforcement assembly mounted on the installation pipe. This explosion-proof and noise-reducing valve shell structure for nuclear power plants, by using the two explosion-proof covers of the explosion-proof assembly to wrap around the outer wall of the valve shell and cover the lower part of the water pipes, can resist external impacts, reduce the occurrence of local deformation or cracking of the valve shell, and improve the explosion-proof threshold of the valve.
