This application relates to the field of photovoltaic module packaging technology, and more particularly to a corner protector for a photovoltaic module frame. The frame has corners, and the corner protector covers these corners. The corner protector includes a lower protector plate, a connecting protector plate, an upper protector plate, and an anti-detachment protector plate. The lower protector plate covers the front of the corner, the connecting protector plate is connected to the lower protector plate and covers the outer side of the corner, and the upper protector plate is connected to the connecting protector plate and covers the back of the corner. A receiving groove is provided between the upper protector plate, the connecting protector plate, and the lower protector plate. The anti-detachment protector plate is connected to the upper protector plate and can be bent towards the receiving groove to the inside of the frame. A portion of the anti-detachment protector plate's structure is designed to abut against the inner side of the corner. By providing the anti-detachment protector plate, and ensuring that a portion of its structure abuts against the inside of the frame, this application restricts the movement of the anti-detachment protector plate, thereby preventing the corner protector from detaching from the corner of the frame. This ensures the corner protector is firmly wrapped around the corner, improving the stability of the corner protector after installation and reducing the risk of the corner protector falling off during transportation.

A garnish member (110) is disposed between a first interior member (6) and a second interior member (60) provided on a vehicle, both of which are supported by a frame (40) provided on the vehicle, and has a shield portion (111) that covers the edge of the first interior member and the edge of the second interior member, a plate-shaped garnish plate portion (112) that extends in the lateral direction, and a lateral portion (113) that extends in the lateral direction at a position behind the garnish plate portion and spaced apart from the rear side of the garnish plate portion. The frame has a base, a locking piece (117) that extends upward and is spaced apart from the front side of the base, and a separation preventing piece (118) that extends downward and is spaced apart from the front side of the locking piece. The upper end of the locking piece is positioned above the lower end of the separation preventing piece, and when the lateral portion is disposed between the locking piece and the base, the separation preventing piece is positioned in front of the lateral portion in plan view. Thus, the garnish member disposed between the two interior members is prevented from falling off.

The invention discloses a municipal pipeline transportation device which comprises a base used for containing a pipeline, limiting parts are detachably connected to the two sides of the base, at least two mounting blocks are mounted on the lower end face of each limiting part, universal wheels are mounted on each mounting block, a fixing groove allowing the pipeline to be placed in is formed in the base, and the limiting parts are detachably connected to the limiting parts. The two ends of the upper end face of the base are each provided with a supporting piece used for fixing a pipeline, and each limiting part is provided with a limiting piece used for abutting against the pipeline. According to the device, stable transportation of the pipeline can be achieved without large hoisting equipment, preliminary positioning of the pipeline is achieved through the fixing groove of the base and the supporting pieces at the two ends, multi-point fixing is conducted on the pipeline in cooperation with the limiting pieces on the limiting part, displacement, sliding or collision of the pipeline in the transportation process is effectively prevented, the labor intensity of workers is greatly relieved, and the transportation efficiency is improved. The construction period is shortened, and the method is particularly suitable for municipal pipeline installation operation in urban dense areas.

The invention discloses an expandable movable severe case shelter ambulance, and relates to the technical field of medical shelters, the expandable movable severe case shelter ambulance comprises a first-aid shelter used for accommodating a patient, the internal width of the shelter is not more than 2.2 m, the internal height of the shelter is not more than 2.5 m, the internal length of the shelter is not more than 7.5 m, and the shelter is applied to a medium-sized carrier; the problems that in the prior art, the internal space of a square cabin is small, only one to two patients can be borne in most cases, and the rescue efficiency is not high when major disasters occur or a large number of casualties occur are solved.
