This invention discloses a liquid crystal prism and a display device. The liquid crystal prism includes an optical region and a non-optical region. The non-optical region includes a first frame region and a bonding pad. The liquid crystal prism includes a substrate, multiple electrode groups, and a lead group. The electrode groups include multiple driving electrodes located in both the optical and non-optical regions. The lead group is located in the non-optical region and includes multiple leads, with the driving electrodes and leads disposed on different layers. The liquid crystal prism also includes an auxiliary lead group, at least part of which is located in the first frame region and includes multiple auxiliary leads electrically connecting the leads to the bonding pad. The technical solution of this invention, by providing an auxiliary lead group in the liquid crystal prism, allows for flexible connection positions between the auxiliary leads and the bonding pad, enabling flexible placement of the bonding pad. For example, the bonding pad can be placed in the middle of the first frame region, reducing the pressure risk when the bonding pad is subsequently connected to a flexible circuit board via thermoforming.

This utility model discloses a sidewall water storage cavern for the operation and maintenance of a tunnel central drainage ditch, belonging to the field of tunnel construction. It includes a tunnel central drainage ditch, with multiple water storage caverns spaced along the tunnel sidewall. Each water storage cavern has an entrance / exit pre-installed at its upper part, connecting to the tunnel interior, and a sealing door is provided at each entrance / exit. The water storage caverns are connected to the tunnel central drainage ditch via a buried transverse water diversion branch ditch. The bottom elevation of the water storage cavern is lower than that of the tunnel central drainage ditch. By excavating caverns in the tunnel sidewall to construct water storage caverns and connecting them to the tunnel central drainage ditch via buried transverse water diversion branches, a tunnel central drainage ditch inspection passage is provided for workers through the water storage caverns and the buried transverse water diversion branches. This allows conventional tunnel inspection manholes to be moved from below the tunnel surface to the tunnel sidewall, effectively avoiding the spatial conflict between tunnel central drainage ditch maintenance operations and traffic within the tunnel.

This utility model provides a stepped GIL (Gas Injection Line) pipeline platform, relating to the field of GIL pipeline technology. It includes a support platform comprising support columns and platform beams, with multiple sets of support columns arranged in a stepped configuration, and platform beams positioned between the support columns. A pipeline support structure supports GIL pipe sections and includes a bracket structure and an adjustment structure. The bracket structure is mounted on the platform beams, and the adjustment structure allows for adjustment of the bracket structure to support the GIL pipe sections. A protective structure is located on the platform beams and includes a channel plate and protective baffles. The channel plate is located on both sides of the platform beams, and the protective baffles are mounted on the channel plate. This utility model offers flexible support column placement and good adaptability. The pipeline support structure supports GIL pipe sections, the adjustment structure allows for adjustment of the bracket structure according to the number and position of GIL pipe sections, and the protective structure enhances the protection of GIL pipe sections and personnel, resulting in a higher safety factor.

The utility model relates to the technical field of liquid cooling plates, in particular to a friction welding liquid cooling plate and a power box, the friction welding liquid cooling plate comprises a substrate and a cover plate, the substrate is provided with a first through hole, the cover plate is provided with a boss, the boss penetrates through the first through hole, and the part, extending into the first through hole, of the boss is connected with the substrate. According to the friction welding liquid cooling plate, the boss is matched with the first through hole, a new friction welding seam can be formed between the base plate and the cover plate, holes do not need to be formed in the cover plate, and a continuous planar area with a large area can be conveniently formed on the cover plate and used for installing components or arranging accessory structures; moreover, as the new friction welding seam is located at the position where the boss extends into the first through hole, the influence of all structures on the surface of the cover plate is small, the arrangement position is relatively flexible, and the new friction welding seam can be conveniently arranged close to the flow channel, so that the compression strength of the flow channel is improved, and the deformation risk and the leakage risk are reduced.

The utility model relates to the field of compressors, and provides a reciprocating compressor and a refrigerator. The reciprocating compressor comprises an air cylinder, a piston, an air supplementing opening and an air supplementing valve, the air cylinder comprises a side wall and an end cover, and the end cover is arranged at one end of the side wall and provided with an air inlet and an air outlet; the piston reciprocates in the air cylinder, and a cavity used for compressing gas is defined by the side wall, the end cover and the piston. The air supply port can be flexibly arranged on the end cover or the piston, and the air supply valve is arranged on the air supply port to control opening and closing of the air supply port. Opening and closing of the air supplementing opening can be controlled through the air supplementing valve, specifically, the air supplementing opening is opened only at the appropriate time, and therefore the air supplementing pressure loss is reduced.
