This utility model discloses a guide structure for preventing door deviation and a disinfection cabinet using the same, relating to the field of mechanical equipment technology. It includes a door frame and a door body rotatably connected to the door frame. The door body has guide protrusions arranged along the rotation path of the door body. During the rotation and closing of the door body, the guide protrusions abut against the side of the door frame, guiding the rotation of the door body and preventing it from deviating in the left-right direction. It also includes a cabinet body and a cabinet door rotatably connected to the cabinet body. The cabinet door has the door body structure, and the cabinet body has the door frame structure. Through the innovative design and reasonable arrangement of the guide protrusions, the existing door deviation problem is effectively solved, demonstrating significant practicality and innovation. It can bring a better user experience and performance improvement to various devices with door body structures and related application scenarios.

The application provides a karst tunnel large cave automatic water discharge pressure reduction device and method under heavy rainfall conditions, which comprises a filtering mechanism, the top end of the filtering mechanism extends into the cave, the bottom end of the filtering mechanism is connected with a cylindrical mechanism, the end of the cylindrical mechanism away from the filtering mechanism is fixedly connected with the top end of a tunnel mechanism, the high end of the cylindrical mechanism is connected with the inlet of a fine drain pipe, the outlet of the fine drain pipe is connected with the tunnel mechanism, the low end of the cylindrical mechanism is connected with a coarse drain mechanism, and the other end of the coarse drain mechanism is connected with the tunnel mechanism. On the one hand, the hydrogeological environment of the tunnel is not damaged, the underground water balance is protected, the automatic grading discharge of the cave underground water is realized, the water pressure outside the tunnel structure is reduced, the tunnel structure performance is protected, and the unreasonable stress of the tunnel structure caused by excessive water pressure is avoided to prevent the structure damage. On the other hand, the integrity of the secondary lining structure of the tunnel is not damaged, and the structure performance reduction caused by local stress concentration is avoided.

The application discloses a kind of based on porous super-hydrophobic material ventilation air film layer drag reduction device, method and ship, belong to air film drag reduction technical field;Device includes drag reduction component, gas supply module, data acquisition module and control module, drag reduction component includes porous super-hydrophobic plate and the non-porous material super-hydrophobic plate located downstream thereof;The porous super-hydrophobic plate is built-in with several air injection hole air passage, the air inlet of air passage is communicated with gas supply module, gas is ejected from air injection hole by air passage, then it is output to its outer wall surface by the small air hole of porous super-hydrophobic plate, and stable air film layer is formed by flowing through downstream non-porous material super-hydrophobic plate;Data acquisition module transmits collected data to control module, and control module judges whether air film meets requirements according to each data, and if not satisfied, corresponding gas supply amount is adjusted.The application solves the problem that uniform ventilation of the whole ship body is difficult to realize due to external water pressure in the prior art;Meanwhile, the injection rate is regulated.
