The invention relates to the field of anastomosis devices, in particular to a folding anastomat anvil capable of being inserted in a puncture mode. By splitting and folding the nail anvil, the cross section of the device is reduced on the premise of ensuring sufficient strength, width and diameter of the nail anvil, so that on one hand, the device can be put into a body cavity through the operation hole during an endoscopic surgery, and the difficulty of the surgery is reduced; on the other hand, in combination with an anti-stabbing puncture device, on the premise that the internal organs are prevented from being injured, the hollow internal organs needing to be anastomosed can be punctured and placed with the minimum wound, meanwhile, the hollow internal organs with bacteria and other pathogens inside are prevented from being directly communicated with the clean body cavity, and the infection risk is reduced. After anastomosis is completed, the device can be folded again, the nail anvil can be conveniently taken out of the hollow visceral organ, and the anastomotic stoma of the hollow visceral organ is prevented from being damaged.

The application relates to an engine rotating opposed-piston shaft cooling system and an engine, the shaft cooling system comprising a power output shaft and a nested shaft nested with the power output shaft, the power output shaft being provided with a power output shaft oil inlet channel and a power output shaft oil outlet channel along an axis, and the power output shaft being provided with a power output shaft oil inlet manifold and a power output shaft oil outlet manifold corresponding to the power output shaft oil inlet channel and the power output shaft oil outlet channel, the power output shaft oil inlet manifold and the power output shaft oil outlet manifold being provided with different cross sections and being provided with a power output shaft first piston and a power output shaft second piston; the nested shaft being provided with a nested shaft oil inlet channel and an oil outlet channel along an axis, and the nested shaft being provided with a nested shaft oil inlet manifold and a nested shaft oil outlet manifold corresponding to the nested shaft first piston and the nested shaft second piston; and the nested shaft oil inlet ring groove and the nested shaft oil outlet ring groove corresponding to the oil inlet oil pad and the oil outlet oil pad, and forming a nested shaft oil inlet main channel and a nested shaft oil outlet main channel.

The invention relates to the technical field of electric power communication security, and discloses a security data transmission system and method for an unmanned aerial vehicle nest and an electric power intranet, and the system comprises an unmanned aerial vehicle terminal, an unmanned aerial vehicle nest with a built-in electric power security Internet of Things card, a security access platform constructed based on a national secret algorithm, and an electric power intranet unmanned aerial vehicle management and control platform. The method comprises the steps that the unmanned aerial vehicle terminal collects data and uploads the data to the unmanned aerial vehicle nest, the unmanned aerial vehicle nest triggers the electric power security Internet of Things card to encrypt the data and transmits the data to the security access platform through the special APN, and after identity authentication, decryption, abnormity monitoring and permission verification, the data are securely accessed to the intranet management and control platform. According to the invention, the special APN isolation public network is adopted, and the national cryptographic algorithm full-process encryption and the main and standby dual-card redundancy design are combined, so that the security risk of the public network is blocked, the transmission stability is ensured, the power intranet access specification is adapted, and the inspection efficiency is improved.

The present invention discloses an integrated management and control system and method for an intelligent sample storage cabinet, including an intermediate database, a fuel management system, a database and a host computer, wherein the host computer and the database are connected to the fuel management system, and the intermediate database is connected to the fuel management system and each intelligent sample storage cabinet. The system and method can avoid various problems caused by human intervention and give full play to the functions of the intelligent sample storage cabinet.
