This application discloses an emergency rescue method, system, and platform based on multi-dimensional information fusion, relating to the field of emergency rescue technology. The method includes: an emergency rescue center receiving rescue request information from the location of an emergency event; coordinating information among all rescue parties based on the rescue request information and planning rescue routes based on multi-dimensional information; and alleviating traffic congestion along the rescue route by considering the destinations of vehicles in the congested area and planning alternative routes for these vehicles. The emergency rescue center coordinates multiple rescue parties based on the received location of the emergency event and plans the optimal rescue route. Furthermore, considering congested sections along the rescue route, it alleviates traffic congestion and plans alternative routes to avoid the location of the emergency event. This enables coordination among multiple rescue parties to be initiated immediately upon the occurrence of an emergency, and maximizes the time available for rescue parties to reach the emergency location, thereby improving rescue efficiency.

This invention belongs to the field of water conservancy engineering technology, specifically relating to a method for in-situ replacement of an aqueduct. The invention completes the in-situ replacement of the aqueduct through seven steps: safety assessment of the original aqueduct, temporary reinforcement of the risky aqueduct bridge pillars, permanent reinforcement of the aqueduct bridge abutments, construction of replacement aqueduct bridge pillars between adjacent risky aqueduct bridge pillars, prefabrication of the replacement aqueduct body and demolition of the risky aqueduct body, and installation of the replacement aqueduct body along with auxiliary installations such as waterstops and railings. By employing the technical solution of this invention, the replaced aqueduct shares the same axis as the original aqueduct. Therefore, during the demolition and reconstruction process, the existing aqueduct's operational time is maximized, minimizing losses.

The invention relates to the technical field of metal heat treatment liquid, and discloses oil-water separation type overspeed quenching oil and a preparation method thereof, and the oil-water separation type overspeed quenching oil comprises base oil, polyisobutene, a trapping agent, a coagulation agent, oil-soluble divalent metal organic acid salt and an additive. According to the invention, a synergistic response system composed of a trapping agent, a coagulation agent and an oil-soluble divalent metal organic acid salt is introduced into an oil product. When water invades, the synergistic response system is subjected to chemical processes of hydrolysis, ion bridging and coagulation. According to the technical scheme, the quenching oil has a rapid and thorough self-triggering oil-water separation function, oil product emulsification and performance reduction caused by water pollution are effectively avoided, meanwhile, the system is chemically inert in a water-free state, and the original overspeed cooling performance of the oil product is not affected. The invention further provides a preparation method of the quenching oil, and the preparation method is simple in process and easy to control.

This utility model relates to the field of oil leakage detection technology, and in particular to an oil leakage detection device for a lubricating oil air-cooled radiator filter element. It includes a filter element body installed on the circulating oil pipe of the radiator body, an oil pump for controlling the circulation of the circulating oil pipe on the circulating oil pipe, a collection cylinder located outside the filter element body, at least two proximity switches cooperating with a sensing element, and a controller. The upper end of the collection cylinder is open for collecting leaked oil from the filter element body. A buoyancy rod is slidably connected inside the collection cylinder via a connecting pipe, and a buoyancy ball is connected to the lower end of the buoyancy rod. This utility model utilizes the buoyancy of the buoyancy ball to drive the sensing element to contact the proximity switch at the corresponding position, thereby realizing a multi-position detection and graded early warning mechanism. This avoids misoperation or overreaction caused by single threshold detection, provides operators with more reasonable response time and decision-making basis, and reduces the workload of on-site personnel inspection.
