A method and system for strategically solving an innovative design problem are provided. A target analysis tool is determined according to a to-be-solved problem. An initial model is generated based on the target analysis tool. A target model is determined according to an interaction relationship among elements in the initial model and the target analysis tool. A problem characterization result of the target model is generated according to a preset interaction relationship. Retrieval information is generated according to the problem characterization result, based on which the retrieval is performed in a preset database to obtain target data. Different analysis tools can be used to analyze different to-be-solved problems. The retrieval is performed based on the problem characterization result to obtain the solution to the to-be-solved problem.

A quick-detachable connecting device with a simplified thread structure includes a top nozzle, a connecting tube sleeve, a locking tube and a locking piece. The top nozzle is provided with a through hole, in which the connecting tube sleeve is assembled. The locking tube is accommodated in the through hole. An outer peripheral surface of the locking tube is provided with a second stopping structure, and an inner peripheral surface of the connecting tube sleeve is provided with a first stopping structure fitting the second stopping structure. The locking piece is movably arranged on the locking tube for circumferentially limiting or releasing the locking tube. A connection method using such connecting device is also provided.

A sea creature cleaning robot for an intake tunnel for a nuclear power plant includes a frame, cutter assemblies, and walking wheel assemblies; the frame is used for mounting and fixing cutter mounting seats and crawler wheels; the walking wheel assemblies mounted on the frame enable the entire device to normally walk in a tunnel; the cutter assemblies control the height of cutters by means of hydraulic cylinders to make the cutters contact the inner wall of the tunnel, and the hydraulic cylinders drive the saw-toothed cutters to move back and forth to remove sea creatures attached to the inner wall of the tunnel; the cutter assemblies are uniformly distributed on the frame, so as to ensure full coverage of the cleaning range of the cross section of the tunnel. The robot can clean sea creatures in tunnels in place of manual work to significantly improve the cleaning efficiency.
