The invention provides a revenue service rule configuration generation method and device, equipment and a storage medium, and relates to the technical field of Internet. The method comprises the following steps: receiving a revenue business demand input by a user through a natural language; performing assembly based on the revenue business demand and the DSL grammar definition to generate a first prompt word; generating a first DSL document according with the DSL grammar definition through the target large model according to the first cue word; and converting the first DSL document, generating a first revenue service rule configuration, and storing the first revenue service rule configuration. The smooth conversion between the natural language and the service rule is realized, the complexity of the DSL is shielded, the process of manually configuring a large number of tedious parameters is avoided, and the service configuration efficiency is improved.

This invention provides a convertible roller skate, comprising a shoe body, fixed pulleys, a first rotating seat, a second rotating seat, a movable pulley assembly, and a locking mechanism. The shoe body includes a sole, with the fixed pulleys supported at the front end of the sole, the first rotating seat supported at the rear end of the sole and pivotally connected to the sole, and the second rotating seat pivotally connected below the first rotating seat. The movable pulley assembly includes several movable pulleys, each corresponding to a second rotating seat. The movable pulleys are adapted to rotate around a second rolling axis l2. The first rotating seat rotates to switch the orientation of the movable pulley assembly, and the second rotating seat rotates to keep the second rolling axis l2 parallel to the first rolling axis l1. The locking mechanism includes two locking grooves and a locking part, the locking part engaging with the locking grooves to restrict the rotation of either the first or second rotating seat. This invention allows for changing the arrangement direction of the movable pulley assembly by rotating the first and second rotating seats, thereby converting the skate's form.

This invention relates to the field of dried bean curd production and processing technology, and provides a dried bean curd cutting device, including a first straight section and a second straight section arranged vertically. Both the first and second straight sections have built-in cutting mechanisms for cutting the dried bean curd into pieces. The dried bean curd cutting device provided by this solution can continuously cut in two directions. After completing one direction, a turning mechanism is used to switch to the other direction for cutting, achieving a smooth transition in the bean curd transport position. This not only ensures the continuity of the bean curd cutting process but also avoids problems such as jamming and blockage during transport, further improving the stability and reliability of the equipment. It essentially achieves the goal of continuous operation, with a short dwell time during transitions, thus improving the cutting efficiency of the equipment.
