This invention discloses a roller brush device for cleaning gypsum board surfaces, relating to the field of gypsum board production technology. The device includes a cleaning roller, a slide block, a board frame, a support base, a linear actuator, and a limiting linkage. The cleaning roller is positioned above the gypsum board. The slide block is fitted onto both sides of the cleaning roller's shaft and slides in a groove on the board frame. The board frame is hinged to the support base. The linear actuator drives the board frame to swing around the hinge point, achieving arc-shaped lifting and lowering adjustment of the cleaning roller. The limiting linkage is hinged at both ends to the support base and the slide block, respectively, and, in conjunction with the groove, constrains the slide block's trajectory, ensuring the cleaning roller maintains a consistent contact angle with the gypsum board surface. A motor is fixedly mounted on the support base and drives the cleaning roller to rotate actively via a two-stage belt drive, without synchronously lifting or lowering with the cleaning roller. This invention effectively reduces drive load and energy consumption, provides a stable cleaning angle and high contact accuracy, and is suitable for continuous gypsum board conveying and cleaning operations.

This invention discloses a load time-series prediction method and system combining multi-scale slicing and masking. The method first preprocesses historical endogenous power load sequence data, historical exogenous covariate data, and exogenous covariate data to obtain preprocessed historical endogenous sequence data and multidimensional exogenous covariate data. Next, the preprocessed data is input into an endogenous multi-scale feature embedding module and an exogenous encoder, respectively, to extract multi-scale endogenous features and high-dimensional exogenous semantic features. Then, the multi-scale endogenous load features are fed into a fusion model to obtain a query vector, which, along with the high-dimensional exogenous semantic features, is input into an exogenous cross-attention module to generate the final fused features. Finally, the final fused features are passed through a feedforward network and a projection output layer to generate the power load prediction result for the future target time window. This invention solves the time alignment problem of heterogeneous exogenous power data and significantly improves the generalization and modeling capabilities for complex power grid dynamics.
