The invention relates to the technical field of concrete strength detection, and particularly discloses a concrete strength detection device and method based on hydraulic engineering supervision. The concrete strength detection device comprises a pressure bearing mechanism which is arranged at the bottom of the inner side of a machine body and is used for being matched with a downward pressing mechanism to detect the compressive strength of a concrete test piece; the driving mechanism drives the limiting mechanisms arranged in an annular array to clamp the concrete test piece from the side wall of the concrete test piece, so that the center of the concrete test piece is vertically aligned with the center of the bearing plate, and the downward pressure of the downward pressing mechanism on the concrete test piece is stably distributed on the concrete test piece; the detection precision is improved, repeated adjustment by workers is not needed, the detection efficiency is improved, the position of each limiting plate is conveniently mastered through the monitoring assembly and the identification assembly, the position of the deviated limiting plate is adjusted through the adjusting assembly, and the concrete compressive strength can be conveniently detected for a long time.

The invention discloses a control method for improving the drying uniformity of a heat pump clothes dryer, and relates to the technical field of clothes dryers, and the control method specifically comprises the following steps: dividing the drying of the clothes dryer into three stages, firstly setting switching data of the clothes dryer in different drying stages, namely running time T, switching time A and switching humidity H, and in the first stage, setting the switching data of the clothes dryer in the different drying stages, namely the running time T, the switching time A and the switching humidity H; an inner barrel of the clothes dryer operates according to the rotating and stopping beat a; when the running time T is larger than A, a second stage is started, and in the second stage, the inner barrel of the clothes dryer runs according to the rotating and stopping beat b; when the running time T is larger than A and the detected humidity value RH1 of the clothes is smaller than or equal to H, a third stage is entered, and in the third stage, an inner barrel of the clothes dryer runs according to the rotating and stopping beat c; in the drying process of the heat pump clothes dryer, the rotating and stopping rhythm of the inner barrel is adjusted by detecting the sampling value of the humidity sensor, so that the distribution of clothes in the clothes dryer is adjusted, and finally the drying uniformity of the clothes is improved.

This invention belongs to the technical field of geotechnical engineering monitoring, and relates to a geotechnical engineering monitoring trend prediction system based on big data. It includes the following modules: a data acquisition module for generating real-time front-end differential response signals; a threshold judgment module for generating local early warning trigger events; an array activation module for converting into a directional activated local high-sensitivity monitoring array; a data integration module for generating chain response data clusters; a vector analysis module for constructing spatial damage vector chains; and a decision output module for outputting structured early warning decision instructions. This invention addresses the problem that traditional monitoring points are often isolated, lacking the ability to intuitively reveal the propagation path and speed of damage through intelligent, interconnected spatial array sensing driven by physical events.
