This invention relates to a drainage method and system for CPR1000 nuclear power plants after overhaul and refueling, comprising: performing drainage preparation; upon receiving a drainage command, activating a first drainage path to drain the reactor pool; real-time monitoring of the reactor pool's water level changes and the drainage status of the first drainage path, and acquiring monitoring information of the reactor pool; determining whether the conditions for simultaneous drainage by two pumps are met based on the monitoring information of the reactor pool; if the conditions for simultaneous drainage by two pumps are met, activating a second drainage path to drain the reactor pool; real-time monitoring of the reactor pool's water level changes and acquiring real-time water level information of the reactor pool; determining whether the conditions for switching from two pumps to one pump drainage are met based on the real-time water level information of the reactor pool; if the conditions for switching from two pumps to one pump drainage are met, closing the first drainage path and maintaining the second drainage path to drain the reactor pool. This invention, by employing a dual drainage path during a stage with very large drainage volumes, can significantly reduce drainage time, significantly improve drainage efficiency, and effectively shorten the overhaul period.

The utility model provides a drainage time prediction device for a small sedimentation tank, which comprises a connecting pipe, the top end of the connecting pipe is connected with a mounting pipe, and the top end of the mounting pipe is connected with a flow meter; the two ends of the connecting pipe are connected with first flange plates, the connecting pipe is connected with the butt-joint pipe through the first flange plates, and a sealing mechanism is connected between the butt-joint pipe and the first flange plates. The gap between the second flange plate and the first flange plate can be reduced, and the gap generated when the device is in butt joint with the butt joint pipe of the sedimentation tank is increased.

To enable the acquisition of drainage construction methods that correspond to the drainage targets in the field. [Solution] The information processing device includes an acquisition means for acquiring target drainage volume, target drainage time, rainfall per unit time, and field images per unit time in a field where drainage work is to be carried out, and an estimation means for inputting the target drainage volume, target drainage time, rainfall per unit time, and field images per unit time acquired by the acquisition means as first input data to a trained model which has been trained to output drainage work information that can be carried out with the drainage target based on input data including the drainage target of the field, and performing estimation, and outputting drainage work information corresponding to the obtained first input data.

This invention provides a drain pump control method, control device, washing equipment, memory, and processor. The drain pump control method includes: determining the total effective drainage time of the dehydration stage, wherein the dehydration stage includes a pre-dehydration stage and a main dehydration stage, and the main dehydration stage includes multiple different speed sub-stages; controlling the drain pump to operate according to a preset drainage rhythm during the pre-dehydration stage, wherein the drainage rhythm includes the ratio of the drain pump's on time to its off time per unit cycle; determining the current speed sub-stage based on the current speed gear during the main dehydration stage, determining the drainage rhythm of the current speed sub-stage based on the current speed sub-stage, the total effective drainage time, and the preset total dehydration time, and controlling the drain pump to operate according to the current drainage rhythm. In this invention, the drain pump starts and stops according to the drainage rhythm, which can be dynamically adjusted according to actual conditions to meet drainage needs and reduce the noise of the drain pump operation.
