This invention relates to the field of hydrogen production via water electrolysis, and particularly to a shutdown pressure stabilization control method, apparatus, electronic device, and storage medium. The method includes: upon receiving a shutdown signal, initializing the operating state of the control valve group; during the pressure relief phase, acquiring measured values ​​of the liquid levels on the hydrogen and oxygen sides, as well as the system pressure; based on the difference in liquid levels on both sides, cyclically adjusting the opening and closing states of the pressure-holding valves on both sides to maintain the difference within a preset range; until the system pressure is lower than the target holding pressure, closing the pressure-holding valves on both sides to enter the pressure-holding phase. This application utilizes the regulating valves and pressure-holding valves on both sides of the hydrogen and oxygen sides as actuators, and uses the measured system pressure and liquid level values ​​as control references to achieve pressure and liquid level stability during shutdown pressure holding. This solves the problem in the prior art where relying solely on the regulating valves on both sides of the hydrogen and oxygen sides is insufficient for pressure regulation, making it difficult to achieve pressure balance and stability during shutdown pressure holding.

The utility model provides a kind of anti-pressure sore bedpan device for ICU patient, including support, the accommodating groove recessed in the support, and be equipped in the accommodating groove two-way drive assembly and cushioning component, the cushioning component includes the support platform connected with the two-way drive assembly, the bedpan placement slot recessed in the support platform, and detachably equipped in the bedpan placement slot bedpan, the bedpan includes rigid body part, and be equipped on the rigid body part elastic part, the bionic curved surface for adhering human body hip is formed on the elastic part.The anti-pressure sore bedpan device for ICU patient in the utility model, the pressure of sacrococcygeal part and ischial tuberosity is dispersed by the elastic part on bedpan, and the unilateral pressure concentration of hip when long-term bedridden patient is in toilet is reduced by two-way drive assembly, to avoid pressure sore.

The application provides a FRP reinforcing device and method for inhibiting brittle failure, relates to the field of beam reinforcing and repairing, and aims at the problem that the FRP plate is easy to peel off from the concrete, leading to reinforcing failure. The buckle is used to apply active pressure to the FRP plate to increase the friction between the FRP plate and the concrete, and improve the utilization rate of the FRP. A release mechanism is installed at the end of the FRP plate. The clamp and the elastic piece of the release mechanism are used to elastically constrain the end of the FRP plate, release the displacement of the end of the FRP plate, slow down the brittle peeling failure of the FRP plate, and effectively improve the ductility of the FRP plate and the concrete beam.
