This utility model discloses an outdoor unit for an air conditioner and an air conditioner having the same. The outdoor unit includes an air duct, fan blades, and an air guide ring. The cross-section of the air guide ring along the air outlet direction includes a first air guide section and a second air guide section. The airflow passes through the second air guide section and the first air guide section before exiting the outdoor unit. The cross-sectional projection of the first air guide section is an inclined straight line, while the cross-sectional projection of the second air guide section is a plurality of sequentially connected arcs. By sequentially arranging the air guide ring at the end of the air duct into a first air guide section and a second air guide section along the air outlet direction, and by setting the cross-section of the first air guide section as an inclined straight line and the cross-section of the second air guide section as a continuous arc segment, the first air guide section can better guide the airflow to the fan blades for driving circulation. The gap between the second air guide section and the fan blades is relatively small, increasing the airflow of the outdoor unit, reducing the rotational speed of the outdoor unit, thereby reducing the operating noise of the outdoor unit and improving the user experience.

The application provides an engine rotor blade tip multi-parameter design method, system and related device, relates to the rotor blade tip design technical field, and the design method comprises the following steps: S1, calculating a blade tip deformation amount, and drawing a blade tip thermal profile; S2, according to the blade tip thermal profile and the blade tip deformation amount, a blade tip final shape is drawn; S3, the deformation amount of a machine case is calculated, and a machine case cold profile is drawn; and S4, according to the machine case cold profile and the blade tip final shape, the cold installation gap of the blade tip and the machine case is determined. The application can ensure the safe operation of the engine under the condition of ensuring the performance requirements of the engine, and greatly improves the rationality of the gap design.

The application discloses a kind of dynamic scene under the motion control method of mobile manipulator and its application, using model predictive control, the state and control input quantity in future period are predicted, the deviation between the end pose of manipulator and target pose is added as a quadratic cost item to cost function, and set several collision points in the prominent position of mobile manipulator, the distance between these collision points and the obstacle in space is added as a penalty term to cost function, while the motion speed of robot, motion acceleration, the joint angle motion range of manipulator, joint angle acceleration and robot self-collision avoidance are added as constraint to model predictive controller, solve the optimal control input queue and act on the controller of robot, solve the defects, such as adaptability difference, stability deficiency of existing mobile manipulator in face of dynamic complex scene, improve the working stability of mobile manipulator robot.

This invention discloses an anchored metal-clad exterior wall insulation structure with a decorative cover, comprising a metal cover panel, an insulation board, and a groove. The metal cover panel has a recessed platform with a through hole drilled into it. A groove is formed inside the recessed platform, and a straw hat-shaped gasket and a cover are installed within the groove. The insulation board is bonded and fixed to the exterior wall, and the metal cover panel is wrapped around the outer surface of the insulation board. A reinforcing plate is provided between the insulation board and the metal cover panel. The metal cover panel is connected to the exterior wall by anchors, which penetrate the through hole and the insulation board. Sealant is filled between the anchors and the cover, and the cover is fixed in the groove by the sealant. This anchored metal-clad exterior wall insulation structure with a decorative cover has a reasonable structural design. By setting the recessed platform and the cover, the anchors are installed in the recessed platform, and the cover is used for concealment, ensuring both the fixing effect of the insulation board and the aesthetic appeal of the decoration.

This invention relates to the field of pumped storage power station construction, commissioning, and simulation technology, and particularly to a semi-physical hardware-in-the-loop (HIL) simulation method, system, electronic equipment, and storage medium for pumped storage units. The method includes: acquiring control logic-related data from the actual pumped storage power station unit and configuring this data into an electrical HIL simulation platform, enabling the HIL simulation platform to execute control logic consistent with the actual unit. This invention achieves high-fidelity replication of control logic by importing the actual unit's control logic and adapting it to the HIL simulation platform; it establishes a library of multiple commissioning scenarios to comprehensively verify the control logic; it drives synchronous closed-loop commissioning of primary and secondary modules, proactively identifying problems and reducing the risk and timeframe of actual unit commissioning; it quantitatively evaluates control logic performance from four dimensions, automatically detecting logic conflicts and timing deviations; and it provides data support for subsequent optimization scheme generation and secondary verification to form a closed-loop optimization, ensuring safe unit operation.
