This invention relates to the field of electrical equipment cabinet technology, specifically to an energy-saving and heat-dissipating power electrical control cabinet. The cabinet includes a control unit with a first partition dividing the space within it into an air intake chamber and an equipment chamber. A heat dissipation mechanism is also provided within the control unit, including an air intake assembly located within the air intake chamber. This assembly comprises a main air intake duct, several air outlet ducts, and several mounting plates. Several mounting holes are provided on the side of the first partition near the air intake chamber. Through holes are provided on the mounting plates, and fixing bolts are installed within these through holes and screwed into their corresponding mounting holes. This energy-saving and heat-dissipating power electrical control cabinet overcomes the problem of insufficient localized temperature reduction in existing heat dissipation methods. Furthermore, the position of the heat dissipation vents can be flexibly adjusted to address the issue of adjusting the position of equipment within the power electrical control cabinet.

The utility model relates to pearl processing screening technical field discloses a kind of round grain screening devices for pearl processing, there is side plate in the both sides of bottom plate, and there is oblique feeding inclined plate connected with side plate in oblique upper side. Bottom plate is equipped with screening assembly, and it includes inclined guide plate and screening plate. Screening plate two ends are connected with side plate, and also be inclined, from top to bottom, and it is divided into three zones of small aperture, medium aperture and large aperture. By designing multistage aperture screening plate, it can be automatically classified and screened according to the roundness and size of pearl, reduces the dependence of manual operation, not only improves screening efficiency, but also avoids the error caused by human factor, ensures the accuracy and consistency of screening result. The inclination angle of screening plate is adjustable, and screening plate and side plate are detachably connected, and this design makes the device easily adapt to different types and sizes of pearl screening requirements, improves the flexibility and versatility of equipment.

This invention discloses a method for automatically generating structured meshes and terrain for canals based on parametric modeling. This method involves parametrically inputting canal design parameters and original terrain data, and sequentially executing five core steps: original terrain interpolation and fusion, generation of straight channel meshes and terrain, generation of curved channel meshes and terrain, seamless stitching of straight and curved meshes with terrain, and mesh-terrain format conversion and structured reconstruction. The entire process is automated using MATLAB code. This invention addresses the pain points of existing technologies, such as distortion in straight-curved stitching, low automation, and poor digital twin adaptability. The generated structured mesh is accurately adapted to the 3D terrain and can be directly imported into numerical simulation software and digital twin platforms. It provides high-precision data support for canal engineering design, hydraulic characteristic analysis, and digital twin system construction, and is suitable for engineering needs involving multiple sections of alternating straight and curved artificial canals.

The application discloses a non-invasive ECG signal auxiliary monitoring and alarm system and method, relates to the fields of electrocardiogram signal automatic analysis and diagnosis and digital image processing, and comprises a video stream acquisition module, a picture interception module, a denoising and binarization module, a key point monitoring module, a labeled video stream module and a video stream display module. The video stream acquisition module acquires a video stream from an electrophysiological recording system; the picture interception module intercepts signal pictures at preset positions in the video stream; the denoising and binarization module pre-processes the signal pictures to obtain clean signal pictures; the key point monitoring module detects preset key points in the signal pictures according to pixels to obtain detection signals of the key points; the labeled video stream module detects the key points and gives a prompt; and the video stream display module displays the signal pictures in the form of the video stream on a result display screen, so that a user can observe in real time.
