This utility model provides an integrated multi-functional smart speaker, relating to the field of smart speaker hardware structure technology, including a housing head, a housing body, and a housing base; the housing head is hemispherical, with an OLED display screen inside, and four microphone pickup holes on the outside of the housing head, the microphone pickup holes being covered with dustproof mesh. This utility model adopts a partitioned layout, with the communication area near the heat dissipation holes and antenna, the voice area near the pickup holes, and the control area located in the center, reducing signal interference and heat accumulation between modules, improving 4G / WiFi signal stability and voice pickup effect. It features high integration and low interference, solving the problem in existing smart speakers where 4G communication, WiFi hotspot, and voice interaction modules are mostly independent components with scattered layouts, resulting in large speaker size, severe internal signal interference, low integration of functional modules, and affecting 4G / WiFi signal stability and voice pickup effect.

The application discloses a kind of wisdom park dynamic analysis early warning platform, specifically related to wisdom park dangerous prediction field, including collection and reduction module, feature extraction module, matching mapping module, training classification module, prediction generation module and sorting intervention module, collection and reduction module is by obtaining multiple equipment operation and environmental state data, and according to equipment category and time stamp is arranged into uniform structure multivariate time series collection;By constructing the multivariate time series of fusion multiple equipment operation state and environmental information, extract disturbance feature and construct propagation path, combine risk classification model and dangerous prediction atlas, form a set of dynamic dangerous prediction and hierarchical intervention mechanism for multi-system linkage and nonlinear disturbance scene, to solve the problem that the existing wisdom park energy system lacks dynamic dangerous prediction ability for complex disturbance situation, cannot realize early identification and intervention to nonlinear energy risk.

The utility model discloses an AI acceleration computing server stable in operation, which comprises a support frame, a fan in a mounting frame is used for cooling a server main body to keep the server stable in operation, a worm on one side of the support frame is rotated to enable a worm gear meshed with the worm to drive a rotating rod to rotate, and the rotating rod rotates to drive the server main body to rotate. The angle of the server main body above the mounting plate can be adjusted through the rotation of the rotating rod, so that the server main body can face a worker, the fan which is moved out can be conveniently observed and diagnosed, and the convenience of maintenance is improved; a first lead screw above a server body is rotated, a first connecting frame in threaded connection with the first lead screw can drive a mounting frame to move, a draught fan on the inner side of the mounting frame can be moved out of the server body, meanwhile, the first connecting frame is located above the draught fan, an LED spotlight on the first connecting frame can illuminate the draught fan, and a second lead screw above the first connecting frame is rotated, so that the draught fan can be conveniently and rapidly moved out of the server body. The position of the LED spotlight in threaded connection with the second lead screw can be adjusted, and it is guaranteed that illumination is sufficient in a key area.

The utility model provides a kind of copper foil detection device of raw foil machine, including roof, the both sides of the one end of roof are uniformly provided with the mounting plate extending outward, and the bottom of roof is equidistantly provided with three sliding grooves, and the bottom of the movable plate between two mounting plates is equipped with laser marking assembly. Compared with prior art, the utility model has the beneficial effects as follows: detection, shading, marking three major modules closely cooperate, form the integrated closed-loop process of "detection-shading-marking", shading component real-time isolation external interference, CCD detection component fast scanning, laser marking assembly instant marking, when the second lead screw rotates, drive both sides first nut to drive shading component synchronous movement, when copper foil width changes, shading component can quickly adjust coverage, further refine shading area, continue to isolate external light interference in the process of copper foil operation, provide stable optical environment for CCD detection, guarantee image acquisition quality.

The utility model relates to the field of petroleum casing, relate to a kind of butt joint position triangle printing device of buttress thread petroleum casing, the printing device includes handle, baffle, taper lining, arc locating frame, positioning module, printing module.The taper lining of the printing device of the utility model can be naturally attached with full top thread, positioning module integrated telescopic base, compression spring and replaceable ball head, ball head simultaneously contacts thread tooth bottom and bearing side, realize three-dimensional space positioning, the distance of positioning ball head to baffle, the distance of the base of triangle steel stamp projection to positioning ball head are designed by formula, solve traditional experience positioning error, triangle printing position is accurate, and it can ensure that the base of triangle steel stamp projection is just at the tooth top position of thread, mark is clear, which is beneficial to subsequent butt joint observation.

This utility model relates to an arm mounting structure for unmanned aerial vehicles (UAVs), including a mounting bracket with an auxiliary mounting mechanism on the outside and an angle marking mechanism at the bottom. By providing the auxiliary mounting mechanism, this utility model effectively improves the fastening stability during the installation of the UAV arm and its safety and reliability during use. The nut, limiting washer, locking plate, marking rod, and baffle in the auxiliary mounting mechanism work together to achieve rapid fixing during tightening. Furthermore, the marking mechanism between the marking rod and the display ring enables intuitive identification of displacement. When the position shifts due to loose nuts or changes in force on the UAV arm, the mark left by the marking rod on the display ring provides a real-time warning, facilitating timely maintenance and resetting by the user, effectively avoiding flight abnormalities or even safety risks caused by loosening.
