An adjusting block is movably arranged at the top end of the placing block; a mounting ring is fixedly arranged on one side, close to the draw-off pump, of the placing block; the draw-off pump is communicated with a sand blasting hose, the other end of the sand blasting hose is communicated with a sand blasting nozzle, and a stabilizing assembly for ensuring the stability of the device is arranged at the bottom end of the mounting plate. By arranging the stabilizing assembly, after the device moves to a proper position, an electric telescopic rod pushes a stabilizing plate to move downwards, so that a friction rubber pad is in contact with the ground, meanwhile, a fixed pressing plate pushes a limiting plate through a sliding rod, so that the limiting plate compresses a functional spring, and the use stability of the device is guaranteed.

This application provides a method and apparatus for open-set skeleton action recognition based on outlier prototype learning. The method includes: constructing a neural network model; preprocessing human skeleton data by obtaining initial features through a multi-branch feature extraction network; processing the initial features using a classifier and a hypersphere feature mapper to obtain logical prediction values ​​for action categories and branch features; training the neural network model based on a training set; after the first iteration, optimizing the feature space of in-distribution samples using multi-class loss; synthesizing virtual outliers in the optimized feature space of in-distribution samples; optimizing the energy boundary by combining in-distribution samples and virtual outliers; after the second iteration, selecting the optimal model weights based on the combined performance of open-set recognition and closed-set classification on the validation set; and determining the action type and triggering the corresponding robot operation based on the energy score output by the trained neural network model and the action classification result.

The utility model provides a dilution device for solid food and drug detection, which relates to the technical field of food and drug detection and comprises a support frame, a center plate is fixedly mounted on the support frame, a swing frame positioned above the center plate is hinged to the support frame, and a hydraulic rod is fixedly mounted in the center of the upper surface of the swing frame in a penetrating manner. The grinding plate is arranged, solid food and medicine placed on the center plate are ground through descending of the grinding plate, the situation that the particle size is too small due to excessive grinding can be avoided through grinding, and therefore loss or instability of effective components of medicine is reduced; the uniformity of the medicine can be better controlled through grinding of the grinding plate, and dosage deviation caused by uneven grinding is avoided.

The utility model relates to the technical field of oil gas discharge pipelines, in particular to an oil gas discharge pipe. The oil gas discharge pipe comprises a pipe body, the inlet end of the pipe body is lower than the outlet end of the pipe body, a plurality of flow guide through holes are formed in the side face, close to the inlet end of the pipe body, of the pipe body, and the inlet end of the pipe body is communicated with a second flow guide piece used for flow guide. The sectional area of one end, close to the pipe body, of the second flow guide piece is smaller than that of the other end. By arranging the second flow guide part, enlarging the sectional area of the inlet end of the oil gas discharge pipe, reducing the overall flow rate of gas, further reducing the pressure drop degree and reducing oil gas loss, and by arranging the plurality of flow guide through holes, gas enters the pipe body from the plurality of flow guide through holes, a boundary layer formed by gas flow in the pipe body can be destroyed, and the oil gas loss is reduced. The flow rate of gas near the side wall is increased, and when the average gas speed on the whole pipeline section is not changed, the gas speed in the center can be reduced, so that the local pressure drop is reduced.

The utility model discloses a novel cast-off cell embedding box which comprises a base, a cover body is movably arranged on the base, a bulge is arranged on the cover body, a ring opening is formed in the base, the size of the bulge is matched with that of the ring opening, and when the cover body is buckled on the base, the bulge is positioned in the ring opening. A notch is formed in the ring opening. According to the novel cast-off cell embedding box provided by the utility model, a cell cluster is placed through the base, the base is buckled through the cover body, the cell cluster is placed through the ring opening on the base, and the aggregation of cells is ensured through the bulge on the cover body, so that the subsequent cell cluster embedding work is facilitated.

This invention relates to the field of fire resistance testing of building components, and particularly to an intelligent temperature-controlled fire resistance testing device for building partition wall components. It includes a test assembly, with a compatible component installed on the inner wall of the test assembly, and a penetration detection component installed on the bottom of the test assembly. The invention activates a second electric push rod, moving a storage box to a suspected gap on the unexposed side of the specimen, pushing a cotton pad into the unexposed side of the specimen. Simultaneously, the inner cylinder descends, driving a gap probe to penetrate the cotton pad and reach the gap. Continuous compression further penetrates the gap probe and sliding tube into the inner cylinder. A scale structure is used to determine the crack depth. When a penetrating crack or hole appears, the cotton pad ignites, which is then monitored by a smoke sensor, thus improving the fire resistance testing effect of the partition wall components.
