This utility model relates to the field of warning equipment technology, specifically a mobile multifunctional intelligent warning device. It includes a base, a main pole mounted on top of the base, a control box on the main pole, a warning panel, a monitoring camera, and a photovoltaic panel. The bottom of the base has a moving component and a foot-operated brake. The moving component includes a rear steering wheel and a front moving wheel, the front moving wheel being connected by an axle. The foot-operated brake drives the brake plate to limit the brake wheel by pressing an L-shaped pedal, and is fixed by a positioning pin inserted into a positioning hole. The photovoltaic panel supplies power to a battery. The control box controls the warning panel to display warning information and the monitoring camera to collect environmental data. This device solves the problems of inconvenient movement and unstable fixation in existing warning devices, achieving convenient movement, intelligent warning, and remote monitoring.

This invention relates to a continuous flow stepwise crystallization method and system for preparing micro / nano HMX at the microscale. It includes the following steps: (1) dissolving HMX in a solvent to form an HMX solution, and mixing the solvent and antisolvent to prepare a crystallization transfer solution; (2) flowing the HMX solution prepared in step (1) and the antisolvent into a primary micro-mixing crystallization unit at a desired flow ratio to generate a mixed-crystal HMX suspension with a mixed crystal particle size of 400 nm–60 μm; (3) flowing the mixed-crystal HMX suspension flowing out of the primary micro-mixing crystallization unit and the crystallization transfer solution prepared in step (1) into a secondary micro-mixing crystallization unit at a desired flow ratio, and secondary crystallizing the mixed-crystal system to obtain a pure β-HMX suspension with a crystal size in the micrometer range. This invention can obtain micro / nano β-HMX with high crystallization degree and high crystal purity by changing the mixing conditions and residence time in the secondary crystallization unit; the two-step crystallization method can meet the requirements for continuous and controllable preparation of high-quality elemental β-HMX with smaller crystal size and higher crystal purity.

The utility model discloses a pet defecation flushing device relates to pet article technical field, including drainage mechanism, the top of drainage mechanism is provided with the flushing mechanism, the flushing mechanism includes the column type vertical pole, the top fixed mounting of column type vertical pole has the bottom disc, the top fixed mounting of bottom disc has the water outlet cylinder, the inner chamber fixed mounting of water outlet cylinder has electric control valve, the input of electric control valve is fixedly connected with the water inlet pipe. The utility model discloses the bottom disc annular array of flushing mechanism opens a plurality of water outlets, and water source is controlled after passing through electric control valve, and from water outlet cylinder vertical downward annular flow is passed through water outlet, and even flows down along the outer wall of column type vertical pole, and only need to press the flush button to trigger electric control valve, realizes quick start and stop, and the water flow annular flow and down along the vertical pole, avoids splashing everywhere, reduces ground water stain residual, directly flushes the contaminated area to the characteristic of pet urine adhering vertical pole, improves the cleaning efficiency.
