This invention provides a MEMS packaging structure, including a first substrate and a second substrate. The second substrate and the first substrate are bonded together at a predetermined distance to seal the bonding area into a closed microvacuum cavity. A microvacuum gauge is disposed inside the closed microvacuum cavity to monitor the vacuum level inside the cavity. By incorporating a microvacuum gauge within the MEMS packaging structure, the vacuum level inside the vacuum cavity where the MEMS sensor is located can be monitored in real time and in situ. This allows for determination of whether the vacuum level inside the cavity is within the range required for normal operation of the MEMS sensor, providing timely early warning and enabling appropriate countermeasures to be taken promptly to ensure the continuous and normal operation of the sensor.

The invention relates to the technical field of overhead man-riding auxiliary structures, in particular to a steel wire rope quick lifter applied to an overhead man-riding device, which comprises a stand column and two lifting units horizontally and oppositely arranged on two sides of the stand column, and the lifting units are used for lifting a steel wire rope; the lifting unit comprises a back plate and a guide groove formed in the side wall of the back plate, the guide groove is composed of an arc-shaped groove and a right-angle groove, the top of the right-angle groove is horizontal, and two pulleys are arranged in the guide groove in a sliding mode; by directly replacing the positions of the two riding wheels, the riding wheel needing to be replaced can be directly separated from the steel wire rope, and the other riding wheel is used for lifting the steel wire rope, so that the riding wheel needing to be replaced can be directly operated conveniently, and the steel wire rope does not interfere with the riding wheel any more; by means of the mode, maintenance and replacement of the riding wheel can be achieved on the premise that continuous work of the steel wire rope is guaranteed.

This utility model discloses a rice seed screening and processing device, relating to the field of rice seed screening technology. It includes a soaking tank and a sieve cylinder. An inlet pipe and an outlet pipe are fixedly installed on the side of the soaking tank. A support unit, a traction unit, and a discharge unit are fixedly installed inside the soaking tank. The support unit is rotatably connected to both ends of the sieve cylinder. A feed hopper, a stirring unit, and a debris collection unit are fixedly installed on the support unit. A spiral plate is fixedly installed on the inner wall of the sieve cylinder. The beneficial effects are that the rotating sieve cylinder and spiral plate agitate the rice seeds, and the flexible movement of the rotating brush reduces seed accumulation, facilitating seed dispersion. The airflow from the vents carries light, floating debris such as empty husks from the rice seeds to the upper part of the liquid, effectively improving the efficiency of rice seed screening. The liquid and the gas sprayed from the vents reduce mutual collision damage during the screening process, ensuring the integrity of the rice seeds and the quality of the screening.

This application relates to the field of power distribution equipment technology and provides a high-voltage distribution box and electrical equipment. The high-voltage distribution box of this application includes a housing, and a power distribution circuit and a BMS component disposed within the housing for connection to external modules. The power distribution circuit includes a common node, an output circuit, a charging circuit, and a power supply circuit. At least one of the power supply circuit, output circuit, and charging circuit has multiple branches connected in parallel between the common node and the corresponding external module, and the BMS component is connected to the multiple branches via sampling harnesses. The high-voltage distribution box of this application, through the arrangement of multiple parallel branches in the power distribution circuit, ensures that when one branch fails, the other branches can still operate normally, maintaining the normal operation of the power distribution circuit for a short period. Simultaneously, the BMS component can monitor the operating status of each branch to facilitate subsequent maintenance work, thereby improving the reliability of the power distribution circuit.

The application discloses a novel plugging and flow guiding robot applied to pipeline emergency repair operation, relates to the technical field of oil and gas pipeline emergency repair, and comprises a sealing flow guiding device capable of guiding and dredging the medium conveyed in a pipeline, and two traction support units symmetrically arranged on the two sides of the sealing flow guiding device. Each traction support unit comprises a robot power device and a support part. Universal couplings for realizing bend self-adaption are arranged between the robot power devices and the support parts on the same side and between the support parts and the corresponding sides of the sealing flow guiding device. The main function of the device is to implement dynamic plugging at the pipeline rupture position. After a rupture crack is found, the robot travels to the position, the air bag of the plugging system is inflated through an inflation pump, the sealing air bag is inflated to tightly contact the pipeline, a sealing area is formed at the rupture position, and the liquid in the pipeline flows away through the small bypass flow guiding pipe.
