The application discloses a power cabinet with a leakage monitoring structure and relates to the technical field of power cabinets.The power cabinet with the leakage monitoring structure comprises an equipment frame, a supporting plate is fixedly arranged in the equipment frame, an electric push rod is fixedly arranged on one side away from an output end of the equipment frame, and a limiting device comprises a square block, a circular plate, a wiring head, an electric wire, a fixing plate, a limiting block, an L-shaped plate, a square block and a wiring frame.The square block is slidably arranged above the supporting plate, the wiring head is fixedly penetrated through inner and outer walls of the square block, and the power cabinet with the leakage monitoring structure can be detected only after being limited, so that the power cabinet can be overhauled or operated in a safe state, the safety of operators is maximally ensured, and the internal electrical equipment can be better protected and the risk of equipment damage caused by leakage can be reduced.

The application belongs to the technical field of medical supplies, and particularly relates to a lumbar cistern drainage and medicine administration device which comprises a connecting seat, a liquid storage bag, a catheter, a guide puncture needle and a puncture needle. After the insertion end of the guide puncture needle enters the subarachnoid space, the temperature of the cerebrospinal fluid increases the temperature of the first limiting part, and then the first limiting structure becomes an arched curve shape, and then the side wall of the first limiting part arches, and then the catheter in the subarachnoid space is prevented from moving out of the subarachnoid space, and at the same time, the catheter reserved below the partition plate is moved outward, and then the development needs are compensated through the reserved catheter, and then the catheter is prevented from being separated from the subarachnoid space. When the catheter needs to be taken out, low-temperature normal saline is slowly injected into the catheter through the liquid storage bag, and then the temperature of the catheter is reduced, and then the temperature of the first metal sheet is reduced, and then the first limiting structure becomes a straight line shape, and then the first limiting part is contracted, and then the catheter is conveniently pulled out.

The utility model relates to microorganism strain proportioning technical field discloses a kind of experimental devices for microorganism strain proportioning, including jar body, installation position is opened in jar body;Mixed component, mixed component is set in jar body, and mixed component is used to proportion and mix to microorganism strain, and mixed component includes driving motor, movable frame, auger shaft and fixed block, driving motor is fixedly connected with jar body, movable frame is set in jar body, movable frame is drivingly connected with driving motor, auger shaft array is set in jar body, each auger shaft is drivingly connected with driving motor, multiple fluid effects are formed by the cooperation of mixed component internal parts, under the cooperation of multiple fluid effects, avoid in stirring Large amount of foam covers liquid surface to hinder oxygen dissolving, lead to aerobic bacteria growth is limited;Foam layer hinders liquid flow, causes local strain or nutrient concentration difference;Foam occupies reactor space, reduces actual utilization rate and other problems.

This utility model discloses a sample box for metallurgical temperature measurement and sampling, comprising a first shell and a second shell; each of the first and second shells has a semi-cavity structure on its opposite side, and a semi-open structure on the side of each semi-cavity structure. The semi-cavity structure and the semi-open structure, after being connected to the first and second shells, respectively form a sampling cavity and a sampling port communicating with the sampling cavity. The first and second shells are connected by a positioning structure; the positioning structure includes a positioning groove and a positioning protrusion, and an internal and external pressure balance hole communicating with the sampling cavity is provided at the connection between the positioning groove and the positioning protrusion. This utility model effectively prevents leakage of high-temperature molten metal through the sealing structure formed by the annular step and the annular protrusion, enhances the stability of the shell connection by combining the positioning connection method, and the pressure balance hole automatically adjusts the internal and external pressure of the cavity, avoiding the obstruction of sample flow due to negative or positive pressure.

The utility model relates to the technical field of quartz sand processing, in particular to a powder iron remover for quartz sand processing, which comprises a support and an iron removal component. The iron removal assembly comprises a magnetic cylinder, a turning shaft, a collecting bin, a scraping plate and a driving component, during use, quartz sand is added to the high side of the magnetic cylinder, the quartz sand slides to the low side of the magnetic cylinder under the action of gravity, and in the process, the driving component is started to drive the magnetic cylinder and the turning shaft to rotate, so that the quartz sand is removed. The magnetic cylinder drives the quartz sand in the magnetic cylinder to continuously rotate, so that the quartz sand powder fully rolls and rubs on the inner wall of the magnetic cylinder, the contact opportunity of iron impurities and the inner wall of the magnetic cylinder is increased, and the iron removal effect is further improved; and meanwhile, the quartz sand powder in the magnetic cylinder is turned over through rotation of the turning shaft, the contact area of the quartz sand powder and the inner wall of the magnetic cylinder is further increased, and the adsorption efficiency of the iron impurities is improved.
