The utility model relates to the technical field of dry-type transformers, in particular to a low-power-consumption dry-type transformer which comprises a dry-type transformer body, a supporting mechanism installed on the dry-type transformer body, an arc cleaning mechanism movably installed on the supporting mechanism and a wire clamping mechanism installed on the arc cleaning mechanism. The supporting mechanism comprises a bearing outer rail and a bearing inner rail located on the inner side of the bearing outer rail, and the arc cleaning mechanism comprises a base movably installed in a gap between the bearing outer rail and the bearing inner rail and a bottom-arranged base located on the top of the base. The two clamps are used for positioning and clamping a wire on the dry-type transformer, the multiple vertical rods located outside the two insulating shells can transmit an electric field and electric arcs around the dry-type transformer, and finally transmitted current can be conducted to the ground. Therefore, the lead on the dry-type transformer cannot be aged due to the sharp increase of the electric field intensity and the rising of the temperature.

This invention discloses a detachable hydroponic leek cultivation device for turtle ponds, belonging to the field of hydroponic devices. It includes several freely detachable and combinable floating boards, with detachable protective plates installed on the outer sides of the floating boards. The floating boards can be disassembled and reassembled, offering flexible use. The detachable protective plates at the outer edges of the floating boards prevent turtles from climbing in and eating the leeks. The leeks can absorb high levels of nitrogen, phosphorus, and other nutrients from the turtle farming water, removing eutrophic substances. The leek roots release oxalic acid and other organic acids, sulfides, and flavonoids, inhibiting pathogenic microorganisms in the aquatic environment and reducing the incidence of turtle diseases. This invention can not only be used for hydroponic leeks but also for cultivating other suitable hydroponic medicinal herbs and vegetables, and can be reused repeatedly.

This invention discloses a vibration-type respiratory sputum clearance device, relating to the field of medical device technology. It includes a vest body. Multiple independent liquid-coupled vibration units are arranged on the inner side of the vest, corresponding to the upper and lower lobes of both lungs and the projected lung region on the back. Each liquid-coupled vibration unit includes a sealed liquid-sealed bag, and a vibration unit is disposed on the outer side of each sealed liquid-sealed bag. The sealed liquid-sealed bag is integrally embedded and fixed in a flexible interlayer on the inner side of the vest. The interior of the sealed liquid-sealed bag is filled with a vibration-transmitting liquid. The vibration-transmitting liquid filled in the sealed liquid-sealed bag of this invention, relying on its incompressible and highly fluid physical properties, can efficiently transmit and convert the high-frequency micro-vibrations generated by the double-layer piezoelectric sheet, forming a dual mechanical action of shallow loosening and deep oscillation, perfectly adapting to the sputum clearance needs of the soft tissues of the chest and back and the deep airways of the thoracic cavity.
