Ultrahigh molecular weight polyethylene fiber composite bulletproof plugboard
ActiveCN224215962Ureduce weightreduce thicknessPersonal protection gearArmour platesFiberPolyethylene
The utility model discloses an ultra-high molecular weight polyethylene fiber composite bulletproof flashboard which comprises a protection assembly and a protection assembly wrapped in the protection assembly, the protection assembly comprises a wrapping cloth layer, and a plastic shell is wrapped in the wrapping cloth layer; the protection assembly comprises a metal bulletproof structure, a polyethylene structure is installed on one side of the metal bulletproof structure, a ceramic structure is installed on one side of the polyethylene structure, and the metal bulletproof structure, the polyethylene structure and the ceramic structure are wrapped in a plastic shell. The bulletproof plates made of three different materials are adopted, the thickness of the bulletproof steel plates is reduced, the weight of the steel plates can be effectively reduced, the weight of the device can be reduced again due to the fact that the middle layer is made of the polyethylene material, the ceramic plate is used in the innermost layer, small-caliber bullets cannot directly damage the ceramic plate, and through the combination of various structures, the bulletproof effect is good. And the bulletproof capability and the weight are balanced.

Submersible pump lifting mechanism
ActiveCN224215072UWeight increasebalance weightPump componentsGeneral water supply conservationGravity centerEnvironmental geology
The utility model provides a submersible pump lifting mechanism, which relates to the technical field of submersible pump lifting, and comprises a bottom plate, the upper surface of the bottom plate is fixedly connected with a support plate, the upper surface of the support plate is fixedly connected with a top plate, the lower surface of the bottom plate is provided with moving wheels, the bottom plate and the top plate are provided with square through grooves, and the bottom plate is slidably connected with a placing box. By arranging the placing box, when the submersible pump pumps water, the overall weight of the submersible pump is increased due to water pumping, then the gravity center of the device is changed, at the moment, the placing box is pushed to slide away from the supporting plate on the bottom plate, meanwhile, water pumped by the submersible pump is injected into the placing box, the weight of the placing box is increased, the gravity center is balanced, and the device is more stable.
