The invention relates to an integral type blasting operation safety protective cover. The integral type blasting operation safety protective cover comprises a periphery structure, a cover plate, a hole opening cover plate, protective bars and hoisting rings of the safety protective cover; the periphery structure is composed of two longitudinal steel plates and two transverse steel plates; upper strengthening ribs and lower strengthening ribs are arranged on the periphery of the outer side of the periphery structure; a plurality of internal tie bars and internal strengthening ribs which are transversely and longitudinally crossed are arranged inside the periphery structure; the cover plate is arranged above the periphery structure and is connected with the longitudinal steel plates to enable the longitudinal steel plates and the periphery structure to form a whole; a cover plate exhaust hole is formed in the middle portion of the cover plate; the protective bars are arranged on the cover plate; the hole opening cover plate is placed between the cover plate and the protective bars and covers the cover plate exhaust hole; and the hoisting rings are arranged on the longitudinal steel plates. According to the integral type blasting operation safety protective cover, on the premise that the blasting speed of blasting operation on hard rock is guaranteed, safety of the blasting operation can be guaranteed, meanwhile, noise generated by the blasting operation is weakened, and the very good economical benefits and social benefits are achieved.

The invention belongs to the technical field of batteries and particularly relates to a silicon-based negative electrode material for lithium ion batteries. Based on the total mass of the silicon-based negative electrode material being 100%, the silicon-based negative electrode material includes the following components in mass percentages: 90% to 99.3% of silicon-based functional material, 0% to5% of carbon black conductive agent, 0.1% to 5% of carbon nanotube conductive agent, 0.5 to 5% of binder, and 0.1% to 2% of thickener, with the balance of water, wherein the carbon nanotube conductiveagent coats the surface of the silicon-based functional material. A grid-shaped winding structure formed on the surface of the carbon nanotube silicon-based functional material having a chain structure in the silicon-based negative electrode material for lithium ion batteries can have a good electrically conductive effect, effectively enhances the conductivity of the silicon-based negative electrode material, can suppress the volume change and expansion of the silicon-based functional material during the intercalation / delithiation process, prolongs a battery life, and improves the safety performance of the battery.

The invention belongs to the technical field of household appliance transportation, and particularly relates to a loading and unloading device for household refrigerator transportation. The problem that a carrying device in the prior art is mostly lifted by a forklift and has large site limitation is solved. According to the scheme, the loading and unloading device comprises a base, universal wheels are fixed to the positions, close to the four corners, of the lower surface of the base through bolts, two sets of C-shaped steel stand columns are fixed to the positions, close to the four corners, of the upper surface of the base, openings of the two C-shaped steel stand columns in each set are opposite and parallel to each other, and sliding blocks are slidably connected to the interiors ofthe two C-shaped steel stand columns in each set. When a refrigerator body needs to be loaded and unloaded in use, the four corners of the bottom of the refrigerator body only need to be fixed throughpull ropes, then the pull ropes are wound around a belt wheel at the top end, then the four pull ropes are pulled at the same time, and the refrigerator body can be slowly lifted; and when the refrigerator is lifted, the four C-shaped steel stand columns can enclose the refrigerator, the protection effect is achieved, and the lifting safety is improved.
