The folding top plate structure comprises a back plate, a top plate is rotationally installed on the back plate, a storage table is arranged at the upper end of the top plate, a lamp panel is arranged at the lower end of the top plate, first insertion holes are formed in the two sides of the back plate, and the first insertion holes are communicated with the storage table. The two sides of the top plate are provided with bolts which correspond to the first insertion holes in position and are fixedly inserted into the first insertion holes in a connected mode. According to the firewood stove, the top plate is horizontally arranged on the back plate, so that utensils such as a steamer and a food steamer can be conveniently placed on the storage table on the top plate, meanwhile, the utensils such as the steamer can be conveniently taken and used in the cooking process, the firewood stove is more convenient to use, the structure is more compact and reasonable, the size is greatly reduced, and the space is saved; and when the top plate is vertically rotated on the back plate, the top plate can avoid cooking of the firewood stove, so that steaming tools with relatively high stacking height can also meet cooking use, and the practicability of the firewood stove is better.

This disclosure provides a control circuit and electronic device for system overvoltage protection. The control circuit includes an overvoltage detection module, a fast charging interface module, and a system power module. One end of the overvoltage detection module is connected to the fast charging interface module, and the other end is connected to the system power module. The fast charging interface module is connected to the system power module. The overvoltage detection module is used to detect a first voltage input from the fast charging interface module to the system power module. When the detected first voltage is greater than a preset threshold, it sends a shutdown signal to the fast charging interface module to disconnect the line between the fast charging interface module and the system power module.

The application discloses a nitrogen-oxygen composite rare earth ceramic riser base and a preparation process thereof, and relates to the technical field of coke oven riser. The riser base comprises a base and a riser cylinder, the riser cylinder is fixedly arranged on the upper portion of the base, and the riser cylinder and the base are both circular in cross section and concentrically arranged. The base comprises the following components in parts by weight: 40-50 parts by weight of silicon carbide powder, 12-13 parts by weight of industrial silicon powder, 8-10 parts by weight of silicon micro powder, 2-3 parts by weight of additives and 33-36 parts by weight of a binding agent. A decoking assembly for cleaning graphite and tar attached to the inner wall of the base is arranged in the base. The preparation process comprises the following steps: S1, mixing; S2, forming; S3, sintering; and S4, installation. The application selects high-purity silicon carbide as the main raw material, guarantees excellent thermal shock stability of the product, adds rare earth oxides to improve the toughness of the riser base material, and further improves the wear resistance and oxidation resistance of the riser base.

This invention belongs to the field of fire-resistant composite material preparation technology, and provides a nano-aerogel ceramicized silicone rubber composite material, its preparation method, and fire-resistant cables. A silicon carbide layer is deposited on the surface of nano-silica aerogel using atomic layer deposition technology, enhancing the mechanical stability and high-temperature oxidation resistance of the aerogel. A silane coupling agent is used to chemically modify the aerogel surface, improving its interfacial compatibility. An Al-doped ceramicized precursor is prepared by reacting polynitrosilane with various functional silanes and metal compounds, enabling the material to form a dense ceramic protective layer at high temperatures. A phosphorus-containing silicon polymer is synthesized with DOPO as the core, further enhancing the flame-retardant properties of the material. By introducing the modified aerogel, Al-doped ceramicized precursor, and phosphorus-silicon polymer into phenyl silicone rubber and methylphenyl silicone resin, followed by vulcanization and ceramicization, a nano-aerogel / ceramized silicone rubber composite material is obtained for application in the field of fire-resistant cables.
