This invention relates to a flame-retardant sprayable polyurea waterproof coating for rigid foam roofing insulation. The coating comprises component A and component B. Component A includes a modified isocyanate prepolymer. Component B includes the following components: polyether, amino chain extender, amino POSS crosslinking agent, expanded graphite flame retardant, and additives. The modified isocyanate prepolymer is obtained by reacting amino POSS, polyether polyol, and MDI. Through the compounding of component A and component B, this invention reveals that the modified isocyanate prepolymer containing a POSS cage structure, the amino POSS crosslinking agent, and the expanded graphite flame retardant synergistically and significantly improves the flame-retardant and heat-resistant properties of the coating, while also enhancing the material's hardness and adhesion, among other physical and chemical properties.

This application provides a flight device, comprising: a fuselage; and an energy storage component disposed outside the fuselage, the energy storage component including a connecting mechanism and a battery, the connecting mechanism being mounted on the fuselage; the connecting mechanism having a locked state and an unlocked state, the connecting mechanism being configured to switch between the locked state and the unlocked state, in the locked state the connecting mechanism being connected to the battery, and in the unlocked state the connecting mechanism being disengaged from the battery, thereby detaching the battery from the fuselage. With this configuration, in emergency situations such as battery spontaneous combustion, the connecting mechanism can switch to the unlocked state. Since both the connecting mechanism and the battery are located outside the fuselage, the interior of the fuselage can be effectively isolated from fire sources, while the battery can be quickly jettisoned.

This patent introduces a power distribution switch control cabinet capable of preventing and protecting against fires, facilitating timely response to any fires that may occur. This structure is named a fireproof power distribution switch control cabinet. In this fireproof power distribution switch control cabinet, several cooling fans dissipate high internal temperatures through several cooling grids, preventing heat accumulation and the generation of a fire. When the smoke sensor and the fire detection device detect smoke and open flames, they activate several exhaust fans at the top and the high-pressure powder storage box at the bottom, extinguishing the open flames inside through the powder spraying pipe and several powder spraying holes. Simultaneously, the exhaust fans reverse to create negative pressure inside, discharging the smoke through the exhaust stack.

This utility model discloses an explosion-proof and flame-retardant liquid-cooled high-voltage automotive cable and its cable sheathing equipment. The cable includes a liquid-cooling pipe, a bare copper conductor, a wrapping layer, an explosion-proof tin-plated braided copper mesh, and a polyolefin insulation layer; the liquid-cooling pipe is located in the center of the cable. The cable sheathing equipment is a screw extruder, and the extrusion die is a double-layer die, including an inner die tube and an outer die tube. This utility model can effectively improve the cooling efficiency of the cable by setting up the liquid-cooling pipe, reducing the risk of fire caused by cable overload during the operation of electric vehicles, and improving the safety of electric vehicle operation. The cable sheathing equipment provided by this utility model, through the setting of the double-layer extrusion die, can effectively reduce the risk of compression deformation of the liquid-cooling pipe during the extrusion operation, ensuring the cooling efficiency of the cable.

The present application relates to the technical field of forest cultivation, and provides a large-diameter-grade knot-free fine timber cultivation method for pine-broadleaf mixed forest, which comprises the following steps: selecting a forestation site and then carrying out site preparation, planting pine seedlings and broadleaf tree species, pruning according to a pine branch stake embedding area formula, applying an external growth agent to the pruning mouth, thinning and adjusting the pine forest density, and harvesting the pine when it is matured. The pine and broadleaf tree species are planted and mixed at the same time, which can promote the growth of the pine, improve the soil environment, enhance the resistance to the outside world, and significantly improve the comprehensive benefits per unit area. In addition, after pruning and applying the external growth agent, the cultivation period of the knot-free pine fine timber is shorter.

This utility model discloses a portable support for fixing fireworks arrays during launch, relating to the field of fireworks technology. It includes a bottom support at the bottom of the fireworks array, with symmetrical side support members that mate with the outer surface of the fireworks array. Two side support members are connected by fasteners to form a launch support for clamping the fireworks array. The bottom support includes an outer frame with a rectangular structure. A crossbar is symmetrically fixed to the top of the outer frame, and the bottom of each side support member is connected to the crossbar. This utility model, through the bottom support and side support members forming a support structure, effectively resists the recoil force during fireworks launch, preventing tipping and reducing the risk of fire or personal injury. The folding design significantly reduces storage volume, and the straps also serve as fixing tools, facilitating transportation and storage. The Velcro closure combined with the straps allows for simple operation, enabling quick assembly or disassembly without tools.
