A self-closing residential fire hinge apparatus for closing a door during a fire includes a door hinge with a spring-actuated release mechanism. The spring-actuated release mechanism includes a spring that is pre-tensioned in an open position and a coating covering the spring. The coating is a solid material that retains the spring in the open position. The coating has a melting point less than a melting point of the spring. For example, the coating may be formed of bismuth. When the coating is heated and becomes malleable, the spring is released to a closed position. When the coating is solid and not malleable, the door hinge allows regular opening and closing of the door. The apparatus may also include a spring assembly cap, improving the aesthetics of the assembly. The spring assembly cap may be composed of copper, improving conduction of the ambient heat to melt the coating even faster.

When a fire occurrence mark arranged in a fire occurrence building is selected and operated, the hierarchy of the fire occurrence building is displayed and a fire occurrence floor is colored and displayed, and when the fire occurrence floor is selected and operated, the floor map of the fire occurrence floor is displayed and the fire occurrence mark is arranged in the fire occurrence section of the floor map.SELECTED DRAWING: Figure 1

An automatic dry horizontal sidewall fire protection sprinkler assembly for residential fire protection. The sprinkler assembly includes an elongate tubular outer housing having a first end and a second end. The second end of the housing defines an outlet opening and an internal channel and contact surface proximate the outlet opening. A fluid deflection member is coupled to the housing at a fixed distance from the outlet opening. An internal fluid control assembly includes an ejectable member that is ejected out the outlet opening and displaced out of the fluid flow path between the housing and the fluid deflection member. The sprinkler assembly provides a plurality of coverage areas suitable for residential fire protection over a plurality of nominal operating temperatures up to 200° F.

The invention relates to the technical field of smoke sensing alarm devices, in particular to a residence fire-fighting smoke sensing alarm device with a self-cleaning function, which comprises a mounting plate and an alarm body, and further comprises a U-shaped plate, a moving frame, a bristle plate, a through hole, a rack II and comb teeth, two connecting rods are arranged, one end of each connecting rod is fixedly connected with one side of the U-shaped plate, and the other end of each connecting rod is fixedly connected with the other side of the U-shaped plate; one ends of the two connecting rods are fixedly connected with the same push plate, and the push plate is connected to the inner wall of the moving frame in a matched and sliding mode. By arranging the comb tooth structure linked with the bristle plate, while the bristle plate cleans the smoke inlet hole of the alarm, the comb teeth automatically comb the bristles in a reciprocating manner, and dust accumulated on the bristles is removed in time. By means of the design, the problem that dust is pasted to the smoke inlet holes again due to saturation of bristles in a traditional device is solved, it is ensured that the cleaning effect is continuous and effective, and secondary pollution in the cleaning process is fundamentally prevented.

The invention relates to the technical field of fire equivalent combustion data processing, in particular to a standard comburent-based residential fire equivalent combustion method and system. The method comprises the following steps: constructing a standard comburent and a fire test platform, wherein the standard comburent is used for reproducing a fire test scene; the fire test platform is used for simulating a fire test; respectively inputting the standard comburent and the typical furniture into a fire test platform for testing, and measuring parameters such as heat release rate, total release heat, temperature and carbon dioxide release amount; respectively obtaining combustion data of the standard comburent and furniture combustion data; the combustion data of the standard comburent are compared with furniture combustion data, an equivalent combustion model is established, and equivalent substitution of the standard comburent to a furniture fire source is obtained; constructing an equivalent combustion model to equivalently replace typical furniture comburent; the system evaluates the feasibility of substitution in fire-fighting training, and provides a standardized, low-pollution and controllable comburent scheme for fire test and training scenes.

The application discloses a smart community security and protection management platform and method, relates to the technical field of community smart security and protection, and the management method is to acquire the monitoring video information of a community key intersection, community key road section patrolling information, collect and store vehicle and pedestrian access control access information, acquire residential fire and gas detection alarm information, and acquire intruder climbing community fence position information through system software in a screen display monitoring terminal of a monitoring platform; the acquisition of the intruder climbing community fence position information is carried out in a manner that a tension detection method is combined with an infrared detection method; the control system starts the infrared detection again according to the signal of the tension detection, so as to detect whether an intruder climbs on the side of the fence above the tension detection position, and further discriminates whether it is a system false alarm.

This invention discloses a fire rescue quick-rescue bag for residents that combines the functions of a carrying bag and a stretcher, relating to the field of fire rescue technology. It includes a main body, a carrying assembly, and an assembly assembly. When the quick-rescue bag needs to hold rescue items, the rotating support rod rotates, causing the mounting side plate to rotate from a horizontal to a vertical position. The lifting limit rod moves into the rotating limit groove, fixing the position of the rotating support rod. The connecting side plate rotates from a horizontal to a vertical position, and the supporting connecting rod moves and slides into contact with the rotating support rod. The connecting limit rod moves, fixing the supporting connecting rod to the rotating support rod. The connecting top plate moves to the top of the main body. The main body, mounting side plate, connecting side plate, and connecting top plate form a quick-rescue bag for storing items. Assembly and support are achieved through the rotating support rod and supporting connecting rod, while the lifting limit rod and connecting limit rod provide limiting and fixing, reducing assembly difficulty, increasing disassembly speed, and facilitating the use of the quick-rescue bag.

The invention relates to the technical field of fire hydrant water pressure adjustment, in particular to a rapid fire rescue water supply system for residential buildings. According to the system, through a data acquisition module, the fire hydrant water pressure of a floor between a fire floor and a top floor, the water pressure of a top floor tap water pipe and the water flow speed of a pipeline connected with a top floor fire hydrant and the top floor tap water pipe are acquired; then an opening amplitude acquisition module of the copper ball valve 1 and an opening amplitude acquisition module of the copper ball valve 2 analyze the data in the data acquisition module to acquire the opening amplitude of the copper ball valve 1 and the opening amplitude of the copper ball valve 2 at each moment until the opening amplitude of the copper ball valve 2 is greater than the opening amplitude of the copper ball valve 1; and stopping adjusting the opening amplitude of the copper ball valve 1 and the copper ball valve 2. According to the fire hydrant, the opening amplitude of the copper ball valve 1 and the copper ball valve 2 is adjusted in real time, so that the water pressure of the fire hydrant is rapidly increased, meanwhile, damage to a pipeline caused by too large water pressure of the fire hydrant is avoided, and the stability of fire extinguishing water supply is effectively improved.
