Problems solved by technology
[0005] However, since the high-pressure water mist fire extinguishing system requires relatively high water pressure, a powerful power source is usually required
In the fire scene, the power facilities are often destroyed by the fire, and the people trapped in the scene cannot obtain external power to extinguish the fire and save themselves

Embodiment Construction
[0019] The present invention will be described in detail below in conjunction with specific embodiments.
[0020] refer to figure 1 , a manual double-cylinder high-pressure single-phase flow fine water mist fire extinguishing device, including a connecting rod part, a double-cylinder part, and a walking part 5. The double-cylinder part realizes pressurization and eruption of the fire extinguishing medium (water); the connecting rod part amplifies and drives the human power Double-cylinder parts: By using the walking parts 5, the manual double-cylinder high-pressure single-phase flow fine water mist fire extinguishing device of the present invention can move freely.
[0021] The specific structure of the double cylinder parts is as follows: figure 2 As shown, it includes a piston 8, two parallel cylinders 1 (twin cylinders), a metal pipe 2, and a nozzle 3. The double cylinder is equipped with water inlet 7 and water outlet, the one-way valve is installed in the water inlet 7...

Description
technical field [0001] The invention relates to a manual double-cylinder high-pressure single-phase flow fine water mist fire extinguishing device, which belongs to the technical field of fire-fighting facilities. Background technique [0002] Since the 1970s, halon (also known as halon, translated as halon) has been widely used in fire extinguishers and fire extinguishing systems as a highly efficient and low-toxic gas fire extinguishing agent. Scientific research has found that halogenated alkanes have a strong destructive effect on the atmospheric ozone layer, which will seriously affect the ecological environment and human health, which has aroused great concern from the international community. In March 1985, the United Nations Environment Program held the Ozone Layer Protection Conference in Vienna, Austria, and passed the "Vienna Convention for the Protection of the Ozone Layer". In September 1987, all countries in the world jointly signed the "Montreal Protocol" in M...
