Problems solved by technology
[0003] Most of the traditional domestic fire extinguishing devices are centrifugal pumps or plunger pumps as the working principle of pressurization. Centrifugal pumps are characterized by low water pressure but large flow, and plunger pumps are characterized by high water pressure and small flow. Therefore The range is relatively small, it is difficult to meet the fire extinguishing requirements when high-rise buildings are on fire

The invention discloses a high-efficiency fire extinguishing device. The device comprises a power device, a crank connecting rod mechanism, a transmission device which transfers power of the power device to the crank connecting rod mechanism, a pressurization device and an operation device, wherein the crank connecting rod mechanism comprises a crank and a connecting rod, and the rotating shaft of the crank is connected with the transmission device; the pressurization device comprises a piston rod, a piston and a cylinder sleeve, one end of the piston rod is pivoted with the connecting rod, and the other end of the piston rod is connected with the piston, and the piston is arranged in the cylinder sleeve; the front end of the cylinder sleeve is connected with a pressure water pipe; a water inlet formed on the pressure water pipe and is connected with a water source, and the water inlet is provided with a water-intake check valve, and a water-outlet check valve is arranged in the pressure water pipe; and the operation device is a water gun interface arranged at the end of the pressure water pipe, and the water gun interface is connected with a water gun. The fire extinguishing device has long fire range, small size and convenience for use.
Description
Technical field [0001] The invention relates to a fire extinguishing device, in particular to a high-efficiency fire extinguishing water jet device. Background technique [0002] At present, due to the shortage of land resources and other reasons, there are many high-rise buildings in cities, and the high-rise fires of high-rise buildings in cities are often due to the high height. The general fire-fighting equipment has too small range to shoot fire water to a specific height to extinguish the fire. As a result, valuable rescue time is delayed, resulting in heavy losses of life and property, and even firefighters who have no choice but to approach the fire source for close firefighting will threaten their personal safety and die. High-rise building fires cause casualties every year. A typical case is the high-rise apartment fire on Jiaozhou Road, Yuyao Road, Shanghai on November 15, 2010, which killed 58 people and injured more than 70 people. Forest fire prevention and fire ex...
