Description

Wind power fire extinguishing device with enhanced fire extinguishing function

Technical Field

The utility model relates to a wind power fire extinguishing device with enhanced fire extinguishing function.

Background

The wind fire extinguisher, commonly known as a blower, is mainly applied to forest fire extinguishing, fire fighting and emergency treatment, landscaping, highway engineering and the like, and is also used for industrial production. The wind power fire extinguisher blows a large stream of air to flame at high speed, so that the surface temperature of a burning object is rapidly reduced, and when the temperature is lower than the ignition point, the burning is stopped. The blower drives the wind wheel to generate high-speed airflow through the gasoline engine so as to blow out flame and sundries. The wind fire extinguisher is suitable for fighting fire disasters of young forests or secondary forests, grassland fire disasters and fire disasters of barren mountains and grass slopes. The wind fire extinguisher has little single fire extinguishing function, and can obtain better effect by matching two machines or three machines. In some cases, the use of a pneumatic fire extinguisher is not suitable: (1) a fire having a flame height of more than 2.5 meters; (2) the height of the shrub is more than 1.5 m, and the height of the grass plant exceeds 1 m. The reason is that when the height of the grass irrigation exceeds 1 m, the grass irrigation is extremely flammable and quickly spread once on fire due to unclear sight, and people cannot evacuate timely to extinguish fire, so that people are easily injured. (3) The height of the flame exceeds 1.5 m; (4) a great amount of fallen trees and disordered objects exist in the forest; (5) the wind fire extinguisher can only extinguish open fire but not blind fire. To sum up, the wind fire extinguisher has its limitation of putting out a fire, and the efficiency of putting out a fire is also not high, can bring certain safety risk for the fire fighter simultaneously.

Detailed Description

The invention is described in further detail below with reference to the accompanying drawings:

as shown in figure 1, this patent provides a wind-force extinguishing device of enhancement mode fire extinguishing function that wind-force was put out a fire and superfine dry powder 3 was put out a fire, it is on backpack wind-force fire extinguisher basis to creatively increase the function that sprays superfine dry powder 3, can not only carry out the wind-force and put out a fire, can spray superfine dry powder 3 again and carry out high efficiency and put out a fire, and the device has improved the fire extinguishing efficiency of fire extinguisher, has increased the safety protection to the user. When a fire disaster occurs, the fire extinguisher device is converted into the function of spraying the superfine dry powder 3 so as to achieve the purpose of high-efficiency fire extinguishing, and meanwhile, when firefighters evacuate from the fire scene, the superfine dry powder 3 can be used for fire extinguishing of an evacuation channel, so that the personal safety protection is greatly improved. The superfine dry powder 3 is the fire extinguishing agent with the highest fire extinguishing efficiency in the existing known fire extinguishing agents, the average particle size of 90% is smaller than 20 micrometers, the fire extinguishing concentration can reach 50g/m, and after the superfine dry powder 3 is sprayed out by means of high-speed gas, the high-efficiency fire extinguishing effect can be achieved, and the superfine dry powder can be suspended in the air for a certain time.

Specifically including backpack wind-force fire extinguishing host computer 1, 1 tops of backpack wind-force fire extinguishing host computer are provided with dry powder case 2, the intussuseption of dry powder case 2 is filled with superfine dry powder 3, backpack wind-force fire extinguishing host computer 1 is connected with main tuber pipe, main tuber pipe end is to having docked dryer 8, dry powder case 2 is connected with air inlet hose 6 and air-out hose 12, air inlet hose 6 is terminal to be linked together with main tuber pipe through the three-way valve 13 of taking the handle, air-out hose 12 is terminal to be linked together with dryer 8.

An air inlet joint 4 is arranged on the upper portion of the dry powder box 2, an air outlet joint 16 is arranged on the lower portion of the dry powder box 2, the pipe orifice of the air inlet hose 6 is butted on the air inlet joint 4 and fixed through a hoop 5, the pipe orifice of the air outlet hose 12 is butted on the air outlet joint 16 and fixed through the hoop 5, and the caliber of the air inlet joint 4 is larger than that of the air outlet joint 16. The tail end of the air outlet hose 12 is connected with a hard bent pipe 10 and is close to the outer side of the air duct 8, and the tail end of the hard bent pipe 10 extends into the air duct 8. In order to facilitate powder spraying, the tail end of the hard bent pipe 10 is connected with a powder spraying pipe 9. The tail end of the air inlet hose 6 is connected with a right-angle elbow 14, and the right-angle elbow 14 is connected with a three-way valve 13. The air outlet hose 12 is provided with a ball valve 11, and the middle section of the main air outlet pipe is provided with a corrugated pipe 15. The main air outlet pipe is provided with a handle 7.

The specific working principle is as follows: when the wind power fire extinguishing function is used, when the handle of the three-way valve 13 rotates to the position a, wind generated by the backpack fire extinguishing main machine reaches the three-way valve 13 through the main wind outlet pipe, at the moment, the three-way valve 13 is straight, and the outlet on the side surface is not straight, so the wind passes through the three-way valve 13 and then is blown out through the wind barrel 8, and fire extinguishing or other purposes are realized. When the superfine dry powder 3 is used for fire extinguishing, when the handle of the three-way valve 13 rotates to the position b, the ball valve 11 is opened at the same time, the wind generated by the backpack fire extinguishing host reaches the three-way valve 13 through the main wind outlet pipe, at the moment, the three-way valve 13 is laterally communicated, and the direct outlet is not communicated, so that the wind enters the dry powder tank 2 through the right-angle elbow 14, the inlet hose and the inlet connector 4 in sequence after passing through the side outlet of the three-way valve 13, certain wind pressure is generated, and the wind power drives the dry powder to be sprayed out through the wind duct 8 after passing through the wind outlet connector 16, the wind outlet hose 12, the ball valve 11 and the hard bent pipe 10, thereby efficiently extinguishing fire. When the dry powder box is designed, the caliber of the air inlet pipeline is large, the caliber of the air outlet pipeline is small, and meanwhile, the dry powder box 2 is subjected to sealing treatment, so that certain air pressure can be generated inside, dry powder is driven to be sprayed out at a certain air speed, and the air speed depends on the air pressure generated by the fire extinguishing host machine.

The foregoing is only a preferred embodiment of this patent, and it should be noted that, for those skilled in the art, various modifications and substitutions can be made without departing from the technical principle of this patent, and these modifications and substitutions should also be regarded as the protection scope of this patent.
