Description

Technical Field

[0001] The invention relates to the technical field of fire-fighting equipment, and in particular to a capsule-type fire-extinguishing device. Background Art

[0002] The capsule-type fire extinguishing device of the prior art can spray foam on the protected area where the fire occurs when extinguishing a fire. The foam forms a foam covering layer to isolate the surface of the burning object from the air, thereby playing the role of suffocating the fire. In addition, the moisture washed out by the foam will also cool the surface of the burning object. The water vapor generated by the evaporation of the foam due to heat can reduce the oxygen concentration near the burning object. Therefore, the capsule-type fire extinguishing device has become a fire extinguishing device commonly used in the world today.

[0003] The existing capsule-type fire extinguishing device has a relatively complex overall structure and low sensitivity. When a fire occurs, it is difficult to send out an alarm signal in time, and the fire extinguishing foam liquid inside the capsule cannot be squeezed out to produce foam to cover the surface of the burning object, which brings great inconvenience to the fire extinguishing work in the protection area; in addition, during the fire extinguishing process, the current capsule-type fire extinguishing device is difficult to spray the generated foam evenly into the protection area where the fire occurs, and the fire extinguishing effect is poor, which brings great harm to people's life safety.

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below with reference to specific diagrams.

[0021] Reference Figure 1 As shown, a capsule-type fire extinguishing device is shown, including a protection area 100, a pressure tank 200, a proportioning mixer 1200, a water source storage tank 400, a foam liquid storage tank 500, a smoke detector, a temperature detector and a fire alarm controller.

[0022] Fire monitoring and protection is required in the protection area 100. A fire extinguishing pipe 110 is laid along the top of the protection area 100. The fire extinguishing pipe 110 is provided with a plurality of foam injection holes spaced along its distribution direction, and a foam injection nozzle 111 is provided on the foam injection hole.

[0023] A capsule body 300 for containing foam liquid is arranged in the pressure tank body 200. The capsule body 300 has excellent elasticity and can contain a large amount of foam liquid, thus bringing great convenience to the subsequent fire extinguishing in the protection area.

[0024] The proportioning mixer 1200 can mix water and foam liquid in a set proportion. The water outlet on the high-pressure side of the proportioning mixer is connected to the water inlet of the pressure tank body 200 through the first pipe 700, and a first valve body 710 is provided on the first pipe 700. The liquid inlet on the low-pressure side of the proportioning mixer 1200 is connected to the liquid outlet of the capsule body 300 through the second pipe 800, and a second valve body 810 is provided on the second pipe 800. The liquid outlet on the low-pressure side of the proportioning mixer 1200 is connected to the fire extinguishing pipe 110 through the conveying pipe 900, and a foam generator 910 for mixing water and foam liquid in proportion to produce foam is provided on the conveying pipe 900.

[0025] The water source holding pool 400 is used to hold water used for fire extinguishing. The water in the water source holding pool 400 is connected to the water inlet on the high-pressure side of the proportioning mixer 1200 through the third pipe 600. The third pipe 600 is provided with a first power pump 610 for transporting the water in the water source holding pool to the proportioning mixer.

[0026] The foam liquid storage tank 500 is used to store the foam liquid for fire extinguishing. The foam liquid in the foam liquid storage tank 500 is connected to the liquid inlet of the capsule body 300 through the fourth pipe 1000. A second power pump 1010 is provided on the fourth pipe 100 for transporting the foam liquid in the foam liquid storage tank 500 to the capsule body 300. A third valve body 1020 is provided on the fourth pipe 1000 near the liquid inlet of the capsule body 300.

[0027] The smoke detector is used to monitor the smoke concentration in the protection area in real time. The smoke detector is set on the top inside the protection area. The temperature detector is used to monitor the temperature value in the protection area in real time. The temperature detector is set on the top inside the protection area. Through the effective combination of the smoke detector and the temperature detector, the fire monitoring sensitivity of the capsule fire extinguishing device is effectively improved, further ensuring the safety of life and property.

[0028] When a fire occurs in the corresponding protection zone, the fire alarm controller can promptly control the corresponding valve body and power pump to open and can squeeze out the foam liquid in the capsule body and mix it with water in a set ratio. The foam generated by the foam generator is then sprayed into the protection zone through the foam spray nozzle. The fire alarm controller is respectively connected to the smoke detector, the temperature detector and the first valve body 710, the second valve body 810, the third valve body 1020, the first power pump 610 and the second power pump 1020 for communication.

[0029] The water outlet of the pressure tank body 200 is connected to the water source holding tank 400 through a return pipe 1100. A third power pump 1110 is provided on the return pipe 400 for transporting the water flowing into the pressure tank body 200 to the water source holding tank 400. A fourth valve body 1120 is provided at one end of the return pipe 1100 close to the water outlet of the pressure tank body 200. The third power pump 1110 and the fourth valve body 1020 are respectively connected to the fire alarm controller for communication.

[0030] A one-way valve 820 is provided at one end of the second pipe 800 near the liquid outlet of the capsule body 300. This structure can effectively prevent the foam liquid flowing out of the capsule body from flowing back into the capsule body, thereby effectively improving the practical performance of the capsule-type fire extinguishing device.

[0031] The working principle of the present invention is as follows:

[0032] When a fire occurs, the smoke detector sounds an alarm, the fire alarm controller sends a fire alarm signal, and at the same time, the sound and light alarm inside the protection area is activated to send an alarm signal to remind people on site to evacuate the fire scene. The fire temperature continues to rise, the temperature detector sounds an alarm, the fire alarm controller confirms the fire alarm signal, and the fire alarm controller controls the first power pump to work, and at the same time controls the first valve body and the second valve body to open.

[0033] When the pressurized water enters the proportioning mixer, most of the water passes through the orifice plate of the proportioning mixer and enters the low-pressure area of ​​the rear section, and a small amount of water enters the pressure tank through the first valve body. The water flowing into the pressure tank squeezes the capsule body, so that the foam liquid in the capsule body enters the low-pressure area of ​​the proportioning mixer through the second valve body under the pressure. In the low-pressure area, the water and the foam liquid are automatically mixed in proportion to form a foam mixture, which is sent to the foam generator through a conveying pipeline. The mixture coming out of the foam generator becomes air foam, and the air foam finally covers the surface of the burning object through the foam injection nozzle to extinguish the fire.

[0034] When the flow rate of the liquid outlet of the capsule body is uniform, within the set time, the fire alarm controller controls the third valve body and the fourth valve body to open, and controls the second power pump and the third power pump to work synchronously, so that the amount of water flowing out of the pressure tank body and the amount of foam liquid flowing into the capsule body reach a dynamic balance until the fire source in the protection area is completely extinguished. This structure prevents the foam liquid contained in the capsule body from being insufficient to extinguish the fire source in the protection area, effectively improving the practical performance of the capsule-type fire extinguishing device.

[0035] In summary, the present invention adopts the above-mentioned structure to make its overall structure relatively simple and highly sensitive. When a fire occurs, it can send out an alarm signal in time, and can evenly spray the fire-extinguishing foam into the protection area where the fire occurs, with good fire-extinguishing effect, which brings great convenience to the fire monitoring and fire-fighting work in the protection area.

[0036] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
