Description

Technical Field

[0001] The present invention relates to the technical field of automatic fire fighting systems, and in particular to an automatic fire fighting system for high-rise buildings and a device thereof. Background Art

[0002] With the acceleration of urbanization, the number of high-rise buildings continues to increase. However, high-rise building fires are characterized by rapid spread, difficult evacuation, and significant challenges in firefighting. Traditional firefighting models suffer from limitations such as delayed response and low firefighting efficiency in the initial stages of fires, making them unable to meet the growing demand for fire safety. Therefore, the development of an efficient and intelligent high-rise building firefighting system is urgent.

[0003] After searching, the application proposal of Chinese patent application number CN202323425685.8 discloses a building fire safety intelligent monitoring system, which includes a building fire server and floor fire monitoring equipment located on different floors of the building. Each floor fire monitoring equipment is connected to the building fire server through a network and communicates with the building fire server. The system also includes multiple area monitoring cameras and multiple area fire water tanks arranged at different positions on each floor of the building. Each area fire water tank is connected to the water supply pipe of the building. Each area monitoring camera is connected to the corresponding floor fire monitoring equipment for monitoring the area. The system also includes multiple fire extinguishing hoses corresponding to the area fire water tanks. The building fire safety intelligent monitoring system in the above-mentioned document has the following deficiencies: although it has the function of intelligent fire extinguishing, it is not intelligent enough and does not have the functions of guiding escape, providing temporary protection, etc., and needs to be improved. In addition, the following deficiencies exist in the prior art: 1. Traditional high-rise building fire protection systems rely on a single fire water pool or high-level water tank for water supply. Once the pool or water tank fails, the fire water supply to the entire building will be interrupted; 2. Traditional firefighting systems require large-capacity fire water tanks on rooftops or basements, which take up a lot of space. In high-rise buildings, fire pumps need to run for a long time in the event of a fire, which consumes a lot of energy. In addition, large-capacity fire water tanks put a lot of pressure on the weight of a single floor of the building. 3. In traditional fire-fighting equipment, when a fire occurs, it is necessary to wait for the fire pump to start and deliver water to the fire floor, which will delay the fire-fighting opportunity. In addition, delayed water pump start-up or insufficient municipal water supply pressure will cause unstable water pressure, thereby affecting the efficiency of fire-fighting.

In addition, the water source of the fire extinguishing device is installed on each floor, and the water source is on the same floor or adjacent to the fire source, which reduces the pipeline delay of the traditional fire-fighting device's remote water supply.

[0024] The present invention has a high efficiency in water replenishment.

The two share the same piping system, and the water supply and drainage main pipelines are reused, reducing redundant pipelines and the need for opening holes in the building structure. In addition, the surplus water in the daily storage chamber can be temporarily supplemented to the fire-fighting chamber through a valve, which increases the efficiency of dynamic allocation of water resources.

A slope 10 is provided inside the overflow water tank 3 to concentrate the water, and then transport it to the inside of the drain pipe 8 through the anti-backflow pipe 106 installed through it. By controlling the drain port 105, the water inside the fire water tank 2 can be quickly discharged, which can be used to supplement the fire water in the lower water tank.

[0047] like Figure 9 As shown, the water conveying mechanism includes an upper branch pipe 104 fixedly installed at the output end of the first water delivery pump 101, the upper branch pipe 104 runs through the fire water tank 2, and a pressure water pump 102 is fixedly installed on the left outer surface of the fire water tank 2 at the upper end of the upper branch pipe 104, the upper branch pipe 104 is fixedly installed at the lower end of the pressure water pump 102, and an upper pipe 103 is fixedly installed on the upper end of the pressure water pump 102, and an inlet elbow 107 is fixedly installed on the upper end of the upper pipe 103, and the upper end of the inlet elbow 107 is fixedly installed on the left surface of the fire water tank 2. When the fire water in the superstructure is insufficient, the first water delivery pump 101 and the pressure water pump 102 transport the fire water inside the fire water tank 2 upward, so as to quickly replenish the fire water.

[0048] Working principle: Under normal conditions, the daily water tank 1 and the fire water tank 2 are independent of each other and do not interfere with each other. People use the water inside the daily water tank 1 through the water pipe 4. At this time, the water level of the fire water inside the fire water tank 2 is at a fixed height, and the overflow tank 3 is empty.

[0049] When a fire occurs on this floor, the second water delivery pump 301, fixed at the lower end of the fire water tank 2, delivers fire water to the diversion pipe 303. Through the diversion pipe 303, the rotating sprinkler mechanism performs the fire extinguishing operation. At this time, the pressurized water flows rapidly into the sprinkler pipe 305. The turbine 307 inside the sprinkler pipe 305 is driven by the fast-flowing water flow, causing the rotating ring 308 mounted on one side to rotate. This, in turn, drives the rotating nozzle 310 at the lower end to rotate through the meshing external gear disc 311. The rotating nozzle 310 is driven by the water to rotate, expanding the spray angle and fire extinguishing area, avoiding blind spots in the firefighting and increasing the fire. The staff controls the water diversion branch pipe 9 to deliver daily water from the daily water tank 1 to the fire water tank 2, avoiding water shortages that delay firefighting.

[0050] After the fire extinguishing operation is completed, the water inside the fire water tank 2 is lower than the normal water level. The float 205 in the water replenishment mechanism is pulled downward by gravity, dragging the connecting rod 210 outward. The valve core 207, which is slidably mounted inside the valve body 206, is driven by the connecting rod 210 to open the passage at the upper end of the water inlet branch 203. Fire water from the municipal water pipe enters the fire water tank 2 from the water inlet pipe 201 through the water inlet branch 203. When the fire water reaches the specified water level, the float 205 is pressed by the buoyancy of the connecting rod 210. The connecting rod 210 and the spring 209 push the valve core 207 to the right side of the water inlet branch 203, thus sealing the water inlet branch 203. If the water level inside the fire water tank 2 is too high, the excess fire water flows through the overflow pipe 108 into the overflow tank 3 below, controlling the maximum water level inside the fire water tank 2 and preventing water from overflowing from the top of the fire water tank 2, which may damage the equipment or even cause a short circuit.

[0051] When the fire-fighting water supply on the lower floor is insufficient, the fire-fighting water tank 2 on this floor needs to be replenished. The operator controls the drain port 105 to open the channel between the drain pipe 8 and the fire-fighting water tank 2, so that the fire-fighting water inside the fire-fighting water tank 2 on this floor is quickly transported to the daily water tank 1 on the lower floor, and then controls the water diversion branch pipe 9 for secondary transportation, so as to quickly replenish the fire-fighting water on this floor to the fire-fighting water tank 2 on the lower floor. The internal structure of the fire-fighting water tank 2 is designed so that a fixed amount of basic water is retained inside the fire-fighting water tank 2 on this floor, avoiding the situation where the fire-fighting water is completely emptied.

[0052] When there is insufficient fire-fighting water on the upper floors, the first water delivery pump 101 fixedly installed at a high position inside the fire water tank 2 is activated. The first water delivery pump 101 starts working to transport the fire-fighting water inside the fire water tank 2 to the outside through the upper branch pipe 104. Since the distance between high-rise buildings is large, the fire-fighting water needs to be pressurized for the second time. The pressure water pump 102 fixedly installed on the outside of the fire water tank 2 pressurizes the fire-fighting water for the second time and transports it to the upper pipe 103 at the upper end. The upper pipe 103 is connected to the lower end of the water inlet elbow 107, and the two are connected to transport the fire-fighting water at the lower end to the inside of the fire water tank 2 on the upper floor. The water inlet elbow 107 and the water inlet pipe 201 are located in the fire water tank 2 at a position higher than the upper end of the overflow pipe 108 to prevent the water inside the fire water tank 2 from flowing back and causing secondary pollution.
