[0101] refer to figure 1 , the present embodiment adopts the dual water source method of gravity water supply from the high-level gravity fire-fighting pool 110a and water supply from the fire-fighting water pump 120a from the transfer pipe network. The firefighting water pump 120a includes a firefighting water pump 121a and a firefighting water pump 122a connected in series.

[0102] Specifically, a low-level fire-fighting pool 230a and a fire-fighting water pump 121a are installed in the basement, a fire-fighting water pump 122a and an intermediate decompression water tank 130a are installed on the intermediate equipment floor, and a high-level gravity fire-fighting pool 110a and a pneumatic water tank 140a are installed on the roof. Because the lift of the first-stage fire-fighting water pump 121a is not enough, a second-stage fire-fighting water pump 122a is set between the first-stage fire-fighting water pump 121a and the intermediate decompression water tank 130a. When t...

[0105] refer to figure 2 , the present embodiment adopts the dual water source method of gravity water supply from the gravity fire-fighting pool 110c and water supply from the fire-fighting water pump 120c from the transfer pipe network. The firefighting water pump 120c includes a firefighting water pump 121c and a firefighting water pump 122c arranged in parallel. The gravity fire-fighting pool 110c includes a high-position gravity fire-fighting pool 111c set at a high position and an intermediate gravity pool 112c set at a middle position.

[0106] Specifically, a low-level fire-fighting pool 230c and fire-fighting water pumps 121c and 122c are installed in the basement, a high-level gravity fire-fighting pool 111c and a pneumatic water tank 140c are installed on the roof, and an intermediate gravity pool 112c is installed in the middle of the building. The fire-fighting water pump 121c supplies water to the water fire-extinguishing system 220c1 in the high area, and the ...

[0109] refer to image 3 , the present embodiment adopts the double water source mode of the gravity water supply of the high-level gravity fire-fighting pool 110d provided at the high position and the direct water supply of the fire-fighting water pump 120d.

[0110] Specifically, a low-level fire-fighting pool 230d and a fire-fighting water pump 120d are set in the basement, and a high-level gravity fire-fighting pool 110d and a pneumatic water tank 140d are set on the roof. The fire pump 120d supplies water to the water fire extinguishing system 220d, and the water source of the high-level gravity fire pool 110d on the roof comes from the domestic water supply source 210d.

[0111] Throughout the building, low areas are gravity fed and high areas are pressurized and gravity fed. Part of the high area is supplied with pressurized water by a pressurized pump on the roof, and part of it is supplied by the high-level gravity fire pool 110d on the roof, and a pressure reducing ...

Abstract

The invention discloses a super-high-rise building firefighting water supply device which is arranged on a super-high-rise building and supplies water for water fire extinguishing systems of the super-high-rise building, wherein the firefighting water supply device comprises gravity firefighting water tanks and a double-water-source firefighting water supply system which comprises low-position firefighting water tanks and firefighting water pumps. The gravity firefighting water tanks are arranged at the highest positions of the systems and supply water for the water fire extinguishing systemsin a gravity mode, and firefighting water tanks pump water from the low-position firefighting water tanks and supply water in a pressuring manner. The super-high-rise building firefighting water supply device supplies water by the aid of a double-water-source water supply mode. Compared with current domestic conventional engineering, devices such as a firefighting transmission pump and a middle water tank are decreased, the occupied area of a device machine room is decreased, cost is saved, and firefighting water supply reliability is greatly improved.

Description

technical field [0001] The invention belongs to the field of building fire protection engineering and water supply and drainage, and in particular relates to a super high-rise fire water supply device using dual water sources. The fire water supply system includes a fire water supply device and a water fire extinguishing system. Background technique [0002] According to incomplete statistics, there are 270,000 high-rise buildings in my country, about 90,000 public buildings and 180,000 residential buildings. There are 61 buildings in China. Moreover, the number of high-rise buildings in cities is still increasing, and my country has become the country with the most high-rise buildings in the world. [0003] High-rise buildings are a symbol of modern cities. With the continuous increase in building height, new challenges have been brought to building fire protection, especially super high-rise buildings, which have high investment, complex functions, and a large number of us...
