Technical Field
[0001] This utility model belongs to the technical field of fire-fighting water supply equipment, and in particular relates to a redundant booster integrated device for fire-fighting water supply. Background Technology
[0002] Fire water supply refers to the system or facility that provides water source and pressure to meet the fire fighting needs such as fire extinguishing, fire control, cooling, and smoke exhaust during fire fighting. It is one of the core components of the building fire protection system. Its main function is to ensure that sufficient water volume and pressure can be delivered quickly and effectively when a fire occurs in order to control the spread of fire, extinguish the fire, and protect the lives and property of people.
[0003] In fire-fighting water supply systems, a single water pump serves as the power source. When the pump experiences malfunctions such as motor burnout, impeller wear, or mechanical seal leakage, the fire-fighting system will be paralyzed and unable to supply water in a timely manner. Furthermore, the fire-fighting system relies on the water pump for direct pressurization. When multiple floors simultaneously activate fire hydrants or sprinkler systems, the pipeline pressure drops sharply, resulting in insufficient water output from the end-point fire-fighting equipment. At the same time, the standby pump is often in a shutdown state, making it prone to water accumulation and corrosion. Therefore, a redundant pressurization integrated device for fire-fighting water supply is needed. This device uses air compression combined with a pressurization tank to replenish and pressurize the water, ensuring stable water pressure. It also employs a dual-redundant integrated water supply design to ensure water supply stability in emergency situations. Utility Model Content

[0026] Figure 1-5 This invention illustrates an embodiment of a redundant booster integrated fire-fighting water supply device, comprising a main water pump 1; a standby water pump 2 is located to the right of the main water pump 1; the inlet of the main water pump 1 is connected to a main water pipe 3; the inlet of the standby water pump 2 is connected to a standby water pipe 4; an air compressor 7 is located to the left of the main water pump 1; a booster tank 8 is located to the left of the air compressor 7; a drain assembly 9 is located at the bottom of the standby water pump 2; a connecting pipe section 10 is connected to the outlet of the main water pump 1; a third gate valve 11 is fixedly installed at the top of the connecting pipe section 10; a water supply pipe 12 is connected to the rear side of the connecting pipe section 10; a booster pipe 13 is connected to the rear side of the bottom of the booster tank 8; and the booster pipe 13 is located away from the booster tank 8. One end of the booster pipe 13 is connected to the connecting pipe section 10. A solenoid valve is installed at the end of the booster pipe 13 near the connecting pipe section 10. A fourth gate valve 14 is fixedly installed on the rear side of the top of the water supply pipe 12. A pressure sensor 15 is fixedly installed on the rear side of the surface of the water supply pipe 12. The detection end of the pressure sensor 15 extends into the inner cavity of the water supply pipe 12. The outlet end of the standby water pump 2 is connected to a connecting pipe 16. The end of the connecting pipe 16 away from the standby water pump 2 is connected to the third gate valve 11. A PLC control cabinet 17 is installed on the rear side of the air compressor 7. The PLC control cabinet 17 is electrically connected to the main water pump 1 and the standby water pump 2 through the water pump controller. The pressure sensor 15 is electrically connected to the PLC control cabinet 17.
[0027] The above scheme is adopted: by using the main water pump 1, main water pipe 3, air compressor 7 and booster water tank 8 together, the fire water is pressurized and transported. At the same time, with the cooperation of the main water pipe 3, backup water pipe 4 and connecting pipe 16, water supply is uninterrupted after the main water pump 1 fails, thereby ensuring the stability of water pressure and continuous water supply.
[0028] refer to Figure 1 , 2 4. A first gate valve 5 is fixedly installed on the top of the main water pump 1, a second gate valve 6 is fixedly installed on the top of the main water pipe 3, the air outlet of the air compressor 7 is connected through an air pipe, and a pressure relief valve is fixedly installed on the top of the booster water tank 8.
[0029] The above scheme is adopted: by using the first gate valve 5 and the second gate valve 6 together, the water supply status of the backup water pipe 4 and the main water pipe 3 are controlled respectively. With the cooperation of the air compressor 7 and the booster water tank 8, the water pressure is boosted.
[0030] refer to Figure 3 , 4 5. The drain assembly 9 includes a drain pipe 91 fixedly connected to the bottom of the standby water pump 2. The drain pipe 91 is connected to the inner cavity of the standby water pump 2. A fixing bracket 92 is fixedly connected to the surface of the drain pipe 91. A drain sleeve 93 is slidably connected to the inner cavity of the drain pipe 91. Multiple drain holes 94 are circumferentially opened on the surface of the drain sleeve 93. The drain holes 94 are connected to the inner cavity of the drain pipe 91. A stepper motor 95 is fixedly installed at the bottom of the fixing bracket 92.

The top of the sealing ring 98 is in close contact with the bottom of the drain pipe 91.
[0031] The above solution is adopted: by setting up the drain assembly 9, the stepper motor 95 drives the drain sleeve 93 vertically and raises it with the cooperation of the threaded rod 97 and the threaded pipe 96, and controls the drain hole 94 to enter and exit the inner cavity of the drain pipe 91, thereby draining the water accumulated in the inner cavity of the standby water pump 2.
[0032] Working Principle: When using this utility model, the user turns on the main water pump 1. The main water pump 1 draws water from the main water pipe 3 and supplies fire-fighting water through the connecting pipe section 10 and the water supply pipe 12. When the water reaches the rear end of the water supply pipe 12, the pressure sensor 15 detects the water pressure inside the water supply pipe 12. When the water pressure is greater than the set value, the solenoid valve on the surface of the booster pipe 13 opens and delivers water to the inner cavity of the booster tank 8, causing the water pressure inside the water supply pipe 12 to drop to the set value. When the water pressure is less than the set value, the solenoid valve on the surface of the booster pipe 13 opens again, and at the same time, the air compressor 7 starts and pumps compressed air into the inner cavity of the booster tank 8 through the air pipe, pressurizing the water stored in the inner cavity of the booster tank 8 and entering the inner cavity of the booster pipe 13. The pressurized water then enters the connecting pipe section through the booster pipe 13. In the inner cavity of 10, the water pressure in the inner cavities of the connecting pipe section 10 and the water supply pipe 12 increases. When the main water pump 1 fails, the standby water pump 2 and the third gate valve 11 open and transport water to the inner cavity of the connecting pipe 16 through the standby water pipe 4. Finally, the water re-enters the inner cavity of the connecting pipe section 10 and provides fire-fighting water supply through the water supply pipe 12. After the main water pump 1 is inspected, the stepper motor 95 is turned on and drives the threaded rod 97 to rotate. During the rotation, the threaded rod 97 pulls the threaded pipe 96 through its surface thread, thereby causing the drain sleeve 93 to slide downward from the inner cavity of the drain pipe 91, exposing the drain hole 94 and draining the water accumulated in the inner cavity of the standby water pump 2, thus preventing the standby water pump 2 from freezing or rusting due to long-term non-use.
[0033] In summary, this fire-fighting water supply redundant booster integrated device, through the coordinated use of main water pump 1, main water pipe 3, air compressor 7 and booster water tank 8, boosts and delivers fire-fighting water. At the same time, with the coordinated use of main water pipe 3, backup water pipe 4 and connecting pipe 16, it provides uninterrupted water supply after the main water pump 1 fails, thereby ensuring the stability of water pressure and continuous water supply.
[0034] The technical features disclosed above are not limited to the combinations of the disclosed features with other features. Those skilled in the art can also make other combinations of the technical features according to the purpose of the utility model in order to achieve the purpose of the utility model.
