Description

Technical Field

[0001] The utility model relates to the field of fire-fighting devices, in particular to a fire-fighting foam liquid supply device. Background Art

[0002] As oil production continues to expand, fire safety issues are becoming increasingly important. Fires in large oil depots and oil storage facilities can have serious consequences, including explosions and fire spread. In these situations, firefighting equipment plays a crucial role, serving as a crucial line of defense in protecting these critical facilities.

[0003] Currently, firefighting systems primarily utilize foam liquid systems, foam fire extinguishing systems, and smoke fire extinguishing systems. Among these, foam liquid systems are widely used due to their high firefighting performance on liquid fires. These systems utilize a series of facilities, including a fire water source, fire water tanks, a fire foam liquid pump room, and fire foam liquid pumps. These systems combine a foam proportioning mixer with a foam generating device to apply foam to the surface of the burning liquid to extinguish the fire.

[0004] However, current firefighting foam systems have strict requirements for site conditions, requiring a large number of supporting facilities, such as fire water sources, fire foam pumps, and fire power supplies, to ensure a continuous water supply and foam spraying. Such systems require numerous construction facilities, occupy a large area, and have high construction costs. Furthermore, after the station level is adjusted or the scale is reduced, the existing firefighting system cannot adapt to the new needs, resulting in idle facilities and wasted resources. Furthermore, these systems require the site to have dual power supplies for primary loads, further increasing the system's complexity and cost, and raising the requirements for the site. In summary, existing firefighting systems face urgent challenges, such as a high dependence on site conditions, high construction and maintenance costs, and a lack of flexibility.

[0005] Therefore, a firefighting foam liquid supply device that is independent of site conditions, portable, and reusable is needed. This device can overcome the limitation of a primary load dual power supply for firefighting, reduce floor space, and lower construction costs. This will provide a more flexible, economical, and reliable fire safety guarantee for oil production. Utility Model Content

[0031] Example 1:

[0032] like Figures 1 to 4 As shown, a fire foam liquid supply device is provided in an embodiment of the present invention.

[0034] Preferably, in this embodiment, the firefighting equipment room 2 is also provided with a firefighting foam liquid supply device return port 10, which serves as a foam liquid return channel in the event of system overpressure, thereby protecting the system from overpressure damage. One end of the firefighting foam liquid supply device return port 10 passes through the skid-mounted housing structure 1 and communicates with the outside, while the other end is connected to the firefighting foam liquid diesel pump unit 4 and the firefighting foam liquid electric pump 5.

[0035] Preferably, a fuel tank 7 is also provided in the fire-fighting equipment room 2 in this embodiment. The fuel tank 7 is connected to the fire-fighting foam liquid diesel pump group 4. Diesel is stored in the fuel tank 7 to provide fuel for the fire-fighting foam liquid diesel pump group 4 to ensure the normal operation of the fire-fighting foam liquid diesel pump group 4.

[0036] Preferably, the fire foam liquid diesel pump group 4 in this embodiment is also connected to a smoke exhaust port 16, which is arranged on the box wall of the fire equipment room 2. The smoke exhaust port 16 is connected to the fire foam liquid diesel pump group 4 through a pipe to discharge the smoke and gas generated when the fire foam liquid diesel pump group 4 is in operation.

[0037] Preferably, a fire foam liquid pump control cabinet 8 is also provided in the fire-fighting equipment room 2 in this embodiment. The fire foam liquid pump control cabinet 8 is electrically connected to the fire foam liquid diesel pump group 4 and the fire foam liquid electric pump 5 to control and monitor the operating status of the fire foam liquid diesel pump group 4 and the fire foam liquid electric pump 5, and realize the start, stop and fault monitoring of the fire foam liquid diesel pump group 4 and the fire foam liquid electric pump 5.

[0038] Preferably, the skid-mounted box structure 1 in this embodiment is also provided with a drain outlet 15, which is connected to the bottom of the fire-fighting equipment room 2 and the fire-fighting foam liquid reservoir 3, and leads to an external drainage system to discharge the accumulated water in the fire-fighting equipment room 2 and the fire-fighting foam liquid reservoir 3 to prevent water accumulation and corrosion.

[0039] Preferably, the skid-mounted box structure 1 described in this embodiment is also provided with heating facilities 14, which are provided in the fire equipment room 2 and the fire foam liquid tank 3 to maintain the temperature of the fire equipment room 2 and the fire foam liquid tank 3 in a cold environment to prevent the foam liquid and equipment from being damaged by low temperature.

[0040] Preferably, a plurality of roof fans 17 are provided on the top of the skid-mounted box structure 1 in this embodiment to ventilate and dissipate heat in the fire equipment room 2 and the fire foam liquid tank 3, thereby maintaining the temperature and humidity of the fire equipment room 2 and the fire foam liquid tank 3 and preventing the internal equipment from overheating.

[0041] Preferably, the side walls of the skid-mounted box structure 1 in this embodiment are provided with a plurality of inspection doors 13 for entering the equipment room for maintenance and inspection.

[0042] Preferably, in this embodiment, the fire equipment room 2 and the fire foam liquid reservoir 3 are respectively provided with safety exits 12 as exits for evacuation of personnel in emergency situations to ensure the safety of personnel.

[0043] Example 2:

[0044] This embodiment provides a use case for the firefighting foam supply device described in Example 1. Firefighting water first enters the skid-mounted housing 1 through the firefighting foam supply device's water inlet 9. After passing through the inlet control valve, the water is delivered to the firefighting foam electric pump 5 for initial pressurization. If the electric pump 5 experiences an unexpected event, such as a power outage or failure, the firefighting foam pump detection and control system within the firefighting foam pump control cabinet 8 immediately issues a firefighting pump failure alarm. The control system then automatically switches to the firefighting foam diesel pump unit 4 to ensure a continuous supply of firefighting water. Once the pressurized firefighting water reaches the required pressure, it passes through the firefighting foam pump's outlet control valve and enters the foam proportioning device 6. Foam liquid is added from the firefighting foam reservoir 3, and the firefighting water and foam liquid are mixed in the foam proportioning device 6 to produce firefighting foam. The mixed firefighting foam then enters the firefighting foam outdoor pipeline network through the outlet of the foam mixing device 6, ultimately supplying the facilities requiring the firefighting foam, completing the automatic supply process. Throughout the entire process, the fire foam pump's inlet utilizes gravity flow to ensure the inlet pipeline is constantly filled with water. A multifunctional control valve and pressure detection device are installed at the outlet to control pressure and prevent overpressure. In the event of overpressure, an overpressure relief system is installed at the return port 10 of the fire foam supply unit. A bypass system also allows water to be directly returned to the fire water tank or pool during pump startup inspections. The activation of the fire foam pump is linked to the fire alarm signal received by the fire control system. If no human intervention is performed within 30 seconds of the fire alarm being triggered, the system will automatically activate and issue an audible and visual alarm signal.

[0045] Example 3:

[0046] This embodiment provides another firefighting foam liquid supply device. Its structure and composition are substantially the same as the firefighting foam liquid supply device described in Example 1. The difference lies in that this embodiment employs two firefighting foam liquid electric pumps 5, eliminating the firefighting foam liquid diesel pump set 4. The firefighting power supply uses a primary load, meeting firefighting power supply requirements. In actual use, the firefighting foam liquid pumps are configured to prioritize the activation of one of the firefighting foam liquid electric pumps 5. If a fault signal is detected from the first firefighting foam liquid electric pump 5, the other firefighting foam liquid electric pump 5 is immediately activated. Furthermore, the prioritized pumps are periodically replaced.

[0047] Example 4:

[0048] This embodiment provides another fire foam liquid supply device. Its structural composition is roughly the same as the fire foam liquid supply device described in Example 1. The difference is that the fire foam mixing device 6 of the fire foam liquid supply device described in this embodiment adopts a proportional foam liquid mixing device, and the fire pipe network is not normally filled with water, forming a temporary high-pressure fire foam liquid supply device and system.

[0049] In actual use, the fire pipe network and fire ring network behind the fire foam liquid pump are not filled with water. After the fire foam liquid pump is started, the pipe network is filled with foam liquid. An automatic air release valve needs to be installed in the ring pipe network.

[0050] Example 5:

[0051] This embodiment provides another fire foam liquid supply device. Its structural composition is roughly the same as the fire foam liquid supply device described in Example 1. The difference is that the fire foam mixing device 6 of the fire foam liquid supply device described in this embodiment adopts a balanced foam liquid mixing device. Foam liquid can be added during the operation of the fire foam liquid to extend the foam liquid supply time and effectively extinguish the fire.

[0052] 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 merely preferred examples of the present invention and are not intended to limit the present invention.
