Description

Technical Field

[0001] This utility model relates to a liquid storage device, for example, installed on a firefighting aircraft, for storing fire extinguishing media. Background Technology

[0002] In fire emergency rescue, fixed-wing firefighting aircraft have advantages over helicopters in terms of speed, water capacity, and relative insensitivity to airflow. Major international aircraft manufacturers have successively converted passenger aircraft into firefighting aircraft. Most firefighting aircraft use liquid storage devices to store water, relying on gravity to drop water for firefighting after the hatch is opened. However, firefighting aircraft have high ground speeds, requiring a large-scale, high-speed release of the extinguishing agent, such as 2 tons per second or higher, to ensure sufficient coverage for effective fire suppression. Furthermore, the fire scene environment is complex, and the aircraft is highly susceptible to turbulence from different directions, leading to uncontrollable deformation. Therefore, traditional liquid storage devices have poor discharge speeds and are prone to displacement due to aircraft deformation, making it difficult to seal the systems installed on the storage devices (liquid filling system, ventilation system, liquid level monitoring system, etc.). Meanwhile, because large-size integrated liquid storage devices emphasize the optimal impact of discharging large quantities of extinguishing media at once to achieve the best fire suppression effect, the discharge of large quantities of extinguishing media inevitably generates sloshing loads during the process. These sloshing loads can easily compromise the stability of firefighting aircraft, increasing the difficulty of pilot operations and potentially leading to catastrophic consequences such as aircraft wreckage and loss of life. Traditional liquid storage devices are mostly small containers with a extinguishing media capacity of no more than 3 tons, and are rarely used in storage devices with a capacity of 10 tons or more. Utility Model Content

[0003] In view of the above problems, the purpose of this utility model is to provide a liquid storage device that is easy to assemble and has high overall rigidity.

[0004] To achieve the above objectives, the liquid storage device of this utility model is a slide-type liquid storage device installed on a firefighting aircraft to store fire extinguishing media. The liquid storage device is composed of multiple segmented structures spliced ​​together. The splicing positions between the segmented structures are formed by splicing multiple first "I" beams to form a circle. In each segmented structure, "C" shaped beams are joined to enhance its rigidity. Furthermore, the liquid storage device is equipped with a first "T" shaped angle member to improve the rigidity of azimuth load.

[0005] The liquid storage device of this invention, being a slide-type liquid storage device, can be applied to the fire extinguishing agent storage and spraying system of large passenger aircraft converted into firefighting aircraft. Compared with traditional large liquid storage devices, it can meet the requirements of faster discharge rates, achieve the best impact effect on flames, and thus enhance the fire extinguishing efficiency of firefighting aircraft.

[0006] Furthermore, the liquid storage device of this invention is a segmented, pressurized liquid storage device. Each segment of the liquid storage device enters through the boarding gate and is then assembled on the aircraft without disassembling the main structure of the aircraft, thus facilitating the modification of passenger aircraft. In addition, a reinforcing structure is added to the exterior of the liquid storage device to ensure that the entire device can withstand higher airtight loads. In other words, this invention provides a liquid storage device that is easy to assemble and has high overall rigidity.

[0008] According to this utility model, the liquid storage device can connect the upper and lower wall panels of the liquid storage device using a central support member, thereby enhancing the overall strength of the device. When the firefighting aircraft is in a complex fire environment, the overall deformation of the liquid storage device remains within an acceptable range. Furthermore, by incorporating side fairings, the impact of the support structure on the discharge rate of the extinguishing medium can be reduced.

The baffles are connected to the central support member or the left and right side walls of the liquid storage device through a skeleton support rod, a "single and double ear" connector, a "T"-shaped support member, and a specially made base. The upper surface of the specially made base is connected to the upper edge of the "T"-shaped support member. The "T"-shaped support member is connected to the skeleton support rod through a "single and double ear" connector. The skeleton support rod is connected to the baffle.

[0010] According to the liquid storage device of this utility model, the baffle is easy to install and disassemble, which can reduce the shaking load generated when discharging fire extinguishing media, thereby improving the safety factor when fire extinguishing aircraft are operating.

[0011] Preferably, a peelable gasket is added between the specially designed base and the "T"-shaped support.

[0012] According to the liquid storage device of this invention, assembly tolerances can be eliminated by using peelable gaskets.

[0013] Preferably, the baffle is provided with an elliptical opening that allows the extinguishing medium to pass through normally.

[0014] According to the liquid storage device of this utility model, the baffle can ensure that the extinguishing medium can pass through normally and be released to the outside while ensuring that the shaking load is reduced.

[0015] Preferably, the liquid storage device is provided with a vent pipe interface for connection to the outside.

[0016] According to the liquid storage device of this utility model, the liquid storage device can be ventilated to the outside of the machine body by means of a vent pipe interface, so that the fire extinguishing medium can be smoothly discharged from the slide-type liquid storage device.

[0017] Preferably, a filling port cover for filling the fire extinguishing medium is provided at the front of the liquid storage device.

[0018] According to the liquid storage device of this utility model, the filling port cover allows operators to conveniently fill fire extinguishing media.

[0019] Preferably, an overflow pipe interface for discharging overflow of the extinguishing medium is provided at the top front edge of the liquid storage device.

[0020] According to the liquid storage device of this utility model, the overflowing fire extinguishing medium can be discharged through the overflow pipe via the overflow pipe interface.

[0021] Preferably, a filling pipeline interface for adding the fire extinguishing medium is provided at the rear end of the liquid storage device.

Rather, the present invention is intended to cover not only these exemplary embodiments, but also various alternatives, modifications, equivalents, and other embodiments that may be included within the spirit and scope of the present invention as defined by the appended claims.

[0059] Below, in conjunction with Figures 1 to 5 The liquid storage device 1 according to the present invention will be described.

Figure 5 This is a schematic diagram showing the structure of the baffle 5-5 of the liquid storage device 1 according to an embodiment of the present invention.

[0061] like Figure 1 As shown, the liquid storage device 1 of this utility model embodiment is, for example, a slide-type liquid storage device installed on a fire-fighting aircraft to store fire extinguishing media.

[0062] (Structure of liquid storage device 1)

[0063] The following reference Figures 2 to 5 The structure of the liquid storage device 1 according to the present invention will be described.

[0064] (1) Large fixed-wing fire extinguishing aircraft are often modified from large passenger aircraft. To achieve rapid discharge of extinguishing agents, the integrated liquid storage device can adopt a slide-type structure design. The inclined design facilitates the discharge of extinguishing agents from the bottom of the liquid storage device, reducing the residual amount of extinguishing agents. However, due to its large size, the device is difficult to install and fix inside the fuselage. To solve this problem, this utility model adopts a method of assembling the liquid storage device in sections under the frame, and then transporting it from the boarding gate to the aircraft for installation. The liquid storage device box can be divided into sections as needed according to the size of the boarding gate of the fixed-wing aircraft. The splicing position of the two liquid storage devices adopts a design of splicing four "I" beams in a circle. Each liquid storage device can be connected by "C" beams, and a design of connecting "T" angle members with the lower edge strip of the "I" beams is adopted to achieve the purpose of improving the overall rigidity of the device, thereby being able to bear a larger airtight load.

[0065] Specifically, in this embodiment, such as Figure 2 As shown, the liquid storage device 1 is typically assembled in sections and then joined on-board to facilitate entry into the aircraft through the boarding gate. To ensure the strength and sealing of the sections, a ring of I-beams 2-1 and 2-2 is usually joined together. The lower edges of multiple (four in this embodiment) I-beams 2-1 and 2-2 are connected to the front and rear upper wall panels, namely the front upper wall panel 2-3 and the rear upper wall panel 2-4. The joints are sealed by applying sealant to the bonding surface and filling the corners. Fasteners passing through the liquid storage device housing wall panels are wet-jointed.

[0066] In addition, such as Figure 2 As shown, each liquid storage device can be connected with a "C"-shaped beam, such as the upper "C"-shaped beam 2-5 and the two side "C"-shaped beams 2-6, to enhance its rigidity. The lower edge of the "C"-shaped beam is connected to a ring of wall panels. For example, the lower edge of the upper "C"-shaped beam 2-5 is connected to the upper wall panel 2-7, and the lower edge of the two side "C"-shaped beams 2-6 is connected to the side wall panel 2-8.

[0067] In addition, such as Figure 2 As shown, the yaw load stiffness enhancement adopts a design form in which "T"-shaped angle rod 2-9 is connected to the lower edge strip of "I" beam 2-10. The end of the angle rod and the lower edge strip of the beam are connected to the front and rear wall panels, namely the front upper wall panel 2-11 and the rear upper wall panel 2-12.

[0068] (2) In order to ensure that the extinguishing medium can be smoothly discharged from the liquid storage device, the liquid storage device needs to be ventilated to the outside of the machine body during discharge. Ventilation pipe interface, liquid level sensor interface, filling cap, overflow pipe interface, and filling pipeline interface can be installed as needed according to the requirements of ventilation area, filling speed, and filling time.

[0069] Specifically, in this embodiment, such as Figure 3As shown, to ensure the smooth discharge of the extinguishing agent from the liquid storage device 1, the liquid storage device 1 needs to be vented to the outside of the fuselage during discharge. Additionally, to facilitate the filling, refilling, and overflow of the extinguishing agent, corresponding interfaces can be installed on the wall panels of the liquid storage device 1 as needed. The vent pipe interface 3-1 of the liquid storage device 1 can be connected to the top skin of the fuselage via an external vent pipe. To facilitate the filling of the extinguishing agent by operators, a filling cap 3-2 for the extinguishing agent can be installed at the front end of the liquid storage device 1. An overflow pipe interface 3-3 is installed at the top leading edge of the liquid storage device 1, and the overflow pipe route is arranged downwards from this overflow pipe interface 3-3, which can be connected to the fuselage overflow port. The refilling pipe interface 3-4 on the liquid storage device 1 is located at the rear of the liquid storage device 1. To ensure the accuracy of the loading volume of the liquid storage device 1 and to monitor the refilling process, liquid level sensor interfaces 3-5 can be installed at different heights of the liquid storage device 1 as needed.

[0070] (3) Due to the large size of the liquid storage device, it is prone to deformation during the movement of the firefighting aircraft, leading to leakage of the extinguishing medium. To solve this problem, the usual practice is to add supports to the liquid storage device to enhance the rigidity of the overall structure. However, adding only supports will affect the flow rate of the extinguishing medium, thus affecting the extinguishing efficiency; adding only a straightener can reduce the impact on the flow rate, but the straightener itself has no load-bearing capacity and poor resistance to deformation. This utility model uses a simple mechanism connection form, with an "I" beam as the main load-bearing component, a "T" angle bracket connecting the web of the "I" beam to the upper and lower wall panels, and a straightener connecting the upper and lower sides of the "I" beam. The entire mechanism is assembled under the premise of ensuring the fastener installation requirements, and the fastener openings connecting the "T" angle bracket to the upper and lower wall panels of the liquid storage device are sealed.

[0071] Specifically, in this embodiment, such as Figure 4 As shown, the liquid storage device 1 of this embodiment of the invention has a central support member 2 internally. In the central support member 2, the upper and lower edges of the "I"-beam 4-1 are connected to the left and right rectifier plates 4-3 and 4-4 of the liquid storage device 1, mainly bearing the vertical load when the liquid storage device 1 deforms. The "T"-shaped angle bracket 4-2 is connected to the "I"-beam 4-1 and the upper and lower wall panels of the liquid storage device 1. To reduce the impact of the support structure on the discharge rate of the extinguishing medium, rectifier plates 4-3 and 4-4 are provided on the left and right sides of the liquid storage device 1. Furthermore, the number of "I"-beams 4-1 can be defined according to the deformation of the fire-fighting aircraft under aerodynamic loads, i.e., the length of the entire liquid storage device 1 in the heading F.

[0072] (4) To address the swaying load problem inevitably generated during firefighting aircraft operations, this utility model designs a baffle with a stable structure, high degree of freedom (the number can be adjusted according to the magnitude of the swaying load), and easy installation and disassembly. The main load-bearing structure of the baffle is an "I"-shaped beam that runs through the middle support member and the left and right side walls of the box. The ends of the "I"-shaped beam are connected to the "T"-shaped support members through "single and double ear" joints. At the same time, the ends of the "T"-shaped support members are fixed to the middle support member and the left and right side walls by two specially machined base parts. In addition, baffles with elliptical openings are set on the upper and lower sides of the "I"-shaped beam. While ensuring that the swaying load is reduced, the fire extinguishing medium can also pass through the area normally and be released outward.

[0073] Specifically, in this embodiment, such as Figure 5 As shown, the specially designed base 5-1 is connected to the support structure of the aforementioned "I"-beam 4-1 and the rectifier plate 5-5. The upper surface of the specially designed base 5-1 is connected to the upper edge of the "T"-shaped support 5-2. The "T"-shaped support 5-2 is connected to the frame support rod via a "single / double ear" connector 5-3. To eliminate assembly tolerances, a peelable gasket 5-4 can be added as needed between the specially designed base 5-1 and the "T"-shaped support 5-2. Connected to the frame support rod is a baffle 5-5 to reduce sway load. The baffle 5-5 has an elliptical opening that allows the extinguishing medium to pass through normally. Thus, in the liquid storage device 1 of this embodiment, the impact load of the extinguishing medium is transferred from the baffle 5-5 to the frame support rod, the "single / double ear" connector 5-3, and the "T"-shaped support 5-2, and then transmitted through the connection between the specially designed base 5-1 and the central support 2 and the left and right side walls. In addition, the number of baffles 5-5 can be determined according to the magnitude of the shaking load that the liquid storage device 1 bears during actual firefighting operations, which allows for a high degree of freedom.
