[0038] First of all, the utility model mainly relates to any scenario where liquid accumulation in aircraft, ground transportation vehicles and outdoor devices requires rapid discharge. The liquid at these locations is prone to carry solid sediments such as mud and sand, and a more efficient liquid discharge solution is required. In particular, the utility model relates to the discharge of water accumulation at the liquid accumulation location under the door frame of the aircraft cabin, but is not limited to the discharge of water accumulation at this location.
[0039] As used herein, the term "connected" is intended to describe that there is a direct fluid pathway from one component to another component, so that fluid can flow from one component to the other component.
[0040] Directional terms used herein, such as "top", "bottom", "upper", "lower", "inside", "inward", "outside" and "outward", are used to assist in describing the present invention according to the directions of the embodiments shown in the drawings. Unless otherwise specified, such as "horizontal direction", "direction of gravity", etc., directional terms are not absolute up, down, horizontal, vertical, etc., and should not be interpreted as limiting the present invention to any particular direction.
[0041] As used herein, the terms "comprising," "having," "including," and variations thereof are intended to serve as open-ended transitional phrases, terms or words requiring the presence of specified elements / steps and also allowing for the presence of other elements / steps.
[0042] In the present invention, unless explicitly stated to the contrary, the terms “first”, “second”, etc. are not intended to indicate any difference in order, position, quantity or importance, but are merely used as labels to distinguish different positions or components.
[0043] Finally, the numerical values given in each embodiment are only for illustration and are not intended to limit the scope of the present invention.
[0044] In a non-limiting example, the utility model is used to discharge liquid from a liquid gathering place inside a device to the outside of the device through the liquid discharge port 200, wherein the liquid at the liquid gathering place is prone to entrain solid sediments such as mud and sand.
[0045] In a non-limiting example, the liquid discharge assembly 100 of the present invention includes a first pipe 110, which is connected to the liquid gathering place from below. In addition, the middle section of the first pipe has an opening for connecting a pipe downstream of the fluid path. The inner diameter of the first pipe 110 can be selected based on the expected flow rate of the liquid from the liquid gathering place.
[0046] The first pipe 110 may be a conventional straight pipe, and may be generally divided into an upper end 111, a first pipe middle section, and a lower end 112. Preferably, the upper end 111 may be connected from below to an interface such as a floor drain where liquids gather. Preferably, the first pipe middle section extends in the direction of gravity.
[0047] In a non-limiting example, the liquid discharge assembly 100 of the present invention includes a sediment collection device 130 , which can be connected to the lower end portion 112 of the first pipe 110 from below.
[0048] Preferably, the sediment collecting device 130 is located vertically below the lower end 112 of the first pipe 110 in the gravity direction for collecting sediments. Specifically, if fixed sediments are entrained in the liquid, the solid sediments will directly sink into the sediment collecting device 130 under the action of gravity.
[0049] Preferably, the sediment collecting device 130 includes a accommodating space for accommodating sediments, and the accommodating space has a certain depth for accommodating a certain amount of sediments and preventing the sediments from being washed away and rolled away by excessive water flow.
[0050] Preferably, the sediment collecting device 130 includes a containing space and a cleaning opening leading to the containing space, and the cleaning opening can be selectively opened and closed, so that maintenance personnel can clean the sediment in the containing space during aircraft maintenance.
[0051] In an optional example, the sediment collecting device includes a receiving space and a joint connected to the lower end 112 of the first pipe 110, and the joint is configured to be detachably connected so that maintenance personnel can clean the sediment in the receiving space. The detachable connection form can be, but is not limited to, a threaded connection, a snap connection, a flange connection, etc.
[0052] In a non-limiting example, the liquid discharge assembly 100 of the present invention includes a second pipe 120, a first end 121 of the second pipe 120 is connected to the first pipe middle section of the first pipe 110 at an angle, and a second end 122 of the second pipe 120 is connected to the liquid discharge port 200. The inner diameter of the second pipe 120 can be selected based on the expected flow rate of the liquid from the liquid gathering place.
[0053] As the liquid entrained solid sediments continue to enter the liquid discharge assembly 100, the liquid in the sediment collection device 130 overflows to a level higher than the lower end 112 of the first pipe 110, but the solid sediments are all deposited at the bottom, so the liquid re-enters the middle section of the first pipe and continues to flow from the first end 121 of the second pipe 120 to the downstream of the liquid flow path.
[0054] Preferably, according to the specific setting environment of the liquid discharge component 100 in the device, the first end 121 of the second pipe 120 can be connected to the first pipe middle section of the first pipe 110 vertically or even tilted upward, and the connection angle α (from the extension direction of the first pipe 110 to the extension direction of the first end 121 of the second pipe 120) can be between 60 degrees and 90 degrees, preferably between 80 degrees and 90 degrees, to prevent the liquid carrying solid sediments from flowing directly into the second pipe 120 along the pipe wall of the first pipe 110, and to avoid excessive liquid from accumulating in the first end 121 of the second pipe 120.
[0055] In the above example, the second pipe 120 also includes a continuous first bend 123 and a second pipe middle section 124, wherein the first bend 123 is bent ninety degrees, allowing the second pipe middle section 124 to extend in the direction of gravity, facilitating the liquid to flow smoothly downstream and be discharged from the liquid discharge port 200.
[0056] Preferably, the liquid discharge assembly 100 may include two second pipes 120, so that the liquid discharge speed is faster and the reliability and stability of the liquid discharge can be increased.
[0057] The first end portions 121 of the two second pipes 120 may be connected to the same height of the middle section of the first pipe, so that there is no significant difference in the liquid discharge amounts of the two second pipes 120 .
[0058] In a non-limiting example, the liquid drain assembly 100 of the present invention is used to drain the accumulated water at the liquid gathering place below the door frame of an aircraft, and the liquid drain port 200 is arranged on the skin below the door frame and connected to the external environment of the aircraft.
[0059] In the above embodiment, the liquid discharge assembly 100 further includes a one-way valve 140. The one-way valve 140 is disposed at the middle section of the second pipe 120, and selectively connects or blocks the fluid flow path according to the pressure difference.
[0060] The main function of the one-way valve 140 is to discharge liquid in one direction and prevent the cabin gas from leaking during the operation of the aircraft. The air pressure is low at high altitude during flight, and the cabin is pressurized to keep the passengers comfortable. When the pressure difference between the air pressure in the cabin and the air pressure of the external environment is greater than a predetermined value, the one-way valve 140 blocks the fluid communication of the second pipeline 120.
[0061] The present invention will be further described below in conjunction with specific embodiments and drawings. More details are elaborated in the following description to facilitate a full understanding of the present invention. However, the present invention can obviously be implemented in a variety of other ways different from the description. Those skilled in the art can make similar generalizations and deductions based on actual application situations without violating the connotation of the present invention. Therefore, the protection scope of the present invention should not be limited by the content of this specific embodiment.
[0062] Figure 1 The figure schematically shows a perspective view of a liquid discharge assembly 100 according to an embodiment of the present invention.
[0063] In this embodiment, the upper end portion 111 of the first pipe 110 is connected from below to an interface such as a floor drain where liquid gathers. A first pipe middle section of the first pipe 110 extends in the direction of gravity.
[0064] like Figure 1 As shown, the liquid discharge assembly 100 includes two second pipes 120 , and the first ends 121 of the two second pipes 120 are connected to the first joint 150 , and the two first ends 121 extend in the horizontal direction and in opposite directions.
[0065] The first joint 150 is disposed at the first pipe middle section of the first pipe 110 and is an expanded diameter portion. It is understood that the form of the first joint 150 is not limited thereto, but may also be a protruding joint connected to the first pipe middle section of the first pipe 110, and the second pipe 120 is connected to the protruding joint.
[0066] like Figure 1 As shown, the two second pipes 120 both include a continuous first bend 123 , a second pipe middle section 124 and a second bend 125 .
[0067] The first bend 123 is bent ninety degrees to allow the second pipe middle section 124 to extend in the gravity direction, and the second bend 125 is bent ninety degrees to allow the two second ends 122 to extend toward each other in the horizontal direction, so that the second ends 122 of the two second pipes 120 are connected to the second joint 160, and the second joint 160 is connected to the liquid discharge port 200.
[0068] The liquid in the cabin of the aircraft flows into the liquid discharge assembly 100 by gravity at the liquid gathering place. If there are fixed sediments in the liquid, the solid sediments will sink directly into the sediment collection device 130. In order for the normal operation of the drainage function, the sediment collection device needs to be cleaned regularly.
[0069] As the liquid entrains the solid sediments and continues to enter the liquid discharge assembly 100, the liquid in the sediment collection device 130 overflows to a level higher than the lower end 112 of the first pipe 110, but the solid sediments are all deposited at the bottom, so the liquid re-enters the middle section of the first pipe and enters the left and right second pipes 120 from the first joint 150. When the one-way valve 140 is connected, the liquid continues to pass through the one-way valve 140, converges at the second joint 160, and finally is discharged out of the aircraft through the liquid discharge port 200.
[0070] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention is clearly and completely described above in combination with the specific embodiments of the present invention and the accompanying drawings.
[0071] Although various embodiments have been described above, it should be understood that the embodiments described are part of the embodiments of the present invention, rather than all of the embodiments, and they are presented in an exemplary rather than limiting manner. It is obvious to those skilled in the relevant art that the disclosed subject matter can be implemented in other specific forms without departing from its spirit and essential features.
[0072] Therefore, the embodiments described above are considered to be illustrative rather than restrictive in all aspects, and are not to be used as a basis for limiting the present invention in any way.
[0073] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention. The present disclosure also includes various modifications and modifications within the equivalent scope. In addition, various combinations and methods, further including only one element, more than one or less than one other combinations and methods also belong to the scope and scope of thought of the present disclosure.
