For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0027] Aircraft need to be parked in the hangar, and the front and back of the hangar are designed with a front apron and a back apron respectively. With the development of aircraft, the size of aircraft is increasing, the size of the hangar roof is also increasing, and the width of the front and back aprons is also increasing.

[0028] In the related art, rainwater or snowmelt water on the hangar roof flows directly to the front and rear yards of the hangar, and the slopes of the two yards are used for drainage.

[0029] However, in extremely cold areas with low temperatures, the snowmelt water flowing to the apron in front of or behind the depot is prone to freeze due to the low temperature, thereby affecting the operational safety of aircraft on the apron in front of or behind the depot.

[0030] In order to solve the above problems, an embodiment of the present application provides an aircraft hangar top drainage system. The solution provided by the embodiment of the present application will be described in detail below in conjunction with the drawings in the specification.

[0031] Figure 1 is a schematic diagram of a hangar roof provided by an embodiment of the present application; Figure 2 is a schematic diagram of a hangar top drainage system provided by an embodiment of the present application; Figure 3 yes Figure 2 A magnified image of the hangar roof drainage system in Figure 2.

[0032] Reference Figure 1 As shown, the front yard 900 and the rear yard 1000 are located at the front and rear sides of the hangar respectively, and the drainage area 800 is located at the left and right sides of the hangar. Figure 1 The y direction is shown in the figure, and the left and right directions of the hangar can be referred to Figure 2 The x direction is shown in .

[0033] Reference Figure 2 and Figure 3 As shown, an embodiment of the present application provides an aircraft hangar roof drainage system, including a hangar roof structure layer 100, a hangar roof side wall 200, a first drainage pipe 300, a connecting piece 400 and a second drainage pipe 500.

[0034] The top structural layer 100 is surrounded by a top side wall 200, which is used to prevent rainwater or snowmelt water from the roof from flowing to the front yard 900 or the back yard 1000. The top structural layer 100 is provided with a top water diversion ditch 110. For example, the top structural layer 100 is provided with a plurality of top water diversion ditches 110 for guiding the water flow on the hangar top.

[0035] The first drain pipe 300 has a first end and a second end, and the first end and the second end are connected through the inside. The second drain pipe 500 also has a first end and a second end, and the first end and the second end are connected through the inside. The first drain pipe 300 can be vertically arranged on the side wall of the hangar, the first end of the first drain pipe 300 is connected to the top water diversion ditch 110, the second end of the first drain pipe 300 is connected to the first end of the second drain pipe 500 through the connecting piece 400, and the second end of the second drain pipe 500 is located in the drainage area 800 of the hangar, and the drainage area 800 is far away from the front yard 900 or the back yard 1000 of the hangar. Rainwater or snowmelt water on the hangar roof is guided to the drainage area 800 of the hangar front apron 900 or the hangar rear apron 1000 away from the aircraft hangar through the hangar roof water diversion ditch 110, the first drainage pipe 300, the connecting piece 400 and the second drainage pipe 500, so as to avoid ice formation on the hangar front apron 900 or the hangar rear apron 1000, thereby avoiding affecting the operation safety of the aircraft on the hangar front apron 900 or the hangar rear apron 1000.

[0036] Continue to refer to Figure 2 and Figure 3 As shown, the connecting piece 400 is a three-way connecting piece, and the hangar top drainage system also includes a third drain pipe 700, which has a first end and a second end, and the first end and the second end are internally connected. The three-way connecting piece has a first connection port, a second connection port and a third connection port. In addition, the first connection port, the second connection port and the third connection port are internally connected. The first end of the first drain pipe 300 is connected to the first connection port of the three-way connecting piece, the first end of the second drain pipe 500 is connected to the second connection port of the three-way connecting piece, the first end of the third drain pipe 700 is connected to the third connection port of the three-way connecting piece, and the second end of the third drain pipe 700 is connected to the inspection ditch 1100 inside the hangar. In other words, the water (rainwater or snowmelt water) passing through the first drain pipe 300 can be diverted from the three-way connecting piece to the second connecting pipe or the third connecting pipe, thereby accelerating the drainage efficiency and avoiding water accumulation on the hangar top. The diameter of the third drain pipe 700 is greater than or equal to 32 mm. For example, the diameter of the third drain pipe 700 can be 50 mm.

[0037] Continue to refer to Figure 2 and Figure 3 As shown, the hangar top drainage system further includes a siphon rainwater bucket 600, which is connected to the hangar top water diversion ditch 110, and the first end of the first drainage pipe 300 is connected to the siphon rainwater bucket 600. The end of the siphon rainwater bucket 600 connected to the hangar top water diversion ditch 110 has a large opening, so that the water in the hangar top water diversion ditch 110 can be accelerated to enter the first drainage pipe 300, thereby ensuring that the water on the hangar top can be quickly drained away.

[0038] In addition, in some examples, the hangar top drainage system further includes a control valve, which is disposed on the third drain pipe 700. The control valve can control the on-off of the third drain pipe 700. For example, when the amount of water flowing out of the first drain pipe 300 is large and the second drain pipe 500 cannot be discharged in time, the control valve can be opened to drain part of the water through the third drain pipe 700 to the inspection ditch 1100 in the hangar. Alternatively, when the external temperature is low and the second drain pipe 500 is blocked by ice, the control valve can be opened to drain the water in the first drain pipe 300 through the second drain pipe 500 to the inspection ditch 1100 in the hangar.

[0039] Figure 4 This is an electrical connection block diagram of an aircraft hangar top drainage system provided in one embodiment of the present application.

[0040] Reference Figure 4 As shown, in some embodiments, the hangar top drainage system further includes an electric heating wrapping belt 1500, a controller 1300 and a power supply 1200, the electric heating wrapping belt 1500 is electrically connected to the power supply 1200 and the controller 1300 respectively, the controller 1300 is electrically connected to the power supply 1200, and the electric heating wrapping belt 1500 is wrapped on the third drain pipe 700. The power supply 1200 is used to supply power to the controller 1300 and the electric heating wrapping belt 1500, and the controller 1300 is used to control the electric heating wrapping belt 1500 to heat the third drain pipe 700, thereby preventing ice from forming inside the third drain pipe 700 and ensuring the smooth flow of the third drain pipe 700. Exemplarily, the electric heating wrapping belt 1500 can be a 380V low-temperature self-limiting electric heating belt, which is fixed to the three-way connector and / or the third drain pipe 700 by aluminum foil tape.

[0041] In addition, the hangar top drainage system further includes a temperature sensor 1400, which is disposed on the third drainage pipe 700 and is electrically connected to the controller 1300. The temperature sensor 1400 can detect the temperature of the third drainage pipe 700 in real time and feed it back to the controller 1300, so that the controller 1300 can control the electric heating wrapping belt 1500 to heat the third drainage pipe 700.
