Description

Technical Field

[0001] This application relates to the field of drone hangar technology, and more specifically, to a drone hangar and a multi-level drone hangar. Background Technology

[0002] Drone hangars are typically located outdoors. When it rains, rainwater can easily enter the hangar's storage compartments when the hangar door is opened, leading to water accumulation inside the hangar and potentially damaging the drones or other parts within the hangar. Summary of the Invention

[0003] The technical problem to be solved by this application is to provide a drone hangar and a multi-level drone hangar, which can drain water entering the drone hangar and reduce the problem of water accumulation in the hangar.

[0004] To solve the above-mentioned technical problems, this application adopts the following technical solution: In a first aspect, this application provides a drone hangar, including an outer shell, with an internal cavity for accommodating a drone. The outer shell includes a side wall and a first bottom wall, the first bottom wall being disposed at the bottom of the side wall along a first direction. The first bottom wall includes a wall body, the surface of the wall body facing away from the cavity along the first direction being a first surface, and the surface facing the cavity being a second surface. The wall body is provided with a drainage hole penetrating the wall body, and the second surface is a concave curved surface recessed towards the first surface. The first bottom wall includes a flow guiding member, which protrudes from the first surface along the first direction and is disposed around the drainage hole.

[0005] In the implementation of the above technical solution, a first bottom wall is located at the bottom of the side wall along the first direction, allowing it to collect water entering the receiving cavity. The second surface of the first bottom wall facing the receiving cavity is a concave curved surface. Simultaneously, a drainage hole penetrating the first bottom wall is provided. The concave curved surface itself has a concave arc, making it easier for water to collect at the drainage hole, allowing for faster drainage and reducing water residue in the receiving cavity. Furthermore, a flow guiding component is also provided on the first surface of the wall body, surrounding the drainage hole. Through the guidance of the flow guiding component, water can flow in the direction of the flow guiding component, avoiding important components inside the receiving cavity, such as electrical cabinets or the wings of drones.

[0006] In one embodiment, at least one drain hole is a first drain hole, and a first connecting rib is provided in the first drain hole. The first connecting rib divides the first drain hole into a first region and a second region. The first connecting rib is connected to a flow guide component corresponding to the first drain hole. The maximum height of the first connecting rib protruding from the first surface along the first direction is greater than the maximum height of the flow guide component protruding from the first surface.

[0007] In the implementation of the above technical solution, the maximum height of the first connecting rib protruding from the first surface is greater than the maximum height of the guide component (i.e., the first guide rib) corresponding to the first drain hole protruding from the first surface. This is equivalent to the first connecting rib protruding from the first surface at the farthest distance, that is, the first connecting rib is at the lowest position. Since the first guide rib is connected to the first connecting rib, when water flows out from the first drain hole, the water will flow along the first guide rib to the first connecting rib. The first connecting rib is set inside the first drain hole, rather than at the edge of the hole wall of the first drain hole. In this way, when water drips from the first connecting rib, it is easier to avoid some important components on the drone inside the cavity.

[0008] In one embodiment, the flow guiding component corresponding to the first drainage hole includes a first flow guiding rib. The first flow guiding rib includes a first flow guiding section disposed around the first region and a second flow guiding section disposed around the second region. The maximum height of the first connecting rib protruding from the first surface along the first direction is greater than the maximum height of the first flow guiding section protruding from the first surface and the maximum height of the second flow guiding section protruding from the first surface.

[0009] In the implementation of the above technical solution, since the maximum height of the first connecting rib protruding from the first surface is greater than the maximum height of the first guide section protruding from the first surface and the maximum height of the second guide section protruding from the first surface, the position of the first connecting rib is the lowest. Water can flow from the first guide section and the second guide section to the first connecting rib respectively. When dripping from the first connecting rib, it is easier to avoid some important components on the drone inside the cavity.

[0010] In one implementation, along the circumference of the first region, the first guide segment has a first position located between its two ends, and the height of the first guide segment protruding from the first surface gradually increases from the first position to both ends of the first connecting rib; and / or along the circumference of the second region, the second guide segment has a second position located between its two ends, and the height of the second guide segment protruding from the first surface gradually increases from the second position to both ends of the first connecting rib.

[0011] In the implementation of the above technical solution, the height of the first guide section protruding from the first surface gradually increases from the first position to both ends of the first connecting rib, which is equivalent to the first guide section forming a slope from the first position to both ends of the first connecting rib. This makes it easier to guide the accumulated water from the first guide section to the first connecting rib. Similarly, the height of the second guide section protruding from the first surface gradually increases from the second position to both ends of the first connecting rib, which is equivalent to the second guide section forming a slope from the second position to both ends of the first connecting rib. This makes it easier to guide the accumulated water from the second guide section to the first connecting rib.

[0012] In one embodiment, the first connecting rib has a third position located between the two ends, and the height of the first connecting rib protruding from the first surface gradually decreases from the third position to the two ends.

[0013] In the implementation of the above technical solution, the height of the first connecting rib protruding from the first surface gradually decreases from the third position to both ends, which is equivalent to the first connecting rib having two inclined guide surfaces from both ends of the first connecting rib to the third position. In this way, the water flowing in from both ends can flow into the third position respectively. That is, the third position of the first connecting rib protrudes the farthest from the first surface. When the water drips from the third position, it is easier to avoid some important components on the drone inside the cavity.

[0014] In one embodiment, at least one drain hole is a second drain hole, and the guide member corresponding to the second drain hole is a second guide rib. The second guide rib has a fourth position located between the two ends along the circumference of the second drain hole, and the height of the second guide rib protruding from the first surface gradually increases from the two ends to the fourth position.

[0015] In the process of implementing the above technical solution, the height of the second guide rib protruding from the first surface gradually decreases from the fourth position to both ends of the second guide rib. This is equivalent to the second guide rib forming a slope from the fourth position to both ends. The fourth position protrudes the farthest from the first surface. In this way, the water accumulated at both ends of the second guide rib can be guided to the fourth position and drip from the fourth position, thereby avoiding some key components on the drone.

[0016] In one embodiment, the first bottom wall includes a reinforcing rib, which protrudes from the first surface, and the height of the reinforcing rib protruding from the first surface is greater than the height of the second guide rib protruding from the first surface.

[0017] In the implementation of the above technical solution, the height of the reinforcing rib protruding from the first surface is greater than the height of the second guide rib protruding from the first surface, that is, the distance of the reinforcing rib protruding from the first surface is the farthest, thereby increasing the thickness of the reinforcing rib and improving the structural strength of the first bottom wall.

[0018] In one embodiment, at least one of the flow guiding components has a first end and a second end along the circumference of the second drain hole, the first end and the second end being connected to the reinforcing rib.

[0019] In the implementation of the above technical solution, the two ends of the flow guiding component are connected to the reinforcing ribs to form a closed area, making it easier for the flow guiding component to drain water. The reinforcing ribs can both strengthen the structure and guide water.

[0020] Secondly, this application also provides a multi-layer drone hangar, including multiple drone hangars as described in the first aspect, the multiple drone hangars being stacked along a first direction, with an opening at one end of the side wall away from the first bottom wall along the first direction, and in two adjacent drone hangars, the first bottom wall of one drone hangar closing the opening of the other drone hangar.

[0021] In the implementation of the above technical solution, the first bottom wall of one drone hangar closes the opening of another drone hangar. In this way, the top of the drone hangar does not need to be equipped with additional cover plates or other components, reducing costs. At the same time, it also facilitates drainage inside the drone hangar.

[0022] In one embodiment, the multi-layer drone hangar includes a storage layer and a protection layer. Along the first direction, the storage layer is disposed on top of the protection layer. The storage layer is used to store drones. Multiple drone hangars are stacked on top of the storage layer. The chambers in the storage layer are connected to the storage cavity. A return air vent is provided at the bottom of the storage layer. The protection layer is provided with a drainage channel. The return air vent is connected to the drainage channel.

[0023] In the implementation of the above technical solution, by setting up a protection layer and a containment layer, the containment layer can also accommodate drones, thereby increasing the number of drones that can be accommodated in the multi-level drone hangar. At the same time, since the chambers in the containment layer are connected to the containment chambers in the drone hangar, accumulated water can flow from top to bottom into the containment layer, and then flow into the protection layer through the return air vent, and be discharged from the drainage channel of the protection layer, realizing a complete drainage process.

Detailed Implementation

[0027] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0028] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this application, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0029] A drone hangar can protect drones from damage caused by severe weather, and at the same time, it can reduce damage to components inside the hangar, thus protecting the drones and their internal parts.

[0030] However, in severe weather, especially rainy days, rainwater can easily enter the hangar when the hangar door is opened. If there is no drainage system inside the hangar, water can accumulate inside, damaging the drone and its internal parts.

[0031] Therefore, please refer to Figures 1 to 3 , Figure 1 This is a schematic diagram of the structure of a drone hangar provided in an embodiment of this application; Figure 2 A top view of a drone hangar provided in an embodiment of this application; Figure 3 This is a schematic diagram of the structure of the first bottom wall provided in an embodiment of this application. In a first aspect, this application provides a drone hangar, including an outer shell 1. The outer shell 1 has an internal cavity for accommodating a drone. The outer shell 1 includes a side wall 11 and a first bottom wall 12. The first bottom wall 12 is disposed at the bottom of the side wall 11 along a first direction X. The first bottom wall 12 includes a wall body. The surface of the wall body facing away from the cavity along the first direction X is a first surface 123, and the surface facing the cavity is a second surface 121. The wall body is provided with a drainage hole 13 that penetrates the wall body. The second surface 121 is a concave curved surface recessed towards the first surface 123. The first bottom wall 12 includes a flow guiding member 14. Along the first direction X, the flow guiding member 14 protrudes from the first surface 123 and surrounds the drainage hole 13.

[0032] Please continue reading. Figure 2 Optionally, the drone hangar also includes a hangar door 5, which is installed on the outer shell 1. The hangar door 5 is used to open or close windows, which are opened on the periphery of the outer shell 1 rather than on the top of the outer shell 1, so as to reduce rainwater from entering the housing cavity.

[0033] The first bottom wall 12 includes a wall body and a flow guiding component 14, which is connected to the wall body and protrudes from the first surface 123.

[0034] The first bottom wall 12 can be a one-piece injection molded part, thereby improving the structural strength of the first bottom wall 12.

[0035] The first direction X can be the height direction, i.e., the vertical direction. Alternatively, the first direction X can be the horizontal direction. The first direction X is not limited here.

[0036] Optionally, the second surface 121 being a concave curved surface means that the thickness of the wall body gradually decreases from the outer edge to the inside, that is, the thickness of the wall body is thickest near the outer edge and thinnest near the central region. This central region can be the center of the wall body or the area near the center.

[0037] Optionally, one or more drainage holes 13 can be provided. Since the drone hangar in this embodiment can accommodate multi-rotor drones, the location of the drainage holes 13 can avoid the rotors on the drones to prevent water from dripping onto the rotors.

[0038] The shape of the drain hole 13 is not limited; it can be circular, quadrilateral, or irregular.

[0039] In this embodiment, the first bottom wall 12 is located at the bottom of the side wall 11 along the first direction X, allowing the first bottom wall 12 to collect water entering the receiving cavity. The second surface 121 of the first bottom wall 12 facing the receiving cavity is a concave curved surface. Simultaneously, a drainage hole 13 penetrating the first bottom wall 12 is provided. The concave curved surface itself has a concave arc, making it easier for water to collect at the drainage hole 13, allowing for faster drainage and reducing water residue in the receiving cavity. Furthermore, the first surface 123 of the wall body is also provided with a flow guiding component 14, which surrounds the drainage hole 13. Through the flow guiding component 14, water can flow in the direction of the flow guiding component 14, avoiding important components inside the receiving cavity, such as electrical cabinets or the wings of drones.

[0040] Please see Figure 3 and Figure 4 , Figure 4 This is a schematic diagram of the structure of the first bottom wall provided in another embodiment of this application. In one implementation, at least one drain hole 13 is a first drain hole 15. A first connecting rib 17 is provided in the first drain hole 15. The first connecting rib 17 divides the first drain hole 15 into a first region 151 and a second region 152. The first connecting rib 17 is connected to the flow guiding member 14 corresponding to the first drain hole 15. The maximum height of the first connecting rib 17 protruding from the first surface 123 along the first direction X is greater than the maximum height of the flow guiding member 14 protruding from the first surface 123.

[0041] The two ends of the first connecting rib 17 are respectively connected to the hole wall of the first drainage hole 15.

[0042] In this embodiment, the maximum height of the first connecting rib 17 protruding from the first surface 123 is greater than the maximum height of the guide component 14 (i.e., the first guide rib 16) corresponding to the first drain hole 15 protruding from the first surface 123. This means that the distance of the first connecting rib 17 protruding from the first surface 123 is the farthest, that is, the position of the first connecting rib 17 is the lowest. Since the guide component 14 is connected to both ends of the first connecting rib 17, when water flows out from the first drain hole 15, the water will flow along the guide component 14 from both ends of the first connecting rib 17 to the first connecting rib 17. The first connecting rib 17 is set inside the first drain hole 15, rather than on the edge of the hole wall of the first drain hole 15. In this way, when water drips from the first connecting rib 17, it is easier to avoid some important components on the drone inside the cavity.

[0043] Please continue reading. Figure 4 In one embodiment, the flow guiding component 14 corresponding to the first drain hole 15 is a first flow guiding rib 16. The first flow guiding rib 16 includes a first flow guiding section 161 arranged around the first region 151 and a second flow guiding section 162 arranged around the second region 152. The maximum height of the first connecting rib 17 protruding from the first surface 123 along the first direction X is greater than the maximum height of the first flow guiding section 161 protruding from the first surface 123 and the maximum height of the second flow guiding section 162 protruding from the first surface 123.

[0044] It should be noted that the first guide rib 16 has a bent part. Therefore, in some cases, when there is a lot of water on the first bottom wall 12, the water flow is relatively fast, and some of the water may not be able to flow in the direction of the first guide rib 16. When the water flow is slower, it can flow along the first guide rib 16.

[0045] The first guide section 161 is a non-closed structure, and the second guide section 162 is also a non-closed structure. After the two ends of the first guide section 161 are connected to the two ends of the second guide section 162, a closed first guide rib 16 is formed.

[0046] In this embodiment, since the maximum height of the first connecting rib 17 protruding from the first surface 123 is greater than the maximum height of the first guide section 161 protruding from the first surface 123 and the maximum height of the second guide section 162 protruding from the first surface 123, the first connecting rib 17 is at the lowest position. Water can flow from the first guide section 161 and the second guide section 162 to the first connecting rib 17 respectively. When dripping from the first connecting rib 17, it is easier to avoid some important components on the drone inside the cavity.

[0047] Please continue reading. Figure 4In one embodiment, along the circumference of the first region 151, the first guide section 161 has a first position 1611 located between the two ends, and the height of the first guide section 161 protruding from the first surface 123 gradually increases from the first position 1611 to the two ends of the first connecting rib 17; and / or along the circumference of the second region 152, the second guide section 162 has a second position 1621 located between the two ends, and the height of the second guide section 162 protruding from the first surface 123 gradually increases from the second position 1621 to the two ends of the first connecting rib 17.

[0048] The two ends of the first guide section 161 refer to the two ends that connect to the second guide section 162, and are also the positions that connect to the first connecting rib 17. In other words, one end of the first guide section 161, one end of the second guide section 162, and one end of the first connecting rib 17 converge at one position, while the other end of the first guide section 161, the other end of the second guide section 162, and the other end of the first connecting rib 17 converge at another position.

[0049] Optionally, the first position 1611 on the first guide section 161 can be a region, the position of which can be adjusted according to the first bottom wall 12 during actual production; the second position 1621 on the second guide section 162 can be a region, the position of which can be adjusted according to the first bottom wall 12 during actual production.

[0050] In a preferred embodiment of this application, the height of the first guide section 161 protruding from the first surface 123 gradually increases from the first position 1611 to both ends of the first connecting rib 17, while the height of the second guide section 162 protruding from the first surface 123 gradually increases from the second position 1621 to both ends of the first connecting rib 17.

[0051] In this embodiment, the height of the first guide section 161 protruding from the first surface 123 gradually increases from the first position 1611 to both ends of the first connecting rib 17. This is equivalent to the first guide section 161 forming a sloping surface from the first position 1611 to both ends of the first connecting rib 17, making it easier to guide accumulated water from the first guide section 161 to the first connecting rib 17. Similarly, the height of the second guide section 162 protruding from the first surface 123 gradually increases from the second position 1621 to both ends of the first connecting rib 17. This is equivalent to the second guide section 162 forming a sloping surface from the second position 1621 to both ends of the first connecting rib 17, making it easier to guide accumulated water from the second guide section 162 to the first connecting rib 17.

[0052] Please continue reading. Figure 4 In one embodiment, the first connecting rib 17 has a third position 171 located between the two ends, and the height of the first connecting rib 17 protruding from the first surface 123 gradually decreases from the third position 171 to the two ends.

[0053] Optionally, the third position 171 on the first connecting rib 17 can be a region, the position of which can be adjusted according to the first bottom wall 12 during actual production.

[0054] In this embodiment, the height of the first connecting rib 17 protruding from the first surface 123 gradually decreases from the third position 171 to both ends. This is equivalent to the first connecting rib 17 having two inclined guide surfaces from both ends of the first connecting rib 17 to the third position 171. In this way, the water flowing in from both ends can flow into the third position 171 respectively. That is, the third position 171 of the first connecting rib 17 protrudes the farthest from the first surface 123. When the water drips from the third position 171, it is easier to avoid some important components of the drone in the cavity.

[0055] Please see Figure 5 , Figure 5 These are schematic diagrams of the first bottom wall from different perspectives provided in the embodiments of this application. In one implementation, at least one drain hole 13 is a second drain hole 18, and the flow guiding component 14 corresponding to the second drain hole 18 is a second flow guiding rib 19. The second flow guiding rib 19 has a fourth position 191 located between the two ends along the circumference of the second drain hole 18, and the height of the second flow guiding rib 19 protruding from the first surface 123 gradually increases from the two ends to the fourth position 191.

[0056] It should be noted that the second guide rib 19 has a bent part. Therefore, in some cases, when there is a lot of water on the first bottom wall 12, the water flow is relatively fast, and some of the water may not be able to flow in the direction of the second guide rib 19. When the water flow is slower, it can flow along the second guide rib 19.

[0057] Optionally, the second guide rib 19 may be a non-closed structure, and the two ends of the second guide rib 19 are not connected together.

[0058] Optionally, the fourth position 191 on the second guide rib 19 can be a region, the position of which can be adjusted according to the first bottom wall 12 during actual production.

[0059] In this embodiment, the height of the second guide rib 19 protruding from the first surface 123 gradually decreases from the fourth position 191 to both ends of the second guide rib 19. This is equivalent to the second guide rib 19 forming a sloping surface from the fourth position 191 to both ends. The fourth position 191 protrudes the farthest from the first surface 123. In this way, the water accumulated at both ends of the second guide rib 19 can be guided to the fourth position 191 and drip from the fourth position 191, thereby avoiding some critical components on the drone.

[0060] Please continue reading. Figure 5Optionally, at least one drain hole 13 further includes a third drain hole 131, the drainage logic of the third drain hole 131 being the same as that of the first drain hole 15. The third drain hole 131 is provided with a second connecting rib 122, which divides the third drain hole 131 into a third region and a fourth region. The third guide ribs surrounding the third drain hole 131 are all connected to the second connecting rib 122. The second connecting rib 122 has a fifth position 1221, which protrudes the farthest from the first surface 123. Water accumulated on the third guide rib can be guided to the second connecting rib 122 and drip from the fifth position 1221.

[0061] Please continue reading. Figure 5 In one embodiment, the first bottom wall 12 includes a reinforcing rib 2, which protrudes from the first surface 123. The height of the reinforcing rib 2 protruding from the first surface 123 is greater than the height of the second guide rib 19 protruding from the first surface 123.

[0062] The reinforcing rib 2 is connected to the wall body and is integrally formed with the wall body.

[0063] In this embodiment, the height of the reinforcing rib 2 protruding from the first surface 123 is greater than the height of the second guide rib 19 protruding from the first surface 123, that is, the distance of the reinforcing rib 2 protruding from the first surface 123 is the farthest, thereby increasing the thickness of the reinforcing rib 2 and improving the structural strength of the first bottom wall 12.

[0064] Please continue reading. Figure 5 In one embodiment, at least one guide member 14 has a first end and a second end along the circumference of the second drain hole 18, and the first end and the second end are connected to the reinforcing rib 2.

[0065] Optionally, both the second guide rib 19 and the third guide rib are connected to the reinforcing rib 2.

[0066] In this embodiment, the two ends of the flow guiding component 14 are connected to the reinforcing rib 2 to form a closed area, making it easier for the flow guiding component 14 to drain water. The reinforcing rib 2 can both strengthen the structure and guide water.

[0067] Please see Figure 6 The present application provides a schematic diagram of the structure of a multi-layer drone hangar. In a second aspect, the present application provides a multi-layer drone hangar comprising multiple drone hangars as described in the first aspect. These multiple drone hangars are stacked along a first direction X. The sidewall 11 has an opening at one end along the first direction X away from the first bottom wall 12. In two adjacent drone hangars, the first bottom wall 12 of one drone hangar closes the opening of the other drone hangar.

[0068] Optionally, the first surface 123 of the first bottom wall 12 is provided with a positioning groove, which is located near the edge of the first bottom wall 12. In two adjacent drone hangars, the side wall 11 of the lower drone hangar can be inserted into the positioning groove of the first bottom wall 12 of the upper drone hangar.

[0069] In this embodiment, the first bottom wall 12 of one drone hangar closes the opening of another drone hangar. This eliminates the need for additional cover plates or other components on the top of the drone hangar, reducing costs and facilitating drainage inside the drone hangar.

[0070] Please see Figure 6 and Figure 7 , Figure 7 These are schematic diagrams of the structure of a multi-layer drone hangar from different perspectives, provided in an embodiment of this application. In one implementation, the multi-layer drone hangar includes a housing layer 3 and a protective layer 4. Along the first direction X, the housing layer 3 is disposed on top of the protective layer 4. The housing layer 3 is used to house drones. Multiple drone hangars are stacked on top of the housing layer 3. The chambers within the housing layer 3 are connected to the housing cavity. A return air vent 321 is provided at the bottom of the housing layer 3. The protective layer 4 is provided with a drainage channel 41, and the return air vent 321 is connected to the drainage channel 41.

[0071] The outer perimeter wall of the storage layer 3 has the same structure as the side wall 11 of the drone hangar, and the storage layer 3 is also equipped with a hangar door 5.

[0072] The containment layer 3 is located on top of the protection layer 4. The containment layer 3 has a return air cavity 31 inside. The drain hole 13 of the drone hangar closest to the containment layer 3 is connected to the return air cavity 31. The bottom of the containment layer 3 is provided with a return air inlet 321 that is connected to the return air cavity 31.

[0073] Optionally, the top of the housing layer 3 also has an opening, and when the multi-level drone hangar is connected to the housing layer 3, the first bottom wall 12 of the drone hangar closest to the housing layer 3 closes the opening of the housing layer 3.

[0074] Optionally, the drainage holes 13 on the first bottom wall 12 connect two adjacent receiving cavities. Along the first direction X, the drainage holes 13 are all on the same axis. In this way, the water in the receiving cavity flows from top to bottom layer by layer into the lowest receiving layer 3, and from the receiving layer 3 into the protection layer 4.

[0075] In this embodiment, by setting up a protective layer 4 and a housing layer 3, the housing layer 3 can also accommodate drones, thereby increasing the number of drones that the multi-level drone hangar can hold. At the same time, since the chambers in the housing layer 3 are connected to the housing chambers in the drone hangar, accumulated water can flow from top to bottom into the housing layer 3, and then flow into the protective layer 4 through the return air vent 321, and be discharged from the drainage channel 41 of the protective layer 4, realizing a complete drainage process.

[0076] Meanwhile, this embodiment makes full use of the return air vent 321, without the need to open a drain outlet in the housing layer 3, thereby improving space utilization and simplifying the structure and reducing manufacturing costs.

[0077] Please see Figure 8 In one embodiment, the housing layer 3 includes a second bottom wall 33, the second bottom wall 33 is provided with an inspection port that penetrates the second bottom wall 33, the inspection port is covered by an inspection cover 32, and the inspection cover 32 is provided with a return air vent 321.

[0078] In this embodiment, the return air vent 321 is located on the inspection cover 32, thereby making full use of the inspection cover 32. There is no need to open an additional drainage outlet on the second bottom wall 33, so that the inspection cover 32 not only has an inspection function, but also a drainage function, thereby improving space utilization and reducing production costs.

[0079] In one embodiment, along the first direction X, the second bottom wall 33 faces the cavity direction as a third surface, which is a concave curved surface that is recessed away from the cavity, and the return air vent 321 is lower than the third surface.

[0080] In this embodiment, the second bottom wall 33 is also a concave curved surface structure, and the return air vent 321 is lower than the third surface. In this way, the return air vent 321 on the inspection cover 32 is at the lowest position, which can collect water and facilitate the drainage of water from the return air vent 321.

[0081] Please continue reading. Figure 8 As one implementation method, the multi-layer drone hangar includes an air conditioning system, which includes an internal circulation system. The protection layer 4 has an internal circulation channel, and the return air inlet 321 is an internal circulation air inlet. The housing layer 3 is also provided with an internal circulation air outlet 332. Both the internal circulation air inlet and the internal circulation air outlet 332 are connected to the internal circulation channel.

[0082] In this embodiment, the return air vent 321 is an internal circulation air inlet, so that the second bottom wall 33 does not need to have an additional drain outlet. At the same time, when the air conditioner is running, the internal circulation air will also provide driving force for the accumulated water, causing the accumulated water to flow towards the return air vent 321, which facilitates drainage.

[0083] Please continue reading. Figure 7 In one implementation, the drainage channel 41 is located at the bottom of the protective layer 4, and the internal circulation air outlet 332 is located at the bottom of the receiving layer 3.

[0084] The internal circulation air outlet 332 is located on the second bottom wall 33.

[0085] In this embodiment, since the drainage channel 41 is located at the bottom of the protective layer 4, after the accumulated water flows through the return air inlet 321, it enters the protective layer 4 by gravity and is discharged from the drainage channel 41 at the bottom. The internal circulation air outlet 332 is located at the bottom of the receiving layer 3, that is, on the second bottom wall 33. In this way, the airflow of the internal circulation forms an angle with the flow direction of the accumulated water, which automatically realizes gas-liquid separation and prevents the airflow of the internal circulation from bringing the accumulated water from the internal circulation air outlet 332 into the interior of the receiving layer 3.

[0086] In one implementation, the air conditioning system includes a heat exchanger disposed in an internal circulation channel, and a drain channel 41 for draining the condensate generated by the heat exchanger.

[0087] Heat exchangers can exchange heat with the airflow inside the hangar.

[0088] Optionally, the protection layer 4 is also provided with an external circulation air inlet and an external circulation air outlet, which are connected to form an external circulation flow channel for heat dissipation.

[0089] Both the inner and outer circulation channels are connected to a heat exchanger (not shown in the figure) for heat exchange. This enables the air conditioning system to control the temperature inside the multi-story drone hangar, keeping it constant and beneficial for the normal operation of the hangar. The media in the inner and outer circulation channels exchange heat through the heat exchanger. Optionally, the heat exchanger can be a tube sheet heat exchanger.

[0090] Optionally, the tube sheet heat exchanger can be an integrated heat exchanger, with refrigerant flowing on one side and circulating medium flowing on the other side. The inner circulation side can be refrigerant evaporation and heat absorption, while the outer circulation side can be water-cooled or air-cooled.

[0091] Of course, in some cases, switching valves and other components can be installed in the protection layer 4. When internal circulation is needed, the switching valve will close the external circulation channel. When external circulation is needed, the external circulation channel and the internal circulation channel will be connected to each other.

[0092] In this embodiment, since the multi-story drone hangar has an air conditioning system, and the heat exchanger of the air conditioning system needs to produce condensate, the condensate needs to be discharged through the drainage channel 41. In this embodiment, the internal circulation air inlet and drainage channel 41 of the air conditioning system are fully utilized, eliminating the need to open an additional drainage outlet, reducing costs and improving space utilization.
