Compared with the prior art that requires disassembly of the upper and lower cabins of the unmanned aerial vehicle, the present application can improve the watertightness, operability and ease of use of the dual-purpose water and air unmanned aerial vehicle.

[0035] Specifically, the cabin shell is the cabin outer shell of the water-air dual-purpose unmanned aerial vehicle.

[0036] The connector assembly 3 includes a plurality of cables 31, which are arranged at intervals in the receiving hole 11, and the plurality of cables 31 are respectively partially arranged in the sealing rubber 2, and each cable 31 is respectively connected to the energy system, power system and airborne equipment system of the water-air dual-purpose unmanned aerial vehicle.

[0039] The cable 31 includes a cable male head 311 and a cable female head 312. The cable male head 311 is partially inserted into the sealing rubber 2, and the cable female head 312 is partially inserted into the sealing rubber 2.

[0040] refer to Figures 5 to 7 The water-air dual-purpose unmanned aerial vehicle joint device also includes a first sealing component 5 and a second sealing component 6.

[0041] Specifically, the first direction is the axial direction of the nacelle shell 1 , and the second direction is the radial direction of the nacelle shell 1 . Furthermore, the radial direction of the nacelle shell 1 is a direction parallel to the upper surface direction of the nacelle shell 1 .

[0042] refer to Figure 4 and Figure 6 The flange cover 4 includes a base plate portion 41, an arc portion 42 and a supporting portion 43. The base plate portion 41 is arranged on the outer side wall of the cabin shell 1, the base plate portion 41 is arranged around the accommodating hole 11, the arc portion 42 is covered above the accommodating hole 11, the arc portion 42 is arranged in the middle of the base plate portion 41, the supporting portion 43 is arranged below the arc portion 42, and the supporting portion 43 is arranged around the arc portion 42. The base plate portion 41 and the arc portion 42 are connected in an arc transition, and the arc portion 42 is streamlined.

[0043] Specifically, the abutting portion 43 is annular, and one end of the abutting portion 43 away from the arc portion 42 extends into the accommodating hole 11 to abut against the sealing rubber 2 .

[0044] Specifically, the arc portion 42 and the base plate portion 41 adopt R10 smooth rounded transition, and the flange cover 4 is a streamlined structure. Under the same conditions, the underwater coefficient of the arc portion 42 of the present application is 0.005, which is much smaller than the hemispherical (dome) drag coefficient of 0.015 and the cylindrical drag coefficient of 1.2, and can greatly reduce the fuselage drag of the cross-medium water-air dual-purpose unmanned aerial vehicle.

[0045] refer to Figure 6 and Figure 7 The first sealing assembly 5 includes a first rubber ring 51 and a first mounting groove 52, and the second sealing assembly 6 includes a second rubber ring 61 and a second mounting groove 62. The outer wall of the cabin shell 1 is provided with a first mounting groove 52 and a second mounting groove 62 at intervals. The first mounting groove 52 is arranged around the accommodating hole 11. One end of the first rubber ring 51 is arranged in the first mounting groove 52, and the other end of the first rubber ring 51 protrudes from the first mounting groove 52 and is used to abut against the base plate portion 41. The side of the first rubber ring 51 away from the second rubber ring 61 is also used to abut against the abutting portion 43 to achieve sealing of the cabin shell 1 and the flange cover 4 in the first direction. The second mounting groove 62 is arranged around the first mounting groove 52, one end of the second rubber ring 61 is arranged in the second mounting groove 62, and the other end of the second rubber ring 61 protrudes from the second mounting groove 62 and is used to abut against the base plate portion 41 to achieve sealing of the cabin shell 1 and the flange cover 4 in the second direction.

[0046] Specifically, the first rubber ring 51 and the second rubber ring 61 are both watertight O-type rubber rings. The specifications of the first rubber ring 51 are 2×52 mm, the specifications of the second rubber ring 61 are 2×60 mm, the first installation groove 52 and the second installation groove 62 are both rectangular grooves, the first installation groove 52 matches the first rubber ring 51, and the second installation groove 62 matches the second rubber ring 61.

[0047] The first installation groove 52 and the second installation groove 62 are both rectangular grooves, suitable for dynamic sealing and static sealing. At the same time, the first rubber ring 51 and the second rubber ring 61 are combined and use axial and radial combined sealing. The flange cover 4 is used to provide pressure to compress the first rubber ring 51 and the second rubber ring 61. After being compressed, the first rubber ring 51 and the second rubber ring 61 always tend to restore the original cross-section, generating a self-compression force effect. When the first rubber ring 51 and the second rubber ring 61 are respectively installed in the first installation groove 52 and the second installation groove 62, the contact stress distribution can be approximately described by a parabola:

[0048]

[0049] Where S is the contact width, σ max —Maximum contact stress

[0050] The compression rate W of the first installation groove 52 or the second installation groove 62 is usually calculated using the following empirical formula:

[0051]

[0052] Wherein D0 is the cross-sectional diameter of the first mounting groove 52 or the second mounting groove 62 in a free state, and h is the distance between the bottom of the first mounting groove 52 or the second mounting groove 62 and the sealing surface (i.e., the cross-sectional height of the first rubber ring 51 and the second rubber ring 61 after compression).

[0053] The first rubber ring 51 and the second rubber ring 61 can have a longer service life when the compression rate does not exceed 15%-20% of the original cross section.

[0054] In summary, after relevant calculations and structural design, the flange cover 4 provides pressure to control the compression rate of the first rubber ring 51 and the second rubber ring 61 to 17%. At the same time, a small amount of silicone grease is applied to the first rubber ring 51 and the second rubber ring 61 to compensate for the insufficient smoothness of the sealing surface of the first rubber ring 51 and the second rubber ring 61 and to play a lubricating role.

[0055] refer to Figures 1 to 4 The water-air dual-purpose unmanned aerial vehicle connector device also includes a fixing member 7, a first fixing hole 411 is provided on the base plate portion 41, and a second fixing hole 12 is provided on the cabin shell 1. The first fixing hole 411 and the second fixing hole 12 are arranged correspondingly, and the fixing member 7 is used to sequentially pass through the first fixing hole 411 and the second fixing hole 12 to achieve a fixed connection between the cabin shell 1 and the base plate portion 41. The number of the fixing member 7, the first fixing hole 411, and the second fixing hole 12 are all multiple, and the multiple first fixing holes 411 are arranged around the circumference of the base plate portion 41, and the multiple second fixing holes 12 are arranged around the cabin shell 1.

[0056] Specifically, the fixing member 7 is an M5 fastening screw, and the first fixing hole 411 and the second fixing hole 12 are M5 fastening threaded holes.

[0057] The joint device of the present application also has the characteristic of good pressure resistance, and the wall thickness of the flange cover 4 is determined by performing pressure resistance design on the flange cover 4 .

[0058] The specific operation is to determine the relevant environmental parameters according to the working environment and mission requirements of the cross-medium water-air dual-purpose unmanned aerial vehicle, the working depth range h∈[0,50]m, the seawater density ρ∈[1.02,1.07]g / cm 3 , gravitational acceleration g∈[9.780,9.832]m / s 2 , atmospheric pressure p 大气=1.01325×10 5 pa, so the maximum working pressure p of the cross-medium water-air dual-purpose unmanned aerial vehicle can be obtained max =ρ max g max h max +p 大气 =6.27337×10 5 pa, considering possible material defects, calculation formula errors, ultra-deep and overpressure in operation and other unsafe factors, the pressure hull subjected to external pressure should be designed and calculated according to the calculated pressure, which is taken as 1.5 times the maximum working pressure, so the calculated pressure P j =1.5p max =9.410055×10 5 pa.

[0059] According to the design requirements of the cross-medium water-air dual-purpose unmanned aerial vehicle, the cabin material is determined to be transparent photosensitive resin, and then the basic material parameter tensile strength (tensile strength) σ b ∈[44×10 6 ,62×10 6 ]pa.

[0060] When a spherical pressure shell (spherical shell) is subjected to uniform external pressure, it can maintain its spherical shape and be uniformly compressed. At this time, the uniform mid-surface compressive stress is Where P is the uniform external pressure; R is the radius of the mid-surface of the spherical shell; and t is the thickness of the spherical shell. Considering the requirements for safe operation, the shell plate stress σ is The obtained spherical shell plate stress σ should satisfy: σ≤0.85σ s , σ s is the yield strength of the material, and transparent photosensitive resin is a brittle material, so σ b Minimum value instead of σ s The ellipsoidal shell is calibrated with an equivalent radius R d As the radius of the spherical shell, Where D0 is the inner diameter of the ellipsoid, D1 is the outer diameter of the ellipsoid, and H is the depth of the ellipsoid. According to the above content, the minimum wall thickness of the cross-medium water-air dual-purpose unmanned aerial vehicle is theoretically calculated and determined, and the maximum value is taken as the overall wall thickness of the cabin.

[0061] The flange cover 4 is approximated as an ellipsoidal shell, and the minimum thickness of the shell calculated according to the above analysis is: min =1.2830mm.

[0062] Considering that the internal pressure of the joint device is approximately equal to the atmospheric pressure p 大气 =1.01325×10 5 pa is much smaller than the external pressure (maximum working pressure) p of the joint device max =ρmax g max h max +p 大气 =6.27337×10 5 pa, no internal pressure resistance test is performed here.

[0063] The steps of using the water-air dual-purpose unmanned aerial vehicle connector of the present application include:

[0064] When the cross-media water-air dual-purpose unmanned aerial vehicle is about to perform a mission, first connect the corresponding male ends of the cables 31 with the female ends of the cables 31 to start the cross-media water-air dual-purpose unmanned aerial vehicle. After manual debugging and inspection, install the first rubber ring 51 to the corresponding first mounting groove 52 of the cabin shell 1, and install the second rubber ring 61 to the second mounting groove 62. Finally, fasten the flange cover 4 to the cabin shell 1 through threads to complete the installation. The cross-media water-air dual-purpose unmanned aerial vehicle can perform related tasks normally. When the cross-media water-air dual-purpose unmanned aerial vehicle completes its mission and flies back, first remove the flange cover 4, then remove the first rubber ring 51 and the second rubber ring 61 from the corresponding first mounting groove 52 and the second mounting groove 62 of the cabin shell 1 respectively, then disconnect the corresponding cable male heads and cable female heads to shut down the cross-media water-air dual-purpose unmanned aerial vehicle, and finally charge the energy system of the cross-media water-air dual-purpose unmanned aerial vehicle through the cable 31 corresponding to the energy system, or perform other operations on the cross-media water-air dual-purpose unmanned aerial vehicle.

[0065] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention's specification and drawings, or directly / indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
