[0004] In order to improve the long-term sealing performance of the target drone equipment cabin, the present application provides a sealing structure for the target drone water recovery equipment cabin.

[0005] The present application provides a sealing structure for a target drone water recovery equipment cabin, which adopts the following technical solution:

[0006] A sealing structure for a target drone's water recovery equipment cabin comprises a groove opened in the circumference of an equipment cabin connection frame, an inflatable rubber tube is wound in the groove, an installation groove is penetrated through the equipment cabin connection frame, an inflatable tube port of the inflatable rubber tube is fixedly arranged in the installation groove, an auxiliary sealing structure is arranged at one end of the inflatable tube port of the inflatable rubber tube away from the inflatable rubber tube, and the auxiliary sealing structure is used to seal the inflatable tube port.

[0007] By adopting the above technical solution, the air-tightness of the equipment compartment is improved by using an inflatable rubber tube in combination with the skin. At the same time, the inflatable pipe opening is increased, and the inflatable sealing tube is sealed by using an auxiliary sealing structure, thereby effectively improving the long-term sealing performance of the inflatable rubber tube and further improving the sealing performance and sealing time of the equipment compartment.

[0008] Preferably, the auxiliary sealing structure comprises a sealing plug, which is inserted into an end of the inflation pipe opening away from the inflation rubber tube, and has an interference fit with the inflation pipe opening.

[0009] By adopting the above technical solution, a sealing plug is used to seal the inflation pipe opening, and an interference fit is used to further improve the sealing between the sealing plug and the inflation pipe opening, thereby effectively improving the sealing of the inflation rubber tube, thereby improving the sealing between the inflation rubber tube and the skin and the sealing time.

[0010] Preferably, the auxiliary sealing structure includes a gas cylinder, which is arranged on the outside of the equipment cabin connection frame. A fixing structure is provided on the equipment cabin connection frame, and the fixing structure is used to fix the gas cylinder. The inflation end of the gas cylinder is connected to the inflation pipe mouth.

[0011] By adopting the above technical solution and utilizing the connection between the gas cylinder and the inflatable rubber tube, when the flight mission takes a long time and the target aircraft is difficult to recover, the inflatable rubber tube can be replenished with air through the gas cylinder at any time, thereby effectively increasing the service life of the inflatable rubber tube and further improving the sealing between the inflatable rubber tube and the skin.

[0012] Preferably, the fixing structure includes an upper support plate and a lower support plate fixedly arranged on the equipment cabin connecting frame, the gas cylinder is clamped between the upper support plate and the lower support plate, and a strap is fixedly arranged on the equipment cabin connecting frame, the strap is wrapped around the circumference of the gas cylinder and is used to fix the gas cylinder between the upper support plate and the lower support plate.

[0033] The present application is further described in detail below in conjunction with the accompanying drawings.

[0034] An embodiment of the present application discloses a sealing structure for a target drone water recovery equipment cabin.

[0035] Embodiment 1:

[0036] Reference Figure 1 and Figure 2 The sealing structure of the target drone water recovery equipment cabin includes a groove opened in the circumference of the equipment cabin connection frame 1, and an inflatable rubber tube 2 is wound in the groove. The skin 6 is riveted to the equipment cabin, and the inflatable rubber tube 2 is pressed into the groove to form a seal. An installation groove is opened on the equipment cabin connection frame 1, and the inflatable pipe port 3 of the inflatable rubber tube 2 is penetrated in the installation groove. A sealing plug 41 is fixedly provided at one end of the inflatable pipe port 3 away from the equipment cabin, and the sealing plug 41 and the inflatable pipe port 3 are interference fit.

[0037] In this embodiment, the inflatable rubber tube 2 can be made of fluororubber. The polymer structure of fluororubber makes it have good elasticity and resilience, and can quickly restore to its original state when subjected to external force, thereby ensuring the reliability of sealing. At the same time, it has good wear and corrosion resistance, and can effectively prevent seawater from corroding the rubber tube and reducing the air tightness.

[0038] Alternatively, in some other embodiments, the inflatable rubber tube 2 may be made of polyurethane rubber, which has better wear resistance. Laboratory test results show that its wear resistance is 3 to 5 times that of natural rubber, and even up to 10 times in actual applications, thereby effectively preventing seawater from corroding the rubber tube and causing a reduction in air tightness. At the same time, polyurethane rubber has excellent strength and elasticity, can withstand higher pressure without being easily broken or deformed, and can further improve the sealing performance.

[0039] In this embodiment, the sealing plug 41 is an auxiliary sealing structure 4, and the sealing plug 41 can be used to seal the inflation pipe opening 3 well, thereby effectively avoiding the problem of reduced sealing caused by leakage of the inflation rubber tube 2. At the same time, when the sealing plug 41 is used in this embodiment, when the flight mission cycle is short, the target drone is easy to recover and the recovery time is short, the sealing can be completed by using the sealing plug 41 to plug after inflation before flight.

[0040] The implementation principle of the sealing structure of the target drone's water recovery equipment compartment in an embodiment of the present application is: by utilizing the cooperation between the inflatable rubber tube 2 and the skin 6, the sealing performance of the equipment compartment is effectively improved, and at the same time, a sealing plug 41 is added to further improve the sealing performance of the inflatable rubber tube 2, thereby effectively avoiding damage to the onboard equipment caused by the entry of seawater into the front fuselage within the specified recovery time.

[0041] Embodiment 2:

[0042] Reference Figure 3 and Figure 4 , the difference between this embodiment and the first embodiment is that the auxiliary sealing structure 4 in this embodiment does not adopt the form of a sealing plug 41. In this embodiment, a gas cylinder 42 is provided on the equipment cabin connection frame 1, wherein the gas cylinder 42 is fixed by a fixing structure 5 located on the equipment cabin connection frame 1, and the inflation end of the gas cylinder 42 is connected to the inflation pipe port 3, and a pressure regulating valve (not shown in the figure) can also be provided between the gas cylinder 42 and the inflation pipe port 3, and the pressure regulating valve is used to adjust the inflation pressure of the gas in the gas cylinder 42 entering the inflation rubber tube 2. Further, a pressure sensor (not shown in the figure) can also be provided on the gas cylinder 42, and the pressure sensor is used to monitor the gas pressure in the gas cylinder 42 in real time.

[0043] Specifically, the fixing structure 5 includes an upper support plate 51 and a lower support plate 52 which are arranged on the equipment cabin connection frame 1. The upper support plate 51 and the lower support plate 52 are used to clamp the gas cylinder 42 therebetween. At the same time, a strap 53 is also arranged on the equipment cabin connection frame 1. The strap 53 is wrapped around the gas cylinder 42 and is used to fix the gas cylinder 42 between the upper support plate 51 and the lower support plate 52.

[0044] Further explanation: when installing the upper support plate 51 and the lower support plate 52, it is necessary to install angle bars on the equipment cabin connection frame 1, and install two transverse angle bars on the upper and lower sides of the equipment cabin connection frame 1, respectively, to fix the upper support plate 51 and the lower support plate 52 on the equipment cabin connection frame 1 by bolts. At the same time, longitudinal angle bars are installed on both sides of the gas cylinder 42, and the two ends of the binding band 53 are fixed by bolts. The specific installation position of the angle bars can be determined according to the actual installation situation of the gas cylinder 42. At the same time, an embedding groove matching the gas cylinder 42 is also required on the equipment cabin connection frame 1, so that the gas cylinder 42 can be embedded in the embedding groove to further improve the stability of the gas cylinder 42.

[0045] The implementation principle of the sealing structure of the target drone water recovery equipment cabin in the embodiment of the present application is: the gas cylinder 42 is used to easily replenish the inflatable rubber tube 2 at any time, thereby effectively improving the working life of the inflatable rubber tube 2, and at the same time, the gas pressure in the gas cylinder 42 is monitored in real time by the pressure sensor to ensure the safety and controllability of the inflation process. In addition, the pressure regulating valve can be used to adjust the air pressure entering the inflatable rubber tube 2 in real time to avoid the influence of too high or too low pressure on the sealing of the inflatable rubber tube 2.

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
