Description

Technical Field

[0001] The present application relates to the field of target drones, and in particular to an integrated safety valve structure of a target drone. Background Art

[0002] In the aerospace field, safety valves are key components to ensure the safe operation of aircraft and are used to control the pressure of the system. However, traditional safety valves and their installation structures are usually relatively independent in design, requiring separate housings and additional pipes for connection, which not only increases the weight of the fuselage, but also takes up valuable fuselage space.

[0003] At present, the safety valve design commonly used in the aerospace field is an independent shell type, that is, the safety valve shell is fixed to the fuselage frame of the aircraft through screws and other fasteners, and connected to other systems through pipelines. Although this design is technically mature and stable, it is too bulky and complicated when used on small aircraft such as target drones.

[0004] Therefore, there is an urgent need for a safety valve structure to solve the problems of large space occupation, heavy weight and inconvenient installation of the target aircraft oil tank safety valve. Utility Model Content

[0005] In order to effectively solve the problems of large space occupation, heavy weight and inconvenient installation of the target drone oil tank safety valve, the present application provides a target drone integrated safety valve structure.

[0006] The present application provides a target drone integrated safety valve structure, which adopts the following technical solution:

[0007] A target drone integrated safety valve structure comprises a safety valve housing integrally formed with a fuselage frame, wherein a first valve group and a second valve group are respectively fixedly arranged in the safety valve housing, joints of the first valve group and the second valve group are both fixedly arranged outside the safety valve housing, and a plug is fixedly arranged on one side of the safety valve housing.

[0008] By adopting the above technical solution and an integrated structure, the safety valve housing and the fuselage frame are integrally formed, and the first valve group and the second valve group are arranged in the safety valve housing, thereby reducing the space occupied by the fuselage frame and the safety valve, thereby saving fuselage space and facilitating the installation of larger equipment. At the same time, there is no need to configure a fixed installation structure for the safety valve separately, thereby reducing the number of fuselage parts.

[0009] Preferably, two mounting holes are provided on the safety valve housing, and the first valve group and the second valve group are respectively threadedly connected to the corresponding mounting holes.

[0010] By adopting the above technical solution and using a threaded connection method, the number of parts of the fuselage is reduced, the space occupied by the safety valve is further reduced, and the weight of the safety valve structure is reduced.

[0011] Preferably, the surface of the safety valve housing is streamlined, and the safety valve housing occupies 1 / 20 of the fuselage frame.

[0012] By adopting the above technical solution, the streamlined structure can be more suitable for flight and effectively reduce the resistance caused by the safety valve housing to flight.

[0013] Preferably, the edges and corners of the safety valve housing are all in the form of arc transitions.

[0014] By adopting the above technical solution, the ability of the safety valve housing to adapt to flight is further improved.

[0015] Preferably, the first valve group includes a first valve body threadedly connected to the mounting hole, a sealing gasket is arranged between the first valve body and the surface of the mounting hole, and a first joint is arranged at one end of the first valve body away from the safety valve housing, and the first joint is located outside the safety valve housing.

[0016] By adopting the above technical solution, the threaded connection between the first valve body and the mounting hole is used to effectively reduce the number of mounting parts when the first valve body is installed, reduce the space occupied and the weight of the entire structure, and facilitate installation. At the same time, the sealing gasket is used to effectively improve the sealing between the first valve body and the safety valve housing.

[0017] Preferably, the second valve group includes a second valve body threadedly connected to the mounting hole, the second valve body and the mounting hole surface are provided with adjusting gaskets, and the second valve body is provided with a second joint at one end away from the safety valve housing, and the second joint is located outside the safety valve housing.

[0018] By adopting the above technical solution, the threaded connection between the second valve body and the mounting hole is utilized, which effectively reduces the number of mounting parts when the second valve body is installed, reduces the space occupied and the weight of the entire structure, and facilitates installation. At the same time, the position of the second joint can be adjusted by adjusting the thickness of the adjusting gasket, thereby improving the adaptability of the second valve group.

[0019] Preferably, the first valve group and the second valve group are staggeredly arranged in the safety valve housing.

[0020] By adopting the above technical solution and the staggered arrangement, the pipeline connected to the first valve group is arranged longitudinally, and the pipeline connected to the second valve group is arranged transversely, which effectively avoids the local structure density caused by the stacking of the two valve groups.

[0021] Preferably, the safety valve housing is made of carbon fiber composite material.

[0022] By adopting the above technical solution, the carbon fiber composite material has the characteristics of high strength, light weight, corrosion resistance, and high and low temperature resistance, which can effectively reduce the mass of the safety valve housing while ensuring that it is not damaged during flight.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. By adopting an integrated molding structure, the safety valve housing and the fuselage frame are integrally molded, and the first valve group and the second valve group are arranged in the safety valve housing, which reduces the space occupied by the fuselage frame and the safety valve, thereby saving fuselage space and facilitating the installation of larger equipment. At the same time, there is no need to configure a fixed installation structure for the safety valve separately, reducing the number of fuselage parts;

[0025] 2. The threaded connection method is used to reduce the number of parts of the fuselage, further reduce the space occupied by the safety valve, and reduce the weight of the safety valve structure;

[0026] 3. The streamlined structure makes it more suitable for flight and effectively reduces the resistance of the safety valve housing to flight;

[0027] 4. By adopting the staggered arrangement, the pipeline connected to the first valve group is arranged longitudinally, and the pipeline connected to the second valve group is arranged transversely, which effectively avoids the local structure density caused by the stacking of the two valve groups.

[0031] The present application is further described in detail below in conjunction with the accompanying drawings.

[0032] The embodiment of the present application discloses a target drone integrated safety valve structure.

[0033] Reference Figure 1The integrated safety valve structure of the target drone includes a safety valve housing 2 integrally formed with a fuselage frame 1, and two mounting holes 6 are provided on the safety valve housing 2, wherein a first valve group 3 is provided in one mounting hole 6, and a second valve group 4 is provided in the other mounting hole 6, and a plug 5 is provided on one side of the safety valve housing 2. The first valve group 3 is connected to the first pipeline, and the second valve group 4 is connected to the second pipeline.

[0034] Specifically, in this embodiment, the surface of the safety valve housing 2 can be streamlined (not shown in the figure), and the edges and corners of the safety valve housing 2 can adopt an arc transition method. The streamlined structure can be more suitable for flight and effectively reduce the resistance caused by the safety valve housing 2 to flight. Further explanation, in this embodiment, the safety valve housing 2 occupies about 1 / 20 of the fuselage frame 1, which effectively reduces the proportion of the safety valve housing 2 occupying the fuselage frame 1, thereby reducing the space occupied by the safety valve.

[0035] It should also be noted that the safety valve housing 2 is an L-shaped structure, and the two mounting holes 6 are arranged in a highly staggered manner, so that the first pipeline is arranged longitudinally and the second pipeline is arranged transversely, effectively avoiding the problem of local structure density caused by the staggering between the first pipeline and the second pipeline.

[0036] Reference Figure 2 The first valve group 3 includes a first valve body 31 threadedly connected to a mounting hole 6, and a sealing gasket 32 ​​is arranged between the first valve body 31 and the mounting hole 6. The sealing gasket 32 ​​effectively improves the sealing performance between the first valve body 31 and the safety valve housing 2. A first joint 33 is arranged at one end of the first valve body 31 away from the safety valve housing 2, and the first joint 33 is located outside the safety valve housing 2. A first valve core is arranged in the first valve body 31, and a first spring (not shown in the figure) is inserted in the first valve core.

[0037] Reference Figure 2 The second valve group 4 includes a second valve body 41 threadedly connected to another mounting hole 6, an adjusting gasket 42 is arranged between the second valve body 41 and the mounting hole 6, and a second joint 43 is arranged at one end of the second valve body 41 away from the safety valve housing 2, and the second joint 43 is located outside the safety valve housing 2. By changing the thickness of the adjusting gasket 42, the position of the second joint 43 is effectively adjusted to improve the adaptability of the second valve group 4. A second valve core is arranged in the second valve body 41, and a second spring (not shown in the figure) is inserted in the second valve core.

[0038] The implementation principle of the integrated safety valve structure of the target drone in the embodiment of the present application is as follows: adopting an integrated structure, the safety valve housing 2 and the fuselage frame 1 are integrally formed, and the first valve group 3 and the second valve group 4 are arranged in the safety valve housing 2, thereby reducing the space occupied by the fuselage frame 1 and the safety valve, thereby saving fuselage space and facilitating the installation of larger equipment. At the same time, there is no need to configure a fixed installation structure for the safety valve separately, thereby reducing the number of fuselage parts.
