Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
Fig. 1 is a schematic overall structure diagram of an embodiment of the present invention. As shown in fig. 1, the connecting device for the stratospheric airship pod in the embodiment of the invention comprises an airship joint 11, a first fastener 12, a first ball joint 13, a second ball joint 15, a second fastener 16 and a pod joint 17. The airship joint 11 is used for connecting an airship body, the nacelle joint 17 is used for connecting a nacelle body, the first fastener 12 is used for connecting the airship joint 11 and the bulb of the first bulb connecting piece 13, the second fastener 16 is used for connecting the nacelle joint 17 and the bulb of the second bulb connecting piece 15, the bulb of the first bulb connecting piece 13 is arranged inside the first fastener 12 in a rotatable manner, the bulb of the second bulb connecting piece 15 is arranged inside the second fastener 16 in a rotatable manner, and the rod part of the first bulb connecting piece 13 and the rod part of the second bulb connecting piece 15 are connected in a mutually pivotable manner.
Further, as shown in fig. 1, the end of the shaft portion of the first ball joint member 13 in the present embodiment has a protruding end, and the end of the shaft portion of the second ball joint member 15 has a recessed portion matching the protruding end. The extension end of the end part of the rod part of the first ball head connecting piece 13 can be inserted into the recessed part of the end part of the rod part of the second ball head connecting piece 15 in a matched mode, the extension end and the recessed part are connected through a rivet 14, and the first ball head connecting piece 13 and the second ball head connecting piece 15 can rotate around the axis of the rivet 14.
In this embodiment, the first ball joint 13 and the second ball joint 15 are connected by a rivet 14, and the first ball joint 13 and the second ball joint 15 can be ensured to rotate relative to each other. Of course, a groove portion may be provided at an end portion of the rod portion of the first ball joint connector 13, an extending end may be provided at an end portion of the rod portion of the second ball joint connector 15, and the first ball joint connector 13 and the second ball joint connector 15 may be connected by a rivet 14 or a connecting pin, so that the first ball joint connector 13 and the second ball joint connector 15 can be ensured to be relatively rotatable after connection.
Further, the airship joint 11 is a connecting flange. The outer circumference of the bottom of the connecting flange is provided with an external thread which can be connected with the first fastening piece 12.
Correspondingly, the first fastener 12 is an outer hexagonal nut. The first fastening member 12 can be coupled to the external thread on the bottom outer circumferential surface of the coupling flange. The ball head of the first ball head connecting piece 13 can be arranged in a space formed by connecting the first fastening piece 12 and the airship joint 11, and the radial size of the ball head of the first ball head connecting piece 13 is larger than the radial size of an opening of the bottom end face of the first fastening piece 12.
During assembly, the shaft of the first ball joint 13 is first inserted through the inner hole of the first fastening member 12 from the top of the first fastening member 12, and then the first fastening member 12 is screwed to the outer thread of the airship joint 11. Since the radial dimension of the ball portion of the first ball joint member 13 is larger than the radial dimension of the opening of the bottom end surface of the first fastener 12, the ball portion of the first ball joint member 13 remains in the space formed by the connection of the first fastener 12 and the airship joint 11 and can rotate freely.
Further, in order to ensure that the ball head of the first ball head connecting piece 13 freely and stably rotates in the space formed by connecting the first fastening piece 12 and the airship joint 11, a V-shaped surface capable of being matched with the ball head of the first ball head connecting piece 13 is arranged on the bottom end surface of the airship joint 11.
Further, an external thread capable of being connected with the second fastening member 16 is provided on the top outer circumferential surface of the pod joint 17.
Correspondingly, the second fastener 16 is an outer hex nut. The second fastening member 16 can be coupled to an external thread on the top outer circumferential surface of the nacelle joint 17. The ball head of the second ball joint 15 can be arranged in a space formed by connecting the second fastener 16 and the pod joint 17, and the radial dimension of the ball head of the second ball joint 15 is larger than the radial dimension of the opening of the bottom end face of the second fastener 16.
During assembly, the shaft of the second ball joint 15 is first inserted through the inner bore of the second fastener 16 from the bottom of the second fastener 16, and the second fastener 16 is then tightened against the outer thread of the pod adapter 17. Since the radial dimension of the ball portion of the second ball joint 15 is larger than the radial dimension of the opening of the bottom end face of the second fastener 16, the ball portion of the second ball joint 15 can be retained in the space formed by the connection of the second fastener 16 and the pod joint 17 and can rotate freely.
Further, in order to ensure that the ball head of the second ball joint 15 freely and smoothly rotates in the space formed by the connection of the second fastener 16 and the pod joint 17, a V-shaped surface capable of being matched with the ball head of the second ball joint 15 is arranged on the top end surface of the pod joint 17.
Further, the first and second fastening members 12 and 16 are each provided with a through hole on their outer surface, which can be used for assembly.
Furthermore, when each component is assembled by using threaded connection, thread sealant needs to be coated on the threads, so that the strength of the threaded connection is further ensured. Meanwhile, when the ball head part of the first ball head connecting piece 13 and the second ball head connecting piece 15 is matched with the V-shaped surface, solid lubricating oil needs to be smeared on the ball head part, so that mutual friction in the rotating process is reduced, and the rotating process of the ball head part and the V-shaped surface is smoother. In order to reduce the influence of the deformation of each component on the connection between the airship and the nacelle, the materials used in the connecting device should be kept as consistent as possible in consideration of the thermal expansion coefficient of each component during the operation of the airship.
By using the connecting device for the airship pod in the stratosphere, the docking of the pod and the airship can be conveniently and reliably completed, and the connecting device can be adapted to the problems of temperature difference change, overpressure expansion of the airship body, inconsistent assembly standards and connection at any curved surface position.
