Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of airships, and particularly relates to a hoop structure for connecting a propulsion bracket and a hull, and a stratospheric airship. Background Technique
[0002] A stratospheric airship is a device that can be suspended in the high altitude of the stratosphere for a long time relying on cutting-edge technology. It has excellent performance such as high flight altitude, large payload, and long flight time. Its platform performance is stable and the technical reliability is strong. It can carry different types of surveillance and detection equipment such as communication and navigation equipment, infrared cameras, and early warning radars, and has important civilian and military values.
[0003] The power system is an important part of the airship. The power system mainly includes an electric motor and a power propeller. In the prior art, the power system needs to be connected to the bottom of the hull through a propulsion bracket. The propulsion bracket mainly adopts a metal structure design and usually includes a plurality of connected rods. Since the stratospheric airship will experience temperature changes during the lifting and lowering process, it is easy to expand due to heat or contract due to cold. If the connection method between the propulsion bracket and the hull cannot effectively absorb the large structural deformation caused by temperature changes, the hull will bear greater internal stress and cause certain damage to it.
[0004] Therefore, it is urgent to propose a hoop structure for connecting a propulsion bracket and a hull, and a stratospheric airship to solve the above problems. Content of the Utility Model

[0032] Figure 1 Schematically shown is a structural schematic diagram of a hoop structure for connecting a propulsion bracket and a hull according to an embodiment of the present invention. As Figure 1 shown, the present invention provides a hoop structure for connecting a propulsion bracket and a hull. The propulsion bracket has a plurality of rods. The hoop structure for connecting the propulsion bracket and the hull in this technical solution includes a connection seat 100 and a lining assembly 200. The connection seat 100 has an installation cavity, and the connection seat 100 is used to connect with the hull; the lining assembly 200 is arranged inside the installation cavity and is slidably connected with the connection seat 100, and the lining assembly 200 is used to sleeved on the rods.
[0033] By using the hoop structure for connecting the propulsion bracket and the hull in this technical solution, when the hull deforms due to external temperature changes, the connection seat 100 moves following the deformation of the airship. Since the connection seat 100 and the lining assembly 200 are slidably connected, when the hull deforms, the connection seat 100 and the lining assembly 200 can move relatively, thus avoiding an increase in the traction force between the rods and the hull. Therefore, the setting of this hoop structure can effectively absorb the deformation of the hull caused by temperature changes, avoid the generation of large internal stresses between the hoop structure and the hull, and thus extend the service life of the overall structure of the stratospheric airship.
[0034] Optionally, the hoop structure is made of a metal material. Optionally, the metal material can be cast iron, stainless steel, aluminum alloy, etc. Making the hoop structure of a metal material is firmly and reliably installed and can adapt to the low-temperature environment at high altitudes.
[0035] Furthermore, Figure 2 Schematically shown is a partial structural schematic diagram of the lining assembly 200 according to an embodiment of the present invention. Figure 3 Schematically shown is another partial structural schematic diagram of the lining assembly 200 according to an embodiment of the present invention. Refer to Figures 1 to 3, the lining assembly 200 includes a first lining 210 and a second lining 220. The first lining 210 and the second lining 220 are spliced to form a socket cavity for the socket rod. It can be understood that the shape of the socket cavity is adapted to the shape of the rod. When the cross-sectional shape of the rod forming the propulsion bracket is circular, the shape of the socket cavity is cylindrical. Therefore, the sides of the first lining 210 and the second lining 220 in contact with the rod are arc-shaped surfaces, so that the first lining 210 and the second lining 220 hold the rod tightly, realizing the connection between the lining assembly 200 and the rod.
[0036] Further, a first sliding portion 211 is connected to the first lining 210, a second sliding portion 221 is connected to the second lining 220. A first sliding groove 1101 is provided at the top of the connecting seat 100, and a second sliding groove 1201 is provided at the bottom of the connecting seat 100. The first sliding portion 211 is slidably connected to the connecting seat 100 through the first sliding groove 1101, and the second sliding portion 221 is slidably connected to the connecting seat 100 through the second sliding groove 1201. It can be understood that the first sliding portion 211 can move in the first sliding groove 1101, the second sliding portion 221 can move in the second sliding groove 1201, and the moving directions of the first sliding portion 211 and the second sliding portion 221 are the same. In this embodiment, the movable direction of the lining assembly 200 is perpendicular to the extending direction of the rod.
[0037] Further, a first damping pad 213 is provided on the side of the first sliding portion 211 facing the connecting seat 100, and a second damping pad 223 is provided on the side of the second sliding portion 221 facing the connecting seat 100. The setting of the damping pad can play a role in buffering and shock absorption, preventing vibrations from damaging the propulsion bracket, the hoop structure or the hull. Optionally, grooves are provided on the side of the first sliding portion 211 facing the connecting seat 100 and on the side of the second sliding portion 221 facing the connecting seat 100, and the first damping pad 213 and the second damping pad 223 are respectively arranged in the grooves. The setting of the grooves can play a role in positioning the damping pads, ensuring reliable installation of the damping pads and the connecting parts. Optionally, the damping pads can be bonded in the grooves or welded to the connecting parts. Optionally, the damping pads are circular gasket structures, and their materials can be stainless steel or high carbon steel. These materials have certain elasticity and have the advantages of high precision, strong tensile strength, good surface finish, toughness and not easy to break.
[0038] Further, Figure 4 The structural schematic diagram of the base 110 according to the embodiment of the present invention is schematically shown. Figure 5 The structural schematic diagram of the top cover 120 according to the embodiment of the present invention is schematically shown. See Figure 1 、 Figure 4 and Figure 5, the connecting seat 100 includes a base 110 and a top cover 120. The base 110 and the top cover 120 are detachably connected. The first chute 1101 is provided on the base 110, and the second chute 1201 is provided on the top cover 120. By detachably connecting the base 110 and the top cover 120, the assembly of the hoop structure and the rod member can be facilitated.
[0039] Further, referring to Figure 1 and Figure 4 , the base 110 includes a bottom plate 111 and two parallel and spaced limiting rods 112. The two ends of the limiting rod 112 are respectively connected to the bottom plate 111. The limiting rod 112 and the bottom plate 111 are spaced apart to form the first chute 1101. The two ends of the first sliding portion 211 are respectively inserted into the first chute 1101. Optionally, through holes for passing bolts are provided on the base 110, and the base 110 is connected to the hull by bolts. In this embodiment, the base 110 is an oval disc structure. In other embodiments, the base 110 can be square, circular, kidney-shaped or other shapes. Optionally, support portions perpendicular to the limiting rod 112 are respectively provided at the two ends of the limiting rod 112, and the bottom of the support portion is connected to the bottom plate 111, so that the first chute 1101 is formed between the limiting rod 112 and the bottom plate 111. Optionally, the extending direction of the limiting rod 112 is perpendicular to the axial direction of the socket cavity formed by the first inner liner 210 and the second inner liner 220, that is, the extending direction of the first chute 1101 is perpendicular to the length direction of the socket cavity formed by the first inner liner 210 and the second inner liner 220.
[0040] Further, the first sliding portion 211 and the first inner liner 210 are connected by a first connecting portion 212. The first connecting portion 212 is located in the space between the two limiting rods 112, and the length of the first connecting portion 212 in the direction perpendicular to the limiting rod 112 is less than the distance between the two limiting rods 112. It can be understood that with this structure, the first inner liner 210 can not only move along the length direction of the first chute 1101, but also move in the direction perpendicular to the length direction of the first chute 1101, so as to provide a certain deformation space for the hoop structure and the hull in two degrees of freedom, effectively reducing the generation of internal stress.
[0041] Further, referring to Figure 1 and Figure 5, the top cover 120 includes two oppositely arranged side plates 121. Each side plate 121 is provided with a second sliding groove 1201, and both ends of the second sliding part 221 are respectively inserted into the second sliding groove 1201. It can be understood that the extending direction of the side plate 121 is the same as that of the limiting rod 112, so that the length direction of the first sliding groove 1101 is the same as that of the second sliding groove 1201. In this embodiment, the two side plates 121 are connected by a top plate 122. In other embodiments, the two side plates 121 can also be connected by a connecting rod. Optionally, the second sliding part 221 is connected to the second inner lining 220 through a second connecting part 222. The length of the second sliding part 221 in the direction perpendicular to the side plate 121 is less than the distance between the two side plates 121, so that the second inner lining 220 can not only move along the length direction of the second sliding groove 1201, but also move in the direction perpendicular to the length direction of the second sliding groove 1201.
[0042] Furthermore, the base 110 is provided with a first extension part 113, and the top cover 120 is provided with a second extension part 123. The first extension part 113 and the second extension part 123 are connected by a connecting piece 130. Exemplarily, the first extension part 113 is connected to the bottom plate 111, and the second extension part 123 is connected to the side plate 121. Optionally, a first extension part 113 is respectively arranged on both sides in the length direction of the socket cavity, and a second extension part 123 is respectively arranged at both ends of each side plate 121. Each first extension part 113 is connected to two second extension parts 123, and the two second extension parts 123 connected to the first extension part 113 are arranged at intervals along the length direction of the socket cavity, so that the first extension part 113 is located in the interval between the two second extension parts 123. The connecting piece 130 passes through the first extension part 113 and the second extension part 123 to realize the connection between the base 110 and the top cover 120. Optionally, the connecting piece 130 can be a bolt.
[0043] Furthermore, this embodiment also provides a stratospheric airship, which includes a hull, a propulsion bracket, a power system, and the above-mentioned hoop structure for connecting the propulsion bracket and the hull. The top of the propulsion bracket is connected to the hull through the hoop structure, and the power system is connected to the bottom of the propulsion bracket. Optionally, the power system includes a motor and a propeller, and the motor is used to drive the propeller to rotate. Optionally, the propulsion bracket is generally in an inverted conical shape, and the top is a square frame formed by connecting four rods. A plurality of hoop structures are sleeved on each rod, and the base 110 of the hoop structure is connected to the hull.
[0044] By adopting the hoop structure provided in this embodiment, when the airship undergoes large structural deformations due to temperature changes, this deformation causes the relative sliding between the inner lining assembly 200 and the connecting seat 100 of the hoop structure, thereby avoiding damage to the hull and the hoop structure due to excessive internal stress.
