Fixed connection device and aerostat

Abstract

The invention discloses a fixing and connecting device for a floating machine and the floating machine equipped with the fixing and connecting device. The fixing and connecting device can connect external parts to a capsule body of the floating machine. The fixing and connecting device is characterized in that the fixing and connecting device comprises an outer side flange arranged on the outer side of the capsule body, an inner side flange arranged on the inner side of the capsule body, and a connecting part which is used for being connected with the external parts and located on the outer side of the outer side flange; the outer side flange is connected with the inner side flange through a flange connecting bolt, a boss which is used for containing the head portion of the flange connecting bolt is located on the lower end face, deviating from the outer side flange, of the inner side flange, a containing space is formed between the upper end face, deviating from the inner side flange,of the outer side flange and the connecting part, and the containing space is used for containing the thread part of the flange connecting bolt and covering the thread part.

Description

technical field [0001] The invention relates to the technical field of aerostats, in particular to a fixed connection device for an aerostat and an aerostat equipped with the fixed connection device. Background technique [0002] Rigid structural fixed connectors have the advantages of high strength, acid and alkali resistance, and convenient processing, and are widely used in the connection of aerostat capsule parts. The current rigid fixed connectors are connected to the capsule body and parts through fasteners. The structural edges and corners of the fasteners used in large quantities are easy to scratch the capsule body, affecting the seal of the aerostat and the mechanical properties of the capsule material, which cannot meet the requirements of the aerostat. The experimental requirements of the aerostat capsule; and for the aerostat with large size and large load, the flaw detection of the aerostat capsule during the ground test is not easy to operate, so it is necessa...

Problems solved by technology

The current rigid fixed connectors are connected to the capsule body and parts through fasteners. The structural edges and corners of the fasteners used in large quantities are easy to scratch the capsule body, affecting the seal of the aerostat and the mechanical properties of the capsule material, which cannot meet the requirements of the aerostat. The experimental requirements of the aerostat capsule; and for the aerostat with large size and large load, the flaw detection of the aerostat capsule during the ground test is not easy to operate, so it is necessary to conduct research on the capsule protection that affects the aerostat seal strict quality control

The existing capsule protection method uses flexible material wrapping or attachment bonding for process protection, which not only increases the load of the aerostat, increases the assembly process, and prolongs the assembly operation time, but also the connection of the protective parts is unreliable and easy to fall off, resulting in floating Due to the damage of the capsule during the ground test, the ideal protection effect cannot be achieved.
