Inflating and deflating all-in-one machine for check-in of universal type aerostat

Abstract

The invention relates to an inflating and deflating all-in-one machine for check-in of a universal type aerostat. The inflating and deflating all-in-one machine comprises a sealing cylinder (1), an inflating unit and a deflating unit, wherein a gas inlet, a gas outlet A (2) and a gas outlet B are formed in the sealing cylinder (1); and the inflating unit is mounted on the gas inlet of the sealing cylinder (1), and the deflating unit is mounted on the gas outlet B of the sealing cylinder (1). The inflating and deflating all-in-one machine has the advantages that the inflating and deflating all-in-one machine is compact in size and light in weight; the deflating unit of the all-in-one machine adopts a rotating type mechanical valve which is small in size and light in weight, so that the size and the weight of the all-in-one machine are greatly reduced, the appearance size of the all-in-one machine is only (200*200*200) mm, and the weight of the all-in-one machine is only 2.5kg; and the all-in-one machine is dual-purpose and excellent in performance.

Description

technical field [0001] The invention relates to an aerostat in the field of mechanical equipment, in particular to a general-purpose aerostat check-in integrated machine for charging and deflation. Background technique [0002] The aeroplane is a lighter than air aircraft, relying on the buoyancy generated by the buoyant gas inside the airbag to overcome its own weight to achieve air retention. The aeroplane has the advantages of long air time, good economical use, safety and reliability It is a kind of high-tech product that the world's military powers are vying to develop and develop, and has a very wide range of military and civilian uses. [0003] In addition to performing scheduled flight tasks, the aeroplane is in the daily check-in state most of the time. In this state, the staff only need to manipulate the relevant equipment to control the pressure of the airbag within the predetermined range. According to the existing data, the check-in mode of domestic aerostats u...

Problems solved by technology

According to the existing data, the check-in mode of domestic aerostats under research and production can be divided into two types: one is completed by the ball (boat) equipment equipped with the aerostat itself, and this mode has the function of automatically adjusting the airbag pressure. It only needs the staff to monitor its working status, which can effectively reduce the labor intensity and the probability of misoperation of the staff, but it requires part (or all) of the ball (boat) equipment to work continuously for a long time, causing the aerostat The waste of the effective service life of the ball (boat) equipment and the soaring maintenance cost; the other is to use ground auxiliary equipment, such as using the ground fan and air duct as the aerostat inflation device to inflate (the airbag pressure is low), and Cooperate with the manual opening of the ball (boat) on-board deflation device to deflate (the airbag pressure is too high) to maintain the airbag pressure basically constant. In this mode, the ball (boat) on-board equipment does not need to work, which can avoid the service life of the aerostat The waste and the increase of maintenance cost, but it also greatly increases the labor load of the staff and consumes a lot of human resources, especially when the aerostat is anchored in the wild, the layout position of the ground fan and the air duct must follow the ball ( The dynamic adjustment of the body rotation of the boat) brings a lot of inconvenience to the operator

[0004] Comparing the above two check-in modes, it is obvious that the first working mode has strict requirements on material and financial resources, and is not suitable for long-term check-in of aerostats.

Although the second check-in mode has strong practical significance, the executive devices (deflation equipment, inflatable equipment, etc.) have disadvantages such as large volume and weight, inconvenient operation and control methods, and difficult layout. The requirements for the quality of personnel and personnel are high, so that the advantages of this mode in actual use are not prominent
