Bob-weight device used for airship

Abstract

The invention discloses a bob-weight device used for an airship. The bob-weight device comprises a water tank chamber, wherein a water tank frame is connected in the water tank in a vertical sliding connection way; the lower end of the water tank frame is connected with a water tank; the water tank comprises a water tank bottom plate and a water tank top plate; the water tank top plate is providedwith a first water through hole; the first water through hole is connected with a first water tank water through hole cover; the water tank bottom plate is provided with a second water through hole;the second water through hole is connected with a second water tank water through hole cover; the lower end of the water tank bottom plate is fixedly connected with a third bracket; and a third electric push rod used for driving the second water tank water through hole cover to vertically move is arranged between the third bracket and the second water tank water through hole cover. The bob-weightdevice is provided with a bob-weight water tank chamber, and in addition, the lower end of the bob-weight water tank chamber is provided with a water tank; in addition, the water tank can vertically move, so that when a bob weight is increased, the bob-weight water tank can be simply moved into a bob-weight pool, so that bob-weight water can be quickly added into the bob-weight water tank, and therefore, the labor intensity of the bob weight is lowered.

Description

technical field [0001] The invention relates to an airship counterweight system, in particular to a counterweight device for an airship. Background technique [0002] An airship is a type of aerostat, and it is also an aircraft that uses a gas lighter than air to provide lift. According to different working principles, aerostats can be divided into airships, tethered balloons and hot air balloons, etc. Airships are divided into two types: manned and unmanned. The lift obtained by the airship mainly comes from the gas lighter than air filled inside. Modern airships generally use helium with better safety to provide lift. In addition, the engine or battery installed on the airship provides part of the lift for the airship. The power provided by the engine or the battery is mainly used for the horizontal movement of the airship and the power supply of the on-board equipment, so the airship has better energy-saving performance and less damage to the environment than modern jet ...

AI Technical Summary

Problems solved by technology

[0003] The airship uses the buoyancy provided by the lighter gas to balance the weight of the airship itself and the weight of the airship's load, and reach a balanced state. However, because the airship's load often changes during the use of the airship, it needs to be continuously adjusted every time it takes off. At present, the counterweight of the airship must be adjusted by real-time load, but the existing airship counterweight adjustment system has a complex structure, and the counterweight is usually loaded and unloaded into the airship by manpower or machinery, which is time-consuming and laborious, which is not conducive to the rapid counterweight of the airship.
