Description

Tethering Lock Assembly for Tethering Balloons

technical field

The utility model relates to the field of recovery auxiliary equipment for tethered balloons, in particular to a tethered lock assembly for tethered balloons.

Background technique

The tethered balloon belongs to a kind of aerostat, which utilizes the buoyancy of the gas (helium) in the sphere to achieve floating in the air. Tethered balloon payloads can be used in civil fields such as AIS monitoring, atmospheric environment monitoring, public security and fire monitoring, and wide-area Internet of Things coverage, as well as military fields such as air early warning, electronic countermeasures, technical investigation and monitoring. Regardless of whether it is moored in the air or anchored on the ground, in order to keep the tethered balloon in the air, it is necessary to balance the buoyancy and wind disturbance of the balloon through cables and mooring frames. For this reason, the tethered balloon must be equipped with mooring cables and mooring cables. In the mooring state, the tethering in the air is realized through the mooring cables and the cable retracting device; Cone lock enables ground mooring.

The existing aerostat nose cone locks need to be used in conjunction with the electrical control system. The opening and closing of the lock pin can be realized through the control program. However, due to the addition of proximity switches and action actuators, the structure is complicated and the reliability is reduced. When the electrical system breaks down, it is inconvenient to use manual emergency operations. The existing aerostat nose cone lock also has the problem that the tethered balloon cannot realize free changes in pitch and circumferential rotation.

For example, Chinese patent CN202807088 discloses an aerostat nose cone lock with an induction control mechanism. The aerostat nose cone lock needs to be used in conjunction with an electrical control system. The opening and closing of the lock pin can be realized through the control program, but Because of the addition of a proximity switch and an action actuator, the structure is complicated and the reliability is reduced. When the electrical system breaks down, it is inconvenient to use manual emergency operations.

Chinese patent CN203681862 discloses a lock type aerostat nose cone lock. This solution can only meet the requirement of a single degree of freedom for micro-motion pitching. When the tethered balloon is subjected to instantaneous lateral force, a huge torque is generated, threatening the nose cone lock. structural reliability.

Both of the above two nose cone lock schemes are used in conjunction with the fixed pulley, and it is cumbersome and difficult to replace the wire rope.
