Description

Technical Field

[0001] The utility model belongs to the technical field of sonar buoy pods, and particularly relates to a safety mechanism for a sonar buoy pod. Background Art

[0002] A sonar buoy is launched from an aircraft via a sonar buoy pod. During takeoff and landing, the vibration and impact of the aircraft may cause the structure inside the pod that locks the buoy to fail, causing the sonar buoy to fall off the pod, endangering flight safety. Therefore, a safety mechanism for the sonar buoy pod is designed at the exit of the sonar buoy pod. Existing sonar buoy pods generally have a single safety mechanism, that is, a safety mechanism is only installed inside the pod, and a safety mechanism is not considered to be installed at the exit of the sonar buoy pod. The single safety mechanism is easily misactivated due to vibration, impact, etc. during launch or transportation, resulting in poor safety of the sonar buoy pod and prone to danger. Utility Model Content

[0003] In view of this, the utility model provides a safety mechanism for a sonar buoy pod to solve the problem that the existing sonar buoy pod has poor safety and is prone to danger.

[0004] The technical solution of the utility model is:

[0005] A safety mechanism for a sonar buoy pod is installed between two buoy release guide cylinders of the pod and includes a motor, a support, a turntable, two turntable covers, two cranks, and two push rods. The motor is mounted on the support by screws, the turntable is fixed to the main shaft of the motor, the two cranks are hinged to the turntable, and the two cranks are respectively hinged to the two push rods.

[0006] The motor drives the turntable to rotate, so that the two cranks push the two push rods to move, and the two push rods realize the locking and release of the buoys in the two buoy release guide cylinders.

[0007] Furthermore, the support is fixed between the outlets of the two buoy release guide cylinders;

[0008] The motor is fixedly mounted on the support.

[0009] Furthermore, the turntable is fixedly connected to the main shaft of the motor and has two connecting holes;

[0010] One end of the crank is hinged to the turntable based on the connecting hole, and the other end is hinged to the push rod;

[0011] The crank is arranged perpendicular to the motor main shaft.

[0012] Furthermore, the safety mechanism for the sonar buoy pod also includes two coaxial guide holes, and the two groups of push rods are respectively guided and limited by the two groups of guide holes; after the two groups of push rods extend out of or retract into the two groups of guide holes at one end away from the two groups of cranks, they enter or retract into the two groups of guide cylinders to lock or release the buoys in the two groups of guide cylinders.

[0013] Furthermore, both groups of guide holes are fixedly connected to the support.

[0014] Furthermore, the two groups of guide holes are both linear guide holes, and are both perpendicular to the main shaft of the motor.

[0015] Furthermore, the outlet of the guide hole is configured to fit in a form-fitting manner with the outer shell of the guide tube.

[0016] The beneficial effects of the utility model are:

[0017] The utility model provides a safety mechanism for a sonar buoy pod, which can ensure that the sonar buoy is fixed inside the buoy pod when the internal safety mechanism of the sonar buoy pod fails, thereby fully ensuring safety and reducing the danger of the sonar buoy during storage, transportation and use in the buoy pod.
