Description

Technical Field

[0001] The utility model relates to the technical field of pod balancing, in particular to a device for determining the counterweight of a small or medium-sized spherical pod. Background Art

[0002] The lower or front part of the fuselage of drones and helicopters is usually equipped with an optoelectronic pod, which is integrated with various optoelectronic sensors for multi-angle dynamic target search and tracking. Small and medium-sized airborne spherical pods are usually installed on aircraft through damping devices. Due to the misalignment of the center of mass of the pod as a whole and the azimuth rotation axis and the overall mass imbalance, mass imbalance torque and different additional interference torques will be generated during the rotation of the azimuth rotation axis. When the carrier aircraft carrying the pod has high-frequency vibration, the interference torque caused by mass imbalance will convert the linear vibration of the carrier aircraft into angular motion, seriously affecting the various performance indicators of the spherical pod. Therefore, the pod must be strictly balanced as a whole to eliminate the interference torque caused by mass imbalance.

[0003] During the pod design stage, the center of mass should be made to coincide with the azimuth rotation axis as much as possible. However, due to size limitations, inaccurate center of mass of subassemblies in the pod frame and other factors, it is difficult to make the overall center of mass of the pod coincide with the azimuth rotation axis. Therefore, the center of mass balancing is still required after the physical product is made.

[0004] The existing center of mass balancing method usually adopts the method of installing a counterweight block in the pod, but due to the difference in production quality and product model, the position of the counterweight of each pod is different. Utility Model Content

[0031] An embodiment of the present application provides a device for determining the counterweight of a small and medium-sized spherical pod, comprising: a mounting bracket 100; two first rotating axis brackets 200, the two first rotating axis brackets 200 being relatively arranged on both sides of the top of the mounting bracket 100; a second rotating axis bracket 300, connected to the first rotating axis bracket 200 via a first rotating axis system 400; a pod mounting plate 500, connected to the second rotating axis bracket 300 via a second rotating axis system 600, a spherical pod 700 being installed in the middle of the pod mounting plate 500, the spherical pod 700 being fixed on the pod mounting plate 500 and being arranged in the mounting bracket 100.

[0032] The following describes a device for determining the counterweight of a small or medium-sized spherical pod provided in an embodiment of the present disclosure in conjunction with the accompanying drawings.

[0033] Figure 1 The overall structural diagram of the device for determining the weight of a small and medium-sized spherical pod provided in an embodiment of the present application is shown; Figure 2 A schematic diagram of the installation of a small and medium-sized spherical pod counterweight determination device provided in an embodiment of the present application is shown; Figure 3 A top view of a device for determining the counterweight of a small or medium-sized spherical pod provided in an embodiment of the present application is shown; Figure 4 A schematic diagram of the first part of the structure of a device for determining the weight of a small or medium-sized spherical pod provided in an embodiment of the present application is shown; Figure 5 A second structural schematic diagram of the device for determining the counterweight of a small or medium-sized spherical pod provided in an embodiment of the present application is shown.
