Bracket for Parachute Recovery UAV Center of Gravity Measurement System

Abstract

The invention discloses a bracket for a gravity center measuring system of a parachute-recovery unmanned aerial vehicle. With the bracket, a technical problem of poor universality of the existing unmanned aerial vehicle gravity center measuring device can be solved. According to the technical scheme, the bracket comprises rollers, leveling support legs, a pedestal, a support frame, a circular plate, a shell, a worm rod, a worm wheel, a hand wheel, a pressure sensor, an inner thread joint, a support rod, a level gauge and a digital vernier caliper. The plane of the pedestal is in a shape like an equilateral triangle; and the leveling support legs and the rollers are installed at the three top points of the pedestal. The support frame is installed on the upper surface of the pedestal; and the circular plate is installed on the support frame. The shell installed on the upper surface of the circular plate coats a worm wheel and worm rod mechanism formed by the worm rod and the worm wheel. A pressing head is installed at a threaded hole at the center of the pressure sensor; and the inner thread joint coats the pressure sensor. The level gauge is placed in a groove formed in the top of the support rod; and the digital vernier caliper is installed on the upper surface of the shell. According to the invention, technical problems that the gravity center measuring device of the parachute-recovery unmanned aerial vehicle can not move conveniently and the level can not be adjusted can be solved; and practicability is high.

Description

Problems solved by technology

[0008] In order to overcome the shortcomings of poor practicability of existing UAV center of gravity measurement devices, the present invention provides a bracket for parachute recovery UAV center of gravity measurement system

The roller solves the problem of inconvenient movement of the parachute recovery UAV center of gravity measurement device. The leveling legs and level make up for the shortcomings of the parachute recovery UAV’s inability to adjust the level. For the problem of human-machine pitch angle, the digital display vernier caliper can accurately and intuitively display the changing height of the support rod, accurately adjust the pitch angle of the drone, and the pressure sensor can accurately measure the gravity of the drone, which is very practical
