Steel cable type flight experiment table

Abstract

The invention discloses a steel cable type flight experiment table and belongs to the technical field of plant protection unmanned aerial vehicles. The table comprises a frame body, a flying trolley,a clamp and a ground lifting platform. A friction winch is adopted for closed-loop traction, so through the flying trolley, rapid acceleration and deceleration can be achieved, the track length is shortened and the test section distance is ensured to the greatest degree. Meanwhile, a steel cable replaces the track, so that the structure is simplified. In addition, a ground lifting platform adoptsa hydraulic shear type lifting vehicle to be raised and descend, so the height of a to-be-tested target is adjustable through the lifting vehicle, the complexity of a connection clamp of the flying trolley can be greatly reduced, the structure of the flying trolley is further simplified, and the load of the flying trolley is effectively improved. The steel cable type flight experiment table provided by the invention is more suitable for the actual field operation condition, can simulate the actual operation environment, and can simulate the actual spraying effect under the conditions of simulating different flight heights, speeds and angles of a plant protection unmanned aerial vehicle outdoors.

Description

Technical field [0001] The invention relates to the technical field of plant protection unmanned aerial vehicles, in particular to a steel cable type flying test bench. Background technique [0002] In recent years, due to the rapid development of the plant protection drone industry and lack of standards, there is currently no unified national or industry standard for spraying system testing under the action of its core wind field. Most manufacturers can only accumulate experience through a large number of field spraying operations and use observation fog. The effect of dripping on the leaf surface of plants and improving the spray system. This method is time-consuming and labor-intensive, lacking scientific theoretical support, and limited by the existing technical conditions, it is difficult for plant protection drones to accurately locate the aircraft's altitude and flight line trajectory when flying, resulting in inaccurate experimental test results. The prior art discloses ...

AI Technical Summary

Problems solved by technology

This method is time-consuming and labor-intensive, lacks scientific theoretical support, and is limited by existing technical conditions. When the plant protection drone is flying, it is difficult to accurately locate the height and flight trajectory of the aircraft, resulting in inaccurate experimental test results.

In the prior art, there is disclosed an indoor simulation test platform and method (public number CN104614150A) for plant protection UAV spraying two-phase flow field, which adopts the self-driving form of a vehicle and a trolley, and has complex structure, heavy weight, and complicated connection fixtures. Insensitive to acceleration and deceleration, long track distance required, etc.
