Description

Technical Field

[0001] This utility model belongs to the field of measurement equipment technology, and in particular relates to a drone flight measurement device. Background Technology

[0002] Measurement equipment refers to instruments, meters, tools or systems used to detect, measure, observe or record parameters such as physical quantities, chemical quantities, and biological quantities. They are widely used in fields such as industry, scientific research, medical care, and environmental monitoring. UAV flight measurement devices are a new type of measurement equipment, which refers to sensors, instruments and data processing systems mounted on UAVs. They are used for tasks such as aerial data acquisition, mapping, and monitoring, and have the advantages of high efficiency, flexibility and low cost in acquiring high-precision spatial information.

[0003] A measurement drone, disclosed in document CN222292014U, includes a cleaning mechanism with a shock-absorbing mechanism fixedly installed at its bottom. The cleaning mechanism comprises the drone body. In this invention, the transparent cover prevents the measuring instrument from being damaged by collisions or impacts during flight, thus extending its service life and ensuring the smooth execution of measurement tasks. It also prevents contaminants from directly accumulating on the lens surface, causing measurement errors. When a large amount of contaminants appears on the transparent cover surface, an electric telescopic rod drives a cleaning brush to contact the transparent cover. Subsequently, an electric slider drives the cleaning brush to rotate and clean the transparent cover surface. Automatic cleaning improves the cleaning efficiency and effectiveness of the transparent cover. The combination of the locking block and spring allows for convenient and quick replacement of aged or damaged transparent covers.

[0004] However, it still has the following drawbacks in practical use:

[0005] 1. The aforementioned measuring drone has its transparent cover mounted on a fixed ring via a clip, and the structure is installed using the transparent cover. However, during use, since the fixed ring is in a fixed position on the drone body, the positioning of the measurement point during the measurement process depends on the flight of the drone body. However, since the flight of the drone body is difficult to control precisely, the measurement error is relatively large, affecting the accuracy of the measurement.

[0006] 2. The aforementioned measuring drone has a fixed ring installed at the bottom of its main body, and a transparent cover is movably inserted into the inner wall of the fixed ring. The measuring structure is installed through the fixed ring and the transparent cover. However, during use, the measuring structure is greatly affected by the external ambient temperature, and there is no structure to cool the measuring structure, which leads to the measurement accuracy being affected by the large external temperature.

[0007] To address these issues, we provide a UAV flight measurement device. Utility Model Content

[0008] The purpose of this utility model is to provide a UAV flight measurement device, which uses a first threaded rod to drive a first L-shaped frame and a second L-shaped frame to move left and right, thereby positioning the measurement structure on the second L-shaped frame. This solves the problem of inconvenience in locating measurement points in existing devices.

This solves the problem of inconvenience in avoiding the influence of temperature on measurement results in existing devices.
