Description

Technical Field

[0001] The utility model relates to the technical field of spectral information acquisition, in particular to a multi-angle and multi-blade spectral information acquisition device. Background Technique

[0002] Spectral information acquisition technology has important application values in fields such as agricultural monitoring, environmental analysis, and industrial detection. Traditional spectral acquisition devices mostly use fixed probes or single-angle adjustment structures for data acquisition, and there are significant defects in practical applications:

[0003] 1. Limited angle adjustment: Existing devices mostly achieve single-dimensional angle changes by manually adjusting the elevation angle of the probe, and it is difficult to achieve synchronous multi-angle acquisition of the blade space. When multi-directional reflectance analysis is required for targets such as plant canopies and complex curved surfaces, the integrity of the data is easily restricted by the singularity of the acquisition angle;

[0004] 2. Low degree of automation: Devices using mechanical buckles or screw adjustments require frequent manual intervention. Especially when continuous acquisition at multiple points is carried out, the operation efficiency is low and human errors are easily introduced, making it difficult to meet the requirements of large-scale dynamic monitoring;

[0005] 3. Insufficient structural stability: Some adjustable devices use multi-layer cantilever structures to achieve angle adjustment, and there are problems such as redundant transmission components and cumulative mechanical clearances, resulting in easy offset vibration of the blade mounting plate during long-term use, affecting the accuracy of spectral data. Content of the Utility Model

[0006] In order to overcome the above problems, the utility model constructs a spectral acquisition system with three-degree-of-freedom collaborative adjustment ability through the innovative combination of a modular transmission structure and a spatial linkage mechanism.

[0008] As an improvement, the disc-shaped mounting frame body includes a mounting disc, a main shaft passing through the mounting disc is fixedly installed at the center of the mounting disc axis, a first gear shaft sleeve is rotatably connected to the main shaft, a first connecting rod is fixedly connected to the upper end of the first gear shaft sleeve, and a first arc-shaped rod is rotatably connected to the bottom end of the first connecting rod.

[0009] As an improvement, a second gear shaft sleeve is rotatably connected to the outside of the first gear shaft sleeve. A second connecting rod is fixedly connected to the bottom end of the second gear shaft sleeve, and a second arc-shaped rod is rotatably connected to the bottom end of the second connecting rod.

[0010] As an improvement, a third gear shaft sleeve is rotatably connected to the outside of the second gear shaft sleeve. A third connecting rod is fixedly connected to the bottom end of the third gear shaft sleeve, and a third arc-shaped rod is rotatably connected to the bottom end of the third connecting rod.

[0011] As an improvement, the other ends of the first arc-shaped rod, the second arc-shaped rod and the third arc-shaped rod are respectively rotatably connected to a blade mounting disc. The blade mounting disc includes a blade mounting disc body, and a blade mounting groove is provided in the blade mounting disc body.

[0012] As an improvement, the multi-angle adjusting device further includes a first gear shaft, a second gear shaft and a third gear shaft rotatably connected to the mounting disc. The first gear shaft meshes with the first gear shaft sleeve, the second gear shaft meshes with the second gear shaft sleeve, and the third gear shaft meshes with the third gear shaft sleeve.

[0014] As an improvement, the gears of the second gear shaft sleeve and the third gear shaft sleeve are detachably installed on their respective shaft sleeves.

[0015] The advantages of the present utility model compared with the prior art are as follows:

[0016] 1. Three-degree-of-freedom coordinated adjustment ability: Through the concentric nested design of the first gear shaft sleeve, the second gear shaft sleeve and the third gear shaft sleeve, and in cooperation with the linkage mechanism of three arc-shaped rods distributed with a phase difference of 120°, the blade mounting disc body can perform pitch angle adjustment and rotation angle adjustment, and the blade mounting disc body can perform rolling motion during the movement. The acquisition blades embedded in the blade mounting groove can achieve ±45° dynamic inclination adjustment, breaking through the limitation of traditional single-dimensional adjustment and meeting the multi-directional reflectivity analysis requirements of complex curved surfaces;

[0017] 2. Improvement in maintenance convenience: The disc-shaped bottom support and the mounting frame body adopt a split design, and vulnerable parts such as driving motors and gear shafts can be independently disassembled and replaced; the detachable connection structure between the conical cover body and the device cylinder body is convenient for spectrometer calibration and optical window cleaning and maintenance.

A third gear shaft sleeve 604 is rotatably connected to the outside of the second gear shaft sleeve 605;

[0030] The upper end of the first gear shaft sleeve 606 is fixedly connected to a first connecting rod 609. The bottom end of the second gear shaft sleeve 605 is fixedly connected to a second connecting rod 608. The bottom end of the third gear shaft sleeve 604 is fixedly connected to a third connecting rod 607. The bottom end of the first connecting rod 609 is rotatably connected to a first arc-shaped rod 611. The bottom end of the second connecting rod 608 is rotatably connected to a second arc-shaped rod 610. The bottom end of the third connecting rod 607 is rotatably connected to a third arc-shaped rod 612;

[0031] The other ends of the first arc-shaped rod 611, the second arc-shaped rod 610, and the third arc-shaped rod 612 are respectively rotatably connected to the blade mounting disc 7. The blade mounting disc 7 includes a blade mounting disc body 701. A blade mounting groove 702 is provided inside the blade mounting disc body 701.
