Description

Technical Field

[0001] The utility model belongs to a fixing device, in particular to a clamping and fixing device for a plant canopy analyzer. Background Art

[0002] The plant canopy analyzer is a plant canopy analysis instrument that can measure leaf area index, average leaf inclination, scattered radiation transmittance, direct radiation transmittance at different solar altitudes, extinction coefficient at different solar altitudes, azimuthal distribution of leaf area density, photosynthetically active radiation inside and outside the canopy, etc. It is widely used in the measurement and analysis of the light conditions of the canopy of crops and plant groups, as well as in agricultural and forestry scientific research.

[0003] At present, most of the existing plant canopy analyzers are handheld, and workers walk in the field holding the instrument to collect data information. This method of use requires continuous human participation when measuring large areas, and when measuring different heights of the canopy, manual adjustment is prone to measurement errors due to subjective factors. In response to the above problems, the publication number is CN204165577U, and the name is AccuPAR Plant Canopy Analyzer External PAR Sensor Retractable Bracket, which discloses that the device is fixed to the ground by using a base made of an audio-technica, and the height of the PAR sensor is adjusted by using a retractable bracket, and then the position of the PAR sensor is adjusted by using a rotating clamp to ensure the accuracy of the data. It solves the above problems to a certain extent; however, in actual use, after the data collection at a certain location is completed, it is still necessary to manually move the device to the next data collection location for positioning, which is relatively troublesome to use, not only inefficient, but also increases labor costs and the labor intensity of the operator. Summary of the invention

[0004] In view of the above-mentioned deficiencies in the prior art, the utility model provides a clamping and fixing device for a plant canopy analyzer.

[0005] The utility model discloses a clamping and fixing device for a plant canopy analyzer, comprising a U-shaped fixing frame, wherein the bottom plate of the U-shaped fixing frame is rotatably connected to a mounting plate on the outside, two clamping members are fixed to the lower part of the outer side surface of the mounting plate, sleeves are fixed inside the two clamping members, internal threads are provided in the sleeves, and the canopy analyzer PAR is connected thereto, and a fisheye camera is fixed to the bottom end of the canopy analyzer PAR.

[0006] As a further improvement of the utility model, two limit blocks are symmetrically fixed to the outside of the bottom plate of the U-shaped fixing frame, and two semicircular slide grooves are provided on the upper part of the mounting plate, and the limit blocks are respectively placed in the slide grooves for use therewith.

[0007] As a further improvement of the present invention, an anti-slip rubber pad is provided on the inner wall of the slide groove.

[0008] As a further improvement of the utility model, a knob is fixed on the top of the canopy analyzer PAR, and anti-slip grooves are arranged around the outer wall of the knob.

[0009] The plant canopy analyzer clamping and fixing device of the utility model has a reasonable structural design and is easy to operate. It is fixed on the front end of the walking device, and the height of the canopy analyzer PAR is adjusted according to the height of the plant. By clamping it on the walking device instead of manual hand-holding to collect data information, not only the measurement is accurate, but also the labor intensity of workers is reduced, the work efficiency is improved, and large-area measurement can be carried out. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 to Figure 3 It is a schematic diagram of the structure of the utility model at different angles. DETAILED DESCRIPTION

[0011] The utility model discloses a clamping and fixing device for a plant canopy analyzer, comprising a U-shaped fixing frame 1, wherein the U-shaped fixing frame 1 is placed horizontally, and a mounting plate 2 is rotatably connected to the outside of the bottom plate of the U-shaped fixing frame 1, and specifically, two limit blocks 7 are symmetrically fixed to the outside of the U-shaped bottom plate of the U-shaped fixing frame 1, and two symmetrical semicircular slide grooves 8 are arranged on the upper part of the mounting plate 2, and the limit blocks 7 are respectively placed in the slide grooves 8 for use therewith, and an anti-slip rubber pad is arranged on the inner wall of the slide groove 8, and by rotating the mounting plate 2 to make the slide groove 8 slide along the limit blocks 7, the angle of the mounting plate 2 can be changed, thereby adjusting the state of the canopy analyzer PAR5, and the anti-slip rubber pad can play a positioning role.

[0012] Two clamping parts 3 are fixed to the lower part of the outer side surface of the mounting plate 2, and a sleeve 4 is fixed inside the two clamping parts 3. The sleeve 4 is provided with an internal thread and is connected to the canopy analyzer PAR5. An external thread is provided on the upper part of the canopy analyzer PAR5. A knob 9 is fixed to the top of the canopy analyzer PAR5 and a fisheye camera 6 is fixed to the bottom. The outer wall of the knob 9 is provided with anti-slip grooves. The installation height of the fisheye camera 6 can be adjusted arbitrarily by turning the knob 9, and the anti-slip grooves can play an anti-slip role when turning the knob 9.

[0013] The plant canopy analyzer clamping and fixing device of the utility model can be fixed on the frame at the front end of the large walking device by using the U-shaped fixing frame 1, and the height of the fisheye camera 6 can be adjusted by turning the knob 9. After the height adjustment of the fisheye camera 6 is completed, the large walking device can be started to make it walk in the field to measure and analyze various data of a large area of ​​plant canopy; when it is not necessary to measure various data of the plant canopy, the canopy analyzer PAR5 can be adjusted to a horizontal state by rotating the mounting plate 2, which will not affect the operation of other equipment.
