Description

Technical Field

[0001] This utility model relates to the field of forestry survey technology, specifically to a portable GNSS positioning and image acquisition device for forestry resource surveys. Background Technology

[0002] Forestry resource survey refers to the systematic investigation, monitoring and evaluation of the quantity, quality, structure, distribution, growth and development status and dynamic changes of forestry resources such as forests, trees, forest land, wild animals and plants, and wetlands in a specific area through scientific technical methods and means. It is the core foundation for scientific forestry management, planning and decision-making, resource protection and rational utilization.

[0003] In forestry surveys, GNSS positioning and image acquisition are core technologies. They address the pain points of traditional forestry surveys, such as "vague positioning, incomplete recording, and low efficiency," from the two dimensions of "precise spatial location anchoring" and "visualized recording of on-site information," respectively, providing irreplaceable basic support for subsequent resource assessment, planning management, and dynamic monitoring.

[0004] When using GNSS positioning devices for forestry surveys, a centering rod is typically connected to the device. To ensure accuracy, the centering rod needs to be vertically inserted into the ground after the coordinates are located. However, existing positioning devices are usually fixedly connected to the centering rod. Forest terrain is generally complex and has a thick layer of fallen leaves and humus, making it difficult to insert the centering rod vertically. Often, even after repeated insertion and removal, the rod remains tilted. This tilted centering rod causes the positioning system to tilt as well, requiring more time for calibration and affecting measurement accuracy. Utility Model Content

[0005] The purpose of this invention is to provide a portable GNSS positioning and image acquisition device for forestry resource surveys, so as to solve the above-mentioned shortcomings in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a portable GNSS positioning and image acquisition device for forestry resource surveys, comprising a first rod body, a second rod body threadedly connected to the first rod body; a truncated cone fixedly disposed at the top of the second rod body, a ball head fixedly disposed at the top of the truncated cone, a ball head seat ball-jointed to the ball head, a balance disc fixedly disposed on the side of the ball head seat away from the ball head, four balance plates rotatably disposed on the outer circumference of the balance disc, a counterweight ball disposed at the end of each balance plate away from the balance disc, and an acquisition mechanism disposed on the balance plate.

[0007] Preferably, each of the balance plates has a pull rope fixedly installed at the end away from the balance disc, and the end of each pull rope away from the balance plate is fixedly connected to each of the counterweight balls in a one-to-one correspondence.

Detailed Implementation

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] Please see Figure 1-5 A portable GNSS positioning and image acquisition device for forestry resource surveys is disclosed. The proposed technical solution includes a first rod 1, with a second rod 3 threadedly connected to the first rod 1. A frustum 7 is fixedly mounted on the top of the second rod 3, and a ball head 10 is fixedly mounted on the top of the frustum 7. A ball head seat 11 is ball-jointed to the ball head 10. A balance disc 12 is fixedly mounted on one side of the ball head seat 11 away from the ball head 10. Four balance plates 13 are rotatably mounted on the outer circumference of the balance disc 12. Each balance plate 13 has a counterweight ball 16 at its end away from the balance disc 12. An acquisition mechanism 2 is also mounted on the balance plate 13. The first rod 1 and the second rod 3 are threadedly connected, allowing the first rod 1 and the second rod 3 to be separated when not in use for easy carrying. The frustum 7 is used to fix the ball head 10 without obstructing the rotation of the balance plates 13. The balance plate 13 is rotatably connected to the balance disk 12. Initially, each balance plate 13 is retracted onto the second rod 3, and the balance plate 13 and the second rod 3 are fixedly connected. In use, the first rod 1 is forcefully inserted into the ground, and then each balance plate 13 is rotated to be flush with the balance disk 12. At this time, the counterweight balls 16 on each balance plate 13 pull each balance plate 13 downward. If the first rod 1 is not inserted vertically, the balance disk 12 gradually becomes horizontal with the cooperation of the ball head 10 and the ball head seat 11 (the principle is similar to a seesaw). When the balance plate 13 stops swinging, the balance disk 12 is fixed. At this time, the acquisition mechanism 2 on the balance disk 12 is close to horizontal, instead of tilting like the first rod 1 and the second rod 3, which greatly saves calibration time, can adapt to more terrains, and increases the accuracy of measurement.

[0024] Specifically, each balance plate 13 has a pull rope 15 fixedly installed at the end away from the balance disk 12, and the end of each pull rope 15 away from the balance plate 13 is fixedly connected to each corresponding counterweight ball 16; when the second rod 3 is tilted, the suspended counterweight ball 16 can swing under the action of gravity by means of the mobility of the pull rope 15, and adjust its position by its own swing, so that the balance disk 12 remains horizontal to a certain extent. The acquisition mechanism 2 is detachably connected to the balance disk 12. The acquisition mechanism 2 integrates a GNSS positioning module and an image acquisition module, and is also equipped with power supply and other components. This is existing technology and will not be described in detail. When inserting the first rod 1, the acquisition mechanism 2 can be removed first, and then installed after the balance plate 13 is horizontal, to prevent the uneven weight distribution inside the acquisition mechanism 2 from affecting the horizontality of the balance disk 12.

[0025] Specifically, four sliders 21 are slidably mounted on the balance disk 12. Each slider 21 is fixedly mounted with a second spring 22 between it and the balance disk 12. Each slider 21 is fixedly mounted with a push plate 20. Each balance plate 13 has a protruding tail. Each slider 21 is aligned with the corresponding balance plate 13. When the balance plate 13 rotates, it will squeeze the slider 21 to make it move. The end of the slider 21 is semi-circular. When the balance plate 13 is parallel to the balance disk 12, the balance plate 13 separates from the slider 21. The second spring 22 makes the slider 21 return to its original position. The bottom of the slider 21 abuts against the balance plate 13. The balance plate 13 can no longer rotate downwards. Pushing the push plate 20 makes the slider 21 retract, so that the slider 21 separates from the balance plate 13. The balance plate 13 flips downwards under the action of gravity.

[0026] Specifically, the second rod 3 has a storage slot 17 that is adapted to the balance plate 13; each balance plate 13 is an arc-shaped plate, and after the balance plate 13 is rotated downward, it will fit against the inner wall of the storage slot 17. At this time, the outer side of the balance plate 13 is flush with the outer circumference of the second rod 3.

[0027] Specifically, each balance plate 13 has a groove 14, and each storage slot 17 has a positioning protrusion 18 that matches the groove 14. When the balance plate 13 rotates into the storage slot 17, each positioning protrusion 18 is engaged in the corresponding groove 14. At this time, the balance plate 13 cannot move, and the balance disc 12 will not rotate. The outer circumferential surface of the second rod body 3 also has a concave hole 19 for storing the counterweight ball 16.

[0028] Specifically, a fixing ring 4 is fixedly installed on the outer circumference of the second rod body 3, and a first spring 5 is fixedly installed on the fixing ring 4. A protective sleeve 6 is fixedly installed at the end of the first spring 5 away from the fixing ring 4. The protective sleeve 6 is slidably connected to the second rod body 3. In the initial state, the counterweight ball 16 is stored in the concave hole 19, and the balance plate 13 is stored in the storage groove 17. At this time, the protective sleeve 6 covers the balance plate 13. When the balance plate 13 needs to be used, the protective sleeve 6 is pushed down to expose each balance plate 13. Then, each balance plate 13 is rotated. When storing the balance plate 13, the protective sleeve 6 is pushed down to expose the storage groove 17. After storage, the protective sleeve 6 is released and the first spring 5 is used to reset the protective sleeve 6.

[0029] Specifically, a fixing frame 8 is fixedly installed on the cone 7, and a bolt 9 is threadedly connected to the fixing frame 8; the bolt 9 is aligned with the spherical shell of the ball head seat 11. When the balance disk 12 is nearly horizontal and no longer swings, the balance disk 12 is fixed by hand, and then the bolt 9 is rotated. The bolt 9 is tightly abutted against the ball head seat 11, so that the ball head seat 11 cannot rotate, and the balance disk 12 is fixed in a nearly horizontal position. The weight and shape of the same type of parts at different positions on the balance disk 12 are the same, and the various parts on the balance disk 12 are evenly distributed. After the acquisition mechanism 2 has collected the position information, the image acquisition module on the acquisition mechanism 2 collects the image data.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
