Description

Technical Field

[0001] The utility model relates to the field of three-dimensional green quantity observation, and more specifically, to a three-dimensional green quantity observation device for urban green spaces. Background Art

[0002] Urban green spaces are an important part of a city and have various meanings and functions. They can improve air quality, regulate the climate, conserve water and soil, and provide spaces for leisure and entertainment. Among them, the three-dimensional green quantity of a city is an important indicator for measuring the quality of urban greening and ecological benefits. It mainly refers to the spatial volume occupied by the stems and leaves of all plants. Compared with traditional two-dimensional greening indicators (such as green area), it can more accurately reflect the actual ecological functions of urban greening.

[0003] At present, there are various measurement methods for the three-dimensional green quantity of a city. The appropriate measurement method is selected according to different environments. When observing a relatively complex forest environment, lidar technology is mostly used. By manually walking through the forest and performing lidar scanning on the forest to establish a three-dimensional model and then calculate the green quantity. Since the roads in the forest are relatively complex, lidar scanning can only be carried out by manually holding the scanner. Holding the scanner for a long time will cause the observer's arm to ache, increasing the labor intensity. At the same time, it is impossible to maintain the scanning height, which will affect the scanning accuracy. Content of the Utility Model

[0022] Embodiment:

[0023] Please refer to Figures 1-3As shown in the figure, a three-dimensional green quantity observation device for urban green spaces includes a laser scanning observation instrument 1, a support mechanism 2, and a wearing mechanism 3. The support mechanism 2 is placed on the front side of the wearing mechanism 3. The wearing mechanism 3 includes a back plate 301 and a front plate 302. On the front side of the front plate 302, front support rods 305 are symmetrically arranged. The front support rods 305 extend forward in a suspended manner, and the two front support rods 305 are arranged parallel to each other. The support mechanism 2 includes an arc-shaped plate 201. The center of the arc-shaped plate 201 is placed at the rear side, so that the arc-shaped plate 201 can form a semi-surrounding structure on the front side of the user. The arc-shaped plate 201 is fixed at the front ends of the two front support rods 305. A track groove 202 is opened on the inner side of the arc-shaped plate 201. A slider 203 is slidably installed on the surface of the arc-shaped plate 201. The cross-section of the slider 203 is in an I shape. The I-shaped structure can ensure that the slider 203 can only slide along the track of the track groove 202 to ensure its stability after movement. A column 204 is vertically fixed on the top of the slider 203. An adjustment rod 205 is installed on the top of the column 204. A limit plate 206 is arranged on the surface of the adjustment rod 205. A fixing bolt 207 is arranged on the upper surface of the limit plate 206. The diameter of the limit plate 206 is larger than that of the fixing bolt 207, and a threaded surface is arranged above the surface of the fixing bolt 207. The laser scanning observation instrument 1 includes a body 101. A handle 102 is arranged at the bottom of the body 101. A rotary scanning head 103 is rotatably installed on the front side of the body 101. A data docking hole 104 is arranged on one side of the body 101 and is equipped with a power supply. During use, the power supply is connected to the body 101, and through the rotation of the rotary scanning head 103, multi-directional scanning work is realized. A bottom plate 105 is installed at the bottom of the handle 102. The bottom plate 105 extends forward and is horizontally arranged. After use, the laser scanning observation instrument 1 can be placed on the desktop through the bottom plate 105 to facilitate data transmission. A through hole 106 is opened on the front side of the surface of the bottom plate 105. The fixing bolt 207 passes through the through hole 106. A locking nut 4 is screwed on the top of the fixing bolt 207. The locking nut 4 is placed above the bottom plate 105, and the lower surface of the bottom plate 105 is supported by the limit plate 206. By tightening the locking nut 4, the bottom plate 105 is squeezed, thereby maintaining the stability of the laser scanning observation instrument 1 after being installed on the support mechanism 2.

[0024] Among them, when the laser scanning observation instrument 1 is started, it rotates through the rotary scanning head 103 on the front side, emits laser pulses at multiple angles, and simultaneously receives reflection signals, accurately measures the three-dimensional structure of the vegetation, stores the scanning data, and after the observation is completed, the data of the scanner is poured into the computer, thereby calculating the green quantity.

[0025] Please refer to Figure 3 and Figure 4As shown, symmetrically arranged below the outer surface of the fixing bolt 207 are limiting bumps 208. The top of the limiting bump 208 is beveled. Symmetrically provided on the inner wall of the through hole 106 are limiting grooves 107. The limiting bump 208 is adapted to the limiting groove 107. When the bottom plate 105 is installed on the fixing bolt 207, the limiting bump 208 and the limiting groove 107 are engaged to prevent the laser scanning theodolite 1 from rotating during movement, thereby ensuring the stability of the laser scanning theodolite 1.

[0026] Please refer to Figure 4 As shown, a fixed pin 210 is inserted and removed above one side of the column 204. Symmetrically arranged on one side surface of the adjusting rod 205 are positioning holes 209. The end of the fixed pin 210 is adapted to the internal dimension of the positioning hole 209 to adjust the height of the laser scanning theodolite 1 through the adjusting rod 205, thereby adapting to different working environments.

[0027] Please refer to Figure 1 As shown, fixing rings are provided on both sides of the back plate 301 and the front plate 302. A side tightening belt 303 is connected between two fixing rings on the same side. And symmetrically connected to the top of the back plate 301 and the front plate 302 are shoulder straps 304, thereby realizing wearing. The lengths of the side tightening belt 303 and the shoulder straps 304 can be freely adjusted and adjusted according to the user's body type to ensure the stability of the wearing mechanism 3 and prevent shaking during hiking observation. And a buckle is provided at the middle part of the two side tightening belts 303 to improve the convenience during wearing.

[0028] Please refer to Figure 1 and Figure 2 As shown, above the connection between the front support rod 305 and the front plate 302 is provided a reinforcing inclined support rod 306 to improve the strength of the front support rod 305 and the front plate 302 through the reinforcing inclined support rod 306.

[0029] Working principle: Wear the wearing mechanism 3 by means of the buckle in the middle of the side tightening belt 303 and tighten it, so that the back plate 301 is closely attached to the back of the wearer, the front plate 302 is closely attached to the abdomen of the wearer, and the front support rod 305 is suspended forward to ensure the stability of the support mechanism 2. The arc plate 201 is of an arc structure and is placed on the front side of the wearer. Since the slider 203 is in an I shape, the slider 203 can only slide along the arc track of the track groove 202, and then adjust the position of the laser scanning observator 1. Then install the laser scanning observator 1 on the fixing bolt 207 and tighten it through the locking nut 4 to keep the laser scanning observator 1 fixed. At this time, the bottom plate 105 is supported by the limiting plate 206, and the height of the laser scanning observator 1 can be adjusted by sliding the adjusting rod 205. Then the height is fixed through the cooperation of the fixed pin 210 and the positioning hole 209. At this time, hold the handle 102 to control the position of the laser scanning observator 1, so that the rotating scanning head 103 is always placed on the front side of the wearer and can be placed in different orientations. At this time, the user only needs to control the position of the laser scanning observator 1 and keep it fixed. The arm needs to provide a supporting force to reduce the labor intensity and ensure the stability of the hiking equipment at the same time. Through the rotation of the rotating scanning head 103, multi-directional laser scanning work is realized, and the scanned and observed data is stored.

[0030] The above is only the preferred specific implementation manner of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes, and all should be covered by the protection scope of the present invention.
