Abstract
Description
Technical Field
[0001] This utility model relates to the field of plant quadrat measurement, and in particular to a portable assembled plant quadrat sampler. Background Technology
[0002] In botanical and forestry scientific surveys, the quadrat method is used to measure plant diversity and statistically analyze information such as dominant species, dominant species, plant species, number of plants, canopy cover, and abundance within a quadrat. Based on the economics and feasibility of sampling, the quadrat method is suitable for surveying and sampling trees, shrubs, and herbaceous plants. The quadrat area varies depending on the type of plant being sampled, but in most cases: herbaceous sampling area < shrub sampling area < tree sampling area. The minimum quadrat area for herbaceous plants is 1m x 1m. A square area of suitable size is enclosed using a quadrat apparatus. Data analysis is then used to summarize and analyze the plant diversity and other characteristics within the quadrat. Existing quadrat samplers generally have large and long frames, making them difficult to carry; their structures are fragmented, making assembly difficult; they use a lot of materials, resulting in high costs; and their field measurement efficiency is low. Furthermore, the graduation lines are prone to wear, affecting the measurement results. Summary of the Invention
[0003] Purpose of the utility model: In order to overcome the shortcomings of the prior art, this utility model discloses a portable assembled plant quadrat sampler.
[0004] Technical solution: The portable assembled plant quadrat sampler disclosed in this utility model is composed of multiple unit frame strips with the same structure connected together; each unit frame strip includes a frame strip body, and one end of the front side and the other end of the back side of the frame strip body are respectively provided with concave and convex structures that can overlap and engage, and one end of the front side of the unit frame strip overlaps with one end of the back side of the adjacent unit frame strip; when connecting, a frame edge structure is first formed by one unit frame strip or by connecting multiple unit frame strips, and the ends of the frame edge structure are sequentially vertically connected to form a frame structure.
[0005] Furthermore, the frame strip body has a protruding post structure at one end of its front side and a groove structure at the other end of its back side, and the protruding post structure and the groove structure can be engaged and disassembled.
[0006] Furthermore, a rubber layer is provided on the outside of the convex pillar structure and inside the groove structure.
[0007] Furthermore, the convex column structure can be a cylindrical column, a square column, or an irregularly shaped column structure.
[0008] Furthermore, the frame body is marked with vertical and parallel position marks corresponding to the concave and convex structure positions.
[0009] Furthermore, the frame body is provided with scale marks.
[0010] Beneficial effects: Compared with the prior art, the advantages of this utility model are: the sampler frame is formed by detachable connection of unit frame strips of unit length, and the size of the frame can be adjusted at will as needed, and the size of the sampler can be intuitively grasped according to the length of the unit frame; since the unit frame strips have a consistent structure, they can be directly stacked and snapped together to form a whole when stored, which is convenient for storage. Attached Figure Description
[0011] Figure 1 This is an overall structural diagram of the present invention in its usage state;
[0012] Figure 2 This is an exploded view of the utility model in use.
[0013] Figure 3 This is a diagram showing the storage state of this utility model. Detailed Implementation
[0014] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.
[0015] like Figure 1 and 2 The portable assembled plant quadrat sampler shown is composed of multiple structurally identical unit frame bars 1 connected together. All of them are made of lightweight carbon fiber material and use 50cm standard frame bars.
[0016] The unit frame 1 includes a frame body 101. One end of the front side and the other end of the back side of the frame body 101 are respectively provided with concave and convex structures that can overlap and engage. One end of the front side of the unit frame 1 overlaps with one end of the back side of the adjacent unit frame 1. When connecting, a frame edge structure is first formed by one unit frame 1 or by connecting multiple unit frame 1s. The ends of the frame edge structure are then connected vertically in sequence to form a frame structure.
[0017] The frame strip body 101 has a protruding post structure 102 on one side of the front and a groove structure 103 on the other side of the back. The protruding post structure 102 and the groove structure 103 can be engaged and disassembled.
[0018] A rubber layer is provided on the outside of the protruding column structure 102 and inside the groove structure 103 to improve the locking effect.
[0019] The convex column structure 102 can be a cylindrical, square, or irregularly shaped column structure. The structure is not limited, as long as it can still be properly engaged after a 90° rotation.
[0020] The frame body 101 is marked with vertical and parallel position marks corresponding to the concave and convex structure positions, which facilitates better assembly of the unit frame 1.
[0021] Under normal circumstances, the size of the sampler can be obtained by the number of unit frame bars 1 on one side. The frame bar body 101 is equipped with scale marks to meet the requirements of higher precision.
[0022] like Figure 3 As shown, when storing, simply stack the unit frame strips 1 one on top of the other to form a whole, which makes it easy to store.
