Description

Technical Field

[0001] This utility model relates to the technical field of desert plant survey quadrats, specifically a portable quadrats for desert plant surveys. Background Technology

[0002] Overgrazing and climate change can easily damage grassland vegetation in pastoral areas. To effectively collect samples of desertified grasslands in different seasons, it is crucial to provide timely remediation and reduce the rate of desertification. During field environmental surveys, sampling is particularly important for data on the quantity, species, and growth status of plants in desert areas. A common sampling tool is the quadrat, which allows for the random collection of plant samples from the grassland, followed by statistical analysis of the collected data.

[0003] Existing sampling devices typically use hinges to assemble and link multiple boards together. When sampling, the sampling frame can be unfolded and placed on the grass. This sampling method has limitations and is not portable. The multiple boards are of different lengths and are prone to deformation over time.

[0004] Therefore, a portable sampling frame for desert plant surveys is proposed, which is flexible, scalable, and adjustable to make it easier to carry, in order to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a portable quadrature frame for desert plant surveys to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a portable quadrature frame for desert plant surveys, comprising a hinge, wherein the outer wall of the hinge is provided with a quadrature frame;

[0007] An adjustment unit is placed inside the sample frame and extends to the outside of the sample frame. The adjustment unit includes a sliding frame, a first magnetic block, a second magnetic block, and a locking pin. It is used to position and limit the adjusted sliding frame by the locking pin under the constraint of magnetic repulsion.

[0008] The positioning unit is placed at the bottom of the quadrat frame. The positioning unit is used to position the quadrat frame and the sliding frame on the grass. Under the constraints of the hinge, the quadrat frame and the adjustment unit, the quadrat frame and the adjustment unit can be adjusted flexibly and adaptably. Under the constraints of the positioning unit, the quadrat frame and the adjustment unit can be stably placed on the grass to avoid displacement during use, which would affect the accuracy of the sample data.

[0009] Preferably, the adjustment unit includes a limiting block that is slidably disposed inside the sample frame, and the side wall of the limiting block is connected to a sliding frame.

[0010] Preferably, the sliding frame has a sliding groove inside, the inner wall of the sliding groove is connected to a first magnetic block, a second magnetic block is slidably disposed inside the sliding groove, the side wall of the second magnetic block is connected to a locking pin, and the sample frame has a locking hole inside.

[0011] Preferably, the sample frame and the sliding frame are made of aluminum alloy. The sample frame is connected by bolts and hinges. With the aluminum alloy material, damage to the sample frame and the sliding frame can be reduced. The detachable hinges and sample frame make the frame easier to carry.

[0012] Preferably, the second magnetic block and the first magnetic block are magnetically repulsive, and the outer wall of the locking pin is slidably disposed inside the groove. Under the restriction of magnetic repulsion, the locking pin, which is not squeezed, can be reset and pushed.

[0013] Preferably, the outer wall of the locking pin engages with the inside of the locking hole, and the locking pins are equidistantly distributed inside the sliding frame. Under the restriction of the locking pins and the locking hole, the adjusted sliding frame can be restricted inside the sample frame.

[0014] Preferably, the positioning unit includes a locking pin, and an anti-dislodgement pin is fixedly installed on the outer wall of the locking pin.

[0015] Preferably, the anti-detachment nails are inclined and equidistantly distributed on the outer wall of the clamp. With the anti-detachment nails assisting in the restraint of the clamp, the clamp is stably embedded in the soil, avoiding displacement of the sliding frame and sample box during use, which would affect the data accuracy.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This portable quadrat frame for desert plant surveys comprises an adjustment unit. During desert plant surveys, the assembled quadrat frame is used to sample grassland areas. The collected plant data are then statistically analyzed. For adaptive sampling, pressing the locking pin causes the second magnetic block to slide into the groove. At this point, the locking pin is no longer engaged with the locking hole inside the quadrat frame. Sliding the sliding frame within the quadrat frame adjusts its length, allowing for adaptive adjustment of the selected area size as needed. Once adjustment is complete... Align the locking pin with the locking hole. Under the magnetic repulsion of the first and second magnetic blocks, push the locking pin to engage with the locking hole, thus confining the adjusted sliding frame inside the sample box. This structure can adaptively adjust the sample box and sliding frame area according to the sample size. After data acquisition is completed, remove the bolts connecting the hinge and the sample box, and then retract the sliding frame into the sample box to make the equipment easier to carry. Since the sample box and sliding frame are made of aluminum alloy, damage during use is reduced, thus extending their service life.

[0018] 2. This portable quadrat frame for desert plant surveys consists of a positioning unit. When surveying desert plants, the hinges are bolted to the quadrat frame. The length of the sliding frame and the quadrat frame is then adjusted as needed. After the extraction dimensions are adjusted, the clips fixed at the bottom of the sliding frame and the quadrat frame are pressed towards the grassland, causing the clips to drive the anti-detachment nails into the soil. Because the anti-detachment nails are inverted, they prevent the clips from slipping out of the soil. Attached Figure Description

[0026] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0027] Example 1

[0028] Reference Figure 1 and Figure 2 This is the first embodiment of the present utility model. This embodiment provides a portable sample frame for desert plant survey, including a hinge 1 and a sample frame 2 on the outer wall of the hinge 1.

[0029] Adjustment unit 3 is placed inside the sample frame 2 and extends to the outside of the sample frame 2. Adjustment unit 3 includes a sliding frame 32, a first magnetic block 34, a second magnetic block 35 and a locking pin 36, which are used to position and limit the adjusted sliding frame 32 by the locking pin 36 under the restriction of magnetic repulsion.

[0030] Positioning unit 4 is placed at the bottom of quadrat frame 2 and is used to position quadrat frame 2 and sliding frame 32 on the grass.

[0031] During use, the quadrature frame 2 and the adjustment unit 3 can be adjusted flexibly and adaptably under the constraints of hinge 1, quadrature frame 2 and adjustment unit 3. Under the constraints of positioning unit 4, the quadrature frame 2 and adjustment unit 3 can be stably placed on the grass to prevent displacement during use, which would affect the accuracy of sample data.

[0032] Example 2

[0033] Reference Figure 3 and Figure 4 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment is further optimized based on the above embodiment, as follows:

[0034] The adjustment unit 3 includes a limiting block 31 that is slidably disposed inside the sample frame 2. A sliding frame 32 is connected to the side wall of the limiting block 31. A sliding groove 33 is provided inside the sliding frame 32. A first magnetic block 34 is connected to the inner wall of the sliding groove 33. A second magnetic block 35 is slidably disposed inside the sliding groove 33. A locking pin 36 is connected to the side wall of the second magnetic block 35. A locking hole 37 is provided inside the sample frame 2.

[0035] The sample frame 2 and the sliding frame 32 are made of aluminum alloy. The sample frame 2 is connected to the hinge 1 by bolts. The aluminum alloy material reduces the risk of damage to the sample frame 2 and the sliding frame 32. The detachable hinge 1 and sample frame 2 make the frame easier to carry.

[0036] The second magnetic block 35 and the first magnetic block 34 are magnetically repulsive. The outer wall of the locking pin 36 is slidably disposed inside the sliding groove 33. Under the restriction of magnetic repulsion, the locking pin 36, which is not squeezed, can be reset and pushed.

[0037] The outer wall of the locking pin 36 engages with the inside of the locking hole 37. The locking pins 36 are equidistantly distributed inside the sliding frame 32. Under the restriction of the locking pins 36 and the locking hole 37, the adjusted sliding frame 32 can be restricted inside the sample frame 2.

[0038] When using this system, during desert vegetation surveys, it is necessary to sample grassland using the combined quadrat frame 2, and then statistically analyze the plant data collected in quadrat frame 2. For adaptive sampling, press the locking pin 36, which causes the second magnetic block 35 to slide into the slide groove 33. At this point, the locking pin 36 is no longer engaged with the locking hole 37 inside the quadrat frame 2. Sliding the slide frame 32 within the quadrat frame 2 allows adjustment of the length of the quadrat frame 2 and the slide frame 32, enabling adaptive adjustment of the selected area size according to requirements. After adjustment, align the locking pin 36 with the locking hole 37, and then... Under the magnetic repulsion constraint of the magnetic block 34 and the second magnetic block 35, the locking pin 36 is pushed, which makes the locking pin 36 engage with the locking hole 37, thus restricting the adjusted sliding frame 32 inside the sample box 2. This structure can adaptively adjust the area of ​​the sample box 2 and the sliding frame 32 according to the size of the sample. After the data acquisition is completed, the bolt connecting the hinge 1 and the sample box 2 is removed, and the sliding frame 32 is then shrunk into the sample box 2, making the equipment easier to carry. Since the sample box 2 and the sliding frame 32 are made of aluminum alloy, damage during use is reduced, thus extending their service life.

[0039] Example 3

[0040] Reference Figure 5 and Figure 6 This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment is further optimized based on the above embodiments, as detailed below:

[0041] The positioning unit 4 includes a clip 41, and an anti-detachment clip 42 is fixedly installed on the outer wall of the clip 41.

[0042] Among them, the anti-detachment nail 42 is set at an angle and is equidistantly distributed on the outer wall of the clamp 41. With the anti-detachment nail 42 assisting in restricting the clamp 41, the clamp 41 is stably embedded in the soil, avoiding displacement of the sliding frame 32 and the sample box 2 during use, thus affecting the data accuracy.

[0043] When using it, when surveying desert plants, the hinge 1 and the sample frame 2 are installed with bolts. Then, the length of the sliding frame 32 and the sample frame 2 is adjusted according to the needs. After the extraction size is adjusted, the clips 41 fixed at the bottom of the sliding frame 32 and the sample frame 2 are pressed towards the grassland, so that the clips 41 drive the anti-detachment nails 42 to embed into the soil. Since the anti-detachment nails 42 are inverted, the clips 41 can be prevented from sliding out of the soil under their restriction.

[0044] The above are merely illustrative embodiments of this utility model and are not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model. Furthermore, it should be noted that the components of this utility model are not limited to the overall application described above. Each technical feature described in the specification can be used individually or in combination as needed. Therefore, this utility model naturally covers other combinations and specific applications related to the points of this utility model.
