Description

Technical Field

[0001] The utility model relates to the technical field of vegetation observation and collection, in particular to a quadrat device with a folding function. Background Technique

[0002] The quadrat method investigation is an important way to obtain data in vegetation investigation and ecosystem research, revealing key contents such as the species composition, distribution pattern, structure and function of the vegetation in the research area. Data is collected with quadrats of different sizes as the investigation units in different regions. Usually, the vegetation quadrat for herb investigation is 1 m×1m. The vegetation quadrat is used to define the sampling area. When sampling, the quadrat is placed on the ground or above the vegetation, and plant community information such as the plant species, abundance, height, and coverage within the quadrat frame is recorded or collected. The vegetation quadrat sampling device can help researchers quickly and accurately obtain vegetation data, which is used to obtain basic data for research in vegetation ecology, botany, geography, etc.

[0003] Existing vegetation quadrats are either made on-site using three strands of nylon rope and nails, or are quadrat frames of a fixed size. For the on-site made vegetation quadrat, four nails are used to locate an area, and then a rope is wound around the four nails to form a square, and vegetation investigation is carried out within this square area. The quadrat frame of a fixed size is a square frame composed of four PVC pipes and elbows connected end to end. Both of these two types of vegetation quadrats have the problem of inconvenient use. Among them, although the on-site made nylon rope quadrat frame is convenient to carry and does not occupy space, the made square is not standard, the side length is unstable, nails are likely to fall off during field operations, and the nylon rope is prone to knotting, which is time-consuming and laborious. The fixed-size quadrat frame occupies a large amount of space when not disassembled, and elbows are likely to fall off during field operations when disassembled, making it inconvenient to carry. Therefore, it is necessary to design a quadrat device to solve the problem of inconvenient use of existing vegetation quadrats. Content of the Utility Model

Detailed Embodiments

[0032] In order to make the objectives, technical solutions and advantages of this application clearer and more understandable, the following describes and explains this application in combination with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not used to limit this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments provided in this application without creative efforts belong to the scope of protection of this application.

[0033] As Figures 1-7 shown, a quadrat device with a folding function has an inner side length of 1 m, and the area of the opened quadrat is 1 m 2， It includes a first quadrat rod 1, a second quadrat rod 2, a third quadrat rod 3, and a fourth quadrat rod 4 that are connected end to end. The rear end of the first quadrat rod 1 is hinged to the front end of the second quadrat rod 2, the rear end of the second quadrat rod 2 is hinged to the front end of the third quadrat rod 3, the rear end of the third quadrat rod 3 is hinged to the front end of the fourth quadrat rod 4, and there is no direct connection between the rear end of the fourth quadrat rod 4 and the front end of the first quadrat rod 1, and a first support rod 51 is needed for fixation.

[0034] As Figures 1-2 shown, the first quadrat rod 1 includes a first front rod perforation 11, a first rear rod perforation 12, a first sector baffle 13, a support rod storage cavity 62, and a storage cavity 6.

[0035] As Figures 3-4 shown, the second quadrat rod 2 includes a second front rod perforation 21, a second rear rod perforation 22, a second sector baffle 23, and a storage cavity 6.

[0036] As Figures 5-6 shown, the third quadrat rod 3 includes a third front rod perforation 31, a third rear rod perforation 32, a third sector baffle 33, a first rod section 34, a second rod section 35, an insertion rod 36, a slot 37, and a storage cavity 6.

[0037] As Figure 7 shown, the fourth quadrat rod 4 includes a fourth front rod perforation 41, a fourth rear rod perforation 42, and a storage cavity 6.

[0038] Adjacent quadrat rods are connected by support rods. Therefore, there are 4 support rods in total, and the number of support rod storage cavities 62 is four, and each support rod occupies one support rod storage cavity 62.

[0039] The length of the support rod is 20 cm, and the support rod can be inserted into the soil to support the quadrat device at a height of 10 cm above the ground.

[0040] The length of each quadrat rod is 1 m, and the thickness is 1.5 - 2 cm.

[0041] The arrangement of the first quadrat rod 1, the second quadrat rod 2, the third quadrat rod 3 and the fourth quadrat rod 4 in the height direction is ascending or descending in sequence, so that the first quadrat rod 1, the second quadrat rod 2, the third quadrat rod 3 and the fourth quadrat rod 4 can be stacked on top of each other in sequence. In this embodiment, the first quadrat rod 1, the second quadrat rod 2, the third quadrat rod 3 and the fourth quadrat rod 4 are stacked from bottom to top. Since the height of the fourth quadrat rod 4 is about 4 cm higher than that of the first quadrat rod 1, it is not easy to connect the two. Therefore, the third quadrat rod 3 is changed into two sections, and the first rod section 34 and the second rod section 35 can rotate relative to each other, so that the fourth quadrat rod 4 can rotate following the second rod section 35, and the rear end of the fourth quadrat rod 4 is aligned with the front end of the first quadrat rod 1, which is convenient for connection.

Then, the second quadrat rod 2, the third quadrat rod 3 and the fourth quadrat rod 4 all rotate clockwise. Then, the second quadrat rod 2 is limited by the first sector baffle 13, as shown in Figure 9 shown. The third quadrat rod 3 is limited by the second sector baffle 23, as shown in Figure 10 shown. Rotate the second rod section 35 of the third quadrat rod 3 so that the lower surface of the rear end of the fourth quadrat rod 4 is at the same height as the upper surface of the front end of the first quadrat rod 1. Continue to rotate the fourth quadrat rod 4 clockwise to reach the state shown in Figure 11 shown. Then, insert the first support rod 51, the second support rod 52, the third support rod 53 and the fourth support rod 54 into the corresponding through holes respectively, and insert each support rod into the soil at the predetermined position. The user records and collects the ground vegetation surrounded by the quadrat device, and the collected vegetation is put into the storage cavity 6. After the collection is completed, pull out the first support rod 51, the second support rod 52, the third support rod 53 and the fourth support rod 54 from the soil, and then put these support rods back into the support rod storage cavity. Each quadrat rod rotates counterclockwise and returns to the state shown in Figure 8 shown, completing one preparation of the quadrat collection.

[0043] The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited to the above embodiments. All technical solutions within the idea of the utility model belong to the protection scope of the utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the utility model, several improvements and refinements should be regarded as within the protection scope of the utility model.
