Abstract
Description
Technical Field
[0001] The utility model belongs to the field of field experimental systems, in particular to a rainfall reduction experimental device used in alpine peatlands. Background Art
[0002] Droughts are becoming more frequent in the context of global climate change, making research on the response and adaptability of peatland ecosystems to drought a crucial topic. However, field experiments are often affected by uncontrollable factors such as the environment and natural rainfall, making it difficult to accurately simulate drought conditions, especially in the harsh natural environment of the Qinghai-Tibet Plateau.
[0003] However, even when studying alpine peatland ecosystems, it is necessary to minimize interference with the natural state of the ecosystem while meeting experimental or observational needs, such as reducing the impact of experimental equipment on environmental factors such as light, temperature, humidity, air circulation, and the impact on the ecosystem's biological communities and their dynamics. Utility Model Content
[0004] In order to solve the above technical problems, the utility model discloses a rain reduction experimental device for alpine peatlands, which can well realize simulated rain reduction, accurately obtain experimental structure, and avoid interference with the natural state of the ecosystem.
[0005] The specific technical solutions of the utility model are as follows:
[0006] A rainfall reduction experimental device for alpine peatland, comprising:
[0007] A rain interception component, which is used to divert rainwater to the outside of the sample plot;
[0008] a support assembly for supporting the rain interception assembly above the ground in an alpine peatland; and
[0009] A water cut-off assembly includes a waterproof component that is enclosed outside the support assembly and extends below the ground of the alpine peatland.
[0010] The rain interception component can realize rainwater diversion, effectively guiding rainwater to flow to the designated area along the diversion direction, and preventing excess rainwater from dripping directly into the experimental area and reducing the accuracy of the experiment; the water cut-off component can realize a water flow blocking zone to prevent water infiltration, thereby preventing factors outside the experimental area from affecting the experimental treatment; in addition, the rain reduction experimental device can well maintain the light, temperature, humidity, air circulation, etc. of the experimental area, and will not affect the ecosystem biological community and its dynamics, and is suitable for field control experiments.
[0011] Preferably, the rain interception assembly comprises a plurality of rain interception members arranged in pairs and spaced side by side, and any pair of rain interception members has extended and intersecting apex angles, and the apex angles are arranged away from the ground of the alpine peatland.
[0012] This structure can effectively divert rainwater through its own gravity and inertia when falling, without the need to design rainwater driving components. Moreover, when any pair of rain intercepting pieces form a triangular structure, the structure is stable and has stronger wind resistance than arched awnings.
[0013] Preferably, in any pair of rain intercepting members, the length of one rain intercepting member is greater than the length of the other rain intercepting member to prevent rainwater from leaking from the top of the supporting assembly.
[0014] This structure can enable the end of one rain interception piece in any pair of rain interception pieces to extend above the other rain interception piece, thereby avoiding installation interference. In addition, when rain comes, it can prevent the formation of a gap between the two rain interception pieces, which would cause rainwater beyond the preset data to fall into the experimental area.
[0015] Preferably, the rain intercepting member has a guide groove with a converged structure.
[0016] The structure is simple and can well realize diversion, so that the diversion avoids the intersection of the diversion paths, and at the same time well realizes the simulation of rain reduction.
[0017] Preferably, the vertex angle is 120°.
[0018] When the top angle is 120°, the rain interception process can be smooth and the rainwater can fall well to the designated area.
[0019] Preferably, the rain intercepting member is made of organic glass.
[0020] When the rain intercepting piece is made of organic glass, it can effectively transmit nearly 100% of solar radiation, thereby achieving the effect of shielding from rain without affecting the lighting conditions of the experimental area and facilitating drainage.
[0021] Preferably, the waterproof member is configured as an iron barrier.
[0022] When the waterproof part is configured as an iron barrier, it can effectively prevent soil moisture from seeping.
[0023] Preferably, a thick plastic film is attached to the outer side of the waterproof component.
[0024] The thick plastic film can further prevent soil moisture from seeping.
[0025] Preferably, the end of the above-ground part of the waterproof component is not less than 30 cm from the ground; the end of the underground part of the waterproof component is not less than 80 cm from the ground; and the distance between the waterproof component and the supporting assembly is not less than 45 cm.
[0026] Such a setting can further prevent soil moisture leakage and avoid affecting the ecosystem biological community and its dynamics.
[0027] Preferably, the support assembly includes: a frame consisting of a plurality of columns; a triangular member, which is arranged above the frame and is used to connect the rain interception assembly; and a pipe fitting that connects each column in sequence from head to tail.
[0028] The structure is stable, easy to install, and facilitates quick assembly and disassembly, reducing transportation and installation costs. In addition, the structure leaves the experimental device unenclosed on all sides, ensuring normal air circulation to minimize the greenhouse effect caused by the enclosed experimental device.
[0029] In order to study scientific issues such as the growth characteristics of alpine peatland plants, soil physical and chemical properties, and changes in microbial community structure under simulated rainfall reduction conditions, the utility model provides an experimental device with high structural strength, high precision and good effect in simulating rainfall reduction conditions, which can avoid the impact on environmental factors and avoid affecting the ecosystem biological community and its dynamics.

[0035] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with specific implementation methods.
[0036] like Figures 1 to 4As shown, a rain reduction experimental device for alpine peatland includes a rain interception component, a support component and a water cut-off component; the rain interception component is used to divert rainwater to the outside of the sample site; the support component is used to support the rain interception component above the ground 1 of the alpine peatland; the water cut-off component includes a waterproof part 2 for enclosing the outside of the support component and extending under the ground 1 of the alpine peatland.
[0037] The rain interception component can achieve rain reduction, so that only part of the rainwater falls into the experimental area, and the other part falls to the designated position along the guiding direction of the rain interception component, avoiding affecting the experimental results. The waterproof part 2 encloses the experimental area to form a water flow blocking zone, thereby avoiding water leakage and affecting the experimental results. Usually, for some rain reduction experimental devices, the cross-section of the rain interception component is an arched structure. The arched structure itself has a certain bearing capacity, but under extreme weather conditions, such as strong winds, heavy rain or heavy snow, its stability may be challenged. This structure may be more susceptible to wind force, resulting in deformation or damage, thereby affecting its rainproof effect and service life. In addition, when the cross-section of the rain interception component is an arched structure, its design and installation may require more time and cost expenditures, and maintenance also requires a higher level of technology. For example, once problems such as leakage, rust and breakage occur, it is more difficult to repair and requires professional technicians to carry out maintenance. Therefore, if Figure 3 As shown, in this embodiment, the cross-section of the rain interception component is set to a triangular structure, which can improve the required effects of cooling, ventilation, etc. while avoiding the above-mentioned defects. Specifically, the rain interception component includes a number of rain interception pieces 3 arranged in pairs and spaced side by side, and any pair of rain interception pieces 3 has an extended intersecting apex angle, and the apex angle is set away from the ground 1 of the alpine peatland. Furthermore, the angle of the apex angle is 120°. Any pair of rain interception pieces 3 is configured as a triangular structure, and its structural stability can enhance the wind resistance. Further, the rain interception piece 3 has a guide groove in a gathering structure. As a result, the rain interception piece 3 is conducive to the rapid sliding of rainwater, reduces water accumulation, and effectively guides rainwater to flow to the designated area along the diversion direction, avoiding rainwater from dripping directly into the experimental area. It can be seen that the above-mentioned sample plot refers to the experimental area.
[0038] In this embodiment, the guide groove is a V-shaped structure, but it can also be an arc structure. Furthermore, in this embodiment, the guide groove forms a continuous V-shaped structure. Specifically, the guide groove is configured with a V-shaped organic glass material to ensure complete light transmission, long-term use without rust, and water leakage.
[0039] In this embodiment, in any pair of rain intercepting members 3, the length of one rain intercepting member 3 is greater than the length of the other rain intercepting member 3 to prevent rainwater from leaking from the top of the supporting assembly. Figure 3As shown, the length of the rain intercepting piece 3 on the left is greater than that of the rain intercepting piece 3 on the right. Therefore, the end of the rain intercepting piece 3 on the left is located above the rain intercepting piece 3 on the right, so that interference can be avoided during the installation process and it also has a better aesthetics. In addition, it can also avoid the formation of gaps between the rain intercepting pieces 3 on the left and right sides, which may cause rainwater to leak from there.
[0040] like Figures 1 to 4 As shown, in this embodiment, the waterproof component 2 is configured as an iron barrier. The end of the above-ground part of the waterproof component 2 is not less than 30 cm from the ground 1; the end of the underground part of the waterproof component 2 is not less than 80 cm from the ground 1; the distance between the waterproof component 2 and the supporting assembly is not less than 45 cm. When the waterproof component 2 forms a closed water flow blocking zone, the bottom of the iron barrier is embedded in the soil to a certain depth to ensure that groundwater does not penetrate into the experimental area from the side. Furthermore, a thick plastic film is attached to the outside of the waterproof component 2 to prevent moisture penetration. In this embodiment, soil sealing treatment is also performed on the contact part between the waterproof component 2 and the ground 1 to further prevent moisture penetration.
[0041] Therefore, in this embodiment, the triangular structure of the rain interception component can effectively block rainwater, combined with the V-shaped guide groove to achieve rapid drainage, and the iron barrier around the ground 1 is used to block the water system to achieve simulated rain reduction conditions in the experimental area with high precision and good effect.
[0042] In this embodiment, if Figures 1 to 4 As shown, the support assembly includes a frame 4 composed of multiple columns and a triangular member; the triangular member is arranged above the frame 4 and is used to connect the rain interception assembly; it also includes a pipe 1 5 that connects each column in sequence from end to end. The pipe 1 5 is configured as a stainless steel pipe, which has the characteristics of light weight and high strength, can enhance the stability of the overall structure, and is conducive to use in harsh experimental environments. Therefore, the columns can also be made of stainless steel. Based on this, there are gaps between the multiple columns, and there are gaps between any pair of rain interception members 3, so that the overall structure is an unenclosed structure, which is conducive to ensuring normal air circulation in the experimental area and minimizing the greenhouse effect caused by the closed overall structure. Therefore, through this embodiment, natural precipitation changes can be controlled while minimizing interference with environmental factors such as natural light and ventilation in the experimental area, thereby better realizing the study of alpine peatland ecosystems. The triangular member includes a base member 7 made of pipe 2 6 and a connector 8 for connecting the base member 7. Among them, on the basis of the cubic structure of the frame 4 of this embodiment, multiple base members 7 are set along the length direction of the frame 4. It can be seen that the connecting member 8 extends along the length direction of the frame 4. Therefore, the connecting member 8 can be well bound to the rain interception member 3 through the wire, thereby realizing the installation of the rain interception assembly. Figure 3As shown, at least two rain interception members 3 should be provided on each of the left and right sides of the frame 4 to ensure stable installation. In this embodiment, to facilitate installation, the rain interception members 3 are positioned below the connector 8. Furthermore, a reinforcement member, configured as a pipe member 9, may be provided extending along the arrangement direction of the rain interception members 3 to enhance connection stability. Multiple reinforcement members may also be provided along the length of the rain interception members 3. In practice, the base member 7 may also be provided with multiple support members 10 to further stabilize the triangular structure, thereby ensuring stable assembly during welding.
[0043] The above are merely preferred embodiments of the present invention. It should be noted that the above preferred embodiments should not be construed as limiting the present invention. The scope of protection of the present invention shall be determined by the scope defined in the claims. Persons skilled in the art will appreciate that improvements and modifications may be made without departing from the spirit and scope of the present invention, and such improvements and modifications shall also be considered within the scope of protection of the present invention.
