[0024] Please refer to Figure 1 The present embodiment provides a precipitation control device 100, comprising: A plurality of test plots 110 are arranged at intervals on the ground surface, and a soil monitoring unit for monitoring the soil state is arranged in each test plot 110; A rain shielding mechanism 120, the rain shielding mechanism 120 comprises a movable frame 121 and a movable rain shielding plate 122, the movable rain shielding plate 122 is movably connected with the movable frame 121; the movable rain shielding plate 122 is used to move to the area above all the test plots 110, or to move to the area above one of the test plots 110 to intercept the precipitation; The water collecting assembly 130 includes a water collecting pipe 131 and a water collecting tank 132. One end of the water collecting pipe 131 is in communication with the movable rain shield 122, and the other end of the water collecting pipe 131 is in communication with the water collecting tank 132, so as to converge the rainwater collected by the movable rain shield 122 to the water collecting tank 132. The water supplement assembly 140 includes a water pump 141 and at least one water guide pipe 142. The water pump 141 is arranged in the water collecting tank 132, and the water guide pipe 142 is connected with the water pump 141. The water pump 141 is used for supplementing water in the water collecting tank 132 to one of the test plots 110 through the water guide pipe 142. The rain gauge 150 is used for measuring the natural precipitation.
[0025] Please refer to Figure 1 The working principle of the precipitation control device 100 is as follows: Firstly, the precipitation control device 100 is used for field in-situ test in this embodiment, and in other embodiments of the present application, it can be applied to precipitation control related experiments in other scenes.
[0026] The rain gauge 150 is used for measuring the natural precipitation, that is, through the rain gauge 150, the precipitation intensity and total amount in the natural precipitation process can be monitored in real time, and the water supplement assembly 140 is linked to complete the water supplement amount calibration; Secondly, the precipitation control device 100 includes a plurality of test plots 110, and the plurality of test plots 110 are arranged at intervals on the ground. Each test plot 110 is provided with a soil monitoring unit for monitoring the soil state. Thus, through such a setting mode, quantitative precipitation intervention on different test plots 110 can be realized by reducing or compensating precipitation, and then a plurality of test plots 110 can be provided for comparison, so as to have the ability to verify the comparison while reducing or compensating the precipitation, and then the flexibility and repeatability of the experimental design can be improved; The rain shielding mechanism 120 is used for reducing the precipitation of the test plot 110, and the movable frame 121 and the movable rain shield 122 are arranged. The movable rain shield 122 is movably connected with the movable frame 121. The movable rain shield 122 is used for moving to the area above all the test plots 110 or moving to the area above one of the test plots 110 to intercept the precipitation, that is, the movable rain shield 122 is away from the upper area of the test plot 110 in the standby state, and after receiving the operation signal, it is moved to the upper area of the target plot to complete the rain shielding operation. Therefore, when it moves to the area directly above all the test plots 110, the disturbance to the in-situ ecosystem can be reduced, and the formation of a shelter or canopy effect can be avoided. When it is necessary to intercept precipitation in one of the test plots 110, the movable rain shield 122 can be moved to the area directly above the test plot 110 by adjusting the movable frame 121, so that the precipitation can be intercepted. In addition, when the movable rain shield 122 is configured, the amount of precipitation intercepted can be adjusted by replacing the movable rain shield 122 or adjusting the structure of the movable rain shield 122, so that the precipitation can be precisely controlled in a diversified manner. The water collection assembly 130 is used to collect the precipitation intercepted by the movable rain shield 122, and the collected water is converged to the water collection tank 132. The water supplement assembly 140 can supplement the water in the water collection tank 132 to one of the test plots 110 through the water pump 141 and the water guide pipe 142, so that the precipitation in the test plot 110 can be compensated. Therefore, the rain shielding mechanism 120 can be used in cooperation with the above-mentioned rain shielding mechanism 120, so that the amount of precipitation can be reduced or compensated, the flexibility and repeatability of the experimental design can be improved, and the precipitation can be precisely controlled in a diversified manner. In summary, the precipitation control device 100 can be used for in-situ experiments in the field. The device can quantitatively intervene in the precipitation of different test plots 110 by reducing or compensating the precipitation. The device can adapt to the multi-climate environment in the field, can observe the response of the soil environment under the influence of precipitation in-situ, and can be automated, low-disturbance, and controllable.
[0027] It should be noted that the water pump 141 is a quantitative flow pump with an accuracy of better than ± 3%, and is connected with the rain gauge 150 to dynamically adjust the water supplement amount and simulate the enhanced precipitation treatment scenario.
[0028] On the basis of the above structure, an isolation plate is provided between each test plot 110 to prevent surface runoff from crossing. Therefore, on the basis of the above-mentioned arrangement of the test plots 110 on the natural surface of the sample plot, the test plots 110 can be used for in-situ rain control experiments. Such a structure does not require shading, wind shielding, and dustproof structures, and can maintain natural ventilation and illumination, thereby reducing habitat disturbance, and the physical isolation plate between each test plot 110 can prevent surface runoff from crossing. In addition, when the test plots 110 are configured, the diameter of the test plots 110 is not less than 60 cm, and the isolation plate is made of impermeable material to enhance the independence and data comparability between the test plots 110.
[0029] Further, please refer to Figure 1In the configuration of the movable rain shield 122, it plays a role in intercepting precipitation, and in the process of interception, the amount of intercepted rainfall can be adjusted by replacing or adjusting the structure of the movable rain shield 122, thereby achieving diversified and precise regulation of precipitation. In this embodiment, the movable rain shield 122 includes a main body 123 and a plurality of flow guide grooves 124. The main body 123 is provided with a rain guide opening 125, and the plurality of flow guide grooves 124 are detachably arranged in the opening area of the rain guide opening 125 in a predetermined manner to shield at least part of the rain guide opening 125 and intercept precipitation. The water collecting pipe 131 is in communication with all the flow guide grooves 124.
[0030] Thus, by adjusting the number and arrangement of the flow guide grooves 124 arranged at the rain guide opening 125, the installation number of the flow guide grooves 124 can be used to adjust the precipitation reduction ratio, thereby achieving precise adjustment of the amount of intercepted rainfall. Moreover, the flow guide grooves 124 on the rain shielding mechanism 120 can be modularly installed through plug-in structure, supporting rapid replacement of different reduction ratio modules based on experimental design, and the reduction rate can be accurately adjusted to 0%, 25%, 50%, 75% or 100%, or other customized ratios. Moreover, to improve the interception efficiency when intercepting precipitation, the flow guide grooves 124 can be designed as V-shaped to improve their water collecting capacity. In addition, in the case of low temperature frost and snow in low temperature environment, the solid precipitation is heated and melted to improve its fluidity, so that it can quickly flow into the water collecting tank 132. Therefore, each flow guide groove 124 is provided with a heating resistance wire 127. It should be noted that the flow guide groove 124 is designed as a heat preservation structure to prevent freezing in cold environment.
[0031] In addition, the main body 123 is connected with a raindrop sensor 126, which is used to sense rainfall, thereby being able to monitor the precipitation process and being able to be linked with the above-mentioned rain shielding mechanism 120 to start the rain shielding mechanism 120 in time under the condition of rainfall.
[0032] Based on this, in order to improve the uniformity of water supplementing into the test plot 110, please refer to Figure 1 The water supplementing assembly 140 further includes a microporous water permeation pipe 143, which is arranged at the top end of one of the test plots 110 and connected with the drainage end of the water guide pipe 142. Moreover, in this embodiment, since the test plot 110 is arranged in a ring shape, the microporous water permeation pipe 143 is designed in a similar ring shape as the test plot 110, and a plurality of drainage holes are formed on the ring pipe body to improve the uniformity of water supplementing. Therefore, by setting up the water replenishment component 140, water can be replenished into the test sample 110 in a quantitative manner according to the test plan. That is, when the water replenishment operation is triggered, the water pump 141 can extract the stored water in the water collection tank 132 according to the set flow rate and replenish water to the designated test sample 110 through the microporous seepage pipe 143 to increase the precipitation.
[0033] From the above, please refer to Figure 1 In this embodiment, a movable rain shield 122 is movably connected to a movable frame 121, so that it can move relative to each test sample 110. On this basis, in order to improve the degree of automation of the device, as well as the accuracy and controllability of operation, the movable frame 121 includes a lifting column 128 and a mounting frame 129. The mounting frame 129 is connected to the lifting column 128, and the movable rain shield 122 is movably connected to the mounting frame 129; and multiple test samples 110 are arranged in sequence along a preset direction. The rain shield mechanism 120 also includes a driving mechanism, which is transmission-connected to the movable rain shield 122, and the driving mechanism is used to drive the movable rain shield 122 to move relative to the mounting frame 129 along the preset direction.
[0034] Therefore, taking the configuration of three test plots 110 as an example, the three test plots 110 are arranged in sequence, and the three test plots 110 are respectively precipitation control plots (such as Figure 1 As shown by the mark A in the middle), precipitation supplement quadrat (such as Figure 1 B in the middle) and the blank control sample (as shown in Figure 1 At this time, the driving mechanism is used to drive the movable rain shield 122 to move along the arrangement direction of the three test samples, that is, to move relative to the mounting frame 129 along the preset direction, so that it can be moved to the area directly above all the test samples 110, or to be moved directly above one of the test samples 110 to intercept precipitation; at the same time, its height relative to the ground can also be adjusted by the lifting column 128, and the lifting range can be set to 0-100 cm.
[0035] It should be noted that the rain shielding mechanism 120 is driven by the lifting column 128 and the driving mechanism. Both the lifting column 128 and the driving mechanism can adopt the existing linear drive module, so they are not described here. In the standby state, it is located outside all the test samples 110. During operation, it can be moved to the top of the target test sample 110 to perform rain control operations. The operation start signal of the rain shielding mechanism 120 is provided by the raindrop sensor 126 installed thereon.
[0036] When the number of test quadrat 110 increases and is arranged in arrays in multiple directions, the driving mechanism can be used to drive the movable rain shield 122 to move in multiple directions, and the movement directions can be in the same horizontal plane.
[0037] Further, in order to comprehensively detect the soil in each test plot 110, when the soil monitoring unit is configured, each soil monitoring unit includes a plurality of soil temperature, humidity and salt sensors, which are buried at different depths of the test plot 110 for in-situ observation of the soil response process after the intervention of precipitation. In this embodiment, the plurality of soil temperature, humidity and salt sensors are buried at 5 cm, 10 cm, 20 cm, 30 cm and 50 cm below the ground surface of the test plot 110, respectively, for real-time feedback of the soil state change under the control of rain treatment.
[0038] In addition to the above structure, please refer to Figure 1 The device further includes a power supply and control system 170, wherein the power supply system 160 includes a photovoltaic power supply unit, a main control circuit module and a communication module, so as to supply power through photovoltaic power generation by the photovoltaic power supply unit, and through the electrical connection of the main control circuit module and the communication module with the control system 170, the data reception, transmission and processing of each sensor in the device, as well as the triggering, execution and remote data communication function of the operation logic of the rain blocking mechanism 120 and the water supplement assembly 140 can be realized. Moreover, the control system 170 supports program setting and remote operation, and can set the working time window, target reduction ratio and automatic calibration logic, and has the ability to automatically recover after power failure. It should be noted that the power supply and control system 170 can adopt existing technology, which will not be described here.
[0039] In summary, please refer to Figure 1 The working principle of the precipitation control device 100 is as follows: Through the servo system and the PID algorithm, the sensing calculation of the raindrop sensor 126 needs to be accurately responded, so as to avoid errors caused by slow response, and avoid invalid operation caused by false response, which disturbs the sample plot habitat; The rain blocking mechanism 120 after response also dynamically monitors the operation time, but resets at the first time after the precipitation stops; The operation logic supports remote control, and under the assistance of remote monitoring, manual start or stop operation can be realized, and according to the demand, start or pause start can be realized at different times; The rain blocking mechanism 120 can start the operation mode at dawn and dusk according to the program setting, so as to realize the interception operation of abnormal precipitation, such as blocking dew or frost precipitation at a specified position above the test plot 110, so as to reduce the test error; The water collection assembly 130 and the water supplement assembly 140 constitute a water collection and supplement operation mechanism, which is equipped with water collection tanks 132 of different sizes and three-way water pipes 142 according to the water supplement operation demand of different precipitation amounts, so as to ensure sufficient water and support the setting of multiple water supplement plots; In the case of carrying out the experiment of increasing precipitation, through the above structural arrangement, the movable rain shield 122 of the rain shield mechanism 120 can be kept outside the target quadrat, and water can be supplemented through the water supplement assembly 140, or the rainwater collected by the movable rain shield 122 can be guided to the target quadrat.
[0040] Please refer to Figure 1 The use steps of the precipitation control device 100 are as follows: The precipitation control device 100 can be used in situ in the field to control natural precipitation in a bidirectional, quantitative and low-disturbance manner to simulate future climate scenarios and monitor soil-vegetation responses. Its work includes “real-time monitoring—intelligent decision-making—mechanical execution—data closed loop”, all links are supported by photovoltaic power supply and remote communication system, without on-site attendance, thereby improving the degree of automation and realizing unmanned; Specifically, when the raindrop spectrum sensor detects precipitation, the signal is immediately transmitted to the control system 170; the rain gauge 150 synchronously records the instantaneous rainfall intensity and the cumulative rainfall, and the control system 170 calculates the target water volume of this rainfall according to the pre-set experimental scheme (such as “reducing 50 %” or “increasing rainfall by 30 %”), and decides whether to start the rain shield mechanism 120 or the water supplement mechanism; When the rainfall needs to be reduced, the servo motor in the driving mechanism drives the movable rain shield 122 to move to the top of the target quadrat, and is lowered to the working height (0-100 cm adjustable) through the lifting column 128, and the height can not be adjusted when it is at the working height; a plurality of detachable V-shaped flow guide grooves 124 intercept natural precipitation with a set projection area; after the raindrops fall into the flow guide groove 124, they flow along the inclined groove bottom to the flow guide port, and then are collected into the bottom water collecting tank 132 through the water collecting pipe 131, so as to accurately reduce the rainfall falling into the soil; under low-temperature conditions such as frost and snow, the heating resistance wire 127 in the flow guide groove 124 can automatically melt the solid precipitation, ensuring continuous flow guide; After the rainfall stops, the data of the rain gauge 150 is used to calculate the water volume that needs to be supplemented. The water pump 141 can quantitatively pump water from the water collecting tank 132 (or external storage water), which is delivered to the micro-porous water permeation pipe 143 laid at the surface layer 2-3 cm of the target quadrat through the water guide pipe 142, and the water is slowly and uniformly infiltrated into the soil, achieving the purpose of increasing rainfall or “returning” the previously intercepted water to the specified test quadrat 110; Soil response monitoring and data return, since the temperature, humidity and salinity sensors are buried at five depths of 5 cm, 10 cm, 20 cm, 30 cm and 50 cm in each quadrat, the changes of soil temperature, moisture content and electrical conductivity after precipitation intervention are recorded in real time; the data can be returned to the control system 170 or the remote server through the wireless communication module at regular intervals, so that researchers can verify the actual effect of the reduction / supplement of water and dynamically adjust the experimental parameters; After a round of rainfall reduction or water replenishment, the rain shielding mechanism 120 is reset and moved out of the space above the test plot 110, returning to the standby area to minimize the interference with the vegetation light, ventilation and microclimate; The entire device can operate continuously unattended in an environment of -20 to +50°C, realizing long-term field comparative tests.
[0041] In summary, the precipitation control device 100 has the following advantages: It provides flexible and adjustable rainfall reduction capability, supports 0-100% precision control, and meets the needs of various experimental designs; Integrated design of flow guiding and water replenishment, which can replenish the reduced rainfall to other plots as needed, supporting simulated rainfall enhancement scenarios; Vertical lifting and position adjustment of the movable rain shield 122 can effectively reduce physical interference with the vegetation, ensuring the integrity of the vegetation structure; All operating processes can be remotely set and automatically executed, significantly reducing manual intervention and operation and maintenance costs; It has good environmental adaptability, supports an operating environment of -20 to +50°C, and is suitable for typical ecological systems such as grasslands, sandy lands, and shrubs.
[0042] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto, and any changes or replacements that can be easily thought of by those skilled in the art within the technical scope disclosed by the present application should be covered within the protection scope of the present application.
