[0047] Reference Figure 1The embodiment of the present invention provides a fully automatic test device for a rain gauge simulating heavy rainfall, comprising a bearing frame 200, a spray plate 700, a first bearing plate 510, a first water storage tank 310, a rain gauge 600 to be connected, and a water pump 400. The bearing frame 200 comprises a first installation layer and a second installation layer, and the first installation layer is located above the second installation layer; the spray plate 700 is movably arranged on the first installation layer of the bearing frame 200; the first bearing plate 510 is arranged on the second installation layer, and the first bearing plate 510 is used to fix the rain gauge 600 to be connected directly below the spray plate 700; the spraying area of ​​the spray plate 700 is equal to or smaller than the water receiving port area of ​​the rain gauge 600 to be connected; the first water storage tank 310 is used to store water; one end of the water pump 400 is connected to the water inlet of the spray plate 700 through the first water pipe 110, and the other end of the water pump 400 is connected to the water outlet of the first water storage tank 310 through the second water pipe 120. The first water tank 310 and the water pump 400 are not subject to the following conditions: Figure 1-3 restrictions.

[0048] In this embodiment, when the fully automatic test device for simulating heavy rainfall is used for operation, the connection of each component is first checked to ensure that the first water pipe 110, the second water pipe 120 and each component are tightly connected. The first water tank 310 can be a water tank with a fixed capacity, and water is added to the first water tank 310 to a fixed capacity position. The water pump 400 is started, and the water in the first water tank 310 is drained to the second water pipe 120 through the operation of the water pump 400; the water pump 400 continues to operate to drain the water in the second water pipe 120 to the first water pipe 110 through the water pump 400, until it is drained into the spray plate 700. The spray plate 700 determines the spray area by setting multiple water outlet positions, so multiple water outlets are set in the spray area. The water drained into the spray plate 700 through the first water tank 310 flows out through the multiple water outlets under the influence of gravity, forming a simulated rainfall effect. It can be understood that because the spraying area of ​​the spray plate 700 is equal to or smaller than the water receiving port area of ​​the rain gauge 600 to be connected, and the rain gauge 600 to be connected is fixed directly below the spray plate 700, the water flowing out through the water outlet of the spray plate 700 can fall completely into the water receiving port of the rain gauge 600 to be connected, thereby preventing the water from flowing out of the water receiving port of the rain gauge 600 to be connected and affecting the data reading of the rain gauge 600 to be connected, thereby providing accurate data values ​​for subsequent testing and calibration of the rain gauge 600 to be connected.

[0049] At the same time, the water of the spray plate 700 flows into the water receiving port of the rain gauge 600 to be connected, and the rain gauge 600 to be connected starts measuring until the spray plate 700 stops simulating rainfall, and the rain gauge 600 to be connected stops measuring. The measuring data of the rain gauge 600 to be connected is compared with the fixed capacity data of the first water storage tank 310. If the data are inconsistent and exceed the allowable error range, the rain gauge 600 to be connected is calibrated. The allowable error range refers to the error data generated by the water sticking or remaining in the water pipe and the spray plate 700 and not falling into the water receiving port of the rain gauge 600 to be connected during the process of water flowing through the water pipe to the spray plate 700 due to the unique viscosity of water or gravity. Exemplarily, taking a tipping bucket rain gauge as the rain gauge 600 to be connected, the tipping bucket rain gauge is fixed directly below the spray plate 700 so that the spraying area of ​​the spray plate 700 is vertically aligned with the water receiving port of the tipping bucket rain gauge; the water in the first water storage tank 310 is drained to the spray plate 700 through the water pump 400, and then the spray plate 700 simulates rainfall and falls into the water receiving port of the tipping bucket rain gauge until the spray plate 700 stops simulating rainfall and the tipping bucket rain gauge stops measuring; the tipping bucket rain gauge measures rainfall based on the flipping of the bucket, specifically, the rainfall is calculated by multiplying the rainfall corresponding to each flip of the bucket and the number of flips of the bucket recorded by the counting device; when the rainfall measured by the tipping bucket rain gauge and the sum of the allowable error range are inconsistent with the fixed capacity of the first water storage tank 310, the tipping bucket rain gauge is capacity calibrated, counting calibrated and accuracy calibrated according to the exceeded error value.

[0050] In some embodiments, Figure 2 As shown, the fully automatic test device for simulating heavy rainfall is also provided with a first intelligent water level sensor 810 in the first water tank 310, and the first water tank 310 is connected to the external water supply end through the third water pipe 130. When the external water supply end supplies water to the first water tank 310, the first intelligent water level sensor 810 is used to provide water supply data of the external water supply end to the first water tank 310; when the external water supply end stops supplying water and the spray plate 700 starts spraying simulated rainfall, the first intelligent water level sensor 810 is used to provide water output data of the first water tank 310. It can be understood that the first water tank 310 of this embodiment does not need to determine the water storage capacity of the first water tank 310 by a fixed capacity, and also saves the need to manually add a fixed volume of water to the first water tank 310, avoiding the uncertainty caused by manual errors. Among them, the external water supply end can be the outlet of the water supply system.

[0051] Specifically, during the water storage process of the first water storage tank 310, the external water supply end is opened to start water supply and flow into the first water storage tank 310 through the third water pipe 130. The first intelligent water level sensor 810 in the first water storage tank 310 determines the amount of water flowing into the first water storage tank 310 according to the difference between the first original water level and the first existing water level. When the first water storage tank 310 supplies water to the spray plate 700, the external water supply end is first shut down and then the water pump 400 is started. The water in the first water storage tank 310 flows into the spray plate 700 through the water pump 400 to start simulating rainfall. The first intelligent water level sensor 810 determines the amount of water flowing out of the first water storage tank 310 according to the difference between the second original water level and the second existing water level. The water amount data flowing out of the first water storage tank 310 is compared with the metering data of the rain gauge 600 to be connected, so as to determine whether the rain gauge 600 to be connected meets the requirements of the regulations. The water level of the first water storage tank 310 is measured by the first intelligent water level sensor 810, which improves the accuracy of the test results.

[0052] In some embodiments, the fully automatic test device for simulating heavy rain also includes a second bearing plate 520 and a second water tank 320; the bearing frame 200 also includes a third installation layer; the third installation layer is located below the second installation layer; the second bearing plate 520 is arranged on the third installation layer; the second water tank 320 is located below the rain gauge 600 to be connected and is arranged on the second bearing plate 520, and the second water tank 320 is connected to the water pump 400 through the fourth water pipe 140. Specifically, in Figure 1-3 In the embodiment, the first water tank 310 and the rain gauge 600 to be connected are both arranged on the first load-bearing plate 510. Under the condition of limited space, the volume of the first water tank 310 is limited. In the specific test and calibration process that requires a large amount of water, it is easy to cause the disadvantage that the water storage in the water tank is insufficient or the test and calibration process needs to be interrupted to wait for the first water tank 310 to store water. In order to avoid such disadvantages, the automatic test device for simulating heavy rain is equipped with a second water tank 320. The second water tank 320 is arranged below the rain gauge 600 to be connected, which saves the space occupied by the test device and prevents the test device from being greatly modified due to the addition of the second water tank 320. The second water tank 320 is connected to the water pump 400 through the fourth water pipe 140. When the second water tank 320 needs to be activated, the original connection port of the second water pipe 120 is disconnected and replaced with the fourth water pipe 140 connected to the water pump 400, so that the water tank replacement of the first water tank 310 and the second water tank 320 can be completed. The second water storage tank 320 may be a water tank with a fixed capacity, and water storage in the second water storage tank 320 is completed by manually supplying water to the fixed capacity.

[0053] In some embodiments, the first water pipe 110, the second water pipe 120, the third water pipe 130 and the fourth water pipe 140 may be hoses and marked with water storage scales for reading the water storage capacity in the corresponding water pipes during testing or calibration, thereby facilitating calculation of the allowable error range.

[0054] In some embodiments, the second water pipe 120 is provided with a first water stop valve 910, the third water pipe 130 is provided with a second water stop valve 920, and the fourth water pipe 140 is provided with a third water stop valve 930. The first water stop valve 910, the second water stop valve 920 and the third water stop valve 930 are respectively arranged near the walls of the first water tank 310 and the second water tank 320, and a three-way water pipe is also provided, which is respectively connected to the water inlet of the water pump 400, the second water pipe 120 and the fourth water pipe 140. In the fully automatic test process of the rain gauge simulating heavy rainfall, the second water stop valve 920 is set to control the opening and closing of the water supply system; the first water stop valve 910 and the third water stop valve 930 are set to control the water outlet status of the first water tank 310 and the second water tank 320 respectively; the water stop valves are set near the box walls of the first water tank 310 and the second water tank 320 so that when it is determined to stop water storage or water supply, they can be shut down as soon as possible to avoid excess water from flowing into the water pipe and causing errors in measuring the water supply; a three-way water pipe is set so that when switching between the first water tank 310 and the second water tank 320, it is only necessary to close the first water stop valve 910 and open the third water stop valve 930 to switch to the second water tank 320 for water supply, or to close the third water stop valve 930 and open the first water stop valve 910 to switch to the first water tank 310 for water supply, thereby avoiding the complicated process of manual switching by pulling out the water pipe when switching the water tanks.

[0055] In some embodiments, the first bearing plate 510 and the second bearing plate 520 are provided with a plurality of holes 1000, and the holes 1000 are used for dredging and draining. During the test of the fully automatic test device for rain gauge simulating heavy rain, the first water storage tank 310 supplies water to the spray plate 700 through the water pump 400 and the water falls into the water receiving port of the rain gauge 600 to be connected. When the rain gauge 600 to be connected completes the corresponding water metering, the measured water will be discharged from the bottom and then discharged through the plurality of holes 1000 of the first bearing plate 510 and the second bearing plate 520, thereby avoiding the accumulation of water on the bearing plate and ensuring that the rain gauge 600 to be connected can work normally without being affected by the accumulated water.

[0056] In some embodiments, a second intelligent water level sensor 820 is provided in the second water tank 320, and the second water tank 320 is provided with a detachable anti-fouling cover (not shown in the figure); when the anti-fouling cover is opened when simulating rainfall through the first water tank 310, the simulated water flows into the second water tank 320 through the hole 1000, and the second intelligent water level sensor 820 is used to provide water volume data flowing into the second water tank 320; when the anti-fouling cover is closed before simulating rainfall through the second water tank 320, the intelligent water level sensor is used to provide water volume data flowing out of the second water tank 320. Specifically, when the first water tank 310 supplies water through the water pump 400, the water measured by the rain gauge 600 to be connected flows out through the hole 1000, the anti-fouling cover of the second water tank 320 is opened, and the water flowing out falls into the second water tank 320 for recycling; the second intelligent water level sensor 820 obtains the water level data of the second water tank 320 in real time; when the second water tank 320 needs to be enabled to supply water, the anti-fouling cover is closed to prevent the water flowing out of the upper hole 1000 from falling into the second water tank 320 again, causing inaccurate water level calculation; the third water valve is opened to start the second water tank 320 to supply water; the second intelligent water level sensor 820 calculates the water supply of the second water tank 320 through the change of the water level. This embodiment recycles and reuses the measured water, effectively reduces the cost of the rain gauge 600 to be connected during the test, and improves the accuracy of the test results by setting the anti-fouling plate.

[0057] In some embodiments, the fully automatic test device for simulating heavy rain also includes a windproof plate (not shown in the figure), which is movably arranged on the vertical surface of the load-bearing frame 200. It can be understood that the test and calibration process of the rain gauge 600 to be connected is often carried out outdoors. When there is wind, it will cause the water passing through the spray plate 700 to fall vertically into the water receiving port of the rain gauge 600 to be connected during the simulated rainfall process, or the water measured by the rain gauge 600 to be connected cannot be efficiently collected when the second water storage tank 320 recovers the water. In order to simulate the ideal state of rainfall and the accuracy of data statistics, a windproof plate is arranged between the first installation layer and the second installation layer of the load-bearing frame 200 and between the second installation layer and the third installation layer. The windproof plate is movably arranged on the vertical surface of the load-bearing frame 200, and the spray plate 700, the rain gauge 600 to be connected, and the second water storage tank 320 and other equipment are completely wrapped up to avoid the influence of measurement and calibration in windy weather, thereby improving the accuracy of measurement. The movable setting of the wind shield may be detachably installed, and when measuring in a windless state, the wind shield may be disassembled and removed to facilitate observation of the measurement process of the rain gauge 600 to be connected.

[0058] In some embodiments, a retractable support rod 1100 is provided between the first installation layer and the second installation layer; the retractable support rod 1100 is used to control the distance between the first installation layer and the second installation layer; and the distance between the first installation layer and the second installation layer is greater than the height of the rain gauge 600 to be connected. The retractable support rod 1100 can be hydraulically retractable, and the height can be adjusted by electric control. When the automatic test device for rain gauges simulating heavy rainfall is tested, the distribution state of raindrops in the simulated rainfall can be changed by adjusting the distance between the spray plate 700 on the first installation layer and the rain gauge 600 to be connected on the second installation layer. Specifically, when the telescopic support rod 1100 is adjusted to make the distance between the spray plate 700 and the water inlet of the rain gauge 600 to be connected closer, the raindrops are concentrated in the central area of ​​the water inlet, resulting in insufficient rainfall received by the edge of the water inlet of the rain gauge 600 to be connected, and the relatively close distance makes the raindrop speed relatively low so that the raindrops remain in a larger water drop shape, and at the same time, the larger raindrops will be broken into smaller raindrops and splashed outside the water inlet of the rain gauge 600 to be connected, which is easy to cause measurement errors; if the distance is moderate, the raindrops will be more evenly distributed on the water inlet of the rain gauge 600 to be connected under the action of gravity and air resistance, so that all parts of the water inlet of the rain gauge 600 to be connected can receive relatively uniform rainfall. By adjusting the telescopic support rod 1100 to change the distance between the two to reach a suitable position, sufficient preparation is made in advance for accurate measurement; and different rain gauges 600 to be connected have different heights, which is also convenient for adapting to the measurement of rain gauges 600 to be connected at different heights.

[0059] In some embodiments, the first water pipe 110 is provided with a pipeline auxiliary valve 1200, and the pipeline auxiliary valve 1200 is used to drain the remaining water in the first water pipe 110 after the simulated rainfall stops. When the fully automatic test device for simulating heavy rainfall completes the measurement work, the water in the first water pipe 110 cannot be completely discharged into the spray plate due to gravity and other reasons. In order to avoid the first water pipe 110 being retained for a long time, resulting in inaccurate data during the next measurement work, the first water pipe 110 is provided with a pipeline auxiliary valve 1200. When the device completes the measurement work, the pipeline auxiliary valve 1200 is opened to drain the water retained in the first water pipe 110 and then the pipeline auxiliary valve 1200 is closed, or the pipeline auxiliary valve 1200 is closed before the next test work is started. Among them, the pipeline auxiliary valve 1200 is set at the position closest to the ground in the first water pipe 110, so as to facilitate the discharge of as much water in the water pipe as possible during the drainage process.

[0060] See also Figure 3As shown, the embodiment of the present application provides a fully automatic calibration device for a rain gauge simulating heavy rainfall, comprising: a load-bearing frame 200, the load-bearing frame 200 comprising a first mounting layer and a second mounting layer, the first mounting layer being located above the second mounting layer; a spray plate 700, the spray plate 700 being movably disposed on the first mounting layer of the load-bearing frame 200; a first load-bearing plate 510, the first load-bearing plate 510 being disposed on the second mounting layer, the first load-bearing plate 510 being used to fix a rain gauge 600 to be connected directly below the spray plate 700; the spraying area of ​​the spray plate 700 being equal to or smaller than the water receiving port area of ​​the rain gauge 600 to be connected; and a first storage Water tank 310, the first water tank 310 is used to supply water to the spray plate 700; water pump 400, one end of the water pump 400 is connected to the water inlet of the spray plate 700 through the first water pipe 110, and the other end of the water pump 400 is connected to the water outlet of the first water tank 310 through the second water pipe 120; control component, the control component is respectively connected to the rain gauge 600 to be connected and the water pump 400, and is used to control the water output and water output speed of the water pump 400, and receive the real-time measurement data of the rain gauge 600 to be connected, and calibrate the rain gauge 600 to be connected according to the water output and water output speed of the water pump 400, as well as the real-time measurement data. Among them, the control component is connected to the rain gauge 600 to be connected and the water pump 400 through communication, and can remotely control the switch of the water pump 400 and the flow rate, so as to simulate heavy rainfall, and timely obtain the metering data of the rain gauge 600 to be connected.

[0061] In some embodiments, the control component is also connected to the first intelligent water level sensor 810, the second intelligent water level sensor 820, the first water stop valve 910, the second water stop valve 920, the third water stop valve 930, the retractable support rod 1100 and the pipeline auxiliary valve 1200 through communication. When it is necessary to switch the water tank, change the rainfall intensity or adjust the height of the retractable support rod 1100 during the test, remote operation can be performed through the control component. When a specific common rainfall intensity is required in the test, the water storage status of the first water tank 310 or the second water tank 320 is first determined by the first intelligent water level sensor 810 or the second intelligent water level sensor 820; when both the first water tank 310 and the second water tank 320 cannot meet the water storage demand, the second water stop valve 920 is controlled to open to supply water to the first water tank 310, and the second water stop valve 920 is closed after the first intelligent water level sensor 810 determines that the water storage is sufficient, and the first water stop valve 910 is opened. And close the third water stop valve 930 to select the first water tank 310 for water supply; when the second water tank 320 meets the water storage demand, the second water tank 320 can also be selected for water supply by closing the first water stop valve 910 and opening the third water stop valve 930; by controlling the length of the retractable support rod 1100, the spray plate 700 and the water receiving port of the rain gauge 600 to be connected are at a suitable distance; by controlling the water pump 400 to start and reach the corresponding flow rate, a specific common rainfall intensity setting is completed. When simulating rainfall, the metering data provided by the rain gauge 600 to be connected is received in real time, and the metering data and water supply data are compared at the end of the test to determine the calibration status of the rain gauge 600 to be connected; after completing the calibration operation, the pipeline auxiliary valve 1200 is opened to release the water in the first water pipe 110 to prepare for the next simulated rainfall.

[0062] In some embodiments, Figure 4 As shown, a camera 1300 is provided on the load-bearing frame 200 above the second installation layer. The camera 1300 provides high-frame-rate video data for analyzing the metering status of the rain gauge 600 to be connected. For example, taking a tipping bucket rain gauge as an example, the camera 1300 is used to shoot the tipping bucket of the tipping bucket rain gauge in real time, record the number of flips of the tipping bucket, and accurately capture the dynamic changes of the rain gauge 600 to be connected during rainfall; the number of flips of the tipping bucket recorded by the camera 1300 is compared with the metering data transmitted in real time by the tipping bucket rain gauge, so as to determine the calibration of the tipping bucket rain gauge. Among them, the camera 1300 can be an industrial camera 1300. By adjusting the shooting angle of the camera 1300, it is also possible to check and determine the placement and connection of each device in the fully automatic test device for simulating heavy rain, so as to avoid interruption of testing or calibration due to improper placement or connection of each device during the experiment.

[0063] In some embodiments, a pressure sensor (not shown in the figure) is installed at the water outlet of the water pump 400, and a flow sensor (not shown in the figure) is installed at the first water pipe 110. The water pump 400 and the retractable support rod 1100 are controlled by the camera 1300 in combination with the simulated rainfall model to achieve different levels of simulated rainfall intensity. For the simulated rainfall model, a regression algorithm and an image classification algorithm may be included. Specifically, firstly, the historical images captured by the camera 1300 under different levels of real rainfall and the parameters of the corresponding levels are collected, and the parameters of the corresponding levels include the precipitation per square meter per hour; the rotation speed of the water pump 400 is gradually adjusted through the sprinkler plate 700 and the pressure value and flow value are recorded, and at the same time, the camera 1300 captures the water flow image of the sprinkler plate 700; the rotation speed of the water pump 400 in the simulated rainfall and the correlation between the pressure value and the flow value are matched according to the precipitation index of the historical image; the rotation speed, pressure value and flow value of the water pump 400, as well as the corresponding rainfall level are used as output labels to train the polynomial regression algorithm, so as to learn how to predict the rainfall level according to the input rotation speed, pressure value and flow value of the water pump 400; the water flow image of the sprinkler plate 700 in the simulated rainfall captured by the camera 1300 is used as the input of the convolutional neural network algorithm, and the rainfall level prediction value obtained by the polynomial regression algorithm is used as a label for training, so as to learn how to identify the rainfall level according to the picture features; the model performance is evaluated through an independent verification data set, and adjustments and optimizations are made according to the verification results to obtain a simulated rainfall model.

[0064] In the actual simulated rainfall process of this embodiment, when the simulated rainfall needs to reach a specific rainfall level, the rotation speed, pressure value and flow value of the water pump 400 are calculated according to the set rainfall level through the polynomial regression algorithm, and then the water pump 400 is automatically controlled by the control component to reach the corresponding state and run. Then the camera 1300 takes a picture of the water flow of the spray plate 700, and the convolutional neural network algorithm is used to identify the rainfall level of the picture and compare it with the set level. If there is a deviation, the parameters of the water pump 400 are adjusted according to the deviation to achieve the desired rainfall level. By simulating the rainfall model, the required simulated rainfall level can be achieved accurately and quickly, which facilitates the execution component to control the simulated rainfall.

[0065] In some embodiments, Figure 5 As shown, the spray plate 700 may include a type a hole type spray plate 700 and a type b needle type spray plate 700. In the process of simulating rainfall, in order to cope with different types of rain gauges 600 to be connected, according to different simulated rainfall requirements, the type of the spray plate 700 is adjusted to change the state of water droplets, thereby adjusting the type of simulated rainfall.

[0066] In some embodiments, Figure 6As shown, the execution component in the fully automatic calibration device for simulating heavy rainfall intensity is also provided with an intuitive network control interface. Through the network control interface, multiple fully automatic calibration devices for simulating heavy rainfall intensity can be controlled and corresponding operations can be performed. Each calibration device can be named as channel one, channel two, etc., and the corresponding calibration device can be selected by naming. The interface includes functional modules such as metering data statistics of the rain gauge 600 to be connected, error statistics, signal connection status prompt, control selection of the retractable support rod 1100, simulated rainfall intensity selection, calibration device selection and measurement mode selection. Among them, in the measurement mode selection module, single means that only one calibration device operates within the calibration time, and synchronization means that multiple calibration devices operate simultaneously within the calibration time.
