Description

Technical Field

[0001] The present invention relates to the field of ecohydrological technology, and in particular to an invisible rainwater automatic collection and observation system. Background Art

[0002] Water is a crucial ecological factor for maintaining healthy ecosystems and the stability of vegetation communities. Besides readily visible sources like rainfall, snowmelt, groundwater, and surface water, vegetation is also replenished by less noticeable "occult precipitation," such as fog, dew, and soil-absorbed water. Studies have shown that occult precipitation plays a crucial role in replenishing vegetation, even surpassing rainfall in certain climate regions. In arid and semi-arid regions, dramatic diurnal temperature swings and relative humidity favor the formation of occult precipitation. In these regions, occult precipitation, often fog and dew, plays a crucial role in maintaining vegetation growth in grasslands and windswept sandy areas. It also serves as a crucial source of water for certain small animals, insects, and soil crusts. In water-scarce arid and semi-arid regions, occult precipitation plays a crucial role in the transformation of different water bodies and the water cycle.

[0003] Condensation refers to water that condenses on the ground or surfaces during clear, calm or light nights or early mornings. This occurs when the air temperature near the ground or surface drops below the dew point due to radiative cooling. Currently, the collection and observation of invisible rainfall is primarily manual, resulting in high time and labor costs. Invisible rainfall primarily forms at night and early morning, making manual collection and continuous observation even more challenging in arid and semi-arid regions. In sparsely populated deserts and grasslands, where living conditions are poor and wildlife frequent the area, communication conditions are poor, and worker safety is particularly challenging at night, making long-term, continuous field observation data impossible and subject to significant errors. Furthermore, arid and semi-arid regions are subject to strong winds and unpredictable weather. Open-air data collection is susceptible to the influence of other factors (sand, weeds, and rainfall), resulting in significant sample errors. These factors can significantly impact research on the formation process, isotopic composition, and water cycle of invisible rainfall.

[0004] Therefore, for arid and semi-arid areas, how to provide an invisible rainfall collection and real-time monitoring system that does not require manual operation and avoids the influence of external factors as much as possible has become an urgent problem to be solved.

[0033] The present invention will be described in further detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0034] like Figures 1 to 6 As shown, an embodiment of the present invention provides an automatic invisible rainwater collection and observation system, comprising: a bracket 1; a collection plate 2, which is arranged above the bracket 1 and supported by the bracket 1, the collection plate 2 having a V-shaped cross-section, one side of the collection plate 2 being higher and the other side being lower, and a drain outlet 23 being formed at the lowest point of the collection plate 2; a top cover 3, which is arranged on the top of the bracket 1 and covers the top of the collection plate 2; a collector, which is arranged below the collection plate 2 and communicates with the collection plate 2 through the drain outlet 23, and is used to collect invisible rainwater collected by the collection plate 2; a quality detection module 12, which is used to monitor the quality of the invisible rainwater collected by the collector; a processor 16, which is connected to the quality detection module 12 and is used to receive the quality of the invisible rainwater monitored by the quality detection module 12 and determine the flow rate of the invisible rainwater based on the quality of the invisible rainwater monitored by the quality detection module 12 and the monitoring time; and a remote server, wherein the processor 16 communicates with the remote server via a signal transmission module and sends the flow rate of the invisible rainwater to the remote server.

[0035] The invisible rainwater automatic collection and observation system provided by the present invention comprises a collection device and a data collection and transmission device. The collection device is composed of a bracket 1, a collection plate 2, a top cover 3 and a collector.

[0036] The collection plate 2 serves as a panel for collecting invisible rainwater (including dew and fog water). Its cross-section is V-shaped, that is, the collection plate 2 is a V-shaped structure formed by splicing two plates. Under the support of the bracket 1, the collection plate 2 is in a state where one side is high and the other side is low, so that the two plates form two slopes, and a drain outlet 23 is formed at the lowest point of the collection plate 2. When in use, the invisible rainwater condensed on the surface of the plate will flow along the surface of the plate under the action of gravity until it flows to the connection between the two plates, and then flows along the connection to the drain outlet 23, and is finally collected by the collector. Here, the slopes of the two plates can be appropriately adjusted according to the speed of invisible rainfall formation and the amount of water in different regions.

[0037] In a preferred embodiment, the collection plate 2 is made of a multilayer material, comprising, from top to bottom, a polytetrafluoroethylene (PTFE) membrane 4, a wire mesh 5, and a foam sheet 6. The PTFE membrane 4 facilitates condensation of dew and fog on its surface, and a 0.5 x 0.5 m PTFE membrane 4 can be used as the topmost layer of the collection plate 2. A V-shaped wire mesh 5 is placed beneath the PTFE membrane 4, and beneath that, the foam sheet 6, both arranged in a V-shape. The foam sheet 6 serves to isolate the PTFE membrane 4 from heat radiation from the ground at night, while the wire mesh 5 facilitates air circulation between the membrane and the foam sheet 6, thereby providing a cooling effect.

[0038] The collection plate 2 is placed on the bracket 1. The bracket 1 also has a V-shaped cross-section, with one side higher and one side lower in the longitudinal direction. This creates a slope between the two panels of the collection plate 2, allowing invisible rainfall to flow into the collection bottle 19 under the action of gravity. The bracket 1 has six fixing posts 7 at its lower portion: two on each side (i.e., one at each outer corner of the two panels). One is located at the highest point of the bottom of the collection plate 2 (i.e., the highest point of the connection between the two panels), and no fixing post 7 is located at the lowest point of the bottom of the collection plate 2 (i.e., the lowest point of the connection between the two panels). The lower fixing post 7 is positioned relatively inward to allow space for the drainage outlet 23 and the collection bottle 19. A windproof bucket 21 for accommodating the collection bottle 19 can also be secured to the fixing posts 7. The fixing posts 7 need to be buried in the soil to provide a secure fit. For hard soil, holes can be drilled in the top of the fixing posts 7 for rivet fastening. In softer desert soil, the fixing posts 7 need to be lengthened to allow the bracket 1 to be buried deeper. The bracket 1 is preferably implemented by an iron bracket 1. In order to consider the safety of the instrument, a lightning rod 17 is also arranged and installed on the top of the processor fixing rod 24.

[0039] In a preferred embodiment, the top cover 3 is in an inverted V-shape and made of PVC. It covers the bracket 1 and the collection plate 2. PVC is highly resistant to temperature and light, allowing for long-term use. The inverted V-shape facilitates drainage of rainwater during rainy days. A top cover 3 is provided above the bracket 1 and can be secured to the upper frame of the bracket 1. The top cover 3 and the bracket 1 are connected via iron posts. The width of the top cover 3 is longer than that of the bracket 1, covering the bracket 1 and the collection plate 2 and preventing rainwater or other water sources from entering the collection plate 2.

[0040] In a preferred embodiment, the upper part of the side surface between the top cover 3 and the lowest side of the collecting plate 2 is closed by a nylon mesh 10, the lower part of the side surface between the top cover 3 and the lowest side of the collecting plate 2 is hollowed out to observe the invisible rainfall collection situation, and the space between the other three side surfaces between the top cover 3 and the collecting plate 2 is completely closed by the nylon mesh 10.

[0041] Specifically, the space between the top cover 3 and the collection plate 2 is sealed on all sides with nylon mesh 10. The space between the top cover 3 and the other four sides of the collection plate 2 is completely enclosed by the nylon mesh 10. A gap is left only on the lower side of the bracket 1. Specifically, the upper portion of the space between the top cover 3 and the two lowest sides of the collection plate 2 is enclosed by the nylon mesh 10. The lower portion of the space between the top cover 3 and the two lowest sides of the collection plate 2 is hollowed out. The hollowed-out portion 11 facilitates observation of the collection progress on the collection plate 2. The nylon mesh 10 not only prevents weeds and other materials from entering the collection plate 2, but also ensures adequate air circulation, preventing damage to the instrument from strong winds. Furthermore, the nylon mesh 10 slows air velocity above the collection plate 2, reducing evaporation losses from invisible rainfall. The mesh size of the nylon mesh 10 can be adjusted based on local wind speeds and other conditions. Furthermore, the top cover 3 frame is equipped with a fixing buckle 8, which is connected to the ground via a wire 9 to strengthen the instrument's stability.

[0042] In a preferred embodiment, the system further comprises a pulley 18 assembly, the pulley 18 assembly comprising a pulley 18 and a rope slidably wound around the pulley 18, the pulley 18 being rotatably disposed on the bracket 1; the collector comprising a plurality of collecting bottles 19, the plurality of collecting bottles 19 being disposed on the rope, after one of the collecting bottles 19 is filled with invisible rainwater, moves downward under the action of gravity, and drives the rope to slide along the pulley 18, so that another empty collecting bottle 19 moves to below the drain outlet 23.

[0043] Specifically, a collector is installed at the lowest point of the support 1. A pulley 18 is installed at the lowest point of the support 1. A rope is wound around pulley 18 and connected to a collection bottle 19 via rope 20. The center of the bottle opening is vertically aligned with the drain outlet 23 of the collection plate 2, allowing dew, fog, and other water to flow freely into the bottle 19. The bottle 19 can be suspended from the rope, with sufficient space left between the pulley 18 and the collection plate 2 to allow the bottle 19 to pass through the space between the pulley 18 and the collection plate 2. When a bottle 19 is filled with sample, gravity causes the filled bottle 19 to move downward, driving the rope 20 along the pulley 18. The empty bottle moves below the drain outlet 23 to continue collecting rainwater, and the cycle repeats. N sampling bottles are arranged on the rope 20, preferably an odd number, to ensure symmetrical sampling around the pulley 18. The number of bottles 19 can be determined based on preliminary surveys of the amount of invisible rainfall and can be increased or decreased based on actual conditions.

[0044] In a preferred embodiment, the multiple collection bottles 19 are placed within a windproof barrel 21; the mouths of the collection bottles 19 are equipped with a permeable membrane 22. The collection bottles 19 and their ropes are placed within the windproof barrel 21 to prevent wind disturbances and minimize water sample loss. The permeable membrane 22 at the mouths of the collection bottles filters invisible rainfall, preventing weeds and windblown sand from entering the collection bottles 19 and ensuring the purity of the collected water samples. Furthermore, the permeable membrane can, to a certain extent, prevent secondary evaporation of dew and other substances from the collection bottles 19. The collection bottles 19 can be made of plexiglass, which has good chemical stability and weather resistance.

[0045] Furthermore, the data acquisition and transmission device includes a solar panel 15, a battery 13, a microprocessor, a transmission chassis 16, a temperature sensor 14, and a signal transmission module. The microprocessor is arranged inside the transmission chassis, and the transmission chassis 16 can provide protection for the microprocessor. The transmission chassis is fixedly arranged on the upper part of the processor fixing rod 24. The signal transmission module is also arranged inside the transmission chassis, and the signal transmission module is connected to the microprocessor. The quality detection module 12 and the temperature sensor 14 are respectively connected to the signal transmission line and connected to the microprocessor. The signal transmission line extends to the inside of the transmission chassis and is connected to the microprocessor. The monitoring data of the quality detection module 12 and the temperature sensor 14 is transmitted to the microprocessor, and then reaches the remote server through the signal transmission module, realizing the automatic collection and continuous observation of invisible rainfall without manual operation. The signal transmission module can be a 4G / Beidou transmission module.

[0046] In a preferred embodiment, in the invisible rainwater automatic collection and observation system, the quality detection module 12 is arranged at the center position of the pulley 18, and is used to increase the mass of the invisible rainwater collected by the collector by one mass unit whenever a collection bottle 19 is filled with invisible rainwater, and the mass unit is the mass of the invisible rainwater collected by a single collection bottle 19; the processor 16 is used to record a monitoring time every time the mass of the invisible rainwater monitored by the quality detection module 12 increases by one mass unit, and determine the monitoring time according to the most recently recorded monitoring time and the monitoring time when the collector starts collecting.

[0047] Specifically, assuming that the mass of rainwater that a collection bottle 19 can hold is m, then one mass unit is m. That is, when a sampling bottle completes collection, the mass monitored by the quality detection module 12 should increase by m. Every time the quality detection module 12 increases by m, the microprocessor 16 counts once and records the time once. The monitoring duration can be determined based on the recorded time, that is, based on the monitoring time when the collector starts collecting and the monitoring time of the most recent record, the monitoring duration between the two monitoring times can be calculated. The flow rate of invisible rainfall can be determined by dividing the mass monitored by the current quality detection module 12 by the monitoring duration. For example, based on the monitoring time when the collector starts collecting and the monitoring time recorded when the last collection bottle 19 is full, the time t when all the collection bottles 19 are full can be calculated. Then, the invisible rainwater mass m*n filled by all the collection bottles 19 is divided by the time t to obtain the flow rate c of the invisible rainwater.

[0048] In a preferred embodiment, the processor 16 is used to count once each time the mass of the invisible rainwater monitored by the quality detection module 12 increases by one mass unit, and to send a collection warning prompt to the remote server when the count reaches n-1, where n is the number of the collection bottles 19.

[0049] Specifically, when the count reaches n-1 times, the microprocessor 16 prompts the remote server to issue a collection warning, prompting the staff to collect samples in a timely manner.

[0050] In a preferred embodiment, the system further includes a temperature sensor 14, which is arranged near the surface and is used to monitor the ambient temperature near the surface; the processor 16 is connected to the temperature sensor 14, and is used to receive the ambient temperature near the surface monitored by the temperature sensor 14, and send the ambient temperature near the surface to a remote server.

[0051] Temperature is an important factor in the formation of dew and fog. Therefore, a temperature sensor 14 is placed near the surface to monitor the ambient temperature near the surface. The monitoring data of the temperature sensor is transmitted in real time through the signal transmission module.

[0052] In a preferred embodiment, in the invisible rainwater automatic collection and observation system, the system further includes a solar panel 15 and a battery 13, and the solar panel 15 and the battery 13 supply power to the system through a power supply line.

[0053] Specifically, the quality detection module 12, the processor 16, and the temperature sensor 14 can all be connected to the battery 13 via a power line and operate under the power supply of the battery 13. The solar panel 15 can be electrically connected to the battery 13 to supply power to the battery 13.

[0054] To sum up, the invisible rainwater automatic collection and observation system provided by the embodiment of the present invention can work continuously under different climatic conditions, and is used to observe the near-ground temperature and the automatic collection of invisible rainfall such as fog and dew. The monitored data and test data can be transmitted to the remote server in a timely manner, effectively improving the accuracy and completeness of the collected data, greatly saving the cost of manual observation, and the high-precision and high-frequency monitoring data provided are more conducive to the analysis of condensation water.

[0055] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and exemplary embodiments. They can be applied to a variety of fields suitable for the present invention. Further modifications will be readily apparent to those skilled in the art. Therefore, the present invention is not limited to the specific details and illustrations shown and described herein without departing from the general concept defined by the claims and their equivalents.
