Description

Technical Field

[0001] The present invention relates to the technical field of water ecological environment monitoring, and specifically to a prediction and early warning system and method for the ecological risks of river and lake waters caused by climate change. Background Art

[0002] As global climate change intensifies, factors such as rising temperatures, changes in precipitation patterns, and frequent extreme climate events are profoundly affecting the structure and function of river and lake ecosystems. These changes not only alter the physical, chemical, and biological characteristics of river and lake ecosystems, but also lead to increasing water ecological risks. Therefore, it is particularly important to accurately predict and promptly warn of river and lake water ecological risks under climate change conditions. To achieve prediction and early warning of river and lake water ecological risks based on climate change, it is necessary to collect meteorological data (such as temperature, precipitation, wind speed, etc.) and water ecological parameters (such as pH value, dissolved oxygen content, nutrient concentration, plankton count, etc.) for comparison and assessment of the risk level faced by river and lake ecosystems under different climate change conditions.

[0003] In actual operation, monitoring devices are usually set up on the banks of rivers and lakes, and the necessary water ecological parameters are obtained by using the detection equipment (lidar, acoustic Doppler current profiler, etc.) and probes (probes equipped with temperature sensors, turbidity sensors, pH sensors, etc.) on the monitoring devices;

[0004] However, the application of existing probes has obvious limitations. If the probe is fixedly installed, when the water level of rivers and lakes changes significantly, the depth of the probe in the water will change or it will emerge from the water surface; if the probe is installed on a buoy, although the buoy can float up and down with the change of water level to ensure that the probe is always below the water surface, a sufficiently long cable must be left for the buoy to move up and down (the cable is connected to the probe). When the water level of rivers and lakes changes, the probe will not only move up and down with the buoy, but also move with the direction of water flow, causing it to easily deviate from the original monitoring area, affecting the reliability and accuracy of digital water ecological data collection, and affecting the operation of the prediction and early warning system. Summary of the Invention

[0005] The purpose of the present invention is to provide a prediction and early warning system and method for the ecological risks of river and lake waters caused by climate change, so as to solve the problem that the application of the detection probe on the monitoring device proposed in the above background technology has obvious limitations.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a prediction and early warning system for the impact of climate change on the water ecology of rivers and lakes, comprising: a column, on which a central control device, a meteorological detection device, an alarm, and a water ecology detection device are installed; the central control device is connected to a detection probe via a cable; the water ecology detection device and the detection probe are used to obtain water ecology parameters; the meteorological detection device is used to detect meteorological data; the central control device assesses the risk level faced by the river and lake ecology under different climate change conditions based on the obtained water ecology parameters and meteorological data, and controls the alarm to sound an alarm when the risk level exceeds a threshold;

[0007] The cable is provided with a floating part and a storage box, and the storage box is provided with a storage component. The central control device is used to control the operation of the storage component when a water level change is detected, so that the external cable enters the storage box or releases the cable in the storage box to the outside.

[0008] Preferably, the storage assembly includes two guide rollers arranged in the storage box, a first driving member arranged in the storage box, and a supporting member arranged on the moving end of the first driving member, and the supporting member is sleeved on the outside of the cable.

[0009] Preferably, there are two first driving members and two supporting members, and the two first driving members are distributed in sequence along the length extension direction of the cable. A second driving member for driving one first driving member to move is provided in the storage box.

[0010] Preferably, the support comprises a frame and guide wheels provided on the frame.

[0011] Preferably, a sleeve is provided on the cable, and a roller for supporting the cable is provided in the sleeve.

[0012] Preferably, a telescopic rod is hinged between the kit and the floating member.

[0013] Preferably, an annular plate is rotatably provided on the floating member, a mounting ring is rotatably provided on the kit, and both ends of the telescopic rod are hinged to the annular plate and the mounting ring respectively.

[0014] Preferably, a barrier is provided on the side wall of the floating member;

[0015] Wherein, the blocking member includes an elastic telescopic rod and a stopper provided on the movable end of the elastic telescopic rod.

[0016] Preferably, a method for predicting and warning the ecological risks of river and lake waters due to climate change, using the above-mentioned prediction and warning system for the ecological risks of river and lake waters due to climate change, comprises the following steps:

[0017] S1: Water ecological detection equipment and detection probes collect water ecological parameters, and meteorological detection equipment collects meteorological data. The central control equipment assesses the risk level faced by river and lake ecology under different climate change conditions based on the collected water ecological parameters and meteorological data. When the risk level exceeds the threshold, the alarm is controlled to sound an alarm.

[0018] S2: When the central control device detects a change in water level, it controls the storage component to operate. When the water level rises, the external cables are stored inside the storage box. When the water level drops, the cables in the storage box are released to the outside.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. When a change in river or lake water level is detected, the central control device controls the storage component to operate, allowing external cables to enter the storage box or release the cables in the storage box to the outside, so that the detection probe does not appear above the water surface. At the same time, the detection probe is ensured not to leave the area where it is located, ensuring that the detection probe is always in the water, making the collection of water ecological parameters more accurate and reliable, and ensuring the stable operation of the prediction and early warning system;

[0021] 2. The telescopic rod can provide a supporting force for the floating part, resisting its movement with the water flow, while reducing the pulling force generated by the water flow on the cable and the detection probe, protecting the cable, and ensuring that the detection probe will not leave the detection area, making the water ecological data collected more accurate and ensuring the accuracy of the prediction and early warning system.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Example 1

[0029] See also Figure 1 A prediction and early warning system for the ecological risks of river and lake waters due to climate change includes: a column 1 fixed to the bank of a river or lake, a central control device 2 installed on the side wall of the column 1, which can be a computer, and a meteorological detection device 3 installed on the top of the column 1. The meteorological detection device 3 is used to detect temperature (daily average temperature, maximum / minimum temperature), precipitation (precipitation amount, precipitation intensity, precipitation duration), wind speed and direction (average wind speed, maximum wind speed, dominant wind direction), sunshine (sunshine hours, solar radiation intensity (W / m 2 )), humidity (relative humidity, absolute humidity), evaporation, the equipment for detecting the above parameters belongs to the existing equipment and will not be described in detail here. An alarm 4 is installed on the column 1, and a water ecological detection device 5 is installed on the top of the column 1. The central control device 2 is connected to the detection probe 7 through a cable 6. The water ecological detection equipment 5 detects water ecological parameters from the outside of the water. The detection probe 7 is inserted into the water to detect water ecological parameters. Water ecological parameters include water temperature, water depth / water level, flow rate / flow, turbidity / transparency, dissolved oxygen, pH value, nutrients, heavy metals, organic pollutants, chlorophyll a (Chl-a), and the water ecological detection equipment 5 includes laser radar, acoustic Doppler flow profiler and other equipment for detecting water ecological parameters from the outside of the water. This equipment belongs to the existing technology and will not be described in detail here. The detection probe 7 is equipped with multiple sensors, including temperature sensors, turbidity sensors, pH sensors, dissolved oxygen sensors and other equipment, which are used to detect water ecological parameters from water. This equipment also belongs to the existing technology.

[0030] It should be noted that photovoltaic equipment is installed on the column 1 to generate electricity using solar energy and supply power to the equipment on the prediction and early warning system.

[0031] See also Figure 1 、 Figure 2 and Figure 3 , a floating member 8 (such as an air bag, a buoy) is provided on the outer wall of the cable 6, a storage box 9 is provided on the outer wall of the cable 6, and a storage component is provided inside the storage box 9;

[0032] Among them, the storage assembly includes two guide rollers 17, a first driving member 10 (such as an electric telescopic rod) and a support 18 provided on the moving end of the first driving member 10; the two guide rollers 17 are rotatably installed in the inner cavity of the storage box 9, the first driving member 10 is installed in the inner cavity of the storage box 9, and the support 18 is sleeved on the outer wall of the cable 6.

[0033] It should be noted that during the use of the prediction and warning system, the float 8 floats on the water surface and the detection probe 7 is in the water. By changing the position of the float 8 on the outer wall of the cable 6, the depth of the detection probe 7 in the water can be adjusted; the storage box 9 is fixed on the shore; a fixing hoop is installed on the side wall of the storage box 9 close to the column 1, and a rubber pad is installed on the inner side of the fixing hoop, and the cable 6 on the side of the storage box 9 close to the column 1 is fixed by the fixing hoop.

[0034] A method for predicting and warning the ecological risks of rivers and lakes due to climate change, comprising the following steps:

[0035] First, the water ecological detection equipment 5 and detection probes 7 collect water ecological parameters of river and lake water, and the meteorological detection equipment 3 collects meteorological data. The central control device 2 receives the water ecological parameters and meteorological data, pre-processes them (to ensure data quality and consistency), compares the two data, and sets thresholds to assess the risk level faced by river and lake ecosystems under different climate change conditions. When the risk level exceeds the threshold, the alarm device 4 is controlled to sound an alarm.

[0036] Second, during the use of the prediction and early warning system, when the central control device 2 detects a change in water level based on the data collected by the water ecological detection equipment 5, it will control the first drive member 10 of the storage component to work and retract. When the water level of the river or lake rises, the first drive member 10 contracts, causing the support member 18 to move the cable 6 closer to the guide roller 17, causing the cable 6 to bend inside the storage box 9, and the external cable 6 to be stored inside the storage box 9. When the water level drops, the first drive member 10 extends, moving the support member 18 in the opposite direction, to release the cable 6 in the storage box 9 to the outside, ensuring that the detection probe 7 will not be exposed to the water surface, and at the same time, it will not leave the pre-monitored area.

[0037] It should be noted that when the prediction and warning system is installed and used, after the detection probe 7 is placed in the water, the storage box 9 is fixed to the shore, and then the storage component is controlled to work, the length of the cable 6 inside the storage box 9 is changed, so that the position of the detection probe 7 is adjusted to the predetermined position; during the use of the prediction and warning system, the central control device 2 adjusts the extension and retraction length of the first driving member 10 according to the specific value of the river and lake water level change, so as to control the length of the cable 6 to be stored or released; Figure 3 The diagram shows the cable 6 in a stretched state, indicating that the storage box 9 has completely released the cable 6 .

[0038] In this embodiment, as a further optimization solution, please refer to Figure 2 and Figure 3 There are two first driving members 10 and two supporting members 18. The two first driving members 10 are distributed in sequence along the length extension direction of the cable 6. A second driving member 16 (such as an electric telescopic rod) is installed in the inner cavity of the storage box 9. The moving end of the second driving member 16 is connected to one first driving member 10 (the second driving member 16 is connected to the first driving member 10 on the right); the first driving member 10 is driven to move by the second driving member 16 (moving along the length extension direction of the cable 6), so that the cable 6 moves to the right side of the right guide roller 17, so that the bending amplitude of the cable 6 inside the storage box 9 is increased again, thereby increasing the ability of the storage box 9 to store the cable 6.

[0039] In this embodiment, as a further optimization solution, please refer to Figure 3 The support 18 includes a frame 181 and a guide wheel 182 rotatably arranged on the frame 181. The frame 181 is installed on the movable end of the first driving member 10, and the guide wheel 182 is in contact with the cable 6. When the support 18 pulls the cable 6 to move, the guide wheel 182 will rotate to guide the cable 6, so as to reduce the friction resistance between the cable 6 and the guide wheel 182 and reduce the wear of the cable 6.

[0040] Example 2

[0041] As a further optimization solution of Example 1, please refer to Figure 2 A kit 11 is provided on the cable 6, and the side of the kit 11 away from the floating member 8 is connected to the storage box 9. A roller 12 is provided in the inner cavity of the kit 11, and the roller 12 is in contact with the cable 6 for supporting the cable 6. The cable 6 is guided when it is stored or released by the rotation of the roller 12, thereby reducing the chance of wear of the cable 6.

[0042] In this embodiment, as a further optimization solution, please refer to Figure 2 and Figure 4 A ring plate 14 is rotatably provided on the side wall of the floating member 8 facing the kit 11, and a mounting ring 19 is rotatably provided on the outer wall of the kit 11. A telescopic rod 13 is hinged between the ring plate 14 and the mounting ring 19 (the telescopic rod 13 includes a telescopic mother rod and a telescopic child rod slidably inserted in the inner cavity of the telescopic mother rod). The two ends of the telescopic rod 13 are hinged to the ring plate 14 and the mounting ring 19 respectively through a rotating shaft. There are two telescopic rods 13; when the floating member 8 floats on the water surface and the detection probe 7 is in the water, the two telescopic rods 13 are respectively located on the left and right sides of the cable 6, and the telescopic rod 13 can only swing up and down at the kit 11, and the floating member 8 can only swing up and down at the end of the telescopic rod 13, so that the telescopic rod 13 can provide a supporting force for the floating member 8, resisting its movement with the water flow, and at the same time reducing the pulling force generated by the water flow on the cable 6 and the detection probe 7.

[0043] In this embodiment, as a further optimization solution, please refer to Figure 2 A barrier 15 is provided on the side wall of the floating member 8 facing the river or lake shore; the barrier 15 includes an elastic telescopic rod 151 (the elastic telescopic rod 151 includes a telescopic mother rod, a telescopic sub-rod slidably inserted in the inner cavity of the telescopic mother rod, and a spring provided between the telescopic mother rod and the telescopic sub-rod) and a stopper 152 provided on the movable end of the elastic telescopic rod 151; the barrier 15 is used to block and prevent the floating member 8 from approaching the shore, and to prevent the detection probe 7 from being exposed to the water surface, thereby ensuring that it can normally collect water ecological parameters.
