Description

Technical Field

[0001] The present application relates to the technical field of water ecological simulation experimental devices, and in particular to an ecological effect simulation system based on a river network and a control method thereof. Background Art

[0002] River networks are important ecosystems, and their connectivity (including vertical, lateral, vertical, and temporal dimensions) is crucial for maintaining the structure and function of river ecosystems. Studying the regulation of river network connectivity and its ecological effects is of great significance for river ecological protection, water resource management, and water pollution prevention and control.

[0003] Methods for studying the ecological effects of river networks primarily include field observations and laboratory simulations. While field observations can reflect real-world conditions, they are complex, difficult to precisely control and isolate, and require long and costly cycles. Traditional laboratory simulations (such as using a single flume or a simple array of parallel flumes), while highly controllable, often struggle to replicate the complex hierarchical structure and multi-scale characteristics of real river networks. Summary of the Invention

[0004] In view of this, the present application provides an ecological effect simulation system and control method based on a river network, which can simulate the ecological effects of the river network with high simulation realism and low cost.

[0006] In one possible implementation, the water supply device is used to supply water to the uppermost water tank, and the ecological effect simulation system also includes a wastewater recovery device; the wastewater recovery device is connected to the lowermost water tank, and the wastewater recovery device is used to recover water flowing out of the lowermost water tank.

[0007] In one possible implementation, the water supply device is used to supply water to the top water tank, and the ecological effect simulation system also includes a water pump device; the water pump device is connected to the bottom water tank, and the water pump device is used to pump water flowing out of the bottom water tank into the top water tank.

[0008] In one possible implementation, the water supply device includes a first flow control valve arranged at the water inlet of each of the top water tanks, and the ecological effect simulation system also includes a control device; the control device is communicatively connected to the first flow control valve, and the control device is used to control the valve opening of each of the first flow control valves to control the water flow rate when the water in the water supply device flows into the top water tank.

[0009] In one possible implementation, the connecting pipe includes a second flow control valve; the second flow control valve is communicatively connected to the control device, and the control device is used to control the valve opening of the second flow control valve to control the water flow rate when the water in the second water tank flows into the first water tank.

[0010] In one possible implementation, the ecological effect simulation system also includes a water filtration device; the water filtration device is connected between the water supply device and the top water tank, and the water filtration device is used to filter the water from the water supply device and transmit it to the top water tank.

[0011] In a possible implementation, the first water tank is connected to M second water tanks through the connecting pipe, where M is an integer greater than 1; and the capacity of the first water tank is M times that of the second water tanks connected thereto.

[0012] In a second aspect, an embodiment of the present application also provides a river network-based ecological effect simulation system control method, which is applied to the aforementioned ecological effect simulation system; the method includes: controlling the water supply device to supply water to the uppermost water tank or the lowermost water tank.

[0013] In a possible implementation, the method further includes: while controlling the water supply device to supply water to the uppermost water tank, separately controlling the water flow rate and the total water volume flowing into each of the uppermost water tanks.

[0014] In a possible implementation, the method further includes: separately controlling a water flow rate of water in each of the second water tanks when the water flows into the first water tank.

In other words, the height difference between the water troughs at adjacent levels allows water in the water trough at the higher level to automatically flow into the water trough at the lower level due to the height difference, thereby simulating the hierarchical structure and multi-scale characteristics of the river network and ensuring the fidelity of the river network simulation by the ecological effect simulation system. By arranging the number of second water troughs at the higher level to be greater than the number of first water troughs at the lower level, and providing at least two second water troughs connected to the first water troughs via independent connecting pipes, the hierarchical structure and multi-scale characteristics of the river network are further simulated, thereby further improving the fidelity of the river network simulation by the ecological effect simulation system.

[0026] River networks, also known as river networks, are complex water systems formed by interconnected main rivers, tributaries, and various levels of waterways. They are of great significance in physical geography, ecology, and technology. River networks typically exhibit a dendritic structure, consisting of a main stream, multiple tributaries, and capillary channels, similar to the human vascular system.

[0027] Please refer to Figure 1 , Figure 1 This is a schematic diagram of the functional modules of the river network-based ecological effect simulation system of this application. For ease of explanation, the functional module diagram of the ecological effect simulation system only shows the parts relevant to the embodiments of this application. Those skilled in the art will understand that the illustrated structure does not constitute a limitation of the system, and it may include more or fewer components than shown, or combine certain components, or arrange the components differently.

[0028] The ecological effect simulation system 100 includes a water tank 101, a connecting pipe 102, and a water supply device 103. The water tank 101 includes N levels. In the vertical direction, the first height of the first water tank located on the i-th level in the water tank 101 from the horizontal plane is less than the second height of the second water tank located on the i+1-th level from the horizontal plane, where N is an integer greater than 2, i is any integer between 1 and N-1, and the number of second water tanks is greater than the number of first water tanks. Each first water tank is connected to at least two second water tanks via a connecting pipe 102, where each second water tank is connected to the first water tank via an independent connecting pipe 102. The water supply device 103 is used to supply water to the top water tank on the N-th level, or to supply water to the bottom water tank on the 1st level.

[0029] Specifically, Figure 1 In the ecological effect simulation system 100 shown, the water tanks 101 include six levels, and the number of water tanks 101 decreases from 32 in the highest level (i.e., the 6th level): 16 water tanks 101 in the 5th level, 8 water tanks 101 in the 4th level, 4 water tanks 101 in the 3rd level, 2 water tanks 101 in the 2nd level, and 1 water tank 101 in the 1st level. Figure 1 As can be seen in the figure, water supply device 103 supplies water to water tank 101 on the sixth level. Furthermore, for two adjacent levels, the two water tanks 101 on the higher level are connected to a water tank 101 on the lower level via independent connecting pipes 102. This arrangement allows water tank 101 on the sixth level to simulate the source stream, while water tank 101 on the first level simulates the main stream outlet, ensuring the authenticity of ecological effects simulation system 100 in simulating the ecological effects of the river network.

[0030] It should be noted that this embodiment does not specifically limit the number of water tanks 101 at each level and the connection relationship between water tanks at adjacent levels. It can be set according to the actual situation of the river network that needs to be simulated, thereby ensuring the authenticity of the simulation of the ecological effects of the river network.

[0031] In some embodiments, the first water tank is connected to M second water tanks through connecting pipes, wherein M is an integer greater than 1; the capacity of the first water tank is M times that of the second water tank connected to it. Figure 1Taking the ecological effect simulation system 100 shown in the figure as an example, M is set to 2. Assuming that the capacity of the water tank 101 on the 6th level is 10L, the capacity of the water tank 101 on the 5th level is 20L, the capacity of the water tank 101 on the 4th level is 40L, the capacity of the water tank 101 on the 3rd level is 80L, the capacity of the water tank 101 on the 2nd level is 160L, and the capacity of the water tank 101 on the 1st level is 320L. This ensures that after water in the second water tank on the higher level flows into the first water tank on the lower level, the water in the first water tank will not overflow, thereby improving the reliability of the ecological effect simulation system 100.

[0032] In some embodiments, the connecting pipe 102 is detachable, allowing researchers to easily change the water flow path and connection strength between adjacent levels of water tanks, thereby regulating the connectivity structure of the river network and further improving the authenticity of the simulation of the ecological effects of the river network.

[0033] In some embodiments, the ecological effect simulation system 100 further includes a wastewater recovery device (not shown). When the water supply device 103 is used to supply water to the water tanks 101 located on the sixth level (i.e., the topmost water tank), the wastewater recovery device is connected to the water tanks 101 located on the first level (i.e., the bottommost water tank) and is used to recover water flowing out of the water tanks 101 located on the first level. During actual river network ecological effect simulations, nutrients and other chemical substances may be added to the water supply device 103 to ensure that the water quality of the water in the water supply device 103 matches that of the source streams in the actual river network, thereby further enhancing the authenticity of the river network ecological effect simulation. Therefore, the wastewater recovery device in this embodiment prevents water from the water tanks 101 located on the first level from flowing back into the water tanks 101 located on the sixth level, thereby affecting the simulation of the river network ecological effects and thereby improving the reliability of the ecological effect simulation system 100.

[0034] In some embodiments, the ecological effect simulation system further includes a water pump device (not shown). When the water supply device is used to supply water to the water tank 101 located on the 6th floor, the water pump device is connected to the water tank 101 located on the 1st floor. The water pump device is used to pump water flowing out of the water tank 101 located on the 1st floor into the water tank 101 located on the 6th floor, thereby realizing water recycling to reduce water resource consumption.

[0035] In some embodiments, the water supply device 103 includes a first flow control valve arranged at the water inlet of each water tank 101 located on the 6th floor, and the ecological effect simulation system 100 also includes a control device; the control device is communicatively connected to the first flow control valve, and the control device is used to control the valve opening of each first flow control valve to control the water flow rate when the water in the water supply device 103 flows into the water tank 101 located on the 6th floor.

[0036] Specifically, the first flow control valve may be a solenoid valve. By controlling the valve opening of the first flow control valve, the ecological effect simulation system 100 can simulate the ecological effect of the river network more realistically.

[0037] In some embodiments, the connecting conduit 102 includes a second flow control valve; the second flow control valve is in communication with a control device, which is configured to control the valve opening of the second flow control valve to control the flow rate of water in the second water tank when it flows into the first water tank. As can be seen from the description of the aforementioned embodiment, the second water tank is the water tank 101 located at a higher level among adjacent levels, and the first water tank is the water tank 101 located at a lower level among adjacent levels. By providing the second flow control valve, the valve opening of the second flow control valve can be controlled to change the topology and water flow distribution of the ecological effect simulation system 100, thereby enabling the ecological effect simulation system 100 to more realistically simulate the ecological effects of the river network.

[0038] In some embodiments, the ecological effect simulation system 100 further includes a water filtration device connected between the water supply device 103 and the water tank 101 on the sixth level, and the water filtration device is used to filter the water from the water supply device 103 and transmit it to the water tank 101 on the sixth level.

[0039] Specifically, the water flowing out of the water supply device 103 is pre-treated by sand filtration, activated carbon filtration, etc. before flowing into the 6th-level water tank 101, ensuring the water quality of the water flowing into the 6th-level water tank 101, thereby further improving the reliability of the ecological effect simulation system 100.

[0040] Compared to related technologies, the present application has at least the following advantages: by configuring the water troughs 101 to include N levels, and vertically, the first height of the first water trough at the i-th level from the horizontal plane is less than the second height of the second water trough at the i+1-th level from the horizontal plane. In other words, there is a height difference between the water troughs 101 at adjacent levels, allowing water in the water troughs 101 at the higher level to automatically flow into the water troughs 101 at the lower level due to the height difference, thereby achieving simulation of the hierarchical structure and multi-scale characteristics of the river network and ensuring the fidelity of the river network simulation by the ecological effect simulation system 100. By configuring the number of second water troughs at the higher level to be greater than the number of first water troughs at the lower level, and configuring at least two second water troughs to be connected to the first water troughs via independent connecting pipes 102, simulation of the hierarchical structure and multi-scale characteristics of the river network is further achieved, thereby further improving the fidelity of the river network simulation by the ecological effect simulation system 100. In addition, the ecological effect simulation system 100 only requires a water tank 101, a connecting pipe 102 and a water supply device 103 to simulate the ecological effect of the river network, making the cost of the river network ecological effect simulation low.

[0041] Please refer to Figure 2 , Figure 2 This is a flowchart of the steps in one embodiment of the river network-based ecological effect simulation system of the present application. Depending on different needs, the order of the steps in this flowchart can be changed, and some steps can be omitted. The control method for the river network-based ecological effect simulation system of the present application is applied to the aforementioned ecological effect simulation system 100. The core of this embodiment lies in controlling the water supply device to supply water to the topmost water tank or the bottommost water tank. In this way, water supply control of the ecological effect simulation system can be achieved.

[0042] The specific process of this embodiment is as follows Figure 2 As shown, the following steps are included: S201: Control the water supply device to supply water to the uppermost water tank or the lowermost water tank.

[0043] S202: When controlling the water supply device to supply water to the uppermost water tank, respectively control the water flow rate and total water volume flowing into each uppermost water tank.

[0044] In some embodiments, the ecological effect simulation system is equipped with a first flow control valve at the water inlet of each top water tank, and the control device of the ecological effect simulation system controls the valve opening of each first flow control valve to control the water flow rate and total water volume of the water in the water supply device flowing into the top water tank.

[0045] It is worth noting that for the top water tanks located at the same level, the water flow rate and total water volume of the water in the water supply device flowing into different top water tanks can be the same or different, and can be set according to the actual situation of the river network to ensure the authenticity of the river network ecological effect simulation.

[0046] S203: Controlling the water flow rate of each second water tank when the water flows into the first water tank.

[0047] In some embodiments, the ecological effect simulation system sets a second flow control valve at the water outlet of each second water tank, and the control device controls the water flow rate of water in the second water tank when it flows into the first water tank by controlling the valve opening of each second flow control valve.

[0048] It is worth noting that for the second water tanks located at the same level, the water flow rates of water flowing into the corresponding first water tanks from different second water tanks can be the same or different, and can be set according to the actual situation of the river network to ensure the authenticity of the river network ecological effect simulation.

[0049] Compared to related technologies, the present application has at least the following advantages: by arranging N levels of water troughs, and in the vertical direction, the first height of the first water trough at the i-th level from the horizontal plane is less than the second height of the second water trough at the i+1-th level from the horizontal plane. In other words, the height difference between the water troughs at adjacent levels allows water in the water trough at the higher level to automatically flow into the water trough at the lower level due to the height difference, thereby simulating the hierarchical structure and multi-scale characteristics of the river network and ensuring the fidelity of the river network simulation by the ecological effect simulation system. By arranging the number of second water troughs at the higher level to be greater than the number of first water troughs at the lower level, and providing at least two second water troughs connected to the first water troughs via independent connecting pipes, the hierarchical structure and multi-scale characteristics of the river network are further simulated, thereby further improving the fidelity of the river network simulation by the ecological effect simulation system. In addition, the ecological effect simulation system only requires water troughs, connecting pipes, and water supply devices to simulate the ecological effects of the river network, making the cost of river network ecological effect simulation low.

Specific examples are used in this article to illustrate the principles and implementation methods of this application. The description of the above embodiments is only used to help understand the method of this application and its core idea; at the same time, for technical personnel in this field, based on the ideas of this application, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on this application.
