Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects and ecological environment, and in particular to an ecological flow control device for a high mountain canyon type reservoir. Background Art

[0002] Ecological flow refers to the amount of water flowing within a watershed to maintain the ecological environment. Ecological flow regulation involves adjusting and maintaining the amount of water flowing through a water body based on the needs of high-altitude reservoirs and the survival requirements of aquatic life at higher altitudes. Setting and maintaining ecological flow aims to ensure biodiversity, habitat integrity, and the proper functioning of ecological processes within the ecosystem.

[0003] Ecological flow regulation is generally achieved by controlling the flow of water entering and leaving the reservoir. However, alpine canyon reservoirs have unique hydrological conditions (such as turbulent flow, large drop, and fast flow velocity), complex ecosystems, and complex geographical and ecological conditions. This makes ecological flow regulation in alpine canyon reservoirs difficult to implement. It is necessary to overcome the impact of turbulent water on the sluice gates caused by complex geographical and ecological conditions. It is also necessary to control the flow rate of reservoir discharge and increase the minimum flow rate of downstream rivers to meet the basic needs of aquatic ecosystems. Therefore, it is necessary to propose an ecological flow control device for alpine canyon reservoirs that can achieve intelligent regulation of ecological flow discharged from the reservoir. Utility Model Content

[0004] In order to solve the above problems, the utility model provides an ecological flow control device for a high mountain canyon reservoir. By setting a controller, the size of the discharge channel can be adjusted according to requirements such as flow rate and flow velocity, thereby realizing intelligent control of the ecological flow.

[0005] To achieve the above-mentioned objectives, the technical solution of the present invention is as follows: an ecological flow control device for a high mountain canyon reservoir, comprising a water inlet and a water outlet, wherein a water outlet gate is provided in the water outlet, and a first drive assembly is fixedly connected to the top of the water outlet gate for raising or lowering the water outlet gate according to downstream water flow requirements, and the first drive assembly is signal-connected to a controller;

[0006] The water outlet gate includes a gate frame, which is vertically slidably connected to the side wall of the water outlet. A through groove is provided on the gate frame, and a number of discharge plates are provided in the through groove. The tops of the discharge plates are slidably connected to the tops of the through grooves, and adjacent discharge plates fit together and slide horizontally. A number of discharge holes are provided on the discharge plates, and a number of hydraulic telescopic rods corresponding to the number of discharge plates are provided on both sides of the through groove. The output ends of the hydraulic telescopic rods are fixedly connected to one side of the corresponding discharge plate, and the input ends of the hydraulic telescopic rods are connected to the output end signals of the controller.

[0007] The technical principle of the above scheme is as follows: by lifting the sluice gate, the area of ​​water flowing through the water inlet is controlled, and the position of several discharge plates is adjusted by controlling several hydraulic telescopic rods through the controller. By adjusting the position of the discharge plates, the area of ​​the discharge channel is adjusted, thereby realizing intelligent and precise adjustment of the flow rate.

[0008] The above scheme has the following beneficial effects:

[0009] 1. When the downstream demand for water increases, the staff can use the controller to intelligently start the first drive component to raise the sluice gate, which can expand the area of ​​water flowing through the water inlet. At the same time, the controller can regulate the flow rate to achieve precise and intelligent adjustment.

[0010] 2. In this solution, when a smaller but more stable water flow is needed downstream of the reservoir, it can be adjusted by horizontally moving multiple spill plates within the gate frame. These spill plates change their relative positions during the sliding process, thereby opening or closing the spill holes to varying degrees, forming water flow channels of different sizes. The greater the relative movement distance between the spill plates, the smaller the area of ​​the water flow channel formed between them. This allows for precise control of the continuous discharge flow and improves the efficiency of flow regulation.

[0011] 3. Design several hydraulic telescopic rod signal connection controllers to intelligently adjust the discharge channel area to achieve more convenient and quick adjustment.

[0012] Furthermore, a first flow tester is fixedly connected to the drain hole and the bottom of the drain plate, and the output end of the first flow tester is signal-connected to the input end of the controller.

[0013] Beneficial effects: The first flow meter accurately monitors the flow of the discharged water. The operator flexibly adjusts the discharge flow according to the actual flow demand downstream of the reservoir to achieve scientific and reasonable control of the discharge flow. This design not only ensures the effective use of water resources, but also improves the adaptability and flexibility of the entire device.

[0014] Furthermore, a plurality of inclined buffer slopes are provided on the water-facing side of the water outlet. The buffer slopes are all slopes whose height away from the water outlet is smaller than that of the side close to the water outlet, and there are intervals between adjacent buffer slopes.

[0015] Beneficial effects: When water flows through the buffer slope area, given the complexity of the geographical environment and the diversity of geological conditions of high mountain canyon reservoirs, the water will exhibit a faster flow rate after passing through this area. In order to effectively address this problem, the design of the buffer slope cleverly utilizes its flow path and effectively slows down the speed of the water flow through reasonable slope settings. This design not only reduces the strong impact that turbulent water flow may cause on the downstream gate, thereby reducing the potential risk of damage, but also improves the durability and service life of the gate; in addition, a spacing is set between adjacent buffer slopes. The setting of this spacing not only helps the water flow to be more fully dispersed and buffered during the flow process, but also further extends the flow path of the water flow, thereby improving the efficiency of slowing down the water flow rate.

[0016] Furthermore, a first water inlet gate and a second water inlet gate are vertically slidably connected in sequence in the water inlet direction, a gap is provided between the first water inlet gate and the second water inlet gate for detecting the incoming water flow, and the tops of the first water inlet gate and the second water inlet gate are fixedly connected with a second drive assembly for controlling the flow according to the water level.

[0017] Beneficial Effects: The gap designed between the first and second intake gates serves as a pre-detection area for the reservoir's incoming water flow. This space allows staff to fully utilize its characteristics to make preliminary and effective judgments and assessments of the incoming water flow. This not only enhances the predictability and accuracy of reservoir inflow management but also provides a foundation for the development and implementation of subsequent flow control measures, thereby ensuring safe and efficient reservoir operations.

[0018] Furthermore, a water quality detector located in the gap between the first water inlet gate and the second water inlet gate is fixedly connected to the side wall of the water inlet, and the output end of the water quality detector is signal-connected to the input end of the controller.

[0019] Beneficial effect: When the reservoir needs to introduce new water, the operating controller is activated and the first water inlet gate is slowly lifted. This action allows the water to flow smoothly into the specially reserved gap area between the first and second water inlet gates. In this gap, the water flow will undergo a series of precise testing procedures, such as flow rate, water quality, and whether there is potential pollution. These test data are crucial for subsequent decision-making.

[0020] Furthermore, a second flow meter is fixedly connected to the bottom end of the first water inlet gate, and an output end of the second flow meter is signal-connected to an input end of the controller.

[0021] Beneficial effects: When the water flow successfully completes the pre-detection process and begins to officially enter the reservoir, it will flow through the second flow tester. This professional equipment, with its high sensitivity and precision, can instantly and accurately measure the actual flow of the water. Subsequently, these valuable flow data will be quickly transmitted to the controller. Through a series of efficient information processing mechanisms, the controller can feed back this flow information to the operator in real time. This design improves the efficiency of the operator in receiving real-time water inflow flow information, allowing the operator to grasp the dynamic situation of the water flow at the first time. With the support of real-time information, the operator can respond to various emergencies more calmly, flexibly adjust the water inflow strategy, ensure that the control of the water inflow flow is both accurate and efficient, improve the stability and safety of the reservoir operation, and provide guarantees for the rational use of water resources.

[0022] Furthermore, a dissolved oxygen detector is fixedly connected to a side of the second water inlet gate away from the first water inlet gate, and an output end of the dissolved oxygen detector is signal-connected to an input end of the controller.

[0023] Beneficial Effects: Alpine canyon reservoirs host unique and diverse aquatic communities, which often require specific environmental conditions, such as maintaining high levels of dissolved oxygen in the water. Dissolved oxygen detectors precisely monitor the dissolved oxygen content in reservoir waters. Based on the real-time data provided by these instruments, operators can accurately determine whether the current dissolved oxygen level in the reservoir meets the needs of biological survival. Once dissolved oxygen levels are found to be below the critical value required by organisms, operators can quickly take action, such as activating aeration equipment to oxygenate the water, or adjusting the water inlet schedule based on actual conditions, such as opening the water inlet gates in advance to introduce new water sources rich in dissolved oxygen. This addresses the special needs of aquatic organisms in alpine canyon areas and ensures they can thrive in the most suitable environment.

[0024] Furthermore, an aquatic vegetation buffer zone is provided on one side of the water inlet along the water flow.

[0025] Beneficial effects: Once water flows smoothly through the inlet and reaches the aquatic vegetation buffer zone, the lush and diverse branches and leaves of these aquatic plants, due to their unique characteristics, can slow the flow of water. Furthermore, their complex root systems can lock in the soil, effectively reducing the risk of soil erosion caused by water erosion and ensuring the reservoir can continue to perform its functions of water storage and ecological regulation in a long-term and stable manner.

[0026] Furthermore, the first drive assembly includes a first lifting rod, one end of the first lifting rod is fixedly connected to the gate frame, the first lifting rod away from the gate frame, one end extends through the top of the water outlet and is provided with a first electrically-controlled hydraulic cylinder outside the water outlet, the first electrically-controlled hydraulic cylinder displacement output end is upward and fixedly connected to the top of the first lifting rod, the signal input end of the first electrically-controlled hydraulic cylinder is signal-connected to the output end of the controller, the second drive assembly includes several second lifting rods and third lifting rods, one end of the second lifting rod is fixedly connected to the top of the first water inlet, one end of the third lifting rod is fixedly connected to the top of the second water inlet, the end of the second lifting rod away from the first water inlet extends through the water inlet to the outside of the water inlet and is fixedly connected to the second electrically-controlled hydraulic cylinder, the end of the third lifting rod away from the second water inlet extends through the water inlet to the outside of the water inlet and is fixedly connected to the third electrically-controlled hydraulic cylinder, the signal input ends of the several second electrically-controlled cylinders and the several third electrically-controlled cylinders are signal-connected to the signal output ends of the controller.

[0027] Beneficial Effects: Once the initial water flow test confirms it meets the reservoir's inflow standards and requirements, the second inlet gate is raised accordingly. The degree of opening of the first inlet gate becomes a key regulatory factor, directly determining the flow rate into the reservoir. By precisely controlling the opening of the first inlet gate, the system intelligently regulates the inflow, ensuring the reservoir receives the appropriate amount of water on demand while effectively avoiding potential problems caused by excessive or insufficient flow, thereby ensuring the stability and safety of the reservoir's operations.

[0028] Furthermore, an elastic buffer layer is fixedly connected to the water-facing side of the first water inlet gate and the spillway plate.

[0029] Beneficial Effects: Due to the complex and varied terrain of high mountain canyons, with significant ups and downs, significant height differences form. When water flows into the reservoir from this terrain, the enormous potential energy generated by the height difference gives it a strong momentum the moment it enters the reservoir. This powerful water flow, upon entering the reservoir, often directly impacts the closed area of ​​the outlet gate with great impact force, posing a potential threat to the gate and its surrounding structures. To effectively address this challenge, a spill plate equipped with a buffer layer was designed. When the potential energy generated by the height difference causes the water to violently rush towards the spill plate, the design of several buffer layers plays a key role. They not only effectively absorb and disperse the impact force of the water flow, reducing direct damage to the spill plate and the adjacent first water inlet gate, but also significantly extend the service life of these key components, thereby improving the stability and durability of the entire device.

[0040] The following is further described in detail through specific implementation methods:

[0041] Example 1:

[0042] As attached Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown: an ecological flow control device for a high mountain canyon reservoir, comprising a water inlet 1 and a water outlet 2, wherein a water outlet gate 3 is slidably connected to the water outlet 2 through a slider slot, and a first driving assembly for lifting or lowering the water outlet gate 3 according to the downstream water flow demand is fixedly connected to the top of the water outlet gate 3, and the bottom end of the water outlet gate 3 is in contact with the bottom surface of the reservoir, and the water outlet gate 3 comprises a gate frame 301, and the first driving assembly comprises a first lifting rod 11, one end of the first lifting rod 11 is fixedly connected to the gate frame 301, and the end of the first lifting rod 11 away from the gate frame 301 passes through the top of the water outlet 2 and extends to the outside of the water outlet 2. A first electrically controlled hydraulic cylinder 12 is provided, and the displacement output of the first electrically controlled hydraulic cylinder 12 The end is upward and fixedly connected to the top of the first lifting rod 11. The signal of the first electric-controlled hydraulic cylinder 12 is connected to the controller. The controller is preferably an S7-1200 Siemens PLC controller. The signal input end of the first electric-controlled hydraulic cylinder 12 is connected to the output end signal of the controller. When the water demand downstream increases, the staff can intelligently control the first electric-controlled hydraulic cylinder 12 to drive the extension through the controller. The output end of the first electric-controlled hydraulic cylinder 12 will drive the first lifting rod 11 to lift upward, and the first lifting rod 11 drives the gate frame 301 to lift, thereby increasing the flow area of ​​​​water passing through the water inlet 1, and controlling the flow by the controller can achieve precise and intelligent control.

[0043] The gate frame 301 is vertically slidably connected to the side wall of the water outlet 2 via a slider slot structure, so that the gate frame 301 can slide upward when the first drive assembly is started, thereby driving the upward sliding displacement of the water outlet gate 3.

[0044] A through slot 302 is provided on the gate frame 301, and a number of discharge pieces 303 are provided in the through slot 302. The tops of the discharge pieces 303 are slidably connected to the tops of the through slots 302, and adjacent discharge pieces 303 fit together and slide horizontally, so that the discharge pieces 303 can slide horizontally in the gate frame 301. A number of discharge holes 304 are provided on the discharge pieces 303. When the water flow demand downstream of the reservoir is small and continuous water delivery is required, the discharge pieces 303 can slide relative to each other in the gate frame 301 by sliding horizontally, and water flow channels of different sizes can be formed between the discharge holes 304 according to the different sliding degrees of the discharge pieces 303. The greater the relative displacement between the discharge pieces 303, the smaller the area of ​​the water flow channel formed between the discharge holes 304, thereby realizing flow control of continuous discharge. The effect is to improve the efficiency of flow control. A plurality of hydraulic telescopic rods 305 corresponding to the plurality of drain plates 303 are provided on both sides of the through slot 302. The hydraulic telescopic rods 305 are preferably Rexroth electrically controlled hydraulic cylinders. The output ends of the hydraulic telescopic rods 305 are welded to one side of the corresponding drain plate 303. The input ends of the hydraulic telescopic rods 305 are connected to the output end signals of the controller. The sliding of the plurality of drain plates 303 is driven by the corresponding hydraulic telescopic rods 305. The synchronous extension and contraction of the output ends of the plurality of hydraulic telescopic rods 305 correspond to the mutual approach and distance between the corresponding drain plates 303. In addition, through the signal connection between the controller and the plurality of hydraulic telescopic rods 305, the mutual displacement of the plurality of drain plates 303 is intelligently controlled, thereby realizing the intelligent control of the drain flow.

[0045] Example 2:

[0046] As attached Figure 4 As shown, the difference from Example 1 is that a first flow meter 4 is melt-welded inside the leakage hole 304 and at the bottom of the leakage plate 303. The flow meter is preferably a LD-LS300A model Liond portable flow meter. The output end of the first flow meter 4 is connected to the input end signal of the controller. The first flow meter 4 monitors the flow rate of the discharged water. This design enables the operator to control the ecological flow discharge flow of the downstream, realize the rational control of the discharge flow, and improve the adaptability of the device.

[0047] Example 3:

[0048] As attached Figure 1As shown, the difference from Example 2 is that a number of inclined buffer slopes 5 are provided on the water-facing side of the water outlet 2, and the buffer slopes 5 are all slopes with a height away from the water outlet 2 being less than the height close to the water outlet 2. When the water flows through the buffer slopes 5, due to the complex geological conditions of the geographical conditions of the high mountain canyon reservoir, the water will have a faster flow rate after passing through. The design of the buffer slopes 5 can slow down the flow rate of the water from the flow direction, thereby reducing the impact and damage of the turbulent water flow on the gate and improving durability. There is a distance between adjacent buffer slopes 5. By setting a certain distance, the flow path of the water can be extended and the efficiency of slowing down the flow rate of the water can be improved.

[0049] Example 4:

[0050] As attached Figure 2 As shown, the difference from Example 3 is that the first water inlet gate 6 and the second water inlet gate 7 are vertically slidably connected in sequence in the water inlet 1 along the water flow direction, and a gap is provided between the first water inlet gate 6 and the second water inlet gate 7 for detecting the inlet water flow. The gap provided between the first water inlet gate 6 and the second water inlet gate 7 provides a pre-detection space for the inlet water flow of the reservoir, which is conducive to judging the inlet flow rate. The top of the first water inlet gate 6 is fixedly connected to a second drive assembly for flow control according to the water level, and the second drive assembly includes a plurality of second lifting rods 13 and a third lifting rod 16. One end of the second lifting rod 13 is fixedly connected to the top of the first water inlet gate 6, and one end of the third lifting rod 16 is fixedly connected to the top of the second water inlet gate 7. The second lifting rod 13 is away from the first water inlet gate 6. One end of each extends through the water inlet 1 to the outside of the water inlet 1 and is fixedly connected to the second electrically-controlled hydraulic cylinder 14. One end of the third lifting rod 16 away from the second water inlet gate 7 extends through the water inlet 1 to the outside of the water inlet 1 and is fixedly connected to the third electrically-controlled hydraulic cylinder 17 through a coupling. The signal input ends of the plurality of second electrically-controlled hydraulic cylinders 14 and the plurality of third electrically-controlled hydraulic cylinders 17 are all connected to the signal output ends of the controller. When the reservoir needs to inlet water, the first water inlet gate 6 is first lifted to allow the water flow to enter the gap between the first water inlet gate 6 and the second water inlet gate 7. The water flow is detected and processed according to the detection. When it is confirmed that the water inlet requirements are met, the second water inlet gate 7 is lifted again. The size of the water inlet flow is controlled by the lifting amount of the first water inlet gate 6, thereby realizing intelligent regulation of the water inlet flow.

[0051] A second flow meter 15 is fixedly connected to the bottom end of the first water inlet gate 6, and the output end of the second flow meter 15 is signal-connected to the input end of the controller. When the water flow is detected and starts to flow in, the water flows through the second flow meter 15. The second flow meter 15 will detect the flow rate of the water flow and transmit the flow information to the operator through the controller, thereby improving the efficiency of the operator in receiving real-time water inlet flow information and facilitating the operator's control of the water inlet flow.

[0052] Example 5:

[0053] As attached Figure 2 As shown, the difference from Example 4 is that the side wall of the water inlet 1 is fixedly connected to a water quality detector 8 located in the gap between the first water inlet 6 and the second water inlet 7. The model of the water quality detector 8 is preferably LH-C660 Luheng Biotechnology Portable COD Ammonia Nitrogen and Total Phosphorus Detector. When the water flows into the gap between the first water inlet 6 and the second water inlet 7, the water quality detector 8 will perform water quality detection on the water in the gap. At the same time, the operator performs water sampling detection to realize the detection of the water entering the reservoir, reducing the risk of pollution to the ecological environment in the reservoir due to problems with the inlet water quality. The output end of the water quality detector 8 is signal-connected to the input end of the controller.

[0054] Example 6:

[0055] As attached Figure 2 As shown, the difference from Example 5 is that a dissolved oxygen detector 9 is fixedly connected to the side of the second water inlet 7 away from the first water inlet 6. The dissolved oxygen detector 9 is preferably an AR8406 type Xima dissolved oxygen meter. The output end of the dissolved oxygen detector 9 is signal-connected to the input end of the controller. Since the aquatic species in the high mountain canyon reservoir are special, a more unique water environment is required, such as environmental conditions such as high dissolved oxygen in the water body. During the period when the water inlet 1 is normally closed, the dissolved oxygen in the reservoir is detected by the dissolved oxygen detector 9 to determine whether the water in the reservoir needs to be oxygenated or the time of water inlet is advanced to meet the special needs of organisms in the high mountain canyon area.

[0056] Example 7:

[0057] As attached Figure 1 As shown, the difference from Example 6 is that an aquatic vegetation buffer zone 10 is provided on the side of the water inlet 1 along the flow direction of the water. When the water flows into the reservoir through the water inlet 1, it will pass through the aquatic vegetation buffer zone 10. The plant characteristics of the aquatic vegetation buffer zone 10 will, on the one hand, achieve the effect of slowing down the water body, and on the other hand, the density of the roots of the aquatic plants will reduce the risk of soil erosion when the water flows into the reservoir.

[0058] Example 8:

[0059] As attached Figure 1 、 Figure 2 and Figure 3As shown, the difference from Example 7 is that the first water inlet gate 6 and the spillway plate 303 are fixedly connected to the water-facing side with an elastic buffer layer. Due to the rugged terrain of the mountain canyon, the large height difference will cause the water flow to have a large potential energy after entering the reservoir, and impact the closure of the water outlet gate 3 of the outlet 2. When the water flows into the reservoir and rushes towards the spillway plate 303 due to the potential energy generated by the height difference, the buffer layer on the surface of the spillway plate 303 will reduce the impact force of the water flow, thereby improving the durability of the spillway plate 303 and the first water inlet gate 6 and improving the safety of the device.

[0060] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
