Description

Technical Field

[0001] This application belongs to the field of water conservancy equipment technology, specifically an ecological flow automatic adjustment and discharge device. Background Technology

[0002] Ecological flow automatic adjustment release is a modern water resource management technology that aims to regulate the release of water from reservoirs or dams through real-time monitoring and data analysis in order to maintain and improve the health of river ecosystems. Traditional dam releases are usually based on fixed schedules or water level requirements, while ecological flow automatic adjustment dynamically adjusts release strategies based on real-time hydrological and ecological data to simulate natural flow changes.

[0003] For example, the utility model patent with announcement number CN215669358U discloses an automatic flood discharge gate mechanism for water conservancy projects, belonging to the technical field of water conservancy equipment. This automatic flood discharge gate mechanism for water conservancy projects includes a dam body and a gate. A fixed rod is provided on the front right wall of the dam body, and a placement groove is opened on the front wall of the fixed rod. A threaded rod is placed in the placement groove. A protective box is provided on the front side of the fixed rod. Multiple fixing components are provided on the left and right inner walls of the protective box. A water level sensor is placed inside the protective box. By setting the threaded rod, the protective box containing the water level sensor can be moved up and down, making the water level sensor easy to maintain. Simultaneously, the flood discharge level can be adjusted according to different periods, making the device more practical. By setting the protective box, the water level sensor can be protected inside, preventing damage and greatly extending its service life. By setting the fixing components, the water level sensor can be fixed, facilitating its installation and disassembly.

[0004] However, in actual use, it was found that the device uses an adjustment mechanism to move the water level sensor closer to the water in the dam or reservoir in order to monitor the water level of the dam or reservoir in real time.

[0005] However, since there are a lot of debris inside dams or reservoirs, this debris can enter the fixed rod of the regulating mechanism. In this case, it will affect the normal regulation of the water level sensor. At the same time, the water level sensor of the device needs to be close to the water body, making it susceptible to the influence of water flow fluctuations. Therefore, an ecological flow automatic adjustment and release device is provided. Utility Model Content

[0006] The purpose of this application is to provide an ecological flow automatic adjustment and release device in order to solve the problems mentioned above.

[0007] The technical solution adopted in this application is as follows: An ecological flow automatic adjustment and release device includes a gate frame, a gate plate is provided inside the gate frame, an automatic adjustment mechanism connected to the gate plate is provided on the top surface of the gate frame, an installation housing is fixedly installed on the top surface of the gate frame, a plurality of rectangular holes are respectively opened on the front and rear sides of the installation housing, and an adjustment rod is slidably connected inside each of the plurality of rectangular holes, an installation plate is fixedly installed at one end of the adjustment rod, an ultrasonic water level gauge is fixedly installed on the top surface of the installation plate, a rack is fixedly installed on one side of the adjustment rod, a bearing is fixedly installed on the top surface of the installation housing, a rotating rod is fixedly installed through the middle of the bearing, a small gear is fixedly installed at the bottom end of the rotating rod, the small gear meshes with the rack, and a turntable is fixedly installed on the outer surface of the top end of the rotating rod.

[0008] In a preferred embodiment, the automatic adjustment mechanism includes a screw hoist, an adjusting screw, and a connecting seat. The screw hoist is fixedly installed on the top surface of the gate frame, and the adjusting screw is internally engaged with the screw hoist. The connecting seat is fixedly installed on the top surface of the gate plate, and a bearing seat is fixedly installed on the top surface of the connecting seat. The bottom end of the adjusting screw is fixedly installed in the middle of the bearing seat.

[0009] In a preferred embodiment, a control box is provided on the side of the gate frame, and a water flow meter is provided on the front side of the gate frame. The ultrasonic water level gauge, screw hoist, water flow meter and control elements installed inside the control box are electrically connected.

[0010] In a preferred embodiment, two limiting plates are symmetrically fixedly installed on the inner sidewall of the gate frame, and the left and right ends of the gate plate are respectively inserted into the interior of the limiting plates.

[0011] In a preferred embodiment, a plurality of reinforcing ribs are fixedly installed on the front side of the gate.

[0012] In a preferred embodiment, a baffle is fixedly installed on the top surface of the control box.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0014] 1. In this application, due to the adoption of the above-mentioned scheme, the user first rotates the turntable, which drives the rotating rod and the pinion to rotate. Since the pinion is meshed with the rack, when the pinion rotates, the two adjusting rods will move in opposite directions under the drive of the rack, which makes it easy to adjust the two ultrasonic water level gauges to the appropriate position to monitor the water level upstream and downstream of the gate. When it is necessary to disassemble or repair the ultrasonic water level gauges, simply rotate the pinion in the opposite direction to bring them closer to each other, so as to facilitate disassembly and repair and improve the convenience of operation.

[0015] By using a control box, water flow meter, ultrasonic level gauge, and screw gate hoist, dynamic balance management of ecological flow and downstream flow can be achieved during the non-flood season, thereby optimizing scheduling and maximizing power production. During the flood season, upstream rain gauges send real-time rainfall data to the control box, which then confirms the gate's operation mode to ensure timely response to instantaneous water level changes. This avoids overflow due to excessive water flow or low water levels due to insufficient flow. Through this intelligent linkage control method, the reservoir's water level and flow can be managed more effectively, ensuring the safe operation of the reservoir and the stability of power production, and realizing the automatic adjustment and release of ecological flow.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] refer to Figure 1 , Figure 2 and Figure 3An ecological flow automatic adjustment and release device includes a gate frame 1, a gate plate 2 is provided inside the gate frame 1, multiple reinforcing ribs 20 are fixedly installed on the front side of the gate plate 2, and an automatic adjustment mechanism 3 connected to the gate plate 2 is provided on the top surface of the gate frame 1. Multiple expansion bolts are provided on the side of the gate frame 1, which facilitates the installation and fixation of the gate frame 1 on the concrete dam body and the use of the gate plate 2 to achieve the water storage effect. The multiple reinforcing ribs 20 are provided to strengthen the gate plate 2 and improve its overall strength. The automatic adjustment mechanism 3 is provided to control the opening or closing of the gate plate 2.

[0022] refer to Figure 1 The dynamic adjustment mechanism 3 includes a screw hoist 14, an adjusting screw 15, and a connecting seat 16. The screw hoist 14 is fixedly installed on the top surface of the gate frame 1. The adjusting screw 15 is meshed and connected inside the screw hoist 14. The connecting seat 16 is fixedly installed on the top surface of the gate plate 2. A bearing seat is fixedly installed on the top surface of the connecting seat 16. The bottom end of the adjusting screw 15 is fixedly installed in the middle of the bearing seat. When the screw hoist 14 is started, its internal worm gear will drive the adjusting screw 15 to rotate, which facilitates the adjustment of the height of the gate plate 2 so that it can be opened or closed. The connecting seat 16 facilitates the connection between the adjusting screw 15 and the gate plate 2.

[0023] refer to Figure 1 , Figure 2 A mounting housing 4 is fixedly installed on the top surface of the gate frame 1. Multiple rectangular holes 5 are opened on the front and rear sides of the mounting housing 4, and an adjusting rod 6 is slidably connected inside each of the multiple rectangular holes 5. A total of four rectangular holes 5 are opened on the front and rear sides of the mounting housing 4. The four rectangular holes 5 are divided into two groups of two. An adjusting rod 6 is installed inside each of the two groups of rectangular holes 5, so that the two adjusting rods 6 can slide and adjust inside the two groups of rectangular holes 5.

[0024] refer to Figure 1 , Figure 2An installation plate 7 is fixedly installed at one end of the adjusting rod 6, and an ultrasonic water level gauge 8 is fixedly installed on the top surface of the installation plate 7. The installation plate 7 facilitates the installation and fixation of the ultrasonic water level gauge 8. The ultrasonic water level gauge 8 measures the water level by utilizing the propagation speed of ultrasonic waves in the air and the reflection characteristics of the water surface. Specifically, the ultrasonic water level gauge 8 emits ultrasonic pulses to the water surface and receives the ultrasonic signals reflected back from the water surface to calculate the water level. This measurement method has the advantages of being non-contact, wear-free, highly accurate, and having a fast response speed. The ultrasonic water level gauge 8 is fixed by fastening plates connected to the main body. In order to comprehensively monitor the water level, two ultrasonic water level gauges 8 are set up, one for monitoring the water level of the storage area and the other for monitoring the water level at the drainage point. This configuration makes it easier to carry out automatic adjustment and discharge operations in the future to achieve effective control and management of the water level.

[0025] There are various models of ultrasonic water level gauges, and the specific model can be selected according to actual debugging needs. This application provides an ultrasonic water level gauge model ZX1000.

[0026] refer to Figure 1 , Figure 2 A rack 9 is fixedly installed on one side of the adjusting rod 6, and a bearing 10 is fixedly installed on the top surface of the mounting housing 4. A rotating rod 11 is fixedly installed through the middle of the bearing 10, and a pinion 12 is fixedly installed at the bottom end of the rotating rod 11. The pinion 12 meshes with the rack 9, and a turntable 13 is fixedly installed on the outer surface of the top end of the rotating rod 11. When personnel need to repair or disassemble the ultrasonic water level gauge 8, they first rotate the turntable 13, which drives the rotating rod 11 to rotate. Since the pinion 12 meshes with the rack 9, the two adjusting rods 6 move in opposite directions under the drive of the rack 9. This facilitates the disassembly and repair of the ultrasonic water level gauge 8 near the gate frame 1, improving convenience.

[0027] refer to Figure 1 , Figure 2 A control box 17 is provided on the side of the gate frame 1, and a water flow meter 18 is provided on the front of the gate frame 1. The ultrasonic water level gauge 8, screw hoist 14, water flow meter 18 and control elements installed inside the control box 17 are electrically connected. Various control elements are installed inside the control box 17, including a PLC controller or microcontroller and its supporting components. The control box 17 is connected to the upstream rain gauge station through electronic signals to realize the transmission of real-time data.

[0028] During the non-flood season, the water flow meter 18 is installed in a place where the water flow is relatively gentle downstream of the gate 2. The water flow meter 18 is responsible for monitoring the water level downstream of the gate 2 and converting the monitored data into an electrical signal through the built-in sensor to feed back to the control box 17. When the water flow monitored by the water flow meter 18 is lower than the preset safety value, it will feed back the signal to the control box 17. The control box 17 controls the screw hoist 14 to operate based on this feedback information, driving the gate 2 to adjust its opening size to regulate the drainage volume. Conversely, if the flow is too large, the gate 2 is closed to reduce the flow, thereby realizing the dynamic balance management of ecological flow and downstream flow. In this way, the scheduling can be optimized and the power production can be maximized.

[0029] During the flood season, upstream rain gauges send real-time rainfall data to the control box 17. Based on this data, combined with past experience and historical data, the control box 17 estimates the changes in inflow water and adjusts the ecological flow control strategy accordingly. Based on these strategies, the control box 17 confirms the operation mode of the gate 2 to ensure timely response to instantaneous water level changes and avoid water overflow due to excessive flow or water level drop due to insufficient flow. Through this intelligent linkage control method, the reservoir's water level and flow can be managed more effectively, ensuring the safe operation of the reservoir and the stability of power production.

[0030] refer to Figure 1 A shield 21 is fixedly installed on the top surface of the control box 17; the shield 21 can protect the control box 17 and avoid direct sunlight as much as possible.

[0031] refer to Figure 1 , Figure 3 Two limiting plates 19 are symmetrically fixedly installed on the inner side wall of the gate frame 1. The left and right ends of the gate plate 2 are respectively inserted into the inside of the limiting plates 19. The two limiting plates 19 facilitate the limiting of the gate plate 2, making it more stable during adjustment.

[0032] The implementation principle of an embodiment of an ecological flow automatic adjustment and discharge device of this application is as follows: The user first installs the ultrasonic water level gauge 8 on the mounting plate 7, and then drives the rotating rod 11 and the pinion 12 to rotate by rotating the turntable 13. Since the pinion 12 is meshed with the rack 9, when the pinion 12 rotates, the two adjusting rods 6 will move in opposite directions under the drive of the rack 9, so as to make it easier to adjust the two ultrasonic water level gauges 8 to a suitable position to monitor the water level upstream and downstream of the gate 2. When it is necessary to disassemble or repair the ultrasonic water level gauge 8, simply rotate the pinion 12 in the opposite direction to bring them closer to each other, so as to make it easier to disassemble and repair, and improve the convenience of operation.

[0033] The device is simple in structure and easy to operate. By controlling the control box 17, water flow meter 18, ultrasonic water level gauge 8, and screw gate hoist 14, it can achieve dynamic balance management of ecological flow and downstream flow during the non-flood season, thereby optimizing scheduling and maximizing power production. During the flood season, the upstream rain gauge station will send real-time rainfall data to the control box 17. Based on this data, the control box 17 will estimate the changes in inflow and adjust the ecological flow control strategy accordingly. Based on these strategies, the control box 17 will confirm the operation mode of the gate 2 to ensure timely response to instantaneous water level changes, thereby avoiding overflow caused by excessive water flow or water level too low due to insufficient flow. Through this intelligent linkage control method, the water level and flow of the reservoir can be managed more effectively, ensuring the safe operation of the reservoir and the stability of power production, and realizing the automatic adjustment and release of ecological flow.
