Description

Technical Field

[0001] This application belongs to the field of hydraulic gate technology, specifically an adaptive regulating hydraulic gate control device. Background Technology

[0002] Hydraulic gates are water-blocking or water-discharging structures built in water conservancy projects such as rivers, canals, and reservoirs to control water levels, regulate flow, prevent floods, drain water, or supply irrigation water. They typically consist of gate panels, gate piers, and opening and closing devices. By changing the opening and closing degree of the gate panels, the flow of water can be regulated. In reality, medium and large-sized hydraulic gates are mostly equipped with electric or hydraulic hoists. Operators send commands from the control room via buttons, consoles, or remote control systems to drive motors or hydraulic devices to move the gate panels. Some modern gates also incorporate monitoring equipment such as water level sensors and flow sensors to achieve semi-automatic or fully automatic control that automatically adjusts the gate panel opening degree based on real-time hydrological data, in order to adapt to different water conservancy scheduling needs.

[0003] For example, the utility model patent with announcement number CN220035342U discloses a small-scale automatic control device for water conservancy gates, including a water channel, a hydraulically controlled gate lifting device, a photovoltaic power generation and energy storage device, an operation panel, a hydraulic oil tank, and a control system. The hydraulically controlled gate lifting device is installed on the top of the water channel. The automatic gate control device of this utility model can automatically lift and lower to drain water through hydraulic control in conjunction with a water level detection sensor. At the same time, it can automatically adjust according to the different widths of the water channel by means of adjustable sealing movable supports on both sides, further enhancing the sealing effect and applicability of the gate.

[0004] However, in actual use, it was discovered that the device achieves adaptive adjustment of the gate through the cooperation of the control device and the water level detection sensor. However, the water level detection sensor of this device is installed on the inner wall of the canal, which is easily blocked or attached by foreign objects such as weeds and silt in the water flow, resulting in distorted detection data. At the same time, the sensor is installed inside the canal, making it inconvenient for personnel to inspect and maintain it. The operation is inconvenient and poses safety hazards, increasing the difficulty and cost of later maintenance. Therefore, an adaptive regulating hydraulic gate control device is provided.

[0016] 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.

[0017] refer to Figures 1-5The aforementioned adaptive regulating hydraulic gate control device includes a hydraulic gate frame 1, a gate 2 is installed inside the hydraulic gate frame 1, and a buffer baffle 15 is fixedly installed on the front side of the gate 2 by bolts. An regulating control mechanism 3 connected to the gate 2 is installed inside the hydraulic gate frame 1. The hydraulic gate frame 1 is installed in the river channel, and through cooperation with the gate 2, it can effectively control the water level and regulate the flow. The buffer baffle 15 can effectively alleviate the direct impact of the water flow on the gate 2 and reduce the wear of the gate 2 caused by the water flow impact force.

[0018] refer to Figures 1-5 A mounting housing 4 is fixedly installed on the right side of the hydraulic gate frame 1. Two adjusting rods 5 are movably inserted through one side of the mounting housing 4, and connecting support plates 6 are fixedly installed at the ends of the two adjusting rods 5 that are far apart from each other. A limiting connecting rod 14 is movably inserted through one side of the mounting housing 4. One end of the limiting connecting rod 14 is fixed to one side of the connecting support plate 6. A sensor bracket 7 is fixedly installed on one side of the connecting support plate 6, and an ultrasonic water level sensor 8 is fixedly installed on the top surface of the sensor bracket 7. The limiting connecting rod 14 can limit and guide the movement of the adjusting rods 5, ensuring the stability of the adjusting rods 5 when they move and preventing them from deviating. This ensures that the position adjustment of the ultrasonic water level sensor 8 is accurate. The ultrasonic water level sensor 8 can monitor water level changes in real time and provide accurate water level data for the adaptive adjustment of the gate. The ultrasonic water level sensor 8 is a common device in reality. This application only uses it and does not improve its structure. It will not be described in detail here.

[0019] refer to Figures 1-5 The regulating control mechanism 3 includes an internal threaded seat 301, an adjusting screw 302, a bearing seat 303, and a drive motor 304. The internal threaded seat 301 is fixedly installed on the top surface of the gate 2, and the adjusting screw 302 is threadedly connected to the middle of the internal threaded seat 301. The bearing seat 303 is fixedly installed on the top surface of the gate frame 1, and the top end of the adjusting screw 302 is fixedly installed in the middle of the bearing seat 303. The drive motor 304 is fixedly installed on the top surface of the gate frame 1, and the drive end of the drive motor 304 is fixed to the top end of the adjusting screw 302. A control box 16 is fixedly installed on the front side of the gate frame 1. The ultrasonic water level sensor 8 and the drive motor 304 are electrically connected to the control components inside the control box 16. The bearing seat 303 provides stable support for the adjusting screw 302, ensuring its smooth rotation. The drive motor 304 drives the adjusting screw 302 to rotate, which in turn moves the gate 2 up and down via the internal threaded seat 301, thus achieving automatic gate adjustment. The control components within the control box 16 include a microprocessor (such as a microcontroller or PLC), a signal processing module, relays or contactors, and a power supply module. The microprocessor handles data processing and logical judgments. The signal processing module filters, amplifies, and converts the signal transmitted from the ultrasonic level sensor 8. The relays or contactors control the start, stop, and direction of the drive motor 304. The power supply module provides stable power to all components. The ultrasonic level sensor 8 transmits the real-time monitored water level signal to the control box 16, where it is processed by the internal signal processing unit. After processing by the processing module, the data is sent to the microprocessor. The microprocessor compares and analyzes the measured water level with the preset threshold. When adjustment is required, the drive motor 304 is started via a relay or contactor. The drive motor 304 drives the adjusting screw 302 to rotate, causing the internal thread seat 301 to move the gate 2 up and down to change the opening. The change in the gate opening causes the water level to change accordingly. The ultrasonic water level sensor 8 continuously monitors the new water level and feeds it back to the control box 16, forming a complete closed-loop control. This allows the gate to automatically complete adaptive adjustment according to the water level change, improving the accuracy and automation of the adjustment. Moreover, the ultrasonic sensing technology, microprocessor control technology, and motor drive technology involved in the above structure are all mature existing technologies.

[0020] refer to Figures 1-5 As described above, each of the two adjusting rods 5 has a groove 9 on its side facing each other. A rack 10 is fixedly installed inside the groove 9. A main rotating shaft 11 is rotatably connected to the inside of the mounting housing 4 through a bearing. A gear 12 is fixedly installed on the outer surface of the main rotating shaft 11 near the middle. The gear 12 meshes with the rack 10. One end of the main rotating shaft 11 extends to the outside of the mounting housing 4. A handwheel 17 is fixedly installed on the outer surface of the end of the main rotating shaft 11 extending to the outside of the mounting housing 4. A fixing mechanism 13 is provided at the end of the main rotating shaft 11 extending to the outside of the mounting housing 4. By rotating the handwheel 17, the main rotating shaft 11 can be driven to rotate, so that the gear 12 meshes with the rack 10 to achieve synchronous reverse movement of the two adjusting rods 5, thereby adjusting the position of the ultrasonic water level sensor 8 to adapt to different monitoring needs. The handwheel 17 facilitates manual adjustment and improves the flexibility of the device.

[0021] refer to Figures 1-5The fixing mechanism 13 includes a disc 1301, fixing bolts 1302, and circular grooves 1303. The disc 1301 is fixedly installed on the outer surface of one end of the main rotating shaft 11 that extends to the outside of the mounting housing 4. The fixing bolts 1302 are threadedly connected to one side of the disc 1301. Multiple circular grooves 1303 corresponding to the fixing bolts 1302 are opened on one side of the mounting housing 4. After the personnel rotate the main rotating shaft 11 to adjust the position of the ultrasonic water level sensor 8, the personnel can screw the fixing bolts 1302 into the corresponding circular grooves 1303 to fix the main rotating shaft 11, preventing it from rotating due to vibration or other reasons during operation, ensuring the stability of the position of the ultrasonic water level sensor 8, and ensuring the accuracy of the monitoring data.

[0022] The implementation principle of the adaptive regulating hydraulic gate control device of this application is as follows: The user first installs the ultrasonic water level sensor 8 on the sensor bracket 7, and then rotates the handwheel 17 according to the actual monitoring needs, which drives the main rotating shaft 11 to rotate. Through the meshing transmission of the gear 12 and the rack 10, the two regulating rods 5 move synchronously in opposite directions, thereby adjusting the position of the ultrasonic water level sensor 8. After the position is determined, the main rotating shaft 11 is fixed by the fixing mechanism 13 to ensure that the ultrasonic water level sensor 8 works stably. The ultrasonic water level sensor 8 monitors the water level information in real time and transmits the signal to the control box 16. The control element in the control box 16 analyzes and processes the water level data. When the water level reaches the preset adjustment value, the control drive motor 304 is started. The drive motor 304 drives the adjusting screw 302 to rotate, which drives the gate 2 to move up and down through the internal thread seat 301, so as to realize the opening or closing of the gate to regulate the water flow. The device uses two ultrasonic water level sensors 8 located upstream and downstream of the gate to monitor different water levels in real time. When the upstream water level is high and the downstream water level is low, the water level can be adaptively adjusted by adjusting the control mechanism 3, the ultrasonic water level sensors 8, and the control components inside the control box 16. At the same time, by adjusting the support rod 5, the two ultrasonic water level sensors 8 can be moved to a calmer area in front of the gate to monitor the water level, thereby improving the accuracy of monitoring. The movement of the ultrasonic water level sensors 8 also facilitates subsequent installation, testing, and maintenance, effectively improving the management efficiency and safety of the water conservancy project.
