Description

Technical Field

[0001] This utility model relates to the field of hydraulic steel dam technology, and in particular to a device for precise control of the height of a hydraulic steel dam. Background Technology

[0002] Hydraulic steel dams are water conservancy devices used for urban flood control, environmental beautification, irrigation, and power generation. They function as "movable" water-retaining structures, regulating upstream water levels. Traditional hydraulic steel dams cannot control their height and can only operate at their designed height. This lack of flexibility prevents them from adjusting upstream water levels during periods of high water (lowering the dam) and low water (raising the dam). In short, adjusting the operating height of the hydraulic steel dam cannot regulate the upstream water level. Utility Model Content

[0003] To overcome the above deficiencies, this utility model provides a device for precise control of the height of a hydraulic steel dam, aiming to improve the problem in the prior art that the upstream water level cannot be adjusted by adjusting the operating height of the hydraulic steel dam.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a device for precise control of the height of a hydraulic steel dam, comprising a base plate and a mounting frame plate, wherein a hydraulic control pump station and a control system are sequentially installed on the top of the base plate from left to right, a hydraulic steel dam panel and a hydraulic cylinder are installed on the top of the mounting frame plate, the output end of the hydraulic cylinder is installed on the back of the hydraulic steel dam panel, an angle sensor is also installed on the back of the hydraulic steel dam panel, and a lubrication assembly is installed on the top of the mounting frame plate;

[0005] The lubrication assembly includes a rotating shaft and a cylinder. The rotating shaft is installed on the outer wall of the hydraulic steel dam panel and rotates with the hydraulic steel dam panel. An eccentric wheel is fixedly connected to the side of the rotating shaft away from the hydraulic steel dam panel. The cylinder is installed on the top of the mounting plate via a bracket. A piston is slidably connected inside the cylinder. A connecting rod is fixedly connected to the top of the piston. A pressing plate is fixedly connected to the top of the connecting rod. A spring is sleeved on the outer wall of the connecting rod. An electromagnetic check valve and a non-return valve are respectively installed at the bottom of the cylinder.

[0006] As a further description of the above technical solution:

[0007] An oil pipe trench is provided between the mounting plate and the base plate, an oil cylinder pipeline is connected between the hydraulic control pump station and the hydraulic cylinder, and a signal line is connected between the control system and the tilt sensor.

[0008] As a further description of the above technical solution:

[0009] The cylinder pipeline and the outer wall of the signal line are both installed inside the oil pipe trench, and a valve is provided on the outer wall of the cylinder pipeline.

[0010] As a further description of the above technical solution:

[0011] A lubricating oil tank is installed on the top of the mounting plate, and an oil inlet is provided on the top of the lubricating oil tank. An oil outlet pipe is installed at the bottom of both the check valve and the oil outlet pipe.

[0012] As a further description of the above technical solution:

[0013] The end of the oil outlet pipe away from the check valve is located at the rotation point of the hydraulic steel dam panel, and the end of the oil outlet pipe away from the electromagnetic check valve is located inside the lubricating oil tank.

[0014] As a further description of the above technical solution:

[0015] One end of the spring is installed on the top of the cylinder, and the other end of the spring is installed on the bottom of the extrusion plate.

[0016] As a further description of the above technical solution:

[0017] The eccentric wheel protrusion is fitted together with the top of the extrusion plate.

[0018] As a further description of the above technical solution:

[0019] The control system has multiple control buttons, a control panel, and a switch on its surface.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the height of the hydraulic steel dam panel can be precisely adjusted through the coordinated operation of the hydraulic control pump station, the control system, and the tilt sensor. Based on the real-time tilt angle information of the hydraulic steel dam panel fed back by the tilt sensor, the control system quickly issues precise commands to the hydraulic control pump station, effectively responding to changes in the position of the hydraulic steel dam panel caused by various factors. This ensures that the dam body can stably maintain a preset height position under different working conditions, thereby precisely controlling key parameters such as the dam's flow rate and water level, greatly improving the accuracy and reliability of the water conservancy project operation.

[0022] 2. In this invention, the rotational motion of the hydraulic steel dam panel is cleverly converted into a power source for the lubrication components through the cooperation of the eccentric wheel, extrusion plate, and springs, eliminating the need for additional power input and reducing energy consumption and costs. During the rotation of the eccentric wheel, the piston reciprocates within the cylinder via a connecting rod. Combined with the precise control of the lubricating oil flow direction by the electromagnetic check valve and non-return valve, directional and intermittent delivery of lubricating oil from the lubricating oil tank to the rotating part of the hydraulic steel dam panel is achieved. This effectively reduces frictional resistance during the rotation of the hydraulic steel dam panel, reduces wear, and extends the service life of the equipment's mechanical components.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 2-3 This utility model provides an embodiment of a device for precise height control of a hydraulic steel dam, comprising a base plate 1 and a mounting frame 6. A hydraulic control pump station 3 and a control system 2 are sequentially mounted on the top of the base plate 1 from left to right. The hydraulic control pump station 3 serves as the power source for the entire hydraulic system, providing stable and adjustable hydraulic power to the hydraulic cylinder 8, thereby driving the lifting and lowering of the hydraulic steel dam panel 7. The control system 2 is responsible for precise control and monitoring of the entire device's operation. It receives signals from various sensors, such as the tilt sensor 11, and issues commands to the hydraulic control pump station 3 according to preset programs and parameters to achieve precise height control of the hydraulic steel dam, ensuring stable operation and reaching the expected height position under different working conditions. The top of the mounting plate 6 is equipped with a hydraulic steel dam panel 7 and a hydraulic cylinder 8. The output end of the hydraulic cylinder 8 is installed on the back of the hydraulic steel dam panel 7. Under the action of hydraulic power, the hydraulic cylinder 8 performs telescopic movement, and its output end is tightly connected to the hydraulic steel dam panel 7. This allows the telescopic movement of the cylinder to be directly converted into the lifting and lowering action of the hydraulic steel dam panel 7. By precisely controlling the stroke and telescopic speed of the hydraulic cylinder 8, the height of the hydraulic steel dam panel 7 can be accurately adjusted, thereby controlling important parameters such as the water flow and water level of the dam body, and meeting various needs in water conservancy projects. A tilt sensor 11 is also installed on the back of the hydraulic steel dam panel 7. The tilt sensor 11 monitors the tilt angle of the hydraulic steel dam panel 7 in real time and transmits the angle data to the control system 2. During the lifting and lowering of the hydraulic steel dam, various factors such as water flow impact and foundation settlement may cause the hydraulic steel dam panel 7 to tilt. The tilt sensor 11 can detect this tilt change in time, and the control system 2 can make rapid adjustments based on the received signal to ensure that the hydraulic steel dam panel 7 is always kept within the angle range required by the design, thereby improving the safety and stability of the hydraulic steel dam operation and avoiding safety accidents and structural damage caused by excessive tilting. The top of the mounting plate 6 is equipped with a lubrication component. The lubrication component is mainly set to reduce the frictional resistance of the hydraulic steel dam panel 7 during rotation, extend the service life of the equipment, and ensure its smooth and reliable operation.

[0033] Reference Figure 5 and Figure 6The lubrication assembly includes a rotating shaft 12 and a cylinder 14. The rotating shaft 12 is installed on the outer wall of the hydraulic steel dam panel 7 and rotates with the hydraulic steel dam panel 7. An eccentric wheel 13 is fixedly connected to the side of the rotating shaft 12 away from the hydraulic steel dam panel 7. Through the rotation of the eccentric wheel 13, the rotational motion of the hydraulic steel dam panel 7 is converted into mechanical motion that can drive the lubrication assembly to work, realizing the organic combination of equipment motion and lubrication function, and improving the automation level and operating efficiency of the device. The cylinder 14 is mounted on top of the mounting plate 6 via a bracket. A piston 15 is slidably connected inside the cylinder 14. A connecting rod 16 is fixedly connected to the top of the piston 15, and a pressing plate 17 is fixedly connected to the top of the connecting rod 16. A spring 18 is sleeved on the outer wall of the connecting rod 16. An electromagnetic check valve 19 and a check valve 20 are respectively installed at the bottom of the cylinder 14. During the rotation of the eccentric wheel 13, when the protruding part of the eccentric wheel 13 contacts the top of the pressing plate 17, it applies downward pressure to the pressing plate 17. The pressing plate 17 transmits this pressure to the piston 15 via the connecting rod 16, causing the piston 15 to slide downwards inside the cylinder 14. At this time, the spring 18 is compressed, increasing the pressure inside the cylinder 14. During this process, the electromagnetic check valve 19 and the check valve 20 control the flow direction of the lubricating oil based on their unidirectional conduction characteristics. The electromagnetic check valve 19 can be opened or closed under a specific control signal, while the check valve 20 always prevents the reverse flow of lubricating oil, thereby realizing the directional delivery of lubricating oil from the lubricating oil tank 4 to the rotating part of the hydraulic steel dam panel 7, providing reliable lubrication for the rotating parts, reducing friction and wear, reducing equipment maintenance costs, and improving the reliability and durability of the equipment.

[0034] Reference Figures 1-3 An oil pipe trench 9 is provided between the mounting plate 6 and the base plate 1. The oil pipe trench 9 provides a good laying channel for the cylinder pipeline 5 and signal line 10, allowing them to be connected to various components in an orderly manner. The oil pipe trench 9 protects the cylinder pipeline 5 and signal line 10 from external environmental factors such as sunlight, rain, and mechanical impact, extending their service life. It also makes the overall appearance of the device neater and more aesthetically pleasing, facilitating equipment installation, maintenance, and management. The hydraulic control pump station 3 and the hydraulic cylinder 8 are connected by the cylinder pipeline 5. The cylinder pipeline 5 serves as a transmission channel for hydraulic oil, ensuring that the hydraulic power output from the hydraulic control pump station 3 is accurately transmitted to the hydraulic cylinder 8, guaranteeing the normal operation of the hydraulic cylinder 8. The control system 2 and the tilt sensor 11 are connected by a signal line 10. The signal line 10 acts as a bridge for information exchange between the control system 2 and the tilt sensor 11, enabling timely and accurate transmission of the angle data collected by the tilt sensor 11. This allows the control system 2 to make rapid and effective control decisions based on this data.

[0035] Both the hydraulic cylinder pipeline 5 and the signal line 10 are installed inside the oil pipe trench 9. This installation enhances their protection and reduces the risk of pipeline rupture or signal interruption due to unforeseen circumstances. A valve is installed on the outer wall of the hydraulic cylinder pipeline 5, allowing for convenient control of the hydraulic oil flow and direction. During equipment commissioning, maintenance, and emergencies, the valve can be operated to achieve individual control of the hydraulic cylinder 8 or partial isolation of the entire hydraulic system, improving operational flexibility and safety, and facilitating equipment maintenance and troubleshooting.

[0036] Reference Figures 1-3 A lubricating oil tank 4 is installed on the top of the mounting plate 6. The lubricating oil tank 4 has an oil inlet on its top. Serving as a storage container for lubricating oil, the tank allows for easy replenishment through the top inlet, ensuring sufficient lubricating oil supply to the lubrication components. Both the check valve 20 and the solenoid check valve 21 have oil outlet pipes 21 installed at their bottoms. During lubrication, lubricating oil flows from the lubricating oil tank 4 through the oil outlet pipes 21, check valves 20, and other components to the rotating parts of the hydraulic steel dam panel 7, providing continuous lubrication to these parts. This ensures smooth equipment operation, reduces heat and energy loss due to friction, and improves equipment efficiency and service life.

[0037] Reference Figures 1-3 The end of the oil outlet pipe 21 away from the check valve 20 is located at the rotating part of the hydraulic steel dam panel 7, and the end of the oil outlet pipe 21 away from the solenoid check valve 19 is located inside the lubricating oil tank 4, so that the lubricating oil can be accurately delivered to the rotating part of the hydraulic steel dam panel 7 that needs lubrication, ensuring the effectiveness of the lubrication effect.

[0038] Reference Figure 6 One end of the spring 18 is mounted on the top of the cylinder 14, and the other end is mounted on the bottom of the extrusion plate 17. When the protruding part of the eccentric wheel 13 applies downward pressure to the extrusion plate 17, the spring 18 is compressed, storing elastic potential energy. Once the protruding part of the eccentric wheel 13 leaves the extrusion plate 17, the spring 18 releases its elastic potential energy, pushing the extrusion plate 17 upward to reset, thereby driving the connecting rod 16 and the piston 15 back to their initial position or near their initial position, preparing for the next lubrication operation.

[0039] Reference Figure 5 and Figure 6 The eccentric wheel 13 protrudes and the top of the extrusion plate 17 fit together, ensuring that the eccentric wheel 13 can stably apply pressure to the extrusion plate 17 during rotation, so that the extrusion plate 17 can move up and down according to the rotation law of the eccentric wheel 13, thereby driving the piston 15 to slide back and forth in the cylinder 14, realizing the intermittent pumping of lubricating oil.

[0040] Reference Figures 1-3The control system 2 is equipped with multiple control buttons, a control panel, and a switch. The control buttons allow operators to easily control various functions of the hydraulic steel dam individually, such as start, stop, raising, and lowering. The control panel clearly displays the current status information of the hydraulic steel dam, such as height, tilt angle, and hydraulic system pressure, enabling operators to monitor the equipment's operation in real time. The switch controls the power supply to the entire control system 2. When the equipment is not in use or requires maintenance, the power can be cut off to ensure the safety of the equipment and personnel. These operating components enhance the ease of operation and human-machine interaction, facilitating precise control and management of the hydraulic steel dam.

[0041] Working principle: First, the hydraulic control pump station 3 inputs hydraulic oil into the hydraulic cylinder 8. The hydraulic cylinder 8 extends or retracts under the action of oil pressure. The hydraulic steel dam panel 7 rises or falls under the action of the hydraulic cylinder 8. The tilt sensor 11 installed on the hydraulic steel dam panel 7 transmits data to the control system 2 in real time as the angle of the hydraulic steel dam panel 7 changes.

[0042] After the control system 2 collects the real-time angle value of the hydraulic steel dam panel 7, it calculates the actual height value of the panel and compares it with the preset value of the control system 2. When the actual height value of the hydraulic steel dam panel 7 is lower than the preset value of the control system 2, the hydraulic control pump station 3 is started, the hydraulic cylinder 8 extends under the action of hydraulic oil, the hydraulic steel dam panel 7 begins to rise, and the angle value of the tilt sensor 11 gradually increases as the panel rises. The real-time angle value is converted into a height value by the control system 2. When the actual height value reaches the preset value of the control system 2, the hydraulic cylinder 8 stops working, and the hydraulic steel dam panel 7 remains at the current height. When the actual height of the hydraulic steel dam panel 7 is higher than the preset value of the control system 2, the hydraulic control pump station 3 starts, the hydraulic cylinder 8 retracts under the action of hydraulic oil, and the hydraulic steel dam panel 7 begins to descend. The angle value of the tilt sensor 11 gradually decreases as the panel descends, and the real-time angle value is converted into a height value by the control system 2. When the actual height value reaches the preset value of the control system 2, the hydraulic cylinder 8 stops working, and the hydraulic steel dam panel 7 remains at the current height. During the process of adjusting the tilt angle, the rotation of the hydraulic steel dam panel 7 drives the rotating shaft 12 to rotate. When the rotating shaft 12 rotates, it drives the eccentric wheel 13 to rotate, causing the protruding part of the eccentric wheel 13 to squeeze the extrusion plate 17, causing the extrusion plate 17 to slide up and down. This further drives the connecting rod 16 to slide up and down while squeezing the spring 18, causing the spring 18 to generate potential energy. When the connecting rod 16 slides, it changes the air pressure inside the cylinder 14, causing the lubricating oil inside the lubricating oil tank 4 to be transported to the rotating part of the hydraulic steel dam panel 7 through the oil outlet pipe for lubrication. Intermittent lubrication or stopping lubrication is achieved through the electromagnetic one-way valve 19.
