Description

Technical Field

[0001] This application relates to the technical field of gate opening calibration equipment, and in particular to a hydraulic gate opening calibration device. Background Technology

[0002] Hydraulic gates are structures built on rivers and canals to control flow and regulate water levels. Closing the gates can block floods, tides, or raise upstream water levels to meet the needs of irrigation, power generation, navigation, aquaculture, environmental protection, industrial and domestic water use; opening the gates can release floodwaters, floodwaters, wastewater, or polluted water, and can also supply water to downstream rivers or canals.

[0003] Gate opening refers to the degree to which a gate is opened, and it is an important indicator for measuring the size of the gate opening. Gates are usually made of metal. In existing metal hydraulic gates, the sliding connection between the gate and the gate body is constantly exposed to water, making them susceptible to blockage by silt and debris in the water flow, as well as metal corrosion. This leads to a significant increase in sliding resistance during the opening and closing process, making the gate prone to tilting and jamming. Consequently, a deviation occurs between the actual opening height and the preset opening, affecting the accuracy of flow control and the reliability of the project operation. Utility Model Content

[0029] The present application will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] Please see Figures 1-7 This application provides a hydraulic gate opening calibration device for calibrating gates 7 that have opening errors.

[0031] In this embodiment, refer to Figure 1 The hydraulic gate opening calibration device includes: a gate body 1, a calibration rope 8, a winding assembly 2, a drive assembly 3, and a calibration assembly 4; wherein, one end of the calibration rope 8 is connected to the gate 7; the winding assembly 2 is disposed on the gate body 1 and connected to the other end of the calibration rope 8, and the winding assembly 2 is used to wind up the calibration rope 8; the drive assembly 3 is gear-connected to one end of the winding assembly 2, and the drive assembly 3 provides winding driving force to the winding assembly 2; the calibration assembly 4 is slidably mounted on the gate body 1, and the other end of the calibration assembly 4 is detachably connected to the winding assembly 2; wherein, there are two of each of the calibration rope 8, the winding assembly 2, the drive assembly 3, and the calibration assembly 4, and they are symmetrically arranged in pairs on the gate body 1.

[0032] Specifically, one end of the calibration rope 8 is connected to the gate 7, and the other end is connected to the drive end of the winding assembly 2. The drive assembly 3 provides power to the winding assembly 2 to automatically wind up the calibration rope 8, ensuring that the calibration rope 8 remains taut and is automatically wound up during the normal rise of the gate 7. Operators can directly and clearly observe the winding length of the calibration rope 8, thus providing a direct and accurate observation of the actual opening of the gate 7. When the gate 7 tilts, the calibration assembly 4 intervenes, providing calibration power to the winding assembly 2 and driving it to wind up the calibration rope 8 connected to the lower end of the gate 7, effectively raising the height of that side of the gate 7 until the gate 7 returns to a horizontal state. Subsequently, according to the preset opening target value, the calibration assembly 4 continues to drive the winding assembly 2 to perform the operation of winding and unwinding the calibration rope 8, finely adjusting the overall height of the gate 7. This achieves the correction of the gate 7's tilt and the precise correction of the opening error, ensuring the stability of the gate 7's operation and the reliability of water level regulation.

[0033] See Figure 1 , Figure 4 and Figure 6 In an exemplary embodiment, the gate body 1 may include a top plate 11, two side plates 12, and a mounting plate 13. A lifting assembly 6 is installed on the side of the top plate 11 away from the gate 7. The lifting assembly 6 is connected to the gate 7 and provides a sliding driving force for the gate 7. The two side plates 12 are symmetrically fixedly connected to both ends of the top plate 11 and are arranged perpendicular to the top plate 11. The mounting plate 13 is installed on one side of the two side plates 12 and close to the top plate 11. A sliding groove 121 is opened on the opposite side of the two side plates 12. The gate 7 slides in the sliding groove 121. On the mounting plate 13, two clearance openings 132 are symmetrically opened on the side close to the top plate 11. The clearance openings 132 are used to avoid the calibration rope 8.

[0034] Specifically, the gate 7 slides in the grooves 121 on opposite sides of the two side plates 12. The lifting assembly 6 installed on the top plate 11 provides the sliding driving force for the gate 7. The grooves 121 act as a guide for the sliding of the gate 7, ensuring that the position of the gate 7 will not shift when driven by the lifting assembly 6. The top plate 11 provides the optimal installation position for the lifting assembly 6, ensuring that the driving distance of the lifting assembly 6 when driving the gate 7 to slide is the shortest and the working loss during the driving process is the lowest.

[0035] See Figure 1 and Figure 2In an exemplary embodiment, the winding assembly 2 may include a first rotating shaft 21, a first gear 22, a first winding roller 23, and a fixed pulley 24. One end of the first rotating shaft 21 is rotatably connected to the side plate 12. The first gear 22 is fixedly installed at the end of the first rotating shaft 21 near the side plate 12. One end of the first winding roller 23 is fixedly connected to the end of the first rotating shaft 21 away from the side plate 12. The calibration rope 8 is wound around the first winding roller 23. The end of the first winding roller 23 away from the first gear 22 is detachably connected to the calibration assembly 4. The fixed pulley 24 is installed on the side of the top plate 11 near the gate 7. One end of the calibration rope 8 is fixedly connected to the gate 7, and the other end passes over the fixed pulley 24 and is connected to the first winding roller 23, so that the calibration rope 8 overlaps the fixed pulley 24.

[0036] Specifically, as the opening of the gate 7 increases due to the lifting component 6, the pulling force of the gate 7 on the calibration rope 8 gradually decreases. When the pulling force of the gate 7 on the calibration rope 8 is less than the winding force of the driving component 3, the driving component 3 will drive the first rotating shaft 21 to rotate through the first gear 22, thereby driving the first winding roller 23 to rotate and wind up the calibration rope 8. The fixed pulley 24 effectively changes the direction of the calibration rope 8 and effectively reduces the frictional wear on the calibration rope 8, effectively improving the service life of the calibration rope 8. During the winding process of the calibration rope 8, the operator can quickly determine whether there is an error in the opening of the gate 7 by measuring the winding length of the calibration rope 8 and comparing it with the preset opening. When the gate 7 is in If tilting and jamming occur during the lifting process, and the lifting assembly 6 can no longer drive the gate 7 to slide, the calibration assembly 4 connects with the end of the first take-up roller 23. The calibration assembly 4 provides the first take-up roller 23 with the driving force for the calibration rope 8 at the lower end of the gate 7. The calibration rope 8 pulls up the lower end of the gate 7, adjusting the gate 7 to a horizontal state. The intervention of the calibration assembly 4 provides the driving force for the take-up assembly 2 to calibrate the opening of the gate 7, making the calibration of the gate 7 opening faster and more accurate. Then, the opening of the gate 7 is compared with the preset opening and the actual winding length of the calibration rope 8 to determine whether the opening of the gate 7 is greater or less than the preset opening, so that the gate 7 continues to be lifted or lowered until it is adjusted to the preset opening.

[0037] See Figure 2 and Figure 3 In an exemplary embodiment, the drive assembly 3 may include a spring box 31, a spring 32, a second rotating shaft 33, and a second gear 34. The spring box 31 is fixedly mounted on the gate body 1, and a spring shaft 311 is rotatably connected to the center of the spring box 31. The spring 32 is installed inside the spring box, and the center end of the spring 32 is fixedly connected to the spring shaft 311. The outer edge end of the spring 32 is fixedly connected to the spring box 31. One end of the second rotating shaft 33 extends into the spring box 31 and is coaxially connected to the spring shaft 311. The second gear 34 is fixedly connected to the end of the second rotating shaft 33 away from the spring shaft 311 and meshes with the first gear 22.

[0038] Specifically, the spring 32 is made of a spirally wound metal sheet. When the gate 7 is fully closed, the spring 32 is in a contracted state. When the lifting assembly 6 drives the gate 7 to rise, the pulling force of the gate 7 on the calibration rope 8 gradually decreases. When the pulling force of the gate 7 is less than the force of the spring 32 when it expands and returns to its original state, the spring 32 will drive the spring shaft 311 to rotate. The spring shaft 311 drives the second rotating shaft 33 to drive the second gear 34 to rotate. The second gear 34 drives the first gear 22 to drive the first winding roller 23 to rotate, thereby realizing the automatic winding of the calibration rope 8, so that the calibration rope 8 always remains taut and ensures the accuracy of observing the actual opening of the gate 7.

[0039] It should also be noted that when the gate 7 is closed, the spring 32 is not fully contracted to its tightest state; when the gate 7 is at its maximum opening, the spring 32 is not fully extended to its maximum extent.

[0040] See Figure 4 , Figure 6 and Figure 7 The mounting plate 13 has a moving groove 131 along the length of the top plate 11 on the side near the take-up assembly 2. Two calibration assemblies 4 are slidably installed in the moving groove 131. The calibration assembly 4 includes a push cylinder 41, a moving seat 42, and a drive motor 43. The push cylinder 41 is installed at one end of the moving groove 131 near the side plate 12. The moving seat 42 is slidably connected in the moving groove 131 and fixedly connected to the drive end of the push cylinder 41. The drive motor 43 is fixedly installed on the moving seat 42, and the output end of the drive motor 43 is detachably connected to the first take-up roller 23.

[0041] Specifically, when tilting or jamming occurs during the lifting of the gate 7, the push cylinder 41 pushes the moving seat 42 to move towards one end of the first winding roller 23, causing the drive end of the drive motor 43 to connect with the end of the winding roller. The drive motor 43 provides the first winding roller 23 with the driving force for calibration winding. After the calibration is completed, the push cylinder 41 drives the drive motor 43 to move away from the first winding roller 23. During calibration, the drive motor 43 provides the first winding roller 23 with the power to wind the calibration rope 8 and lift the gate 7. After calibration, the active force on the first winding roller 23 is released, and the first winding roller 23 is returned to the drive assembly 3 to provide the force to wind the calibration rope 8. This allows for timely docking and disassembly, improving the efficiency of opening calibration and gate 7 lifting.

[0042] When the drive motor 43 drives the first take-up roller 23 to take up the winding, it also drives the spring 32 to contract. When the drive motor 43 drives the first take-up roller 23 to release the calibration rope 8, it also drives the spring 32 to release synchronously.

[0043] See Figure 1 and Figure 5 In an exemplary embodiment, the observation component 5 may include two indicator needles 51, an observation slot 53, and an observation block 52. The two indicator needles 51 are respectively fixedly installed at one end of the two calibration ropes 8 near the gate 7. The observation slot 53 is opened through the side plate 12 along the length direction of the side plate 12. A scale line 122 is marked on the side of the side plate 12 away from the gate 7. The scale line 122 is located on both sides of the observation slot 53. An observation block 52 is installed at the end of the indicator needles 51 away from the calibration ropes 8. The observation block 52 and the observation slot 53 are arranged perpendicularly.

[0044] It should be noted that both the indicator needle 51 and the observation block 52 are made of lightweight materials such as plant fibers, and will not fall during movement along the observation groove 53.

[0045] Specifically, when the lifting assembly 6 lifts the gate 7, the first winding roller 23 automatically winds up the calibration rope 8 under the action of the spring 32. The calibration rope 8 drives the indicator needle 51 to move to one side of the lifting assembly 6. The indicator needle 51 drives the observation block 52 to move along the observation groove 53. The height of the gate 7 can be directly observed through the scale lines 122 on both sides of the observation groove 53, so as to know the actual opening degree of the gate 7.

[0046] See Figure 7 The output end of the drive motor 43 is provided with a cross-shaped protrusion 431, and the end of the first take-up roller 23 away from the first gear 22 is provided with a cross-shaped embedding groove 231, and the cross-shaped protrusion 431 can extend into the cross-shaped embedding groove 231.

[0047] Specifically, when the drive motor 43 drives the first take-up roller 23 to calibrate the opening of the gate 7, the drive motor 43 is pushed close to the first take-up roller 23 by the push cylinder 41. The angle of the cross-shaped protrusion 431 at the output end of the drive motor 43 is adjusted to fit into the cross-shaped insertion groove 231 at the end of the first take-up roller 23. This ensures that the first take-up roller 23 can be effectively rotated and wound up when the drive motor 43 drives it. At the same time, after the winding stops, the first take-up roller 23 is not pulled to the opposite direction by the weight of the gate 7 itself, thus ensuring the safety of the gate 7 opening calibration process.

[0048] See Figure 1 In an exemplary embodiment, the lifting assembly 6 may include a lifting motor 61, a second take-up roller 62, and a traction rope 63. The lifting motor 61 is mounted on the side of the top plate 11 away from the gate 7. One end of the second take-up roller 62 is coaxially connected to the drive end of the lifting motor 61, and the other end is rotatably connected to the top plate 11. One end of the traction rope 63 passes through the top plate 11 and is fixedly connected to the gate 7, and the other end is wound around the second take-up roller 62.

[0049] Specifically, when the gate 7 needs to be opened to the preset opening degree, the lifting motor 61 drives the second winding roller 62 to rotate, which in turn drives the traction rope 63 to pull the gate 7. The sliding direction of the traction rope 63 and the gate 7 is set in parallel, which effectively reduces the working loss of the gate 7 during the lifting process. When the gate 7 tilts and gets stuck during the lifting process to the preset opening degree, if the winding force applied by the lifting motor 61 to the second winding roller 62 is insufficient to adjust the opening degree of the gate 7, the driving of the lifting motor 61 is stopped, and the adjustment drive of the gate 7 is handed over to the calibration component 4 to calibrate the gate 7. After the calibration component 4 completes the calibration work, the lifting motor 61 controls the second winding roller 62 to wind or release the traction rope 63 to adjust the traction rope 63 to a suitable length.

[0050] The above are merely preferred embodiments of this application and do not limit the patent scope of this application.
