Description

Technical Field

[0001] This application relates to the field of hydraulic gate technology, and in particular to a gate ring locking device with multiple locking angle options. Background Technology

[0002] In the field of water conservancy engineering, gates are key structures for regulating water flow and controlling water levels. Their stable and reliable locking mechanisms are directly related to the safety and operational efficiency of the entire water conservancy system.

[0003] Traditional locking devices are often designed based on a few preset fixed angles (such as 90 degrees and 180 degrees), making it difficult to adjust them in real time according to water flow conditions, water level fluctuations, or emergency dispatch needs. This rigid design reduces the gate's adaptability to different operating conditions, affecting the flexible dispatch and emergency response capabilities of water conservancy projects. Because the locking angle is fixed, when the gate position needs to be adjusted to adapt to new operating conditions, it may be necessary to replace the locking device or make complex mechanical adjustments. This not only increases the complexity and time cost of maintenance work, but also increases the economic burden of long-term operation. Utility Model Content

[0004] The purpose of this application is to provide a gate ring locking device with multiple locking angle options, which solves the problem that the existing gate locking devices have limited locking angles and cannot achieve precise control of the gate rotation angle.

[0005] To achieve the above objectives / to solve the above technical problems, this application adopts the following technical solution:

[0006] This application provides a gate ring locking device with multiple locking angle selection, including: a fixed frame, wherein the fixed frame is provided with a rotating shaft fixing hole;

[0007] A rotating shaft is rotatably connected to the fixing hole of the rotating shaft;

[0008] A sleeve is fitted onto the rotating shaft. One end of the sleeve is connected to the rotating shaft, and the other end is rotatably connected to the fixed frame. There is a sandwich between the sleeve and the rotating shaft, and a gate is disposed on the sleeve.

[0009] A drive assembly for driving the rotating shaft to rotate;

[0010] A locking component, disposed within the interlayer, includes a locking ring, a locking pin, and a first driving member. The locking ring is sleeved on the rotating shaft, and multiple locking holes are axially arranged around the locking ring. One end of the first driving member is connected to the fixed frame, and the other end is connected to the locking pin. The first driving member is used to drive the locking pin to move, so that the locking pin is inserted into or disengaged from the locking hole.

[0011] The gate ring locking device in this solution, featuring multiple locking angle options, allows for flexible adjustment of the gate's locking angle. Specifically, when the gate's opening and closing angle needs adjustment, the drive assembly activates, driving the rotating shaft to rotate. The rotation of the shaft causes the connected sleeve to rotate as well. Since the gate is mounted on the sleeve, the rotation of the sleeve further drives the gate to open or close. When the gate rotates to the desired angle, it needs to be locked to maintain its current position. At this time, the first drive component in the locking assembly begins to operate. The first drive component is connected to one side of the fixed frame and remains stationary. The first drive component drives the locking pin to move along a preset trajectory until the locking pin is precisely aligned and inserted into the locking hole on the locking ring. The insertion of the locking pin locks the rotating shaft (and the connected sleeve and gate) at the current angle. In this solution, the locking assembly is located in the interlayer between the sleeve and the rotating shaft. This interlayer is sealed, effectively preventing the intrusion of external water flow, silt, and other impurities. This not only protects the locking assembly from damage but also ensures the accuracy and reliability of the locking action. The locking ring is connected to the rotating shaft and rotates synchronously with the shaft. The locking ring has multiple locking holes, all of which can rotate into the movement path of the locking pin. Regardless of the gate's angle, there is always a locking hole corresponding to the locking pin, maintaining a relative position with the fixed-position locking pin. By adjusting the insertion of the locking pin into different locking holes on the locking ring, the gate can be locked at different angles. This flexibility meets the scheduling needs of various operating conditions in water conservancy projects.

[0012] Optionally, the first driving component is provided with a pin sleeve, one end of which is provided with a U-shaped connecting part, which is sleeved on the locking ring, and one end of which is connected to a lock body; the locking pin is located inside the pin sleeve, and the locking pin and the lock body are respectively located on both sides of the locking ring, and the lock body is provided with a hole corresponding to the locking pin.

[0013] During the insertion of the locking pin into the keyhole, the tilted gate generates a force that is directly transmitted to the locking pin via the locking ring. Over time, this force can cause the locking pin to bend and deform, making alignment between the pin and the keyhole difficult. To address this issue, this solution incorporates pin sleeves and a lock body on both sides of the locking ring. When the tilted gate exerts force on the locking pin, the stress that would otherwise act directly on the pin is distributed across the pin sleeves and lock body. This effectively reduces the stress on the locking pin, preventing bending and deformation due to prolonged stress. This not only extends the lifespan of the locking pin but also improves the stability and reliability of the entire locking system.

[0014] Optionally, the drive assembly includes a base, a second drive member, and a drive arm. The second drive member is rotatably connected to the base, and one end of the drive arm is rotatably connected to one end of the second drive member, while the other end passes through the sleeve and is connected to the rotating shaft.

[0015] The base, serving as the supporting structure for the entire drive assembly, ensures its stability and reliability. The second drive component provides the power to rotate the drive shaft. Rotatably connected to the base, the second drive component allows for flexible rotation and power transmission to the drive arm. The drive arm, acting as a bridge between the second drive component and the shaft, plays a crucial role in power transmission; one end is rotatably connected to the second drive component, and the other end passes through a sleeve and connects to the shaft. This allows the rotation of the second drive component to directly drive the drive arm and shaft, thereby opening and closing the gate.

[0016] When the gate needs to be opened or closed, the second drive unit starts to operate and rotates. The rotating second drive unit transmits power to the rotating shaft through the drive arm. The rotating shaft rotates accordingly, causing the connected sleeve and gate to rotate together. When the gate rotates to the desired position, the locking assembly starts to operate and locks the gate at the current angle.

[0017] Optionally, the system also includes an equipment compartment located at the bottom of the gate, with the drive assembly situated inside the compartment and the gate located outside. The equipment compartment houses the drive assembly, isolates the water flow, and provides space for maintenance of the drive assembly.

[0018] The equipment compartment is located at the bottom of the gate, specifically below the gate itself. The equipment compartment isolates the drive components from water flow and other external factors, extending their service life. It can be constructed from robust and durable materials such as steel or concrete to ensure it can withstand water pressure and other external forces. Sufficient space is provided inside the equipment compartment to house the drive components, ensuring adequate room for operation and maintenance.

[0019] Optionally, the second driving component is an oil pump.

[0020] Optionally, the top of the equipment compartment has a limiting wall, which is used to limit the rotation range of the drive arm.

[0021] This design limits the rotation range of the drive arm using a limiting wall. When the drive arm rotates to a certain angle, it will come into contact with the limiting wall, preventing further rotation. This avoids unnecessary contact between the plunger and the sleeve during the extension of the drive arm driven by the oil pump, and also prevents the plunger and drive wall from forming a straight line in the radial direction of the rotating shaft during the retraction of the oil pump, which could lead to jamming and equipment malfunction.

[0022] Optionally, it may also include a PLC controller, which is signal-connected to the first drive and the second drive.

[0023] This solution uses a PLC controller to control the extension of the second drive component, thereby controlling the gate's rotation angle. The PLC controller then controls the first drive component, ensuring the locking pin can smoothly insert into the lock hole. Intelligent control via the PLC controller ensures that when the gate rotates to different angles, a corresponding lock hole rotates onto the locking pin's path. The PLC controller can precisely adjust the extension of the second drive component, achieving fine-grained control of the gate's rotation angle. This ensures the gate can accurately open or close to the predetermined position. Simultaneously, the PLC controller controls the first drive component, ensuring that the corresponding lock hole rotates precisely onto the locking pin's path at each rotation angle, ensuring the locking pin can smoothly insert into the lock hole.

[0024] Compared with existing technologies, the beneficial effects achieved by this application are as follows: This utility model uses a drive assembly to rotate a shaft to open and close the gate. When the gate rotates to the required angle, the first drive component in the locking assembly drives the locking pin to insert into the locking hole on the locking ring, thereby locking the shaft. By adjusting the position of the locking pin in the locking hole on the locking ring, the gate can be locked at different angles. This meets the scheduling needs under different working conditions in water conservancy projects. Furthermore, the locking assembly in this device is located in the interlayer between the sleeve and the shaft. This interlayer is sealed, effectively isolating external water flow, silt, and other impurities from intrusion. This not only protects the locking assembly from damage but also ensures the accuracy and reliability of the locking action. Attached Figure Description

Detailed Implementation

[0030] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure / application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use.

[0031] Example 1

[0032] This embodiment describes a gate ring locking device with multiple locking angle selections, referencing... Figure 1 and Figure 2 The gate ring locking device with multiple locking angle selection in this embodiment

[0033] The system includes a fixed frame 1 with a rotating shaft fixing hole 11. A rotating shaft 2 is housed within the rotating shaft fixing hole 11. A sleeve 3 is fitted onto the rotating shaft 2, with one end connected to the rotating shaft 2 and the other end rotatably connected to the fixed frame 1. A sandwich structure exists between the sleeve 3 and the rotating shaft 2, and a gate 7 is mounted on the sleeve 3. The system also includes a drive assembly 4 for driving the rotating shaft. Furthermore, a locking assembly 5 is provided within the sandwich structure. The locking assembly includes a locking ring 51, a locking pin 52, and a first drive member 54. The locking ring 51 is fitted onto the rotating shaft 2, and multiple locking holes 53 are axially arranged around the locking ring 51. One end of the first drive member 54 is connected to the fixed frame 1, and the other end is connected to the locking pin 52, the end of which has a chamfer. The first drive member 54 drives the locking pin to move, causing the locking pin to insert into or disengage from the locking holes 53.

[0034] When adjusting the opening and closing angle of the gate 7, the drive assembly 4 is activated, driving the rotating shaft 2 to rotate. The rotation of the shaft 2 causes the connected sleeve 3 to rotate as well. Since the gate 7 is mounted on the sleeve 3, the rotation of the sleeve 3 further drives the gate 7 to open or close. When the gate 7 reaches the desired angle, it needs to be locked to maintain its current position. At this time, the first drive member 54 in the locking assembly 5 begins to operate. The first drive member 54 is connected to one side of the fixed frame 1 and remains stationary. The first drive member 54 drives the locking pin 52 to move along a preset trajectory until the locking pin 52 is precisely aligned and inserted into the locking hole 53 on the locking ring 51. The insertion of the locking pin 52 locks the rotating shaft 2 (and the connected sleeve 3 and gate 7) at the current angle. In this design, the locking assembly 5 is located in the interlayer between the sleeve 3 and the rotating shaft 2. This interlayer is sealed, effectively preventing the intrusion of external water flow, sediment, and other impurities. This design not only protects the locking assembly 5 from damage but also ensures the accuracy and reliability of the locking action. The locking ring 51 is connected to the rotating shaft 2 and rotates synchronously with the shaft 2. The locking ring has multiple locking holes 53, all of which can rotate into the movement path of the locking pin 52. Regardless of the angle of the gate 7, there is always a locking hole 53 corresponding to the locking pin 52 that maintains a relative position to the fixed-position locking pin 52. By adjusting the insertion of the locking pin 52 into different locking holes 53 on the locking ring 51, the gate 7 can be locked at different angles. This flexibility meets the scheduling needs of different operating conditions in water conservancy projects.

[0035] refer to Figure 3 In this embodiment, a pin sleeve 55 is provided on the first driving member 54. A U-shaped connecting part 56 is provided at one end of the pin sleeve 55. The connecting part 56 is sleeved on the locking ring 51, and a lock body 57 is connected to one end of the connecting part 56. The locking pin 52 is located inside the pin sleeve 55. The locking pin 52 and the lock body 57 are located on both sides of the locking ring 51, and the lock body 57 is provided with a corresponding insertion hole for the locking pin 52.

[0036] During the insertion of the locking pin 52 into the lock hole 53, the gate 7 is tilted, generating a force that is directly transmitted to the locking pin 52 via the locking ring 51. Prolonged exposure to this force may cause the locking pin 52 to bend and deform, leading to difficulty in aligning it with the lock hole 53. To address this issue, this solution incorporates pin sleeves 55 and lock bodies 57 on both sides of the locking ring 51. When the tilted gate 7 exerts force on the locking pin 52, the stress that would otherwise act directly on the locking pin 52 is distributed to the pin sleeves 55 and lock bodies 57. This effectively reduces the stress on the locking pin 52, preventing it from bending and deforming due to prolonged stress. This not only extends the service life of the locking pin 52 but also improves the stability and reliability of the entire locking system.

[0037] Example 2:

[0038] Based on the same inventive concept as Embodiment 1, refer to Figure 1 In this embodiment, the drive assembly 4 includes a base 41, a second drive member 42, and a drive arm 43. In this embodiment, the second drive member 42 is an oil pump. The oil pump is rotatably connected to the base 41, and one end of the drive arm 43 is rotatably connected to the output end of the oil pump, while the other end passes through the sleeve 3 and is connected to the rotating shaft 2.

[0039] In this embodiment, the base 41 serves as the supporting structure for the entire drive assembly 4, ensuring the stability and reliability of the drive assembly 4. The second drive member 42 provides the power to drive the rotating shaft 2. The second drive member 42 is rotatably connected to the base 41, ensuring that it can rotate flexibly and transmit power to the drive arm 43. The drive arm 43, as a bridge connecting the second drive member 42 and the rotating shaft 2, plays a key role in transmitting power. One end of it is rotatably connected to the second drive member 42, and the other end passes through the sleeve 3 and is connected to the rotating shaft 2. Thus, the rotation of the second drive member 42 can directly drive the drive arm 43 and the rotating shaft 2 to rotate, thereby realizing the opening and closing of the gate 7. When it is necessary to open or close the gate 7, the second drive member 42 starts to work and rotates. The rotating second drive member 42 transmits power to the rotating shaft 2 through the drive arm 43. The rotating shaft 2 rotates accordingly, driving the sleeve 3 and the gate 7 connected to it to rotate together. When the gate 7 rotates to the required position, the locking assembly 5 starts to work and locks the gate 7 at the current angle.

[0040] This embodiment also includes an equipment compartment 6, which is located at the bottom of the gate. The drive assembly 4 is located inside the equipment compartment 6, and the gate 7 is located outside the equipment compartment 6. The equipment compartment 6 is located at the bottom of the gate, specifically below the gate 7. The equipment compartment 6 isolates the drive assembly 4 from water flow and other external factors, extending its service life. The equipment compartment 6 can be made of robust and durable materials, such as steel or concrete, to ensure it can withstand water pressure and other external forces. Sufficient space is provided inside the equipment compartment 6 to house the drive assembly 4, ensuring adequate space for its operation and maintenance.

[0041] This embodiment limits the rotation range of the drive arm 43 using a limiting wall. Specifically, the top of the equipment compartment 6 has a limiting wall 61, which restricts the rotation range of the drive arm 43. When the drive arm 43 rotates to a certain angle, it will come into contact with the limiting wall 61, preventing further rotation. This avoids unnecessary contact between the plunger and the sleeve 3 during the extension of the drive arm 43 driven by the oil pump. It also prevents the plunger and the drive wall from forming a straight line in the radial direction of the rotating shaft 2 during the retraction of the oil pump, thus avoiding jamming and preventing the equipment from operating.

[0042] This embodiment also utilizes a PLC controller to achieve precise coordination between the first drive component 54 and the second drive component 42. Specifically, the PLC controller is signal-connected to both the first drive component 54 and the second drive component 42. The PLC controller controls the extension of the second drive component 4, thereby controlling the rotation angle of the gate 7. The PLC controller then controls the first drive component 54 to ensure that the locking pin 52 can be smoothly inserted into the locking hole 53. Intelligent control is achieved through the PLC controller, ensuring that when the gate 7 rotates at different angles, a corresponding locking hole 53 rotates onto the path of the locking pin 52. The PLC controller can precisely adjust the extension of the second drive component 4, thereby achieving detailed control over the rotation angle of the gate 7. This ensures that the gate 7 can be accurately opened or closed to a predetermined position. Simultaneously, the PLC controller controls the first drive component 54 to ensure that the corresponding locking hole 53 rotates precisely onto the path of the locking pin 52 at the desired rotation angle, ensuring that the locking pin 52 can be smoothly inserted into the locking hole 53.

[0043] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this disclosure / application, and these improvements and modifications should also be considered within the protection scope of this disclosure / application.
