Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of hydropower stations, in particular to a hydropower station gate. BACKGROUND

[0002] When the conventional hydropower station gate is overhauled, the gate plate is lowered. Due to technical reasons, the equipment has not been started for a long time, or the operator's operation causes the gate plate steel wire rope to be lowered excessively when the gate top control room is operated, which may cause the steel wire rope to be wound. Furthermore, the steel wire rope will still deform after long-term use. Before the gate is lowered, the weight of the gate will still cause a certain deformation of the lowered section of the steel wire rope, thus causing a certain error and resulting in a length that is longer than the actual length. If the above situation of the steel wire rope is not handled in time, the gate plate may not be opened in time after overhaul, the economic loss of the power station is caused, or the phenomenon of the steel wire rope being wound is aggravated due to water flow fluctuation, and the negative influence is greater. At present, in order to prevent the steel wire rope from being wound, manual regular inspection of the steel wire rope is mainly performed.

[0031] The present application provides a water power station gate 100.

[0032] Please refer to Figure 1 and Figure 3 In an embodiment of the present application, the water power station gate 100 comprises a gate plate 1, a crossbeam 2 and an anti-winding device 3, the crossbeam 2 is arranged above the gate plate 1 in the transverse direction, the top of the crossbeam 2 is provided with a traction mechanism, the traction mechanism is connected with the gate plate 1 through a plurality of steel wires 11 passing through the crossbeam 2, and the traction mechanism is used to drive the gate plate 1 to rise and fall through the steel wires 11; the anti-winding device 3 comprises a smoothing plate 31 and a lifting mechanism 32, the smoothing plate 31 is arranged below the crossbeam 2, a plurality of through holes 311 are formed in the smoothing plate 31, the through holes 311 penetrate from the top to the bottom of the smoothing plate 31 in the vertical direction, the number of the through holes 311 is consistent with the number of the steel wires 11 and one-to-one correspondence, and each steel wire 11 is slidably arranged in the corresponding through hole 311; the lifting mechanism 32 is installed at the bottom of the crossbeam 2, the lifting mechanism 32 is connected with the position of the smoothing plate 31 avoiding each through hole 311, and the lifting mechanism 32 is used to drive the smoothing plate 31 to vertically rise and fall, so as to smooth each steel wire 11 through the smoothing plate 31.

[0033] The anti-winding device 3 of the steel wire rope 11 of the water power station gate 100 of the present application adopts the smoothing plate 31 and the lifting mechanism 32, a plurality of through holes 311 are formed on the smoothing plate 31, each steel wire rope 11 passes through a corresponding through hole 311 to separate the steel wire ropes 11, when the traction mechanism lowers the gate plate 1 through the steel wire ropes 11, each steel wire rope 11 descends through the corresponding through hole 311, which can constrain the swing of the steel wire rope 11, thereby combing the steel wire rope 11 during the lifting of the gate plate 1, reducing the risk of winding of the steel wire rope 11; and if the steel wire rope 11 is wound after the gate plate 1 is lowered, the lifting mechanism 32 can also drive the smoothing plate 31 to lift, the smoothing plate 31 actively combs each steel wire rope 11 when moving along the steel wire rope 11, thereby smoothing the wound steel wire rope 11, ensuring the long-term safe and reliable operation of the water power station gate 100, and without relying on manual processing of the wound steel wire rope 11, reducing the labor intensity.

[0034] In actual use, the lifting device drives the smoothing plate 31 to rise and fall multiple times, that is, the steel wire rope 11 is combed and corrected multiple times by the smoothing plate 31, ensuring that the wound steel wire rope 11 is effectively smoothed.

[0035] Understandably, the lifting device can be configured to start periodically, and the smoothing plate 31 is driven to rise and fall to smooth the steel wire rope 11 every certain period of time, ensuring the long-term safe operation of the steel wire rope 11, which can effectively reduce the number of periodic manual inspections and further reduce the labor intensity.

[0036] It should be noted that, as shown in the drawings, Figure 1 The horizontal direction, the vertical direction and the vertical direction in the embodiment are respectively the left-right direction, the front-rear direction and the up-down direction.

[0037] Please refer to Figure 3 In an embodiment, a bushing 312 is arranged in each through hole 311, and the outer side of the bushing 312 abuts against the hole wall of the corresponding through hole 311, each bushing 312 surrounds a channel 3122 extending in the vertical direction, and the two ends of the bushing 312 in the vertical direction form two openings 3121 of the channel 3122 respectively; each steel wire rope 11 passes through a corresponding channel 3122, and the inner diameter of each channel 3122 is greater than the outer diameter of the corresponding steel wire rope 11.

[0038] Understandably, by providing a bushing 312 within the through hole 311, direct friction between the wire rope 11 and the straightening plate 31 is avoided. When the wire rope 11 slides relative to the channel 3122 of the bushing 312, friction mainly occurs between the wire rope 11 and the bushing 312. The bushing 312, made of wear-resistant and self-lubricating materials such as nylon, polytetrafluoroethylene, and copper alloys, significantly reduces the coefficient of friction, effectively reducing wear, fraying, and even wire breakage risks on the surface of the wire rope 11, thereby greatly extending its service life. Furthermore, it protects the straightening plate 31; once the bushing 312 wears out, it can be directly replaced, reducing maintenance costs.

[0039] Understandably, the bushing 312 is fastened in the through hole 311 by being embedded. By making the inner diameter of the channel 3122 of the bushing 312 larger than the outer diameter of the wire rope 11, the contact area between the wire rope 11 and the inner wall of the channel 3122 is reduced, thereby further reducing friction and facilitating the smooth sliding of the wire rope 11 relative to the channel 3122.

[0040] Please see Figure 4 In one embodiment, the inner wall of the channel 3122 and the edges near the two openings 3121 in each bushing 312 are rounded to ensure a smooth transition between the inner wall of the channel 3122 and the two end faces of the bushing 312 forming the two openings 3121. Understandably, the chamfered edges of the bushing 312 near the openings 3121 allow for a smooth transition between the inner wall of the channel 3122 and the two end faces of the bushing 312. During the lifting and lowering of the straightening plate 31, the chamfer provides good guidance for the wire rope 11, preventing it from being caught by the edges of the openings 3121 due to slight deviation from the center of the channel 3122. It also effectively prevents the edges of the bushing 312 near the openings 3121 from scratching the wire rope 11, reducing the risk of scratches, fraying, or breakage on the surface of the wire rope 11, further protecting the integrity of the wire rope 11 and extending its service life.

[0041] Please continue reading. Figure 1 In one embodiment, the bottom of the crossbeam 2 is provided with an installation groove 21, and the lifting mechanism 32 is disposed in the installation groove 21; the bottom of the crossbeam 2 is also provided with a receiving groove 22 that communicates with the installation groove 21, the receiving groove 22 and the straightening plate 31 are matched and disposed, and the lifting mechanism 32 can drive the straightening plate 31 to rise to be received in the receiving groove 22.

[0042] Understandably, by setting the lifting mechanism 32 in the mounting groove 21 at the bottom of the crossbeam 2, the structure is compact, saving external space and preventing the lifting mechanism 32 from being directly exposed to the outside, effectively preventing rainwater from corroding the lifting mechanism 32. When the hydropower station gate 100 is in normal operation, the lifting mechanism 32 can drive the straightening plate 31 to rise and be completely housed in the receiving groove 22 at the bottom of the crossbeam 2. At this time, the straightening plate 31 is hidden inside the crossbeam 2, avoiding its long-term exposure to harsh working conditions such as water splashing, sun and rain, freezing or floating object impact, thereby significantly reducing the risk of corrosion, wear and accidental damage to the straightening plate 31 and extending the service life of the straightening plate 31 and its bushing 312.

[0043] In one embodiment, the lifting mechanism 32 includes two winches 321. Two mounting slots 21 are provided at the bottom of the crossbeam 2, and the two mounting slots 21 are respectively located on opposite sides of the receiving slot 22 in the transverse direction. The two winches 321 are respectively disposed in the two mounting slots 21. Connecting ears 313 are provided at opposite ends of the straightening plate 31. The traction ropes 322 of the two winches 321 are detachably connected to the two connecting ears 313 respectively. Each winch 321 is used to drive the corresponding connecting ear 313 and the straightening plate 31 to move vertically up and down through its traction rope 322.

[0044] Understandably, the lifting mechanism 32 includes two winches 321, which are located on both sides of the receiving groove 22, so that the traction force is applied at two connecting ears 313 at both ends of the straightening plate 31, forming a two-point synchronous lifting / lowering. This ensures that the straightening plate 31 always maintains a horizontal posture during the lifting process and rises and falls smoothly in the vertical direction, preventing the straightening plate 31 from scraping or getting stuck with the wire rope 11 due to tilting, thus improving reliability.

[0045] It should be noted that the winch 321 mentioned above can be a winch 321 in the prior art. When the winch 321 is winding the traction rope 322, it drives the straightening plate 31 to rise. When the winch 321 releases the traction rope 322, the straightening plate 31 descends under its own weight.

[0046] Specifically, each connecting ear 313 has a connecting hole, and the traction rope 322 passes through the corresponding connecting hole and is detachably connected to the corresponding connecting ear 313. The traction rope 322 is, but is not limited to, being securely connected to the connecting ear 313 by knotting.

[0047] Please see Figure 1 and Figure 2In one embodiment, the anti-winding device 3 further includes a support mechanism 33, which is disposed at the bottom of the crossbeam 2 and near the receiving groove 22. The support mechanism 33 includes a support plate 331, a rotating shaft 332 and a driving member. The rotating shaft 332 is arranged vertically. The support plate 331 is connected to the bottom of the rotating shaft 332. The driving member is used to drive the rotating shaft 332 to rotate along its axial direction so that the support plate 331 can rotate around the rotating shaft 332 to abut or disengage from the bottom of the straightening plate 31 located in the receiving groove 22.

[0048] Understandably, when the straightening plate 31 is retracted into the receiving groove 22 by the lifting mechanism 32, the support plate 331 rotates under the action of the driving component to abut against the bottom of the straightening plate 31, thereby supporting the straightening plate 31 and limiting the straightening plate 31 within the receiving groove 22; and the support plate 331 effectively shares the self-weight load of the straightening plate 31 in the stored state, reducing the continuous burden on the traction rope 322, avoiding the slack, fatigue or deformation caused by long-term tension of the traction rope 322, and improving safety and reliability.

[0049] It should be noted that the driving component can be a drive motor from existing technology.

[0050] In one embodiment, the support plate 331 is a fan-shaped support plate 331, which forms a straight edge and a rounded edge 3311. The two vertical sides of the fan-shaped support plate 331 are the top surface and the bottom surface, respectively. The bottom surface is a horizontal surface that is parallel to the bottom surface of the crossbeam 2. The direction from the straight edge of the rotating shaft 332 toward the middle position of the rounded edge 3311 is defined as the reference direction. The top surface is inclined upward along the reference direction so that the distance between the top surface and the bottom surface gradually widens along the reference direction. The middle position of the top surface abuts or disengages from the bottom of the smoothing plate 31.

[0051] Understandably, the straightening plate 31 may have slight positional deviations or dynamic wobbling when retracting into the receiving groove 22, resulting in a height difference between the bottom of the straightening plate 31 and the top of the support plate 331. The top surface of the support plate 331 is inclined upward along the reference direction, so that the middle position of the arc-shaped edge 3311 is high and the two sides are low. When the support plate 331 rotates, one side of the arc-shaped edge 3311 can first move smoothly to the bottom of the straightening plate 31. Then the support plate 331 continues to rotate until the top of the middle position of the arc-shaped edge 3311 abuts against the bottom of the straightening plate 31, thereby supporting the straightening plate 31 and effectively reducing the burden on the traction rope 322.

[0052] In one embodiment, there are two support mechanisms 33, and the two support mechanisms 33 are respectively disposed on opposite sides of the receiving groove 22 along the longitudinal direction. It can be understood that by providing two support mechanisms 33, and the two support mechanisms 33 being disposed on opposite sides of the receiving groove 22, the two support plates 331 support different positions of the straightening plate 31 in the receiving groove 22, which significantly improves the anti-overturning ability and overall stability of the straightening plate 31 in the stored state, and prevents it from tilting.

[0053] Specifically, two support mechanisms 33 are positioned at the midpoints of opposite sides of the straightening plate 31 to maintain its balance. Two winches 321 and two support mechanisms 33 are respectively positioned on different opposite sides of the receiving groove 22. In this embodiment, the two winches 321 are respectively positioned at both ends of the receiving groove 22 along its length direction, so that the two winches 321 apply an upward force to both ends of the straightening plate 31 along its length direction; the two support plates 331 are respectively located at both ends of the receiving groove 22 along its width direction to support both ends of the straightening plate 31 along its width direction, thereby maintaining the balance of the straightening plate 31 during storage.

[0054] In one embodiment, a distance sensor 34 for testing the distance between the straightening plate 31 and the top of the gate plate 1 is provided at the bottom of the straightening plate 31. By setting up a control module and a distance sensor 34, the distance sensor 34 can monitor the relative distance between the straightening plate 31 and the gate plate 1 in real time and continuously, and can then use additional warning devices, such as buzzers and audible and visual alarms, to remind the user to prevent the straightening plate 31 from colliding with the gate plate 1.

[0055] Furthermore, the anti-entanglement device 3 also includes a control module, which is located at the bottom of the crossbeam 2 and electrically connected to the lifting mechanism 32. The control module is also electrically connected to the distance sensor 34. Understandably, by setting the control module, the distance sensor 34 can monitor the relative distance between the straightening plate 31 and the gate 1 in real time and continuously, generating a position feedback signal which is sent to the control module. After receiving this signal, the control module can adjust the operating state of the lifting mechanism 32, including start / stop, speed, and raising or lowering, to achieve automated control. The control module can set a safe distance threshold. When the straightening plate 31 approaches the gate 1 to a set distance, the control module can control the lifting mechanism 32 to stop or change the moving direction of the straightening plate 31 to avoid a rigid collision between the straightening plate 31 and the gate 1.

[0056] It should be noted that the control module can be a PLC or other existing technology, and the ranging sensor 34 can be an ultrasonic sensor, laser rangefinder or infrared sensor or other existing technology.

[0057] Understandably, one specific process is as follows: the lifting mechanism 32 is started by the control module, and the lifting mechanism 32 drives the straightening plate 31 to descend. The distance sensor 34 at the bottom of the straightening plate 31 monitors the distance between the straightening plate 31 and the top of the gate plate 1 in real time and feeds it back to the control module. When the distance between the straightening plate 31 and the top of the gate plate 1 is less than or equal to the set distance, the control module controls the lifting mechanism 32 to drive the straightening plate 31 to rise. When the distance between the straightening plate 31 and the top of the gate plate 1 is greater than or equal to the set distance, the control module controls the lifting mechanism 32 to drive the straightening plate 31 to descend. In this way, by driving the straightening plate 31 to rise and fall multiple times, the wire rope 11 is straightened, effectively solving the problem of wire rope 11 entanglement.

[0058] In one embodiment, the hydropower station gate 100 further includes two columns 4, which are spaced apart laterally. A crossbeam 2 is supported on the top of the two columns 4. Each of the two columns 4 has a vertically extending groove 41 on its opposite side. The gate plate 1 can be slidably inserted into the two grooves 41 at its opposite ends laterally. By providing grooves 41 on the columns 4, the gate plate 1 can be slidably inserted into the two grooves 41 at its opposite ends laterally. When the traction mechanism drives the gate plate 1 to rise and fall, the grooves 41 limit and guide the gate plate 1, preventing the gate plate 1 from shifting position and improving reliability.

[0059] The above description is merely an exemplary embodiment of the present invention and does not limit the scope of protection of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
