Description

Technical Field

[0001] This invention relates to the field of gate technology, and specifically to a hydraulic engineering gate with automatic flow diversion and pressure relief function. Background Technology

[0002] Water conservancy project gates are key equipment installed on the openings of hydraulic structures (such as dams, sluices, dikes, tunnels, canals, etc.) to control water levels, regulate flow, and discharge silt or floating debris.

[0003] Chinese patent CN115679904A discloses a hydraulic engineering gate with automatic flow diversion and pressure relief function; it includes an upper pressure plate, a lower pressure plate, a third support spring, and a hollow lever; when the water flow hits the upper pressure plate, it works with the hollow lever to push the lower pressure plate away from the gate, which is converted into the impact force of the river surface acting on the upper pressure plate, changing the transmission direction of the impact force, applying a reverse force to the bottom of the river, weakening the pressure of the river acting on the gate body, and improving the stability of the gate.

[0004] However, the existing technology has the following drawbacks: after being impacted by the water flow, the upper pressure plate will compress the third spring to achieve buffering. However, the third spring will vibrate back and forth under the combined action of inertia and elastic restoring force, thereby causing high-frequency vibration force on the gate and reducing the stability brought by the spring buffering impact force. In addition, the existing technology uses drugs to degrade pollutants in the silt and then uses a siphon to extract and clean the silt at the bottom of the gate. The degradation takes a certain amount of time to reduce the silt cleaning efficiency. Furthermore, the siphon is prone to blockage during the silt extraction process, resulting in an unstable silt cleaning effect. Summary of the Invention

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a hydraulic engineering gate with automatic flow diversion and pressure relief function.

[0006] The technical solution of the present invention: a hydraulic engineering gate with automatic flow diversion and pressure relief function, comprising:

[0007] The gate mechanism includes a gate body, hydraulic cylinders, a transmission unit, a hinge unit, and plate a. The gate body is hollow and has a discharge port. The gate body has two sets of hydraulic cylinders connected to the riverbank via the hinge unit. Two sets of hydraulic cylinders are located on the riverbank and are connected to the gate body via the transmission unit. Plate a is located at the bottom of the river to seal the bottom of the gate body.

[0008] The buffer dredging mechanism includes a drive unit, a conveying unit, plate b, plate c, a fixing block, a connecting arm, a U-shaped plate, and a telescopic component a. Two fixing blocks are provided and connected to the gate. One end of the fixing block is rotatably connected to the connecting arm. The other end of the connecting arm is rotatably connected to one end of the conveying unit. The U-shaped plate is connected to the other end of the conveying unit. The telescopic component a is located inside the gate body, and its telescopic end is rotatably connected to the U-shaped plate. The drive unit is connected to the conveying unit and located at the discharge outlet. Multiple plates b are provided and fitted together; plate b is detachably connected to the conveying unit. Plate c is connected to plate b.

[0009] A box is detachably connected to the gate body, and an inclined seat for guiding silt is provided at the top of the gate body.

[0010] Preferably, the two sets of gate bodies that are closed to each other are V-shaped with their openings facing downstream of the river; an airbag is provided at the bottom of the gate body.

[0011] Preferably, the transmission unit includes a guide rod, a slider, and an adapter block; the guide rod is connected to the gate body; the slider is slidably connected to the guide rod; the adapter block is rotatably connected to the slider; and the adapter block is connected to the hydraulic cylinder.

[0012] Preferably, the hinged part includes a mounting column, shaft a, and a transfer pipe; the mounting column is connected to the riverbank; the transfer pipe is provided in two sets and is respectively connected to both ends of the mounting column; shaft a is rotatably connected to the transfer pipe; the gate body is connected to shaft a.

[0013] Preferably, the conveying section has two sets arranged symmetrically. The conveying section includes a triangular plate, plate d, plate e, synchronous toothed belt a, synchronous pulley a, synchronous pulley b, and tensioning pulley. There are two sets of synchronous pulley b, and the two sets of synchronous pulley b are rotatably connected to the U-shaped plate and the connecting arm respectively through a rotating shaft. The triangular plate is connected to the U-shaped plate through plate d. The triangular plate is connected to one end of plate e. The other end of plate e is rotatably connected to the rotating shaft. The triangular plate is rotatably connected to the synchronous pulley a and the tensioning pulley. The tensioning pulley is symmetrically arranged about the synchronous belt gear. The synchronous toothed belt a is connected to the surfaces of the synchronous pulley a and the synchronous pulley b.

[0014] Preferably, a plurality of conveying blocks are uniformly connected to the surface of the synchronous toothed belt a; a T-shaped plate is detachably connected to the conveying block; the T-shaped plate is detachably connected to the plate b.

[0015] Preferably, the drive unit includes a plate f, a synchronous pulley c, a synchronous pulley d, a synchronous toothed belt b, and an impeller; the synchronous pulley c is rotatably connected to the plate f; the plate f is connected to the U-shaped plate; the synchronous pulley d is coaxially connected to the synchronous pulley a; and the impeller is coaxially connected to the synchronous pulley c.

[0016] Preferably, a U-shaped sealing frame is connected to the gate body at the outlet; a telescopic component b is connected to the gate body; and a water-blocking block adapted to the U-shaped sealing frame is connected to one end of the telescopic component b.

[0017] Compared with the prior art, the above-mentioned technical solution of the present invention has the following beneficial technical effects:

[0018] By incorporating a gate mechanism, two sets of closed hollow gate bodies form a "V" shape with the opening facing downstream. When the gate body is closed, the upstream water pushes the gate body, helping it close and reducing the work done by the hydraulic cylinder. At the same time, the continuous pushing force of the water on the gate body can improve the tightness of the gate body closure.

[0019] By incorporating a buffer dredging mechanism, the conveying section drives plate b to tilt, transforming the impact of the water flow into an upward climb along the slope. This process decomposes a portion of the forward impact force into an upward component along the slope, greatly reducing the normal pressure perpendicular to the slope. This achieves the buffering function of the upstream water impact force, while preventing high-frequency vibration forces on the gate body and ensuring the stability of the gate body.

[0020] In addition, during the pressure-pressing process of the gate body, the water flow force is used to drive the conveying part to rotate plate b, thereby realizing the function of conveying the silt obliquely upward, and thus realizing the self-cleaning function of the silt in front of the gate. There is no need to degrade the silt, which significantly improves the silt cleaning efficiency and avoids silt blockage, ensuring the stability of silt cleaning. Attached Figure Description

[0032] Example 1, as Figures 1-6 As shown, the present invention proposes a hydraulic engineering gate with automatic flow diversion and pressure relief function, which includes a gate mechanism and a buffer dredging mechanism;

[0033] The gate mechanism includes a gate body 1, a hydraulic cylinder 13, a transmission unit, a hinge unit, and a plate a6. The gate body 1 is hollow, and an airbag 5 is provided at the bottom of the gate body 1 (the airbag 5 is made of materials such as aramid (e.g., Kevlar), ultra-high molecular weight polyethylene (UHMWPE), and carbon fiber, combining lightweight and tear resistance; the surface of the airbag 5 is coated with a wear-resistant layer and a puncture-resistant layer, such as silicone / polyurethane reinforcement). The hollow gate body 1 is lightweight and has a certain buoyancy. With the buoyancy of the airbag 5, the buoyancy of the gate body 1 can be significantly enhanced, thereby reducing the weight borne by the hinge unit and extending the service life of the hinge unit. A discharge port 101 is provided on the gate body 1. The gate body 1 has two sets and is connected to the riverbank through the hinge unit. The two sets of gate bodies 1 that close to each other are V-shaped and their openings face downstream of the river. This ensures that the flow of upstream water can generate thrust on the gate body 1, helping the gate body 1 to close together. At the same time, the flow of upstream water can also exert a thrust on the gate body 1. The thrust generated by body 1 can improve the tightness of the gate body 1 closure; two sets of hydraulic cylinders 13 are provided and located on the riverbank. The hydraulic cylinders 13 are connected to the gate body 1 through a transmission part, which includes a guide rod 30, a slider 29, and a transition block 24; the guide rod 30 is connected to the gate body 1; the slider 29 is slidably connected to the guide rod 30; the transition block 24 is rotatably connected to the slider 29; the transition block 24 is connected to the hydraulic cylinder 13; the hydraulic cylinder 13 pulls the transition block 24 to move in the direction of the hydraulic cylinder 13, the transition block 24 pulls the slider 29 to move, and the slider 29 pulls the gate body 1 to rotate through the guide rod 30, so that the mutually closed gate bodies 1 open; conversely, the hydraulic cylinder 13 pushes the transition block 24 to move, so that the gate bodies 1 close together; plate a6 is located at the bottom of the river to seal the bottom end of the gate body 1. Plate a6 is provided with protrusions adapted to the hinge part and arc grooves to fill the gap between plate a6 and the hinge part, ensuring the sealing between the two (refer to Figure 4 ).

[0034] The hinged section includes a mounting column 2, a shaft a3, and a connecting pipe 4. The mounting column 2 is connected to the riverbank. Two sets of connecting pipes 4 are respectively connected to both ends of the mounting column 2. The shaft a3 is rotatably connected to the connecting pipe 4. The gate body 1 is connected to the shaft a3. The mounting column 2 is embedded inside the riverbank to ensure the sealing between the mounting column 2 and the riverbank. An arc-shaped groove is provided on the mounting column 2 to fit tightly against the surface of the shaft a3. This ensures that the shaft a3 always forms a sealing relationship with the mounting column 2 during rotation. Similarly, an arc-shaped groove is also provided at the contact point between the gate body 1 and the connecting pipe 4. The arc-shaped groove fits tightly against the outer surface of the connecting pipe 4. The inner wall of the arc-shaped groove is provided with a rubber layer made of nitrile rubber. Nitrile rubber is a commonly used and excellent material in sliding seals, with advantages such as wear resistance, oil resistance, and high cost-effectiveness. This ensures that the gate body 1 always forms a sealing relationship with the connecting pipe 4 during rotation. Thus, the gate body 1 is connected to the hinged section while ensuring sealing, preventing water from flowing away through the gap between the two.

[0035] A U-shaped sealing frame 11 is connected to the gate body 1 at the discharge port 101; a telescopic component b9 is connected to the gate body 1; one end of the telescopic component b9 is connected to a water-blocking block 10 adapted to the U-shaped sealing frame 11 (the telescopic component b9 includes, but is not limited to, devices such as cylinders); the telescopic component b9 drives the water-blocking block 10 to move upward away from the U-shaped sealing frame 11, thereby opening the discharge port 101; so that the water accumulated upstream can be discharged into the downstream through the discharge port 101, thereby balancing the water pressure on both sides of the gate body 1 and facilitating the opening of the gate body 1.

[0036] The buffer dredging mechanism includes a drive unit, a conveying unit, plate b14, plate c15, a fixing block 18, a connecting arm 19, a U-shaped plate 20, and a telescopic component a12; two fixing blocks 18 are provided and connected to the gate; one end of the fixing block 18 is rotatably connected to one end of the connecting arm 19; the other end of the connecting arm 19 is rotatably connected to one end of the conveying unit; the U-shaped plate 20 is connected to the other end of the conveying unit; the telescopic component a12 is located inside the gate body 1 and its telescopic end is rotatably connected to the U-shaped plate 20 (see reference). Figure 6 and Figure 8 The telescopic component a12 includes, but is not limited to, devices such as cylinders); the drive unit is connected to the conveying unit and located at the drain outlet 101; multiple plates b14 are provided and are fitted together, and plates b14 are detachably connected to the conveying unit; plates c15 are connected to plates b14; a box 8 is detachably connected to the gate body 1, and an inclined seat 7 for guiding silt is provided at the top of the gate body 1.

[0037] It is worth noting that plates b14 and c15 are both lightweight plates, and the manufacturing materials include, but are not limited to, glass fiber composite materials, which can significantly reduce the overall mass of the conveying section and thus reduce the load of the conveying section on the gate body 1.

[0038] It should be noted that when the gate bodies 1 need to be closed, the bottom of the conveying part is moved horizontally by the telescopic component a12. Under the action of the rotating connection between the connecting arm 19 and the conveying part, the originally vertical conveying part becomes inclined. The plate b14 connected to the conveying part also becomes inclined. When the upstream water hits the inclined plate b14, the inclined plate b14 acts like a ramp, turning the impact of the water flow into an upward climb along the ramp. This process decomposes a part of the forward impact force into an upward component along the ramp, greatly reducing the normal pressure perpendicular to the ramp. After the water flow climbs to the top of the ramp, it usually falls back and collides, mixes and tumbles with the water flow that continues to climb, forming a complex vortex. This process further consumes its total energy, thereby achieving the buffering function of the water flow impact, while not causing high-frequency vibration to the gate body 1, ensuring the stability of the gate body 1.

[0039] When the upstream water flows towards the gate body 1, it also carries silt and other impurities to the gate body 1. The conveying unit, together with plate b14, can block most of the silt and impurities in front of the gate body 1, avoiding a large amount of silt accumulation in front of the gate body 1 and significantly reducing the corrosion of the gate body 1 by the silt. When the outlet 101 is opened and the upstream water is discharged, it will provide driving force to the drive unit, causing the drive unit to drive the conveying unit to work. The operation of the conveying unit will cause plate b14 to drive plate c15 to perform reciprocating conveying action, thereby conveying the silt accumulated at plate b14 obliquely upward. When the silt is conveyed to the top of the gate body 1, it falls into the box 8 for recycling under the guidance of the inclined seat 7.

[0040] Example 2, as Figures 7-10 As shown, this invention proposes a hydraulic engineering gate with automatic flow diversion and pressure relief function. Compared with Embodiment 1, this embodiment further details the structure of the drive unit and the conveying unit. The conveying unit has two sets arranged symmetrically. The conveying unit includes a triangular plate 25, a plate d31, a plate e26, a synchronous toothed belt a16, a synchronous pulley a23, a synchronous pulley b21, and a tensioning wheel 22. There are two sets of synchronous pulleys b21, and the two sets of synchronous pulleys b21 are rotatably connected to the U-shaped plate 20 and the connecting arm 19 respectively through a rotating shaft. The triangular plate 25 is connected to the U-shaped plate 20 through the plate d31. Triangular plate 25 is connected to one end of plate e26; the other end of plate e26 is rotatably connected to the rotating shaft; triangular plate 25 is rotatably connected to synchronous pulley a23 and tensioning pulley 22; tensioning pulley 22 is symmetrically arranged about the synchronous belt gear; synchronous toothed belt a16 is connected to the surface of synchronous pulley a23 and synchronous pulley b21; multiple conveying blocks 28 are evenly connected to the surface of synchronous toothed belt a16; T-shaped plate 27 is detachably connected to conveying block 28; T-shaped plate 27 is detachably connected to plate b14 (the detachable connection method includes, but is not limited to, connection by bolts).

[0041] The drive unit includes a plate f, a synchronous pulley c, a synchronous pulley d, a synchronous toothed belt b, and an impeller 17; the synchronous pulley c is rotatably connected to the plate f; the plate f is connected to the U-shaped plate 20; the synchronous pulley d is coaxially connected to the synchronous pulley a23; and the impeller 17 is coaxially connected to the synchronous pulley c.

[0042] It should be noted that the impeller 17 is located near the discharge outlet 101. When the upstream water is discharged through the discharge outlet 101, the water flow will drive the impeller 17 to rotate. The impeller 17 drives the synchronous pulley c to rotate. The synchronous pulley c drives the synchronous pulley d to rotate through the synchronous toothed belt b. The synchronous pulley d drives the synchronous pulley a23 to rotate. The synchronous pulley a23 drives the synchronous toothed belt a16 to rotate. The synchronous toothed belt a16 drives the plates b14 at various locations to rotate synchronously, forming a conveying action. This enables the oblique conveying function of the silt accumulated on the plates b14, thereby realizing the self-cleaning function of the silt in front of the gate. There is no need to degrade the silt, which significantly improves the silt cleaning efficiency and avoids silt blockage, ensuring the stability of silt cleaning.

[0043] It is worth noting that plate c15 is placed on plate d31 to prevent the sludge from sliding down during the upward oblique transport process.

[0044] In summary, when it is necessary to close the gate bodies 1 on both sides, the hydraulic cylinder 13 pushes the transition block 24 to move away from the hydraulic cylinder 13. The transition block 24 pushes the slider 29 to move. The slider 29 pushes the gate body 1 to rotate through the guide rod 30, so that the gate bodies 1 close together. During the closing process, the flow of upstream water can generate a thrust on the gate body 1, which helps the gate bodies 1 close together. At the same time, the thrust generated by the flow of upstream water on the gate body 1 continues to act on the gate body 1, which can improve the tightness of the closure of the gate body 1.

[0045] After the gate body 1 is closed, the telescopic component a12 pushes the U-shaped plate 20 away from the gate body 1 to move horizontally (the U-shaped plate 20 will gradually deflect during the horizontal movement). The U-shaped plate 20 drives the bottom end of the conveying section to move horizontally, causing the originally vertical conveying section to become inclined (during this process, the connecting arm 19 will rotate to achieve angle compensation, causing the top position of the conveying section to gradually decrease, ensuring that the U-shaped plate 20 can always move horizontally, and finally the top position of the conveying section decreases to the position of the inclined seat 7). The plate b14 then changes from vertical to inclined; when the upstream water hits the inclined plate... When the inclined plate b14 is in close contact with the gate body, it acts like a ramp, transforming the impact of the water flow into an upward climb along the ramp. This process decomposes a portion of the forward impact force into an upward component along the ramp, greatly reducing the normal pressure perpendicular to the ramp. After the water flow reaches the top of the ramp, it usually falls back and collides, mixes, and tumbles with the water flow that continues to climb, forming complex vortices. This process further consumes its total energy, thus achieving the buffering function of the water flow impact, while not causing high-frequency vibrations to the gate body 1, ensuring the stability of the gate body 1.

[0046] When the upstream water flows towards the gate body 1, it will also carry silt and other impurities to the gate body 1. The conveying unit plate b14 can block most of the silt and impurities in front of the gate body 1, avoiding a large amount of silt accumulation in front of the gate body 1 and significantly reducing the corrosion of the gate body 1 by the silt.

[0047] Before opening the gate, it needs to be leveled. The telescopic component b9 moves the water-blocking block 10 upwards, separating it from the U-shaped sealing frame 11, thus opening the discharge port 101. When the upstream water is discharged through the discharge port 101, the water flow force drives the impeller 17 to rotate. The impeller 17 drives the synchronous pulley c to rotate. The synchronous pulley c drives the synchronous pulley d to rotate via the synchronous toothed belt b. The synchronous pulley d drives the synchronous pulley a23 to rotate. The synchronous pulley a23 drives the synchronous toothed belt a16 to rotate. The synchronous toothed belt a16 drives the plates b14 at various points to rotate synchronously, forming a conveying action. The system enables the upward oblique transport of sludge accumulated on plate b14 (plate c15 is located on plate d31 to prevent the sludge from sliding down during the upward oblique transport process; under the action of water flow, the sludge can continuously move towards plate b14, ensuring that plate b14 fully transports the sludge), thereby realizing the self-cleaning function of sludge in front of the gate. There is no need to degrade the sludge, which significantly improves the sludge cleaning efficiency and prevents sludge blockage, ensuring the stability of sludge cleaning. After the sludge is transported to the top of the gate body 1, it falls into the box 8 for recycling under the guidance of the inclined seat 7.

[0048] When the upstream water level drops to the outlet 101, it indicates that the pressure application to the gate body 1 is complete. At this time, the telescopic component a12 is used again to pull the U-shaped plate 20 closer to the gate body 1, so that the inclined conveying section and plate b14 return to the vertical state (the inclined conveying section and plate b14 occupy a large space, which cannot guarantee that the gate body 1 is fully opened). Then, the hydraulic cylinder 13 is used to pull the adapter block 24 to move in the direction of the hydraulic cylinder 13. The adapter block 24 pulls the slider 29 to move. The slider 29 pulls the gate body 1 to rotate through the guide rod 30, so that the closed gate body 1 can be opened.

[0049] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
