Description

Technical Field

[0001] This invention relates to the field of water conservancy engineering technology, and in particular to a water conservancy steel gate maintenance device. Background Technology

[0002] Hydraulic tunnels are water passageways excavated in mountains or underground. They can be used for irrigation, power generation, water supply, drainage, water conveyance, construction diversion, and navigation. In water conservancy and hydropower projects, steel gates need to be inspected and maintained. Therefore, it is necessary to seal the front side of the steel gate and drain the water remaining in the seal to facilitate the inspection and maintenance of the steel gate.

[0003] Currently, due to the difficulty of excavating water passages in mountains, the excavation space is reduced, resulting in less usable internal space. Vertically lifting water-blocking plates require significant space and cannot be used within mountains, making the sealing structure less suitable. Furthermore, some sealing structures typically use a pivot to rotate the inclined water-blocking plate, or use steel cables to lift or lower it from the bottom. Both of these operating modes rely on a single power source, leading to uneven stress distribution on the water-blocking plate and localized stress concentration, thus shortening the equipment's lifespan. Additionally, problems with one of these operating modes can cause the water-blocking plate to malfunction, making emergency response impossible and increasing the risk of failure. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the prior art by proposing a maintenance device for hydraulic steel gates.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a water conservancy steel gate maintenance device, including a mountain, a tunnel is provided through the mountain, a steel gate body is provided on the inner wall of the tunnel, the tunnel is connected to a water-blocking groove and a placement cavity, and a sealing mechanism, a sealing mechanism, a support mechanism and a cleaning and drying mechanism are provided inside the water-blocking groove and the placement cavity. The sealing mechanism includes two upright blocks fixedly connected to the bottom of the placement cavity, corresponding to the two sides of the water-blocking groove. A second rotating shaft is rotatably connected to the two upright blocks. A water-blocking plate is fixedly connected to the outer wall of the second rotating shaft, corresponding to the inner side of the upright block, and contacts the inclined surface of the inner wall of the water-blocking groove. The bottom end of the water-blocking plate is set as an inclined surface and contacts the bottom of the tunnel. The mechanism also includes a first rotating shaft. A winding drum is fixedly connected to the outer wall of each of the two first rotating shafts. A steel wire rope is wound around each of the two winding drums. The two steel wire ropes are fixedly connected to the water-blocking plate. The first rotating shaft and the second rotating shaft rotate synchronously. The winding steel wire rope generates tension at the bottom of the water-blocking plate. At the same time, the top of the water-blocking plate rotates around the center of the second rotating shaft, reducing the usable space.

[0006] Preferably, the sealing mechanism further includes a fixing block fixedly connected to the top of the placement cavity, a dual-axis motor fixedly passing through the fixing block, the two drive ends of the dual-axis motor and two first rotating shafts fixedly connected respectively, and both first rotating shafts are rotatably connected to the placement cavity.

[0007] Preferably, a first sprocket is fixedly connected to the outer wall of each of the two first rotating shafts corresponding to the outer side of the winding drum, and a second sprocket is fixedly connected to the outer wall of each of the second rotating shafts corresponding to the outer side of the upright block. The two sets of first sprockets and second sprockets are connected by chains.

[0008] Preferably, the sealing mechanism further includes sealing grooves formed on both sides of the water baffle plate near the steel gate body, sealing airbags are fixedly connected to both sides of the inner wall of the two sealing grooves, and sealing columns are fixedly connected to the inclined surfaces of the two water baffles, with the sealing columns being engaged between the sealing airbags for sealing.

[0009] Preferably, the support mechanism includes telescopic grooves formed on both sides of the inner wall of the placement cavity. An electric push rod is fixedly connected to one end of each of the two telescopic grooves that are far apart from each other. A telescopic column is fixedly connected to the telescopic ends of each of the two electric push rods. A support column is fixedly connected to one end of each of the two telescopic columns that are close to each other. A limit plate is fixedly connected below the fixing block on the inner wall of the placement cavity. Sliding grooves are formed on both sides of the inner walls of the two telescopic grooves. Sliding blocks are provided on the inner walls of both sets of sliding grooves. The two sets of sliding blocks and the two telescopic columns are fixedly connected respectively.

[0010] Preferably, the cleaning and drying mechanism includes a diversion cavity B opened inside the baffle plate. Multiple water spray nozzles are provided at the bottom of one end of the baffle plate near the steel gate body. A water pump is fixedly connected to one side of the bottom of the placement cavity. The water pump and the diversion cavity B are connected by a first flexible hose. The water pump inlet is fixedly connected to an inlet pipe that extends to the side of the tunnel away from the baffle plate.

[0011] Preferably, the cleaning and drying mechanism further includes movable slots opened on both sides of the inner wall of the tunnel near the steel gate body, and transverse columns are slidably connected to the inner walls of the two movable slots. A diversion cavity A is opened inside the transverse column, and multiple air outlets are provided at the bottom end of the transverse column and communicate with the diversion cavity A.

[0012] Preferably, a drive motor is fixedly connected to one end of the movable slot on one side, and a threaded rod is fixedly connected to the drive end of the drive motor. The threaded rod is rotatably connected to the movable slot, and the threaded rod is threadedly connected to the transverse column. A hot air blower is fixedly connected to the other side of the bottom of the placement cavity, and the hot air blower and the transverse column are connected by a second flexible hose.

[0013] Compared with the prior art, the present invention has the following beneficial effects: With the designed sealing mechanism, before maintenance, the first and second shafts can be rotated synchronously by a dual-shaft motor, ensuring close contact between the baffle plate and the inclined surface in the baffle channel. During the movement, the baffle plate can be evenly stressed, avoiding localized stress concentration, extending the service life of the equipment. It also allows for dual-system adjustment of the baffle plate, so that if one system fails, the other system continues to operate, preventing the baffle plate from going out of control. This enables emergency response, reduces the risk of failure, and improves safety. Furthermore, this sealing device can be used in mountains with limited internal space, improving the applicability of the sealing structure. The sealing mechanism can block water in the isolation tunnel and make the sealing column get stuck between the sealing airbags. At this time, the sealing airbag is deformed by the pressure of the sealing column, and the sealing airbag and the sealing column are tightly fitted together, thereby improving the sealing performance and preventing water leakage when the steel gate is repaired, thus ensuring the normal progress of the repair. With the support mechanism in place, the waterproof membrane can be adjusted to a horizontal state after maintenance. At this time, the telescopic column can be moved inward synchronously. Through the cooperation of the slide and the slider, the telescopic column can be limited, so that the support column comes to the bottom of the baffle and the bottom of the baffle is in contact with the support column. This reduces the pulling force on the dual-shaft motor and avoids the motor shaft from undergoing slight plastic deformation due to long-term unidirectional pulling force, thereby preventing the motor shaft from bending or breaking. The cleaning and drying mechanism can flush away the silt at the bottom between the baffle and the steel gate during maintenance. After flushing and cleaning, the silt is dried to ensure a clean and tidy maintenance environment and prevent workers from slipping and falling in the silt, thus improving the safety of maintenance.

Detailed Implementation

[0016] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0017] like Figures 1-9 The device shown is a maintenance device for a hydraulic steel gate, comprising a mountain body 1, through which a tunnel 2 is constructed. A steel gate body 3 is installed on the inner wall of the tunnel 2. The tunnel 2 connects to a water-retaining channel 17 and a placement cavity 18. A sealing mechanism, a support mechanism, and a cleaning and drying mechanism are installed inside the water-retaining channel 17 and the placement cavity 18. The sealing mechanism can create a maintenance space during maintenance. The sealing mechanism includes two upright blocks 15 fixedly connected to the bottom of the placement cavity 18 corresponding to both sides of the water-retaining channel 17. A second rotating shaft rotatably passes through the two upright blocks 15. A water-blocking plate 9 is fixedly connected to the inner side of the wall corresponding to the upright block 15, which contacts the inclined surface of the inner wall of the water-blocking channel 17. The bottom end of the water-blocking plate 9 is set as an inclined surface and contacts the bottom of the tunnel 2. It also includes a first rotating shaft 5. A winding drum 10 is fixedly connected to the outer wall of both first rotating shafts 5. A steel wire rope 13 is wound and connected to both winding drums 10. Both steel wire ropes 13 are fixedly connected to the water-blocking plate 9. The first rotating shaft 5 and the second rotating shaft rotate synchronously. The winding steel wire rope 13 generates tension at the bottom of the water-blocking plate 9. At the same time, the top of the water-blocking plate 9 rotates around the center of the second rotating shaft and reduces the space used.

[0018] like Figure 3 , Figure 4 , Figure 6As shown, the sealing mechanism also includes a fixing block 7 fixedly connected to the top of the placement cavity 18. A dual-axis motor 6 is fixedly driven through the fixing block 7. The two drive ends of the dual-axis motor 6 are fixedly connected to two first rotating shafts 5 respectively. Both first rotating shafts 5 are rotatably connected to the placement cavity 18. A first sprocket 12 is fixedly connected to the outer wall of each of the two first rotating shafts corresponding to the outer side of the winding drum 10. A second sprocket 14 is fixedly connected to the outer wall of each second rotating shaft corresponding to the outer side of the upright block 15. The two sets of first sprockets 12 and second sprockets 14 are connected by a chain 4. The first sprockets 12 and second sprockets 14 have the same diameter and therefore the same rotation speed. Therefore, during lifting and lowering, the dual power system avoids jamming and inability to adjust.

[0019] like Figure 8 , Figure 9 As shown, the sealing mechanism also includes sealing grooves 19 on both sides of the water baffle 9 near the steel gate body 3. Sealing airbags 36 are fixedly connected to both sides of the inner wall of each sealing groove 19. Sealing columns 33 are fixedly connected to the inclined surfaces of both water baffles 17. The sealing columns 33 are engaged between the sealing airbags 36 to create a seal. The sealing columns 33 compress the sealing airbags 36, ensuring tight contact and improving sealing performance, preventing leakage during maintenance and ensuring smooth operation.

[0020] like Figure 9 As shown, the support mechanism includes telescopic grooves 34 formed on both sides of the inner wall of the placement cavity 18. Electric push rods 35 are fixedly connected to the ends of the two telescopic grooves 34 that are far apart from each other. Telescopic columns 11 are fixedly connected to the telescopic ends of the two electric push rods 35. Support columns 26 are fixedly connected to the ends of the two telescopic columns 11 that are close to each other. Limiting plates 25 are fixedly connected to the lower part of the inner wall of the placement cavity 18 corresponding to the fixed block 7. Sliding grooves are formed on both sides of the inner wall of the two telescopic grooves. Sliding blocks are provided on the inner walls of both sets of sliding grooves. The two sets of sliding blocks and the two telescopic columns 11 are fixedly connected respectively. The support columns 26 contact the bottom sides of the baffle plate 9 and support the baffle plate 9, reducing the pulling force on the dual-axis motor 6, avoiding minor plastic deformation of the motor shaft, and preventing the motor shaft from bending or breaking.

[0021] like Figure 6 , Figure 8 As shown, the cleaning and drying mechanism includes a diversion chamber B32 inside the baffle plate 9. Multiple water nozzles 30 are installed at the bottom of the baffle plate 9 near the steel gate body 3. A water pump 27 is fixedly connected to one side of the bottom of the placement cavity 18. The water pump 27 and the diversion chamber B32 are connected by a first flexible hose 8. An inlet pipe 31 is fixedly connected to the inlet of the water pump 27 and extends to the side of the tunnel 2 away from the baffle plate 9. Water is drawn from the front of the tunnel 2 through the water pump 27 and the inlet pipe 31, flows into the diversion chamber B32 through the first flexible hose 8, and is dispersed and sprayed out through the water nozzles 30, thereby cleaning the silt.

[0022] like Figure 5 , Figure 7 As shown, the cleaning and drying mechanism also includes movable slots 22 located on both sides of the inner wall of the tunnel 2 near the steel gate body 3. A transverse column 23 is slidably connected to the inner wall of the two movable slots 22. A diversion chamber A28 is opened inside the transverse column 23, and multiple air outlets 29 are passed through the bottom of the transverse column 23 and communicate with the diversion chamber A28. A drive motor 21 is fixedly connected to one end of one movable slot 22, and a threaded rod 20 is fixedly connected to the drive end of the drive motor 21. The threaded rod 20 is rotatably connected to the movable slot 22, and the threaded rod 20 is threadedly connected to the transverse column 23. A hot air blower 16 is fixedly connected to the other side of the bottom of the placement cavity 18, and the hot air blower 16 is connected to the transverse column 23 via a second flexible hose 24. The transverse column 23 slides back and forth within the movable slots 22, thereby changing the drying position to ensure complete drying of the maintenance area. Hot air can be sprayed from different positions through the diversion chamber A28 to quickly complete the drying process. The movable slots 22 are positioned above the water flow plane.

[0023] Working principle: First, before maintenance, start the electric push rods 35 on both sides and retract the telescopic column 11 inward to release the limit on the baffle plate 9. At this time, start the dual-shaft motor 6 to rotate the first shaft 5 on both sides. The first shaft 5 rotates the winding drum 10 to unwind the wire rope 13. The first shaft 5 on both sides rotates the first sprocket 12 synchronously. Due to the presence of the chain 4, it can rotate the second sprocket 14 on both sides, thereby rotating the second shaft. At this time, the baffle plate 9 rotates around the center line of the second shaft and deflects downward to contact the inclined surface on the baffle groove 17, completing the sealing treatment, which facilitates the subsequent maintenance of the steel gate body 3. When sealing, the sealing column 33 will contact the sealing airbag 36 and squeeze the sealing airbag 36 to make it tightly contact the sealing column 33, preventing leakage during maintenance. Then, the steel gate body 3 is opened to drain the water remaining between the steel gate body 3 and the baffle plate 9. At this time, the water pump 27 is started to draw water from the front of the tunnel 2 through the inlet pipe 31 and enter the diversion chamber B32 through the first hose 8. At this time, the water generates a positive pressure effect in the diversion chamber B32, so that the water is sprayed out through the spray nozzle 30. Therefore, the silt between the steel gate body 3 and the baffle plate 9 can be flushed and cleaned. Then, the sealing groove 19 is started to deliver hot air into the diversion chamber A28 through the second hose 24, and a positive pressure is generated in the diversion chamber A28, so that the hot air is sprayed out through the air outlet 29. At the same time, the drive motor 21 is started to rotate the threaded rod 20. The threaded effect of the threaded rod 20 can make the transverse column 23 move back and forth and dry the cleaned area. This ensures that the environment where the staff are located is clean and tidy, avoids slipping and falling during maintenance, and improves the safety of maintenance. After maintenance, the dual-shaft motor 6 is started in reverse, rotating the first shafts 5 on both sides. The first shafts 5, in turn, rotate the winding drum 10, causing the wire rope 13 to be wound up. Simultaneously, through the cooperation of the first sprocket 12, the second sprocket 14, and the chain 4, the baffle 9 rotates around the center line of the second shaft. At this time, the baffle 9 deflects upwards until it contacts the limit plate 25. Therefore, during lifting, the baffle 9 can be evenly stressed, avoiding localized stress concentration, extending the service life of the equipment. Furthermore, the baffle 9 can be adjusted using a dual-system approach, allowing for adjustments in case of system failure. After the effect, another system continues to operate to prevent the baffle plate 9 from going out of control, thereby enabling emergency response, reducing the risk of failure, and improving safety. At this time, the reverse start electric push rod 35 pushes the telescopic column 11 to move inward. Due to the cooperation of the slider and the slide groove, the telescopic column 11 can be limited. At this time, the support column 26 is on both sides below the baffle plate 9. Then, the dual-axis motor 6 is started to make the baffle plate 9 contact the support column 26, thereby reducing the pulling force on the dual-axis motor 6 and avoiding the motor shaft from undergoing slight plastic deformation due to long-term unidirectional pulling force, thereby preventing the motor shaft from bending or breaking.
