Description

Technical Field

[0001] This invention relates to the field of hydraulic gates, specifically a hydraulic control gate. Background Technology

[0002] Gates are control facilities used to close and open water discharge channels. They are an important component of hydraulic structures, used to intercept water flow, control water levels, regulate flow, and discharge sediment and floating debris. With the continuous development of science and technology, hydraulic gate equipment has been widely used due to its unique advantages. Closing gates can block floods, tides, or raise upstream water levels to meet the water needs of irrigation, power generation, navigation, aquaculture, environmental protection, and other social uses. Opening gates can discharge floodwaters, drain waterlogged areas, flush sand, or regulate downstream water flow. A gate mainly consists of three parts: the main moving part, the embedded part, and the opening and closing equipment. Generally, in hydraulic engineering, vertical gates are driven by a power source and steel cables to complete the lifting and lowering action. The height and position of the gate are controlled according to changes in the actual water level to regulate and change the flow of the hydraulic project. Due to the large overall mass of hydraulic gates, the steel cables are prone to breakage during the height adjustment process. In this case, the hydraulic gate will descend rapidly under its own weight, making direct hard contact with the gate bottom plate, which will not only damage the gate but also destroy the gate bottom plate.

[0003] A search revealed that Chinese patent CN116224881A discloses an emergency braking control method for hydraulic gates. Although the control components can perform braking control in real time, they cannot change the gate's size. When the gate's size does not match the dam's reserved size after pouring, the gate cannot be installed or used. This not only prolongs the gate's construction period but also increases costs. Furthermore, the gate has too many electrical components, which not only complicates the wiring but also makes the electrical components prone to damage after use, shortening the gate's service life and further increasing costs.

A gate valve is installed on the main gate plate.

[0008] As a further aspect of the present invention: the top wall of the fixed column is fixedly sleeved with a first limiting tube and a second limiting tube.

[0009] As a further aspect of the present invention: both the first limiting tube and the second limiting tube are slidably sleeved with the first rotating shaft and the locking strip, and the gap between the first limiting tube and the second limiting tube spirals around the central axis of the first rotating shaft once, and the gap between the first limiting tube and the second limiting tube is connected end to end, and the sliding column is slidably sleeved with the gap.

[0010] As a further embodiment of the present invention: one end of an electric push rod is mounted on the bottom surface of the first limiting tube, and a sliding ring is fixedly connected to the other end of the electric push rod. A pin is fixedly connected to the bottom surface of the sliding ring. One end of a second rotating shaft is rotatably connected to the bottom surface of the first rotating shaft. A second driving helical gear is fixedly sleeved on the other end of the second rotating shaft. A second driven helical gear is meshed with the outer surface of the second driving helical gear. One end of a first transmission rod is fixedly connected to the central axis of the second driven helical gear. The other end of the first transmission rod is fixedly connected to the second driving gear. A second driven gear is meshed with the outer surface of the second driving gear. One end of a second transmission rod is fixedly sleeved on the central axis of the second driven gear. A positioning block is rotatably sleeved on the other end of the second transmission rod. A third driving gear is fixedly sleeved on the outer surface of the other end of the second transmission rod. A third driven gear is meshed with the outer surface of the third driving gear. A rotating column is fixedly sleeved on the inner surface of the third driven gear. A screw is meshed with the central axis of the rotating column. Both ends of the screw are fixedly connected to the opposite surface of the extension gate.

[0011] As a further embodiment of the present invention: the inner surface of the sliding ring is fitted and sleeved with the outer surface of the card strip, and multiple electric push rods and inserts are provided, and the electric push rods and inserts are evenly distributed about the central axis of the sliding ring.

[0012] As a further embodiment of the present invention: the insert is engaged with the top surface of the second active helical gear, the second active helical gear is rotatably connected to the bottom surface of the cavity, and both the first transmission rod and the second transmission rod are rotatably connected to the end face of the cavity.

[0013] As a further embodiment of the present invention: the positioning block is fixedly connected to the side wall of the cavity, the third driving gear is rotatably sleeved with the positioning block, the rotating column is hinged to the positioning block, and the positioning block extends to the area between the opposite surfaces of the extension gate.

[0014] Compared with the prior art, the beneficial effects of the present invention, using the above technical solution, are as follows:

[0015] 1. In this invention, an electric push rod pushes the sliding ring down, causing the insert on the sliding ring to insert into the second active helical gear, so that the second active helical gear and the sliding ring are relatively stationary. During the rotation of the first rotating shaft, the first rotating shaft drives the sliding ring to rotate through the retaining strip, thereby causing the second active helical gear to rotate around the second rotating shaft, and causing the second driven helical gear, which is meshed with the second active helical gear, to rotate. This causes the first transmission rod on the second driven helical gear to rotate via the second driving gear, which in turn causes the second transmission rod on the second driven gear to rotate via the third driving gear. This, in turn, causes the third driven gear to rotate the rotating column. Meanwhile, the screw, which meshes with the rotating column, is limited by the extension gate and cannot rotate. The rotation of the rotating column causes the screw to translate, which in turn causes the extension gate to translate, indirectly extending the main gate. This creates a slanted lock, allowing the hydraulic control gate to be adapted to various dam sizes for installation and use, eliminating the need for rework and recasting. This not only shortens the construction period but also saves costs.

[0016] 2. In this invention, the rotation of the first rotating shaft drives the sliding column to move. The sliding column is slidably sleeved with the gap between the first and second limiting tubes. Since the gap between the first and second limiting tubes spirals around the central axis of the first rotating shaft, the sliding column gradually rises along the gap as it moves, thereby raising the first rotating shaft and the lifting gear, until the sliding column moves to half the height of the gap. At this point, the lifting gear completely separates from the transmission gear and meshes with the internal gear ring. At this time, the gate valve is opened until the water level on both sides of the hydraulic control gate shifts horizontally. As the first... As the shaft rotates further, the lifting gear rises while simultaneously causing the internal gear ring to rotate in the opposite direction. This causes the pull rod on the internal gear ring to push the connecting plate, opening the main gate plate around the fixed column until the sliding column moves to the top of the gap. Once the gap is closed, the sliding column falls back to its initial state. By repeating the above operation, the opening and closing of the hydraulic control gate can be completed without changing the direction of the water flow to change the direction of the hydraulic motor. This not only reduces the investment in water conveyance components but also avoids energy loss when the hydraulic motor reverses, thus reducing costs while ensuring sufficient power.

[0017] 3. The hydraulic control gate of the present invention does not require load increase after opening, thereby avoiding sudden drop of the hydraulic control gate and thus eliminating the need for emergency braking. At the same time, the size change, opening and closing of the hydraulic control gate can all be completed by hydraulic motor, thereby reducing the use of electrical components, avoiding the complexity of electrical component wiring, extending the service life of the hydraulic control gate, and further reducing cost consumption.

[0028] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding the present invention, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0029] Example 1

[0030] Please see Figures 1-7 and Figure 9 This invention provides a technical solution: a hydraulic control gate, comprising a fixed column 1, a main gate plate 2 hinged to one side of the side wall of the fixed column 1, a first telescopic plate 3 fixedly connected to the other side of the main gate plate 2, an extension gate plate 4 slidably sleeved on the outer surface of the first telescopic plate 3, a second telescopic plate fixedly connected to one side of the side wall of the extension gate plate 4, the other side of the second telescopic plate slidably sleeved with the main gate plate 2, a cavity 5 formed in the side wall of the main gate plate 2, a hydraulic motor 6 mounted on the top surface of the fixed column 1, a first driving gear 7 fixedly connected to the output end of the hydraulic motor 6, a first driven gear 8 meshing with the outer surface of the first driving gear 7, a transmission shaft 9 fixedly connected to one end of the central axis of the first driven gear 8, and a first driving helical gear 10 fixedly sleeved on the other end of the transmission shaft 9. The outer surface of the driving helical gear 10 is meshed with a first driven helical gear 11. A first rotating shaft 13 is slidably sleeved on the central axis of the first driven helical gear 11. A retaining strip 12 is fixedly connected to the outer surface of the first rotating shaft 13. The outer surface of the retaining strip 12 is fitted and sleeved with the first driven helical gear 11. A sliding column 14 is fixedly connected to the bottom end of the first rotating shaft 13. A lifting gear 15 is fixedly sleeved at the top end of the first rotating shaft 13. A transmission gear 16 is meshed with the outer surface of the lifting gear 15. One end of a rotating frame 17 is fixedly sleeved on the central axis of the transmission gear 16. An internal gear ring 18 is fixedly connected to the other end of the rotating frame 17. One end of a pull rod 19 is rotatably connected to the bottom surface of the internal gear ring 18. A connecting plate 20 is rotatably connected to the other end of the pull rod 19. The connecting plate 20 is fixedly connected to the top surface of the main gate plate 2.

[0031] Please see Figure 1 and Figure 3 The top view of the extended gate plate 4 is U-shaped. The transmission shaft 9 is rotatably connected to the top of the fixed column 1. The first driven helical gear 11 is rotatably connected to the top surface of the fixed column 1. The rotating frame 17 is rotatably connected to the top of the fixed column 1.

[0032] Please see Figure 6 Multiple locking strips 12 are provided, and the multiple locking strips 12 are evenly distributed about the central axis of the first rotating shaft 13. The bottom end of the first rotating shaft 13 extends into the cavity 5. A sealing strip is provided between the extension gate 4 and the main gate 2. A gate valve is installed on the main gate 2.

[0033] Specifically, during the closing process of the hydraulic control valve, the hydraulic motor 6 is activated, causing the hydraulic motor 6 to drive the first driven gear 8, which meshes with it, to rotate via the first driving gear 7. This causes the transmission shaft 9 on the first driven gear 8 to drive the first driven helical gear 11, which in turn drives the locking strip 12, which is fitted with it, to rotate. This causes the first rotating shaft 13 on the locking strip 12 to rotate, which in turn causes the lifting gear 15 on the first rotating shaft 13 to drive the transmission gear 16 to rotate. This causes the rotating frame 17 on the transmission gear 16 to drive the internal gear ring 18 to rotate, and the internal gear ring 18 to pull the connecting plate 2 via the pull rod 19. The main gate 2 and the main gate plate 2 rotate around the fixed column 1 until the extended gate plate 4 on the main gate plate 2 contacts each other, and the rotation angle of the main gate plate 2 is less than 90°, forming a slanted lock. At this time, the hydraulic control gate closes and completes the water cut-off. At the same time, the hydraulic control gate does not need to be increased in load after it is opened, thus avoiding the sudden drop of the hydraulic control gate and thus eliminating the need for emergency braking. In addition, the size change, opening and closing of the hydraulic control gate can all be completed by the hydraulic motor 6, which reduces the use of electrical components, avoids the complexity of electrical component wiring, extends the service life of the hydraulic control gate, and further reduces the cost.

[0034] Example 2

[0035] Please see Figures 5-7 The present invention provides a technical solution: a water conservancy control gate, wherein a first limiting pipe 21 and a second limiting pipe 22 are fixedly sleeved on the top wall of the fixed column 1.

[0036] Please see Figure 6 The first limiting tube 21 and the second limiting tube 22 are both slidably sleeved with the first rotating shaft 13 and the locking strip 12, and the gap between the first limiting tube 21 and the second limiting tube 22 spirals around the central axis of the first rotating shaft 13 once, and the gap between the first limiting tube 21 and the second limiting tube 22 is connected end to end, and the sliding column 14 is slidably sleeved with the gap.

[0037] Specifically, during the opening of the hydraulic control valve, the rotation of the first rotating shaft 13 drives the sliding column 14 to move. The sliding column 14 is slidably sleeved with the gap between the first limiting tube 21 and the second limiting tube 22. Since the gap between the first limiting tube 21 and the second limiting tube 22 spirals around the central axis of the first rotating shaft 13, as the sliding column 14 moves, it gradually rises along the gap, thereby raising the first rotating shaft 13 and the lifting gear 15, until the sliding column 14 moves to half the height of the gap. At this time, the lifting gear 15 completely separates from the transmission gear 16 and meshes with the internal gear ring 18. At this point, the gate valve is opened until both sides of the hydraulic control gate are open. The water level shifts horizontally, and as the first rotating shaft 13 rotates further, the lifting gear 15 rises while driving the internal gear ring 18 to rotate in the opposite direction. This causes the pull rod 19 on the internal gear ring 18 to push the connecting plate 20, causing the main gate plate 2 to open around the fixed column 1 until the sliding column 14 moves to the top of the gap. When the two ends of the gap are connected, the sliding column 14 will fall back to its initial state. By repeating the above operation, the opening and closing of the hydraulic control gate can be completed without changing the direction of the water flow to change the direction of the hydraulic motor 6. This not only reduces the investment in water conveyance devices, but also avoids the energy loss when the hydraulic motor 6 reverses, thus reducing the cost investment and ensuring sufficient power.

[0038] Example 3

[0039] Please see Figure 4 , Figure 5 , Figure 7 and Figure 8 This invention provides a technical solution: a hydraulic control gate, wherein one end of an electric push rod 23 is mounted on the bottom surface of a first limiting tube 21, and the other end of the electric push rod 23 is fixedly connected to a sliding ring 24. A pin 25 is fixedly connected to the bottom surface of the sliding ring 24. One end of a second rotating shaft 26 is rotatably connected to the bottom surface of a first rotating shaft 13. A second driving helical gear 27 is fixedly sleeved on the other end of the second rotating shaft 26. A second driven helical gear 28 is meshed with the outer surface of the second driving helical gear 27. One end of a first transmission rod 29 is fixedly connected to the central axis of the second driven helical gear 28, and the other end of the first transmission rod 29 is fixedly connected to a second... The outer surface of the second driving gear 30 is meshed with a second driven gear 31. One end of the second transmission rod 32 is fixedly sleeved on the central axis of the second driven gear 31. The other end of the second transmission rod 32 is rotatably sleeved with a positioning block 33. The outer surface of the other end of the second transmission rod 32 is fixedly sleeved with a third driving gear 34. The outer surface of the third driving gear 34 is meshed with a third driven gear 35. The inner surface of the third driven gear 35 is fixedly sleeved with a rotating column 36. The central axis of the rotating column 36 is meshed with a screw 37. Both ends of the screw 37 are fixedly connected to the opposite surface of the extension gate 4.

[0040] Please see Figure 5The inner surface of the sliding ring 24 is fitted and sleeved with the outer surface of the clip 12. Multiple electric push rods 23 and inserts 25 are provided, and the electric push rods 23 and inserts 25 are evenly distributed about the central axis of the sliding ring 24.

[0041] Please see Figure 2 , Figure 4 , Figure 5 and Figure 9 The insert 25 is engaged with the top surface of the second active helical gear 27, the second active helical gear 27 is rotatably connected to the bottom surface of the cavity 5, and the first transmission rod 29 and the second transmission rod 32 are both rotatably connected to the end surface of the cavity 5.

[0042] Please see Figure 2 and Figure 8 The positioning block 33 is fixedly connected to the side wall of the cavity 5, the third drive gear 34 is rotatably sleeved with the positioning block 33, the rotating column 36 is hinged with the positioning block 33, and the positioning block 33 extends to the area between the opposite surfaces of the extension gate 4.

[0043] Specifically, during the adjustment of the size of the hydraulic control valve, if the size of the hydraulic control gate does not conform to the reserved size of the dam, i.e., it cannot form a slanted lock, then the electric push rod 23 on the first limit tube 21 is activated, causing the electric push rod 23 to push the sliding ring 24 down, so that the insert pin 25 on the sliding ring 24 is inserted into the second active helical gear 27, so that the second active helical gear 27 and the sliding ring 24 are relatively stationary. During the rotation of the first rotating shaft 13, the first rotating shaft 13 drives the sliding ring 24 to rotate through the retaining strip 12, thereby causing the second active helical gear 27 to rotate around the second rotating shaft 26, causing the second driven helical gear 28, which is meshed with the second active helical gear 27, to rotate. This causes the first transmission rod 29 on the second driven helical gear 28 to drive the second driven gear 31 to rotate via the second driving gear 30. The second transmission rod 32 on the second driven gear 31 then drives the third driven gear 35 to rotate via the third driving gear 34. This causes the third driven gear 35 to drive the rotating column 36 to rotate. The screw 37, which meshes with the rotating column 36, is limited by the extension gate plate 4 and cannot rotate. The rotation of the rotating column 36 causes the screw 37 to translate, which in turn causes the extension gate plate 4 to translate, indirectly extending the main gate plate 2. This forms a slanted lock, allowing the hydraulic control gate to be adapted to various dam sizes for installation and use. This eliminates the need for rework and recasting of the gate, shortening the construction cycle and saving costs.

[0044] The working principle and usage process of this invention: When a hydraulic control gate needs to be installed, the fixed column 1 is firmly installed on the dam. Then, the hydraulic motor 6 is started, which drives the first driven gear 8, which is meshed with it, to rotate through the first driving gear 7. The transmission shaft 9 on the first driven gear 8 drives the first driven helical gear 11 to rotate through the first driving helical gear 10. This causes the first driven helical gear 11 to drive the locking strip 12, which is fitted with it, to rotate. The first rotating shaft 13 on the locking strip 12 rotates, which in turn causes the lifting gear 15 on the first rotating shaft 13 to drive the transmission gear 16 to rotate. The rotating frame 17 on the transmission gear 16 drives the internal gear ring 18 to rotate. The internal gear ring 18 pulls the connecting plate 20 and the main gate plate 2 around the fixed column 1 through the pull rod 19 until the extension gate plate 4 on the main gate plate 2 contacts each other and the rotation angle of the main gate plate 2 is less than 90°, forming a slanted lock. At this time, the hydraulic control gate is closed, and the water is cut off.

[0045] If the size of the hydraulic control gate does not meet the reserved size of the dam, i.e., it cannot form a slanted lock, then the electric push rod 23 on the first limit tube 21 is activated, causing the electric push rod 23 to push the sliding ring 24 down, so that the insert pin 25 on the sliding ring 24 is inserted into the second active helical gear 27, so that the second active helical gear 27 and the sliding ring 24 are relatively stationary. During the rotation of the first rotating shaft 13, the first rotating shaft 13 drives the sliding ring 24 to rotate through the locking strip 12, thereby causing the second active helical gear 27 to rotate around the second rotating shaft 26, and causing the second driven helical gear 28, which is meshed with the second active helical gear 27, to rotate. This causes the first transmission rod 29 on the second driven helical gear 28 to drive the second driven gear 31 to rotate via the second driving gear 30. The second transmission rod 32 on the second driven gear 31 then drives the third driven gear 35 to rotate via the third driving gear 34. This causes the third driven gear 35 to drive the rotating column 36 to rotate. The screw 37, which is meshed with the rotating column 36, is limited by the extension gate plate 4 and cannot rotate. This causes the rotation of the rotating column 36 to drive the screw 37 to translate, which in turn causes the screw 37 to drive the extension gate plate 4 to translate, thereby indirectly extending the main gate plate 2. This forms a slanted lock, which changes the size of the hydraulic control gate. This allows the hydraulic control gate to be installed and used in dams of various sizes without the need for rework and recasting. This not only shortens the construction cycle of the gate but also saves costs.

[0046] During the rotation of the first rotating shaft 13, the rotation of the first rotating shaft 13 will drive the sliding column 14 to move. The sliding column 14 is slidably sleeved with the gap between the first limiting tube 21 and the second limiting tube 22. Since the gap between the first limiting tube 21 and the second limiting tube 22 spirals around the central axis of the first rotating shaft 13, as the sliding column 14 moves, the sliding column 14 will gradually rise along the gap, thereby raising the first rotating shaft 13 and the lifting gear 15, until the sliding column 14 moves to half the height of the gap. At this time, the lifting gear 15 completely separates from the transmission gear 16 and meshes with the internal gear ring 18. At this time, the gate valve is opened until both sides of the hydraulic control gate are opened. The water level shifts horizontally, and as the first rotating shaft 13 rotates further, the lifting gear 15 lifts up and drives the internal gear ring 18 to rotate in the opposite direction, causing the pull rod 19 on the internal gear ring 18 to push the connecting plate 20, so that the main gate plate 2 opens around the fixed column 1 until the sliding column 14 moves to the top of the gap, and the beginning and end of the gap are connected, then the sliding column 14 will fall down and return to the initial state. By repeating the above operation, the opening and closing of the hydraulic control gate can be completed without changing the direction of the water flow to change the direction of the hydraulic motor 6. This not only reduces the investment in water conveyance devices, but also avoids the energy loss when the hydraulic motor 6 reverses, which not only reduces the cost investment, but also ensures sufficient power.

[0047] In the above process, the hydraulic control gate does not need to be raised after it is opened, thus avoiding the sudden drop of the hydraulic control gate and therefore eliminating the need for emergency braking. At the same time, the size change, opening and closing of the hydraulic control gate can all be completed by the hydraulic motor 6, which reduces the use of electrical components, avoids the complexity of electrical component wiring, extends the service life of the hydraulic control gate, and further reduces the cost of operation.

[0048] It needs to be further explained that when the size of the above-mentioned water control gate does not meet the reserved size of the dam and the size of the water control gate needs to be adjusted, the extension gate plate 4 can be smoothly formed into a slanted lock after translation, thus completing the adjustment of the size of the water control gate. There is no need to return the extension gate plate 4. Since the water control gate needs to be used for a long time after installation, it does not need to be transferred to a dam of other sizes. The translation of the extension gate plate 4 is a one-time process, so the unidirectional rotation of the first rotating shaft 13 has no effect.

[0049] Simultaneously, the insert 25 engages with the top surface of the second active helical gear 27, indicating that the second active helical gear 27 has a corresponding locking hole for the insert 25. If the main gate 2 is in its initial state, the sliding pin 14 is in its initial position, thus the first rotating shaft 13, sliding ring 24, and insert 25 are all in their initial positions. When the electric push rod 23 is activated to push the sliding ring 24, the insert 25 can be precisely inserted into the locking hole on the second active helical gear 27. If the main gate 2 is rotating, and the descent of the insert 25 cannot precisely engage with the locking hole, due to… As the first rotating shaft 13 continues to rotate, the sliding ring 24 will continuously drive the insert 25 to rotate. When the electric push rod 23 pushes the insert 25 to contact the top surface of the second driving helical gear 27, the electric push rod 23 continuously applies pressure to the insert 25. At the same time, the insert 25 slides and rotates on the top surface of the second driving helical gear 27. Therefore, the insert 25 will always contact the locking hole. When the central axis of the insert 25 coincides with the central axis of the locking hole, the insert 25 will be inserted into the locking hole due to the pressure, thus completing the insertion and relative static connection between the second driving helical gear 27 and the sliding ring 24.
