Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, and more particularly to a lifting gate for water conservancy projects. Background Art

[0002] In existing technologies, in water conservancy projects, lifting gates are key equipment for regulating water levels and flow rates. However, in existing technologies, it is inconvenient to fix the valve plate after it rises to a specified position. This may involve using bolts or other methods to fix it, but the stability effect of these methods is not ideal, and it is easy to cause the valve plate to shake or even fall during the lifting process. This unstable situation not only affects the normal operation of the gate, but also poses a threat to the safety of the water conservancy project.

[0003] With the development of automated control technology, the safety and reliability of valve plate fixing devices are receiving increasing attention. While some existing methods attempt to address this issue, such as using bolts, these methods often fail to achieve the desired stability. This not only poses a risk to the normal operation of the equipment, but also, in certain high-precision applications, even the slightest movement of the valve plate can lead to unpredictable consequences.

[0015] (3) Beneficial effects

[0016] Compared with the prior art, the present invention provides a hydraulic engineering lifting gate with the following features:

[0017] Beneficial effects:

[0018] 1. The lifting mechanism realizes precise lifting and lowering control of the valve plate through the cooperation of the valve plate, transmission block, screw, gear box, connecting rod and handle. The valve plate is slidably installed in the outer frame, and the rotary motion is converted into linear motion of the valve plate through the threaded connection of the transmission block and the screw. The setting of the gear box and connecting rod enables the operator to easily rotate the gear box through the handle, thereby driving the lifting and lowering of the screw and valve plate. The beneficial effects of this design include: easy operation, improved lifting accuracy and efficiency, reduced need for manual operation, and enhanced degree of automation of the system.

[0019] 2. The fixing mechanism includes a stop block, a fixing rod, a fixing sleeve, a fixing plate, a movable hole, an annular rod, a push plate, a clamping block and a clamping slot. These components together ensure the stability and safety of the valve plate during the lifting process. The stop blocks are distributed on both sides of the outer frame and are aligned and abutted against the fixing plate to provide additional support. The setting of the fixing rod and the fixing sleeve ensures that the relative position of the valve plate and the outer frame is fixed, while the sliding connection between the movable hole and the annular rod allows the annular rod to slide freely in the movable hole. The push of the push plate and the cooperation of the clamping block and the clamping slot, through the elastic force of the compression spring and the pressure spring, enable the clamping block to be stably clamped on the fixing rod, thereby fixing the position of the annular rod. The beneficial effects of this design include: improving the stability of the system, reducing the shaking of the valve plate during the lifting process, enhancing the fixing effect, and ensuring the reliability of long-term operation.

[0020] 3. The locking mechanism includes a lock groove, a lock sleeve, a vertical rod, a lock hole, a rotating sleeve and a lock rod, which provides a fast and reliable locking mechanism for the entire lifting gate. The sliding lock sleeve makes its top surface abut against the lock groove on the annular rod, limiting the position of the annular rod. By rotating the rotating sleeve, the lock rod is driven to rotate and inserted into the lock hole on the vertical rod, thereby locking the position of the lock sleeve and locking the annular rod. The beneficial effects of this design include: fast locking and unlocking, improved operational convenience, enhanced system safety, prevention of accidental movement of the valve plate when the water level changes, and ensuring the safe operation of the water conservancy project.

[0030] See also Figure 1-Figure 5 A water conservancy project lifting gate includes an outer frame 1, on which a lifting mechanism is provided. The lifting mechanism includes a valve plate 2, a transmission block 3, a screw 4, a gear box 5, a connecting rod 6 and a turning handle 7. The valve plate 2 is slidably mounted in the outer frame 1.

The turning handle 7 is mounted on the gear box 5. A fixing mechanism is provided on both sides of the valve plate 2. The fixing mechanism includes a stop block 8, fixed rod 9, fixed sleeve 10, fixed plate 11, movable hole 12, annular rod 13, push plate 14, block 15 and slot 16, the block 8 is provided with multiple groups distributed on both sides of the outer frame 1, the fixed rod 9 is fixed on both sides of the valve plate 2, the fixed sleeve 10 is arranged on the fixed rod 9, the fixed plate 11 is installed at the bottom end of the fixed sleeve 10, the movable hole 12 is arranged on the outer wall of the fixed sleeve 10, the annular rod 13 is slidably installed in the movable hole 12, the push plate 14 is arranged in the fixed sleeve 10, the block 15 is installed at the bottom end of the annular rod 13, and the slot 16 is provided on the outer wall of the fixed rod 9.

[0031] Slide grooves 17 are provided on both sides of the outer frame 1, and the two sets of fixed rods 9 slide in the slide grooves 17. The slide grooves 17 provided on both sides of the outer frame 1 allow the fixed rods 9 to slide therein, so that the fixed rods 9 can move with the lifting and lowering of the valve plate while maintaining the relative position with the valve plate unchanged.

[0032] The movable hole 12 is provided with multiple groups and a positioning groove 18 is opened on the inner side. The annular rod 13 is provided with multiple groups and a positioning strip 19 is provided on the outer wall. The multiple groups of positioning strips 19 are slidingly connected with the multiple groups of positioning grooves 18. The positioning grooves 18 on the inner side of the movable hole 12 are slidingly connected with the positioning strips 19 on the outer wall of the annular rod 13. This design ensures the precise position of the annular rod 13 in the movable hole 12 and improves the stability of the valve plate when it is raised and lowered.

[0033] A compression spring 20 is connected between the push plate 14 and the top inner end of the fixed sleeve 10. The compression spring 20 between the push plate 14 and the top inner end of the fixed sleeve 10 provides a restoring force, so that the push plate 14 can apply stable pressure to the annular rod 13 during the valve plate lifting process.

[0034] Ball blocks 21 are installed on the top ends of the multiple groups of annular rods 13 .

[0035] Compression springs 22 are connected between multiple groups of ball blocks 21 and the inner wall of the fixed sleeve 10. The compression springs 22 between the ball blocks 21 at the top of the annular rod 13 and the inner wall of the fixed sleeve 10 further enhance the stability of the system and ensure the smooth sliding of the annular rod 13 during the lifting process.

[0036] In this embodiment, when it is necessary to adjust the water level or flow, the operator rotates the gear box 5 by turning the handle 7, and the gear in the gear box 5 meshes with the gear on the screw 4, causing the screw 4 to rotate. The rotation of the screw 4 is transmitted to the valve plate 2 through the transmission block 3, causing the valve plate 2 to move up and down along the inner wall of the outer frame 1, thereby realizing the lifting and lowering of the valve plate 2. When the valve plate 2 is lifted or lowered, the fixing rod 9 slides in the slide groove 17 of the outer frame 1 to maintain its relative position with the valve plate 2. The abutments 8 are distributed on both sides of the outer frame 1. When the valve plate 2 moves to a suitable position, the fixing plate 11 is aligned and abutted with the multiple groups of abutments 8, and the fixing sleeve 10 is sleeved on the fixing rod 9. When the fixing rod When the top of 9 contacts the push plate 14, it pushes it and squeezes the compression spring 20. The push plate 14 pushes the multiple sets of ball blocks 21 to make the multiple sets of arc rods slide along the movable hole 12, so that the arc rods push the bottom end of the card block 15 to be clamped in the card groove 16 set on the outer wall of the fixed rod 9. When the ball block 21 moves, it squeezes the compression spring 22, and then the multiple sets of arc rods are locked by the locking mechanism, so that the multiple sets of card blocks 15 fix the fixed rod 9. While the locking mechanism fixes the arc rod, the elastic force of the compression spring 20 and the multiple sets of compression springs 22 applies a reverse force to the fixed rod 9, thereby making the clamping of the multiple sets of card blocks 15 to the fixed rod 9 more stable.

[0037] See also Figure 5 As an implementation method of the locking mechanism: a locking mechanism is provided on the outer wall of the fixed sleeve 10, and the locking mechanism includes a locking groove 23, a locking sleeve 24, a vertical rod 25, a locking hole 26, a rotating sleeve 27 and a locking rod 28. The locking groove 23 is provided on the outer wall of multiple groups of annular rods 13, the locking sleeve 24 is slidably installed on the outer wall of the fixed sleeve 10, the vertical rod 25 is provided with multiple groups installed at the bottom end of the locking sleeve 24, the locking hole 26 is provided with multiple groups distributed at the bottom ends of multiple groups of vertical rods 25, the rotating sleeve 27 is rotatably installed on the outer wall of the fixed sleeve 10, and the locking rod 28 is provided with multiple groups installed on the outer wall of the rotating sleeve 27.

[0038] The multiple lock rods 28 are all arranged in an arc shape. The multiple lock holes 26 are adapted to the multiple lock rods 28. This design enables the lock rods 28 to be inserted into the lock holes 26, thereby fixing the position of the lock sleeve 24 and achieving locking of the annular rod 13.

[0039] More specifically, the sliding locking sleeve 24 makes its top surface abut against the locking groove 23 provided on the multiple groups of arc rods, thereby limiting the position of the multiple groups of arc rods, and then the rotating sleeve 27 is rotated to drive the multiple groups of locking rods 28 to rotate, so that the multiple groups of locking rods 28 are inserted into the locking holes 26 provided on the multiple groups of vertical rods 25, thereby locking the position of the locking sleeve 24, fixing the position of the locking sleeve 24 and locking the multiple groups of arc rods.

[0040] In summary, when the entire device is in use or running: when it is necessary to adjust the water level or flow, the operator rotates the gear box 5 by turning the handle 7, and the gear in the gear box 5 meshes with the gear on the screw 4, causing the screw 4 to rotate. The rotation of the screw 4 is transmitted to the valve plate 2 through the transmission block 3, causing the valve plate 2 to move up and down along the inner wall of the outer frame 1, thereby realizing the lifting and lowering of the valve plate 2. When the valve plate 2 is lifted or lowered, the fixing rod 9 slides in the slide groove 17 of the outer frame 1 to maintain its relative position with the valve plate 2. The abutments 8 are distributed on both sides of the outer frame 1. When the valve plate 2 moves to a suitable position, the fixing plate 11 is aligned and abutted with the multiple groups of abutments 8, and the fixing sleeve 10 is sleeved on the fixing rod 9. When the top of the fixing rod 9 contacts the push plate 14, it pushes it and squeezes the compression spring 20. The push plate 14 pushes the multiple sets of ball blocks 21 to make the multiple sets of arc rods slide along the movable hole 12, so that the arc rod pushes the bottom end of the card block 15 to be clamped in the card groove 16 set on the outer wall of the fixing rod 9. When the ball block 21 moves, it squeezes the compression spring 22, and then the multiple sets of arc rods are locked by the locking mechanism, so that the multiple sets of card blocks 15 fix the fixing rod 9. While the locking mechanism fixes the arc rod, the elastic force of the compression spring 20 and the multiple sets of compression springs 22 exerts a reverse force on the fixing rod 9, thereby making the clamping of the multiple sets of card blocks 15 to the fixing rod 9 more stable.

[0041] The sliding locking sleeve 24 makes its top surface abut against the locking groove 23 provided on the multiple groups of arc rods, thereby limiting the position of the multiple groups of arc rods, and then rotating the rotating sleeve 27 drives the multiple groups of locking rods 28 to rotate, so that the multiple groups of locking rods 28 are inserted into the locking holes 26 provided on the multiple groups of vertical rods 25, thereby locking the position of the locking sleeve 24, fixing the position of the locking sleeve 24 and locking the multiple groups of arc rods.

[0042] In all the schemes mentioned above, the connection between the two components can be selected according to actual conditions by welding, bolt and nut connection, bolt or screw connection or other well-known connection methods, which will not be listed here one by one. In the above, all fixed connections are preferably welded. Although the embodiments of the present invention have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
