It can intercept rivers or water flows through stable support, effective water retaining, good sealing, reliable connection and fixing, and convenient operation, ensuring the safety and dryness of the water conservancy project construction area. It is used in operations such as dam construction and bridge foundation construction.

[0003] After searching, the Chinese patent with the announcement number CN221441447U discloses a intercepting device for water conservancy construction. The patent records that a driving motor is provided to drive the driving shaft to rotate in both directions, so that the first bevel gear installed at the end of the driving shaft will rotate synchronously with the rotation of the driving shaft, causing the two second bevel gears respectively engaged on the left and right sides of the first bevel gear to rotate synchronously in opposite directions, so that the two shafts respectively installed in the inner walls of the two second bevel gears will also rotate together, causing the two third bevel gears respectively installed at the other ends of the two shafts to rotate. When the two gears are connected, the two fourth bevel gears meshing with each other on one side of the two third bevel gears will also rotate. At this time, the two lifting screw rods installed in the inner walls of the two fourth bevel gears will also rotate together, so that the two lifting threaded sleeves respectively sleeved on the outer walls of the two lifting screw rods will respectively move back and forth in the vertical direction on the outer walls of the two lifting screw rods as the two lifting screw rods rotate, so that the intercepting plate installed between the two lifting sliders will also move up and down inside the protective base, thereby realizing the automatic movement of the intercepting plate, thereby not only improving the stability and safety of the intercepting plate in the up and down movement, but also reducing the labor cost of the technical solution;

[0004] In this solution, when in use, the motor cooperates with the gear threaded rod to operate underwater to realize the lifting and lowering of the intercepting plate. The device uses a large number of gears for operation, and the water contains mud and sand. The mud and sand will increase the wear between the gears, making them easy to be damaged, and the service life is short. In addition, the device is more complicated to maintain, which greatly reduces the work efficiency. In order to solve this technical problem, the utility model proposes a intercepting device for water conservancy construction. Utility Model Content

The mud and sand will increase the wear between the gears, making them easy to be damaged, and the service life is short. In addition, the device is more complicated to maintain, which greatly reduces the work efficiency. In order to solve this technical problem, the utility model proposes a intercepting device for water conservancy construction.

[0008] To achieve the above objectives, the present invention is implemented through the following technical solutions: a diversion device for water conservancy construction, comprising a fixed frame, a motor fixedly connected to the top of the fixed frame, a fixed frame fixedly connected to the top of the fixed frame, a rotating shaft fixedly connected to the output end of the motor, and a pay-off roller fixedly connected to the outer wall of the rotating shaft, a steel wire rope wound around the outer wall of the pay-off roller, a diversion plate fixedly connected to the other end of the steel wire rope, a pair of connecting blocks fixedly connected to one side of the diversion plate, sliding grooves are provided on the inner walls on both sides of the fixed frame, a limiting rod is fixedly connected to the inside of each sliding groove, and the connecting block is slidably connected to the outer wall of the limiting rod.

[0014] (3) Beneficial effects

[0015] The utility model provides a flow intercepting device for water conservancy construction, which has the following beneficial effects:

[0016] (1) The motor is installed on the top of the fixed frame. After starting, it drives the rotating shaft in the fixed frame to rotate. The rotating shaft rotates the wire roller to loosen the wire rope. The wire rope changes direction and reduces friction through the fixed pulley on the bracket. The loosened wire rope drives the intercepting plate to move down. The intercepting plate cooperates with the limit rod in the slide groove through the connecting block to ensure the consistency of the downward movement direction. The intercepting plate is lowered and inserted into the base slot to complete the positioning. This cooperation solves the problem of complex operation and low efficiency of the existing intercepting device. The traditional device operates through the motor and the gear screw. At the same time, the parts will be corroded after long-term operation underwater, and the mud and sand will increase the friction between the gears and thus increase wear. Through their cooperation, a simple structure can reduce loss and extend service life, thereby improving work efficiency.

[0017] (2) When the intercepting plate descends, the water stop strips on both sides slide down along the inner wall of the groove. An inner rod is provided inside the groove, and a wheel is installed on the inner rod. When the water stop strips slide down, they contact the wheel. The original sliding friction between the water stop strips and the groove is converted into rolling friction through the rolling of the wheel. This combination solves the problem of the existing water stop device. In the past, the water stop strips slid in the groove, and the friction was large, which would cause serious wear of the water stop strips and shorten their service life. Frequent replacement of water stop strips increases cost and workload, and the high friction may also affect the smooth movement of the intercepting plate. The change of friction form by the wheel greatly reduces friction resistance, reduces the wear rate of the water stop strips, effectively extends the service life of the water stop strips, and ensures the water stopping effect. At the same time, it also helps the intercepting plate to move more smoothly, and improves the stability of the operation of the entire device. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0024] See also Figure 1-4 , the utility model provides a technical solution:

[0025] Embodiment 1: A diversion device for water conservancy construction, comprising a fixed frame 1, a motor 2 is fixedly connected to the top of the fixed frame 1, a fixed frame 4 is fixedly connected to the top of the fixed frame 1, the output end of the motor 2 is fixedly connected to the rotating shaft 3, and the outer wall of the rotating shaft 3 is fixedly connected to a wire-paying roller 5, a steel wire rope 6 is wound around the outer wall of the wire rope 6, and a diversion plate 9 is fixedly connected to the other end of the steel wire rope 6. A pair of connecting blocks 10 are fixedly connected to one side of the diversion plate 9, and a slide groove 11 is provided on the inner walls of both sides of the fixed frame 1, each slide groove 11 is fixedly connected to a limit rod 12, and the connecting block 10 is slidably connected to the outer wall of the limit rod 12, the top of the fixed frame 1 is fixedly connected to a bracket 7, the top of the bracket 7 is fixedly connected to a fixed pulley 8, and the steel wire rope 6 is wound around the outer wall of the fixed pulley 8, and the bottom of the fixed frame 1 is fixedly connected to a base 17, a slot 18 is provided inside the base 17, and the slot 18 corresponds to the bottom end of the diversion plate 9, and the diversion plate 9 is inserted into the slot 18.

[0026] The motor 2, fixed to the top of the fixed frame 1, is started. Once the motor 2 begins to rotate, it generates power. This power causes the rotating shaft 3, located within the fixed frame 4, to begin rotating. As the rotating shaft 3 rotates, it drives the pay-off roller 5 connected to it to rotate as well. As the pay-off roller 5 rotates, the wire rope 6 wound around it gradually unwinds. As the wire rope 6 unwinds, it passes over the fixed pulley 8 on the bracket 7. The fixed pulley 8 changes the direction of the wire rope 6. At the same time, because the rolling friction between the fixed pulley 8 and the wire rope 6 is much smaller than other forms of friction, it effectively reduces the friction of the wire rope 6 during movement. As the wire rope 6 continues to unwind, it slowly drives the diverter plate 9 downward. As the diverter plate 9 moves downward, the connecting block 10 cooperates with the limiting rod 12, which is positioned within the chute 11, to effectively limit the diverter plate 9. This limiting effect can ensure that the direction of the intercepting plate 9 remains consistent when it moves downward, and there will be no deviation. When the intercepting plate 9 continues to descend, it will eventually be directly inserted into the slot 18 opened on the base 17, thereby completing the positioning. The mutual cooperation between these components achieves the effect of rapid interception and greatly improves work efficiency.

[0027] Example 2: The difference between this example and Example 1 is that, the two side walls of the intercepting plate 9 are fixedly connected with water stop strips 14, the outer surface of the water stop strips 14 is provided with a lubricating coating, each water stop strip 14 is rotatably connected to the inside of an inner rod 16, both ends of the inner rod 16 are fixedly connected to wheels 15, grooves 13 are provided on the inner walls on both sides of the fixed frame 1, the water stop strips 14 are slidably connected in the grooves 13, the wheels 15 correspond to the grooves 13, and the wheels 15 are slidably connected in the grooves 13.

[0028] When the intercepting plate 9 begins to descend, the waterstop strips 14 on both sides of the intercepting plate 9 will move together with the intercepting plate 9, sliding downwards tightly against the inner wall of the groove 13. During this sliding process, an inner rod 16 is provided inside the groove 13, and a wheel 15 is mounted on the inner rod 16. The waterstop strip 14 contacts the wheel 15 when it slides down, and the original sliding friction of the waterstop strip 14 in the groove 13 is converted into rolling friction due to the presence of the wheel 15. This change in friction mode greatly reduces the friction resistance encountered by the waterstop strip 14 during the sliding process. Since the friction resistance is greatly reduced, the wear of the waterstop strip 14 due to friction during long-term use will also be reduced accordingly, thereby effectively extending the service life of the waterstop strip 14, so that it can play a stable water-stopping role for a long time in the interception work.

[0029] Working principle: when the staff uses it, by starting the motor 2 on the top of the fixed frame 1, the rotation of the motor 2 drives the rotating shaft 3 in the fixed frame 4 to rotate, and when the rotating shaft 3 rotates, it drives the wire-paying roller 5 to rotate. When the wire-paying roller 5 rotates, the wire rope 6 is loosened. At the same time, the wire rope 6 changes direction through the fixed pulley 8 on the bracket 7 when it is loosened, and the friction of the wire rope 6 is reduced. At this time, the loosening of the wire rope 6 will slowly drive the intercepting plate 9 to move downward. When the intercepting plate 9 moves downward, it will be limited to the limit rod 12 in the slide groove 11 through the connecting block 10. , thereby ensuring that the direction of the intercepting plate 9 is consistent when it moves downward. During the descent of the intercepting plate 9, the water stop strips 14 on both sides will slide down in accordance with the inner wall of the groove 13. When the groove 13 slides down, the friction will be reduced by the wheels 15 on the internal inner rod 16. The wheels 15 rotate in the groove 13, converting the sliding friction into rolling friction, greatly reducing the friction resistance, thereby extending the service life of the water stop strip 14. When the intercepting plate 9 descends, it will be directly inserted into the slot 18 opened on the base 17 for positioning. Through the cooperation between them, the effect of rapid interception is achieved, and the work efficiency is improved.
