Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy equipment, in particular to a water retaining structure of a gate of a large-scale water conservancy project. Background Art

[0002] A sluice is a multifunctional low-head hydraulic structure, the core of which is to use gates to regulate water flow. It is often cleverly arranged on the banks of rivers, canals, reservoirs, oceans, and lakes, playing an indispensable role. When the gates are closed, the sluice can effectively block floods and tides, or raise the water level upstream to meet various needs such as irrigation, power generation, shipping, aquatic products, environmental protection, industrial and domestic water. When the gates are open, the sluice can quickly discharge floods, waterlogging, abandoned water or wastewater, and can also supply water to downstream rivers or channels. Therefore, in water conservancy projects, sluices, as an important water retaining, water discharging or water intake structure, are widely used and have diverse functions.

[0003] In the prior art, there is a hydraulic water retaining gate structure with a publication number of "CN209722895U", which includes a dam foundation, a first water trough recessed downwardly provided on the upper surface of the dam foundation, a gate, and a first hydraulic drive device and a second hydraulic drive device respectively arranged on the dam foundation; a second groove recessed downwardly provided at the bottom of the first water trough, a first plate provided at the bottom of the second groove; the first hydraulic drive device drives the gate and moves the gate up and down in a vertical direction, and the gate is located directly above the first plate; the second hydraulic drive device drives the first plate and moves the first plate up and down in a vertical direction. The utility model can simplify the gate installation structure and reduce the safety hazards when installing the gate.

[0004] However, the existing technology still has major deficiencies, such as:

[0005] In the actual operation of water conservancy projects, the opening and closing operations of the gates are not frequent. However, when using a screw-type gate hoist for these operations, the screw is easily oxidized and rusted by the transmission components because it is exposed to the outdoor environment for a long time. When the screw drives the gate to move up and down, these problems may lead to poor transmission effect and even jamming. In order to maintain the smooth operation of the screw-type gate hoist, the management and maintenance personnel of the water conservancy project need to regularly apply grease to the screw for maintenance. However, due to the long screw length and large height difference of the screw-type gate hoist, this maintenance work is somewhat dangerous. Therefore, we need a device that can automatically clean the screw when the screw-type gate hoist is working to ensure the efficient and safe operation of the equipment. Utility Model Content

[0032] In this embodiment, the design of the slideway 2 allows the gate 3 to slide freely therein to realize the opening and closing functions. A crossbeam 4 is fixed on the top of the slideway 2 to provide stable support for other key components. The base 1 and the slideway 2 are arranged between the gate piers. The gate piers are common knowledge in the field of water conservancy facilities and will not be described in detail here.

[0033] A rotating shaft 6 is rotatably arranged on the frame 5, and a worm 7 is fixed on the rotating shaft 6. At the same time, a worm wheel 8 perpendicular to the worm 7 is also installed on the frame 5 and is tightly meshed with the worm 7, ensuring efficient and stable power transmission. A screw 10 is movably arranged in a threaded hole 9 opened on the worm wheel 8, and one end of the screw 10 is fixedly connected to the gate 3. When the worm wheel 8 rotates under the drive of the worm 7, since the worm wheel 8 can only rotate on the bracket, the lifting and lowering movement of the gate 3 can be controlled through the interaction between the threaded hole 9 and the screw 10 to achieve the function of blocking and releasing water.

[0034] Embodiment 2:

[0035] On the basis of the first embodiment, in order to maintain the cleanliness of the screw 10 and extend its service life, a cleaning mechanism is also provided on the crossbeam 4;

[0036] The cleaning mechanism includes a rotating ring 12 rotatably arranged on the crossbar, a cleaning ring 13 is fixedly arranged on the rotating ring 12, and a cleaning brush 14 is arranged on the cleaning ring 13. The cleaning brush 14 can fit tightly against the screw 10 to effectively remove the debris and stains on the surface thereof, thereby ensuring the smooth operation of the screw 10;

[0037] A transmission shaft 15 is rotatably provided on the cross bar, a driven bevel gear 17 is fixedly provided at one end of the transmission shaft 15, a driving bevel gear 16 is rotatably provided on the rotating shaft 6, the driving bevel gear 16 is meshed with the driven bevel gear 17 for transmission, and this bevel gear transmission mode has the characteristics of compact structure and high transmission efficiency, ensuring the smooth transmission of power from the rotating shaft 6 to the transmission shaft 15, and the transmission shaft 15 then drives the rotating ring 12 to rotate through the first pulley set 18, thereby driving the cleaning brush 14 to clean the screw 10.

[0038] When the rotating shaft 6 rotates, the worm 7 drives the worm wheel 8 to rotate. When the worm wheel 8 rotates, the gate 3 is driven to achieve lifting movement through the interaction between the threaded hole 9 and the screw 10. At the same time, the rotating shaft 6 drives the transmission shaft 15 to rotate through the active bevel gear 16 and the driven bevel gear 17. The transmission shaft 15 drives the rotating ring 12 to rotate through the first pulley group 18. The cleaning brush 14 on the rotating ring 12 cleans the impurities on the screw 10. At the same time, the operator can also apply solid lubricating materials such as grease on the cleaning brush 14. When the screw 10 rises or falls, the lubricating material is evenly applied to the screw 10 to reduce the friction between the screw 10 and the threaded hole 9 and increase the service life of the components.

[0039] Embodiment three:

[0040] A driving motor 19 is also fixedly arranged on the crossbeam 4, and the driving motor 19 is connected to the rotating shaft 6 through the second pulley set 20. When the motor is started, it drives the rotating shaft 6 to rotate through the pulley set, thereby starting the working process of the entire water retaining structure of the gate 3. This driving mode has the advantages of rapid start-up and smooth operation, and provides reliable power guarantee for the efficient opening and closing of the gate 3;

[0041] In this embodiment, the drive motor 19 drives the rotating shaft 6 to rotate through the second pulley group 20, and the transmission is stable, the noise is low, and overload can be prevented to protect other parts from being damaged. The drive motor 19 is a device well known to technicians in the technical field and is a commonly used device in the field. It will not be described in detail here. The operator can select a suitable drive motor 19 according to the actual power or speed parameters required. The parameter model of the drive motor 19 is not limited here;

[0042] The rotating shaft 6 is rotatably arranged on the frame 5 through two bearings 21. The bearings 21 are arranged at both ends of the worm 7, which effectively reduces friction and wear and increases the service life of the rotating shaft 6. At the same time, this bearing 21 support structure also enhances the stability of the rotating shaft 6 and ensures its smooth rotation during operation.

[0043] A plurality of fixing frames 22 are fixedly arranged on the cross beam 4, such as Figure 5 As shown, the rotating ring 12 is provided with an annular groove 23 matching the fixing frame 22. This design enables the rotating ring 12 to realize stable rotation on the crossbeam 4 through the fixing frame 22. The fixing frame 22 is also fixedly provided with a plurality of connecting ears 24, which are fixedly provided on the crossbeam 4 by screws 25, further enhancing the connection stability between the rotating ring 12 and the crossbeam 4. At the same time, during maintenance, the operator can easily replace or maintain the rotating ring 12 by disassembling the fixing frame 22.

[0044] In order to protect the internal mechanical components from the external environment, a protective cover 26 is fixedly provided on the crossbeam 4.

The design of the protective cover 26 takes into account the protection requirements of the mechanical components and the overall aesthetics of the structure.

[0045] Working principle: During the use of the utility model, when the gate 3 needs to be opened and closed, the driving motor 19 is started, and the rotating shaft 6 is driven to rotate through the second pulley group 20. The worm 7 fixed on the rotating shaft 6 rotates accordingly, and meshes with the worm wheel 8 to achieve transmission. The rotation of the worm wheel 8 accurately controls the lifting and lowering movement of the gate 3 through the interaction between the threaded hole 9 and the screw 10. At the same time, the driven bevel gear 17 on the transmission shaft 15 meshes with the driving bevel gear 16 on the rotating shaft 6, and drives the rotating ring 12 to rotate through the first pulley group 18. The cleaning brush 14 on the rotating ring 12 is tightly attached to the surface of the screw 10, effectively removing the debris and stains thereon, and keeping the screw 10 clean and running smoothly.
