[0002] In my country, the development of water conservancy and hydropower projects is closely linked to ecological and environmental protection. Currently, when diverting water downstream, these projects must strictly adhere to water quality and temperature standards to maintain the stability of downstream ecosystems and meet diverse water demands. Large-scale water conservancy and hydropower projects are particularly prone to deep reservoirs, with the orifices of water intake structures often buried deep underwater to fully utilize the stored water. However, reservoir water temperature exhibits significant vertical stratification, with bottom water diverted from deep orifices exhibiting low temperatures and mineral parameters often exceeding standards.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0020] like Figure 1 and Figure 2 As shown, the stratified water intake device with a backup drive mechanism according to an embodiment of the present application includes: a door frame assembly 10, multiple drive mechanisms 30, and a clutch 40.

[0021] Specifically, the door frame assembly 10 is provided with a plurality of water intakes 11 arranged in sequence along the first direction, and a movable gate 20 is provided in each water intake 11. The door frame assembly 10 includes an installation cavity 12 arranged on both sides of the water intake 11; the driving mechanism 30 is arranged in the installation cavity 12, and every two driving mechanisms 30 correspond to a gate 20. The two driving mechanisms 30 corresponding to each gate 20 are respectively located on both sides of the gate 20. The driving mechanism 30 is transmission-connected to the gate 20 for driving the gate 20 to rotate to open or close the water intake 11. The driving mechanism 30 includes a first output shaft, and a first rotating shaft 23 is provided at both ends of the gate 20. The first output shaft, the clutch 40 and the first rotating shaft 23 are transmission-connected in sequence.

[0022] According to the stratified water intake device with a backup drive mechanism in the embodiment of the present application, the device has the ability to take water in stratified water. Water intakes 11 at different heights can correspond to water source layers with different water quality, water temperature or other characteristics. By opening water intakes 11 at different heights, water sources that meet the needs can be flexibly obtained. For example, in a reservoir, the surface water temperature is higher and the oxygen content is rich, while the bottom water temperature is lower and the water quality is relatively stable. The water intake layer can be selected as needed. The movable design of the gate 20 realizes the opening and closing control of the water intake 11. When water needs to be taken, the drive mechanism 30 drives the gate 20 to rotate and open the water intake 11; when water is not needed or the water intake layer needs to be switched, the corresponding water intake 11 is closed, thereby accurately controlling the on-off of the water flow and the water intake position. The installation cavity 12 on both sides of the water intake 11 provides a special installation space for the drive mechanism 30, isolates the drive mechanism 30 from the water flow, plays a role in protecting the drive mechanism 30, avoids the water flow from directly impacting and eroding the drive mechanism 30, reduces the occurrence of mechanical failures, and extends the service life of the drive mechanism 30. Every two drive mechanisms 30 correspond to one gate 20 and the two drive mechanisms 30 are respectively located on both sides of the gate 20. The drive mechanism 30 includes a first output shaft. The first output shaft serves as a power output component to transmit the power generated by the drive mechanism 30 to the clutch 40 and the first rotating shaft 23. The clutch 40 can control the first output shaft and the first rotating shaft 23. The transmission or disengagement of power between the two sides is realized. In this way, when the gate 20 needs to be driven, only the driving mechanism 30 on one side needs to maintain transmission with the gate 20, and the driving mechanism 30 on the other side is used as a backup. When the driving mechanism 30 on this side fails, it is disengaged from the driving mechanism 30 on this side, and the driving mechanism 30 on the other side is transmitted to the gate 20 through the clutch 40, thereby realizing the backup of the driving mechanism 30. Even if a certain driving mechanism 30 fails, the other backup driving mechanism 30 can also be quickly switched to work, thereby shortening the downtime of the stratified water intake device with a backup driving mechanism when a failure occurs, and ensuring the continuity of the water intake function.

[0023] like Figure 3 and Figure 4 As shown, according to the stratified water intake device with a backup driving mechanism according to an embodiment of the present application, the driving mechanism 30 includes an underwater stepping motor 32 , and the underwater stepping motor 32 includes a first output shaft, which is perpendicular to the first rotating shaft 23 .

[0024] In the above embodiment, the underwater stepper motor 32 is suitable for underwater environments and can provide stable power. The first output shaft is positioned perpendicular to the first rotating shaft 23, and the speed reduction assembly 31 changes the direction of power transmission, making the structure more compact. The speed reduction assembly 31 reduces speed and increases torque, ensuring that the gate 20 has sufficient torque to overcome resistance and rotate smoothly.

[0025] like Figure 3 and Figure 4As shown, in some embodiments, a bracket 13 is provided in the installation cavity 12, the first rotating shaft 23 is movably provided on the bracket 13, the door frame side column 14 and the connecting beam 15 jointly define the water intake 11, and the driving mechanism 30 also includes a reduction assembly 31, the reduction assembly 31 includes a first bevel gear 311 and a second bevel gear 312 that are meshed with each other, the second bevel gear 312 is sleeved on the first rotating shaft 23, and a clutch 40 is provided between the first bevel gear 311 and the first output shaft.

[0026] In some embodiments, guide vanes are provided at both the upstream and downstream ends of the door frame side column 14 along the water flow direction. The guide vanes have an arc-shaped surface and can guide the water flow through the outside of the installation cavity to reduce the impact load of the water flow.

[0027] In some embodiments, the door frame side column 14 may also be filled with a honeycomb aluminum alloy core material.

[0028] The gate 20 includes a first surface and a second surface that are arranged opposite to each other. When the gate 20 closes the water intake 11, the first surface is located below the second surface, and the first surface is in a convex arc shape relative to the second surface.

[0029] When the gate 20 is opened, the first surface is located below the second surface, and the arc surface guides the water flow downward to avoid the formation of backflow or vortex at the bottom, making the water flow transition more natural and smooth, which helps to maintain the uniformity of the water flow speed.

[0030] In some embodiments, the second surface and the first surface are symmetrically arranged along the central axis of the length direction of the gate 20 .

[0031] The gate 20 includes opposing first and second ends. When the gate 20 is closed, the first end is positioned above the second end, and the second end is positioned below the first end. The width of the first end is greater than that of the second end. The wider portion at the upper end increases the weight and cross-sectional area of ​​the first end of the gate 20, shifting the center of gravity downward and making the gate 20 more stable under the impact of water flow. The narrower second end reduces obstruction to water flow as it passes through the second end, allowing water to more smoothly exit the gate 20. This reduces friction and vortex formation between the water flow and the gate 20. According to the principles of fluid mechanics, this reduces flow resistance and reduces head loss as water flows through the gate 20. The distance between the first rotating shaft 23 and the first end is smaller than the distance between the first rotating shaft 23 and the second end. Under the action of a driving force, a smaller force can cause the first end to move first. At this point, the gate 20 rotates about the first rotating shaft 23. The opening of the first end acts like the short lever arm of a lever, easily breaking the static state of the water flow at the water intake 11. The narrower second end is then opened, reducing the initial water flow resistance, so that the water can flow into the water intake 11 more smoothly.

[0032] In the above embodiment, the bracket 13 provided in the mounting cavity 12 provides a stable and reliable support point for the first rotating shaft 23. The first rotating shaft 23 is movably provided on the bracket 13. This design ensures that the first rotating shaft 23 can flexibly rotate under the constraint of the bracket 13, reducing the shaking and offset during the rotation process, making the driving mechanism 30 more stable when transmitting power, thereby ensuring that the gate 20 connected thereto can be opened or closed smoothly, avoiding the gate 20 from being stuck or shaking abnormally due to the instability of the rotating shaft, and improving the accuracy and reliability of the opening and closing action of the water intake 11. The reduction assembly 31 in the driving mechanism 30 plays a vital role. The first bevel gear 311 and the second bevel gear 312 that are meshed with each other effectively achieve the effect of changing the direction of power transmission and reducing speed and increasing torque through the transmission between the gears.

[0033] Because the first output shaft is perpendicular to the first rotating shaft 23, the first bevel gear 311 is connected to the first output shaft, and the second bevel gear 312 is sleeved on the first rotating shaft 23. This structural design allows the high-speed, low-torque power output by the underwater stepping motor 32 to be converted into low-speed, high-torque power suitable for driving the gate 20 through the meshing of the bevel gears. This conversion process ensures that the gate 20 can obtain sufficient torque to overcome the resistance of the water flow and its own gravity during the opening and closing process, achieving smooth and powerful rotation, thereby ensuring that the water intake 11 can be smoothly opened and closed, meeting water intake requirements under different operating conditions. The clutch 40 is provided between the first bevel gear 311 and the first output shaft, providing a flexible control method for power transmission.

[0034] When the gate 20 needs to be driven, the clutch 40 closes, allowing the power of the first output shaft to be smoothly transmitted to the first bevel gear 311, thereby driving the second bevel gear 312 and the first rotating shaft 23 connected thereto to rotate, thereby opening or closing the gate 20. When the drive mechanism 30 needs to be inspected or maintained, or if a drive mechanism 30 is found to have a fault during operation, the power connection can be disconnected through the clutch 40. This operation not only ensures the safety of maintenance personnel, but also facilitates the removal, replacement, and repair of faulty components, reduces downtime caused by equipment failure, and improves the overall operating efficiency and maintainability of the stratified water extraction device with a backup drive mechanism. At the same time, the presence of the clutch 40 also provides a key control node for the backup function of the drive mechanism 30. When one side of the drive mechanism 30 is operating normally, the other side can serve as a backup. If a problem occurs on the working side, the clutch 40 can quickly switch to the backup drive mechanism 30, ensuring the continued stable operation of the device. like Figure 3 and Figure 4As shown, in some embodiments, the door frame assembly 10 includes two door frame side columns 14 arranged side by side and spaced apart, a plurality of connecting beams 15 are arranged between the two door frame side columns 14, the door frame side columns 14 define an installation cavity 12, and an inspection port is also provided on the door frame side column 14, the inspection port is connected to the installation cavity 12, and a removable baffle is provided in the inspection port.

[0035] In the above-described embodiment, the door frame side post 14 and the connecting beam 15 jointly define the water intake 11. This structural design not only determines the shape and position of the water intake 11 but also forms the basic framework of the entire door frame assembly 10. Furthermore, the installation cavity 12 cleverly utilizes the space within the door frame side post 14 to accommodate the drive mechanism 30. This not only ensures the compactness of the device structure but also achieves a reasonable functional division of each component. This results in a well-organized layout and a neat appearance for the entire tiered water intake device with a backup drive mechanism. It also possesses excellent structural strength, capable of withstanding the pressure of water flow and the forces acting on it by the external environment. The inspection port provided on the door frame side post 14, which communicates with the installation cavity 12 and is equipped with a removable baffle, greatly facilitates maintenance and repair of the device. When it is necessary to inspect, repair, or replace components of the drive mechanism 30 within the installation cavity 12, personnel can directly access the installation cavity 12 without extensive disassembly of the entire device. They simply open the removable baffle of the inspection port to begin work. This not only significantly shortens the time of equipment downtime for maintenance and reduces the impact of downtime on water extraction operations, but also reduces the difficulty and cost of maintenance work, improves the maintainability of the stratified water extraction device with a backup drive mechanism, ensures that the device can operate stably for a long time, and provides reliable guarantees for the rational allocation of water resources.

[0036] In some embodiments, an annular rubber sealing groove is provided on the inner wall of the installation cavity 12, and a silicone rubber sealing ring is embedded in the sealing groove. A conical drainage hole can also be provided at the bottom of the installation cavity 12, and a one-way valve is provided in the drainage hole to regularly drain condensed water or trace amounts of water that accidentally seeps in to prevent rust on components.

[0037] In some embodiments, the stratified water intake device with a backup drive mechanism also includes a gearbox 33, the reduction assembly 31 is arranged in the gearbox 33, and a first transparent cover 331 is provided at the end of the gearbox 33 close to the gate 20. The first transparent cover 331 is fixedly connected to the door frame side column 14. The first transparent cover 331 and the door frame side column 14 jointly define a first mounting hole, the first rotating shaft 23 is passed through the first mounting hole, and a first rolling bearing 338 is also clamped between the first mounting hole and the first rotating shaft 23.

[0038] In the above-described embodiment, the gearbox 33 houses the reduction assembly 31, providing it with a closed and stable working environment. In hydraulic environments, water flows are often mixed with silt, debris, and other debris. If the reduction assembly 31 is directly exposed, it is easily corroded and interfered with by these impurities, leading to problems such as increased gear wear, reduced transmission accuracy, and even jamming. The presence of the gearbox 33 effectively blocks external impurities, ensuring that the reduction assembly 31, including the first bevel gear 311 and the second bevel gear 312, can mesh and transmit in a clean and stable environment. This ensures the stability and reliability of power transmission, extends the service life of the reduction assembly 31, and reduces the risk of equipment downtime due to component failure.

[0039] The first transparent cover 331 of the gearbox 33, located near one end of the gate 20, is fixedly connected to the door frame side column 14 and together they define a first mounting hole. The first rotating shaft 23 is inserted into this hole, and a first rolling bearing 338 is interposed between the hole and the first rotating shaft 23. This structural design ensures precise positioning and reliable support for the first rotating shaft 23. The first rolling bearing 338 significantly reduces the friction during the rotation of the first rotating shaft 23, allowing the rotating shaft to rotate smoothly and ensuring the smooth opening and closing of the gate 20. At the same time, the close fit between the first transparent cover 331 and the door frame side column 14 ensures the dimensional accuracy and positional stability of the first mounting hole, preventing the first rotating shaft 23 from deflecting or shaking during rotation, thereby ensuring the accuracy of power transmission between the reduction gear assembly 31 and the gate 20, making the operation of the entire device more stable and efficient.

[0040] The fixed connection between the first transparent cover 331 and the door frame side column 14 not only functionally positions the first rotating shaft 23 and protects the reduction gear assembly 31, but also structurally enhances the integrity of the stratified water intake device with a backup drive mechanism. This connection tightly integrates the gearbox 33 and the door frame assembly 10 into a single unit, enabling the various components of the device to coordinate forces when subjected to water flow and other external forces, thereby improving the device's structural strength and impact resistance. This enhanced integrity helps ensure the device's long-term stable operation under complex hydraulic conditions, reduces failures caused by loose components or structural instability, and provides a solid structural guarantee for the device's reliable operation.

[0041] like Figure 3 and Figure 4 As shown, in some embodiments, a shaft sleeve 332 is further provided on the first rotating shaft 23, the shaft sleeve 332 is located in the gear box 33, the second bevel gear 312 is sleeved on the shaft sleeve 332 and connected to the shaft sleeve 332, a second transparent cover 333 is further provided between the second bevel gear 312 and the first transparent cover 331, the second transparent cover 333 is sleeved outside the shaft sleeve 332 and connected to the gear box 33, and a second rolling bearing 334 is further provided between the second transparent cover 333 and the shaft sleeve 332.

[0042] In the above-mentioned embodiment, the shaft sleeve 332 is mounted on the first rotating shaft 23, providing a stable mounting base for the second bevel gear 312. The shaft sleeve 332 is tightly fitted with the first rotating shaft 23, ensuring that the second bevel gear 312 can accurately follow the first rotating shaft 23 and rotate synchronously. This design effectively avoids the shaking or displacement that may occur during operation of the second bevel gear 312 due to being directly mounted on the first rotating shaft 23, and enhances the stability of the installation of the second bevel gear 312. The stable installation allows the second bevel gear 312 to always maintain a good meshing state when meshing with the first bevel gear 311 for transmission, reducing problems such as poor meshing and increased wear caused by unstable gear installation, thereby improving the reliability and efficiency of the transmission of the reduction assembly 31 and ensuring that the drive mechanism 30 can stably transmit power to the gate 20.

[0043] A second transparent cover 333 is positioned outside the shaft sleeve 332, and a second rolling bearing 334 is installed between the second transparent cover 333 and the shaft sleeve 332. This significantly reduces frictional resistance during the rotation of the shaft sleeve 332. When the first rotating shaft 23 drives the shaft sleeve 332 and the second bevel gear 312 mounted on the shaft sleeve 332 to rotate, the second rolling bearing 334 supports the rotation of the shaft sleeve 332 with minimal friction, making the rotation process smoother. Compared to a design without the second rolling bearing 334, this design significantly reduces energy loss and improves the efficiency of power transmission. Furthermore, the reduced frictional resistance helps reduce wear on components such as the shaft sleeve 332, the second transparent cover 333, and the second bevel gear 312, extending their service life and further enhancing the operational stability and reliability of the entire device.

[0044] like Figure 3 and Figure 4 As shown, in some embodiments, the first rotating shaft 23 extends along the second direction, a second rotating shaft 313 is fixed on the first bevel gear 311, the second rotating shaft 313 extends along the first direction, and the second rotating shaft 313 is connected to the first output shaft through a clutch 40, wherein the second direction is perpendicular to the first direction.

[0045] In the above embodiment, the second rotating shaft 313 is arranged perpendicular to the first rotating shaft 23, receiving power from the first output shaft. Through its tight connection with the first bevel gear 311, it precisely converts the power vertically and transmits it to the second bevel gear 312 connected to the first rotating shaft 23. This bridges the power transmission gap between the reduction assembly 31 and the gate 20, ensuring accurate power transmission and enabling stable and efficient operation of the entire device.

[0046] like Figure 3 and Figure 4As shown, in some embodiments, a second mounting hole is further provided on the gear box 33, the second rotating shaft 313 is passed through the second mounting hole, a third transparent cover 335 is further provided in the second mounting hole, the third transparent cover 335 is sleeved outside the second rotating shaft 313, the third transparent cover 335 is fixedly connected to the gear box 33, and a plurality of third rolling bearings 336 are further provided between the third transparent cover 335 and the second rotating shaft 313.

[0047] In the above-mentioned embodiment, the provision of multiple third rolling bearings 336 greatly reduces the friction force during the rotation of the second rotating shaft 313, allowing the second rotating shaft 313 to rotate smoothly and stably in the second mounting hole. This structural design ensures the stability and accuracy of the second rotating shaft 313 during power transmission, and avoids power transmission deviation caused by shaking or offset of the second rotating shaft 313. Since one end of the second rotating shaft 313 is connected to the first bevel gear 311 and the other end is associated with the first output shaft, its stable operation is crucial to the power transmission of the entire drive system. It ensures that the power from the first output shaft to the first bevel gear 311 can be transmitted stably and efficiently, thereby driving the second bevel gear 312 and the first rotating shaft 23 to rotate, and ultimately achieving stable driving of the gate 20, further improving the reliability and stability of the stratified water intake device with a backup drive mechanism.

[0048] like Figure 3 and Figure 4 As shown, in some embodiments, a fourth transparent cover 337 is further provided on the side of the third transparent cover 335 close to the clutch 40 , the fourth transparent cover 337 is connected to the gearbox 33 , and the side of the fourth transparent cover 337 close to the third transparent cover 335 abuts against the adjacent third rolling bearing 336 .

[0049] In the above-described embodiment, during operation of the stratified water intake device with a backup drive mechanism, the second rotating shaft 313 continuously rotates, subjecting the third rolling bearing 336 to certain axial and radial forces. The fourth transparent cover 337, by abutting against the third rolling bearing 336, effectively prevents axial displacement of the third rolling bearing 336 during operation, ensuring it remains in the correct position and stably supports the second rotating shaft 313. Because the second rotating shaft 313 plays a critical role in power conversion and transmission in the entire power transmission chain, its stable operation is directly related to the accurate and efficient transmission of power from the first output shaft to the first bevel gear 311, thereby driving the second bevel gear 312 and the first rotating shaft 23, thereby achieving stable control of the gate 20. Therefore, the fourth transparent cover 337 optimizes the stability of the entire power transmission process by stabilizing the third rolling bearing 336, further improves the reliability of the operation of the stratified water intake device with a backup drive mechanism, reduces the power transmission deviation and equipment failure risks caused by component displacement, and ensures that the stratified water intake device with a backup drive mechanism can operate stably for a long time in a complex water environment and continuously and efficiently complete the stratified water intake task.

[0050] like Figure 1 and Figure 2 As shown, according to the stratified water intake device with a backup drive mechanism of an embodiment of the present application, the gate 20 includes a first surface 21 and a second surface 22 arranged opposite to each other. When the gate 20 closes the water intake 11, the first surface 21 is on the outside. When the gate 20 opens the water intake 11, the first surface 21 is located below the second surface 22. The first surface 21 is in a protruding arc shape relative to the second surface 22. The second surface 22 and the first surface 21 are symmetrically arranged along the central axis of the length direction of the gate 20.

[0051] According to the stratified water intake device with a backup drive mechanism in an embodiment of the present application, the gate 20 includes a first surface 21 and a second surface 22 arranged opposite to each other. When the gate 20 closes the water intake 11, the first surface 21 is on the outside. When the gate 20 opens the water intake 11, the first surface 21 is located below the second surface 22. The first surface 21 is in the shape of a protruding arc relative to the second surface 22.

[0052] Specifically, when gate 20 is open, first surface 21 is located below second surface 22. The curved surface guides the water downward, preventing backflow or vortexes at the bottom. This creates a more natural and smooth transition, helping to maintain uniform water flow. The symmetry of first surface 21 and second surface 22 along the central axis ensures that gate 20 is evenly stressed from top to bottom under the impact of the water flow. Even in situations where the water flow is variable and directionally complex, the symmetrical structure prevents gate 20 from twisting or shifting due to uneven force, maintaining its stable opening and ensuring the continuity and safety of the water intake process. Even during floods, when the impact of the water flow increases significantly, the symmetrical gate 20 maintains stable operation, ensuring that water intake is not affected.
