Description

A layered water intake inlet grid structure Technical Field

[0001] This application relates to the field of water intake engineering technology, specifically to a layered water intake inlet grid structure. Background Technology

[0002] Reservoir intakes (such as those for hydropower stations or for water supply and irrigation) are mostly built below the reservoir's dead water level, ensuring a relatively stable water temperature at the intake. However, this also leads to significant changes in downstream river temperatures compared to before the reservoir's construction—lower temperatures in summer and higher temperatures in winter—which negatively impacts native organisms in the downstream river. Therefore, for rivers with ecological protection requirements, it is necessary to maintain the downstream water temperature as closely as possible to its natural state, preserving its inherent seasonal variations. Summary of the Invention

[0003] This application provides a layered water intake inlet grid structure, which can reduce the adverse effects caused by the large changes in downstream river water temperature due to upstream water storage.

[0033] As shown in Figures 1-9, this application embodiment provides a layered water intake inlet grille structure, which mainly includes a concrete frame structure 1 and an opening and closing gate. The concrete frame structure 1 is arranged enclosing the upstream side of the water intake 2, and both sides of the concrete frame structure 1 are connected to the mountainside on one side of the water intake 2. The concrete frame structure 1 is provided with multiple sets of water inlets, each set including at least one water inlet, and the multiple sets of water inlets are spaced apart along the height direction of the concrete frame structure 1. The opening and closing gate includes a drive component and a gate 3. The gate 3 is movably disposed at the position of the water inlet, and the drive component is connected to the gate 3 and can drive the gate 3 to open and close the corresponding water inlet.

[0034] In this embodiment, the layered water intake bar structure uses multiple sets of inlets and gates 3 spaced apart along the height of the concrete frame structure 1 to draw water in layers. This allows water at different depths to reach the intake 2 and be discharged downstream, thereby reducing the adverse effects of significant temperature changes in the downstream river channel caused by upstream water storage and contributing to the protection of the downstream river's ecological environment. Furthermore, the layered water intake bar gates 3 have low seepage requirements, low head effect during closure, are lightweight, and can be opened and closed in situ, resulting in lower power consumption.

[0035] As shown in Figures 1-5, in one specific embodiment, the concrete frame structure 1 adopts a concrete beam-column structure. The concrete frame structure 1 includes a first wall portion 11 and two second wall portions 12. The first wall portion 11 faces the water intake 2, and the two second wall portions 12 are located on both sides of the first wall portion 11. Both the first wall portion 11 and the second wall portion 12 are provided with multiple sets of water inlets and gate valves. Generally, the number of water inlets and gate valves provided at the first wall portion 11 is greater than the number of water inlets and gate valves provided at the second wall portions 12. The specific number can be preset according to the contact area between the two and the water body, etc., which is not specifically limited in this article. In addition, the number of water inlets provided on the side closer to the top in the direction from the bottom to the top of the concrete frame structure 1 can be the largest.

[0036] In this embodiment, the concrete frame structure 1 is arranged in a U-shape upstream and on both sides of the water intake 2, and connects to the mountain on one side of the water intake 2, forming an enclosure around the water intake 2, so that the water entering the water intake 2 passes through the water intake grille. Multiple water inlets are arranged in the concrete frame structure 1 between the normal water level and the bottom elevation of the water intake 2. Each water inlet is equipped with a horizontally rotating gate 3. By opening the gates 3 at different elevations, the water temperature of the discharged water can be controlled.

[0037] As shown in Figures 3-5, in one specific embodiment, the gate 3 includes a gate shaft 31 and a gate leaf 32. The gate shaft 31 is vertically arranged in the middle of the inlet. The concrete frame structure 1 has a gate shaft groove 13 pre-set at the position corresponding to the gate shaft 31. The upper and lower ends of the gate shaft 31 are movably set in the corresponding gate shaft groove 13. The gate leaf 32 is fixedly connected to the gate shaft 31. The driving component is connected to the gate shaft 31 and can drive the gate shaft 31 to rotate. When the driving component drives the gate shaft 31 to rotate, the gate shaft 31 can synchronously drive the gate leaf 32 to rotate, thereby opening or closing the inlet at the corresponding position.

[0038] As shown in Figures 3-7, in one specific embodiment, each set of water inlets is respectively provided with a set of driving components. The driving components include an opening and closing shaft 4 and a transmission component 5. The transmission component 5 includes a first force transmission rod 51, a linkage rod 52 and a second force transmission rod 53. The opening and closing shaft 4 is fixedly connected to one end of the first force transmission rod 51, the other end of the first force transmission rod 51 is slidably hinged to the linkage rod 52, the linkage rod 52 is hinged to one end of the second force transmission rod 53, and the other end of the second force transmission rod 53 is fixedly connected to the corresponding door hinge 31.

[0039] In this embodiment, rotating the opening and closing shaft 4 causes the transmission component 5 to drive the gate 3 to rotate. The opening and closing shaft 4 is fixedly connected to the first force transmission rod 51, and the gate shaft 31 is fixedly connected to the second force transmission rod 53. The linkage rod 52 is hinged to the second force transmission rod 53, and the first force transmission rod 51 is slidably hinged to the linkage rod 52. Of course, in some other embodiments, the opening and closing shaft 4 can drive the gate 3 to rotate through the transmission component 5 with other structures. Such a transmission component 5 should also fall within the protection scope of this application. Other equivalent embodiments of the transmission component 5 will not be elaborated upon here.

[0040] As shown in Figures 1-2, in one specific embodiment, the concrete frame structure 1 has a sleeve 14 pre-installed at at least part of the water inlet side position. The sleeve 14 is formed by drilling and embedding a steel pipe, and a steel plate 6 of a preset thickness is provided at the bottom of the drill hole. The opening and closing shaft 4 is movably installed in the sleeve 14. The drill hole has a notch reserved at the position corresponding to the first force transmission rod 51 and forms a rotating cavity 15.

[0041] In one specific embodiment, the two ends of the opening / closing shaft 4 and / or the gate shaft 31 are arc-shaped or conical, thereby reducing the contact surface of the rotating parts. Alternatively, the opening / closing shaft 4 and / or the gate shaft 31 are movably connected to the concrete frame structure 1 through rolling bearings. Additionally, this layered water intake inlet bar structure also includes a power unit 9 and a water level monitoring device (not shown in the figure). The power unit 9 is drively connected to the opening / closing shaft 4 and can drive the opening / closing shaft 4 to rotate. The power unit 9 includes a turntable or motor installed at the top of the opening / closing shaft 4. The water level monitoring device is electrically connected to the power unit 9 and is used to control the working state of the power unit 9 according to the water level. By monitoring conditions such as water level depth and temperature, the power unit 9 can be adjusted, ultimately allowing the gates 3 at different depths to open and close, thereby better controlling the temperature of the discharged water. Simultaneously, it can achieve opening and closing at specific water levels, realizing automated operation.

[0042] As shown in Figures 8-9, in one specific embodiment, a steel plate 6 is provided at the bottom of the gate shaft groove 13, and a semi-circular steel pipe 7 is pre-embedded on the downstream side of the gate shaft groove 13, and an installation notch is pre-set on the upstream side; after the gate 3 is installed, a limiting anchor plate 8 is provided on one side of the installation notch of the gate shaft groove 13, and the limiting anchor plate 8 is anchored to the concrete frame structure 1 by bolts.

[0043] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
