Description

Technical Field

[0001] This utility model belongs to the field of water conservancy engineering technology, specifically a sedimentation basin for mountain irrigation areas. Background Technology

[0002] Due to the long canal routes, diverse structures, and complex hydrological and geological conditions along mountain irrigation areas, the natural deposition of silt in the canals and their structures can affect their normal operation. The siltation at aqueduct transition sections, in particular, requires close attention, as it directly impacts the safety of the aqueduct and the irrigation and drainage functions of the irrigation district. Furthermore, dredging aqueducts is more labor-intensive and time-consuming than other canal sections. Therefore, various types of sedimentation basins are frequently installed in water conservancy projects. These sedimentation basins can be broadly categorized into two types: those installed within the canal section and those installed outside the canal section. Regardless of the type, sedimentation basins... There are problems such as high cost and complicated operation. Taking the sedimentation basin set up in the canal section as an example, during normal sedimentation, it is necessary to open the upstream and downstream gates of the sedimentation basin and close the upstream and downstream gates of the temporary water flow channel outside the sedimentation basin. When it is necessary to remove sediment from the sedimentation basin, it is necessary to open the upstream and downstream gates of the temporary water flow channel outside the sedimentation basin and close the upstream and downstream gates of the sedimentation basin. The design and operation principle of sedimentation basins set up outside the canal section are the same, that is, the sedimentation basin system must be equipped with four sluice gates, which is costly and complicated to operate. In view of the above situation, it is very necessary to design a sedimentation basin that is inexpensive and easy to operate. Summary of the Invention

[0003] To address the aforementioned problems in the existing technology, this utility model provides a sedimentation basin for irrigation areas in mountainous regions.

[0004] The aforementioned sedimentation basin in a mountain irrigation area comprises a right wing wall, a left wing wall, a right side bottom plate, a perimeter wall, a bottom plate, a working platform support wall, a rotating gate, a guide wall, a rotating gate central shaft, a working platform, waterproof tape A, waterproof tape B, a groove in the right wing wall, a rotating wheel, waterproof tape C, waterproof tape D, a transition inclined plate, a sand discharge pipe, and a sand discharge pipe valve. Its distinguishing feature is that the right wing wall, left wing wall, right side bottom plate, perimeter wall, bottom plate, working platform support wall, guide wall, and transition inclined plate are integrally cast in concrete and fixedly installed together; the working platform is placed on... The right wing wall of the sedimentation tank and the supporting wall of the working platform are located on the upper part of the sedimentation tank. The central axis of the rotating gate is fixedly installed with the rotating gate, and the rotating wheel is fixedly installed with the central axis of the rotating gate. The sand discharge pipe is fixedly installed on the wall of the sedimentation tank, and the sand discharge pipe valve is fixedly installed on the sand discharge pipe. The rotating gate of the sedimentation tank in a mountain irrigation area is fixedly installed with angle steel to form a keel frame in the middle, and stainless steel plate is fixedly installed on the outer perimeter of the frame. The working platform is made of reinforced concrete. The bottom plate of the right side of the sedimentation tank and the working platform have corresponding circular holes that are hinged to the central axis of the rotating gate. The rotating gate is hinged to the working platform and the bottom plate of the right side of the sedimentation tank. The right wing wall of the sedimentation tank has a groove on the inner side.

[0005] Furthermore, in a sedimentation tank in a mountainous irrigation area, waterproof tape A is fixedly installed on the groove of the right wing wall of the sedimentation tank, waterproof tape B is fixedly installed on the outer side of the upstream end of the rotating gate, waterproof tape C is fixedly installed on the inner side of the downstream end of the rotating gate, and waterproof tape D is fixedly installed on the bottom of the inner side of the rotating gate.

[0006] This utility model provides a sedimentation basin for mountain irrigation areas, which has the following advantages: water flows into the main body of the sedimentation basin and moves in a circular motion, resulting in a large cross-sectional area, low flow velocity, long flow path, and good sedimentation effect; the near-circular sedimentation basin wall reduces material usage and cost compared to a rectangular sedimentation basin with two side walls, under the same flow path and flow area; although this sedimentation basin is set up within a canal section, it solves the problem of four sluice gates in traditional sedimentation basins with a single gate, greatly reducing project costs, and is simple and convenient to operate.

Detailed Implementation

[0008] The present invention will be further described below with reference to the accompanying drawings.

[0009] As shown in the figure, a sedimentation basin in a mountain irrigation area consists of a right wing wall 1, a left wing wall 2, a right side bottom plate 3, a perimeter wall 4, a bottom plate 5, a working platform support wall 6, a rotating gate 7, a guide wall 8, a rotating gate central shaft 9, a working platform 10, waterproof tape A11, waterproof tape B12, a groove 13 in the right wing wall 13, a rotating wheel 14, waterproof tape C15, waterproof tape D16, a transition inclined plate 17, a sand discharge pipe 18, and a sand discharge pipe valve 19. The right wing wall 1 and the left wing wall of the sedimentation basin... 2. The right side bottom plate of the sedimentation tank 3, the sedimentation tank enclosure wall 4, the sedimentation tank bottom plate 5, the working platform support wall 6, the guide wall 8, and the transition inclined plate 17 are all integrally cast with concrete and fixed together; the working platform 10 is placed on the right wing wall 1 and the working platform support wall 6 of the sedimentation tank to facilitate the operation of the rotating gate by the staff; the central axis 9 of the rotating gate is fixedly set with the rotating gate 7, and the rotating wheel 14 is fixedly set with the central axis 9 of the rotating gate; the sand discharge pipe 18 is fixedly set on the sedimentation tank enclosure wall 4, and the sand discharge pipe valve 19 is fixedly set on the sand discharge pipe 18.

[0010] The rotating gate 7 is fixed in the middle with angle steel to form a keel frame, and stainless steel plates are fixed on the outside of the frame, making it lightweight and easy to open and close. The working platform 10 is made of reinforced concrete. The right bottom plate 3 of the sedimentation tank and the working platform 10 have corresponding round holes that are hinged to the central axis 9 of the rotating gate. The rotating gate 7 is hinged to the working platform 10 and the right bottom plate 3 of the sedimentation tank. That is, the central axis 9 of the rotating gate is embedded in the corresponding round holes of the right bottom plate 3 of the sedimentation tank and the working platform 10. The right wing wall 1 of the sedimentation tank has a right wing wall groove 13 on the inner side, which makes the rotating gate more stable when the sedimentation tank is working.

[0011] The waterproof tape A11 is fixedly installed on the groove 13 of the right wing wall of the sedimentation tank, the waterproof tape B12 is fixedly installed on the outer side of the upstream end of the rotating gate 7, the waterproof tape C15 is fixedly installed on the inner side of the downstream end of the rotating gate 7, and the waterproof tape D16 is fixedly installed on the bottom of the inner side of the rotating gate 7. These waterproof tapes are used to ensure that the sedimentation tank can work normally.

[0012] Figure 11 The sedimentation basin system currently installed within the canal section consists of sedimentation basin 30, upstream sluice gate 31 of sedimentation basin, downstream sluice gate 32 of sedimentation basin, temporary water flow channel 33 outside sedimentation basin, upstream sluice gate 34 of temporary water flow channel outside sedimentation basin, downstream sluice gate 35 of temporary water flow channel outside sedimentation basin, and the existing canal; the arrows in the attached diagram all indicate the direction of water flow.

[0013] A method for using a sedimentation tank in a mountain irrigation area is as follows: During normal operation, on the working platform, the rotating wheel is manually or mechanically driven to the upstream end of the rotating gate, entering the groove on the right wing wall of the sedimentation tank. The inlet and outlet of the sedimentation tank are fully opened, allowing water to flow into the main body of the sedimentation tank. The main body of the sedimentation tank is nearly circular. Under the action of the guide plate, the water flows in a circular motion within the main body of the sedimentation tank. Figure 1 As shown, the cross-sectional area of ​​the water flow suddenly increases, the flow velocity decreases sharply, and the sediment carried by the water sinks to the bottom of the pool. The clear water flows around once and then flows back to the channel through the main outlet of the sedimentation tank. When it is necessary to clean the sediment, on the working platform, the rotary wheel can be manually or mechanically driven to turn the gate to simultaneously close the inlet and outlet of the main body of the sedimentation tank. The water flows normally through the channel between the right and left wing walls of the sedimentation tank. If the sedimentation tank is located in front of the aqueduct transition section, and the terrain allows, the sediment in the sedimentation tank can be discharged into the corresponding river channel by opening the discharge pipe valve. If the terrain prevents automatic discharge, the sedimentation tank does not need to be equipped with a discharge pipe, and the sediment can be removed by conventional methods.
