Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering equipment technology, and more specifically, to an automatic lifting and lowering type of drift barrier at the inlet of a hydropower station generator set. Background Technology

[0002] Flood barriers are facilities installed at the water intake of hydropower station generator units and other water bodies to intercept floating debris on the water surface. During the operation of a hydropower station, if floating debris such as tree branches and plastic waste enters the generator unit, it can cause wear, blockage, or even damage to components such as turbine blades and water guide mechanisms, seriously affecting power generation efficiency and equipment lifespan, and may also cause safety accidents. Therefore, flood barriers are crucial to ensuring the stable and safe operation of hydropower stations.

[0003] However, existing drift barriers have many shortcomings: 1. Their length is difficult to adapt flexibly to different water depths and widths, and they need to be frequently adjusted manually when the water level changes; 2. The inconvenience of installation and disassembly and the difficulty of maintenance greatly limit the effectiveness and efficiency of drift barriers.

[0004] Therefore, there is an urgent need for an automatic lifting and lowering type of drift barrier at the water inlet of a hydropower station generator set to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an automatic lifting and lowering drift barrier at the water inlet of a hydropower station generator set to solve the problems mentioned in the background art.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0007] An automatic lifting drift barrier at the intake of a hydropower station generator unit includes a fixed frame, wherein multiple sets of fixed frames are provided, and further includes:

[0008] An extension assembly includes symmetrically formed grooves on the outer wall of a fixed frame, a slider slidably connected to the inner wall of the groove, a lifting frame fixedly connected to the outer wall of the slider, and symmetrically distributed locking blocks fixedly connected to the outer wall of the fixed frame. Adjacent locking blocks are connected by a quick-connect assembly.

[0009] A floating component is disposed on the outer wall of the lifting frame, and the floating component cooperates with the extension component.

[0011] As a preferred technical solution of this application, the floating component includes a storage rack fixedly connected to the outer wall of the lifting frame, the inner wall of the storage rack is provided with multiple sets of floating balls, the outer wall of the storage rack is rotatably connected with a cover plate, and the outer wall of the cover plate is provided with symmetrically distributed positioning grooves.

[0012] As a preferred technical solution of this application, the top wall of the sliding frame is fixedly connected with symmetrically distributed strong springs, and the end of the strong springs away from the sliding frame is fixedly connected to the connecting block.

[0013] As a preferred technical solution of this application, the inner wall of the sliding frame is provided with a guide groove, and a guide block is slidably connected to the inner wall of the guide groove, and the guide block is fixedly connected to the moving block.

[0014] As a preferred technical solution of this application, both the fixed frame and the outer wall of the lifting frame are fixedly connected with side sealing plates, and the outer walls of adjacent side sealing plates abut against each other.

[0015] As a preferred technical solution of this application, the outer wall of the fixing frame is fixedly connected with symmetrically distributed end sealing plates, and the outer wall of the end sealing plates abuts against the outer wall of the connecting block.

[0016] As a preferred technical solution of this application, the outer wall of the card block is provided with uniformly distributed grooves, and the grooves are slidably connected to the protrusions.

[0018] As a preferred technical solution of this application, both the lifting frame and the inner wall of the fixed frame are fixedly connected with evenly distributed drift-blocking plates.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] In the scheme of this application:

[0021] 1. The length of the drift barrier can be flexibly adjusted according to actual needs through the set quick connection components, which is suitable for the water inlet of hydropower station generator sets of different widths, improving the versatility and applicability of the equipment. At the same time, the extension components can automatically rise and fall with the water level. No matter whether the water level rises or falls, the drift barrier can maintain a suitable height to intercept floating objects without the need for frequent manual adjustments, saving manpower and time costs, improving drift interception efficiency, and solving the problem that the length is difficult to flexibly adapt to different water depths and widths in the existing technology, and that frequent manual adjustments are required when the water level changes.

Simultaneously, the cover plate design of the floating components facilitates the maintenance and replacement of the floating balls, ensuring the drift barrier always maintains excellent buoyancy. This solves the problems of inconvenient installation and disassembly, and difficult maintenance in existing technologies, which greatly limit the effectiveness and efficiency of the drift barrier.

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0034] like Figure 1-8 As shown, the automatic lifting type float barrier at the intake of a hydropower station generator unit proposed in this embodiment includes a fixed frame 1, which is provided with multiple sets, and also includes:

[0035] The extension component includes symmetrically opened grooves 2 on the outer wall of the fixed frame 1. A slider 3 is slidably connected to the inner wall of the groove 2. A lifting frame 4 is fixedly connected to the outer wall of the slider 3. A symmetrically distributed locking block 8 is fixedly connected to the outer wall of the fixed frame 1. Adjacent locking blocks 8 are connected by a quick-connect component. With the cooperation of the slider 3 and the groove 2, the lifting frame 4 can slide up and down along the fixed frame 1, driving the floating component and the float plate 7 to rise and fall, which is suitable for water levels of different heights.

[0036] A floating component is installed on the outer wall of the lifting frame 4, and the floating component cooperates with the extension component.

[0037] like Figure 4-6 As shown, in a preferred embodiment, based on the above method, the quick-connect assembly further includes a connecting block 9 slidably connected to the outer wall of the locking block 8, a sliding frame 12 slidably connected to the inner wall of the connecting block 9, a bidirectional screw 13 rotatably connected to the outer wall of the sliding frame 12, a knob 14 fixedly connected to the outer wall of the bidirectional screw 13, and symmetrically distributed moving blocks 17 threadedly connected to the outer wall of the bidirectional screw 13. A protrusion 11 is fixedly connected to the outer wall of the moving blocks 17. When it is necessary to adjust the length of the drift barrier, the locking blocks 8 of adjacent fixing frames 1 are connected through the quick-connect assembly. In specific operation, rotating the knob 14 drives the bidirectional screw 13 to rotate. The symmetrically distributed moving blocks 17 on the bidirectional screw 13 move along the bidirectional screw 13 under the guidance of the guide groove 15 and the guide block 16. The moving blocks 17 drive the protrusion 11 to move, which in turn drives the groove 10 and the locking block 8 to move, thereby causing the side sealing plates 5 to press against each other, improving the sealing performance while strengthening the connection between the locking blocks 8. A sufficient number of fixing frames 1 can be installed as needed, and a corresponding number of lifting frames 4 can be installed similarly.

[0038] like Figure 7As shown, in a preferred embodiment, based on the above method, the floating component further includes a storage rack 19 fixedly connected to the outer wall of the lifting frame 4. The inner wall of the storage rack 19 is provided with multiple sets of floating balls 20. The outer wall of the storage rack 19 is rotatably connected to a cover plate 21. The outer wall of the cover plate 21 has symmetrically distributed positioning grooves 23. When the water level changes, the multiple sets of floating balls 20 on the inner wall of the storage rack 19 provide buoyancy, so that the float barrier floats on the water surface, making it convenient to maintain or replace the floating balls 20. With the cooperation of the slider 3 and the slide groove 2, the lifting frame 4 can slide up and down along the fixed frame 1, driving the floating component and the float barrier 7 to rise and fall, always maintaining a suitable position to intercept floating objects. The side sealing plate 5 of the fixed frame 1 and the outer wall of the lifting frame 4, and the end sealing plate 6 of the outer wall of the fixed frame 1 can reduce the situation where floating objects bypass the float barrier from the side or end.

[0039] like Figure 5 As shown, in a preferred embodiment, based on the above method, the top wall of the sliding frame 12 is further provided with symmetrically distributed strong springs 18, and the end of the strong spring 18 away from the sliding frame 12 is fixedly connected to the connecting block 9. The strong spring 18 on the top wall of the sliding frame 12 can provide a certain preload force to the protrusion 11 when the quick connection assembly is connected, thereby enhancing the stability of the connection.

[0040] like Figure 6 As shown, in a preferred embodiment, based on the above method, a guide groove 15 is further provided on the inner wall of the sliding frame 12, and a guide block 16 is slidably connected to the inner wall of the guide groove 15. The guide block 16 is fixedly connected to the moving block 17, and the guide groove 15 provides a limiting force for the sliding of the guide block 16, that is, it limits the direction of the moving block 17.

[0041] like Figure 1 As shown, in a preferred embodiment, based on the above method, both the outer walls of the fixed frame 1 and the lifting frame 4 are fixedly connected with side sealing plates 5, and the outer walls of adjacent side sealing plates 5 abut against each other. The side sealing plates 5 on the outer walls of the fixed frame 1 and the lifting frame 4 can reduce the situation where floating objects bypass the drift barrier from the side.

[0042] like Figure 1 As shown, in a preferred embodiment, based on the above method, the outer wall of the fixing frame 1 is further provided with symmetrically distributed end sealing plates 6, and the outer wall of the end sealing plates 6 abuts against the outer wall of the connecting block 9. The end sealing plates 6 on the outer wall of the fixing frame 1 can reduce the situation where the end of the floating object bypasses the drift barrier.

[0043] like Figure 4-5As shown, in a preferred embodiment, based on the above method, the outer wall of the card block 8 is further provided with uniformly distributed grooves 10, and the grooves 10 are slidably connected with the protrusions 11. The moving block 17 drives the protrusions 11 to move, which in turn drives the grooves 10 and the card block 8 to move, thereby driving the side sealing plates 5 to press against each other, improving the sealing performance while strengthening the connection between the card blocks 8.

[0044] like Figure 7-8 As shown, in a preferred embodiment, based on the above method, the outer wall of the storage rack 19 is further fixedly connected with symmetrically distributed arc-shaped buckles 22, and the outer wall of the arc-shaped buckles 22 abuts against the inner wall of the positioning groove 23. The cover plate 21 can rotate around the storage rack 19, and the arc-shaped buckles 22 cooperate with the positioning groove 23 to realize the opening and closing and fixing of the cover plate 21.

[0045] like Figure 1-2 As shown, in a preferred embodiment, based on the above method, both the lifting frame 4 and the inner wall of the fixed frame 1 are fixedly connected with evenly distributed drift-blocking plates 7, which are used to intercept drifting objects.

[0046] Specifically, when using the automatic lifting drift barrier at the intake of the generator unit of this hydropower station: when it is necessary to adjust the length of the drift barrier, connect the locking blocks 8 of adjacent fixed frames 1 through the quick-connect assembly. In specific operation, turn the knob 14 to drive the bidirectional screw 13 to rotate. The moving blocks 17 symmetrically distributed on the bidirectional screw 13 move along the bidirectional screw 13 under the guidance of the guide groove 15 and the guide block 16. The moving blocks 17 drive the protrusion 11 to move, which in turn drives the groove 10 and the locking block 8 to move, thereby driving the side sealing plates 5 to squeeze against each other, improving the sealing performance and strengthening the connection between the locking blocks 8. Install a sufficient number of fixed frames 1 as needed, and similarly install a corresponding number of lifting frames 4; when the water level changes, the storage rack 19... Multiple sets of floating balls 20 on the inner wall provide buoyancy, allowing the float barrier to float on the water surface. The cover plate 21 can rotate around the storage frame 19. The arc-shaped buckle 22 cooperates with the positioning groove 23 to realize the opening and closing and fixing of the cover plate 21, which facilitates the maintenance or replacement of the floating balls 20. The lifting frame 4 can slide up and down along the fixed frame 1 with the cooperation of the slider 3 and the sliding groove 2, driving the floating components and the float barrier 7 to rise and fall, always maintaining a suitable position to intercept floating objects. The side sealing plate 5 on the outer wall of the fixed frame 1 and the lifting frame 4, and the end sealing plate 6 on the outer wall of the fixed frame 1 can reduce the situation where floating objects bypass the float barrier from the side or end. The strong spring 18 on the top wall of the sliding frame 12 can provide a certain pre-tightening force to the protrusion 11 when the quick connection components are connected, enhancing the stability of the connection.

Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above.
