Description

Technical Field

[0001] This application relates to a bottom-flow sluice gate. Background Technology

[0002] When a river is blocked, organic matter easily accumulates at the bottom, leading to eutrophication. Currently, dredging is commonly used to mitigate this, but this method is costly and inconvenient. To address these issues, some systems employ bottom flow mechanisms. However, existing structures typically use gate systems, which are susceptible to siltation, resulting in incomplete sealing. Therefore, it is necessary to modify the gate structure's operation to accommodate siltation at the riverbed. Utility Model Content

[0003] To address the aforementioned problems, this application proposes a bottom-flow sluice gate, comprising a bottom baffle at the bottom, several bottom channels on the bottom baffle, and a transverse dam body on the bottom baffle; an outer blocking part is provided on the outside of the bottom channels, the outer blocking part being movably sealed onto the bottom channels, and a power unit for driving the outer blocking part is provided on one side of the outer blocking part. This application employs the coordinated arrangement of the outer blocking part and the power unit, which can effectively control the opening and closing of the bottom channels, avoiding blockages, and demonstrating good adaptability to bottom-flow sluice gate designs.

[0004] Preferably, the outer blocking part is an annular column, and a groove-shaped channel is provided on the annular column at the position corresponding to the bottom channel.

[0005] Preferably, a plurality of annular support plates are provided on the bottom baffle, the annular support plates being connected to the bottom baffle via vertical connecting plates, the annular column passing through the annular support plates, and an auxiliary support bearing being provided between the annular column and the annular support plates. This application uses annular support plates in conjunction with a grooved channel for rotary opening and closing. Because this type of closed system uses rotary closing, blockage is less likely to occur; therefore, the operation and structural stability are good, allowing for long-term use.

[0006] Preferably, the power unit includes an end plate fixedly connected to the annular column. The end plate is connected to an L-shaped connecting rod. A transverse connecting rod is hinged to one end of the L-shaped connecting rod, and a U-shaped connecting rod is hinged to one end of the transverse connecting rod. The other end of the U-shaped connecting rod is hinged to a drive piston rod, which is coupled to a drive piston cylinder. The power unit of this application uses a forward-moving drive piston rod to move the U-shaped connecting rod, which in turn moves the L-shaped connecting rod, ultimately causing the end to rotate. Since this application does not consider large-angle rotation, it can stably drive the rotation of the end and has very high instrument drive reliability.

[0007] Preferably, the bottom baffle includes a bottom support plate located at the bottom, a vertical support plate is provided on the bottom support plate, a top support plate is provided on the upper part of the vertical support plate, and the bottom channel is provided through the vertical support plate.

[0008] Preferably, the bottom channel includes an abutment plate that is movably and sealingly abutted against the outer blocking part, a movable groove that cooperates with the outer blocking part is provided on the abutment plate, a flow channel is provided at the position of the abutment plate corresponding to the movable groove, and a flow pipe is provided at the rear of the abutment plate, the flow pipe passing through the vertical support plate.

[0009] Preferably, the annular column includes several sub-columns, with external threaded sections provided on both sides of each sub-column, and an external connecting pipe provided between the connected external threaded sections.

[0010] Preferably, fixed platforms are provided on both sides of the bottom baffle and the transverse dam body.

[0011] This application can bring the following beneficial effects:

[0012] 1. This application uses an external blocking part and a power part in combination, which can effectively control the opening and closing of the bottom channel, avoid blockage, and has good adaptability to the downward flow type.

[0013] 2. This application uses a ring-shaped support plate in conjunction with a grooved channel for rotary opening and closing. Because this type of closed system uses a rotary closing mechanism, it is not prone to blockage. Therefore, the operation and structural form are stable and can be used for a long time.

[0014] 3. The power unit of this application uses a drive piston rod to move forward, which drives the U-shaped connecting rod to move, and the U-shaped connecting rod in turn drives the L-shaped connecting rod to move, ultimately causing the end to rotate. Since this application does not consider large-angle rotation, the rotation drive of the end can be stably completed, and it has very high mechanical drive reliability. Attached Figure Description

[0019] Figure 4 This is a schematic diagram of the power unit. Detailed Implementation

[0020] To clearly illustrate the technical features of this solution, the following detailed description, in conjunction with the accompanying drawings, will be provided.

[0021] In the first embodiment, such as Figure 1 As shown, a downward flow sluice gate includes a bottom baffle 1 located at the bottom, a plurality of bottom channels 2 provided on the bottom baffle 1, and a transverse dam body 3 provided on the bottom baffle 1; an outer blocking part 4 is provided on the outside of the bottom channel 2, the outer blocking part 4 is movably sealed on the bottom channel 2, and a power part 5 for driving the outer blocking part 4 is provided on one side of the outer blocking part 4.

[0022] In use, the power unit 5 drives the outer blocking part 4 to open the bottom channel 2; when it is necessary to close the bottom channel 2, the power unit 5 drives in the opposite direction, so that the outer blocking part 4 closes the bottom channel 2, thus completing the operation.

[0023] In the second embodiment, as Figure 1-4 As shown, a downward flow sluice gate includes a bottom baffle 1 located at the bottom, a plurality of bottom channels 2 provided on the bottom baffle 1, and a transverse dam body 3 provided on the bottom baffle 1; an outer blocking part 4 is provided on the outside of the bottom channel 2, the outer blocking part 4 is movably sealed on the bottom channel 2, and a power part 5 for driving the outer blocking part 4 is provided on one side of the outer blocking part 4.

[0024] The outer blocking part 4 is an annular column 6, and a grooved channel 7 is provided on the annular column 6 corresponding to the position of the bottom channel 2. Several annular support plates 8 are provided on the bottom baffle 1. The annular support plates 8 are connected to the bottom baffle 1 through vertical connecting plates 9. The annular column 6 passes through the annular support plates 8. An auxiliary support bearing 10 is provided between the annular column 6 and the annular support plates 8. The power unit 5 includes an end plate 11 fixedly connected to the annular column 6. The end plate 11 is connected to an L-shaped connecting rod 12. A transverse connecting rod 13 is hinged to the end of the L-shaped connecting rod 12. A U-shaped connecting rod 14 is hinged to the end of the transverse connecting rod 13. The other end of the U-shaped connecting rod 14 is hinged to a drive piston rod 15. The drive piston rod 15 is configured to cooperate with a drive piston cylinder 16.

[0025] The bottom baffle 1 includes a bottom support plate 18 located at the bottom, a vertical support plate 19 disposed on the bottom support plate 18, and a top support plate 20 disposed on the upper part of the vertical support plate 19. The bottom channel 2 passes through the vertical support plate 19. The bottom channel 2 includes an abutment plate 21 that is movably and sealingly abutted against the outer blocking part 4. A movable groove 22 that cooperates with the outer blocking part 4 is disposed on the abutment plate 21. A flow channel 23 is disposed at the position of the abutment plate 21 corresponding to the movable groove 22. A flow pipe 24 is disposed at the rear of the abutment plate 21. The flow pipe 24 passes through the vertical support plate 19.

[0026] The annular column 6 includes several sub-columns 25, with external threaded sections 26 on both sides of each sub-column 25, and external connecting pipes 27 between the connected external threaded sections 26. Fixed platforms 28 are respectively provided on both sides of the bottom baffle 1 and the transverse dam 3.

[0027] In operation, the power unit 5 drives the outer blocking part 4, which in turn drives the piston rod forward, causing the U-shaped connecting rod to move. The U-shaped connecting rod then drives the L-shaped connecting rod, ultimately causing the end to rotate. This allows the outer blocking part 4 to open the bottom channel 2, which connects the trough-shaped channel 7 with the flow channel 23, allowing water to enter the flow channel 23 and flow pipe 24 from the trough-shaped channel 7. When it is necessary to close the bottom channel 2, the power unit 5 reverses the operation, driving the piston rod forward, which in turn drives the U-shaped connecting rod. The U-shaped connecting rod then drives the L-shaped connecting rod, ultimately causing the end to rotate. This causes the outer blocking part 4 to close the bottom channel 2, thus separating the trough-shaped channel 7 from the flow channel, completing the operation.

[0028] The above are merely embodiments of this application and are not intended to limit the scope of 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 scope of the claims of this application.
