[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1 and Figure 2 A diversion device for water conservancy construction includes a trapezoidal diversion plate 1, which is fixed in a river channel to cut off the water flow. The diverted river channel is a planned and constructed river channel for water conservancy construction. A cushion layer is installed in the river channel. The bottom and both sides of the diversion plate 1 are attached together. A top support 2 is fixedly connected to the top of the diversion plate 1. The two ends of the top support 2 are fixed to the banks on both sides of the river channel. The top support 2 and the diversion plate 1 are fixed by anchor rods. Multiple water discharge channels 3 are evenly opened on the diversion plate 1.

[0026] like Figure 1 and Figure 2 The water discharge channel 3 is equipped with an adjustment mechanism. Each water discharge channel 3 has an adjustment mechanism, which includes an adjustment rod 4 rotatably connected to the bottom of the inner wall of the water discharge channel 3. An adjustment plate 5 is fixedly connected to the adjustment rod 4. The adjustment plate 5 is adapted to the water discharge channel 3 and is used to close the water discharge channel 3. The top of the adjustment rod 4 passes through the intercepting plate 1 and the top support 2 and extends to the outside of the top support 2. There are openings on the top of the intercepting plate 1 and the top support 2 to facilitate the passage of the adjustment rod 4. The adjustment rod 4 is located at the center of the corresponding water discharge channel 3. An adjustment gear 6 is fixedly connected to the top of the top support 2. A horizontally movable drive gear plate 7 is provided on the top support 2. The drive gear plate 7 meshes with the adjustment gear 6 and can drive the adjustment gear 6 to rotate.

[0027] like Figure 1 , Figure 3 and Figure 4The top of the top bracket 2 is fixedly connected to a guide rod 8, and a movable sleeve 9 is fixedly connected to one side of the drive tooth plate 7. The guide rod 8 and the movable sleeve 9 are slidably connected. The guide rod 8 passes through the movable sleeve 9 and guides the movement of the movable sleeve 9, so that both the movable sleeve 9 and the drive tooth plate 7 fixed to the movable sleeve 9 can only move horizontally.

[0028] like Figure 1 , Figure 3 and Figure 4 A fixing block 10 is fixedly connected to one side of the drive tooth plate 7. The fixing block 10 and the movable sleeve 9 are both located on the side of the drive tooth plate 7 without teeth. A first drive cylinder 11 is fixedly connected to the top of the top bracket 2. The output end of the first drive cylinder 11 is fixedly connected to the fixing block 10 and is used to drive the fixing block 10 and the drive tooth plate 7 to move horizontally.

[0029] like Figure 1 , Figure 3 and Figure 4 A sealing gasket 12 is fixedly connected to the inner wall of the water discharge channel 3. The sealing gasket 12 is a rubber sealing gasket. The sealing gasket 12 is in contact with the outer surface of the adjusting plate 5 to improve the sealing between the adjusting plate 5 and the water discharge channel 3. At the same time, the elasticity of the sealing gasket 12 does not affect the rotation of the adjusting plate 5.

[0030] like Figure 1 , Figure 3 and Figure 5 The top of the top bracket 2 is provided with a locking mechanism. The locking mechanism includes a fixed frame 13. A second drive cylinder 14 is fixedly connected to the top of the fixed frame 13. The first drive cylinder 11 and the second drive cylinder 14 are both existing technologies and are equipped with a power source. A movable connecting rod 15 is fixedly connected to the output end of the second drive cylinder 14. The movable connecting rod 15 is bent downward. The other end of the movable connecting rod 15 passes through one side of the fixed frame 13 and is fixedly connected to a locking tooth plate 16.

[0031] like Figure 1 , Figure 3 and Figure 5 The fixing frame 13 is fixedly connected to the top of the top bracket 2. The locking tooth plate 16 and the driving tooth plate 7 are engaged. When the teeth of the locking tooth plate 16 and the driving tooth plate 7 are interlocked and engaged together, the driving tooth plate 7 can be prevented from rotating.

[0032] The working principle of the interception device for water conservancy construction provided by this utility model is as follows:

[0033] In the initial state, the regulating plate 5 closes the water discharge channel 3, and the intercepting plate 1 cuts off the water flow in the river channel, thus realizing the interception of the water conservancy project;

[0034] When water needs to be drained, the second drive cylinder 14 first extends and drives the locking tooth plate 16 and the drive tooth plate 7 to separate via the movable connecting rod 15.

[0035] Then, control the first drive cylinder 11 to extend and retract to push the fixed block 10, which in turn drives the drive gear plate 7 to move. The drive gear plate 7 drives the adjusting gear 6 to rotate. The adjusting gear 6 drives the adjusting plate 5 to rotate through the adjusting rod 4. When the adjusting plate 5 rotates to different angles, it can release water at different flow rates, thus controlling the amount of water released.

[0036] After the angle adjustment of the adjusting plate 5 is completed, the second drive cylinder 14 retracts and drives the locking tooth plate 16 to move through the movable connecting rod 15, so that the locking tooth plate 16 and the drive tooth plate 7 are engaged and locked together. At this time, the drive tooth plate 7 cannot move, and the adjusting gear 6, the adjusting rod 4 and the adjusting plate 5 cannot rotate.

[0037] Compared with related technologies, the interception device for water conservancy construction provided by this utility model has the following beneficial effects:

[0038] This utility model uses multiple water discharge channels 3 in conjunction with the rotation of their internal adjustment mechanism to achieve both flow interception and control of water discharge volume by rotating the adjustment plates 5 at different angles. During water discharge, the water pressure can be distributed to multiple adjustment plates 5. With the meshing of the drive tooth plate 7 and the adjustment gear 6, as well as the locking tooth plate 16 meshing and locking the drive tooth plate 7, the impact force of the water flow on the adjustment plates 5 can be withstood, thus preventing the power equipment from being subjected to excessive load during water discharge and affecting the service life of the power equipment.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
