[0030] Example

[0031] like Figure 1-5As shown, a diversion device for water conservancy construction includes two support plates 1 and a top plate 2. The top plate 2 is fixedly installed on top of the support plates 1. Several first ground nails 3 are provided at the bottom of the support plates 1. A first diversion box 4 and a second diversion box 15 are slidably arranged between the two support plates 1. The first diversion box 4 is a hollow structure with an open bottom. Several vent holes 5 are opened on the front side wall of the first diversion box 4. Several second ground nails 6 are provided at the bottom of the first diversion box 4. The support plates 1 provide support for the entire device and determine the location where diversion is required. When diverting water, the outer sides of the two support plates 1 are in contact with the river channel. Sealing devices, such as sealing gaskets or flood control bags, are usually used to prevent water from flowing out between the support plates 1 and the river channel. The first ground nails 3 can strengthen the stability of the connection between the support plates 1 and the ground. The water at the bottom of the canal is cut off by the first diversion box 4. The second ground nails 6 can strengthen the stability of the connection between the first diversion box 4 and the ground.

[0032] Specifically, when the first intercepting box 4 moves downward, the air inside the first intercepting box 4 is discharged through the vent 5, allowing water to be poured into the first intercepting box 4 from the opening at the bottom of the first intercepting box 4. This facilitates the smooth downward movement of the first intercepting box 4 and its insertion into the bottom of the water channel. At the same time, the water inside the first intercepting box 4 increases its weight, thereby improving its ability to withstand water pressure and enhancing the stability of the device.

[0033] In particular, when intercepting the flow, it is necessary to ensure that the vent 5 of the first intercepting box 4 faces the side with water, so as to prevent the water in the first intercepting box 4 from being discharged through the vent 5 after the interception is successful.

[0034] The first intercepting box 4 is equipped with a limiting device at its top. The second intercepting box 15 is located above the first intercepting box 4. The front and rear sides of the bottom of the second intercepting box 15 are equipped with intercepting plates 18. The limiting device limits the intercepting plates 18 and provides support for them, thereby enhancing their ability to withstand water pressure. The intercepting plates 18 are used to cut off the water in the channel.

[0035] In this embodiment, the first intercepting box 4 and the second intercepting box 18 are set separately, and an intercepting plate 18 is set at the bottom of the second intercepting box 18 so that the intercepting plate 18 can abut against the first intercepting box 4 during the descent. The reason is that during operation, the first intercepting box 4 first descends under the action of the first driving device, causing the second ground nail 6 to insert into the bottom of the water channel. At this time, there is a channel for water to flow between the first intercepting box 4 and the intercepting plate 18. The water flows continuously. When the intercepting plate 18 descends and abuts against the first intercepting box 4, it will contain the water between the two intercepting plates 18.

[0036] After the two intercepting plates 18 are lowered, they form a space with the support plates 1 on both sides. This space can accommodate a portion of the water flow, increasing the weight of the entire device and improving its stability. The second intercepting box 15 is set to cut off the water overflowing the intercepting plates 18, while also providing support for the top of the intercepting plates 18.

[0037] The top plate 2 is equipped with a first driving device and a second driving device. The first driving device drives the first intercepting box 4 to move up and down, and the second driving device drives the second intercepting box 15 to move up and down. The first driving device drives the first intercepting box 4 and the limiting device to move up and down, and the second driving device drives the second intercepting box 15 and the intercepting plate 18 to move up and down.

[0038] In some feasible embodiments, the limiting device includes two sets of limiting components and several support rods 10. The two sets of limiting components are respectively fixedly disposed on the front and rear sides of the top of the first intercepting box 4, and the several support rods 10 are fixedly disposed between the two sets of limiting components. The two ends of the several support rods 10 are respectively fixedly connected to the two sets of limiting components. The limiting components include a first limiting plate 7 and a second limiting plate 8. Both the first limiting plate 7 and the second limiting plate 8 are provided with several filter holes 9. The first limiting plate 7 is disposed on the outer side of the top of the first intercepting box 4, and the second limiting plate 8 is disposed on the inner side of the top of the first intercepting box 4. There is a gap between the first limiting plate 7 and the second limiting plate 8, and the gap width matches the intercepting plate 18. The filter holes 9 on the first limiting plate 7 and the second limiting plate 8 do not obstruct the flow of water when they descend with the first intercepting box 4, thus preventing the first limiting plate 7 or the second limiting plate 8 from tilting and being damaged due to excessive impact force of the water flow during descent. At the same time, the support rod 10 can also provide a certain support force for the two second limiting plates 8 to prevent them from tilting and being damaged. The intercepting plate 18 can be inserted into the gap between the first limiting plate 7 and the second limiting plate 8 as it moves down with the second intercepting box 15. Since the intercepting plate 18 will cut off the water flow when it moves down, it will be subjected to the impact force of the water flow. At this time, the first limiting plate 7 and the second limiting plate 8 are located on both sides of the intercepting plate 18, providing support for the intercepting plate 18. The first limiting plate 7, the intercepting plate 18 and the second limiting plate 8 jointly bear the impact force of the water flow, reducing the possibility of damage to the intercepting plate 18.

[0039] In some feasible embodiments, the front side wall of the second intercepting box 15 is provided with an elongated water inlet hole 16, and the left and right sides of the rear side wall of the second intercepting box 15 are provided with drain pipes 17. One end of the drain pipe 17 is connected to the inner cavity of the second intercepting box 15, and the other end of the drain pipe 17 is connected to an external water pipe. When the water level overflows the water inlet hole 16 on the second intercepting box 15, water will flow into the second intercepting box 15. When the water level in the second intercepting box 15 reaches the drain pipe 17, the water will be discharged through the drain pipe 17 and the external water pipe, which can control the water level and prevent the water level from overflowing the second intercepting box 15.

[0040] In some feasible embodiments, the first driving device has two sets of first driving components. Each first driving component includes a motor 13 and a screw 12. The top of the screw 12 is rotatably connected to the top plate 2, and the lower part of the screw 12 is connected to the first intercepting box 4 via a mounting block 11. The screw 12 and the mounting block 11 are threadedly connected. The motor 13 is fixedly mounted on the top plate 2, and its output end passes through the top plate 2 and is fixedly connected to the top of the screw 12. The motor 13 drives the screw 12 to rotate. Since the mounting block 11 and the screw 12 are threadedly connected, and the mounting block 11 cannot rotate but can only move up and down, the rotation of the screw 12 can drive the mounting block 11 to move up and down along the screw 12, thereby driving the first intercepting box 4 to move up and down.

[0041] In some feasible embodiments, the second driving device includes two hydraulic cylinders 19, which are fixedly mounted on the top plate 2. The telescopic ends of the hydraulic cylinders 19 penetrate the top plate 2 and are fixedly connected to the top of the second intercepting box 15. The operation of the hydraulic cylinders 19 drives the second intercepting box 15 to move up and down.

[0042] In some feasible embodiments, grooves 14 are provided on the opposite sides of the two support plates 1, and sliders matching the grooves 14 are provided on the left and right sides of the first intercepting box 4 and the second intercepting box 15. The sliders can limit the first intercepting box 4 and the second intercepting box 15 by sliding in the grooves 14, so as to prevent the first intercepting box 4 and the second intercepting box 15 from shifting when moving up and down.

[0043] In some feasible embodiments, the bottom of the second intercepting box 15 is provided with a limiting groove 20 that matches the first limiting plate 7 and the second limiting plate 8. When the intercepting plate 18 is fully inserted into the gap between the first limiting plate 7 and the second limiting plate 8, the tops of the first limiting plate 7 and the second limiting plate 8 are inserted into the limiting groove 20. At this time, the groove wall of the limiting groove 20 can provide support for the tops of the first limiting plate 7 and the second limiting plate 8, thereby improving the water pressure resistance of the first limiting plate 7 and the second limiting plate 8.

[0044] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that can be understood by those skilled in the art. The various embodiments of this disclosure have been described in detail above. To avoid obscuring the concept of this disclosure, some details known in the art have not been described. Those skilled in the art can fully understand how to implement the technical solutions disclosed herein based on the above description.
