However, current diversion pipes used in water conservancy construction still have the following problems in practical use:

[0003] Current water diversion pipes lack filtration and interception designs, making it easy for debris and other waste from river channels to enter the pipes, causing blockages, affecting drainage, leading to rising river levels, and impacting construction. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to propose a diversion pipe for hydraulic construction to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of this utility model provides a hydraulic construction guide pipe, including a guide pipe body. A slag discharge pipe is fixedly connected to the water inlet end of the guide pipe body. The slag discharge pipe is inclined and has several filter holes at positions corresponding to the guide pipe body. A water inlet is provided at the bottom of the slag discharge pipe on the side away from the guide pipe body. A lifting auger is rotatably connected to the center of the inner wall of the slag discharge pipe. A discharge pipe is fixedly connected to one side of the top of the slag discharge pipe and communicates with the top of the inner wall of the slag discharge pipe. Support frames are fixedly connected to both sides of the middle of the top surface of the slag discharge pipe. A first reducer is fixedly connected to the top of the support frame. The output end of the first reducer is fixedly connected to the top of the central shaft of the lifting auger. The diameter of the inner wall of the guide pipe body is adapted to the diameter of the inner wall of the slag discharge pipe.

[0008] The technical effect achieved by adopting the above scheme is that the speed can be reduced and the torque can be increased through the speed reduction transmission of the second reducer and the first reducer, so that the hydraulic force is not too large when driving the hoisting auger to rotate, so that it can be driven stably and reliably.

[0009] Preferably, in any of the above schemes, the output end of the second reducer is fixedly connected to a drive shaft, and the top end of the drive shaft is fixedly connected to the input end of the first reducer.

[0010] The technical effect achieved by adopting the above scheme is that the power output by the second reducer can be transmitted to the first reducer, realizing two-stage reduction and driving the auger to rotate stably.

[0011] Preferably, in any of the above embodiments, the outer wall of the guide tube is fixedly connected with a plurality of fixed bosses, and the plurality of fixed bosses are evenly distributed on the outer wall of the guide tube.

[0012] The technical effect achieved by adopting the above scheme is that the stability during embedding and the firmness of fixing can be improved by using several fixed bosses.

[0013] Preferably, in any of the above embodiments, the diameter of the lifting auger is adapted to the diameter of the inner wall of the slag discharge pipe, the length of the lifting auger is adapted to the length of the inner wall of the slag discharge pipe, and the size of the water inlet is larger than the size of the inner wall of the guide pipe.

[0014] The technical effect achieved by adopting the above solution is that the lifting auger can lift the impurities on the inner wall of the slag discharge pipe to a higher position, while matching the cross-sectional dimensions of the water inlet section with the cross-sectional dimensions of the inner wall of the guide pipe.

[0015] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0016] This hydraulic construction diversion pipe can intercept impurities and garbage in the river through several filter holes at the bottom of the slag discharge pipe, allowing water to enter the diversion pipe. At the same time, by rotating the lifting auger, the impurities intercepted at the bottom of the slag discharge pipe can be lifted upwards along the slag discharge pipe. After the impurities are pushed to the discharge pipe, they can automatically fall onto the platform of the buried pipe, allowing the impurities to be automatically discharged. This ensures that the filter holes maintain their filtration efficiency, keeps the water flow smooth, prevents blockage, and keeps the river water level stable. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0022] Example 1: As Figures 1 to 3 As shown, a hydraulic construction diversion pipe includes a diversion pipe body 1. A slag discharge pipe 2 is fixedly connected to the water inlet end of the diversion pipe body 1. The slag discharge pipe 2 is inclined. Several filter holes 13 are opened at the corresponding positions of the slag discharge pipe 2 and the diversion pipe body 1. A water inlet 3 is opened at the bottom of the slag discharge pipe 2 on the side away from the diversion pipe body 1. A lifting auger 4 is rotatably connected to the center of the inner wall of the slag discharge pipe 2. A discharge pipe 12 is fixedly connected to one side of the top of the slag discharge pipe 2. The discharge pipe 12 is connected to the top of the inner wall of the slag discharge pipe 2. Support frames 5 are fixedly connected to both sides of the middle of the top surface of the slag discharge pipe 2. A first reducer 6 is fixedly connected to the top of the support frame 5. The output end of the first reducer 6 is fixedly connected to the top of the central shaft of the lifting auger 4. The diameter of the inner wall of the diversion pipe body 1 is adapted to the diameter of the inner wall of the slag discharge pipe 2.

[0023] As an optional technical solution of this utility model, a hydraulic impeller 9 is rotatably connected to the middle of the inner wall of the guide pipe body 1 away from the slag discharge pipe 2. A second reducer 10 is fixedly connected to the outer wall of the guide pipe body 1 at the position corresponding to the hydraulic impeller 9. The input end of the second reducer 10 is fixedly connected to the top end of the central shaft of the hydraulic impeller 9. Through the reduction transmission of the second reducer 10 and the first reducer 6, the rotation speed can be reduced and the torque can be increased, so that the hydraulic force is not too large when driving the lifting auger 4 to rotate, so that it can be driven stably and reliably.

[0024] As an optional technical solution of this utility model, the output end of the second reducer 10 is fixedly connected to the transmission shaft 11, and the top end of the transmission shaft 11 is fixedly connected to the input end of the first reducer 6, so that the power output by the second reducer 10 can be transmitted to the first reducer 6 to achieve two-stage reduction and drive the lifting auger 4 to rotate stably.

[0025] As an optional technical solution of this utility model, the outer wall of the guide tube body 1 is fixedly connected with a number of fixed protrusions 7. The number of fixed protrusions 7 are evenly distributed on the outer wall of the guide tube body 1. The stability during embedding and the firmness of fixing can be improved by the number of fixed protrusions 7.

[0026] As an optional technical solution of this utility model, the diameter of the lifting auger 4 is adapted to the diameter of the inner wall of the slag discharge pipe 2, the length of the lifting auger 4 is adapted to the length of the inner wall of the slag discharge pipe 2, and the size of the water inlet 3 is larger than the size of the inner wall of the guide pipe body 1, so that the lifting auger 4 can lift the impurities on the inner wall of the slag discharge pipe 2 to a higher position, while making the water inlet cross section match the cross section size of the inner wall of the guide pipe body 1.

[0027] A diversion pipe for hydraulic construction operates on the following principle:

[0028] 1) Impurities and garbage in the river can be intercepted through several filter holes 13 at the bottom of the slag discharge pipe 2, and water can be allowed to enter the diversion pipe body 1;

[0029] 2) The water flow through the guide pipe body 1 can drive the hydraulic impeller 9 to rotate. This power drives the lifting auger 4 to rotate through the second reducer 10, the transmission shaft 11 and the first reducer 6.

[0030] 3) By rotating the auger 4, the impurities intercepted at the bottom of the slag discharge pipe 2 can be lifted upward along the slag discharge pipe 2. After the impurities are pushed to the position of the discharge pipe 12, they can automatically fall onto the platform of the buried pipe, so that the impurities are automatically discharged, so that the filter holes 13 maintain filtration efficiency and the water flow remains smooth.

[0031] In summary, this hydraulic construction diversion pipe can intercept impurities and garbage in the river through several filter holes 13 at the bottom of the slag discharge pipe 2, allowing water to enter the diversion pipe body 1. At the same time, by rotating the lifting auger 4, the impurities intercepted at the bottom of the slag discharge pipe 2 can be lifted upward along the slag discharge pipe 2. After the impurities are pushed to the discharge pipe 12, they can automatically fall onto the platform of the buried pipe, so that the impurities are automatically discharged. This ensures that the filter holes 13 maintain their filtration efficiency, keeps the water flow smooth, prevents blockage, and keeps the river water level stable.
