[0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater in order to eliminate harm and promote benefits. Generally, they require the construction of different types of hydraulic structures such as dams, dikes, spillways, sluices, water inlets, channels, ferries, rafts, fishways, etc. to achieve their purposes.

[0003] When constructing hydraulic structures, it is generally necessary to build a diversion structure to guide the water flow. In the prior art, most diversion devices lack components for cleaning debris when in use. When too much debris accumulates inside, it is easy to cause blockage inside the guide pipe, which affects the circulation of water, thereby reducing the guiding effect of the water flow and lacking practicality. Therefore, it is necessary to redesign an efficient diversion device for water conservancy projects to address the above problems. Utility Model Content

DETAILED DESCRIPTION

[0023] A sealing gasket 9 is fixedly installed on the inner wall of the baffle 8. The sealing gasket 9 is made of rubber. The rubber surface is very soft and can be in close contact with the surface of the sealed component when subjected to external pressure, thereby preventing leakage of the medium. Moreover, rubber will not undergo chemical changes or be corroded when in contact with most liquids and gases. Therefore, it has a wide range of applications. Support plates 10 are fixedly installed on the inner walls of both sides of the diversion channel 1. The outer walls of the two support plates 10 are fixedly connected with an interception mesh plate 12 through an elastic mechanism. The elastic mechanism includes a spring telescopic rod 11 fixedly installed on the outer wall of the support plate 10. The telescopic end of the spring telescopic rod 11 is fixedly connected to the inner wall of the interception mesh plate 12. An extrusion block 13 is fixedly installed on the outer wall of the interception mesh plate 12. An extrusion groove is provided on the outer wall of the extrusion block 13. An extrusion shaft 14 and a crushing shaft 15 are rotatably installed inside the diversion channel 1. The outer walls of the extrusion shaft 14 and the crushing shaft 15 are fixedly installed with pulleys 16, and the two pulleys 16 are connected and driven by belts.

[0024] A cam 17 is fixedly installed on the outer wall of the extrusion shaft 14, and a second motor 19 connected to the extrusion shaft 14 is fixedly installed on the upper end surface of the guide channel 1 through a supporting mechanism. The supporting mechanism includes a supporting frame 18 fixedly installed on the upper end surface of the guide channel 1, and the second motor 19 is fixedly installed on the upper end surface of the support frame 18. A plurality of crushing blades 21 are fixedly installed on the outer wall of the crushing shaft 15 through a connecting mechanism. The connecting mechanism includes a connecting sleeve 20 fixedly installed on the outer wall of the crushing shaft 15, and each crushing blade 21 is fixedly installed on the outer wall of the connecting sleeve 20.

[0025] When the utility model is used, the first motor 4 drives the screw rod 3 to rotate, and the screw rod 3 drives the movable sleeve 6 to move by cooperating with the limit rod 5, and the movable sleeve 6 drives the baffle 8 to move by cooperating with the connecting rod 7, thereby the position of the baffle 8 can be conveniently adjusted, so that it can block and seal any one of the two guide tubes 2 through the cooperation of the sealing gasket 9, so that the diversion direction can be conveniently switched. When there are large individual debris inside the diversion channel 1, the second motor 19 drives the extrusion shaft 14 to rotate, and the extrusion shaft 14 drives the crushing shaft 15 to rotate through two pulleys 16 connected by belts. At this time, the crushing shaft 15 can drive the multiple crushing blades 21 to rotate through the connecting sleeve 20, thereby the large individual debris inside the diversion channel 1 can be crushed, thereby preventing the large individual debris from affecting the diversion effect;

[0026] The crushed debris can be intercepted and evacuated by the interception mesh plate 12, thereby preventing the crushed debris from accumulating too much and causing blockage to the two guide pipes 2. At the same time, the extrusion shaft 14 drives the cam 17 to rotate and contact the inner wall of the extrusion groove, thereby allowing the extrusion block 13 to be subjected to force to drive the interception mesh plate 12 to move and squeeze the spring telescopic rod 11. When the cam 17 is not in contact with the inner wall of the extrusion groove, the interception mesh plate 12 can be moved and reset under the elastic action of the spring telescopic rod 11. When the cam 17 continues to rotate and intermittently contacts the inner wall of the extrusion groove, the reciprocating shaking of the interception mesh plate 12 can be achieved through the cooperation of the two spring telescopic rods 11, thereby preventing the crushed debris from clogging the interception mesh plate 12.

[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
