Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy construction, in particular to a diversion device for water conservancy construction. Background Art

[0002] Water conservancy projects are projects built to control and allocate surface water and groundwater in nature to achieve the purpose of eliminating harm and promoting benefits. Water conservancy projects can be divided into flood control projects and hydropower projects. When dredging rivers or constructing other water conservancy projects, diversion devices are usually used to cut off the river and divert it to other places, so as to expose the riverbed for construction workers. Although traditional diversion devices can block and divert water, when there is a lot of sediment in the water, sediment will be deposited on one side of the diversion device during the process of blocking the water flow. Therefore, when there is a lot of sediment on one side of the diversion device, the lateral force on the baffle will increase, and when the lateral force is large, the overall stability of the diversion device will be destroyed, increasing the safety risk during construction. Therefore, in response to the above problems, a diversion device for water conservancy construction is proposed. Utility Model Content

[0023] Example 2

[0024] like Figure 1-3 As shown, in order to solve the problem that the stirring rod 5 has a poor stirring effect on the water at the front end of the baffle 1, the top end of the outer side of the stirring rod 5 is fixedly connected to a driving gear 9, and the outer side of the driving gear 9 is meshed with a driven gear 10, and the driven gear 10 is rotatably connected to the slider 4 through a rotating shaft, and the outer side of the driven gear 10 is meshed with a rack 11, and the rack 11 is fixedly connected to the baffle 1. In the process of controlling the reciprocating movement of the stirring rod 15, the driven gear 10 continuously meshes with the rack 11, and further meshes with the driving gear 9 to control the stirring rod 5 to rotate at the same time to stir the water at the front end of the baffle 1, so that the stirring rod 5 has a better stirring effect on the water at the front end of the baffle 1.

[0025] Example 3

[0026] like Figure 1-5 As shown, in order to solve the problem of not being able to prevent a large amount of impurities such as mud and sand in the water from adhering to the inner wall of the guide tube 3, the rear end of the guide tube 3 is fixedly connected to a fixed block 12, the rear end of the slider 4 is fixedly connected to a fixed rod 13 that penetrates the baffle 1, and the fixed rod 13 is slidably connected to the baffle 1, the bottom end of the fixed rod 13 is fixedly connected to a pull rope 14 that penetrates the fixed block 12, and the fixed block 12 is slidably connected to the pull rope 14, the bottom end of the pull rope 14 is fixedly connected to a reel 15, and the inner side of the reel 15 is fixedly connected to a fixed shaft 16 that penetrates the fixed block 12, and the fixed shaft 16 is connected to the fixed The fixed block 12 is rotatably connected, and the front end of the fixed shaft 16 is fixedly connected to a sleeve plate 18, and the inside of the sleeve plate 18 is slidably connected to a scraper 19 in contact with the inner wall of the guide tube 3.

At this time, the motor 6 will continuously drive the reciprocating screw 7 to rotate, and then under the limit of the limit block 8, the slider 4 will continuously drive the stirring rod 5 to reciprocate left and right. Because at this time the driven gear 10 will also engage the rack 11 and further engage the driving gear 9, the stirring rod 5 that reciprocates left and right will continue to rotate under the drive of the driving gear 9, thereby achieving the stirring of the front end of the baffle 1. At this time, by stirring the front end of the baffle 1, the silt is discharged through the diversion pipe 3 with the water flow, which can avoid the phenomenon of large amounts of silt silting at the front end of the baffle 1, thereby preventing the device from being affected by large lateral forces.
