[0023] The utility model provides an adjustable flood control wall for water conservancy projects. Figure 1 The flood wall includes a bottom plate 1, two columns 2 are fixed on the bottom plate 1, and positioning grooves 21 are provided on opposite sides of the columns 2. The positioning grooves 21 include a positioning section 211 and an adjustment section 212. A first baffle 3 is fixed between the positioning sections 211. To ensure sealing, the first baffle 3 and the side wall of the positioning section 211 are kept sealed. Figure 2 As shown, the first baffle plate 3 is provided with an adjustment cavity 31 with an opening at the upper end, and the second baffle plate 4 is slidably connected to the adjustment cavity 31, and the side of the second baffle plate 4 is in contact with the adjustment section 212, so as to achieve a sealing and water-blocking effect. The second baffle plate 4 is provided with a vertical through hole 41, and the bottom of the through hole 41 is provided with an internal thread. An adjustment sleeve 42 is rotatably connected to the through hole 41, and an adjustment screw 43 is provided in the adjustment sleeve 42. The adjustment sleeve 42 and the adjustment screw 43 maintain a fixed circumferential position, that is, the rotation of the two is synchronized, and the adjustment screw 43 is threadedly connected to the internal thread, and the bottom end of the adjustment screw 43 maintains contact with the bottom wall of the adjustment cavity 31. The working principle of the flood wall is to rotate the adjusting sleeve 42 to rotate the adjusting screw 43 synchronously. At this time, the internal thread in the through hole 41 remains fixed, and when the adjusting screw 43 rotates, the second baffle 4 is pushed up or down through the threaded transmission. When in use, the operator can operate the adjusting sleeve 42 above the flood wall, which is particularly convenient for height adjustment when the flood has overflowed the flood wall.
[0024] like Figure 3As shown, a plurality of bearings 411 are fixed to the upper part of the through hole 41, and the adjusting sleeve 42 is inserted into the bearings 411, so that the adjusting sleeve 42 and the through hole 41 can rotate with each other through the bearings 411. At the same time, the bearings 411 are preferably bearings 411 with sealing effect, so as to prevent water from flowing into the adjusting chamber 31 through the through hole 41.
[0025] like Figure 2 As shown in FIG. 3 , a threaded sleeve 412 is fixed to the bottom of the through hole 41 , and the internal thread is disposed in the threaded sleeve 412 .
[0026] For easy operation, an adjustment block 421 is provided on the top of the adjustment sleeve 42 . A through hole 422 is provided on the adjustment block 421 . The user can insert a cross bar into the through hole 422 , thereby completing the rotation of the adjustment sleeve 42 with less effort.
[0027] like Figure 4 As shown, a positioning block 431 is provided at the top of the adjusting screw 43, and a positioning groove 423 is provided in the adjusting sleeve 42. The positioning block 431 is engaged with the positioning groove 423 to achieve the circumferential position fixation of the adjusting sleeve 42 and the adjusting screw 43.
[0028] In order to improve the impact resistance of the flood wall, a support push rod 11 is hinged on the base, and the other end of the support push rod 11 is hinged on the second baffle 4. The support push rod 11 is used to withstand the impact of water flow to prevent the flood wall from being knocked down by the water flow.
[0029] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
